  • Patent number: 4946394
    Abstract: A connection mechanism for connecting and disconnecting a cable connector to a bushing mounted on an electrical apparatus which is easier to use than cable connectors which require the threading of one electrical contact into another and which require more than one person to operate the connection mechanism. The connection mechanism assists in properly aligning the cable connector and the bushing and securely connects the cable connector to the bushing. Further, this connection mechanism eliminates the problem present in prior connection mechanisms of having to supply significant force in order to break the rubber-to-rubber interface bond which can occur when the connector has been connected to the bushing for a substantial period of time.

  • Patent number: 4944689
    Abstract: A molded connector box for connecting electric power delivery wires to a panel (radiant heating) is formed with side walls and a bottom wall. A power wire inlet slot is formed through one side wall and an outlet slot through another side wall. Each slot has a power wire clamping fixture associated therewith. Blade type wire connectors are positioned adjacent to the inlet and outlet openings and a cooperating wire securing element is connected to its adjacent side wall via a strap in a position to be folded into the box and lock into its respective wire connector to hold the wires in the connector. A cover plate snaps into position to close the connector box.

  • Patent number: 4941844
    Abstract: An electrical connector for providing an insulation displaced connection between first and second insulated electrical wires includes a base and a cap. The base includes a body having at least one groove and a first electrical wire partially embedded in the body. A terminal pin on the end of the first wire extends into and is partially exposed within that groove. A second insulated wire is positioned in and extends through the groove, and the cap is positioned around part of that second wire adjacent the body. The cap is then matingly slid along the base, with a cam surface on the cap slidingly contacting the second wire to force that wire into an insulation displaced connection with the terminal pin on the first wire. When the cap is fully received on the base, the electrical connection is complete without any hand tools being used.

  • Patent number: 4941846
    Abstract: A quick connect/disconnect coaxial connector is described which can be used with unmodified standard coaxial couplings having externally-facing threads. The connector includes a coaxial line segment that is mounted inside a housing body. The latter has movable fingers with inwardly-facing ridges that interlock with the external thread of a coaxial coupling. The coaxial line segment interfits with the coupling for a microwave connection and is movably mounted with respect to the housing body. A sleeve having a cam surface is mounted over the housing body whereby, in a forward position, the fingers are caused to close on a coupling and interlock with its thread while in a rearward position, the fingers are allowed to release from the coupling. The coaxial line segment is spring biased so as to normally urge the fingers towards their release position and into coaxial abutment with a coupling when the fingers are interlocked with the coupling's external thread by the sleeve.

  • Patent number: 4940420
    Abstract: A sealed electrical connector includes one connector member having an oval-shaped cavity containing electrical contacts. A second connector member has a main body of a similar oval shape and having electrical contacts for mating with the contacts in the other connector member. A circular sealing boot is inserted into the cavity so as to deform to the oval shape, thereby providing lateral forces against the cavity wall which ensures that the sealing boot is retained in the cavity and promotes a tight seal when the main body of the second connector member is inserted into the cavity. The sealing boot is formed with elastomeric material into a circular cylindrical shape and is retained in the cavity even when the connector is disconnected.

  • Patent number: 4940421
    Abstract: Disclosed is an improved multi-pin type of water proof electric connector which is guaranteed free of shortcircuit between adjacent pin-and-contact piece connections even if water should invade to any pin-and-connector piece connection through the very small gap between the conductor and the insulation sheath of the wire by the capillary action. The electric connector comprises a male half having contact pieces and a female half having pin terminals in its cavity, and a seal member placed in the space which is to be formed between the outer surface of the plug housing and the inside surface of the socket housing when the male and female halves are coupled. The plug housing has a plurality of hollow protrusions each containing a contact piece, and the seal member encircles each of the protrusions, thereby sealing each pin-and-contact piece connection independently from adjacent pin-and-contact piece connections when the male and female halves are mated.

  • Patent number: 4940425
    Abstract: The contact member defines a channel having a base from which project side walls bowed in portions of which define wire slots. Inwardly convergent wings surmounting each wire slot have insulation severing edges. When a lead is forced into the channel the edges sever the insulation of the lead so that the crests of the bowed portions engage the core of the lead. The wings are then bent across the channel to hold the lead down therein. The portions merge with dimples in the base so that the side walls and the base are continuous as seen in cross section through the wire slots, so that the rigidity of the contact member and the contact force exerted against the core, are improved.

  • Patent number: 4940426
    Abstract: A high density electrical connector assembly, and method of manufacturing same. More particularly, the invention covers an essentially flat, woven screen formed of a plurality of substantially parallel, electrically conductive wires forming the warp wires thereof, where such wires may be as small as 2 mils in diameter. Arranged essentially perpendicular thereto are plural, spaced apart, insulative woof filaments. To one major face of said flat, woven screen is applied a hot laminating film to encapsulate said wires, while to such other major face a comparable film is applied. However, for such other face, the encapsulating film is not coextensive with the screen length, but rather is spaced from the ends thereof so as to provide for connector contacts on each such wire. If desirable, the contacts may be plated.The invention also contemplates means for electrically interconnecting the assembly hereof to a high density circuit pattern, such as found on a PC board.

  • Patent number: 4938713
    Abstract: A transition adapter for terminating flat power cable includes at least a stamped and formed member having opposed plate sections between which an end or an edge portion of the cable is receivable to be terminated. The plate sections have opposing cooperating terminating regions comprised of a plurality of alternating wave shapes and relief recesses, with each wave shape aligned with a recess of the opposing terminating region. When the plate sections are urged together under sufficient force, shearing edges along each side of each wave shape shear the cable conductor by cooperating with shearing edges of the adjacent wave shape of the opposing terminating region, scissors-fashion. Crests of the wave shapes deflecting the sheared cable portions into the opposing relief recesses, forming a series of interlocking wave joints across the intermeshing terminating regions and terminating the cable between the plate sections.

  • Patent number: 4932901
    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.
