Description

A kind of cell phone multifunction test fixture

Technical field

The utility model relates to a kind of mobile phone test equipment, more particularly, to a kind of multi-functional mobile phone test fixture.

Background technique

Existing tool for testing mobile phone PCB adapter board bottom is thoroughly shut, and function is simple, can only test switching on and shutting down；It is powered After be unable to test internal current, can not find internal abnormality；And cell phone mainboard marginal test point is unable to measure, trivial operations are not square Just, it is unable to satisfy the demand of market in repair service.

Utility model content

The purpose of the invention of the present invention is to provide a kind of multi-functional mobile phone test fixtures.

It is as follows that the utility model solves the technical solution that above-mentioned technical problem is taken:

A kind of cell phone multifunction test fixture, including upper cover (1), pedestal (2), needle mould, PCB adapter board (4) and protection board (5), it is sequentially overlapped installation from top to bottom, wherein the needle mould is made of upper needle mould (3.1) and lower needle mould (3.2), the needle mould It is equipped with POGO PIN probe (3.3), the POGO PIN probe (3.3) runs through needle mould, can only be up and down, syringe needle both ends quilt Compression.Wherein upper cover (1), it is therefore an objective to compress cell phone mainboard, guarantee the conducting between POGO PIN probe (3.3) and cell phone mainboard Cell phone mainboard and PCB adapter board (4) are passed through POGO PIN probe (3.3) secondary conducting, Lai Shixian two panels cell phone mainboard by connection Separated test.

Preferably, the upper cover (1) includes hand button (1.1), the hand buckle shaft heart (1.2), hand button spring (1.3) and upper cover master Body (1.4), upper cap body (1.4) both sides are equipped with hand button (1.1), and hand button (1.1) is fixed on by the hand buckle shaft heart (1.2) rotation On upper cap body (1.4), hand button spring (1.3) are equipped between hand button (1.1) and upper cap body (1.4), it is solid by hand buckle assembly Determine upper cover position.

Preferably, the needle mould material is PPS, antistatic performance and good insulation preformance.

Preferably, POGO PIN probe (3.3) surface gold-plating, surface gold-plating conduction is more preferable and impedance value more It is low.

Preferably, the needle mould is fixedly connected by screw with pedestal (1), the pedestal (2), protection board (5) and PCB Pinboard (4), is fixed by screws.

A kind of cell phone multifunction test fixture described in the utility model, structure use metal material, the unsuitable modification of intensity height, Needle mould part is used into product PPS material, antistatic performance and good insulation preformance, and conducting medium is used into product POGO PIN probe, Surface gold-plating conduction is more preferable and impedance value is lower, and upper hand simple to operate, testing efficiency and accuracy greatly improve, mobile phone Draw more convenient measurement outside all test points of mainboard, most important solve maintenance personal and need to measure internal component current resistor value The problem of, the maintenance time of cell phone mainboard is greatly saved in more accurate judgement mainboard quality.The cell phone mainboard of same type is more After the new replacement, as long as replacement needle mould part can continue to use.

Other features and advantages of the utility model will illustrate in the following description, also, partly from specification In become apparent, or understood and implementing the utility model.The purpose of this utility model and other advantages can pass through Structure specifically indicated in the written description, claims, and drawings is achieved and obtained.

Detailed description of the invention

The utility model is described in detail with reference to the accompanying drawing, so that the above-mentioned advantage of the utility model is more It is clear.
