Abstract: The invention relates to a connector (10) for high amperage electric crossing (11) including at least one pin (12) having a first main axis (13). The connector (10) comprises a first assembly including a socket (15) having a second main axis (16) and a first insulator (21) intended to cover at least partially the socket (15). According to the invention, the first assembly comprises a cap (22) including a recess centred (23) on the second main axis (16) of the socket (15) and locking means (24) to attach the cap (22) to the first insulator (21). The connector (10) comprises moreover a second assembly including a second insulator (28) and fastening means (29) to attach the second insulator (28) to the electric crossing (11), said second insulator (28) surrounding said pin (12) and including at least one recess centred on the first main axis (13) to receive the first insulator (21) when inserting the socket (15) into the pin (12).
