Abstract: An injection mold for molding an electrical connector assembly which includes a plurality of terminals, a clamping component located above the plurality of the terminals, and a base body fastened to the plurality of the terminals and the clamping component. The injection mold includes a lower mold and an upper mold. The lower mold has a plurality of lower terminal grooves. Lower portions of the plurality of the terminals are placed in the plurality of the lower terminal grooves. The clamping component is placed on the lower mold. The upper mold is engaged with and mounted on the lower mold. A molding cavity is formed between the upper mold and the lower mold. The upper mold has a plurality of upper terminal grooves. Upper portions of the plurality of the terminals are placed in the plurality of the upper terminal grooves.

Abstract: A method of manufacturing an electrical connector includes specific steps described hereinafter. Stamp a plurality of terminals together with a plurality of clamping portions and a clamping element having a material belt. Insert and fix the plurality of the terminals together with the plurality of the clamping portions to a material carrier, and place the material belt above the material carrier. Electroplate the plurality of the terminals and the clamping element. Mold an insulating housing to the plurality of the terminals and the clamping element. Separate the material carrier, the plurality of the clamping portions and the material belt from the plurality of the terminals and the clamping element respectively, thereby completing manufacturing the electrical connector which has the insulating housing, the plurality of the terminals and the clamping element.

Abstract: A key structure includes two key bodies and two elastic pieces. The two key bodies are disposed face to face. Each of the two key bodies has a base portion. Two opposite ends of the base portion extend sideward towards a same direction to form two extending portions spaced from each other. The two extending portions of one of the two key bodies face to the two extending portions of the other key body, respectively. Two opposite ends of each of the two elastic pieces are fastened in the two extending portions of the two key bodies respectively.
