A connector (10) used with a high-current terminal (100) includes a main body (1) and a conductive spacer (2). The main body (1) has a connecting portion (11) disposed at one end thereof and a pluggable portion (12) disposed at the other end thereof. The high-current terminal (100) is plugged into the pluggable portion (12). The conductive spacer (2) is disposed between the pluggable portion (12) and the high-current terminal (100). The conductive spacer (2) has a plurality of outer projections (21) pressed against the pluggable portion (12) and a plurality of inner projections (22) pressed against the high-current terminal (100). Thus, the number of electrical contact points is increased by means of the outer projections (21) and the inner projections (22) disposed between the pluggable portion (12) and the high-current terminal (100) such that the connector (10) has excellent electric conductivity and current adjustment capability.
