Description

LED display screen aging test fixture

Technical Field

The utility model belongs to fixed tool field, in particular to a tool for LED display screen aging testing.

Background

The aging test is needed after the LED display screen is produced, and at present, the aging test is to connect the product test equipment through a wire, and the test method connected through the wire can meet certain use requirements, but has the defects of large material cost and inconvenience in operation, high line fault rate and low test efficiency, and the wire connection operation efficiency is low, the labor intensity is high, the labor cost is high, the wire material consumes large materials and is high in cost.

The to-be-solved technical problem of the utility model is to provide a need not the wire and connect, easy operation is convenient, intensity of labour is little, need not to consume that the wire rod is with low costs, the fault rate is low, the efficient LED display screen aging testing tool of measuring accuracy.

SUMMERY OF THE UTILITY MODEL

Need wire connection operating efficiency low, the big cost of labor of intensity of labour is high, the wire rod consumes big material cost height, troublesome poeration inconvenience for solving above-mentioned prior art, the many fault rates of circuit are high, efficiency of software testing low scheduling problem, the utility model discloses a following technical scheme:

the utility model provides an LED display screen aging test fixture, which comprises a fixture body, an LED display screen and a probe test mechanism, the jig body sequentially comprises a rear holeless copper plate, an insulating bakelite plate, a middle galvanized plate and a front holed copper plate from bottom to top, every two adjacent parts are bonded into a whole through universal glue, the LED display screen is arranged on the front hole copper plate of the jig body, the probe testing mechanism comprises a mounting seat, 4 electrified pin headers, a conductive copper block, a magnet and an electrified spring probe, the 4-way electrification pin header is fixed at the rear end of the mounting seat in a buckling manner, the electrification spring probe is arranged at the front end of the mounting seat through an insulation bakelite, the conductive copper block and the magnet are respectively arranged at the side edge of the front part of the mounting seat, the 4 electrified pin header is electrically communicated with the electrified spring probe through a pin header electrified lead, and an electrified spring probe of the probe testing mechanism penetrates through the LED display screen, is inserted into the through hole of the front hole copper plate and is fixed with the jig body through the magnet.

The beneficial effects of the utility model reside in that: the test probe directly fixes the product in the copper through hole and carries out the circular telegram ageing tests, need not the wire and connects, and easy operation is convenient, and intensity of labour is little, need not to consume the wire rod with low costs, and the fault rate is low, and the measuring accuracy is high efficiency.
