Abstract
The utility model discloses a flameproof film capacitor, relating to the technical field of capacitors. The flameproof film capacitor comprises a shell. The shell is internally provided with an upper locating sleeve and a lower locating sleeve, a core and impregnant are arranged between the upper locating sleeve and the lower locating sleeve, and a flameproof buffer part is arranged on the upper locating sleeve and the lower locating sleeve; a cover body is arranged above the upper locating sleeve arranged in the shell, a terminal is arranged at the upper part of the cover body, and the lower end of the terminal is connected with the core by penetrating through the cover body and a perforation of the upper locating sleeve through a connecting line; and a flameproof mechanism is arranged between the terminal and the core. The utility model solves the technical problem that the upper locating sleeve and the lower locating sleeve only fulfill the functions of location and insulation to the core of the capacitor, but do not have the action of promoting the flameproof performance of the capacitor in the existing capacitor and can fulfill the functions of location, insulation and flameproof buffer to the core at the same time.
Description
Technical field
The utility model relates to the capacitor technology field, especially a kind of explosion-proof film capacitor.
Background technology
The structure of existing film capacitor is such: it comprises a shell, and upper and lower positioning sleeve is installed in the enclosure, is provided with capacitor body and impregnating agent that the common metal winding film forms between upper and lower positioning sleeve; Last positioning sleeve top in the shell is provided with one explosion-proof, and explosion-proof top is provided with a lid.The lid upper end has terminal, and the terminal lower end is connected with rivet, and the explosion-proof line that welds on the rivet links to each other with the metal square through explosion-proof perforation.Should go up on positioning sleeve and also have corresponding perforation, thereby the lead-out wire of fuse on being is welded on the two poles of the earth of drawing capacitor on the metal square after passing the perforation of positioning sleeve; This lid by crimping outside on the shell by press seal in the enclosure.Therefore, this capacitor has explosion-proof performance preferably.
But the upper and lower positioning sleeve in existing product just has location and insulating effect to capacitor body, and the explosion-proof performance of product is not played effect.In the capacitor body self-love use that metallizing film winding forms as the film breakdown of pernicious moment macro-energy occurs, product internal pressure moment sharply increases, the bigger heat energy that the plastics plug of organic film or support film produces when the film instantaneous short circuit and melt extruding, positioning sleeve is gone up in the extrudate extruding, explosion-proof of last positioning sleeve extruding, explosion-proof extruding lid, when lid bore the squeeze pressure double action of product air pressure inside and fuse extrudate, explosion-proof mechanism had little time action, lid is ejected and cause security performance to lose efficacy.
The utility model content
The purpose of this utility model is to provide a kind of explosion-proof performance good film capacitor, the upper and lower positioning sleeve that solves existing product just has location and insulating effect to capacitor body, and the explosion-proof performance of product is promoted the technical problem that does not play effect, can play the effect of location, insulation and explosion-proof buffering to capacitor body simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of explosion-proof film capacitor, it comprises a shell, upper and lower positioning sleeve is installed in the enclosure, be provided with fuse and impregnating agent between the positioning sleeve up and down, should go up positioning sleeve and have explosion-proof buffering portion with following positioning sleeve, explosion-proof buffering portion of positioning sleeve upper end is double-layer staggered structure on it, and the explosion-proof buffering portion of following positioning sleeve lower end is equally distributed some buffering legs; Last positioning sleeve top in the shell is provided with a lid, and the lid upper end has terminal, and the terminal lower end is connected with fuse by the perforation that connecting line passes lid and last positioning sleeve; Has explosion-proof mechanism between this terminal and the fuse, this explosion-proof mechanism is the explosion-proof line that is connected between terminal lower end and the fuse, this explosion-proof line passes explosion-proof and is connected with weld tabs and is welded on the weld tabs, and this explosion-proof mechanism is arranged on lid and explosion-proof between the positioning sleeve up and down.
Compared with prior art, the effect that reaches of the present utility model is: the positioning sleeve upper end of going up of the present utility model is provided with explosion-proof buffering portion with following positioning sleeve lower end, makes upper and lower positioning sleeve not only have the effect of positioning core, also has the effect of explosion-proof buffering.Therefore, further promoted the explosion-proof performance of noinductive capacitor.

Among the figure: the last positioning sleeve of 11-, positioning sleeve under the 12-, 111,121-explosion-proof buffering portion, 2-lid, 21-terminal, explosion-proof of 3-, 4-weld tabs, 6-connecting line, 7-impregnant, 8-fuse, 9-shell, 91-crimping, 10-gilding layer, 13-soldering.
Embodiment
The utility model discloses a kind of explosion-proof film capacitor.As shown in Figure 1: it comprises a shell 9, and upper and lower positioning sleeve 11,12 is installed in shell 9, is provided with fuse 8 and impregnant 7 between upper and lower positioning sleeve 11,12; Last positioning sleeve 11 tops in the shell 9 are provided with a lid 2, and lid 2 upper ends have terminal 21, and terminal 21 lower ends are connected with fuse 8 by the perforation that connecting line 6 passes lid 2 and last positioning sleeve 11; The crimping 91 of this lid 2 by shell 9 upper ends by press seal in shell 9; Have explosion-proof mechanism between this terminal 21 and the fuse 8, this explosion-proof mechanism is arranged on explosion-proof 3 between lid 2 and the last positioning sleeve 11, and is connected the explosion-proof line between the weld tabs below End rivet under the terminal and explosion-proof.Characteristics of the present utility model are: positioning sleeve 11 has explosion-proof buffering portion 111,121 with following positioning sleeve 12 on this.This buffer part 111,121 can play cushioning effect in the explosion-proof process of capacitor, prevent that the squeeze pressure of fuse extrudate from acting on lid, further increases the explosion-proof security of capacitor product.
As shown in Figure 2, explosion-proof buffering portion 111 of positioning sleeve 11 upper ends can be double-layer staggered structure on this; As shown in Figure 3, the explosion-proof buffering portion 121 of this time positioning sleeve 12 lower ends is equally distributed some buffering legs.Certainly, the explosion-proof buffering structure of upper and lower positioning sleeve is not limited to said structure.
