Description

Technical Field

[0002] Currently, optical fibers are led out from the left and right sides of the optical splitter device inside the optical splitter. According to the optical splitting requirements of different products, the main optical splitting path will be equally or unequally divided into multiple optical fibers for transmission, and the number of optical fiber flange connectors corresponds to the number of transmission optical fibers. Usually, in order to save the internal space of the product, the optical fiber flange connectors will be arranged closely together, which brings great difficulties to the assembly of the optical fiber flange connectors and the plugging and unplugging of multiple optical fibers.

[0003] For example, the fiber optic flange connector is connected to the housing of the splitter through a flange fixing bracket. The flange fixing bracket is designed with an installation groove for confining multiple fiber optic flange connectors together. However, the fiber optic flange connector includes an ordinary flange or a flip-up flange. The current bracket is hardly compatible with the ordinary flange or the flip-up flange, which causes inconvenience to the actual fiber splitting work.

During the actual installation process, the bracket needs to be replaced according to the different types or quantities of fiber optic flange connectors, and a new splitter often needs to be redesigned, which increases costs.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] Fiber optic flange is a device specially used for fiber optic connection, which is used to connect the fiber optic connector to the fiber tail and provide stable mechanical support and protection. It is usually made of metal or plastic materials, and has the functions of fixing the fiber optic connection, protecting the fiber optic end and providing connection stability. The fiber optic flange adopts a threaded connection or a fastening structure, which can firmly fix the fiber optic connector on the flange and ensure the reliability and stability of the connection. In addition, the fiber optic flange can also provide dustproof, waterproof and shockproof functions to protect the fiber optic connection from the influence of the external environment.

[0035] Among them, the difference between the flip-up flange and the ordinary flange is that its port has a flip-up, which causes the insertion end size of the optical fiber flange to be larger. Because of this, the mounting slot of the bracket suitable for the ordinary flange cannot match the flip-up flange, and the mounting slot size of the bracket needs to be changed, so it is incompatible.

[0036] Furthermore, the flange fixing bracket in the splitter and the shell of the splitter are an integrated injection-molded structure or connected by bonding. During the actual installation process, the flange fixing bracket needs to be replaced according to the different types or quantities of optical fiber flange connectors, and a new splitter often needs to be redesigned, which increases costs.

[0037] This application is a fiber storage box product structure design, suitable for FTTR networking applications, specifically a splitter.

[0038] The following is an explanation of the above questions one by one:

[0039] In a first aspect, an embodiment of the present application provides a flange fixing bracket to solve the problem in the related art that the bracket for fixing the optical fiber flange connector is difficult to be compatible with ordinary flanges or flip flanges.

[0040] See also Figure 4-Figure 7 , a flange fixing bracket, comprising:

[0041] The bottom shell contact plate 1 has vertical plates 2 parallel to its wide sides at both ends in the length direction;

[0042] The limiting rib 3 is located on the top of the two vertical plates 2 and is connected to one side of the vertical plate 2 in the wide side direction to enclose a flange slot 15; the limiting rib 3, the vertical plate 2 and one side of the bottom shell contact plate 1 in the wide side direction are coplanar to form a first abutting portion 4; the other side of the limiting rib 3 in the wide side direction is a second abutting portion 5.

[0043] When the common flange is connected through the above settings, the elastic sheet and flange plate of the common flange are marked as f and e respectively. Figure 6 As shown in ), the common flange is inserted in the normal insertion direction. When the limiting rib 3 is located between the flange plate and the elastic sheet of the common flange, and the elastic sheet of the common flange abuts against the second abutting portion 5, and the flange plate abuts against the first abutting portion 4, the connection is completed. Figure 6 The insertion direction a of the common flange is shown in .

[0044] When the flap flange is connected, the elastic sheet and flange plate of the flap flange are marked with h and g respectively. Figure 7 As shown in ). The end of the flap flange away from the flap first passes between the two vertical plates 2, and then passes through the flange slot 15. When the limiting rib 3 is located between the flange plate and the elastic sheet of the flap flange, and the elastic sheet of the flap flange abuts against the first abutting portion 4, and the flange abuts against the second abutting portion 5, the connection is completed. Figure 7 The insertion direction of the common flange is shown in b.

[0045] The above limiting ribs 3 are arranged at positions to ensure that the flap flange can be easily placed between the two vertical plates 2. If the limiting ribs 3 completely cover the tops of the two vertical plates 2, the flap flange cannot be placed and the purpose of compatibility cannot be achieved.

[0046] The above shows that the purpose of compatibility between ordinary flange and flip flange can be achieved without replacing the bracket. Figure 6 Mark c in the cover flange is Figure 7 Mark d in .

[0047] In some preferred embodiments, when the flap flange is connected, only one of the elastic sheets is held in position, that is, held against the limiting rib 3, and the other elastic sheet is not held in position. To enhance the limiting effect, the following settings are provided:

[0048] The top of the bottom shell contact plate 1 is provided with a sink 6 located between the two vertical plates 2; the width of the sink 6 is smaller than the width of the bottom shell contact plate 1;

[0049] In the width direction, the side wall surface of the recessed groove 6 close to the limiting rib 3 and the second abutting portion 5 are located on the same vertical plane. In this case, the side wall surface can also be used as the second abutting portion 5 .

[0050] The above-mentioned recessed groove 6 provides an escape space for the flange, and has a second abutting portion 5, thereby achieving the technical effect of increasing the abutting area and maintaining the upper and lower abutments stable.

[0051] Furthermore, the depth of the recessed groove 6 is equal to the distance between the top surface and the bottom surface of the limiting rib 3, so that the bottom wall of the recessed groove 6 can also support the outer ring of the flange to avoid upward and downward deviation.

[0052] In some preferred embodiments, there is no limit to the number of flange slots 15 of the flange fixing bracket introduced above, which needs to be determined according to the number of flanges that need to be connected. When there are multiple flanges, the above structure needs to be slightly adjusted.

[0053] A plurality of spaced-apart partitions 7 are disposed on the bottom shell contact plate 1 and between the two vertical plates 2 to divide the flange slot 15 into a plurality of plug-in slots; the top of the partition 7 is connected to the bottom surface of the limiting rib 3 .

[0054] This allows for the installation of one IN optical fiber and no less than one OUT optical fiber (the figure takes five OUT optical fibers as an example).

[0055] Furthermore, in order to facilitate the removal of the flange on the basis of compatibility, the following settings are also made:

[0056] The bottom wall of the sink 6 is provided with disassembly windows 8 equal to the number of the plug-in slots. The disassembly windows 8 are used to be arranged just below the elastic sheet of the flange. When disassembling, a tool is used to pass through the disassembly windows 8 and press the elastic sheet.

[0057] Further, in order to facilitate the overall positioning of the flange fixing bracket and the connection of the optical splitter housing 12, an opening groove 9 is provided on the bottom surface of the bottom shell contact plate 1, and the number of the opening grooves 9 is two. Figure 5 , an opening slot 9 is connected to a disassembly window 8, and the disassembly window 8 is a part of the opening slot 9. This arrangement can reduce the area of ​​the slot on the bottom shell contact plate 1; a buckle 10 is provided on a side wall of the opening slot 9 away from the limiting rib 3 in the wide side direction, and the extension direction of the buckle 10 is parallel to the wide side direction. In this way, the direction in which the flange fixing bracket is pushed in for installation is parallel to the direction in which the flange is inserted, and it is automatically clamped after being pushed in for a certain distance; such a structure integrates the disassembly connection structure of the flange fixing bracket and the spectrometer housing 12, and the disassembly connection structure of the flange fixing bracket and the flange, which facilitates the installation of the flange fixing bracket while simplifying the structure.

[0058] Of course, this embodiment does not exclude the possibility that the opening groove 9 and the disassembly window 8 can be separated and arranged separately, that is, the disassembly window 8 on the bottom surface of the bottom shell contact plate 1 is not a part of the opening groove 9, and the two are spaced apart. This form also has the function of disassembling and connecting the flange fixing bracket with the splitter housing 12, and the function of disassembling and connecting the flange fixing bracket with the flange, but does not have the function of simplifying the structure while facilitating the installation of the flange fixing bracket.

[0059] Furthermore, in order to facilitate accurate installation of the flange fixing bracket and push it into the receiving groove, the vertical plate 2 is provided with a guide rail 11 on the outer wall surface in the length direction of the bottom shell contact plate 1; the guide rail 11 is parallel to the wide side direction.

[0060] refer to Figure 1-Figure 3 In a second aspect, a spectrometer is provided, comprising:

[0061] The flange fixing bracket described above;

[0062] The optical splitter housing 12 is provided with a receiving groove; the flange fixing bracket is installed in the receiving groove. The size of the flange slot 15 in the flange fixing bracket is determined by the size of the flange to be connected, and the number of the flange slots 15 in the flange fixing bracket can be greater than the number of flanges to be connected.

[0063] The above shows that according to the number of different optical fiber connections and the size specifications of the flanges corresponding to the optical fibers, the corresponding flange fixing bracket can be selected to facilitate wiring operations. The bottom wall of the receiving groove is provided with a locking groove 13 engaged with the buckle 10; the side wall of the receiving groove is provided with a slide groove 14 matched with the guide rail 11. The use of the slide groove 14 and the guide rail 11 facilitates the installation and guidance of the flange fixing bracket, and the buckle 10 and the locking groove 13 facilitate the disassembly and replacement of the flange fixing bracket, as well as the self-locking engagement.

[0064] This solves the problem that the bracket and the splitter housing are formed by integrated injection molding or connected by bonding. During the actual installation process, the bracket needs to be replaced according to the different types or quantities of fiber optic flange connectors, which often requires redesigning a new splitter, resulting in increased costs.

[0065] It should be understood that the above flange fixing bracket can be used in various communication devices that require optical fiber connection, including but not limited to splitters.

[0066] Principles of this application:

[0067] When the common flange is connected, it is inserted in the normal insertion direction. When the limiting rib 3 is located between the flange plate and the elastic sheet of the common flange, and the elastic sheet of the common flange abuts against the second abutting portion 5, and the flange plate abuts against the first abutting portion 4, the connection is completed. Figure 6 The insertion direction a of the common flange is shown in .

[0068] When the flap flange is connected, the end of the flap flange away from the flap first passes between the two vertical plates 2, and then passes through the flange slot 15. When the limiting rib 3 is located between the flange plate and the elastic sheet of the flap flange, and the elastic sheet of the flap flange abuts against the first abutting portion 4, and the flange abuts against the second abutting portion 5, the connection is completed. Figure 7 The insertion direction of the common flange is shown in b.
