The day for announcing is that the granted patent ZL201020214022.5 on October 29th, 2010 discloses a kind of more lightening, encapsulation is more reliable, electric property is better, result of use is good metallic film capacitor.It comprises capacitor core, the lead-in wire that is connected with capacitor core, described capacitor core periphery is provided with the plastics shell, be provided with glue between described plastics shell and the capacitor core, described lead-in wire parallels with the capacitor core thickness direction, capacitor is horizontal layout during use, and the capacitor maximum ga(u)ge is less than 10 millimeters.The utility model is applicable to capacitor.This capacitor exists to go to exist in using electronic product equally to be installed and used firmly inadequately, and electrode lead-out part divides the electric current that can bear big inadequately, and also may exist circuit is caused bigger defect problems such as series resistance ESR influence.

The utility model content

The utility model is installed and used firm inadequately for the existing capacitor of solution sometimes exists electrode in electronic product uses, electrode lead-out part divides the electric current that can bear big inadequately, and also may exist circuit caused defective present situations such as bigger series resistance ESR influence and provide a kind of simple in structure, can improve electrode and install and use fastness, strengthen electrode lead-out part and divide the current value that can bear, reduce the lead capacitance device that circuit is caused bigger series resistance ESR influence.

The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: a kind of lead capacitance device, comprise capacitor case, the capacitor inner core, it is characterized in that: capacitor inner core two ends are provided with first pair of contact conductor and second pair of these two pairs of contact conductor of contact conductor, corresponding with capacitor inner core two ends a pair of 2～4 pairs of positive stop strips that are equipped with on inwall leave location notch on the capacitor case in the middle of every pair of positive stop strip.Adopt the capacitor of two pairs of electrode outlet lines, can improve the anti-function of current that capacitor lead wire can bear to a greater extent, the electric current that electronic circuit can be loaded on the capacitor is shared on two different electrode outlet lines at capacitor inner core two ends; Also make simultaneously the electrode pin of capacitor itself be welded on and have more reliable and more stable installation welding performance in electronic product or the electronic product, improved electrode and installed and used fastness in installation; And the reduction of double lead electrode capacitor causes bigger series resistance ESR influence to circuit, has improved the circuit working performance.

As preferably, described positive stop strip quantity adopts 3 pairs.Generally adopt the capacitor case of 3 pairs of positive stop strip structures, can guarantee mounting means needs substantially flexibly different size electrode for capacitors lead-out wire.Can certainly whether adopt the positive stop strip logarithm of other quantity according to the actual conditions decision, to increase the contact conductor number.

As preferably, described positive stop strip is provided with the hypotenuse section by the capacitor case open end, and the hypotenuse section of two positive stop strips is provided with in opposite directions, the inclined-plane of two sections hypotenuse sections be provided with in opposite directions and and stopper slot between form and fall trapezoidal stopper slot targeting port.Play spacing, installation guide effect to the electrode for capacitors lead-out wire.

As preferably, another adjacent with the subtend inwall on described capacitor case subtend inwall upper end surface is provided with the sinking recess.The sinking recess can play the effect outside the shell of not spilling into of monitoring epoxy amount in carrying out the epoxy packages process.

The beneficial effects of the utility model are: can improve the anti-function of current that capacitor lead wire can bear to a greater extent, the electric current that electronic circuit can be loaded on the capacitor is shared on two different electrode outlet lines at capacitor inner core two ends; Also make simultaneously the electrode pin of capacitor itself be welded on and have more reliable and more stable installation welding performance in electronic product or the electronic product, improved electrode and installed and used fastness in installation; And the reduction of double lead electrode capacitor causes bigger series resistance ESR influence to circuit, has improved the circuit working performance.
