Abstract
The utility model relates to an anti-explosive capacitor shell, which comprises a barrel-shaped shell. The top end of the shell is opened, an anti-explosive groove formed by stamping is arranged on the barrel wall of the shell, the anti-explosive groove is arranged on the circumference of the shell and close to the bottom of the shell, and the longitudinal central line of the anti-explosive groove is parallel to the axis of the shell. The anti-explosive capacitor shell has the advantages that the anti-explosive groove is arranged on the circumference, when a capacitor is fixed, the bottom of the capacitor shell can be connected with a configured device, the capacitor can work stably and cannot be damaged in vibration environment. In addition, when the capacitor shell is operated, the anti-explosive groove is cracked due to increment of internal pressure, and a core package in the capacitor cannot be blown out, thereby avoiding accidents. The spraying scope of electrolyte is only limited on the identical layer of elements of the capacitor, thereby greatly reducing affected range, and being simple and easy in cleaning and repairing work.
Description
Technical field
The utility model relates to a kind of capacitor casing, especially a kind of capacitor casing with explosion-proof performance.
Background technology
General traditional capacitor basically all adopts common aluminum enclosure, adopts the aluminium electrolyte capacitor of conventional aluminium housing still to be widely used in a lot of fields owing to its superior performance.But in use if moment is passed through big electric current, the conventional aluminium liquid electrolytic capacitor is easy to blast.For this reason, existing capacitor is shaped on explosion-proof groove in the bottom of aluminum enclosure usually, makes it become region of stress concentration; When the capacitor internal pressure increases, at first let explosion-proof groove cracking discharge (electrolyte) pressure, thereby reduced the spraying range of electrolyte.Yet explosion-proof groove is located at the bottom of aluminum enclosure; Ftracture as if explosion-proof groove during use; Core containing in the capacitor is prone to blow up out cause the accident, and the sprinkling of electrolyte also still can exert an influence to other capacitor and the electric elements of upper strata or lower floor, still old bigger spread area.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, has explosion-proof groove position the capacitor casing that reasonably has explosion-proof performance is set and provide a kind of.
The purpose of the utility model is accomplished through following technical scheme; It comprises the housing of a tubular; The top of described housing is uncovered, and the barrel of housing is provided with through the explosion-proof groove that is stamped to form, and this explosion-proof groove is located on the periphery of housing and near housing bottom.
As preferably, the longitudinal centre line of described explosion-proof groove and the parallel axes of housing.
As preferably, described housing is by aluminium material compression moulding.
The beneficial effect of the utility model is: explosion-proof groove is set on periphery, and capacitor can be connected its bottom on the equipment that is disposed fixedly the time, so just can stably be operated in the vibration environment and unlikely damage; In addition; During work if since internal pressure increase when making explosion-proof groove cracking; Core Bao Buhui in the capacitor blows up out, has avoided the accident generation, the spraying range of electrolyte also only be confined to this capacitor with one deck components and parts; This just makes that the scope that is involved reduces greatly, and the cleaning repair is also simply much easier naturally.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side-looking structural representation of the utility model.
Label in the accompanying drawing is respectively: 1, housing, 2, explosion-proof groove.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in accompanying drawing; The utility model comprises the housing 1 of a tubular; The top of described housing 1 is uncovered; The barrel of housing 1 is provided with through the explosion-proof groove 2 that is stamped to form, and this explosion-proof groove 2 is located on the periphery of housing 1 and near housing 1 bottom.Explosion-proof groove 2 externally shows it is rectangular groove (barrel of groove must not be damaged), and the width of explosion-proof groove 2, length and the degree of depth can be confirmed as required; Described housing 1 is by aluminium material compression moulding.
The parallel axes of the longitudinal centre line of described explosion-proof groove 2 and housing 1, or parallel with the bus of periphery.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
