Description

Technical Field

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

[0002] Connectors typically consist of terminals, a core, and a housing. During production, the core is first used to position the terminal assembly. Then, the core with the positioned terminal assembly is fed into an injection molding machine, where the connector housing is injection molded onto its outer surface. To ensure the core's positional accuracy in the injection mold, locating pins are usually provided on the core, while corresponding locating grooves are provided in the injection mold. While this solves the core positioning problem, a gap remains between the connector housing and the locating pins, which can affect the connector's airtightness.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a connector core structure to solve the above problems. Utility Model Content

[0006] The preferred technical solution is as follows: the glue core includes glue core one and glue core two, glue core one is used to position the vertical section of the L-shaped terminal, and glue core two is used to position the horizontal section of the L-shaped terminal.

[0007] The preferred technical solution is as follows: the first adhesive core is provided with a buckle groove arranged in the horizontal direction, and the second adhesive core is provided with a spring buckle arranged in the horizontal direction, and the spring buckle is matched with the buckle groove.

[0008] The preferred technical solution is as follows: the first rubber core is provided with a terminal hole one for the vertical section of the L-shaped terminal to pass through, and the second rubber core is provided with a terminal hole two for the horizontal section of the L-shaped terminal to pass through.

[0009] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0010] This utility model proposes a connector core structure. By setting an annular protrusion around the positioning post of the core, the molten plastic melts and bonds the annular protrusion with the connector shell during injection molding, thereby solving the problem of gaps between the positioning post and the connector shell that affect the airtightness of the connector. This solution has the characteristics of simple and ingenious structure, which can ensure the airtightness of the connector and is suitable for widespread application. Attached Figure Description
