The present disclosure relates to an assembly comprising a housing and at least one busbar for connecting a printed circuit board disposed in the housing to a power supply present outside the housing, wherein the housing has a penetration, from which the busbar projects, wherein a magnetic core and a gasket accommodating the magnetic core are placed in the housing penetration in a media-tight manner, and the gasket, together with the magnetic core, encompasses the busbar in a form-fitting manner.

A plug connecting unit for connecting a cable circuit in a cable circuit housing with a sensor module in a sensor module housing, comprising a wireless interface for energy- and/or data transmission between the cable circuit and the sensor module. A first section of the wireless interface is arranged in the cable circuit and a second section of the wireless interface is arranged in the sensor module. The wireless interface is surrounded by a magnetic shielding and the magnetic shielding is arranged in the cable circuit housing and/or in the sensor module housing.

An electronic device is provided. The electronic device includes a circuit board, a connector, a shielding frame and a shielding cover. The connector is disposed on the circuit board. The shielding frame is disposed on the circuit board, wherein the connector is disposed in the shielding frame. The shielding cover is detachably connected to the shielding frame, wherein when the shielding cover is combined with the shielding frame, an inlet is formed between the shielding frame and the shielding cover, and the shielding frame and the shielding cover are adapted to block an interference signal.

An electromagnetic leakage prevention device includes a bottom surface, first side walls, second side walls, a first connecting portion, and a second connecting portion. The first side walls are coupled to a side of the bottom surface. The second side walls are coupled to a side of the bottom surface opposite the first side walls. The first connecting portion is coupled to ends of the first side walls away from the bottom surface. The second connecting portion is coupled to ends of the second side walls away from the bottom surface. A distance between the first side walls and the second side walls increases along a direction away from the bottom surface.

An equipment rack, including an electronic equipment enclosure defined by RF-shielded walls. Openings in the RF-shielded walls are provided for being aligned with complimentary-sized and shaped openings in one or more like data center equipment racks and adapted for permitting a shielded electromagnetic connection between two or more racks. At least one access door in the enclosure is provided for facilitating access to the electronic equipment in the rack. Panels are provided for covering the respective openings in the RF-shielded walls when the openings are not being used to permit an electromagnetic interconnection between two or more racks. Feedthroughs of the invention communicate signals and power into and out of adjacent enclosures while allowing the enclosures to each form a Faraday cage, protecting electrical and electronic systems within the enclosure from electromagnetic threats such as EMP, HEMP, lightning and geomagnetic storms.

An electromagnetic shield member including: a case including a groove in which an electric wire is to be housed; a cover configured to be attached to the case and cover the groove; and a pressing mechanism that is housed in the groove and configured to press the electric wire, wherein the pressing mechanism has a wall that covers an outer circumferential surface of the electric wire in conjunction with the groove, and a presser provided on the wall and configured to press the electric wire.

A device includes a first and a second part, relatively rotatable, and data transmission structures for contactless transmission of data. The data transmission structures include a transmit and/or receive facility a coupling facility on the two parts. The transmit and/or receive facility extends over a small angle and the coupling facility extends over a complete circle. Data is transmitted between the facilities at a transmission frequency. The two parts include walls encompassing a tunnel interior space extending completely around the axis of rotation. The data transmission structures are arranged in the tunnel interior space. The walls are electrically conductive structures reflecting electromagnetic alternating fields in the transmission frequency range. An absorber structure is arranged at least on a part of the walls toward the tunnel interior space and the absorber structure absorbs electromagnetic alternating fields in the range of the transmission frequency.

An electromagnetic interference (EMI) shield system is disclosed. The system may include an EMI gasket assembly configured to prevent radio frequency (RF) radiation from escaping through a gap between a RF connector and the enclosure. The gasket assembly may include a gasket including a receiving portion. The receiving portion may be configured to receive a portion of a shaft of the RF connector. The gasket may be formed of a compressible material. The gasket assembly may include a spacer configured to couple to a portion of the shaft of the RF connector. The spacer may be configured to compress the gasket against a portion of the enclosure when the spacer is rotated in a first direction. The spacer may be configured to provide electrical continuity between the radio frequency connector and the gasket by causing the gasket to form an electrical connection with the enclosure when the gasket is compressed.

An apparatus and method for shielding for surface-mount LTCC components and filters to increase the signal isolation from input signal port to output signal port, and to increase isolation from other electrical signals external to the component or filter. Some embodiments include an interposer two-sided and plated through printed circuit board to provide a constant impedance transition from a surface-mount device input and output ports to corresponding input and output connection points of a circuit on a printed circuit board onto which the device is mounted, including a ground plane transition.

An anti-noise component for a connector including a plug on an end of a coaxial cable and a jack at an opening of a metal housing of an electronic device. The anti-noise component includes a cylindrical first conductive member where the plug is inserted, and a cylindrical second conductive member where the first conductive member is inserted. The plug is held inside the first conductive member. An external thread portion is formed on the first conductive member and an internal thread portion is formed inside the second conductive member. The external thread portion mates with the internal thread portion. A flange portion is formed on the second conductive member and a joining portion is formed on the flange portion. The joining portion abuts an outer face of the metal housing. This prevents a gap from forming and leaking electromagnetic noise between the joining portion and the metal housing.
