Male joint of coaxial cable connector

Abstract

The invention discloses a male joint of a coaxial cable connector, which comprises a central conductor, an insulator and an outer conductor, wherein the front end part of the central conductor is provided with a conical protrusion, while the rear end part is a cylinder used for inserting an inner conductor of coaxial cable; the insulator is provided with a through hole; the outer conductor is divided into a front section, a middle section and a rear section; the front section is transited to the middle section through a first step; the first step is provided with a compensating ring; the internal diameter of the middle section is matched with the external diameter of the insulator; the internal diameter of the rear section can be inserted by the coaxial cable; the internal surface of the middle section is transited to the internal surface of the rear section through a second step; the second step is used for axially positioning the insulator; the internal diameter of the through hole of the insulator is matched with the external diameter of the cylinder at the rear end part of the central conductor; and one part of the cylinder at the rear end part of the central conductor is inserted into the through hole of the insulator. The male joint meets the conventional technical standards; the insulator can be directly plugged from a plugging end; one part of the cylinder of the central conductor is inserted into the through hole of the insulator and is stably fixed, so, the male joint is more convenient to assemble.

Description

technical field [0001] The invention relates to cable connector technology, in particular to a coaxial cable connector male joint. Background technique [0002] Coaxial cables are widely used in various signal transmissions, especially video signal transmissions. Different cables need to be effectively connected in order to effectively transmit signals and avoid signal attenuation. For this reason, various coaxial cable connection devices have been used in the prior art. [0003] Such as figure 1 A coaxial cable connector of the prior art shown is a schematic cross-sectional view along the axial direction after the male connector and the female connector are inserted. The central conductor 21, the middle layer surrounding the central conductor 21 is an insulator 22, the outer layer is an outer conductor 23, and an outer nut 24 sleeved on the outer conductor 23. The female joint includes three layers of inner, middle and outer ring structures, the inner layer is the centra...

Problems solved by technology

[0016] However, in use, the inventors found that the center conductor 31 of the improved male connector is only fixed by the center conductor of the coaxial cable inserted therein, requiring soldering

However, the welding is limited by the short length and the welding space, and the operation is difficult. It is easy to burn the insulator at high temperature, and after welding, it is easy to be subjected to cable vibration, and the center conductor of the cable moves slightly, which will cause the central conductor of the joint to break. Unstable, under high-frequency signals, various signals cannot be transmitted normally, and the intermodulation performance is very poor, so it is necessary to further improve
