Coaxial cable terminator

摘要

A miniature terminator for a miniature coaxial cable includes a center signal contact extending along an axial extent of the terminator, a second tubular sleeve contact coaxially positioned with respect to the signal contact and having an external contact surface for electrically connecting with an external member for grounding or shielding, a spacer for maintaining electrical isolation and spaced relation of the contacts, and a strain relief for mechanically securing the terminator to the coaxial cable. The terminator impedance substantially matches the impedance of the coaxial cable itself and this characteristic plus miniaturization help make the terminator appear physically and operationally as an extension of the coaxial cable. The invention also relates to a terminator system for coupling a plurality of coaxial cables terminated with respective terminators to further circuitry. The terminator system includes an electrically conductive plate-like member having plural openings therethrough for receiving and electrically engaging with the external contact surface of the second contact of each terminator thereby to couple the same to a common reference potential, such as ground reference potential.
