The utility model belongs to the technical field of cable testing, and discloses a cable testing device. The cable testing device comprises a base, a flange piece, a limiting shaft and a conductive connecting piece, the flange piece is fixedly installed on the base, the limiting shaft is movably installed on the base and can move in the direction close to and away from the flange piece, the limiting shaft and the flange piece are used for clamping and fixing a to-be-tested cable, the to-be-tested cable is provided with an end section, and the conductive connecting piece is connected with the limiting shaft. The conductive connecting piece is connected to the base, and the conductive connecting piece can abut against the end section and is electrically connected with a conductor in the to-be-tested cable. According to the cable testing device, the cable to be tested can be conveniently fixed and abutted against and electrically connected with the conductor in the cable, the stripping process is avoided, the cable can be abutted against the conductor only by simple cutting, the detection efficiency is improved, batch detection by a single person is facilitated, the detection cost is reduced, meanwhile, the conductor can be prevented from being damaged in the stripping process, and the detection efficiency is improved. Therefore, the accuracy of the detection result is improved.

This utility model discloses a brake hose connector thread testing device, relating to the field of thread testing technology. It includes a testing frame, a hydraulic cylinder, a servo motor, a rotating shaft, and a thread testing plate. The hydraulic cylinder is fixedly installed on one side of the top of the testing frame, and the servo motor is installed at the bottom of the testing frame. A threaded rotating shaft is rotatably connected to the midpoint of the servo motor. The thread testing plate is installed above the rotating shaft and below the hydraulic cylinder. In this utility model, when the brake hose connector thread is being tested, a pressing device inside the thread groove automatically presses the connector thread, fixing it during testing and accurately positioning the thread. The connector thread penetrates the interior of the thread groove. The testing plate and thread testing plate allow for simultaneous testing of double-ended threads, saving testing time and improving testing efficiency.
