Description

[0001] CABLE FIXING STRUCTURE HAVING A SHIP EARTH FUNCTION [0002]

The present invention relates to a cable fixing structure having a hull grounding function, and more particularly to a cable fixing structure having a hull grounding function.

Generally, the hull is equipped with cables of various sizes, such as electrical cables.

Conventionally, a cable fixture, through which cables are inserted and fixed, is installed on the hull so that such cables can be installed along the inner space of the hull.

Particularly, MCT and RISE are applied to the portion where the cable penetrates as described above.

That is, the MCT and RISE can advantageously maintain the original shape easily in a high temperature environment when a fire is generated in a room, can block the harmful gas caused by the fire, Because of its advantages, it is mainly used in the cable penetration section.

Especially, Rise is more widely used than MCT to dry mountainside because it is simpler and cheaper than MCT, but it can not perform the function of electromagnetic wave shielding because it has a function that it can not be grounded on the hull.

Therefore, conventionally, the application of the rise is limited in the MC zone and the electromagnetic noise protection section, and an expensive EMC MCT is applied.

Here, the MC cable has a long delivery period due to customization, and when the cable is installed or modified, the time required for disassembling and reinstalling the interlock block increases.

Referring to FIGS. 1 to 3, the cable fixing structure having the hull grounding function of the present invention is provided in an electromagnetic wave blocking region formed in the hull.

The cable fixing structure having the hull grounding function is largely constituted by the penetration portion 100, the cable fixing portion 200, and the cable grounding portion 300.

The penetration part 100 is formed in the hull 10 and is formed as a hole through which a plurality of cables 400 pass.

The size of the penetration part 100 is formed to be proportional to the number of the cables 400 to be penetrated.

The cable fixing part 200 is installed in the penetrating part 100.

The cable fixing part 200 serves to fix the plurality of cables 400.

The cable fixing part 200 will be described in detail.

The cable fixing part 200 is largely composed of a cable coaming part 210 and a sealant 200.

The cable coamer 210 is formed in a hollow shape and is formed of a metal having a function of a weld W.

The cable coamings 210 are arranged to fit into the through holes 100.

The cable coamings 210 are welded (W) to the through holes 100 through a welding process. Both ends of the cable coamer 210 protrude from both sides of the penetration portion 100 of the hull 10.

The plurality of cables 400 pass through the cable coamings 210.

The sealant 220 is a member for airtightness and is installed at both ends of the cable coaming 210.

At this time, the sealant 220 also serves to fix each cable 400 at both ends of the cable coaming 210.

The cable grounding unit 300 according to the present invention is installed in the cable fixing unit 200 and functions to ground each of the cables 400 to the hull 10.

The configuration of the cable grounding unit 300 will be described.

The cable grounding part 300 is installed inside the cable fixing part 200.

The upper and lower ends of the cable grounding unit 300 are connected to upper and lower ends of the cable coaming unit 210 and are physically connected to the shield lines 410 of the plurality of cables 400.

Here, the cable grounding unit 300 according to the present invention includes a grounding body 310 and a grounding hole 320.

The grounding body 310 is formed of a plate-shaped copper wool.

The upper and lower ends of the grounding body 310 are fixedly connected to the upper and lower ends of the cable combing 210.

Accordingly, the grounding body 310 may form a grounding passage in the cable combing 210 and the hull 10 welded thereto.

The plurality of ground holes 320 are connected to the shield wires 410 of the plurality of cables 400 through the through holes.

Here, in each of the plurality of cables 400, a region where a part of the cover is peeled off is formed.
