A kind of air conditioning function test fixture

Technical field

The utility model relates to checkout equipment technical field, particularly relates to a kind of air conditioning function test fixture.

Background technology

Need to test the PCB in air-conditioning in the production run of air-conditioning, test fixture is normally utilized to test, every money circuit board has a special test fixture in the prior art, cannot compatible many moneys circuit board with a test fixture, whenever having new air-conditioning products to put into production, all need the test fixture that Design and manufacture is special, increase front-end investment.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can the air conditioning function test fixture of the multiple various boards of general detection.

In order to realize above object, the technical solution adopted in the utility model is:

A kind of air conditioning function test fixture, comprise test fixture main body and interchangeable test needle plate, different test needle plate upper surfaces has different probe arrays, the test contact point one_to_one corresponding of its probe and circuit board to be tested; Different test needle plate lower surfaces has identical connectivity port in same position, described frock main body is provided with on relevant position one to one that connectivity port is to connect different test needle plates, and described connectivity port connects PG electromechanical testing circuit, stepper motor test circuit and power supply test circuit respectively.

Further, the electric control part of described test fixture main body is divided and is comprised single-chip microcomputer, PG electromechanical testing circuit, stepper motor test circuit, power supply test circuit, switch power module and display module, wherein said switch power module is connected with the power input port of single-chip microcomputer, described PG electromechanical testing circuit, stepper motor test circuit and power supply test circuit and single-chip microcomputer input/output port are bi-directionally connected, and described display module is connected with the output port of single-chip microcomputer.

The beneficial effects of the utility model are: in air conditioning function test fixture of the present utility model, have interchangeable test needle plate, probe array on test needle plate coordinates with the circuit board of tape test, test contact point one_to_one corresponding on its probe and circuit board, only need be placed on circuit board to be tested on needle plate with suitable position and probe just can be made to contact with contact one_to_one corresponding of trying.Different test needle plate lower surfaces has identical connectivity port on identical position, frock main body is then provided with connectivity port one to one on relevant position, make frock main body can be adaptive from different test needle plates, finally realizing test fixture can the function of the multiple various boards of general detection.
