Description

Technical Field

[0001] This utility model relates to the field of cable testing auxiliary equipment technology, specifically to a clamping structure for wire harness testing. Background Technology

[0002] During wire harness inspection, the wire harness needs to be straightened and fixed. In traditional wire harness inspection clamping scenarios, due to the wide variety of wire harness specifications and large differences in thickness, the existing clamping structure can only adapt to wire harnesses of a specific size range. When faced with wire harnesses of different thicknesses, it is necessary to frequently change the matching clamps. This not only increases the complexity and cumbersomeness of the operation, but also reduces clamping efficiency, making it difficult to carry out the inspection work efficiently.

[0003] To address this issue, we propose a clamping structure for wire harness testing. Utility Model Content

[0004] The purpose of this invention is to provide a clamping structure for wire harness testing to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping structure for wire harness detection, comprising two rectangular boxes, with two parallel rubber rollers mounted on the inner walls of both sides of the two rectangular boxes via openings and rotating shafts. The outer walls of the rubber rollers are in contact with each other, and the outer walls of the rubber rollers have equally spaced annular pressure grooves. A synchronous gear disk is fixedly mounted on the outer wall of one end of the rubber roller via a rotating shaft, and a first knob is fixedly mounted on the other end of the rubber roller via a rotating shaft.

[0006] Preferably, the inner diameter of the equally spaced annular pressure grooves increases progressively.

[0007] Preferably, an inlet / outlet is provided on one side of the outer wall of the adjacent synchronous gear disk, and the inlet / outlet is located on the same straight line as the contact area of ​​the adjacent rubber rollers.

[0008] Preferably, a first fixing block and a second fixing block are fixedly provided on the bottom outer walls of the two rectangular boxes respectively. A rotating hole is opened at the center of one side outer wall of the first fixing block, and an external threaded rotating rod is movably connected to the inner wall of the rotating hole through a bearing. A threaded hole is opened at the center of one side outer wall of the second fixing block, and the outer wall of the external threaded rotating rod is threadedly connected to the inner wall of the threaded hole.

[0009] Preferably, a second knob is fixedly provided on the outer wall of one end of the externally threaded rotating rod.

[0010] Preferably, two parallel guide rods are fixedly provided on the outer wall of one end of the first fixing block, and the two guide rods are respectively located on both sides of the external threaded rotating rod. Two guide holes are opened on the outer wall of the second fixing block, and the outer wall of the guide rod and the inner wall of the guide hole are slidably connected.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] By turning the first knob, the rubber roller rotates synchronously via the synchronous gear disc. The wire harness is pressed into the annular wire pressing groove as the rubber roller rotates, and the wire harness is clamped and fixed between the two rectangular boxes. The annular wire pressing groove with gradually increasing inner diameter on the rubber roller can accommodate wire harnesses of different thicknesses, which greatly improves the versatility and practicality of the clamping structure, avoids the trouble of frequently changing clamps due to differences in wire harness specifications, and saves time and costs.

[0022] Example 1

[0023] Refer to the instruction manual appendix Figure 1-4 A clamping structure for wire harness testing includes two rectangular boxes 1. Two parallel rubber rollers 2 are mounted on the openings of the inner walls on both sides of the two rectangular boxes 1 via a rotating shaft. The outer walls of the rubber rollers 2 are in contact with each other. The outer walls of the rubber rollers 2 have annular pressure grooves 3 distributed at equal intervals. The inner diameter of the annular pressure grooves 3 increases stepwise to accommodate wire harnesses of different thicknesses. A synchronous gear disk 4 is fixedly installed on the outer wall of one end of the rubber roller 2 via a rotating shaft, so that the synchronous gear disks 4 of the two rubber rollers 2 mesh with each other and the two rubber rollers 2 can rotate synchronously. At the other end of the rubber roller 2, a first knob 5 is fixedly installed via a rotating shaft for easy manual rotation of the rubber roller 2.

[0024] Example 2

[0025] Based on Embodiment 1, a first fixing block 7 and a second fixing block 8 are fixedly installed on the bottom outer walls of the two rectangular boxes 1, respectively. A rotating hole 9 is opened at the center of one side outer wall of the first fixing block 7, and an external threaded rotating rod 11 is movably connected to the inner wall of the rotating hole 9 through a bearing. A threaded hole 10 is opened at the center of one side outer wall of the second fixing block 8, and the outer wall of the external threaded rotating rod 11 is threadedly connected to the inner wall of the threaded hole 10. The distance between the two rectangular boxes 1 can be adjusted by rotating the external threaded rotating rod 11. A second knob 12 is fixedly installed on the outer wall of one end of the external threaded rotating rod 11 to facilitate manual operation of the external threaded rotating rod 11.

[0026] Example 3

[0027] Based on Embodiment 1, two parallel guide rods 14 are fixedly installed on the outer wall of one end of the first fixing block 7, and these two guide rods 14 are respectively located on both sides of the external threaded rotating rod 11; two guide holes 13 are opened on the outer wall of the second fixing block 8, so that the outer wall of the guide rod 14 and the inner wall of the guide hole 13 are slidably connected. In this way, when adjusting the distance between the two rectangular boxes 1, the guide rod 14 slides in the guide hole 13, which plays a guiding and stabilizing role. In addition, a wire inlet / outlet port 6 is opened on one side of the outer wall of the adjacent synchronous gear disk 4, and the wire inlet / outlet port 6 is located on the same straight line as the contact part of the adjacent rubber roller 2, which facilitates the entry and exit of the wire harness.

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual appendix Figure 1-4 When using this invention, the operator first selects a suitable groove from the annular pressure grooves 3 on the rubber roller 2, which have progressively larger inner diameters, according to the thickness of the wire harness to be tested. Then, the wire harness is placed into the inlet / outlet 6. The operator then manually rotates the first knob 5, which drives the connected rubber roller 2 to rotate. Since the two rubber rollers 2 rotate synchronously through the meshing of the synchronous gear disc 4, the wire harness gradually enters the selected annular pressure groove 3 under the rotation of the rubber roller 2. Under the squeezing action of the outer wall of the rubber roller 2, the wire harness is clamped and fixed between the two rectangular boxes 1. The operator only needs to manually rotate the second knob 12, which drives the external threaded rotating rod 11 to rotate in the rotating hole 9 of the first fixing block 7. At the same time, the external threaded rotating rod 11 rotates relative to the threaded hole 10 of the second fixing block 8. Under the guiding action of the sliding cooperation between the guide rod 14 and the guide hole 13, the two rectangular boxes 1 smoothly move closer or further apart until the required distance is reached, thus meeting the usage requirements of different wire harness testing scenarios.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
