1. A high current terminal assembly including a conductor terminal (12), said conductor terminal (12) being operatively arranged to be mounted in an orifice (10 a) in a housing wall (10), and a mounting module (14 a; 14 b) for mounting the conductor terminal (12) to the housing wall (10), said mounting module (14a; 14b) comprising:
a collar structure (16) configured to abut to a first side of said housing wall (10) surrounding said orifice (10 a), and
an insertion part (18) configured to be inserted into the orifice (10 a) of the housing wall (10), wherein a remote end of the insertion part (18) in the insertion direction is provided with first snap-fitting structures (18 a) engaging a second side of said housing wall (10) opposite to the first side of the housing wall, wherein a first end of said conductor terminal (12) is configured to be inserted into an opening of said mounting module (14 a; 14 b) such that engagement of first snap-fitting structures (18 a) with a second side of said housing wall (10) is locked by the insertion of said first end of said conductor terminal (12);
wherein the remote end of the conductor terminal (12) is configured to deflect the ends of the snap-fitting structures (18 a) radially outward when being inserted into the opening of said mounting module (14 a; 14 b) and includes a plurality of recessed step portions (12 a, 12 a′) for accommodating the ends of the snap-fitting structures (18 a) when the conductor terminal (12) has reached its final insertion position; and
wherein the plurality of recessed step portions (12 a′) each accommodate the end of one of the snap-fitting structures (18 a) in specific ranges of angular orientations with a sloped surface (12 f) extending from each of the recessed step portions (12 a′) in at least one circumferential direction such that the engagement between the plurality of recessed step portion (12 a, 12 a′) and the snap-fitting structures (18 a) is releasable by rotating the conductor terminal (12).
