An RF connector has an insulator that allows water to pass through it away from any solder connections but blocks the ingress of water from the outside into the RF connector's solder joints. The insulator comprises a check valve means. The check valve means may be disposed out the outer cylindrical surface of the insulator and may have one or more Tesla valve structures.

A rotary electrical plug is provided. The rotary electrical plug includes a rotary base, a first insert, a second insert, a first conductive connection lug, and a second conductive connection lug. The first insert and the second insert are circumferentially limited and mounted on the rotary base, the first insert is provided with a first conductive circular portion, the second conductive connection lug is provided with a second conductive circular portion, and the first conductive circular portion, the second conductive circular portion, and the rotary base are coaxial with each other. The first conductive connection lug is electrically connected to the first insert via the first conductive circular portion, and the second conductive connection lug is electrically connected to the second insert via the second conductive circular portion.

A device may include a housing including a face plate. A device may include a plurality of sensing cores each configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity, wherein the current flow direction is parallel to the face plate.

The present application relates to a coaxial connector, intended to transmit radio frequency RF signals, of longitudinal axis X, including: an outer contact forming a body/casing, which at least one of its ends is slotted defining contact petals, a central contact and, at least one electrical insulating solid structure coaxially interposed between the central contact and the outer contact, which is mechanically retained in the outer contact and in which the central contact is mechanically retained, at least one of the free end of the electrical insulating solid structure having an elasticity of its periphery, at the level of the petals of the outer contact, which is increased compared to the rest of the electrical insulating solid structure.

A connector assembly includes a first connector and a second connector, in which the first connector includes: a first signal terminal; a first fixed part which fixes a first part of the first signal terminal; a first terminal which fixes the first signal terminal with the first fixed part held therebetween; a second fixed part which fixes a second part of the first signal terminal; and a second terminal inside which the first signal terminal is fixed with the second fixed part held therebetween, the second connector includes: a second signal terminal; a third fixed part which fixes the second signal terminal; and a third terminal which fixes the second signal terminal with the third fixed part held therebetween, and since a diameter of the bending part is smaller than a diameter of the second part, the second fixed part is caught on the second part and is retained.

A housing includes a dielectric body having a plurality of terminal receiving passageways extending through the dielectric body along a longitudinal direction. The dielectric body has a latch section in which a plurality of walls of the dielectric body that each define one of the terminal receiving passageways are separated from one another by a gap in a lateral direction perpendicular to the longitudinal direction. The walls in the latch section are deflectable toward one another in the lateral direction into the gap.

An AC power transfer module includes at least one adapter and at least one grabber, the AC power transfer module operable to enable uninterrupted delivery of power to a demand unit. The adapter is configured to plug into an original power source and supply electricity to the demand unit which is plugged into the adapter, and the grabber is configured to plug into the adapter and separately engage with a transfer power source. The adapter includes a mechanical switch that is actuated by engagement of the adapter with the grabber to switch the supply of power from the original power source to the transfer power source, whereby the AC power transfer module enables switching to a new power supply without power disruption to the demand unit.

A plug connector for transmitting high-frequency signals includes an inner-conductor and an outer-conductor contact, and an insulator arranged therebetween. A receptacle is formed by the outer-conductor contact and is configured to receive a mating plug connector to establish a connection. A catch basket is: formed by the outer-conductor contact, and/or arranged in the receptacle and is configured to produce contacting between the outer-conductor contact and the mating plug connector in a connected state of the plug connector and the mating plug connector. The catch basket comprises a main body and a spring element having a first and second free end. The spring element is connected to the main body by torsion bridges such that the spring element is configured to tilt when the plug connector and mating plug connector are being connected, and such that the free ends are configured to press against the mating plug connector.

An extendible wall outlet system is disclosed. The system includes an outlet box, an extension box attached to the outlet box and having a passage between the two boxes, a flexible electrical cord having an extendible receptacle on a free first end and electrically coupled to a power source at an opposing second end, and a spooling device positioned within the extension box and configured for retaining the flexible cord in a coiled manner. The extendible receptacle is retained in a position in the outlet box, is extendible from the outlet box when pulled outward from the outlet box, and the flexible electrical cord uncoils from the spooling device as the receptacle is pulled.

A seal configured to provide an enhanced seal between a connector and an interface port may include a seal portion that includes a separation portion and a sealing portion. The sealing portion may include a forward sealing portion and a rearward sealing portion. The sealing portion may be structurally configured to cooperate with a seal engaging port portion of an interface port and a seal engaging connector portion of a connector so as to provide a sealed connection portion between the sealing engaging port portion and the seal engaging connector portion even when the forward sealing portion is separated at the separation portion so as to maintain the sealed connection between the seal engaging port portion and the seal engaging connector portion and provide an enhanced port-connector seal even when the forward sealing portion no longer provides a seal between the connector and the interface port.
