Abstract

An inner terminal is provided with a crimp barrel portion with which a terminal of a core wire is connected and an electric connecting portion to be electrically connected with a mating terminal. The inner terminal is received in an insulation inner housing. The inner housing is set into a terminal body portion. An outer terminal is provided with a shield member connecting portion with which a shield member is connected and a cylindrical portion in which the electric connecting portion of the inner terminal is positioned, the cylindrical portion mated with a mating connector. An impedance adjusting portion is provided between the electric connecting portion and the crimp barrel portion of the inner terminal.

Claims

1. A shield connector to be connected to an end of a shield electric cable having a core wire covered with a shield member via insulation, the shield connector comprising:

an inner terminal including a crimp barrel portion with which an end of the core wire is connected and an electric connecting portion to be electrically connected with a mating terminal;

an insulation inner housing to receive therein the inner terminal;

an outer terminal including a terminal body portion into which the inner housing is set with the inner terminal received in the inner housing, a shield member connecting portion with which the shield member is connected, and a cylindrical portion in which the electric connecting portion of the inner terminal is positioned, the cylindrical portion mated with a mating connector; and

an impedance adjusting portion is provided between the electric connecting portion and the crimp barrel portion of the inner terminal.

2. The shield connector according to claim 1, wherein

the inner housing is formed with a receiving recess portion to receive the inner terminal, the receiving recess portion is formed with a mating groove portion, and mating the impedance adjusting portion with the mating groove portion enables to position the inner terminal to the inner housing.

3. The shield connector according to claim 1, wherein

the impedance adjusting portion is formed with a bottom plate portion continuous with the electric connecting portion and the crimp barrel portion, and side plate portions rising from respective side portions of the bottom plate portion.

4. The shield connector according to claim 2, wherein

the impedance adjusting portion is formed with a bottom plate portion continuous with the electric connecting portion and the crimp barrel portion, and side plate portions rising from respective side portions of the bottom plate portion.
