Abstract
The utility model relates to a novel capacitor which comprises two bar-shaped metal pole plates, two layers of media and two connection terminals; the sides of the two bar-shaped metal pole plates are respectively connected with the two connection terminals, one layer of media is respectively arranged between the two metal pole plates connected with two connection terminals and at the outside of one of the metal pole plate, two layers of metal pole plate to be interlaced and the media are rolled up to form a column-shaped body, two connection terminals are protruded from one end of the column-shaped body, and a convex section is formed at the other end of the column-shaped body by rolling one of the metal pole plate, the convex sections are interconnected into a short circuit connection manner. The utility model provides a novel capacitor with simple fabrication process and low cost, which can effectively reduce the parasitic inductance.
Description
Technical field
The utility model relates to a kind of capacitor.
Background technology
Existing capacitor includes electrification container and noninductive capacitor.Wherein, the former mainly is rectangular and be connected with in advance at a side in the middle of the metal pole piece of terminal two, and one the outside respectively be provided with one deck medium, and make these interlaced two layers of pole pieces and medium curl into column, by the extremely last terminal shell that coats capacitor that promptly forms of the long two layer medium volume of length, two-terminal protrudes from the homonymy of column, constitutes the electrification container.Though this thoughts capacitor expense is cheap,, owing to the effect of stray inductance, there is the shortcoming of bad.The latter mainly is that two long-bar metal pole pieces and two layer medium is interlaced and curl into column, and at the two ends of this column, face down bonding to two metal pole pieces connects a metallic laminas respectively, with two metallic laminas of the corresponding connection of two terminals, constitutes noninductive electric capacity again.This noninductive capacitor, though practical, the shortcoming that exists is the manufacturing process trouble, and expense is higher.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes that a kind of manufacturing process is easy, expense is cheap, can effectively reduce the novel capacitor of stray inductance effect.
Realize the technical scheme of above-mentioned purpose: novel capacitor, comprise two strip metal pole pieces, two layer medium and two binding posts, the side of described two strip metal pole pieces connects two binding posts respectively, respectively establish one deck medium in two metal pole pieces that are connected with two binding posts outside middle and one of them metal pole piece, interlaced two layers of metal pole piece and medium curl into column, one end of column protrudes two binding posts, the other end of column has the protuberance of metal pole piece because of curling into of one of them, and protuberance is bonded with each other into short circuit and connects.
Adopt technique scheme, because when making, make one of them metal pole piece wideer than another metal pole piece and other medium, the end that interlaced two layers of metal pole piece and medium curl into behind the column capacitor protrudes two binding posts, the metal pole piece that the other end of column must have by broad protrudes the protuberance that forms, protuberance is bonded with each other into short circuit connects, thereby have the effect that reduces stray inductance, the capacitor quality has obtained effective raising.And entire making process is simple, ingenious, expense is cheap, with the advantage of electrification container and noninductive capacitor, is the extremely strong novel capacitor of a kind of practicality.
Description of drawings
Fig. 1 is a kind of deployed configuration schematic diagram of novel capacitor.
Fig. 2 is with the contour structures schematic diagram after the curling shaping of Fig. 1 novel capacitor.
Fig. 3 is the longitudinal sectional drawing that cuts along Fig. 2 binding post axis direction.
Embodiment
Embodiment: a kind of novel capacitor, comprise two long-bar metal pole pieces (1,4), two layer medium (3,7) and two binding posts (5,6), as shown in Figure 1, the side of long-bar metal pole piece 1 connects binding post 6, the side in the same way of long-bar metal pole piece 4 connects binding post 5, in the middle of metal pole piece (1,4), be provided with one deck medium 3, one deck medium 7 is respectively established in the outside at metal pole piece 2, the width of metal pole piece 1 goes out a distance L than another metal pole piece 4 and two layer medium (3,7) are wide, and promptly metal pole piece 1 has protuberance 2.Shown in Figure 2 is that interlaced two layers of metal pole piece (1,4) and medium (3,7) are curled into column, one end of column protrudes two binding posts (5,6), the other end of column by the metal pole piece 1 of broad because of curling into protuberance 2, protuberance 2 is bonded with each other into short circuit and connects, at this moment, column forms shell with the part of one deck medium 7.In Fig. 3, provided the profile that cuts along the axis direction of binding post shown in Figure 2 (5,6).
Present embodiment because by the metal pole piece of broad is set, through curling into protuberance, and is bonded with each other into short circuit with protuberance and connects, thereby have the effect that reduces stray inductance, and the capacitor quality has obtained effective raising.
