Disclosed is a packing structure for waterproofing a cable inlet of an optical terminal box. The packing structure has a soft pressure waterproof unit formed at a hard holder housing through double injection, thereby firmly pressurizing a cable which is introduced or drawn out to be fixed when the cable is introduced or drawn out through a cable inlet of an optical terminal box, preventing a foreign material, rainwater, moisture, or the like from being introduced into the optical terminal box, which may affect electrical properties of the optical terminal box to perform connection and distribution functions between an external optical line and a subscriber transmitting device while eliminating cracks in a contact surface between the cable inlet and the packing structure and in a contact surface between the packing structure and the cable; and improving convenience of maintenance by allowing the packing structure to be easily disassembled to replace or repair the cable or parts of the optical terminal box. |
