Patent ID: 8747149

Claim:
An electrical connector plug comprising: a casing having: a power port with a middle terminal and a power terminal; a ground terminal mounted next to the power port; an output/input port mounted next to the ground terminal and having multiple upper terminals and multiple lower terminals, wherein a ground terminal is mounted every two of the upper terminals and of the lower terminals so as to isolate the other two of the upper terminals and of the lower terminals; a trough defined between the upper terminals and the lower terminals; a circuit board inserted in the trough of the casing and having power contacts, output/input contacts, a power terminal contact and an output/input terminal contact; a metal plate inserted between the power contacts and the output/input contacts of the circuit board to electrically connect to the ground terminal; and a metal housing composed of a front housing and a rear housing to entirely enclose the casing and to electrically connect to the metal plate such that the metal plate is able to transmit electromagnetic interference out via the metal housing.
