[0002] In electrical engineering, to facilitate installation and maintenance and ensure the normal use of electrical equipment during high-voltage power transmission, it is sometimes necessary to arrange and bundle the wires of different colors and specifications of the electrical equipment in a reasonable manner.

[0003] Connectors are typically used to connect wire harnesses to each other and to electrical equipment. It is essential to ensure the connection strength between the connector's mounting interface and the wire harness to prevent the wire harness from coming loose during operation, which could cause short circuits or damage to the electrical equipment. Therefore, it is necessary to test the connection strength between the connector and the wire harness before use. Existing testing equipment usually performs the test by pulling, and the results are obtained using a tensile gauge. However, the rapid change in tensile force during the pulling process creates an impact that significantly affects the test results, making them inaccurate. Utility Model Content

[0006] A high-voltage wire harness connector testing device includes a base plate and a placement plate. The base plate is supported on a support column, and a fixing mechanism is provided on one side of the base plate. The fixing mechanism includes a mounting plate, and slide rails are provided on both sides of the mounting plate. Rollers are provided below the placement plate, and the rollers form a rolling connection within the slide rails. A connector is placed on the placement plate, and a fixing interface is provided on both sides of the connector. One end of a cable is connected to the fixing interface, and the cable passes through a support frame. A V-shaped groove is provided on the support frame, and a placement through hole is provided at the bottom of the groove. The other end of the cable is clamped on a head clamping assembly, which is hung on a tension gauge. A display screen is provided on the tension gauge, and a hook is provided on one side of the tension gauge. A pull rope is attached to one end of the tension gauge away from the head clamping assembly. The pull rope is wound around a wire roller, which is placed vertically and its two ends are rotatably connected to an F-shaped bracket. The F-shaped bracket is fixedly connected to the base plate.

[0007] Furthermore, limiting plates A and B are provided on both sides above the placement plate, and limiting plates A and B are respectively locked on both sides of the connector; a limiting hole along the slide rail direction is opened at the bottom of the placement plate, and a limiting rod is inserted into the limiting hole, with both ends of the limiting rod fixedly connected to the mounting plate.

[0008] Furthermore, the head clamping assembly includes two clamping plates, with one end of the cable clamped in the middle of the clamping plates. Each clamping plate is provided with a movable block, which is rotatably connected to a hinge block. A hook is provided on the hinge block, and the hook is hooked onto the hook of the tension gauge.

The fastening plates are fixedly connected to each other by fastening bolts.

[0009] Furthermore, a drive mechanism is provided below the wire roller. The drive mechanism includes a sprocket A, the shaft of which passes through the base plate and is fixedly connected to the bottom of the wire roller. A hinge is wrapped around the sprocket A, and a sprocket B is also wrapped around the hinge. A shaft is provided at the center of the sprocket B, and the shaft is supported by an L-shaped bracket. A bevel gear A is provided on the shaft, and the bevel gear A meshes with the bevel gear B. A rotating shaft is fixedly connected to the center of the bevel gear B. One end of the rotating shaft is supported on a side support plate, and the other end is fixedly connected to a motor.

[0010] Furthermore, a braking mechanism is provided on one side of the sprocket A. The braking mechanism includes a slider, which is slidably connected to a groove.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a high-voltage wire harness connector testing device, including a base plate 1 and a placement plate 5; the base plate 1 is supported on a support column 2, and a fixing mechanism is provided on one side of the upper part of the base plate 1, the fixing mechanism including a mounting plate 3, and slide rails 4 are provided on both sides of the mounting plate 3; rollers 6 are provided below the placement plate 5, and the rollers 6 form a rolling connection within the slide rails 4; a connector 7 is placed on the placement plate 5, and a fixing interface is provided on both sides of the connector 7, with one end of a cable 12 connected to the fixing interface, the cable 12 passing through a support frame 13, and the support frame 13... The cable 12 has a V-shaped groove on the top, and a perforation hole at the bottom of the groove. The other end of the cable 12 is clamped on the head clamping assembly 14, which is hung on the tension gauge 15. The tension gauge 15 has a display screen 151 and a hook 152 on one side. One end of the tension gauge 15 away from the head clamping assembly 14 is tied with a pull rope 16, which is wound around the roller 17. The roller 17 is placed vertically and its two ends are rotatably connected to the F-shaped bracket 18. The F-shaped bracket 18 is fixedly connected to the base plate 1.

[0026] Among them, such as Figure 3 As shown, limiting plates A8 and B9 are provided on both sides above the placement plate 5, and the limiting plates A8 and B9 are respectively locked on both sides of the connector 7 to prevent the connector 7 from detaching from the placement plate 5 along with the cable 12 when the cable 12 is pulled; a limiting hole 10 is opened at the bottom of the placement plate 5 along the direction of the slide rail 4, and a limiting rod 11 is inserted into the limiting hole 10. The two ends of the limiting rod 11 are fixedly connected to the mounting plate 3 to prevent the roller 6 from detaching from the slide rail 4 when the cable 12 is pulled; the fixing mechanism ensures that the cable 12 is always in a straight state to avoid the influence of the weight of the cable 12 on the connection strength test.

[0027] Among them, such as Figure 3 As shown, the head clamping assembly 14 includes two clamping plates 141, with one end of the cable 12 clamped in the middle of the clamping plates 141. Each clamping plate 141 is provided with a movable block 142, which is rotatably connected to a hinge block 143. A hook 144 is provided on the hinge block 143, and the hook 144 hooks onto the hook 152 of the tension gauge 15. The clamping plates 141 are provided with dense barbs 145, and a fastening plate 146 is provided on the outer side of the clamping plates 141 away from the movable block 142. The fastening plates 146 are fixedly connected to each other by fastening bolts. The barbs 145 in the clamping plates 141 of the head clamping assembly 14 hold the cable 12 in place to prevent it from falling off during the tensile test. Moreover, the head clamping assembly 14 has a simple structure and is easy to operate.

[0028] Among them, such as Figure 5As shown, a drive mechanism is provided below the wire roller 17. The drive mechanism includes a sprocket A19. The shaft of the sprocket A19 passes through the base plate 1 and is fixedly connected to the bottom of the wire roller 17. A hinge 20 is surrounded on the sprocket A19, and a sprocket B21 is also surrounded on the hinge 20. A shaft is provided at the center of the sprocket B21. The shaft is supported by an L-shaped bracket 22. A bevel gear A23 is provided on the shaft. The bevel gear A23 meshes with a bevel gear B24. A rotating shaft 25 is fixedly connected to the center of the bevel gear B24. One end of the rotating shaft 25 is supported on the side support plate 26, and the other end is fixedly connected to the motor 27. The circumference of the sprocket A19 is significantly larger than that of the sprocket B21, which helps to slow down the rotation speed. The motor 27 drives the tension gauge 15 and the cable 12 to pull slowly and continuously increase the tension until the cable 12 is dislodged from the fixed interface of the connector 7. The maximum connection strength between the connector 7 and the cable 12 can be measured.

[0029] Among them, such as Figure 5 As shown, a braking mechanism is provided on one side of the sprocket A19. The braking mechanism includes a slider 28, which is slidably connected to the groove 29. A braking rubber block 30 is connected to the side of the slider 28 facing the sprocket A19. One end of the connecting rod 31 is rotatably connected to the slider 28, and the other end of the connecting rod 31 is rotatably connected to the handle 32. The center of the handle 32 is rotatably connected to the base plate 1. A grip 33 is fixedly connected to the outer wall of one side of the handle 32. Pushing the grip 33 causes the handle 32 to rotate, and the connecting rod 31 pushes the slider 28 to slide in the groove 29. The braking rubber block 30 contacts the sprocket A19 and applies a certain pressure. The roller 17 stops rotating, and the tension acting on the cable 12 no longer increases. At this time, the reading on the display screen 151 of the tension gauge 15 is the tension strength borne by the cable 12. If the cable 12 does not come out of the fixed interface of the connector 7 for a long time, the connection strength is higher than the reading of the tension gauge 15.

[0030] Among them, such as Figure 5 As shown, a push plate 34 is fixedly connected to one side of the outer wall of the handle 32. One side of the push plate 34 abuts against the spring 35. The spring 35 is sleeved on the contact rod 36. The contact rod 36 is electrically connected to the controller 38 through the wire 37. The controller 38 is connected to the motor 27 through the control line. When the handle 32 rotates, the push plate 34 contacts the contact point of the contact rod 36 and transmits the electrical signal to the controller 38 through the wire 37. The controller 38 controls the motor 27 to stop rotating, and the tension on the cable 12 no longer increases.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In this invention, connector 7 is placed on placement plate 5, and both sides of connector 7 are limited by limiting plates A8 and B9; one end of cable 12 is connected to a fixed interface of connector 7 to be tested, and the other end is clamped in head clamping assembly 14; placement plate 5 is pushed along slide rail 4, and roller 6 moves within slide rail 4 for adjustment to ensure that cable 12 is in a straight state during testing; motor 27 is turned on, driving rotating shaft 25 and bevel gear B24 to rotate, bevel gear A23 and sprocket B21 follow the rotation, and through hinge 20 and sprocket A19, driving wire roller 17 to rotate slowly, the pull rope 16 wound on wire roller 17 continuously tightens, and the tension acting on cable 12 continuously increases until cable 12 is dislodged from the fixed interface of connector 7, and the maximum tension between connector 7 and cable 12 can be measured. The connection strength is increased; or after the tension increases to the rated value, the handle 33 is pushed to rotate the handle 32. The connecting rod 31 pushes the slider 28 to slide in the groove 29. The brake rubber block 30 contacts the sprocket A19 and applies a certain pressure. When the handle 32 rotates, the push plate 34 contacts the contact point of the contact rod 36 and transmits the electrical signal to the controller 38 through the wire 37. The controller 38 controls the motor 27 to stop rotating and the wire roller 17 to stop rotating. The tension acting on the cable 12 no longer increases. At this time, the reading on the display screen 151 of the tension gauge 15 is the tension strength borne by the cable 12. If the cable 12 does not come out of the fixed interface of the connector 7 for a long time, the connection strength is higher than the rated value of the reading of the tension gauge 15. This is the second method for testing the connection strength between the connector 7 and the cable 12.
