Description

Technical Field

[0001] This utility model relates to connector manufacturing technology, specifically to a printed circuit board adapter connector. Background Technology

[0002] Automotive PCBs (printed circuit boards) not only provide a stable support for electronic components but also serve as a crucial bridge for transmitting electrical signals, making them a core component of modern automotive electronic equipment. Soldered connectors on PCBs are not very practical; they cannot achieve the required seal when used alone with the housing, and flexible hose connectors are inconvenient for installation. Currently, some manufacturers are integrating adapters into the housing, which increases both the production and maintenance costs of the housing. Utility Model Content

[0003] The purpose of this invention is to provide a printed circuit board adapter connector that is easy to connect and install.

[0004] The technical solution of this utility model is: a printed circuit board adapter connector for fixing on a printed circuit board housing, including an adapter housing, a male terminal, an assembly housing, a female terminal, and a seal. The outer ring of the middle part of the adapter housing is provided with a fixing part that connects to the printed circuit board housing. One end of the adapter housing located below the fixing part is disposed inside the printed circuit board housing and is provided with a socket for the assembly housing to be inserted. The other end is located on the periphery of the printed circuit board housing. The male terminal is disposed inside the adapter housing. One end of the assembly housing is inserted into the adapter housing, and the other end is inserted into the printed circuit board. The female terminal is disposed inside the assembly housing.

[0005] A further technical solution involves providing a sealing groove at the bottom of the fixing part, with the sealing element embedded within the sealing groove.

[0006] A further technical solution involves providing a fixing hole on the fixing part for fixed connection, with an iron ring embedded in the fixing hole.

[0007] In a further technical solution, both the adapter housing and the male terminal are inverted L-shaped. The adapter housing has a slot for the male terminal to pass through, and the bottom end of the male terminal is inserted into the female terminal to form a connecting assembly.

[0008] The beneficial effects of this utility model are:

[0009] This utility model has a simple structure, is easy to install, reduces the maintenance cost of printed circuit board adapters, ensures the sealing of the connection between the adapter housing and the printed circuit board housing, and ensures the docking between the connection component composed of female and male terminals and the printed circuit board. It has strong applicability. Attached Figure Description

[0012] Among them, 1. Adapter housing, 2. Male terminal, 3. Assembly housing, 4. Female terminal, 5. Fixing part, 6. Sealing groove, 7. Sealing element, 8. Iron ring, 9. Printed circuit board, 10. Printed circuit board housing. Detailed Implementation

[0013] The present invention will be further illustrated and understood below through non-limiting embodiments.

[0014] like Figure 1-2 As shown, this utility model provides a printed circuit board (PCB) adapter connector with good sealing performance and high practicality, used for fixing to a PCB housing 10. This utility model includes an adapter housing 1, a male terminal 2, an assembly housing 3, a female terminal 4, and a sealing element 7. The outer ring of the middle part of the adapter housing 1 has a fixing part 5 that connects to the PCB housing 10. After the utility model is inserted into the PCB housing 10, the fixing part 5 abuts against the end face of the PCB housing 10. The fixing part 5 has a fixing hole for fixed connection, and an iron ring 8 is embedded in the fixing hole. The fixing part 5 and the PCB housing 10 are fixedly connected by a screw passing through the iron ring 8. A sealing groove 6 is provided at the bottom of the fixing part 5, and the sealing element 7 is embedded in the sealing groove 6.

[0015] Both the adapter housing 1 and the male terminal 2 are inverted L-shaped. The adapter housing 1 has a slot for the male terminal 2 to pass through. The bottom end of the male terminal 2 is inserted into the female terminal 4 to form a connecting assembly. One end of the adapter housing 1 located below the fixing part 5 is located inside the printed circuit board housing 10 and has a socket for the assembly housing 3 to be inserted. The other end is located on the periphery of the printed circuit board housing 10. The male terminal 2 is located inside the adapter housing 1. One end of the assembly housing 3 is inserted into the adapter housing 1, and the other end is inserted into the printed circuit board 9. The female terminal 4 is located inside the assembly housing 3.

[0016] During installation, the male terminal 2 is injection molded into the adapter housing 1, and the fixing part 5 is injection molded to form an integral structure with the adapter housing 1. The iron ring 8 is injection molded into the adapter housing 1, and then the sealing part 7 is assembled onto the adapter housing 1 to form an adapter plug. The female terminal 4 is pressed into the assembly housing 3 by equipment to form a board socket for the printed circuit board 9. In use, the assembly housing 3 and the female terminal 4 are combined to form a board socket and soldered onto the printed circuit board 9, which is then installed inside the printed circuit board housing 10.

[0017] In subsequent use, simply insert the adapter plug, which consists of adapter housing 1, male terminal 2, and sealing element 7, into the board socket. Finally, use screws to pass through the iron ring 8 to fix adapter housing 1 and printed circuit board housing 10. The sealing element 7 forms a seal between adapter housing 1 and printed circuit board housing 10 to provide waterproofing.

[0018] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
