The clamping block 9 is made of rubber or plastic with a textured surface and can clamp circuit board pins of different diameters. A slot plate 5 is fixedly connected inside the connector 6. The slot plate 5 provides an insertion and fixing position for the plug 4 of the test end connector 3. A socket 7 is fixedly connected inside the slot plate 5 to realize the connection and separation of the test end connector 3 and the connector 6. The protection components include a connector protective sleeve 2. The inner wall of the connector protective sleeve 2 is fixedly connected to the outer wall of the connecting wire 1. One end of the spring 8 is fixedly connected to one side of the outer wall of the slide bar 10, and the other end of the spring 8 is fixedly connected to the inside of the connector 6. The outer wall of the plug 4 is slidably connected to the inside of the socket 7 to realize the detachable connection between the test end connector 3 and the connector 6.

[0024] Reference Figure 1 and Figure 3 One end of the connecting wire 1 is fixedly connected to a feedback connector 12, which is used to transmit the feedback signal from the circuit board to the test equipment. A slot plate 13 is fixedly connected to the outer wall of the feedback connector 12. The slot plate 13 has a slot for engaging with a steel ball 15. The outer wall of the slot plate 13 is slidably connected to the inner wall of the connecting seat 14. The connecting seat 14 provides a base for the installation and connection of the feedback connector 12. The connecting seat 14 contains a steel ball 15, which engages with the slot of the slot plate 13 to lock and unlock the feedback connector 12. A plug is fixedly connected inside the connecting seat 14. 19. Plug 19 is used to connect to test equipment. A slide plate 18 is fixedly connected to the outer wall of connector 14.

[0025] Working principle: The test connector 3 is connected to the socket 7 of the slot plate 5 inside the connector 6 via the plug 4. The clamping component inside the connector 6 is used to connect the circuit board pins. Pulling the pull ring 11 causes the slide bar 10 to move outward against the elastic force of the spring 8, and the clamping block 9 opens. After placing the pin, the pull ring 11 is released, and the spring 8 returns to its original position, causing the clamping block 9 to clamp the pin. This can accommodate pins of different diameters and ensure stable electrical connection. When replacing the test connector 3, the plug 4 can be pulled out to remove the old connector and replace it with the new one. The feedback connector 12 is connected to the connector 14 via the slot plate 13. Under normal conditions, the steel ball 15 is fixed by being inserted into the slot of the slot plate 13 under the action of the spring 17 and the slider 16. When replacing, push the slider 16 to compress the spring 17 and separate it from the steel ball 15. The steel ball expands and dislodges from the slot, the slot plate 13 and connector are pulled out, and after inserting the new connector, the steel ball 15 is re-slotted into the slot under the action of spring 17 to complete the fixation, ensuring a stable connection with the test equipment. The connecting line 1 is responsible for transmitting the test signal. The connector protective sleeve 2 on its outer wall provides physical protection to prevent damage from external forces during signal transmission, insulation protection to avoid leakage, dustproof and moisture-proof to maintain stable performance, and ensures that the test signal is accurately transmitted between the components, ensuring accurate and reliable testing. During the test, the test equipment is started, and the test signal is transmitted to the test end connector 3 through the connecting line 1. After being processed by the circuit board, the feedback signal is transmitted back to the test equipment through the feedback end connector 12 and the connecting line 1. The test equipment analyzes and processes the signal to obtain the test result.
