Description

Technical Field

[0001] This utility model relates to the field of sealing sleeve technology, specifically a sealing sleeve for automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are an important component of automobiles. They distribute electrical energy from the battery or generator to various electrical devices in the vehicle and are responsible for transmitting electrical signals to ensure accurate information exchange between the vehicle's sensors, actuators, and control units. A sealing sleeve is a component used to protect automotive wiring harnesses. It is usually made of rubber compound and seals the wiring harness to effectively prevent the intrusion of external impurities such as dust and moisture.

[0003] Existing sealing sleeves rely solely on their own elasticity to adhere to the wire harness for sealing. However, after long-term use, they are prone to aging, leading to a decrease in elasticity and an inability to adhere effectively. This results in gaps between the sealing sleeve and the wire harness, causing sealing failure. Utility Model Content

[0004] The purpose of this invention is to provide a sealing sleeve for automotive wiring harnesses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing sleeve for automotive wiring harnesses, comprising a sealing sleeve body, wherein a first through hole, a second through hole, and a third through hole are provided through the sealing sleeve body, and the inner sidewalls of the first through hole, the second through hole, and the third through hole are respectively provided with two first protrusions, two second protrusions, and three third protrusions, respectively, and the interior of the sealing sleeve body is respectively provided with a second annular spring corresponding to the second protrusion, a third annular spring corresponding to the third protrusion, and a first annular spring corresponding to the first protrusion, wherein the first protrusion, the second protrusion, and the third protrusion are not on the same horizontal plane.

[0006] As a preferred embodiment of this utility model, the second protrusion, the first protrusion, the third annular spring, and the sealing sleeve body are integrally formed.

[0007] As a preferred embodiment of this utility model, the first perforation, the second perforation and the third perforation are triangularly distributed on the sealing sleeve body.

[0008] As a preferred embodiment of this utility model, the sealing sleeve body is made of rubber.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the first ring spring, the second ring spring and the third ring spring provided by this utility model can make the first protrusion, the second protrusion and the third protrusion adhere tightly to the surface of the wire harness under their own elasticity and the combined pressure of the spring, so as to achieve a good sealing effect. Even if aging occurs after long-term use, it can still adhere tightly to the wire harness under the action of the spring, ensuring the reliability of the seal. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 7This utility model provides a technical solution: a sealing sleeve for automotive wiring harnesses, comprising a sealing sleeve body 1, with a first through hole 2, a second through hole 3, and a third through hole 4. The inner walls of the first through hole 2, the second through hole 3, and the third through hole 4 are respectively provided with two first protrusions 7, two second protrusions 5, and a third protrusion 6. The first protrusions 7, the second protrusions 5, and the third protrusion 6 allow the sealing sleeve body 1 to fit the wiring harness more closely. Inside the sealing sleeve body 1 are respectively provided a second annular spring 9 corresponding to the second protrusion 5, a third annular spring 10 corresponding to the third protrusion 6, and a first annular spring 8 corresponding to the first protrusion 7. The first annular spring 8, the second annular spring 9, and... The third annular spring 10 is located on the outside of the first protrusion 7, the second protrusion 5, and the third protrusion 6, respectively. The first annular spring 8, the second annular spring 9, and the third annular spring 10 are used to apply pressure to the first protrusion 7, the second protrusion 5, and the third protrusion 6, respectively, so that the first protrusion 7, the second protrusion 5, and the third protrusion 6 are tightly attached to the outside of the wire harness to improve the sealing effect. Even if aging occurs after long-term use, they can still tightly attach to the wire harness to ensure the reliability of the seal. The first protrusion 7, the second protrusion 5, and the third protrusion 6 are not on the same horizontal plane. Being on different horizontal planes makes the pressure distribution more uniform, avoids pressure concentration, and reduces the seal aging caused by local fatigue after long-term use.

[0020] Among them, the second protrusion 5, the first protrusion 7, the third annular spring 10 and the sealing sleeve body 1 are integrally molded structures. The integrally molded structure not only ensures a more firm and tight connection without gaps, but also facilitates production.

[0021] Among them, the first perforation 2, the second perforation 3 and the third perforation 4 are triangularly distributed on the sealing sleeve body 1. The triangular distribution has a high space utilization rate, which allows the first perforation 2, the second perforation 3 and the third perforation 4 to be evenly distributed on the sealing sleeve body 1, ensuring sufficient spacing between wire harnesses, making the sealing sleeve body 1 around each wire harness more evenly stressed, and ensuring a good sealing effect.

[0022] The sealing sleeve body 1 is made of rubber, which has excellent elasticity and can fit tightly against the surface of the wire harness, thus achieving a good sealing effect.

[0023] Specifically, in use, multiple wire harnesses are passed through the first through hole 2, the second through hole 3, and the third through hole 4 respectively. Under the action of their own elasticity, the first protrusion 7, the second protrusion 5, and the third protrusion 6, as well as the combined action of the first annular spring 8, the second annular spring 9, and the third annular spring 10, they adhere tightly to the surface of the wire harness, thereby achieving a good sealing effect.
