Abstract: A cable connector having a cable receiving part for holding at least one cable end and a contact part configured to secure the cable end in the cable receiving part such that it is mechanically pretensioned after connection. A clamping device may be associated with the receiving part, which may also include a tapered line chamber. The contact part may include an insulation piercing connecting device for securing the cable end, wherein the axial center line of the device may be parallel or not parallel with the axial center line of the line chamber.

Abstract: An electric appliance (1) comprising modules (2, 3) that can be juxtaposed to one another and interconnected using bridge elements (4) for transmitting electric signals and operating voltages. The modules (2, 3) and bridge elements (4) are provided with a pair of plug-in connectors (31) and also a pair of mating plug-in connectors (25, 26). The plug-in connectors (31) are each mounted in a cylindrical outer sleeve (36), and the mating plug-in connectors (25, 26) are mounted in cylindrical ducts or penetrations (19). An O-shaped sealing ring or gasket (38) is arranged about the circumference of each outer sleeve (36), so that the O-shaped gaskets (38) are under pressure when the outer sleeves (36) are inserted in the penetration (19) to interconnect the plug-in connectors (31) and the mating plug-in connectors (25, 26).

Abstract: In an antenna having at least one vertical radiator, preferably a vehicle mobile radiotelephone antenna, the at least one vertical radiator is connected to the ground on one end and to a vertical conductor fed against the ground on the other end by means of an impedance transforming device having an electrical length which is approximately one fourth the mean operating wavelength or an uneven multiple thereof. Said structure makes it possible for the at least one vertical radiator to have a uniform current occupancy over its entire length. By cooperating with the vertical conductor fed in a co-radiating manner, said occupancy exhibits high radiation power comparable to that of a &lgr;/4 monopole antenna despite the fact that the at least one vertical radiator has a smaller length which is approximately {fraction (1/10)} of the mean operating wavelength. The invention also describes advantageous embodiments or configurations of said antenna and practical arrangements of said antenna in vehicles.

Abstract: The present invention relates to a mobile transmission antenna (1) for vehicles that comprises a monopole (8) having a reflector (15) associated therewith. The unit thus formed is mounted on or adjacent to the inner surface of members of the vehicle which are permissive to electromagnetic waves, mainly the vehicle windows (3), so that said reflector (15) is directed towards the inside of the vehicle as seen from the monopole (8). During a transmission, this configuration reduces simply and economically to a harmless level the incident radiation of high-frequency energy that penetrates into the vehicle. The antenna is further protected from potential unauthorised handling from the outside and does not look like an radio-telephone antenna. In a particularly advantageous embodiment of the present invention, the radio-telephone antenna (1) is integrated with a device intended for other purposes, mainly with the third stoplight (4) mounted on the rear window (3) of the vehicle.

Abstract: A mobile antenna that repeatably can be attached and detached by rotation from motor vehicles. The antenna having a receiving portion electrically connected to a base body having a contact area for connecting to motor vehicles. The joined base body and receiving portion being encased in a jacket. The base body having grooves with flank surfaces also encased in the jacket; the grooves aligned in the lengthwise direction of the antenna so that the groove flank surfaces are essentially perpendicular to forces produced when the jacket is rotated for attachment and detachment of the antenna to or from the motor vehicle.

Abstract: Apparatus and method for producing a jacketed antenna, especially a mobile telephone antenna for motor vehicles, where the jacket is formed about antenna conductive parts in a mold. The mold having a centering pin for insertion in an antenna base body having a mating hole, and an antenna receiving portion attached to the base body so as to be aligned and centered in the mold by the centering pin to assure that the antenna conductive parts are completely encased in the jacketing material.

Abstract: A cable connector includes a core receiving part and a contact carrier joined by a connecting part. The core receiving part houses one or more cores of a cable. The contact carrier is provided with at least one contact element. By means of the connecting part, the core of the receiving part is held in electrical contact with the content element of the contact carrier.

Abstract: A cable clamp (10) for clamping cable (11) in a tubular cable feed-through part (12) that has a pressure piece (33) comprised of two pressure rings (13, 14) with a clamping spring ring (15) positioned between the two pressure rings (13, 14) to encircle the cable (11). The pressure rings (13, 14) are interconnected so that they are movable with respect to each other in an axial direction over a distance permitting the clamping spring ring (15) to have an inner diameter equal or somewhat greater than the outside diameter of the cable (11) or compressed so as to have an inner diameter that is less than the outside diameter of cable (11).

Abstract: An antenna for receiving electromagnetic waves, the antenna including a resonator having an electrically conductive bottom, an electrically conductive top, and an electrically nonconductive section between an electrically conductive side wall and the electrically conductive top. The electrically conductive bottom being in electrical contact with the electrically conductive side wall, which extends from the electrically conductive bottom to a grounding surface. The resonator having a dielectric disposed in an interior volume.

Abstract: A connecting device (1) for electrically connecting to at least two electrical conductors (39, 49) in a housing (2) having a tubular connecting plug (3), with a contact holder (10) in the tubular connecting plug (3), the contact holder (10) having contact elements (12) passed through recesses (14) in conductor holders (5) to make contact with the conductors. The connecting device (1) can be expanded into an array of connecting networks with, for example, plug-in connectors, cable bolted assemblies and connecting elements.
