Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness and cable testing, and in particular relates to a high-voltage test bench with stable clamping. Background Art

[0002] With the rapid development of modern electronic information technology, the application of electronic equipment is becoming more and more extensive. Wire harnesses and cables are indispensable inside electronic equipment. Therefore, the development and use of wire harnesses and cables are also very important. After the wire harnesses and cables are produced and processed out of the production line, various inspection tests are required. One of the inspection tests requires the use of a high-voltage test bench. The high-voltage test bench is a process test instrument used in the field of mechanical engineering. It is used for lightning impulse, power frequency withstand voltage, loop resistance, and dielectric loss tests.

[0003] When the existing high-voltage test bench tests the wiring harness cables, the wiring harness cables are directly placed in the test area on the test bench surface. There is no fixed clamping mechanism for the wiring harness cables in the test area. When multiple wiring harness cables are tested, they are placed in a messy and disorderly manner, which is easy to cause confusion. For this reason, we propose a high-voltage test bench with enhanced stability. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a high-voltage test bench with stable clamping, including a test bench main body. The upper surface of the test bench main body has a test area, and a protective cover is fixedly installed at the test area position. The upper surface of the protective cover has an opening, and a protective door is hingedly installed at the opening position.

The end of the output shaft of the motor is fixedly connected to a bidirectional lead screw rotatably installed inside the bearing platform. Threaded plates are threadedly installed on the outer surfaces of the two threaded sections of the bidirectional lead screw. A connecting plate is fixedly installed on the upper surface of the threaded plate, and the connecting plate is slidably installed in a slideway opened on the upper surface of the bearing platform, and an upper mounting plate is fixedly installed at the top end of the connecting plate. A plurality of through rings are fixed on the upper surface of the upper mounting plate, threaded rods are threadedly installed on the through rings, a handle is fixedly installed at the top end of the threaded rod, and a clamping plate is rotatably installed at the bottom end of the threaded rod.

[0006] With the above scheme, by setting the bearing platform to cooperate with the bidirectional lead screw and the through rings, the relative movement of the two upper mounting plates is realized by the rotation of the bidirectional lead screw, and thus it can be applied to the test fixing and clamping of wire harness cables of different lengths.

[0014] As a preferred embodiment, a plurality of support guide rods are fixedly installed on the inner wall of the bearing platform, and the lower threaded plate is slidably installed on the outer surface of the support guide rods.

[0015] With the above solution, the support guide rods can support the lower threaded plate, so that the lower threaded plate is not prone to tilt and shake during movement, improving the movement stability.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] This high-voltage test bench with stable clamping is used in cooperation with the bearing platform, the bidirectional lead screw and the through ring. By rotating the bidirectional lead screw, the relative movement of the upper mounting plates on both sides is realized, and thus it can be applied to the test fixation and clamping of wire harness cables of different lengths.
