Abstract
Abstract A triaxial contact assembly for use with a ground plane electrical connector includes an outer conductor which is grounded to the ground plane of the connector. The intermediate and inner contacts of the triaxial contact assembly have printed circuit board tails on their ends. The arrangement is such that bonding of the insulators to the contacts is eliminated via a cap which holds all internal contact assembly components in place. The cap, in turn, is held in place by crimping the outer contact.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A triaxial contact assembly for termination to printed circuit boards comprising: an outer contact; an intermediate contact concentrically disposed within the outer contact; an inner contact concentrically disposed within the intermediate contact; an outer dielectric insulator concentrically disposed between the outer and intermediate contacts; an inner dielectric insulator concentrically disposed between the intermediate and inner contacts; the intermediate and inner contacts each carrying printed circuit board tails; a cap concentrically disposed within the outer contact abutting a surface on the inner contact for holding the intermediate and inner contacts and the inner and outer insulators projecting forwardly within the outer contact; and means for holding the cap in place near the rear of the outer contact.
Claim 2
Dependent Claim
116 words
A triaxial contact assembly for termination to printed circuit boards comprising: an outer contact; an intermediate contact concentrically disposed within the outer contact; an inner contact concentrically disposed within the intermediate contact; an outer dielectric insulator concentrically disposed between the outer and intermediate contacts; an inner dielectric insulator concentrically disposed between the intermediate and inner contacts; the intermediate and inner contacts each carrying printed circuit board tails; a cap concentrically disposed within the outer contact abutting a surface on the inner contact for holding the intermediate and inner contacts and the inner and outer insulators projecting forwardly within the outer contact; and means for holding the cap in place near the rear of the outer contact.
Claim 3
Dependent Claim
