Abstract

The invention relates to the field of safety lead wires, and particularly discloses an external safety lead wire device for an electric power meter box, which comprises the electric power meter box, a mounting structure mounted on the electric power meter box, and a wiring terminal required to be connected with the mounting structure, the wiring terminal is of an L-shaped structure, and the wiring terminal is used for mounting a lead wire. The installation structure is used for being connected with equipment parts in the electric power meter box, and the installation structure is arranged on the bottom side of the electric power meter box. The wiring terminal and the wiring buckle which are mutually cohesive are combined in a plug-in contact mode, meanwhile, a locking structure is arranged on the side wall, the wiring terminal is stably inserted into the connector base, horizontal traction and longitudinal swing tension can be resisted, the wiring terminal is tightly inserted into the connector base, a limiting structure of the wiring terminal is triggered to reset through triggering of an internal bimetallic strip, and the wiring terminal is prevented from being damaged. The wiring terminal is driven to be separated from the plane and the side wall where the bimetallic strips on the two sides are located to achieve circuit breaking, and meanwhile troubleshooting can be easily achieved, and maintenance is convenient.

Description

technical field [0001] The invention relates to the field of safety lead wires, and more particularly, to a safety lead wire device for external use of a power meter box. Background technique [0002] Instrument boxes generally include shells, panels, linings, brackets and other components. Widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other industries, mainly play the role of protection components. The instrument box is made of aluminum alloy material as the skeleton, and ABS, MDF, plywood, etc. as the panel. [0003] The existing power meter box is directly connected to the device by passing the lead wire directly through the lower end hole. The terminal will be dragged and other external forces during use, which will make the terminal unstable and cause loosening. Because the terminal surface is small, it is easy to overheat, causing the terminal to be overheated or open fir...
