The present invention relates to a storage battery that has an improved connection structure 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 prevent connection failures. The aim is to provide a storage battery that can drastically reduce the Conventionally, as a connection structure between a storage battery terminal (hereinafter simply referred to as a terminal) and a connection plate, a tightening structure using bolts and nuts as shown in FIG. 1 has been used. This connection structure is assembled by applying the connection plate 2 to the terminal 1, and then tightening the terminal 1 and connection plate 2 with bolts 4 and nuts 5 through washers 3 using a torque wrench. Since this method is easy to work with, it is used in many stationary battery connections. However, with this connection structure, there is no problem because the contact is maintained sufficiently at the initial stage of tightening, but after long-term use, the contact surface deteriorates and the problem arises that contact resistance increases. Therefore, there is a drawback that periodic retightening is inevitably required. The present invention provides a storage battery having a terminal-to-connection plate connection structure that can eliminate the above-mentioned drawbacks.The present invention provides a storage battery having a terminal-to-connection plate connection structure that can eliminate the above-mentioned drawbacks. A storage battery with a structure that does not require retightening for a long period of time by sandwiching between the storage battery terminal and the die, tightening the die, connecting plate, and terminal with bolts and nuts, and cold pressure welding the terminal and the connecting plate. This is what I did. Hereinafter, the present invention will be specifically explained using the drawings. Figure 2 shows an embodiment of the present invention, in which 1 is a lead terminal, 2 is a copper connecting plate for connecting adjacent storage batteries, 3 is a washer, 4 is a bolt, and 5 is a nut. be. 6 is a die, and the die has the third
As shown in the figure, an annular convex portion 7 is provided on one side surface, or an insertion hole 8 for a bolt 4 is provided at the center thereof.
Reference numeral 9 indicates a press-contact portion between the terminal 1 and the connection plate 2. Next, to explain the method of assembling the storage battery of the present invention, first, the connecting plate 2 is applied to one side of the terminal 1 and the washer 3 is applied to the other side, and then the annular convex portion 7 is placed on one side of the connecting plate 2 on the side of the connecting plate 2. Then, pass the bolt 4 between them, attach the nut 5 to the bolt 4, tighten the bolt 4 and nut 5 with a torque wrench, and press-fit the terminal 1 and the connection plate 2. Complete. After the pressure welding, gradually loosen the torque wrench and check whether the pressure welding is sufficient. If it is not sufficient, press the parts again. 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 for the connection structure of the storage battery 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. In addition, as mentioned above, since the connection structure of the storage battery of the present invention uses the die 6, sufficient pressure stress can be applied to the pressure contact surface during pressure welding, and the terminal 1 and the connection plate 2 can be easily and completely connected. can be pressure-welded. That is, since the annular convex portion 7 of the die 6 can intensively apply pressure contact stress to the pressure contact portion of the terminal 1 and the connection plate 2, the terminal 1 and the connection plate 2 can be easily and completely pressure contacted. The shape of the die 6 used in the connection structure 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. Next, in the storage battery connection structure shown in Fig. 2,
A 1 mm thick connecting plate 2 is used, and the die 6
The annular convex portion 7 has a width of 1 mm, a height of 0.9 mm, and a length of at least 5 times the width, and the surface to be pressed is surface-treated, and the pressing pressure is 40 kg/mm 2 , and the structure is as described above. The connection according to the present invention and the conventional connection structure as shown in Fig.
The following table shows the results of conducting each test at several locations and investigating the number of failures over a one-year period. The surface treatment of the pressure contact surface is to remove oils and fats and oxide films existing on the pressure contact surface, and this is done 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. In addition, the brush was degreased before use to remove any oil or fat adhering to it.
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.
