Abstract

The invention discloses a coaxial cable and the production method. In every coaxial cable (11), except the end of an outer sheath (12), parts of an outer conductor (13), an insulator (14) and a central conductor (15) are exposed by the manner of cascade. A ground bar (20) is provided with a locked nail (23) for locking the coaxial cable (11) to fasten the ground bar (20) to the exposing part of the outer conductor (13). The coaxial cable (11) is fixed between the ground bar (20) and a pressing component (30).

Description

technical field [0001] The present invention relates to coaxial cables and methods of making the same. For example, the present invention relates to a coaxial cable capable of directly connecting the coaxial cable to, for example, an interconnection circuit provided on a substrate without using a connector, and a method of manufacturing the same. Background technique [0002] An electrical connector for connecting a plurality of coaxial cables to an interconnection circuit on a substrate is currently known (for example, see Patent Document 1: JP-A-2005-302604). [0003] As shown in FIG. 9, an electrical connector 100 for electrically connecting a coaxial cable 101 to a receptacle (not shown) (by inserting the former into the latter) is configured with the following parts: an insulating housing 102, which is composed of, for example, plastic made of resin; a plurality of conductive terminals 103 arranged at predetermined intervals in the width direction of the housing 102; a...
