Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness connector technology, and in particular to an automotive wiring harness connector. Background Technology

[0002] In the current technology, with the rapid development of the automotive industry, the electronic systems inside automobiles have become increasingly complex. Both new energy vehicles and gasoline-powered vehicles require wiring. Automotive wiring harness connectors, commonly known as plugs, are frequently used electronic components in automotive wiring. Connectors not only allow multiple branch lines to be drawn from the main wiring harness but also serve as fixed terminals. As a crucial component of automotive electronic systems, the performance and quality of wiring harness connectors have a significant impact on the safety and stability of the vehicle. Due to the numerous and complex wiring systems inside vehicles, wires are often connected to other components by bending. However, the wires at these bends lack related fixing and guiding structures, making them susceptible to pulling and dragging. This results in significant tensile force on the wires at the bends, affecting their lifespan and posing a risk of breakage. Currently, the connection between wires and connectors is only achieved through the clamping action of the terminals, making disassembly inconvenient and the connection unstable. Pulling the wires can easily cause them to come loose, affecting the normal installation process.

[0003] Chinese utility model patent application number 202323083608.9 discloses an automotive wiring harness connector, including a housing, a transition shell on one side of the housing, and a fixed shell on the other side of the transition shell. The fixed shell is used to pass through the wire, and the wire passes through the transition shell and is fixed inside the housing. The lower end of the fixed shell is hinged to the transition shell, and a telescopic rod is rotatably provided on the upper end of the fixed shell. The other end of the telescopic rod is connected to a limit block through a first spring. The transition shell has a limit hole that cooperates with the limit block. The housing has a socket with a terminal block inside. The housing has a T-shaped hole, and a T-shaped rod is slidably provided in the T-shaped hole. A second spring is sleeved on the T-shaped rod. The lower end of the T-shaped rod passes through the socket and extends into the wire inlet of the terminal block. The lower end of the T-shaped rod has a locking hole. However, this automotive wiring harness connector has a relatively complex structure. Although it can reduce the risk of terminal breakage, its spring structure results in poor stability in the assembled state, making it prone to loosening and affecting the working effect of the connection end.
