Abstract
The utility model relates to a pin for switching on the power supply of electric apparatus. In the existing pins, a plug piece is connected with a metal clamp which is connected with fuse wires, and the other end of the fuse wires is connected with the metal clamp which is connected with the electrical wire of electric apparatus. Because a fuse wire is connected between the plug piece and the electric wire of electric apparatus in series, various accidents of electric shock and damages of electric apparatus caused by the improper usage of electric apparatus can be avoided with the safety pin. So the safety pin solves the safety problem of using various electric apparatus.
Description
The present invention is a kind of plug that is used to connect appliances power source.
Plug on the existing electrical equipment can only play the effect of energized, and in the use of electrical equipment, and the electric wire of attachment plug and electrical equipment are in case electric shock accidents will take place in electric leakage, and is very dangerous, and when in a single day supply voltage increases, electrical equipment will be burnt out.
Purpose of the present invention provides a kind of multi-functional safety plug for improving above-mentioned every shortcoming exactly.
In the existing plug of forming by two inserted sheets, two shells and screw, usually the electric wire of inserted sheet and electrical equipment is direct-connected in plug, the present invention realizes like this, connect a metal holder that is connected with fuse on inserted sheet, the other end of fuse is connected with the metal holder of the electric wire of connecting circuit.Operation principle of the present invention is: power supply is connected by inserted sheet, metal holder, fuse, metal holder and electric wire and electrical equipment.It is to lean against the silk of insuring of connecting between the electric wire of inserted sheet and electrical equipment in the existing plug to reach the purpose of safe handling electrical equipment.
Whether the shell among the present invention can be a transparent insulation, blow so that judge fuse.
The present invention also can be that shell has aperture, and at two electrical equipment electric wires indicator light in parallel with the junction of plug.
Safety plug of the present invention, the fuse because it has been connected in plug, compare with existing plug, it has following advantage and good effect: use the present invention, when getting an electric shock because of the electric wire of attachment plug or electrical leakage, or supply voltage is when increasing, and the fuse among the present invention will blow moment, thereby cut off power supply, avoided loss of life or personal injury and electrical equipment to damage.So, the invention solves the safety problem that people use various electrical equipment.
Performance of the present invention describes with reference to the following drawings by an example now.
Fig. 1 is the safety plug schematic diagram; 1--shell wherein, 2--inserted sheet 3--clip, 4--presss from both sides the end, 5--jig arm, 6--cartridge fuse, 7--metal cap, 8--glass tube, 9--fuse, 10--electric wire, 11--screw.
Fig. 2 is the schematic diagram of another embodiment of safety plug: 12--aperture, 13--indicator light.
Fig. 3 is the exploded view of Fig. 1.
Shell 1, inserted sheet 2 and screw 11 are the part of existing plug among the present invention, cartridge fuse 6 is an existing product, clip 3 usefulness rubber-like sheet metals are made, the present invention has 4 clips 3, wherein the jig arm 5 of two clips 3 is used rivet with two inserted sheets 2 respectively, and two other clip 3 is connected with the electric wire 10 of connecting circuit respectively.Using method of the present invention and operation principle are; The two ends of two cartridge fuses 6 (metal cap 7) be pressed into respectively with inserted sheet 2 and clip 3 that electric wire 10 is connected in, shell 1 closes, the screw 11 of screwing on, the present invention is inserted in the supply socket, power supply is just connected by inserted sheet 2, clip 3, metal cap 7, fuse 9, metal cap 7, clip 3 and electric wire 10 and electrical equipment, and the present invention normally uses.When because of reasons such as voltage increases, electric leakage, electric shock, short circuits, blown fuse 9, get rid of reason, change new cartridge fuse 6 again, the present invention can continue to use.
