The present invention prevents sheathed electrical wires from becoming damaged by a shield shell. A shielded conduction path includes: a conduction path main body in which sheathed electrical wires are surrounded by a tubular braided wire; an inner holder through which the sheathed electrical wires pass and that is made of a synthetic resin; a shield shell to which the braided wire is fixed, and that can house the inner holder and is made of a metal; a lock hole formed in a circumferential surface of the shield shell; and a lock arm that is formed in the inner holder, and locks the inner holder and the shield shell in an attached state by locking to the lock hole.

A connecting end portion of a shield pipe with respect to a shield member is waterproofed. A shield conduction path includes: a shield pipe having a connecting end portion opened obliquely downward; a braided wire fasten to an outer periphery of the portion by a swaging ring; a plurality of wires inserted into the pipe and braided wire; a rubber shield grommet and surrounding a fastening region between the braided wire and swaging ring; a binding band that fixes an upper end portion of the grommet to an outer periphery of the pipe in a liquid tight manner; a tube formed of synthetic resin surrounding the braided wire and having an upper end portion surrounding a lower end of the grommet; and exterior adhesive tape wound in a liquid tight manner from an outer periphery of the upper end portion of the tube over an outer periphery of the grommet.

A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. Alternatively, a panel for a broadband electromagnetic shield includes a composite fiber-reinforced core having opposed surfaces and a layered electrically-conductive composite cover disposed on a surface of the core. The cover includes a first stratum of porous metal exhibiting pronounced low-frequency electromagnetic shielding properties and a second stratum of electrically-conductive elements exhibiting pronounced high-frequency electromagnetic shielding properties secured in an overlapping electrically-continuous relationship to the first stratum, the first stratum being a metallic lattice, and the electrically-conductive elements being a non-woven veil of electrically-nonconductive metal-coated fibers.

The present disclosure relates to a display apparatus and an electronic device, relating to the technical field of display. The display apparatus may comprise a display panel, a main circuit board, a bridging circuit board, and a first shielding adhesive tape. The main circuit board may be provided on the back surface of the display panel; the bridging circuit board may be provided at the side of the main circuit board distant from the display panel, and may be connected to the main circuit board in a binding mode; and the first shielding adhesive tape may be provided at the side of the main circuit board distant from the display panel, and expose the bridging circuit board.

The present disclosure provides a circuit board for high frequency transmission and a shielding method. The circuit board for high frequency transmission includes: a first shielding film, a second shielding film and a circuit board body. The circuit board body includes a first surface and a second surface that are arranged opposite to each other. The first shielding film covers the first surface, and the second shielding film covers the second surface. The circuit board body is provided with a wire region. The first shielding film and the second shielding film are in electrical connection at a lateral side of the wire region. Therefore, leaky waves at the lateral side of the circuit board body are effectively avoided, and the circuit board body is thin in structure.

Disclosed is a shield structure, comprising a shield bracket, a shield cover, and a shield layer. The shield cover is formed with openings. The shield layer is spliced with the shield cover through a conductive tape layer and covers all openings. The shield cover is formed with openings and a light shield layer is spliced with the shield cover and covers the openings, greatly reducing the weight of the shield cover while ensuring the shielding effect, without compressing space for other elements. The shield layer is thin, capable of lowering down the shield, dissipating heat effectively, reducing the temperature of the whole machine and providing a good environment for the operation of the whole machine, without affecting the shielding effect; and the conductive tape layer is spliced with the shield layer, thus allowing multiple assembling without damaging the whole structure, and facilitating subsequent repair.

This disclosure relates to a multi-piece shield comprising a fence, a lid, and an insert. The lid attaches to the fence, which is attached to the circuit board. The lid is a relatively thick, flexible material for supporting the insert. The lid has a recess so that the insert can be recessed into the lid to position the insert closer to the circuit for enhanced heat absorption. The insert is made of a thicker heat absorbing material than the lid, again to facilitate heat absorption. The insert can be press-fit into the recess of the lid. The lid can have a dovetail configuration to retain the insert in the lid.

A composition comprising discrete functionalized carbon nanotubes attached to microfibrillated fibers and a plurality of the discrete carbon nanotubes are opened ended is disclosed. The composition may further comprise electroactive, photoactive, magnetic or catalyst particles. These new compositions can be used in energy storage or energy collection devices such as batteries, capacitors, photovoltaics and sensors.

An NFC tag shielding system for a multi-layer product of printed and/or non-printed layered material(s) includes a plurality of layers of printed and/or non-printed materials. The system includes a first on-metal NFC tag applied to a first layer of material of the plurality of layers and a second on-metal NFC tag applied to a second layer of material of the plurality of layers. The first and second on-metal NFC tags are aligned along an axis perpendicular to planes of the first and second layers of material. The system also includes an RF shielding layer disposed between the first and second on-metal NFC tags. The RF shielding layer is positioned along the axis and extends parallel to the first and second layers of material a distance covering at least a projected area of the larger of the first or second on-metal NFC tag. The RF shielding layer provides signal shielding between the NFC tags so that a user wishing to read the first NFC tag on the first layer of material will not unintentionally read the aligned second NFC tag on the second layer of material.
