A connector plug has an integrated electrical radio frequency (RF) suppression filter comprising a metallic filter housing which is slipped over the connector plug and electrically contacted to a ground conductor which extends from one end of the device to the other. The ground conductor is designed with a broad surface and is preferably in the form of a cross-shaped member in a central region and having ends connected to the terminal elements of Y-capacitors of the RF filter. The ground conductor is separated from the electrical filter components by an insulating lamina and the overall arrangement is encapsulated with plastic to form the plug prior to receiving the metallic housing thereover.

An EMC-/EMI-filter module for use with unscreened data and signal lines comprises a LC filter utilizing a quadruple inductance is contained in a 16 terminal dual-in-line package with a specified raster dimension.
摘要:
An endoscopic system according to the invention, in particular for colonoscopy, includes a flexible endoscope with an elongate, flexible shaft, a regulator part, and also an operating part which can be placed on or pushed onto the shaft and which has at least one control element, wherein the endoscopic system furthermore includes a shaft stop, which can be secured on a patient support and which has a locking mechanism, controllable by the at least one control element, for locking the shaft against movement in a longitudinal direction of the shaft.
摘要:
A brake-disc/hub assembly is provided with a disc/hub connection for connecting a brake disc to a brake disc hub. The brake disc includes support elements on the inner circumference thereof, the brake disc hub is provided on the outer circumference thereof with cams, and intermediate elements are radially distributed in the circumferential direction between the brake disc hub and the brake disc, extending into cavities running in the circumferential direction between the cams and the support elements and, hence, providing a transfer of the braking force from the brake disc to the brake disc hub. Each intermediate element includes two shoulders running at least completely or essentially in parallel to each other, whereby one shoulder contacts a corresponding cam and the other shoulder contacts a corresponding support element, embodied such that the total thickness of opposing shoulders on the elements may be reduced for disassembly thereof.
