Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a connector. Background Technology

[0002] Connectors are extremely important electrical power transmission components in electric vehicles, including plugs and sockets that are adapted for mating. The plug has a handle, and when the handle is driven to turn from the pre-installed position to the locked position, the handle and the socket are connected by a mechanism such as a gear and rack.

[0003] To prevent the handle from accidentally disengaging from the locked position, the plug is equipped with a connector position assurance mechanism, namely the CPA (Connector Position Assurance) component. After the handle reaches the locked position, the CPA component moves from the initial position to the locked position and further locks the handle.

[0004] However, the aforementioned CPA component has the risk of accidentally moving from the initial position to the locked position when the plug is not inserted into the socket, which may adversely affect operation. Utility Model Content

[0005] This invention provides a connector to address the problem of the risk of accidental movement of CPA components when the plug is not inserted into the socket.

[0006] This utility model provides a connector including a plug and a socket. The plug is provided with a CPA component, which is movably assembled on the plug and has an initial position and a locked position. A positioning part extends from the CPA component, and the positioning part and the plug are engaged by a snap-fit ​​structure in the moving direction of the CPA component. The socket is provided with a push part that corresponds at least partially to the positioning part in the insertion direction. The push part pushes the positioning part to release the snap-fit ​​structure.

[0007] Optionally, the plug has a through hole, and the end of the positioning part away from the CPA component has a locking platform, which engages with the through hole to form the locking structure.

[0008] Optionally, the plug has a slot at one end facing the socket, the socket has a baffle corresponding to the slot, the through hole and the slot are connected and correspond to each other in the insertion direction, and the part of the baffle corresponding to the through hole constitutes the push part.

[0009] Optionally, the plug is further provided with a groove located on the movement path of the card holder. When the CPA component moves to the locking position, the card holder moves to the groove and engages with the groove.

[0010] Optionally, the sidewall of the groove near the through hole has a beveled structure.

[0011] Optionally, the positioning part extends along the moving direction of the CPA component, and the plug is provided with a receiving groove at the position corresponding to the positioning part, which is adapted to the moving path of the positioning part. The positioning part is received in the receiving groove, and the through hole and the groove are both provided at the bottom of the receiving groove.

[0012] Optionally, the plug is provided with a locking device and a press-lock. The locking device moves and engages with the press-lock to lock the plug and socket. The CPA component is provided with a locking part that extends out along the moving direction. When the CPA component moves to the locking position, the locking part is at least partially located below the press-lock.

[0013] Optionally, the locking part is provided with a first protrusion structure and a second protrusion structure at intervals, and the plug is provided with a stop block. The first protrusion structure and the second protrusion structure respectively cooperate with the stop block in the opposite movement direction of the CPA component when the CPA component is in the locked position and the initial position.

[0014] Optionally, the CPA component is provided with a limiting part extending along the moving direction. The limiting part has a protrusion on the side opposite to the plug. The plug has a limiting channel that is inserted and cooperates with the limiting part. The limiting channel has a first locking hole and a second locking hole spaced apart along the moving direction of the protrusion on the side wall opposite to the plug. The protrusion engages with the first locking hole and the second locking hole respectively to position the CPA component in the initial position and the locked position. The locking device is provided with a pressure block. When the locking device is engaged with the press lock, the pressure block enters the first locking hole and pushes the protrusion to release the engagement between the protrusion and the first locking hole.

[0015] Optionally, one of the CPA component and the plug is provided with a groove and the other is provided with a slide rail, and the groove and the slide rail are slidably engaged to realize the moving assembly of the CPA component and the plug.

[0016] This solution has the following beneficial effects:

[0017] The positioning part of this solution can position the CPA component in its initial position, and the positioning part can only be released from the positioning part by pushing the positioning part on the socket after the plug and socket are connected. This prevents the CPA component from accidentally leaving its initial position when the plug and socket are not connected, thus having a linkage effect.

[0048] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0049] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0051] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0052] like Figure 1-15As shown, an embodiment of the present invention provides a connector, including a plug 1 and a socket 2. The plug 1 is provided with a CPA component 13, which is movably mounted on the plug 1 and has an initial position and a locked position. The CPA component 13 is provided with a positioning part 131 extending from it. In the moving direction of the CPA component 13, the positioning part 131 and the plug 1 are engaged by a snap-fit ​​structure, thereby positioning the CPA component 13 in the initial position. The socket 2 is provided with a push part 22 that corresponds at least partially to the positioning part 131 in the insertion direction. After the plug 1 and the socket 2 are inserted, the push part 22 pushes the positioning part 131 to release the snap-fit ​​structure, thereby allowing the CPA component 13 to move from the initial position to the locked position.

[0053] It is understandable that the positioning part 131 can position the CPA part 13 in the initial position, and the positioning part 131 can only be released from the positioning part 131 by pushing the positioning part 131 after the plug 1 and the socket 2 are plugged in. This prevents the CPA part 13 from accidentally leaving the initial position when the plug 1 and the socket 2 are not plugged in, thus affecting the smooth operation. Therefore, the movement of the CPA part 13 in this solution has the effect of linkage with the plug 1 and socket 2 plugging action, further limiting the state and movement of the CPA part 13.

[0054] Furthermore, specifically considering the need to simplify the structure, such as Figure 3 , 4 As shown in Figures 10, 12, and 13, in this specific embodiment, the plug 1 is provided with a through hole 17, and the end of the positioning part 131 away from the CPA part 13 is provided with a locking platform 132. The locking platform 132 and the through hole 17 are engaged to form the above-mentioned locking structure. When the pushing part 22 pushes the locking platform 132 until it is disengaged from the through hole 17, the locking platform 132 and the through hole 17 are released from the locking engagement.

[0055] In addition, in this embodiment, setting the snap-fit ​​structure as a snap-fit ​​structure between the snap-fit ​​platform 132 and the through hole 17 has another beneficial effect, namely, the snap-fit ​​platform 132 can be accommodated in the through hole 17. The snap-fit ​​between the two and the setting of the through hole 17 do not have a substantial impact on the overall appearance of the plug 1, which is suitable for applications where the appearance requirements of the plug 1 are relatively strict.

[0056] Furthermore, to avoid adding additional structures, the existing socket 2 structure is fully utilized, such as... Figure 10 , 12As shown in Figures 1 and 13, in this embodiment, the end of the plug 1 facing the socket 2 is provided with a slot 16, and the socket 2 is provided with a baffle 21 corresponding to the slot 16. This structure is a conventional structure in the art. In this embodiment, the through hole 17 is connected and corresponds to the slot 16 in the insertion direction. Therefore, the part of the baffle 21 corresponding to the through hole 17 constitutes the above-mentioned push part 22. Thus, there is no need to design and add a structure on the socket 2 to form the push part 22, which simplifies the structure, avoids changes in appearance, and has reliable push capability.

[0057] Furthermore, in order to ensure that the locking plate 132 can also be accommodated after the CPA part 13 moves to the locking position, and to prevent the part of the positioning part 131 where the locking plate 132 is located from warping and causing unnecessary stress and appearance problems, such as... Figure 4 , 7 As shown in Figure 13, specifically in this embodiment, the plug 1 is also provided with a groove 172 located on the moving path of the locking platform 132. When the CPA component 13 moves to the locking position, the locking platform 132 moves to the groove 172 and engages with the groove 172. Thus, after the locking platform 132 engages with the groove 172, the locking platform 132 can be accommodated in the groove 172, and the deformation of the positioning part 131 caused by the locking platform 132 being pushed out of the through hole 17 by the pushing part 22 is restored.

[0058] Furthermore, to facilitate the return of CPA component 13 from the locked position to the initial position, such as... Figure 4 As shown, in this specific embodiment, the sidewall of the groove 172 near the through hole 17 is a sloped structure 173.

[0059] Furthermore, in order to improve the rationality of structural design, such as Figure 1 , 4 As shown in 6, 7, 8, and 9, in this specific embodiment, the positioning part 131 extends along the moving direction of the CPA part 13 and is located at the center line position in the moving direction of the CPA part 13. The plug 1 is provided with a receiving groove 171 adapted to the moving path of the positioning part 131 at the position corresponding to the positioning part 131. The positioning part 131 is received in the receiving groove 171. The through hole 17 and the groove 172 are both provided at the bottom of the receiving groove 171. The positioning part 131 being received in the receiving groove 171 can also reduce the impact on the appearance of the plug 1. The movement of the positioning part 131 can also improve the stability to a certain extent due to the guidance of the receiving groove 171. In addition, in this embodiment, in order to strengthen the structural strength of the positioning part 131, a reinforcing rib 139 is added between the positioning part 131 and the CPA part 13.

[0060] like Figure 1-15As shown, specifically in this embodiment, in combination with the locking requirements of plug 1 and socket 2, plug 1 is provided with locking device 11 and press lock 12. Locking device 11 moves and engages with press lock 12 to lock plug 1 and socket 2. CPA part 13 is provided with locking part 133 extending along the moving direction. When CPA part 13 moves to the locking position, locking part 133 is at least partially located below press lock 12 to realize the inherent design function of CPA part 13 locking locking device 11 twice.

[0061] In this embodiment, the locking device 11 is a handle structure rotatably mounted on the plug 1. The handle mechanism has a central locking part 111 and rotating parts 112 at both ends. The locking part 111 has a locking hook 113, and the pressing latch 12 has a locking groove 121. The locking hook 113 engages with the locking groove 121 to achieve the engagement of the locking part 111 and the pressing latch 12. This structure is a conventional technology in the art. Figure 2 , 15 As shown.

[0062] Furthermore, to prevent CPA component 13 from moving in the opposite direction of CPA in the initial and locked positions, such as... Figure 1 , 2 As shown in Figures 4, 6, 7, 12, and 13, in this specific embodiment, the locking part 133 is provided with a first protrusion structure 134 and a second protrusion structure 135 at intervals, and the plug 1 is provided with a stop block 18. The first protrusion structure 134 and the second protrusion structure 135 respectively cooperate with the stop block 18 in the opposite movement direction of the CPA part 13 when the CPA part 13 is in the locked position and the initial position.

[0063] To further position CPA component 13 in the initial and locked positions, such as Figure 1 , 2As shown in 5, 6, 7, 8, 9, 12, and 14, in this specific embodiment, a limiting part 136 is suspended on the CPA component 13 along the moving direction. A protrusion 137 is provided on the side of the limiting part 136 facing away from the plug 1. The plug 1 is provided with a limiting channel 14 that engages with the limiting part 136. A first locking hole 141 and a second locking hole 142 are provided at intervals along the moving direction of the protrusion 137 on the sidewall of the limiting channel 14 facing away from the plug 1. The protrusion 137 engages with the first locking hole 141 and the second locking hole 142 respectively to fix the CPA component 13. The locking device 11 is located in the initial position and the locked position. The locking device 11 is provided with a pressure block 114. Specifically, the pressure block 114 is provided on the locking part 111 of the locking device 11. When the locking device 11 is engaged with the pressing latch 12, the pressure block 114 enters the first locking hole 141 and pushes the protrusion 137 to release the engagement between the protrusion 137 and the first locking hole 141. The protrusion 137 enters the limiting channel 14. Then, when the CPA part 13 is moved to the locked position, the protrusion 137 moves to the second locking hole 142 and engages with the second locking hole 142.

[0064] Furthermore, one of the CPA component 13 and the plug 1 is provided with a groove 15, and the other is provided with a slide rail 138. The groove 15 and the slide rail 138 slide in engagement to realize the movable assembly of the CPA component 13 and the plug 1. Figure 2 , 3 As shown in 7, 8, 9, 11, and 12, in this specific embodiment, slide rails 138 are provided on both sides of the CPA component 13 in the moving direction, and corresponding slide grooves 15 are provided on the plug 1.

[0065] When plug 1 is not inserted into socket 2, CPA component 13 is in its initial position. At this time, the locking platform 132 engages with the through hole 17, the protrusion 137 engages with the first locking hole 141, and the second protruding structure 135 engages with the stop block 18. The locking device 11 does not move. When plug 1 is inserted into socket 2, the baffle 21 enters the slot 16, the pushing part 22 pushes the locking platform 132 and forces it to disengage from the engagement with the through hole 17, and then drives the locking device 11 to move until the locking hook 113 engages with the locking groove 1. 21. When the plug 137 is pressed by the pressure block 114, it enters the limiting channel 14 and drives the CPA part 13 to move to the locked position. At this time, the first protruding structure 134 passes over the stop block 18 and engages with the stop block 18. The protrusion 137 enters the second locking hole 142 and engages with the second locking hole 142. The locking platform 132 enters the groove 172. The locking part 133 is located below the pressing latch 12 and prevents the pressing latch 12 from being pressed. The plug 1 and the socket 2 are now connected.

[0066] Therefore, it can be understood that CPA component 13 is only allowed to move from the initial position to the locked position after the plug 1 and socket 2 are plugged in, thereby preventing CPA component 13 from accidentally leaving the initial position when the plug 1 and socket 2 are not plugged in, which would affect the smooth operation. Therefore, the action of CPA component 13 in this solution has the effect of linkage with the plug 1 and socket 2 plugging action, further limiting the state and movement of CPA component 13.
