Electrical plug with molded on prongs and detachable wire loops

#This invention relates to an electrical plug with molded on prongs, specifically the electrical wires are mounted on the prongs by detachable wire loops without using screws.

#At present, electrical wires are normally mounted onto contact prongs of an electrical plug by using screws, but when a wire is connected to a contact prong by the use of a screw, the bare end of the wire is first wrapped around the screw and then the screw is tightened, if the wire wrapped around the screw is too short, it may become loose; but if too much wire is used in wrapping, it can lead to difficulty in closing the cover because of limited space in the connecting chamber. The wire may also become loose, if its bare end is wrapped around the screw in the direction opposite to the tightening direction of the screw.

#Although the use of screws for wire and prong connection in some plugs have been eliminated, and replaced by wrapping a wire on a prong, hooking a wire on a prong, or clamping a wire with the cover, they all pose possible hazards of allowing the wire to slip out easily from the prong if the wire were pulled, or creating electrical sparks between the wire and the prong due to lack of tight contact.

#This invention comprises a body (1), a cover (10), and connecting electrical wires (11) tied with loops (13) at their bare ends.

#The body (1) is molded from insulating material such as rubber or plastic, and it contains two metal contact prongs (2). Two separate holes (6) on the body are provided from the top through the connecting chamber (5) for the passage of electrical wires. A divider (4) between the holes continues the separation of the connecting chambers. At the front and rear of the top, two holding edges (7) are provided to ensure an easy plugging and unplugging operation.

#Each of the contact prongs molded onto the body has a finger shaped spring clamp (3) at the center to guarantee perfect contact once a bare wire loop (13) is slipped into position, even if the size of the wire has been varied slightly.
