[0002] When the existing ICT (Automatic In-Circuit Test) machine is performing tests, it is necessary to plug in the test fixture to the 64-Pin cable on the machine. When disassembling / assembling the test fixture, it is necessary to plug and unplug 15 - 30 64-Pin cables. And because the 64-Pin cables are often plugged and unplugged, it is easy to damage the Pin interfaces. Moreover, the 64-Pin port of the test fixture needs to be connected to the machine interface using a 64-Pin cable and the order must be in one-to-one correspondence, so it is also easy to insert the cables in the wrong order during installation.

[0006] The lower end surface of the machine panel pin has multiple machine conductive contacts, and each machine conductive contact is electrically connected to the corresponding Pin port on the upper end surface of the machine panel pin;

[0007] A fixture panel pin is fixed on the top of the fixture body, and the upper end surface of the fixture panel pin has multiple fixture conductive contacts;

[0008] When the fixture body is installed on the machine body, each fixture conductive contact on the fixture panel pin is in contact with the corresponding machine conductive contact on the machine panel pin.

[0009] Furthermore, pneumatic pressing devices for pressing the fixture panel pin and the machine panel pin are respectively arranged on both sides of the machine body.

[0016] like Figure 1-2 As shown, the connection structure between the ICT machine and the fixture of the utility model includes a machine body 1 and a fixture body 2. The machine body 1 has a plurality of switch circuit boards 3 inside, and each switch circuit board 3 is electrically connected to a 64-pin flat cable 5 on the machine body 1. An organic panel pin 4 is fixed on the bottom of the machine body 1, and the upper end surface of the machine panel pin 4 is electrically connected to the pin pin corresponding to the 64-pin flat cable 5 through a pin port;

[0017] The lower end surface of the machine panel pin 4 has a plurality of machine conductive contacts 41, and each machine conductive contact 41 is electrically connected to a corresponding pin port on the upper end surface of the machine panel pin 4;

[0018] A jig panel needle 6 is fixed on the top of the jig body 2, and the upper end surface of the jig panel needle 6 has a plurality of jig conductive contacts 61;

[0019] When the jig body 2 is installed on the machine body 1, each jig conductive contact 61 on the jig panel pin 6 contacts with the corresponding machine conductive contact 41 on the machine panel pin 4. In order to improve the contact reliability, the machine conductive contact 41 and the corresponding jig conductive contact 61 adopt a parent-child plug-in structure for contact and matching.

The push plate 8 cooperates with the convex part 21 on the side of the jig body 2 to drive the jig body 2 to rise synchronously, so that the jig panel pins 6 and the machine panel pins 4 are pressed together.

[0021] The utility model uses two panel pins to switch the test fixture, eliminating the need for cumbersome plugging and unplugging of the 64-Pin cable 5, achieving rapid switching of the test fixture, improving the efficiency of replacing the test fixture, avoiding incorrect insertion of the 64-Pin cable, and reducing damage caused by repeated plugging and unplugging of the 64-Pin cable.
