Abstract

A combined type coaxial cable connector comprises an inner conductor which is connected with an inner wall of an outer casing through an insulation support. The outside of the outer casing is connected through a first connection mechanism, a second connection mechanism and a third connection mechanism, an outer conductor penetrates through an insulator to be fixed on the inner wall of the end head of the outer casing through a nut, the inner conductor of the connector and an inner conductor of a cable adopt a crimping method to be connected, simultaneously holes are arranged on the connector, soldering tin is added to heat at the high temperature to prevent a crimping portion from oxidation due to that fact that metal is contacted with the surface for a long time and to prevent resistance from adding, and the soldering tin is unleaded soldering tin and has a high melting point. The connector adopts a mode combining mechanical crimping and welding, so that the combined type coaxial cable connector can effectively achieve connection under a high temperature environment, and can avoid surface oxidation of contact portions and prevent the resistance from adding.

Description

A kind of combined type coaxial cable connector

Technical field

The utility model relates to the cable connector field, is specifically related to a kind of combined type coaxial cable connector.

Background technology

Existing cable connector inner wire generally adopts scolding tin to be connected with the inner wire of cable, and the outer conductor of connector also adopts scolding tin to be connected with the outer conductor of cable, connects owing to can under hot environment, carry out cable; The normal scolding tin fusing point that adopts is lower, so scolding tin connects and have certain drawback, in addition; Also have and adopt the crimping mode to connect; But can cause resistance to become big at long-term Metal Contact surface oxidation, influence the transmission of signal.

Summary of the invention

For fear of the weak point of prior art, the utility model provides a kind of coaxial cable connector of combined type, adopt this connector can satisfy under hot environment and use, can avoid contact surface resistance excessive simultaneously.

In order to achieve the above object, the technical scheme taked of the utility model is:

A kind of combined type coaxial cable connector comprises inner wire 1, and inner wire 1 supports 3 through insulation and is connected with the inwall of shell 5; The outside of shell 5 is connected with the 3rd bindiny mechanism 6 through first bindiny mechanism 4, second bindiny mechanism 8; Outer conductor 2 is fixed on the inwall of shell 5 terminations through insulator through nut 7, and connector inner wire 1 adopts the method for crimping to be connected with cable inner conductor, the perforate in the junction simultaneously; Add scolding tin, heat.

Described scolding tin is Pb-free solder.

What the utility model adopted is mechanical crimping and the mode that welding combines, and both can effectively must realize connecting under the hot environment, can avoid contact site surface oxidation resistance to become big again.

Description of drawings

Accompanying drawing is the structural representation of the utility model.

Embodiment

A kind of combined type coaxial cable connector comprises inner wire 1, and inner wire 1 supports 3 through insulation and is connected with the inwall of shell 5; The outside of shell 5 is connected with the 3rd bindiny mechanism 6 through first bindiny mechanism 4, second bindiny mechanism 8; Outer conductor 2 is fixed on the inwall of shell 5 terminations through insulator through nut 7, and connector inner wire 1 adopts the method for crimping to be connected with cable inner conductor, the perforate in the junction simultaneously; Add scolding tin; Heat prevents the long-term Metal Contact surface oxidation in crimping position with this, and it is big that resistance becomes.

Described scolding tin is Pb-free solder, and its fusing point is higher.

What this connector adopted is mechanical crimping and the mode that welding combines, and both can effectively must realize connecting under the hot environment, can avoid contact site surface oxidation resistance to become big again.

The above; Only be the embodiment of the utility model; Be not that the utility model is done any restriction, everyly any simple modification that above embodiment did, change and equivalent structure changed, all still belong in the protection range of the utility model technical scheme according to the utility model technical spirit.
