Cable detecting equipment

Abstract

The invention relates to cable detecting equipment. The cable detecting equipment comprises a rotary bracket, a clamp for clamping a first end of a cable to be detected, a guide mechanism for positioning and guiding the cable to be detected on the rotary bracket, a load device for drawing and tensioning the cable to be detected, and a driving mechanism for driving the rotary bracket to rotate around a rotation center. The load device is arranged on the rotary bracket and is relatively fixed with the rotary bracket in the horizontal direction; and the gravity line center of the load device is overlapped with the rotation center of the rotary bracket. According to the cable detecting equipment provided by the invention, the gravity center line of the load device is designed to be overlapped with the rotation center, so that the phenomenon of switching the load device in a detecting process can be avoided on the root. Therefore, the limitations of a rotation angle and a speed can be removed, and the accurate detection result can be ensured.

Description

technical field [0001] The invention relates to the technical field of product detection, in particular to a cable detection device. Background technique [0002] Cables such as power cables and data cables of electronic products need to undergo various tests during design and production to ensure safe use. Among them, there is a cone test for testing the conical bending resistance of cables. [0003] An existing cable detection device for cone detection such as figure 1 and figure 2 As shown, it includes a rotating disk 100 with a wire passing hole 101 near the periphery, and a clamp 200 located directly above the center of the rotating disk 100 . When testing, the plug 301 at one end of the cable 300 is clamped and fixed by the clamp 200, and the other end passes through the wire hole 101 on the rotating disk 100 and is tightened by a load such as a weight 400, so that the cable The wire has a predetermined angle with the vertical direction, usually 45°, and then the r...

Problems solved by technology

[0004] However, the above-mentioned existing cable detection equipment has the following defects when testing the conical bending resistance of the cable: 1. According to the relevant testing standards, when doing the cone detection, the cable needs to be subjected to a constant tension in the direction of the predetermined angle, and In the actual testing process, in addition to gravity and cable tension, the weight of the pulling cable is also subjected to the centrifugal force generated during rotation, which causes the weight to swing during the testing process, and also makes the test unable to provide accurate results. Instability also limits the rotation angle and speed of the cone detection; 2. Since one clamp arm of the fixture 200 is fixed, the other clamp arm performs relative movement to clamp and fix the plug 301. When the shape of the plug is irregular, it cannot be guaranteed that the connection between the wire and the plug is always at the center of rotation, so that the cone angle is not constant during the test
