CABLE LENGTH CLAMPING DEVICE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in different branches of industry where cable lengths are to be fastened on objects provided with eyes. Proposed invention has body and cable length made of steel which can be passed through eyes of object to be protected. One end of cable is preliminarily rigidly secured in body by means of fitted unit and second end of cable is clamped in locking device found on body after locking. Clamping device has electronic mark located on body and made for transmission of signal is case of violation of integrity of cable, and first and second magnetoresistive sensors. Outputs of magnetoresistive sensors are connected with check unit in electronic mark or made in form of separate electronic unit electrically coupled with electronic mark. Magnet with through hole is located in body near fitting unit of cable first end. Cable length is passed through said hole. Coercitive force of magnet provides creating of magnetic flux closing over loop of cable length arranged outside the body through body, and second end of cable at locking is laid successively in first magnetoresistive sensor, locking device and second magnetoresistive sensor. Invention is aimed at improving reliability at remote control of integrity of cable length. EFFECT: operative prevention of unauthorized access to protected objects. 1 dwg
