Abstract
The utility model relates to a capacitor explosion-proof aluminum shell. The capacitor explosion-proof aluminum shell comprises a body, wherein the body is of a cylindrical structure, the upper end of the body is open, the lower end is sealed, the bottom part of an inner cavity of the body is provided with three pressing marks which are of the shape of a Chinese character mi indicating rice, the pressing marks are located at the center of the bottom part of the body, an upper end opening of the body is provided with an outward folding edge, and the folding edge transits smoothly in an arc-shaped mode. The capacitor explosion-proof aluminum shell provided by the utility model has the advantages that by means of arranging three pressing marks which are of the shape of the Chinese character mi indicating rice on the bottom part of the inner cavity of the body, and the pressing marks are located at the center of the bottom part of the body, the pressing marks are exploded in explosion directly while a capacitor explodes because the pressing marks are vulnerable spots of stress, and the capacitor is exploded front the bottom part, thereby effectively preventing the periphery of the capacitor from being damaged, improving the safety performance, and saving a lot of resources and the maintenance cost.
Description
Technical field
The utility model relates to capacitor technology field, relates in particular to capacitor from explosion aluminum hull.
Background technology
Capacitor is commonly referred to electric capacity, and electric capacity is also called " capacitance ", refers to the electric charge reserves under given potential difference, is designated as C, and international unit is farad (F).In general, electric charge is understood stressed and is moved in electric field, has had medium between conductor, has hindered electric charge move and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is called electric capacity.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.
At present the making of capacitor case is short of to some extent aspect explosion-proof technology, when multiple electric capacity permutation and combination are together time, when after a capacitor blast, the damage of environmental capacitance device be can cause, waste maintenance cost and resource are difficult for the safety of other electric capacity to play guarantee.
Utility model content
In view of this, be necessary to provide a kind of capacitor from explosion shell of effectively avoiding causing because of capacitor blast the damage of environmental capacitance device.
The utility model is achieved in that capacitor from explosion aluminum hull, comprises body, described body is tubular structure, the upper end open of body, lower end sealing, the intracavity bottom of described body is provided with three impressions that are " rice " font, the centre of described impression in body bottom.
Further, described body upper end open place is provided with outside flanging, and described flanging arc is smooth excessively.
The advantage of the capacitor from explosion aluminum hull that the utility model provides is: by be provided with three impressions that are " rice " font at the intracavity bottom of body, and the centre of impression in body bottom, in capacitor blast simultaneously, because impression is stressed weak link, explosion time, directly pops impression, capacitor pops from bottom, effectively prevent that environmental capacitance device from receiving damage, improve security performance, and saved ample resources and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model capacitor from explosion aluminum hull.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the utility model capacitor from explosion aluminum hull.
Described capacitor from explosion aluminum hull, comprises body 10, and described body 10 is tubular structure, the upper end open 10a of body 10, lower end sealing, the intracavity bottom of described body 10 is provided with three impressions 20 that are " rice " font, the centre of described impression 20 in body 10 bottoms.
Described body 10 upper end open 10a places are provided with outside flanging 11, and described flanging 11 arcs are smooth excessively prevents the scuffing to staff, improves safety guarantee.
By be provided with three impressions 20 that are " rice " font at the intracavity bottom of body 10, and the centre of impression 20 in body 10 bottoms, in capacitor blast simultaneously, because impression 20 is stressed weak link, explosion time, directly pops impression 20, capacitor pops from bottom, effectively prevent that environmental capacitance device from receiving damage, improve security performance, and saved ample resources and maintenance cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
