Abstract
The utility model provides an electrolytic capacitor, including metal casing, electric capacity core, anodal guide pin, negative pole guide pin, the electric capacity core is located the metal -back is internal, metal shells inner wall scribbles the insulating layer, electric capacity core surface with exist gappedly between the internal surface of metal -back, the electric capacity core respectively with anodal guide pin with the negative pole guide pin links to each other, anodal guide pin with the negative pole guide pin is followed stretch out metal casing one side, metal casing one side is equipped with jiao gai, jiao gai is equipped with the arch. The beneficial effects of the utility model are that: it is leading -in to guide the condenser to pinpoint when electrolytic capacitor installs, brings very big convenience for production, has improved work efficiency, simultaneously, can also the effectual removal that restricts electrolytic capacitor.
Description
Technical field
The utility model relates to capacitor technology field, particularly relates to electrolytic capacitor.
Background technology
Electrolytic capacitor is generally be made up of aluminum hull body, capacitor core and Jiao Gai.Wherein capacitor core is overlapped by anode metal paper tinsel, electrolytic paper, cathodic metal paper tinsel, electrolytic paper etc. 4 layers to reel, then form through the process of impregnation electrolyte.Because the capacitor core carrying out the process of impregnation electrolyte is likely because installation accuracy is not high, produces and crookedly encounter aluminum hull inwall, make aluminum hull cause capacitor core to be short-circuited phenomenon.So the electrolytic capacitor of prior art is when assembling around capacitor core and need have the space length of 1 ~ 3 millimeter between the inwall of aluminum hull according to withstand voltage situation.Along with the size of various electronic system (product), comprise day by day reducing of thickness, other electronic components can meet the requirement of this trend substantially, this also requires that electrolytic capacitor does not lose on the basis of previous level in its performance, overall dimension is miniaturized further, and the spacing distance therefore between above-mentioned electrolytic capacitor capacitor core and aluminum hull is the important restraining factors that capacitor littleization develops.
Utility model content
In order to solve the problems of the prior art, the utility model provides a kind of electrolytic capacitor.
The utility model provides a kind of electrolytic capacitor, comprise metal shell, capacitor core, positive pole guide pin, negative electrode guide needle, described capacitor core is positioned at described metal shell, described metal shell inwall scribbles insulating barrier, gap is had between described capacitor core outer surface and described metal shell inner surface, described capacitor core is connected with described negative electrode guide needle with described positive pole guide pin respectively, described positive pole guide pin and described negative electrode guide needle stretch out from described metal shell side, described metal shell side is provided with Jiao Gai, and described glue is covered with projection.
As further improvement of the utility model, between described capacitor core outer surface and described metal shell inner surface, be spaced apart 0.3mm.
As further improvement of the utility model, described height of projection is lower than described positive pole guide pin and described negative electrode guide needle.
As further improvement of the utility model, described projection is positioned at described positive pole guide pin side or described negative electrode guide needle side.
As further improvement of the utility model, the cylindrical shape of described projection.
As further improvement of the utility model, described metal shell is made up of aluminum.
The beneficial effects of the utility model are: capacitor can be guided when electrolytic capacitor is installed accurately to locate importing, bring great convenience, improve operating efficiency to production; Meanwhile, the movement of electrolytic capacitor can also effectively be limited.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of electrolytic capacitor, comprise metal shell 1, capacitor core 2, positive pole guide pin 3, negative electrode guide needle 4, described capacitor core 2 is positioned at described metal shell 1, described metal shell 1 inwall scribbles insulating barrier, gap is had between described capacitor core 2 outer surface and described metal shell 1 inner surface, described capacitor core 2 is connected with described negative electrode guide needle 4 with described positive pole guide pin 3 respectively, described positive pole guide pin 3 and described negative electrode guide needle 4 stretch out from described metal shell 1 side, described metal shell 1 side is provided with Jiao Gai, described glue is covered with protruding 5.
0.3mm is spaced apart between described capacitor core 2 outer surface and described metal shell 1 inner surface.
Described protruding 5 height are lower than described positive pole guide pin 3 and described negative electrode guide needle 4.
Described protruding 5 are positioned at described positive pole guide pin 3 side or described negative electrode guide needle 4 side.
Described protruding 5 cylindrical shapes.
Described metal shell 1 is made up of aluminum.
Even if its negative and positive the two poles of the earth short circuit also can not be made because insulating barrier makes metal shell 1 inwall contact with capacitor core 2, ensure that capacitor core 2 can reduce the spacing distance between metal shell 1 inwall, even can completely fill.Because increased capacitor core 2 is that it is peripheral, therefore increased electrode area proportion is just higher, and capacitance volume ratio is increased obviously.Experiment shows, if metal shell 1 external diameter is constant, with under same requirement of withstand voltage, in electrolytic capacitor, capacitor core 2 can expand to and make capacitance promote 50%.Therefore, compared with prior art the utility model can reduce the overall dimensions of electrolytic capacitor on the basis that maintenance function and performance do not lose previous level, has untied the restriction that the larger volume of existing electrolytic capacitor develops electronic product littleization.
Jiao Gai is by plant produced shaping standard product, and glue covers and is provided with protruding 5.During assembling, Jiao Gai is pressed in metal shell 1 together with capacitor core 2 according to polarity.When electrolytic capacitor is installed, manipulator can guide capacitor accurately to locate importing by fixed routine, brings great convenience, improve operating efficiency to production.
During work, during machine recognition, the projection 5 adopting glue to cover positions, the differentiation of positive pole guide pin 3 and negative electrode guide needle 4 is made conveniently to realize automation, capacitor can be guided when electrolytic capacitor is installed accurately to locate importing, bring great convenience to production, improve operating efficiency; Meanwhile, the movement of electrolytic capacitor can also effectively be limited.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
