Structure for enhancing reliability of low-intermodulation quick-plug compatible connector

Abstract

Teh invention discloses a structure for enhancing reliability of a low-intermodulation quick-plug compatible connector, which comprises a shell and a contact sleeve pressed in the shell, wherein the contact sleeve comprises a guide chamfer, a contact sleeve interference fit surface, a riveting turning yielding surface and a pressing surface; through applying pressure to the pressing surface, the guide chamfer of the contact sleeve is pressed in the shell inwardly; the inner wall of the shell comprises a riveting turning port and a shell interference fit surface; the contact sleeve interference fit surface and the shell interference fit surface are in interference fit; and the riveting turning port is pressed and turned to the riveting turning yielding surface via a riveting turning tooling. Compared with the prior art, the structure has the beneficial effects that the shell and the contact sleeve are in interference fit, the riveting turning port of the shell is pressed and turned to the riveting turning yielding surface of the contact sleeve via the riveting turning tooling, the contact sleeve and the shell are integrated as a whole, and the contact sleeve after riveting turning can bear at least 800 N axial thrust, which is far beyond the thrust requirements on other structure parts of the connector.

Description

technical field [0001] The invention relates to a structure for improving the reliability of a low-intermodulation quick-plug compatible connector. Background technique [0002] In modern communication network base stations, a large number of radio frequency microwave components are used, of which radio frequency connectors occupy a large share, dominated by DIN type N type, all outer conductors adopt rigid contact, and the electrical performance index and intermodulation index are good, but need Threaded connection requires a lot of work and is inconvenient for field construction. [0003] A new type of connector that is suitable for field use and can be quickly connected came into being. It can realize screw thread and quick plug compatibility. The contact sleeve uses elastic contact pieces, which can be heat-treated to achieve elastic contact and meet the contact needs of the outer conductor. Because the contact sleeve is in the product Inside, the processing method and ...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved in the present invention is to provide a solution to the problem that the contact sleeve of the existing connector is easy to fall off, and to provide a solution to the problem of large discrete diameters of the contact sleeve, which can make the product qualification rate reach more than 99.5%, and can also reduce The matching tolerance accuracy between the shell and the contact sleeve further reduces the processing cost and improves the reliability structure of the low-intermodulation quick-plug compatible connector
