Problems solved by technology

However, the tensile strength of this connection method is poor, and it is very easy to be torn off in an environment with strong vibration and impact, causing the cable to be disconnected and affecting normal use; Cut off a section to expose the aluminum foil layer. It is difficult to separate the braided layer and the aluminum foil layer. It is time-consuming and laborious to install the connector, and it may even damage the connector. More importantly, after cutting off the shielding layer and the outer protective sleeve , there is a gap at the connection between the insulation layer of the cable and the connector, so there will be electromagnetic leakage and the shielding efficiency will be reduced

Abstract

The invention discloses a compression-resistant type coaxial cable for improving a shielding effect, and a connection method thereof. The invention relates to the technical field of coaxial cable connection, in particular to the compression-resistant type coaxial cable and the connection method thereof. According to the compression-resistant type coaxial cable, a cable body is compressed and connected with a connector by means of a metal casing pipe provided with an elastic rubber sleeve, the compression-resistant type coaxial cable is suitable to be used in a strong vibration and shock environment, the compression joint strength is high, the tension resistance is good, the radial section of the metal casing pipe is a regular hexagon, no flash is formed after compression joint, the injection molding thickness of a protective injection molding layer is even, the shielding effect for the connector is good, the shielding performance of the coaxial cable is improved, the metal casing pipe further ensures that the coaxial cable is arranged at the dead centre of the connector after installation, can effectively eliminating point discharge, enables the stress to be distributed more evenly, can play a role of voltage equalizing ring so that an electric field at the joint is distributed to the peripheral grounding region, avoids the occurrence of corona discharge, and cannot cause any damage to the cable and the machine.

Description

technical field [0001] The invention relates to the technical field of coaxial cable connection, in particular to a pressure-resistant coaxial cable with improved shielding effect and a connection method thereof. Background technique [0002] As one of the important components for transmitting high-frequency electrical signals, coaxial cables are widely used in radio communication, microwave transmission, broadcast communication and other systems due to their excellent characteristics such as low high-frequency loss, strong shielding and anti-interference ability, and wide frequency bandwidth. Signal transmission lines between base station transmitters, receivers, radio communication equipment or in the high frequency field. Because copper has good electrical, mechanical and thermal properties, the coaxial cables widely used in the mobile communication industry are basically made of copper. Copper coaxial cables are relatively heavy, so there are high requirements for cable...
