Abstract: An electronic device having liquid-resistant modifications that prevent liquid ingress into an opening (or openings) in an enclosure of the electronic device is disclosed. For example, the electronic device may include a coating formed from a liquid-resistant material that is applied internally to the enclosure. The electronic device may further include a frame that carries a protective transparent layer designed to cover a display assembly. In order to secure the frame with the enclosure, the electronic device may include an adhesive assembly disposed over an outer perimeter of the coating. The adhesive assembly may include several adhesive parts initially separate from one another. However, with the adhesive parts between the frame and the enclosure, the adhesive parts can be compressed by the frame and the enclosure, causing the adhesive parts to expand and engage each other. As a result, the coating and the adhesive parts provide a seal against liquid.

Abstract: An electronic device having several modifications designed to prevent liquid ingress into an opening (or openings) of the electronic device is disclosed. For example, the electronic device includes a SIM tray having a sealing element designed to provide a seal at an opening that receives the SIM tray. The sealing element may include a first section and a second section extending from the first section, with the first section designed to bend with respect to (and in some cases collapse onto) the second section. The electronic device may further include an audio module fitted with a sealing element. The sealing element may include extensions extending away from a main body of the sealing element, with some extension designed to engage the audio module, and other extensions designed to engage an audio module interface. The sealing element provides a seal against liquid ingress into the audio module.

Abstract: A data cable can include a plurality of insulated conductors twisted into pairs, an intumescent tape surrounding one or more of the insulated conductors, and a jacket. Each of the plurality of insulated conductors includes a conductor and an insulation layer. Data cables being fluoropolymer-free or halogen free are also described herein.

Abstract: In some designs, getting a flexible circuit (flex) to assume a bent state can be helpful in efficiently routing electrically conductive pathways. One efficient way to implement soldering of flexes in a bent state during a reflow operation is to manipulate paneling that hold batches of the flexes to reliably maintain a suitable bend in those flexes. In some embodiments, a flex can be surface mounted to a portion or the whole of an electric device during a reflow operation during which the bent state is maintained by paneling that is at least partially attached to a periphery of the flex. Another solution is to utilize vacuum or hot glue fixtures to maintain a bend in the flex during surface mounting and reflow operations.

Abstract: A cable includes an inner layer surrounding a conductor and an outer layer surrounding the inner layer, and the outer layer is formed from an extruded outer layer composition including an at least partially cross-linked resin including a base polyolefin and a weak acid source, an inorganic flame retardant, and one more of an organic char former and a spumific agent. The cable passes the Underwriters Laboratory (“UL”) 1581 VW-1 Flame Spread Test and one or more of the UL 44 Long-Term Insulation Resistance Test at 90° C. and the ceramifying requirements of International Electrotechnical Commission (“IEC”) 60331-21. Methods of manufacturing such cables are also disclosed.

Abstract: An electronic device may have a printed circuit to which electrical components are mounted. The electrical components may include a thermal sensor and a pressure sensor. A through hole in the printed circuit may receive the shaft of a standoff The standoff may be soldered to plated metal on the sides of the through hole. A screw or other fastener may secure the printed circuit to a housing for the electronic device. A ring-shaped metal member may be soldered to the printed circuit. The ring-shaped metal member may form a bumper that surrounds the screw or other fastener and the thermal sensor. The pressure sensor may have a port through which ambient pressure measurements are made. A dust protection cover such as a fabric or other porous layer may cover the port.

Abstract: The present invention relates to cable covering compositions (insulation or jacket) for wires and cables that are fire and water resistant.
