The invention relates to a training method and device of a contact resistance prediction model and computer equipment. The method comprises the following steps: acquiring heat transfer characteristic information of each piece of structural information of the cable joint, temperature field characteristic information of each piece of structural information and contact resistance equivalent characteristic information of each piece of structural information; based on the above information, screening target structure information in each piece of structure information, and based on each piece of target structure information, establishing an initial contact resistance prediction model; determining model parameters of the initial contact resistance prediction model based on the temperature data of each sample, the contact resistance of the sample and a parameter optimization algorithm; and based on the sample contact resistance, the model parameters of the initial contact resistance prediction model and the model sel
