Description

Technical Field

[0001] This utility model relates to the technical field of wire harness continuity testing equipment, and in particular to a wire harness continuity tester with multiple wire end fixing function. Background Technology

[0002] Wire harnesses are an indispensable component of electronic devices, and their quality directly affects the performance and safety of the equipment. Ensuring the conductivity of wire harnesses is crucial during the manufacturing process. Therefore, continuity testing is a key step in wire harness production.

[0003] When operating the wire harness continuity testing workbench, both ends of the wire harness are plugged into the ports of the testing workbench, and continuity testing is performed under computer control. This design can effectively detect the continuity of the wire harness, thereby avoiding the generation of defective products.

[0004] However, in order to ensure the stability of the wire harness during the testing process, it is necessary to use a fixing tool to fix the wire harness. Existing fixing tools usually adopt a detachable clamping rod design, such as the wire harness continuity testing workbench disclosed in Chinese Patent Publication No. "CN210572681 U", which can meet the needs of wire harness fixing to a certain extent.

[0005] However, due to the diverse locations where wire harnesses need to be fixed, existing clamping rods typically use threaded connections, which cannot achieve diverse changes and adaptations in clamping positions, resulting in poor fixing effects on wire harnesses. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where clamping rods typically use threaded connections, which prevent diverse changes in clamping positions and adaptability. This invention proposes a wire harness continuity tester with multi-wire end fixing function.

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

[0008] Design a wire harness continuity tester with multi-wire end fixing function, including a test stand and a support component connected to the test stand;

[0009] At least one rod is slidably connected to the support assembly, and at least one of the rods is connected and locked to the support assembly by fasteners.

[0010] At least one clamping assembly is slidably connected to the rod, the clamping assembly being used to fix the wires of the test port on the test bench, and the clamping assembly being fixed to the rod by a locking assembly.

[0011] Furthermore, the support assembly includes a base connected to the test bench, on which a rectangular rod is fixedly connected, with the other end of the rectangular rod extending freely.

[0012] Furthermore, a sliding sleeve is fixedly connected to the end of the rod, the sliding sleeve slides on the outside of the rectangular rod, and the fastener is connected to the outside of the sliding sleeve.

[0013] Furthermore, the clamping assembly includes a sleeve, and a clamping block is movably inserted into the inner side of the sleeve by a spring;

[0014] The sleeve and the clamping block have a clamping port in the middle, and the sleeve and the clamping block have wire inlets on their sides, which are connected to the clamping ports.

[0015] Furthermore, the side of the clamping block is fitted with positioning glass beads, which stop in the clamping opening of the sleeve.

[0016] Furthermore, the locking assembly includes symmetrically formed bent plates on both sides of the top of the sleeve, and a sliding groove is provided on the end face of the rod. The two bent plates are slidably connected in the sliding groove, wherein the top bent edge of the bent plate stops on the upper side of the rod.

[0017] Furthermore, it also includes a screw threaded onto the sleeve, the top of which has a frustum portion that abuts against the two bent plates as they deform outward to abut against the inner wall of the groove.

[0018] Furthermore, the bending plate is an elastic element formed on the end face of the sleeve, and the elastic element has an L-shaped structure.

[0019] The present invention proposes a wire harness continuity tester with multi-wire-end fixing function. The advantages are as follows: By adopting a sliding connection rod design, multiple rods can be assembled according to the position of the test port during testing. Each rod is equipped with multiple clamping components to clamp and fix the wire harness, thus ensuring the stability of the wire harness connector when inserted into the test port. At the same time, the position of the clamping components is adjustable to meet the fixing requirements of different positions, thereby further improving the adaptability of the wire harness during fixing. The overall structure design is simple and greatly improves the fixing stability of the connector during wire harness testing. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 As an embodiment of this utility model, a wire harness continuity tester with multi-wire end fixing function is disclosed. Specifically, the tester includes a test platform 1 and a support component 2 connected to the test platform 1. Of course, the test platform 1 is provided with several test ports. During testing, the two ends of the wire harness are inserted into two matching ports to realize the continuity detection of the wire harness. Its specific structure and principle have been disclosed in the prior art, and will not be described in detail here.

[0028] At least one rod 3 is slidably connected to the support assembly 2, and at least one rod 3 is connected and locked to the support assembly 2 by a fastener 31.

[0029] At least one clamping component 4 is slidably connected to the rod 3. The clamping component 4 is used to fix the wire of the test port on the test bench 1. The clamping component 4 is fixed to the rod 3 by a locking component 5.

[0030] In some embodiments, the support component 2 of this utility model includes a base 21 connected to the test bench 1, and a rectangular rod 22 is fixedly connected to the base 21. The other end of the rectangular rod 22 extends freely. Specifically, in this embodiment, the rectangular rod 22 can be set as a pentagonal rod. The rod 3 can slide freely on the rectangular rod 22 to achieve circumferential locking. Of course, those skilled in the art know that multiple rods 3 can also be set, and their straight positions can be adjusted to meet the wire fixing requirements of test ports at different positions.

[0031] Based on the above embodiments, in this embodiment, the end of the rod 3 is fixedly connected to a sliding sleeve, which slides on the outside of the rectangular rod 22. The fastener 31 is connected to the outside of the sliding sleeve. Preferably, the fastener 31 in this embodiment is a bolt. That is, when it is necessary to fix the wire end of the wire harness, the rod 3 can be moved to the required position, and then the bolt thread is used to connect the sliding sleeve to abut against the outside of the rectangular rod 22 to complete the linear position fixation of the rod 3.

[0032] In some embodiments, the clamping assembly 4 of the present invention includes a sleeve 41, and a clamping block 43 is movably inserted into the inner side of the sleeve 41 by means of a spring 42.

[0033] The sleeve 41 and the clamping block 43 have a clamping port 44 in the middle, and the sleeve 41 and the clamping block 43 are provided with a wire inlet 45 on the side, and the wire inlet 45 is connected to the clamping port 44.

[0034] In this embodiment, when it is necessary to fix the wire harness at the test port, the lateral position of the rod 3 and the longitudinal position of the clamping assembly 4 are first fixed. After the fixing is completed, the wire harness at the wire end is inserted into the clamping port 44 of the clamping block 43 along the sleeve 41 and the wire inlet 45 of the clamping block 43. After the wire harness is inserted, the pressure on the clamping block 43 is released. At this time, under the push of the spring 42, the clamping block 43 moves outward. By changing the space between the clamping block 43 and the clamping port 44 in the sleeve 41, the wire harness at the wire end is clamped and fixed.

[0035] Of course, in order to assemble and disassemble the clamping block 43, a positioning glass bead 46 is embedded on the side of the clamping block 43 in this embodiment. The positioning glass bead 46 stops in the clamping port 44 of the sleeve 41. The positioning glass bead 46 is existing technology. When it is necessary to wash the clamping block 43, the entire clamping block 43 can be taken out by pressing the telescopic end of the positioning glass bead 46 inward. The operation is simple and convenient.

[0036] Furthermore, in this embodiment of the present invention, the locking component 5 includes symmetrically formed bent plates 51 on both sides of the top of the sleeve 41, and a sliding groove 32 is provided on the end face of the rod 3. The two bent plates 51 are slidably connected in the sliding groove 32, wherein the top bent edge of the bent plate 51 stops on the upper side of the rod 3.

[0037] It should be noted that the bending plate 51 described in this embodiment is an elastic element formed on the end face of the sleeve 41. In this embodiment, the bending plate 51 is preferably made of plastic. Of course, the elastic element in this embodiment has an L-shaped structure. The purpose of adopting the L-shaped structure is to stop the downward movement of the sleeve 41 and ensure that the sleeve 41 can slide in the slide groove 32 with the two bending plates 51. In addition, since the bending plate 51 described in this embodiment is designed as an elastic element, when the ends of the two bending plates 51 are pressed, they can be deformed and contracted inward. This allows the entire clamping assembly 4 to be disassembled. During installation, the two bending plates 51 are inserted upward along the bottom of the slide groove 32 until the bending plates 51 pop out and are locked on the upper side of the rod 3. This achieves the installation and positioning of the clamping assembly 4. In other words, the clamping assembly 4 described in this embodiment is freely detachable to meet the fixing requirements of different numbers of wire ends.

[0038] Based on the above embodiments, this embodiment also includes a screw 52 threadedly connected to the sleeve 41. The top of the screw 52 has a frustum 53. The frustum 53 abuts against the two bending plates 51 and deforms outward to abut against the inner wall of the slide groove 32. That is, when it is necessary to fix the clamping assembly 4, it is first slid and moved to the required position. Then the screw 52 is rotated. When the screw 52 moves downward, its outer frustum 53 abuts against the two bending plates 51 and deforms. Since the bending plates 51 abut against the inner wall of the slide groove 32, the position of the clamping assembly 4 can be fixed to improve the fixing stability of the wire harness.

[0039] In summary, by employing a sliding connection rod 3, this utility model allows for the assembly of multiple rods 3 according to the position of the test port during testing. Each rod 3 is equipped with multiple clamping components 4, which can clamp and fix the wire harness, thus ensuring the stability of the wire harness connector when inserted into the test port. At the same time, the position of the clamping components 4 is adjustable to meet the fixing requirements at different positions, further improving the adaptability of the wire harness during fixing. The overall structural design is simple and greatly improves the fixing stability of the connector during wire harness testing.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
