Solder-free fast locking adjustable test cable parameter device

Abstract

The invention provides a welding-free fast-locking adjustable test cable parameter device, comprising a radio frequency connector, a connecting sleeve, a spring, a tail housing, a conical bearing and a bayonet screw; the radio frequency connector includes a first outer conductor, an inner Conductor, medium, medium guide sleeve, second outer conductor, the inner conductor is fixed in the first outer conductor through the medium, the end of the medium is provided with a medium guide sleeve, and the medium guide sleeve is sealed by the medium and arranged in the second outer conductor , the end of the second outer conductor is provided with contacts and multiple groups of slots located between the contacts; the first outer conductor is also provided with a keyway, one end of the keyway is provided with a circular slot, and the connection sleeve is connected with a corresponding keyway. The bayonet screw, the end of the connecting sleeve is internally threaded with the tail housing, the tail housing is assembled and connected with a conical bearing, and the connecting sleeve is also connected with a spring abutting against the end of the first outer conductor, the present invention can not only realize quick locking It is tight, and the damage to the cable is less, 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
