Test fixture

Abstract

The invention discloses a test fixture, comprising a fixed frame, wherein two sides of the fixed frame are connected with a lower pressure plate via guide rods, a plurality of lower pressure columns are arranged at the bottom the lower pressure plate, a cover closing pressure lever is arranged in the middle of the lower pressure plate, a quick clamp is arranged at the upper part of the cover closing pressure lever, a pressure handle is arranged at the upper part of the quick clamp, a high-voltage connecting wire is arranged on the lower pressure plate, a high-voltage input end is arranged at the end of the high-voltage connecting wire, a test plate is arranged below the lower pressure plate, a plurality of test pin groups are uniformly arranged on the test plate, the test pin groups are all connected with the high-voltage connecting wire, a safety alarm device for cutting off power is connected to the high-voltage connecting wire, a plurality of bearing columns are arranged on the test plate, and a spring is arranged in each bearing column. Compared with the prior art, the test fixture has the advantages of simple structure, convenience in operation and strong practicability, and can be used for effectively testing the voltage penetrability of insulators such as LED (Light Emitting Diode) copper substrates or metal substrates and the like; and by adopting the safety alarm device, the safety of equipment can be greatly improved, the text fixture is safe in use, the test result is accurate, and the test performance is reliable.

[0002] The word "fixture" is directly translated from Japanese Chinese characters. It is an appliance used to assist operations. Common fixtures include: automation equipment, tooling fixtures, test fixtures, SMT furnace fixtures, Precision parts, blades, DVD read heads, etc., are simply a kind of auxiliary production equipment on the production line. Test fixtures refer to instruments used for testing. There are many types of test instruments, and they have different structures according to different test requirements. Features, when conducting voltage penetration tests on insulators such as LED copper substrates or aluminum substrates, the assistance of test fixtures is required. In the prior art, the test fixtures are used for voltage penetration of insulators such as LED copper substrates or aluminum substrates. When in use, the structure is relatively complicated, and the use is not convenient enough. Because a high voltage is often generated during the test process, the safety performance of the traditional test fixture is not good. Aiming at the above problems, the present invention is specially designed to solve it.
