Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
A universal cable head which comprises: (a) an armored logging cable having up to seven electrical conductors therein and incorporating a woven wire rope, and a surrounding armor wrap; (b) stress relieving stinger means on said cable; (c) an encircling housing on the end of said cable having an external shoulder thereon connecting with said stress relieving stinger to transfer axial loads from said cable to said housing; (d) an internal transverse bulkhead within said housing adjacent to an internal cavity therein; (e) electrical feedthrus supported by said transverse bulkhead, said feedthrus having a cable end formed with terminals for connection of conductors in said logging cable; (f) exposed mating connectors in a prearranged pattern supported by said bulkhead, said connectors being electrically connected to said feedthrus; (g) said housing extending past and encircling said mating connectors; and (h) a rotatable, shoulder limited sleeve on the exterior of said housing having threading means thereon for connecting with a mating female connector.
Claim 2
Dependent Claim
161 words
A universal cable head which comprises: (a) an armored logging cable having up to seven electrical conductors therein and incorporating a woven wire rope, and a surrounding armor wrap; (b) stress relieving stinger means on said cable; (c) an encircling housing on the end of said cable having an external shoulder thereon connecting with said stress relieving stinger to transfer axial loads from said cable to said housing; (d) an internal transverse bulkhead within said housing adjacent to an internal cavity therein; (e) electrical feedthrus supported by said transverse bulkhead, said feedthrus having a cable end formed with terminals for connection of conductors in said logging cable; (f) exposed mating connectors in a prearranged pattern supported by said bulkhead, said connectors being electrically connected to said feedthrus; (g) said housing extending past and encircling said mating connectors; and (h) a rotatable, shoulder limited sleeve on the exterior of said housing having threading means thereon for connecting with a mating female connector.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 wherein said feedthrus incorporate locking nuts thereon anchoring said feedthrus on said bulkhead, and thereby position exposed terminals in said cavity and further including boots mounting on bayonet motion over said feedthrus.
Claim 4
Dependent Claim
33 words
The apparatus of claim 1 wherein said stinger terminates at an encircling collar about a portion of said housing and grips said housing to transfer stress from said logging cable into said housing.
Claim 5
Dependent Claim
14 words
The apparatus of claim 3 wherein said stinger and said housing are clamped together.
Claim 6
Dependent Claim
81 words
A female connector for mating with the male connector of claim 1 wherein the female connector incorporates a cylindrical solid body having a set of feedthrus mounted therein, wherein said feedthrus terminate at female sockets matching in number and placement the male connectors on the feedthru of said electrical connector, and further wherein said solid body supports said female feedthrus with exposed electrical terminals within a cavity within a surrounding housing to permit electrical conductors to be connected to said feedthrus.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1 wherein stress relieving stinger means is secured to said housing by a clamp means.
Claim 8
Dependent Claim
29 words
The apparatus of claim 1 wherein said housing is divided into spaced chambers by said bulkhead, and said feedthrus form two ends, said ends located in said spaced chambers.
Claim 9
Dependent Claim
31 words
The apparatus of claim 7 wherein one of said chambers encloses a boot termination on a conductor of the logging cable, and the other of said chambers encloses said mating connectors.
Claim 10
Dependent Claim
19 words
The apparatus of claim 8 including a fixed portion of said feedthrus and detachable portion enclosed within said boot.
Claim 11
Dependent Claim
52 words
The apparatus of claim 1 wherein said sleeve is: (a) releasably locked in position by a removable bolt means; (c) concentric about said housing; (c) limited in axial movement relative to said housing by a shoulder; (d) longer than said housing; and (e) internally threaded to connect to a mating female connector.
