ABSTRACT:
A connector for electrical cords and cables includes a tubular body, a plastic engaging sleeve, a connecting sleeve and a connecting plug. The plastic engaging sleeve has a sleeve head; a circular groove behind to the sleeve head; a circular projection behind to the circular groove; a circular neck portion behind the circular projection; and a round tapered portion behind the circular neck portion. The circular projection is configured to fit snugly into the circular groove of the tubular body. The round tapered portion serves to provide a compressing space in the manufacturing process. In the manufacturing process, the round tapered portion will be compressed, so that it will be flattened to have like a round cylinder.
