Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
A high frequency coupling device comprising inner and outer spring biased conductors, a rotationally extending stationary shoulder, an electrically conductive material interposed between said outer conductor and said shoulder and having a constant diameter aperture therethrough, said outer conductor having an axially extending portion projecting within said aperture and a radially extending end contact portion, and a plurality of at least three slots in said material disposed within parallel planes equally spaced along the longitudinal axis of said material and rotationally oriented in equally spaced increments about said longitudinal axis.
Claim 2
Dependent Claim
90 words
A high frequency coupling device comprising inner and outer spring biased conductors, a rotationally extending stationary shoulder, an electrically conductive material interposed between said outer conductor and said shoulder and having a constant diameter aperture therethrough, said outer conductor having an axially extending portion projecting within said aperture and a radially extending end contact portion, and a plurality of at least three slots in said material disposed within parallel planes equally spaced along the longitudinal axis of said material and rotationally oriented in equally spaced increments about said longitudinal axis.
Claim 3
Dependent Claim
23 words
A high frequency coupling device as defined in claim 1, wherein the slots in said electrically conductive material extend beyond the center thereof.
Claim 4
Dependent Claim
58 words
A high frequency coupling device as defined in claim 2, wherein said electrically conductive material is substantially tubular and has at least one planar end surface, including a conducting element with a radial portion between said shoulder and said planar end surface and an elongated axially extending portion within said aperture and in contact with said outer conductor.
