Abstract
A terminal structure include an internal conductor connection portion, a removal portion and an external conductor connection portion. The internal conductor connection portion is connected to a internal conductor via a conducting portion and an external conductor. The removal portion is provided at a rear side relative to the internal conductor connection portion. The external conductor connection portion is provided at a rear side relative to the removal portion, is formed in the outer peripheral surface of the external conductor, is shut off from the internal conductor connection portion by the removal portion, and is connected to the external conductor.
Claims10
A terminal structure of a coaxial cable, the coaxial cable comprising,
- an internal conductor,
- an internal insulating layer covering an outer peripheral surface of the internal conductor,
- an external conductor covering an outer peripheral surface of the internal insulating layer, and
- an external insulating layer covering an outer peripheral surface of the external conductor,
- the terminal structure comprising:
- an internal conductor connection portion having a conducting portion which is provided on an end face of the coaxial cable and which conducts the internal conductor and the external conductor to each other, the internal conductor connection portion being formed in the outer peripheral surface of the external conductor exposed from the external insulating layer on the side of the end face, the internal conductor connection portion being connected to the internal conductor via the conducting portion and the external conductor;
- a removal portion provided at the rear side relative to the internal conductor connection portion, the removal portion being formed by circumferentially removing a part of the external conductor exposed from the external insulating layer;
- and
- an external conductor connection portion provided at the rear side relative to the removal portion, the external conductor connection portion being formed in the outer peripheral surface of the external conductor exposed from the external insulating layer, being shut off from the internal conductor connection portion by the removal portion, and being connected to the external conductor;
