Description

Technical Field

[0001] The utility model relates to the technical field of wavelength division multiplexers, in particular to a packaging component for a wavelength division multiplexer. Background Art

[0002] A wavelength division multiplexer is a network transmission technology device. Its core technology is to combine a series of optical signals carrying information but with different wavelengths into one beam and transmit them along a single optical fiber. At the receiving end, it will use a specific method to separate the optical signals of different wavelengths again. Through this technology, the wavelength division multiplexer can achieve the purpose of transmitting a large number of high-bandwidth signals on a single optical fiber. In actual use, wavelength division multiplexers are mostly packaged in a box for use, which can protect the wavelength division multiplexer and optical fiber.

[0003] In the process of implementing the present application, the inventors have found that there are at least the following problems in the technology: the optical fiber of the existing wavelength division multiplexer is generally placed directly inside its packaging box, and the optical fiber is only simply positioned. However, the wavelength division multiplexer will inevitably produce collisions and extrusions during logistics transportation, causing the simply fixed optical fiber to spread out, making the routing disordered and not conducive to subsequent maintenance. Therefore, it is necessary to propose a packaging component for a wavelength division multiplexer to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a packaging component for a wavelength division multiplexer, which has advantages such as independent wiring, and solves the problem that the existing wavelength division multiplexer packaging box has a poor optical fiber positioning effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging component for a wavelength division multiplexer, comprising a protection mechanism, wherein a winding mechanism is arranged inside the protection mechanism;

[0006] The winding mechanism includes a positioning seat, which is detachably mounted on the rear side of the inner wall of the protective mechanism, a groove is provided on the top of the positioning seat, a fastening screw is inserted on the rear side of the inner wall of the groove, a sliding groove is provided on the top of the positioning seat and outside the groove, an annular slider is slidably mounted inside the sliding groove, a winding threaded tube with one end passing through and extending to the front side of the positioning seat is fixedly mounted on the front side of the annular slider, two positioning plates are mounted on the external threads of the winding threaded tube, and a resistance-increasing pattern is provided on the back side of the annular slider.

[0007] Furthermore, the protective mechanism includes a packaging shell, a top cover is detachably installed on the front of the packaging shell, a wavelength division multiplexer body is fixedly installed on the rear side of the inner wall of the packaging shell, a connector is embedded in the bottom of the packaging shell, and a transmission optical fiber with one end connected to the wavelength division multiplexer body is arranged inside the connector.

[0008] Furthermore, the transmission optical fiber is wound around the outside of the winding threaded tube, and the transmission optical fiber is located between two positioning plates.

[0009] Furthermore, the height of the annular sliding block is smaller than the height of the sliding groove, and the front side of the winding threaded tube is in contact with the top cover.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The packaging component for the wavelength division multiplexer enables the transmission optical fiber to be independently arranged and fixed by setting a winding mechanism and a protection mechanism, and tries to avoid the transmission optical fiber from spreading during logistics transportation, making subsequent maintenance convenient and extending the service life.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 In this embodiment, a packaging component for a wavelength division multiplexer includes a protective mechanism, and a winding mechanism is arranged inside the protective mechanism.

[0017] In this embodiment, the protective mechanism includes a packaging shell 1, a top cover 2 is detachably installed on the front of the packaging shell 1, a wavelength division multiplexer body 3 is fixedly installed on the rear side of the inner wall of the packaging shell 1, a connector 4 is embedded in the bottom of the packaging shell 1, and a transmission optical fiber 5 with one end connected to the wavelength division multiplexer body 3 is arranged inside the connector 4.

[0018] The number of connectors 4 can be adjusted according to actual usage, and the packaging shell 1 effectively protects the wavelength division multiplexer body 3 .

[0019] In this embodiment, the winding mechanism includes a positioning seat 6, which is detachably mounted on the rear side of the inner wall of the protective mechanism. A groove 7 is provided on the top of the positioning seat 6, and a fastening screw 8 is inserted on the rear side of the inner wall of the groove 7. A slide groove 9 is provided on the top of the positioning seat 6 and located outside the groove 7. An annular slider 10 is slidably installed inside the slide groove 9. A winding threaded tube 11 with one end passing through and extending to the front side of the positioning seat 6 is fixedly installed on the front side of the annular slider 10. Two positioning plates 12 are installed on the external threads of the winding threaded tube 11. A resistance increasing pattern is provided on the back side of the annular slider 10. The transmission optical fiber 5 is wound around the outside of the winding threaded tube 11. The transmission optical fiber 5 is located between the two positioning plates 12. The height of the annular slider 10 is less than the height of the slide groove 9, and the front side of the winding threaded tube 11 is in contact with the top cover 2.

[0020] Specifically, first, the rear positioning plate 12 is threadedly installed on the outside of the winding threaded tube 11, and then, the transmission optical fiber 5 is wound around the outside of the winding threaded tube 11, and then, the front positioning plate 12 is threadedly installed so that the transmission optical fiber 5 is confined between the front and rear positioning plates 12. At this time, the winding threaded tube 11 is rotated to make the annular slider 10 slide in the slide groove 9 to wind up the loosely wound transmission optical fiber 5. Finally, when the top cover 2 is fixed to the front side of the packaging shell 1, the top cover 2 applies pressure to the winding threaded tube 11 to move the winding threaded tube 11 backward, so that the back side of the annular slider 10 contacts the rear side of the inner wall of the slide groove 9, and the friction is increased by the resistance increasing pattern to fix it, thereby achieving stable positioning of the transmission optical fiber 5.

[0021] It should be noted that the number of winding mechanisms can be adjusted according to actual usage conditions, wherein a plurality of transmission optical fibers 5 can be fixed on one winding mechanism, and positioning plates 12 can be used to separate the transmission optical fibers 5, so as to make the usage flexible.

[0022] The positioning seat 6 is fixedly connected to the packaging shell 1 by means of a fastening screw 8, so that the position of the winding mechanism can be flexibly adjusted.
