A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step is performed after the first waterproofing step is performed.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a terminal to one end of an electric wire, a step of crimping another terminal to the other end of the electric wire, and a waterproofing step of providing a sealing member at the other end of the electric wire so as to fill gaps between conductive element wires of an element wire bundle. The waterproofing step includes, in this order, a step of applying a resin to the element wire bundle to block at least a part of an inner portion of a tubular insulating sheath, a step of waiting during curing of the resin or until the curing is completed, and a step of applying the moisture curable resin to the element wire bundle, blocking a remaining portion of the inner portion of the insulating sheath, and curing the resin.

Provided are devices, methods and systems. A cover system may include a unitary cold shrinkable, tubular, elastomeric cover sleeve defining a cover sleeve through passage that is configured to receive the electrical cable. The cover sleeve may include a first type of stress control element and a second type of stress control element that is different from the first type of stress control element. A holdout maintains the cover sleeve in an expanded state in which the cover sleeve is elastically expanded and when removed, permits the cover sleeve to radially contract to a contracted state about the electrical cable. The first type of stress control element includes a geometric stress cone that includes an electrically conductive and/or semiconductive portion that is configured to conductively engage a semiconductor layer of the electrical cable. The second type of stress control element includes a high-K stress relief element.

A lighter and more space-saving wire harness that has a function of retaining the shape of part of electric wires and an electromagnetic shield function. The wire harness includes a plurality of spliced and sheathed electric wires and a conductive shielding member. Each of the spliced and sheathed electric wires has a spliced core wire and an insulating sheath that covers the spliced core wire. The spliced core wire includes a first core wire that is a single conductive wire, and a second core wire that is a bundle of a plurality of conductive wires that are thinner and shorter than the first core wire, the second core wire being connected to an end portion of the first core wire. The shielding member is formed in a flexible tubular shape, and collectively covers the plurality of spliced and sheathed electric wires.

Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing. Additionally, the smooth outside surface and relatively small diameter of the fiber encapsulated cable are desirable attributes for well intervention work because the smooth surface is more resistant to chemical attack than braided wire while the smooth surface and relatively small diameter provide little viscous drag while fluids are pumped through the coil tubing in the course of intervention operations.

A method for installing an elastomeric cover sleeve on an electrical connection including a connector and a cable having a cable axis includes: providing an installation tool including a slide portion; premounting the installation tool on the cable such that the slide portion extends along the cable axis and covers a portion of the cable; thereafter, sliding the cover sleeve onto the cable and onto the slide portion of the premounted installation tool to a parked position wherein the slide portion is interposed between the cover sleeve and the cable; installing the connector onto the cable; and thereafter, sliding the cover sleeve along the cable axis and the slide portion onto the connector.

The present disclosure relates to a cable sleeving tool for applying a split-sleeve over a cable structure. The cable sleeving tool includes an inner guide member defining an inner passage for receiving a cable structure desired to be sleeved. The inner passage extends along a passage axis between an upstream end of the inner guide member and a downstream end of the inner guide member. The inner guide member also includes an inner surface defining the inner passage and an outer sleeve expansion surface for expanding the split sleeve. The cable sleeving tool also includes an outer guide member that surrounds at least a portion of the inner guide member. The outer guide member includes a sleeve containment surface that opposes the outer sleeve expansion surface. The outer sleeve expansion surface and the sleeve containment surface cooperate to define a sleeve passage having a transverse cross-sectional shape that curves generally about the passage axis.

A device and method for sheathing shrink tubing onto materials such as wire, tape, or cables. The device cannot only sheath short lengths of shrink tubing onto material, but also sheath long lengths shrink tubing onto material. Varying embodiments of this device can insulate whole lengths of material with shrink tubing as well as covering certain sections of material for a more precise application.

A method utilizes a funnel system and robotic end effector grippers to feed an unjacketed portion of a shielded cable through a sleeve. The funnel is designed with one or more thin extensions (hereinafter “prongs”) on which a sleeve is placed prior to a cable entering the funnel. Preferably two or more prongs are employed, although a single prong may be used if properly configured to both guide a cable and fit between the sleeve and cable. The prongs close off the uneven surface internal to a sleeve and provide a smooth surface for the cable to slide along and through the sleeve, preventing any damage to the exposed shielding. The sleeve is picked up and held on the prongs using a robotic end effector. If the sleeve is a solder sleeve, the robotic end effector has grippers designed to make contact with the portions of the solder sleeve that are between the insulating rings and the central solder ring.
