Description

Technical Field

[0001] This application relates to the technical field of wire harness terminal tensile testing, and in particular to a wire harness terminal tensile testing device. Background Technology

[0002] Wire harness terminals are wiring terminals used in electrical connections to transmit electrical signals or conduct electricity. They are commonly found in the connection of batteries, wires, and equipment.

[0003] However, in practical applications, most existing wire harness terminals have different lengths when performing tightness tests, which requires the use of different torque testers. This leads to certain limitations in their use and hinders their widespread adoption.

[0004] Therefore, those skilled in the art have provided a wire harness terminal tensile testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problem mentioned in the background art that the different lengths of wire harness terminals necessitate the use of different torque testers, which limits their application and hinders widespread adoption, this application provides a wire harness terminal tensile testing device.

[0006] The wire harness terminal tensile testing device provided in this application adopts the following technical solution: it includes a base plate, a limiting rod is fixedly connected to the center of the top side of the base plate, a first fixing block and a second fixing block are fixedly connected to the top side of the base plate, a third fixing block and a fourth fixing block are slidably sleeved on the outer side of the limiting rod, a detection connecting bolt is fixedly connected to the top side of the first fixing block and the third fixing block, a tensile gauge is fixedly connected to the left side of the fourth fixing block, the detection end of the tensile gauge is fixedly installed to the right side of the third fixing block, a threaded rod is fixedly connected to the right side of the fourth fixing block, a threaded sleeve is rotatably connected to the left side of the second fixing block, and the threaded rod is threadedly connected to the inner wall of the threaded sleeve.

[0007] Preferably, two T-shaped limiting rods are fixedly connected to the top side of the base plate, the two T-shaped limiting rods are symmetrically distributed, and the third fixing block and the fourth fixing block are slidably sleeved with the two T-shaped limiting rods.

[0008] Preferably, a hexagonal transmission sleeve is fixedly fitted on the outer side of the threaded sleeve.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting up a tension gauge, the two ends of the wire harness terminal are respectively fitted onto two test connectors. The threaded sleeve is manually and continuously turned. When the threaded sleeve rotates, it drives the threaded rod to move laterally along the direction of the threads. The movement of the threaded rod drives the fourth fixing block to move to the right. The fourth fixing block, in conjunction with the tension gauge, drives the third fixing block to move to the right. At this time, as the third fixing block moves to the right, the installed wire harness terminal will gradually tighten. Meanwhile, the tension gauge is continuously observed. When the pointer on the tension gauge points to the qualified scale and the wire harness terminal has not broken, the quality of the current wire harness terminal can be inferred to be qualified. This method can meet the testing needs of wire harness terminals of different lengths, effectively reducing the limitations in the use process and facilitating its widespread use.

[0019] The following will be combined with the appendix Figure 1-4The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application discloses a wire harness terminal tensile testing device, referring to... Figure 1-4 The system includes a base plate 1, a limit rod 2 fixedly connected to the center of the top side of the base plate 1, a first fixing block 3 and a second fixing block 4 fixedly connected to the top side of the base plate 1, a third fixing block 5 and a fourth fixing block 6 slidably sleeved on the outer side of the limit rod 2, detection connecting bolts 10 fixedly connected to the top sides of the first fixing block 3 and the third fixing block 5, a tension gauge 7 fixedly connected to the left side of the fourth fixing block 6, the detection end of the tension gauge 7 fixedly installed to the right side of the third fixing block 5, a threaded rod 8 fixedly connected to the right side of the fourth fixing block 6, a threaded sleeve 9 rotatably connected to the left side of the second fixing block 4, and a threaded drive connection between the threaded rod 8 and the inner wall of the threaded sleeve 9; by setting the tension gauge 7, the two ends of the wire harness terminal are respectively sleeved on the two detection bolts 10. On the test connector 10, manually and continuously tighten the threaded sleeve 9. When the threaded sleeve 9 rotates, it drives the threaded rod 8 to move laterally along the direction of the threads. The movement of the threaded rod 8 drives the fourth fixing block 6 to move to the right. The fourth fixing block 6, in conjunction with the tension gauge 7, drives the third fixing block 5 to move to the right. At this time, as the third fixing block 5 moves to the right, the installed wire harness terminal will gradually tighten. Meanwhile, the tension gauge 7 is continuously observed. When the pointer on the tension gauge 7 points to the qualified scale and the wire harness terminal is not broken, the quality of the current wire harness terminal can be inferred to be qualified. This method can meet the testing needs of wire harness terminals of different lengths, effectively reducing the limitations in the use process and facilitating its widespread use.

[0021] In this application, two T-shaped limiting rods 11 are fixedly connected to the top side of the base plate 1. The two T-shaped limiting rods 11 are symmetrically distributed. The third fixing block 5 and the fourth fixing block 6 are slidably sleeved with the two T-shaped limiting rods 11. By setting the T-shaped limiting rods 11, when the third fixing block 5 and the fourth fixing block 6 move, the two T-shaped limiting rods 11 cooperate with each other to form a limit, thereby ensuring that the third fixing block 5 and the fourth fixing block 6 move in the horizontal direction and avoid deviation.

[0022] In this application, a hexagonal transmission sleeve 12 is fixedly mounted on the outer side of the threaded sleeve 9; by setting the hexagonal transmission sleeve 12, when the threaded sleeve 9 is turned, the hexagonal transmission sleeve 12 can be used to easily turn it with tools, thereby achieving the purpose of saving effort.

[0023] In this application, a groove is provided on the top side of the limiting rod 2, and a measuring scale 13 is fixedly installed on the inner wall of the groove. By setting the measuring scale 13, when the pointer on the tension gauge 7 points to the qualified scale line, the distance between the third fixed block 5 and the fourth fixed block 6 can be determined by observing the measuring scale 13. In this way, the torque of the qualified tension can be obtained, thereby obtaining diverse test data.

[0024] In this application, the tops of both detection connectors 10 are rounded; by setting the tops of the detection connectors 10 to be rounded, the convenience of assembling the wire harness terminals and the detection connectors 10 can be improved.

[0025] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] The implementation principle of the wire harness terminal tensile testing device in this application embodiment is as follows: In use, the two ends of the wire harness terminal are respectively fitted onto two testing connectors 10. The threaded sleeve 9 is manually and continuously turned. As the threaded sleeve 9 rotates, it drives the threaded rod 8 to move laterally along the direction of the threads. The movement of the threaded rod 8 causes the fourth fixing block 6 to move to the right. The fourth fixing block 6, in conjunction with the tensile gauge 7, drives the third fixing block 5 to move to the right. At this time, as the third fixing block 5 moves to the right, the installed wire harness terminal will gradually tighten. Simultaneously, the tensile gauge 7 is continuously observed. When the pointer on the tensile gauge 7 points to the qualified scale and the wire harness terminal has not broken, the quality of the current wire harness terminal can be inferred to be qualified. This method can meet the testing needs of wire harness terminals of different lengths. It effectively reduces the limitations in the use process and is conducive to the promotion of use. When the third fixing block 5 and the fourth fixing block 6 move, the two T-shaped limit rods 11 cooperate with each other to form a limit, thereby ensuring that the third fixing block 5 and the fourth fixing block 6 move in a horizontal direction and avoid deviation. When tightening the threaded sleeve 9, the hexagonal transmission sleeve 12 can be used to easily tighten it with tools, thereby saving effort. When the pointer on the tension gauge 7 points to the qualified scale line, observe the measuring ruler 13 to determine the distance between the third fixing block 5 and the fourth fixing block 6, thereby obtaining the torque of the qualified tension and thus obtaining diverse test data. The top of the test connector 10 is designed with rounded corners, which can improve the convenience of fitting the wire harness terminal and the test connector 10 together.
