Description
Technical Field
The utility model belongs to the technical field of the plug device, concretely relates to take safety plug of fuse.
Background
The connector of the general electric appliance and the plug of the electric appliance are called as a plug. A plug and socket for domestic AC power supply has a male connector in the shape of rod or copper plate and a female connector-type power supply socket with slot or concave hole. The dimensions are an important technical requirement in relation to whether the plug and socket and the converter can be used safely and whether the universal interchangeability requirement is met to avoid misinsertions. When some precise instruments or electrical equipment needing strict current-limiting protection are used, the overcurrent protector installed on the indoor air switch is difficult to realize the overcurrent protection function, and the existing plug does not have the overcurrent protection function. Therefore, designing a plug capable of performing overcurrent protection is an important problem that needs to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide the safety plug of taking the fuse.
Take safety plug of fuse, including fuse, plug iron sheet, iron sheet fixed plate, its characterized in that: the plug iron sheet is fixed on the iron sheet fixed plate, the plug iron sheet stretches out from the back of iron sheet fixed plate, the back of iron sheet fixed plate is fixed with the boss, be equipped with the cylindricality cavity on the boss, the back of plug iron sheet stretches into in the cylindricality cavity, the fuse is equipped with to the encapsulation in the cylindricality cavity on the boss, the first end of fuse compresses tightly with the back of plug iron sheet, the back of boss is fixed with platelike clamp plate, the clamp plate passes through the fix with screw on the boss, be fixed with binding post on the clamp plate, in the cylindricality cavity is inserted to binding post's front portion, the second end of fuse compresses tightly with binding post's front portion, binding post's rear portion is connected with the front end of wire, the rear end of wire is connected with the socket.
Preferably, the pressing plate and the boss are poured in the rubber pouring block.
Preferably, the outer side of the lead is provided with an insulating wire layer.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses when using for precision instruments or need carry out the electrical equipment wiring of strict current-limiting protection and use, in electrical equipment's plug inserted the socket, the plug iron sheet inserted supply socket, in case electrical equipment takes place the short circuit or overflows, the fuse fuses plays and carries out overcurrent protection's effect to electrical equipment. The utility model has the advantages of simple structure and low cost; the utility model discloses a fuse realizes overcurrent protection, has the advantage that the security is good. During processing, the fuse is firstly placed in the cylindrical cavity on the boss, the pressing plate is fixed, the wiring terminal is connected with the wire in a crimping mode, and the rubber pouring block is poured in a pouring mode.
Drawings
Fig. 1 is a schematic structural view of a safety plug with a fuse according to the present invention.
Fig. 2 is a schematic diagram of the structure of the middle socket of the present invention.
In the figure, 1, a socket, 2, an insulating wire layer, 3, a lead, 4, a rubber pouring block, 5, a wiring terminal, 6, a pressing plate, 7, a fuse, 8, a plug iron sheet, 9, a boss, 10 and an iron sheet fixing plate.
Detailed Description
Referring to fig. 1 and 2, the safety plug with a fuse includes a fuse 7, a plug iron sheet 8, and an iron sheet fixing plate 10, and is characterized in that: the plug iron sheet 8 is fixed on the iron sheet fixing plate 10, the plug iron sheet 8 extends out from the back of the iron sheet fixing plate 10, a boss 9 is fixed on the back of the iron sheet fixing plate 10, a cylindrical cavity is arranged on the boss 9, the back of the plug iron sheet 8 extends into the cylindrical cavity, the fuse 7 is sealed in the cylindrical cavity on the boss 9, the first end of the fuse 7 is pressed with the back of the plug iron sheet 8, the back of the boss 9 is fixed with a plate-shaped pressing plate 6, the pressing plate 6 is fixed on the boss 9 through a screw, the wiring terminal 5 is fixed on the pressing plate 6, the front part of the wiring terminal 5 is inserted into the cylindrical cavity, the second end of the fuse 7 is pressed against the front part of the wiring terminal 5, the rear part of the wiring terminal 5 is connected with the front end of the wire 3, and the rear end of the wire 3 is connected with the socket 1.
The pressing plate 6 and the boss 9 are poured in the rubber pouring block 4.
And an insulating wire layer 2 is arranged on the outer side of the lead 3.
The utility model discloses a theory of operation is:
the utility model discloses when using for precision instruments or need carry out the electrical equipment wiring of strict current-limiting protection and use, in electrical equipment's plug inserted socket 1, plug iron sheet 8 inserted supply socket, in case electrical equipment takes place the short circuit or overflows, fuse 7 fusing plays the effect of carrying out overcurrent protection to electrical equipment. During processing, the fuse 7 is firstly placed in the cylindrical cavity on the boss 9, the pressing plate 6 is fixed, the wiring terminal 5 is connected with the lead 3 in a crimping mode, and the rubber pouring block 4 is poured in a pouring mode.
It should be noted that, when the safety plug is a three-hole plug, the fuse 7 does not need to be additionally arranged at the rear part of the plug iron sheet 8 on the zero line, and only the fuse 7 needs to be additionally arranged at the rear parts of the plug iron sheets 8 on the live line and the zero line.
