Coupling for a threaded connection

Abstract

A coupling for a threaded connection is provided. The coupling comprises: a tubular main body with first and second ends. Each end has a box with an inner surface on which is formed a female thread for engagement with a pin of a tubular component. The coupling further comprises: a first female electrical contact on the inner surface of the first end, and insulated from the tubular main body; a second female electrical contact on the inner surface of the second end, and insulated from the tubular main body; and a longitudinal conductor in communication with the first and second female electrical contacts, and insulated from the tubular main body. The tubular main body has formed therein a longitudinally-extending bore, through which the longitudinal conductor extends.
