Coaxial cable connector with integrated outer conductor

Abstract

The invention discloses a coaxial cable connector with an integrated outer conductor, which comprises an inner conductor, an insulation medium, a supporting medium and an outer conductor coaxially arranged in turn from inside to outside; the tail part of the inner conductor is axially provided with a welding hole; a cable inner core is welded in the welding hole; the tail part of the outer conductor is integrally provided with a screening tube; and the cable outer conductor is crimped on the screening tube through a cable pressing tube. The coaxial cable connector with the integrated outer conductor is a cable assembly which has the advantages of quick processing, simple structure, simple and reliable connection, good price comparability and more superior and stable electric performance and is suitable for large batch production.

Description

Technical field: [0001] The invention relates to a coaxial cable connector with an integral outer conductor. Background technique: [0002] At present, split welding structures are generally used for coaxial cable connectors. Such as image 3 It is a separate welding structure. The specific operation is to first assemble the insulator 9 into the shell 7, then crimp the base 10 together with the shell 7 using special tooling, weld the inner conductor of the cable and the socket 8 together, and weld the The cable 14 with the socket 8 is inserted from the tail of the base, and the outer conductor of the cable 14 is punched together with the tail of the base 10 using a clamp 13, thereby producing a traditional split cable assembly. There are three major disadvantages in this method: first, the product cost is high, the split shell 7 and the base 10 are repeatedly clamped during processing, the processing is difficult, the processing cycle is long, the consumption of raw materia...

Problems solved by technology

There are three major disadvantages in this method: first, the product cost is high, the split shell 7 and the base 10 are repeatedly clamped during processing, the processing is difficult, the processing cycle is long, the consumption of raw materials is large, and the competitive advantage in the market is small; The electrical performance index of this kind of cable assembly is poor. After the shell 7 and the base 10 are processed and assembled separately, the overall coaxiality error will be too large, and the shell 7 and the base 10 after the separate process are crimped by interference fit. The contact resistance between them increases, and the increase of the two will have an adverse effect on the voltage standing wave ratio, resulting in an increase in the standing wave ratio; the third is that the mechanical performance index of the coaxial cable is poor, and it is composed of a fixed connection between the shell and the base For cable assemblies, structural parts are prone to mechanical fatigue failure after long-term work, resulting in unstable mechanical performance indicators of cable assemblies
