Background

Conventionally, as a connector system including a harness connector connectable to an interface of a unit, a connector system described in japanese patent application laid-open No. 2016-. The wire harness connector has a 1 st fixing member and a 2 nd fixing member. The 2 nd fixing member directly fixes the wire and the harness connector to the unit without a margin, in addition to the original connector locking by the 1 st fixing member. Thereby, the interface and the harness connector have the same vibration level, so that wear of the electrical contact elements of the connector system is suppressed to a minimum.

Disclosure of Invention

Problems to be solved by the invention

However, in the above-described connector system, the lock member for fixing the 2 nd fixing member is provided in the unit, and it is not true that the design change of the unit is not performed, and therefore, it is not easy to perform a countermeasure. Therefore, it can be said that it is most desirable to perform the vibration countermeasure only by the design change of the harness connector without accompanying the design change of the unit.

Means for solving the problems

The lever type connector disclosed in the present specification includes: a terminal block having a fitting portion and provided with a 1 st pin and a 2 nd pin, the 1 st pin and the 2 nd pin protruding from an outer periphery of the fitting portion in an orthogonal arrangement; a housing having a cover portion in which the fitting portion can be fitted; a 1 st lever attached to the housing, the 1 st lever engaging with the 1 st pin to fit or release the fitting portion into or from the cover portion; and a 2 nd rod attached to the cover portion, the 2 nd rod being movable between a locking position where the 2 nd rod is locked to the 2 nd pin and a non-locking position where the 2 nd rod is not locked to the 2 nd pin, the 2 nd pin being configured to include a 2 nd shaft portion and a 2 nd flange portion, the 2 nd shaft portion being connected to an outer periphery of the fitting portion, the 2 nd flange portion being located at a tip end of the 2 nd shaft portion and having a larger diameter than the 2 nd shaft portion, and the 2 nd rod being locked to the 2 nd flange portion at both front and rear sides of the fitting portion in a fitting direction with the 2 nd shaft portion as a center in the locking position.

According to this configuration, when the fitting portion is fitted into the cover portion shallowly, the 1 st lever is moved to engage with the 1 st pin, thereby performing fitting. When the 2 nd rod is moved from the non-locking position to the locking position after the fitting between the cover portion and the fitting portion is completed, the 2 nd flange portion abuts against the 2 nd rod on both front and rear sides of the 2 nd shaft portion.

Here, when the housing is about to move in the left-right direction, the 1 st lever engages with the 1 st pin, so that the movement of the housing in the left-right direction is suppressed. Further, when the housing is to be moved in the up-down direction, the 2 nd lever is locked to the 2 nd flange portion of the 2 nd pin, so that the up-down movement of the housing is suppressed. Therefore, the operation of the housing can be suppressed in both the left-right direction and the up-down direction, and the vibration countermeasure can be taken only by the design change of the housing and the terminal block without accompanying the design change of the device side to which the terminal block is attached.

The lever type connector disclosed in the present specification may have the following configuration.

The fitting portion of the terminal block may have a substantially rectangular shape that is laterally long in a front view, and the pair of 2 nd pins may be provided so as to be aligned in a lateral direction at a long side portion extending in the lateral direction in an outer periphery of the fitting portion.

According to this configuration, since the pair of 2 nd pins are provided so as to be aligned in the lateral direction, it is possible to further suppress vibration of the housing in the vertical direction, and also to suppress vibration in the rotational direction when the housing is to be moved in the rotational direction about the axis extending in the fitting direction.

The structure may be such that a pair of the 2 nd pins is provided in one of the long side portions so as to be aligned in the lateral direction, and a pair of the 2 nd pins is provided in the other of the long side portions so as to be aligned in the lateral direction.

With this configuration, since the vibration of the housing can be suppressed by each of the pair of long side portions, the vibration can be suppressed more easily than in the case of using one of the long side portions.

The 2 nd rod may have a groove into which the 2 nd shaft portion is inserted, the groove including a vertical groove extending in the fitting direction of the fitting portion and a horizontal groove provided in an orthogonal arrangement to the vertical groove.

According to this configuration, when the fitting portion is fitted into the cover portion, the 2 nd shaft portion travels in the vertical groove, and when the 2 nd rod is moved from the non-locking position to the locking position after fitting, the 2 nd shaft portion travels in the horizontal groove. Therefore, both side portions of the lateral groove are locked to the 2 nd flange portion.

Effects of the invention

According to the lever-type connector disclosed in the present specification, it is possible to implement a countermeasure against vibration only by a design change of the housing and the terminal block without accompanying a design change of a device side to which the terminal block is attached.

Detailed Description

< embodiment >

The embodiment is described with reference to the drawings of fig. 1 to 18. As shown in fig. 1, the lever-type connector 10 of the present embodiment includes a terminal block 20, a housing 30, a 1 st lever 40, and a 2 nd lever 50. The 1 st lever 40 is rotatably attached to the housing 30 and is movable between an initial position shown in fig. 1 and a fitting position shown in fig. 2. The 2 nd lever 50 is slidably attached to the housing 30 and is movable between a non-locking position shown in fig. 2 and a locking position shown in fig. 3.

The terminal block 20 includes a mounting plate 21 mounted on a device not shown, a fitting portion 22 provided to project forward from the mounting plate 21, a pair of male terminals 23 held in the fitting portion 22, and the like. As shown in fig. 17, the fitting portion 22 has a horizontally long rectangular shape in front view. The upper surface portion 24 and the lower surface portion 25 of the fitting portion 22 are longer than the two side surface portions 26. In addition, the male terminal 23 is formed in a flat tab shape.

In each case one 1 st pin 27 is arranged on each of the two side parts 26. Each of the 1 st pins 27 protrudes laterally in the opposite direction. In addition, a pair of left and right 2 nd pins 28 are provided in the upper surface portion 24 so as to project upward in a lateral direction, and a pair of left and right 2 nd pins 28 are provided in the lower surface portion 25 so as to project downward in a lateral direction. The upper pair of left and right 2 nd pins 28 and the lower pair of left and right 2 nd pins 28 are arranged in vertical alignment. The pair of 1 st pins 27 and the four 2 nd pins 28 are arranged in a circumferential direction.

The 1 st pin 27 includes: a 1 st shaft portion 27A coupled to the side surface portion 26; and a 1 st flange portion 27B located at the tip of the 1 st shaft portion 27A, having a diameter larger than that of the 1 st shaft portion 27A, and disposed coaxially with the 1 st shaft portion 27A. Similarly, the 2 nd pin 28 is configured to include: a 2 nd shaft portion 28A coupled to the upper surface portion 24 or the lower surface portion 25; and a 2 nd flange portion 28B located at the tip of the 2 nd shaft portion 28A, having a larger diameter than the 2 nd shaft portion 28A, and disposed coaxially with the 2 nd shaft portion 28A.

The housing 30 is made of synthetic resin and has a cover 31 as shown in fig. 1, and the fitting portion 22 is fitted into the cover 31. The cover 31 is open at the front, a pair of female terminals 32 and a pair of terminal holding portions 33 are provided inside the cover 31, and the female terminals 32 are held inside the pair of terminal holding portions 33. When fitting portion 22 is fitted into hood 31, a pair of male terminals 23 and a pair of female terminals 32 are conductively connected. As shown in fig. 12, the female terminal 32 includes a terminal connection portion 32A connected to the male terminal 23 and a wire connection portion 32B connected to the end of the wire 60. The electric wire 60 is drawn out rearward from the housing 30.

A rubber plug housing 34 is provided behind the cover 31 in the housing 30, and a rubber plug 70 is housed together with the electric wire 60 in the rubber plug housing 34. The rubber stopper 70 is accommodated in the rear end of the rubber stopper accommodating portion 34 and is prevented from coming off by the rear stopper 71. The rubber plug 70 is in close contact with both the outer peripheral surface of the electric wire 60 and the inner peripheral surface of the rubber plug housing portion 34, and prevents water from entering the rubber plug housing portion 34 from behind.

On both side surfaces of the cover 31, a pair of lever shaft portions 35 are provided so as to project in opposite directions to each other. On the other hand, as shown in fig. 1, the 1 st lever 40 includes a pair of cam plates 41 and an operation portion 42 connecting the cam plates 41. The cam plate 41 is provided with a shaft hole 43, and the lever shaft portion 35 is inserted into the shaft hole 43. Thereby, the 1 st lever 40 can rotate about the pair of lever shaft portions 35.

The cam plate 41 is formed with a cam groove 44. As shown in fig. 1, when the 1 st lever 40 is at the initial position, the inlet of the cam groove 44 assumes a posture of opening forward, and therefore, when the fitting portion 22 is fitted into the cover portion 31 shallowly, the 1 st pin 27 enters the inlet of the cam groove 44. When the 1 st lever 40 is then rotated to move from the initial position to the fitting position, the 1 st pin 27 engages with the inner wall of the cam groove 44 to perform a cam action, and the fitting portion 22 is fitted to the cover 31. When the 1 st lever 40 reaches the fitting position, as shown in fig. 2, the fitting of the fitting portion 22 and the hood 31 is completed. On the contrary, when the 1 st lever 40 is rotated from the fitting position to the initial position, the fitting portion 22 and the cover 31 are separated, and the fitting portion 22 and the cover 31 are manually separated from each other at the initial position, whereby the separation of the fitting portion 22 and the cover 31 is completed.

As shown in fig. 6, a pair of fitting position locking portions 45 is provided on both sides of the operation portion 42 of the 1 st lever 40, and a pair of initial position locking portions 46 is provided on both sides of the cam plate 41. The 1 st lever 40 is held at the initial position by the locking of the initial position locking portion 46 with a projection provided on the side portion of the hood 31. As shown in fig. 13, the fitting position locking portion 45 is locked to a projection provided on a side portion of the rubber plug housing portion 34, and the 1 st lever 40 is held at the fitting position.

As shown in fig. 1, an insertion groove 36 through which the 2 nd pin 28 is inserted is provided at the front edge of the cover 31. Insertion groove 36 is formed to extend straight rearward from the front edge of cover 31. The insertion grooves 36 are provided in pairs on both upper and lower sides of the cover 31 so as to be disposed corresponding to the positions of the 2 nd pins 28 in the non-locking position.

As shown in fig. 4 and 5, a pair of 2 nd rods 50 are attached to both upper and lower sides of the cover 31. The 2 nd rod 50 is a horizontally long rectangle in a plan view, and is slidable in a direction orthogonal to the fitting direction of the fitting portion 22 and the cover 31. As shown in fig. 7, the sliding structure is composed of a guide concave portion 37 and a guide convex portion 51, the guide concave portion 37 is provided to protrude in a dovetail groove shape from the outer periphery of the cover portion 31, and the guide convex portion 51 is provided to protrude from the 2 nd rod 50. By the guide convex 51 moving along the guide concave 37, the 2 nd rod 50 moves in parallel along the outer periphery of the hood 31 without departing from the hood 31.

As shown in fig. 4, the 2 nd rod 50 has an L-shaped groove formed by the vertical groove 52 and the horizontal groove 53, the vertical groove 52 matches the insertion groove 36 of the cover portion 31 in the non-locking position, therefore, when the fitting portion 22 is fitted into the cover portion 31, the 2 nd shaft portion 28A advances from the entrance of the vertical groove 52 toward the bottom end, when the fitting is completed, the 2 nd shaft portion 28A reaches the bottom end of the vertical groove 52, when the 2 nd rod 50 is moved from the non-locking position to the locking position after the fitting of the fitting portion 22 and the cover portion 31 is completed, as shown in fig. 10, the 2 nd shaft portion 28A advances from the entrance of the horizontal groove 53 toward the bottom end, and when the 2 nd rod 50 reaches the locking position, the 2 nd shaft portion 28A reaches the bottom end of the horizontal groove 53, at this time, the insertion groove 36 and the vertical groove 52 are arranged so as not to overlap each other in a plan view, and therefore, the 2 nd pin 28 does not move forward of the cover portion 31 through.

Then, in the lever type connector 10 of the present embodiment, measures against vibrations in various directions are taken by both the 1 st lever 40 and the 2 nd lever 50.

First, a countermeasure against vibration in the left-right direction will be described, where the left-right direction refers to the vertical direction shown in fig. 10 by arrow lines L, R, and L refers to the left, and R refers to the right, and when the electric wire 60 vibrates in the left-right direction, the case 30 will move in the left-right direction in accordance with this, however, as shown in fig. 14, the 1 st pin 27 is engaged with the cam groove 44, and movement in the left-right direction is suppressed, and when the electric wire 60 vibrates in the left-right direction L, the front bottom wall 44F and the 1 st flange 27B of the pair of bottom walls 44F, 44R and the 1 st flange 27B located on the front and rear sides of the 1 st shaft 27A among the inner walls of the cam groove 44 are engaged with each other, and when the electric wire 60 vibrates in the left-right direction, the movement of the case 30 in the left-right direction L is suppressed, and when the electric wire 60 vibrates in the right-right direction, the rear bottom wall 44R and the rear bottom wall 27R and the flange 27B of the left side are engaged with the first flange 27B, and the left-side flange 27B, and the case 30 is locked with the left-side bottom wall 27B of the first pin 27B, and the rear flange 27B of the left-right-side of the case 30 is suppressed.

Next, a countermeasure against vibration in the vertical direction will be described. Here, the vertical direction is the vertical direction indicated by an arrow line U, D in fig. 12, U is the upper direction, and D is the lower direction. When the electric wire 60 vibrates in the up-down direction, the 2 nd lever 50 is locked to the 2 nd pin 28, and the movement in the up-down direction is suppressed. That is, the front wall 50F of the 2 nd lever 50 located on the front side of the 2 nd shaft portion 28A, the rear wall 50R located on the rear side of the 2 nd shaft portion 28A, and the 2 nd flange portion 28B are locked to each other, and thereby the movement in the vertical direction is suppressed. When the electric wire 60 vibrates upward U, the rear wall 50R is locked to the 2 nd flange portion 28B at the 2 nd pin 28 on the upper side, and the front wall 50F is locked to the 2 nd flange portion 28B at the 2 nd pin 28 on the lower side, whereby the upward U movement of the case 30 is suppressed. On the contrary, when the electric wire 60 vibrates downward D, the front wall 50F is locked to the 2 nd flange portion 28B at the upper 2 nd pin 28, and the rear wall 50R is locked to the 2 nd flange portion 28B at the lower 2 nd pin 28, whereby the downward D movement of the case 30 is suppressed.

Next, countermeasures against vibration in the rotational direction about an axis P (see fig. 10 and 11) extending in the fitting direction will be described. Here, the axis P is an axis extending in the fitting direction at the center position of the pair of electric wires 60. The rotation direction is indicated by arrow lines R1 and R2 in fig. 11, R1 is clockwise, and R2 is counterclockwise. When the electric wire 60 vibrates in the clockwise direction R1, the 2 nd lever 50 is locked to the 2 nd flange portion 28B at the 2 nd pin 28 on the upper left and lower right, and the movement of the case 30 in the clockwise direction R1 is suppressed. On the contrary, when the electric wire 60 vibrates in the counterclockwise direction R2, the 2 nd lever 50 is locked to the 2 nd flange portion 28B at the 2 nd pin 28 on the upper right and lower left, and the movement of the case 30 in the counterclockwise direction R2 is suppressed.

Thus, the housing 30 is in a state in which the movement in the left-right direction is suppressed by the 1 st lever 40 and the movement in the up-down direction and the rotational direction is suppressed by the 2 nd lever 50. Therefore, even when the lever connector 10 receives vibration as a whole, relative movement between the terminal block 20 and the housing 30 can be suppressed, and abrasion of the contact portions of the terminals 23 and 32 can be avoided.

As described above, in the present embodiment, after the fitting portion 22 is shallowly fitted into the cover portion 31, the 1 st lever 40 is moved to engage with the 1 st pin 27, thereby performing fitting. When the 2 nd rod 50 is moved from the non-locking position to the locking position after the fitting between the cover 31 and the fitting portion 22 is completed, the 2 nd flange portion 28B abuts on the 2 nd rod 50 on both front and rear sides of the 2 nd shaft portion 28A.

Here, when the housing 30 is to be moved in the left-right direction, the 1 st lever 40 engages with the 1 st pin 27, and therefore the movement of the housing 30 in the left-right direction is suppressed. Further, when the housing 30 is to be moved in the up-down direction, the 2 nd lever 50 is locked to the 2 nd flange portion 28B of the 2 nd pin 28, and therefore, the movement of the housing 30 in the up-down direction is suppressed. Therefore, the operation of the case 30 can be suppressed in both the left-right direction and the up-down direction, and the vibration can be prevented only by the design change of the case 30 and the terminal block 20 without accompanying the design change of the device side to which the terminal block 20 is attached.

The fitting portion 22 of the terminal block 20 may be configured to have a substantially rectangular shape that is laterally long in a front view, and a pair of the 2 nd pins 28 may be provided in a lateral arrangement on a long side portion (upper surface portion 24) extending in the lateral direction in the outer periphery of the fitting portion 22.

According to such a configuration, since the pair of second pins 28 are provided so as to be aligned in the lateral direction, it is possible to further suppress vibration of the housing 30 in the vertical direction, and also to suppress vibration in the rotational direction when the housing 30 is to be moved in the rotational direction about the axis P extending in the fitting direction.

The pair of 2 nd pins 28 may be provided in one of the long side portions so as to be aligned in the lateral direction, and the pair of 2 nd pins 28 may be provided in the other of the long side portions so as to be aligned in the lateral direction.

With this configuration, since the vibration of the case 30 can be suppressed by each of the pair of long side portions, the suppression is easier than that by one of the long side portions.

The 2 nd lever 50 may have a groove through which the 2 nd shaft portion 28A is inserted, and the groove may be composed of a vertical groove 52 extending in the fitting direction of the fitting portion 22 and a horizontal groove 53 provided in an arrangement orthogonal to the vertical groove 52.

According to such a configuration, when the fitting portion 22 is fitted into the cover portion 31, the 2 nd shaft portion 28A travels in the vertical groove 52, and when the 2 nd rod 50 is moved from the non-locking position to the locking position after fitting, the 2 nd shaft portion 28A travels in the horizontal groove 53. Therefore, both side portions of the lateral groove 53 are locked to the 2 nd flange portion 28B.
