An interface device that includes a plastic part including at least one through-opening in a longitudinal direction, the plastic part being adapted to be fixed in an airtight manner into an opening in the wall. At least one metal shaft is arranged and fixed in the through-opening. The metal shaft has a connection element at each longitudinal end. The metal shaft is configured to provide electric connectivity from one side of the wall to the other in a fixed position of the interface device. At least one fixing element is adapted to fix the plastic part to the wall.

An electrical connector assembly comprises a header and a backing plate attachable thereto. The header includes a plug portion for connecting to a complementary mating connector, and a base having a plurality of mounting through holes for fixing the header to a mounting surface. The backing plate includes a plurality of mounting elements corresponding in location to the plurality of mounting holes of the header for fixing the backing plate to the header on an underside of the mounting surface, and a central opening corresponding in location to the plug portion of the header with the backing plate fixed to the header.

A Dry-Mate Connector System (DMCS) is capable of a direct and convenient connection/disconnection of standardized Commercial Off-The Shelf (COTS)-compatible data communication cables and connectors with submersible electronic equipment for transmission of data/signals/power therebetween, and is suitable for indefinite submersion, as well as adaptable to full ocean depth. DMCS is equipped with sealing elements, a keying/alignment mechanism for proper alignment of COTS connectors for mating the portions, a locking mechanism to ensure the portions remain locked and pressure sealed, and a dummy plug for sealing the connector when not in use. Functional dummy plugs are contemplated to broaden the functionality.

A cable connector and method includes a female connector and a male connector. The male connector includes a threaded portion insertable through a standard Knock Out (KO) of a panel unit and a nut threaded onto the threaded portion to retain the male connector through the KO. The female connector including a threaded cap engaging the threaded portion to connect the female connector to the male connector.

Provided is a relay connector including: a housing body, the housing body includes a first and a second protruding portion protruding outward from an outer surface of the housing body, the first protruding portion includes a first contact surface orthogonal to a first direction, and the first contact surface is provided in such a manner that at least a part of the first contact surface is visible as the relay connector is viewed from the first contact surface side along the first direction, and the second protruding portion includes a second contact surface orthogonal to a second direction perpendicular to the first direction, and the second contact surface is provided in such a manner that at least a part of the second contact surface is visible as the relay connector is viewed from the second contact surface side along the second direction.

A bulkhead connector comprises a connector housing, a nut member and a self-locking structure. The nut member is removably fitted to the connector housing to secure the bulkhead connector to a target plate body. An outer surface of the connector housing is formed with an outer thread, and an inner surface of the nut member is formed with an inner thread.
