Abstract
A power plug is proposed, including a terminal base having at least one conductive terminal and a ground terminal; an electric wire having core wires connected to the conductive terminal and ground terminal, respectively; a cover integrally connected to the terminal base; and a ground mechanism for grounding isolated metal parts (such as screws). The ground mechanism can prevent quality of power provided through the power plug from being deteriorated by electromagnetic effect of the metal parts.
Claims10
A power plug, comprising:
- a terminal base having at least one conductive terminal and a ground terminal;
- an electric wire having core wires connected to the conductive terminal and the ground terminal, respectively;
- a cover integrally connected to the terminal base by at least two first screws;
- and
- a ground mechanism including a conductive member for connecting the first screws to the ground terminal, allowing the first screws to be grounded, wherein the conductive member has a central portion thereof being connected to the ground terminal, and two ends thereof respectively extending to two screw holes, allowing the first screws to be respectively screwed into the screw holes and come into contact with the conductive member.
