Description

A kind of laminated ceramic capacitor

Technical field

The present invention relates to electric fittings field, particularly relate to a kind of laminated ceramic capacitor.

Background technology

In recent years, along with the mobile apparatus such as portable phone universal, as the high speed of the semiconductor element of the critical piece of PC etc. and high frequency, for the multi-layer ceramic capacitor be equipped in this kind of electricity machine, in order to meet the characteristic as bypass capacitor, requirement that is small-sized, high capacity improves constantly.But there is following technical problem: existing ceramic capacitor volume is larger, improve capacitance and can cause the larger space taking electronic product, therefore increase capacitance when reducing device volume and become technological difficulties, and the load point of existing radio frequency electric capacity and earth point are arranged on fixing position, therefore by astronomical cycle to circuit board time, circuit board ad-hoc location can only be installed on, can not arrange flexibly.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of laminated ceramic capacitor, and it is reasonable in design, and structure is simple, solves problem structure connecting disappearance.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is to provide a kind of laminated ceramic capacitor, comprises internal electrode, ceramic layer body and outer electrode; Described ceramic layer body is composited by silica column by multi-layer ceramics elementary layer; Described internal electrode is sandwiched between adjacent ceramic unit layer; The described respective surfaces accompanying the ceramic unit floor of internal electrode is provided with the spill district agreed with described internal electrode shape; Described outer electrode is coated in the exterior lateral sides of described ceramic layer body; Described outer electrode is also connected with described internal electrode; Described outer electrode comprises base stage, resin bed and coating; Described outer electrode is provided with guide card protruding laterally; The edge of described outer electrode is also provided with a series of positioning area caved inward.

Preferably, between the ceramic unit layer that same layer is adjacent, an internal electrode is at least provided with; Described internal electrode is that nickel metal is made.

Preferably, the thickness of described ceramic unit layer is 1 ~ 2mm; Coating on described outer electrode is copper plate.

The invention has the beneficial effects as follows: a kind of laminated ceramic capacitor is provided, improves dielectric constant, and structure is frivolous, also enhance the concatenation ability on capacitor simultaneously, meet miniaturized and jumbo user demand.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of laminated ceramic capacitor of the present invention;

In accompanying drawing, the mark of each parts is as follows: 1, internal electrode; 2, ceramic layer body; 3, outer electrode; 4, base stage; 5, resin bed; 6, coating; 7, coating; 8, positioning area.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

Refer to accompanying drawing 1, the embodiment of the present invention comprises:

A kind of laminated ceramic capacitor, comprises internal electrode 1, ceramic layer body 2 and outer electrode 3; Described ceramic layer body 2 is composited by silica column by multi-layer ceramics elementary layer; This structure can dust-proofly insulate, and avoiding dust to enter affects arrangement works.Described internal electrode 3 is sandwiched between adjacent ceramic unit layer; The thickness of described ceramic unit layer 2 is 1 ~ 2mm, because too thick ceramic unit layer is unfavorable for distributing of heat.An internal electrode 1 is at least provided with between the ceramic unit layer that same layer is adjacent; Described internal electrode 1 is made for nickel metal; The described respective surfaces accompanying the ceramic unit floor of internal electrode 1 is provided with the spill district agreed with described internal electrode shape; Use specific position to fix internal electrode, the ability of heat radiation can not only be increased, but also can displacement be prevented.Described outer electrode 3 is coated in the exterior lateral sides of described ceramic layer body 2; Described outer electrode 3 is also connected with described internal electrode 1; Described outer electrode comprises base stage 4, resin bed 5 and coating 6; This coating 6 is copper plate.Described outer electrode 3 is provided with guide card 7 protruding laterally; Guide card can increase the external ability of structure, or carries out the effect of external stability.The edge of described outer electrode 4 is also provided with a series of positioning area 8 caved inward, positioning area 8 is used for carrying out location, outside or outside spacing, capital plays a role, and the position preventing capacitor from causing due to misoperation in mounting limit process is moved.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
