Ground Spring with Strain Relief

A female portion of a BMA connector comprising:

• a generally cylindrical receiver portion for receiving a male portion of a matched BMA connector;
• and
• a ground spring for receiving a ground end of the male portion of the matched BMA connector, the ground spring including:
• a generally annular base portion, and
• a plurality of elongated spring fingers extending from the base portion generally radially inwardly and having inner end faces that together define a substantially circular opening in a center of the ground spring, each of the fingers having a tapered shape including a wider base end and a narrower inner end, and each of the fingers having a longitudinal axis that is aslant relative to a reference line extending from a center of the ground spring to a center of the base end of each finger.

A test and measurement instrument comprising:

• a processor structured to accept an input signal and generate an output therefrom;
• a display unit structured to display the output from the processor;
• and
• an input unit including a female portion of a BMA connector, the female portion of the BMA connector having:
• a generally cylindrical receiver portion for receiving a male portion of a matched BMA connector,
• a ground spring for receiving a ground end of the male portion of the matched BMA connector, the ground spring including:
• a generally annular base portion, and
• a plurality of elongated spring fingers extending from the base portion generally radially inwardly and having inner end faces that together define a substantially circular opening in a center of the ground spring, each of the fingers having a tapered shape including a wider base end and a narrower inner end, and each of the fingers having a longitudinal axis that is aslant relative to a reference line extending from a center of the ground spring to a center of the base end of each finger.
