A chassis member for a chassis of an electronic device is disclosed. The chassis member includes an aluminum alloy layer and an alumite layer serving as an outermost layer of the chassis member and disposed on a surface of the aluminum alloy layer. A grain size of an aluminum alloy in the aluminum alloy layer is between 40 m and 50 m.

Embodiments described herein provide methods of processing an electronic component, comprising mixing a bio-based polymer having sulfur-reactive substituents with a sulfurization catalyst and a solvent to form a coating material; applying the coating material to an electronic component; and removing the solvent to form a sulfur-reactive polymer coating that is resistant to sulfur penetration. The bio-based polymer may be made by bacterial fermentation of unsaturated fatty acids.

A case with assembly structure includes a body, an engaging portion, a fixing element and an elastic element. The body has an accommodating slot and the engaging portion is disposed in the accommodating slot. The fixing element is slidably disposed on the main body and is located on one side of the accommodation slot and adjacent to the engaging portion. The fixing element has a hook. One end of the elastic element is disposed to the body and another end is disposed to the fixing element. The fixing element is moved between a fixed position and a release position along a first direction. When the fixing element is moved to the release position, the hook of the fixing element is moved along a second direction to hook the engaging portion. Meanwhile, the elastic element is made the fixing element be pulled toward the fixed position.

A heat dissipating structure includes an integrated circuit; a bracket; a heat sink; a housing; a first fastening member that is inserted into a first fastening hole provided to the bracket, and is inserted into a fastening hole provided to the heat sink, and that assembles the integrated circuit to the bracket and the heat sink, while a surface of the integrated circuit contacts with the bracket, and another surface contacts with the heat sink; and a second fastening member that is inserted into a second fastening hole provided to the bracket, and into a fastening hole provided to the housing, and assembles the bracket to the housing. The heat sink includes one surface that contacts with the housing, the one surface being on a side opposite to a surface contact with the integrated circuit, and the one first fastening member is positioned spaced from the housing.

Electronic devices are provided with ejectable component assemblies. Each ejectable component assembly may include a tray that can be loaded with one or more types of removable module, such as a mini-SIM card and a micro-SIM card, and inserted into the device. Each assembly may also include a base coupled to a circuit board for electrically coupling with the removable module, a cage for biasing the module down against the base, and a guide for retaining the module at a functional insertion position within the device.

The invention relates to a field device for automation engineering having a housing, wherein the housing has at least one associated pushbutton switch. Operation of the pushbutton switch is detected, according to the invention, inside the housing without the presence of mechanical or electrical passageway through the wall of the housing. For this, the housing does not need to have a blind hole or an inwardly directed depression. This is achieved by a rigid arrangement of a first element for producing a magnetic field on the outer wall of the housing. By means of interaction with a second element for influencing the magnetic field of the first element, which is arranged in an operating element, a variable magnetic field is produced inside the housing. This magnetic field is sensed by a sensor. On the basis of the alteration in the magnetic field, the sensor can determine whether the pushbutton switch is currently being operated.

A device incorporating both a magnet and a living hinge may be employed to construct cases to protect electronic devices and to function as a closure for cases and lidded containers. Such cases often can be bent three 360? allowing the cases to be either closed protecting devices therein are closed upon themselves allowing the case to function to secure an electronic device to a substrate such as an article of clothing. The devices of the disclosure can also be used to organize and hold loose items together.

An electronic component is provided with a housing, a conductive terminal loaded on the housing, and an external conductive member loaded on the housing. A gap between the external conductive member and the conductive terminal is defined by a protrusion formed on the housing or the external conductive member.

Junction boxes for enclosing and making electrical connections to LED drivers are disclosed. The junction boxes include a bottom or base and a cover. Dividers arising from the base divide the junction box into high-voltage and low-voltage compartments. A cut-out open at the top of each divider allows drivers to be placed in a junction box without having to pull wires through holes or openings. Typically, the base is open along one long sidewall, with the cover being L-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes.
