For this reason, when a prescribed tightening torque is applied to the terminal portion, the bolt head portion sags and idles, so that there is a problem that the tightening strength cannot be secured.

A terminal member in which an arm portion is formed in the bolt head portion, and four arm portions are formed in a substantially cross shape when viewed from the axial direction of the bolt terminal;
It is known that a terminal member having a substantially one-character arm is used as a lead-acid battery terminal, and is fixed in a state where it is embedded in a conductive member to which a bolt head is fitted. However, if the fitting is performed in a state where the conductive member and the bolt head are intricate, the structure becomes complicated, processing time and cost increase, and the cost of the terminal portion occupies a high proportion of the cost of the lead storage battery. There were drawbacks.

弱く効果が不十分であった。On the other hand, there is a method of plating the conductive member with a lead alloy in order to strengthen the connection between the conductive member and the lead bush. As the lead alloy used for the plating, solder containing 60% of Sn having the lowest melting point is used in order to facilitate the fusion bonding between the conductive member and the lead bush. However, the bonding force between the plated conductive member and the lead bush was weak, and the effect was insufficient.

A stainless steel terminal member 1 having a terminal portion 1a and a bolt head portion 1b, a brass conductive member 2 screwed into the terminal portion 1a, and a conductive connection surrounding and surrounding the bolt head portion 1b and the conductive member 2. The lead bush portion 3 is formed. The conductive member 2 is formed by integrating a cylindrical conductive member 2a having an outer shape of 20 mm and a thickness of 7.0 mm and a conductive member 2b of a square prism having a side of 12 mm and a thickness of 3.0 mm having a thickness of 3.0 mm. The M8 tap is cut so that the terminal portion 1a of the terminal member 1 can be screwed into the center. On the surface of the conductive member 2, a plating layer of a Pb-90% by weight Sn alloy is formed in a range of 10 to 30 microns. The lead bush 3 is made of Pb-0.09wt% Ca.
-0.55 wt% Sn alloy. The conductive member 2
Combines a cylindrical conductive member 2a and a polygonal conductive member 2b as shown in FIG. 1 in order to increase the tightening strength.
As shown in FIG. 2, only a cylindrical conductive member may be used, and the present invention is not limited to this embodiment. Also, the terminal member 1 and the conductive member 2
Is not limited to the above.

い、好ましくない。The outer periphery of the conductive member 2 is a lead bush 3
And the upper surface is exposed to the outside. If the upper surface is covered with the lead bush 3, when the nut is screwed into the terminal portion 1a, the lead bush between the nut and the upper surface is crushed, which is not preferable.

が高まるからである。Next, the terminal shown in FIG. 2 was manufactured by changing the ratio of tin and lead in the plating of the conductive member 2, and the tightening strength was measured. The result is shown in FIG. From FIG. 3, it can be seen that the tightening strength is increased by increasing the Sn composition% of the Pb—Sn alloy. This is because the bonding force at the interface between the conductive member 2 and the lead bush 3 is increased by increasing Sn% and decreasing Pb%.

By applying the composition at a composition of 0% or more and increasing the bonding force at the interface between the conductive member and the lead bush, it is possible to secure a tightening strength of a specified value or more. Further, since the terminal structure can be simplified, an inexpensive lead-acid battery terminal can be provided.
