This is a collection of solid models and drawings of the NOvA optical connector used on the far detector. The connector consists of two separate parts,, "opt_conn_7" and "opt_conn_back_7", which are ultrasonically welded together. The assembly is represented in "opt_conn_7_asm".

Notes and Changes:
1) Draft angle and step added to back surface of opt_conn_7 to improve seal of epoxy injection channel with snout back. 2) Dowel pin hole & slot diameters increased to 2.512/2.532 to eliminate chance for force fit developing when thermoelectric cooler is activated. 3) Bottom fillet radius of dowel pin hole and slot changed from 0.3 mm max to 0.3 mm nominal to reduce stress concentration there.
