The present invention relates to a guide rail installed for disposing a printed circuit board in a self-contained communication device. In particular, the guide rail is a separate type separated by a coupler connected to both sides fixed to a frame and a connection bar connecting them. As it is manufactured to have no directionality, it is easy to assemble and manage parts such as the length of guide rail can be arbitrarily adjusted according to the size of the shelf. Separating guide of communication device to improve the function and reliability of the product by improving the cooling effect by minimizing the contact resistance with the air blown from the blower to cool the heat and minimizing the noise caused by the air resistance. It is to provide a rail.

In general, a communication device includes a plurality of units in which electronic components are arranged to form a single shelf, and a plurality of units together form a single communication system.

As shown in FIG. 1, four frames 11a, 11b, 11c, and 11d arranged horizontally above and below front and rear parts forming a skeleton of the shelf 10, as shown in FIG. And a self-side plate 12 provided on both left and right sides to fix the four frames 11a, 11b, 11c, and 11d, and a backplane 13 provided on the rear side.

Inside the shelf 10, a plurality of units 20 in which electronic circuits are disposed are detachably inserted and arranged, and the unit 20 is largely a printed circuit board 21, a unit front plate 30, and a backplane ( 13 and the upper and lower parts of the unit connector 22 and the unit front plate 30 corresponding to the backplane connector 14 installed thereon, and the long and detachable ejector 23 for attaching and detaching the unit 20. Consists of parts.

In order to arrange the unit 20 on the shelf 10, a guide groove 111 is formed in the upper and lower frames 11a, 11b, 11c, and 11d installed up and down, and guides and fixes the printed circuit board 21. The rail 35 is placed in front and rear, and both ends thereof are assembled to the installation groove 111, and a plurality of horizontally spaced intervals are installed. In addition, the substrate guide groove 351 through which the printed circuit board 21 is guided is formed in front and rear facing the upper and lower guide rails 35 so that the printed circuit board 21 is fitted into each guide rail 35 so that the self guide 10 (See FIG. 1) and as shown in FIG. 1, the printed circuit board 21 has a connector 22 formed at a rear side thereof to guide the upper and lower guide rails 35. And inserted into the interior of the shelf 10 and correspondingly connected to the backplane connector 14 provided on the backplane 13. At this time, the connector 22 is used for the ejector 23, which is installed on the front plate 30 of the unit 20, is detachable.

In the self-structure having such a structure, the guide rail 35 installed so that the printed circuit board 21 is disposed has a plurality of positioning posts at the front and rear ends thereof as shown in FIGS. 2 and 3. Posts 113 are formed, respectively, and are inserted into the positioning holes 352 formed at regular intervals in the installation grooves 111 of the frames 11a, 11b, 11c, and 11d, and the front and rear portions of the respective positioning posts 113 are formed. Hooks 114 are formed respectively to support the guide rails 35 to the frames 11a, 11b, 11c, and 11d. As a result, there are four hooks 114 at one end of the guide rails 35. The guide rails 35 are fixed by being inserted into the installation grooves 111 of the frames 11a, 11b, 11c, and 11d and being caught by the locking jaw 115 of the installation grooves 111.

However, since the conventional guide rails 35 are formed of plastic injection molding, the guide rails 35 having different lengths and sizes according to the sizes of the shelves 10 are manufactured in order to be applied to the shelves 10 having different sizes. In addition, there is a disadvantage in that it is difficult to manage because it must be separately managed according to the size also when managing this, especially ribs 356 formed on the bottom of the guide rail 35 as shown in FIG. And because the substrate guide groove 351 formed on the upper surface is formed asymmetrically biased to one side, it has a certain direction according to the assembly, so it must be checked and assembled when assembling, so there is a closed end to the difficulty of assembly.

In addition, as the system is miniaturized, high heat is generated due to electrical operation inside the system due to the increase in density, and a cooling device such as a blower is installed inside the self 10 to prevent this. By the way, the conventional guide rail 35 is made of a synthetic resin of weak strength, so to increase the width and to have a plurality of ribs (353) on the bottom at the same time to reinforce it, such a structure takes a lot of material and manufacturing costs In addition, since it interferes with the circulation of the wind and air flow to cool the internal heat of the self (10) acts as a factor to reduce the cooling effect, and also the air passing through the guide rail 35 ribs formed on the bottom ( 353) caused the vortex to cause severe noise (see Figure 4).

The present invention is devised to solve the conventional closed end as described above, the guide rail is to be used to assemble the coupling portion on both sides of the guide bar when using the coupling portion formed on both sides to use, so that the coupling portion and the guide bar does not have directionality By making the joining part as a single part, the manufacturing cost is reduced, the parts can be easily managed, and the assembly is easy, and the length of the guide bar is made long so that even if the size of the self is different The purpose of the present invention is to provide a detachable guide rail of a communication device that can be used by uniformly applying to all sizes of self by cutting the guide bar to assemble the coupling part at both sides to arbitrarily adjust the length of the guide bar.

Another object of the present invention is to improve the guide bar cross-sectional structure of the guide rail to increase the cooling effect by smoothly maintaining the flow of air blown by the blower to cool the high heat generated by the electrical operation of the densified self The purpose is to make it possible.

The present invention for achieving the above object is a guide bar formed with a substrate guide groove in the longitudinal direction on one side and the hollow inside, coupled to both side ends of the guide bar and continuous with the substrate sleeve groove of the guide bar on one side It has a substrate guide groove, the opposite side has a positioning post protruding side by side and a hook protruding before and after each of the positioning posts, one side end is a guide bar protruding in the cross-sectional structure of the hollow hollow Characterized in that consisting of a coupler including an insertion hole to be inserted into the hollow portion of the.

In addition, the guide bar of the present invention has a material of an aluminum tube, the cross-sectional shape has a structure of a square tube or characterized in that the opposite surface of the substrate guide groove protrudes.

A plurality of crystal holes 352 are formed, and the locking jaw 115 is formed at the front and rear inner surfaces of the installation groove 111.

In addition, reference numeral 50 is a guide rail 50, as shown in Figures 5 and 6 assembling the guide bar 51 of the tubular structure with a hollow inside, and the guide bar 51 and both side ends It consists of a coupler 52 which is, the guide bar 51 has a substrate guide groove (512a) in which the printed circuit board 31 (see FIG. 1) of the self-aligned 10 is inserted into one side in the longitudinal direction. The coupler 52 coupled to both sides is formed, the substrate guide groove 512a and the continuous substrate guide groove 512b of the guide bar 51 are formed on one side thereof, and the opposite side is positioned The crystal post 113 is laterally protruded side by side to fit into the positioning hole 352 of the installation groove 11, the hook 114 is protruded to the front and rear portions of the respective positioning post 113 After being inserted into the mounting groove 111 of the frames 11a, 11b, 11c, and 11d, the guide bar 51 is fixed to the frames 11a, 11b, 11c, and 11d by the front and rear locking jaw 115. On one side end of the coupling port 52 is inserted into the hollow 511 of the both ends of the guide bar 51 protruding in the same structure as the cross-sectional shape of the hollow portion 511 of the guide bar 51 In particular, one side of the insertion hole 521 to be inserted is formed with a guide bar 51 and a lobe 522 to increase the coupling force.

In addition, the guide bar 51 is made of a metal such as aluminum, the cross-sectional view has a rectangular tube as shown in Figure 7 or as shown in Figure 8 the lower portion of the rectangular tube protrudes in the V shape Has a cross section of the structure.

Looking at the operation and effects of the guide rail having the above structure as follows.

First, the coupler 52 is assembled to the hollow portions 511 of both ends of the guide bar 51, but the substrate guide groove 512a of the guide bar 51 and the substrate guide groove of the coupler 52 512b) are continuously matched, and then the insertion hole 521 is inserted into the hollow portions 511 at both ends of the guide bar 51 by interference fit. At this time, the lobe 522 of the insertion hole 521 is in close contact with the inside of the guide bar 51 to fix each other tightly to increase the bonding force (see FIGS. 5 and 6).

When the guide rail 50 is formed as described above, the positioning posts 113 formed on the coupling holes 52 on both sides of the guide rail 50 are laterally disposed on the frames 11a, 11b, 11c, and 11d of the shelf 10. Inserting the hook 114 formed before and after the positioning post 113 into the installation groove 111 and inserting into the positioning hole 352 of the formed installation groove 111 at the front and rear locking jaw of the installation groove 111 ( 115) to secure it. In such a manner, a plurality of horizontal intervals are installed on the frames 11a, 11b, 11c, and 11d of the shelf 10, and then the printed circuit board 21 constituting the unit is provided with the substrate guide groove of the guide rail 50. Inserted and removed at (512a, 512b). When the guide rails 50 are assembled and used as described above, the guide bars 51 and the coupling holes 52 do not have directivity, so in the case of the guide bars 51, only the long guide bars 51 are manufactured. Since the coupler 52 only needs to produce the coupler 52 having the same structure without covering the left and right, it is easy to manufacture a mold according to the injection molding of the coupler 52, and the guide bar 51 is pulled out by extrusion. It is easy to manufacture because it can be produced, and significant manufacturing cost is reduced, and when assembling, the guide bar 51 may be cut according to the size of various shelves 10 to assemble the coupler 52 at both ends. It is also easy and has significant advantages in parts management.

In addition, since the guide bar 51 is made of a metal such as aluminum, the guide bar 51 has a high strength and high strength even at a small thickness, and thus does not require a rib (see FIG. 2) like a conventional guide rail. Therefore, the cross-sectional shape also has a simple square tube cross-section as shown in FIG. 7 so that the resistance with the air supplied to the blower not shown in the drawing to cool the internal heat of the shelf 10 can be reduced to a minimum. Since it is possible to increase the cooling effect, the vortex of the air due to the contact with the guide bar 51 is reduced, the noise is also reduced.

In particular, as shown in FIG. 8, when the opposite surfaces of the substrate guide grooves 512a and 512b of the guide bar 51 have a pentagonal tube projecting in a V-shape, the air flows more smoothly. By minimizing the resistance to the flow and the vortex, the cooling effect of the internal circuit is increased to increase the reliability of the system as the stability, system quietness and durability of the system are improved.
