Detailed description of the invention
Below in conjunction with the embodiment given by accompanying drawing, this utility model is described in further detail.
nullReferring to figs. 1 through shown in 3,A kind of Graphene ultracapacitor of the present embodiment,Including shell 1、The Graphene electrodes 2 being arranged in shell 1 and electrolyte,The described cylindrical setting of shell 1,Its one end is provided with the binding post 3 being connected with Graphene electrodes 2,Described binding post 3 includes the hollow insulation cylinder 31 through wiring board、The electric conductor 32 that is arranged in cylinder 31 and be arranged on electric conductor 32 and electric conductor 32 be pressed on circuit pads hold down assembly 33,One end of described cylinder 31 is fixedly connected with shell 1,Described electric conductor 32 is cylindrical graphene film,It is set in cylinder 31,One end is connected through shell 1 with Graphene electrodes 2,Sidewall is sticked on the inwall of cylinder 31,One end of described electric conductor 32 shell 1 dorsad maintains an equal level with one end of cylinder 31 shell 1 dorsad,One end of described electric conductor 32 shell 1 dorsad is additionally provided with the folding portion 321 of outwards turnover,Described folding portion 321 is cylindrical and is formed by an annulus folding,Its diameter is equal with electric conductor 32 diameter,Described holding down assembly 33 includes friction top 331 and the contraction spring 332 being set in electric conductor 32,Described cylinder 31 is provided with criss-cross fixed mount 311 towards one end of shell 1,The center of described fixed mount 311 is provided with fixing post 3111,Described contraction spring 332 is enclosed within fixing post 3111,And one end is fixed on fixed mount 311,The other end is fixedly connected with friction top 331,Described friction top 331 includes lid 3311 the most in the form of annular discs and cover rim 3312,Described lid 3311 is fixed on one end of cover rim 3312 electric conductor 32 dorsad,One end of described cover rim 3312 lid 3311 dorsad is fixedly connected with contraction spring 332,Described cover rim 3312 circle centre position offers through hole 4,Described lid 3311 is provided with threaded post 5 towards the center of circle of cover rim 3312 one end,Described fixing post 3111 offers screwed hole 6 towards one end of cover rim 3312,When capacitor is fixed on outside line plate,Threaded post 5 is threadeded through through hole 4 with screwed hole 6,Contraction spring 332 elongates,Folding portion 321 is launched in circular inconsistent with the pad of outside line plate,Folding portion 321 is compressed by cover rim 3312,Under Graphene ultracapacitor normal condition,Threaded post 5 is not connected to screwed hole 6,Lid 3311 separates with cover rim 3312,When needing the pad being fixed on wiring board by Graphene ultracapacitor,Have only to the folding portion 321 now folded is passed together with cover rim 3312 hole of pad on wiring board,Folding portion 321 is opened,So folding portion 321 becomes an annulus be attached on pad with regard to unfolded,Then by the through hole 4 along 3312 of threaded post 5 cover alignment on lid 3311,Threaded post 5 is threadeded through through hole 4 with screwed hole 6,The most here in through hole 4, also there is screw thread,When threaded post 5 passes through hole 4 when,Threaded post 5 and through hole 4 also have fixed relationship,And during fixing,First contraction spring 332 should be elongated cover rim 3312 pull-out,Then lid 3311 is fixed with cover rim 3312,Again threaded post 5 is threadeded with screwed hole 6,Owing in the present embodiment, the length of threaded post 5 is longer than contraction spring 332 length,So contraction spring 332 will hold cover rim 3312 after threaded post 5 is tightened,So just can be good at realizing the effect of a tension,Avoid the problem that threaded post 5 easily loosens,So just can be good at realizing an effect being tightly secured on wiring board by Graphene ultracapacitor,And do not have the firm not problem of loose contact.
