Abstract: A conductor connector assembly for connecting a ground conductor or the like to a U-shaped top hat rail, including a first sheet metal member (1) arranged for seated engagement transversely across the outwardly directed flange portions at the free ends of the legs of the top hat rail, a second sheet metal member (2) adjacent the first member and including at each end a hook portion (16) adapted to extend below the associated flange portion, and a screw device (3) for displacing the second member upwardly relative to the first member, thereby to clamp the rail flange portions between the first and second sheet metal members. A guide arrangement is provided for guiding the members for vertical movement relative to each other.

Abstract: An indicia-bearing attachment for electrical conductors includes a hollow generally U-shaped housing having a horizontal top wall and a pair of downwardly-depending side walls, thereby to define an open-ended chamber for longitudinally receiving at either end one end of the conductor depending on the orientation of the housing for proper reading of the indicia. In order to maintain the conductor in the chamber adjacent the horizontal top wall, a T-shaped clamp member is pivotally connected between the lower ends of the side walls, two arms of the clamp member being horizontal and colinearly arranged longitudinally in the chamber, and a third arm being vertical and joined to the adjacent ends of the horizontal arms.

Abstract: A modular terminal arrangement for connecting a conductor to a conductive cross bar (6), including a housing (1) formed of insulating material and arranged to transversely receive the cross bar, the housing including a terminal (2) adapted for connection with the conductor, a bus bar (4) connected at one end with the terminal and extending at its other end adjacent the cross bar, and a bridging member (7) adapted to connect the other end of the bus bar with the cross bar. The bridging member includes a pair of parallel spaced leg portions, the bridging member being displaceable between a connecting position in which the leg portions electrically engage the cross rail and extend at their free extremities in electrical engagement within an opening contained in the cross bar other end, and a disengaged position in which the leg portions are isolated from the bus bar.

Abstract: A hollow generally tubular female electrical connector is formed from a sheet metal blank to define a body member having a rectangular cross-sectional configuration including opposed pairs of side walls, characterized by the formation of two pairs of opposed inwardly-extending contact tongues that are arranged in longitudinally spaced relation for successive engagement by a male connector, whereby two different longitudinally-spaced contact planes are provided to afford reliable safe electrical contact with the male connector. Preferably, the contact tongues of one pair are formed from body side walls that are orthogonally arranged relative to the side walls from which the other pair of contact tongues are formed, whereby the pairs of contact tongues are arranged at 90.degree. relative to each other.

Abstract: An electrical connector (2) is adapted at its forward end for insertion from the rear forwardly within a through opening (10) contained in a base member (1). A snap fastener retaining arrangement including a pair of resiliently outwardly biased hook members (6) on opposite sides of the connector is adapted to automatically engage corresponding shoulders on the base member when the connector has been inserted to a given position within the base member opening. The connector is thus releasably retained in position, whereupon the connector may be rigidly fastened to the base member by second fastener devices (4) operable from the front of the base member. Upon disconnection of the second fastener devices, the hook members may be manually compressed inwardly toward the connector to release the snap fastener retaining arrangement, whereupon the connector may be withdrawn from the base member opening.

Abstract: An electrical connector or terminal block (1) is adapted for mounting on a printed circuit board or the like (2) at a position at least partially concealing a luminous diode (3), the connector containing a light-conductive member (4) that extends from the luminous diode to an exposed surface (5) of the connector, thereby to present a visible indication of the state of operation of the diode.

Abstract: An initiator terminal block for connecting a plurality of initiators with an electric power source, on the one hand, and with signal receivers, on the other hand, includes a plurality of terminal units each having a plurality of connecting locations arranged in three tiers situated above one another, each of the lower two tiers of each of the terminal units having only a single one of the connecting locations while the uppermost one of the tiers of each of the terminal units has two of the connecting locations that are electrically interconnected and are to be respectively electrically connected with the respective initiator and the respective signal receiver.

Abstract: An arrangement for clamping an electric conductor includes a clamping cage having a threaded bore centered on a central axis. A clamping screw is received in the threaded bore for threading in and out along a predetermined path centered on the central axis. An insertion receptacle for the electric conductor is accommodated in the clamping cage and extends substantially parallel to the central axis. A pressure member is mounted in the clamping cage for pivoting about a pivot axis out of and back into an open position thereof and extends into the predetermined path. A spring urges the pressure member toward its open position. The spring is an integral unitary portion of the clamping cage and extends from an outer contour of the clamping cage towards the pressure member.

Abstract: An electrical connector includes a clamping device having a clamping member for receiving a conductor and a clamping bolt, and a busbar. The end of the busbar is formed with a bend-over portion which is insertable into the clamping device together with the end of the conductor, overlapping that bend-over portion, from the same side of the clamping device.
