Description

Heavy-duty connector grounding piece and locking bolt

Technical Field

Background

In industrial production and connection applications of various electrical devices, a heavy-duty connector plays a crucial role, and the stable connection of the grounding piece is essential for ensuring the safe operation of the device. Conventional heavy-duty connector grounding plates typically employ a grounding plate body coupled with a locking bolt and nut (e.g., application number). However, in the actual use process, due to factors such as vibration, temperature change, mechanical stress and the like generated during the running of the equipment, a loosening phenomenon is very easy to occur between the locking bolt and the nut. Once loose, the connection stability of the grounding piece is affected, so that poor grounding of electrical equipment is possibly caused, potential safety hazards such as electric leakage and short circuit are caused, equipment can be damaged even when serious, and normal production is affected. The existing solution is poor in effect, complex in operation and high in cost. Therefore, a new technical solution is needed to solve the loosening problem between the locking bolt and the nut, so as to improve the connection reliability and stability of the grounding plate of the heavy-duty connector.
