Coaxial electric connector

摘要

Good signal transmission characteristics can be stably obtained by a simple structure. A pressure-contact surface of a cover inner surface of a shell cover part 13b, which is openably/closably coupled to a cylindrical opening of an external conductor shell 13a, and an insulative pressing plate 11d is provided with a void part 14, which separates at least one of them from the other one. By virtue of this, it is configured that the characteristic impedance about the cable-shaped signal transmission medium SC can be adjusted by the void part 14, and the matching degree (VSWR) of the characteristic impedance with respect to transmission signals can be easily and appropriately matched.

1. An electric connector having
an insulating housing to be coupled to a terminal part of a cable-shaped signal transmission medium; an external conductor shell consisting of an approximately hollow cylindrical member attached so as to cover part of an external surface of the insulating housing, an internal conductor contact attached to an inner region of the insulating housing; a shell cover part for opening/closing a cylindrical opening of the external conductor shell which is openably/closably coupled to the cylindrical opening of the external conductor shell; an insulative pressing plate provided so as to be integrally opened/closed with the shell cover part in the insulating housing extending along a cover inner surface of the shell cover part; wherein, a predetermined region of the cover inner surface of the shell cover part is configured to be disposed so as to be opposed to the insulative pressing plate when the shell cover part is closed so as to cover the cylindrical opening of the external conductor shell; the electrical connector comprising, a void part provided in a region in which the cover inner surface of the shell cover part and the insulative pressing plate are opposed to each other, the void part formed by separating at least one of the cover inner surface of the shell cover part and the insulative pressing plate from the other.
