The invention discloses a cable lead-in compression device. The cable lead-in compression device comprises a compression nut type cable lead-in device and is further provided with a split type detachable cable falling-off prevention device. The compression nut type cable lead-in device comprises a compression nut, a pressure ring, a seal ring and a closed tube. The seal ring is arranged on the inner side of the closed tube. The pressure ring is arranged on the outer side of the seal ring and closely attached to the seal ring. The compression nut is arranged on the side, where a cable is led in, of the closed tube. The cable falling-off prevention device comprises two wire pressing strips and an ox horn type fixing ring fixed to the compression nut through a bolt, and the two wire pressing strips are fixed to the ox horn type fixing ring through bolts and nuts and used for clamping and fixing the cable to prevent loosening. As the cable falling-off prevention device is additionally arranged, the situation that the cable loosens during use can be effectively prevented, and safety is improved.
Description
technical field [0001] The invention belongs to the field of explosion-proof electrical equipment, and in particular relates to a cable lead-in compression device. Background technique [0002] Explosion-proof electrical equipment introduction compression device is a device that introduces cables into electrical equipment without changing the explosion-proof performance of the equipment's explosion-proof form. The main component of the existing explosion-proof electrical equipment (explosion-proof cable connector) is a compression nut type cable entry device. The compression nut type cable entry device mainly includes a compression nut, a compression ring, a sealing ring, and a communication pipe. The sealing ring and the compression ring are arranged in the connecting pipe, the compression ring supports the sealing ring from one side, and the compression nut is sleeved on the outside of the compression ring. When the cable is connected, the compression nut exerts pressure...
