The invention relates to the test equipment technology field and especially relates to a high precision test fixture of a PCB circuit board. The fixture comprises a side plate, a positioning seat anda rotation shaft. The side plate is installed on one side of an upper portion of a cover plate. The side plate and the cover plate are connected through a welding mode. A positioning seat is arrangedin the middle of a front portion of the side plate. The side plate and the positioning seat are fixedly connected through a built-in bolt. A pressing rod is arranged in the middle of an internal portion of the positioning seat. The positioning seat is connected to the pressing rod in a pass-through mode through the rotation shaft. The pressing rod is arranged in the middle of an internal portion of a compaction seat, and the pressing rod is connected to the compaction seat in the pass-through mode through a first rotation shaft. The compaction seat is installed in the middle of an upper portion of a test bench, and the compaction seat and the test bench are connected through a welding mode. In the invention, through improvements in the structure, an existing technology is combined so thatthe fixture possesses advantages that test precision is high, operation is simple and fast during testing, the device can be dismounted and so on; problems and disadvantages in an existing device technology are solved; and the fixture is practical.
Description
technical field [0001] The invention relates to the technical field of testing equipment, in particular to a high-precision testing fixture for a PCB circuit board. Background technique [0002] The high-precision test fixture is the equipment for testing the PCB, which is used to detect the short circuit or open circuit of the blank PCB. The equipment for testing the semi-finished PCB is used to check whether the function of the semi-finished product is normal, and then assembled into a finished product after normal. [0003] Through observation, it is found that the existing test fixtures generally have the problems of low test accuracy, cumbersome operation during the test, and non-detachable devices, which bring certain limitations in the actual test operation. Therefore, how to provide a High-precision testing, simple and fast operation during testing, and high-precision testing fixtures with detachable PCB circuit boards have become important issues that need to be sol...
