子Ｃを作製した。Next, a method of manufacturing the above terminal will be described. First, a stainless steel (SUS316) rod is processed to form a bolt, the bolt is electrolytically degreased, and after a washing step with water and hydrochloric acid, the surface of the bolt is plated with nickel having a thickness of about 5 μm. Next, the bolt 3 according to the present invention was manufactured by washing with water and performing solder plating with a ratio of lead and tin of 1: 9 on nickel plating. Next, the bolt 3 was set in a mold, and a molten Pb-Ca alloy was poured into the mold to obtain a terminal A of the present invention as shown in FIG. Further, a conventional terminal B as shown in FIG. 1 was manufactured in which a bolt made of stainless steel was embedded in a bushing made of a Pb-Ca alloy without plating. Furthermore, brass plating is applied to the solder plating, and Pb-Ca
A conventional terminal C as shown in FIG. 1 embedded in a bushing made of a system alloy was produced.

The degree of adhesion between the bolt 3 and the bolt 3, the terminal tightening strength, and the number of times the bolt can be repeatedly tightened were investigated. Table 1 shows the results. The degree of adhesion is indicated by the ratio of the joint surface to the contact surface of the contact between the bushing 2 and the bolt 3 after cutting the terminal in the vertical direction, and the terminal tightening strength is fixed to the bolt 2 with the bushing 2 fixed. Is the strength at which the bolt starts to rotate, and the number of times the bolt can be repeatedly tightened is shown by the number of times until the thread of the bolt is deformed by repeatedly mounting the lead wire terminal on the bolt.

金も可能である。From Table 1, the terminal A of the present invention is the conventional terminal B.
It can be seen that the tightening strength is excellent because the degree of adhesion between the bolt and the bushing is stronger than that of. Further, the conventional terminal C has the same degree of adhesion as the terminal A of the present invention, but the bolt is inferior in strength and deforms, so that the fastening strength is inferior to the terminal A. Furthermore, the terminal A of the present invention is the conventional terminal C.
It can be seen that the number of times until the screw thread is crushed (the number of times tightening is possible) is high because the strength of the bolt is superior to Also,
Since the terminal A of the present invention has a higher degree of adhesion than the conventional terminal B, the contact resistance between the bolt and the bushing is low and the conductivity is excellent. The bolt of this embodiment is made of stainless steel plated with nickel and solder, but tin or lead may be used in place of solder to obtain the same effect. Further, stainless steel has the same effect even if SUS304 or the like is used instead of SUS316. Further, it is preferable that at least a part of the bushing is not cylindrical so that it does not rotate during tightening, and a lead alloy such as Pb-Sb type is also possible in consideration of strength and workability.
