An armor for a heat shrink kit for joining a first length of heating cable and a second length of heating cable. The armor includes a spring configured to be positioned over at least a portion of the heat shrink kit, a first fastener configured to couple the spring to at least one of the first length of heating cable and the heat shrink kit, and a second fastener configured to couple the spring to at least one of the second length of heating cable and the heat shrink kit. The armor is configured to provide impact protection to the heat shrink kit.

An apparatus that melts and monitors sleeves for installation onto shielded cables. The apparatus includes a heat source for melting the sleeve, cable supports for supporting the cable during the melting process, a sensor system that is configured to measure a dimension of the sleeve during melting, and a computer that is connected to receive sensor data from the sensor system and send heater control signals to the heat source. The computer is configured to receive dimensional data from the sensor system, monitor that dimensional data by performing a dimensional analysis, and then deactivate or remove the heat source in response to dimensional analysis results indicating that the sleeve is fully melted (in the case of a solder sleeve) or only fully shrunken (in the case of a dead end sleeve) onto the cable.

A shield trim is performed by tearing bunched shield strands circumferentially along a circular edge. The apparatus includes a pair of aligned metal plates that have been drilled through multiple times such that holes of varying diameters pass may be passed through both plates. A cable gripper on the entry side of the device clamps the cable in place. A shield gripper on the rear side of the device closes over the exposed shielding of the cable, and the two plates are pushed together. The shield gripper travels with the rear plate, pushing the shield over the wires and causing the shield to bunch between the two plates. With the two plates pushed together, both grippers open and the cable is pulled free from the device. This pull forces a stress concentration on the shield strands as they are pulled and subsequently torn across the sharp edge of the hole, producing a uniformly trimmed shield.

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 cable connection structure is provided with a cable having a plurality of electric wires including core wires made of metal conductors coated with insulators, respectively, and a sheath covering the plurality of electric wires, and an electronic component including a plurality of electrodes. In the cable, the core wires and the insulators of the plurality of electric wires and the sheath are collectively cut perpendicularly to a longitudinal direction at an end of the cable, and tip portions of the core wires including cutting edges of the core wires of the plurality of electric wires are soldered to the plurality of electrodes, respectively.

A method for contacting a wire (1), in particular an aluminum wire, with a connecting body (4), in particular with a plug of a coil body (5), comprising the following steps: connecting the wire (1) materially to the connecting body (4) at at least one point (2, 3); after connecting, enclosing a connecting region including the at least at one point (2, 3) by a shrink tube (6) with an inner glue (7), the shrink tube (6) encompassing the connecting body (4).

The invention relates to a method for sealing a contact point region comprising at least one contact point at an electrical line connection, wherein the line connection comprises at least one electrical line and at least one conductive element electrically connected thereto. The method starts by arranging a shrink tube on the outer circumference of the contact point region, in a first region extending over the contact point region on both sides in the longitudinal direction. This is followed by heating the shrink tube to shrinking temperature. During the heating of the shrink tube, an inductive heating of the electrical conductor is additionally performed, at least in the contact point region, and so hotmelt adhesive arranged inside the shrink tube and/or on the outer circumference of the contact point region is heated to its melting temperature. The invention also relates to a device for sealing a contact point region and to a sealing at such a region.

There is provided a connecting structure for electric cables. A first electric cable includes a first core and a first cover covering the first core. A portion of the first core is exposed from an end of the first cover. A second electric cable includes a second core made of a different metal from that of the first core and a second cover covering the second core. A portion of the second core is exposed from an end of the second cover. A tube is shrunk in a state where the tube accommodates thereinside the portion of the first core and the portion of the second core which are connected to each other. An inside of the tube except for the portion of the first core and the portion of the second core is filled with cured hot-melt.

A system and device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal, wherein a shrinkable tubing is placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal. A band of the high viscosity sealant/adhesive is placed within the heat shrink tubing adjacent to the edge of heat shrink tubing. A band of the low viscosity sealant/adhesive is placed within the heat shrink tubing. Upon the application of heat to the device, the shrinkable tubing starts to recover, the high viscosity sealant/adhesive seals the edge of the shrinkable tubing and the low-viscosity sealant/adhesive flows across and through the plurality of electrical wires to create a seal. The high viscosity sealant/adhesive prevents flow of the low-viscosity sealant/adhesive from contaminating the electrical terminal.
