Abstract
The utility model relates to an overload protecting single phase plug, which is characterized in that a fuse (6) is arranged between the L electrode bayonet pin (2) and the L electrode conductive wire (11) on the basis of the original plug structure. In this way, when the electric appliance uses the overload protecting single phase plug and the electric current of the electric appliance exceeds the fusing current of the fuse (6), the fuse (6) can automatically blow out and can not cause the damage even fire of the electric appliance. An accident caused by the short circuit of circuit line and the damage of the whole system because of foreign matter in the household electrical appliance, the quality problem of the household electrical appliance or improper use, etc. can not happen.
Description
The utility model relates to single-phase three utmost point non rewirable plugs of a kind of single-phase three-terminal polarized plus plug, especially overload protection.
At present, each family of China, hotel etc. all have more electrical appliance, as: refrigerator, air-conditioning, washing machine etc., they the time all share a fuse in work, and the blowout current of this fuse is higher, in this scope when wherein an electrical appliance breaks down, often fuse can not reach blowout current, cause the damage of electrical appliance so probably, in addition on fire, make entire circuit cause fire.
The purpose of this utility model is to provide a kind of overload protection single-phase three utmost point non rewirable plugs; when the electric current of single electrical appliance surpasses 2-3 times of rated current; be contained in single-phase three utmost point non rewirable plugs of overload protection fuse automatically fusing make and used electrical appliance shielded single electrical appliance circuit breaker.
In order to achieve the above object; single-phase three utmost point non rewirable plugs of the utility model overload protection are connected by: insulating body, " L " utmost point latch, " N " utmost point latch, earth electrode latch and with respective wire etc. to be formed, and is characterized in being furnished with fuse between " L " utmost point latch and " L " polar conductor.
Owing on former single-phase three utmost point non rewirable plug " L " polar curve roads, adorned a fuse, household electrical appliance are when using this plug, when single electrical appliance breaks down, just energy auto-cutout of circuit, can not cause the damage of electrical appliance even on fire, can not enter in the household electrical appliance because of foreign matter yet, or because of the quality problems of household electrical appliance, improper uses etc. cause line short, make whole system damage and the generation that causes the accident, while the utility model reasonable in design, volume is small and exquisite, the replacing fusible link is convenient, is that electrical appliance is connected the most desirable with power supply, safest attachment plug.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail
Fig. 1 is the single-phase three grades of non rewirable plug structure cutaway views of the utility model overload protection
As shown in the figure, single-phase three utmost point non rewirable plugs of the utility model overload protection are made up of insulating body 7, " L " utmost point latch 2, " N " utmost point latch 9, earth electrode latch 1 etc." N " utmost point latch 9 links to each other with " N " polar conductor 10, and earth electrode latch 1 links to each other with earth electrode lead 12, the position of three latches single-phase, the 3-phase plug jack technology condition that conforms to GB2099 triangular in shape.Centre in insulating body 7 a bodies side of " L " utmost point latch 2 partially is provided with condom 5, shape is cylindrical, diameter is more slightly larger than fuse 6, bottom at condom 5 is equipped with " U " shape spring 8, one end of " U " shape spring 8 links to each other with " L " polar conductor 11, and another spring face touches with the bottom connection that is placed on the fuse 6 in the condom 5.The other end of " L " utmost point latch 2 is rectangular in shape on condom 5 holes of support arm injection moulding in insulating body 7, support arm is along being shaped on screw 4 on condom 5 centerline holes, is furnished with screw 3 in the screw 4, screw 3 bottoms contact with fuse 6 tops, and screw 3 tops are lower than plane on the insulating body 7, " L " utmost point latch 2 and " L " polar conductor 11 are fused, under the effect of " U " shape spring 8 elastic force, make fuse 6 and screw 3 keep excellent contact.Like this when " L " utmost point latch 2 has electric current, electric current is just by " L " utmost point latch 2, enter " L " polar conductor 11 by screw 3, fuse 6, " U " shape spring 8.
