Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, and more specifically, to an on-board wire harness quality testing device. Background Technology

[0002] The vehicle wiring harness is the main network of the automotive circuit. Without the wiring harness, the automotive circuit would not exist. The wiring harness connects the various electrical components of the car through components such as wires, connectors, protective sleeves and positioning parts, so as to realize the transmission and interaction of information, and at the same time transmit electrical signals to provide power support for various systems.

[0003] In the existing technology, the tensile strength test of wire harnesses and wire harness terminals is mostly carried out by terminal tensile testing machines. However, given the variety of terminals in automotive wire harnesses, and the fact that the clamping mechanism and tensile tester use the same type of clamp, the clamp on one end of the tensile tester often cannot match the terminal due to the different shapes of the terminals, which can easily lead to slippage or loosening. This results in inaccurate test data or the need to replace the clamp of the tensile tester, making the testing process unsmooth. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle wiring harness quality testing device to solve the problem of inaccurate test data caused by insufficient adaptability of the clamp at one end of the tension gauge in the prior art.

[0005] To achieve the above objectives, an on-board wiring harness quality inspection device is provided, comprising an inspection box body and a tensile tester and a clamping mechanism disposed on the top of the inspection box body. The tensile tester includes a fixed base, which is fixed to the inspection box body by multiple screws. A box body is fixedly installed on the top of the fixed base. A base is connected inside the box body on the side near the clamping mechanism. A circular slot is opened at the center of the base, and a rotating platform is rotatably connected inside the circular slot. A sliding groove is provided on the outer side of the rotating platform, which matches a sliding groove opened on the inner wall of the circular slot. Multiple ball bearings are rotatably connected inside the sliding groove. The rotating platform is fixed to a multi-diameter clamping platform by fixing screws.

[0006] As a further improvement to this technical solution, the multi-diameter card holder is provided with multiple slots of different diameters around its perimeter to accommodate wire harness terminals of different diameters, and a data screen and test button are provided on the top of the box.

[0007] As a further improvement to this technical solution, a sliding opening is provided on the top of the detection box body, and the clamping mechanism includes a sliding plate, the bottom of which is slidably connected inside the sliding opening by a fixedly installed slider.

[0008] As a further improvement to this technical solution, a clamp is slidably connected in the slot above the sliding plate. Two sets of clamps are symmetrically distributed axially. A threaded rod is threadedly connected to one side of the clamp, and the threaded rod passes through both clamps. When the threaded rod rotates in a circle, the different threads on the threaded clamps will cause the two clamps to move towards each other or opposite directions, clamping the wire harness to be tested inside.

[0009] As a further improvement to this technical solution, a support frame is provided above the sliding plate near the handle of the threaded rod, and the threaded rod passes through the support frame.

[0010] As a further improvement to this technical solution, a thruster is rotatably connected inside the detection box body on the side away from the threaded rod. When the thruster rotates, it will drive the sliding plate to move axially along the inside of the sliding opening.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This vehicle-mounted wiring harness quality inspection device uses a rotating table with multi-diameter bayonet, which can accommodate terminals of different sizes and shapes without frequent clamp changes. It is suitable for various testing needs, improves testing efficiency, ensures a tight fit between the wiring harness and the terminal, avoids slippage or loosening, and guarantees the accuracy and reliability of test results. The carefully designed bayonet diameter allows the terminal to be fixed directly into the bayonet without the need for secondary adjustment of clamping pressure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 As shown, the purpose of this embodiment is to provide an on-board wiring harness quality testing device, including a testing box body 100, a tensile tester 200 and a clamping mechanism 300 disposed on the top of the testing box body 100. The tensile tester 200 includes a fixing base 201, which is fixed to the testing box body 100 by multiple screws. A box body 202 is fixedly installed on the top of the fixing base 201. A base 203 is connected inside the box body 202 near the clamping mechanism 300. A circular slot is opened at the center of the base 203, and a rotating platform 205 is rotatably connected inside the circular slot. A sliding groove 206 is provided on the outer side of the rotating platform 205. The sliding groove 206 slides against the inner wall of the circular slot. The groove 206 fits, and multiple balls 207 are rotatably connected inside the sliding groove 206. The rotating platform 205 is fixed to the multi-diameter clamping table 204 by fixing screws 208. The multi-diameter clamping table 204 has multiple slots of different diameters around its perimeter to accommodate wire harness terminals of different diameters. The box 202 has a data screen 209 and a test button 210 on its top. By rotating the rotating platform 205 inside the circular groove, the rotating platform 205 and the multiple balls 207 inside the sliding groove 206 that fit the circular groove rotate together, fixing the multi-diameter clamping table 204 to the rotating platform 205 by fixing screws 208, and inserting the wire harness terminal into the appropriate slot of the multi-diameter clamping table 204.

[0024] In addition, to secure the tail of the vehicle wiring harness, a sliding opening 306 is provided on the top of the detection box body 100. The clamping mechanism 300 includes a sliding plate 301. The bottom of the sliding plate 301 is slidably connected inside the sliding opening 306 via a fixedly installed slider. A clamp 302 is slidably connected in a slot above the sliding plate 301. Two sets of clamps 302 are symmetrically distributed axially. A threaded rod 303 is threadedly connected to one side of the clamp 302, and the threaded rod 303 passes through both clamps 302. When the threaded rod 303 rotates circumferentially, the threaded connection... The different threads on the clamps 302 cause the two clamps 302 to move towards each other or opposite each other, clamping the wire harness to be tested inside. A support frame 304 is provided above the sliding plate 301 near the handle of the threaded rod 303, and the threaded rod 303 passes through the support frame 304. When the wire harness terminal is fixed on the multi-diameter chuck 204, the tail of the wire harness is placed in the gap between the two sets of clamps 302. Then, by rotating the threaded rod 303, the two sets of clamps 302 are squeezed towards the center to clamp the wire harness, so that the tail of the wire harness will not slip off.

[0025] Furthermore, to prevent the vehicle wiring harness quality inspection device from loosening, a thruster 305 is rotatably connected inside the inspection box body 100 on the side away from the threaded rod 303. When the thruster 305 rotates, it drives the sliding plate 301 to move axially along the inside of the sliding opening 306. The inside of the thruster 305 is connected to the slider below the sliding plate 301 through gears. When the thruster 305 is rotated, the slider drives the sliding plate 301 to move axially along the sliding opening 306 through the gear engagement, making the entire wiring harness taut and continuing to apply pressure. The tension on the wiring harness is directly reflected on the data screen 209 above the box body 202. In the prior art, the data screen 209 will maintain the display of the highest tension value so that the staff can record it.

[0026] The working principle of this device is as follows: The operator rotates the rotating platform 205 within the circular slot. Multiple balls 207 within the sliding groove 206, which mates with the circular slot, rotate in coordination with the rotating platform 205. This fixes the multi-diameter clamping station 204 to the rotating platform 205 using fixing screws 208. The wire harness terminal is then inserted into the appropriate slot of the multi-diameter clamping station 204. Once the wire harness terminal is fixed to the multi-diameter clamping station 204, the operator places the tail of the wire harness in the gap between the two sets of clamps 302 and rotates the threaded rod 303. As the threaded rod 303 rotates circumferentially, the threaded connection... The different threads on the clamps 302 cause the clamps 302 on both sides to move towards each other or opposite each other, so that the two sets of clamps 302 squeeze and clamp the wire harness towards the center, so that the tail of the wire harness will not slip off. When the pusher 305 is rotated, through the cooperation of gears, the slider will drive the sliding plate 301 to move axially along the sliding opening 306, so that the entire wire harness is in a taut state and pressure is continued to be applied. The tension on the wire harness will be directly reflected on the data screen 209 above the box 202. In the prior art, the data screen 209 will keep the highest tension value displayed so that the staff can record it.
