Description

A kind of integrated cable connector

Technical field:

The utility model relates to a kind of integrated cable connector.

Background technology:

At present, generally adopt split-type structural for cable connector.As Fig. 2 is split-type structural, concrete operations are first insulator 6 to be installed in shell 7, again back seat 8 is crimped onto in shell 7, after again the inner wire of cable 10 and jack 9 being welded, from the afterbody of back seat 8, penetrate, use resistance welder that cable and back seat 8 is welded together, thereby produce traditional cable assembly.There are three large drawbacks in this mode: the one, and the cost of product is high, shell 7 is all to adopt metal to be processed, electroplate with back seat 8, in the process realized, need clamping, processing, plating repeatedly, raw materials consumption is more, and difficulty of processing is large, process-cycle is longer, cost is high, and the Costco Wholesale advantage in market is little, does not substantially have commercioganic competitiveness.The 2nd, the index poor performance, on the path in the electrical property transmission, shell 7 adopts the mode of split, crimping to be combined with back seat 8, must cause the contact resistance on its contact-making surface to increase, thereby cause the voltage standing wave ratio of product to increase, reduce the effectiveness of product; The 3rd, consistency is poor, and because shell 7 and back seat 8 adopt split, crimping structure, the mismachining tolerance that machining process produces is unavoidable, discontinuity in the time of must causing shell 7 with back seat 8 crimping, thereby the consistency variation of product while causing producing in batches.

Summary of the invention:

For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of integrated cable connector, is a kind of simple in structure, reliable in mechanical performance, and electric property is superior, and packaging efficiency is high, with low cost, is suitable for the cable assembly of producing in enormous quantities.

The utility model technical solution problem adopts following technical scheme:

A kind of integrated cable connector, it comprises:

The inner wire, matched media, dielectric and the outer conductor that from center, outwards coaxially arrange successively, the front end of described outer conductor is the Step Shaft structure, and the front end at described outer conductor is provided with the screen welded pipe be structure as a whole with outer conductor.

Design feature of the present utility model also is:

The excircle direction of described inner wire is provided with the spacing scrobicular ring of a circle, correspondingly, the internal chamber wall of described matched media is along being circumferentially with a circle position limiting convex ring, and described spacing scrobicular ring and position limiting convex ring form the convex-concave ring structure and realize the axial limiting to inner wire and matched media.

The internal chamber wall of described outer conductor, along being circumferentially with a circle positive stop lug boss, is provided with a circle limited impression on the excircle direction of described dielectric; Described positive stop lug boss and described limited impression are realized the axial location to outer conductor and dielectric.

The end periphery of described matched media is along being circumferentially with a delineation position groove, and correspondingly, the internal chamber wall of described dielectric is along being circumferentially with a delineation position boss, and described detent and described positioning boss are realized the spacing of matched media and dielectric with fixing.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Cable connector of the present utility model, the front end integral type of outer conductor is provided with the screen welded pipe, screen welded pipe and outer conductor body are the Step Shaft shape, and the screen welded pipe is thinner, and the screen external diameter of its internal diameter and cable is basically identical, this has cancelled the back seat of existing cable connector in structure, simplify the processing technology of product, when shortening the product machining processes, shorten the processing duration of product, reduce in the product machining process and waste, improve raw-material utilization rate; The integral structure of outer conductor, be conducive to reduce the contact resistance between the metalwork electrolysis, thereby reduce the voltage standing wave ratio of product, the effective power transmission of improving product; Stability is superior, because outer conductor is the integral type structure, effectively evades the potential safety hazard that the crimping that the crimping of outer conductor two-part brings is not firm, not in place, leak crimping; All adopt the fixed form of convex-concave structure between inner wire, matched media, dielectric and outer conductor, effectively guarantee the Stability and dependability between all parts; Between inner wire, outer conductor and radio frequency cable, adopt the mode of welding to carry out, in the contact resistance that reduces product, effectively the adaptability of improving product to environment, evade the oxidation risk of product under long-term erosion environment, the oxidation resistance of improving product.
