Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a backup power supply device for use in a computer system as a countermeasure against power outages, which accommodates a large amount of storage batteries in a small space housing, and Concerning a mounting structure suitable for enabling safe and easy maintenance @ [Background of the Invention] In recent years, as a new external storage device that constitutes a computer system, a new external storage device that is compatible with conventional magnetic disk devices and is used as a host device. From this perspective, a semiconductor storage device that can be used as a magnetic disk device has been developed.In this type of device, data is recorded as the operating state of the semiconductor, so
Memories are erased when the power is turned off. Therefore, even if an unexpected power outage occurs, it is essential to continuously supply power to the semiconductor storage device, and for this purpose, backup power supply equipment using a large capacity storage battery is required. Figure 1 shows an example of this kind of equipment conventionally used.
Shown in Figure 2. Fig. 1 shows a large storage side 1 arranged side by side on a pedestal 2, and Fig. 2 shows a case installed on the pedestal 2 in a stepped manner. The normally used storage battery 1 requires maintenance work such as checking and replenishing the electrolyte, and retightening after a certain period of time because the output terminal part 1a is lead and the electrical connection is screwed. In order to improve work efficiency and prevent the risk of electric shock, it is necessary to make the upper space 3 wide as shown in Figures 1 and 2. This requires a large number of storage batteries 1, but as a result of the above structure, that is, a large amount of empty space 6, there is a drawback that the equipment area and volume become large. Furthermore, these devices lack a sleek appearance and are not suitable for installation inside a computer room. On the other hand, power supply equipment for semiconductor storage devices is installed side by side with other computer peripheral equipment, and a large number of storage batteries are housed in a relatively small sealed box to ensure safe and efficient maintenance. [Objective of the Invention] An object of the present invention is to stably house a large number of storage batteries in a relatively small portable sealed box, The object of the present invention is to provide a power supply device that safely and efficiently maintains these storage batteries and houses a large power capacity in a space-saving housing. [Summary of the Invention] A conventional power supply device that houses a large number of storage batteries When the device is used in a computer system, there are problems in terms of safety, maintainability, and space, as mentioned above.Therefore, we have developed multiple sealed storage batteries with terminals that do not require electrolyte replenishment and are highly safe.
They are assembled into a single assembly type sealed box body, and each is easily connected with a cable with a crimp terminal without using retightening screws, ensuring a constant power capacity, and forming one cartridge. In order to realize a small floor space by mounting a large number of IJ Tsuji (this car), a large number of IJ Tsuji were housed in a case with a shelf-like structure and slide rails on each level, and each was connected with a cable with a plug. Ensure large power capacity as a whole. The cartridge box described above securely holds the storage battery so that it does not move, and
Constructed to prevent electrical contact, increasing safety,
It also has a structure that allows it to be installed and removed into the housing and securely fixed, making maintenance easy.After the cartridge is stored in the housing, the inside is covered by the front plate of the cartridge, so the outermost door There is also a wall, which can form a double structure. Additionally, a ventilation fan is installed at the top of the housing to exhaust heat and gas generated from the storage battery. On the other hand, since the power supply device is connected to another external storage device, the inner wall of the casing is covered with a metal material for safety reasons such as fire.
