The invention relates to electrical equipment, in particular, to explosion-proof cable inputs used in mining industry and productions having explosive atmosphere associated with gases, vapors and dust.The invention is aimed at developing a small-sized quick-release cable input providing maximum reliability of cable fixing using a sealing ring.The inventive device is characterized in that a cable passageway comprises a detachable casing for cable (1) arrangement consisting of an input body (5) having a face cavity for mounting fixture to an electrical equipment, and nuts (6) with a face recess for thread connection to the input body, a sealing ring (2) and two conical sleeves (3, 4) for interacting with the sealing ring, the first sleeve is arranged in the input body face cavity, the second in the nut face recess, the second sleeve contacts the input body face cavity adapted to possible longitudinal displacement in the first sleeve at nut rotation to exert a compression action upon the sealing ring and fixing the cable in the cable passage casing.There are some other differences from a prototype.The proposed device of the quick-release cable input provides maximum reliability of cable fixing using a sealing ring and small-size parts of the device. |
