Low-cost radio frequency coaxial cable connector

Abstract

The invention discloses a low-cost radio frequency coaxial cable connector which comprises a screw barrel, a sealing part, clamping rings and an outer conductor. A through hole in a barrel shape is formed in the middle of the outer conductor, a radio frequency coaxial cable is inserted into the through hole and fixedly connected with the outer conductor, a concave ring is arranged on the outer surface of the outer conductor, a hole is formed in the middle of the screw barrel, the outer conductor is arranged in the hole, a groove ring is arranged on the hole wall of the screw barrel, and the groove ring corresponds to the concave ring of the outer conductor. The clamping rings are arranged in the concave ring and the groove ring to limit and fix the screw barrel and the outer conductor. The sealing part is arranged between the outer surface of the outer conductor and the inner wall of the hole of the screw barrel to seal the outer conductor and the screw barrel. The low-cost radio frequency coaxial cable connector is ingenious design, simple in structure and convenient and quick to assemble.

Description

technical field [0001] The invention relates to a radio frequency coaxial cable connector, in particular to a low-cost radio frequency coaxial cable connector. Background technique [0002] A radio frequency coaxial connector is a component mounted on a cable or installed on an instrument as a component for transmitting electrical connections or separations. RF coaxial connectors have the characteristics of long life, superior performance, and reliable connection. They are widely used to connect RF coaxial cables in RF loops of microwave equipment and digital communication equipment. The RF coaxial connector is mainly composed of an outer conductor, an insulator and an inner conductor; at present, the existing RF coaxial cable connector is composed of an outer conductor, an insulator and an inner conductor, and its assembly method is as follows ( Figure 4 , Figure 5 ): [0003] 1. Put the seal ring 13 and snap ring 14 into the outer conductor 16; [0004] 2. Install the...

AI Technical Summary

Problems solved by technology

[0008] At present, the insulator material of RF coaxial cable connectors is polytetrafluoroethylene, which has a high raw material price and a large thermal expansion coefficient, which makes it difficult to process RF coaxial connectors, unstable product performance, and high cost.

At the same time, the inner conductor of the RF coaxial connector is made of copper, the price of its raw materials is also high, and there are many processing procedures, and the inner conductor plating process is complicated.
