[0014] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1-4 As shown, the embodiment of the utility model includes:

[0016] A double-sided quick-connect EOLT fixture comprises a sub-fixture 1, an x-axis rail 2, an active slide 3, a driven slide 4, a z-axis bearing 5, a rotating swing arm 6, a joint bearing rod 7, an electrical connector 8, and a tested product profiling seat 9. The sub-fixture 1 is provided with a pair of x-axis rails 2, an active slide 3 and a driven slide 4 are mounted on the x-axis rails 2, a z-axis bearing 5 is provided between the x-axis rails 2, the z-axis bearing 5 is connected to a rotating swing arm 6, and a joint bearing rod 7 is connected to each of the two ends of the rotating swing arm 6, the joint bearing rod 7 is respectively connected to the active slide 3 and the driven slide 4 for traction, the active slide 3 and the driven slide 4 are both provided with electrical connectors 8, a tested product profiling seat 9 is centrally provided between the active slide 3 and the driven slide 4, and each electrical connector 8 is matched on two opposite sides of the tested product profiling seat 9.

[0017] Among them, the sub-clamp 1 is carried on a mother clamp 10, and the mother clamp 10 is provided with a plurality of positioning blocks 11 matching the sub-clamp 1. The mother clamp 10 is provided with an upward primary interface 12, and the sub-clamp 1 is provided with a downward secondary interface 13. The primary interface 12 is matched and docked with the secondary interface 13.

[0018] Furthermore, the z-axis bearing 5 is connected in the middle of the rotating swing arm 6 .

[0019] Furthermore, the active slide 3 is externally connected to a pull rod 14 parallel to the x-axis rail 2 , and the pull rod 14 is connected to a push-pull quick clamp 15 parallel to the x-axis rail 2 .

[0020] like Figure 1 As shown, the sub-clamp 1 and the mother clamp 10 are combined together using a split quick-release structure. During the EOLT test, since the mother clamp 10 uses a unified primary interface 12, the mother clamp 10 can be compatible with various types of sub-clamps 1 to achieve rapid changeover.

[0021] like Figure 2 As shown, the push-pull quick clamp 15 drives the pull rod 14 to move along the x-axis through manual operation, and the pull rod 14 drives the active slide 3 to slide. Since the active slide 3 and the driven slide 4 are simultaneously connected to the rotating swing arm 6, the sliding of the active slide 3 can simultaneously drive the driven slide 4 to move.

[0022] like Figure 3 As shown, the length of the joint bearing rod 7 is greater than the distance between the active slide 3 / driven slide 4 and the z-axis bearing 5. The z-axis bearing 5 is set at the midpoint of the rotating swing arm 6, so that the active slide 3 and the driven slide 4 can move in opposite directions to achieve synchronous approach and separation.

[0023] like Figure 2As shown, during the process of the active slide 3 and the driven slide 4 being brought together synchronously, the product under test placed on the product profiling seat 9 can establish electrical connections with each electrical connector 8 . The electrical connectors 8 are integrated in the secondary interface 13 .

[0024] like Figure 4 As shown, a test instrument is integrated at the rear of the female fixture 10 , and the test instrument can quickly establish an electrical connection with the product under test through the docking of the primary interface 12 and the secondary interface 13 .

[0025] like Figure 2 As shown, the driven slide 4 is also provided with a sub-bracket 17, and the sub-bracket 17 is provided with a proximity switch 16, and the proximity switch 16 is directly opposite to the tested product profiling seat 9, and the proximity switch 16 is externally connected to an indicator light or an audible and visual alarm. In this way, when the quick clamp 15 is manually pushed and pulled, it can be judged whether the electrical connector 8 is correctly connected according to the prompt signal of the proximity switch 16.

[0026] In summary, the utility model provides a double-sided quick-connect EOLT clamp, which realizes the purpose of synchronous electrical connection between the front and rear ends by rotating the swing arm 6 and the synchronous linkage of the two slides. At the same time, the sub-clamp 1 and the mother clamp 10 are combined to achieve the purpose of quick disassembly and change of type, which can significantly improve the circuit connection efficiency and reliability of the EOLT process, and effectively reduce labor intensity.
