Methods and apparatus for an assembly including a circuit card coupled to an alignment bracket having a bracket mounting hole with an interposer board having a front and back connectors and a mounting hole. The front connector is mated with the circuit card and the back connector is configured and positioned to mate with a test connector of a unit under test (UUT). An alignment plate has a plate mounting hole. First and second alignment pins may be rotatably engaged to position the connectors in relation to the alignment plate.

A clamping screw device has a clamping screw extending in an axial direction and including a screw head that is rotatable, a screw body, and a screw foot. The clamping screw device has an electrical insulation on an outside of the screw head. The electrical insulation accommodates an electromagnetic shielding and/or a seal.

A connector keying system includes at least one keying device including a flange portion and a keying portion. The flange portion includes a front surface and a back surface. Each of the front surface and the back surface extend substantially parallel to a flange plane. The flange portion further includes a connector aperture extending through the flange portion. The keying portion extends around an aperture perimeter of the connector aperture and projects outward from the flange portion. The keying portion includes and extends between a first key end located at the front surface and a second key end opposite the first key end. The second key end defines a keying perimeter about the connector aperture. The keying portion has a height between the first key end and the second key end and the height is inconsistent between the first key end and the second key end along the keying perimeter.

A heavy-duty, harsh environment coaxial connector assembly includes a mounting shell connector including a cylindrical body and an electrically conductive mounting flange extending from the cylindrical body, a plurality of mounting apertures formed in the flange to support the mounting shell connector via a plurality of fasteners extending through the respective mounting apertures, and wherein each of the plurality of fasteners is electrically isolated from the mounting flange.

A connector according to the present invention includes a terminal fitting, a housing component which houses the terminal fitting, and an annular water cut-off member which is assembled to an outer peripheral surface of the fitting portion of the housing component and brings an outer peripheral side of the water cut-off member into close contact with an inner peripheral surface of a mating fitting portion at a fitting completion position.

A cable connector (100-900) for connecting an electrical cable, the electrical cable including a cable conductor having a terminal end portion, the terminal end portion having an end face, includes an electrically conductive connector body (110), a conductor bore (102) in the connector body (110), a securing mechanism, and a contact mechanism (141). The connector bore (102) defines a conductor bore axis and is configured to receive the terminal end portion of the cable conductor along the conductor bore axis. The securing mechanism is operable to clamp onto the terminal end portion. The contact mechanism (141) includes a pressure member (170A, 170B), an electrical contact surface, and a drive mechanism (151). The drive mechanism (151) is selectively operable to drive the pressure member (170A, 170B) to force the electrical contact surface against the end face of the cable conductor.

A connector includes a retaining member that is held by the terminal housing portion at an assembly completed position to the terminal housing portion to lock movement of the terminal fitting with respect to the terminal housing portion in a terminal extraction direction opposite the terminal insertion direction at the assembly completed position are provided. The retaining member includes a terminal locking portion disposed facing a locked portion of the terminal fitting at the assembly completed position in the terminal extraction direction to lock movement of the locked portion in the terminal extraction direction. The terminal fitting includes a retainer housing portion that accommodates the terminal locking portion of the retaining member at the assembly completed position and allows relative movement of the terminal fitting in the alignment direction with respect to the terminal locking portion.

An electronic device having a detachable memory is provided with a docking connector, and includes a device body and a memory. The device body has an accommodating slot and a stopping portion provided corresponding to the accommodating slot, and the stopping portion and the accommodating slot jointly form a displacement space in between. The memory is provided with a connector and a protruding stopped portion. When the memory is accommodated in the accommodating slot, the stopped portion is moved along into the displacement space and is stopped by the stopping portion, and the connector is docked with the docking connector. Thus, the memory is provided with an anti-misplugging effect.

An electrical apparatus disclosed herein includes first/second electrical units configured to be fixed to each other. The first electrical unit has a first surface including a connector. The second electrical unit has a second surface facing the first surface of the first electrical unit. The second surface includes a socket configured to fit with the connector. One of the first and second electrical units includes a stud bolt extending toward the other of the first electrical unit and the second electrical unit, and the other of the first and second electrical units includes a bolt hole through which the stud bolt is configured to pass. When the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a bolt-hole distance from the stud bolt to the bolt hole is shorter than a connector-socket distance from the connector to the socket.

An electrical connection unit for a battery pack includes a busbar having a first hole therein, a top surface and a bottom surface, an annular bushing having a top end abutting the bottom surface, a bottom end opposed to the top end and a bore hole therein registered with the first hole, a busbar cage secured to the busbar and retaining the annular bushing in abutment with the busbar, the busbar cage having a cavity therein above the top surface, and a fastener having a head portion captured within the cavity and a shank portion extending through the first hole. The annular bushing may include one or more indents formed on an outer surface thereof, and the busbar cage may include a plurality of fingers extending along the outer surface and interfacing with the one or more indents. Each finger may include a protrusion configured to rest within an indent.
