FIELD: electric engineering. ^ SUBSTANCE: invention may be used in any engineering branches for electric cable fastening and routing, especially, for high-voltage electric cable fastening to the instrument housing. There is a graded slot with large diameter step made in the instrument housing. The fastening element is implemented as plug with diametrical side extensions. The chamfered extensions contact with slot walls when plug is installed. The chamfers are made at no more than 30 angle. There are open-end grooves made in the plug comparable to cable diameter by height and to plug extensions by width. The grooves are located at both sides from cable. Besides, the plug height does not exceed the groove depth. The plug is inserted into groove with pre-routed cable. Two longitudinal open-end slots are made on the upper surface of plug and under side grooves. The plug is produced by hot pressing method with one or more grooves being intended for electrical cabling. ^ EFFECT: improved reliability of high-voltage cable integrity at any spatial positions of instrument; cable is within limited space of instrument housing without any extensions, cable is fastened to instrument housing due to simple fastening technology avoiding cable pre-deformation and excluding mechanical damage of high-voltage electric cable. ^ 2 cl, 2 dwg |
