Abstract
The utility model provides a metal film capacitor belonging to the capacitor field, which comprises terminals, a terminal base sealing ring, a top cover, and explosion-proof wires, connecting wires, a top cover sealing ring, an upper plastic sleeve, a mandrel, a capacitance core, a casing, and a lower plastic sleeve. An inward-folded groove is arranged on the upper portion of the capacitor casing, one terminal is directly connected with the capacitance core through the explosion-proof wire, and the other one terminal is directly connected with the other end of the capacitance core through the connecting wires which are passed through the central hole of the capacitor mandrel. A groove is arranged between the inward-folded groove on the upper portion of the capacitor casing and the top portion of the casing. The utility model has simple structure, which is a metal film capacitor with good leak tightness and high safety.
Description
The utility model metallic film capacitor belongs to capacitor area, particularly relates to a kind of metallic film capacitor.
The bakelite seat is adopted in American capacitor terminal that uses and the insulation between the iron covering now, the electric capacity lid adopts tinplate, get rusty easily, rivet, explosion-proof line will be passed through in the two poles of the earth of electric capacity, lead is connected with fuse the two poles of the earth again, the structure member of capacitor is many, as breaks down, and sealing effectiveness can damage, rush down leakage easily, poor stability.
The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of structure comparatively simple, good airproof performance, safe metallic film capacitor.
The purpose of this utility model reaches by following measure, it is by terminal, end seat sealing ring, the nest nail, loam cake, explosion-proof line, connect lead, the loam cake sealing ring, on mould cover, impregnating agent, plug, the bag core paper, capacitance core, shell, under mould cover and form, in the shell upper of capacitor the groove of one invagination is arranged, adopt end seat sealing ring to be connected with the nest nail between terminal and the loam cake, a terminal directly is connected with capacitance core with explosion-proof line, another terminal directly is connected with the capacitor core other end by electric capacity plug centre bore with connecting lead, groove in the invagination of capacitor upper is explosion-proof stretch slot, and when capacitance current was excessive, the inner air pressure that produces stretched the groove of invagination, can not cause sealing effectiveness to destroy, do not rush down leakage, fail safe is good, is provided with a groove between the groove of the shell upper invagination of capacitor and capacitor case top, be used for fixing the sealed plastic loam cake, the sealed plastic loam cake adopts hardness big, and resistant to elevated temperatures vinyl cover does not need to isolate with the bakelite seat, use between capacitance core and the shell to mould cover and mould down cover and insulate, last covering the loam cake sealing ring is set, enhanced leaktightness prevents capacitance leakage.
The utility model is simple in structure, is a kind of good airproof performance, and after breaking down, sealing effectiveness can not damage, safe metallic film capacitor.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is by terminal 1, end seat sealing ring 2, nest nail 3, loam cake 4, explosion-proof line 5, connect lead 6, loam cake sealing ring 7, on mould cover 8, impregnating agent 9, plug 10, bag core paper 11, capacitance core 12, shell 13, under mould cover 14 and form, use between capacitance core and the shell and mould cover and mould the cover insulation down, adopt end seat sealing ring to follow closely between terminal and the loam cake and be connected with nest, a terminal directly is connected with capacitance core with explosion-proof line, another terminal directly is connected with the capacitor core other end by electric capacity plug centre bore with connecting lead, in the shell upper of capacitor the explosion-proof stretching groove 15 of one invagination, ring of explosion-proof stretching groove formation of invagination is arranged, between the groove of the shell upper invagination of capacitor and capacitor case top, be provided with a groove 16, be used for fixing the sealed plastic loam cake, last covering loam cake sealing ring 7 be set, when capacitance current is excessive, the inner air pressure that produces stretches the groove of invagination, prevents capacitance leakage.
