Novel leaky cable fixing clamp

Abstract

The invention relates to the technical field of cable fixing equipment, in particular to a novel leaky cable fixing clamp. The clamp comprises a bottom plate, a clamping base and an upper cover plateused for being clamped between the bottom plate and the clamping base, wherein the clamping base is fixed to the bottom plate, and the clamping base and the bottom plate are integrally formed; locating structures are arranged at the bottom of the clamping base, and each of the two side walls of the clamping base is provided with a plurality of saw teeth; and a kidney-shaped cavity is formed in themiddle of the upper cover plate, a plurality of barbs are arranged on the kidney-shaped cavity, and two baffles are arranged at the two sides of the upper cover plate respectively. According to the clamp, the structure and material are optimally designed, the structure of the clamp can better resist slipping and twisting and fix a cable, and the locating structures are arranged for controlling the field intensity leaking direction of the leaky cable; and the material is a Dupont high-strength material PA66 which has good resistance to high and low temperature, temperature change, dampness andheat, salt mist and solar radiation and also has good environmental friendliness, combustion properties and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of cable fixing equipment, in particular to a novel leaking cable fixing jig. Background technique [0002] For the GSM-R railway mobile communication system of the passenger dedicated line, the quality of the leaky cable installation fixture will directly affect the driving safety. As the speed of the train continues to increase, there will be a great test for the leaky cable installation fixtures installed inside and outside the tunnel. The leaky cable installation fixtures must meet the environmental needs of high-speed trains in terms of structure and performance; Cable installation and fixing fixtures can no longer meet the technical requirements of the high-speed environment for the spreader. The overall strength and stability of the existing fixture structure deviates during use, and the material is generally ordinary plastic, which cannot meet the working requirements of high and low temperature, cor...

As the speed of the train continues to increase, there will be a great test for the leaky cable installation fixtures installed inside and outside the tunnel. The leaky cable installation fixtures must meet the environmental needs of high-speed trains in terms of structure and performance; The cable installation and fixing fixture can no longer meet the technical requirements of the spreader in the high-speed environment. The overall strength and stability of the existing fixture structure deviate during use, and the material is generally ordinary plastic, which cannot meet the working requirements of high and low temperature, corrosion and other environments.
