Abstract
The invention discloses an explosion-proof capacitor. The explosion-proof capacitor comprises a housing. The housing comprises an outer housing, an inner housing and reinforcing ribs. The reinforcing ribs include circumferential reinforcing ribs and axial reinforcing ribs. The reinforcing ribs are provided with through holes. The reinforcing ribs are arranged between the inner housing and the outer housing. The top part of the housing is provided with a tapered housing neck. The tapered housing neck is composed of a housing flange, a tapered housing neck inner wall and a tapered housing neck outer wall. The tapered housing neck inner wall is in an inverted tunnel shape. The lower end of the tapered housing neck inner wall is connected with the inner housing of the housing. The lower end of the tapered housing neck outer wall is connected with the outer housing of the housing. The upper end of the tapered housing neck inner wall is connected with the inner diameter of the housing flange. The upper end of the tapered housing neck outer wall is connected with the outer diameter of the housing flange. The explosion-proof capacitor has the advantages that the two-layer housing is large in strength and high in toughness and is capable of effectively resisting the inner pressure of the capacitor; in addition, the capacitor is provided with the reinforcing ribs, and the reinforcing ribs are provided with the through holes, so that the strength of the housing of the capacitor is further increased, and the explosion condition is avoided in the working process of the capacitor.
Description
Technical field
The present invention relates to a kind of capacitor, particularly relate to a kind of noinductive capacitor.
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 in the electric field can be stressed and move, and between conductor, had medium, then hindering electric charge moves and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is then called electric capacity.Electric capacity is one of a large amount of electronic component used in electronic equipment, is widely used in every the aspect such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuit.
In prior art, after a long time use, inside is easy to produce heat energy capacitor, causes internal pressure to raise.When pressure is elevated to certain numerical value, be easy to cause the condenser breakdown even situation of capacitor explodes to occur.
Summary of the invention
The object of the invention is the problem solving capacitor explodes, a kind of noinductive capacitor is provided.
The technical solution used in the present invention is: a kind of noinductive capacitor, comprise housing, described housing comprises shell, inner casing and reinforcement, and described reinforcement comprises circumferential reinforcement and shaft orientation reinforcing rib, described reinforcement is provided with through hole, and described reinforcement is between inner casing and shell; The top of described housing is provided with closing in shell neck, closing in shell neck is made up of shell flange, closing in shell neck inwall and closing in shell neck outer wall, described closing in shell neck inwall is in falling infundibulate, closing in shell neck inwall lower end connects with the inner casing of housing, closing in shell neck outer wall lower end connects with the shell of housing, closing in shell neck inwall upper end connects with shell flange internal diameter, and closing in shell neck outer wall upper end connects with shell flange external diameter.
As a further improvement on the present invention, the shell of described housing is provided with attaching clamp.
Further improve as of the present invention, between described shell and inner casing, be provided with filler.
The beneficial effect that the present invention adopts is: the capacitor of this structure, its double Shell intensity is large, toughness is strong, can effectively resist capacitor internal pressure, the setting of through hole on capacitor reinforcement and reinforcement, improve the intensity of capacitor casing further, the situation of having blasted when having stopped capacitor work.
Accompanying drawing explanation
Fig. 1 is body diagram of the present invention.
Shown in figure: 1 shell, 2 inner casings, 3 through holes, 4 shaft orientation reinforcing ribs, 5 circumferential reinforcements, 6 lugs, 7 shell flanges, 8 closing in shell neck outer walls, 9 closing in shell neck inwalls.
Embodiment
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of noinductive capacitor, comprises housing, described housing comprises shell 1, inner casing 2 and reinforcement, described reinforcement comprises circumferential reinforcement 5 and shaft orientation reinforcing rib 4, and described reinforcement is provided with through hole 3, and described reinforcement is between inner casing 2 and shell 1; The top of described housing is provided with closing in shell neck, closing in shell neck is made up of shell flange 7, closing in shell neck inwall 9 and closing in shell neck outer wall 8, described closing in shell neck inwall 9 is in falling infundibulate, closing in shell neck inwall 9 lower end connects with the inner casing 2 of housing, closing in shell neck outer wall 8 lower end connects with the shell 1 of housing, closing in shell neck inwall 9 upper end connects with shell flange 7 internal diameter, and closing in shell neck outer wall 8 upper end connects with shell flange 7 external diameter.
Its housing of the noinductive capacitor of this structure is made up of shell 1 and inner casing 2 double Shell, is provided with reinforcement, effectively raises the intensity of housing between shell 1 and inner casing.Meanwhile, reinforcement is provided with through hole 6, further increases the toughness of reinforcement.
During capacitor explosion simultaneously, its usual explosion vent is all positioned at capacitor casing near top, therefore closing in shell neck is provided with at the top of housing, closing in shell neck is made up of shell flange 7, closing in shell neck inwall 9 and closing in shell neck outer wall 8, closing in shell neck adopts double-decker equally, coordinating closing in shell neck inwall 9 in falling infundibulate, strengthening capacitor top intensity, solve capacitor explosion problem.
The shell 1 of housing is provided with attaching clamp 6, to facilitate the fixing of the capacitor of this structure and to use.
In order to strengthen the explosion-proof effect of the capacitor of the application further, between shell 1 and inner casing 2, be filled with filler.
The capacitor of this structure, its double Shell intensity is large, toughness is strong, can effectively resist capacitor internal pressure, the setting of through hole on capacitor reinforcement and reinforcement, improve the intensity of capacitor casing further, the situation of having blasted when having stopped capacitor work.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
