The invention relates to an electric connecting apparatus and a touch finger base therefor. The electric connecting apparatus comprises a contact finger base and a conductive rod, wherein the contact finger base comprises a conductor and a shielding cover arranged on the periphery of the conductor; an inserting space for allowing the corresponding conductive rod to be inserted from top to bottom is formed between the conductor and the shielding cover; a shielding cover matching surface section is arranged at the lower end of the inner hole wall of the shielding cover; and a conductor matching surface section that is in interference fit with the shielding cover matching surface section is arranged at the lower end of the outer peripheral surface of the conductor. The shielding cover matching surface section is in interference fit with the conductor matching surface section, so that the connection between the shielding cover and the conductor is realized; therefore, a mounting space for mounting a screw connecting structure is not required to be reserved; the influence on the requirement of an electric field from the screw connecting structure is not required to be considered; the problems of low efficiency and low rate of finished products in welding also can be prevented; and therefore, the contact finger base provided by the invention is good in technology, simple in structure and convenient to popularize and apply.
