The O-ring is configured to maintain the airtightness of the cable gland 10, and the sealing groove 16 prevents the O-ring from deviating and stably connects the O-ring to the body 10.

At least one region can be inserted into the body portion 10 of the packing portion 20 and a receiving groove 21 for fixing the cable can be formed. The packing part 20 can be pressed against the outer circumferential surface of the cable while the diameter of the receiving groove 21 of the packing part 20 becomes narrower as the body part 10 and the nut part 40 are combined. For this purpose, the packing portion 20 may be formed of various materials having an elastic restoring force. In one embodiment, the packing portion 20 may be formed of a silicone material that is reshaped when the external force is removed. The silicone material not only has excellent waterproof performance but also has a high elastic restoring force and can be restored to its original shape when the force applied to the packing portion 20 is removed. As a result, the packing unit 20 can be reused many times, thereby reducing the cost and waste of resources. In addition, the silicone material is easy to shrink and expand, so that the accommodating groove 21 of the packing portion 20 can be adjusted correspondingly to a cable of various diameters.

1B, the packing portion 20 may be formed in such a shape that the diameter of the outer peripheral surface gradually decreases from the front end A to the rear end B, and the inner peripheral surface of the nut coupling portion 11 And may be formed in an inclined shape corresponding to the shape of the packing part 20 as described above. In addition, the packing portion 20 may be formed in a shape inclined with the upper edge 22 being curved. The function and effect according to the shape of the packing portion 20 will be further described in detail with reference to Fig.

The washer portion 30 may be disposed between one end of the packing portion 20 and the nut portion 40 and the frictional force of the surface of the washer portion 30 may be smaller than the frictional force of the surface of the packing portion 20. To this end, the washer portion 30 may be formed as a smooth surface, and may be formed in the form of a ring having a step 31 on the upper end thereof. Specifically, when the nut portion 40 rotates and is threadedly engaged with the body portion 10, the washer portion 30 is positioned at one end of the packing portion 20 so that the packing portion 20 20 can be prevented from rotating. The washer portion 20 prevents the packing portion 20 from being damaged by the nut portion 40 and prevents the one portion of the packing portion 20 from protruding outside the nut portion 40 . For example, the washer portion 30 may be formed of a hard plastic material having a smooth surface, and may be modified into various materials in accordance with the characteristics of the washer portion 30 as described above.

 The nut portion 40 may be coupled to the nut coupling portion 11, which is one end of the body portion 10. Female threads 41 may be formed on the inner circumferential surface of the nut portion 40 and may be threadedly engaged with the first male threads 14 of the threaded portion 11. A washer 30 may be received in the nut 40 and a receiving groove 42 for receiving the step 31 of the washer 30 may be formed at one end of the nut 40 . For example, the nut portion 40 may be formed of a hard metal material having corrosion resistance that does not cause corrosion, and may be variously changed within a range known to a person skilled in the art.

FIG. 2 illustrates a process of fastening a cable gland according to an embodiment of the present invention.

FIG. 2 (a) shows a state before a nut portion of a cable gland is fastened to a body portion according to an embodiment of the present invention, and FIG. 2 (b) And the state after the part is fastened to the body part.

2, the packing part 20 can be received in the body part 10 as the screw connection of the nut coupling part 11 and the nut part 40 progresses. Specifically, as the nut portion 40 presses the packing portion 20, the packing portion 20 can be simultaneously contracted while moving toward the inner peripheral surface of the fastening portion 13. The diameter of the receiving groove 21 of the packing portion 20 can be reduced by shrinking the diameter of the cable C as the packing portion 20 is received in the body portion 10. In order to facilitate the movement and contraction of the packing part 20, the packing part 20 is gradually moved from one area of the front end A to one area of the rear end B as shown in Fig. 2 And the inner circumferential surface of the nut coupling part 11 may be formed in an inclined shape corresponding to the shape of the packing part 20 as described above.

That is, by forming the rear end B of the packing part to have a narrow diameter, the packing part 20 can be easily moved toward the inner circumferential surface of the fastening part 13. In addition, by forming the packing portion 20 to have a narrower and wider diameter, shrinkage can be made more freely than a packing portion formed with the same diameter, so that the cable having various diameters can be received.

In addition, the packing portion 20 may be formed in a shape in which the upper edge 22 of the packing portion 20 is inclined. The upper end of the packing section 20 may not touch the nut section 40 so that the packing section 20 can rotate the nut section 40 even when the nut section 40 rotates for threading It may not interfere. At the same time, the side surface of the packing portion 20 can be prevented from being damaged by the rotation of the nut portion 40.

The outer surface of the packing 20 and the washer 30 may be spaced apart from the inner surface of the nut 40 so that the inner surface of the nut 40 is sealed by the packing 20 and the washer 30 without any contact with the outer circumferential surface. The nut portion 40 is engaged with the body portion 10 to press the packing portion 20 and the washer portion 30. At this time, the packing portion 20 and the washer portion 30 are prevented from rotating together with the nut portion 40, and the packing portion 20 and the washer portion 30 are moved only in the vertical direction. This is because when the packing portion 20 rotates together with the nut portion 40, the cable C closely attached to the packing portion 20 rotates together with the cable portion C, And the like may be damaged.

A step 31 may be formed at an upper end of the washer portion 30 and a fastening groove 42 corresponding to the shape of the step 31 of the washer portion 30 may be formed in the nut portion 40 have. At this time, the diameter of the fastening groove 42 may be smaller than the diameter of the female thread 41. It is possible to prevent a part of the packing part 20 from protruding to the outside of the nut part 20 even if the packing part 20 is contracted through such a washer part 30, (20) can be stably pressed. For example, the portion having the largest diameter on the outer circumferential surface of the washer portion 30 may have the same diameter as the portion having the largest diameter on the outer circumferential surface of the packing portion 20.

Fig. 3 shows a fastened state of the cable gland according to an embodiment of the present invention.

Referring to FIG. 3, a cable gland 100 according to an embodiment of the present invention can simplify components. By inserting the packing portion 20 and the washer portion 30 between the body portion 10 and the nut portion 40 and screwing the nut portion 40 to the body portion 10, A sealed waterproof structure can be easily formed. In particular, the cable gland 100 can accommodate cables of various diameters in close contact with each other, and it is possible to solve the inconvenience of the operator having to work the cable by inserting the cable into the packing portion (20 in Fig. In addition, the cable gland 100 can accommodate various pipelines such as pipes as well as cables according to the embodiment.
