Abstract
A two plate, TXV block type of connector for an automotive air conditioning system evaporator improves the security and serviceability of the connection through the use of common bolts specially designed to cooperate with matching bolt passages through the TXV valve block. The evaporator side anchor plate threads to one end of the bolts first, and is pulled tight to one side of the block as enlarged flanges on the bolts are concurrently pulled tight against a recessed shoulder in the bolt passage. Matching conical shapes on the bolt flange and bolt passage shoulder, coupled with a radial clearance between the rest of the bolt and the bolt passage, self center the bolt and compensates for any initial misalignment. The bolts protruded enough to allow the second plate to be attached, or removed later, independently, with nuts that are threaded on from the same direction.
