<p>A general power plug structure allows a user to easily insert a plug into a socket (or receptacle) with one hand, but it is very difficult and inconvenient for the user to pull out or separate the plug without using both hands, that is, with only one hand, due to a contact force and a friction force of an electrode of a corresponding female portion (socket or receptacle) which has elasticity for contact reliability between the electrode and an earth electrode. Accordingly, even if the plug has to be pulled out or separated for energy conservation or safety reasons, the plug is usually left in the socket without being pulled out or separated, and thus it is difficult to accomplish the objectives, such as energy conservation, electric shock prevention and the like. Furthermore, even when trying to simply measure a current or to check an overload using a hook-on ammeter while power is supplied to a load through a power plug (or through a socket or a multi-tap), the hook-on ammeter cannot be inserted at the same time, and thus the objective of the present invention is to solve such problems. To solve the problems of the prior art, the objective of the present invention is to provide a power connector having both pushable and pullable structures in a power plug such that the plug can be easily pulled out or separated with one hand, and at the same time, having a structure in which a space is formed in the lateral direction of the power connector such that a hook-on ammeter (or a current transformer) can be inserted into the space so as to measure a current for a smart grid, and in which electrode wires are separately buried in respective poles.</p> |
