A transition for an optical fibre cable (11) through a partition. The optical fibre cable (11) is received inside a shield pipe (1, 4), which shield pipe (1, 4) is of an electrically conductive material. The shield pipe (1, 4) is received in an axial through opening (6, 21) of the holding means. One end of the shield pipe (1, 4) is received inside a holding means having a sealing function.

The present invention provides a housing having a housing shell with an opening, a guidance component and a door leaf set. The guidance component is arranged in the housing shell and extending along the direction away from the opening. The door leaf set has a first door leaf and a second door leaf. The first door leaf is pivotally connected the housing shell to enable the first door leaf to rotate to a first position or a second position relative to the opening. Wherein when the first door leaf is positioned at the first position, the first door leaf shields a portion of the opening; when the first door leaf is positioned at the second position, the first door leaf extends into the housing shell and defines the first installation space with the guiding component. Wherein when the first door leaf is positioned at the first position, the second door leaf can rotate to a third position or a fourth position relative to the first door leaf; when the second door leaf is positioned at the third position, the second door leaf shields another portion of the opening; when the second door leaf is positioned at the fourth position, the second door leaf extends into the housing shell and defines the second installation space with the guiding component.

A wire harness including: a wire; an electromagnetic wave absorber that has a through hole through which the wire passes, and that is provided so as to surround an outer circumference of the wire; and a movement restrictor that is provided adjacent to the electromagnetic wave absorber, and that restricts movement of the electromagnetic wave absorber in a length direction of the wire.

Systems for optimizing mounting points for coaxial RF connectors, including a printed circuit board (PCB) comprising a coaxial radio frequency (RF) connector; a faceplate comprising an opening adapted to receive the coaxial RF connector; and a bushing positioned within the opening, wherein the coaxial RF connector is positioned within the bushing.

A Faraday enclosure apparatus may include one or more sewn seam portions constructed to prevent signal leakage through stitch apertures in the seam. A vestibule section facilitates signal-shielded movement of electronic devices between the ambient environment and the main cavity of the enclosure. A connector filter may be mounted to extend through a wall of the enclosure to manage wired power and signal communications entering and exiting the main cavity of the enclosure. Foldable side walls facilitate the collapsibility of the enclosure for compact transport and storage.

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.

A revolver-type feed-through for TEMPEST-grade electromagnetic shielding where one or more non-electric signal leads pass through a wall of a cabinet or other enclosure comprises a housing having a conical inner surface, the housing being attachable to the wall through a first attachment means; and a plug member having a conical outer surface matching the conical inner surface of the housing, the plug member being attachable to the housing through a second attachment means, wherein the conical inner surface of the housing and/or the conical outer surface of the plug member have recesses forming, when the plug member is attached to the housing, a plurality of waveguides. The first attachment means and the second attachment means being operable by one or more operating members located, with the feed-through in installed position, exclusively on one side of the wall, so that the first attachment means and the second attachment means are exclusively operable from the said one side of the wall.

A receptacle cage includes cage walls including a top wall, a first side wall, a second side wall, and a bottom wall. The cage walls form a module channel configured to receive a pluggable module. The cage walls extend between a front end and a rear end of the receptacle cage. The receptacle cage includes a lifting device located in the module channel proximate to the bottom wall. The lifting device is located remote from the front end. The lifting device has a lifting surface configured to engage the pluggable module and lift the pluggable module into the module channel to an elevated position lifted off of the bottom wall.

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.
