Description

Technical Field

[0001] The utility model relates to the field of automotive connection lines, and particularly to a waterproof and wear-resistant automotive connection line. Background Art

[0002] An automotive connection line is a connection line between electrical components in an automobile, generally composed of an interface and a cable. The interfaces at both ends are snap-fitted and docked to form a connection. During installation, the cable is fixed through structures such as buckles.

[0003] Patent No. CN220691750U discloses a waterproof and wear-resistant automotive connection line, which relates to the technical field of automotive connection lines. The waterproof and wear-resistant automotive connection line includes a conductive cable core, a protection component, and a high-elastic rubber ball. An insulating sheath is fixedly installed on the outer wall of the conductive cable core. The protection component is arranged on the outer wall of the conductive cable core. Connection sockets A and B are respectively fixedly installed at both ends of the conductive cable core, the protection component, and the insulating sheath. The high-elastic rubber ball is arranged between the conductive cable core and the protection component. The waterproof and wear-resistant automotive connection line has a certain anti-tensile effect, avoiding the phenomenon that the connection line is easily damaged due to subsequent stretching, improving the reliability of use, and also having good anti-corrosion, waterproof, and wear-resistant effects, reducing the situations of corrosion damage, water penetration, and easy wear of the connection line. When the connection line is accidentally burned to a certain extent, it can expand and perform a flame-retardant treatment, reducing the situation of electric leakage easily occurring when the connection line is burned out. However, most of the interfaces of the connection line are snap-fit structures, and the protection performance of the interfaces is poor. When colliding during shaking, it is easy to cause damage to the interfaces, and the sealing performance at the interfaces of the connection line is poor, resulting in poor waterproof effect.

[0004] Therefore, aiming at the problems that most of the interfaces of the above connection line are snap-fit structures and the protection performance of the interfaces is poor, a waterproof and wear-resistant automotive connection line can be designed to increase the protection of the interface connection and improve the waterproof effect of the connection. Content of the Utility Model

[0005] In order to overcome the problems that most of the interfaces of the existing connection lines are snap-fit structures and the protection performance of the interfaces is poor.

The left and right ends of the cable are respectively fixedly connected to the left connection socket and the right connection socket. An insertion interface is opened on the surface of the end of the left connection socket away from the cable. A plug block is arranged at the end of the right connection socket away from the cable. A sealing sleeve is arranged on the outside of the right connection socket. A positioning ring is fixedly installed on the side of the surface of the left connection socket.

[0007] The cable is composed of a core, an inner protective layer, and an outer protective layer. A metal protection net is arranged between the inner protective layer and the outer protective layer.

[0008] Preferably, the insertion interface and the insertion block are sleeved, a docking terminal is arranged inside the insertion interface, a docking groove is formed on the surface of the insertion block, and the docking terminals and the docking grooves correspond one by one, which facilitates the docking installation of the connecting wire.

[0009] As a preference, one end of the sealing sleeve is threadedly connected to the outer surface of the left connection socket, and through holes are formed on the surface of the other end of the sealing sleeve, and the sealing sleeve forms a protection for the connection part.

[0010] As a preference, the inner diameter of the through hole is smaller than the outer diameter of the right connection socket, and a sealing gasket is arranged on the side of the inner side of the sealing sleeve at the edge of the through hole, and the sealing sleeve and the right connection socket are in fit, which facilitates sealing.

[0011] As a preference, the outer diameter of the sealing sleeve is adapted to the outer diameter of the positioning ring, and the same sealing gasket is arranged on the surface of the positioning ring, which ensures the sealing performance of the sealing sleeve.

[0012] As a preference, the outer protective layer is made of thermoplastic phenolic resin, and a nano-coating is arranged on the surface of the outer protective layer, which ensures the waterproof and wear-resistant effects of the outer protective layer.

[0013] As a preference, the metal protection net is designed in a grid structure, and the metal protection net and the inner protective layer are coated and connected, which increases the structural strength of the protective layer and avoids the damage of the protective layer.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the waterproof and wear-resistant automotive connecting wire, after the left connection socket and the right connection socket are docked, the insertion block enters the insertion interface, and the sealing sleeve is threadedly installed on the outer side of the left connection socket to realize the protection of the connection part. Both sides of the sealing sleeve are sealed by the sealing gaskets, which ensures the waterproof effect of the connection part, avoids damage to the socket during collision, ensures the connection stability of the automotive connecting wire, and improves the practicability.

[0016] 2. For the waterproof and wear-resistant automotive connecting wire, a double-layer waterproof protection is formed by using the inner protective layer and the outer protective layer, and the metal protection net is added to improve the structural strength of the protective layer, and the nano-coating increases the wear-resistant performance of the cable to prevent the damage of the protective layer.
