Abstract: The invention is a sliding contact and also a method for the production thereof. The sliding contact arrangement has two parts mounted to rotate relatively to one another. The first part has a metallic carrier ring with radial inner and outer sides, which is monolithically connected to at least one spring arm, which ends freely on one side on the inner side or outer side. The spring arm extends longitudinally relative to the inner or outer side at least in certain sections. The spring arm ends at a spring arm head having a contact surface facing away from the carrier ring, which is in sliding contact with a contact surface of the second part.

Abstract: An electric plug-in connector, comprising a plug head on which a union nut is rotatably disposed for screwing the plug-in connector together with a mating connector, can be screwed together with the mating connector under adherence to a prescribed tightening torque even without a torque wrench if the union nut consists of a threaded sleeve with a ring which comes into engagement with the threaded sleeve by way of driving parts at least during screwing on, of which the one driving part is dimensioned in such a way that it is shorn off by the other driving part when exceeding a tightening torque.

Abstract: A coaxial phase shifter for very high RF-powers includes an optionally-cooled housing which forms the outer conductor and in which a substantially U-shaped inner conductor made of a tube is arranged which comprises at each of its ends a cooling medium connection for guiding through a cooling medium. The U-shaped inner conductor is externally displaceable for changing its electrical length between a contact-making input-side inner-conductor connection piece and a contact-making output-side inner-conductor connection piece. The inner-conductor connection pieces are disposed coaxially in the outer connection flanges which make contact with the housing.

The VNA includes a wireless interface for reading at least the non-changeable data of a respective calibration component and for incrementing the stored number of the calibration processes performed with this calibration component.

Abstract: A coaxial overvoltage protector includes a coaxial line section from which a ?/4 short-circuit line branches off in a radial manner. The inner conductor of the short-circuit line is in electric contact with the inner conductor of the coaxial line section using a coaxial tubular capacitor. The tubular capacitor includes a conductive (metal) pin and the inner wall of the inner conductor of the coaxial line section. The conductive pin is arranged coaxially within the inner conductor of the coaxial line section and is electrically connected with the inner conductor of the short-circuit line, but is insulated from the inner conductor of the coaxial line section by a dielectric sleeve.

Abstract: A coaxial plug-type connector including an approximately hollow-cylindrical plug-head with an outside thread, and a cable-side conical annular face as a contact face for an outer conductor of a coaxial cable, and a threaded sleeve with an inside thread as a cable clamping component, does not require a special contact sleeve. The plug-type connector has a short length since the threaded sleeve includes an interior conical annular face for clamping an end-face edge region of the outer conductor of the coaxial cable against the conical annular face of the plug-head. In order that tool engagement faces on the plug-head may be dispensed with, the plug-head includes on the plugging-in side an interior profile for accommodating in a form-locked manner an assembly tool. The plug-head is configured such that assembly of an inner plug conductor and a plug dielectric can be performed from the plugging-in side.

Abstract: An adjustable filter includes an outer conductor, a first inner conductor, and a second inner conductor. The inner conductors are capacitively coupled on the same axis. The further may further include a third inner conductor capacitively coupled to both the first and second inner conductor. The third inner conductor is axially displaceable with respect to the first and second inner conductors. With this configuration, generation of intermodulation products can be minimized.

Abstract: A coaxial cable structure includes an outer cable conductor, and an angle connector, for example a 90° elbow connector, disposed on one cable end. The elbow connector is implemented by encapsulating the one cable end with thermoplastic material and including a metal sleeve which is placed in contact with the outer cable conductor to define an outer conductor of the elbow connector.

Abstract: A coaxial line includes an inner conductor, an outer conductor, and a series of insulating material struts located between the inner and outer conductors. At least some of the struts include conduits through which coolant may be supplied and removed. The line further includes connections that permit coolant to be sent through the line. In operation, coolant flows through the connections, along the struts, and into the inner conductor, cooling the coaxial line.

Abstract: A connector for coaxial cables having an annularly corrugated outside conductor includes a connector head which includes a conical annular surface on the cable side which establishes contact on the inner side of the boundary face region of the outside conductor of the cable. A sleeve can be screwed onto the connector head. A radially elastic clamping ring is housed in a first inside groove in the sleeve, to which a second inside groove of smaller diameter is adjacent on the cable side. The transition between the two inside grooves is configured in such a way that the clamping ring is radially compressed during screwing of the sleeve onto the connector head and tensions the boundary face region of the outside conductor of the cable against the conical annular surface of the connector head.

Abstract: In a coaxial connector, especially an integrally pre-mounted connector, the recess (7a) receiving the end of the coaxial cable can be sealed in the connector head (7) relative to the cable with the help of an integrated perimeter seal (10). For this purpose the perimeter seal (10) is received in a form-fitting manner in a pressure member (9) which establishes the electric connection between the outer cable conductor (3) and the conductor head (7) and connects the same in a manner so as to be secure against withdrawal. The perimeter seal comprises at least one and preferably several ring-like lips (10a, 10b, 10c) which project radially inwardly, deform when the pressure member (9) is slid onto the cable in the direction of its end (3a) and, after the clamping of the pressure member, stand again in the same radial plane as in the unloaded state.
