An electrical unit and method of assembly that includes a base housing having a plurality of sides and an opening in one of the sides configured to receive a wire therethrough, and a cover configured to mate with the base housing, defining an internal chamber therebetween. A power distribution box is disposed within the internal chamber, at least one electrical connector is disposed at least partially within the internal chamber, operatively engaging the power distribution box, and extending through the opening, and a universal sealing plate that is selectively mountable on each side of the power distribution box and mounted to align with and seal against sides of the opening and at least a portion of the electric connector extending through the opening.

A junction box mountable on a roof surface, comprising a housing unit and an enclosing unit, the housing unit and enclosing unit combining to form a waterproof assembly. The housing unit is mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in a bottom surface of the housing unit to create a waterproofing zone inside the housing unit. At least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

A novel weatherproof electrical component enclosure incorporates swappable internal module configurations for several types of network devices, wherein each internal module embodies standardized dimensions and standardized attachment elements for seamless internal device swap in-and-out compatibilities within the same weatherproof enclosure. Examples of novel swappable internal modules for the novel weatherproof electrical component enclosure include a fanned Power-over-Ethernet (PoE) switch, a fan-less PoE switch, a network router, and a wireless base station, all of which are simply swappable in and out of the weatherproof enclosure. The novel weatherproof electrical component enclosure also uniquely incorporates a customer's component hotel space as a weatherproof storage of customer-specific private accessory devices, in addition to housing factory-packaged original equipment which the weatherproof electrical component enclosure is originally designed to encase. The swappable modularity of internal components in the weatherproof enclosure reduces outdoor network equipment design constraints, manufacturing costs, and network implementation and maintenance costs.

A cover to temporarily deactivate a smoke detector. The cover is placed over a smoke detector to temporarily prevent smoke detection and removed when the smoke producing activity has been completed.

A sealing system for an electronics enclosure includes an enclosure having a first enclosure half and a second enclosure half, the first enclosure half including at least one sidewall, a multi-lip radial sealing member having a plurality of lip elements, the lip elements extending perpendicularly to the side wall, the radial sealing member being positioned between the first enclosure half and the second enclosure half such that the radial sealing member remains flush against the enclosure, and the lip elements form continuous points of contact around the perimeter of the enclosure.

A multipurpose wire connection device includes a base plate, a conductive plate, a wire fixation screw, a fireproof box, a support, and a dustpan-shaped housing. The support is disposed on the base plate. The fireproof box includes a rear panel, a bottom panel, two side panels, and an inserted plate. The wire fixation screw is mounted on the conductive plate. The housing is fixed on the bottom plate by a housing fixing screw. The multipurpose wire connection device prevents sparking and red burning of a ground screw when lightning current passes therein, due to corroded contact in long-term exposure to wind and rain. It avoids fire and explosion accidents. It avoids screw corrosion and facilitates ground resistance measurement. The multipurpose wire connection device can also be used for electrical relay, division, and branching. It prevents fire, explosion, rain intrusion, and rust development. It is easy to disassemble.

An electrical connection box applied to a wire harness includes a casing that includes an accommodating space that is formed therein and that accommodates an electronic component, and a guiding space that is partitioned horizontally lateral to the accommodating space therein via a partition wall, and that extends in a vertical direction and guides water entered therein to a vertically downside. The casing includes a water-preventing rib that is provided in the guiding space, and that guides water guided to the vertically downside in the guiding space, in a direction of avoiding from an avoidance target portion that is positioned vertically below the guiding space.

A watertight electrical compartment for use in an irrigation device can include a compartment body with a chamber, a sealing section mounted with one or more sealing rings, and external threads. A sealing cap mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap and can have internal threads to be screwed onto the external threads of the compartment body. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

A post for holding an electrical device includes a body having an interior volume to hold the electrical device and a cover that is slidable on the body between an open position to access the volume and a closed position covering the volume.

Disclosed is a while-in-use cover assembly for an electric wire box, having: a base having a front surface and a bottom surface; a lid that selectively covers the base front surface, wherein a first geometric shape is formed by a top profile of the lid, and the while-in-use cover assembly is confined to the first geometric shape when closed; and a ball-joint connecting the lid and the base, wherein the lid can pivot relative to the base, about the ball-joint, for positioning the lid against the base and away from the base, wherein: when the lid is positioned against the base the while-in-use cover assembly is closed; and when the lid is positioned away from the base, the while-in-use cover assembly is opened.
