Coaxial cable tension test device

Abstract

The invention discloses a coaxial cable tension test device which comprises a shell, a control panel is installed at the bottom of the surface of the shell, a first driving motor is installed in the middle of the bottom in the shell, a first transmission rod is installed at the power output end of the first driving motor, and a transmission gear is installed at the top end of the first transmission rod. Bearing shells are symmetrically installed on the two sides in the shell, first rotating lead screws are rotationally installed at the positions, close to the interiors of the bearing shells, of the two sides in the shell, and first sliding nuts are movably connected to the surfaces of the first rotating lead screws. A second driving motor is started, a second transmission rod rotates through a crawler belt and a first mounting rod, so that the first mounting rod drives a cable body to move through a mounting shaft, the position needing to be stretched is changed, the stretching part of the cable body can be adjusted according to requirements during testing, time and labor are saved, and therefore, the stretching efficiency of the cable body is improved during an experiment.

Description

technical field [0001] The invention relates to the technical field of cable tension test, in particular to a coaxial cable tension test device. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has The characteristics of internal electrification and external insulation require a series of tests before the cable is used. The tensile testing machine is also known as the universal material testing machine. Universal testing machine is a mechanical testing machine used for static load, tension, compression, bending, shearing, tearing, peeling and other mechanical performance tests of instruments and equipment for various materials. It is suitable for plastic sheets, pipes, Various physical and mechanical performance tests of profiled materials, plastic ...

AI Technical Summary

Problems solved by technology

[0003] When the tensile test is performed on the cable, one of the displacement mechanisms of the general tensile test device moves, which affects the experimental effect during the test, wastes the test time, and cannot be adjusted according to the requirements when performing the tensile test. , because the moving cable is cumbersome, which affects the stretching time and reduces the stretching efficiency. When used for a long time, the fastening mechanism of the general tensile test device will fatigue, and then the fastening effect on the cable will be reduced during stretching. , thus affecting the accuracy of stretch data
