Terminal unit and connector therefor

Abstract

To provide a terminal unit with enhanced impedance matching.SOLUTION: A terminal unit 14 includes one or more internal terminals 20, a dielectric member 30, and an external terminal 40, the internal terminal 20 includes a contact portion 21 that comes into contact with a connection target (mating connector), and a crimping portion 24 that is crimped to the internal conductor 91. The contact portion 21 is provided on one side in the axial direction, and the crimping portion 24 is provided on the other side in the axial direction. The internal terminal 20 further includes an impedance adjustment portion 25 connected to the crimping portion 24. The impedance adjustment portion 25 protrudes toward the other side in the axial direction with respect to the crimping portion 24.SELECTED DRAWING: Figure 7
