Abstract: A parallelepiped housing is open on one side and has a face plate moveable toward and away from the rear wall. A movable support holding electrical contacts is provided to receive the blade of a plug. An articulated arm assembly having a free end extending inwardly and bendible on movement of the face plate rearwardly is mounted on the moveable support to occlude the contact in the absence of the insertion of the blade, or in the presence of a blade, to proceed through the hole in the blade and into a channel thereby locking the blade in the slot, or in the insertion of a foreign object to prevent movement of the moveable support. The housing includes electrical contact means fixedly located to the rear of the electrical contact for connection to a source of current.

Abstract: A single filament type wedge-base lamp has projections on opposite sides at opposite end portions of a flat base of the lamp, and the corresponding socket has a recess with clearance grooves corresponding in position to the projections. The socket for a double filament type wedge-base lamp has a recess without clearance grooves so that the single filament type wedge-base lamp, which has the projections thereon, is prevented from erroneously being inserted into the double-filament type lamp socket since the projections will interfere with the recess walls of the double-filament type lamp socket. If a double filament type lamp is inserted into the socket for a single filament type lamp, either one of the two filaments thereof will operate without posing a problem.

Abstract: A right-angle termination for a coaxial conductor is described, which has an access aperture that provides good access for soldering the inner conductor of the termination device to the inner conductor of a coaxial cable, and which enables rapid and easy closure of the access aperture. A sleeve is slideably mounted about the outer conductor of the termination device, to slide between an open position away from the access aperture, and a closed position over the access aperture.

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: A microminiature coaxial connector is described. 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: 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: A method and connector device for connecting insulated wire cable to another device is provided. The connector device includes a housing having an array of bifurcated connector disposed in a preselected pattern. The cable wires are completely stripped of the insulation at locations corresponding to the pattern of the connectors. The wires are then pushed into the connectors transversely to slidingly and frictionally engage the wires. The wires are pushed into this engagement by a cover which coacts with the housing to insulate the wires and their connectors.

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: 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: 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. The connector has a locking structure including a locking arm having a locking edge portion provided on one of the housings and a locking projection provided on the other housing. The locking arm is flexibly supported on either the female or male housing and the locking projection is provided so as to be locked with the locking edge portion when the female and male housings are properly fitted together. The locking projection is constructed so as to camber the locking arm when the male housing is inserted into the female housing, thereby causing a restoring force to be generated in the locking arm. Further, the locking structure includes a member for increasing the restoring force to secure the fitting between the locking edge portion and locking projection without increasing the force required to disengage the locking structure.

Abstract: A waterproof electrical connector. The waterproof electrical connector is comprised of a male connector housing and the female connector housing. The male connector housing has an annular enclosure around an outer periphery thereof to form an annular cavity therebetween. A seal ring is inserted into the annular cavity. The above-mentioned seal ring has a first section of smaller wall thickness to leave a space, when inserted into the cavity, forwardly opening and a second section of larger wall thickness extending rearwardly of said first section to resiliently press fit the annular enclosure, the end wall and the outer periphery. The female connector housing has a sleeve formed forwardly of an outer periphery thereof and adapted to be inserted into said space. Due to the existence of the second section of larger wall thickness in the seal ring, the turning over thereof which takes place at the time of engaging and disengaging the prior art waterproof connector is prevented.
