AI Technical Summary

Technical Problem

Existing leaky cable connectors are prone to elastic fatigue under long-term vibration, temperature cycling, or external tension, which can cause the front and rear shells to loosen, shift, or rotate relative to each other, affecting the stability and reliability of the connection.

Method used

The system employs a housing structure comprising a front shell and a rear shell. The relative rotation between the front and rear shells is restricted by an interference fit and a limiting structure. A clamping structure is provided to radially clamp the outer conductor. Combined with a backstop structure and a seal, the stability and reliability of the connection are improved.

Benefits of technology

It improves the vibration resistance, torsion resistance and electrical stability of leaky cable connectors, ensures the coaxial continuity of signal transmission path, reduces the risk of loosening, and improves overall reliability and assembly efficiency.

Abstract

This invention provides a leaky cable connector, comprising an inner conductor assembly, an outer conductor, a housing structure, a limiting structure, and a clamping structure. The housing structure includes a front shell and a rear shell. The front shell includes a body and a first mating channel. The inner conductor assembly is inserted into the first mating channel and fixedly connected to the body. The rear shell includes radially spaced inner and outer sidewalls that form an insertion cavity, into which at least a portion of the front shell is inserted. The rear shell also includes a second mating channel, which communicates with the first and second mating channels and is used to pass through the outer conductor. The limiting structure includes a first limiting portion and a second limiting portion. The first limiting portion is disposed within the front shell, and the second limiting portion is disposed within the rear shell. The first and second limiting portions engage to limit relative rotation between the front and rear shells. A clamping structure is formed at one end of the inner sidewall near the front shell, and the second limiting portion is disposed within the clamping structure. The clamping structure is used to clamp the outer conductor.
