News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to a secondary battery.
"Rechargeable secondary batteries are largely used as a power source for portable electronic devices. At present, a pack-type battery is widely used as a secondary battery. A pack-type battery is a form of a battery with integration of a bare cell and a protection circuit module (PCM) into one unit.Products from Global Silicon protctive film Products Suppliers. A pack-type secondary battery typically includes a bare cell, a protection circuit module, and an upper case. The protection circuit module is attached to one surface of the bare cell, and the upper case is attached to cover the protection circuit module.
"In order to keep pace with recent trends toward continued downsizing of portable electronic devices employing secondary batteries as a power source, there is an increasing demand for a secondary battery to have a smaller size. In a conventional pack-type secondary battery,manufacturers and Double sided PET industry tape Products suppliers Directory. the protection circuit module employs a common printed circuit board (PCB) which may limit downsizing of the secondary battery.All the latest Releasing film Products in small size and in resumable."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "Therefore, in accordance with embodiments of the present invention,stocks a huge selection of aluminum foil tape. a secondary battery is provided including a protection circuit module with a reduced thickness through use of a flexible printed circuit board (FPCB) to achieve downsizing of the battery.
"Additionally, a secondary battery is provided including a protection circuit module using an FPCB having a terminal structure firmly connected to a battery charger or external load.
"In one embodiment, a secondary battery is provided including a bare cell and a protection circuit module electrically connected to the bare cell. The protection circuit module includes a flexible printed circuit board including a circuit board body and a terminal-forming portion providing a first external terminal and a second external terminal and a support member to which the terminal-forming portion is attached, the support member having a support surface spaced from the circuit board body.
"The support member may include a support plate having the support surface, and a plurality of support legs extending from the support plate and fixed to the circuit board body. Further, ends of the support legs of the support member have a contact surface in contact with the circuit board body. The protection circuit module may include circuit elements mounted on the circuit board body, the circuit elements occupying a space between the support plate and the circuit board body, and the space may have a depth of at least 0.6 mm.
"In one embodiment, the circuit board includes a connecting portion between the circuit board body and the terminal-forming portion,Matco Packaging Llc suppliers of BOPP tape, and the circuit board body is a lengthwise-extending strip having a the connecting portion extending from a side or an end of the circuit board body.
"The support member may be fixed to the circuit board by soldering, adhesion or a surface mount technology process, and the support member may be made of metal or an injection-molded synthetic resin. Further, the support surface of the support member may be insulation-treated, such as with an insulating tape.
"Further, the terminal-forming portion may be attached to the support surface of the support member, such as by a double-sided tape. Additionally, the circuit board may include an upper surface having circuit elements mounted thereon, and a lower surface opposite to the upper surface on which the first external terminal and the second external terminal are mounted."
