Internal waterproof type cold contraction intermediate joint

The utility model provides an internal waterproof type cold contraction intermediate joint which is used for connecting cables at two ends. The cold shrinkage intermediate joint comprises a cold shrinkage intermediate joint main insulator, a crimping type connecting pipe, a conductive flexible silica gel belt and an insulating flexible silica gel belt. Two non-communicated cavities are formed in the two ends of the crimping type connecting pipe, and the crimping type connecting pipe is connected with cable cores of cables at the two ends through the two cavities respectively; the conductive flexible silica gel belt wraps a wire core of the cable, the crimping type connecting pipe and an inner semi-conductive layer of the cable. The insulating flexible silica gel belt is coated on the conductive flexible silica gel belt and the insulating reaction force cone of the cable; and the cold shrinkage intermediate joint main insulator is sleeved on the insulating flexible silica gel belt, the insulating layer of the
