Technical Field

The utility model relates to the technical field of communication cable matching and connection, in particular to a radio frequency cable rapid test connector.

Background

The radio frequency coaxial cable assembly mainly comprises a radio frequency coaxial cable and a matching connector, is widely applied to radio equipment, electronic instruments and various equipment, is mainly used for transmitting radio frequency signals, and is used for connecting various functional modules to form a complete system. In commercial applications, radio frequency coaxial cable assemblies are increasingly in demand, while cost is increasingly more tightly controlled. Therefore, how to manufacture the cable assembly quickly and efficiently in the production and manufacture of the radio frequency coaxial cable assembly is very important.

In the process of testing the radio frequency cable in the center of the prior art, the connecting cable and the matching connector need to be frequently disassembled, the workload is very huge, the process of installing and disassembling the existing connector is more complicated, and the testing efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art, and provides a radio frequency cable quick test connector.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a radio frequency cable tests connector fast, includes main part, insulator, swivel nut and central needle, the main part body has the cavity that switches on both ends face all around, insulator, swivel nut and central needle all set up in the cavity, the insulator parcel is in the outside of central needle, both ends all are provided with the preformed hole that is used for installing central needle around the insulator, the central needle passes through the insulator and keeps apart with the main part is insulating, the inside swing joint of main part has the compression sleeve, be equipped with the internal thread on the inner wall of main part, cooperation main part is provided with the external screw thread on the swivel nut.

Preferably, the material of the main body is brass.

Preferably, the insulator is made of polytetrafluoroethylene.

Preferably, the material of the central needle is beryllium copper.

Preferably, the central needle is an elastic probe.

Compared with the prior art, the utility model has the beneficial effects that: insert the inside of main part with the one end of radio frequency cable at first, because the center needle is elastic probe, good elasticity expansion performance has, can be automatic and cable contact, rotate the swivel nut again, the screw-thread fit through swivel nut and main part makes and compresses tightly the cover and compress tightly the cable, and then realize the effect of fixed cable, then detect the cable with the main part connection on the test instrument, detect and accomplish the rear direction and rotate the swivel nut, and then can make and compress tightly cover and cable separation, can take out the cable that detects the completion, moreover, the steam generator is simple in structure, and convenient for operation, and the test efficiency of radio frequency cable is improved.
