A method of using an automatic docking device for a cable, characterized in that, A method for using an automatic docking device for a cable according to any one of claims 1-5, comprising the following steps: Installing the protection shell, first abutting the upper protection shell (45) with the first suction plate (443), and abutting the lower protection shell (46) with the second suction plate (445); then using the air pump box (441) to extract the air in the first suction plate (443) and the second suction plate (445), so that a vacuum state is formed between the suction plate and the protection shell to fix the protection shell; Cable positioning, using the cable feeding device (2) to move the cable to the middle of the stripping device (3); Cable stripping, starting the first electric push rod (33) to drive the stripping knife (34) to contact the cable, and then starting the second motor (35), the second motor (35) drives the gear (36) to rotate through the gear (36), and the gear (32) drives the stripping knife (34) to cut the cable through the first electric push rod (33); Cable peeling, using the cable feeding device (2) to retreat the cable, so that the stripping knife (34) blocks the cut cable skin, and separates and cuts the skin; Cable peeling, using the cable feeding device (2) to retreat the cable, so that the stripping knife (34) blocks the cut cable skin, and separates and cuts the skin; To the interface cable, shrink the first electric push rod (33), use the wire sending device (2) to move the two cables to the inside of the lower protective shell (46) and contact, then use the second electric push rod (442) to drive the upper protective shell (45) to interface with the lower protective shell (46), use the external power supply to electrify the inside of the current variable liquid (48), to fix the shape of the upper protective shell (45) and the lower protective shell (46), and then use the upper protective shell (45) and the lower protective shell (46) to extrude and connect the two cables; Reinforce the cable, and inject the conductive solidification gel into the protective shell through the injection hole (455) by the feeding pipe (472); Separate the cable, use the air pump box (441) to input air into the first suction plate (443) and the second suction plate (445), and separate the suction plate from the protective shell.
