Description

Technical Field

[0001] This utility model relates to the field of wire harness sheathing technology, and in particular to a pressure-resistant automotive wire harness sheath with an internal support component. Background Technology

[0002] Pressure-resistant automotive wiring harness sleeves are protective materials specifically designed to enhance the pressure resistance of wiring harness systems. Their main functions include: 1) Enhanced protection for wiring harness systems through their special materials and design. In complex vehicle environments, wiring harnesses may be subjected to pressure and compression from various directions. Pressure-resistant sleeves effectively absorb and disperse this pressure, preventing damage. 2) Because automotive wiring harness sleeves need to withstand the effects of vibration, friction, and other external factors over long periods, pressure-resistant sleeves significantly improve the durability and extend the service life of the wiring harness through their superior pressure resistance. 3) Pressure-resistant automotive wiring harness sleeves not only protect the wiring harness from physical damage but also isolate different wiring harnesses, facilitating the management of various wiring harnesses in the vehicle. Simultaneously, they prevent dust, moisture, and other impurities from entering the wiring harness, ensuring its cleanliness and dryness, thus avoiding malfunctions caused by moisture or contamination. 4) Pressure-resistant sleeves ensure that the wiring harness will not deform or break under pressure, thereby preventing vehicle safety issues caused by wiring harness failure. This is crucial for improving the overall safety and reliability of vehicles.

[0003] Traditional pressure-resistant automotive wiring harness sleeves have several shortcomings. First, they lack internal support components, requiring further enhancement of the overall pressure resistance. Second, when multiple automotive wiring harnesses are run through them, they do not help organize the wiring harness layout, easily leading to a messy and congested layout, which affects the safe operation of the circuit. Therefore, traditional pressure-resistant automotive wiring harness sleeves need to be optimized and improved. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a pressure-resistant automotive wiring harness sheath with an internal support component.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A pressure-resistant automotive wiring harness sheath with an inner support assembly includes at least one corrugated tube sheath body, inner support joints disposed at both ends of the corrugated tube sheath body, and an inner support spring disposed between two adjacent inner support joints. The spring body of the inner support spring is distributed along the corrugated groove inside the corrugated tube sheath body. The inner support joints and the inner support spring together constitute the inner support assembly.

[0007] The inner support connector consists of a connector seat, a wire threading reel, and a locking screw. The wire threading reel consists of a reel body and symmetrical lugs on both sides. The reel body has wire harness through holes evenly distributed on it. The outer side of the lugs has a fastening screw hole that mates with the locking screw. The connector seat includes a cylindrical seat body. The cylindrical seat body has an annular groove and symmetrical circular grooves on both sides. The circular grooves have symmetrical heat dissipation lugs on both sides. The outer side of the cylindrical seat body has a stepped through hole that mates with the locking screw.

[0008] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with internal support components, the outer diameter of the annular groove matches the outer diameter of the column where the lug is located, the thickness of the annular groove is equal to the thickness of the lug, and the thickness of the lug is less than the thickness of the disc.

[0009] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with internal support components, the diameter of the disc body matches the diameter of the circular groove, and the thickness of the disc body is equal to the thickness of the cylindrical base body.

[0010] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with internal support components, the shape of the heat dissipation ear groove matches the shape of the lug, and the axis of the stepped through hole is perpendicular to the line connecting the two heat dissipation ear grooves.

[0011] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with internal support components, the locking screw can be screwed into the fastening screw hole of the lug through the stepped through hole, and the internal hexagonal end of the locking screw can be hidden in the stepped through hole.

[0012] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with internal support components, the corrugated sheath body is made of plastic material.

[0013] Furthermore, in the aforementioned pressure-resistant automotive wiring harness sheath with an inner support assembly, the inner support spring is made of stainless steel.

[0015] The beneficial effects of this utility model are:

[0016] This utility model has a reasonable structural design. It utilizes an internal support connector and an internal support spring to jointly form an internal support assembly. The internal support spring can improve the compressive strength of the corrugated tube sheath body. The internal support connector consists of a connector seat, a wire threading reel, and a locking screw. The lug of the wire threading reel is inserted into the annular rotating groove through the heat dissipation ear groove and rotated 90 degrees. The locking screw can lock the position of the wire threading reel and the connector seat. The wire threading reel can organize the layout of multiple automotive wiring harnesses and avoid the wiring harnesses from becoming messy and crowded. After the lug rotates and is offset, the heat dissipation ear groove is connected to the inner cavity of the corrugated tube sheath body, which is conducive to heat dissipation. With the help of an external ventilation system, the heat dissipation effect can be further improved, ensuring the safe operation of the circuit.

[0033] In this embodiment, the inner support joint 2 is composed of a joint seat 21, a wire threading reel 22, and a locking screw 23.

[0034] In this embodiment, the threading reel 22 is composed of a reel body 221 and lugs 222 symmetrically arranged on both sides. The reel body 221 is evenly distributed with wire harness through holes 223, the outer side of the lugs 222 is an arc surface, and the outer side of the lugs 222 is provided with a fastening screw hole 224 that cooperates with the locking screw 23.

[0035] In this embodiment, the connector seat 21 includes a cylindrical seat body 211. The cylindrical seat body 211 has an annular rotating groove 212 and a circular through groove 213 symmetrically located on both sides thereon. The circular through groove 213 has heat dissipation ear grooves 214 symmetrically located on both sides thereon. The outer side of the cylindrical seat body 211 has a stepped through hole 215 that cooperates with the locking screw 23.

[0036] In this embodiment, the outer diameter of the annular groove 212 matches the outer diameter of the column where the lug 222 is located. The thickness of the annular groove 212 is equal to the thickness of the lug 222, and the thickness of the lug 222 is less than the thickness of the disc 221.

[0037] In this embodiment, the diameter of the disc 221 matches the diameter of the through groove 213, and the thickness of the disc 221 is equal to the thickness of the cylindrical base 211.

[0038] In this embodiment, the shape of the heat dissipation groove 214 matches the shape of the lug 222, and the axis of the stepped through hole 215 is perpendicular to the line connecting the two heat dissipation grooves 214.
