Abstract
A field joint for connecting a plurality of downhole tool modules is disclosed. The modules include a housing and an electrical line. A bulkhead is coupled to a first module that includes a first conduit aperture for receiving an electrical connector assembly. The first electrical connector assembly is releasably coupled to the exterior portion of the first module and includes a first connector having a first end adapted for electrical coupling to an electrical line. A connector block is coupled to the second module that includes a second conduit aperture positioned to substantially face the first conduit aperture when the first and second modules are joined. A second electrical connector is disposed in the second conduit aperture and is electrically coupled to an electrical line such that an electrical contact is established with a second end of the first connector when the first and second modules are joined.
