Description

  The technology disclosed by this specification is related with a connector.

  As an example of a conventional connector, a connector assembly described in JP-T-2012-511805 (Patent Document 1 below) is known. The connector assembly comprises a plug outer housing having a flexible latch, a floating latch slidably connected to the plug outer housing, and a header outer housing fitted to the plug outer housing. . The floating latch has a substantially rectangular shape, and the inside is cut into a substantially rectangular shape. A locking tab that protrudes downward is provided at the rear of the floating latch.

  The flexible latch is provided with a lock claw portion protruding upward. The floating latch is locked to the flexible latch by the locking tab of the floating latch abutting the locking pawl of the flexible latch.

  However, when a mechanism for guaranteeing the fitting position is further added to the above configuration, it is necessary to separately provide a CPA (fitting position ensuring lock) for the plug outer housing. Thus, when two functions of the CPA and the latch are provided, it is necessary to attach two parts of the CPA and the latch to the plug outer housing, and there is a problem that the number of parts of the plug outer housing increases.

The connector disclosed in the present specification includes a first housing having a first lock portion including a first main lock portion and a first sub-lock portion, and a second lock portion, and is fitted to the first housing. A connector that includes a second housing that can be engaged, and a CPA latch that is attached to the first housing and is movable relative to the first lock portion, wherein the first main lock portion and the first lock The sub-block portions are respectively arranged along the fitting direction, and the CPA latch has a fitting guarantee release position capable of releasing the locked state of the first main lock portion and the second lock portion; A fitting guarantee position for guaranteeing a fitting state of the first housing and the second housing by overcoming a latching portion between the first main lock portion and the second lock portion from a fitting guarantee release position; Warranty solution In the disengagement operation stop state in which the disengagement operation is stopped by the first sub-block portion being engaged with the second lock portion during the disengagement of the first housing and the second housing from the position. By displacing the sub-block portion, it is possible to move between an operation stop release position where the locking of the first sub-block portion and the second lock portion can be released.
With this configuration, the CPA latch moves over the engaging portion between the first main lock portion and the second lock portion, and the CPA latch moves from the fitting guarantee release position to the fitting guarantee position, so that the first The fitting between the housing and the second housing can be guaranteed. When the first housing and the second housing are separated after the CPA latch is moved to the engagement guarantee release position, the first sub-block portion is locked to the second lock portion and the separation operation is stopped, and the separation operation is stopped. It becomes a state. In the disengagement operation stop state, the first housing and the second housing can be separated by moving the CPA latch to an operation stop release position where the engagement of the first sub-block portion and the second lock portion can be released. In this way, one CPA latch can realize two functions of a fitting guarantee function and a two-action disengagement function, as compared to the case where each function is realized by separate parts as in the past, The number of parts can be reduced.

The first housing includes a displacement restricting wall, the CPA latch includes a displacement restricting plate, and the displacement restricting plate is interlocked with the displacement of the first main lock portion and the first sub-block portion. When the first sub-block portion is displaced before moving to the operation stop release position in the disengagement stop state, the displacement restricting plate comes into contact with the displacement restricting wall, and the first sub-block is moved. It is good also as cancellation | release of the latching state of a part and a said 2nd lock part is prevented.
For example, if the engagement state of the first sub-block portion and the second lock portion can be released in the disengagement stop state before moving to the operation stop release position, the first action can be performed with one action without passing through the operation stop release position. The housing and the second housing can be detached. However, by adopting the above-described configuration, it is possible to prevent the locked state between the first sub-block portion and the second lock portion from being released in the disengagement stop state before moving to the operation stop release position. It is possible to prevent an unauthorized detachment operation such that the first housing and the second housing are separated without passing through the operation stop release position.

Further, when the first main lock portion is displaced at the fitting guaranteed position, the displacement restricting plate comes into contact with the displacement restricting wall, and the first main lock portion and the second lock portion are locked. It is also possible to prevent the release of.
For example, if the locked state of the first main lock portion and the second lock portion can be released at the fitting guaranteed position, the first housing and the second housing can be detached at the fitting guaranteed position. In this case, the first housing and the second housing are not guaranteed to be fitted. However, by adopting the above-described configuration, it is possible to prevent an unauthorized operation such as releasing the locked state of the first main lock portion and the second lock portion at the fitting guaranteed position.

  According to the connector disclosed in the present specification, two functions of a fitting guarantee function and a two-action detachment function can be realized by one CPA latch.

On the other hand, although not shown, when the first housing 10 and the second housing 50 are half-fitted (for example, the upper surface of the second lock portion 52 and the lower surface of the first main lock portion 16 are in contact), the CPA When the latch 30 is moved forward, the CPA arm distal end portion 36 comes into contact with the first main lock portion 16 and the forward movement of the CPA latch 30 is prevented. The lock part 16 cannot be overcome. As described above, when the first housing 10 and the second housing 50 are properly fitted, the CPA arm distal end portion 36 gets over the locking portion 70, and the CPA arm distal end portion 36 is located in front of the first main lock portion 16. Therefore, the CPA latch 30 can ensure the fitting.

  The CPA latch 30 includes a fitting guarantee position (position of the CPA latch 30 shown in FIGS. 11 and 12), a fitting guarantee release position (position of the CPA latch 30 shown in FIGS. 13 and 14), and an operation stop release position. (The position of the CPA latch 30 shown in FIGS. 18 and 19).

  As shown in FIGS. 11 and 12, the fitting guaranteed position is a state in which the CPA arm tip portion 36 of the CPA latch 30 gets over the locking portion 70 after the first housing 10 and the second housing 50 are fitted. This is the position of the CPA latch 30. In this state, when the rear part of the first lock arm 13 is pushed and displaced downward, and the first main lock part 16 is displaced upward, a pair of displacements of the CPA latch 30 attached on the first lock arm 13 The restriction plate 37 is also displaced upward, and the pair of displacement restriction plates 37 abut against the front displacement restriction wall 24.

Stopped (disengagement operation stopped state). At this time, although not shown, the electrical connection state between the female terminal of the first housing 10 and the male terminal of the second housing 50 is released.

  When the latch pressing portion 32 is pushed and displaced downward and the first sub-block portion 17 is displaced upward in the disengagement operation stop state, a pair of displacement regulation of the CPA latch 30 attached on the first lock arm 13 is achieved. The plate 37 is also displaced upward, and the pair of displacement restricting plates 37 abut against the pair of rear displacement restricting walls 25. As a result, the upward displacement of the first sub-block portion 17 is prevented, so that the first sub-block portion 17 and the second lock portion 52 are disengaged in an unauthorized state in the disengagement stop state. It is possible to prevent the operation.

  As shown in FIG. 18, in the disengagement stop state, the operation stop release position is such that the CPA latch 30 is pulled backward, and the latch lock convex portion 40 of the CPA latch 30 contacts the rear latch lock portion 28 of the first lock arm 13. This is the position of the CPA latch 30 in the contacted state. In this state, when the latch pressing portion 32 is pushed and displaced downward and the first sub-block portion 17 is displaced upward, unlike the above-described disengagement operation stop state, the pair of displacement restricting plates 37 are paired with the rear stage displacement restricting. Since it does not contact the wall 25, the contact between the first sub-block portion 17 and the second lock portion 52 is released as shown in FIG. As a result, the first housing 10 and the second housing 50 can be detached.

Next, the operation of this embodiment will be described.
As shown in FIG. 11 and FIG. 12, the first housing 10 is mounted on the second housing 50, and the CPA latch 30 is set to the fitting guaranteed position. From this state, the first housing 10 is detached from the second housing 50.

  First, the CPA latch 30 is pulled backward. At this time, the CPA arm main body portion 35 is flexibly displaced upward, the CPA arm tip portion 36 rides on the first sub-block portion 17, and the CPA arm tip portion 36 moves rearward. When the CPA latch 30 is further pulled rearward, the latch lock convex portion 40 comes into contact with the front latch lock portion 27 and the rearward movement of the CPA latch 30 is stopped. Thereby, the position of the CPA latch 30 becomes a fitting guarantee release position shown in FIGS.

  When the latch pressing portion 32 is pushed at the fitting guaranteed release position, the first main lock portion 16 is displaced upward as shown in FIGS. 15 and 16, and the first main lock portion 16 and the second lock portion 52 are displaced. Is released. When the first housing 10 is pulled rearward in this state, the first sub-block portion 17 comes into contact with the second lock portion 52. As a result, as shown in FIG. 17, the rearward movement of the first housing 10 is stopped, and the separation operation is stopped.

  When the CPA latch 30 is pulled rearward in the state where the detachment operation is stopped, the pair of latch lock arms 39 bends outward and the contact between the latch lock convex portion 40 and the preceding latch lock portion 27 is released. Further, when the CPA latch 30 is pulled rearward, as shown in FIGS. 18 and 19, the latch lock convex portion 40 comes into contact with the rear latch lock portion 28, and the rearward movement of the CPA latch 30 is stopped. As a result, the position of the CPA latch 30 becomes the operation stop release position.

  When the latch pressing portion 32 is pushed at the operation stop release position, the contact between the first sub-block portion 17 and the second lock portion 52 is released as shown in FIGS. When the first housing 10 is pulled rearward in this state, the separation of the first housing 10 from the second housing 50 is completed as shown in FIG.

  As described above, one CPA latch 30 can realize two functions of a fitting guarantee function and a two-action detachment function, as compared with the case where each function is realized by separate parts as in the past. The number of parts can be reduced.

  As described above, according to the present embodiment, the CPA latch 30 gets over the engaging portion 70 between the first main lock portion 16 and the second lock portion 52, and the CPA latch 30 is moved from the fitting guarantee release position to the fitting guarantee position. By being moved to, it is possible to ensure the fitting between the first housing 10 and the second housing 50. When the first housing 10 and the second housing 50 are detached after the CPA latch 30 has moved to the engagement guarantee release position, the first sub-block portion 17 is locked to the second lock portion 52 and the disengagement operation is stopped. Then, the disengagement operation is stopped. In the disengagement operation stop state, the CPA latch 30 is moved to an operation stop release position where the engagement of the first sub-block portion 17 and the second lock portion 52 can be released, so that the first housing 10 and the second housing 50 are separated. Is possible. Thus, one CPA latch 30 can realize the two functions of the fitting guarantee function and the two-action separation function, compared with the case where each function is realized by separate parts as in the prior art. The number of parts can be reduced.

  For example, if the first sub-block portion 17 and the second lock portion 52 can be released in the disengagement stop state before moving to the operation stop release position, the action stop release position can be released with one action. The first housing 10 and the second housing 50 can be detached. However, by adopting the configuration described above, it is possible to prevent the locked state between the first sub-block portion 17 and the second lock portion 52 from being released in the disengagement stop state before moving to the operation stop release position. Therefore, it is possible to prevent an unauthorized detachment operation in which the first housing 10 and the second housing 50 are detached without passing through the operation stop release position.

  For example, if the locked state of the first main lock portion 16 and the second lock portion 52 can be released at the fitting guaranteed position, the first housing 10 and the second housing 50 can be detached at the fitting guaranteed position. The fitting between the first housing 10 and the second housing 50 at the fitting guaranteed position is not guaranteed. However, by adopting the above-described configuration, it is possible to prevent an unauthorized operation such as releasing the locked state of the first main lock portion 16 and the second lock portion 52 at the fitting guaranteed position. .
