The invention discloses a connection terminal with a cooling function. A cooling channel is arranged in the connection terminal, a cooling medium is circulated in the cooling channel, the heat inside the connection terminal can be taken away by the cooling medium that is continuously circulated in the cooling channel, and thus the temperature of the connection terminal can be reduced. The invention also discloses an electric connection component including the connection terminal. The heat inside an electric connector can be rapidly dissipated by the cooling substance that continuously flows in the cooling channel, and thus the problem of electrical appliance damages and other hidden dangers caused by too high temperature of the electric connection component can be effectively solved.
