Abstract
The utility model relates to a wire junction box for electricity wires out of a family ammeter. The wire junction box comprises a box and a power leakage protection. The box contains a mounting plate therein. The power leakage protector is arranged on the mounting plate. A wire inputting low-voltage terminal row and a wire outputting low-voltage terminal row are spaced at interval in horizontal directions under the mounting plate. Both the two rows are provided with flexible metal fixing buckles. At the bottom end of the box are provided an inlet wire hole and an outlet wire hole. The arrangement of the mounting plate enables the power leakage protector to be mounted thereon and aligns the rows; in this way, the power leakage protector does not come off and is, therefore, free of being damaged by external environment. The wire inputting low-voltage terminal row and the wire outputting low-voltage terminal row ensure the superiority of the insulating performances of the contacts, thus staying clear of short circuits and burning damage. For the superiority of insulating performances and the good safety performance, the wire junction box provides more safety assurance to users.
