Electric plug and electrical socket

An embodiment of the utility model provides an electric plug and electrical socket. This electric plug, it includes: plug electric connector, plug electric connector's one end is used for being connected to the cable, and the other end is used for being connected to during to the electrical socket of adaptation the socket electric connector of electrical socket at electric connector assembly, plug housing, plug housing surround the partly at least of plug electric connector, and the clamping, the clamping setting is in on plug housing's the opposite side for electric connector assembly during to the electrical socket with the electrical socket block. The utility model provides an electric plug have can with the clamping of the electrical socket block of adaptation, rely on this clamping firmly to couple together electric connector between them, the influence of avoiding electric connector contact failure to cause, for example system's unstability, shutdown and/or data transmission suspend and so on. In addition, electric plug and electrical socket's connected mode easy operation is easily capable, if before the connection with both alignments can, do not receive the restriction of installation condition basically.
