Abstract
Abstract A capacitive cable adapter for providing ground of the same potential at high frequencies for interconnected electrical devices. The capacitive cable adapter, for being interposed between at least two electrical devices interconnected via a shielded cable, comprises two shielded electrical connectors aligned back-to-back with an internal pin-to-pin connection, with the outer shield of each of the two connectors being interrupted approximately at mid distance between the end of the two connectors, thereby forming a gap between the outer protective shield of the two connectors, including a predefined number of capacitive components arranged such that, one of the two pins of each capacitor is connected to the protective shield of one of the two connectors, and the other pin of each capacitor is connected to the shield of the other connector, thereby connecting over the gap the outer shields of the two connectors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
A capacitive cable adapter for being interposed between at least two electrical devices interconnected via a shielded cable comprises: two shielded electrical connectors aligned back-to-back with an internal pin-to-pin connection, each of which electrical connectors has an outer shield with the outer shield of each of the two connectors being interrupted approximately at mid distance between the ends of the two connectors, thereby forming a gap between the shields of the two connectors; and a predefined number of capacitive components arranged around the two connectors such that, one of the two pins of each capacitor is connected to the shield of one of the two connectors, and the other pin of said each capacitor is connected to the shield of the other connector, thereby connecting over the gap the outer shields of the two connectors.
Claim 2
Dependent Claim
