Abstract
A connector assembly enables a dense grouping of contacts to be joined in one step to a printed circuit board (PCB) while assuring that impedances are matched among all components. A receptacle intended for mounting on the PCB matingly receives a plug which carries terminal contacts of multiple coaxial cable leads. The plug includes a honeycomb grounding block to engageably receive the outer conductor of each coaxial terminal, an inner conductive sleeve being electrically coupled to a signal lead by a first contact. Signal pin contacts within the receptacle and electrically coupled with the PCB are electrically coupled with each inner conductive sleeve when the plug is inserted into the receptacle. Likewise, ground pin contacts within the receptacle and electrically coupled with the PCB have second and third spaced resilient contacts, respectively, engaging the grounding block at distances farther from the nearer to the PCB than the first contacts. As the plug moves toward engagement with the receptacle, the ground pin contacts first move into engagement with the grounding block to initially discharge static electricity. Thereupon, the signal pin contacts engage associated inner sl…
