Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a corrosion-resistant wiring harness terminal. Background Art

[0002] Wiring terminals are plugs or connectors used to connect wires to devices. They typically feature a fixed connection method to ensure stable and reliable connections. Common wiring terminals include pins, sockets, and plugs. They are used in a variety of applications, including automobiles, home appliances, and electronic devices.

[0003] After searching, the announcement number is CN214847839U, which discloses a corrosion-resistant wiring harness, including a wiring harness body detachably connected to a terminal body, the wiring harness body including a hollow tube body, an expansion sleeve provided in the tube body, a clamping cavity formed between the outer wall of the expansion sleeve and the inner wall of the tube body, and a screw that drives the expansion sleeve to undergo elastic deformation is connected to the inner thread of the expansion sleeve. When the terminal body is damaged and needs to be replaced, it is only necessary to rotate the screw to make the expansion sleeve cancel the interference state with the wiring harness body, and then pull the wiring harness body out of the clamping cavity. It is convenient and quick. The polytetrafluoroethylene contained in the corrosion-resistant layer has high chemical stability and can withstand almost all commonly used highly corrosive and hydrogen-oxidizing chemicals. It also has the characteristics of high temperature resistance, which greatly improves the corrosion resistance of the wiring harness body and extends the service life of the wiring harness body.

[0004] However, although the existing wiring harness terminals can be made to have good corrosion resistance through electroplating, when the wiring harness terminals are fixedly connected to the wires of the wiring harness, the existing wiring harness terminals are often fixed to the wires of the wiring harness by squeezing and bending their fins through tools or equipment. In this way, when the wires are loose or detached between the wiring harness terminals and the wiring harness, the wiring harness terminals need to be cut off from the wiring harness. The bent wiring harness terminals are easy to reuse, resulting in a situation where they cannot be reused. There is also inconvenience when manually installing and removing the wiring harness terminals and the wiring harness.

[0005] Therefore, it is necessary to provide a corrosion-resistant wiring harness terminal to solve the above problems.

[0033] Specifically, the wires of the wiring harness are passed through the bottom of the mounting cavity 7 and placed in the cavity on one side of the mounting plate 8 , bent along the mounting groove 9 and then passed through the cavity on the other side of the mounting plate 8 , so that the wires are stuck in the mounting groove 9 .
