Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to an integrated connector structure. Background Art

[0002] At present, in automotive lighting fixtures, connectors are generally installed on the housing through a fixed structure at the wire harness end. The fixed structure on the housing that cooperates with the connector often occupies a large external space, which is inconsistent with the current trend of lightweight and miniaturization of lamps. At the same time, the commonly used wiring scheme currently requires connecting a section of wire harness from the PCB board inside the lamp to the connector, which not only requires consideration of assembly issues, but also causes waste of resources and increased costs. It can be seen that the layout of the wire harness connector is not only related to the external space of the lamp, but also has an important impact on the assembly process and production cost of the product. How to design a small, low-cost, and simple-structured lamp harness connector structure in the limited engine compartment space has always been a technical problem that needs to be solved urgently. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an integrated connector structure, which realizes the miniaturization of the external connector of the lamp and eliminates the matching structure of the shell and the connector.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An integrated connector structure includes a lamp housing and a PCB board arranged inside the lamp housing, a connector is formed on one side of the outside of the lamp housing, and the connector and the lamp housing are integrally injection molded, an end of the PCB board close to the connector is connected to a pin structure, and an end of the pin structure away from the PCB board passes through the lamp housing and extends into the connector.

[0006] Furthermore, the pin structure includes two L-shaped pins, and one end of the short side of the L-shaped pin is plugged into the PCB board and welded.

[0007] Furthermore, two matching holes are provided at the connection between the connector and the lamp housing, and one end of the long sides of the two L-shaped pins respectively passes through the two matching holes and extends into the connector.

[0008] Furthermore, the connector is a double-hole structure.

[0009] Furthermore, one end of the long sides of the two L-shaped pins is parallel to the side wall of the connector.

[0010] Furthermore, the thickness of the connection between the lamp housing and the connector is greater than the thickness of other positions of the lamp housing.

[0011] By adopting the above technical solution, the utility model has the following beneficial effects:

[0012] 1. The utility model design integrates the connector and the lamp housing into an integral injection molding, and uses a pin structure with one end welded on the PCB board and the other end inserted into the connector to form a quick conduction. This not only allows the PCB board and the connector to be directly matched, eliminating the wiring harness between the PCB board and the connector, overcoming the problem of short life of the wiring harness loss, but also eliminates the matching structure between the lamp housing and the connector, thereby making the overall structure lighter and more compact, and the structure is simple, easy to assemble, and can save costs.

[0013] 2. The utility model adopts an integrated design of the connector and the lamp housing, and thickens the connection between the lamp housing and the connector, thereby extending the service life of the connector, making it less likely to be damaged or broken, and having higher safety performance.

[0018] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, in this embodiment, an integrated connector structure is provided, which is mainly composed of a lamp housing 1, a PCB board 2, a pin structure 3, a connector 4 and other components. Among them, the PCB board 2 is fixedly installed inside the lamp housing 1, the connector 4 is formed on one side of the outside of the lamp housing 1, and the connector 4 and the lamp housing 1 are integrally injection molded, one end of the pin structure 3 is connected to the end of the PCB board 2 close to the connector 4, and the end of the pin structure 3 away from the PCB board 2 passes through the lamp housing 1 and extends into the connector 4.

[0020] Specifically, the pin structure 3 in this embodiment includes two L-shaped pins, one end of the short side of the L-shaped pin is plugged into the PCB board 2 and fixed by soldering, which can ensure conduction and achieve structural stability. At the same time, two matching holes 5 are opened at the connection between the lamp housing 1 and the connector 4, and one end of the long side of the two L-shaped pins passes through the two matching holes 5 and extends into the connector 4; the connector 4 is specifically a double-hole structure; and one end of the long side of the two L-shaped pins is parallel to the side wall of the connector 4 to ensure stable and effective plugging.

[0021] In the above design, this embodiment designs the connector 4 and the lamp housing 1 to be integrally injection molded, and uses two L-shaped pins, one end of which is welded on the PCB board 2 and the other end is inserted into the connector 4 to form a quick conduction. This not only allows the PCB board 2 to directly cooperate with the connector 4, eliminating the wiring harness between the PCB board 2 and the connector 4, overcoming the problem of short life of the wiring harness, but also eliminates the matching structure between the lamp housing 1 and the connector 4, thereby making the overall structure lighter and more compact, and the structure is simple, easy to assemble, and can save costs.

[0022] In addition, in order to improve the strength of the connector 4, the thickness of the connection between the lamp housing 1 and the connector 4 in this embodiment is greater than the thickness of other positions of the lamp housing 1. In addition, the integrated design of the connector 4 and the lamp housing 1 can extend the service life of the connector 4, making it less likely to be damaged or broken, and at the same time having higher safety performance.
