Abstract
A rope socket assembly, wireline logging heads that include the rope socket assembly, and processes for assembling same. In some examples, the rope socket assembly for a wireline logging head can include a housing, a retainer, a rope socket, a separator, a seal, a pressure cap, a sleeve, a pressure compensating piston at least partially disposed about the sleeve, an electrical bulkhead housing disposed within the sleeve, and a conductor bundle disposed within the electrical bulkhead housing. The conductor bundle can include a plurality of terminals configured to receive a plurality of wires from a wireline and form an electrical connection therebetween. Each terminal can be configured to seal a terminal end of one of the plurality of wires from the wireline.

A rope socket assembly for a wireline logging head, comprising:
- a housing comprising a body having a bore formed therethrough and an end cap coupled to a first end of the body;
- a retainer at least partially disposed within the bore proximate a second end of the body, wherein the retainer is configured to secure a wireline therein, the wireline comprising a plurality of individual wires;
- a rope socket disposed within the bore and having a first end and a second end, wherein the first end of the rope socket is adjacent the retainer, and wherein the rope socket is configured to receive the plurality of individual wires;
- a separator at least partially disposed within the rope socket and configured to separate the plurality of individual wires;
- a seal at least partially disposed within the rope socket;
- a pressure cap coupled to the second end of the rope socket, thereby compressing the seal and retaining the separator at least partially within the rope socket;
