Foldable Rail Support for OJC Fixed Rack {Foldable Rail Support for OJC fixed Rack}

The present invention relates to a support for fixing an optical cable connected to a connector of a rack loaded with a plurality of slots, and more particularly, the width between a first support coupled to one side of a slot and a second support coupled to the other side of the slot is adjusted. It is excellent in installation versatility, and it relates to a foldable rail support for fixing an OJC rack that can prevent optical loss and stably maintain an optical communication network by binding the optical cable to the first support and the second support so that the optical cable is formed with a minimum radius of curvature or more.

In general, a communication method using an optical fiber is a communication method in which voice and data signals are converted into electric signals and then converted into light intensity or optical signals, and the voice and data signals are transmitted using total reflection of laser light through optical fibers.

At this time, an optical jumper cord (OJC: Optical Jumper Cord) is an optical cable in which an optical fiber core using quartz glass is secondarily coated with a plastic material and coated thereon.

An optical jumper cord is made of optical fibers in the form of a cable, and connectors are provided at both ends of the cable for connection between transmission devices.

Compared to telecommunication, the communication method using optical cables has no interference from external electromagnetic waves and is difficult to eavesdrop, and can process a large amount of information at the same time. We are building an FTTH (Fiber To The Home) network that lays optical fibers.

In order to build an FTTH network, the quantity of optical cables is increased, and in particular, an optical distribution box for distribution of optical cables is provided in communication rooms of various large buildings.

An optical cable that transmits data using total reflection of light must be formed with a curvature greater than a certain curvature for smooth signal transmission, and when a curvature smaller than this is formed, an error or communication error occurs, and smooth optical communication cannot be guaranteed.

Racks used as optical communication equipment are provided with connectors to which optical cables are connected, and an adapter of the optical cables is connected to the connector to maintain the connection state. When multiple optical cables are connected to the rack, interference occurs between each optical cable. It can be bent below the minimum curvature radius.

If the optical cables are messily connected, it becomes very difficult for the manager to manage for maintenance of the rack.

If the place where the rack is installed is narrow and multiple optical cables are connected, the optical cables are excessively bent and the minimum bending radius cannot be guaranteed. The losing problem arises.

The unfixed optical cable is sagged downward by its own weight, and the deflection caused by its own weight causes instability in the connection between the adapter and the connector, and the optical cable is aged due to continuous fatigue accumulation, so that stable optical communication is not achieved.

In addition, the slots are provided in various sizes according to the purpose of operation, and are installed horizontally or vertically according to the installation space. Corresponding to the size and arrangement direction of the slot, the line and arrangement direction of the optical cable must be changed in order to be connected to the adapter of the slot, which causes the arrangement of the optical cable to become more messy.

Conventional fixtures for fixing optical cables are fixed in size and individually formed along various sizes and arrangement directions of racks equipped with a plurality of slots, so manufacturing costs increase and it is impossible to install them in other rack equipment. versatility is poor.

In order to keep the optical cable connected to the rack and perform maintenance, the connection line of the optical cable must be neatly arranged so that the connection state can be visually identified. There should be no problem with data communication.

Accordingly, the present applicant has filed an application number 30-2022-0001598 『Optical Fiber Bending Prevention Protector』 in order to form the bending portion of the optical cable with a minimum radius of curvature or more. (Application date: 2022.01.13.)

In order to solve this problem, it is used together with the Applicant's 『Optical Fiber Bending Prevention Protector』 to ensure the minimum radius of curvature of the optical cable, to ensure durability as the fatigue of the optical cable does not accumulate, and to operate depending on the purpose of optical communication equipment The development of a fixture with excellent versatility that can be installed in response to the size and arrangement direction of the rack is on the rise.

It includes; a fixed band 400 that binds the optical cable 20 that is reduced in diameter and accommodated therein.

The optical cable 20 transmits data using total reflection of light, and transmits the optical signal by connecting the optical adapter 21 to the optical connector 13 of the optical communication equipment to process the optical signal. At this time, the rack having a plurality of slots 10 refers to optical communication equipment constituting an optical communication network such as a multiplexer (MUX), a switching hub, and a router.

Since the optical cable 20 needs to form a certain radius of curvature to ensure smooth optical communication, if it is excessively bent and formed below the minimum radius of curvature, optical loss occurs, resulting in failures and errors in the optical communication network.

Therefore, when the optical cable 20 is connected to the slot 10 for stable and smooth optical communication, the vicinity of the optical adapter 21 of the optical cable 20 connected to the optical connector 13 of the slot 10 is not excessively bent. It must be formed with a minimum radius of curvature or more.

Furthermore, since the optical cable 20 is formed with a radius of curvature greater than or equal to the minimum radius of curvature, the total reflection angle of light is secured, thereby preventing optical loss and stably maintaining the optical communication network.

As shown in FIGS. 4 to 7 , the slot 10 is fixed and installed on the fixing frame 12 and may be placed in a horizontally lying or vertically erected position. Grooves for coupling the slot 10 are formed on both sides of the fixing frame 12, and the slot 10 and the fixing frame 12 are coupled with bolts.

The fixing frame 12 is formed with a plurality of grooves vertically to fix the slot 10 at a certain height, or the main support 100 of the present invention may be coupled to it.

A plurality of optical connectors 13 of the optical cable 20 are formed on the front surface of the slot 10 . The optical connector 13 is connected to the optical adapter 21 of the optical cable 20 to communicate optical signals. A plurality of optical cables 20 are also bundled into one from the outside of the slot 10, enter the optical connector 13 of the slot 10, and branch at corresponding points to be connected to each optical connector 13.

A fixing hole 11 for coupling the main support 100 is formed in the slot 10 . The fixing hole 11 is formed on both sides of the slot 10 with the optical connector 13 interposed therebetween. After the fastening hole 111a of the main support 100 is placed in contact with the fixing hole 11, the main support 100 may be installed in the slot 10 by bolting.

The optical cable 20 is connected to the optical connector 13 and is provided with a connector 21 for transmitting an optical signal to the slot 10, in order to be connected to the optical connector 13 at the optical adapter 21 part. Bending is common. The bent portion of the optical adapter 21 must be made at or above the minimum radius of curvature to secure the total reflection angle of light, which is the principle of optical communication, so that smooth communication can be achieved. do.

As shown in FIG. 2, the main support 100 according to the present invention is configured to prevent optical loss by fixing the bent portion of the optical cable 20, and the fixing holes formed on both sides of the slot 10 ( 11) or coupled to a groove formed in the fixing frame 12 for fixing the slot 10. The coupling position of the main support 100 can be set in various ways according to the operator's convenience, but the coupling position of the main support 100 is not limited and a position capable of supporting the optical cable 20 is sufficient.

The main support 100 is composed of a first support 110 and a second support 120, but the first support 110 and the second support 120 have similar structures and shapes, and maintain a mutually coupled state. It forms the main support 100 and is coupled to the slot 10 to form a structure capable of fixing the optical cable 20.

The first support 110 is formed with a first bent surface 111 coupled to the fixing hole 11 of the slot 10 or the groove of the fixing frame 12, and on the first bent surface 111 A fastening hole 111a is formed through which the fastening bolt passes. After contacting the first bent surface 111 in the groove of the fixing hole 11 or the fixing frame 12, it is installed by bolting through a fastening bolt.

The first support 110 is formed with a first protrusion 112 that is bent and protrudes from the first bent surface 111 . The first protrusion 112 is perpendicular to the first curved surface 111 and protrudes forward of the slot 10 . That is, the length of the first protrusion 112 is formed toward the front of the slot 10 .

The distance between the first extension 113 and the front surface of the slot 10 is determined according to the protruding length of the first protrusion 112 . The optical cable 20 is fixed to the first extension 113 and is bent by changing the direction to be connected to the optical connector 13. If the protruding length of the first protrusion 112 is excessively short, the slot 10 ) and the first extension 113 is narrowed, and the optical cable 20 is bent below the minimum radius of curvature, causing problems in optical communication. Therefore, the front surface of the slot 10 and the first extension 113 are sufficiently spaced in order to bend the optical cable 20 more than the minimum radius of curvature.

A first extension 113 bent and protruding from the first protrusion 112 is formed on the first support 110 . The first extension 113 is perpendicular to the first protrusion 112 and also perpendicular to the first bent surface 111 . Referring to FIG. 2 , the first protrusion 112 is bent vertically on the first bending surface and protrudes forward, and the first extension 113 is bent horizontally from the first protrusion 112 and protrudes. do.

The first extension 113 is a part where the optical cable 20 is seated and fixed, and has a length longer than the protruding length of the first protrusion 112 in order to stably support by increasing the contact area with the optical cable 20. is formed

A first guide rail 114 is formed on the first extension 113 in the longitudinal direction of the first extension 113 . The first guide rail 114 has a structure through which a fastener 130, which will be described later, is provided to adjust the width of the main support 100. The first guide rail 114 and the second guide rail 124 to be described later are overlapped and slid so as to come into contact with each other, and when the main support 100 is adjusted to a width corresponding to the installation position, the width is controlled by the fastener 130 to fix

In addition, the first guide rail 114 has a configuration in which a bracket support 200 and a bolt support 300, which will be described later, are inserted and fixed, and the bracket support 200 and the bolt support 300 are the first guide rail ( 114), and may be fixed at an appropriate position for binding the optical cable 20. At this time, the position where the bracket support 200 and the bolt support 300 are fixed is a position where the optical cable 20 can be effectively bound, and can be set in various ways by the operator.

The second support 120 is combined with the first support 110 to form the main support 100 . The second support 120 is formed similarly to the structure and shape of the first support 110 .

The second support 120 is formed with a second bent surface 121 in which a fastening hole 111a is formed so that it can be coupled to the slot 10 or the fixed frame 12, and the second bent surface is a fixing hole ( 11) or fixed to the fixing frame 12, a second protrusion 122 is formed perpendicular to the second bent surface 121 and protrudes forward of the slot 10. Since the second bent surface 121 and the second protrusion 122 have the same shape and function as the first bent surface 111 and the first protrusion 112 of the first support 110, a detailed description thereof will be omitted. .

The second support 120 is formed with a second extension 123 that protrudes by being bent perpendicular to the second protrusion 122 . The second extension 123 has the same shape as the first extension 113 of the first support 110, but protrudes in opposite directions. That is, when the first extension unit 113 protrudes toward the right side, the second extension unit 123 protrudes toward the left side.

A second guide rail 124 having the same shape as the first guide rail 114 is formed on the second extension 123 .

The first support 110 and the second support 120 become the main support 100 and form a structure for binding the optical cable 20 .

The first extension 113 of the first support 110 and the second extension 123 of the second support 120 are overlapped and coupled to each other. The first guide rail 114 and the second guide rail 124 are overlapped, and the fastener 130 passes through the first and second guide rails 114 and 124 and is fixed through a bolt connection.

The first extension 113 and the second extension 123 slide in the longitudinal direction, and the main support ( 100) to adjust the width. When the distance between the first and second curved surfaces 111 and 121 is adjusted, the width between the first and second protrusions 112 and 122 is also changed.

The more the overlapping portions of the first and second extensions 113 and 123 are, the shorter the width of the main support 100 is. ) When coupled through, the width of the main support 100 is formed to the maximum.

The fastener 130 is formed in a screw shape, and is coupled with a nut 500 to fix the first extension 113 and the second extension 123. The first and second extensions 113 and 123 in a state in which the nut 500 is loosely loosened without completely disassembling the nut 500 in a state in which the fastener 130 passes through the first and second guide rails 114 and 124 The width of the main support 100 is adjusted by sliding, and when it is formed to an appropriate width, the nut 500 is tightened again so that the first and second extensions 113 and 123 can be tightly coupled to each other. The fastener 130 fixes a gap between the first and second curved surfaces 111 and 121 or between the first and second protrusions 112 and 122 . The width of the main support 100 can be conveniently adjusted even when the nut 500 is loosened slightly.

Therefore, the width of the main support 100 can be varied according to the length of the slot 10 to which the main support 100 is coupled, so that it can be installed in various lengths and sizes of the slot 10 .

In addition, even if the main support 100 is installed in the fixing frame 12 instead of the fixing hole 11 of the slot 10, the optical cable 20 can be effectively bound by adjusting the width of the main support 100. By combining with a variable width, it is possible to install the main support 100 regardless of the size of the fixed frame 12, so it can be applied to various installation environments and has excellent versatility.

The main support 100 is bound to the optical cable 20 that proceeds along the longitudinal direction of the first and second extensions 113 and 123 . The optical cable 20 proceeds along the first and second extension units 113 and 123, and the optical adapter 21 is bent to be connected to the optical connector 13 of the slot 10. At this time. When the main support 100 is disposed at the same height as the optical connector 13 of the slot 10, it can be bent toward the optical connector 13 provided in the front of the slot 10 without being bent vertically. there is.

However, when the main support 100 is installed at a position different from the height of the slot 10 to be connected, the optical cable 20 is bent upward or downward while progressing in the first and second extension units 113 and 123.

The bracket support 200 is formed with a through slit 230 penetrating the binding surface 220 . The through slit 230 becomes a groove into which a fixing band 400 to be described later is inserted.

When the main support 100 is installed in the horizontal direction, the bracket support 200 protrudes from the main support 100 in the vertical direction. The optical cable 20 is fixed to the binding surface 220 of the bracket support 200 by the fixing band 400 while being bent in the vertical direction. Therefore, fatigue is not accumulated by preventing sagging of the optical cable 20 due to its own load, and the optical communication network can be stably maintained by maintaining the connection state of the optical connector 13 and the optical adapter 21. .

Referring to FIG. 6 , the direction of the binding surface 220 of the bracket support 200 can be arbitrarily set by an operator. When the optical cable is fixed with a narrow gap between the optical cable 20 and the optical connector 13, the first guide rail 114 Or coupled to the second guide rail (124).

Alternatively, when it is necessary to sufficiently space the optical cable 20 and the optical connector 13, the binding surface 220 is placed in front of the sliding hole 210 and then fixed so that the optical cable 20 is connected to the optical connector ( 13) and can be formed with more than the minimum radius of curvature.

In addition, by arranging and fixing the binding surface 220 facing left and right instead of front and rear on the sliding hole 210, the optical cable 20 can be fixed at an intermediate position compared to the front and rear positions. . Through this, even if the number of optical cables 20 connected to the plurality of slots 10 is large in a narrow rack, while maintaining an appropriate radius of curvature, the front, rear, or same position of the first guide rail 114 or the second guide rail 124 and Since it can be coupled, the optical cable 20 can be stably fixed with a margin.

In addition, as shown in Figure 3 (b), the present invention is provided with a pillar-shaped bolt support (300). A coupling part 310 is formed on one side of the bolt support 300 . The coupling part 310 is formed in a screw shape and is composed of a female screw or a male screw.

After placing the coupling part 310 vertically at an arbitrary position of the first guide rail 114 or the second guide rail 124, it is fixed by bolting.

The optical cable 20 is fixed to the outer circumferential surface of the bolt support 300 by a fixing band 400.

Two bolt supports 300 may be provided.
