Description

Technical Field

[0001] The utility model relates to the technical field of wire harness terminal processing, in particular to a wire harness terminal pull-off force detection device. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component connecting the circuit with the wiring harness. From the functional point of view, the automotive wiring harness can be divided into two types: power lines that carry power to drive the actuator (actuator) and signal lines that transmit sensor input commands. With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products in automobiles are also increasing, and the automotive wiring harness is becoming more and more complex, and the failure rate of the wiring harness is also increasing accordingly.

[0003] At present, the inspection of wiring harness terminals is generally carried out by manual pulling to ensure that the wiring harness terminals are firmly installed. However, manual inspection is time-consuming, labor-intensive, inefficient, and consumes a large inspection cost. There is also a large error between the inspection result and the actual result. Some existing wiring harness terminal pull-off force detection devices can only detect a single wiring harness terminal at a time, and the detection efficiency is very low. For the inspection of mass-produced wiring harness terminals, the workload is large. For this reason, we propose a wiring harness terminal pull-off force detection device. Utility Model Content

[0024] It should be noted that when the utility model is used, the U-shaped slide 13 is adjusted to the position of the end of the slide groove 23 in the initial state, so that the U-shaped slide 13 is close to the tension display 7. During the test, the connection end of the harness terminal is placed in the slide seat 8, and the harness is located in the harness passage of the slide seat 8. The adjusting knob 10 is turned to clamp the two clamping plates 11 on both sides of the connection end, and the harness end is placed in the arc groove between the two line clamps 15. Then, the rotating disk 17 is turned to make the two line clamps 15 clamp the two sides of the connection end. After the wiring harness is clamped and the six groups of wiring harness terminals to be tested on the operating panel 5 are installed, the adjusting handle 26 is turned to rotate the worm 25, and the threaded rod 19 is rotated through the meshing connection between the worm 25 and the worm wheel 24. The lifting block 20 slides up through the threaded connection between the lifting block 20 and the threaded rod 19, and the U-shaped slide 13 is pushed away from the tension display 7 under the action of the adjusting rod 21 to pull the wiring harness terminal. The tension degree can be observed at all times according to the tension display 7 to detect the pull-off force of the wiring harness terminal.

[0025] The detection mechanism 6 includes a tension display 7, a sliding seat 8, a first bidirectional screw 9, an adjusting knob 10 and a clamping plate 11. The top of the operating panel 5 is equidistantly fixedly connected with the tension display 7, the end of the pull rod of the tension display 7 is fixedly connected with the sliding seat 8, the first bidirectional screw 9 is rotatably connected between the two corresponding inner walls of the sliding seat 8 through a bearing, the two ends of the first bidirectional screw 9 are symmetrically threadedly connected with the clamping plate 11, the clamping plate 11 is slidably connected in the sliding seat 8, a wiring harness opening is opened on the side of the sliding seat 8 away from the tension display 7, and the end of the first bidirectional screw 9 passes through the sliding seat 8 and is fixedly connected with the adjusting knob 10.

[0026] It should be noted that by turning the adjusting knob 10, the distance between the two clamping plates 11 in the sliding seat 8 can be adjusted, so that the connecting head of the wiring harness terminal can be clamped and fixed; when fixing, the adjusting knob 10 is turned to rotate the first bidirectional screw 9, and the two clamping plates 11 are threadedly connected to the two ends of the first bidirectional screw 9, so that the two clamping plates 11 are close to each other at the same time, so that the connecting head of the wiring harness terminal can be clamped and fixed, and the wiring harness is located in the wiring harness passage of the sliding seat 8.

[0027] The top of the operating panel 5 is located outside the tension display 7 and is equidistantly connected to six U-shaped slides 13, and the six U-shaped slides 13 correspond to the positions of the six tension displays 7.

The end of the second bidirectional screw 14 passes through the U-shaped slide 13 and is fixedly connected to a rotating disk 17, and a wire harness groove is opened on the side wall of the line clamp 15.

[0028] It should be noted that the distance between the two line clamps 15 can be adjusted by rotating the rotating disk 17, so that the wiring harness portion of the wiring harness terminal can be clamped and fixed; rotating the rotating disk 17 causes the second bidirectional screw 14 to rotate, and through the threaded connection between the two line clamps 15 and the two ends of the second bidirectional screw 14, the two line clamps 15 are brought close together until the wiring harness is clamped and fixed.

[0030] It should be noted that the setting of the limit rod 12 limits the movement of the clamping plate 11, ensuring the smooth movement of the clamping plate 11, and the setting of the guide rod 18 limits the movement of the line clamping plate 15, ensuring the smooth movement of the line clamping plate 15.

[0031] The line clamp plate 15 is located at one side of the wiring harness connecting port and is fixedly connected with an anti-skid pad 16 .

[0032] It should be noted that the provision of the anti-slip pad 16 can increase the friction with the wire harness, thereby achieving a stable clamping of the wire harness.

The top of the slider 22 passes through the operating panel 5 and is fixedly connected to the U-shaped slide seat 13.

[0034] It should be noted that when the threaded rod 19 rotates, the lifting block 20 slides up through the threaded connection between the lifting block 20 and the threaded rod 19, and the U-shaped slide 13 is pushed away from the tension indicator 7 under the action of the adjusting rod 21 to pull the wiring harness terminal. The tension degree can be observed at all times according to the tension indicator 7 to detect the pull-off force of the wiring harness terminal.

[0036] It should be noted that the coordinated arrangement of the worm 25 and the worm wheel 24 has a good self-locking function, and can better locate the moving position of the U-shaped slide 13 .

[0037] An adjusting handle 26 is rotatably connected to the surface of the fixing plate 3 , and an end of the worm 25 passes through the fixing plate 3 and is fixedly connected to the adjusting handle 26 .

[0038] It should be noted that the worm 25 can be controlled to rotate by rotating the adjustment handle 26 , and the threaded rod 19 can be rotated by the meshing connection between the worm 25 and the worm wheel 24 .
