The utility model belongs to a hollow polished rod and cable installation connector of an electric heating pumping well, which is used for electric heating pumping wells, serves as a connection device of a cable and a hollow polished rod, and avoids abrasion of a heating cable. The hollow polished rod and cable installation connector of the electric heating pumping well comprises a body, an outer suspension connector, an inner suspension connector, an elbow pipe and a conduit. A cable inserting hole is arranged in the body, the elbow pipe is inserted in an upper inclined hole of the cable inserting hole, a sealing ring is arranged between the outer suspension connector and the inner suspension connector, and abrasion resistant liner tubes are installed in the elbow pipe and a straight hole of the cable inserting hole of the body. The abrasion resistant liner tubes are made of nonmetal materials, the surfaces of the abrasion resistant liner tubes are smooth, and the hardness of the abrasion resistant liner tubes is low. An upper inclined angle of the cable inserting hole is improved. After the heating cable penetrates into the cable inserting hole, the heating cable cannot be abraded when the heating cable and the abrasion resistant liner tubes perform relative movement, thereby prolonging service life of the heating cable.
