Description

Technical Field

[0001] The utility model relates to the field of ICT electrical testing, in particular to a gold finger card insertion module supporting fast card replacement. Background Art

[0002] The ICT electrical tester's gold finger adapter card is a device used to test printed circuit board assemblies (PCBAs). It uses test probes to contact test points on the PCB layout to detect opens and shorts, as well as the soldering condition of all components. ICT testing can quickly and accurately locate faulty components or open and short circuit points, improving production efficiency and reducing costs.

[0003] During testing, conventional screw-mounted adapter cards required removing the mounting block on the adapter card before replacing it. After replacing the adapter card, the screws on the mounting block had to be tightened again. This complicated and time-consuming process reduced work efficiency and increased production costs. Therefore, it was crucial to develop a simple, fast-replacing device for mounting adapter cards. Utility Model Content

The design of the present invention aims to make the replacement of gold finger adapter cards more convenient and quick, thereby improving production efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: it includes an adapter card floating block and an adapter card pressure block, and a plurality of countersunk through holes are symmetrically arranged on the adapter card pressure block, and the countersunk through holes are equipped with contour screws with reset springs, and the contour screws pass through the countersunk through holes and are fixedly matched with the adapter card floating block. A limiting groove is provided on the upper surface of the adapter card floating block. When replacing the gold finger adapter card, the adapter card pressure block is lifted, and then the gold finger adapter card is inserted into the limiting groove, and the adapter card pressure block is released. Under the action of the reset spring, the adapter card floating block and the adapter card pressure block cooperate to clamp the gold finger adapter card.

[0006] Based on the above, the present invention adopts a latch-type design. When replacing the gold finger adapter card, the adapter card pressure block is manually lifted and then the gold finger adapter card is replaced. After the replacement is completed, the gold finger adapter card pressure block is released. Under the action of the reset spring, the adapter card pressure block automatically resets and presses the gold finger adapter card on the limit slot. The process does not require the removal of screws, the structure is simple, and the replacement of the gold finger adapter card is convenient and quick. While ensuring the stability of the card insertion test, it also improves production efficiency.

[0007] Furthermore, connection holes are provided on the left and right sides of the adapter card floating block, and side contour screws and side springs are provided on the connection holes. The side contour screws pass through the adapter card floating block and are fixedly connected to the external mechanism.

[0008] Based on the above, the side contour screws and the side springs cooperate to form an elastic structure. When the gold finger adapter card is inserted into the limit slot and collides with the edge of the limit slot, the side spring will generate a buffering elastic force, which protects the gold finger adapter card and avoids damage.

[0009] Furthermore, the limiting groove is provided with a positioning hole corresponding to the through hole on the gold finger adapter card, and the lower surface of the adapter card pressing block is provided with a positioning pin corresponding to the positioning hole.

[0010] Based on the above, the positioning pin cooperates with the positioning hole to fix and limit the gold finger adapter card, thereby improving the stability of the test.

[0011] Furthermore, the adapter card pressing block is provided with pull grooves on the front and rear sides.

[0012] Based on the above, the pull groove facilitates grabbing the adapter card pressing block.

[0013] Furthermore, the limiting groove includes a first limiting groove and a second limiting groove, the groove diameter of the first limiting groove is larger than the groove diameter of the second limiting groove, the first limiting groove and the second limiting groove form a positioning corner edge through the groove diameter difference, the edge of the gold finger adapter card is provided with a corner structure, the contour of the corner structure is adapted to the positioning corner edge, and the card insertion end of the limiting groove is also provided with a chamfer.

[0014] Based on the above, the edge of the gold finger adapter card is provided with a corner structure, and the outline of the corner structure is adapted to the positioning corner edge. During the card insertion process, the chamfer plays a guiding role, and the corner structure cooperates with the positioning corner edge for rapid positioning, thereby improving replacement efficiency.
