Welding-free quick-locking adjustable cable parameter testing device

Abstract

The invention provides a welding-free quick-locking adjustable cable parameter testing device. The welding-free quick-locking adjustable cable parameter testing device comprises a radio frequency connector, a connecting sleeve, a spring, a tail shell, a conical bearing and a bayonet screw; the radio frequency connector comprises a first outer conductor, an inner conductor, a medium, a medium guide sleeve and a second outer conductor, the inner conductor is fixedly arranged in the first outer conductor through the medium, the end part of the medium is provided with the medium guide sleeve, the medium guide sleeve is plugged by the medium and arranged in the second outer conductor, and the end part of the second outer conductor is provided with contacts and a plurality of groups of slots located between the contacts; a key groove is further formed outside the first outer conductor, a round clamping groove is formed in one end of the key groove, and the bayonet screw corresponding to the key groove is connected to the connecting sleeve; the tail shell is connected to the end of the connecting sleeve in an internal threaded manner, the conical bearing is assembled and connected into the tail shell, and a spring abutting against the end of the first outer conductor is further connected into the connecting sleeve. According to the invention, the rapid locking can be realized, the damage to the cable is smaller, and the stability and reliability are higher.

Description

technical field [0001] The invention relates to a detection and self-locking structure of a single-head component or a bare wire, in particular to a welding-free fast locking and adjustable testing cable parameter device. Background technique [0002] In the prior art, cable manufacturers and end users still have big defects in distinguishing the performance superiority of radio frequency cables, and the commonly used method is to use connectors to directly weld the two ends of the cable. This method can detect the cable The whole roll is good or bad, but it is impossible to test the component manufacturer after cutting it. Moreover, the cable needs to be cut after welding, and there are also problems such as slow test time. [0003] The cable connection composite structure of the patented short-tail coaxial radio frequency connector (notification number is CN110311270A) includes a hollow shell, a coaxial cable penetrating into the shell, and a metal braid for welding the co...

AI Technical Summary

Problems solved by technology

This invention uses welding to fix the metal braid layer, and uses compression to fix the stainless steel wire. On the one hand, it can avoid the problem of the outer support and tensile effect of the shielding layer caused by the stainless steel wire falling off, and prevent the connector from being further disconnected from the cable. Keep the overlapping between stainless steel wires to ensure its shielding effect and ensure the radio frequency performance of the product, but it still has the above-mentioned general technical problems, and its stability and reliability are also poor
