[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a single cell when connecting a plurality of cells in series, and particularly to a terminal portion.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, in order to connect cylindrical batteries in series, Japanese Utility Model Publication No. 51-5686, Japanese Utility Model Publication No. 54-52640, etc., use a dish-shaped cap for connection to connect the battery members. Has been proposed. However, when a battery is connected using these dish-shaped caps, only the portion of the dish-shaped cap becomes thicker than the outer diameter of the battery. The increase in the thickness of such a part means that when this battery is incorporated into a device to be used, the volume of the device increases by the thickness part, and the battery cannot be stored compactly. Further, when such a connection cap is used, there is a problem that the connection part of the battery is easily broken by an external impact. Further, by using such a separate member called a cap for connection, the number of parts is increased, so that the manufacturing cost is increased and the manufacturing becomes complicated.

In order to solve the above problems, Japanese Patent Laid-Open No. 63-105460 proposes a battery connection cap. However, even if a battery is connected using such a connection cap, the battery connection portion may still be damaged if an external impact or the like is applied. In addition, since spot welding is performed, there is a problem in that the heat generated during welding adversely affects the battery.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems, and when batteries are connected in series, they can be firmly and easily connected, and the connection does not increase the vertical and horizontal dimensions of the battery. The purpose is to be able to store the used batteries in the equipment used in the minimum space.

[0005]

[Means for Solving the Problems]

 The battery of the present invention comprises a one-pole terminal having a cylindrical rising wall formed on one end surface and a convex other-pole terminal formed on the opposite other end surface. The convex-shaped other electrode terminal of the adjacent battery can be fitted in the recess formed by the rising wall, and the convex-shaped other electrode terminal is in the recess of the one-electrode terminal of the other adjacent battery. It is possible to mate.

Further, it is preferable that the one pole terminal is integrally formed with the battery lid. Further, it is preferable that at least two protrusions are formed on the inner peripheral surface of the rising wall.

[0007]

[Action]

 The battery of the present invention has a cylindrical rising wall on one end of one end and a convex other end on the other end, which is adjacent to the recess formed by the rising wall. It is possible to firmly and easily connect a plurality of batteries in series by press-fitting the convex-shaped other pole terminal of the battery, and the connection does not increase the vertical and horizontal dimensions of the battery. The batteries can be stored in the equipment used in the minimum space.

Further, since the projecting portions are formed at least at two places on the inner peripheral surface of the rising wall of the one-pole terminal, the battery is more firmly connected.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of a one-pole terminal 1 which also serves as a battery lid. FIG. 2 is a vertical sectional view of FIG. In FIG. 1 and FIG. 2, a one-sided electrode terminal 1 also serving as a battery lid has a bottomed cylindrical shape having a brim portion 2 and a cylindrical rising wall 3, and the cylindrical rising wall 3 is folded back. This constitutes the bottom surface 4. A recess 10 is formed by the rising wall 3 and the bottom surface 4.

Here, at least two protruding portions 5 are present on the inner peripheral surface side of the rising wall 3. This is to form the concave portion 6 by applying an external force from the outer peripheral surface side of the rising wall 3 and accordingly to form the protruding portion 5 on the inner peripheral surface side. Further, numeral 7 is a through hole for letting out the gas generated by the pressure rise inside the battery to the outside. FIG. 3 is a perspective view of the battery of the present invention in which the one-pole terminal 1 also serving as the battery lid is incorporated in the battery.

FIG. 4 is a side view when batteries are connected in series, and FIG. 5 is an explanatory view of the connecting portion in FIG. 4 and 5, the battery of the present invention has the one-pole terminal 1 also serving as the battery lid and the outer can 11 which are caulked and fixed via the insulating packing 12, and the power generating element (Fig. (Not shown) is inserted. The method of connecting the batteries will be described. The one electrode terminal 1 also serving as the battery lid is fitted with the other electrode 9 having the convex shape 8 formed from the center of the bottom surface. At this time, the outer diameter of the convex shape 8 of the other pole 9 and the inner diameter of the rising wall 3 of the one pole 1 are almost the same diameter, and are formed from the rising wall 3 and the bottom surface 4 of the one pole terminal 1. The convex shape 8 of the other pole 9 is press-fitted into the recess 10. At this time, the presence of the protruding portion 5 provided on the inner peripheral surface side of the rising wall 3 of the one-side element 1 allows the batteries to be reliably fixed to each other.

By fixing in this manner, the batteries are firmly connected to each other even when an external shock is applied to the batteries connected in series, so that the connection portion is rattled or bent. , There is no need to worry about disconnection. Further, in the present invention, the one-pole terminal of the battery also serves as a member for connecting the battery, so that a separate component for connection is not necessary. Therefore, the batteries can be easily connected in series simply by stacking the batteries of the present invention. Further, since there is no need for a separate member for connection, the dimensions in the vertical and horizontal directions at the time of connecting the batteries can be finished to the dimensions of simply stacking the batteries. Therefore, when storing such a battery in a device or the like, it can be stored in a minimum space.

[Effect of device]

 According to the present invention, when a plurality of batteries are connected in series, the battery has one pole terminal having a cylindrical rising wall formed on one end surface and a convex electrode formed on the opposite end surface. -Shaped other pole terminal, the convex other pole terminal of the adjacent battery can be fitted in the recess formed by the rising wall of the one pole terminal, and the other pole terminal of the convex shape Can be fitted in the recess of the one-pole terminal of another adjacent battery, so that the batteries can be easily and firmly connected to each other, and there is no need to use a separate member for connection. The vertical and horizontal dimensions are the same as the dimensions of simply stacking batteries. Therefore, when storing such a battery in a device or the like, it can be stored in a minimum space.
