Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal testing technology, specifically a novel terminal testing mechanism. Background Technology
[0002] Currently, major terminal manufacturers in the market include IPX, Xuande, and Kexincheng. Terminal structures have evolved to five generations, each further subdivided based on wire harness size (e.g., 4th generation 0.81mm; 4th generation 1.13mm, etc.). Coaxial cable manufacturers include Shenyu, Chengjia, and Zhongzheng, offering a wide variety of wire harness sizes (e.g., 0.64mm, 0.81mm, 1.13mm, etc.). For coaxial cable harnesses with riveted terminal clips, factories still require electrical signal testing of the terminals. This process is currently mostly done manually using a multimeter. This method is difficult for extremely fine coaxial cable harnesses (most of which have a diameter ≤1mm). In actual production, this method is impractical for testing every single wire harness; random sampling is generally used. This leads to the influx of defective products, resulting in low work efficiency and, due to prolonged manual labor, irreversible and serious damage to the operator's eyesight.
[0003] Therefore, the novel terminal testing mechanism proposed in this patent is used to solve the aforementioned technical problems. Utility Model Content

[0006] The locking and positioning device includes a parallel finger cylinder support, and a parallel finger cylinder is installed on the parallel finger cylinder support. The output end of the parallel finger cylinder is respectively connected to a positioning lock block and a positioning irregular lock block, and a wire harness is clamped between the positioning lock block and the positioning irregular lock block.

[0026] The testing device 4 includes a lead screw module 41 mounted on a base plate 1, and the output end of the lead screw module 41 is connected to a locking and positioning device 3. An upper and lower cylinder 48 is mounted on the lead screw module 41, and the output end of the upper and lower cylinder 48 is connected to a T-shaped special plate 42. A test probe 47 is mounted on the T-shaped special plate 42, and the test probe 47 is compatible with the wiring harness 5.
[0027] A special mechanical structure is adopted, which uses parallel finger cylinders to drive positioning lock blocks and positioning irregular lock blocks. The coaxial cable bundle terminals are positioned and clamped by a cylinder and linear guide rail to assist in the propulsion. The detection method is to test the transmission of electrical signals by the copper core of the test probe in contact with the terminal. This automates the operation, reduces the difficulty of operation, reduces production time, and improves the accuracy of defect rate.
[0028] In this invention, the parallel finger cylinder support 31 is connected to the output end of the lead screw module 41 via an L-shaped bracket.

The upper and lower cylinders push the T-shaped special plate to the adjustable limit block one and the adjustable limit block two to cooperate with the locking and positioning device to complete the positioning. At this time, the test probe is in full contact with the terminal copper core and starts electrical signal detection.
