Cable joint with overload protection structure

The invention relates to the technical field of cable joints, in particular to a cable joint with an overload protection structure. Comprising symmetrically-distributed sleeves, the symmetrically-distributed sleeves are hinged to each other, symmetrically-distributed first connecting pipes are fixedly connected to the middle of the interior of one of the sleeves, the opposite sides of the symmetrically-distributed first connecting pipes are slidably connected with contact pieces, symmetrically-distributed first hydraulic shells are fixedly connected to the interior of the sleeve fixedly connected with the first connecting pipes, and the first hydraulic shells are fixedly connected to the interior of the sleeve fixedly connected with the first connecting pipes. The first hydraulic shells are slidably connected with second connecting pipes slidably connected with the symmetrically-distributed sleeves, the second connecting pipes are fixedly connected with piston plates slidably connected with the adjacent first
