Electrical engineering cable protection device

The invention discloses an electrical engineering cable protection device which structurally comprises a protection main body, a hinge and an adsorption plate, the hinge is installed at the rear end of the protection main body, the adsorption plate is arranged at the front end of the protection main body, a connecting end of a cable generates more heat, and the generated heat is absorbed through a heat absorption ball in a telescopic hose. The heat absorption balls expand to push the cooling fins to move upwards, heat is dissipated out of the interior of the flip box body, the situation that the flip box body is burnt out after much heat is accumulated is avoided, the attaching pieces formed by the multiple strip-shaped plates freely stretch out and draw back on the penetrating plates, and therefore the lower ends of the attaching pieces abut against and seal the surfaces of the outer sides of the cables. And the extrusion ring drives the sponge pad to extrude the surface of the cable, the sponge pad abuts ag
