The invention discloses a silicone rubber cable terminal with a good sealing effect, wherein insulating tubes and a tri-finger guard are overlapped fixedly. The silicone rubber cable terminal provided in the invention comprises a tri-finger guard, insulating tubes, terminal bodies, and sealed tubes. An inner wall is compounded with electric stresses tubes, wherein the inner wall is in each terminal body and is at a place approaching one end of the each terminal body. Insulating tubes are contracted at a cable copper shield layer; one end of each insulating tube is overlapped with the tri-finger guard, and the other end of the each insulating tube is overlapped and contracted in the one end of one terminal body, wherein the one end is compounded with the electric stresses tubes. One end of each sealed tube is overlapped with the other end of the each terminal body, wherein the other end is far from the one end compounded with the electric stresses tubes. Reinforcement fastening wires are respectively arranged at two end of each insulating tube; a positioning ring of installation dimension is arranged near one of reinforcement fastening wires of the each insulating tube, wherein the one reinforcement fastening wire approaches the one end of the terminal body and the one end is contracted in the one end of the one terminal body. At least one reinforcement fastening and sealing wire is arranged at the one end of the each sealed tube, wherein the one end is overlapped with the one terminal body. Reinforcement sealing wires are respectively arranged at two ends of the each sealed tube. The silicone rubber cable terminal is mainly applied to connection of a cable and a switch in the power cable industry.
Description
technical field [0001] The invention relates to a power cable terminal, in particular to a cable silicone rubber terminal comprising a three-finger sleeve, an insulating tube, a terminal body and a sealing tube. Background technique [0002] Cable silicone rubber terminals are mainly used in the connection between cables and switches in the power cable industry. The current cable terminals mainly include three-finger sleeves, insulating tubes, terminal bodies and sealing tubes. The terminal body is on the inner wall near the end of the terminal body. It is compounded with an electric stress tube; the insulating tube is shrunk on the copper shielding layer of the cable, one end of which is overlapped with the three-finger sleeve, and the other end is overlapped and shrunk in one end of the terminal body compounded with the electric stress tube. One end of the tube is lapped on the other end away from the terminal body compounded with the electrical stress tube. The cable ter...
