Abstract
The utility model aims at providing a core installing and fixing insert for an aluminum electrolytic capacitor, which has simple structure and can ensure an ejection pin to be firmly fixed in a shell. The insert comprises the ejection pin and a base, wherein the lower end of the ejection pin is fixed at the central part of the base; the upper end of the ejection pin is inserted into a winding core inner hole of the core; the excircle of the base is adaptive to the inner diameter of the shell; and the base is embedded at the bottom of the shell. The ejection pin can be fixed with the base in a riveting way. The base can be the round structure or the spoke-shaped structure, and more than 3 spokes are needed. The embodiment of the utility model adopts four spokes in the cross shape.
Description
[technical field]
The utility model relates to a kind of electrolytic capacitor part, refers to that especially a kind of aluminium electrolytic capacitor kernel installs and fixes mold insert.
[background technology]
Aluminium electrolytic capacitor is made up of parts such as kernel, shell, leadout electrode, sealing gasket and cover plates.Kernel is made up of electrolysis aluminium foil, electrolytic paper and electrolyte parcel volume core, and one-body molded in the middle of the bottom in the shell have a thimble, and this thimble external diameter is suitable with volume in-core hole, and thimble inserts in the hole below the kernel volume core, and kernel is fixed.Thimble and shell are one-body molded generally speaking more easily realizes, as interior thimble structure, when the external fixation double-screw bolt was arranged again, it is very difficult that this inside and outside column structure is realized with forging and pressing machine-shaping, and the waste aluminum is puzzlement those skilled in the art's a difficult problem always.
[summary of the invention]
Kernel at the prior art aluminium electrolytic capacitor need adopt the fixing technical problem of thimble, the purpose of this utility model be to provide a kind of simple in structure, can make the kernel of thimble firm fixation in shell install and fix mold insert, this mold insert comprises thimble and base, the base centre is fixed in the thimble lower end, insert in the volume in-core hole of kernel the upper end, base circumcircle and internal diameter of outer cover are suitable, and the base insert is in outer casing bottom.
The beneficial effects of the utility model are: processing and forming is made separately, technology is simple, be used in combination with flat band screw column aluminium shell, substitute the inside and outside rod structure aluminium shell of unmanageable band, therefore broken through the machining upper limit technical bottleneck of the inside and outside rod structure aluminium shell of band; Can also be used with the conventional aluminium shell flexibly and substitute thimble aluminium shell in the band.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the mounting structure schematic diagram of the utility model in aluminium electrolytic capacitor.
Fig. 2 is the utility model vertical view.
Fig. 3 is the A-A cut-away view of Fig. 2.
Among the figure: 1 be kernel, 11 for the volume core, 2 for shell, 3 for leadout electrode, 4 for cover plate, 5 for fixing mold insert, 51 for thimble, 52 bases, 521 for spoke, 522 for strength bar, 6 for sealing gasket, 7 be the base circumcircle.
[embodiment]
Referring to accompanying drawing, electrolytic capacitor kernel of the present utility model installs and fixes mold insert and comprises thimble 51 and base 52, and base 52 centres are fixed in thimble 51 lower ends, and insert in volume core 11 endoporus of kernel 1 upper end, base 52 circumcircles 7 are suitable with shell 2 internal diameters, and insert is in shell 2 bottoms.
Described thimble 51 can adopt riveted joint with the fixing of base 52.Described base 52 can be circular configuration or spoke-like structure, and spoke quantity is more than at least 3, and embodiment of the present utility model adopts 4 spokes, across.At cross aluminium matter base 52 centre riveting dress thimbles 51, spoke 521 is provided with strength bar 522, in order to gain in strength, the base circumcircle 7 of cross 52 4 spokes of base is suitable with shell 2 internal diameters, it is not loosening just in time to withstand shell 2 sidewalls during insert, and thimble 51 diameters in the middle of riveting is contained in are slightly less than kernel volume core 11 diameters, make things convenient for insert to use.
