JPH0689709A - Secondary battery assembly and its housing device - Google Patents

Abstract

PURPOSE:To provide secondary battery assembly and battery housing device with which use of an apparatus, which operates usually with a secondary battery assembly, is made practicable, by accommodating a dry cell directly in the battery housing part even in a case the apparatus runs out of battery. CONSTITUTION:A battery housing part is configured so that a primary battery (dry cell) can be accommodated directly. For the purpose, the minus terminals of the primary battery are laid in line, and each is equipped with a resilient terminal. The plus terminals of the primary battery are laid in line, each of which is equipped with a non-resilient terminal. A secondary battery is formed larger than the size of the laid primary batteries, and a curving configuration is provided in the primary battery housing part. The contour of the secondary set battery is such that one end lies on the minus terminal extension line of the primary battery and the other end lies in a position greater/smaller than the plus terminal extension line of the primary battery, and therein terminals of the batteries are provided separately from the terminals of the primary battery.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery accommodating device, and more particularly to a battery accommodating device capable of directly accommodating a primary battery such as a dry battery and a rechargeable secondary assembled battery.

[0002]

2. Description of the Related Art A rechargeable secondary battery such as nickel cadmium is used as a power source for recent home electric appliances, and is used in a wide range of fields from a VTR integrated camera to a handy cleaner. As the secondary battery pack, one that can be used for a long time and one that can be used for a short time can be made. For example, in the technique disclosed in Japanese Patent Laid-Open No. 2-179990, the secondary battery used in a VTR integrated camera is used. Regarding a battery pack, a battery and a battery storage system are disclosed in which a secondary battery pack that can be used for a long time and a secondary battery pack that can be used for a short time can be attached to and detached from each other.

By the way, the secondary assembled battery must be charged when the battery runs out. Therefore, if the equipment used runs out of battery, prepare a fully charged secondary assembled battery in advance. Otherwise, the equipment cannot be used. As a means for saving this, the prior art discloses a structure in which the primary battery is stored in a storage pack and then attached to the equipment. For example, the magazine "Video SALO
N "(published by Genkosha) July 1992 issue" Video Movie All Guide "Appendix 39, as described as a dry battery pack, the alkaline battery is stored in a dry battery pack having the same shape as the secondary battery pack. The method of using a power source for driving a video camera is introduced.

[0004]

Here, inconveniences in terms of usability of each of the above-mentioned technologies will be described.

First, in the first prior art, it is convenient in that the type of the secondary battery pack can be changed and a long-time use battery and a short-time use battery can be used. If you do not do this, you will not be able to use the equipment.

Next, considering the dry battery pack of the second prior art, even when the secondary assembled battery runs out of battery, the main unit can be driven by the dry battery pack and the alkaline dry battery. If you do not have a dry battery pack, you may not be able to use the device even if you get a dry battery. Generally, for equipment that is often used outdoors, it is rare to charge the battery in advance as described above or to prepare a dry battery pack (sold separately from the main unit) in the main unit. It often becomes unusable in actual use.

The present invention has been made in view of the above points,
Provide a secondary battery pack and battery storage device that allows the main equipment to be used by storing dry batteries directly in the battery storage unit even when the equipment that normally uses the secondary battery pack runs out of battery To do.

[0008]

In order to achieve the above-mentioned object, a secondary assembled battery and a battery housing device according to the present invention include:
First, the battery storage portion is formed into a shape that can directly store the primary battery (dry battery). Therefore, the negative terminals of the primary batteries are arranged on the same line, and each negative terminal is provided with a spring-like terminal. On the other hand, the positive terminals of the primary battery are arranged on the same line, and each negative terminal is provided with a non-spring type terminal. Further, the size of the secondary assembled battery is configured to be larger than the size in which the primary batteries are arranged in parallel, and a curved shape is provided in the storage portion of the primary battery. On the other hand, the outer shape of the secondary assembled battery has a shape having one end on the minus terminal extension line of the primary battery and the other end at a position larger / smaller than the plus terminal extension line of the primary battery. This is achieved by providing a secondary battery terminal separately from the terminal.

[0009]

Since the primary battery can be directly stored in the battery storage portion, the primary battery can be stored without using a separate component such as a dry battery pack for storing the primary battery. By arranging the negative terminals of the primary battery on the same line, providing a spring-type terminal on each of the negative terminals, arranging the positive terminals on the same line, and providing a non-spring-type terminal on each of the negative terminals, the primary battery Also, it becomes easy to attach and detach the secondary assembled battery. By making the size of the secondary assembled battery larger than the size in which the primary batteries are arranged in parallel, erroneous insertion of the primary battery and the secondary assembled battery is prevented, and in principle, the secondary battery is better than the primary battery. It is possible to deal with the larger battery pack. By providing the storage portion of the primary battery with a curved shape, the primary battery can be stored stably. Two
The outer shape of the secondary battery has a shape having one end on the minus terminal extension line of the primary battery and the other end at a position larger / smaller than the plus terminal extension line of the primary battery. By additionally providing the terminal of the secondary assembled battery, it is possible to prevent accidental insertion of the primary battery and the secondary assembled battery.
