Abstract: An overvoltage protection for a coaxial line has a coaxial line section with a first inner conductor which is concentrically surrounded by an outer conductor, with a first branch line in the form of a short-circuit line with a second inner conductor branching off from the coaxial line section in the radial direction, and with the inner conductor being accommodated in a first recess in the outer conductor of the coaxial line section.

Abstract: A cable plug for a coaxial cable, in particular comprising an external corrugated conductor, comprises an electrically conductive housing, which concentrically surrounds an insulated internal conductor, in addition to fixing elements which are used to connect the external conductor of the coaxial cable electrically and mechanically to the housing of the cable plug. The cable plug permits a particularly simple configuration and assembly. To achieve this, the fixing elements ensure a fixed and sealed connection between the external conductor of the coaxial cable and the housing of the cable plug.

Abstract: The invention relates to a fiber-lens arrangement having a fiber array with a substrate provided with a plurality of adjacent, interspaced, parallel, homogeneous V-shaped grooves for receiving and orienting the end sections of a plurality of optical fibers, and a separate lens array which matches the fiber array. The fiber array has, in a common base body, a number of lenses corresponding to the number of optical fibers. The arrangement of said lenses in the base body corresponds to the arrangement of the optical fibers in the V-shaped grooves of the fiber array on the substrate. One such fiber-lens arrangement enables a simple, precise and flexible adjustment to be carried out, using a separate adjusting mechanism for the optical orientation of the lens array on the fiber array, said adjusting means co-operating with the V-shaped grooves of the fiber array.

Abstract: A broadband patch antenna including a planar metallic patch sheet that is provided with right-angled edges and is disposed at a predetermined first height above and parallel to the planar base area of an electrically conducting reflector, and a device for feeding an RF signal into the metallic patch sheet. The feeding device encompasses a conductor which is guided in a vertical direction and is insulated through the base area of the reflector and terminates at a feeding point on the metallic patch sheet. To significantly improve the broadband range while keeping the structure of the antenna simple, the metallic patch sheet has the shape of a cross and the conductor of the feeding device is an inner conductor of a coaxial conductor that is positioned between the base area of the reflector and the metallic patch sheet.

First and second ferrules are provided having bores supporting ends of optical fibers. A first end of the first ferrule is received in one end of the bore of the sleeve via one end of the bore of the receptacle. A first end of the second ferrule is received in the other end of the bore of the sleeve via the other end of the bore of the receptacle. A locking mechanism is provided for locking the first and second ferrules to the receptacle.

Abstract: A hose for conveying media that generate electrostatic charges, wherein the hose includes a hose wall enclosing an interior delimited by an inner surface, wherein the hose wall is constructed from a flexible, electrically poor conductive or non-conductive base material, and at least one electric line element extending in the longitudinal direction of the hose and being integrated into the hose wall to dissipate electric charged, wherein at least one region of a cross section of the hose wall adjoining the interior of the hose has an electrical conductivity greater than the base material, and wherein the at least one electric line element is directly connected to the region of increased electrical conductivity. In such a hose, improved dissipation of the charges without impairing the remaining hose properties is achieved.

Abstract: The coaxial plug-and-socket connector is for high frequencies, particularly in the GHz range, and comprises a socket part and a plug part as well as an elastic electrical contact element. The contact element connects the outer conductor of the socket part to the outer conductor of the plug part and is placed between the plug part and the socket part. The contact element comprises a number of elastic parts that, while under radial elastic stress, form a contact point to the outer conductor of the socket part and a contact point to the outer conductor of the plug part. Said contact points preferably lie in a plane running perpendicular to the longitudinal axis of the plug-and-socket connector and near a face of the plug part. The connector is stable up to approximately 65 GHz.

Abstract: A surge suppressor configured to receive signals from a coaxial line having a signal carrying inner conductor and a grounded outer conductor. The surge suppressor includes an inner conductor exhibiting capacitance and configured to connect to the coaxial line inner conductor, an outer conductor configured to connect to the coaxial line outer conductor and to ground, and an inductor formed of a wire encapsulated in an encapsulating material electrically coupling the inner conductor and the outer conductor. RF signals in the surge suppressor's operating bandwidth pass through the surge suppressor relatively unimpeded while electrical surges will be diverted through the inductor to the outer conductor, and therefore to ground, and possible residual pulses will be blocked from passing through the surge suppressor by the capacitance.

Abstract: An optical plug-in connection for connecting polarization-maintaining optical fibers includes at least two plug-in connectors and a coupler into which the plug-in connectors are plugged from opposite ends. The optical fiber to be connected is fixed to the fiber end of a ferrule in each of the plug-in connectors. The coupler is provided with a guiding device into which the ferrules enter from opposite ends when the plug-in connectors are plugged into the coupler. Also provided are means for positioning the ferrules at an angle from each other. The ferrules can be positioned in relation to each other in a much more precise manner by means of such an optical plug-in connection by configuring the positioning means in such a way that the ferrules are placed at an angle that is relative to the guiding device when the plug-in connectors are plugged into the coupler.

Abstract: An antenna (10) having an emitter element which is positioned in front of a conductive reflector (13) and has a three-dimensional cast part. The cast part is implemented as conductive and has a closed peripheral structure (11) having alternating constrictions and bulges. The peripheral structure (11) spans an imaginary surface (14) which is intersected by at least two planes of symmetry (15.1, 15.3) of the cast part. At least two fastening elements (12.1, 12.2) are provided, which extend essentially perpendicular to the imaginary surface (14) and support the peripheral structure (11) at two points which lie on one of the planes of symmetry (15.1; 15.3). At the lower ends (16), the fastening elements (12.1, 12.2) are connected to the reflector (13), the fastening elements (12.1, 12.2) also being used for electrical excitation of the emitter element.

Abstract: An antenna mounting device is provided to fasten an antenna to an external element (2). Two support members (3) are provided which may be attached to said external element (2) with a space in between. Each support member (3) has at least one cylindrical section (4) oriented in the direction of said space whereby a brace (10) of the antenna (1) may be attached onto said cylindrical section (4) by means of a fastening element (5) encompassing the same. This allows simple installation of antennas to walls, for example, with considerably lower installation requirements while having the same adjustment possibilities as with an auxiliary pole. For example, the antenna mounting device may be directly employed for fastening three antennas to one pole through completion of said antenna mounting device with a complementary support member.
