Patent ID: 8210867

Claim:
A connection structure of a coaxial harness comprising: a coaxial harness comprising a plurality of coaxial cables lined up, the coaxial cable comprising a center conductor, an inner insulator placed at an outside of the center conductor, an outer conductor placed at an outside of the inner insulator, and a jacket placed at an outside of the outer conductor, a ground bar sandwiching a plurality of the outer conductor exposed at an end terminal part of the coaxial harness; and a substrate being provided with a ground bar connection terminal and a center conductor connection terminal group, the ground bar connection terminal being connected with the ground bar, and the center conductor connection terminal group comprising an alignment of a center conductor connection terminal connected respectively to the center conductor, wherein a plurality of the coaxial harnesses are stacked; a plurality of the center conductor connection terminal groups are provided to the substrate in a direction moving away from the ground bar connection terminal, the plurality of the center conductor connection terminal groups forming a plurality of layers; the ground bar being electrically connected to the one ground bar connection terminal, the ground bar being provided at an end terminal part of the plurality of coaxial harnesses; the center conductor of the coaxial harness, provided at a first layer close to the substrate, is connected to a first group of the center conductor connection terminal group, formed at a region closest to the ground bar connection terminal, and, the center conductor of the coaxial harness, stacked on the coaxial harness provided at the first layer, is connected to the center conductor connection terminal group, provided at a next layer side with respect to the first group of the center conductor connection terminal group; lengths of the center conductor and the inner insulator which are exposed at the end terminal part of a second coaxial harness are longer than those of a first coaxial harness, the second coaxial harness being stacked on the first coaxial harness; and by bending the center conductor and the inner insulator which are exposed at the end terminal part, the center conductor connects the center conductor connection terminal groups.
