Abstract

The invention discloses a bending test device applied to a radio frequency coaxial cable assembly, and relates to the technical field of cable test equipment. The device comprises a supporting track part, movable clamping beams, a transmission mechanism, a mounting table, a driving motor and an eccentric rotating rod. Through the mode that the movable clamping beams in the two directions are relatively and horizontally close to each other, and a line clamping head rotates along a rotating part according to the stress change generated by bending of the radio frequency coaxial cable assembly for self-adaptive angle adjustment (equivalently, the shape change generated when the hand of a person pulls a linear or strip-shaped object is simulated), and when the radio frequency coaxial cable assembly is bent by an angle, the stress is not easy to concentrate at the fixed position of the line clamping head, thereby preventing the radio frequency coaxial cable assembly from being bent at the position of the line clamping head, and preventing the bending test from being influenced and the abrasion from occurring. Besides, the rotation range can be expanded or reduced to control the bending angle by adjusting the expansion and contraction of the eccentric rotation rod, so that the bending test requirements of the radio frequency coaxial cable assembly can be met, and the accuracy of the bending test can be improved.

Description

technical field [0001] The invention relates to the technical field of cable testing equipment, in particular to a bending testing device applied to radio frequency coaxial cable assemblies. Background technique [0002] In communication equipment, radar equipment and other electronic equipment, especially in military electronic equipment, various types of radio frequency coaxial cables are required to transmit high frequency signals. In some cases, the RF coaxial cable will be in the working state of repeated bending, that is, the cable is centered on one clamping fixed point, and the other clamping fixed point is repeatedly bent around the center at a certain angle with a certain bending radius sports. In the life cycle of the product, the RF coaxial cable is required to meet hundreds of thousands or even millions of times of repeated bending without breaking. [0003] Since the performance parameters of the RF coaxial cable that transmits high-frequency signals are sele...
