Abstract: A remote monitoring system for telecommunication enclosures includes a low profile or flush mounted sealed transceiver or antenna unit, an electronic module inside of the enclosure electrically connected to the transceiver and a communication device to send signals to the electronic module through the transceiver. The sealed housing generally comprises a portion extending through the exterior surface of the enclosure. In some embodiments, the transceiver may include a radio frequency antenna, a photoelectric cell, a light sensor or an infrared sensor, and the communication device may be a handheld device, a transponder, or a networked computer.

Abstract: A sealed housing (10) accommodates at least one electric or electronic component (12, 14), and has a portion (20) extending through the mounting surface, as well as a rotation preventor (16, 28) preventing rotation of the housing (10) relative to the mounting surface. A kit of parts includes at least one such housing (10) and at least one spacer (18). A combination of the housing or kit of parts and a door, preferably of a cabinet or an installation room, or a cabinet in the field of telecommunications having the mounting surface is described. A use of a friction enhancing element, preferably an O-ring, for mounting a housing to a mounting surface in a non-rotatable manner is also described.

Abstract: A heat-management system is described for use in a cabinet containing electronic equipment (15) that produces a flow of heated air when in operation. The system comprises: an evaporator (32) positioned in the path of a heated air flow produced by the said equipment, to take up heat therefrom; a condenser (34) positioned above the evaporator in the path of a flow of cooling air, to transfer heat to the ambient air outside the cabinet; and a heat pipe 36 connecting the evaporator directly to the condenser to transport heat from the evaporator to the condenser.

Abstract: The device comprises a demagnetization coil (1) wound from electrically conducting insulated wire (5) and surrounded by an electrically insulating sheath (7). A connection member (17) is connected to the two ends of the wire (5). The connections (19) between the connection member (17) and the wire (5) are surrounded by an electrically insulating envelope constituted by a sheet (21) of electrically insulating foil, which is folded so that the connections (19) and the adjoining parts of the sheath (7) are disposed between the facing parts of the sheet (21). The edges of the sheet (21) conducting each other are connected to each other by means of a welding connection (23). The sheet is further connected by means of a welding connection (23) to the sheath (7) and to an envelope of the connection member (17). The sheet 21 constitutes an envelope for the connections (19), which is tight but for one lead-through opening for the connection member (17).

Abstract: A component holder is arranged on the windings of a diode-split line transformer. On this holder the diodes, the focus bleeder and the high-voltage bleeder can be arranged. The connection strips of the components act as soldering pins for the winding ends. The high voltage is connected via a socket connector which is clamped to the component holder by way of two snap tags. The socket connector is provided with radially extending ribs so as to increase the creepage path. The contact spring of the socket connector has a triangular shape, thus ensuring a large contact surface area.
