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.

Abstract: A connector system comprising a first connector body comprising a housing and a collar. The housing comprising at least one cam recess having an innermost portion and an outermost portion. The collar comprises a first end having at least one engagement boss and a second end having at least one rotational rib member which is elastically deformable. The rotational rib member comprises a cam follower portion. The collar being resistingly rotatable about the housing as the cam follower portion is slidingly moveable from the innermost portion to the outermost portion of the cam recess causing the rotational rib member to become increasingly elastically deformed. The connector system further comprises a second connector body comprising at least one engagement recess having a tapered wall portion and a locking portion.

Abstract: A socket for a high voltage plug is folded from a single sheet of metal to form a cylindrical corona shield on an axis about a pair of spring contacts. The shield and contacts extend from a cylindrical base of the shield along a solder face to an outer segmental lip for suppressing corona from wiring on the face.
