[0002] Terminal pluggable test connection structure is a reusable electrical connection device used for electronic testing and measurement. It achieves a fast and reliable electrical connection between the test equipment and the unit under test through mechanical plugging and unplugging.

[0003] The existing terminal plug-in test connection structure has the following disadvantages during use:

[0004] Generally, the testing head of the testing instrument is fixed to the testing table with hot melt adhesive. The most common example is the main body of a wire harness comprehensive tester. One end of the wire harness plug is inserted into the testing head, which is then connected to the powered wire harness comprehensive tester main body. The test results are displayed on the front screen of the wire harness comprehensive tester main body. Then, the wire harness plug is manually inserted into the testing head to connect to the testing instrument for testing. However, it is necessary to accurately locate the front hole of the testing head during insertion, which wastes a lot of time. Sometimes, it is inevitable that the wire harness will be inserted incorrectly, resulting in a failure to connect quickly, which greatly reduces the efficiency of testing. Therefore, a terminal plug-in test connection structure is needed. Utility Model Content

[0005] The purpose of this invention is to provide a terminal plug-in test connection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a terminal plug-in test connection structure, including a test bench, a wire harness comprehensive tester body fixedly connected to the top of the test bench, a test head connected to the outside of the wire harness comprehensive tester body via a power cord, and a connection structure installed on the top of the test bench on the front side of the wire harness comprehensive tester body; the connection structure is used to facilitate plugging and unplugging of wire harness terminals into the test head.

[0007] In a preferred embodiment, the connection structure includes a mounting groove formed at the top of the test bench. The mounting groove has a convex vertical cross-section. A mounting base with a convex vertical cross-section is movably inserted into the mounting groove. A front limiting block is fixedly connected to the front side of the top of the mounting base, and a rear limiting block is fixedly connected to the rear side of the top of the mounting base.

[0008] In a preferred embodiment, the front limiting block and the rear limiting block are respectively provided with a first groove and a second groove, wherein the diameter of the first groove is larger than the diameter of the second groove.

[0009] In a preferred embodiment, a positioning sleeve fixed to the top of the mounting base is provided between the front limiting block and the rear limiting block. The vertical cross-section of the positioning sleeve is C-shaped. Both ends of the top of the positioning sleeve are provided with bent portions. Weakening grooves are provided on both sides of the middle of the inner bottom wall of the positioning sleeve. Multiple first lightweight grooves are provided on both outer arc walls of the positioning sleeve.

[0010] In a preferred embodiment, the front sidewall of the front limiting block is fixed to a conical inlet cylinder via an L-shaped connecting block, and the inlet cylinder has multiple second lightweight grooves arranged in a ring array.

[0011] In a preferred embodiment, clamping plates with an arc-shaped vertical cross-section are fixedly attached to both outer walls of the positioning sleeve. The bottom ends of the clamping plates are inserted into slots opened at the top of the test bench. The length of the slots is equal to the length of the clamping plates, and the width of the bottom cross-section of the clamping plates is smaller than the width of the slots.

[0012] Compared with the prior art, the terminal plug-in test connection structure provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the plug-in test connection structure, the mounting base is first inserted into the mounting groove during installation. Then, the detection head is inserted between the front and rear limiting blocks. During insertion, the two bent parts facilitate quick insertion of the detection head. The two curved walls of the positioning sleeve deform laterally through the weakening groove, causing the bottom of the clamping plate to be inserted into the corresponding slot. The length of the clamping plate is equal to the length of the slot, thus preventing the mounting base from wobbling back and forth and securing it. The mounting base is fixed to the test platform by the force of the detection head installed in the positioning sleeve, greatly improving the ease of installation of the connection structure. Furthermore, the guide tube allows the plug of the external wire harness to be quickly guided and inserted into the front socket of the detection head, avoiding misalignment and reduced testing efficiency during testing.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention. Example

[0021] Generally, the testing head 13 of the testing instrument is fixed to the testing table 1 with hot melt adhesive. The most common method is to use the main body 11 of the wire comprehensive testing machine. One end of the wire harness plug is inserted into the testing head 13 and connected to the powered wire comprehensive testing machine main body 11. The test results are displayed on the front screen of the wire comprehensive testing machine main body 11. Then, the plug of the wire harness is manually inserted into the testing head 13 to connect the testing instrument for testing. However, when inserting, it is necessary to accurately locate the front hole of the testing head 13. However, a lot of time is wasted in the alignment process. Sometimes, it is inevitable that the plug will be inserted crookedly, resulting in the inability to connect quickly, which greatly reduces the efficiency of testing.

[0022] For this purpose, please refer to Figure 1-3 This utility model provides a terminal plug-in test connection structure, including: a test bench 1, a wire harness integrated tester body 11 fixedly connected to the top of the test bench 1, a test head 13 connected to the outside of the wire harness integrated tester body 11 via a power cord 12, and a connection structure installed on the top of the test bench 1 on the front side of the wire harness integrated tester body 11; the connection structure is used to conveniently plug and unplug wire harness terminals into the test head 13.

[0023] The main body 11 of the wire comprehensive testing machine is existing technology. The specific working principle will not be described in detail, but can be found on Baidu. The front end of the testing head 13 is provided with a round hole-shaped insertion hole to facilitate the insertion of the plug end of the wire harness. The plug end is cylindrical.

[0024] Further as Figure 1-3 As shown, it is worth noting that, in order to allow the plug end of the wire harness to be quickly inserted into the front socket of the detection head 13, a connection structure is provided, including a mounting groove on the top of the test bench 1. The vertical cross-section of the mounting groove is convex. A mounting base 21 with a convex vertical cross-section is movably inserted into the mounting groove. A front limiting block 22 is fixedly connected to the front side of the top of the mounting base 21, and a rear limiting block 23 is fixedly connected to the rear side of the top of the mounting base 21. A first support groove 221 and a second support groove 231 are respectively provided on the front limiting block 22 and the rear limiting block 23. The diameter of the first support groove 221 is larger than the diameter of the second support groove 231. A positioning clip 24 is fixed to the top of the mounting base 21 between the front limiting block 22 and the rear limiting block 23. The vertical cross-section of the positioning clip 24 is C-shaped. The positioning sleeve 24 has bent portions 241 at both ends of its top. The inner bottom wall of the positioning sleeve 24 has weakening grooves 243 on both sides of its inner wall. Multiple first lightweight grooves 242 are formed on the outer arc walls of both sides of the positioning sleeve 24. The front side wall of the front limiting block 22 is fixed to a conical guide cylinder 251 by an L-shaped connecting block 25. Multiple second lightweight grooves 252 are formed on the guide cylinder 251 in a ring array. A clamping plate 26 with an arc-shaped vertical cross section is fixed to the outer walls of both sides of the positioning sleeve 24. The bottom end of the clamping plate 26 is inserted into the slot 261 formed at the top of the test bench 1. The length of the slot 261 is equal to the length of the clamping plate 26. The width of the cross section at the bottom end of the clamping plate 26 is smaller than the width of the slot 261.

[0025] Among them, the appendix Figure 3The positioning sleeve 24 shown is in the state after the detection head 13 is inserted. When the detection head 13 is pulled out, its two bent parts 241 are brought into contact by the spring action of the two weakening grooves 243. The front limiting block 22 and the rear limiting block 23 are designed so that the detection head 13 will not move back and forth when inserted into the wire harness plug end. In addition, the width of the bottom cross-section of the clamping plate 26 is smaller than the width of the slot 261. This is so that the bottom of the clamping plate 26 can be easily inserted into the slot 261. When the detection... After the head 13 is pulled out, the outer arc walls on both sides of its positioning sleeve 24 are pulled out from the slots 261 by the rebound action of the two weakening grooves 243, so that the mounting base 21 can be easily removed from the test bench 1 for replacement. The first lightweight groove 242 is set to reduce the weight of the positioning sleeve 24, while the second lightweight groove 252 is set to reduce the weight of the inlet cylinder 251. The entire connecting structure is made of ABS plastic, which has low design cost and good performance.

[0026] In summary: When using this plug-in test connection structure, during installation, the mounting base 21 can be inserted into the mounting groove first, and then the detection head 13 can be inserted between the front limiting block 22 and the rear limiting block 23. During insertion, the two bending parts 241 facilitate quick insertion of the detection head 13, and both sides of the positioning sleeve 24 deform to the sides through the weakening groove 243, thereby driving the bottom end of the clamping plate 26 into the corresponding slot 261. The length of the mounting base 21 is equal to the length of the slot 261, thus preventing the mounting base 21 from wobbling back and forth and fixing it in place. The fixing between the mounting base 21 and the test table 1 is achieved by the force of the detection head 13 installed in the positioning clip 24, which greatly improves the ease of installation of the connection structure. Furthermore, with the help of the inlet tube 251, the plug of the external wire harness can be quickly guided and inserted into the front end socket of the detection head 13, thereby avoiding the problem of misalignment of the plug during testing, which reduces the testing efficiency.
