BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a replaceable internal battery with interchangeable terminals.

[0002]

2. Description of the Related Art With the increasing frequency of information-oriented social activities, the application of computers themselves has already evolved from centralized processing to distributed processing of information. Therefore, in general, the main factors to consider when constructing a system are It is the reliability of the current supply. And in order to secure the reliability of the current supply, it is necessary not only to express it on a personal computer applied at home, but also to supply reliable power with locality in the whole computer center or social system. ing. For this reason, the vendor has come up with an information / communication facility system non-interruptible power supply system (hereinafter referred to as UPS) that can work for a long time and is safe. It is intended to suppress the influence of the computer communication system and computer control equipment due to the generation of defective power source such as pulse, trap wave and disconnection in the power source, remove the defective phenomenon caused by the above current through this UPS, and load the equipment. Or improve effects such as driving stability. However, the design of battery life in the above-mentioned UPS that assists the existing computer is only 40 to 50% of the life of the Menboard, and therefore, once the life of the battery is over, the Menboard which is always integrated with the battery is required. At the same time, you have to throw it away. Generally, since it cannot be treated as a waste separately from the membrane, the sulfuric acid solution of the battery leads to a severe pollution problem with respect to the environment.

In addition to problems such as pollution, the above-mentioned conventional battery is a contact type battery which is mainly used for a commonly used general electric device and is placed on the electronic device. What is used is provided with grooves facing each other on both wall sides of the space where the battery is installed, and further, ridges corresponding to the grooves are provided on both sides of the battery main body. By sliding and fitting the above-mentioned pair of ridges into the groove, the connection between the terminal on the general battery surface and the terminal on the electric device contact surface can be achieved.

On the other hand, regarding batteries used in portable computers (eg, notebook type personal computers) which are now widely used, appropriate fixing devices (eg,
It is conducted by the contact between the computer board and the battery using a spring, etc.), but the above-mentioned part of the battery exposed to the atmosphere significantly reduces the contact area with the electrical equipment terminals due to the oxidation of air. This leads to a problem that it is easy or cannot effectively contact between the contact planes, which affects the efficiency of use of electricity.

In addition, general batteries are classified into (1) lead storage batteries, which are so-called secondary batteries, and (2) both types of rechargeable alkaline storage batteries. Prevention of pollution and protection of the environment are more severely required to ensure the quality of life required by the better people such as the government or the people. For the protection of the environment, lead storage batteries or alkaline storage batteries, which can be used by overlapping charging instead of the currently used general batteries, are becoming increasingly important. Considering the reliability and economic efficiency of the currently used batteries, the lead storage battery usage is almost 95% of the total battery usage. Can be confirmed. Therefore, the problem that actually existed only in the lead storage battery will be explained as follows. Traditional VRLA batteries (ie, valve-controlled lead-acid batteries) have similar advantages to the repeatable batteries described above, but sealed batteries designed to extend their service life are Excessive gas pressure may be generated inside due to misuse or abuse, so gas is automatically removed from the battery to the atmosphere by controlling the valve. A storage battery that is dead and must no longer be used must be replaced. However, when replacing the battery, there is a risk that the user may come into contact with the protruding terminal of the VRLA battery or cause a short circuit caused by carelessness.

[0006]

Other than the above-mentioned VR
The terminal protruding to the surface of the battery used for the valve-controlled lead storage battery in the LA battery can be used for discharging a large current in a general battery, but the positive and negative terminals having the terminal both protrude to the surface of the battery and are large. Since a large current flows inside the battery, a short circuit is likely to occur. Also,
As described above, in a general storage battery having a sealed ventilation port, in order to loosen the gas pressure therein, the ventilation port is opened, and exhaust operation is continuously performed from the ventilation port to the atmosphere, but for long-term use. However, the electrolyte inside is always reduced, and the drawback is that it cannot be recharged and it has a one-time usable life.

The user who replaces the battery must run the risk of a short circuit and is also inconvenient to replace. Conventionally, the conventional lead-acid storage battery described above, once it has been used, is integrated with the whole battery (for example, UP
There is no choice but to discard the S non-interruptible power supply system). Thus,
It wastes the use of resources and pollutes the environment with waste batteries.

Also in the alkaline storage battery, which occupies the next most important position, the general planar contact terminal is unlikely to cause the above-mentioned short circuit problem, but the contact area is reduced, so that the battery is not large. Since no current flows, and only a small current flows, the applicable range of batteries is limited.

[0009]

In view of the above problems, the terminal according to the present invention is embedded inside a compatible battery, and at the same time, a conventional terminal for connecting electric wires is provided, so that the user is careful not to use it. Thus, the risk of short circuit due to contact is avoided, and the insertable terminal used when connecting to a separately installed PC board is convenient when replacing with a new battery.

In order to achieve the above-mentioned object, a terminal accommodating tank is provided inside the terminal-equipped type compatible accumulator of the present invention, and in order to hide the above-mentioned terminals inside the battery, it is formed in this accommodating tank. In addition, the elasticity of the receiving part of the insertable terminal and the recessed tank with a specific shape that is recessed inside can be used. In addition to the traditional battery terminal structure for connecting electric wires, the insertion type terminal has an insertion contact type structure that can insert and use a PC board, which not only has the convenience of replacing the battery itself,
By increasing the contact area of the entire terminal in the present invention, not only large current discharge but also small current discharge can be used, so that the range of application of the battery becomes wider.
