AI Technical Summary

Technical Problem

Existing metal-cased router antenna connector designs suffer from issues such as loose nuts, connector rotational wear, wire breakage, and complex assembly, making it difficult to meet the demands of high-performance and multi-scenario applications.

Method used

The structure adopts a combination of a shaped retaining ring and a tongue. The tongue of the metal shell and the annular groove of the antenna connector form a circumferential mechanical limit. Combined with the elastic fit between the shaped retaining ring and the retaining ring groove, axial fixation is achieved. The screw-in depth is limited by the threaded stop, forming a triple limit structure.

Benefits of technology

It improves the stability and assembly efficiency of the connection structure, extends the service life of the antenna, reduces maintenance costs, and is suitable for mass production.

Abstract

The utility model belongs to the technical field of router antenna connection, and discloses a detachable antenna connector structure of a metal shell router, which comprises a metal shell, an antenna connector, a special-shaped clamp spring and a detachable antenna. The metal shell is provided with a mounting hole with an insertion tongue; the antenna connector is of a stepped-shaft-shaped structure, the peripheral wall of the antenna connector is sequentially provided with a positioning platform, an annular clamping groove, a clamping spring groove, an external thread and a thread spigot in the axial direction, the diameter of the positioning platform is larger than the aperture of the mounting hole, and the annular clamping groove is used for containing the insertion tongue; the special-shaped clamp spring is clamped into the clamp spring groove and is matched with the inner wall of the mounting hole to limit the axial movement of the antenna connector; the detachable antenna comprises an antenna body and an antenna lower fixing part, the inner wall of the antenna lower fixing part is provided with an internal thread matched with the external thread, and the end of the antenna lower fixing part abuts against the thread spigot. According to the utility model, through combination of mechanical limiting and elastic fixing, stable connection and convenient assembly of the detachable antenna are realized, and the stability of the connection structure and the use reliability are improved.
