A downhole tool for use in measurement-while-drilling applications includes modular ring connectors on opposed ends thereof with the ring connectors being interconnected by a single bus for delivering both power and ground.

Modular connector for measurement-while-drilling tool

An apparatus for nuclear logging is presented. In accordance with the present invention, nuclear detectors and electronic components are all mounted in chambers within the sub wall with covers being removably attached to the chambers. A single bus for delivering both power and signals extends through the sub wall between either end of the tool. This bus terminates at a modular ring connector positioned on each tool end. This tool construction (including sub wall mounted sensors and electronics, single power and signal bus, and ring connectors) is also well suited for other formation evaluation tools used in measurement-while-drilling applications.
