Patent number: 6950295Abstract: Metal oxide varistors (MOVs) are employed in surge protection devices, such as overvoltage protection devices, between a pair of signal lines and ground to reduce the capacitive imbalance introduced by the overvoltage protector, thereby improving higher frequency transmissions over twisted-pair telephone lines. The MOVs are sorted into subgroups having a capacitive tolerance of no more than about 1.0 picofarad. MOVs with asymmetrical electrodes can also be sorted to reduce both the capacitance and the capacitive tolerance of the MOVs. The sorted MOVs can then be electrically connected in parallel with a gas discharge tube on each signal line to produce an overvoltage protection device, for example a station protector for use at a customer premises, having a capacitive imbalance that does not exceed about 1.3 picofarads. The use of asymmetrical electrodes reduces the capacitance of the sorted MOVs to less than about 30 picofarads.Type: GrantFiled: December 17, 2002Date of Patent: September 27, 2005Assignee: Corning Cable Systems LLCInventors: Chanh C. Vo, John J. Napiorkowski, Barry G. Slotnick

Patent number: 6628497Abstract: An overvoltage protector bridge circuit for protecting telecommunications equipment against voltage surges on transmission lines utilizes an overvoltage protection device in a bridge circuit having multiple diodes arranged in series or in parallel on each leg of the circuit. The overvoltage protection device conducts when it reaches a threshold voltage potential.

Patent number: 6421218Abstract: An overvoltage protector assembly utilizes a gas tube having an electrically conductive terminal and an electrically conductive end cap for being selectively brought into electrical contact with the terminal to divert surges to ground. A toroidal non-conductive element having a central hole is disposed between an end cap and the terminal of the gas tube. A fusible element formed of a fluxed solder pellet is also disposed between the end cap and the terminal of the gas tube. The end cap includes at least one aperture and a raised projection on its outer surface so that axial forces applied by a spring clip are centrally applied to the end cap. Molten solder flows through the central hole in the non-conductive element and the aperture in the end cap when the overvoltage protector assembly overheats so that the end cap and the terminal are in electrical contact.Type: GrantFiled: March 24, 2000Date of Patent: July 16, 2002Assignee: Corning Cable Systems LLCInventors: Chanh C.
