Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing, in particular to an anti-loosening wire harness terminal. Background Art

[0002] A wiring harness is a component used to connect and transmit power and signals in electrical systems such as automobiles. It consists of wires, connectors, insulation materials, and fixings. Wire harness terminals are accessories used to connect wires of different colors and functions, connecting them to ensure smooth current transmission within the circuit. When wire harness terminals are left connected for extended periods, their internal components inevitably age and loosen, resulting in a less secure connection between the two terminals and an inability to ensure stable current transmission. When subjected to external forces such as drag or impact, the wire harness terminals can easily become damaged or disconnected, interrupting the flow of current. To address this, we propose a loose-proof wire harness terminal. Utility Model Content

[0003] The purpose of the utility model is to provide a loose-proof wiring harness terminal to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides a loose-proof wiring harness terminal, including a current output bin, which includes a shell, and a fixed component is symmetrically arranged inside the shell. The fixed component includes a push plate, which is slidably arranged inside the shell, and a slider is fixedly arranged on one side of the push plate. A No. 1 card block is rotatably arranged on the upper and lower sides of the slider, and a No. 2 card block is slidably arranged on one side of the slider. A telescopic rod is fixed between the No. 2 card block and the slider, and the telescopic rod is arranged inside the slider. A push rod is fixedly arranged on one side of the telescopic rod, and a pressure spring is fixedly arranged on the end of the push rod away from the telescopic rod, and the end of the pressure spring away from the push rod is fixedly connected to the slider.

[0005] As a further improvement of the present technical solution, a torsion spring is fixedly arranged between the two No. 1 blocks and the slider, a small hole is opened on one side of the shell to facilitate the passage of the slider, a screw rod is inserted through the middle of the push plate, and one end of the screw rod is fixedly arranged on the inner wall of the shell.

When dragged or hit by external force, the pressure spring extends outward and pushes the push rod into the telescopic rod. At the same time, the telescopic rod pushes the No. 2 clamping block into the fixed block to further stabilize the shell and the outer shell. When the device is subjected to external force, it can automatically reinforce the connection between the shell and the outer shell, preventing the device from being disconnected when it is affected by external force. At the same time, it avoids the loosening of the connection between the two wiring harness terminals due to aging of internal parts of the device, thereby improving the stability of the device.
