Problems solved by technology
[0002] The four sides of the stamp hole PCB board are metallized half-holes. In addition to the edges of the four sides, there are also exposed metallized half-holes connected to the edge on the inside. It is relatively difficult to test the function. The test racks provided on the market are all in contact with the metallized half-hole on the inner side by means of thimbles, so as to realize the test, or a multi-stamp hole PCB board test device disclosed in the invention patent 2011103951325. The trapezoidal top is large and the bottom is small. The upper end is fixed and the lower end has movable slots, and the height between the substrates can be adjusted by screws to ensure the pick-and-place and contact of the PCB board. Although it can be compatible with different sizes, the test rack takes up a lot of space. , because its trapezoidal structure is fixed, it is not very convenient to use, and it is not so easy to pick and place

Embodiment Construction
[0019] In order to make the technical means realized by the present invention clear, the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as Figure 1-4 As shown, a detection tool for a stamp hole PCB board includes an inner box 2, and a supporting plate 3 on the inner box 2, and a raised PCB fixing bracket 311 and four side thimble brackets 312 are arranged on the supporting plate 3 , the PCB board fixing bracket 311 is inside the four side thimble brackets 312, and the supporting plate 3 is also provided with a sliding groove 310 for the side thimble bracket 312 to slide and match, and the sliding groove 310 is arranged on the central vertical bisector , in the non-test state, the side thimble support 312 is at the outermost side of the sliding groove, close to the edge of the pallet. In the test state, the four side thimble brackets 312 are adjusted to press the stamp hole PCB 1 tightly through the sliding slots...

The invention discloses a stamp hole PCB board detection tool. The stamp hole PCB board detection tool comprises an inner box. A holding plate is arranged inside the inner box. Projected PCB board fixing supports and four side thimble supports are arranged on the holding plate. The PCB board fixing supports are arranged on the inner sides of the four side thimble supports. Sliding grooves for sliding matching of the side thimble supports are arranged on the holding plate. The sliding grooves are arranged on a center perpendicular bisectrix. A thimble is contained on the side thimble support. The thimble is an elastic thimble. The stamp hole PCB board detection tool utilizes a characteristic that the four sides of the stamp hole also expose the metalized half holes and utilizes horizontal elastic thimbles to contact with the metalized half holes to transmit signals and can be compatible with the stamp hole PCB board with different sizes.
