Abstract

A compact cable distribution box comprises a base, two side plates, two or more cable fixators, a shield and a branching device, wherein the shield includes a first half shield and a second half shield which are detachably connected, and the branching device positioned in the shield is used for branching tributary lines from a core wire of a main cable. Mounting of the cable distribution box on a laid cable under the condition that the main cable is not cut off can be realized as the side plate, the cable fixators and the shield are in two-piece structures. Moreover, after the main cable is fixed by the compact cable distribution box by the aid of the cable fixators, stereoscopic branching of the core wire inside the box can be realized, and the branching device is flexibly arranged so that the size of the cable distribution box can be decreased to facilitate mounting in construction, which is especially suitable for a vertical shaft with a limited construction range, and simultaneously conductor deformation in branching is decreased. Further, flame retardant rating can be recovered when an unsheathed cable segment is protected by the shield.
