Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a novel high-voltage wiring harness gland seal ring for new energy vehicles. Background Technology

[0002] With global oil resources becoming increasingly scarce, new energy vehicles have emerged to meet the needs of human travel and cargo transportation. The high-voltage wiring harness in new energy vehicles, serving as the lifeblood of the entire vehicle, carries electrical performance and signal transmission, playing a crucial role. However, during vehicle assembly and subsequent use, abnormal deformation and aging of the sealing structure at the high-voltage wiring harness gland often occur, resulting in poor sealing performance at the harness tail. This leads to water or mud ingress, causing frequent high-voltage drops and rendering the vehicle unable to move. Therefore, sealing the high-voltage gland of new energy vehicles is of paramount importance.

[0003] During the use of existing high-voltage glands, abnormal deformation and aging failure of the sealing structure at the high-voltage wiring harness glands frequently occur during vehicle assembly and later use. This results in poor sealing performance at the tail of the wiring harness, leading to water or mud ingress, frequent high-voltage drops, and vehicle malfunction. Furthermore, the high-voltage gland seal is a closed "O-ring" structure, which cannot be replaced on-site after aging and failure. The only solution is to replace the entire wiring harness, resulting in high after-sales costs and a long processing time.

[0004] Therefore, it is necessary to provide a new type of high-voltage wiring harness gland seal ring for new energy vehicles to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of sealing ring for the high-voltage wiring harness gland of new energy vehicles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel high-voltage wiring harness gland seal ring for new energy vehicles, comprising a cable body, characterized in that it further comprises:

[0007] A sealing ring body is installed on the outside of the cable body to improve the sealing performance of the wire harness. A sealing nut for pressing the sealing ring body is installed on the outside of the cable body. A cable connector body is provided on the outside of the cable body. A sealing nut is fixedly connected to one side of the sealing nut. The inner wall of the sealing nut is threadedly connected to the outer side of the cable connector body.

[0008] Preferably, a mounting sleeve is fixedly connected to one side of the cable connector body, and a locking nut for locking the cable is installed on the inner wall of the mounting sleeve.

[0009] Preferably, the outer side of the cable body is provided with an armored clamping cone for pressing the locking nut, and one end of the armored clamping cone is fixedly connected to a limit block.

[0010] Preferably, the outer side of the cable body is provided with a threaded connector for fixing the wire harness, and the outer side of the threaded connector is threadedly connected to the inner wall of the mounting sleeve.

[0011] Preferably, the inner wall of the threaded connector is provided with a clamping nut for clamping the cable.

[0012] Preferably, one end of the clamping nut is fixedly connected to a limiting sleeve, and the inner wall of the limiting sleeve is engaged with the outer side of the limiting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention installs the cable connector body by connecting the inner wall of the sealing nut to the outer thread of the cable connector body. The sealing ring body is installed inside the sealing nut. The sealing ring body can be used to improve the sealing of the wire harness. The sealing ring body has a non-closed sawtooth structure, which increases the thickness of the sealing ring inside the high-voltage cable gland, allowing for a tighter fit. This greatly improves the sealing, waterproof and dustproof performance of the high-voltage wire harness cable gland. The sealing ring body can be mass-produced and is suitable for various types of high-voltage cable glands, making it convenient for employees to use. Attached Figure Description
