Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The swing of the RF coaxial cable assembly refers to the repeated bending movement of the cable assembly with one clamping fixed point as the center and another clamped fixed point around the center with a certain bending radius at a certain angle.

[0025] The length direction of the swing rod is the radial direction of its swing. In the length direction, the swing rod includes a top, a second end and a first end from top to bottom, wherei...

Abstract

The invention discloses a bending tester of a radio frequency coaxial cable assembly. The bending tester comprises a mounting rack, a movable end clamping beam and a fixed end clamping beam. The radio frequency coaxial cable assembly is clamped between the movable end clamping beam and the fixed end clamping beam. The bending tester is characterized in that the mounting rack is also provided with a rocker mechanism, which comprises an eccentric rotating part and a swing rod; a first end of the swing rod is rotatably connected to the mounting rack, and a first end of the swing rod is in swing connection with the eccentric rotating part; the movable end clamping beam is connected on the swing rod and swings synchronously with the swing rod; and the fixed end clamping beam is fixed on the mounting rack and positioned on the rotating axis of the first end of the swing rod. By the technical scheme, the finished product coaxial cable assembly can be tested and actual bending motion of the cable assembly can be simulated, and electrical performance of the cable assembly can be accurately detected.

Description

technical field [0001] The invention relates to cable testing equipment, in particular to a bending testing machine for 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. Since the performance parameters of the RF coaxial cable that transmits high-frequency signals are selected by testing the performance parame...
