Apparatuses, systems, and methods for data and/or power transfer to and from an ocean bottom seismic node are described. In an embodiment, an autonomous seismic node is configured with a bulkhead connector assembly that may be coupled to a plug assembly for data and/or power transfer and a pressure cap assembly when utilized subsea. A plurality of pins may be located on the bulkhead assembly in a substantially flat contact surface to obtain an external electrical connection to the node. The pins on the bulkhead assembly may form a flat circuit with an external device, such as a plug assembly or pressure cap assembly. One or more external devices may be coupled to the pressure cap assembly and/or bulkhead connector for increased functionality to the node. A quick release assembly and/or locking ring may be utilized to fasten any external device to the bulkhead connector assembly.

An electrical pin and sleeve device is disclosed. The pin and sleeve device incorporating one or more features to facilitate easier assembly. For example, the pin and sleeve device may include an interrupted thread or a multi-start thread for coupling a first or main housing portion to a second or front housing portion of the device. In this manner, the outer housing can be assembled together with minimal number of turns to facilitate easier and faster assembly. Additionally, and/or alternatively, the front housing portion and the main housing portion may include a key such as, for example, a releasable lock (e.g., a spring plunger assembly) for indexing/indicating the proper rotational position of the front housing relative to the main housing to limit or prevent over-rotation. Additionally, and/or alternatively, a hollow O-ring may be positioned between the first and second housing portions.

A protective assembly provided with a hollow first cap with a first cavity configured to house a first connector and a second cap. The second cap has a hollow portion delimiting a second cavity configured to house a second connector to be connected to the first connector. The first cavity is shaped to match an outer casing of the hollow portion. The second cap penetrates into the first cavity in a sealed manner, in a connected mode, isolating the first cavity and the second cavity from an external environment.

A coupling (1) comprising: a first part (2) sized and shaped to fit through an orifice in a surface and having a mounting surface (5) for abutting against the surface, and comprising a body having a through bore (7); and a first connector part (13) having a termination (15) for at least one conductor, and a connection member (16) for each termination (15); and a second part (3) in threaded engagement with the first part (2), the second part comprising a body having a through bore (10) in communication with the through bore (7) of the first part (2); a second connector part (14) having a connection member (17) complementary to each connection member (16) of the first connector part (13) so that the connection members (16, 17) of the first (13) and second (14) connector parts can engage each other and a termination (19) for a conductor for each connection member (16) of the second connector part (3).

A connector includes a first housing, a second housing configured to be fitted to the first housing; a rotation member rotatably supported on the first housing; a lock arm including a lock part configured to lock with a lockable part of the first housing in a fitting completion position, an operation section configured to release the lock arm from a locked state, and a fulcrum part connected to an outer peripheral surface of the rotation member at a position between the lock part and the operation section, and configured to swing around the fulcrum part and to lock or release the lock arm by elastic deformation thereof; and a fitting detection member configured to detect a fitted state of the first housing and the second housing while being assembled to the rotation member and when moving in a locking direction from a temporally lock position to a fitting confirmation position.

An electrical connector includes a connector shell, a coupling nut, and an indicator surrounding the connector shell. The indicator includes a clamp member and a check member. The clamp member includes a ring and a coupling structure extending from the ring to the check member and coupling the ring to the check member. The indicator may assist a user in determining if the electrical connector is in a fully-mated state.

A ganged connector assembly includes: a plurality of coaxial connectors, each of the coaxial connectors connected with a respective coaxial cable extending rearwardly therefrom, each of the coaxial connectors including an inner contact and an outer body that is electrically separated from the inner contact; a shell having a plurality of cavities; and a plurality of rear bodies, each of the rear bodies encircling a respective outer body, each of the rear bodies mounted in a respective cavity of the shell. Each of the rear bodies includes a first locking feature. A second locking feature is located in each of the cavities and is fixed relative to the shell. The first and second locking features are configured such that rotation of a first of the plurality of rear bodies relative to the shell moves the first rear body between locked and unlocked positions, wherein in the locked position a respective first connector and respective first cable are secured with the shell within a respective cavity, and in the unlocked position the first connector and first cable can be removed from the shell without removing the remaining connectors and cables.
