Patent ID: 7210954

Claim:
An electrical connector plug for connecting to an electrical connector receptacle having electrical receptacle contacts, a metal electrical receptacle shell, and nuts electrically connected with the metal electrical receptacle shell, said electrical connector plug comprising: an insulative connector housing having a central rectangular body, and two locking sections extending laterally in opposite lateral directions from said central rectangular body, said two locking sections having screw-receiving holes formed respectively therethrough; electrical plug contacts mounted to said central rectangular body of said insulative connector housing for electrically contacting with the electrical receptacle contacts of the electrical connector receptacle; and a metal electrical connector plug shell electrically covering both said central rectangular body of said insulative connector housing and said locking sections of said insulative connector housing; wherein said metal electrical connector plug shell includes contact surfaces respectively having screw-receiving through-holes therein, said contact surfaces being configured so that said screw-receiving through-holes thereof are respectively aligned with said screw-receiving holes formed in said locking sections; and wherein metal lock screws respectively extend through said screw-receiving holes formed in said locking sections and respectively extend through said screw-receiving through-holes formed in said contact surfaces of said metal electrical connector plug shell, such that said metal lock screws respectively electrically contact said contact surfaces of said metal electrical connector plug shell and are configured and arranged to threadedly engage in the nuts of the electrical connector receptacle in order to secure said electrical connector plug to the electrical connector receptacle and provide an electrical conduction path from said metal electrical connector plug shell to the metal electrical receptacle shell via said lock screws and the nuts.
