The present invention relates to an improvement in the connection method between a connection plate and a storage battery terminal for connecting adjacent storage batteries, and its purpose is to eliminate the need for retightening for a long period of time, and to minimize failure of the connection part. We are trying to create a storage battery that can reduce the amount of electricity used. Conventionally, as a method for connecting storage battery terminals (hereinafter simply referred to as terminals) and connection plates, a tightening method using bolts and nuts as shown in FIG. 4 has been used. In this method, a connecting plate 2 is applied to a terminal 1, and then the terminal 1 and the connecting plate 2 are tightened with a bolt 4 and a nut 5 through a washer 3 using a torque wrench. This method has good workability, so
Used in many stationary battery connections. However, with this method, there is no problem because the contact is sufficiently maintained at the initial stage of tightening, but after long-term use, the problem arises that the contact surface deteriorates and the contact resistance increases. However, it has the disadvantage that it necessarily requires periodic retightening. The present invention provides a method for connecting a terminal and a connection plate that can eliminate the above-mentioned drawbacks.The present invention provides a method for connecting a terminal and a connection plate that can eliminate the above-mentioned drawbacks. A connection method is used in which the die, connecting plate, and terminal are clamped together with bolts and nuts with the terminal reinforcing metal frame inserted between the terminal and the die, and the terminal and the connecting plate are cold-welded. By adopting this method, it is possible to obtain a storage battery having a structure that does not require retightening for a long period of time. Hereinafter, the present invention will be specifically explained using the drawings. Fig. 1 shows an example of the connection between a terminal and a connection plate obtained by the connection method of the present invention, where 1 is a lead terminal, 2 is a copper connection plate, 3 is a washer, 4 is a bolt, and 5 is a connection plate made of copper. It's Natsuto. 6 is a die, which has an annular convex portion 7 on one side as shown in FIG.
Further, an insertion hole 8 for a bolt 4 is provided in the center thereof. Reference numeral 9 denotes a terminal reinforcing metal frame, which is configured in the shape shown in Fig. 3, and is fitted into the terminal 1 to prevent the terminal 1 from being deformed during pressure welding of the connection plate and to ensure pressure welding. It fulfills the following. 1
0 is a press-contact portion between the terminal 1 and the connection plate 2. As can be seen from FIG. 1, in the connection method of the present invention, a connection plate 2 is applied to one side of the terminal 1, a washer 3 is applied to the other side, and an annular convex portion 7 is attached to one side of the connection plate 2. Place the die 6 so that it is on the side, fit the terminal reinforcing metal frame 9 into the terminal 1, pass the bolt 4 between them, attach the nut 5 to the bolt 4, and tighten the bolt 4 and nut 5 with a torque wrench. The terminal 1 and the connection plate 2 are tightened, and the terminal 1 and the connection plate 2 are welded together by cold pressure. After the pressure welding, gradually loosen the torque wrench and check whether the pressure welding is sufficient. If it is not sufficient, press the welding again.
If it is sufficient, tighten the bolt 4 and nut 5 and remove the terminal reinforcing metal frame to complete the connection. The merits (residual thickness ratio) of lead and copper are respectively
16 and 14, which are somewhat small values, but since copper is a material that is relatively easily pressure-welded, even lead and copper can be sufficiently pressure-welded. Further, the pressure welding method used in the connection method of the present invention is based on overlapping pressure welding, which is a suitable method because it does not require a very large pressure value compared to butt pressure welding. Further, as described above, since the connection method of the present invention uses the die 6 and the terminal reinforcing metal frame 9,
In pressure welding, in particular, the pressure welding stress can be sufficiently applied to the pressure contact surface, and the terminal 1 and the connecting plate 2 can be easily and completely pressure welded. That is, dice 6
The annular convex portion 7 transfers pressure welding stress between the terminal 1 and the connecting plate 2.
The stress can be applied concentratedly to the pressure welding part, and the terminal reinforcing metal frame 9 blocks lateral plastic deformation of the terminal 1 during pressure welding, preventing the pressure stress from escaping, making it easy and complete. The terminal 1 and the connection plate 2 can be brought into pressure contact with each other. The shape of the die 6 used in the connection method of the present invention is preferably a shape with an annular convex portion 7 as shown in FIG. 2 in order to facilitate plastic deformation of the connection plate 2. It may also have a shape with partial convex portions or the like. The shape of the terminal reinforcing metal frame 9 is such that it prevents the terminal 1 from being plastically deformed laterally during pressure contact, for example, the shape shown in FIG. 3. Further, when carrying out the connection method of the present invention, in order to increase the effect of pressure welding, it is desirable to perform surface treatment on the pressure contact surfaces to remove oils and fats and oxide films present on the pressure contact surfaces. Next, in the structure shown in Fig. 1, a connecting plate 2 with a thickness of 1 mm is used, and a die 6 with an annular convex portion 7 having a width of 1 mm, a height of 0.9 mm, and a length of at least 5 times the width. The method according to the present invention, in which the contact surface was surface-treated and the contact pressure was set at 40 kg/mm 2 , was used as described above, and the conventional method shown in Fig. 4 was carried out at several locations. The table below shows the results of investigating the number of failures over a one-year period. In addition, the surface treatment of the pressure-contact surface was performed using rotary brushing with a brush diameter of 150 mm and a wire diameter of 0.2 mm at a rotation speed of 3000 rpm, and the brush was degreased before use to remove the adhesion of oils and fats. . The total pressing force was determined by determining the area to be pressed from the shape of the punch of the die, multiplying that value by the pressing pressure, and confirming the total pressing force with a torque wrench.
