Electronic product board card conduction test device

Abstract

The invention discloses an electronic product board card conduction test device which comprises a base. A board card socket is arranged in the rear end of the top of the base. Limiting slots are symmetrically arranged on both sides of the board card socket at the top of the base. A limiting plate is slidably connected with the inside of each limiting slot. A return spring is fixedly arranged between one end of the inside of each limiting slot and a limiting plate. A lithium battery is embedded in the front end of one side of the base. A transformer is arranged on one side in the base. A knob switch is arranged on the upper end of the transformer at the top of the base. An LED display screen is embedded in the middle of the top of the base. A relay protector connected in parallel with the knob switch is embedded in the front end of the top of the base. A clamp slot is arranged on the other side of the top of the base. A test pen is clamped in the clamp slot. The device has the advantages of simple and reasonable structure design, convenient operation, convenient disassembly and assembly, low test cost, good effect, time and labor saving, safety, stability and wide application range,and is favorable for promotion and popularization.

Description

technical field [0001] The invention belongs to the technical field of card board testing, and in particular relates to a device for testing continuity of electronic product board cards. Background technique [0002] The board card is a printed circuit board, referred to as PCB board, which has a ferrule when it is produced, and can be inserted into the slot of the main circuit board (main board) of the computer to control the operation of hardware, such as monitors, acquisition cards and other equipment. , after installing the driver, the corresponding hardware functions can be realized. Most of the existing boards are directly installed on electronic products to test whether they are connected, which is troublesome to disassemble, time-consuming and labor-intensive, and the test cost is high, which is not conducive to wide promotion and popularization. Contents of the invention [0003] The purpose of the present invention is to provide a kind of electronic product boar...
