The utility model belongs to the electronic component technology field, and especially relates to a capacitor. The capacitor solves the technical problems in the prior art that the design is not reasonable enough, the heat radiation effect is poor, etc., and comprises a cylindrical metal shell and a winding core part arranged in the metal shell, wherein two lead pins which are arranged correspondingly and mutually and of which the end parts are both extended outside the metal shell, are arranged on the winding core part. The capacitor is characterized in that each lead pin comprises a first straight line segment connected with the winding core part and a second straight line segment connected with the first straight line segment, a spiral segment is arranged between the first and second straight line segments, and a flame retardant epoxy resin layer covering on the outside of the winding core part is arranged between the metal shell and the winding core part. Compared with the prior art, the advantages of the capacitor of the utility model are that the temperature of the capacitor can be reduced effectively, the heat radiation effect is good, and the service life of the capacitor is prolonged imperceptibly.
Description
Technical field
The utility model belongs to the electronic component technology field, especially relates to a kind of capacitor.
Background technology
Capacitor: the storage electric charge that the electrode that conductor approaching by two and mutually insulated is made forms and the device of electric energy are to do medium with the organic plastics film, with metal forming or metallized film, do electrode, by winding method, make.For useful life and the installation effectiveness that improves capacitor, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of structure [application number: 201020675552.X] of capacitor element, comprise element body, insulating cell and lead wire that pole plate, dielectric layer form, liner is in the internal layer of element body, common volume is flat cylinder, 2 lead wire are placed between liner and element body internal layer, at an end of element body, draw; Liner is the liner of flat ellipse at element center Formation cross-section.Two lead wire relatively, between be 2 layers of liner.Liner protrudes the element body end face at the end that element body is inserted with lead wire, effectively guarantees the insulation distance between lead wire.In addition, Chinese patent literature also discloses the structure of another kind of capacitor group, and [application number: 200620129459.2] comprises at least two capacitors that are positioned at same position on substrate, and this two capacitor is the first capacitor and the second capacitor.Wherein, the first capacitor comprises a plurality of the first capacitor cells that are connected in parallel to each other, and the second capacitor comprises a plurality of the second capacitor cells that are connected in parallel to each other, and the first capacitor cell and the second capacitor cell are staggered to an array.Above-mentioned two schemes has improved prior art to a certain extent, but has following defect: design unreasonablely, radiating effect is poor and useful life is short.
The utility model content
The purpose of this utility model is for the problems referred to above, and the capacitor of a kind of good heat dissipation effect and long service life is provided.
for achieving the above object, the utility model has adopted following technical proposal: this capacitor comprises tubular metal shell and is arranged on the interior coiling core of metal shell, be provided with two mutually corresponding arrange and end all extends to terminal pin outside metal shell on the coiling core, it is characterized in that, each described terminal pin comprises respectively the first straightway that is connected with the coiling core and the second straightway that is connected with the first straightway, be provided with spiral section between the first straightway and the second straightway, be provided with the fire retarding epoxide resin layer that is covered in coiling core outside between metal shell and coiling core.Obviously, the utility model design is more reasonable, and structure is simpler, and is practical, and in addition, it can reduce the temperature of capacitor effectively, and good heat dissipation effect, extended useful life virtually, meets the trend of current social technical development.
As preferably, in above-mentioned capacitor, described fire retarding epoxide resin layer thickness is 1.4mm.
As preferably, in above-mentioned capacitor, the spacing between described the first straightway is a times of spacing between the second straightway at least.
As preferably, in above-mentioned capacitor, described the first straightway, the second straightway and the spiral section formula that is connected as a single entity.
As preferably, in above-mentioned capacitor, described metal shell one end is provided with construction bolt.
Compared with prior art, the advantage of this capacitor is: it is more reasonable to design, and structure is simpler, practical, in addition, it can reduce the temperature of capacitor effectively, good heat dissipation effect, extended useful life virtually, meets the trend of current social technical development.
Description of drawings
