Patent ID: 7140912

Claim:
A center conductor and insulator assembly comprising: an insulator having a body including a central axis, a shaft portion, a front portion, and an axial channel extending through the front portion and through the shaft portion; the insulator defining a generally cylindrical outer shape at the front portion, with the front portion having a greater outer dimension than the shaft portion; the axial channel centrally positioned about the central axis and adapted to receive a center conductor; the front portion defining a front shoulder and a rear shoulder, each of the front and rear shoulders defining a surface transverse to the central axis; the shaft portion including a rear portion opposite the front portion, the axial channel within the rear portion including a taper which decreases in diameter from an outer end to an inner end, the taper axially aligned with the central axis; and the inner end of the taper defining a smaller diameter than the axial channel and and a circular ledge extending partially into the axial channel proximate the inner end of the taper; a center conductor positioned within the axial channel of the body of the insulator, the center conductor including a front end and a rear end, the rear end positioned within the axial channel adjacent the smaller inner end of the taper, and the front end extending from the axial channel beyond the front shoulder of the front portion, the rear end defining a socket positioned adjacent to the circular ledge.
