ELASTIC FORMED LONGITUDINAL LID Russian patent published in 2005 - IPC

FIELD: the invention refers to the field of electro technique and touches upon the peculiarities of constructive making of the products out of the rolled metal used in quality of an armature for extended cable lines particularly for communication lines used at installing of signaling, special facilities and other service equipment.

SUBSTANCE: the essence of the invention is in that elastic formed longitudinal lid has lengthwise a C-shaped profile with located opposite sharp-cornered lugs on the butt-ends having radius curving. On the surface of the lid there is at least one trapezoidal lug with radius transitions of coupling with the plates of the lid. The sides of the butt-ends of the lid are directed under an angle providing a space gap relatively to the surface of abutment to the radius profile formed by the mentioned sharp-cornered lugs. At that according to this invention interior lugs of h height having radius couplings with the plates of the lid providing enhanced solidity to its construction are fulfilled across the width of the C-shaped profile from the side of the butt-ends of the lid.

EFFECT: simplification of the construction, enhancing solidity, decreasing material consumption and increasing manufacturability of elastic formed longitudinal lid.
