[0003] Chinese patent CN210572681U discloses a wire harness continuity testing workbench, including a workbench body, a test panel, and sliding plates. The workbench body is shaped like a ramp, and a recessed mounting cavity is provided on the ramp of the workbench body. The test panel is installed at the opening of the mounting cavity. The test panel has multiple test ports for connecting wire harnesses, and none of the test ports protrude from the ramp of the workbench body. Two parallel sliding grooves are provided on the ramp of the workbench body at the upper and lower ends of the test panel. There are two sliding plates, and sliding blocks are provided at the upper and lower ends of the two sliding plates. The sliding blocks are installed in the sliding grooves. During testing, the two sliding plates are pushed to slide to the sides to expose the test ports for easy connection of the wire harness. After testing, the two sliding plates are pushed to slide to the center to close and cover the test panel.

[0004] In related technologies, the terminal at one end of the wire harness to be tested is plugged into the test port on the test panel, and the wire harness is removed from the test port after the test is completed.

[0005] Regarding the aforementioned technologies, the inventors believe that manual plugging and unplugging is inefficient, and that manual plugging and unplugging can easily damage the test socket and the inside of the wire harness, thus affecting the normal use of the wire harness. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a testing device for wire harnesses, which solves the technical problem that manual plugging is inefficient and that manual plugging and unplugging can easily cause damage to the test socket and the inside of the wire harness, thus hindering the normal use of the wire harness.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A testing device for wire harnesses includes: a frame for supporting the testing device; a high-voltage testing machine mounted on the frame, the high-voltage testing machine having test ports formed thereon, at least two test ports spaced apart on the high-voltage testing machine, and the test ports being distributed in an even-numbered array; and clamping blocks, two clamping blocks disposed opposite each other on one side of a corresponding test port, the two clamping blocks being used to clamp one end of the wire harness.

[0009] A clamping assembly, mounted on the frame, is used to drive the clamping block to clamp the wire harness; a sliding assembly, mounted on the frame, is used to drive the clamping block to slide on the frame.

[0010] Furthermore, the clamping assembly includes a clamping cylinder mounted on the frame, and the piston rod of the clamping cylinder is connected to one of the clamping blocks.

[0011] Furthermore, each of the two clamping blocks has an installation groove on one side that is close to each other. A positioning block is installed in the installation groove, and a clamping groove is provided on the positioning block. The clamping groove on the positioning block is open.

[0012] Furthermore, a guide slope is formed on the positioning block, and the guide slope is inclined toward the inside of the clamping groove.

[0013] Furthermore, the sliding assembly includes a sliding cylinder mounted on the frame, which drives the clamp to move toward the side closer to the test port.

[0014] Furthermore, a laser marking machine is mounted on the frame, and a marking port is formed on the laser marking machine, with the marking port facing the side close to the clamping block.

[0015] Furthermore, the sliding assembly also includes a marking cylinder, which is mounted on the frame and drives the clamping block to slide toward or away from the laser marking machine.

[0016] In summary, this application includes at least one of the following beneficial technical effects of a wire harness testing device:

[0017] 1. Place both ends of the wire harness connector to be tested between the two sets of clamping blocks. The clamping assembly clamps the wire harness through the clamping blocks. Then, the sliding assembly moves the clamping blocks closer to the test socket of the high-voltage tester, so that the end of the wire harness can be inserted into the test socket. By clamping one end of the wire harness with the clamping assembly and the sliding assembly, manual insertion and removal of the wire harness can be eliminated, reducing the damage to the test socket and the inside of the wire harness during the insertion and removal process, and reducing the damage to the wire harness during the test.

[0018] 2. By using a clamping cylinder and a sliding cylinder, one end of the wire harness can be aligned with the test plug, reducing damage to the test plug.

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a testing device for wire harnesses.

[0027] Reference Figures 1-2 A testing device for wire harnesses includes a frame 1, on which a high-voltage tester 2 is mounted. The high-voltage tester 2 has test ports 211 formed on it, with at least two test ports 211 spaced apart. In use, both ends of the wire harness are plugged into the two test ports 211 respectively, forming a circuit between the wire harness and the high-voltage tester 2. The frame 1 is equipped with clamping blocks 3, a clamping assembly 4, and a sliding assembly 5. Two clamping blocks 3 are spaced apart. The clamping assembly 4 drives the two clamping blocks 3 to clamp the wire harness, and the sliding assembly 5 moves the clamping blocks 3 towards or away from the test ports 211.

[0028] A laser marking machine 11 is installed on the side of the frame 1 closest to the high-voltage testing machine 2. The laser marking machine 11 has a marking nozzle 12 facing towards the clamping block 3. After the wire harness passes inspection, the laser marking machine 11 marks the wire harness. To improve the marking effect of the laser marking machine 11, a slider 13 is installed on the frame 1. The slider 13 is vertically slidable on the frame 1, and the laser marking machine 11 is mounted on the slider 13. The laser marking machine 11 adjusts the marking distance between itself and the clamping block 3 via the slider 13, thereby improving the efficiency of the laser marking machine 11.

[0029] To improve the ease of raising and lowering the slider 13 on the frame 1, a screw 14 is rotatably mounted on the frame 1. One end of the screw 14 passes through the slider 13, and the slider 13 is threadedly connected to the screw 14. In use, the position of the slider 13 on the frame 1 can be adjusted by rotating the screw 14, greatly improving the ease of sliding the slider 13 on the frame 1.

[0030] Reference Figure 2 The sliding assembly 5 includes a first slide rail 51, which is mounted on the frame 1. Two first slide rails 51 are spaced apart on the frame 1 and are arranged in parallel. A first slide plate 511 is provided between the two first slide rails 51. The first slide plate 511 is rectangular in shape, and its two sides in the width direction are slidably mounted on the two first slide rails 51 respectively.

[0031] The sliding assembly 5 includes a marking cylinder 52, which is horizontally mounted on the frame 1. The piston rod of the marking cylinder 52 is connected to the first sliding plate 511. In use, the marking cylinder 52 drives the first sliding plate 511 to slide along the first slide rail 51 between the high-pressure testing machine 2 and the laser marking machine 11. When the wire harness is properly spaced on the first sliding plate 511, the wire harness moves with the first sliding plate 511 to the lower side of the laser marking machine 11, whereby the laser marking machine 11 marks the qualified wire harness.

[0032] A test platform 21 is provided on the first slide plate 511. Two test ports 211 are spaced apart on the test platform 21. The two test ports 211 are connected to the high voltage tester 2 by wires. In order to prevent the wires from affecting the sliding of the test platform 21 along the first slide plate 511, the length of the wire between the test platform 21 and the high voltage tester 2 is greater than the moving distance of the test platform 21 on the first slide rail 51.

[0033] Furthermore, there are at least two test ports 211 spaced apart on the test bench 21, and the test ports 211 are arranged in an even number of rows on the test bench 21. Preferably, this application only provides two test ports 211. In use, the two ends of the wire harness to be tested are plugged into the two test ports 211, and the high voltage tester 2 forms a circuit through the wire harness.

[0034] Reference Figure 2 A second slide plate 531 is provided on the first slide plate 511, and a second slide rail 53 is provided on the first slide plate 511. The length direction of the second slide rail 53 is perpendicular to the wire harness insertion test socket 211. The second slide plate 531 is slidably mounted on the second slide rail 53. The sliding assembly 5 includes a sliding cylinder 54, which is mounted on the first slide plate 511, and the piston rod of the sliding cylinder 54 is connected to the second slide plate 531. In use, the sliding cylinder 54 drives the second slide plate 531 to move towards the side away from the test socket 211.

[0035] Reference Figure 3 Two clamping blocks 3 are spaced apart on one side near the corresponding test port 211. One clamping block 3 is fixedly installed on the second slide plate 531, and the other clamping block 3 is slidably installed on the second slide plate 531. The two clamping blocks 3 are arranged opposite each other. When in use, the two clamping blocks 3 clamp the wire harness.

[0036] To improve the convenience of clamping the wire harness by clamping blocks 3, clamping assembly 4 includes clamping cylinder 41, which is mounted on the second slide plate 531. The piston rod of clamping cylinder 41 is connected to clamping blocks 3 that slide on the second slide plate 531. In use, clamping cylinder 41 drives two clamping blocks 3 to clamp the wire harness.

[0037] During use, different wire harnesses have varying end sizes. To improve the stability of the clamping blocks 3 in clamping the wire harness, mounting grooves 31 are provided on the sides of the two clamping blocks 3 that are close to each other. Positioning blocks 32 are installed within the mounting grooves 31 of both clamping blocks 3, and the positioning blocks 32 are locked onto the clamping blocks 3 with bolts. Clamping slots 33 are also provided on both clamping blocks 3, and the two adjacent positioning blocks 32 clamp the wire harness within the clamping slots 33. During use, operators can select the corresponding positioning block 32 according to different wire harness models, greatly improving the stability during wire harness testing.

[0038] Furthermore, both positioning blocks 32 have guide slopes 34, which are inclined towards the inner side near the clamping groove 33. During use, the guide slopes 34 guide the wire harness, improving the ease with which the positioning blocks 32 clamp the wire harness. In addition, after the end of the wire harness is clamped, the clamping force of the positioning blocks 32 acts on the wire harness. To reduce indentations left by the positioning blocks 32 on the wire harness, rubber pads 35 are provided in the clamping grooves 33 of the two positioning blocks 32. When the positioning blocks 32 clamp the wire harness, the rubber pads 35 press against the wire harness, causing them to deform. The rubber pads 35 not only reduce damage to the wire harness caused by the positioning blocks 32, but also increase the clamping force of the positioning blocks 32 on the wire harness, thus improving the stability of the wire harness when inserted into the test socket 211.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
