Description

N-type nut-free quick-insertion type radio frequency coaxial cable assembly

Technical Field

The utility model relates to a cable subassembly field, concretely relates to formula radio frequency coaxial cable subassembly is inserted soon to N type nothing nut.

Background

Traditional N type is the threaded connection mode in the existing market, is convenient and need specialized tool to screw the nut during the use inadequately to consuming time and wasting force during the field test, a plurality of parts such as casing, jump ring, nut are needed in the subassembly assembly. Once the designer selects the material improperly, the elasticity of the clamp spring material is poor, so that the nut falls off, and in addition, the depth of a groove for mounting the clamp spring on the nut is not enough during processing, and the nut can slip off by slightly adding a moment during connection. The nut of brass material, along with the extension of test live time, the phenomenon that wearing and tearing can appear in the thread's thread, causes not to twist well when using, connects insecurely, with the phenomenon of test equipment contact failure. In order to prolong the service life, stainless steel nuts are required, which greatly increases the production cost.

Therefore, the N-shaped nut-free quick-insertion type radio frequency coaxial cable assembly is needed, a snap spring and a nut are omitted, parts are simplified, quick pulling and inserting are achieved, and efficiency is improved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a formula radio frequency coaxial cable subassembly is inserted soon to no nut of N type to solve the problem that proposes in the above-mentioned technical background.

In order to solve the above problem, the utility model provides a following technical scheme: an N-type nut-free quick-plug radio frequency coaxial cable assembly, comprising: casing and cable, the inner conductor is installed at the casing center, the cover has the insulator on the inner conductor, the cable has been welded in the inner conductor, the cable passes the casing and connects the welding, the cable center is equipped with cable center conductor, cable center conductor passes the insulating pad of establishing on the cable, be equipped with female head in the casing, female head and public first junction are equipped with the packing ring.

Preferably, the gasket is made of rubber.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses save jump ring and nut, reduced manufacturing cost, avoided the risk that the nut drops. In addition, for the workers with frequent test times of the test products, the time is greatly saved, and the efficiency is improved. The utility model discloses the structure has set up a packing ring in public first and female first junction, lets the terminal surface of public female head realize in close contact with to reach the zero clearance of terminal surface, it is more firm to connect between public first and the female head, can not cause contact failure's phenomenon, makes the contact performance also obtain great improvement, the utility model has the advantages of can improve the contact performance, realize pulling out fast and inserting, raise the efficiency.
