Abstract

Abstract A process is disclosed for the manufacture of solid electrolytic capacitors wherein sintered anode elements with their anode wires are attached to a clamping fixture. In a further step a notch is formed in the anode wires. After bending of the anode wires the anode input wires which are held in an additional fixture are welded on in overlapping fashion. The notch acts as a designed fracturing or breaking point for the final separation of the capacitor elements. It is expedient to design the anode input wires to have a section expanded to form a roof like shovel.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 117 words
A process for the manufacture of solid electrolytic capacitors in which sintered anode elements of the capacitors have anode wires connected thereto and the anode wires are connected with anode input wires mounted to a second holding fixture, comprising the steps of: providing the anode wires with a notch at a point intended as a break off point; providing a first holding fixture connected to outer ends of the anode wires; bending the anode wires at the notches by a predetermined angle by use of the first holding fixture; overlapping and welding ends of the anode input wires with the anode wires adjacent the notches; and breaking off outer portions of the anode wires at the notches.
Claim 2
Dependent Claim 117 words
A process for the manufacture of solid electrolytic capacitors in which sintered anode elements of the capacitors have anode wires connected thereto and the anode wires are connected with anode input wires mounted to a second holding fixture, comprising the steps of: providing the anode wires with a notch at a point intended as a break off point; providing a first holding fixture connected to outer ends of the anode wires; bending the anode wires at the notches by a predetermined angle by use of the first holding fixture; overlapping and welding ends of the anode input wires with the anode wires adjacent the notches; and breaking off outer portions of the anode wires at the notches.
Claim 3
Dependent Claim 28 words
A process in accordance with claim 1 including the step of providing the anode input wires with a roof like section formed as a shovel like end section.
Claim 4
Dependent Claim 26 words
A process in accordance with claim 1 including the step of joining the anode wires and the anode input wires with each other by roll welding.
Claim 5
Dependent Claim 25 words
A process in accordance with claim 1 including the step of breaking off the anode wires by moving the first holding fixture back and forth.
Claim 6
Dependent Claim 133 words
A process for the manufacture of solid electrolytic capacitor in which an anode element of the capacitor has an anode wire connected thereto which is to be connected to an anode input wire, comprising the steps of: providing the anode wire with a notch at a point intended as a break off point; providing a holding fixture connected to an outer end of the anode wire to be removed; bending the anode wire at the notch by a predetermined angle by use of the holding fixture; overlapping and welding an end of the anode input wire with a portion of the anode wire adjacent the notch between the notch and the anode element; and bending the outer end of the anode wire so as to break off the outer end at the notch.
Claim 7
Dependent Claim 133 words
A process for the manufacture of solid electrolytic capacitor in which an anode element of the capacitor has an anode wire connected thereto which is to be connected to an anode input wire, comprising the steps of: providing the anode wire with a notch at a point intended as a break off point; providing a holding fixture connected to an outer end of the anode wire to be removed; bending the anode wire at the notch by a predetermined angle by use of the holding fixture; overlapping and welding an end of the anode input wire with a portion of the anode wire adjacent the notch between the notch and the anode element; and bending the outer end of the anode wire so as to break off the outer end at the notch.
