  • Patent number: 10674622
    Abstract: A seal structure includes a container, a sealant applied in liquid form that cures to a gel, and a cap that applies pressure to the gel. The container surrounds at least one opening in an assembly for the passage of elongated members such as wires. The container defines a chamber that is in communication with the opening and surrounds the wires passing through the opening. A closure spans the opening and is in contact with an inner end of the container. The chamber and the at least opening are partially filled with a predetermined quantity of sealant in liquid form, which cures into a viscous gel. The cap is configured to engage with the container and includes a platform that is positioned within the container and in contact with the gel sealant. In this arrangement, the cap applies positive pressure to the gel sealant.

Each splice member incudes two channels. Respective two channels of each splice member are aligned with each other in the closed mode to form a first cavity and a second cavity. The walls of the first cavity bear against a first length of wire, and the walls of the second cavity bear against a second length of wire which is mechanically and electrically coupled to the first length of wire within the first cavity.

  • Patent number: 5519171
    Abstract: The wire splice enclosure of the preferred embodiment provides a two-piece sealable cylindrical enclosure having a tension plate at each end formed parallel to the axis of the enclosure. Each tension plate is formed with a serpentine concave track of a size adapted to snugly receive a wire for splicing, with a hole adjacent the track inner end sized to allow the wire to snugly pass through into a chamber area. A pair of hooks within the chamber area provides support for the wire ends after splicing. The two pieces of the chamber are adapted to seal together with a quarter turn locking motion.

  • Patent number: 5461200
    Abstract: Long flexible members such as hoses, electric cords and cables tend to be springy and elastic. They are not easily coiled and stored. They tend to straighten out when bent into a desired shape. They tend to tangle and interfere with operations. The invention incorporates an elongate wire element running parallel to the long axis of the flexible member. The wire element is encased in the covering of the flexible member. The wire element is a conformable shape-retaining material such as a compliant soft iron or steel. It renders the entire member shape-retaining so that it may be conveniently coiled for storage or positioned for use. An embodiment for retrofitting an existing flexible member provides the wire element encased in a covering which wraps around a flexible member and then seals closed to form a shape retaining sleeve about the member.

  • Patent number: 5446241
    Abstract: A two member connector to twist connect two ductile wires, releasable coupling means is provided to couple inner ends of the members together, each member has a cavity means including a pair of transversely spaced wire chambers each sized to accept a wire to be joined, the cavity means of at least one member includes a central chamber disposed between the wire chambers of that member and sized to accept two wires when twist connected, a slot connects the central chamber with each of its associated wire chambers and the sides of the slots provide brake surface means; to form a twist connection the two wires are housed in the wire chambers of both members and the members are contra-rotated to bring torque applying and reaction shoulders of each cavity means into contact with the wires to force the wires together and twist connect them, in the formation of the twist connection the wires in the member with the central chamber are drawn into the central chamber from the wire chambers over the brake surface means w

  • Patent number: 5392017
    Abstract: The choke coil comprises a bead of a soft-magnetic material in which a number of ducts extend in parallel. An electrically conductive wire comprising fee ends is accommodated in the ducts. The choke coil comprises means for shielding a portion of the turn which extends outside the ducts. To this end, for example an electrically insulating housing is arranged around the bead. The housing consists of two approximately cylindrical portions, each of which comprises a substantially closed end face which is situated on a first end portion. The cylindrical portions are axially slid over the bead with their second open end portion fitting one into the other. In each end face there is provided at least one opening for feeding out the wire. When the choke coil is also provided with electrically insulating caps having a wire passage in the prolongation of the axis of the bead, the wire fed out will be oriented along said axis.

  • Patent number: 5162617
    Abstract: A waterproof wire-sockets electrical junction cover suitable for use in wet environments includes a chamber to house the wire-sockets electrical junction. Sealable passages on one end of the chamber allow electrical wires to pass into the chamber. On the other chamber-end, a sealable port allows the wire-sockets itself to enter the chamber. The electrical wires are mechanically and electrically joined using the wire-sockets. The resulting junction is then drawn through the aforementioned sealable port into the chamber. The port is closed, thereby completely watertight sealing the wire-sockets electrical junction.
