The connector comprises a male half and a female half and an annular electrical spring contact member which functions to provide continuous annular outer conductor electrical contact and RFI suppression. The annular spring member provides continuous annular outer conductor contact between facing surfaces at said male and female surfaces even during slight conductor misalignment. The spring is retained on said female member by a groove adjacent the outer end thereof, the outer end thereof is tapered away from a collar defining the outer end of the groove towards its axis, and the male member is at least 5% larger in diameter than the diameter of said female member adjacent the collar and said spring member extends at least 5% beyond the diameter of said collar.
Abstract: An insulation displacement connector comprises an insulative material body in which is a generally tubular metal contact member. This includes two at least part-cylindrical shell members of which one is a floating shell member and extends circumferentially cantilever fashion from a root generatrix. It is elastically deformable in the radial direction relative to this root generatrix. Respective inner and outer lips on the shell member define a slit extending around at least part of the circumference of the contact member. A barrel member rotatable about an axis of the connector forces an electrical conductor into the slit. At least in an unstressed condition of the connector, there is peripheral clearance between the floating shell member and the insulative material body.

Abstract: Apparatus is described for providing an electrical conduction path between two contact locations rotatable one with respect to the other. A flat ribbon cable having at least two electrical conductors and being wound in the manner of a spring, is firmly attached at its respective ends to the contact locations. To protect the flat ribbon cable from kinking and mechanical damage at each of such ends, each end portion thereof is folded across an immediately adjacent portion and a stabilizer connection assembly is positioned to extend about both such portions. Each such assembly is comprised of a protective sheath of flexible insulating material positioned closely about the folded end portion; an angular attachment of molded insulating material, including a clamping segment and a ribbon-shaped, sheath segment extending at an angle one to the other; and a means for locking the clamping segment in a compressed condition.
Abstract: A two part cylindrical connector having resilient collet fingers on one connector engagable with a cylindrical ridge on the other connector are disclosed. An outer shiftable sleeve secures the collet fingers in engagement with the cylindrical ridge when the shiftable sleeve is in an extended position. The shiftable sleeve is spring loaded relative to an inner core. The shiftable sleeve is assembled to the inner core with the spring between inner core and the shiftable sleeve. The inner core is then rotated relative to the inner core until anti-rotation surfaces on the interior of the shiftable sleeve and the exterior of the inner core engage to prevent further rotation. When these anti-rotation members engage, the springs are positioned so that they are confined between the shiftable sleeve and the inner core.
Abstract: A transition block for interconnecting flat undercarpet power cable to round conductor power cable has stackable terminal blocks each having an electrical terminal mounted therein. The conductors of the multiconductor power cable can be separated and folded such that each cable is vertically aligned with the other. Insertion of the cable into the terminal blocks and forcing the terminal blocks together causes an insulation displacement portion within the terminal block to pierce the insulation of the flat cable. A poke through type terminal is mounted adjacent to, and electrically continuous with, the insulation displacement portion for electrically interconnecting flat cable to round cable. The assembled terminal blocks are profiled for installation within the standard wall mounted junction box.
Abstract: Disclosed herein is a connector which comprises a female housing and a male housing to be fitted to said female housing for electrical connection therebetween.
