ABSTRACT:
The probe is a tubular shaped device held in one hand such as one would hold a hypodermic syringe. An extended L shaped hook acquires and presses an electrical wire to be tested into the apex of a V notched holding block. The hook and holding block, with test wire in between, are held pressed together by spring action. The holding block has a guide and outlet hole centered at the apex of the V notch which receives and guides a needle probe along a radial line towards the central axis of the wire. The needle pressure and position are controlled independently by the operator via a threading mechanism. Proper penetrating pressure can be applied for a range of wire sizes and insulation types. The needle is removable for sharpening or replacement.
