液３０に接続されている。(Prior Art) As a conventional method of chemically converting a lead wire terminal, as shown in FIG. 5, a lead wire terminal having a flat aluminum portion 21 has holes 23 into which a large number of lead wires 22 can be inserted. Some use a holder 24. When the lead wire 22 is inserted into the hole 23 of this holder 24, the welded part 25 of the lead wire terminal has a larger diameter than the hole 23, so the lead wire 22
2 stops at the welded portion 25, and the tips of the flat portions 21 of the lead wire terminals inserted in the same manner thereafter are almost aligned. Then, the inserted lead wire 22 is pressed by the hollowed-out vertical holding surface 26 of the holder 24 with a holding jig 27 equipped with a conductive brush. This presser jig 27 is connected to the power source 2
8, and the cathode is connected to the chemical conversion liquid 30 in the chemical conversion tank 29.

業できず、かつ作業性が悪い問題点を有していた。However, when using such a chemical conversion method,
Because the conductive part of the holding jig 27 that presses the lead wire 22 is a conductive brush, contact may be incomplete, or when a large number of wires are pressed by the holding jig 27, an imbalance may occur in which the lead wires are not pressed sufficiently. 22 may fall off, it is not possible to work in large quantities, and the workability is poor.

A lead wire terminal consisting of a wire and a welded lead wire 4 is inserted so that the lead wire 4 contacts the inner bottom surface of the container 1. A magnetic electrode jig 5 is disposed on the outer bottom surface of the container 1 containing the lead wire terminals in this manner, and the electrode jig 5 is connected to the anode of a power source 6. In this state, the lead wire 4 is attracted and held by the magnetism of the electrode jig 5, and does not fall off even if it is turned upside down.Since the tip of the lead wire 4 is in contact with the inner bottom surface of the container 1, the flat part 3 is also held at a substantially constant level. It is possible to adjust the height. The lead wire terminal thus housed in the container 1 is immersed in the chemical solution 8 in the chemical conversion tank 7 as shown in FIG. Therefore, it can be immersed in the chemical liquid 8 up to the same position.

Incidentally, reference numeral 9 denotes a mounting jig, and the height of immersion into the chemical liquid 8 can be adjusted by means of bolts 10 and the like mounted thereon.
