Connector terminal and connector

A connector, comprising:

• a housing;
• a connector terminal installed in the housing, the connector terminal includes:
• a terminal body having a hollow cylindrical part and a plurality of protrusions formed on the hollow cylindrical part, the protrusions are spaced in a circumferential direction of the hollow cylindrical part;
• and
• a supporting component installed on the hollow cylindrical part of the terminal body, the supporting component includes:
• a first circumferential wall having a pair of opposite ends in an axial direction;
• a second circumferential wall coaxial with the first circumferential wall and having a diameter smaller than a diameter of the first circumferential wall;
• a radial wall radially connected between the first circumferential wall and the second circumferential wall;
• and
• a flanging part vertically bent inward from the second circumferential wall at an end of the second circumferential wall opposite the radial wall, the protrusions are constrained between the first circumferential wall, the radial wall, and the flanging part, the radial wall forms a support step;
• and
• an elastic locking piece arranged in the housing, an end of the elastic locking piece is pressed against the radial wall to lock the connector terminal in the housing.
