Description

Technical Field

[0001] The utility model relates to the field of plug boards, in particular to an expansion plug board. Background Art

[0002] Existing expansion plug boards are divided into mobile and fixed types; the mobile type generally has a plug board body with a cable and a plug, so the plug board body can be moved and arranged as needed; the fixed type has pins set on the plug board body, and the pins are directly plugged into the socket on the wall; therefore, the fixed type of plug board is fixed entirely by the connection between the pins and the socket. Since the panel of a general socket protrudes out of the wall, after the pins on the back of the plug board are fixed to the socket, the back of the plug board only forms a small range of fitting support with the panel of the socket, and there is often a gap between most of the back of the plug board and the wall. When plugging and unplugging, the plug board is easily tilted and falls off due to uneven force. In addition, the plug board and the socket are only connected by the pins, and its instability increases the possibility of damage to the pins. Utility Model Content
