Existing ceramic capacitor is that general two strip metal wire adopts artificial plug-in unit or carries out the production of downstream product in the mode of artificial rear weldering operation, its automaticity is low, except needs are artificial by capacitor grafting or be soldered on circuit board in a large number, cause outside spent man-hour and cost significantly improve, also need to ensure suitable accuracy when artificial plug-in unit, otherwise just can plain conductor be caused easily to be subject to improper extruding because of the difficulty in assembling and be out of shape or fracture, not only integral production efficiency be low, locating effect is also inaccurate; In addition, the height of capacitor also cannot effectively be reduced, and have impact on the effect structure of finished product.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the reinforced laminated ceramic capacitor that a kind of structure is simple, easy for installation, have self-protection function.
To achieve these goals, the utility model adopts following technical scheme:
A kind of reinforced laminated ceramic capacitor, it comprises ceramic main body, be coated on external electrode on the end face of ceramic main body and some layers is arranged at interior electrode in ceramic main body, and described interior electrode intersecting distribution is also electrically connected with corresponding external electrode respectively; It also comprises the insulating barrier being coated on ceramic main body and external electrode outside, described insulating barrier is offered the conductive through hole being equipped with and being connected with external electrode.
Preferably, described ceramic main body comprises the dielectric layer covering skin and be arranged in covering skin, and described dielectric layer is distributed between adjacent two-layer interior electrode; Described covering skin is calcined shaping by barium titanate.
Preferably, the thickness of described interior electrode is 0.2-1.0 μm, and the thickness of described dielectric layer is 0.1-10 μm.
Preferably, described interior electrode is monel or Ni-Pd alloy.
Preferably, on described external electrode, be provided with corresponding to the position of conductive through hole and draw end pin outward.
Owing to have employed such scheme, the utility model is when assembling, can whole capacitor be embedded in circuit board, the electrical end pin of circuit board is connected with external electrode by conductive through hole, it is not only conducive to the steadiness strengthening capacitor installation, also insulating barrier can be utilized simultaneously to carry out perimeter defense (namely forming a cushion) to capacitor body, prevent because the extruding of circuit board or the applying of other external force cause capacitor to damage or breakage; Its structure is simple, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the reinforced laminated ceramic capacitor of the present embodiment, it comprises hexahedral ceramic main body 10, be coated on external electrode 20 on the end face of ceramic main body 10 and some layers is arranged at interior electrode 30 in ceramic main body 10; Wherein, interior electrode 30 intersecting distributes and is electrically connected with corresponding external electrode 20 respectively; It also comprises the insulating barrier 40 being coated on ceramic main body 10 and external electrode 20 outside, insulating barrier 40 is offered the conductive through hole (not shown) being equipped with and being connected with external electrode 20.So, when carrying out capacitor assembling, can whole capacitor be embedded in circuit board a, the electrical end pin of circuit board a is connected with external electrode 20 by conductive through hole, it is not only conducive to the steadiness strengthening capacitor installation, also insulating barrier 40 pairs of capacitor bodies can be utilized simultaneously to carry out perimeter defense (namely forming a cushion), prevent because the extruding of circuit board a or the applying of other external force cause capacitor to damage or breakage.
For improving the performance of capacitor itself, improve capacitor arrangement solidity, the ceramic main body 10 of the present embodiment comprises covering outer 11 and is arranged at the dielectric layer 12 covered in outer 11, and dielectric layer 12 is distributed between adjacent two-layer interior electrode 30; Covering skin 11 is then calcined shaping by barium titanate.
Further, for ease of the manufacture of capacitor, the thickness of the interior electrode 30 of the present embodiment is 0.2-1.0 μm, and the thickness of dielectric layer 12 is 0.1-10 μm.And interior electrode 30 preferably monel or Ni-Pd alloy.
For improving the convenience of the assembling of capacitor further, being provided with on external electrode 20, corresponding to the position of conductive through hole and drawing end pin 21 outward, utilizing the outer end pin 21 that draws to be connected with the electrical end pin of circuit board a with this.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content 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 utility model.
