An electrical junction box with a built-in isolation transformer is provided. The junction box comprises an interior base portion having at least one opening, a transformer secured to the interior base portion and in electrical communication with low-voltage and high-voltage terminals, a cover configured to attach to a junction box base plate and housing the interior base portion and the transformer, and a gasket providing a watertight seal between the cover and the junction box base plate.

An electronic apparatus includes a housing that houses an electronic component, and a first cover and a second cover that cover the housing, wherein the electronic component is oriented along and on an inner side of a first sidewall of the first cover, wherein a side surface of the electronic component that faces the first sidewall has a cut, wherein the first cover has a recess that is depressed from the first sidewall toward the inner side in such a manner as to conform to the cut, and wherein the first cover is fastened at the recess to the second cover with a fastening member.

A sealing assembly for mating two sections of an electrical device enclosure is disclosed. The enclosure includes a top and bottom joinable section. The sealing assembly includes a first sealing section disposed on the top joinable section that has both first and second upper projecting lip extensions. The second upper projecting lip extension has a height less than the first upper projecting lip extension and forms a channel therebetween. A second sealing section is disposed on the bottom joinable section, and includes a downward projecting lip extension and channel. The downward projecting lip extension is offset from the first section first upward projecting lip extension when the top and bottom joinable sections are joined. At that point the downward projecting lip extension engages within the channel of the first sealing section, and the second upper projecting lip extension of said first sealing section is engaged within the second sealing section channel. The second sealing section channel can include a compressible gasket for waterproofing.

An apparatus for sealing an enclosure having a front and a back and an opening on the front. A door with an inner face and an outer face, and the door is rotatably mounted to the front of the enclosure and configured to cover the opening when the door is closed. A first rim surrounds a periphery of the opening and has a first outer edge. A first gasket is attached to the first rim and configured to form a watertight seal between the front of the enclosure and the door when the door is closed. A second rim on the door is sized to surround the periphery of the opening when the door is closed. A second gasket is attached the second rim and configured to form a watertight seal between the front of the enclosure and the door when the door is closed.

Provided is a power conversion device that has improved assembling workability and that realizes downsizing thereof. The power conversion device includes: an electrical component; a casing enclosing the electrical component and terminals connected to the electrical component and an outside, the casing having a plurality of opening portions in which the terminals are disposed; and a casing lid covering the opening portions. A shaft seal provided so as to be in contact with a side surface contiguous with a rim of an opening portion among the opening portions, and a surface seal provided so as to be in contact with a surface contiguous with a rim of an opening portion among the opening portions, are disposed so as to be in contact with the casing lid.

Portable electronic devices are provided. Each device may be formed from two parts. A first part may be provided with components such as a display, a touch screen, a cover glass, and a frame. A second part may be provided with a plastic housing, circuit boards containing electrical components, and a bezel. Engagement members may be connected to the first and second parts. The engagement members may be formed from metal clips with holes and springs with flexible spring prongs that mate with the holes in the clips. The metal clips may be welded to frame struts on the frame and the springs may be welded to the bezel. Hard stop structures may be used to vertically align the first and second parts. A frame in the device may have an integral gasket.

A housing includes a main housing part with an opening as well as a covering device for the opening. The covering device has a first cover part, which at least substantially covers the opening and a second cover part which is separate from the first cover part, bears at least in certain regions against the first cover part and has at least one clearance or aperture in the region of the opening. The second cover part is fastened or supported at the main housing part, in particular in the region of a periphery of the main housing part that extends or runs around the opening. The weight of the covering device is therefore low and yet a high level of stability and sealing in relation to fluids is provided.

Embodiments include a protective cover for a control module mounted to a vehicle surface using attachment mechanisms that extend perpendicularly from the vehicle surface. The protective cover comprises a rigid top portion having a top surface and four sidewalls configured to cover the control module and engage the vehicle surface. The protective cover also comprises a plurality of insets molded into at least two of the sidewalls, each inset configured to receive a respective attachment mechanism. Embodiments also include an apparatus for protecting a control module mounted to a vehicular surface using a plurality of attachment mechanisms. The apparatus comprises a rigid top structure configured to completely cover the control module and a flexible gasket coupled to a bottom edge of the top structure and configured to removably engage the vehicular surface surrounding the control module in a fluid-tight seal.

An electronic device and/or a method of sealing said device are configured for ease of installation and use. The electronic device has a housing having a recess, a cover concealing the recess and having walls extending circumferentially around the cover and having a channel formed in the outer surface thereof, and at least two through-holes formed through the channel, and an O-ring having a body with at least two tethers each of which passes through a respective hole in the cover.

A power supply box includes a box body, and a box cover is fitted on the box body. The box boy is internally provided with a first inner cavity and a second inner cavity. The first inner cavity is internally provided with a potentiometer. An adjuster of the potentiometer passes through a cavity wall and is located in the second inner cavity. The first inner cavity and the second inner cavity are separated by a vertical partition plate. The second inner cavity is partitioned into a first storage cavity and a second storage cavity through a transverse partition plate. The two ends of the vertical partition plate are provided with a first open slot and a second open slot, respectively. The first inner cavity communicates with the first storage cavity through the first open slot. The first inner cavity communicates with the second storage cavity through the second open slot.
