CABLE LENGTH CLAMPING DEVICE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention is designed for use in all branches of industry where necessity arises to use length of cable to be fixed with wedging as protective device on objects furnished with eyes for passing cable length to prevent unauthorized penetration and for use as friction clamp for termination of thimbles. Proposed clamping device is provided with insert with through channel to let cable length pass at locking and two slots communicating with channel and designed for accommodating solids of revolution with springs. Slots are arranged at angle relative to each other and at angle to longitudinal axis of insert channel. Side surface of insert, from side on which cable length inlet hole is made, is flat, and two adjoining to flat surface and opposite to each other side surfaces of inserts are made flat also but tilting relative to axis of through hole for cable length. Insert is made of material whose hardness is lower than hardness of material from which housing is made. All external surface of insert is sealed by moistureproof film material. Clamping device is provided with sealing ring to seal cable length inlet in insert. Sealing ring is made of porous material capable of swelling under action of moisture. Seat in form of cradle is made in housing to accommodate insert. Said seat is open from one of flat end face sides of housing. Two side opposite flat walls of cradle have angle of tilting equal to corresponding angle of tilting of insert side walls. Inlet and outlet holes of housing communicate with cradle space, and outer overall dimensions of insert are smaller than overall dimensions of cradle. Longitudinal size of cradle exceeds longitudinal size of insert by preset value of displacement of solids of revolution at closing, and size of its flat side surface pointed to inlet hole of housing is less than size of mating flat side surface of insert from side of which inlet hole for cable length is made. EFFECT: improved reliability, possibility of use under various climatic conditions. 8 cl, 5 dwg
