[0002] Electronic scales are widely used in factories, mines, ports, warehouses, docks and other industries to weigh and measure materials. After the weighed items are driven or hoisted onto the electronic scale and stop, the weight of the items acts on the weighing sensor through the electronic scale body and mechanical connectors. The elastic body of the weighing sensor is deformed by force and outputs a signal proportional to the weight value. The junction box aggregates the electrical signals of each sensor and sends them to the weighing display instrument for processing, and displays the weight value on the display window. During the use of electronic scales, in order to prevent personal injury caused by insulation damage of electrical equipment, a grounding device is required for grounding protection, limiting the voltage of the metal casing to the ground within a safe voltage, and grounding the exposed and accessible conductor part of the electrical equipment to improve safety.
