Coaxial cable tension test method

Abstract

The invention discloses a coaxial cable tension test method. The two ends of a to-be-detected cable body are wound on the surfaces of mounting shafts on the two sides respectively; and a first sliding nut on the surface of the first rotating screw rod drives an adjusting rod to move relatively, so that the upper side of the adjusting rod drives adjusting gears to move oppositely, the distance between the adjusting gears is changed, and the purpose of stretching the cable body is achieved. 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 the test.

Description

technical field [0001] The invention relates to the technical field of cable tension test, in particular to a coaxial cable tension test method. 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 performing a tensile test on a cable, one of the displacement mechanisms of the general tensile test device moves, thereby affecting the test effect during the test, wasting test time, and the position of the cable to be tested cannot be adjusted according to the requirements during 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 reduce the fastening effect on the cable when stretching , thus affecting the accuracy of stretch data
