Description

Technical Field

[0001] The utility model relates to the technical field of line testing, and more particularly to a bare wire signal integrity testing fixture. Background Art

[0002] Bare wire signal integrity testing is a critical step in verifying the performance of a cable or cable connection. The purpose of this test is to ensure that both ends of the cable are properly connected and that signals can be transmitted between them. This is essential for maintaining the normal operation of network connections, audio and video equipment, and other electronic devices.

[0003] Deficiencies of existing technology: Under existing technology, when conducting a bare wire signal integrity test, it is necessary to insert the bare wire into the contact of the fixture, and then press and position the bare wire and the contact to maintain good contact. However, the current pressing and positioning method is relatively cumbersome to operate, and often requires the use of tools to tighten bolts, etc., which brings inconvenience to the staff. Some existing methods also use cylinder pressing and positioning methods. Although the operation is simple, the cost is relatively high.

[0004] In addition, existing fixtures are placed on a workbench when in use. To ensure stability, holes are generally drilled on the workbench table top, and then the fixture is fixed to the workbench table top with screws. However, this method may damage the workbench and is inconvenient to adjust the position of the fixture. Utility Model Content

A moving block 33 is provided at the bottom of the gear 32. A rack 34 is fixedly mounted on the surface of the moving block 33, and the rack 34 is meshed with the gear 32.

[0025] The positioning assembly 4 includes a positioning plate 41 and a sliding rod 42 . The top of the sliding rod 42 is fixedly connected to the bottom of the fixture body 1 . There are two sliding rods 42 , and the positioning plate 41 is sleeved on the surface of the sliding rod 42 .

[0026] Furthermore, a rotating block 21 is fixedly connected to the pressing block 2, and two rotating blocks 21 are symmetrically arranged. A fixed block 22 is fixedly connected to the top of the fixture body 1, and two fixed blocks 22 are symmetrically arranged. A rotating rod 23 is rotatably connected between the two fixed blocks 22. The rotating block 21 is fixedly installed on the surface of the rotating rod 23, and one end of the rotating rod 23 extends to the inside of the mounting shell 31. When the rotating rod 23 rotates around its own axis, the pressing block 2 and the rotating block 21 as a whole can rotate synchronously around the axis of the rotating rod 23.

[0027] Furthermore, the gear 32 is fixedly mounted on the surface of the rotating rod 23, one end of the coil spring 38 is fixedly connected to the surface of the rotating rod 23, and the other end of the coil spring 38 is fixedly connected to the inner wall of the mounting shell 31. The bottom of the inner cavity of the mounting shell 31 is fixedly connected to a fixing frame 35, and one side of the fixing frame 35 is fixedly connected to the guide rod 351. The moving block 33 is sleeved on the surface of the guide rod 351, and the moving block 33 and the guide rod 351 form a sliding guide cooperation along the axis direction of the guide rod 351. One side of the moving block 33 is fixedly connected to a connecting rod 36, and one end of the connecting rod 36 passes through the inner wall of the mounting shell 31 and extends outward. One end of the connecting rod 36 is fixedly connected to a buckle 37. The elastic force of the coil spring 38 can drive the pressure block 2 to rotate downward around the axis of the rotating rod 23. The staff can tighten the coil spring 38 by pulling the buckle 37 by hand, and the pressure block 2 rotates upward around the axis of the rotating rod 23.

[0028] Furthermore, the bottom ends of the two sliding rods 42 are fixedly connected by a strip plate 43, a threaded sleeve 45 is fixedly installed at the center of the strip plate 43, a threaded rod 44 is threadedly connected inside the threaded sleeve 45, the top end of the threaded rod 44 is rotatably connected to the bottom of the fixture body 1, and a rotating handle 46 is fixedly connected to the bottom end of the threaded rod 44.

[0029] The staff can insert the workbench table top between the jig body 1 and the positioning plate 41, and manually twist the rotating handle 46 to rotate the threaded rod 44 around its own axis. While the threaded rod 44 rotates, it moves synchronously upward along its own axis. The threaded rod 44 moves and drives the positioning plate 41 to move synchronously upward along the sliding rod 42. The jig body 1 and the positioning plate 41 jointly clamp the workbench table top, and the position of the jig body 1 is fixed.

[0030] The working principle of the present invention is as follows: during actual operation, the staff pulls the buckle 37 by hand, the buckle 37 moves and drives the moving block 33 to move synchronously along the guide rod 351 toward the fixed frame 35 through the connecting rod 36, the moving block 33 moves and drives the rack 34 to move synchronously, the rack 34 moves and drives the rotating rod 23 to rotate synchronously around its own axis through the gear 32. During the rotation of the rotating rod 23, the winding spring 38 is gradually tightened and the elastic force increases, the rotating rod 23 rotates and drives the pressure block 2 to rotate upward synchronously around the axis of the rotating rod 23 through the rotating block 21. The staff inserts the bare wire along the lead groove 11 and makes one end of the bare wire enter the top of the contact 12. The staff then loosens the buckle 37. The elastic force of the winding spring 38 drives the rotating rod 23 to rotate in the opposite direction around its own axis. The rotating rod 23 rotates and drives the pressure block 2 to rotate downward synchronously around the axis of the rotating rod 23. The buckle 37 also returns to the initial position synchronously. The pressure block 2 presses one end of the bare wire tightly so that one end of the bare wire maintains good contact with the contact 12.
