A connector assembly includes a housing having a flange along a circumferential direction, the flange has a groove spaced radially from the housing, and a sealing element disposed in the groove and forming a seal between the flange and a panel that has an opening receiving the housing. The sealing element is pressed against the panel when the housing partially passes through the opening of the panel.

An electrical connector includes a connector housing having a base, a flange, and a plug. The connector housing has a contact channel holding a contact. The electrical connector includes a latch member integral with the connector housing and located within the flange. The latch member includes a deflectable latch arm and a latching finger extending from the latch arm. The plug is configured to be inserted into a panel opening of the panel in a loading direction. The connector housing is movable laterally relative to the panel in a latching direction to a latched position. The plug is movable in the panel opening in the latching direction. The latching finger engages an inner edge of the panel opening when the housing is in the latched position to hold the connector housing in the latched position.

A charging/discharging apparatus includes a base; a fixing base that is fixed and provided on the base; and a cover plate, wherein the fixing base includes an end plate; a connection member formed by extending from the end plate to the base and connected with the base; an opening provided on the end plate to perform charging and discharging; and an accommodation space formed by the connection member being recessed or formed by being surrounded by the connection member and the base, the cover plate is formed in an arch-shaped structure or a bending surface structure and includes an accommodation state in which the end plate is exposed and a covering state in which the end plate is covered, and when the cover plate is in the accommodation state, an end of the cover state which is close to the base is provided to be directed to the accommodation space.

A power outlet, and associated method, for an electrical power supply strip. The power outlet includes a housing, an electrical connection for receiving first electrical power type, electrical components to change the first electrical power type to a second electrical power type, and a connection interface to supplying the second electrical power type. The power outlet housing has a body with a shape that corresponds to a shaped aperture of a main housing of the strip. A front portion of the power outlet housing is larger than the shaped aperture. An elastically deformable arm extends from the body and deforms as the arm passes through the shaped aperture of the main housing. An engagement portion of the arm retains the power outlet housing relative to the main housing.

A shelving system having a detached power supply apparatus includes at least a hollow vertical shelf rail, at least a bus bar inserted into the vertical shelf rail, and at least a detached power supply apparatus inserted in the vertical shelf rail and electrically connected to the bus bar. Each of the vertical shelf rails includes at least a punched hole, and two locating protrudes. Each of the bus bar includes a slot, and two current conductors. The slot includes a carrier surface, and a track abutting surface. Each of the detached power supply apparatus passes through the punched hole and is inserted between the carrier surface and the track abutting surface. Each of the detached power supply apparatus includes two push-in resilient ball head plungers, a receiving surface, an abutting surface, and two reeds. The abutting surface is engaging with the track abutting surface.

A modularly expandable enclosure including a top end plate, a bottom end plate, and one or more elongated tray modules. The top end plate, the bottom end plate and the tray modules define an interior space of the enclosure. Opposite vertical ends of each tray module define an upper end connecting portion and a lower end connecting portion. The upper end connecting portion is configured for engagement with the top end plate and further configured for engagement with a lower end connecting portion of a vertically upwardly adjacent module tray. The lower end connecting portion is configured for engagement with the bottom end plate and further configured for engagement with an upper end connecting portion of a vertically downwardly adjacent tray module.

A telecommunications panel has various features for removably mounting patching devices to the panel. The telecommunications panel includes mounting flanges and ramp elements for facilitating mounting and removal of patching devices. The ramp element is associated with a receptacle opening of the panel and configured to contact a flexible latch of the patching device and depress the flexible latch as the patching device is received in the receptacle opening.

An electrical outlet device includes water-resistant components to prevent the ingress of water to electrical components. One example includes a faceplate having a front surface, an outer edge extending around the front surface, and a first outlet opening extending through the front surface. A water-resistant seal is connected to the front surface of the faceplate. The seal has a first slit aligned with the first opening, a first flap adjacent the slit, and a second flap adjacent the slit. The first flap and the second flap are resiliently biased to a closed position and are moveable upon insertion of a plug.

Housing for a module outlet includes first housing with a first opening configured to receive a body of a first outlet core so that a lip area of the first outlet core prevents the first outlet core from travelling through the first opening. A tab is configured to hold the body of the first outlet core secure within the first opening. A dovetail tongue is configured for sliding into a dovetail groove of a second module housing so as to secure the first module housing to the second module housing.

A power transfer system includes a port panel assembly including a port panel, a locating pocket formed in the port panel, locking ports arranged in the locating pocket, and terminal assemblies attached to a rear side of the locating pocket and having conductive terminals, and a power transfer assembly having a transfer housing with access ports and terminal retainers, latches housed in the transfer housing to engage the locking ports, a spring arranged between the latches and pressing the latches to protrude outwardly from the transfer housing through the access ports, and connection members arranged in the terminal retainer and adapted be connected to an electric device. When the power transfer assembly is inserted into the port panel assembly, tip portions of the latches are inserted into the locking ports to be secured to the port panel assembly, and the connection members contact the conductive terminals of the port panel.
