Publication number: 20240161945Abstract: A coaxial cable includes an inner conductor, an insulation covering the inner conductor, an outer conductor covering the insulation, and a sheath covering the outer conductor. The inner conductor is a compressed conductor including a central element wire and multiple peripheral element wires surrounding the central element wire. The inner conductor has a compressibility of 23.0% or more and 35.0% or less in percentage. The compressibility is calculated from a sectional area S1 and the sectional area S2 of the compressed conductor by Compressibility=[1?S2/S1]. The sectional area S1 is calculated from the outside diameter D of the central element wire and the total number n of the central and peripheral element wires by S1=n×?×0.25×D2. The outside diameter of the insulation is 1.25 mm or more and less than 1.75 mm.Type: ApplicationFiled: March 15, 2022Publication date: May 16, 2024Inventors: Atsuko SHINOMIYA, Kenichiro IWAMA, Motoi MATSUDA, Yuji OCHI

Patent number: 9704615Abstract: A shielded cable comprising two insulated wire covered with first and second metal clad resin tapes each of which has a laminated metal layer and a resin layer. The first metal clad resin tape covers the circumference of the two insulated wires by open-wrapping and the second metal clad resin tape is spirally wrapped around the circumference of the first metal clad resin tape. The first and second metal clad resin tapes are disposed while the metal layers face each other and, in the portion where the second metal clad resin tape is overlapped by wrapping, the metal layer of the overlapped one second metal clad resin tape and the metal layer of the other second metal clad resin tape are in contact with the first metal clad resin tape. The shielded cable can prevent sharp signal attenuation in a high frequency region and is easy to bend and flexible.Type: GrantFiled: November 25, 2015Date of Patent: July 11, 2017Assignee: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Motoi Matsuda, Katsumi Karube, Yuto Kobayashi, Takaki Endo, Yoshiaki Arakawa, Hayato Matsushita

Publication number: 20110247856Abstract: There is provided a shielded cable wherein a metal coated resin tape is helically wound, whereby a plurality of signal cables are shielded, and no sudden signal attenuation occurs in high frequency ranges. A shielded cable has a shield conductor produced by helically winding a metal coated resin tape together around the circumference of a plurality of signal wires, upper and lower metal foils are in electrical contact with each other in overlap parts of the winding of the metal coated resin tape. The metal coated resin tape is formed with one edge part folded back so that the metal foil is disposed on an outward side. The overlap width of the winding of the metal coated resin tape is one-quarter to one-half of the tape width.Type: ApplicationFiled: March 22, 2011Publication date: October 13, 2011Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Motoi MATSUDA, Katsumi KARUBE, Satoshi OKANO
