1. A unipolar connection terminal for a connector, comprising: a columnar insertion tube configured to be connected and passed through by a mating terminal, an end portion of the insertion tube extends in a radial direction to form at least three protrusion structures, the at least three protrusion structures are arranged at intervals in a circumferential direction of an end surface of the insertion tube, wherein at least one of the protrusion structures is a first fool-proof protrusion, and at least two of the protrusion structures are second fool-proof protrusions, and a cross-sectional area of the first fool-proof protrusion is greater than a cross-sectional area of any one of the second fool-proof protrusions wherein distances between the first fool-proof protrusion and the second fool-proof protrusions are identical.
