Description
Technical field
The utility model relates to electric capacity field, particularly a kind of electric capacity with explosion-proof shear knife.
Background technology
Prior art noinductive capacitor is equipped with physics blast resistance construction, when two electrodes of capacity cell are breakdown, container or housing change because of the air pressure inside dilatancy that raises, until be arranged on the wire of metal inner casing, break, thereby reach open-circuit condition, avoid electric capacity to pop because of overload.Existingly for explosion-proof wire, generally adopt diameter to be less than the tinned wird of 0.7mm, but diameter is less than the demand that the tinned wird of 0.7mm cannot meet large current product, if directly adopt tinned wird more than diameter 1.0mm, current capacity has met the demand of large current product, but wire diameter is large, be difficult for breaking, do not have explosion-proof.
Utility model content
In order to address the above problem, the utility model provides a kind of electric capacity with explosion-proof shear knife, comprises anti-explosion filaments shear knife, can meet the demand of large current product, can play good explosion-proof again.Concrete technical scheme is as follows:
The electric capacity with explosion-proof shear knife, comprises stem, unit of plastic, copper sheet, anti-explosion filaments and anti-explosion filaments shear knife; Electric capacity comprises fuse, and stem is arranged at capacitive head, and copper sheet arranges fuse top, and unit of plastic arranges fuse top and is positioned at copper sheet top, and anti-explosion filaments shear knife comprises construction section and acting section, and construction section is provided with installing hole, and acting section is provided with tool bore and blade; Anti-explosion filaments shear knife is arranged at stem bottom, and anti-explosion filaments one end is fixedly connected on stem, and the other end, through tool bore, twines a circle around blade, then is fixedly connected on copper sheet.
Described blade flare.
Described explosion-proof shear knife is L shaped.
The diameter of anti-explosion filaments is 1.0mm～2.5mm.
Anti-explosion filaments is fixedly connected on stem bottom and copper sheet by welding manner.
The utility model by anti-explosion filaments shear knife is set, is used major diameter anti-explosion filaments still can work as capacitor core when breakdown by electric capacity when the large electric current of electric capacity demand, and anti-explosion filaments is more easily pulled off, and reaches good explosion-proof object.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is electric capacity partial schematic diagram;
Fig. 2 is anti-explosion filaments shear knife schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the electric capacity that has an explosion-proof shear knife comprises stem 1, unit of plastic 2, anti-explosion filaments (not shown), anti-explosion filaments shear knife 3, copper sheet 4.Stem 1 is arranged at capacitor top.Copper sheet 4 is arranged at the top of capacitor core and is connected with the positive pole of fuse; Unit of plastic 2 is arranged at the top of capacitor core, and is positioned at the top of copper sheet.Described unit of plastic 2 is for keeping apart fuse electrode and external electrode.
Described anti-explosion filaments shear knife is L shaped, and it comprises construction section 31 and acting section 32; Construction section 31 is connected by modes such as welding with acting section 32.In the middle of construction section, be provided with installing hole; Acting section 32 is provided with tool bore 32a and blade 32b.Described blade 32b flare, forms tool bore 32a between two blade 32b.Anti-explosion filaments one end is fixedly installed on stem lower end by welding manner, and the other end is through tool bore, and around along blade 32b around a circle, then through unit of plastic 2, stretching and be connected with the mode of copper sheet by welding.The diameter of described anti-explosion filaments is 1.0mm～2.5mm, and the demand of holding according to large-current electric is set the diameter of anti-explosion filaments.
When electric capacity does not have when breakdown, to keep in touch state between anti-explosion filaments and blade; When the fuse of electric capacity is breakdown, the inner HTHP that produces of electric capacity, electric capacity cap is heaved, because anti-explosion filaments is wound around blade, anti-explosion filaments is pulled out of shape, and heaves the power effect that cap increases anti-explosion filaments and blade, makes blade in anti-explosion filaments, cut out the responsive defect of the fractures such as breach, thereby anti-explosion filaments is broken, reached explosion-proof object preferably.
Electric capacity of the present utility model is by anti-explosion filaments shear knife is set, and uses major diameter anti-explosion filaments still can work as capacitor core when breakdown when the large electric current of electric capacity demand, and anti-explosion filaments is more easily pulled off, and reaches good explosion-proof object.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
