ABSTRACT:
The present invention comprises a novel, improved connector mechanism for connecting a probe and a pipe string portion of a wireline based data transmission system. The connector mechanism includes cooperating pin and channel means, one of said means associated with the probe and the other with the pipe string portion. The connector mechanism is especially suited for use in conjunction with a combined tubing conveyed perforating and drill stem testing operations due to the present invention's resistance to unwanted disengagement responsive to jarring or shock waves such as are generated by perforating guns.
