US Patent 7121869 Power cord electric connection structure

A power cord electric connection structure includes a power cord and a terminal socket that are electrically connected in a vertical direction. The power cord has a connecting portion in which the conductive core is bare and exposed outside the insulation layer. The terminal socket has a coupling trough which contains a conductive terminal to form a plane contact with the bare conductive core so that a secure electric connection is established, and wiring management of the power cord and terminal socket is easier.
