Detailed Description

Hereinafter, embodiments of the connector according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

[ embodiment ]

One embodiment of a connector according to the present invention will be described with reference to fig. 1 to 9.

Reference numeral 1 in fig. 1 to 8 denotes a connector according to the present embodiment. The connector 1 includes a terminal fitting 10, a housing 20, and a shield cover 30 (fig. 4 and 8). In the connector 1, the terminal fitting 10 and the housing 20 are inserted and fitted into a tubular mating fitting portion (not shown), whereby the terminal fitting 10 is electrically connected to a mating terminal fitting (not shown) in the mating fitting portion. The connector 1 is inserted into and removed from the mating fitting portion along the cylindrical axis direction of the mating fitting portion.

For example, the connector 1 is electrically connected to a counterpart terminal fitting of a counterpart device (not shown) to electrically connect the counterpart device and a device (not shown) at the end of the electric wire We. The counterpart device includes: a metal housing, and a terminal block or a mating connector (not shown) for projecting a mating fitting portion from a mating wall of the housing to the outside. The mating fitting portion is formed in a circular or oval ring shape with a direction orthogonal to the planar wall surface of the mating wall body as a cylindrical axis direction, for example, a cross section orthogonal to the cylindrical axis direction. The connector 1 is fitted and connected to the mating fitting portion, thereby electrically connecting, for example, an inverter, which is a mating device mounted on a vehicle, and a rotating machine, which is a device mounted on an end portion of the electric wire We on the vehicle. The connector 1 shown here is fixed to a wall surface of a mating wall body in a state of being fitted and connected to a mating fitting portion.

The terminal fitting 10 is molded from a conductive material such as metal. The terminal fitting 10 includes: a terminal connection portion 11 physically and electrically connected to a counterpart terminal fitting; and an electric wire connection portion 12 physically and electrically connected to the tip end of the electric wire We (fig. 4 and 8). The terminal fitting 10 is mounted to the end of the electric wire We.

For example, for the terminal connecting portion 11 and the counterpart terminal connecting portion of the counterpart terminal fitting, one of them is formed in a female terminal shape, and the other is formed in a male terminal shape. Here, the terminal connecting portion 11 is formed in a cylindrical female terminal shape, and the counterpart terminal connecting portion is formed in a cylindrical male terminal shape fitted into the terminal connecting portion 11. In addition, the wire connection portion 12 is physically and electrically connected to the electric wire We by, for example, a core wire We1 crimped or welded to the tip end of the electric wire We.

The electric wire We shown here is a so-called shield electric wire, and includes: a cylindrical conductive core wire We 1; a cylindrical insulating inner sheath (inner sheath) We2 concentrically covering the core wire We 1; a cylindrical conductive braid We3 concentrically covering the inner sheath We 2; and a cylindrical insulating outer sheath (outer sheath) We4 (fig. 1 and 4) concentrically covering the braid We 3.

The terminal fitting 10 of this example is molded into a linear shape in which the terminal connecting portion 11 and the wire connecting portion 12 are arranged in a straight line. Therefore, the electric wire We is drawn out from the electric wire connection portion 12 in the extending direction of the terminal fitting 10 along the straight line. However, the terminal fitting 10 may be arranged such that the terminal connecting portion 11 and the wire connecting portion 12 intersect each other, for example, in an orthogonal arrangement.

The connector 1 shown here includes a combination of 2 pairs of terminal fittings 10 and electric wires We.

The case 20 is molded from an insulating material such as synthetic resin. The housing 20 accommodates the terminal fitting 10 and the electric wire We inside. In the housing 20, the terminal fitting 10 is held in the accommodated state, and the electric wire We is drawn out from the inside to the outside.

The housing 20 has a terminal accommodating portion 21 (fig. 1 to 8) for accommodating the terminal fitting 10 therein and inserting the terminal fitting into the mating fitting portion. The terminal accommodating portion 21 shown here is formed in a cylindrical shape and is inserted into and removed from the mating fitting portion along the cylindrical axis direction. In the housing 20 shown here, the terminal accommodating portions 21 are provided for each terminal fitting 10, and the respective terminal accommodating portions 21 are arranged in a direction orthogonal to the cylinder axis direction.

The housing 20 has a wire housing 22 (fig. 4 and 6 to 8) for housing the wire We drawn from the wire connecting portion 12 therein and for drawing the wire We from the inside to the outside. The wire housing 22 shown here is formed in a cylindrical shape and is arranged coaxially with the terminal housing 21. Therefore, the wire housing 22 leads the wire We led out from the wire connecting portion 12 from the inside to the outside in the same direction as the lead-out direction. In the housing 20 shown here, the wire housing portions 22 are provided for each terminal fitting 10, and the respective wire housing portions 22 are arranged in a direction orthogonal to the cylinder axis direction.

The housing 20 has an annular flange portion 23 between each of the terminal accommodating portions 21 and each of the wire accommodating portions 22, and the flange portion 23 projects radially outward from each of the terminal accommodating portions 21 and radially outward from each of the wire accommodating portions 22 (fig. 8).

The shield can 30 is formed of a metal material such as aluminum or an aluminum alloy. The shield case 30 accommodates the housing 20 and the electric wire We led out from the housing 20 to the outside. In the shield cover 30, the electric wire We drawn out from the electric wire housing portion 22 of the housing 20 is drawn out from the inside to the outside while the housing 20 is held at the housing completion position. In the shield case 30, the electric wire We drawn out from the wire housing 22 is drawn out from the inside to the outside in the same direction as the drawing direction.

The shield 30 includes a first cover member 40 and a second cover member 50 (fig. 1 to 8) that are assembled to each other.

The first cover member 40 shown here has: a cylindrical portion 41 formed in a cylindrical shape having a direction in which the electric wire We is drawn out (hereinafter, referred to as "wire drawing-out direction") as a cylindrical axis direction; and a split cylindrical portion 42 that leaves a part 41a of the annular end surface 41a from the annular end surface 41a of the cylindrical portion 41 in the wire drawing direction₁Partially protruding in the wire drawing direction (fig. 1, 2, and 4 to 8). On the other hand, the second cover member 50 shown here is formed in a split cylindrical shape, and is assembled to the split cylindrical portion 42 so as to be fitted with the split cylindrical portion 42 to form a cylindrical shape. That is, in the shield cover 30, one of the structures obtained by dividing the cylindrical shape into two parts is the divided cylindrical part 42, and the other is the second cover member 50.

The cylindrical portion 41 shown here is formed in an annular cylindrical shape having an oblong cross section perpendicular to the cylindrical axis direction. The cylindrical portion 41 shown here accommodates the flange 23-side portion of each terminal accommodating portion 21, the flange 23, and the flange 23-side portion of each wire accommodating portion 22. Therefore, the cylindrical portion 41 causes the respective wire housing portions 22 to protrude from the inside to the outside on the wire drawing direction side, and causes the respective terminal housing portions 21 to protrude from the inside to the outside on the side opposite to the wire drawing direction side.

The split tube 42 and the second cover member 50 may be formed in any shape as long as they are members that split the cylindrical shape into two parts. For example, the divided tube portion 42 and the second cover member 50 may be members that equally divide the tube shape into two parts, or one may be formed in a divided tube shape having an opening, and the other may be formed in a divided tube shape such as a lid that closes the opening.

The split tubular portion 42 and the second cover member 50 shown here are formed in a tubular shape assembled to each other, and are formed in an annular shape having an oblong cross section perpendicular to the axial direction of the tube. Here, the split tubular portion 42 and the second cover member 50 are formed in a split tubular shape that equally divides the tubular shape into two portions in one direction and the other direction in the short side direction of the oblong ring shape. The split tubular portion 42 and the second cover member 50 shown here house, in the tubular shape formed by assembling the two members, the projecting portion of each wire housing 22 projecting from the tubular portion 41 and the portion of each wire We drawn out from the wire housing 22 (hereinafter referred to as "wire drawing portion") Wea (fig. 6 and 7). In a state of a cylindrical shape in which the split cylindrical portion 42 and the second cover member 50 are assembled to each other, the electric wire We is drawn out to the outside from the openings of the one ends 40a and 50a on the electric wire drawing direction side (fig. 1).

In the second cover member 50 shown here, in order to prevent liquid such as water or saline from entering through the gap between the second cover member 50 and the tube 41 in the state where the second cover member 50 is assembled to the divided tube 42, the second cover member 50 has a portion 41a opposite to the annular end surface 41a of the tube 41₁And an opposing end surface 51 (fig. 4, 5, and 7) of the other end 50b opposite to the wire drawing direction side, which is disposed to face the wire drawing direction side. Therefore, in the connector 1, the part 41a of the annular end face 41a of the cylindrical portion 41 is formed so as to be able to fit the first cover member 40 and the second cover member 50 together₁The gap with the opposing end surface 51 of the other end 50b of the second cover member 50 is as narrow as possible.

In addition, in the split tube portion 42 and the second cover member 50 shown here, in order to prevent the wire lead-out portions Wea from coming into contact with each other inside the tubular shape, partition walls 42a, 52 interposed between the wire lead-out portions Wea protrude from the inner peripheral surface (fig. 5, 6, and 8). In the divided tube portion 42 and the second cover member 50, 2 semicircular arc-shaped inner circumferential surfaces 40c and 50c (fig. 4, 6, and 8) having the same diameter are formed by the partition walls 42a and 52, respectively. In addition, 2 cylindrical space portions are formed in the divided cylindrical portion 42 and the second cover member 50 in a cylindrical shape assembled to each other, and 1 wire lead-out portion Wea is disposed in each space portion. In the respective partition walls 42a, 52 shown here, at least the distal ends of the wire leading-out direction side ends 40a, 50a on the projecting direction side are formed as planar top surfaces, and the top surfaces are arranged to face each other in a cylindrical shape in which the split cylindrical portion 42 and the second cover member 50 are assembled.

The first cover member 40 and the second cover member 50 after assembly screw-fasten the fixing portions 43 and 53 provided at the one ends 40a and 50a on the wire drawing direction side to each other by an axial force in a direction orthogonal to the wire drawing direction (fig. 4 and 8). Therefore, in the first cover member 40, the fixing portion 43 is provided at the one end 40a of the split tube portion 42 on the wire drawing direction side. In the second cover member 50, a fixing portion 53 is provided at one end 50a on the wire drawing direction side.

In the shield case 30 shown here, the fixing portion 43 of the first cover member 40 is provided at the one end 40a on the wire drawing direction side of the partition wall 42a, and the fixing portion 53 of the second cover member 50 is provided at the one end 50a on the wire drawing direction side of the partition wall 52. Specifically, the fixing portion 43 of the first cover member 40 has a female screw portion 43a (fig. 5 and 8) into which the male screw portion B1 of the male screw member B is screwed. The female screw portion 43a has a hole axis direction defined as a direction perpendicular to the top surface of the wire drawing direction side end 40a of the partition wall 42 a. The fixing portion 53 of the second cover member 50 has a through hole 53a (fig. 5 and 8) through which the male screw portion B1 is inserted. The through hole 53a has a hole axis direction perpendicular to the top surface of the wire drawing direction side one end 50a of the partition wall 52. The fixing portions 43 and 53 are fixed by an axial force generated by screwing the male screw portion B1 and the female screw portion 43a of the male screw member B. The fixing portion 53 of the second cover member 50 receives an axial force from the seat surface B2 of the male screw member B, and the portion on which the axial force acts serves as a point of application of the axial force.

Further, on the inner circumferential surface side of the shield case 30, there are provided: a first direction locking wall 31 for locking the relative movement of the housing 20 at the accommodating completion position in the wire drawing direction; and a second direction locking wall 32 that locks the relative movement of the housing 20 at the accommodation completion position in the direction opposite to the wire drawing direction (fig. 5).

The first direction locking wall 31 is provided at least on the first cover member 40. The first direction locking wall 31 shown here is provided on the inner circumferential surface side of the cylinder portion 41 of the first cover member 40. Here, a wall surface that protrudes inward from the inner peripheral surface of the cylindrical portion 41 and faces in the direction opposite to the wire drawing direction is used as the first direction locking wall 31. The cylindrical portion 41 shown here has an annular wall surface 41b, and the annular wall surface 41b is a wall surface facing in the direction opposite to the wire drawing direction and is formed in an annular shape along the circumferential direction of the inner circumferential surface (fig. 5). In the cylinder 41, the annular wall surface 41b is used as the first direction locking wall 31. When the housing 20 is located at the accommodating completion position in the shield case 30, the first direction locking wall 31 is disposed to face the flange portion 23 of the housing 20 in the wire drawing direction side. The first direction locking wall 31 locks the flange portion 23 so as to hold the housing 20 at the accommodation completion position while allowing a relative movement amount of the play amount when the housing 20 attempts to move relatively to the shield case 30 in the wire drawing direction side. Therefore, in order to suppress the relative movement of the housing 20 in the wire drawing direction at the accommodating completion position, the flange portion 23 is used as a first-direction engaged wall that is engaged with the first-direction engaging wall 31.

The second direction locking wall 32 is provided in 1 each of the first cover member 40 and the second cover member 50. The second direction locking wall 32 shown here is provided between one end 50a and the other end 50b on the inner peripheral surface side of the divided tube portion 42 of the first cover member 40 and the inner peripheral surface side of the second cover member 50.

In the divided tube portion 42, a recess 42b formed by recessing the inner peripheral surface is formed on the side opposite to the wire drawing direction side with respect to the partition wall 42a, and a wall surface 42c of the recess 42b on the side opposite to the wire drawing direction side is protruded from the inner peripheral surface (fig. 5). In the divided cylinder 42, the wall surface 42c is used as the second direction locking wall 32. On the other hand, the housing 20 includes: an elastically deformable sheet body 24A having a wire drawing direction side as a free end and a side opposite to the wire drawing direction side as a fixed end; and a claw 24B provided at a free end of the plate 24A (fig. 5). The sheet body 24A protrudes from between the wire housing portions 22 of the flange portion 23, and elastically deforms in a direction orthogonal to the wire drawing direction and the arrangement direction of the wire housing portions 22. The claw 24B protrudes from the free end of the sheet body 24A so as to face the inner circumferential surface side of the divided cylinder portion 42 when the housing 20 is at the accommodation completion position.

In the inside of the shield case 30, when the housing 20 is located at the accommodation completion position, the claw 24B is accommodated in the recess 42B. When the housing 20 attempts to move relative to the shield cover 30 in the direction opposite to the wire drawing direction, the second direction locking wall 32 of the first cover member 40 locks the pawl 24B so as to hold the housing 20 at the accommodating completion position while allowing a relative movement amount corresponding to the play amount. Therefore, the claws 24B are used as second-direction locked walls that are locked to the second-direction locking walls 32 of the first cover member 40, and suppress relative movement of the housing 20 at the housing completion position in a direction opposite to the wire drawing direction.

On the other hand, in the second cover member 50, a protrusion 54 protruding from the inner peripheral surface is formed on the side opposite to the partition wall 52 in the wire drawing direction, and a wall surface of the protrusion 54 on the wire drawing direction side is used as the second direction locking wall 32 (fig. 5). On the other hand, the housing 20 is formed with a connecting wall 25, and the connecting wall 25 connects the outer peripheral surfaces of the respective wire housing portions 22 at one end on the wire drawing direction side, and fills one end on the wire drawing direction side of the recess 20a between the respective wire housing portions 22 (fig. 5 and 8). In the inside of the shield case 30, when the housing 20 is located at the accommodation completion position, the protrusion 54 is accommodated in the recess 20 a. When the housing 20 attempts to move relative to the shield cover 30 in the direction opposite to the wire drawing direction, the second direction locking wall 32 of the second cover member 50 locks the coupling wall 25 so as to hold the housing 20 at the accommodating completion position while allowing a relative movement amount of the play amount. Therefore, the coupling wall 25 serves as a second-direction locked wall that is locked to the second-direction locking wall 32 of the second cover member 50, and suppresses relative movement of the housing 20 at the accommodating completion position in a direction opposite to the wire drawing direction.

In the connector 1, the shield cover 30 is fixed to a wall surface of a mating wall body in a state of being fitted and connected to a mating fitting portion. The shield cover 30 has the other end 40b of the first cover member 40 on the side opposite to the wire drawing direction fixed to the wall surface of the opposite wall body (fig. 1 and 2). Therefore, the first cover member 40 has an annular flange portion 44 (fig. 1 and 2) projecting outward from the outer peripheral surface of the cylindrical portion 41 at the other end 40b of the cylindrical portion 41. The flange portion 44 is fixed to a wall surface of the opposite wall body by a screw member.

The connector 1 further includes an electrical connection member 61 (fig. 4 and 6 to 9) for electrically connecting the shield cover 30 to the braid We3 of the electric wire We. The electrical connection member 61 is molded from a conductive material such as metal. The electrical connection member 61 shown here is provided for each electric wire We. The electrical connection member 61 shown here is formed in a cylindrical shape, and concentrically covers the wire lead-out portion Wea inside thereof.

Here, the outer sheath We4 is peeled off from the tip of the electric wire We from the tip to the front of the wire lead-out portion We a, and the braid We3 on the tip side of the wire lead-out portion We a is folded back in a cylindrical shape to cover the outer peripheral surface of the outer sheath We 4. The electrical connection member 61 has a first cylindrical portion 61a, and the first cylindrical portion 61a concentrically covers a folded-back portion of the braid We3 from the outside (fig. 4 and 9). The first cylindrical portion 61a is concentrically covered from the outside by a cylindrical fixing member 62. The fixing member 62 is, for example, a so-called clamp ring formed of a conductive material such as metal, and is clamped and pressed against the first cylindrical portion 61a, whereby the first cylindrical portion 61a is physically and electrically connected to the folded-back portion of the braid We 3.

The electrical connection member 61 has a second cylindrical portion 61b (fig. 4 and 9) coaxial with the first cylindrical portion 61a and having an outer peripheral surface in contact with the inner peripheral surface of the shield cover 30. The outer peripheral surface of the second cylindrical portion 61b is physically and electrically connected to the semicircular inner peripheral surfaces 40c and 50c of the split cylinder portion 42 and the second cover member 50, respectively. Therefore, the second cylindrical portion 61b is formed to have an outer circumferential surface having a radius equal to the inner circumferential surfaces 40c and 50c of the split cylinder portion 42 and the second cover member 50, respectively. That is, the second cylindrical portion 61b is formed into a cylindrical portion having a larger diameter than the first cylindrical portion 61 a.

The electric connecting member 61 has a third cylindrical portion 61c (fig. 4) having a diameter larger than the first cylindrical portion 61a and smaller than the second cylindrical portion 61b, between the first cylindrical portion 61a and the second cylindrical portion 61b, and coaxially with the first cylindrical portion 61a and the second cylindrical portion 61 b.

The connector 1 further includes a first seal member 71 that fills a gap between the electric wire We and the shield shell 30 so that liquid entering from the outside does not reach the terminal fitting 10 (fig. 4 and 6 to 9). In order to improve the liquid-tightness, the connector 1 includes a second seal member 72 (fig. 4 and 6 to 9) that fills a gap between the electric wire We and the housing 20, inside the first seal member 71.

The first seal member 71 is an elastically deformable, for example rubber seal member, and is disposed between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield cover 30 in order to prevent liquid from entering between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield cover 30 from the outside. The first seal member 71 is formed in an annular shape that closes an annular gap between the outer peripheral surface of the electric wire We and the inner peripheral surface of the shield cover 30. The first seal member 71 is disposed on the other end 40b, 50b side of the first cover member 40 and the second cover member 50 from the point of application of the axial force to the fixing portions 43, 53 (fig. 4) at the one end 40a, 50a of the first cover member 40 and the second cover member 50, respectively.

The first seal member 71 shown here is provided for each electric wire We. Therefore, the first seal member 71 is formed in an annular shape, and the inner peripheral surface side is brought into close contact with the outer peripheral surface of the wire lead-out portion Wea at the end of the wire We, and the outer peripheral surface side is brought into close contact with the inner peripheral surfaces 40c and 50c of the divided cylindrical portion 42 and the second cover member 50, respectively.

In addition, the first sealing member 71 shown here has not only a function for ensuring the liquid-tightness between the electric wire We and the shield cover 30 but also a function for maintaining the electrical connection state between the shield cover 30 and the electrical connection member 61. Therefore, the first seal member 71 shown here brings the outer peripheral surface side into close contact with not only the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50, but also the inner peripheral surface of the electrical connection member 61, and causes a reaction force due to its elastic deformation to act on the inner peripheral surfaces 40c, 50c of the split tube portion 42 and the second cover member 50 and the inner peripheral surface of the electrical connection member 61. Further, the reaction force from the outer peripheral surface side due to the elastic deformation of the first seal member 71 acts directly on the inner peripheral surfaces 40c and 50c of the split tube portion 42 and the second cover member 50 from the outer peripheral surface side of the first seal member 71, and indirectly acts on the inner peripheral surfaces 40c and 50c of the split tube portion 42 and the second cover member 50 via the electrical connection member 61. The outer peripheral surface of the electrical connection member 61 is pressed against the inner peripheral surfaces 40c and 50c of the split tube portion 42 and the second cover member 50, respectively, by a reaction force from the outer peripheral surface side of the first seal member 71. In this way, the electrical connection member 61 is interposed between the inner peripheral surface of the shield shell 30 (the inner peripheral surfaces 40c and 50c of the split tube 42 and the second cover member 50) and the outer peripheral surface side of the first seal member 71, and can maintain a physically and electrically connected state with respect to the shield shell 30 by a reaction force from the outer peripheral surface side of the first seal member 71.

Specifically, the first seal member 71 has a plurality of annular inner peripheral lips 71a on the inner peripheral surface side and a plurality of annular outer peripheral lips 71b on the outer peripheral surface side (fig. 9).

In the first seal member 71, all the inner peripheral lip portions 71a are elastically deformed and brought into close contact with the outer peripheral surface of the outer sheath We 4.

On the other hand, in the first seal member 71, the outer peripheral lip 71b on the wire drawing direction side is elastically deformed to be brought into close contact with the inner peripheral surfaces 40c and 50c of the split tube portion 42 and the second cover member 50, respectively, and the outer peripheral lip 71b on the opposite side to the wire drawing direction side is elastically deformed to be brought into close contact with the inner peripheral surface of the second cylindrical portion 61b of the electrical connection member 61. Therefore, the first seal member 71 can cause the reaction force associated with the elastic deformation of the outer peripheral lip 71b on the wire drawing direction side to act on the inner peripheral surfaces 40c and 50c of the split tube portion 42 and the second cover member 50, respectively, and can cause the reaction force associated with the elastic deformation of the outer peripheral lip 71b on the side opposite to the wire drawing direction side to act on the inner peripheral surface of the second cylindrical portion 61b of the electrical connection member 61. The first seal member 71 presses the outer peripheral surface of the second cylindrical portion 61b against the inner peripheral surfaces 40c, 50c of the split cylindrical portion 42 and the second cover member 50 by causing a reaction force associated with elastic deformation of the outer peripheral lip portion 71b on the side opposite to the wire drawing direction side to act on the inner peripheral surfaces 40c, 50c of the split cylindrical portion 42 and the second cover member 50 through the second cylindrical portion 61 b. That is, the electric connecting member 61 is configured such that the second cylindrical portion 61b is interposed between the inner circumferential surface of the shield cover 30 (the inner circumferential surfaces 40c and 50c of the split cylindrical portion 42 and the second cover member 50, respectively) and the outer circumferential surface of the first sealing member 71 (the outer circumferential lip 71b on the side opposite to the wire drawing direction side) by inserting the first sealing member 71 on the side opposite to the wire drawing direction side into the second cylindrical portion 61 b. Therefore, in the second cylindrical portion 61b, the outer circumferential surface thereof can be continuously physically and electrically connected to the inner circumferential surfaces 40c and 50c of the split cylindrical portion 42 and the second cover member 50, respectively, by the reaction force from the outer circumferential lip 71b on the side opposite to the wire drawing direction side.

The first seal member 71 also fills the annular gap between the outer peripheral surface of the electric wire We and the inner peripheral surface of the second cylindrical portion 61b, and therefore, the liquid can be prevented from entering the electric connecting member 61.

The second seal member 72 is an elastically deformable, for example rubber seal member, and is disposed between the outer peripheral surface of the electric wire We and the inner peripheral surface of the housing 20 in order to prevent liquid from entering between the outer peripheral surface of the electric wire We and the inner peripheral surface of the housing 20 from the outside. In addition, the second seal member 72 is also disposed between the outer peripheral surface of the electrical connection member 61 and the inner peripheral surface of the shield cover 30 in order to suppress liquid from entering between the outer peripheral surface of the electrical connection member 61 and the inner peripheral surface of the shield cover 30 from the outside. Therefore, the second seal member 72 includes: a first annular portion 72a that closes an annular gap between the outer peripheral surface of the electric wire We and the inner peripheral surface of the housing 20; and a second annular portion 72b (fig. 9) that closes an annular gap between the outer peripheral surface of the electrical connection member 61 and the inner peripheral surface of the shield cover 30. The second seal member 72 has an annular coupling portion 72c (fig. 9) that coaxially couples the first annular portion 72a and the second annular portion 72 b. The second seal member 72 is disposed on the opposite side of the first seal member 71 from the wire drawing direction.

The second seal member 72 shown here is provided for each electric wire We. Therefore, the first annular portion 72a, the second annular portion 72b, and the coupling portion 72c of the second seal member 72 are each formed in an annular shape. The first annular portion 72a has an inner peripheral surface side closely contacting the outer peripheral surface of the wire lead-out portion Wea at the end of the wire We, and has an outer peripheral surface side closely contacting the inner peripheral surface of the wire housing 22. In this example, the inner circumferential surface side of the first annular portion 72a is brought into close contact with the outer circumferential surface of the inner sheath We2 of the wire lead-out portion We a. The second annular portion 72b has an inner peripheral surface closely attached to the outer peripheral surface of the electrical connection member 61, and has an outer peripheral surface closely attached to the inner peripheral surfaces 40c and 50c of the divided tube portion 42 and the second cover member 50, respectively.

Specifically, the first annular portion 72a is disposed in the electric wire housing 22The opening side in the wire drawing direction is disposed on the side opposite to the wire drawing direction side with respect to the folded braid We3 and the electrical connection member 61 in the wire drawing portion Wea. The first annular portion 72a has a plurality of annular inner peripheral lips 72a on the inner peripheral surface side₁And an annular outer peripheral lip 72a on the outer peripheral surface side₂(FIG. 9). In the first annular part 72a, all the inner peripheral lip parts 72a are formed₁Elastically deformed while closely contacting the outer peripheral surface of the inner skin We2, and the entire outer peripheral lip portion 72a₂Elastically deformed while being closely attached to the inner peripheral surface of the wire housing 22.

The second annular portion 72b is disposed on the opposite side of the first seal member 71 and the second cylindrical portion 61b of the electrical connection member 61 in the wire drawing direction and on the side of the first cylindrical portion 61a of the electrical connection member 61 in the wire drawing direction. The second annular portion 72b has a plurality of annular inner peripheral lips 72b on the inner peripheral surface side₁And an annular outer peripheral lip 72b on the outer peripheral surface side₂(FIG. 9). In the second annular portion 72b, all the inner peripheral lip portions 72b are formed₁Elastically deformed and brought into close contact with the outer peripheral surface of the third cylindrical portion 61c of the electrical connection member 61, thereby making all the outer peripheral lip portions 72b₂Elastically deforms and comes into close contact with the inner circumferential surfaces 40c and 50c of the split tubular portion 42 and the second cover member 50, respectively.

In this way, in the connector 1, the first seal member 71 and the second seal member 72 are disposed between the one end 50a and the other end 50b of the second cover member 50 as viewed from the second cover member 50. The first seal member 71 is disposed at a portion of the one end 50a of the second cover member 50 closer to the other end 50b of the second cover member 50 than the point of application of the axial force to the fixing portion 53, and is elastically deformed in a radially compressed state between the outer peripheral surface of the electric wire We (the outer peripheral surface of the wire lead-out portion Wea) and the inner peripheral surface of the shield cover 30 (the inner peripheral surfaces 40c, 50c of the split tubular portion 42 and the second cover member 50, respectively). A reaction force directed radially outward due to elastic deformation of the first seal member 71 acts on the inner peripheral surface 50c of the one end 50a of the second cover member 50 from the outer peripheral surface side.

Here, the second cover member 50 and the like are shielded for light weight and small sizeThe cover 30 will be as thin as possible. Therefore, the shield cover 30 may be elastically deformed by the external force. In the second cover member 50 shown here, in a state where the male screw member B is fastened to the female screw portion 43a, the point of application of the axial force to the fixing portion 53 on the one end 50a side becomes a fulcrum, and the point of application of the reaction force from the first seal member 71 to the inner circumferential surface 50c on the one end 50a side becomes a point of force, so that the other end 50B side may be opposed to the part 41a of the annular end surface 41a of the cylindrical portion 41 of the first cover member 40₁And (4) tilting. In particular, in the connector 1 shown here, the second cylindrical portion 61b of the electrical connection member 61 is present between the second cover member 50 and the first seal member 71 on the side opposite to the wire drawing direction side, and the amount of elastic deformation on the side opposite to the wire drawing direction side is larger than on the wire drawing direction side on the outer peripheral surface side of the first seal member 71, and therefore, there is a possibility that the second cylindrical portion 61b is expanded radially outward by a larger reaction force on the side opposite to the wire drawing direction side than on the wire drawing direction side. Therefore, in the connector 1 shown here, the second cylindrical portion 61b may deform in accordance with the reaction force from the first seal member 71, and the other end 50b side of the second cover member 50 may lift.

Therefore, in the connector 1, the other end 50b side of the second cover member 50 is moved and locked relative to the first cover member 40 in accordance with the axial force acting on the fixing portion 53 of the second cover member 50 and the reaction force of the first seal member 71 against the inner peripheral surface 50c of the second cover member 50. Specifically, the first cover member 40 includes a locking portion 45 (fig. 5, 6, and 8) for locking the relative movement of the locked portion 55 at the other end 50b of the second cover member 50.

In the first cover member 40, a part 41a of the annular end face 41a of the cylindrical portion 41₁The side is provided with a locking portion 45. The second cover member 50 is provided with an engaged portion 55 at the other end 50b thereof.

Specifically, the first cover member 40 includes: a first outer groove 46A and a second outer groove 46B formed in a part 41a of the annular end surface 41a of the tube 41₁A ring arranged on one side and the other side of the cylinder part 41 in the circumferential direction with a gapThe outer peripheral surface of the cylindrical portion 41 of the tubular end surface 41a is laterally offset in the direction opposite to the wire drawing direction; an inner groove 46C formed in a part 41a of the annular end surface 41a of the cylindrical portion 41₁A side that shifts an inner peripheral surface side of the cylindrical portion 41 of the annular end surface 41a in a direction opposite to the wire drawing direction between the one side and the other side in the circumferential direction of the cylindrical portion 41; and an outer wall portion 46D which is disposed between the first outer groove portion 46A and the second outer groove portion 46B and closer to the outer circumferential surface side of the tube portion 41 than the inner groove portion 46C (fig. 6). In the first cover member 40, the outer wall portion 46D is used as the engaging portion 45. Specifically, a wall surface of the outer wall portion 46D on the side of the inner groove portion 46C is used as the locking portion 45.

In addition, the second cover member 50 includes: a first fitting portion 56A that protrudes from the outer peripheral surface side of the opposing end surface 51 of the other end 50b in the direction opposite to the wire drawing direction and is fitted into the first outer groove portion 46A in a state where the second cover member 50 is assembled to the first cover member 40; a second fitting portion 56B that protrudes from the outer peripheral surface side of the opposing end surface 51 of the other end 50B in the direction opposite to the wire drawing direction, and is fitted into the second outer groove portion 46B in a state where the second cover member 50 is assembled to the first cover member 40; a notch 56C formed between the first fitting portion 56A and the second fitting portion 56B, into which the outer wall portion 46D of the first cover member 40 is fitted in a state in which the second cover member 50 is assembled to the first cover member 40; and a third fitting portion 56D that protrudes from the inner peripheral surface side of the opposing end surface 51 of the other end 50b in a direction opposite to the wire drawing direction at a position closer to the inner peripheral surface side of the second cover member 50 than the notch 56C, and that is fitted into the inner groove portion 46C in a state where the second cover member 50 is assembled to the first cover member 40 (fig. 6 and 7). In the second cover member 50, the third fitting portion 56D is used as the engaged portion 55. Specifically, the wall surface of the third fitting portion 56D on the side of the notch 56C is used as the engaged portion 55.

In this connector 1, in the process of screwing the fixing portions 43 and 53, the inner peripheral surface 50c of the second cover member 50 directly receives the reaction force from the first seal member 71 on the wire drawing direction side of the first seal member 71, and indirectly receives the reaction force from the first seal member 71 via the second cylindrical portion 61b on the opposite side of the first seal member 71 from the wire drawing direction side. Therefore, in the connector 1, during the screwing process, the other end 50b side of the second cover member 50 is intended to move relative to the first cover member 40 with the one end 50a side as a fulcrum, so that the other end 50b of the second cover member 50 is tilted, but the relative movement of the engaged portion 55 at the other end 50b of the second cover member 50 is engaged with the engaging portion 45 of the first cover member 40 in the inner groove portion 46C.

In the connector 1, even in a state where the fixing of the screws to the fixing portions 43 and 53 is completed, the inner peripheral surface 50c of the second cover member 50 directly receives the reaction force from the first seal member 71 on the wire drawing direction side of the first seal member 71, and indirectly receives the reaction force from the first seal member 71 through the second cylindrical portion 61b on the side opposite to the wire drawing direction side of the first seal member 71. Therefore, in the connector 1, in the state where the screw fastening is completed, the gap between the first cover member 40 and the second cover member 50 (specifically, the part 41a of the annular end surface 41a in the cylindrical portion 41) is not enlarged₁A gap from the opposing end surface 51 of the other end 50b of the second cover member 50), the relative movement of the engaged portion 55 at the other end 50b of the second cover member 50 is engaged by the engaging portion 45 of the first cover member 40 in the inner groove portion 46C. Therefore, in the connector 1 of the present embodiment, since the other end 50b of the second cover member 50 can be prevented from being lifted relative to the first cover member 40 in response to the axial force at the fixing portions 43 and 53 and the reaction force from the first seal member 71 at the inner peripheral surface 50c of the second cover member 50, the liquid can be prevented from flowing through the gap between the first cover member 40 and the second cover member 50 (specifically, the portion 41a of the annular end surface 41a of the cylindrical portion 41)₁A gap between the opposing end surface 51 of the other end 50b of the second cover member 50) to improve water stopping performance.

The connector 1 is provided with a first outer groove 46A and a first fitting portion 56A that are fitted to each other, and a second outer groove 46B and a second fitting portion 56B that are fitted to each other. Therefore, in the connector 1, the first outer groove can be securedThe creepage distance between the portion 46A and the first fitting portion 56A and the creepage distance between the second outer groove portion 46B and the second fitting portion 56B suppress the liquid from reaching the part 41a of the annular end surface 41a of the tube portion 41 through the gap therebetween₁And the opposing end surface 51 of the other end 50b of the second cover member 50. In the connector 1, the engagement function of the engagement portions 45 and the engaged portions 55 also suppresses the expansion of the gap between the first outer groove portion 46A and the first fitting portion 56A and the gap between the second outer groove portion 46B and the second fitting portion 56B, and thus the creepage distance therebetween can be maintained. Therefore, the connector 1 can further improve the water stopping performance.

Further, although the outer wall portion 46D and the notch 56C are provided to be fitted to each other in the connector 1, the engagement function of the engagement portion 45 and the engaged portion 55 can also suppress the expansion of the gap between the outer wall portion 46D and the notch 56C, and thus the liquid can be suppressed from reaching the part 41a of the annular end surface 41a of the cylindrical portion 41 through the gap₁And the opposing end surface 51 of the other end 50b of the second cover member 50. Therefore, the connector 1 can also improve the water stopping performance from this point of view.

In the connector 1, 1 of the 2 second-direction locking walls 32 is provided in the second cover member 50. The second direction locking wall 32 of the second cover member 50 is provided between one end 50a and the other end 50b of the second cover member 50 on the inner peripheral surface side. More specifically, the second direction locking wall 32 of the second cover member 50 is provided between the point of action of the reaction force from the first seal member 71 on the one end 50a of the second cover member 50 and the locked portion 55 on the other end 50 b. The second direction locking wall 32 is inserted into the recess 20a of the housing 20 assembled to the first cover member 40 by assembling the first cover member 40 and the second cover member 50, and is in a state of being capable of locking with the connecting wall 25 of the housing 20. Therefore, when the other end 50b of the second cover member 50 is raised relative to the first cover member 40 with the one end 50a side as a fulcrum, the second direction locking wall 32 may come out of the recess 20a of the housing 20 and may not be locked to the connecting wall 25 of the housing 20. In the connector 1, the other end 50b of the second cover member 50 may be lifted up from the split tubular portion 42 in the first cover member 40, and in this case, the locking function of the housing 20 by the second direction locking wall 32 of the split tubular portion 42 may not function. However, in the connector 1, since the locking function by the locking portion 45 and the locked portion 55 is provided, as described above, the tilting of the other end 50b of the second cover member 50 can be suppressed, and therefore, the accommodated state of the second direction locking wall 32 of the second cover member 50 with respect to the recess 20a can be continuously maintained, and the locking function of the second direction locking wall 32 of the split tubular portion 42 can be continuously maintained. Therefore, the connector 1 of the present embodiment can continuously maintain the assembled state of the housing 20 and the shield shell 30 while improving the water stop performance.
