Abstract
Abstract A connector is disclosed for coupling a coaxial cable to terminal pins on a printed circuit board to provide EMI/RFI shielding for a signal pin on the board. The insulator of the connector has a center contact cavity for receiving a socket contact which is connected to the center conductor of the coaxial cable. Longitudinal grooves in the outer surface of the insulator form outer contact cavities for ground terminal pins on the PC board. Integral resilient contact fingers formed on the shell extend inwardly into the outer cavities to engage the ground pins.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
An electrical connector for connecting a coaxial cable to a plurality of terminal pins including a signal pin and a plurality of ground pins spaced outwardly from said signal pin in a predetermined pattern, said coaxial cable including inner and outer conductors, comprising: a hollow metal shell containing an insulator having a front and a rear, said shell being adapted to be connected to said outer conductor of said cable; a plurality of longitudinally extending grooves in the surface of said insulator opening at said front and arranged in a pattern corresponding to said predetermined pattern whereby said grooves may receive said ground pins; the wall of said shell having contact elements thereon facing one of said grooves for engaging a ground pin; a contact cavity in the interior of said insulator extending from said front to said rear and positioned to receive said signal pin; and a contact mounted in said cavity adapted to be connected to said inner conductor of said cable.
Claim 2
Dependent Claim
164 words
An electrical connector for connecting a coaxial cable to a plurality of terminal pins including a signal pin and a plurality of ground pins spaced outwardly from said signal pin in a predetermined pattern, said coaxial cable including inner and outer conductors, comprising: a hollow metal shell containing an insulator having a front and a rear, said shell being adapted to be connected to said outer conductor of said cable; a plurality of longitudinally extending grooves in the surface of said insulator opening at said front and arranged in a pattern corresponding to said predetermined pattern whereby said grooves may receive said ground pins; the wall of said shell having contact elements thereon facing one of said grooves for engaging a ground pin; a contact cavity in the interior of said insulator extending from said front to said rear and positioned to receive said signal pin; and a contact mounted in said cavity adapted to be connected to said inner conductor of said cable.
