In the figure, reference numeral 11 denotes a capacitor element formed by winding a plurality of metallized films formed by vapor deposition of metal film electrodes on the film, and reference numeral 12 denotes a metallikon provided on the end surface of the capacitor element 11. Further, 13 is a lead wire serving as a terminal for drawing out an electrode, 14 is solder, 15 is a resin case in which the capacitor element 11 is housed, 16 is a guide groove provided in the resin case 15 for preventing the lead wire 13 from being displaced. .

As a method of manufacturing the above conventional capacitor, as a method of attaching the lead wire 13 to the metallikon 12 of the capacitor element 11, it is general to attach the lead wire 13 by soldering. There is also a method of directly attaching the lead wire 13 to the metallikon 12 by resistance welding without using the solder 14 in FIG.

First, when the lead wire 13 is resistance-welded directly to the metallikon 12 of the capacitor element 11 with a small current, the attachment strength between the metallikon 12 and the lead wire 13 is likely to vary, which is more than the case of soldering. Therefore, the reliability of the welded portion of the metallikon 12 and the lead wire 13 is poor.

The end surface of the film of the capacitor element 11 which is in contact with is thermally deteriorated to deteriorate the capacitor characteristics.

Furthermore, the lead wire 13 by resistance welding
There is a method of using solder for the metallikon material itself in order to make the reliability of the welded portion of the same as that of soldering. In this method, the solder material is arc-sprayed on the end face of the capacitor element 11 to form the metallikon, but arc-spraying the solder material containing lead is environmentally harmful. Further, the unit price of solder is higher than that of a metallikon such as zinc whose material unit price is low, and when the solder metallikon is applied to the entire end surface of the capacitor element 11, the material cost becomes high and it becomes impossible to provide an inexpensive capacitor.

On the other hand, in the case of soldering, the lead wire 13
Since soldering is performed from above on the soldering iron, the lead wire mounting portion is as shown in FIG. In the case of a resin-filled dry metallized film capacitor in a resin case, which has become mainstream in recent years, particularly in a capacitor for mounting on a printed circuit board, a guide groove 16 is generally provided in a resin case 15 in order to obtain positional accuracy of the lead wire 13.

Is being positioned. However, in the capacitor to which the lead wire 13 is attached by soldering, the thickness, size, shape, etc. of the solder 14 are different, and as shown in FIG.
Since the lead wire 13 is not sufficiently housed in the guide groove 16 of the lead wire 13, the position of the lead wire 13 in the resin case 15 is easily displaced during the process after the lead wire 13 is attached such as resin filling and curing, and There was a problem that the position accuracy could not be obtained sufficiently.

FIG. 1 is a diagram showing the flow of the method for manufacturing the above-mentioned capacitor. As shown in FIG. 1, in this capacitor manufacturing method, in STEP 1, solder 4 is applied to a part of the metallikon 2 of the capacitor element 1, and in STEP 2, the lead wire 3 is arranged on the surface of the solder 4, STEP3
Attach an electrode for resistance welding to the lead wire 3,
It is welded by resistance welding. According to this method, since the solder 4 is arranged in advance between the metallikon 2 of the capacitor element 1 and the lead wire 3 and resistance welding is performed thereon, the position of the solder 4 melted at the time of resistance welding is used. Then, the solder 4 is solidified again, and the solder 4 does not exceed the wire diameter of the lead wire 3 and rises. By using such a manufacturing method, it is possible to obtain lead wire attachment strength equivalent to soldering as compared with the conventional method of resistance welding the lead wire 13 directly to the metallikon 12. In the present embodiment, the lead wire is arranged on the surface of the solder 4 and then the electrode for resistance welding is attached to the lead wire 3. However, the electrode attachment for resistance welding to the lead wire 3 is performed at this stage. However, the electrodes may be attached first, and then the lead wire 3 may be arranged on the solder surface portion.

FIG. 3 is a diagram showing the relationship between the tensile strength of the lead wire and the welding current value during welding in the capacitor of one embodiment of the present invention. As is clear from this figure, in this embodiment, the tensile strength (60
[N]), the welding current value flowing through the lead wire 3 to be welded should be 0.5 kA or more, and the welding current value of the conventional resistance welding should be 2.0 kA or more (not shown). The welding current value can be made smaller than that in (1).
Therefore, it is possible to prevent deterioration of the capacitor characteristics due to thermal deterioration of the end surface (film) of the capacitor element 1 that is in contact with the metallikon 2 during lead wire welding.

Further, FIG. 4 is a schematic cross-sectional view of the lead wire mounting portion when the welding current value during welding of the lead wire exceeds 1.5 kA in one embodiment of the present invention. Thus, the welding current value flowing through the welded lead wire 3 is 1.
If it exceeds 5 kA, the lead wire 3 is buried in the metallikon 2 of the capacitor element 1 and the lead wire 3 is not sufficiently housed in the guide groove 6 of the resin case 5 when it is inserted into the resin case 5, and the positioning accuracy of the lead wire deteriorates. Sometimes. Therefore, the welding current value flowing through the welded lead wire 3 is 1.5.

Needless to say, when the solder 4 is applied to the entire surface of the metallikon 2 of the capacitor element 1, the material cost becomes high, and resin is applied to the capacitor element 1 after the lead wire 3 is attached to the capacitor element 1. In a capacitor impregnated with an insulating oil, wax, or other impregnating agent, the impregnating ability of the impregnating agent is deteriorated due to the solder 4 covering the entire surface of the metallikon 2, and the effect of the impregnating agent for improving the characteristic of the capacitor is weakened and the capacitor characteristic deteriorates. To do. Therefore, it is desirable that the solder 4 is disposed on a part of the metallikon 2.

If the thickness of the solder 4 applied to a part of the metallikon 2 becomes thicker than the diameter of the lead wire 3 to be welded, the solder 4 rises over the lead wire 3 when the lead wire 3 is welded. In many cases, the same state as in soldering (similar to FIG. 8) is obtained, and the positional accuracy of the lead wire 3 may deteriorate. Therefore, it is desirable that the thickness of the solder 4 applied to a part of the metallikon 2 be equal to or smaller than the diameter of the lead wire 3 to be welded.
