摘要： The present disclosure provides a multilayer tube which is flexible and exhibits excellent durability in terms of airtightness, while including as a main component, a polytetrafluoroethylene. The present disclosure is achieved by a multilayer tube which includes a main component, a polytetrafluoroethylene, wherein if the total porosity (%) of the tube is plotted on the horizontal axis of a coordinate graph and the Martens hardness HM3mN of the tube as described below is plotted on the vertical axis, coordinate points representing characteristics of the multilayer tube are within a quadrangle that is bounded by four coordinate points, namely a (7.5, 0.25), b (8, 0.02), c (25, 0.38) and d (25, 0.03) on the graph. Meanwhile, HM3mN represents the Martens hardness at the time when the test force reaches 3 mN during the process of load application, with the maximum test force being set to 4 mN, if the inner surface of the tube is measured in accordance with ISO 14577.

摘要： The present invention relates to a coaxial cable, and particularly to a small-diameter coaxial cable for use in frequency bands of 100 MHz or more. The present invention addresses the problem of providing a coaxial cable which has excellent flexibility, a small outer diameter, and excellent shielding characteristics. The problem is solved by a coaxial cable having an outer conductor which is formed by mixing and laterally winding strands in the same direction, the strands having an outer diameter difference of not less than 10% between a large-diameter strand having a maximum outer diameter and a small-diameter strand having a minimum outer diameter.

摘要： A connector includes a female-side connector and a male-side connector including an inner engagement portion and an outer engagement member or portion. The outer engagement member or portion has: an outer engagement member or portion body covering the female-side engagement portion from outside when the male-side connector is inserted into the female-side connector; and has a holder that, when the male-side connector is inserted into the female-side connector, covers the screw thread on the female-side engagement portion from outside, and fills a gap between the female-side engagement portion and the outer engagement member or portion body. The holder is disposed on an end portion side of the male-side connector from the inner engagement portion in a longitudinal direction of the male-side connector, and disposed so as to pinch the female-side engagement portion in cooperation with the inner engagement portion when the male-side connector is inserted into the female-side connector.
