Summary of the invention

Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of switching convenient, and cost low Splices cable mechanism.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this Splices cable mechanism includes from inside to outside inner wire, insulator and the shell of suit successively, wherein the two ends of inner wire have the large and small jack for the cable conductor insertion of different wire diameters, have many axial slits on the sidewall of this large and small jack, the large and small jack sidewall between adjacent axial slits all has outer male structure; The first swivel nut and the second swivel nut have been threaded respectively in the two-port of described shell, be respectively arranged with in the first swivel nut, the second swivel nut and swivel nut separately axially the first lining and second lining of butt mutually, and be respectively equipped with the flange collar that coordinates with the first lining inner port, the second lining inner port phase inclined-plane on the inwall at described shell two ends.

Preferably, have a plurality of pawls that match with described insulator on the lateral wall of the described inner wire of contiguous described little jack, can combine closely with insulator to guarantee inner wire.

In above-mentioned each scheme, with described little jack with the end the insulator end face on have cannelure, the impedance irregularity when plugging together with compensating cable heart yearn and inner wire.

Further improvedly be, and also have collocation structure on the insulator end of described large jack with end, realize impedance uniformity.

Further preferably, and have compensated loop on the outer casing inner wall of described collocation structure corresponding position, be used for regulating high frequency performance.

The outer male structure place of corresponding described little jack lateral wall has convex rank on described insulator mouth inner wall, flexible space when guaranteeing that heart yearn and inner wire plug together.

In order to improve the water resistance of changeover mechanism, be provided with the first sealing ring on the mouth inner wall of above-mentioned the first swivel nut and the second swivel nut.In like manner, at described the first swivel nut and the second swivel nut respectively and be provided with the second sealing ring between the shell oral area, in order to be useful in the comparatively abominable occasion of environment.

Compared with prior art, the utility model can utilize the jack of two different sizes on inner wire, can directly carry out socket connection for the cable of different wire diameters, thereby the utility model has been removed loaded down with trivial details that a plurality of coaxial radio-frequency connectors of existing needs transfer from, the cable of different wire diameters is directly transferred easily and quickly, and by means of the axial slits in inner wire two jacks and outer male structure, can increase the reliability of contact after Elastic Contact, to satisfy the requirement on electric performance after being electrically connected to, and also have simultaneously simple in structure, the advantage that cost is low.
