Provided is an electronic device that is highly resistant to a water-soluble grinding oil and a method for manufacturing the same. An electronic device includes a main body and a cable including a lead wire, an insulating portion, and an outer coat, a first sealing portion that covers the insulating portion, and a second sealing portion that seals the first sealing portion, the insulating portion is made of a material that is more resistant to a water-soluble grinding oil than the outer coat is, and the first sealing portion is made of a material that has higher adherence to the insulating portion than that of the second sealing portion does.

A shielded electrical cable includes a plurality of conductor sets. Each conductor set includes two insulated conductors. One of the conductor sets also includes a drain wire that generally lies in the plane of the two insulated conductors of the one conductor set. The conductor of each insulated conductor has a size that is not greater than 24 AWG. Each conductor set is substantially surrounded by a shield. The cable also includes first and second non-conductive polymeric layers disposed on opposite sides of the cable. The polymeric layers include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions, in combination, substantially surround the plurality of the conductor sets, and the pinched portions, in combination, form pinched portions of the cable on each side of the plurality of the conductor sets. When the cable is laid flat, the distance between the center of the drain wire of the one conductor set and the center of the nearest insulated conductor of the closest conductor set is 1, the center-to-center spacing of the insulated conductors of the closest conductor set is 2, and 1/2 is greater than 0.7.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about 20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.

A production method for a headline sonar cable (20, 120) that exhibits a high breaking-strength and lighter weight than a conventional steel headline sonar cable. Producing the headline sonar cable (20, 120) is characterized by the steps of: a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34, 134) is slack when surrounded by the jacket layer (52). The structure (34, 134) of the cable (20, 120) retains conductivity upon stretching of the jacket layer (52) surrounding the structure (34, 134) that lengthens the cable (20, 120). For one embodiment of the method a conductor (20) wrapped around a rod (24) and enclosed within a sheath layer (32) forms the structure (34, 134). For another embodiment of the method a braided conductor (122) enclosed within a braided sheath (124) and a polymeric layer (132) forms the structure (34, 134).

It is found and confirmed that a harmonic wave source is a traditionally-used multi-core wire with mutually-exposed core wires. By using a multi-core wire or a single-core wire with mutually-insulated core wires to replace the traditionally-used multi-core wire, a large number of harmonic waves produced by the mutually-exposed core wires can be avoided, the working quality of a power utilization device and an electric energy and electrical signal transmission network is improved at low costs, and electric energy is saved. A method for using a lead wire structure with insulated core wires is used to avoid harmonic ripple noise produced in seamed transmission, or to avoid electric energy waste caused by harmonic ripple noise produced in seamed transmission, or to avoid the influence of harmonic ripple noise produced in seamed transmission on the working quality of a power utilization device or an electric energy and/or electrical signal transmission network. A power utilization device other than an earphone and an electric energy and electrical signal transmission network system, comprising a multi-core transmission lead wire, wherein one or some or all of core wires of the multi-core transmission lead wire are mutually insulated.
