Abstract
The utility model discloses a capacitor comprising a core rod and a metallized film that is wound around the core rod. The utility model is characterized in that the core rod comprises two or more metallic conduits with fine heat conducting property and an insulated cylinder is arranged between the two adjacent metallic conduits. When the utility model is under the state of power up, the metallic conduits can well emit the heat which is produced by the capacitor to prevent the gathering of heat so as to guarantee the service life of the capacitor and further augment the capacitance of the capacitor.
Description
Technical field
The utility model relates to a kind of capacitor, particularly a kind of large value capacitor that is applied to power electronic system.
Background technology
The plug of capacitor is made by the plastics of insulation at present, and is poor by the plug heat dispersion that these insulating material are made.The metallized film of capacitor can produce certain heat under "on" position, because the heat dispersion of plug is poor, therefore the heat of its generation can't in time distribute, thereby can cause gathering of heat, when acquiring a certain degree, the heat that gathers to cause the damage of capacitor, thereby can influence the useful life of capacitor, the capacitance that has also limited capacitor simultaneously can't further increase.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the capacitor of a kind of perfect heat-dissipating, long service life.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of capacitor comprises plug and is wrapped in metallized film on the plug, it is characterized in that described plug comprises the metal tube that has the good heat conductive performance more than two or two, is provided with insulating cylinder between adjacent two metal tubes.
Preferred embodiment a kind of as the utility model, described metal tube is provided with two.
As the improvement of the above-mentioned enforcement of the utility model, the inwall of metal tube axially is provided with bossed rib.
The beneficial effects of the utility model are: the plug of the utility model capacitor is made up of the insulating cylinder that has the metal tube of good heat conductive performance more than two or two and be arranged between adjacent two metal tubes, under "on" position, the heat that metal tube can produce capacitor in time distributes, preventing gathering of heat, thereby guarantee useful life of capacitor; Because the heat that metallized film produces can in time distribute, therefore can further increase the capacitance of capacitor; The inwall of metal tube axially is provided with bossed rib, is convenient to capacitor plug fixing in manufacture process like this.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 be Fig. 1 along A-A to cutaway view.
Embodiment
With reference to Fig. 1, Fig. 2, the disclosed a kind of capacitor of the utility model comprises plug 1 and is wrapped in metallized film 2 on the plug 1.Plug 1 comprises two metal tubes 3 with good heat conductive performance, is provided with insulating cylinder 4 between two metal tubes 3.Certainly, the metal tube that constitutes plug also can be arranged to be provided with insulating cylinder more than three or three between adjacent two metal tubes, when metal tube is set to three or three when above, the technique effect that it reached is the same when being set to two, is not described further at this.
Capacitor of the present utility model is under "on" position, and the heat that metal tube can be in time produces capacitor distributes, and preventing gathering of heat, thereby guarantees the useful life of capacitor; Because the heat that metallized film produces can in time distribute, therefore can further increase the capacitance of capacitor.
The inwall of metal tube 3 axially is provided with bossed rib 5, and capacitor can pass through rib 5 in manufacture process like this, reaching the fixing of plug, thereby is convenient to the manufacturing of capacitor.
The above only is preferred embodiment of the present utility model, can not limit protection range of the present utility model with it, so long as the equalization of doing according to protection range of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
