Background technology

Supply socket is as a kind of daily living article, in life, be widely used, therefore its fail safe enjoys people's attention, socket commonly used now is owing to the pin for the ease of attaching plug can be inserted in the jack of socket smoothly, the internal diameter of jack that generally is socket is greater than the external diameter of pin, and the place is provided with lead angle at jack, but this structure has also been brought potential safety hazard, because between pin and jack inwall, exist certain clearance, in the plug process of socket, be easy to from the gap, bring into impurity, cause short circuit, more dangerous is that child might extend into finger in the jack, and the danger of electric shock is arranged.Traditional socket simultaneously is a plurality of socket units in series or back in parallel to be had the power line of attaching plug by one be connected with socket on being connected power supply, and it is aesthetic in appearance to influence socket, and is not easy to each socket unit is controlled, and security performance is low.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective in the prior art: provide a kind of easy to use, external form is more attractive in appearance, do not need to adopt power line to be connected, and can guarantee the socket of safety in utilization with the socket on being connected power supply with attaching plug.

For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of socket is provided, comprise bottom, fixedly connected cover with bottom, be equiped with the live wire pin of pegging graft on the described bottom with supply socket, earth pin, zero line pin, the live wire bus that is connected with the live wire pin that is embedded with at interval in the bottom, the ground wire bus that is connected with earth pin, the zero line bus that is connected with zero line pin, be arranged at intervals with in the bottom and described live wire bus, the ground wire bus, the socket unit that the zero line bus connects offers on the cover and corresponding socket hole, each socket unit.

Also comprise the safeties on the described bottom that is arranged on the described bottom, be arranged on the anti-electric shock apparatus that inboard each the socket unit of cover adapts.

The beneficial effect of socket described in the utility model is: by combining together with live wire pin, earth pin, zero line pin and the socket that supply socket is pegged graft, do not need to adopt power line to be connected with the socket on being connected power supply with attaching plug, be not connected with socket owing to do not need employing to have attaching plug, make the external form of socket more attractive in appearance; Safeties on the described bottom on the described bottom are arranged on the anti-electric shock apparatus that inboard each the socket unit of cover adapts, and have guaranteed the fail safe that this socket is used; Each socket unit all is equiped with control switch, is convenient to each socket unit is controlled, and simultaneously, each socket unit also is equiped with indicator light, is convenient to power supply situation is made comments and instructions.During use, live wire pin, earth pin, the zero line pin of socket described in the utility model are inserted in the jack of supply socket, each socket unit to described socket powers, again the attaching plug of power consumption equipment being inserted corresponding socket unit can use, and can control each socket unit by control switch.

Below in conjunction with drawings and Examples socket described in the utility model is described further:
