The first sealing plate 20 and the second sealing plate 30 may be metal elastic sheets, for example: spring steel, beryllium bronze, phosphor bronze; but also non-metallic elastic sheets, for example: rubber; preferably, the first sealing plate 20 and the second sealing plate 30 are plastic thin plates, and compared with metal elastic plates, the plastic thin plates have low cost, good toughness and high deformation resistance, and prevent the first sealing plate 20 and the second sealing plate 30 from generating elastic fatigue and being unable to recover to the original shape, so that the plugging channel 103 is unable to be plugged. Further, the first sealing plate 20 and the second sealing plate 30 are transparent plastic sheets, so that an operator can see whether an abnormality exists inside the plugging channel 103 through the first sealing plate 20 and the second sealing plate 30 and can timely handle the abnormality.

In addition, the length of the first sealing plate 20 and the second sealing plate 30 is not limited in this embodiment, and the length of the first sealing plate 20 and the length of the second sealing plate 30 may be the same, and at this time, the second end of the first sealing plate 20 and the second end of the second sealing plate 30 are located on the central line of the plugging channel 103 at the same time; the lengths of the first sealing plate 20 and the second sealing plate 30 may be different, and the second end of the first sealing plate 20 and the second end of the second sealing plate 30 have a gap from the center line of the insertion passage 103. It should be noted that when a gap exists between the second ends of the first and second sealing plates 20 and 30 and the center line of the plug passageway 103, the shorter one of the two is attached to the sidewall of the plug passageway 103 first when the fiber optic connector 40 is inserted.
Continuing to refer to fig. 3, in the working process, during signal transmission, an operator inserts the optical fiber connector 40 into the insertion end 101 from the first opening, and when the optical fiber connector 40 abuts against the first sealing plate 20 and the second sealing plate 30, the optical fiber connector continues to be inserted toward the connecting end 102, and the first sealing plate 20 and the second sealing plate 30 are stressed to be bent until the first sealing plate 20 and the second sealing plate 30 are bent and attached to the side wall of the insertion passage 103; when the signal transmission is stopped, the operator pulls the optical fiber connector 40 towards the plugging end 101, along with the pulling of the optical fiber connector 40, the first sealing plate 20 and the second sealing plate 30 rebound simultaneously under the action of elastic force until the optical fiber connector 40 moves to the plugging end 101, and the first sealing plate 20 and the second sealing plate 30 completely reset to plug the plugging channel 103 again.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of an optical module according to an embodiment of the present invention. In another implementation manner, the side of the first sealing plate 20 facing the plug end 101 and the side of the second sealing plate 30 facing away from the plug end 101 are disposed in a coplanar manner, so that the plug channel 103 is blocked, and dust and water vapor in the air cannot pass through the first sealing plate 20 and the second sealing plate 30, thereby preventing the dust and water vapor from entering the inside of the optical module. Compared with the previous mode, the dust-proof effect is better when part of the first sealing plate 20 is overlapped with part of the second sealing plate 30.
Taking the orientation shown in fig. 4 as an example, during operation, during signal transmission, an operator inserts the optical fiber connector 40 into the insertion end 101 from the first opening, when the optical fiber connector 40 abuts against the second sealing plate 30, the optical fiber connector continues to be inserted in the direction of the connection end 102, the second sealing plate 30 applies a pushing force to the first sealing plate 20 under the abutting action of the optical fiber connector 40, the first sealing plate 20 is forced to bend, and then the second sealing plate 30 bends; continuing to insert, the shorter one of the first sealing plate 20 and the second sealing plate 30 is attached to the side wall of the plugging channel 103; the insertion is continued until the longer of the two also abuts against the side wall of the plug channel 103. When the signal transmission is stopped, the operator pulls the optical fiber connector 40 towards the direction of the plugging end 101, and along with the pulling of the optical fiber connector 40, the longer one of the two rebounds under the action of elastic force; continuing to pull the optical fiber connector 40 while the end of the optical fiber connector 40 facing the connection end 102 is flush with the second end of the shorter of the two, the shorter of the two rebounding under the action of the elastic force; until the optical fiber connector 40 moves to the plugging end 101, the first sealing plate 20 and the second sealing plate 30 are completely restored, and the plugging channel 103 is plugged again.
Referring to fig. 5, fig. 5 is a schematic cross-sectional view of an optical module according to an embodiment of the present invention. In yet another implementation, the side of the first seal plate 20 facing away from the mating end 101 is disposed coplanar with the side of the second seal plate 30 facing toward the mating end 101. The working process is similar to that of the previous implementation mode, and is not described herein again.

In addition, the interface position of the second groove 1032 and the second fixing groove may also be rounded.
On the basis of the above embodiment, the plurality of plugging channels 103 may be provided, and the plurality of plugging channels 103 are arranged in parallel and at intervals, so that the optical module may be connected to the plurality of optical fiber connectors 40 at the same time, and the signal transmission efficiency is improved. A first sealing plate 20 and a second sealing plate 30 are arranged in each plugging channel 103, the first sealing plate 20 in the previous plugging channel 103 and the first sealing plate 20 in the next plugging channel 103 in the adjacent plugging channels 103 are symmetrically arranged, and the second sealing plate 30 in the previous plugging channel 103 and the second sealing plate 30 in the next plugging channel 103 in the adjacent plugging channels 103 are symmetrically arranged; of course, the arrangement of the first sealing plate 20 and the second sealing plate 30 in each plugging channel 103 may be asymmetric to the arrangement of the first sealing plate 20 and the second sealing plate 30 in the adjacent plugging channel 103, or even different.
With continued reference to fig. 2 to 5, when there are two plugging channels 103 and the arrangement of the first sealing plate 20 and the second sealing plate 30 in adjacent plugging channels 103 are symmetrical, the second sealing plate 30 in the previous plugging channel 103 in the adjacent plugging channels 103 is integrally formed with the second sealing plate 30 in the next plugging channel 103. Through the arrangement, the second sealing plate 30 in the previous inserting channel 103 and the second sealing plate 30 in the next inserting channel 103 are of an integral structure, and the strength is high. Of course, the first sealing plate 20 in the previous plug channel 103 and the first sealing plate 20 in the next plug channel 103 in the adjacent plug channels 103 may be integrally formed.
Referring to fig. 6, fig. 6 is a cross-sectional view of an optical module having three plug channels 103 according to an embodiment of the present invention. When the number of the plugging channels 103 is three and the arrangement modes of the first sealing plate 20 and the second sealing plate 30 in the adjacent plugging channels 103 are symmetrical, the first sealing plate 20 in the previous plugging channel 103 and the first sealing plate 20 in the next plugging channel 103 in the adjacent plugging channels 103 are integrally formed; meanwhile, the second sealing plate 30 in the previous plugging channel 103 in the adjacent plugging channels 103 is integrally formed with the second sealing plate 30 in the next plugging channel 103.
