Description

Four ends are drawn metallic film capacitor

(1), technical field: the utility model relates to a kind of capacitor, particularly relates to a kind of four ends and draws metallic film capacitor.

(2), background technology: the two ends of metallic film capacitor will spray metal level, and metal level covers the end face of whole capacitor device, so that the extraction electrode pin, electrode pin is welded on the metal level.It is two electrode pins of burn-oning on each end metal level of capacitance body that four general ends are drawn electric capacity, then encapsulation.The four end electric capacity that make like this meet the requirement of four exits in appearance, but two electrode pins of each end of capacitor are directly to be connected with the electrode of capacitor inside by metal level, be that these two electrode pins are connected with the same point of the same electrode of capacitor inside, this is not four end electric capacity truly, the electric property of this four end electric capacity far can not reach user's requirement, and, because two electrode pins are welded on the same metal level, if have an electrode pin to go wrong (burning), can have influence on another root electrode pin as electrode pin.

(3), utility model content:

The technical problems to be solved in the utility model is: at the prior art deficiency, provide a kind of good electric property, four ends simple in structure to draw metallic film capacitor.

The technical solution of the utility model:

A kind of four ends are drawn metallic film capacitor, contain capacitance body, the two ends of capacitance body are coated with the metal level body, the metal level body at capacitance body two ends is connected with two electrodes of capacitance body inside respectively, be welded with two electrode pins on the metal level body of each end of capacitance body, the metal level body of each end of capacitance body contains two branch metal level bodies that are set up in parallel and are separated from each other, two branch metal level bodies are connected with the diverse location of the same electrode of capacitance body inside, and two electrode pins are welded on respectively on two branch metal level bodies.

Two branch metal level bodies cover the both sides of an end face of capacitance body respectively, two branch metal level body certain distances spaced intermediate.

Capacitance body is cylindrical, or is oblate cylindricality, or is square column type.

The beneficial effects of the utility model:

1, the metal level body of each end of capacitance body of the present utility model contains two branch metal level bodies that are set up in parallel and are separated from each other, two branch metal level bodies are connected with the diverse location of the same electrode of capacitance body inside, two electrode pins are welded on respectively on two branch metal level bodies, like this, two electrode pins are connected with the difference of the same electrode of capacitor inside respectively, have guaranteed the electric property of capacitor.And, because two electrode pins are welded on two branch metal level bodies,, can not have influence on another root electrode pin if there is an electrode pin to go wrong yet.

2, the utility model when making, only need the metal level body of each end face of capacitor in separated getting final product, therefore, it is simple in structure, cost of manufacture is low.

Fig. 1 is the structural representation that four ends are drawn metallic film capacitor;

Fig. 2 is the plan structure schematic diagram of Fig. 1

Fig. 3 is the right TV structure schematic diagram of Fig. 1.

(5), embodiment:

Referring to Fig. 1～Fig. 3, among the figure, four ends are drawn metallic film capacitor and are contained capacitance body 1, the two ends of capacitance body 1 are coated with the metal level body, the metal level body at capacitance body 1 two ends is connected with two electrodes of capacitance body 1 inside respectively, be welded with two electrode pins 4 on the metal level body of capacitance body 1 each end, 5, the metal level body of capacitance body 1 each end contains two branch metal level bodies 2 that are set up in parallel and are separated from each other, 3, two branch

metal level bodies

2,3 are connected two electrode pins 4 with the diverse location of the same electrode of capacitance body 1 inside, 5 are welded on two branch metal level bodies 2 respectively, on 3.

Two branch

metal level bodies

2,3 cover the both sides of 1 one end faces of capacitance body respectively, two branch

metal level body

2,3 certain distances spaced intermediate.If distance is 5mm between two

electrode pins

4,5 of capacitance body 1, then this distance that separates is 2mm, and along with the increasing of distance between the

electrode pin

4,5 can suitably increase the distance that this separates, but maximum is no more than 5mm.This distance that separates is generally 2 mm-5mm.

Capacitance body 1 is oblate cylindricality.
