Description

Technical Field

[0001] The utility model relates to the technical field of splitters, in particular to a combinable optical splitter. Background Art

[0002] The traditional cassette-style optical splitter housing design has significant limitations. Its limited four through-holes and reliance on four screws for mounting are inadequate given the rapid growth of data centers and the increasing density of devices. When multiple cassette-style optical splitters need to be packaged together, the traditional cassette structure necessitates the use of long screws for securing them through the holes. This approach presents numerous challenges.

[0003] First, stacking different numbers of cassette-type optical splitters requires different screw lengths. This necessitates precise selection of screws of the appropriate length during installation; otherwise, effective securing cannot be achieved. For example, stacking three cassette-type optical splitters might require 8-centimeter screws, while stacking five might require 12-centimeter screws. An incorrect selection can lead to installation failure and the need to search for the right screws, wasting considerable time and effort. Secondly, frequently changing screws of varying lengths increases installation complexity and the potential for error. In practice, workers may confuse screw lengths or misjudge the required length, leading to installation errors and compromising the overall packaging process. Furthermore, this installation method introduces significant inconvenience during maintenance and disassembly. If a cassette-type optical splitter fails and requires repair or replacement, the complexity of securing it with the long screws makes disassembly extremely cumbersome, increasing repair time and cost.

[0027] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] This specific embodiment provides a combinable optical splitter, which solves the technical problem of complicated shell splicing and disassembly in the prior art.

[0029] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the utility model as set forth in the claims.

[0030] Reference Figures 1-6 The utility model provides a combinable optical splitter, including a shell 1, in which a line splitting device is installed. In order to be able to stack multiple shells 1 with line splitting devices installed in the height direction to reduce the footprint, a tenon structure 21 is provided at the upper end of the shell 1, and a slot structure 22 is provided at the lower end. Among them, between the two adjacent shells 1 above and below, the tenon structure 21 of the shell 1 arranged at the lower end is inserted into the slot structure 22 of the shell 1 arranged at the upper end to connect the two shells 1, and the tenon structure 21 slides off the slot structure 22 to enable the upper and lower adjacent shells 1 to be disassembled, thereby avoiding the prior art of connecting two adjacent shells 1 by bolts, which can greatly improve the installation efficiency. At the same time, the number of box combinations can be flexibly adjusted according to actual needs to adapt to diverse and complex application scenarios. When a splitting module fails, the corresponding shell can be quickly removed for repair or replacement without affecting the normal operation of other parts.

[0031] Further optimized, in order to enable the two adjacent shells 1 to contact each other, the tenon structure 21 protrudes from the surface of the shell 1, and the width of the top surface of the tenon structure 21 is wider than the width of the bottom surface of the tenon structure 21;

[0032] The slot structure 22 includes a first groove 221 and a second groove 222 embedded in the surface of the shell 1. The first groove 221 is connected to the second groove 222. The width of the first groove 221 is the same as the width of the top surface of the tenon structure 21, and the width of the bottom surface of the second groove 222 is the same as the width of the first groove 221. The surface area of ​​the top surface of the second groove 222 is smaller than the width of the bottom surface of the second groove 222, so that the tenon structure 21 can be clamped in the second groove 222. In this way, during installation, the tenon structure 21 is first set in the first groove 221, and the tenon structure 21 is moved to the second groove 222 by sliding between the first groove and the second groove. Since the surface area of ​​the top surface of the second groove 222 is smaller than the width of the bottom surface of the second groove 222, the tenon structure 221 can be clamped in the second groove 222.

[0033] To further optimize the solution, a first inclined surface is provided between the top and bottom surfaces of the slot structure 22; a second inclined surface that fits with the first inclined surface is provided between the top and bottom surfaces of the second groove 222. In this way, when people are installing, the top surface of the tenon mechanism 21 is against the bottom surface of the second groove 222, and the bottom surface of the tenon structure 21 is in contact with the top surface of the second groove 222. At the same time, the first inclined surface is fitted with the second inclined surface, which facilitates the connection between the two shells 1.

[0034] A further optimized solution is to facilitate the fastening of the stacked shells 1, a first through hole 23 passing through the shell 1 is provided on the shell 1, and the first through hole 23 is provided in the slot structure 22. Such a setting does not damage the overall structure of the shell 1 and ensures the integrity of the shell.

[0035] To further optimize the solution, in order to facilitate the processing of the shell 1, the tenon structure 21 and the slot structure 22, the tenon structure 21 and the slot structure 22 are set as an integrated structure to form a connecting part 2, wherein the connecting part 2 is installed on the shell 1, and the shell 1 is provided with a mounting hole for installing the connecting part 2. In this way, the shell 1 and the connecting part 2 are processed separately, shortening the processing time of the shell 1. After both are processed, the connecting part 2 can be installed on the shell 1.

[0036] To further optimize the solution, in order to facilitate the tenon structure 21 to be smoothly inserted into the first groove, a gap 13 is provided between the two sides of the mounting holes on both sides of the connector 2, so that it is convenient for people to install the tenon structure 21 in the slot structure 22.

[0037] As a further optimization solution, the shell 1 is generally set to be rectangular, and the tenon structure 21 is provided at four locations, respectively at the four corners of the shell 1. In this way, the shells 1 are ensured to be tightly connected to avoid falling off.

[0038] A further optimized solution is that the shell 1 includes a bottom shell 11 with an opening and a top cover 12. The top cover 12 is arranged at the opening position of the bottom shell 11, and the connecting member 2 is installed on the bottom shell 11, which does not affect the installation of the top cover 12 and the inside of the bottom shell 11.

[0039] A further optimized solution is provided in the bottom shell 11 with an installation cavity, and a third through hole is provided on the side wall of the bottom shell. The first optical fiber 3, the splitter assembly 4, and the second optical fiber 5 are installed in the installation cavity. The splitter assembly 4 splits the first optical fiber 3 into multiple second optical fibers 5, and the other ends of the first optical fiber 3 and the second optical fiber 5 extend out of the bottom shell 11 through the third through hole. With this arrangement, it is possible to decompose multiple second optical fibers from one first optical fiber.

[0040] Further optimization scheme, in order to ensure that the top cover 12 can be firmly installed on the bottom shell 11, a mounting post 14 is provided in the bottom shell 11, and a threaded hole for the screw to pass through is provided on the mounting post 14. A second through hole is provided on the top cover 12, and the screw is fixed in the threaded hole through the second through hole. In this way, the top cover 12 is mounted on the mounting post 14 by the screw to avoid separation between the top cover 12 and the bottom shell 11.
