Description
Technical field
The invention belongs to the electrical appliance technical field, be specifically related to a kind of anti-fire mechanism of AC capacitor, be used for preventing the accident on fire that capacitor causes because of abnormal conditions in the course of the work
Background technology
The on fire of household electrical appliance is a breakneck thing, and initiation fire brings massive losses for household electrical appliances user's the security of the lives and property very easily therefrom.This wherein uses the household electrical appliances of load motor, such as refrigerator, air-conditioning, washing machine etc., has the reason of fire of quite a few to come from employed AC capacitor on the monophase machine.AC capacitor is because it realizes the restriction of principle,, material aging too high in overvoltage, overcurrent, ambient temperature, material exist in the situations such as flaw, be very easy to occur the situations such as puncture, electric leakage, heating, when this situation lasts till to a certain degree, the accident such as will blast, on fire causes household appliances on fire.
To on fire existing certain safeguard procedures of ac capacitor, adopt metal fireproof housing, the encapsulation of inner use epoxy sealing etc. such as the outside on the Vehicles Collected from Market, these technology have its pluses and minuses separately, but all can not well solve the fire safety problem of capacitor.As adopt the metal fireproof housing can play preferably the fireproof effect, but the metal-back that can play well fire-proof and explosion-proof effect knows from experience to product and increases cost, also increased the danger when electric capacity is blasted simultaneously; And the epoxy sealing encapsulation has certain fireproofing function to electric capacity, but effect can not be entirely satisfactory.
In view of above-mentioned prior art, be necessary the fire-proof function of existing AC capacitor is improved, technical scheme described below produces under this background
Summary of the invention
Task of the present invention is to provide a kind of and helps to stop on fire and use and ensure safety and be conducive to avoid increase cost and use the anti-fire mechanism that embodies cheap AC capacitor.
Task of the present invention is finished like this, a kind of anti-fire mechanism of AC capacitor, described AC capacitor comprises an AC capacitor body, this AC capacitor body comprises two electrode leads to client, described anti-fire mechanism comprises the electrode spring sheet, electrode leading-off rods and housing, housing is fixed on the described AC capacitor body, one end of electrode spring sheet is electrically connected with described electrode leads to client, and the end of the other end of electrode spring sheet by solder joint and electrode leading-off rods is welded to connect, the other end of electrode leading-off rods leans out outside the described housing, and be equipped with one for the spacing regulating part that the electrode leading-off rods is applied the pulling force that makes the electrode spring sheet remain in deformation state, this spacing regulating part contacts with the outer wall of described housing, wherein, the material of described solder joint is scolding tin.
Technical scheme provided by the invention is because the electrode spring sheet that will be electrically connected with electrode leads to client is that solder joint and the electrode leading-off rods of scolding tin is welded to connect by material, again because the fusing point of scolding tin is 150-250 ℃, the AC capacitor body certainly exists the process that a temperature rises to ignition point before on fire, and the ignition point that consists of the material of AC capacitor body all is higher than the melting point of solder joint, therefore in the temperature uphill process before the AC capacitor body is on fire, the situation that the solder joint fusing between electrode leading-off rods and the electrode spring sheet will inevitably occur, the electrode spring sheet that is in deformation state is replied, solder joint disconnects, cause AC capacitor body dead electricity, thereby stop the heating up process of AC capacitor body, avoid the on fire of AC capacitor body, thereby can guarantee safety; Overall structure simply is not enough to cause the remarkable increase of manufacturing cost.

Embodiment
In order more clearly to describe technical spirit of the present invention and effect, the below provides the specific embodiment of the present invention.
Ask for an interview Fig. 1, provided an AC capacitor body 1, according to common practise, AC capacitor body 1 has a pair of (namely two) electrode leads to client (industry also claims electrode lead-out pins), in the drawings, although what the applicant had only illustrated AC capacitor body 1 one ends is that the shown position state is towards an electrode lead-out pins 11 of a upper end, but can't to the other end be the shown position state towards under the understanding of an electrode leads to client 11 of an end consist of puzzledly, following description all is towards the upper end of location status shown in Figure 1 for AC capacitor body 1.
The anti-fire mechanism that provides comprises an electrode spring sheet 2, one electrode leading-off rods 3 and a housing 4, housing 4 is fixing with AC capacitor body 1, and preferably fix by the mode of welding and the end face of AC capacitor body 1, aforesaid electrode leads to client 11 is covered by housing 4 and protects, that is to say that electrode leads to client 11 is positioned at the shell chamber 41 of housing 4, electrode spring sheet 2 is positioned at shell chamber 41, one end of this electrode spring sheet 2 is that the lower end of shown position state preferably is electrically connected in the mode of welding with electrode leads to client 11, and the other end of electrode spring sheet 2 to be the upper end of shown position state be welded to connect by solder joint 21 end (diagram left end) with electrode leading-off rods 3, the material of solder joint 21 is scolding tin, the other end of electrode leading-off rods 3 (diagram right-hand member) is stretched over outside the housing 4, namely lean out shell chamber 41, and this other end end at electrode leading-off rods 3 preferably is equipped with a spacing regulating part 31 with thread fiting mode, these spacing regulating part 31 preferred nuts that use, but also can use similar equivalence parts, spacing regulating part 31 supportings are kept out shortly on the outer wall of housing 4, applied towards the pulling force of the direction of arrow shown in Figure 15 and used by 31 pairs of electrode leading-off rods 3 of this spacing regulating part and make electrode spring sheet 2 be in deformation state, the direction of distortion is towards the direction of arrow 5.The other end at AC capacitor body 1 is provided with aforesaid anti-fire mechanism equally.
Referring to Fig. 2, when the solder joint of being filled the post of by scolding tin 21 between electrode spring sheet 2 and the electrode leading-off rods 3 melted because of high temperature, electrode spring sheet 2 broke away from and being connected of electrode leading-off rods 3 because of its elasticity, thereby makes AC capacitor body 1 dead electricity.
Referring to Fig. 3, the complete product schematic diagram after two electrode leads to client 11 places at AC capacitor body 1 two ends have all implemented fire resistive construction of the present invention.
In sum, technical scheme provided by the invention has overcome the shortcoming in the prior art, objectively finished the invention task and embodied the technique effect described in the superincumbent technique effect of the applicant hurdle, thereby to can yet be regarded as is a ultimate attainment technical scheme
