A wire insulator apparatus includes an insulator/separator member, a cap portion, a tube and potting material. The insulator/separator member has apertures formed therein for receiving a plurality of wires. By threading the wires through the insulator/separator member, the wires are spaced apart so that a potting material can be molded to provide a complete seal from the environment, particularly conductive liquids such as ammonia, which may cause short-circuiting between the wires. Individual wires are terminated in the cap portion, and the cap portion, the insulator/separator member and the wire ends are positioned within a tube or a mold portion depending on the application, and a potting epoxy is fluidly inserted within the tube. The epoxy surrounds or encases the wire ends within the tube or mold to insulate the wire ends in an airtight seal.

A splice connector, such as a twist-on wire connector, is pre-filled with a plurality of compounds arranged in a corresponding plurality of layers. When the twist-on wire connector is applied to the electrical conductors, the compounds will generally remain in the plurality of layers to thereby allow each of the compounds to perform a different, intended function.

A conducting wire end portion joining method is a method for conductively joining together end portions of conducting wires each covered with an insulation coating. The conducting wire end portion joining method includes: adjoining end portions of two winding wires, and bringing the end portions of the conducting wires of the two winding wires into contact with a conductive coating material stored in an insulating cap having a property of shrinking when heated; and shrinking the insulating cap by heating to fix the shrunken insulating cap around the insulation coatings of the end portions of the two winding wires, and joining together the end portions of the two winding wires by conductively connecting the conducting wires of the two winding wires via the hardened conductive coating material.

The assembly includes a protective elastic tubular body and a tubular core for holding the tubular body expanded including a first part and a second part which are associated, the core being in an operating position in which the second part covers the first part, and being configured for an elongate member to be inserted into its internal space in operating position and for a pull then applied to the first part to make it slide relative to the second part to reach an extended position in which it can no longer move in relation to the second part; the second part including legs projecting axially from a collar and connected to each other exclusively by the collar; in the operating position the collar and legs surround the first part; and in the extended position the collar surrounds the first part and the legs are axially beyond the first part.

A termination connection box for a direct-current (DC) cable, in which when an outer semiconducting layer, an insulating layer, and an inner semiconducting layer are sequentially removed, a conductor is exposed, the termination connection box, the termination connection box including: a connecting semiconducting layer configured to cover the exposed conductor and the insulating layer; a conductor withdrawal rod electrically connected to the conductor; and a heat shrinkable tube configured such that one portion thereof covers an outer circumferential surface of the cable insulating layer and one end and another end thereof are respectively electrically connected to the conductor and the outer semiconducting layer.

A system for servicing cable includes a plurality of jaws operable between an open position for receiving a cable in a direction transverse to a cable axis such that the cable extends axially beyond the jaws in two directions, and a closed position for engaging and rotationally fixing the cable about the cable axis. A tool arrangement is disposed proximate to the base and includes at least one tool operable to perform work on the cable when the cable is engaged by the jaws. The tool arrangement is operable to perform at least one of a rotational movement around or an axial movement along the cable axis and to operate the tool.

A wire harness is provided with a cable including wires coated with a sheath, a rubber stopper that covers an end of the sheath together with a portion in a longitudinal direction of the wires, and a cover made of a harder material than the rubber stopper and accommodating the rubber stopper. The rubber stopper integrally has a sheath sealing portion having an inner peripheral surface that comes into contact with an outer peripheral surface of the sheath, and a wire sealing portion including plural insertion holes to which the wires are inserted. The cover integrally has a sheath holding portion that crimps and holds an uncovered portion of the sheath that is not covered by the rubber stopper, and a rubber stopper holding portion that crimps and holds the rubber stopper.

A termination assembly for a heating cable includes a first assembly that connects to a first conductor of the heating cable and includes a first cam rotatable about a first base frame to contact the first conductor from a first side, and a second cam rotatable about the first base frame to contact the first conductor from a second side. A second assembly connects to a second conductor of the heating cable and includes a third cam rotatable about a second base frame to contact the second conductor from the first side, and a fourth cam rotatable about the second base frame to contact the second conductor from the second side. Each cam includes teeth configured to pierce through a jacket and core material of the heating cable when the respective cam is rotated, and a first end portion adjacent to the teeth to contact the respective conductor.

An apparatus for retrofitting a HID lighting system includes using existing components of previously installed HID lighting systems such as its ballasts while replacing some capacitors to adjust the power supplied to a retrofit LED luminaire. Unused ballast drivers are removed, and a self-contained ballast driver assembly is mounted into the electronic control enclosure of the previously installed lighting system. Some of the retrofit LED luminaires include an uplighting lens, an optic, or a diffuser for providing uplight. An aiming bracket and an aiming plate allow for the horizontal aiming angle of a light luminaire to be set.

A wire terminal protector, an assembly component, and a household cooking appliance are provided. The wire terminal protector includes a first component and a second component. The first component and the second component are assembled to form an enclosed space. One or both of the first component and the second component are provided with a first through-hole that connects the enclosed space to an outside. A wire terminal is accommodated in the enclosed space, and the first through-hole is configured for insertion of a wire into the enclosed space.
