Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below will the present invention be described in further detail by specific embodiment and relevant drawings.
Referring to Fig. 3, the embodiment for a kind of ceramic condenser of the present invention comprises: electric capacity matrix and the termination electrode that is covered in electric capacity matrix two ends; Described electric capacity matrix comprises the electroded potsherd 5 of multilayer; Described termination electrode comprises first termination electrode 1 and second termination electrode 2; Described electrode comprises first electrode 3 and second electrode 4; Described first electrode 3 extends to described second termination electrode, 2 directions from described first termination electrode 1, described second electrode 4 extends to described first termination electrode, 1 direction from described second termination electrode 2, and the described potsherd 5 that has described first electrode 3 is crisscross arranged with the described potsherd 5 that has described second electrode 4; Be provided with at least one at the avris of described electric capacity matrix and dodge district 8, dodge in the district 8 and be provided with described first electrode 3 or described second electrode 4 described.
Dodge district 8 because two class electrodes of embodiment of the invention electric capacity have only one of them to be located at, therefore, when in dodging the district crackle 6 taking place, first electrode 3 can not contact with second electrode 4, thereby has reduced the probability of the accident that is short-circuited.
In another embodiment of described ceramic condenser, in the described ceramic condenser outside, can be provided with connecting portion, described connecting portion is used for being connected with other device, described other device for example: circuit board or the like.Described connecting portion can be connected with other device by the mode of welding, perhaps is connected with other device by modes such as bolts.
After condenser welding is received on the circuit board, because circuit board material and the greatest differences of ceramic material on expansion rate, near the zone that causes the electric capacity matrix connecting portion, to exist stress to concentrate, when the stress in the zone that this stress is concentrated bears the limit above the ceramic condenser ceramic body, ceramic condenser is promptly chipping, and the zone that described stress is concentrated is called dodges district 8.The described district 8 that dodges is positioned near electric capacity matrix avris, the connecting portion, its shape size and termination electrode shape, and perhaps near scolder 7 positions the connecting portion are relevant.
As shown in Figure 3, distinguishing 8 with dodging of first termination electrode, 1 place is example, if first termination electrode 1 is "] " shape, when electric capacity welds with circuit board mutually by connecting portion, scolder 7 is attached to the outside of first termination electrode 1 near the part of circuit board, scolder 7 couples together at two end points of the position that first termination electrode 1 adheres to, and roughly forms a triangle on the electric capacity matrix.
Dodge district's shape size of 8 different according to the size of stress and welding position, and it is different, for example: the shape of dodging district 8 also can be not only a triangle, can also be trapezoidal or a rectangle or a circular part, in general, the area of dodging district's 8 coverings is big more, and the effect of prevention short circuit is just good more.
In embodiments of the present invention, the position of dodging district 8 is relevant with the position of connecting portion, will divide several situations to describe below:
(1) referring to Fig. 3 and Fig. 4, when having only one to dodge the district 8 the time, if dodge the side that district 8 is positioned at close first termination electrode 1, then: the extending end of second electrode 4 is positioned at dodges outside the district 8, first electrode 3 can extend to from first termination electrode 1 and dodge district 8, and, continue to extend to second termination electrode 2 through after dodging district 8; If dodge the side that district 8 is positioned at close second termination electrode 2, then: the extending end of first electrode 3 is positioned at dodges outside the district 8, and second electrode 4 can extend to from second termination electrode 2 and dodge district 8, and after process was dodged district 8, continuation was extended to first termination electrode 1.Be positioned at the part of dodging outside the district 8 at the capacitive-based body, first electrode 3 and second electrode 4 can extend to extreme length as far as possible, different as according to device package and rated voltage, the minimum distance that the extending end distance of electrode is dodged 8 borders, district or other end electrode can be 50 μ m or 60 μ m or 85 μ m or other size, in actual applications, also can be according to the needs of processing technology or ceramic condenser performance, strengthen or dwindle this distance.With the length of first electrode 3 and second electrode 4 extend to as far as possible extreme length can strengthen interelectrode over against area, thereby keep capacitor's capacity to greatest extent.
Referring to Fig. 3,8 be triangle to dodge the district, and a side that is positioned near first termination electrode 1 is example, are triangles owing to dodge district 8, and are positioned at the part of dodging outside the district 8 that first electrode 3 and second electrode 4 can extend to extreme length as far as possible at the capacitive-based body.Close along with second electrode 4 and electric capacity matrix bottom, its development length can successively decrease gradually, and the value of at every turn successively decreasing can be a constant value, as the 0.1mm that successively decreases at every turn; Also can be the value of a variation, as the 0.1mm that successively decreases for the first time, the 0.11mm that successively decreases for the second time, 0.09mm or the like for the third time successively decreases; Also can just successively decrease every several electrodes, as the 0.1mm that successively decreases for the first time, not successively decrease for the second time, its electrode length was consistent with the first time, and 0.1mm or the like for the third time successively decreases.
