ABSTRACT:
A resilient tapered conical insert (40,70) is snap fit into a mating recess in each side of a two-piece multi-circuit connector (50, 80). A coupling body segmented latch arm (501, 801) expands over an insert ramp (410, 701) with segmented tabs (42, 82) and locks into an insert recess groove (402, 702) for a tactile and audible signal of engagement and a secure permanent union. Replaceable contact elements (20, 90) are snap fit in a fluid-resistant self-sealing relationship to selected mating openings (44, 74) in the inserts with a contact protrusion (22, 92) engaging an insert shoulder (140, 170) and contact barbs (23, 93) engaging resilient insert openings (145A, 171). A front contact barb (24, 94) snaps into a larger insert opening (45, 74) for a tactile and audible feedback of complete insertion. Replaceable inserts may be fitted with any desired configuration of paired contact elements assembled in the field. Blank or partially blank inserts (40B, 70B) may be drilled in the field.
