Smith, L J; Wood, D R

A modular connector is described for interconnecting a downhole tool adapted to be disposed in a wellbore with an elongated tubing string, the tubing string including an elongated signal transmitting cable extending therein for transmitting signals between the tool and the earth's surface. The connector consists of an elongated body member connected at one end to the tubing string, the body member including means forming a bore through which the cable extends; and a swivel coupling interconnecting the body member with the tool to permit lateral displacement of the tool relative to the tubing string, the swivel coupling including a generally spherical coupling member secured in a socket in a coupling body, the spherical coupling member and the coupling body including passage means for extending electrical conductors between the connector and the tool through the swivel coupling.
