CLAMP FOR CABLE AND CASE FOR TELECOMMUNICATIONS Russian patent published in 2017 - IPC G02B6/44 

FIELD: physics.

SUBSTANCE: claimed case for telecommunications (10) comprises cables (46), a cover (20), an inner frame (30), a frame (30) holding telecommunication equipment (32), and a sealing block (40) sealing the closed cover (20) with respect to one or more cables (46) entering the case (10). The frame (30) limits a plurality of clamping device holders (36). A plurality of clamping devices (60, 160, 260) are provided, each clamping device (60, 160, 260) being designed to hold a cable including a sheath (48), internal optical fibres (52), and, at least, one internal reinforcing element (50). Each cable clamping device (60, 160, 260) includes a clamping device (64, 164, 264) movable with respect to the frame, including a clamp (68) adapted to be fastened around the case, and a clamping device (80, 180, 280) for the reinforcing element, movable with respect to the frame. The yoke (68) extends around the frame (48) and is adjustable to match the different frame diameters. The clamping device (80, 180, 280) for the reinforcing element is configured to be positioned at different positions with respect to the clamping device (64, 164, 264) for taking into account changes in the relative position of the reinforcing element (50) with respect to the clamping device for the frame. The clamping device (60, 160, 260) is movable with respect to the frame (30), wherein the cable (46) is movable in the desired position with respect to the sealing block (40) so as to reduce the likelihood of leakage at the central positioning relative to the cable hole through the sealing block.

EFFECT: simplification of the design, due to which it is possible to clamp the frames of various sizes and reinforcing elements.
