Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a cylindrical storage battery. 2. Description of the Related Art With a cylindrical storage battery, it is difficult to manufacture a 6V or 12V battery (referred to as a monoblock type battery) integrally formed with a plurality of unit cells (referred to as cells) like a rectangular storage battery. When a high voltage is required, a large number of cells are externally connected in series or parallel to form an assembled battery. In the case of serial connection, connection is made in the order of positive electrode → negative electrode → positive electrode → negative electrode. On the other hand, in the parallel connection, the positive electrodes and the negative electrodes are bundled and connected. [0003] Storage batteries are used for a variety of purposes. In recent years, in the event of an emergency when the power supply is cut off, power is supplied from the storage battery to equipment until the power supply is restored. It has become. In this case, since a commercial power supply is used, for example, 100 V or 220 V
In the case of a cylindrical storage battery, since it is usually supplied in a single cell, it is necessary to connect a very large number of batteries to a required voltage. [0004] When a storage battery is installed in a device, it is usual to install the storage battery in a single cell and connect the terminals in the device by a lead wire or the like, and it is difficult to automate the connection, and it must be performed manually. is the current situation. It is a difficult task to connect the positive and negative terminals of a large number of storage batteries by hand without mistake. If you make a mistake, you will destroy the equipment and the storage battery, and you must avoid incorrect connections. [0005] As a method of avoiding erroneous connection when connecting a storage battery, there is provided a cylindrical storage battery in which positive and negative terminals are easily identified. Means for Solving the Problems Conventionally, the positive and negative terminals of a storage battery have the same terminal shape and the same length, so that erroneous connection frequently occurs at the time of connection. -It is characterized in that the length of the negative electrode terminal is made different. That is, in a cylindrical storage battery provided with a spirally wound electrode plate group wound between a positive and negative electrode plate via a separator, positive and negative terminals are arranged on the same end face of the storage battery, and positive and negative terminals are arranged. It is characterized in that the length of the negative electrode terminal is different. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on embodiments. FIG. 1 is a perspective view (a) and a sectional view (b) showing an embodiment of the present invention.
Reference numeral 2 denotes a positive terminal, and 3 denotes a negative terminal. When the terminal lengths are different as shown in FIG. 1, the operator can easily determine whether the terminal is the positive terminal or the negative terminal, and erroneous connection can be avoided. If the ratio between the lengths of the positive and negative terminals in this case is too small, the discrimination function deteriorates. On the other hand, if it is too large, one of the terminals will become an abnormally high terminal, causing problems such as an unnecessarily long lead wire for connection with the counter electrode and a troublesome connection. It can be said that the ratio is suitably in the range of 20 to 50%. In the embodiment, the embodiment in which the positive electrode terminal is made longer and the negative electrode terminal is made shorter has been described. As described above, as a method of preventing erroneous connection when a large number of single-cell cylindrical storage batteries are externally connected by lead wires or the like, the length of the positive / negative electrode terminals is reduced. The method of changing is simple and effective, erroneous connection can be greatly reduced, and the industrial effect is great.
