Patent ID: 6926098

Claim:
A gap sub assembly for use within a drill string to transmit data sensed by a measurement-while-drilling tool to an external receiver, the gap sub assembly comprising: a tubular upper gap sub defining an axial borespace within; a tubular lower sub defining an axial borespace within; the upper and lower subs being interconnected by an insulated connection to preclude transmission of an electrical signal between the upper and lower subs, the insulated connection being in an area sealed from the borespaces of the upper and lower gap subs; an electrical conductor assembly retained within the insulated connection in electrical contact with the upper gap sub within the sealed area for transmitting en electrical signal from a measurement-while-drilling tool to the upper gap sub and to the lower sub, the electrical conductor assembly comprising: a contact member to contact a portion of the upper gap sub; and a pressure plug in electrical contact with the contact member, the pressure plug shaped and sized to prevent entrance of fluids into a non-conductive housing.
