Abstract: The entire outer surface of a ground rod, including its pointed end portion, has a continuous and uniform electroplated coating. The rod has a blunt end portion shaped to minimize mushrooming when it is hammered for driving the rod into the ground. Jets of plating solution directed against the rod produce swirling motion of plating solution around the rod while it moves longitudinally through a plating bath. Uniformity of the plated coating may be enhanced by rotating the rod during longitudinal movement through the plating bath.

Abstract: The present device provides a terminal mounted on the surface of a printed circuit board and, more particularly, to a terminal used for reliably contacting the electrodes of a battery. In a terminal comprising a housing and a plurality of spring contacts mounted in the housing, the curved parts of the spring sections of the spring contacts extend externally from one surface of the housing in different arrangement. Since the positions of the curved parts are different, the spring actions of the contacts against the contact target members are not localized. Even if the shape of the contact target members varies largely, these members can be held reliably.

Abstract: An improved electrical ceiling box including a top portion bounded by a peripheral side portion, with a pair of diametrically opposed ear lugs rigidly secured to the side portion. Each ear lug has a pair of ears integrally formed therewith extending inwardly into the interior cavity of the box. A first ear fits within a recess formed in the bottom edge of the box, while a second ear extends through a slot formed in the side portion of the box. The second ear has a mounting hole formed therein adapted for threaded engagement with a self-tapping screw, while the first ear has a receiving hole formed therethrough for supporting the distal end of the screw. In a preferred embodiment, the box has a substantially hexagonal configuration. In an alternative embodiment, the box has a circular configuration and is shallower, thereby eliminating the need for a pair of slots for receiving the first ears.

Abstract: A single-sided, straddle mount printed circuit board edge connector positively mechanically locks the connector to the circuit board using a plurality of gripper arm assemblies spaced along the connector housing. The gripper arm assemblies each include an upper and lower gripper arm defining therebetween a printed circuit board receiving space. The gripper arm assemblies positively mechanically lock the printed circuit board to the connector without the use of through holes and screws. The connector overcomes the disadvantages of connector tilt problems, manufacturability and provides for simplicity in assembling the connector and printed circuit board.

Abstract: A bond bar assembly spans an electrical cable splice. The bond bar assembly includes a conductive bond bar having opposed ends and a longitudinal central extent which spans the cable splice. Each end of the bond bar has a generally planar surface for engagement with the cable. A radially contractable clamping member is securable about the cable and about the planar surface of each bond bar end for securing the bond bar ends to the cable. The planar surface of each bond bar end includes a deflectable jacket skiving member which is deflectably movable from a first position in non-skiving engagement with the jacket of the cable to a second position in skiving engagement with the cable jacket upon the radial contraction of the clamping member. Such arrangement positionally confines and secures the bond bar with respect to the cable.

Abstract: An electrical connector housing includes a deformable contact retention plate for accommodating the tails of electrical contacts. Contact tails are supported within slots in the retention plate both at a closed end of the slot as well as at an intermediate location therealong. The contact retention plate may be deformed about the contacts so as to captively retain the contact tails within the slots. Such deformation may be achieved by ultrasonically swaging the plastic forming the contact retention plate about the contact tails.
