ABSTRACT:
A connector assembly adapted to quickly connect and disconnect tools and stem sections in wireline tool strings. Connector assembly (10) comprises box end (12) and pin end (14) adapted to be slidably engaged and locked by rotating either end 90.degree. relative to the other in either direction. Connector assembly (10) is released by the direct application of manual force to ears (48, 50) of locking plate (38) accessible in flutes (26, 27) of box end (12). Once the locking plate is retracted, pin end (14) is rotated 90.degree. in either direction relative to box end (12) and then withdrawn axially from box end (12). Flats (130, 131) are provided on box end (126) and pin end (128) to indicate relative rotational alignment. Disclosed also are provisions for limiting the rotation of axially spaced lugs (138, 140) before the lugs are axially aligned with annular channels (142, 144).
