Abstract
The utility model provides a touching type safety power supply socket, comprising a base and a socket body composed of an upper cover with plug jacks. The utility model is characterized in that a conductive contact piece is arranged in the socket body, and the conductive contact piece is connected with the head of a power conducting wire. A conductive elastic plug-in unit which doesn't correspond to the plug jacks or contact with the conductive contact piece is also arranged in the socket body. When the plug isn't inserted into the plug jacks, the conductive elastic plug-in has no electricity. The conductive elastic plug-in unit can contact the conductive contact piece after the plug is completely inserted into the plug jacks, and thus, the power is switched on.
Description
The utility model relates to the supply socket that a kind of power consumption equipment is connected with power supply, particularly a kind of press-contacting type safety power source plug socket.
Existing supply socket, the electrically conductive elastic plug-in unit in the receptacle sockets all directly are connected with power supply, and when plug did not insert, the electrically conductive elastic plug-in unit was charged, in electric equipment and the more occasion of socket.Employed lead or metal device are strayed into easily to cause in the receptacle sockets and get an electric shock or equipment breakdown, children, blind person and when using socket in the dark, all might touch the electrically conductive elastic plug-in unit in the receptacle sockets, cause electric shock accidents, and the existing power supply socket only there is the function of energized, can not shows whether switch on, and have the supply socket of power indicator, its complex structure needs the transformer transformation, and electric appliance load power is had specific scope restriction.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of press-contacting type safety power source plug socket is provided.
The utility model provides a kind of press-contacting type safety power source plug socket, the socket that comprises the loam cake composition of base and band jack, be provided with conductive contact blade in the socket, conductive contact blade is connected with the power lead head, also have in the socket corresponding with jack not with the contacted electrically conductive elastic plug-in unit of conductive contact blade, when plug did not insert jack, the electrically conductive elastic plug-in unit was not charged, the electrically conductive elastic plug-in unit can contact with conductive contact blade after plug inserted jack fully, thus energized.
Be in series with the light-emitting diode, rectifier diode D and the current-limiting resistance R that show as power supply between the above-mentioned two electrically conductive elastic plug-in units, the conducting of diode displaying electric current and disconnection.
Above-mentioned conductive contact blade places in the two interior insulation tanks of base, and two electrically conductive elastic plug-in units do not place conductive contact blade top in contact with conductive contact blade.
Above-mentioned conductive contact blade also can place in the two interior insulation tanks of loam cake, and two electrically conductive elastic plug-in units do not place the centre of two conductive contact blades in contact with conductive contact blade.
The utlity model has following characteristics:
1. during socket emptying aperture of the present utility model (not inserting plug), not charged, can prevent that the person from getting an electric shock, safe and reliable.
2. the utility model is on the small-sized single-phase double wire system porous socket body of the universal standard, and conductive contact blade is set, and electrically conductive elastic plug-in unit and power indicator form, and it makes simple, is easy to promote.
The outline drawing of Fig. 1 first kind of embodiment of the present utility model.
Fig. 2 is the structural representation after outline drawing shown in Figure 1 removes loam cake.
Fig. 3 is the profile of structural representation shown in Figure 2 along the A-A section.
