摘要： The invention relates to a surge protection device comprising at least one surge protection unit, consisting of a substantially U-shaped socket part and a plug part which can be fixed in the socket part and which receives a surge protection means. Insulated electric conductors on or in the socket part are contacted by means of vampire taps or displacing terminals. The surge protection device also comprises openings or perforations formed in the socket part for receiving conductors. According to the invention, the openings are selectively designed so that the electric conductors are inserted into or through the openings, and the openings are exposed in a socket part region which can be covered by the socket part such that cutting surfaces located on the base of the plug part penetrate the conductor insulation during the plug-in process and directly contact the respective conductor.

摘要： A connection apparatus circuit includes an isolation transformer, an impedance matching network, a high-voltage capacitor and a first high-voltage surge protector. The isolation transformer has a first coil and a second coil, wherein the first coil has a first terminal, a second terminal and a center tap. The impedance matching network is coupled between the center tap and a relay terminal. The high-voltage capacitor is coupled between the relay terminal and a ground terminal. The first high-voltage surge protector is coupled between the relay terminal and the ground terminal. When a high-voltage surge exceeds a default value between the first terminal or the second terminal and the ground terminal, the first high-voltage surge protector is conducted to clamp current on the impedance matching network.

摘要： A protection circuit provides transient protection to a solid state circuit of a line interface for wired telecommunications media at a voltage level below the power supply of the solid state circuit and prevents transient currents from entering the power supply distribution where they might cause damage to the protected interface and other circuits. The protection circuit uses a MOSFET, the gate of which is provided with a bias derived from a power supply of the solid state circuit being protected. The bias causes the MOSFET to be always on such that the MOSFET provides an immediate and high transconductance path to ground for transient currents from the line interface.

摘要： Methodologies and structure are provided for use in a communications line that transmit data without plain old telephone service (POTS), or splits the POTS service from the data service, to inhibit oxidation of electrical connections within the physical communications line between the central office of a service provider and a subscriber premises and/or subscriber equipment. A direct current load is drawn by a sealing current terminator circuit that is electrically coupled across the communications line at a convenient location proximate or within the subscriber's location so as to assist in providing oxidation reducing direct current flow along a portion of the communications loop coupling the service provider with the subscriber.
