AI Technical Summary

Technical Problem

The existing coaxial connectors require cumbersome and time-consuming procedures for adjusting the position of cables and components and solder joints on site, and the product performance cannot be guaranteed, which can easily lead to unstable contact problems.

Method used

A coaxial connector and its replaceable components are provided. By ultrasonically welding the second inner conductor to the first inner conductor at the factory and crimping the intermediate connecting sleeve to the first outer conductor, a standardized replaceable component is formed. On-site maintenance only requires replacing this component.

Benefits of technology

It simplifies on-site maintenance operations, ensures welding quality and impedance performance, reduces resource waste, saves expensive on-site service time and travel costs, and improves maintenance efficiency and product performance consistency.

Abstract

The invention relates to a coaxial connector and a replaceable assembly thereof. The replaceable assembly comprises a cable, a second inner conductor and a middle connecting sleeve. The cable includes a first inner conductor and a first outer conductor. The first outer conductor is sleeved outside the first inner conductor and is insulated from the first inner conductor. And the second inner conductor is welded with the first inner conductor. The middle connecting sleeve is sleeved outside the first outer conductor and is electrically connected with the first outer conductor, and the middle connecting sleeve is detachably sleeved inside and fixed on the connector main body and is electrically connected with the connector main body. According to the coaxial connector and the replaceable assembly thereof, when maintenance is needed, the replaceable assembly is directly replaced, the connector main body is reserved and reused, and resource waste is reduced. The replaceable assembly is a standardized component, and in the field maintenance process, the replaceable assembly can be replaced, so that expensive field service time, travel cost and potential loss caused by improper maintenance can be saved.
