[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] likeFigures 1-4 As shown, the embodiments of this utility model include:

[0018] A quick-change EOLT male-female clamp includes a female clamp 1 and a female clamp 2. The female clamp 1 is provided with a rear connector 3 and a plurality of guide blocks 4 that guide to the rear connector 3. The female clamp 2 is placed between the guide blocks 4. The female clamp 2 is provided with a front connector 5 that matches and mates with the rear connector 3. The female clamp 2 has a wire hole 6 on the back side of the front connector 5. The female clamp 1 is provided with a Z-axis rotating shaft 7. The Z-axis rotating shaft 7 is provided with a lever 8. One end of the lever 8 is provided with a pulley 9, which matches the wire hole 6.

[0019] The rotation radius of the pulley 9 on the lever 8 is adapted to the depth distance between the front connector 5 and the rear connector 3.

[0020] Furthermore, the guide block 4 is elongated and surrounds the outer edge of the sub-clamp 2, or is inverted L-shaped and surrounds the upper edge of the sub-clamp 2.

[0021] Furthermore, the sub-clamp 2 is provided with a product-testing contour base 10, and a rotary cylinder 11 is provided next to the product-testing contour base 10. The rotary cylinder 11 is equipped with a pressure block 12 that matches the top of the product-testing contour base 10.

[0022] Furthermore, the sub-clamp 2 is provided with a test product docking port 13, and a flat shelf 14 is suspended below the test product docking port 13. A Z-axis slide cylinder 15 is provided on the flat shelf 14, and a terminal connector 16 matching the test product docking port 13 is provided on the Z-axis slide cylinder 15. The terminal connector 16 is sequentially connected to the front connector 5 and the rear connector 3.

[0023] Furthermore, the female clamp 1 is provided with a clearance opening 17 for adapting to the flat shelf 14, and the rear connector 3, front connector 5, and terminal connector 16 are all arranged on the lower side of the clearance opening 17. The female clamp 1 is provided with a shell 18 that covers the rear connector 3, front connector 5, and terminal connector 16.

[0024] The empty sub-clamp 2 is stored flat in the storage location via the flat shelf 14. Before testing, the product to be tested is placed on the product profile holder 10, and the entire sub-clamp 2 is manually moved onto the mother clamp 1. During placement, the flat shelf 14 is first inserted into the clearance opening 17, and then the entire sub-clamp 2 is placed on the edge of the clearance opening 17. The guide block 4 is used to adjust it to the appropriate position until the wire control can be fitted onto the pulley 9. Then, the lever 8 is turned, causing the pulley 9 to rotate 45 degrees around the z-axis 7. During the rotation, the front connector 5 on the sub-clamp 2 is pushed by the pulley 9 to connect to the rear connector 3, thus completing the changeover. Figure 4 As shown, the air pipe connected to the cylinder and the wiring harness connected to the terminal connector 16 converge on the front connector 5. The front connector 5, pushed by the pulley 9, can instantly connect to the rear connector 3, immediately completing the connection of the circuit and air path.

[0025] In summary, this utility model provides a quick-change EOLT male-female clamp 1, which addresses the problem of needing to rewire after the tested product is changed. It uses a lever 8 to drive the female clamp 2 to facilitate connector connection, thereby improving changeover efficiency and reducing the difficulty of test assembly.
