A hybrid surge protector for a network interface device (NID) is disclosed. The hybrid surge protector includes a fail-safe spring connected to the ground electrode of a three-electrode gas tube. Tabs on the fail-safe spring are held away from the gas-tube end electrodes by a fusible element. The hybrid surge protector also includes metal-oxide varistor elements ('MOVs') in contact with the gas-tube end electrodes and with the ground electrode via an MOV spring. This arrangement provides for two initial paths to ground-one path from the gas-tube end electrodes to the ground electrode through the gas tube, and another from the gas-tube end electrodes to the ground electrode through the MOVs and the MOV spring. The dominant path to ground starts as the MOV ground path but switches to the gas-tube path as the gas tube becomes activated. Another path to ground via the fail-safe spring is also available should the gas tube overheat. A surge protection module that includes the hybrid surge protector is also disclosed.

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.

Method and apparatus for balancing capacitance in hybrid overvoltage protection device

An apparatus and method for reducing and balancing the off-state capacitance of an overvoltage protection circuit utilizes one or more diode networks electrically connected in series with an overvoltage protection device. The overvoltage protection device is selected from the group consisting of a gas tube, an MOV, a transient voltage suppressor (TVS) diode and a TVS thyristor. Preferably, the overvoltage protection device is a solid-state overvoltage protector (SSOVP) having at least one thyristor. The diode network includes a plurality of diodes electrically connected in parallel and arranged with opposing polarities so that the circuit is bi-directional. Preferably, the diode network includes a first set of two or more stacked diodes electrically connected in parallel with a second set of two or more stacked diodes and arranged with opposing polarities, and the capacitance of the diode network is less than the capacitance of the thyristor.

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. The overvoltage protection device is electrically connected between a pair of connection nodes in the bridge circuit. The bridge circuit is made up of multiple diodes arranged along each of the legs of the circuit, which extend between the tip line and the ring line and the connection nodes. At least two diodes are arranged in series or in parallel along each leg of the bridge circuit to steer the excess voltage on the tip line or the ring line, or both, through the overvoltage protection device to ground. The use of multiple diodes on each leg of the bridge circuit reduces the effective off-state capacitance of the overvoltage protection device, thereby permitting the bridge circuit to be utilized for high frequency transmission line applications, and increases the overall surge current handling capability of the bridge circuit.

A customer bridge for a terminating device includes a base defining an interior cavity and a base cap attached to the base and substantially covering the cavity. At least a pair of wire insertion holes formed through the base cap extend into the cavity for receiving twisted-pair tip and ring wires. The customer bridge further includes at least a pair of corresponding insulation displacement contacts disposed within the cavity. An actuating arm pivots between a disconnected position wherein the twisted-pair tip and ring wires do not engage the corresponding pair of insulation displacement contacts and a connected position wherein the twisted-pair tip and ring wires engage the corresponding pair of insulation displacement contacts. The wire insertion holes are located on the top surface of the customer bridge to permit the twisted-pair tip and ring wires to be inserted from immediately above the terminating device.

A protective device for excess current utilizes a fuse that incorporates a printed circuit board. The printed circuit board has a trace on one side which is of a desired width, length, and thickness of material for opening if excess current for a selected duration of time is reached. The printed circuit board is mounted in an insulated housing. The lower side of the substrate may also have a conductive layer connected to the housing or ground. The printed circuit board and overvoltage protector may be tailored for impedance matching. An excess voltage protector may be incorporated with the printed circuit board for conducting to ground if excessive voltage is encountered. The housing has two terminals which are connected to the printed circuit board and voltage protector. These terminals may be conventional coaxial cable connectors.

Coaxial fuse and protector

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.
