Abstract: A universal cable head is set forth which incorporates a stress relieving stinger on the end of a logging cable. The cable connects with wedge shaped members which grip the end of a cable within a housing. Electrical conductors, seven in number, extend from the end of the cable into the housing and are exposed in an internal cavity. In the cavity, they connect with a set of boots at the back end connecting with feedthrus by bayonet connection, the feedthrus being supported on a transverse bulkhead, and the feedthrus all extend through the bulkhead to locate male plugs within a circular housing. A rotatable threaded sleeve is on the exterior for connection with a mating female member. All of this structure connects universally to mating female connectors on downhole logging tools to provide the requisite number of conductors for downhole logging operations.

Abstract: To provide for reliably sealing conductors or cables into a plug connector housing, the plug connector housing is formed with bores (2) in each of which a sealing bushing or sleeve (5) is located surrounding the outer insulating jacket (3a) of the conductor or cable. To protect the seals and prevent distortion and damage to the seals upon bending of the cables, and end seating and retaining part is received in an end recess (9) of the housing . The end seating and retaining part, in accordance with the invention, is formed of two half elements (11, 12) which surround the cables (3) and extend through the recess (9) from the bores (2) towards the end of the housing. The two elements (11, 12), each, are retained in the housing by a projection-and-recess snap-in connection (21, 23; 22, 24), and the two elements permit easy assembly which can be automated for mass production.

Abstract: An electrical receptacle terminal having a longitudinal body for receiving a pin terminal includes a bifurcated beam spring forming two spring arms. The two spring arms act independently to urge an inserted pin terminal into good electrical contact with an opposing rib formed in an opposing wall. Each spring arm also includes a respective side flange which is contoured to engage the pin terminal in quadrature with the spring arms and rib. The pair of flanges have opposed faces for engaging opposite sides of the pin terminal. The spacing of the opposed faces of the flanges is normally less than the dimension of the pin terminal they engage such that they and the spring arms are resiliently spread by the pin terminal to thereby provide secure engagement. The four walls of the receptacle terminal are folded inward and rearward to form a continuous entry aperture and also to provide the spring arms.

Abstract: A modular connector includes a housing (18, 181, 191, 518) having an interior surface adapted to engage a mating external surface of one or more contact-receiving and -carrying modules (20, 210, 520, 521) supported within the housing. The wire contacts (64, 65, 66, 600) are removably supported within the module to permit one or more contacts to be removed and replaced without destruction of the entire module. Mating structures of the housing and the module and the contacts repeatably position the housing portions with respect to one another and precisely position the module within the housing laterally, longitudinally, and vertically and precisely position the contacts within the module. The invention also includes a module (520, 521) having an integral sealing boot (578) formed thereon to provide strain relief and effective sealing around the conductor wires (536, 537) entering into the module and between the module and the housing portions.

Abstract: A sealed electrical connector has a housing receiving terminated conductors therein, for mating to a corresponding connector. A camming member is latched to the rear of the housing with bores therethrough through which the conductors extend. Wire seals are disposed between the housing and the camming member around each conductor. A sequential latching provides a first or open position for the camming member which allows for insertion of the terminated conductors through bores of the camming member, through respective wire seals and into respective passageways of the housing wherein the terminals are seated. The camming member is then moved axially forward to a second or closed position which cams against the rear sections of the wire seals and urges and deforms them radially inwardly against the conductors so that a pressure-resistant seal is formed between the conductor, the wire seal, and the camming member. Several types of wire seals are usable with the sealed connector.
