摘要： An over-current protection device is disposed on a circuit board and configured to protect a battery. The over-current protection device includes a resistive device, at least one insulation layer and a weld electrode layer. The resistive device exhibits positive temperature coefficient behavior. The insulation layer has a thickness of at least 0.03 mm. The weld electrode layer is configured to weld a strip interconnect member to electrically coupled to the battery, and has a thickness of at least 0.03 mm. The insulation layer and the resistive device are disposed between the weld electrode layer and the circuit board. The circuit board, the resistive device and the weld electrode layer are electrically coupled in series. The association of the resistive device and the weld electrode layer has a thermal mass capable of withstanding welding the strip interconnect member without significant damage to the over-current protection device.

摘要： An over-current protection device includes a first conductive member, a second conductive member, a resistive device and a temperature sensing switch. The first conductive member includes a first electrode foil and a second electrode foil those are formed on a same plane. The resistive device is laminated between the first conductive member and the second conductive member and exhibits positive temperature coefficient or negative temperature coefficient behavior. The temperature sensing switch can switch the first electrode foil and the second electrode foil between electrically conductive status and current-restriction status, e.g., open circuit, according to temperature variation. The threshold temperature of the temperature sensing switch is lower than the trip temperature of the resistive device.

摘要： A variable impedance composition according to this aspect of the present invention comprises a conductive powder in an amount from 10% to 30% of the weight of the variable impedance composition, a semi-conductive power in an amount from 30% to 90% of the weight of the variable impedance composition, and an insulation adhesive in an amount from 3% to 50% of the weight of the variable impedance composition. According to one embodiment of the present invention, the variable impedance material presents a high resistance at a low applied voltage and a low resistance at a high applied voltage. As the variable impedance material is positioned in a gap between two conductors of an over-voltage protection device, the over-voltage protection device as a whole presents a high resistance to a low voltage applied across the gap and a low resistance to a high voltage applied across the gap.
