A molded portion-equipped electric cable that includes an insulated conductor and does not require an insulating cover removing step is provided. The molded portion-equipped electric cable includes: a linear conductor portion; a terminal that is connected to an end portion of the conductor portion; a molded portion that covers a connecting portion between the conductor portion and the terminal such that the terminal protrudes from one end side of the molded portion and the conductor portion protrudes from the other end side of the molded portion; and an insulating cover portion that covers over the molded portion and the conductor portion and is formed by shrinking a heat shrinkable tube.

A method of heat shrinking a protective sleeve onto an electrical connection includes an initial step of providing an electrical connection, such as between an electrical wire and an electrical termination device, and a protective sleeve having an inner surface and an outer surface. The inner surface of the protective sleeve has an adhesive material applied thereto and is disposed about the electrical connection. Thermal energy is applied to the outer surface of the protective sleeve so as to increase the temperature thereof. Either before, at the same time, or after this step, the temperature of some or all of the electrical connection disposed within the protective sleeve is increased, such as by induction heating. As a result, the protective sleeve shrinks onto the electrical connection, and the adhesive material forms a tight bond between the protective sleeve and the electrical connection.

A process of heat recovering tubing includes forming a multilayer tubing assembly, heating the multilayer tubing assembly to a shrink temperature to form a heat-recovered tubing assembly, and visually inspecting the heat-recovered tubing assembly for a presence of at least one colorant. A multilayer tubing assembly and an adhesive assembly are also disclosed. The multilayer tubing assembly includes an outer tubing of a heat-recoverable material, an inner tubing of a heat-meltable material, a substrate encased by the inner tubing, at least one protrusion encased by the inner tubing, and an adhesive strip including an adhesive composition and the colorant. The outer tubing encases the inner tubing. The adhesive strip is located between the substrate and the protrusion.

A structure for connecting electric wires in which a single-core conductor made of a single metal rod is connected to a flexible conductor made of a plurality of elemental metal wires and having a higher flexibility than the single-core conductor. A clamping portion formed at one end of the single-core conductor is connected to the flexible conductor with the clamping portion clamping the flexible conductor on two sides thereof in a direction transverse to the direction in which the electric wires extend. This structure can enhance the adhering strength of the connection as the flexible conductor and the single-core conductor do not peel off from each other even if the flexible conductor is deflected.

A wire harness that comprises a connecting portion in which a first conductor exposed at a terminal portion of the first wire by stripping an insulating coating therefrom is connected to a second conductor exposed at a terminal portion of a second wire by stripping an insulating coating therefrom, the second wire having a higher flexibility than the first wire. The wire harness also comprises two layers of shrinkable tubes fitted around the outer circumference of the connecting portion. According to this structure, even if one of the shrinkable tubes is torn, the other shrinkable tube can provide protection to the connecting portion, thus improving the durability of the connecting portion.

A termination connection box for a direct-current (DC) cable, including: a connecting semiconducting layer configured to cover an exposed conductor of the DC cable and an insulating layer of the DC cable; a conductor withdrawal rod electrically connected to the exposed conductor of the DC cable; and a heat shrinkable tube formed of functionally gradient material having non-linear electrical characteristics. The heat shrinkable tube includes: a first end electrically connected to the conductor and which covers a portion of the conductor withdrawal rod and the connecting semiconducting layer; a second end opposite to the first end, electrically connected to the outer semiconducting layer, and which covers a portion of the outer semiconducting layer; and a middle portion positioned between the first end and the second end, and which is in direct contact with and covers an outer circumferential surface of the insulating layer.

A textile sleeve for routing and protecting a plurality of elongate members in spaced relation from one another is provided. The sleeve includes a single piece, monolithic wall of interlaced yarn extending lengthwise between opposite ends of the sleeve. The wall includes a plurality of circumferentially continuous, tubular wall sections extending lengthwise between the opposite ends, with adjacent tubular wall sections being fixed in laterally spaced relation from another by an intervening single layer section. At least some of the yarn within each tubular wall section is provided as heat-shrinkable yarn, thereby providing each tubular wall section as being heat-shrinkable from a first, diametrically enlarged assembly state to a second, diametrically constricted state about a corresponding elongate member contained therein.

A conductive path includes: a first conductor in which a terminal end portion serves as a first connection portion; a second conductor in which a second connection portion at a terminal end portion is coaxially fixed to the first connection portion; a support member that is more rigid than the first and second conductors, and is disposed so as to extend along a fixed portion between the first and second connection portions; and a heat-shrinkable tube (holding member) that integrates the support member with the first and second conductors while enveloping the support member. Even when an external force acts on the first and second conductors so as to skew the axes of the two conductors, the support member and the heat-shrinkable tube keep the two conductors in the coaxial state.

A conductive wire has a peripheral disposition part disposed around a center member and an extension part integrally formed with the peripheral disposition part so as to extend from the peripheral disposition part. A plurality of conductive wires are disposed. A sheath is disposed so as to cover the center member and the peripheral disposition part. A tube is disposed so as to surround an end portion of the sheath and a part of the extension part, and is thermally shrinkable. An adhesive is disposed inside the tube and is melted or softened by heat.

A conductive member to be routed in a vehicle includes a pipe member being tubular in shape and capable of keeping a shape, a core wire connected to an end portion of the pipe member and having flexibility, a connector terminal connected to an end portion of the core wire on a side that is opposite to the pipe member, and a corrugated tube covering the pipe member and the core wire and having flexibility.
