An interface arrangement for an electric traction system of a vehicle comprises a stator housing of an electric traction motor of the electric traction system, a protective housing of a power electronics of the electric traction system and at least one contact plate of an electric interface of the electric traction motor reaching through the stator housing and the protective housing and a sealing element having the at least one contact plate reaching through the sealing element. An electric traction system for a vehicle, and a method for making a sealing element for an interface arrangement of an electric traction system of a vehicle are also provided.

An electrical connector includes: an insulative housing having a rear base and a front tongue; an upper and lower rows of contacts mounted in the insulative housing and exposed to the tongue; a shielding shell enclosing the insulative housing; and a sealing element sealing a junction between the insulative housing and the shielding shell; wherein the shielding shell includes a rear step located immediately adjacent the junction and a recess at a corner of the step, and the base of the insulative housing includes a step fitting the rear step of the shielding shell.

A dry mateable subsea electrical connector coupling, having a removable connector body adapted to couple a first connector part, terminated to a subsea cable or jumper, to a subsea sensor device, or to a subsea wet mateable connector part. The removable connector body is adapted to seal a chamber of the first connector part terminated to the subsea hose or jumper and to receive electrical conductors of the subsea sensor device or subsea wet mateable connector part. The removable connector body includes electrical conductors and fittings adapted to receive corresponding electrical conductors and fittings from the hose or jumper.

A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a hot-stick. A clamping member cooperates with a frame having an arm, and is selectively biasable by a user to translate the clamping member relative to the frame to clamp a conductor between the clamping member and arm. The lock-out cooperates with the clamping member to prevent the translation of the clamping member unless in the presence of an insulating tool such as a hot-stick.

A snap-in electrical receptacle comprising a housing including a plurality of sides, a face plate attached to the housing, at least one electrical outlet attached to the face plate, and at least one L-shaped member included in at least one of the plurality of sides, the L-shaped member including a shelf generally coplanar with the face plate and an inclined protrusion. The snap-in electrical receptacle can be installed without tools or extraneous fasteners, and may be configured with a multiple variety of electrical inlet ports and electrical outlets.

Tunable phase shifters and methods for using the same include a signal line; one or more grounding lines; one or more crossing lines below the signal line in proximity to the signal line and substantially perpendicular to a longitudinal direction of the signal line, where the crossing lines conform to the shape of the signal line along at least three surfaces of the signal line and where the crossing lines have a tunable capacitance; and an inductance return line below the crossing lines substantially parallel to the longitudinal direction of the signal line, where the inductance return line provides a tunable inductance.

A method for laying multiple conductors in a container may be provided. The method may comprise receiving the multiple conductors at a monitoring station; receiving the multiple conductors at a drive; and receiving the multiple conductors at the container.

An electrical connector comprises an outer shell, at least one pin, and an insulating seal. The outer shell includes at least one side wall defining a cavity and having an inner surface. The outer shell is formed from electrically conductive material. The pin is positioned within the cavity and is also formed from electrically conductive material. The insulating seal is configured to provide electrical isolation of the pin and fills the cavity between the inner surface of the side wall and the pin. The insulating seal is formed from glass doped with a transition metal oxide.
