[0005] A kind of multi-module structure test fixture, including jig frame, detection plate is equipped on the jig frame, the jig also includes buckle, carrier plate module, needle plate module and bottom version;
[0006] The bottom version is arranged on the detection plate;
[0007] The bottom version is detachably mounted with several needle plate modules;
[0008] The needle plate module is in contact with the detection plate;
[0009] The bottom version is provided with buckle, and the carrier plate module is arranged on the bottom version by buckle.
[0010] Through the above structure, the needle plate module and carrier plate module are sequentially installed on the bottom version, and are connected with the detection plate when being installed on the jig frame, to form a jig, which facilitates automatic detection test operation. The needle plate module and carrier plate module can be installed separately, and if damaged, the module can be replaced directly. The overall structure is simple to disassemble and assemble, and the parts or probes of the replaced module are convenient to replace, with low replacement and maintenance cost. The modular and buckle design speeds up the assembly and replacement of parts, so that the jig is better matched with the automated machine for testing, and the testing progress is accelerated.
[0011] Excellent, the bottom version is provided with first guide pillar.
[0012] Therefore, the first guide pillar can ensure the accurate installation of the carrier plate module.
[0013] The needle plate module comprises an upper needle block, a lower needle block, a probe and a second guide pillar.
[0014] The probe is arranged between the upper needle block and the lower needle block, and the upper needle block and the lower needle block are positioned and installed through the second guide pillar.
[0015] The needle plate module can directly replace the needle block module on the fixture, and the operation is simple and convenient.
[0016] The carrier plate module comprises a cover plate, a cushion plate and a carrier plate bottom plate.
[0017] The carrier plate bottom plate is provided with the cushion plate.
[0018] The cover plate is hinged to the carrier plate bottom plate.
[0019] The cover plate is provided with a product placing hole at the position corresponding to the cushion plate.
[0020] Therefore, after the carrier plate module is installed, the product can be placed and fixed on the cushion plate through the product placing hole during the test, the product placed on the cushion plate is connected with the corresponding needle plate module, and the test can be performed.
