DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] Please refer to Figure 1 , Figure 2 and Figure 6 , the present application provides a technical solution: data center high-speed copper cable test fixture, including support table 1, the top of support table 1 is fixedly connected with test table 2, and the top of test table 2 is fixedly connected with support frame 3, test table 2 is provided with clamping mechanism 4 for clamping the cable to be tested, support frame 3 is provided with positioning mechanism 6 for positioning the cable, positioning mechanism 6 includes fixing seat 16;

[0029] The fixing seat 16 is fixedly connected in the support frame 3, and the fixing seat 16 is provided with a vertical lifting groove 17, and the lifting groove 17 is provided with a positioning block 19 for pressing and positioning the cable, the top of the support frame 3 on one side of the clamping mechanism 4 is fixedly connected with a U-shaped frame 13, and the U-shaped frame 13 is provided with an adjustable mounting seat 14, the bottom of the mounting seat 14 is provided with a camera 15 for monitoring the positioning position of the cable, and the top of the support frame 3 away from the clamping mechanism 4 is provided with a pressing control mechanism 5 for driving the positioning block 19 to descend.

[0030] It should be noted that the focal length of the camera 15 is 11-16mm, so that the camera 15 and the U-shaped frame 13 thereon can be made very compact, which can be easily integrated in the limited space of the U-shaped frame 13, mounting seat 14, etc. of the fixture, and will not affect the overall structural design of the fixture, the movement of other mechanisms or cause the fixture to become heavy because the volume of the camera 15 is too large;

[0031] In the test fixture, the camera 15 needs to be close to the cable and positioning mechanism 6 for shooting, the working distance is short, and the focal length of 11-16mm is very suitable for close-up shooting. In the limited installation space, it can still be in focus and clear, accurately capture the positioning state of the cable and the position of the pressing block, and ensure the effectiveness of monitoring.

[0032] Please refer to Figure 6 The top of the fixed seat 16 is symmetrically provided with a mounting groove, and the second spring 23 is fixedly connected in the mounting groove. The top of the two second springs 23 is fixedly connected with a supporting plate 21, and the bottom of the supporting plate 21 is fixedly connected with a lifting seat 18. The lifting seat 18 is in a frame type structure as a whole. The first spring 22 is fixedly connected to the bottom of the supporting plate 21 in the lifting seat 18, and the end of the first spring 22 is fixedly connected with the positioning block 19. The outer side of the positioning block 19 is fixedly connected with a connecting seat 20, and the connecting seat 20 is slidingly connected in the lifting groove 17.

[0033] It should be noted that when the upper pressing block 31 is pressed down, the force is first directly applied to the supporting plate 21. The supporting plate 21 transmits the pressure through the lifting seat 18 at the bottom, and starts to compress the second spring 23. With the continuous pressure, the first spring 22 connected directly with the positioning block 19 starts to be compressed. The first spring 22 more directly feels the reaction force from the wire harness. If the wire harness diameter is slightly larger or locally uneven, the first spring 22 can absorb this part of the difference through its own deformation, ensuring that the positioning block 19 remains in contact with the surface of the wire harness. During the entire process, the connecting seat 20 slides in the lifting groove 17 of the fixed seat 16, providing accurate vertical guidance for the up-and-down movement of the positioning block 19, effectively preventing the positioning block 19 from tilting, jamming or rotating during the pressing process, and ensuring the smoothness and accuracy of the pressing action.

[0034] Please refer to Figure 3 and Figure 7 The lower pressing control mechanism 5 includes a fixed frame 24, and the top end of the supporting frame 3 away from the U-shaped frame 13 is fixedly connected with the fixed frame 24 through a screw. The top end of the fixed frame 24 is hingedly connected with a control rod 26, and the control rod 26 is hingedly connected with an arc-shaped connecting rod 25. The bottom end of the arc-shaped connecting rod 25 is hingedly connected with a lifting rod 28. The top of the fixed frame 24 is provided with a vertical sliding hole, and the lifting rod 28 is slidingly connected in the sliding hole.

[0035] It needs to be explained that, in use, the operator presses down the free end of the operating lever 26, because the operating lever 26 is connected with the arc-shaped connecting rod 25 through the hinge point, the middle part of the operating lever 26 is hinged with the upper end of the arc-shaped connecting rod 25, when the operating lever 26 rotates downward, it will pull the upper end of the arc-shaped connecting rod 25 backward, the lower end of the arc-shaped connecting rod 25 is hinged with the lifting rod 28, when the upper end is pulled backward, the arc-shaped connecting rod 25 will push or pull the lifting rod 28, so that it moves strictly up and down in the vertical sliding hole of the fixed frame 24, thereby ensuring that the lifting rod 28 cannot sway forward and backward or left and right, but only moves along the preset vertical path.

[0036] Please refer to Figure 7 The lifting rod 28 is provided with a threaded rod 29 which is arranged to be lifted, and the end of the threaded rod 29 penetrates through the lifting rod 28, the outer side of the end of the threaded rod 29 located outside the lifting rod 28 is threadedly connected with an adjusting nut 30, and the bottom of the threaded rod 29 is fixedly connected with a pressing block 31 which is located directly above the supporting plate 21.

[0037] It needs to be explained that, in use, the to-be-tested wire harness is directly arranged between the two clamping seats 8, the arc-shaped grooves 9 are rotated to adjust the rotating knob 12 to rotate the adjusting rod 11, the adjusting rod 11 is threadedly connected with the test table 2, so that the clamping seat 8 is pushed to slide in the groove 7, and the length scale on the two adjusting rods 11 is adjusted to clamp the wire harness by the two clamping seats 8.

[0038] Then the adjusting handle 27 is swung downward to pull the operating lever 26 to rotate, under the action of the arc-shaped connecting rod 25, the lifting rod 28 is lowered to push the pressing block 31 to press the supporting plate 21, when the supporting plate 21 is pressed, the lifting seat 18 is lowered to push the lifting groove 17 to slide downward, so that the positioning block 19 is pressed tightly on the top of the wire harness, and the wire harness is clamped stably.

[0039] When the pressure is transmitted through the supporting plate, first, the second spring 23 is compressed, then the pressure is finally applied to the positioning block 19 through the first spring 22, under the guidance of the connecting seat 20 and the lifting groove 17, the positioning block 19 moves stably downward until it is pressed tightly on the upper surface of the wire harness, and the first spring 22 and the second spring 23 form a double buffering system to prevent the damage of the insulation layer or the internal wire of the wire harness due to excessive downward pressure.

[0040] When the downward pressure is not enough, the adjusting nut 30 is rotated first when the operating lever 26 is not controlled, the threaded rod 29 is lowered through the threaded connection between the threaded rod 29 and the adjusting nut 30, so that the pressing block 31 is lowered, after the adjustment is completed, the operating lever 26 is controlled again, the downward pressing strength of the positioning block 19 can be further improved, and the wire harness can be better positioned.

[0041] During the whole pressing positioning process, the camera 15 installed in the mounting seat 14 of the U-shaped frame 13 continuously monitors the pressing area of the wire harness, the U-shaped frame 13 can be rotationally adjusted so that the camera 15 can be aligned with the optimal observation angle, and the operator can observe the picture taken by the camera 15 in real time through the external display device, and intuitively confirm whether the positioning block 19 has accurately pressed the wire harness to the preset test position, thereby effectively avoiding the test inaccuracy problem caused by visual blind area or misjudgment.

[0042] After the test is completed, the operator lifts the control rod 26 upward, and under the action of the lever principle, the lifting rod 28 and the pressing block 31 rise to release the pressure on the supporting plate 21.

[0043] Please refer to Figure 2 and Figure 4 , the positioning mechanism 6 includes clamping seats 8, one end of the test table 2 is provided with a lifting groove 17, and the clamping seats 8 are symmetrically arranged in the lifting groove 17. An arc-shaped groove 9 matched with the cable to be tested is formed in the top end of the side wall of the clamping seat 8. Threaded holes are formed in the two sides of the test table 2 at one end of the groove 7, and the adjusting rods 11 are threadedly connected in the threaded holes. One end of the adjusting rod 11 inside the groove 7 is rotationally connected with the clamping seat 8 through a bearing.

[0044] It should be noted that when clamping the wire harness, the operator rotates the adjusting rods 11 located on both sides of the test table 2. When the adjusting rods 11 are rotated, the adjusting rods 11 push the clamping seats 8 to move under the action of the threads. Under the pushing of the two adjusting rods 11, the two clamping seats 8 move synchronously and oppositely along the guide device, and finally the arc-shaped grooves 9 on the top thereof tightly embrace and fix the wire harness from both sides.

[0045] Please refer to Figure 4 , the guiding rods 10 are symmetrically fixed between the two inner walls of the groove 7, and the guiding holes in the horizontal direction are symmetrically formed in the clamping seats 8. The guiding rods 10 are slidingly connected in the guiding holes of the clamping seats 8.

[0046] It should be noted that the two guiding rods 10 are fixed between the two inner walls of the groove 7, forming a solid and parallel guide rail. The guiding holes in the clamping seats 8 are accurately fitted on the guiding rods 10, strictly limiting the clamping seats 8 to move linearly only on the axis of the guiding rods 10, i.e. in the horizontal direction.

[0047] Please refer to Figure 2 , the outside of the adjusting rod 11 is provided with a length scale.

[0048] It should be noted that when the operator is clamping, he can observe the same scale position on the two adjusting rods 11 to determine whether the two clamping seats 8 move synchronously and symmetrically by the same distance.

[0049] Please refer toFigure 2 The adjusting knob 12 is arranged on one end of the adjusting rod 11 outside the groove 7, and the outer side of the adjusting knob 12 is equidistantly provided with anti-skid convex strips.

[0050] It should be noted that the adjusting knob 12 can control the rotation of the adjusting rod 11 by rotating, and the anti-skid convex strips arranged on the outer side of the adjusting knob 12 significantly increase the friction coefficient of the contact surface of the hand and the adjusting knob 12. When the operator pinches and rotates the knob, the convex strips can effectively prevent the fingers from slipping and ensure that the force is efficiently converted into rotary motion.

[0051] Please refer to Figure 7 The adjusting handle 27 is arranged on one end of the control rod 26 away from the arc-shaped connecting rod 25.

[0052] It should be noted that the adjusting handle 27 is arranged to facilitate the operator to hold the hand and control the control rod 26.
