Provided are a conductive film and a preparation method for the same, which relate to the technical field of conductive films. The preparation method for the conductive film includes: forming a metal process layer on a surface of an insulating layer by means of evaporation deposition, wet electroplating or chemical plating; forming a metal transition layer on a surface of the metal process layer facing away from the insulating layer by means of magnetron sputtering; and forming a metal functional layer on a surface of the metal transition layer facing away from the metal process layer. The conductive film obtained by this preparation method can have relatively good conductivity and density while having a relatively thick metal conductive layer.

A metal foil flaring apparatus includes a frame, a flaring mechanism mounted on the frame and having a flaring mouth adapted to open and close, and a first driver mounted on the frame and adapted to drive the flaring mouth to open and close. The flaring mouth has a cone shape gradually contracted toward a front end of the flaring mouth. The front end of the flaring mouth is adapted to be forwardly inserted in a first direction between an inner insulation layer of a cable and a metal foil wrapped around the inner insulation layer when the flaring mouth is closed, flaring the metal foil outwardly into the cone shape.

A wire harness includes a group of electric wires, an electric wire protection tube covering the plurality of electric wires, and connectors provided at both end sides of the group of electric wires, respectively, and each having a dimension larger than an inner dimension of the electric wire protection tube. The electric wire protection tube is constituted of shape-memory polymer and is mounted on the electric wires while it is expanded to have the inner dimension larger than the outer dimensions of the connectors. After the electric wire protection tube is mounted on the electric wires, the electric wire protection tube is heated to a temperature equal to or higher than a glass-transition point such that it is restored to a shape-memory shape.

A cable includes a wire and an electromagnetic shielding layer. The electromagnetic shielding layer covers the wire. The electromagnetic shielding layer is in the form of fiber mesh, including a conductive polymer. A manufacturing method includes: feeding the conductive polymer, melting the conductive polymer, extruding the molten conductive polymer to form a plurality of conductive polymer fibers, covering the wire with the plurality of conductive polymer fibers, and curing the plurality of the conductive polymer fibers to form the electromagnetic shielding layer covering the wire. The electromagnetic shielding layer of the cable of the present application replaces current aluminum foil shielding and metal shielding for conventional wires, decreasing interference by electromagnetic waves produced by electromagnetic induction on electronic devices nearby.

A rodent repellent fiber optic cable includes an outer jacket, one or more optical fibers, and a repellent electrostatically bonded to at least one component of the cable. The one or more optical fibers extend longitudinally through an interior of the cable. The repellent is preferably an olfactory stimulant, such as menthol, configured to repel rodents. In various embodiments, the cable also includes one or more separators and/or a sheath. In embodiments that employ separators, at least one optical fiber is wrapped in, or otherwise surrounded by a separator. In embodiments that employ a sheath, the sheath surrounds an assembly of the cable's internal components.

A rodent repellent cable includes a jacket, a transmission means for facilitating transmission of electrical current or data, and a repellent bonded to at least one component of the cable. A method of manufacturing the rodent repellent cable includes electrostatically bonding a repellent to one or more components of the cable and adding the jacket around the internal components of the cable. The repellent is preferably an olfactory stimulant configured to repel rodents. Prior to adding the jacket around the internal components, the method may also include wrapping, enclosing, or otherwise surrounding one or more of the transmission means with a separator and/or wrapping, enclosing, or otherwise surrounding an assembly of internal components with a sheath. Additionally, prior to adding the jacket around the internal components, an assembly of internal components may be passed through a cooling apparatus to cool the assembly to a pre-determined temperature.

A rodent repellent cable has an outer protective jacket for housing the cable's internal components. The internal components include at least a means for facilitating transmission of electrical current or data, and a repellent bonded to at least one component of the cable. The means for facilitating transmission of electrical current or data include, but are not limited to, wires and optical fibers. The cable may include additional internal components, such as one or more separators and a sheath. The repellent is configured to repel rodents, based on a negative olfactory stimulus when the rodents are subjected to the repellent. This will deter rodents from chewing on wire or cable containing the repellent, which will significantly reduce the incidence of fires of undetermined origin and rodent-inflicted damage to wiring systems universally.
