Deformed example 1
[0079] exist Figure 7 The shown lead frame 12 has the same configuration as the above-mentioned best mode, except that the number of cathode mounting portions 6 corresponding to the number of anode mounting portions 7b is provided. In addition, the same code|symbol is attached|subjected to the member which has the same function as the above-mentioned best mode. Specifically, the cathode attachment portion 6 has the same juxtaposition structure as the anode attachment portions 7a, 7b, and is arranged in parallel at predetermined intervals and in the same shape. For such a lead frame 12, as Figure 8 As shown, among the eight capacitor elements 30 , the upper four capacitor elements 30 are also electrically connected to one cathode mounting portion 6 similarly to the lower four capacitor elements 30 .
[0080] By employing such a structure, the anode and the cathode of the capacitor element 30 can be stably blocked when the capacitor element 30 is laminated and when the lead ...
Deformed example 2
[0083] like Figure 10 As shown, except that a notch 13a is provided between the anode mounting portions 7a, 7b of the lead frame 12, the configuration is the same as the above-mentioned best mode.
[0084] In such a lead frame 12, the laminated solid electrolytic capacitor can be fabricated by bending it upside down, in contrast to the above-mentioned best mode, so that the anode mounting part 7a and the anode mounting part 7b can pass through an extremely short (with the two The total thickness of the two anode mounting parts 7a, 7b is equal to the length) of the connecting part 9.
[0085] In addition, in the above configuration, although a gap is generated between one capacitor element 30 group and the cathode mounting portion 6, if Figure 11 and Figure 12 As shown, by interposing the conductive adhesive 14 between the gaps, the cathode mounting portion 6 and the cathode portion 30b adjacent to the cathode mounting portion 6 can be electrically connected.
Deformed example 3
[0087] like Figure 13 As shown, except that one more cathode mounting part 6 and anode mounting part 7b are provided in the lead frame (that is, three cathode mounting parts and anode mounting parts are provided three by three), the structure is the same as that of the above-mentioned modification 1.
[0088] Specific as Figure 14 As shown, one anode mounting part 7b is folded in the same direction as that of the first modification, and the other anode mounting part 7b is folded in a direction opposite to that of the first modification. According to such a configuration, more capacitor elements 30 can be mounted.
[0089] In addition, the continuous number of the three anode mounting parts 7a, 7b can be increased within the range allowed by the design as required, and can be 4 or 5. In this case, the bending direction is reversed sequentially.
[0090] (something else)
[0091] (1) In the above method, the notch 13 that is easy to bend the lead frame 12 is formed at the ...
