Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and specifically to a testing fixture for automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a plastic-molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, but when using testing devices, they require clamps to hold them in place. Some existing automotive wiring harness testing clamps require operators to rotate bolts to move the clamping plate, which is laborious and reduces testing efficiency. Furthermore, the clamping process does not allow for positional adjustments, potentially leading to wiring harness misalignment and affecting the accuracy of testing. Utility Model Content

[0003] In view of this, the present invention provides a testing fixture for automotive wiring harnesses, which can not only automatically clamp automotive wiring harnesses, but also limit and adjust the automotive wiring harnesses to avoid skewing during the clamping process, thus ensuring the accuracy of automotive wiring harness testing and improving the testing efficiency of automotive wiring harnesses.

[0004] To solve the above technical problems, this utility model provides a testing fixture for automotive wiring harnesses, including a testing table, a movable component is provided on the surface of the testing table, two clamping seats are symmetrically arranged on the movable component, and clamping limiting components are provided on the clamping seats.

[0005] The clamping and limiting assembly includes an electric push rod mounted on the upper end of the clamping seat. A clamping plate is connected to the telescopic end of the electric push rod. A clamping groove is formed at the bottom of the clamping seat. Fixing blocks are provided on the opposite sides of both clamping seats. A second motor is mounted on the surface of each fixing block. A second threaded rod is fixedly connected to the output shaft of each second motor. A second sliding groove is formed at the upper end of each fixing block. A limiting plate is slidably connected within the second sliding groove. Both limiting plates are threadedly connected to the second threaded rod. During operation, the operator can place both sides of the automotive wiring harness to be inspected onto the clamping groove. The operator can then activate the electric push rod, causing the clamping plate to extend downwards and contact the upper surface of the automotive wiring harness. Through cooperation with the clamping groove, the automotive wiring harness is clamped and fixed. The operator can then activate the second motor, causing the second threaded rod to rotate. Under the action of the thread, the limiting plates on both sides can be moved closer to the automotive wiring harness, limiting and correcting the wiring harness to prevent it from being skewed during clamping.

[0006] The moving component includes a first motor mounted on the side of the testing table. A first threaded rod is fixedly connected to the output shaft of the first motor. Two first sliding grooves are symmetrically opened at the upper end of the testing table. Moving blocks are slidably connected in both first sliding grooves. Both moving blocks are threadedly connected to the first threaded rod. The operator can start the first motor to rotate the first threaded rod. Under the action of the thread, the movement of the moving blocks on both sides can drive the clamping seats to move to both sides at the same time, to stretch the automotive wiring harness and ensure that the automotive wiring harness is stretched flat.

[0007] The clamping seat is located at the top of the moving block.

[0008] Both the first and second threaded rods are bidirectional threaded rods, with opposite thread shapes on both sides, which can realize the relative movement between the moving block and the limiting plate.

[0009] The clamping plates and clamping slots are aligned vertically, and the clamping surfaces of both the clamping plates and clamping slots are arc-shaped, which facilitates full clamping of the automotive wiring harness surface.

[0010] The clamping base has symmetrical moving slots, and each moving slot has a connecting block that is slidably connected to it. The two connecting blocks on the same side are connected to the clamping plate, which ensures the stability of the clamping plate and avoids the clamping plate from tilting during long-term clamping and fixing, thus affecting the clamping effect on the automotive wiring harness.

[0011] In summary, compared with the prior art, the detection clip for automotive wiring harnesses included in this application has the following advantages:

[0012] 1. When this utility model is used, it can not only automatically clamp the automotive wiring harness, but also limit and adjust the automotive wiring harness to avoid skewing during the clamping process, thus ensuring the accuracy of automotive wiring harness testing and improving the testing efficiency of automotive wiring harness.

[0013] 2. When using this utility model, the operator can start the first motor to make the first threaded rod rotate. Under the action of the thread, the movement of the moving blocks on both sides can drive the clamping seat to move to both sides at the same time, so as to stretch the car wiring harness and ensure that the car wiring harness is stretched flat.

[0014] 3. When this utility model is used, the clamping base is symmetrically provided with moving grooves, and connecting blocks are slidably connected in each moving groove. The two connecting blocks on the same side are connected to the clamping plate, which ensures the stability of the movement of the clamping plate and avoids the clamping plate from tilting during long-term clamping and fixing, thus affecting the clamping effect on the automotive wiring harness.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown: This embodiment provides a testing fixture for automotive wiring harnesses, including a testing platform 100. A moving component 200 is provided on the surface of the testing platform 100. Two clamping seats 300 are symmetrically arranged on the moving component 200. A clamping limiting component 400 is provided on the clamping seat 300.

[0021] The clamping and limiting assembly 400 includes an electric push rod 401 disposed on the upper end of the clamping seat 300. A clamping plate 402 is connected to the telescopic end of the electric push rod 401. A clamping groove 403 is provided at the bottom of the clamping seat 300. Fixing blocks 404 are provided on the opposite sides of both clamping seats 300. A second motor 405 is provided on the surface of each of the two fixing blocks 404. A second threaded rod 407 is fixedly connected to the output shaft of each of the second motors 405. A second sliding groove 406 is provided at the upper end of each fixing block 404. A limiting plate 408 is slidably connected within the second sliding groove 406. Both limiting plates 408 are threadedly connected to the second threaded rod 407. During operation, the operator can insert the vehicle to be inspected. The wiring harness is placed on both sides of the clamping slots 403. Then, the operator can activate the electric push rod 401 to extend the clamping plate 402 downwards and contact the upper surface of the wiring harness. The clamping plate 402, in cooperation with the clamping slots 403, clamps and fixes the wiring harness. Afterwards, the operator can activate the second motor 405 to rotate the second threaded rod 407. Under the action of the thread, the limiting plates 408 on both sides can be driven to move closer to the wiring harness to limit and correct the wiring harness, preventing the wiring harness from being in a skewed state during clamping. The clamping plate 402 and the clamping slots 403 correspond vertically, and the clamping surfaces of the clamping plate 402 and the clamping slots 403 are both arc-shaped, which facilitates full clamping of the surface of the wiring harness.

[0022] According to another embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the moving assembly 200 includes a first motor 201 disposed on the side of the testing table 100. A first threaded rod 203 is fixedly connected to the output shaft of the first motor 201. Two first sliding grooves 202 are symmetrically opened at the upper end of the testing table 100. Moving blocks 204 are slidably connected in both first sliding grooves 202. Both moving blocks 204 are threadedly connected to the first threaded rod 203. The operator can start the first motor 201 to rotate the first threaded rod 203. Under the action of the thread, the movement of the moving blocks 204 on both sides can drive the clamping seat 300 to move to both sides simultaneously, thus inspecting the automotive wiring harness. The stretching operation is performed to ensure that the automotive wiring harness is stretched flat. The clamping seat 300 is located at the upper end of the moving block 204. The first threaded rod 203 and the second threaded rod 407 are both bidirectional threaded rods with opposite thread shapes on both sides, which can realize the relative movement between the moving block 204 and the limiting plate 408. The clamping seat 300 is symmetrically provided with moving grooves 501, and each moving groove 501 is slidably connected with a connecting block 502. The two connecting blocks 502 on the same side are connected to the clamping plate 402, which ensures the stability of the movement of the clamping plate 402 and avoids the clamping plate 402 from tilting during long-term clamping and fixing, thus affecting the clamping effect on the automotive wiring harness.

[0023] The method of using this utility model is as follows: During operation, the operator places the two sides of the automotive wiring harness to be inspected onto the clamping grooves 403. Then, the operator activates the electric push rod 401, causing the clamping plate 402 to extend downwards and contact the upper surface of the automotive wiring harness. Through cooperation with the clamping grooves 403, the wiring harness is clamped and fixed. Afterwards, the operator activates the second motor 405, causing the second threaded rod 407 to rotate. Under the action of the thread, the limiting plates 408 on both sides can be moved closer to the automotive wiring harness, limiting and correcting its position to avoid... To prevent the automotive wiring harness from being skewed during clamping, the operator can then activate the first motor 201, causing the first threaded rod 203 to rotate. Under the action of the thread, the movement of the moving blocks 204 on both sides can simultaneously move the clamping seat 300 to both sides, stretching the automotive wiring harness and ensuring that the wiring harness is stretched flat. This utility model can not only automatically clamp the automotive wiring harness, but also limit and adjust the automotive wiring harness to avoid skew during clamping, ensuring the accuracy of automotive wiring harness testing and improving the testing efficiency.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
