Abstract
The utility model provides a condenser and be provided with circuit board of this condenser, wherein, the condenser includes: capacitor body and setting are in last positive terminal and the negative pole end of capacitor body, the positive terminal with the negative pole end is connected with the pin of different quantity respectively. Because the utility model provides a positive terminal of condenser and the pin that the negative pole end was provided with different quantity, slow -witted effect is prevented to effectual playing.
Description
Technical field
The utility model relates to field of electronic devices, particularly relates to a kind of capacitor and is provided with the circuit board of this capacitor.
Background technology
At present, in design of electronic circuits, SMT (technology is pasted on surface) making technology is the main flow mode of production of current electronic product.As components and parts, SMD bulky capacitor is absolutely necessary in the design.But in SMT production process, electric capacity is beaten anti-situation and is happened occasionally.If during for production circuit board materials, if there is other electric capacity anti-loaded, in the processing procedure process that SMT is current, supplier is difficult to identify capacitor to beat anti-situation.Therefore, exist can effectively avoid by the needs making anti-capacitor.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly effectively can prevents the capacitor of the appearance of beating anti-phenomenon and be provided with the circuit board of this capacitor.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of capacitor, comprising: electric capacity body and the positive terminal be arranged on described electric capacity body and negative pole end, described positive terminal and described negative pole end are connected to the pin of varying number.
As preferably, described positive terminal is connected with 1 pin, and described negative pole end is connected with 2 pins.
As preferably, described capacitor is patch capacitor.
A kind of circuit board, comprise mainboard and be arranged on the capacitor on described mainboard, described mainboard corresponds to the positive terminal of same capacitor different with the quantity of the contact of negative pole end, and the quantity of contact corresponding to the described positive terminal of this capacitor is identical with the number of pins of the positive terminal of this capacitor, the quantity of contact corresponding to the described negative pole end of this capacitor is identical with the number of pins of the negative pole end of this capacitor, and when being multiple corresponding to the described positive terminal of same capacitor or the contact of negative pole end, the plurality of contact is electrically connected to each other.
As preferably, the contact described mainboard corresponding to the positive terminal of described capacitor is 1, and the contact corresponding to the negative pole end of described capacitor is 2.
As preferably, described circuit board is SMD circuit board, and described capacitor is SMD electric capacity.
Compared with prior art, the beneficial effects of the utility model are:
1, the positive terminal of capacitor provided by the utility model and negative pole end have the pin of varying number, thus effectively can tell positive pole and the negative pole of capacitor, and what prevent from occurring when making electricity container beats anti-situation, has the effect of fool proof;
2, circuit board provided by the utility model is provided with the contact corresponding to the positive terminal of capacitor and the pin of negative pole end, therefore, when producing circuit board, anti-situation is beaten if there is capacitor, there will be the situation that capacitor drops, thus further prevent capacitor on circuit board from beating instead.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, for the structure chart of a kind of capacitor of the utility model embodiment, comprising: electric capacity body 1 and the positive terminal 2 be arranged on electric capacity body 1 and negative pole end 3, and this positive terminal 2 and negative pole end 3 are connected to the pin of varying number, as shown in Figure 1, positive terminal 2 is connected with 1 pin, and negative pole end 3 is connected with 2 pins.By such configuration, be then easy to the positive and negative terminal telling electric capacity, can effectively avoid occurring beating anti-phenomenon when welding electric capacity on circuit boards or connect electric capacity.In addition, the capacitor in the present embodiment can be SMD electric capacity.
As shown in Figure 2, for a kind of circuit board of the utility model embodiment and the johning knot composition of capacitor, wherein, the capacitor that circuit board comprises mainboard 4 and is arranged on mainboard 4, the positive terminal 2 of capacitor and negative pole end 3 are connected to the pin of varying number, and the positive terminal 2 mainboard 4 corresponding to same capacitor is different with the quantity of the contact of negative pole end 3, and the quantity of contact corresponding to positive terminal 2 is identical with the number of pins of the positive terminal 2 of capacitor, identical with the number of pins of the negative pole end 3 of capacitor corresponding to the quantity of the contact of negative pole end 3, and the plurality of contact is electrically connected to each other when being multiple corresponding to the positive terminal of same capacitor or the contact of negative pole end, such as, on the mainboard 4 shown in Fig. 2, contact corresponding to negative pole end 3 is two, then these two contacts are electrically connected to each other.That is, no matter the quantity of the contact of corresponding same capacitor anode end/negative pole end is how many, these contacts final all link together, and why are provided with the corresponding contact of varying number, are the positions that positive terminal in order to distinguish capacitor and negative pole end should weld.
As shown in Figure 2, number of contacts mainboard 4 corresponding to capacitor anode end 2 is 1, number of contacts corresponding to capacitor anode end 3 is 2, when producing circuit board, when capacitor is beaten inverse time, electric capacity cannot firmly be welded on mainboard, can fall down from mainboard after then producing, therefore, by above-mentioned configuration can Timeliness coverage capacitor beat anti-situation, to adjust timely.
In addition, in the present embodiment, circuit board can be SMD circuit board, and accordingly, capacitor can be SMD electric capacity.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection range of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection range, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection range of the present utility model.
