The battery housing has a terminal mounting portion made of resin. The battery terminals are connectible with external terminals and are mounted to the terminal mounting portion so as to extend through the terminal mounting portion, so that each of the battery terminals has a first end positioned on one side of the terminal mounting portion and a second end positioned on an opposite side of the terminal mounting portion. At least one of the battery terminals is integrated with the terminal mounting portion, so that there is no substantial clearance between the at least one of the battery terminals and a part of the terminal mounting portion, through which the at least one of the battery terminals extends. | 08-16-2012 |
20130029197 | BATTERY PACK INCLUDING A SHOCK ABSORBING DEVICE - One aspect according to the present invention includes a battery pack and a shock absorbing device interposed between a battery cell holder and a case body and capable of keeping the battery cell holder and the battery cells not to directly contact with an inner surface of the case body. | 01-31-2013 |
20130224539 | BATTERY PACK - A battery pack may include a drainage device provided at a bottom portion of the housing case. The drainage device may include a drain hole communicating between the inside and the outside of the housing case, so that water introduced into the housing case is discharged to the outside of the housing case. The drainage device may be disposed between two of the terminal members that are connected to electrodes of the battery cells. | 08-29-2013 |
20130280573 | BATTERY PACK - Rubber cover main bodies close opening shapes of terminal-connection openings when a battery pack is placed alone without being mounted on a tool body. When the battery pack is removed from the tool body and is placed alone, it is possible to regulate the entry of foreign materials, such as water or dust, by the rubber cover main bodies. Further, when body-side connection terminals are connected to battery-side connection terminals, the rubber cover main bodies themselves can be deformed due to elasticity according to the slide movement of the body-side connection terminals such that the body-side connection terminals can be inserted into the rubber cover main bodies. Accordingly, it is possible to protect the battery-side connection terminals in the terminal-connection openings such that the battery-side connection terminals are not damaged by regulating the entry of foreign materials from the terminal-connection openings without hindering electrical connection caused by slide mounting. | 10-24-2013 |
