Electrical contact spring probe with RF shielding
First Claim
Patent Images
1. An RF shielded electrical contact probe comprising:
- a) a probe having a barrel with a spring biased plunger extending from a barrel contact end and a barrel lead end open to receive a conductor of a coaxial cable; and
b) a unitary RF shield surrounding said probe through which said plunger reciprocally extends for contact with a test site, the shield being resilient and biased to an extended position so that a terminus of said RF shield surrounds said test site as said plunger contacts same in order to prevent leakage of RF energy to/from neighboring sites.

Abstract
An electrical contact spring probe for testing circuit continuity attaches to the end of a shielded cable for RF (radio frequency) transmission. The probe has a collapsible shield surrounding a contact plunger to prevent leakage of RF energy to or from neighboring circuit points.

5. An assembly for contacting circuit sites receiving or emitting RF energy comprising:
-
a) a coaxial cable having a conductor surrounded by an insulator;
b) a probe having a barrel with a spring biased plunger extending from a contact end and a lead end open to receive the conductor of said coaxial cable; and
c) a single piece RF shield surrounding said probe and terminating in an insulator terminus through which said plunger reciprocally extends for contact with a site, the shield being a resilient metal bellows biased to an outward position so that said insulator terminus surrounds said site as said plunger contacts same in order to prevent leakage of RF energy to/from neighboring sites.
