Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to an internal positioning wire harness protection structure. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit and the carrier of the automotive circuit. The automotive wiring harness is the bridge and link for the operation of the vehicle's electrical components and the nervous system for the vehicle's power and signal transmission distribution. The wiring harness needs a protective structure to bundle and protect it to prevent it from falling off due to movement. For example, patent document CN 220096299U discloses a wiring harness protection structure for new energy vehicles, which protects the wiring harness through a wiring harness sleeve and an arc frame.

[0003] However, in the wiring harness protection structure disclosed in the patent document, while the wiring harness tube sheath provides protection for the wires, it cannot separate different transmission wires. Various power and signal wires are transmitted inside the wiring harness tube sheath. The various wires are entangled with each other, and different signals interfere with each other, affecting signal transmission. Moreover, when multiple wires are running at the same time, heat is generated at the gathering point of the harness and is not easy to dissipate. In addition, it is not easy to quickly locate the corresponding wires during later maintenance and inspection, resulting in low maintenance efficiency. Therefore, it is urgently necessary to improve the existing wiring harness outer protection structure. Utility Model Content

[0007] Through the multiple conical wire clips arranged at intervals on the wire holder, wires of different signal transmission types can be fixed separately. Multiple wire holders arranged at intervals along the length of the wire harness can enhance the reliability of the wire harness fixation. Moreover, the wires are arranged at intervals to prevent entanglement, which can reduce interference during signal transmission; the wires are arranged at intervals to increase the heat dissipation space, which is conducive to rapid heat dissipation and reduce heat accumulation; the wires are fixed separately, which is conducive to quickly locating the faulty wires and electrical components during maintenance, thereby improving maintenance efficiency.

[0008] In one embodiment, the connector is two long flexible strips, which are spaced apart along the inner diameter direction of the outer sheath of the corrugated tube. The wire clamp seat is a circular plate, and the outer diameter is equal to the inner diameter of the outer sheath of the corrugated tube, and is vertically penetrated on the connector. The conical wire clamps are evenly distributed on the wire clamp seat in an annular manner, and the installation directions are consistent. Specifically, the wire clamp seat has a plurality of mounting holes evenly distributed along the annular intervals, and the conical wire clamp is fixed to the wire clamp seat through the mounting holes. And the installation directions of the conical wire clamps on the two adjacent wire clamp seats on the wire fixing frame are consistent.

[0009] In one embodiment, the cutting grooves are evenly distributed along the circumference of the conical wire clamp, with at least three, and specifically four to six, being conducive to increasing the inner diameter adjustment range of the fixed end of the conical wire clamp to meet the fixing requirements of a wider range of wire diameters.

[0010] In one embodiment, the distance between the bottom of the cutting groove and the wire clamp seat is not less than 5 mm, and can be 5 mm-10 mm, to prevent the wire clamp claw from interfering with the wire clamp seat and limit the angle range of the wire clamp claw opening outward.

[0011] In one embodiment,

[0012] The connector is provided with a plurality of adjustment slots along its length direction for easy bending, and the opening directions of adjacent adjustment slots are arranged in a staggered manner. This is conducive to the bending of the wire rack, especially when the wiring path is long and curved, it is convenient to adjust the bending angle of the wire rack. In one embodiment, a wear-resistant layer is provided inside the outer sheath of the corrugated tube, and the wear-resistant layer is preferably made of steel wire fiber. This is conducive to protecting the wire harness, reducing the wear of the wire harness, and improving the tensile strength of the wire harness.

[0013] The beneficial effects of the utility model are:

[0014] 1) Multiple conical wire clips are arranged at intervals on the wire holder to fix wires of different signal transmission types separately. This can reduce interference during signal transmission and improve heat dissipation performance and maintenance efficiency.

[0015] 2) By setting multiple wire holders at intervals along the length of the wire harness, the reliability of the wire harness fixation is enhanced to prevent the wire harness from falling off due to vibration or movement, causing power outage or leakage in the line.

[0024] Through the multiple conical wire clips 3 arranged at intervals on the wire fixing seat, wires of different signal transmission types can be fixed respectively, and the multiple wire fixing seats arranged at intervals along the length direction of the wire harness can enhance the reliability of the wire harness fixation. Moreover, the wires are arranged at intervals to prevent entanglement, which can reduce interference during signal transmission; the wires are arranged at intervals to increase the heat dissipation space, which is conducive to rapid heat dissipation and reduce heat accumulation; the wires are fixed separately, which is conducive to quickly locating the faulty wires and electrical components during maintenance, thereby improving maintenance efficiency.

[0025] As shown in Figure 2, in one embodiment, the connector 21 is two long flexible strips, which are spaced apart along the inner diameter direction of the outer sheath 1 of the corrugated pipe. The wire clamp seat 22 is a circular plate, and its outer diameter is equal to the inner diameter of the outer sheath 1 of the corrugated pipe, and is vertically penetrated on the connector 21. The conical wire clamps 3 are evenly distributed in an annular manner on the wire clamp seat 22, and the installation direction is consistent. The side of the conical wire clamp with the wire claw is located on the same side of the wire clamp seat.
