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.

A heat-shrinkable protective element having at least one protective layer is obtained from a polymeric composition having a polymer material, where the polymeric composition additionally has an electrically conducting filler having a BET specific surface of at least 100 m.sup.2/g according to Standard ASTM D 6556.

A heating system for heating a heat shrink layer of a heat shrink component during a heat shrink process includes a heating unit arranged in thermal contact with at least a part of the heat shrink layer and heating the heat shrink layer to a heat shrink temperature. The heating unit has a first heating zone and a second heating zone. The first heating zone has a different heating energy than the second heating zone for a period of time of the heat shrink process.

A sealing system for forming an environmentally sealed joint with an elongate member includes a tubular substrate, a pre-expanded cover unit, and a flowable sealant. The tubular substrate includes an integral guide feature and defines a substrate bore to receive a portion of the elongate member. The pre-expanded cover unit includes a holdout and a tubular cover sleeve. The holdout includes a helically wound strip forming a tubular holdout body and a rip cord. The holdout body defines a holdout passage extending axially therethrough. The tubular cover sleeve is mounted on the holdout body. The holdout maintains the cover sleeve in a radially elastically expanded state. With the elongate member positioned with a portion thereof extending from the tubular substrate and a layer of the sealant mounted on an outer surface of the tubular substrate and/or on an outer surface of the elongate member, the pre-expandable unit can be mounted around the layer of sealant and the holdout can then be removed from the cover sleeve by withdrawing the rip cord through the holdout passage between the layer of the sealant and the holdout body to remove the holdout body and thereby permit the cover sleeve to radially contract about the tubular substrate and the elongate member, and the guide feature serves to prevent or inhibit the rip cord from contacting the layer of the sealant as the rip cord is withdrawn through the holdout passage.

A cable water stop structure for a cable that includes plural insulated wires and a sheath covering the plural insulated wires includes a heat shrinkable tube that is shrunk to wrap around an end of the sheath and the plurality of insulated wires extending from the end, and a cover that is attached to sandwich the end of the sheath, the plurality of insulated wires extending from the end and the heat shrinkable tube. The cover includes a gripping portion gripping the heat shrinkable tube to restrict the heat shrinkable tube from moving along a cable longitudinal direction.

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.

The heat-recoverable article according to the present invention has a cylindrical shape and includes a base material layer. The base material layer contains a polyolefin-based resin. In the base material layer after being heated at 180 C. for 2 minutes, a melting-point peak temperature is 115 C. or higher and 128 C. or lower, a heat of fusion of a total resin component is 80 J/g or more and 150 J/g or less, a storage modulus at 120 C. is 4 MPa or more, a gel fraction is 40% by mass or more and 80% by mass or less, and a storage modulus at 180 C. is 0.5 MPa or more and less than 3.0 MPa. The polyolefin-based resin is preferably a mixture of a first polyolefin-based resin having a melting point of 125 C. or higher and 135 C. or lower and a second polyolefin-based resin having a melting point of lower than 125 C.

A system and method for installing a section of heat shrink tubing on a wire is disclosed. The system includes an infeed guide that receives the continuous length of tubing and initially opens the tubing from a compressed condition. The continuous length of tubing is received in a cutting guide and cut to a desired length. After cutting, a pair of spaced support jaws move together to open the cut section of tubing. A funnel having a first opening and a second opening is moved into engagement with the section of tubing such that the second opening is received within the section of tubing. A wire is inserted into the funnel which guides the wire into the cut section of tubing. Once the wire is received within the cut section of tubing, the funnel and support jaws are removed and the wire is removed with the section of support tubing installed thereon.

A high voltage connection between a first line of a traveling wave tube and a second line of a voltage supply unit for the traveling wave tube includes a plug which is connected to an end section of the first line or of the second line by a crimp connection, and a socket which is connected to an end section of the other line by a crimp connection. Furthermore, a method for manufacturing a high voltage connection is also described.

A cable waterproof structure includes a plurality of insulated wires and a sheath covering the plurality of insulated wires collectively, a heat shrinkable tube with adhesive that includes adhesive inside, and is provided and shrunk so as to cover an end of the sheath and a circumference of the plurality of insulated wires extended from the end of the sheath, and a fixing heat shrinkable tube that includes no adhesive inside, and is provided and shrunk so as to cover a part of the heat shrinkable tube with adhesive that covers the sheath and a circumference of the sheath extended from the heat shrinkable tube with adhesive, wherein a shrinkage start temperature of the fixing heat shrinkable tube is higher than a shrinkage start temperature of the heat shrinkable tube with adhesive.
