[0001] The utility model relates to the technical field of optical fiber communication equipment, in particular to a plug-in dustproof structure and an optical fiber coupler. Background Art

[0002] In modern communication and network technology, fiber optic equipment is widely used in data transmission due to its high-speed transmission and high-bandwidth characteristics. However, fiber optic equipment, especially fiber couplers, faces a problem in practical applications: the intrusion of dust and other contaminants. These contaminants may damage the optical components in the fiber optic equipment, resulting in a decrease in signal transmission quality or even equipment failure. Therefore, protecting fiber optic equipment from dust and contaminants is the key to ensure the long-term stable operation of the equipment.

[0003] The existing dustproof structures of optical fiber equipment are usually fixed and difficult to maintain and replace. Once the optical components are contaminated or damaged, the entire equipment often needs to be replaced, which not only increases maintenance costs but may also cause long-term equipment downtime. In addition, the design of some dustproof structures is not user-friendly, making it complicated and inefficient for maintenance personnel to replace dustproof components. Summary of the invention

[0004] The purpose of the utility model is to provide a plug-in dustproof structure and an optical fiber coupler to address the problems existing in the prior art. The bracket can be directly taken out to replace the window piece, which greatly simplifies the maintenance process. Since the window piece can be replaced separately as a consumable, there is no need to replace the entire device, which significantly reduces the maintenance cost.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A pluggable dustproof structure is used for optical fiber equipment, comprising: an equipment housing, a partition is provided inside the housing, the partition is provided with a light-transmitting hole, and a slot is provided on one side of the equipment housing; a bracket is pluggable and installed in the equipment housing through the slot, and the bracket is provided with the mounting hole; a window piece is detachably arranged in the mounting hole and is used to cover the light-transmitting hole.

[0008] Furthermore, the handle is provided with a round hole, which is convenient for taking it in and plugging it out by hand.

[0009] Furthermore, a sealing ring is provided between the plug plate and the partition plate and surrounds the light-transmitting hole to enhance the dust-proof effect.

[0010] Furthermore, the plug plate is provided with an annular embedding groove, and the sealing ring is embedded in the annular embedding groove to limit the position of the sealing ring.

[0011] Furthermore, the cover plate is fixedly connected to the outer side of the device housing by screws.

[0012] Furthermore, a positioning ring is detachably provided in the mounting hole, a positioning ring groove is provided on the inner side of the positioning ring, and the window piece is fixed to the positioning ring by being snapped into the positioning ring groove.

[0013] Furthermore, the mounting hole is provided with an internal thread, the positioning ring is provided with an external thread, and the positioning ring is connected to the mounting hole through threads.

[0014] Furthermore, a sealing gasket is provided at the junction of the bracket and the slot, and the bracket and the slot are sealed and connected via the sealing gasket.

[0015] An optical fiber coupler comprises the above-mentioned pluggable dustproof structure.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The plug-in bracket design makes window replacement simple and quick. The window can be replaced by directly taking out the bracket, which greatly simplifies the maintenance process.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 3 As shown, the first aspect of the present application provides a pluggable dustproof structure for optical fiber equipment, including: an equipment housing 1, which is provided with a partition 2 inside, the partition 2 is provided with a light-transmitting hole 3, and a slot 4 is provided on one side of the equipment housing 1; a bracket 5, which can be plugged in and installed in the equipment housing 1 through the slot 4, and the bracket 5 is provided with a mounting hole; a window piece 6, which is detachably arranged in the mounting hole and is used to cover the light-transmitting hole 3.

[0029] When in use, first fix the window piece 6 in the mounting hole of the bracket 5, and then insert the bracket 5 as a whole into the slot 4. After being inserted into place, the window piece 6 covers the light-transmitting hole 3, thereby sealing and dustproofing the optical path cavity in the left side of the device housing 1 and protecting the internal optical components.

[0030] Since the window sheet 6 is a consumable material, a pluggable bracket 5 is provided. When the window sheet 6 needs to be replaced, the bracket 5 is directly taken out for replacement, and then the bracket 5 is inserted into the device housing 1. After the bracket 5 is inserted into place, the window sheet 6 is automatically positioned so that the window sheet 6 covers the light transmission hole 3 to achieve a dust-proof effect. The pluggable installation of the window sheet 6 is simpler to operate, which greatly facilitates the replacement and maintenance of the window sheet 6.

[0031] In addition, the window sheet 6 is a consumable material and can be replaced individually without replacing the entire device, thereby reducing maintenance costs.

[0032] In some embodiments, the bracket includes: a cover plate 7, which is detachably fixedly connected to the outer side of the device housing 1, such as by screws, snaps, etc., to ensure a firm connection between the bracket 5 and the device housing 1; an insert plate 8, which is arranged on the inner side of the cover plate 7 and is arranged parallel to the partition 2, and the mounting hole is arranged on the insert plate 8. When the bracket 5 is inserted into the slot 4, the insert plate 8 will be close to or close to the partition 2 to ensure that the window 6 is aligned with the light-transmitting hole 3; a handle 9, which is arranged on the outer side of the cover plate 7, and the bracket 5 can be easily pushed into the slot 4 or taken out of the slot 4 by the handle 9.

[0033] In some embodiments, the handle 9 is provided with a round hole for convenient insertion and removal by hand.

[0034] In some embodiments, a sealing ring 10 is provided between the plug plate 8 and the partition plate 2 around the light-transmitting hole 3 to enhance the dust-proof effect. When the bracket 5 is inserted into the slot 4, the sealing ring 10 will tightly surround the light-transmitting hole 3, further preventing dust, moisture and other contaminants from entering the interior of the optical fiber coupler through the light-transmitting hole 3, thereby ensuring the cleanliness and stability of the optical path cavity.

[0035] In some embodiments, an annular groove 11 is provided on the plug plate 8, and the sealing ring 10 is embedded in the annular groove 11 to limit the position of the sealing ring 10. The annular groove 11 provides a stable fixed position for the sealing ring 10, ensuring that the sealing ring 10 will not fall off or shift during the plugging and unplugging process, so that it always remains in the correct position to form an effective sealing barrier; because the sealing ring 10 is fixed in the annular groove 11, the sealing ring 10 can be easily installed and replaced without additional fixing tools or steps, which improves the convenience of maintenance.

[0036] In some embodiments, the cover plate 7 is fixedly connected to the outer side of the device housing 1 by screws 12 .

[0037] In some embodiments, a positioning ring 13 is detachably provided in the mounting hole, and a positioning ring groove is provided on the inner side of the positioning ring 13, and the window sheet 6 is fixed to the positioning ring 13 by being inserted into the positioning ring groove. The positioning ring 13 is designed to fix the window sheet 6, making the replacement of the window sheet 6 more convenient. By pre-fixing the window sheet 6 on the positioning ring 13, the entire combination of the positioning ring 13 and the window sheet 6 can be directly replaced without having to handle the window sheet 6 separately, which greatly reduces the difficulty and complexity of replacing the window sheet for the equipment user; the positioning ring groove on the positioning ring 13 can ensure that the window sheet 6 is in the correct position when fixed, avoiding displacement or tilting of the window sheet 6. At the same time, fixing the window sheet 6 on the positioning ring 13 by ultraviolet glue can further enhance the reliability of the fixation.

[0038] In some embodiments, the mounting hole is provided with an internal thread, the positioning ring 13 is provided with an external thread, the positioning ring 13 is connected to the mounting hole by a threaded connection, and the positioning ring 13 is fixed in the mounting hole by a threaded connection, which can ensure the stability and reliability of the connection, thereby ensuring the stability and dustproof effect of the window panel 6.

[0039] In some embodiments, a sealing gasket is provided at the joint of the bracket 5 and the slot 4, and the bracket 5 and the slot 4 are sealed and connected via the sealing gasket. This can further enhance the dustproof effect of the optical fiber coupler, prevent dust, moisture and other contaminants from entering the interior through the joint, thereby keeping the optical path cavity clean and stable.

[0040] A second aspect of the present application provides a fiber optic coupler, comprising the above-mentioned pluggable dustproof structure.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
