Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as Figure 1-2 As shown, an ICT test fixture, an ICT test fixture, includes a test box 9, a connecting plate 10, a carrier plate 1, a needle plate 14, a pressure plate 2, a hinge seat 3, a rotating shaft 4, a pull rod 7, and a rotating handle 13. The upper hook angle 5 and the lower hook angle 6, the test box 9 is connected to the carrier plate 1 through the connecting plate 10, an accommodation cavity is formed between the test box 9 and the carrier plate 1, and a placement plate is connected to the bottom of the carrier plate 1 11. There are several cams 12 that can rotate simultaneously on the placement plate 11. One of the cams 12 is connected to the rotating handle 13. A needle plate 14 is arranged on the top of the cam 12. The length of the needle plate 14 is shorter than that of the carrier plate 1. length. The probes on the needle board 14 can ext...

The invention discloses an ICT testing fixture which comprises a testing box, a connecting plate and a carrier plate. The testing box is connected with the carrier plate through the connecting plate, and a containing cavity is formed between the testing box and the carrier plate. The ICT testing fixture is characterized in that a placing plate is connected to the bottom of the carrier plate, a plurality of cams are arranged on the placing plate, one of the cams is connected with a rotating handle, a probe plate is arranged on the tops of the cams, probes on the probe plate extend out of the carrier plate to make contact with a PCB, two hinge mounts are arranged at the back end of the top of the carrier plate, the back end of a pressing plate is movably connected between the two hinge mounts, a pull rod is connected between the tops of two rotating shafts, and a lower hook corner is arranged at the bottom of each rotating shaft. According to the ICT testing fixture, the problems that testing results are affected because the PCB is not pressed tightly by an ICT testing fixture, and the equipment is large in occupied space, high in manufacturing cost and low in testing efficiency are solved; the ICT testing fixture is capable of keeping the PCB stable, low in manufacturing cost and easy and convenient to operate, and the PCB can be placed and taken conveniently.
Description
technical field [0001] The invention relates to a PCB board test fixture, in particular to an ICT test fixture. Background technique [0002] The current ICT test fixture is an online detection fixture, which is a standard test equipment for testing the electrical properties and electrical connections of online components to check manufacturing defects and defective components. It is mainly used to check the open and short circuit conditions of individual components on-line and each circuit network. However, the carrier board of the current testing organization only plays a role in placing the PCB board, and does not compress the PCB board, so that the PCB board may move during the test, which will affect the test result. At the same time, it is very troublesome to take and place the PCB board of the current test fixture, and the test efficiency is low, which cannot meet the needs of the test. In addition, the current test fixtures mostly use motors or cylinders to drive t...
