極に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lead wire welding electrode for series spot welding a lead wire to an object to be welded such as a capacitor element.
従来例の構成とその問題点
以下、従来例の構成について図面の第１図、第

部を被溶接物４に溶接するものである。 Next, the operation of the conventional example will be explained. A lead wire 3 having a spiral portion 3a formed at its tip has a lead wire passage groove 5 and a pair of electrodes 1 and 2 facing each other.
It is placed between. The pair of electrodes 1 and 2 facing each other presses the spiral portion 3a of the lead wire 3 against the workpiece 4 by a pressurizing means (not shown),
Electricity is applied through the electrode 1 to weld the spiral portion of the lead wire 3 to the workpiece 4.

に溶接する位置が狂いやすい欠点があつた。 However, since the welding method in the conventional example is series spot welding, if the lead wire passage groove 5 is made small, the current flows from one electrode 1 through the lead wire 3 to the other electrode 2. Another disadvantage is that the reactive current that does not contribute to welding increases, resulting in poor welding. Furthermore, if the diameter of the lead wire passing groove 5 is increased, it is possible to reduce the reactive current that does not contribute to welding, but the lead wire 3 can be
The disadvantage was that the welding position was easily misaligned.

This will be explained along with FIGS. Reference numerals 1, 2, and 5 are electrodes, electrodes, and lead wire passage grooves similar to the conventional one.
Insulating layers 6 and 7 are formed by coating Teflon or ceramic on the opposing surfaces of the electrodes 1 and 2 and on the lead wire passage groove 5, respectively, by baking or vapor deposition. The method of welding the lead wire to the object to be welded using the electrodes 1 and 2 is the same as the conventional method. The insulating layers 6 and 7 allow the diameter of the lead wire passage groove 5 to be made smaller than in the prior art, eliminate reactive currents that do not contribute to welding, and improve welding position accuracy.
