Description

Technical Field

[0001] The utility model relates to the technical field of wavelength division multiplexers, in particular to a wavelength division multiplexer with a dustproof structure. Background Art

[0002] Optical wavelength division multiplexing technology is a communication technology that combines a series of optical signals that carry information but have different wavelengths into one beam and transmits it along a single optical fiber; at the receiving end, some method is used to separate the optical signals of different wavelengths. The wavelength division multiplexer uses this technology, which can transmit multiple signals on a single optical fiber at the same time. Each signal is transmitted by light of a specific wavelength, which is a wavelength channel.

[0003] When the existing wavelength division multiplexer is used, the external parts are directly exposed to the outside, and dust can easily enter the external parts of the wavelength division multiplexer, causing the problem of reduced output energy. Therefore, a wavelength division multiplexer with a dustproof structure is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wavelength division multiplexer with a dustproof structure, which has the advantages of preventing dust from entering the external part, etc., and solves the problem that dust easily enters the external part of the wavelength division multiplexer, causing the output energy to be weakened.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wavelength division multiplexer with a dustproof structure, comprising a body, a plurality of data transmission connectors are arranged on the front side of the body, a warehouse body is fixedly installed on the outside of the data transmission connector on the front side of the body and on the right side, a plurality of through holes are opened on the front side of the warehouse body, a fixing mechanism is arranged inside the warehouse body, and a shielding mechanism is arranged on the front side of the warehouse body to prevent dust from entering the inside of the idle data transmission connector.

[0006] Furthermore, the shielding mechanism includes a shielding plate, a dust plug, a first magnetic block and a second magnetic block. The shielding plate is movably installed on the front side of the warehouse body and located outside the through hole. The dust plug with one end extending into the through hole is fixedly installed at the center of the back side of the shielding plate. The first magnetic block is fixedly installed on the front side of the warehouse body and located on the left and right sides of the through hole. Two second magnetic blocks are fixedly installed on the bottom end of the back side of the shielding plate, and the first magnetic block and the second magnetic block are magnetically attracted to each other.

[0007] Furthermore, the fixing mechanism includes a U-shaped plate, a first clamping block, a second clamping block and a threaded rod, a U-shaped plate is slidably installed inside the warehouse body and on the outside of the data transmission connector, a first clamping block with one end penetrating the U-shaped plate and extending to the left side of the data transmission connector is fixedly installed on the inner top wall of the warehouse body, a second clamping block is fixedly installed on the inner top wall of the U-shaped plate and on the right side of the data transmission connector, and a threaded rod with one end penetrating and extending to the left side of the warehouse body is rotatably installed on the left side of the U-shaped plate.

[0008] Furthermore, a threaded sleeve is embedded in the left center of the warehouse body, and the threaded rod is threadedly connected to the inside of the threaded sleeve.

[0009] Furthermore, a sliding hole is provided on the top of the U-shaped plate, and the sliding hole matches the first clamping block.

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

[0011] 1. The wavelength division multiplexer with dust-proof structure has a shielding mechanism, so that when in use, the bin body, the shielding plate and the dust plug can keep the data transmission connector in a relatively sealed state to prevent dust from entering the data transmission connector; in addition, when the connector needs to be plugged in, it is only necessary to flip the shielding plate in the relative position to make the first magnetic block separate from the second magnetic block to release the shielding state of the through hole. When the connector is removed, the shielding plate is flipped downward to make the first magnetic block contact with the second magnetic block to complete the shielding of the through hole, which is very convenient to use.

[0012] 2. The wavelength division multiplexer with a dust-proof structure can firmly fix the connector by the first clamping block and the second clamping block through the setting of the fixing mechanism, so as to avoid the connector from loosening during use; in addition, after the first clamping block and the second clamping block clamp the connector, they can cover the through hole to prevent dust from entering through the gap between the connector and the through hole, thereby improving the sealing of the data transmission connector.

It is very convenient to use.

[0023] In this embodiment, the fixing mechanism 5 includes a U-shaped plate 51, a first clamping block 52, a second clamping block 53 and a threaded rod 54.
