Abstract
The utility model discloses a three-pin safety plug. The three-pin safety plug includes a shell, and a fire line, a ground line and a zero line arranged in the shell. The three-pin safety plug also includes a first pin, a second pin and a third pin. The first pin is connected with the ground line through a first protective tube. The second pin is connected with the fire line through a second protective tube. The third pin is connected with the zero line directly. When current of an electric device connected through plug exceeds predetermined current, fuses in the protective tubes can be fused automatically, thereby disconnecting a circuit. At the same time, the ground line can prevent electricity leakage effectively.
Description
Technical field
The utility model relates to a kind of insurance three to be inserted, and antioverloading is anticreep.
Background technology
The plug that uses in the daily life stirs, and substantially all is that insulation crust and copper contact form, and the time spent, because the household electrical appliance that use are various, the frequent excess load of user is inserted a plurality of appliance sockets and made power source trip.But when single electrical equipment overloads, owing to the load that does not surpass total line, total lock still can not play a protective role, and the electrical equipment of this moment may go wrong, and easily causes electrical equipment to damage and other accidents.
The utility model content
For the problems referred to above, the utility model aims to provide a kind of tripod safety plug, and antioverloading is anticreep.
For realizing this technical purpose, scheme of the present utility model is: a kind of tripod safety plug comprises housing and the live wire, ground wire, the zero line that are built in enclosure interior; The first inserted sheet, the second inserted sheet and the 3rd inserted sheet, described the first inserted sheet is connected with ground wire by the first protective tube; The second inserted sheet is connected with live wire by the second protective tube; The 3rd inserted sheet directly is connected with zero line.
As preferably, the first inserted sheet, the second inserted sheet, the 3rd inserted sheet all adopts the thickening column construction.
The beneficial effects of the utility model are that when plug institute circuit closer exceeded current limit, the fuse in the protective tube can fuse open circuit automatically; Simultaneously ground wire insurance also can effectively prevent electric leakage.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is embodiment of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, a kind of tripod safety plug of the utility model specific embodiment, it comprises housing 9, live wire 6, ground wire 7, zero line 8.The first inserted sheet 1 is connected with ground wire 7 after also connecting the first protective tube 5 again; The second inserted sheet 2 is connected with live wire 6 after also connecting the second protective tube 4 again; The 3rd inserted sheet 3 directly is connected with zero line 8; Housing 9 wraps up their wherein, as shown in Figure 2; Wherein, the first inserted sheet 1, the second inserted sheet 2, the three inserted sheets 3 all adopt the thickening column construction.
The above; it only is preferred embodiment of the present utility model; not in order to limiting the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, all should be included within the protection range of technical solutions of the utility model.
