Description

Wire harness connector for vehicle

Technical Field

The utility model relates to a vehicle wire harness connector.

Background

The automobile wire harness is a network main body of an automobile circuit, and the automobile circuit does not exist without the wire harness. The wire harness is a component in which a contact terminal (connector) punched from a copper material is crimped with an electric wire and cable, and then an insulator is molded or a metal case is added to the exterior of the contact terminal, so that a connection circuit is formed by bundling the contact terminal and the cable with the wire harness. The wire harness industry chain comprises wire and cable, connectors, processing equipment, wire harness manufacturing and downstream application industries, the wire harness is widely applied and can be used in the aspects of automobiles, household appliances, computers, communication equipment, various electronic instruments and meters and the like, and the wire harness of the automobile body is connected with the whole automobile body and is generally H-shaped. The wire harness connector can be used as an important part of a wire harness, the wire harnesses of all parts can be connected, but the existing wire harness connector is unstable in connection, and after the wire harness connector is used for a long time, the wire harness connector can be loosened, so that poor contact of the wire harness is caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vehicular pencil connector, its is rational in infrastructure, can make the male joint subassembly more firm with being connected of female plug subassembly, difficult emergence pine takes off the phenomenon.

In order to achieve the purpose, the technical scheme of the utility model is to design a wire harness connector for a vehicle, which comprises a male plug component and a female plug component which are installed in a matching way;

the male plug assembly comprises a male end shell and a male end plug-in connector arranged inside the male end shell, the female plug assembly comprises a female end shell and a female end slot arranged inside the female end shell, the male end plug-in connector is in plug-in fit with the female end slot, the end part, close to the male end shell, of the female end shell extends outwards along the radial direction to form a first convex ring, two guide holes are formed in the first convex ring, the two guide holes are symmetrically arranged relative to the axis of the first convex ring, rubber friction sleeves are fixed in the two guide holes, the end part, close to the female end shell, of the male end shell extends outwards along the radial direction to form a second convex ring, two guide columns are arranged on the second convex ring, the two guide columns are respectively inserted into the rubber friction sleeves of the two guide holes, and the outer walls of the guide columns are tightly matched with the inner walls of the rubber friction sleeves.

Preferably, the outer diameter of the guide column is slightly larger than the inner diameter of the rubber friction sleeve.

Preferably, the end of the guide post away from the second convex ring is in a spherical crown shape.

Preferably, the outer wall of the guide post is provided with knurling patterns.

Preferably, the male end plug connector and the female end slot are both connected with wires.

The utility model has the advantages and the beneficial effects that: the utility model provides a vehicle wire harness connector, its is rational in infrastructure, can make the connection of male joint subassembly and female plug subassembly more firm, is difficult for taking place the pine phenomenon. Through set up the guide post on the second bulge loop to set up the guiding hole on first bulge loop, can play the guide effect when public plug subassembly and female plug subassembly are installed, make the grafting of public end bayonet joint and female end slot more accurate. And when the guide post is inserted into the rubber friction sleeve of the guide hole, the outer diameter of the guide post is slightly larger than the inner diameter of the rubber friction sleeve, so that the rubber friction sleeve is elastically deformed, the inner surface of the rubber friction sleeve presses the guide post, and the friction force between the guide post and the rubber friction sleeve is increased, so that the male connector assembly and the female connector assembly are more firmly connected and are not easy to loosen. In addition, through set up the knurling pattern on the outer wall of guide post, further increased the frictional force between guide post and the rubber friction cover.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model discloses the technical scheme who specifically implements is:

as shown in fig. 1 and 2, a vehicular wire harness connector includes a male plug assembly and a female plug assembly which are fitted together;

the male plug component comprises a male end shell 1 and a male end plug-in connector arranged in the male end shell 1, the female plug assembly comprises a female housing 2 and a female slot disposed within the female housing 2, the male end plug is in plug fit with the female end slot, the end part of the female end shell 2 close to the male end shell 1 extends outwards along the radial direction to form a first convex ring 21, the first convex ring 21 is provided with two guiding holes 211, the two guiding holes 211 are symmetrically arranged relative to the axis of the first convex ring 21, and rubber friction sleeves 3 are fixed in the two guide holes 211, the end part of the male end shell 1 close to the female end shell 2 extends outwards along the radial direction to form a second convex ring 11, two guide posts 111 are arranged on the second convex ring 11, the two guide posts 111 are respectively inserted into the rubber friction sleeves 3 of the two guide holes 211, and the outer walls of the guide posts 111 are tightly matched with the inner walls of the rubber friction sleeves 3.

The outer diameter of the guide post 111 is slightly larger than the inner diameter of the rubber friction sleeve 3.

The end of the guide post 111 remote from the second collar 11 is in the shape of a spherical cap.

The outer wall of the guide post 111 is provided with a knurling pattern.

The male end plug connector and the female end slot are both connected with a lead 4.

The utility model has the advantages and the beneficial effects that: the utility model provides a vehicle wire harness connector, its is rational in infrastructure, can make the connection of male joint subassembly and female plug subassembly more firm, is difficult for taking place the pine phenomenon. Through set up guide post 111 on second bulge loop 11 to set up guiding hole 211 on first bulge loop 21, can play the guide effect when public plug subassembly and female plug subassembly are installed, make the grafting of public end plug and female end slot more accurate. Moreover, when the guide post 111 is inserted into the rubber friction sleeve 3 of the guide hole 211, since the outer diameter of the guide post 111 is slightly larger than the inner diameter of the rubber friction sleeve 3, the rubber friction sleeve 3 will elastically deform, and the inner surface of the rubber friction sleeve 3 will press the guide post 111, thereby increasing the friction force between the guide post 111 and the rubber friction sleeve 3, so that the connection between the male connector assembly and the female connector assembly is firmer and is not easy to loosen. In addition, the outer wall of the guide post 111 is provided with knurling patterns, so that the friction force between the guide post 111 and the rubber friction sleeve 3 is further increased.
