Description

Technical Field

[0001] The utility model relates to a positioning tool for a pre-installed high-precision positioning harness which is convenient to install and belongs to the technical field of commercial vehicle sensor connection. Background Art

[0002] The pre-installed high-precision positioning wiring harness for commercial vehicle sensor connections is a high-quality electrical connection solution designed specifically for the complex operating environment of commercial vehicles. It uses advanced pre-installation technology to ensure accurate connection between the wiring harness and the sensor, and can maintain stable signal transmission even when the vehicle is in motion, effectively avoiding loose connections or signal distortion caused by factors such as vibration and temperature changes. This wiring harness not only has excellent durability and anti-interference capabilities, and can withstand the challenges of harsh road conditions and complex environments, but also further improves the efficiency and accuracy of signal transmission through optimized layout and material selection, providing commercial vehicles with more accurate and reliable sensor data support, thereby optimizing vehicle control performance and enhancing driving safety and comfort. It is an indispensable and important part of modern commercial vehicle electronic systems.

[0003] The existing pre-installed high-precision positioning harness positioning tooling is not convenient to adjust the support position during use, and the positioning accuracy is difficult to guarantee. If the tooling is not convenient to adjust, the operator may not be able to accurately align the sensor harness during the installation process, resulting in positioning errors and affecting the performance of the vehicle sensor. Secondly, the assembly efficiency is low, and each installation requires more time and effort to ensure the accuracy of positioning, which will undoubtedly reduce the production efficiency of the assembly line. Furthermore, the tooling that is inconvenient to adjust may not be able to adapt to sensor harnesses of different sizes and models, resulting in the need to customize special tooling for each harness, increasing production costs. Finally, if the tooling deviates or wears during use, the inconveniently adjusted design will make maintenance and adjustment difficult, thereby affecting the long-term stability and service life of the tooling.

[0004] Therefore, a positioning tool for pre-installed high-precision positioning wiring harness that is easy to install is proposed. Utility Model Content

[0028] The output end of the servo motor 501 drives the screw 502 to rotate. During the rotation process, the screw 502 drives the adjusting screw sleeve 503 to move horizontally by the action of the thread. The adjusting screw sleeve 503 drives the sliding rod 505 to move horizontally through the connecting rod 504, which can adjust the use orientation of the adjustment base plate 6. The output end of the electric telescopic rod 10 is extended and retracted up and down to drive the adjustment top plate 11 to move up and down, which can adjust the distance between the positioning seat 9 and the limit seat 12, thereby further improving the fixation applicability of the wiring harness.

[0029] Example 2

[0030] In one embodiment, the bottom of the adjusting screw sleeve 503 is fixedly connected to the sliding rod 505, the bottom of the inner wall of the mounting seat 2 is provided with a sliding groove 8, the bottom of the sliding rod 505 is slidably connected to the inner cavity of the sliding groove 8, the top of the mounting seat 2 is provided with a through groove 7, the top of the connecting rod 504 passes through the inner cavity of the through groove 7 and extends to the top of the mounting seat 2, the front surface of the mounting seat 2 is fixedly connected to the cover plate 3 by fastening screws, and the inner surface of the mounting plate 1 is provided with mounting grooves 4.
