Technical Field

The present disclosure relates to connectors.

Background

Patent document 1 discloses a device connector which is mounted on a wall portion of a housing for housing a circuit board. In order to suppress the increase of the pressure in the housing due to the heat generation of the circuit board, the device connector is provided with a vent hole for communicating the inside and the outside of the housing.

Here, when the vent hole is formed in the connector housing of the device connector, the vent hole can be formed in the connector housing by disposing a pin for forming the vent hole in a molding die of the connector housing and pulling out the pin after the connector housing is molded. But in this case the following is considered: the pin is likely to become slender, and the pin is broken when the connector housing is molded, and the vent hole is not formed well.

Therefore, in the connector for device described in patent document 1, 2 primary molded bodies each holding a terminal fitting and a connector housing obtained by insert molding using the 2 primary molded bodies as cores are used, and the vent holes are formed by overlapping the 2 primary molded bodies. Specifically, a groove portion is formed in the abutting surface of one primary molded body, and 2 primary molded bodies are stacked so that the opening side of the groove portion is covered with the abutting surface of the other primary molded body, thereby forming a vent inside the groove portion.

In the device connector described in patent document 1, the groove portion is formed so as to straddle 2 abutting surfaces adjacent to each other so as to be orthogonal to each other in the primary molded body. In the connector described in patent document 1, the groove portion formed in the planar mating surface of the primary molded body is linear.

Disclosure of Invention

Problems to be solved by the invention

However, depending on the arrangement and shape of the first terminals, the second terminals, and the like formed on the first core and the second core, it is also conceivable that the groove portions for the vent holes cannot be formed linearly in the planar abutting surfaces. That is, according to the structure of the groove portion in patent document 1, since the groove portion interferes with the first terminal, the second terminal, and the like, it is sometimes difficult to form the groove portion appropriately.

The present disclosure has been made in view of the above problems, and provides a connector in which a groove portion is easily and appropriately formed.

Means for solving the problems

One aspect of the present disclosure is a connector that forms an internal space for housing a circuit board together with a housing, the connector including:

a plurality of first terminals;

a first core that exposes both end portions of the first terminal and holds the first terminal;

a plurality of second terminals;

a second core that overlaps the first core so as to face the first core, exposes both end portions of the second terminal, and holds the second terminal;

a housing covering at least a portion of the first core and at least a portion of the second core; and

an air passage communicating the internal space with the atmosphere,

at least a part of the air passage is formed by a groove portion formed in at least one of overlapping surfaces of the first core and the second core,

the groove portion has a curved shape in the overlapping plane.

Effects of the invention

In the connector of the above aspect, the groove portion for the vent passage has a curved shape in the overlapping plane. Therefore, even if the groove portion is formed linearly, the groove portion may interfere with the first terminal formed in the first core, the second terminal formed in the second core, and the like, but the groove portion may not interfere with the first terminal, the second terminal, and the like.

As described above, according to the above aspect, a connector in which the groove portion is easily and appropriately formed can be provided.

The first core 5 has: a first pedestal core portion 52 formed in a plane direction parallel to the circuit substrate 12; and a first tower core 51 projecting from the first pedestal core 52 toward the opposite side of the internal space 13 side of the case 11 in the normal direction of the circuit board 12 (hereinafter referred to as "Z direction"). The side of the first tower core 51 projecting from the first base core 52 in the Z direction will be referred to hereinafter as the Z1 side, and the opposite side to the Z1 side will be referred to hereinafter as the Z2 side.

The first tower core 51 has a thickness in the X direction orthogonal to the Z direction. As shown in fig. 8 and 9, an overlapping surface that overlaps with a second tower core portion 61, described later, of the second core 6 is formed on one surface of the first tower core portion 51 in the X direction. Hereinafter, a surface of the first tower core 51 overlapping the second tower core 61 is referred to as a first overlapping surface 511, and a surface of the second tower core 61 overlapping the first overlapping surface 511 of the first tower core 51 is referred to as a second overlapping surface 611. One side in the X direction and the side of the second tower core 61 with respect to the first tower core 51 is referred to as an X2 side, and the opposite side to the X2 side is referred to as an X1 side.

The first overlapping surface 511 is formed in a planar shape orthogonal to the X direction. As shown in fig. 10, a tower groove constituting the groove portion 512 is formed on the first overlapping surface 511 of the first tower core 51. The tower slots constitute at least a part of said venting path 14. In the present embodiment, the groove portion 512 is formed only by the tower groove, and the groove portion 512 will be referred to as the tower groove 512 hereinafter.

As shown in fig. 8, the tower groove 512 is formed in such a manner that a portion of the first overlapping surface 511 is depressed. As shown in fig. 5 and 6, the tower groove 512 is formed with: in a cross section orthogonal to the forming direction thereof, the inner space of the tower groove 512 is formed in a quadrangular shape. As shown in fig. 10 and 11, the tower groove 512 is formed to be elongated in the Z direction.

The tower groove 512 has a bent crank shape in the first overlapping surface 511. The tower groove 512 has an outer groove 512a, a connecting groove 512b, and an inner groove 512 c.

The outer groove 512a is formed to be elongated in the Z direction. As shown in fig. 10, the outer groove portion 512a is located at substantially the center of the first overlapping surface 511 in the Y direction. The Y direction is a direction orthogonal to both the X direction and the Z direction.

As shown in fig. 10 and 11, the connecting groove portion 512b is formed along the Y direction from the end portion of the outer groove portion 512a on the Z2 side toward the Y direction side. The length of the connecting groove portion 512b in the Y direction is shorter than the length of the outer groove portion 512a in the Z direction.

The inner groove 512c is formed from the end of the connecting groove 512b opposite to the side communicating with the outer groove 512a in the Y direction toward the Z2 side. The inner groove 512c is formed to be elongated in the Z direction at a position offset in the Y direction with respect to the outer groove 512 a. The inner groove 512c is formed closer to the inner space 13 of the case 11 in the ventilation path 14 than the outer groove 512 a. The inner groove 512c is formed straight in the Z direction, and has an open end at the Z2 side. Hereinafter, the side of the outer groove 512a with respect to the inner groove 512c in the Y direction is referred to as the Y1 side, and the opposite side to the Y1 side is referred to as the Y2 side.

As shown in fig. 4, the open portion of the Z2-side end of the inner groove 512c communicates with the internal space 13 via a second hole 621, described later, formed in the second core 6 and a third hole 721, formed in the third core 7, described later. The second hole 621 and the third hole 721 constitute a part of the ventilation passage 14 together with the tower groove 512.

As shown in fig. 6, 9, 10, and 11, a through-hole 513 is formed from the end of the bottom of the outer groove 512a of the first tower core 51 on the Z1 side toward the X1 side. The through-hole 513 is formed so as to penetrate the first tower core 51 in the X direction. The through-hole 513 is formed as: in a cross section orthogonal to the longitudinal direction (X direction), the inner space of the through-hole 513 is circular. As shown in fig. 6 and 11, the through-hole 513 is formed to penetrate between the pair of first terminals 2. The first terminal 2 is not exposed to the through-hole 513.

As shown in fig. 6, a case opening 810 of the case 8 is formed on the X1 side of the through-hole 513. The housing opening 810 is an opening for opening the through-hole 513 to the atmosphere. The tower tank 512 communicates with the atmosphere through the through hole 513 and the housing opening 810. The through hole 513 and the housing opening 810 constitute a part of the ventilation passage 14 together with the tower groove 512.

As shown in fig. 10 and 11, a plurality of concave portions (a first concave portion 514a, a second concave portion 514b, a third concave portion 514c, and a fourth concave portion 514d) are formed on the first overlapping surface 511. As shown in fig. 5, the concave portion is a groove into which a later-described convex portion formed on the second core 6 is inserted and fitted.

The first concave portions 514a are formed straight in the Z direction on the Y2 side of the entire tower groove 512 on the first overlapping surface 511. In the Z direction, the first concave portions 514a are formed over the entire formation region of the stepped groove 512 in the Z direction. The Z2 side end of first concave strip 514a is open.

The second concave portion 514b has a portion formed in the Y direction so as to extend along the connecting groove portion 512b on the Z2 side of the connecting groove portion 512b of the tower groove 512, and a portion formed in the Z direction so as to extend along the inner groove portion 512c on the Y1 side of the inner groove portion 512c of the tower groove 512, and is L-shaped as a whole. The second concave portion 514b is formed parallel to the connecting groove portion 512b and the inner groove portion 512 c. The ends of the second concave portions 514b on the Z2 side are open on the Z2 side. Second concave portion 514b is formed in the vicinity of connecting groove portion 512b and inner groove portion 512 c.

The third concave portions 514c are formed straight in the Z direction at the Y1 side end of the first overlapping surface 511. The third concave portions 514c are formed along the outer groove portions 512a on the Y1 side of the outer groove portions 512 a. Third concave portion 514c is formed on the Y1 side of second concave portion 514 b. In the Z direction, the third concave portion 514c is formed from the position of the end portion on the Z1 side of the stepped groove 512 to the position on the Z2 side of the position of the end portion on the Z2 side of the outer groove 512 a. The end of the third concave portion 514c on the Z2 side is formed at a position overlapping the end of the second concave portion 514b on the Z1 side in the Y direction.

The fourth concave portions 514d are formed on the Z2 side end portion of the Y2 side end portion of the first overlapping surface 511. Fourth concave portion 514d is formed on the Z2 side of third concave portion 514 c. As shown in fig. 8 to 10, the first pedestal core portion 52 is formed from the Z2-side end portion of the first tower core portion 51.

The first base core 52 is formed in a planar shape orthogonal to the Z direction. The first pedestal core 52 is formed from the first tower core 51 toward the X1 side, and protrudes further toward the Y1 side than the first tower core 51. The end of the first terminal 2 on the side connected to the circuit board 12 protrudes from the Y1-side end of the first pedestal core 52 toward the Z2 side.

[ first terminal 2 ]

As shown in fig. 11, the first protruding terminal portions 21, which are the end portions of the pair of first terminals 2, protrude from the Z1-side end portion of the first tower-shaped core portion 51 toward the Z1 side. The first protruding terminal portions 21 of the pair of first terminals 2 are arranged at a predetermined interval in the Y direction.

A portion of the first terminal 2 buried in the first tower core 51 is referred to as a first tower terminal portion 22. The first tower terminal portion 22 on the Y1 side among the 2 first tower terminal portions 22 is formed straight in the Z direction so as to pass between the second concave portion 514b and the third and fourth concave portions 514c and 514d in the Y direction.

As shown in fig. 12, the first tower terminal 22 on the Y2 side among the 2 first tower terminals 22 has a crank shape bent in the plane direction orthogonal to the Y direction. That is, the first tower terminal 22 on the Y2 side includes: a first top tower terminal 221 formed from the first protruding terminal portion 21 to the Z2 side; a first intermediate turret terminal 222 extending from the first top turret terminal 221 toward the X1 side; and a first base-end turret terminal 223 extending from the X1-side end of the first intermediate turret terminal 222 toward the Z2 side.

As shown in fig. 11 and 12, the first distal turret terminal 221 is formed at a position overlapping the coupling groove portion 512b in the Z direction. The first distal-end tower terminal 221 is formed from the first protruding terminal portion 21 to a position slightly closer to the Z2 side than the coupling groove portion 512b in the Z direction. As shown in fig. 12, the first intermediate turret terminal 222 is formed on the X1 side with respect to the turret groove 512. The first base-end turret terminal 223 is formed straight in the Z direction at a position on the X1 side of the turret groove 512. In this way, at least one of the first terminals 2 is formed in a crank shape so as to avoid the stepped groove 512.

[ second core 6 ]

As shown in fig. 8, 9, and 13, the second core 6 holds the second terminals 3 so that 6 second terminals 3 are arranged in parallel. The second terminals 3 are arranged at predetermined intervals, which are maintained by the second cores 6.

The second core 6 has: a second pedestal core portion 62 formed in a plane direction parallel to the circuit substrate 12; and a second tower core 61 protruding from the second base core 62 to the Z1 side. As shown in fig. 7 to 9, the second core 6 is assembled to the first core 5 such that the second tower core portion 61 overlaps the X2 side of the first tower core portion 51 and a part of the second base core portion 62 overlaps the Z2 side of the first base core portion 52.

As shown in fig. 13, the second tower core 61 has a thickness in the X direction. The X1-side surface of the second tower core portion 61 constitutes a second overlapping surface 611 that overlaps with the first overlapping surface 511 of the first tower core portion 51 of the first core 5.

The second overlapping surface 611 is formed in a planar shape orthogonal to the X direction. The region in which the turret groove 512 of the first core 5 is projected onto the second overlapping surface 611 in the X direction is formed in a planar shape orthogonal to the X direction. In a state where the first core 5 and the second core 6 are overlapped, the second overlapped surface 611 closes the tower groove 512 from the X2 side, and a part of the air passage 14 is formed between the tower groove 512 and the second overlapped surface 611.

As shown in fig. 13, a plurality of ridges (a first ridge 612a, a second ridge 612b, a third ridge 612c, and a fourth ridge 612d) are formed on the second overlapping surface 611. As shown in fig. 4 and 5, the convex portions are formed so as to protrude from the second overlapping surface 611 toward the side where the first core 5 is disposed (the X1 side).

The convex portions are formed in regions where the concave portions of the first core 5 are projected onto the second overlapping surface 611 in the X direction. In a state where the first core 5 and the second core 6 are superposed on each other, the first ridge 612a is fitted into the first groove 514a, the second ridge 612b is fitted into the second groove 514b, the third ridge 612c is fitted into the third groove 514c, and the fourth ridge 612d is fitted into the fourth groove 514 d.

As shown in fig. 4, the portion where the ridge portion and the recessed portion are fitted is referred to as a fitting portion 15. Further, on the Y1 side of the tower groove 512, there are provided an outer fitting portion 15a as a portion along the outer groove portion 512a in the fitting portion 15, and an inner fitting portion 15b as a portion along the inner groove portion 512c in the fitting portion 15. The outer fitting portion 15a is formed by a part of the third ridge 612c and a part of the third groove 514c, and the inner fitting portion 15b is formed by a part of the second ridge 612b and a part of the second groove 514 b. Here, as described above, the inner groove 512c is disposed at a position offset to the Y2 side with respect to the outer groove 512 a. The inner fitting portion 15b is disposed at a position offset to the Y2 side with respect to the outer fitting portion 15 a. This makes it easy to bring both the inner fitting portion 15b and the outer fitting portion 15a close to the bent tower groove 512.

The convex strip portion has a shape substantially equal to the concave strip portion to be fitted in a cross section orthogonal to the Z direction. That is, the ridges fit into the valleys. Further, the present invention is not limited to this, and for example, a configuration may be adopted in which the ridge portions are slightly larger than the recessed portions in the cross section orthogonal to the Z direction and the ridge portions are press-fitted into the recessed portions, and the ridge portions may be slightly smaller than the recessed portions. The second pedestal core 62 is formed from the Z2-side end of the second tower core 61 toward the X1 side.

The second base core 62 is formed in a planar shape orthogonal to the Z direction. The second pedestal core 62 is formed from the second tower core 61 toward the X1 side, and protrudes further toward the Y1 side than the second tower core 61. The end of the second terminal 3 on the side connected to the circuit board 12 protrudes from the Y1-side end of the first base-type core 52 toward the Z2 side.

[ second terminal 3 ]

As shown in fig. 13 and 14, the second projecting terminal portions 31, which are the end portions of the 6 second terminals 3, project from the end portion on the Z1 side of the second tower-shaped core portion 61 toward the Z1 side. The second protruding terminal portions 31 of the 6 second terminals 3 are arranged at equal intervals in the Y direction.

A portion of the 6 second terminals 3 embedded in the second tower core 61 is referred to as a second tower terminal portion 32. The center portion of each second tower terminal 32 in the Z direction is bent, and the second tower terminal 32 is formed in a crank shape as a whole. That is, the second tower terminal portion 32 has: a second top-end tower terminal 321 formed from the second projecting terminal portion 31 to the Z2 side; a second intermediate turret terminal 322 formed by bending in the Y direction from the second tip turret terminal 321; and a second base-end turret terminal 323 extending from an end of the second intermediate turret terminal 322 opposite to the second tip turret terminal 321 toward the Z2.

The 6 second tip turret terminals 321 are each formed straight in the Z direction. The 6 second top turret terminals 321 are arranged at equal intervals in the Y direction.

Of the 6 second intermediate turret terminals 322, 5 except the second intermediate turret terminal 322 at the end of the Y2 side are inclined so as to extend from the second tip turret terminal 321 toward the Z1 side and the Y1 side. On the other hand, the second intermediate turret terminal 322 arranged at the Y2 side end among the 6 second intermediate turret terminals 322 is inclined so as to be located closer to the Y2 side than the second tip turret terminal 321 is to the Z1 side. That is, of the 6 second intermediate turret terminals 322, the second intermediate turret terminal 322 disposed at the end of the Y2 side is inclined so as to be farther away from the adjacent second intermediate turret terminal 322 toward the Z1 side.

The second base-end turret terminal 323 is formed along the Z direction from the second intermediate turret terminal 322 toward the Z2 side. The Y-direction interval between the second base tower terminal 323 arranged at the end of the Y2 side among the 6 second base tower terminals 323 and the adjacent second base tower terminal 323 is wider than the interval between the other second base tower terminals 323.

Here, in fig. 14, the outline of the tower groove 512 when viewed from the X direction is indicated by a two-dot chain line. As shown in fig. 14, the inner slot portion 512c of the turret slot 512 is located in the Y direction in a region between the second base-end turret terminal 323 at the end on the Y2 side and the second base-end turret terminal 323 adjacent thereto.

As shown in fig. 13, the second base terminal portions 33 are provided from the Z2-side end portions of the 6 second tower terminal portions 32 toward the X1 side. The second base terminal portion 33 is a portion buried in the second base core portion 62 of the second core 6. Further, a part of the surface of the portion of the second terminal 3 embedded in the second pedestal core portion 62 is exposed from the second pedestal core portion 62.

As shown in fig. 4, 9, and 13, the 6 second base terminal portions 33 include 6 second specific terminal portions 331, and the 6 second specific terminal portions 331 are formed so as to be aligned in the Y direction and formed in the X direction from the second tower terminal portions 32 toward the X1 side.

The 6 second specific terminal portions 331 include second isolated terminals 331a arranged at the end on the Y2 side and second equidistant terminal groups 331b each including 5 second specific terminal portions 331 arranged at equal intervals in the Y direction. The interval between the second specific terminal portions 331 of the second isolated terminal 331a and the second equidistant terminal group 331b arranged closest to the second isolated terminal 331a in the Y direction is larger than the interval between the second specific terminal portions 331 of the second equidistant terminal group 331b adjacent to each other in the Y direction.

Also, a second hole 621 is formed in a second base core portion 62 of the second core 6 at a location between the second isolated terminal 331a and the second equally spaced terminal group 331b in the Y direction. That is, the second hole portion 621 is formed in the second seat core portion 62 so as to avoid the second terminal 3.

The second hole 621 is formed so as to penetrate the second base core 62 in the Z direction. As shown in fig. 4, the second hole portion 621 is formed such that: in a state where the first core 5 and the second core 6 are superposed on each other, the opening portion on the Z2 side of the inner groove portion 512c of the tower groove 512 overlaps in the Z direction and communicates with the inner groove portion 512 c. The size of the second hole 621 as viewed in the Z direction is equal to the size of the open portion on the Z2 side of the inner groove 512 c.

As shown in fig. 4, in a state where the first core 5 and the second core 6 are overlapped, the outer groove portion 512a of the turret groove 512 is formed at a position overlapping the second equally-spaced terminal group 331b in the Z direction. Therefore, the second hole 621 cannot be formed in the portion of the second pedestal core portion 62 that overlaps the outer groove portion 512a in the Z direction. Accordingly, in the present embodiment, the tower groove 512 is formed in a crank shape so that the tower groove 512 can communicate with the second hole 621 formed at a position offset in the Y direction from the outer groove portion 512 a.

[ third core 7 ]

As shown in fig. 7 to 9, the third core 7 holds the third terminals 4 such that 6 third terminals 4 are arranged in parallel. The third terminals 4 are arranged at a predetermined interval, which is maintained by the third core 7.

As shown in fig. 8 and 9, the third core 7 includes a third base core portion 72 formed in a plane direction parallel to the circuit board 12, and a third tower core portion 71 protruding from the third base core portion 72 to the Z1 side. The third core 7 is assembled to the second core 6 such that the third tower core portion 71 overlaps the X2 side of the second tower core portion 61 and a part of the third base core portion 72 overlaps the Z2 side of the second base core portion 62.

The third tower core 71 has a thickness in the X direction orthogonal to the Z direction. The surface of the third tower core 71 on the X1 side overlaps the surface of the second tower core 61 of the second core 6 on the X2 side in the X direction. The X1-side surface of the third tower core 71 and the X2-side surface of the second tower core 61 are formed in planar shapes orthogonal to the X direction.

As shown in fig. 8, a positioning protrusion 613 protruding toward the X2 side is formed on the X2 side surface of the second tower core portion 61, and a positioning recess (not shown) into which the positioning protrusion 613 engages is formed on the X1 side surface of the third tower core portion 71. In a state where the second core 6 and the third core 7 are overlapped, the positioning protrusion 613 is inserted and fitted into the positioning recess, and thereby, displacement in a direction orthogonal to the X direction between the second core 6 and the third core 7 can be prevented. The third pedestal core portion 72 is formed from the Z2-side end of the third tower core portion 71 toward the X1 side.

The third base core portion 72 is formed in a planar shape orthogonal to the Z direction. The third pedestal core portion 72 is formed from the third tower core portion 71 toward the X1 side, and protrudes further toward the Y1 side than the third tower core portion 71. The end of the third terminal 4 on the side connected to the circuit board 12 protrudes from the Y1-side end of the third base-type core portion 72 toward the Z2 side.

[ third terminal 4 ]

As shown in fig. 7 to 9, the third protruding terminal portions 41, which are the end portions of the 6 third terminals 4, protrude from the end portion on the Z1 side of the third tower-shaped core portion 71 toward the Z1 side. The 6 third protruding terminal portions 41 are arranged at equal intervals in the Y direction.

The portion of the 6 third terminals 4 embedded in the third tower core 71 has the same shape and structure as the second tower terminal portion 32. As shown in fig. 4, the third terminal 4 includes 6 third specific terminal portions 42, and the 6 third specific terminal portions 42 are formed so as to be aligned in the Y direction and to extend in the X1 direction from the end of the third terminal 4 on the Z2 side where the third tower core portion 71 is embedded. The 6 third specific terminal portions 42 have the same configuration as the 6 second specific terminal portions 331.

That is, the 6 third specific terminal portions 42 include the third isolated terminals 421 disposed at the end of the Y2 side and the third equally spaced terminal group 422 including the 5 third specific terminal portions 42 disposed equally spaced in the Y direction. The distance between the third specific terminal portions 42 arranged closest to the third isolated terminal 421 in the third isolated terminal 421 and the third equidistant terminal group 422 in the Y direction is larger than the distance between the mutually adjacent third specific terminal portions 42 in the third equidistant terminal group 422 in the Y direction.

Further, a third hole 721 is formed in the third base core portion 72 of the third core 7 at a portion between the third isolated terminal 421 and the third equally spaced terminal group 422. That is, the third hole portion 721 is formed in the third pedestal core portion 72 so as to avoid the third terminal 4.

The third hole portion 721 is formed so as to penetrate the third pedestal core portion 72 in the Z direction. The third hole portion 721 is formed: the first core 5, the second core 6, and the third core 7 overlap each other in the Z direction with the open portion on the Z2 side of the inner groove 512c of the tower groove 512 and the second hole 621 of the second core 6, and communicate with the inner groove 512c and the second hole 621. The size of the third hole 721 as viewed in the Z direction is equal to the size of the opening on the Z2 side of the inner slot 512 c.

The first core 5, the second core 6, and the third core 7 are each formed by insert molding as follows: terminals are arranged in an aligned state in a mold for molding the first core 5, the second core 6, and the third core 7, and a resin material is injected into the mold. As shown in fig. 3, a housing 8 is formed so as to cover the first core 5, the second core 6, and the third core 7.

[ case 8 ]

The housing 8 is molded by insert molding in which a first core 5 holding the first terminal 2, a second core 6 holding the second terminal 3, and a third core 7 holding the third terminal 4 are formed as inserts.

As shown in fig. 3, the housing 8 includes: a housing tower 81 formed to be elongated in the Z direction so as to cover the peripheries of the first tower core 51 of the first core 5, the second tower core 61 of the second core 6, and the third tower core 71 of the third core 7; and a case base portion 82 formed in a planar shape orthogonal to the Z direction from the vicinity of the end portion on the Z2 side of the case tower portion 81.

As shown in fig. 1 to 3, the case tower 81 includes a mounting portion 811 at an end on the Z1 side. As shown in fig. 1 and 3, the mounting portion 811 surrounds one end of each of the first terminal 2, the second terminal 3, and the third terminal 4, and the mating connector 191 is mounted inside. The mounting portion 811 has a cylindrical shape formed in the Z direction.

A partition wall 812 is formed in the housing 8, and the partition wall 812 ensures electrical insulation between the terminals exposed in the mounting portion 811. The partition 812 is formed to protrude toward the Z1 side between the pair of first terminals 2 and between the first terminal 2 and the second terminal 3. The Z2 side of the mounting portion 811 is closed by a portion of the housing 8, the first core 5, the second core 6, and the third core 7.

As shown in fig. 2, the housing opening 810 is formed in a portion near the Z2 side of the mounting portion 811 on the side surface of the housing tower 81. As described above, the housing opening 810 is an opening that opens the through-hole 513 of the first core 5 to the atmosphere. As shown in fig. 6, the housing opening 810 and the through-hole 513 are formed continuously in a straight line in the X direction. The tower groove 512 does not directly communicate with the space inside the mounting portion 811.

As shown in fig. 2 and 6, a gas permeable membrane 16 covering the case opening 810 from the X1 side is disposed on the side surface of the case tower 81. The gas permeable membrane 16 is a filter that inhibits the passage of liquids and solids and allows the passage of gases. The air-permeable membrane 16 can be composed of a porous membrane formed of, for example, fluororesin or polyolefin. The ventilation film 16 is circular, but is not limited thereto.

As shown in fig. 2 and 3, the side surface of the case tower 81 has a seal arrangement recess 813 on the Z2 side of the case opening 810. The seal disposition recess 813 has a shape that is recessed toward the inner peripheral side over the entire circumference. An annular seal portion 17 is fitted in the seal arrangement recess 813.

As shown in fig. 3, the sealing portion 17 seals between the connector 1 and, for example, a mating case 192 to which a mating connector 191 is attached. That is, the housing tower 81 is inserted into the mating arrangement hole 193 formed in the mating housing 192, and the sealing portion 17 seals between the connector 1 and the mating arrangement hole 193 of the mating housing 192.

The Z2-side end of the casing tower 81 and the casing base 82 penetrate the wall of the first casing section 111 and are in close contact with the wall.

[ case 11 ]

As shown in fig. 2 and 3, case 11 forming internal space 13 together with connector 1 is configured by fastening 2 members (first case portion 111, second case portion 112) divided into two in the Z direction with bolts (not shown). The first tank portion 111 is formed by insert molding as follows: the connector 1 is disposed in a mold for molding the first housing portion 111, and a resin material constituting the first housing portion 111 is injected into the mold. Thus, the case 8 is formed to be in close contact with the first casing section 111.

As shown in fig. 3, the housing 8 has an engagement recess 821 recessed toward the inner periphery side in a close contact portion with the first casing portion 111. The first casing portion 111 also enters the engagement recess 821. This improves the adhesion strength between the case 8 and the first casing section 111. The circuit substrate 12 is fastened to a boss portion 111a provided to the first case portion 111 with a bolt B.

Here, the control device 10 provided with the connector 1 is disposed in oil filled in the automatic transmission. As shown in fig. 3, in a state where the mating connector 191 and the mating case 192 are assembled, the region of the control device 10 on the Z2 side with respect to the seal 17 is disposed in an oil environment, and the region of the control device 10 on the Z1 side with respect to the seal 17 is disposed in the internal space 13 of the mating case 192. Accordingly, the case opening 810 disposed between the mounting portion 811 and the sealing portion 17 in the Z direction is disposed in the internal space 13 of the counter case 192.

The internal space 13 of the partner case 192 communicates with the atmosphere. Thus, in a state where the control device 10 including the connector 1 is mounted on the vehicle, the air passage 14 communicates with the atmosphere from the housing opening 810 via the counterpart case 192. Further, the control device 10 is configured to: in a state where the air passage 14 is closed, the internal space 13 of the case 11 is a sealed space.

[ effect ] of action

Next, the operation and effects of the present embodiment will be described.

In the connector 1 of the present embodiment, the tower groove 512 has a curved shape in the overlapping plane. Therefore, even if the turret groove 512 interferes with the first terminal 2 formed on the first core 5, the second terminal 3 formed on the second core 6, and the like when the turret groove 512 is formed linearly, the turret groove 512 can be prevented from interfering with the first terminal 2, the second terminal, and the like.

Further, the tower tank 512 includes: an outer groove 512a elongated in the Z direction; and an inner groove 512c formed to be elongated in the protruding direction at a position offset in the Y direction with respect to the outer groove 512a, and formed closer to the internal space 13 of the air passage 14 than the outer groove 512 a. Therefore, even when, for example, a terminal or another obstacle is disposed in the first core 5 or the second core 6 on the extension line of the outer groove 512a in the Z direction, the inner groove 512c is offset in the Y direction with respect to the outer groove 512a, and the air passage 14 can be formed by getting away the obstacle.

The second base terminal portion 33 is disposed on an extension line extending the outer groove portion 512a of the turret groove 512 in the Z direction. Therefore, if the groove portion 512 is formed so that the outer groove portion 512a extends in the Z direction as it is, the air passage 14 may be blocked by the second chassis terminal portion 33 or the air passage 14 may not be formed due to interference of the second chassis terminal portion 33. Therefore, the second chassis core 62 has a second hole portion 621, and the second hole portion 621 is formed at a position shifted from the second chassis terminal portion 33 in the plane direction, and constitutes a part of the air passage 14. The inner groove 512c of the tower groove 512 communicates with the second hole 621. Therefore, even if the second chassis terminal portion 33 is located on the extension line extending the outer groove portion 512a in the Z direction, the groove portion 512 and the second hole portion 621 can be formed so as to avoid the second chassis terminal portion 33.

In addition, the second pedestal core 62 has a second hole portion 621 between the second pedestal terminal portions 33. Therefore, the space between the second base terminal portions 33 in the second base core portion 62 can be effectively used as the air passage 14, and therefore, the size of the entire connector 1 can be easily prevented from becoming large.

The second overlapping surface 611 of the second core 6 has a ridge portion formed along the groove portion 512 on both sides of the formation portion of the groove portion 512, and the first overlapping surface 511 of the first core 5 has a recessed portion fitted with the ridge portion. Therefore, the shape of the contact surface between the ridge portion and the groove portion can be made complicated. Therefore, the following can be easily prevented: when the liquid resin constituting the housing 8 is injected into the mold in a state where the first core 5 and the second core 6 are disposed in the molding mold for the housing 8 at the time of molding the housing 8, the liquid resin blocks the air passage 14 through the interface between the first core 5 and the second core 6.

Further, the inner fitting portion 15b, which is a portion along the inner groove portion 512c in the fitting portion 15 in which the convex strip portion and the concave strip portion are fitted, is offset to the same side (Y2 side) as the side in which the inner groove portion 512c is offset to the outer groove portion 512a with respect to the outer fitting portion 15a, which is a portion along the outer groove portion 512a in the fitting portion 15. Therefore, both the inner fitting portion 15b and the outer fitting portion 15a can easily approach the tower groove 512. Therefore, even when the liquid resin constituting the housing 8 enters the interface between the first core 5 and the second core 6 at the time of molding the housing 8, the liquid resin can be prevented from entering the vicinity of the groove portion 512. Therefore, it is easy to further prevent the liquid resin from blocking the air passage 14 by the interface between the first core 5 and the second core 6.

As described above, according to the present embodiment, it is possible to provide a connector in which the groove portion is easily and appropriately formed.

(embodiment mode 2)

As shown in fig. 15 to 17, the present embodiment is an embodiment in which a part of the ventilation path 14 is modified with respect to embodiment 1.

As shown in fig. 15 and 16, the tower groove 512 has an extension groove 512d extending from the end of the outer groove 512a at the Z1 side toward the Y2 side. The end of the extension groove 512d on the side opposite to the outer groove 512a (i.e., the end on the Y2 side) is open to the Y2 side.

As shown in fig. 17, the second overlapping surface 611 of the second tower core portion 61 of the second core 6 is formed in a planar shape orthogonal to the X direction as a whole. As shown in fig. 15, in a state where the first core 5 and the second core 6 are overlapped, a part of the air passage 14 is formed between the tower groove 512 including the extended groove portion 512d and the second overlapped surface 611.

As shown in fig. 15, the case opening 810 is formed on the Y2 side of the extension groove 512d so as to communicate with the Y2-side end of the extension groove 512 d.

In the present embodiment, the first core 5 does not have the through-hole shown in embodiment 1 (see reference numeral 513 in fig. 4, 6, and the like). In the present embodiment, the first overlapping surface 511 and the second overlapping surface 611 do not have the ridges and the grooves described in embodiment 1.

The rest is the same as embodiment 1.

Note that, of the reference numerals used later in embodiment 2, those that are the same as those used in the present embodiment denote the same components and the like as those in the present embodiment unless otherwise noted.

In the present embodiment, in order to form the ventilation passage 14, only the groove portion 512 may be formed in the first core 5. Therefore, the shape of the first core 5 is easily simplified.

The other components have the same operational effects as those of embodiment 1.

(embodiment mode 3)

In the present embodiment, as shown in fig. 18, a portion corresponding to the first casing section (see reference numeral 111 in fig. 1 to 3, etc.) described in embodiment 1 is configured by the case 8.

In the present embodiment, the connector 1 forms the internal space 13 for accommodating the circuit board 12 together with the second housing portion 112 as the housing 11.

The rest is the same as embodiment 1.

In the present embodiment, since a part of the housing 8 functions as a case, the number of components can be easily reduced.

The other components have the same operational effects as those of embodiment 1.

The present invention is not limited to the above embodiments, and can be applied to various embodiments without departing from the scope of the invention.
