Description

Technical Field

[0001] This utility model relates to the field of vehicle connector technology, and in particular to a connector and a vehicle. Background Technology

[0002] Currently, connector assemblies are devices that connect two active components to transmit current or signals. A connector assembly typically includes male and female terminals that mate together, enabling the transmission of information or current after mating. To prevent the male and female terminals from loosening during vibration, a CPA (Connector Position Assurance) component is often installed on the female terminal. After mating, the CPA component is inserted between the cantilever and the female terminal to support the cantilever, preventing it from being pressed open and thus achieving a secondary locking mechanism for the connector assembly.

[0003] In the existing technology, when the male and female terminals are not fully inserted, the CPA component placed under the cantilever can easily be pushed into the final position, causing the cantilever to be pre-lifted. At this time, the male and female terminals cannot be inserted into the correct position. The CPA component needs to be moved first before the male and female terminals can be inserted into the correct position, which affects the assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a connector and vehicle to solve the problem in the prior art where the CPA component is easily pushed into its final position when the male and female ends are not fully inserted, resulting in low assembly efficiency.

[0005] On one hand, this utility model provides a connector, which includes: a housing; a cantilever, one end of which is connected to the housing, and the other end of which extends away from the housing, the cantilever having a limiting protrusion and an abutment groove; and a CPA assembly, including a body and an extension arm, the extension arm having an abutment tip, one end of which is connected to the body, and the other end of which extends away from the housing, the body being slidably disposed on the housing to move the other end of the extension arm between the housing and the cantilever, so that the abutment tip is located in the abutment groove, the abutment tip abuts against the inner wall of the abutment groove, and the extension arm being deformable to disengage the abutment tip from the abutment groove and engage with the limiting protrusion.

[0006] As an optional technical solution for the connector, the abutment groove is disposed on the side of the limiting protrusion facing the main body and extends to the end face of the limiting protrusion facing the outer shell.

[0007] As an optional technical solution for the connector, the abutment groove has an abutment surface, the abutment surface is disposed away from the housing, and the abutment tip abuts against the abutment surface.

[0008] As an optional technical solution for the connector, the abutment groove also has a limiting surface connected to the abutment surface, the limiting surface being disposed towards the housing, and the included angle between the limiting surface and the abutment surface being A, 60°≤A≤70°.

[0009] As an optional technical solution for the connector, the cantilever is provided with a first limiting hole and a second limiting hole. The first limiting hole is located between the limiting protrusion and the other end of the cantilever, and the second limiting hole is located between the limiting protrusion and one end of the cantilever. The abutment groove is located in the first limiting hole, and the other end of the extension arm can be moved to the second limiting hole and engaged with the limiting protrusion.

[0010] As an optional technical solution for the connector, the extension arm includes an elastic arm and a pressing protrusion. One end of the elastic arm is connected to the main body, and the other end of the elastic arm is connected to the pressing protrusion. The pressing protrusion can be pressed to deform the elastic arm. The end of the pressing protrusion opposite to the elastic arm has the abutting tip.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides a connector comprising a housing, a cantilever, and a CPA assembly. The cantilever has a limiting protrusion with an abutment groove. The CPA assembly includes a main body and an extension arm. Using this connector, when the male and female ends are not fully inserted, the abutment tip of the extension arm is always located within the abutment groove, abutting against the inner wall of the groove. This design allows the abutment groove to limit movement in the sliding direction of the main body, effectively preventing the extension arm from being pre-push up and easily pushed to its final position, thus improving assembly efficiency. By incorporating the abutment groove, this connector effectively solves the problem in existing technologies where the CPA assembly is easily pushed into its final position when the male and female ends are not fully inserted, resulting in low assembly efficiency.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 4As shown, this embodiment provides a connector, which includes a housing 1, a cantilever 2, and a CPA assembly 3. One end of the cantilever 2 is connected to the housing 1, and the other end of the cantilever 2 extends away from the housing 1. The cantilever 2 has a limiting protrusion 21 with an abutment groove 22. The CPA assembly 3 includes a body 31 and an extension arm 32. The extension arm 32 has an abutment tip 321. One end of the extension arm 32 is connected to the body 31, and the other end of the extension arm 32 extends away from the housing 1. The body 31 is slidably disposed on the housing 1 to move the other end of the extension arm 32 between the housing 1 and the cantilever 2, so that the abutment tip 321 is located in the abutment groove 22 and abuts against the inner wall of the abutment groove 22. The extension arm 32 can deform to disengage the abutment tip 321 from the abutment groove 22 and engage with the limiting protrusion 21.

[0030] The connector of this invention ensures that when the male and female ends are not fully inserted, the abutting tip 321 of the extension arm 32 remains within the abutting groove 22, allowing the abutting tip 321 to abut against the inner wall of the abutting groove 22. This design allows the abutting groove 22 to limit the sliding direction of the main body 31, effectively preventing the extension arm 32 from being pre-pushed up and easily pushed to its final position, thus improving assembly efficiency. By using the connector of this invention and incorporating the abutting groove 22, the problem of low assembly efficiency caused by the CPA component 3 being easily pushed into its final position when the male and female ends are not fully inserted in the prior art is effectively solved.

[0031] In some embodiments, the abutment groove 22 is disposed on the side of the limiting protrusion 21 facing the main body 31 and extends to the end face of the limiting protrusion 21 facing the outer shell 1. This arrangement facilitates the disengagement of the extension arm 32 from the abutment groove 22 when it needs to be pushed to the final position, thereby improving assembly efficiency.

[0032] Furthermore, the abutment groove 22 has an abutment surface 221, wherein the abutment surface 221 is disposed away from the outer shell 1. This arrangement facilitates the abutment tip 321 to abut against the abutment surface 221, thereby playing a limiting role.

[0033] In this embodiment, the abutment groove 22 also has a limiting surface 222 connected to the abutment surface 221, wherein the limiting surface 222 is disposed facing the outer shell 1, and the included angle between the limiting surface 222 and the abutment surface 221 is A, 60°≤A≤70°. This arrangement limits the included angle A between the limiting surface 222 and the abutment surface 221 to the above-mentioned angle range, making it less likely for the abutment tip 321 to detach when it abuts against the inner wall of the abutment groove 22, thereby preventing the extension arm 32 from being pre-pushed up and easily pushed to the final position.

[0034] Specifically, the included angle A between the limiting surface 222 and the contact surface 221 can be selected according to the actual situation. The included angle A between the limiting surface 222 and the contact surface 221 can be selected as 60°, 65° or 70°, etc.

[0035] In some embodiments, the cantilever 2 is provided with a first limiting hole 23 and a second limiting hole 24. The first limiting hole 23 is located between the limiting protrusion 21 and the other end of the cantilever 2, the second limiting hole 24 is located between the limiting protrusion 21 and one end of the cantilever 2, the abutment groove 22 is located in the first limiting hole 23, and the other end of the extension arm 32 can move to the second limiting hole 24 and engage with the limiting protrusion 21.

[0036] When the connector leaves the factory, the main body 31 is installed on the outer shell 1, so that the other end of the extension arm 32 is located inside the first limiting hole 23. The abutment groove 22 blocks the abutment tip 321, so that the main body 31 cannot slide to the final position. The other end of the extension arm 32 can move to the second limiting hole 24 and engage with the limiting protrusion 21 (i.e., move to the final position).

[0037] In this embodiment, the extension arm 32 includes an elastic arm 322 and a pressing protrusion 323. One end of the elastic arm 322 is connected to the main body 31, and the other end of the elastic arm 322 is connected to the pressing protrusion 323. The pressing protrusion 323 is pressable, thereby deforming the elastic arm 322 and moving the pressing protrusion 323 from the first limiting hole 23 to the second limiting hole 24. The end of the pressing protrusion 323 facing away from the elastic arm 322 has an abutting tip 321, which facilitates abutment against the inner wall of the abutting groove 22.

[0038] In some embodiments, the pressing protrusion 323 is triangularly arranged. The tip of the pressing protrusion 323 protrudes from the first limiting hole 23, which facilitates pressing by the operator.

[0039] In this embodiment, the CPA assembly 3 also includes a support block 33, which is disposed on the main body 31. The support block 33 can support the other end of the cantilever 2 after the other end of the extension arm 32 is supported by the limiting protrusion 21. This configuration allows the support block 33 to support the other end of the cantilever 2 after the limiting protrusion 21, thereby facilitating the subsequent assembly of the connector and improving the assembly efficiency of the connector assembly.

[0040] In some embodiments, the housing 1 has a groove 11, and the main body 31 is slidably disposed in the groove 11. The groove 11 is disposed along the insertion direction of the housing 1. In this configuration, the groove 11 can guide the housing 1 during assembly, thereby improving assembly efficiency.

[0041] This embodiment also provides a vehicle including the connector described above. In the vehicle using this invention, when the male and female ends are not fully inserted, the abutting tip 321 of the extension arm 32 is always located within the abutting groove 22, causing the abutting tip 321 to abut against the inner wall of the abutting groove 22. This configuration allows the abutting groove 22 to limit the sliding direction of the main body 31, effectively preventing the extension arm 32 from being pre-pushed up and easily pushed to its final position, thus improving assembly efficiency. The vehicle using this invention, by providing the abutting groove 22, effectively solves the problem in the prior art where, when the male and female ends are not fully inserted, the CPA component 3 is easily pushed into its final position, resulting in low assembly efficiency.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
