Description

Technical Field

[0001] This utility model relates to the field of nut terminal technology, and in particular to a self-locking nut terminal. Background Technology

[0002] The vibrations generated during equipment operation will subject the mating surfaces of the nut and bolt to repeated pulling, squeezing, and torsion, resulting in increased thread clearance, reduced frictional resistance, and ultimately causing the nut to loosen due to self-rotation.

[0003] Most self-locking mechanisms employ an integrated design, requiring specialized tools to separate the nut from the terminal body during disassembly. This makes the replacement of external wiring harnesses cumbersome, extending equipment downtime for maintenance and potentially damaging the terminal structure during disassembly, necessitating a complete replacement of the terminal assembly and significantly increasing maintenance costs. While some terminals support wiring harness disassembly, the self-locking system must be completely disengaged, requiring readjustment of the anti-loosening structure during reassembly, thus hindering rapid switching. Utility Model Content

[0011] According to the present invention, a self-locking nut terminal is provided on the nut, wherein the nut is provided with a first square hole.

[0012] Beneficial effects: 1. By adding a pin and matching the first square hole, after the nut is threaded, the pin is inserted into the first square hole of the nut. When the terminal vibrates, the pin acts as a stop, preventing the nut from rotating and loosening, thus improving self-locking performance.

[0013] 2. The pin is moved back and forth by a spring and a pull rope, which can quickly separate the self-locking system from the nut, making the device reusable and allowing for quick replacement of the external wiring harness. Attached Figure Description
