ABSTRACT:
The invention relates to a self-cleaning, self-aligning, downhole make and break mechanical and electrical latch subassembly used in conjunction with logging vertical and deviated boreholes. The latch subassembly uses a pair of rings to self-align the male probe into the female receiver. A debris deflector surface and specially sized debris exit ports are provided to allow the mating of the parts without interference from extraneous downhole debris.
