Abstract
The utility model discloses an internal improved structure of a non-solid electrolyte tantalum electrolytic capacitor, and belongs to a non-solid electrolyte tantalum electrolytic capacitor. An objective is to provide a non-solid electrolyte tantalum electrolytic capacitor which can sustain high frequency vibration. The internal improved structure comprises a tantalum block with an embedded tantalum wire, and a plunger piston disposed on the top of the tantalum block and sleeved on the tantalum wire. The plunger piston is formed by an upper plunger piston (2) and a lower plunger piston (3) which are sleeved on the tantalum wire (1). A bottom surface of the upper plunger piston (2) is provided with a cylindrical pit, and side surfaces are provided with cylindrical structures with circular grooves. A low-half section of the lower plunger piston (3) is in a cone structure, and a top-half section is a cylindrical structure matched with the cylindrical pit. The top of the tantalum block (4) is provided with a cone pit matched with the cone. The internal improved structure can effectively reduce stress loaded on the tantalum wire, the stress being caused by shake of the plunger piston, and shock resistance capacity of the capacitor is improved. The structure is an improvement of the non-solid electrolyte tantalum electrolytic capacitor.
Description
Technical field
The utility model relates to a kind of non-solid electrolyte tantalum electrolytic capacitor, relates in particular to a kind of non-solid electrolyte tantalum electrolytic capacitor internal modifications structure.
Background technology
At present, the internal structure of non-solid tantalum electrolytic capacitor from bottom, be up lower gasket, tantalum piece, Upper gasket (partition capacitance device does not have Upper gasket) successively, with stick harness, the insulator of O shape circle.Although this structure is simple, when being subject to vibrating, the pad or the stick harness that are enclosed within on tantalum wire easily rock, thereby cause the oxide-film of tantalum wire root because of stressed excessive impaired damage, finally cause properties of product deteriorated, therefore should not under the environment of high vibration level, work.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide a kind of non-solid electrolyte tantalum electrolytic capacitor internal modifications structure that can bear dither.
To achieve these goals, the utility model by the following technical solutions: it comprises that top is inlaid with the tantalum piece of tantalum wire, is positioned at this tantalum piece top and is enclosed within the plunger on described tantalum wire; Described plunger consists of the upper plug and the lower plunger that are enclosed within on tantalum wire, wherein, upper plug is that bottom surface has cylindrical pit, side to have the cylindrical structure of cannelure, and the lower semisection of lower plunger is that conical structure, upper semisection are the cylindrical structures suitable with described cylindrical pit; The conic shaped suitable with described cone arranged at the top of tantalum piece.
Compared with the prior art, the utility model is owing to having adopted technique scheme, in the lower surface of traditional cylinder plunger, increased a lower plunger that is conical structure, and at the top of tantalum piece, be provided with one with the suitable conic shaped of the cone part of lower plunger; Therefore can effectively weaken because plunger rocks the stress loading on tantalum wire, so protected tantalum wire root oxide-film, improved the vibration resistance of capacitor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: tantalum wire 1, upper plug 2, lower plunger 3, tantalum piece 4.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: the tantalum wire 1 that is embedded in tantalum piece 4 protrudes upward from the top of this tantalum piece, and conical pit is arranged at the top of tantalum piece 4, on tantalum wire 1, cover has lower plunger 3 and upper plug 2; The lower semisection of lower plunger 3 is that the conical structure suitable with described pit, the upper semisection of this lower plunger are cylindrical structure, upper plug 2 is cylindrical structure, and this upper plug bottom surface has the cylindrical pit suitable with the upper semisection of lower plunger 3, the side of this upper plug to be provided with cannelure.
Claims (1)
1. a non-solid electrolyte tantalum electrolytic capacitor internal modifications structure, comprises that top is inlaid with the tantalum piece of tantalum wire, is positioned at this tantalum piece top and is enclosed within the plunger on described tantalum wire; It is characterized in that: described plunger consists of the upper plug (2) and the lower plunger (3) that are enclosed within on tantalum wire (1), wherein, upper plug (2) for there are cylindrical pit, side in bottom surface, have the cylindrical structure of cannelure, the lower semisection of lower plunger (3) is that conical structure, upper semisection are the cylindrical structures suitable with described cylindrical pit; The conic shaped suitable with described cone arranged at the top of tantalum piece (4).
