Abstract
The utility model discloses an aluminum electrolytic capacitor with improved safety, and the aluminum electrolytic capacitor comprises outer-layer electrolytic paper, a negative pole aluminum foil, insulating paper, inner-layer electrolytic paper and a positive pole aluminum foil which are sequentially connected from outside to inside, wherein the negative pole aluminum foil is provided with a negative pole guide pin and the positive pole aluminum foil is provided with a positive pole guide pin. The defect of undesirable short circuit sparking which occurs when the aluminum electrolytic capacitor encounters abnormal overload (overvoltage) is overcome, the safety of a product in end use is effectively ensured, the original maintenance cost is reduced, heavy losses such as a fire disaster caused by the original potential safety hazard are avoided, the stability of the product in use is ensured, and the aluminum electrolytic capacitor with improved safety has excellent practicability.
Description
Technical field
The utility model relates to the aluminum electrolytic capacitor technical field, concrete relates to a kind of aluminum electrolytic capacitor that improves fail safe.
Background technology
Existing aluminum electrolytic capacitor generally is applied in the equipment such as printer, facsimile machine, LCD, LCD TV; Wherein when overload (overvoltage) occurring when unusual; 30%～50% the short circuit and the situation of arcing can appear in conventional aluminum electrolytic capacitor in the line; Its result will cause pcb board periphery components and parts to damage, and severe patient maybe breaking out of fire, so be unfavorable for using safely and ensureing the stability in its use.
The utility model content
The purpose of the utility model is to solve the problem that exists in the prior art, and a kind of aluminum electrolytic capacitor that improves fail safe under the abnormal conditions of tackling is provided.
The utility model is achieved through following technical scheme:
A kind of aluminum electrolytic capacitor that improves fail safe comprises that ecto-entad connects the outer electrolytic paper of setting, negative pole aluminium foil, insulating paper, internal layer electrolytic paper and anodal aluminium foil successively.
Wherein, the negative pole aluminium foil is provided with the negative pole guide pin; Anodal aluminium foil is provided with anodal guide pin.
Simultaneously, the length of negative pole aluminium foil is longer than the length of anodal aluminium foil; The length of insulating paper is greater than the level interval between negative pole guide pin and the anodal guide pin.
Concrete, the negative pole guide pin is located at the inner surface of negative pole aluminium foil; Anodal guide pin is located at the inner surface of anodal aluminium foil.
In addition, be coated with electric gummed paper outside the outer electrolytic paper.
The usefulness of the utility model is:
The utility model has overcome aluminum electrolytic capacitor and has run into the be short-circuited when unusual bad phenomenon of arcing of overload (overvoltage); Effectively ensured the fail safe of product in use at the terminal; Reduced original maintenance cost; Avoid the heavy losses such as fire brought because of original potential safety hazard, ensured the stability that product uses, possessed preferable practicality.
Description of drawings
To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:
Fig. 1 is the molding structure sketch map of the utility model;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Be to comprise that ecto-entad connects the outer electrolytic paper 4 of setting, negative pole aluminium foil 2, insulating paper 3, internal layer electrolytic paper 5 and anodal aluminium foil 1 successively by a kind of aluminum electrolytic capacitor that improves fail safe of the utility model preferred embodiment like Fig. 1～shown in Figure 2.
Wherein, negative pole aluminium foil 2 is provided with negative pole guide pin 6; Anodal aluminium foil 1 is provided with anodal guide pin 7.
Simultaneously, the length of negative pole aluminium foil 2 is longer than the length of anodal aluminium foil 1; The length of insulating paper 3 is greater than the level interval between negative pole guide pin 6 and the anodal guide pin 7.
Concrete, negative pole guide pin 6 is located at the inner surface of negative pole aluminium foil 2; Anodal guide pin 7 is located at the inner surface of anodal aluminium foil 1.
In addition, outer electrolytic paper 4 outsides are coated with electric gummed paper 8.
Being illustrated in figure 2 as the disassembly diagram of each assembly of the utility model, is the end of reel with the left end with above-mentioned each assembly, and right-hand member is first for volume, and coiling promptly becomes a complete fuse clockwise.
In the actual production, the width of electric gummed paper 8 is enlarged to L-4mm max, (wherein L represents fuse length; Be the width of outer electrolytic paper 4); So that the fuse tightness increases, prevent inner heat when overload and cause thermal expansion, and then cause internal structure distortion displacement and cause the short circuit arcing; Again outer electrolytic paper 4 and internal layer electrolytic paper 5 are enclosed around three earlier in the roll set position; The dielectric strength of roll set position is increased, prevent when overload because of anodal aluminium foil 1 contacts short-circuit fire with negative pole aluminium foil 2, and then effectively improved the coefficient of safety of finished product.
