    Abstract: A threaded connection is provided. The threaded connection comprises: first and second tubular components. The first tubular component comprises: at a first end region a pin with an outer surface on which is formed a male thread; and an opposite second end region. The second tubular component comprises: at a first end region a box with an inner surface on which is formed a female thread; and an opposite second end region. The male thread is arranged to engage the female thread in a made-up configuration. A male electrical contact is provided on the outer surface of the first end region of the first tubular component and insulated from the first tubular component. A female electrical contact is provided on the inner surface of the first end region of the second tubular component and insulated from the second tubular component. A first conductor extends along the outer surface of the first tubular component, in communication with the male electrical contact, and insulated from the first tubular component. A second conductor extends along the second tubular component, in communication with the female electrical contact, and insulated from the second tubular component. The male and female electrical contacts are arranged to contact with each other in the made-up configuration. The male electrical contact has a width in an axial direction of the first tubular component and the female electrical contact has a width in an axial direction of the second tubular component. The width of the female electrical contact is smaller than the width of the male electrical contact, or vice versa.
