Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harnesses with convenient replacement of connection interfaces, and specifically relates to an automotive wire harness with a convenient replacement of connection interfaces. Background Technique

[0002] The automotive wire harness is the network main body of the automotive circuit. Without the wire harness, there would be no automotive circuit. A wire harness refers to a component formed by crimping contact terminals (connectors) made of copper material with wires and cables, and then molding an insulator outside or adding a metal shell, etc., and bundling the wire harness to form a connection circuit. Generally, the automotive wire harness fixes the wires by clamping them through an interface. When in use, multiple wire harnesses need to be connected, and the interfaces of the wire harnesses are used for connection.

[0003] At the end of the existing automotive wire harness, a male head and a female head are usually installed. When in use, the male head of one wire harness is docked with the female head of another wire harness. The connection between the male head and the female head and the wire harness is mostly fixed in the male head and the female head through a copper tube. The copper tube and the male and female heads are mostly connected by interference fit. When it is necessary to replace the wire harness, for the accessories produced by different models and different manufacturers, the wiring sequences of the male and female heads of the wire harness are often different. At this time, it is often necessary to replace the male and female heads of the wire harness and the sequence of the wires, which is rather inconvenient. Moreover, the connection method of the male head and the female head of the existing automotive wire harness is usually a snap connection, and this method is prone to looseness, thereby affecting the use of electronic devices on the vehicle. Therefore, there is an urgent need for an automotive wire harness with a convenient replacement of connection interfaces to solve the above problems. Summary of the Utility Model

[0041] In order to facilitate improving the connection stability of the wire harness conductor 5, as shown in the appendix Figures 1 to 7As shown in the figure, the present application adopts the following structure. Through the settings of the female connector connecting plate 105, the threaded hole 107, the male connector connecting plate 306, and the second bolt 307, the automotive wire harness with a convenient replacement connection interface has the effect of improving the connection stability between the female head 1 and the male head 3. During actual use, the ends of the female head 1 and the male head 3 are butted. At this time, the male connector connecting pipe 405 will be inserted into the interior of the female connector connecting pipe 205. As it is tightened, the teeth on the lower surface of the male connector connecting plate 306 are engaged with the upper surface of the female connector connecting plate 105. When the second bolt 307 corresponds to the threaded hole 107, the second bolt 307 can be tightened inside the threaded hole 107. At this time, the female head 1 and the male head 3 can be directly fixed, effectively preventing the phenomenon of joint loosening caused by the vibration during vehicle driving. That is, through the cooperative settings of the female connector connecting plate 105, the threaded hole 107, the male connector connecting plate 306, and the second bolt 307, the female head 1 and the male head 3 can be tightly connected by the second bolt 307 during use, effectively reducing the influence of the vibration during vehicle driving on the joint of the wire harness conductor 5, thereby achieving the purpose of facilitating the improvement of the connection stability of the wire harness conductor 5.
