Abstract: An adjustable probe tip has a female part that includes a ring structure and a hook extending therefrom. The ring structure has a threaded bore. The probe tip also has a male part having a threaded cylindrical surface that is screwably received by the female part. The male part has an inner bore that is not threaded and receives a metal probe tip cap therein. Screwing the male part into the threaded bore of the female part adjusts the relative distance between the hook and the end of the male part. The metal cap is received in the end so that a wire trapped between the metal part and the hook may be pierced by a probe tip of the metal cap. A test probe may be received by the male cap and bore of the male part so that electrical contact will be made between the probe tip and the metal cap. As the probe pierces the wire trapped between the probe tip cap and the hook, a secure contact is made between the conductive core of the wire and the conductive path from the probe tip to the test equipment.
