Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1 ~ 2, a kind of novel capacitor, comprise housing 5, the upper end of this housing 5 is provided with the right pin 4 of first left pin 2, second left pin the 1, first right pin 3, second of separate insulation setting; The inside of housing 5 is provided with in vertical hollow core rod 8, and this plug 8 adopts the insulating material preparations such as plastics, this plug 8 is wound with the first metallized film 6; This first left pin 2 is electrically connected to by line the upper end of this first metallized film 6, this second left pin 1 to be electrically connected to this first metallized film 6 lower end by the line passed in this plug 8, namely this first metallized film 6 and the left pin 1 of the first left pin 2, second that is connected electrically define first independently electric capacity, are set as left electric capacity.Meanwhile, the outside of this first metallized film 6 is wound with insulation material layer 7; The outside of this insulation material layer 7 is wound with the second metallized film 9, and this first right pin 3 is electrically connected to by line the upper end of this second metallized film 9, this second right pin 4 to be electrically connected to this second metallized film 9 lower end by the line passed in this plug 8; Namely this second metallized film 9 and the right pin 4 of the first right pin 3, second that is connected electrically define second independently electric capacity, are set as right electric capacity.Like this, by the different modes of connection of the right pin 4 of first left pin 2, second left pin the 1, first right pin 3, second, can realize parallel connection and the series connection of left electric capacity and right electric capacity, this Combined electric capacity can obtain 4 kinds of different capacitances; Described first metallized film 6 is identical with the structure of the second metallized film 9, comprise: the coat of metal 91 and the plastic film top layer 92 and the plastic film bottom 93 that lay respectively at coat of metal two sides, the described coat of metal 91 material is zinc or aluminium, and described plastic film top layer 92 and plastic film bottom 93 material are polyolefin; Described plastic film top layer 92 has the contact bottom surface 921 contacted with the described coat of metal 91, described plastic film bottom 93 has the contact end face 931 contacted with the described coat of metal 91, and described contact bottom surface 921 has identical surface charge density with the described end face 931 that contacts; Described plastic film bottom 3 material is poly-third hydrocarbon.
