Connector of integral type adaptor cable

Abstract

The invention discloses a connector of an integral type adaptor cable. The connector comprises an inner conductor, insulating media and an outer conductor, wherein the inner conductor, the insulating media and the outer conductor are sequentially and coaxially distributed from the center; the tail of the inner conductor is coaxially provided with an inner core welding hole; the tail of the outer conductor is in a step shaft shape, the tail of the outer conductor is provided with a shielding layer welding pipe of a coaxial structure, and the inner diameter of the shielding layer welding pipe is matched with the outer diameter of a shielding layer of the cable. The connector is simple in structure, reliable in mechanical property, excellent in electrical performance, high in assembly efficiency, high in using rate of raw material, and high in one-time assembly percent of pass, has low intermodulation performance, and is suitable for mass production of cable assemblies.

Description

Technical field: [0001] The invention relates to an integral connector for connecting cables, in particular to an integral 7 / 16 connector for connecting RG402 cables. Background technique: [0002] At present, the 7 / 16 connector for mating RG402 cables generally adopts a split structure. like figure 2 It is a split structure, the specific operation is to first snap the jack 5 into the inner hole of the insulator 6, then pass the cable 9 through the hole at the tail of the rear seat 7, and weld the inner conductor of the cable to the jack 5 Put together, crimp the insulator 6 into the shell 8 using a special tool, crimp the back seat 7 and the shell 8 together again using a special tool, and finally use a resistance welding machine to weld the cable braid and the back seat 7 together , so as to produce the traditional split 7 / 16 connector cable assembly with RG402 cable. There are four major disadvantages in this method: first, the cost of the product is high. During the p...

Problems solved by technology

There are four major disadvantages in this method: first, the cost of the product is high. During the processing of the back seat 7 and the shell 8, repeated clamping, processing, and electroplating are required, and the consumption of raw materials is large, the processing is difficult, and the processing cycle is long. , the cost is high, the market price and cost advantage is small, and there is basically no market competitiveness; the second is that assembly is difficult: since the back seat 7 and the shell 8 are crimped with the cable 9, the cable 9 needs to be crimped during the crimping process. Careful protection is carried out, and the cable may be damaged if you are not careful; the third is that the index performance is poor, because on the path of electrical performance transmission, the rear seat 7 and the shell 8 adopt a split and crimped structure, which will inevitably lead to its contact surface. The contact resistance on the surface increases, which leads to an increase in the voltage standing wave ratio of the product, which reduces the signal transmission efficiency of the product, and the intermodulation performance of the product with the split structure is poor, and the low intermodulation performance of the product cannot be achieved, and the current market cannot be satisfied. Fourth, there are great potential safety hazards. Since the rear seat 7 and the outer shell 8 adopt a split structure, machining errors generated during the machining process are unavoidable, and in the production and assembly of products, due to long-term labor, labor will inevitably be brought. Fatigue, leading to hidden dangers of product leakage, virtual pressure, and unreliable crimping
