Abstract: A battery module includes a printed circuit board (PCB) having a copper pattern; a flexible printed circuit board (FPCB) having a copper pattern; and a conductive bonding portion for bonding the PCB to the FPCB, wherein the copper pattern of the PCB and the copper pattern of the FPCB are electrically connected to each other by a conductive metal particles, and wherein at least one of the copper pattern of the PCB and the copper pattern of the FPCB has at least one or more alloy layers selected from a group consisting one or more of Ni—Sn and Au—Ni—Sn—Bi.

Abstract: A connector assembly for a battery pack may include: a first housing configured to support a first terminal; a second housing configured to support a second terminal electrically connected to the first terminal, and coupled to the first housing; and a fixing member detachably coupled to the second housing, and the fixing member is selectively disposed in a first position in which the second housing and the second terminal are mutually aligned, or in a second position in which the first housing and the second housing are prevented from being separated from each other.

Abstract: Provided is an ozone generator for generating ozone using high voltage discharging between an electrode plate forming a first electrode and a heat sink forming a second electrode. The ozone generator includes: an inner tube and a middle tube each of which is concentrically disposed, the electrode plate being interposed between the inner tube and the middle tube; an adhesive sealing both ends of the electrode plate; an electrode pipe for electrically connecting to a power source and disposed within the electrode plate; a passage formed through a middle of the heat sink; and an outer tube installed in an inner periphery surface of the passage, the outer tube being concentrically disposed to maintain a predetermined distance from an outer periphery surface of the middle tube.

Abstract: A vacuum cleaner capable of reducing noise, power consumption, and the discharging of fine dust particles, and eradicating mites, mold, and germs by blowing ozone is provided. The vacuum cleaner includes a main body, suctioning head, hose, ozone generator, and venturi. The main body includes an air suctioning blower installed within to impart suctioning force. The suctioning head includes a suctioning cavity. The hose connects the main body to the suctioning head, and includes an air discharging passage divided from an air suctioning passage. The ozone generator generates ozone and is installed on the suctioning head. The venturi connects a discharging end of the ozone generator to the air discharging passage. The suctioning force continuously circulates air through the air discharging passage, the suctioning cavity, and the air suctioning passage, and the ozone generated by the ozone generator is supplied to the suctioning cavity through the venturi.

Abstract: This invention relates to an ozone generator for deodorizing and sterilizing without doing harm to a human body, and being applied to general home appliances, includes a discharger for discharging using high voltage generated from a high-voltage generating portion and an ozone generator for generating ozone by secondary-discharging with a medium of metal inside of the discharger. Thus, ozone can be generated in a place of high temperature, humidity and much dust and at a lower cost, and since a glass tube, a glass bar and a ceramic stick are employed, product cost is reduced.
