One end of the cable to be detected is clamped on the positioning plate, the other end of the cable is fixed on the cable fixing mechanism, and the wire pressing clamp pushes the fixing seat to move on the frame, so that the pull rod on the positioning plate slides on the fixing seat relatively, the spring is compressed, and whether the sliding load of the wire clamp on the cable meets the requirement is judged through the compression ratio of the spring.
In order to clamp and loosen the cable quickly and conveniently, the cable fixing mechanism comprises clamping plates which are arranged oppositely at intervals, and the two clamping plates which are arranged oppositely are relatively close to or far away from each other through screws. The two clamping plates can clamp or loosen the cable rapidly through the control screw.
The beneficial effects of the invention are as follows: when the E-type contact wire electric connection testing machine is used, one end of a cable needing to be detected is clamped on the positioning plate, the other end of the cable is fixed on the cable fixing mechanism, the wire pressing pliers push the fixing seat to move on the rack, so that the pull rod on the positioning plate slides relatively on the fixing seat, the spring is compressed, whether the sliding load of the wire clamp on the cable meets the requirement is judged through the compression ratio of the spring, and meanwhile, the nut is rotated, so that one end of the pull rod compresses the spring, the sliding load required by the cable is obtained, the detection is faster and more convenient, the problem that common equipment cannot perform multiple load tests or test inaccuracy when the existing testing device detects the sliding load between the wire clamp is avoided, the equipment is provided with detection accurate matching, but the price of the equipment is relatively expensive, and the use cost is increased is solved.
