Abstract

The utility model discloses a shockproof aluminum electrolytic capacitor with novel electrode pin lines, which comprises a closed capacitor body formed by closing a core leached in electrolyte via an aluminum shell and a rubber cap. An anode pin and a cathode pin are arranged on the front end face of the aluminum shell. The shockproof aluminum electrolytic capacitor is structurally characterized in that an aluminum shell jacket is disposed outside the aluminum shell, the front end face of the aluminum shell is connected with the inner surface of the aluminum shell jacket through an elastic part, the inner lateral face of the aluminum shell jacket is fixedly connected with the outer lateral face of the aluminum shell through elastic parts, the anode pin and the cathode pin are led out of the aluminum shell jacket, and support pins adjacent to the anode pin and the cathode pin are arranged on the front end face of the aluminum shell jacket. The support pins share stress of the anode pin and the cathode pin in a vibrating environment so that the anode pin and the cathode pin are not easy to break, the aluminum shell jacket is prevented from vibrating to cause vibration of the aluminum shell by the aid the elastic parts and the vibration absorption effect is fine. Further, pin lines of the anode pin and the cathode pin are made of iron cores wrapped by copper layers, so that production cost is low and high frequency performance is promoted effectively.

Description

The antidetonation formula aluminium electrolytic capacitor of band novel electrode lead-foot-line

Technical field:

The utility model relates to a kind of aluminium electrolytic capacitor, especially belong to a kind of can be at the antidetonation formula aluminium electrolytic capacitor of the band novel electrode lead-foot-line of operate as normal under the vibration environment.

Background technology:

Use at present the aluminium electrolytic capacitor on the vibratory equipments such as being installed in engine, promptly aluminium electrolytic capacitor is fixed by the negative electrode pin of aluminium electrolytic capacitor and anode pin being welded on the circuit board such as the said equipment.But be under the vibrational state during owing to the said equipment work, and the volume of aluminium electrolytic capacitor own is big, own wt is heavier, therefore the generation pin breakage forms open-circuit condition and loses proper function easily.Existing aluminium electrolytic capacitor negative electrode pin and anode pin are generally the zinc-plated form of copper core, its production cost height.

Summary of the invention:

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the antidetonation formula aluminium electrolytic capacitor of cost band novel electrode low and that can better use under vibrational state lead-foot-line.

The purpose of this utility model is to realize like this, the antidetonation formula aluminium electrolytic capacitor of described band novel electrode lead-foot-line, comprise by covering the airtight capacitor body that constitutes with aluminum hull and glue behind the fuse impregnation electrolyte, anode pin and negative electrode pin are arranged on the front end face of described aluminum hull, its design feature is for to be outside equipped with the aluminum hull cover at aluminum hull, is connected by elastomer between the inner face of the front end face of aluminum hull and aluminum hull cover, between the lateral surface of medial surface that aluminum hull overlaps and aluminum hull, fixedlys connected by elastomer; Anode pin and negative electrode pin are drawn outside the aluminum hull cover, are provided with supporting pins with anode pin and the adjacent arrangement of negative electrode pin at the front end face of aluminum hull cover.

The purpose of this utility model also can be achieved through the following technical solutions, the antidetonation formula aluminium electrolytic capacitor of described band novel electrode lead-foot-line, its characteristics are that the lead-foot-line of described negative electrode pin and the lead-foot-line of anode pin adopt the outer iron core that is surrounded by the copper-clad layer, described copper-clad layer is provided with silver-plated or tin coating outward, and the thickness of described copper-clad layer is 0.02～0.25mm.

Advantage of the present utility model: the utility model is owing to be provided with an aluminum hull cover in the aluminum hull outside, the front end face of aluminum hull is connected by an elastomer with the inner face of aluminum hull cover, between the lateral surface of the medial surface of aluminum hull cover and aluminum hull, also can fixedly connected by elastomer, putting at aluminum hull has increased the supporting pins that is used for fixing capacitor, the aluminum hull cover has been shared the stressing conditions of negative electrode pin and anode pin in vibration environment, make it be not easy fracture, elastomer has been avoided the vibration of aluminum hull cover and has been caused the vibration of aluminum hull, and shockproof effect is better.And the lead-foot-line of negative electrode pin and anode pin is to adopt the outer copper-clad layer of iron core, and production cost is low, and can effectively improve high frequency performance.
