Detailed Description

The technical solution protected by the present invention is specifically described below with reference to the accompanying drawings.

A test apparatus for LED panels, consisting essentially of: the base plate 2 and the bearing plate 1 on the base plate 2 of bottom, connect through the elastic device 8 between base plate 2 and the bearing plate 1, make the bearing plate 1 can move up and down relative to the base plate 2, there are multiple blade needles 7 in the middle part of the said base plate 2, one end of the said blade needle 7 is fixed to the bottom plate 3 of the inferior part of the base plate 2, another end of the said blade needle 7 is outstanding from the base plate 2 and deeply enters the needle groove 12 of the bearing plate 1, and when the bearing plate 1 is in the initial condition, the height of the blade needle 7 is lower than the top of the needle groove 12. In this embodiment, elastic device 8 sets up to both ends for the threaded rod, and the middle part is the form of straight-bar the outside cover of straight-bar is equipped with the spring, puts into the spacing groove 11 back of accepting the board when being surveyed the product, and the board 1 is accepted in the push-down, because the spring shrink, accepts the board and moves down, and the needle groove is stretched out at 7 tops of blade needle to with being surveyed the contact of product terminal, detect.

In order to prevent the adjacent blade needles 7 from contacting and causing short circuit, a plurality of guide plates 6 are arranged at the blade needles in the base plate, a plurality of slotted holes are formed at the guide plates 6, so that the blade needles can penetrate through the slotted holes, a limiting plate 5 is arranged above the plurality of guide plates 6, a plurality of slotted holes are formed at the limiting plate 5, and the blade needles 7 can penetrate through the slotted holes.

The utility model discloses in, for the ease of processing, the quantity of deflector 6 sets up to the polylith, adopts polylith deflector superimposed mode. The purpose of this kind of design is, have the slotted hole in the deflector 6, if the thickness of deflector 6 is great, the slotted hole is difficult to process the shaping, so adopt the mode that a plurality of deflectors 6 stack, reduced the processing degree of difficulty of slotted hole.
