An adaptor plate includes a front plate that is configured to span across at least a portion of a front of an electrical junction box and includes one or more adaptor plate mounting features configured to align with corresponding mounting features of the electrical junction box. A DIN rail engagement portion extends backward from the front plate (and into the junction box) and is configured to fit at least partially into an elongated DIN rail mounting recess of a DIN rail device. In some cases, a first mounting slot is disposed within a first side of the DIN rail engagement portion for receiving a first mounting latch of the DIN rail device, and a second mounting slot is disposed within a second side of the DIN rail engagement portion for receiving a second mounting latch of the DIN rail device.

Systems, methods, and articles of manufacture for modular junction boxes. Some modular junction boxes may, for example, comprise integral mating elements that are secured in position by mounting of one or more adapters, connectors, or fittings.

A protective housing for a central electrical system deployed within an electric vehicle is described. The protective housing features a first housing layer, a second housing layer and a third housing layer. The first housing layer is configured to support and protect one or more power distribution units responsible for distributing high-voltage power to components within the electric vehicle. The second housing layer is positioned above the first housing layer, where the second housing layer is to support and protect a power charger that disseminates supplied input power to a high-voltage junction box for routing to the battery system of the vehicle. The third housing layer is positioned above the second housing layer, where the third housing layer is to support a high-voltage junction box that handles the routing of power between the distribution unit(s), the charger and the battery system.

A junction box includes a housing having a plurality of side wall portions, and a liquid detector including a first terminal portion and a second terminal portion. The junction box is disposed in a housing case housing a power storage module. The first terminal portion and the second terminal portion are directed toward a lower side of one of the side wall portions and drawn out from the inside of the housing to the outside of the housing.

A flush mountable electrical apparatus, according to an example, includes an electrical apparatus including a junction box having an open end, an electrical device positioned within the junction box, and a first cover plate to cover the open end of the junction box. The flush mountable electrical apparatus further includes a second cover plate attached to the first cover plate, and a mounting plate to be mounted over a recess in a mounting surface. The mounting plate includes a first opening sized to allow the electrical apparatus to be inserted through the first opening and into the recess. The second cover plate is configured to be attached to the mounting plate to secure the electrical apparatus in position within the recess.

Provided is a foldable emergency power box with a shaft structure allowing wires to penetrate through. A shaft assembly is arranged to connect two box bodies, so that the emergency power box may be of different structures to flexibly adapt to different installation scenarios; and a cavity is formed in the shaft assembly to allow connecting wires to penetrate through, so that a rotary structure is realized without exposing the internal connecting wires, and thus, the foldable emergency power box is safe and practical.

A selectively deployable cable management device for organizing cables includes a plurality of panels, the panels of which are selectively stackable into a stowed configuration so that a volume of the plurality of panels is minimized. The panels are selectively interconnectable to form a box. A power distribution device, such as a power strip, can be positioned in an interior space defined by the box. Each of a plurality of apertures is positioned in a front facet or respective opposed end facet of the box. The apertures vent the interior space and are used for extension of a power cable from the power distribution device to a source of electrical current and for insertion of a power cord extending to an electronic device to connect and operationally engage the electronic device to the power distribution device.

A tap-off box includes a latch that automatically secures the tap-off box to a busway upon insertion of a mast into the busway. The latch is in the form of a single spring-loaded member that latches onto a rail as the masthead is pushed into the busway. A push button actuated camming member pushes the latch away from the rail to enable the masthead to be withdrawn from the busway. The push button and camming member are independent of the mechanism that extends and retracts the contacts while the masthead is inserted and latched into the busway. The tap-off box may also include non-contact current monitoring sensors with voltage sensing inserts that an auxiliary breaker switch in applications other than a tap-off box, and an infrared emitting faceplate that can be adapted for monitoring a variety of breakers from outside the tap-off box.

A water-resistant element, adapted to an opining, comprising a deformable body, a first plate and a second plate is provided. The first plate is disposed at and against a first side of the deformable body. The second plate is disposed at and against a second side of the deformable body. When the deformable body is disposed in the opening, a relative displacement between the first plate and the second plate is used to change a shape of the deformable body such that the deformable body closely fits the opening in order to block moisture from entering into the opening. In addition, an external connection wire module comprising the water-resistant element, an antenna box module comprising the external connection wire module and a method of fixing the water-resistant element at a housing are also provided.

An electrical box assembly and cable connector are provided. The cable connector includes a connector housing and a cable retaining member that releasably secures an electrical cable within the connector housing. The electrical box assembly includes an electrical box and a cable connector. The electrical box assembly may also include a box separator.
