Abstract
In a coaxial connector, when an inner conductor terminal connected to a signal conductor of a coaxial cable is inserted in and fixed to a dielectric member, which has been received in an outer conductor terminal in advance, by utilizing an upwardly-open space (opening portion) in the outer conductor terminal. A press-clamping portion serving as a connecting portion of the inner conductor terminal connected to the signal conductor is exposed in the opening portion. A matching convex wall is formed on an inner bottom surface of the opening portion to reduce the inner diameter of the opening portion toward the press-clamping portion, thereby matching the characteristic impedance of the connector also in the vicinity of the press-clamping portion. A shielding member closes the opening portion.
Claims13
A coaxial connector for a coaxial cable having a signal conductor, a shielding conductor, an insulator disposed between the signal conductor and the shielding conductor, and a sheath covering an outer periphery thereof, the coaxial connector comprising:
- an inner conductor terminal connected to the signal conductor;
- a dielectric member;
- an outer conductor terminal of a cylinder shape, for receiving the inner conductor terminal through the dielectric member, the outer conductor terminal connected to the shielding conductor;
- and
- a shielding member;
- wherein the outer conductor terminal includes:
- a first opening;
- a side wall;
- and
- a convex wall formed at a position opposed to a connection portion between the exposed signal conductor and the inner conductor terminal, to project toward inside thereof;
- and
- wherein the shielding member is attached to the outer conductor terminal to close the first opening.
A coaxial connector for a coaxial cable having a signal conductor, a shielding conductor, an insulator disposed between the signal conductor and the shielding conductor, and a sheath covering an outer periphery thereof, the coaxial connector comprising:
- a first connector including
- an inner conductor terminal of a female terminal shape, for connected to the signal conductor;
- an dielectric member;
- an outer conductor terminal of a cylinder shape, for receiving the inner conductor terminal through the dielectric member, the outer conductor terminal connected to the shielding conductor;
- and
- a shielding member;
- and
- a second connector including:
