[0018] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A car wiring harness sleeve includes: a housing 1, a rear cover 2, and a waterproof plug 3. The housing 1 has a through stepped channel 11 inside. The rear cover 2 is disposed in the wide part 111 of the stepped channel 11. A wiring harness channel 21 passes through the rear cover 2. The waterproof plug 3 is sleeved on the front end of the housing 1. A guide strip 15 is provided around the front end of the housing 1. Anti-disengagement buckles 12 and 13 are provided on both sides of the guide strip 15 around the housing 1. A guide groove 31 matching the guide strip 15 is provided around the waterproof plug 3. Anti-disengagement rings 12 and 33 are provided on both sides of the guide groove 31 around the waterproof plug 3. Anti-disengagement buckle 12 is matched and snapped into anti-disengagement ring 32. Anti-disengagement buckle 13 is matched and snapped into anti-disengagement ring 33. A wiring harness channel 24 communicating with the wiring harness channel 21 is provided inside the waterproof plug 3.

[0021] like Figures 1-3 As shown, the working principle of this utility model is as follows:

[0022] The rear cover is installed at the wide part of the stepped channel, serving to seal off the wide section and secure the wire harness. The through-channel wire harness inside the rear cover provides a path for the wire harness and also provides initial positioning and protection. The waterproof plug is fitted tightly to the front of the housing and is a key component for achieving waterproof, dustproof, and gas intrusion prevention functions.

[0023] The guide strip circumferentially positioned at the front of the housing matches the guide groove on the waterproof plug. During installation, the guide strip allows for precise insertion along the guide groove, providing accurate guidance and significantly improving installation efficiency and accuracy. The anti-disengagement clips one and two on either side of the guide strip on the housing interlock with the corresponding anti-disengagement rings one and two on the waterproof plug, forming a robust anti-disengagement structure. Even during vehicle operation, if the wiring harness sheath is subjected to severe vibration or external pulling, the waterproof plug remains firmly fixed to the housing and will not easily detach, ensuring the continuous sealing and protective performance of the entire sheath. The wiring harness channel two inside the waterproof plug, which runs through the wiring harness channel one, allows the wiring harness to pass smoothly through the waterproof plug. Furthermore, the material and structural design of the waterproof plug effectively prevent water, dust, and gas from intruding through the gap between the wiring harness and the channel, providing comprehensive protection for the wiring harness from external environmental influences.

[0024] The sheath assembly, consisting of the housing, rear cover, and waterproof plug, is made of insulating material. It effectively isolates the high-voltage wiring harness from the electrical connections of other vehicle components, preventing short circuits and leakage, ensuring the safety of the vehicle's electrical system, and guaranteeing the safe and stable operation of the vehicle.

[0025] As a further preferred embodiment, the rear cover 2 is provided with annular protruding ribs 22 at intervals on its exterior. These annular protruding ribs on the exterior of the rear cover significantly enhance the stability of the wiring harness protection from multiple directions. Laterally, when the vehicle experiences bumps or swaying that generate side impact forces, the ribs increase friction to prevent lateral displacement of the rear cover, preventing the wiring harness from sliding and rubbing against other components, thus maintaining insulation and current transmission safety. Longitudinally, the forward and backward forces of vehicle start-stop, acceleration, and deceleration can easily cause the wiring harness and rear cover to move. The ribs strengthen the longitudinal connection of the rear cover, preventing the wiring harness from being pulled or twisted, ensuring its physical state and electrical performance stability, and comprehensively improving protection reliability.

[0026] As a further preferred embodiment, the wiring harness channel 21 of the rear cover 2 is provided with annular inner protruding ribs 23 at intervals. These annular inner protruding ribs, located inside the wiring harness channel, primarily serve to better hold and position the wiring harness. When the wiring harness passes through the channel, these ribs tightly conform to the surface of the wiring harness, preventing it from shaking within the channel. Vibrations during vehicle operation can easily cause the wiring harness to shake and rub; the presence of the ribs effectively reduces this, protecting the wiring harness sheath from wear, ensuring stable electrical performance of the wiring harness, and improving the safety and reliability of the wiring harness within the sheath.

[0027] As a further preferred embodiment, the right end face of the rear cover 2 is provided with an arc-shaped guide surface 24, and the inside of the wide portion 111 is provided with annularly spaced support portions 112. The left end face of the support portion 112 is matched and fitted with the arc-shaped guide surface 24. The arc-shaped guide surface on the right end face of the rear cover can guide the rear cover when it is installed into the stepped channel wide portion, making it easier and smoother to install the rear cover into place. The support portion inside the wide portion matches and fits with the arc-shaped guide surface, providing stable support for the rear cover.

[0028] As a further preferred embodiment, the housing 1 is provided with two sets of stepped channels 11. Each set of stepped channels 11 has a rear cover 2 inside its wide portion 111, and both sets of stepped channels 11 are externally secured with waterproof plugs 3. This allows for simultaneous protection of two different wiring harnesses, meeting the needs of complex wiring within automobiles.

[0029] As a further preferred embodiment, the housing 1 is provided with reinforcing ribs 14 located outside the stepped channel 11. The reinforcing ribs enhance the overall structural strength of the housing.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
