Description

(Non-cutting type of Optical Fiber Cable Nets)

The present invention relates to an optical fiber cable network having no end cut at one end and more particularly to a fiber optic cable network having a flexible fiber optic cable having flexibility, And an unshielded optical fiber cable network formed by one optical fiber cable.

Today, security fences are being installed to protect certain facilities or specific areas from external intrusions. It is important that security fences detect and prevent external intruders from penetrating security facilities or security areas.

Conventional conventional security fences have been focused on preventing the intruder from easily cutting or bending the wire mesh by forming a solid wire mesh in order to prevent an intruder from easily penetrating the interface of the security fence. For this purpose, a quadrilateral diagonal net or a hexagonal close-in net was used to form a wire net using a strong wire. However, even though the wire net has a strong characteristic by the wire, the wire can easily be rusted and the outer penetrant can be easily cut using a cutter, and the site of the cut can not be easily found.

In consideration of these physical limitations, the concept of a security fence using a fiber optic cable has emerged. The security fence using the optical fiber cable forms an optical fiber cable network by forming a predetermined net using the optical fiber cable, and utilizes the optical fiber cable network as an interface of the security fence. The use of fiber optic cable networks may cause information to be blocked on the fiber optic cable embedded in the optical fiber cable or cause severe distortion when the penetrator cuts the optical fiber cable network or bends the optical fiber cable beyond a certain degree So that the security fence can be instantly detected when it is cut or bent.

In the conventional optical fiber cable network, when a cable network of hexagonal or quadrangular shape is manufactured by using two optical fiber cables, the two optical fiber cables cross each other to form a predetermined twisted structure. Before and after making the kink structure at the starting point and the final finishing point, the cut parts exist.

Since the security fence uses an optical fiber embedded in the optical fiber cable, the smaller the cut portion of the optical fence is, the better it is. In an optical fiber cable net having a single sheet shape, It should be said that this is an undesirable phenomenon.

Korean Patent No. 614824 "Detection system using optical cable" (2006. 08. 16.); Korea Utility Model Registration No. 443989 "Network Structure of Optical Cable for Intrusion Alarm System" (Mar. 24, 2009); Korea Patent No. 1189013 "Optical Fiber Network and Method of Manufacturing" (2012. 09. 28.); Korea Patent No. 1264029 "Optical Fiber Network and Method for Manufacturing" (Feb. Korean Registered Patent No. 1396425 "Automatic Production Device for Fiber Optic Cable Network" (May 5, 2014).

The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a fiber optic cable network having a hexagonal net through which a plurality of first cables and a plurality of second cables are used to form a twisted structure And an object of the present invention is to provide an optical fiber cable network without an end of the initial starting point of the optical fiber cable network, which is completed as one cable.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a cable connector in which a plurality of first cables and a plurality of second cables form a twisted structure, And a first plurality of first cables and a plurality of second cables are twisted together to form a twisted structure. In the optical fiber cable network which repeatedly performs this process, The polygonal cable net at the initial starting point of the fiber optic cable network is formed by a single cable and is formed by a first cable, a connecting cable and a second cable, and thereafter, the first cable and the second cable Type optical fiber cable in which a hexagonal cable network is continuously and repeatedly formed in a conventional manner It provides.

In manufacturing the optical fiber cable network, since the optical fiber cable network is manufactured in a state where one end of the optical fiber cable network is connected by using one optical fiber cable without cutting it, the cut optical fiber cable must be separately welded There is no hassle.

In addition, since the present invention does not need to perform a separate welding operation, there is also an advantage that information distortion due to the cut portion can be greatly reduced.

In addition, since the optical fiber cable network according to the present invention has a structure in which one end is connected without being cut off, when it is used as a security fence, the installation work time can be drastically reduced, There is also.

It is to be understood, however, that the drawings are for the purpose of describing the technical idea of the present invention in more detail and that the technical idea of the present invention is not limited thereto and that various modifications are possible. In the specification of the present invention, the same reference numerals are used for the same parts, and parts that can be easily created by those having ordinary skill in the art are omitted in the description of the present invention. .

The present invention relates to an optical fiber cable network in which a plurality of first cables (C1) and a plurality of second cables (C2) are twisted to each other, wherein an end of the first starting point of the optical fiber cable network Type optical fiber cable network 100 that is completed in a shape that is connected as a cable of an optical fiber cable.

FIG. 1 is a schematic conceptual view showing a non-branching cable network 100 according to the present invention as a whole,

FIG. 2 is an enlarged view of an essential part of the non-single-mode cable network 100 according to the present invention,

3 is an enlarged view of the "A" portion and the "B" portion of FIG.

The non-fiber optic cable network 100 according to the present invention includes a plurality of pentagonal net eyes 110 at an initial starting point of the optical fiber cable network.

The non-fiber optic cable network 100 according to the present invention uses a plurality of first cables C1 to form the pentagonal net 110, and the cables are connected without being cut And a plurality of second cables C2 extending in the direction opposite to the traveling direction of the plurality of first cables C1 by changing the initial traveling direction of the connecting cables C3, .

The plurality of first cables (C1) and the plurality of second cables (C2) are then twisted together to form a twist structure (C tw ), and then each of the first cables C1 and the respective second cables C2 are widened to form a twist structure C tw of the next step. This forms the first polygonal cable netting, which, as seen in the figure, forms a pentagonal netting 110.

The pentagonal net 110 is formed of a connection cable C3 and a twisted structure C tw on both sides and a plurality of first cables C1 and a plurality of second cables C2 extending to both sides . At this time, it can be seen that the connecting cable C3 forming the left side of the pentagonal net 110 is directly connected to the first cable C1 and the second cable C2 and is not cut at all .

In forming the pentagonal net 110, the twisted structure C tw is formed by twisting the first cable C1 and the second cable C2 to each other, Or may be made in a conventional manner. The conventional method means that the optical fiber cable is manufactured by using the automatic production apparatus of optical fiber cable network, which is developed by the inventors of the present invention and obtained patent rights. Since this method is already known, a detailed description will be omitted.

In forming the twisted structure C tw , the first cable C1 and the second cable C2 may be formed by rotating about three to nine rotations, or alternatively about three to five rotations may be formed .

Fig. 3A shows the case of three revolutions, whereas Fig. 3B shows the case of five revolutions.

As a result, the non-fiber optic cable network 100 according to the present invention forms a plurality of pentagonal net eyes 110 at the initial starting point in this manner, As shown in FIG.

The non-fiber-optic cable network 100 according to the present invention forms a hexagonal net 120 in a state connected to the pentagonal net 110.

The hexagonal net 120 is formed such that each of the first cables C1 and each second cable C2 that are separated from the pentagonal net 110 formed before is brought into contact with each other and twisted After the structure C tw is formed and the twisted structure is formed again, the respective first cables (C1) and the respective second cables (C2) are divided on both sides to form a first contact point And again forms a new twist structure C tw at that point. Through this process, new pentagons 120 connected to the pentagonal net 110 are generated.

The first cable C1 and the second cable C2 may be formed by rotating about three to nine revolutions in the twist structure C tw for generating the hexagonal net 120. Alternatively, It may be formed by rotating about 5 to 5 rotations. 3A shows the case of three rotations while FIG. 3B shows the case of five rotations.

The non-fiber optic cable network 100 according to the present invention continuously and repeatedly forms the same hexagonal net 120 in a state connected to the hexagonal net 120.

The hexagonal net 120 is formed such that each of the first cables C1 and each second cable C2 separated from the hexagonal net 120 generated in the previous stage meet each other and are twisted After the structure C tw is formed and the twisted structure is formed again, the respective first cables (C1) and the respective second cables (C2) are divided on both sides to form a first contact point And again forms a new twist structure C tw at that point. By forming the twist structure C tw in such a manner continuously and repeatedly, all subsequent hexagonal net eyes 120 are formed.

Also, the method of forming the hexagonal net 120 can be carried out by a conventional method. More specifically, the invention is disclosed in Patent Registration No. 1396425 "Automatic Production Device of Optical Fiber Cable Network" developed by the inventors of the present invention And therefore, a detailed description thereof will be omitted.

Since the present invention can provide an optical fiber cable network (100) formed by an optical fiber cable that is connected to one end without being cut at one end, when a security fence or a security fence is manufactured later, There is an advantage that the work of bonding and bonding the optical fiber can be greatly reduced.

Although the non-fiber optic cable network 100 according to the present invention has been described in detail above, it should be understood that the present invention is not limited thereto, The range is determined and limited.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
