Technical Field

The technology disclosed by this specification relates to a connector.

Background

As an example of a conventional connector, a connector assembly described in japanese patent laying-open No. 2012 and 511805 (patent document 1) is known. The connector assembly is composed of: a plug outer housing having a flexible latch; a floating latch slidably connected to the plug outer housing; and a socket outer case fitted with the plug outer case. The floating latch is formed in a generally rectangular shape with an interior cut out in a generally rectangular shape. A lock projection projecting downward is provided at the rear of the floating latch.

The flexible latch is provided with a locking claw portion protruding upward. The floating latch is latched to the flexible latch by the locking protrusion of the floating latch abutting against the locking claw of the flexible latch. Further, the socket outer case is provided with a projection projecting upward. The projection abuts against the inner wall in front of the floating latch, and the receptacle outer housing is locked to the floating latch.

To release the fitting between the receptacle outer housing and the plug outer housing, the floating latch and the flexible latch are first released from locking. Then, the floating latch and the outer housing of the receptacle are released from the engagement. Thus, the fitting between the socket outer case and the plug outer case is released by two operations.

Disclosure of Invention

Problems to be solved by the invention

However, when a mechanism for securing the fitting position is further added to the above-described structure, it is necessary to additionally provide CPA (fitting position securing lock) to the plug outer housing. In the case where the two functions of the CPA and the latch are thus provided, it is necessary to install two members of the CPA and the latch in the plug outside housing, so that there is a problem that the number of members of the plug outside housing increases.

Means for solving the problems

The connector disclosed in the present specification includes: a 1 st housing having a 1 st locking portion; a 2 nd housing having a 2 nd locking portion locked to the 1 st locking portion and capable of being fitted to the 1 st housing; and a CPA latch which is relatively movable with respect to the 1 st locking portion, the CPA latch being movable between a release position at which the CPA latch can release the locked state of the 1 st locking portion and the 2 nd locking portion, a fitting-securing position at which the CPA latch secures the fitted state of the 1 st housing and the 2 nd housing by crossing over the locking portion of the 1 st locking portion and the 2 nd locking portion from the release position, and an operation stop position at which the CPA latch stops the disengaging operation by being locked to the 2 nd locking portion in the middle of the disengagement of the 1 st housing and the 2 nd housing.

With this configuration, the CPA latch moves from the release position to the fitting-securing position by the CPA latch crossing the locking portions of the 1 st and 2 nd locking portions, and the fitting of the 1 st and 2 nd housings can be secured. When the 1 st housing and the 2 nd housing are separated after the CPA latch is moved to the release position, the CPA latch is locked by the 2 nd locking portion to stop the separation operation, and the position of the CPA latch becomes the operation stop position. Thus, two functions of securing the fitting function and the disengaging function of the two operations can be realized by one CPA latch, and the number of parts can be reduced as compared with the case where the functions are realized by different parts as in the related art.

In addition, the CPA latch may include a latch portion and a latch pressing portion, wherein the disengagement operation is stopped when the latch portion and the 2 nd locking portion are brought into contact with each other at the operation stop position, and when the latch pressing portion is displaced, the latch portion is displaced in a direction opposite to the latch pressing portion to release the contact between the latch portion and the 2 nd locking portion, so that the 1 st housing and the 2 nd housing can be disengaged from each other.

With this configuration, when the engagement between the 1 st housing and the 2 nd housing is released by releasing the contact between the 2 nd locking portion and the latch portion at the operation stop position, the latch pressing portion of the CPA latch is pressed and displaced, and the latch portion is also displaced like a seesaw, so that the engagement can be released.

In addition, the 1 st housing may include a projection portion, and the displacement of the latch pressing portion may be prevented by the CPA latch and the projection portion coming into contact with each other at the release position, and the displacement of the latch pressing portion may be allowed by the CPA latch and the projection portion not coming into contact with each other at the operation stop position.

For example, in the case where the latch pressing portion is displaceable at the release position, when the 1 st and 2 nd housings are separated from each other while the 1 st and latch pressing portions are simultaneously pressed at the release position, the 1 st and 2 nd housings can be separated from each other by one operation without passing through the operation stop position. However, if the displacement of the latch pressing portion of the CPA latch is inhibited at the release position as in the above-described configuration, it is possible to prevent an unauthorized disengaging operation from being performed to disengage the 1 st housing and the 2 nd housing without passing through the operation stop position.

Further, the CPA latch may include a displacement restricting portion that suppresses displacement of the 1 st lock portion at the assured fitting position and maintains the locked state of the 1 st lock portion and the 2 nd lock portion.

For example, in the case where the 1 st locking portion is displaceable in the fitting position is ensured, the 1 st housing and the 2 nd housing are disengageable in the fitting position is ensured. However, with the above configuration, the displacement restricting portion of the CPA latch suppresses the displacement of the 1 st locking portion, and therefore the 1 st housing and the 2 nd housing can be prevented from coming off at the assured fitting position.

Effects of the invention

According to the connector disclosed in the present specification, two functions of securing the fitting function and the disengaging function of the two actions can be realized by one CPA latch.

Detailed Description

< embodiment >

An embodiment will be described with reference to fig. 1 to 19.

As shown in fig. 8, the connector 1 according to the present embodiment includes a 1 st housing 10, a CPA latch 30 attached to the 1 st housing 10, and a 2 nd housing 50 fitted to the 1 st housing 10. In the following description, the mating surface side of the 1 st casing 10 and the 2 nd casing 50 is referred to as the front side, and the Z direction in fig. 8 is referred to as the upper side.

As shown in fig. 5 and 6, the 1 st housing 10 is a female housing, and includes a 1 st front opening 11 that opens forward, a 1 st rear opening 12 that opens rearward, and a lock arm 13. Two 1 st cavities 20 are provided in the 1 st housing 10 so as to open, and female 1 st terminals are inserted into the respective cavities, although not shown.

As shown in fig. 3, 4, and 8, the lock arm 13 is formed in a shape elongated in the front-rear direction, and includes a 1 st frame portion 14, a 1 st pressing portion 15, a base end portion 16, and a 1 st locking portion 17, which are formed in a rectangular frame shape. Here, the section lines of the lock arm 13 shown in fig. 8 to 19 are different from those of the 1 st housing 10, but the lock arm 13 and the 1 st housing 10 are integrated and have different section lines for easy viewing.

The base end portion 16 is provided to protrude downward from the lower surface of the 1 st frame portion 14 and is continuous with the upper surface of the 1 st rear opening 12. The 1 st pressing portion 15 is formed in a square shape and is provided at a rear portion of the 1 st frame portion 14. The 1 st locking portion 17 is provided at the distal end portion of the 1 st frame portion 14. As shown in fig. 12, the lock arm 13 is elastically displaceable in a seesaw manner with the base end portion 16 as a fulcrum, and when the 1 st pressing portion 15 is displaced downward, the 1 st locking portion 17 is displaced upward.

As shown in fig. 3, a restricting wall 18 for restricting forward movement of a CPA latch 30 described later is provided between the upper surface of the 1 st front opening 11 and the upper surface of the 1 st rear opening 12.

As shown in fig. 8 and 9, a protrusion 19 protruding upward is provided near the center of the upper surface of the 1 st rear opening 12. As shown in fig. 11, the projection 19 is provided to abut against a CPA latch 30 described later and restrict downward displacement of the CPA latch 30.

As shown in fig. 1 and 2, the CPA latch 30 is formed in a shape elongated in the front-rear direction, and includes a CPA latch main body portion 37 formed in a square shape, a latch frame portion 31 formed in a gate shape, a latch pressing portion 32, a displacement restricting portion 34, and a CPA arm 38.

As shown in fig. 1 and 2, the latch pressing portion 32 is formed in a square shape and provided to protrude upward from the rear portion of the CPA latch main body portion 37. Further, a front movement restricting portion 35 is provided to protrude from a rear side surface of the latch frame portion 31. The forward movement restricting portion 35 is provided to protrude laterally from the lower side surface of the latch pressing portion 31 and further protrude forward.

The latch frame portion 31 is provided to protrude forward from the front end portion of the CPA latch main body portion 37. The front frame of the latch frame portion 31 is a latch portion 33. The lower surface of the latch 33 is tapered toward the front.

The CPA arm 38 is cantilevered and includes the displacement restricting portion 34 and the CPA portion 36. The displacement restricting portion 34 is provided to protrude forward from the front end portion of the CPA latch main body portion 37. The CPA portion 36 is provided to protrude downward from the front end portion of the displacement restricting portion 34. The displacement restricting portion 34 has flexibility in the up-down direction, and thereby the CPA portion 36 can be displaced in the up-down direction.

As shown in fig. 5 and 6, the CPA latch 30 is assembled to the lock arm 13 of the 1 st housing 10. As shown in fig. 8 and 10, the CPA latch 30 is slidable on the lock arm 13, and is movable in the front-rear direction. When the CPA latch 30 is moved forward by a predetermined amount or more, the forward movement restricting portion 35 of the CPA latch 30 abuts against the restricting wall 18 of the 1 st housing 10. Thereby, forward movement of the CPA latch 30 by a certain amount or more is restricted.

When the CPA latch 30 is moved rearward, as shown in fig. 11, the lower surface of the CPA latch main body portion 37 located below the latch pressing portion 32 abuts against the projection portion 19 of the 1 st housing 10. This restricts downward displacement of the latch pressing portion 32. When the latch pressing portion 32 is displaced downward in a state where the rear end portion of the CPA latch main body portion 37 located below the latch pressing portion 32 is located forward of the protrusion 19 and rearward of the base end portion 16 as shown in fig. 15, a portion of the 1 st housing 10 on the rear side across the base end portion 16 is also pressed as shown in fig. 16 and 17, and the latch pressing portion 32 is displaced downward together with the 1 st pressing portion 15. Thereby, the latch 33 and the 1 st lock 17 are displaced upward.

As shown in fig. 8, the 2 nd housing 50 is a male-side housing, and includes a 2 nd opening 51 that opens on a fitting surface to be fitted to the 1 st housing 10, and a 2 nd locking portion 52. Although not shown, the 2 nd housing 50 has two 2 nd cavities provided in its opening, and male-side 2 nd terminals are inserted into the cavities. The 2 nd locking part 52 is provided to protrude upward from the upper surface of the 2 nd opening part 51. The 2 nd locking part 52 is formed in a tapered shape tapered toward the fitting direction with the 1 st housing 10. Thus, when the 1 st housing 10 and the 2 nd housing 50 are fitted to each other, the 1 st lock portion 17 and the latch portion 33 first come into contact with the 2 nd tapered portion 53 of the 2 nd lock portion 52, so that the 1 st lock portion 17 and the latch portion 33 are easily displaced upward, and the insertion force of the 1 st housing 10 is reduced.

When the 1 st housing 10 and the 2 nd housing 50 are fitted, as shown in fig. 8, the 1 st locking part 17 abuts on the 2 nd locking part 52, and the 1 st locking part 17 is latched to the 2 nd locking part 52. In this state, although not shown, the 1 st terminal of the 1 st housing 10 and the 2 nd terminal of the 2 nd housing 50 are electrically connected.

When the CPA latch 30 is moved forward in a state where the 1 st housing 10 and the 2 nd housing 50 are fitted, as shown in fig. 8, the CPA portion 36 rides over the locking portions 70 of the 1 st locking portion 17 and the 2 nd locking portion 52, the lower surface of the CPA portion 36 and the upper surface of the 1 st locking portion 17 slide, and the CPA portion 36 is pushed in front of the 1 st locking portion 17. On the other hand, although not shown, when the 1 st housing 10 and the 2 nd housing 50 are half fitted (for example, in a state where the upper surface of the 2 nd lock 52 and the lower surface of the 1 st lock 17 are in contact), the CPA portion 36 cannot straddle over the 1 st lock 17. In this way, when the 1 st housing 10 and the 2 nd housing 50 are properly fitted, the CPA portion 36 rides over the locking portion 70, and the CPA portion 36 is pushed in front of the 1 st locking portion 17, so that the fitting can be ensured by the CPA latch 30. When the 1 st pressing part 15 of the 1 st housing 10 is pressed in this state to displace the 1 st locking part 17 upward, the 1 st locking part 17 comes into contact with the displacement restricting part 34 of the CPA latch 30, and the upward displacement of the 1 st locking part 17 is restricted.

The CPA latch 30 is movable between a secure fitting position (the position of the CPA latch 30 shown in fig. 8 and 9), a release position (the position of the CPA latch 30 shown in fig. 10 and 11), and an operation stop position (the position of the CPA latch 30 shown in fig. 14 and 15). Here, as shown in fig. 8, the assured fitting position is a position of the CPA latch 30 in a state where the CPA portion 36 of the CPA latch 30 has spanned the locking portion 70 after the 1 st and 2 nd housings 10, 50 are fitted. As shown in fig. 10, the release position is a position where the CPA latch 30 is pulled rearward from the fitting-securing position and the latch portion 33 abuts against the 1 st locking portion 17. In addition, in the release position, when the 1 st housing 10 and the 2 nd housing 50 are disengaged, as shown in fig. 12 to 14, the latch portion 33 is hooked to the 2 nd locking portion 52, and the CPA latch 30 moves forward. When the CPA latch 30 moves forward, the forward movement restricting portion 35 of the CPA latch 30 abuts against the restricting wall 18 of the 1 st housing 10, and the forward movement of the CPA latch 30 is stopped in a state where the latch portion 33 abuts against the 2 nd lock portion 52. Thus, the 1 st housing 10 is prevented from being separated from the 2 nd housing 50. The position of the CPA latch 30 at this time becomes the operation stop position.

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

As shown in fig. 8 and 9, the 1 st housing 10 and the 2 nd housing 50 are fitted to each other, and the CPA latch 30 is moved from the release position to the secure fitting position. In this state, even if the 1 st pressing part 15 is pressed to displace the 1 st locking part 17 upward, the upper surface of the 1 st locking part 17 comes into contact with the displacement restricting part 34 of the CPA latch 30, and the upward displacement is prevented. This prevents the 1 st housing 10 from being detached from the 2 nd housing 50 at the fitting position.

To release the fitting between the 1 st housing 10 and the 2 nd housing 50, the CPA latch 30 is first pulled rearward. At this time, the displacement restricting portion 34 is flexibly displaced upward, the CPA portion 36 rides over the 1 st locking portion 17, and the CPA portion 36 is moved rearward. When the CPA latch 30 is further pulled rearward, as shown in fig. 10, the latch portion 33 of the CPA latch 30 abuts on the 1 st locking portion 17, and the rearward movement of the CPA latch 30 is stopped. Thereby, the position of the CPA latch 30 becomes the release position. In the release position, even if the latch pressing portion 32 is pressed to displace the latch portion 33 upward, as shown in fig. 11, the lower surface of the latch frame portion 31 abuts against the protrusion 19 of the 1 st housing 10, so that the latch portion 33 cannot be displaced upward. Thus, in the release position, for example, an improper separation operation of separating the 1 st case 10 and the 2 nd case 50 while simultaneously pressing the 1 st pressing portion 15 and the latch pressing portion 32 is prevented.

Subsequently, the locking of the 1 st locking part 17 and the 2 nd locking part 52 is released. First, as shown in fig. 12, the 1 st pressing part 15 is pressed to displace the 1 st locking part 17 upward. Next, as shown in fig. 13, when the 1 st housing 10 is pulled rearward, the latch portion 33 of the CPA latch 30 and the 2 nd locking portion 52 abut against each other. At this time, although not shown, the electrical connection state between the 1 st terminal of the 1 st housing 10 and the 2 nd terminal of the 2 nd housing 50 is released.

When the 1 st housing 10 is further pulled rearward, as shown in fig. 14, the latch 33 abuts and hooks on the 2 nd locking portion 52, and the CPA latch 30 moves forward. After that, the front movement restricting portion 35 of the CPA latch 30 abuts on the restricting wall 18 of the 1 st housing 10, and the 1 st housing 10 is prevented from moving backward. Thereby, the position of the CPA latch 30 becomes the operation stop position. In the operation stop position, as shown in fig. 15 and 17, the rear end portion of the CPA latch main body portion 37 located below the latch pressing portion 32 is located forward of the protrusion 19 and rearward of the base end portion 16, and therefore the latch pressing portion 32 can be pressed to displace the latch 33 upward.

Next, the 1 st case 10 and the 2 nd case 50 are detached. First, as shown in fig. 16, the latch pressing portion 32 is pressed. Then, the lower surface of the latch pressing portion 32 abuts on the lock arm 13 of the 1 st housing 10, and therefore the rear portion of the lock arm 13 is pressed downward, and the 1 st pressing portion 15 is also displaced downward in conjunction therewith. Thereby, the latch portion 33 of the CPA latch 30 and the 1 st locking portion 17 are displaced upward. Next, when the 1 st housing 10 is pulled rearward in this state, as shown in fig. 18, the lower surface of the CPA latch 30 slides on the 2 nd locking portion 52, and at the same time, the CPA latch 30 moves rearward. When the 1 st housing 10 is further pulled rearward, as shown in fig. 19, the 1 st housing 10 and the 2 nd housing 50 are separated, and the fitting of the 1 st housing 10 and the 2 nd housing 50 is released. Since the latch 33 can be displaced upward in a see-saw shape by pressing the latch pressing portion 32 in this way, the operation of releasing the engagement at the operation stop position can be simplified as compared with a case where the latch 33 is directly lifted and displaced upward, for example.

As described above, the two functions of securing the fitting function and the disengagement function of the two operations can be realized by one CPA latch 30, and the number of components can be reduced as compared with the case where the respective functions are realized by different components as in the related art.

As described above, according to the present embodiment, the CPA latch 30 moves from the release position to the fitting securing position across the locking portions 70 of the 1 st locking portion 17 and the 2 nd locking portion 52, and the CPA latch 30 is moved, whereby the fitting of the 1 st housing 10 and the 2 nd housing 50 can be secured. When the 1 st housing 10 and the 2 nd housing 50 are disengaged after the CPA latch 30 has moved to the release position, the CPA latch 30 is locked to the 2 nd locking portion 52, the disengaging operation is stopped, and the position of the CPA latch 30 becomes the operation stop position. Thus, two functions of securing the fitting function and the disengaging function of the two operations can be realized by one CPA latch 30, and the number of components can be reduced as compared with the case where the functions are realized by different components as in the related art.

Further, when the contact between the 2 nd locking portion 52 and the latch portion 33 is released and the fitting between the 1 st housing 10 and the 2 nd housing 50 is released at the operation stop position, the latch pressing portion 32 of the CPA latch 30 is pressed and displaced, whereby the latch portion 33 is also displaced like a seesaw, and the fitting can be released, so that the operation of releasing the fitting at the operation stop position can be simplified as compared with a case where the latch portion 33 is directly lifted and displaced upward, for example.

For example, when the latch pressing portion 32 is displaceable at the release position, when the 1 st case 10 and the 2 nd case 50 are separated from each other in a state where the 1 st pressing portion 15 and the latch pressing portion 32 are simultaneously pressed at the release position, the 1 st case 10 and the 2 nd case 50 can be separated from each other by one operation without passing through the operation stop position. However, if the displacement of the latch pressing portion 32 of the CPA latch 30 is stopped at the release position as in the above-described configuration, an unauthorized disengaging operation of disengaging the 1 st housing 10 and the 2 nd housing 50 without passing through the operation stop position can be prevented.

For example, in the case where the 1 st locking part 17 is displaceable in the fitting position is ensured, the 1 st housing 10 and the 2 nd housing 50 can be disengaged in the fitting position is ensured. However, when the above-described structure is adopted, the displacement restricting portion 34 of the CPA latch 30 suppresses the displacement of the 1 st locking portion 17, and therefore the 1 st housing 10 and the 2 nd housing 50 can be prevented from coming off at the assured fitting position.

< other embodiment >

The technology disclosed in the present specification is not limited to the embodiments described above and illustrated in the drawings, and includes, for example, the following various embodiments.

(1) In the present embodiment, the 1 st case 10 is a female case and the 2 nd case 50 is a male case, but the opposite is also possible.

(2) In the present embodiment, when the latch pressing portion 32 is pressed, a portion of the lock arm 13 on the rear side with respect to the base end portion 16 is also pressed, and the latch pressing portion 32 is displaced downward together with the 1 st pressing portion 15, but the latch pressing portion 32 and the 1 st pressing portion 15 may be displaced downward independently.

(3) In the present embodiment, the downward displacement of the latch pressing portion 32 is prevented by the CPA latch 30 abutting against the projection portion 19 in the release position, but for example, a projection may be provided on a side surface of the latch main body portion and a groove may be further provided on an inner wall of the 1 st housing 10, and the downward displacement of the latch pressing portion 32 may be prevented by the projection entering the groove provided in the 1 st housing 10 in the release position.

(4) In the present embodiment, the CPA latch 30 is movable in the front-rear direction, but may be movable in other directions, for example, movable in a direction intersecting the fitting direction, and may be set to the secure fitting position when moved in one direction and the release position when moved in the other direction.
