(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel safety plug to cause blown fuse to solve greatly because of flowing through electric current, causes power outage to miss the technical problem of other electrical appliance.
The technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that novel safety plug of the present utility model, mainly is made of plug, inserted sheet, live wire, live wire fuse, ground wire fuse, ground wire, screw, external cord, loam cake.
In shape, structure and combination thereof, the total essential features of novel safety plug of the present utility model and immediate prior art is: position, the base screw of loam cake is installed in the top position of plug, the bottom position electric wire of plug is connected an end position of external cord, be combined into the combining structure of hexagon shape, function has been to prevent that hand from running into the effect that internal wire gets an electric shock.One end position of inserted sheet inserts the jack position that is installed in plug, and the bottom position of plug is connected an end position of external cord with electric wire, is combined into the combining structure of hexagonal shape, and function has been that inserted sheet inserts the effect that socket is switched on.In shape, structure and combination thereof; the novel safety plug of the present utility model technical characterictic different with immediate prior art is: the end positions system of live wire fuse is connected the joint location of live wire; the one end position system of live wire is connected the bottom position of inserted sheet; be combined into the cascaded structure of linearity configuration, function has been the effect of energising and protection circuit.The end positions system of ground wire fuse is connected the joint location of ground wire, and the end position system of ground wire is connected the bottom position of inserted sheet, is combined into the cascaded structure of linearity configuration, and function has been the effect of protective circuit.Cause blown fuse with regard to what reached novel safety plug of the present utility model greatly because of flowing through electric current like this, cause power outage to miss the purpose of other electrical appliance:
The beneficial effect of the novel safety plug of utility model is that the utility model is to solve to cause blown fuse greatly because of flowing through electric current, cause the technical scheme that technical problem adopted that power outage missed other electrical appliance with existing with once had about having or not having that auxiliary protection ground connection is connected; Big group of two member connecting devices that the single utmost point is arranged, the link of band plug, for example the technology of banana plug group has been compared two advantages and improvement:
First; because the end positions system that has designed the live wire fuse in the technical scheme of novel safety plug of the present utility model is connected the joint location of live wire; the one end position system of live wire is connected the bottom position of inserted sheet; be combined into the cascaded structure of linearity configuration, so the technical problem of easier solution energising and protection circuit.
Second; because the end positions system that has designed the ground wire fuse in the technical scheme of novel safety plug of the present utility model is connected the joint location of ground wire; the one end position system of ground wire is connected the bottom position of inserted sheet; be combined into the cascaded structure of linearity configuration, so the technical problem of easier solution protective circuit.
(4) description of drawings:
Accompanying drawing provides the structural representation of novel safety plug of the present utility model:
Fig. 1: the plan structure schematic diagram that is novel safety plug of the present utility model;
Fig. 2: the side-looking structural representation that is novel safety plug of the present utility model;
The label declaration at each position in the schematic diagram:
1 plug, 2 inserted sheets, 3 live wires, 4 live wires insure 5 ground wire fuses
6 ground wires, 7 screws, 8 external cord, 9 loam cakes
(5) embodiment:
Below in conjunction with accompanying drawing, novel safety plug of the present utility model is caused blown fuse for realizing solving greatly because of flowing through electric current, the optimal way of the technical scheme that the technical problem that causes power outage to miss other electrical appliance is taked is described further:
Its static structure: see also accompanying drawing: as shown in the figure, novel safety plug of the present utility model mainly is made of plug 1, inserted sheet 2, live wire 3, live wire fuse 4, ground wire fuse 5, ground wire 6, screw 7, external cord 8, loam cake 9.Its major part inserted sheet 2, live wire 3, live wire fuse 4, ground wire fuse 5, ground wire 6, screw 7, external cord 8 are selected for use by market.Its plug 1 is a hexagonal shape, is material with plastics, through moulding processing and manufacturing.Its loam cake 9 is hexagonal shape, is material with plastics, through moulding processing and manufacturing.
In shape, structure and combination thereof, the total essential features of novel safety plug of the present utility model and immediate prior art is: position, the base screw of loam cake 9 is installed in the top position of plug 1, the bottom position electric wire of plug 1 is connected an end position of external cord 8, be combined into the combining structure of hexagon shape, function has been to prevent that hand from running into the effect that internal wire gets an electric shock.One end position of inserted sheet 2 inserts the jack position that is installed in plug 1, and the bottom position of plug 1 is connected an end position of external cord 8 with electric wire, is combined into the combining structure of hexagonal shape, and function has been that inserted sheet inserts the effect that socket is switched on.In shape, structure and combination thereof; the novel safety plug of the present utility model technical characterictic different with immediate prior art is: the end positions system of live wire fuse 4 is connected the joint location of live wire 3; the one end position system of live wire 3 is connected the bottom position of inserted sheet 2; be combined into the cascaded structure of linearity configuration, function has been the effect of energising and protection circuit.The end positions system of ground wire fuse 5 is connected the joint location of ground wire 6, and the end position system of ground wire 6 is connected the bottom position of inserted sheet 2, is combined into the cascaded structure of linearity configuration, and function has been the effect of protective circuit.
Below by using method, further set forth the dynamic structure relation of this practical novel safety plug: in use, when needs insert plug work, according to electrical principles, at first will put into 1 li of plug with the line of fuse, close the lid 9 and tighten then, insert socket more then, thereby finish the task of energising work.Cause blown fuse with regard to what realized novel safety plug of the present utility model greatly because of flowing through electric current like this, cause power outage to miss the technical scheme of the technical problem of other electrical appliance.
Realize that preferred plan of the present utility model is is material with plastics and electric wire, utilize the basic equipment of appliance switch factory, take to produce by batch greatly, the demand with the supply daily life so just can realize novel safety plug practical value of the present utility model and economic worth better.
