Abstract: An electrical connector assembly (10) has a drawn solderable insert (42) received in a mounting aperture (28) of an electrical connector housing (12) and secured therein by a shell (30). The insert (42) has an internally threaded (52) hollow tubular shank (44). Flange means (46) on the insert (42) are received in a recess (54) in either a shell means or the housing (12) and cooperates therewith to prevent the insert (42) from rotating. The flange means (46) are thicker than the depth of the recess (54) to assure electrical continuity between the insert (42) and the shell (30). In a first embodiment, the shank (44) extends beyond the connector housing (12) to a closed end (50) that may be tapered. An alternate embodiment insert (42') has an open end. Yet another alternate embodiment insert (42") has spring means (74,76) that cooperate with insert receiving aperture (60) to secure connector assembly (10) to printed circuit board (62). A further alternate embodiment insert has a spacer means (102) thereon.

Abstract: A knife for cutting cartons comprises a movable blade carrier, and blade, mounted in a stepped guide for positive blade location at any of a plurality of selected locations, within a handle having an extended area lip feeler adjacent a handle opening such that the blade may be presented through said opening in any of a plurality of lengths corresponding essentially to the thickness or thinness of a carton wall so that the knife cuts the carton and not its contents, consistent with safety for the operator, economy of manufacture and use and compactness.

Abstract: The continuity tester comprises means utilizing existing circuits for testing continuity together with a further integrated subassembly providing a completely self-contained circuit for testing stretches of wire unrelated to any circuit.
