The connecting hole of circuit connection.
Arc-chutes 8, are moulding, several grid are provided with it, for arc extinguishing.Offered at the top of arc-chutes with
The exhausting-gas hole 81 that grating space is connected.Arc-chutes 8 can be contained in limit card slot 28 in assembling.
Fuse cover board (not shown), is provided with the fin of corresponding limit card slot 29 on it, when mounted, fin is embedding
Pack into limit card slot 29.
After fuse all parts assemble, the position relationship of all parts is：The gas for being arranged with fastener fills
Put each circle that MGG is contained in the semicircular arc groove formation of left outside shell semicircular arc groove (21,22,23) and corresponding right casing
In the accommodating cavity of shape, the electrode tip of MGG is with the junction of pyrotechnics coyote hole because having step, semicircular arc groove 21 and semicircular arc groove
The limited step formed between 22 then just matches with MGG electrode tips with the step at pyrotechnics coyote hole to be compressed, and realizes and MGG is carried out
Position restriction, prevents MGG from dropping from accommodating cavity.The screens fin 51 of fastener on MGG just nests into left outside
The circular accommodating cavity with positive six aspects that shell semicircular arc groove 23 is formed with corresponding right casing upper half arc-shaped slot
In it is positioned.Due to the presence of six aspects of the accommodating cavity, it can prevent fastener from being rotated relative to shell.Punch is arranged
On fastener, the cylindrical drum part of punch is located at the semi arch of the semicircular arc groove 25 and corresponding right casing of left outside shell
In the circular accommodating cavity that shape groove 31 is formed, the both ends of stamping knife are then located in limiting groove 30 and limiting groove 35 respectively, stamping knife
Under external force, upper and lower displacement can be done along two limiting groove.Melt 7, its roof are contained in positioned at semicircular arc groove 25
In limit card slot 27 on the upper surface of the accommodating cavity formed with semicircular arc groove 31, its roof both ends passes through limited block respectively
271 and limited block 34 stick into limiting groove 71 to melt roof carry out clamping positioning.The two side of melt is located at semicircle respectively
In retaining groove 26 between accommodating cavity and the side wall of shell that arc groove 25 and semicircular arc groove 31 are formed, and it is close to shell
The inner wall of front-rear side walls.The contact knife of melt then stretches out housing exterior.The groove 74 of V-structure on melt is placed exactly in stamping knife
Top, and keep certain distance with it.In limit card slot 28 on melt, arc-chutes 8 are equipped with.
The present invention operation principle be：The electrode tip of gas generating unit MGG is connected with exterior sensor, and melt touches
Knife is connected with circuit.When being impacted or high current is when abnormal signal, sensor sends a signal to electrode tip triggering igniting dress
Igniting is put, promotes pyrotechnics coyote hole pyrotechnic composition to react and generates a large amount of gases at high pressure, and discharged from gas release end, gases at high pressure
Punch is impacted after fastener, and drives punch to move upwards, under powerful active force, stamping knife is moved and collided molten upwards
The groove 74 of the V-structure of body, is cut off, and after melt is cut off, one part is in gravity along the shallow grooves on melt
Hang downwards under effect.Gas then flows to arc-chutes and through going out along the opening after the air discharge duct and melt fracture on shell at this time
Arc chamber is spilled over to outside fuse shell；Meanwhile the electric arc produced at melt is also blown into arc-chutes under the action of gas
Carry out arc extinguishing.
Such fuse the advantage is that compared with the fuse commonly only to be fused by high current：Rushed when receiving external force
Hit or during other shocks, it can make melt fracture with fast reaction, so that disconnecting circuit, realizes protective effect, have quick ring
Speed is answered, the disconnecting circuit within the shortest time, pair equipment being connected with circuit is protected.This is that common fuse is incomparable
Advantage.
