The cable passing portion 31 is provided on the sealing member 3, allows the cable 5 to pass therethrough, and seals the cable 5.

Alternatively, when the thickness of the sealing member 3 is thin, the cable passing portion 31 may have only a preformed hole, which may be, for example, a cross opening or a dot-break type through hole or the like.

Alternatively, the cross-shaped opening is cut in a predetermined length in a cross shape at a predetermined position of the sealing member 3 using a tool, and after being cut, the predetermined position is divided into four parts separated from each other, and when an external force is applied, the four parts separated from each other are elastically deformed in the same direction such that a central portion thereof is exposed as a through-hole. Specifically, according to the embodiment of the present invention, when the cable 5 needs to pass through the cable passing portion 31, as the cable 5 penetrates, an external force is generated to the cross-shaped opening, and each portion separated from each other by the cross-shaped opening may have approximately uniform elastic deformation toward a direction in which the cable 5 passes, so that the central portion of the cable passing portion 31 is exposed as a through hole for the cable 5 to pass through; when no cable 5 passes through, the four parts separated from each other are not deformed and keep the original positions, and play the roles of sealing and isolating. Alternatively, the predetermined length cut by the cross-shaped opening may correspond to the diameter of the cable 5 to be passed through, so that the size of the through hole exposed at the central portion of the cable passing portion 31 is slightly smaller than the diameter of the cable 5 to be passed through. When the cable 5 passes through, the material around the through hole exposed by the cable passing part 31 generates proper elastic deformation, and the cable 5 is extruded, so that the cable 5 can be tightly attached to the parts of the cable passing part 31, which generate elastic deformation, and sealing is realized.

Alternatively, the dot-break through hole is a closed pattern in which the periphery of a predetermined position of the sealing member 3 is arranged to have a spaced-apart break shape, which can be broken as needed, thereby exposing the closed pattern as a through hole. Specifically, according to an embodiment of the present invention, when a cable needs to pass through the cable passing portion 31, the closed pattern of the sealing member 3 may be broken using a person or with a tool so that a central portion of the closed pattern is exposed to pass through the cable 5; when no cable 5 passes through, the closing pattern remains in place, serving as a seal and isolation. Alternatively, the size of the encapsulation pattern may correspond to the diameter of the cable 5 being passed through, such that the size of the through hole exposed after removal of the encapsulation pattern is slightly smaller than the diameter of the cable 5 being passed through. When the cable 5 passes through, the material around the through hole exposed by the cable passing part 31 generates proper elastic deformation, and the cable 5 is extruded, so that the cable 5 can be tightly attached to the parts of the cable passing part 31, which generate elastic deformation, and sealing is realized.

Alternatively, the form of the preformed hole of the present invention is not limited to this, and may be a form of a preformed hole having a cross-shaped through hole formed by removing a portion of the material on the sealing member 3 along the cross shape.

That is, a part of the material of the cable passage portion 31 may be cut in advance to reduce the thickness of a preformed hole such as a cross opening or a dot-and-dash type through hole, thereby allowing the cable 5 to pass through the sealing member 3 more smoothly. The blind hole H3 can expose all the prefabricated holes such as cross opening or dot-broken through hole. The shape of the blind hole H3 may preferably be circular and have a diameter larger than the diameter of the cable 5 to be passed through. However, the shape of the blind hole H3 of the present invention is not limited thereto, as long as the prefabricated hole in the form of a cross opening or a dot-and-dash type through hole or the like can be entirely exposed and does not affect the passage of the cable 5.

According to the embodiment of the present invention, the sealing member 3 may be formed using a material having elasticity, preferably, rubber, polyurethane, or the like. The sealing member 3 may also be made of a fireproof material having a certain elasticity, thereby achieving a function of isolating the spread of fire.
