Description

Technical Field

[0001] The present disclosure relates to the technical field of optical modules, and in particular to a dustproof component and an optical module assembly. Background Art

[0002] The optical module is used to be plugged into the communication equipment and docked with the optical fiber connector. The optical module can convert the electrical signal generated by the communication equipment into an optical signal, send the optical signal to the outside through the optical fiber connected to the optical port, and receive the optical signal through the optical fiber connected to the optical port, then convert the optical signal into an electrical signal and send it to the communication equipment.

[0003] In actual applications, the optical port of the optical module may be contaminated by dust or other dirt, which may cause the optical power of the optical signal received and sent by the optical module to attenuate. Summary of the invention

[0004] The present disclosure provides a dustproof component and an optical module assembly. The dustproof component can seal the optical port of the optical module, and when the optical fiber connector is inserted into the passage of the dustproof component, the optical fiber connector can automatically push open the baffle and be inserted into the optical port, which is very easy to operate. The technical solutions of the dustproof component and the optical module assembly are as follows.

[0005] In a first aspect, the present disclosure provides a dustproof component. The dustproof component includes a housing and at least one baffle assembly. The baffle assembly includes a first baffle and a second baffle. The housing has at least one channel, and the channel is used to communicate with an optical port of an optical module. The first baffle and the second baffle are used to close the channel, and the two opposite sides of the first baffle and the second baffle are respectively rotatably connected to the housing, and the first baffle and the second baffle can open the channel by rotating toward the inside of the channel.

[0006] The first baffle and the second baffle are rotatably connected to the shell at opposite sides thereof. It can also be described that the first baffle and the second baffle close and open the passage in the form of a split door (or double door).

[0007] The technical solution provided by the present disclosure, since the first baffle and the second baffle can open the channel by rotating toward the inside of the channel, during the docking process between the optical fiber connector and the optical module, the optical fiber connector can push the first baffle and the second baffle to automatically open the channel and smoothly insert into the optical port of the optical module. During the docking process, the user does not need to manually operate the first baffle and the second baffle to open the channel, the user's operation is very simple, and the efficiency of existing network deployment is improved.

[0008] In addition, since the channel serves to accommodate the first baffle plate and the second baffle plate in the open state, the size of the first baffle plate and the second baffle plate will affect the size of the channel. Compared with using one baffle plate to close the channel, the disclosure can reduce the length of the channel by setting the first baffle plate and the second baffle plate to close the channel, which is conducive to the miniaturization design of the dustproof component.

[0009] In a possible implementation, the first baffle has a first recessed portion, the second baffle has a second recessed portion, and when the first baffle and the second baffle close the channel, the first recessed portion and the second recessed portion form an escape groove. The escape groove is configured to accommodate the optical fiber ferrule of the optical fiber connector during the process of inserting the optical fiber connector into the channel, so that the first baffle and the second baffle are pushed open by the connector housing of the optical fiber connector.

[0010] The technical solution provided by the present disclosure provides an avoidance groove, so that when the optical fiber connector is inserted into the passage of the dustproof component, the optical fiber ferrule of the optical fiber connector will not contact the first baffle plate and the second baffle plate, but the connector housing of the optical fiber connector contacts the first baffle plate and the second baffle plate, and pushes the first baffle plate and the second baffle plate away. In this way, it is not easy to cause dirt and damage to the optical fiber ferrule.

[0011] Furthermore, by arranging the first recessed portion and the second recessed portion forming the avoidance groove to be located on different baffles, the avoidance groove will be split into two parts (the first recessed portion and the second recessed portion) during the process of the connector housing pushing open the first baffle and the second baffle, so that the optical fiber ferrule will not be stuck in the avoidance groove. It is understandable that if the avoidance groove is set on one baffle, since the avoidance groove will not be split into two parts, the optical fiber ferrule will be stuck in the avoidance groove, so that the connector housing cannot push open the baffle.

[0012] In a possible implementation, the depth of the avoidance groove is greater than the length of the optical fiber ferrule extending relative to the connector housing.

[0013] In a possible implementation, the avoidance groove includes a tapered portion, and the inner diameter of the tapered portion gradually decreases along the depth direction of the avoidance groove, wherein the depth direction of the avoidance groove is the direction in which the optical fiber ferrule extends into the avoidance groove.

[0014] The technical solution provided by the present disclosure, by providing an avoidance groove including a tapered portion, makes the inner diameter of one end of the avoidance groove opening larger, so that the optical fiber ferrule is not easy to accidentally touch the inner wall of the avoidance groove during the process of extending into the avoidance groove, thereby reducing the possibility of damage to the optical fiber ferrule and the requirement for user operation accuracy, thereby indirectly improving operation efficiency.

[0015] In a possible implementation, the avoidance groove further includes a cylindrical portion, and the cylindrical portion is connected to the small-diameter end of the tapered portion.

[0016] In a possible implementation, the housing has two channels, which are respectively used to communicate with the optical transmission port and the optical receiving port of the optical module. The dustproof component includes two baffle assemblies, which are respectively used to close the two channels.

[0017] The technical solution provided by the present disclosure provides a dustproof component with two channels and two baffle assemblies, so that the opening and closing of the two channels are independent. In this way, during the process of plugging and unplugging the optical fiber connector in the optical transmission port, the dustproof of the optical receiving port will not be affected. Similarly, during the process of plugging and unplugging the optical fiber connector in the optical receiving port, the dustproof of the optical transmission port will not be affected. It can be seen that the above design improves the dustproof effect of the dustproof component.

[0018] In a possible implementation, the housing has a channel, and the channel is used to communicate with both the optical transmitting port and the optical receiving port of the optical module. The dustproof component includes a baffle assembly.

[0019] The technical solution provided by the present disclosure reduces the number of baffle components included in the dustproof component by setting a channel connected to both the optical transmission port and the optical receiving port, which is conducive to reducing the cost of the dustproof component. In addition, generally speaking, the optical transmission port and the optical receiving port need to be used at the same time. Therefore, in most cases, there will not be a situation where one optical port is inserted with an optical fiber connector, while the other optical port is not inserted with an optical fiber connector, and the baffle component opens the channel.

[0020] In a possible implementation, the first baffle has two first recessed portions, and the second baffle has two second recessed portions. When the first baffle and the second baffle close the channel, the two first recessed portions and the two second recessed portions form two avoidance grooves. The avoidance groove is configured to accommodate the optical fiber ferrule of the optical fiber connector during the process of inserting the optical fiber connector into the channel, so that the first baffle and the second baffle are pushed open by the connector housing of the optical fiber connector. The baffle assembly is opposite to both the optical transmitting port and the optical receiving port. The two avoidance grooves are opposite to the optical transmitting port and the optical receiving port, respectively. The two avoidance grooves are respectively used to accommodate the optical fiber ferrules of the two optical fiber connectors.

[0021] In a possible implementation, the housing has a channel, and the channel is used to communicate with the optical bidirectional transmission port of the optical module. The dustproof component includes a baffle assembly.

[0022] In a possible implementation, the dustproof component further includes a first elastic member and a second elastic member. The first elastic member and the second elastic member are used to drive the first baffle plate and the second baffle plate to close the channel.

[0023] The technical solution provided by the present disclosure, in the process of pulling out the optical fiber connector, under the action of the elastic force of the first elastic member and the second elastic member, the first baffle and the second baffle gradually rotate toward the outside of the channel and abut against the connector housing of the optical fiber connector, so that the first baffle and the second baffle can close the channel in time, improving the dustproof effect of the dustproof component. In addition, the user does not need to manually operate the first baffle and the second baffle to close the channel after pulling out the optical fiber connector, which further simplifies the user's operation.

[0024] In a possible implementation, the first elastic member and the second elastic member are both torsion springs. The first baffle is rotatably connected to the housing via a first mounting shaft, the first elastic member is encircled by the first mounting shaft, and two torsion arms are respectively against the first baffle and the housing. The second baffle is rotatably connected to the housing via a second mounting shaft, the second elastic member is encircled by the second mounting shaft, and two torsion arms are respectively against the second baffle and the housing.

[0025] In a possible implementation, the dustproof component further includes a pressing block. The pressing block is movably connected to the housing. When the optical fiber connector is inserted into the channel, the locking mechanism of the optical fiber connector is located on the movable path of the pressing block, and the pressing block is configured to press the locking mechanism.

[0026] The technical solution provided by the present disclosure, by providing a pressing block, allows the user to press the locking mechanism of the optical fiber connector by operating the pressing block to release the locking state of the locking mechanism, so that the optical fiber connector can be smoothly pulled out from the optical port.

[0027] In a possible implementation, the pressing block is located on the insertion path of the locking mechanism of the optical fiber connector, and the pressing block is further configured to be lifted up by the locking mechanism during the process of inserting the optical fiber connector into the channel.

[0028] In a possible implementation manner, the pressing block is rotatably connected to the shell.

[0029] In a possible implementation, the housing further has two snap-in strips, which are used to snap-in to the grooves of the two side walls of the optical module. In this way, the dustproof component can be snap-in to the optical module, so that the dustproof component is not easily lost.

[0030] In a possible implementation, the housing has two support arms, and the distance between the two support arms is greater than the distance between the two side walls of the optical module. The two clamping strips are respectively located on the inner sides of the two support arms.

[0031] In a possible implementation, the optical module includes an optical module body and a handle bar. Two side walls of the optical module body have grooves, and the groove has an opening at the end of the optical module body. When the handle bar is in a locked state, the handle bar closes the opening of the groove. When the handle bar is in an unlocked state, there is a gap between the handle bar and the end of the optical module body, and the groove is connected to the gap through the opening. The snap-in strip is used to enter and exit the groove through the gap.

[0032] The dustproof component is installed on the optical module in the following manner. The first step is to pull open the handle bar so that there is a gap between the handle bar and the end of the optical module body. The second step is to align the snap-in strip of the dustproof component with the gap and allow the snap-in strip to enter the gap. The third step is to slide the dustproof component so that the snap-in strip slides from the gap into the groove. The fourth step is to tighten the handle bar so that the handle bar closes the opening of the groove, and the snap-in strip of the dustproof component is confined in the groove, and the installation of the dustproof component is completed.

[0033] The technical solution provided by the present disclosure utilizes the existing groove on the optical module, and utilizes the phenomenon that when the handle bar is in a locked state, the handle bar closes the opening of the groove, and when the handle bar is in an unlocked state, there is a gap between the handle bar and the end of the optical module body, so that the clamping strip of the dustproof component can enter and exit the groove through the gap, realizing the non-destructive disassembly and assembly of the dustproof component. In addition, the above connection method does not require improvement of the structure of the optical module, so that the dustproof component provided by the present disclosure can be compatible with the existing optical module.

[0034] In a possible implementation, the housing includes a main body, two connecting parts, two support arms and two snap-in strips. The main body has a channel. The two support arms are connected to two sides of the main body through the two connecting parts. The two snap-in strips are respectively located on the inner sides of the two support arms.

[0035] In a possible implementation manner, the main body is movably connected to the pressing block.

[0036] In a possible implementation, the width of the main body is smaller than the distance between the two inner side walls of the handle bar, so that the main body can extend between the two inner side walls of the handle bar.

[0037] In a possible implementation, the distance between the two support arms is greater than the distance between the two side walls of the optical module body, so that the two support arms can be buckled on the optical module body.

[0038] In a possible implementation, the distance between the two support arms is greater than the distance between the two outer side walls of the handle bar, so that the two support arms can be buckled on the optical module body.

[0039] In a possible implementation, the distance between the two clamping strips is smaller than the distance between the two outer side walls of the optical module body, so that the two clamping strips can be clamped in the grooves of the two outer side walls of the optical module body.

[0040] In a possible implementation, the housing of the dustproof component is integrally connected to the housing of the optical module. Alternatively, it can be understood that the housing of the dustproof component is integrally formed with the housing of the optical module.

[0041] In a second aspect, the present disclosure provides another dustproof component. The dustproof component includes a housing and at least one baffle assembly. The housing has at least one channel and two snap-in strips. The channel is used to communicate with the optical port of the optical module, and the baffle assembly is used to close the channel. The two snap-in strips are used to snap-in with the grooves on both sides of the optical module.

[0042] The technical solution provided by the present disclosure realizes the dustproof function of the optical module by setting a baffle assembly to close the channel, so that the dustproof component can close the optical port of the optical module. In addition, by setting the housing with two snap-on strips, the dustproof component can be snap-on to the optical module, reducing the possibility of losing the dustproof component.

[0043] In a possible implementation, the optical module includes an optical module body and a handle bar. Two side walls of the optical module body have grooves, and the groove has an opening at the end of the optical module body. When the handle bar is in a locked state, the handle bar closes the opening of the groove. When the handle bar is in an unlocked state, there is a gap between the handle bar and the end of the optical module body, and the groove is connected to the gap through the opening. The snap-in strip is used to enter and exit the groove through the gap.

[0044] The dustproof component is installed on the optical module in the following manner. The first step is to pull open the handle bar so that there is a gap between the handle bar and the end of the optical module body. The second step is to align the snap-in strip of the dustproof component with the gap and allow the snap-in strip to enter the gap. The third step is to slide the dustproof component so that the snap-in strip slides from the gap into the groove. The fourth step is to tighten the handle bar so that the handle bar closes the opening of the groove, and the snap-in strip of the dustproof component is confined in the groove, and the installation of the dustproof component is completed.

[0045] The technical solution provided by the present disclosure utilizes the existing groove on the optical module, and utilizes the phenomenon that when the handle bar is in a locked state, the handle bar closes the opening of the groove, and when the handle bar is in an unlocked state, there is a gap between the handle bar and the end of the optical module body, so that the clamping strip of the dustproof component can enter and exit the groove through the gap, realizing the non-destructive disassembly and assembly of the dustproof component. In addition, the above connection method does not require improvement of the structure of the optical module, so that the dustproof component provided by the present disclosure can be compatible with the existing optical module.

[0046] In a possible implementation, the housing includes a main body, two connecting parts, two support arms and two snap-in strips. The main body has a channel. The two support arms are connected to two sides of the main body through the two connecting parts. The two snap-in strips are respectively located on the inner sides of the two support arms.

[0047] In a possible implementation, the width of the main body is smaller than the distance between the two inner side walls of the handle bar, so that the main body can extend between the two inner side walls of the handle bar.

[0048] In a possible implementation, the distance between the two support arms is greater than the distance between the two side walls of the optical module body, so that the two support arms can be buckled on the optical module body.

[0049] In a possible implementation, the distance between the two support arms is greater than the distance between the two outer side walls of the handle bar.

[0050] In a possible implementation, the distance between the two clamping strips is smaller than the distance between the two outer side walls of the optical module body, so that the two clamping strips can be clamped in the grooves of the two outer side walls of the optical module body.

[0051] In a possible implementation manner, the dustproof component is the same as the dustproof component of the first aspect.

[0052] In a third aspect, the present disclosure provides an optical module assembly, which includes an optical module and a dustproof component as described in any one of the first aspect or the second aspect, wherein the dustproof component is connected to the optical module, and a channel of the dustproof component is connected to an optical port of the optical module.

[0053] In a possible implementation, the optical port of the optical module includes an optical transmission port and an optical receiving port. The housing has two channels, which are respectively connected to the optical transmission port and the optical receiving port.

[0054] In a possible implementation, the optical port of the optical module includes an optical transmission port and an optical receiving port. The housing has a channel, and the channel is connected to both the optical transmission port and the optical receiving port.

[0055] In a possible implementation, the optical port of the optical module is an optical bidirectional transmission port. The housing has a channel, and the channel is connected to the optical bidirectional transmission port.

[0056] In a possible implementation, two side walls of the optical module have grooves. The housing includes two clamping strips, and the two clamping strips are used to be clamped in the grooves of the two side walls of the optical module.

[0057] In a possible implementation, the optical module includes an optical module body and a handle bar. Two side walls of the optical module body have grooves, and the groove has an opening at the end of the optical module body. When the handle bar is in a locked state, the handle bar closes the opening of the groove. When the handle bar is in an unlocked state, there is a gap between the handle bar and the end of the optical module body, and the opening of the groove is connected to the gap. The snap-in strip is used to enter and exit the groove through the gap.

[0058] In a possible implementation, the dustproof component is connected to the optical module in an integrated manner. In this case, the optical module assembly is the optical module.

[0094] The optical module is used to be plugged into the communication equipment and docked with the optical fiber connector. The optical module can convert the electrical signal generated by the communication equipment into an optical signal, send the optical signal to the outside through the optical fiber connected to the optical port, and receive the optical signal through the optical fiber connected to the optical port, then convert the optical signal into an electrical signal and send it to the communication equipment.

[0095] In actual applications, the optical port of the optical module may be contaminated by dust, which will cause the optical power of the optical signal received and sent by the optical module to attenuate, thereby affecting the link performance. Therefore, the optical module needs to have a good dustproof function. The following two technical solutions are used in related technologies to achieve dustproof of the optical port of the optical module.

[0096] The first one, such as Figure 1 As shown, the optical module 1 is softly connected with the dust plug 4. When the optical module 1 needs to be connected to the optical fiber connector, the dust plug 4 is pulled out. When the optical module 1 is not in use, the dust plug 4 is inserted into the optical port of the optical module 1.

[0097] However, the first technical solution has the following technical problems. First, when docking the optical module 1 with the optical fiber connector, you first need to manually pull out the dust plug 4 on the optical module 1, and then insert the optical fiber connector. After pulling out the optical fiber connector, you also need to manually insert the dust plug 4 into the optical port of the optical module 1. This reduces the efficiency of the deployment of the optical module 1. Second, the dust plug 4 and the optical module 1 are two separate materials. After the dust plug 4 is pulled out of the optical module 1, it is easy to lose. Moreover, once the dust plug 4 is lost, it is very likely that it will not be installed again, which makes the optical port of the optical module 1 very easy to get dirty.

[0098] The second type, such as Figure 2As shown, a dustproof component is provided which is integrated with the housing of the optical module. The dustproof component has a baffle 5 which can close the optical port 111 of the optical module 1 , and a user can manually open or close the baffle 5 .

[0099] However, the second technical solution has the following technical problems. First, when docking the optical module 1 with the optical fiber connector, the baffle 5 needs to be opened manually first, and then the optical fiber connector is inserted. This reduces the efficiency of the deployment of the optical module 1. Second, the integrated design of the optical module housing and the dustproof component requires a special design of the optical module housing, which is not compatible with existing optical modules. In addition, once the dustproof component is damaged, the entire optical module needs to be replaced.

[0100] In view of the above technical problems, Figure 3 and Figure 4 As shown, the embodiment of the present disclosure provides a dustproof component 2, which can seal the optical port 111 of the optical module 1, and in the process of connecting the optical fiber connector 3 with the optical module 1, there is no need to manually open the optical port 111 of the optical module 1, and the operation is very simple. Below, the dustproof component 2 provided in the embodiment of the present disclosure is exemplarily described.

[0101] like Figure 5-Figure 7 As shown, the dustproof component 2 includes a housing 21 and a baffle assembly 22. The baffle assembly 22 includes a first baffle 221 and a second baffle 222. The housing 21 has a channel 210, and the channel 210 is used to communicate with the optical port 111 of the optical module 1. The first baffle 221 and the second baffle 222 are used to close the channel 210, and the first baffle 221 and the second baffle 222 are respectively connected to the housing 21 at opposite sides, and the first baffle 221 and the second baffle 222 can open the channel 210 by rotating toward the inside of the channel 210.

[0102] The first baffle 221 and the second baffle 222 are rotatably connected to the shell 21 at opposite sides thereof. It can also be described that the first baffle 221 and the second baffle 222 close and open the channel 210 in the form of a split door (or double door).

[0103] The technical solution provided by the embodiment of the present disclosure is that the first baffle 221 and the second baffle 222 can open the channel 210 by rotating toward the inside of the channel 210. Figure 8 and Fig. 9 As shown, during the docking process between the optical fiber connector 3 and the optical module 1, the optical fiber connector 3 can push the first baffle 221 and the second baffle 222 to automatically open the channel 210, so that the optical fiber connector 3 can be smoothly inserted into the optical port 111 of the optical module 1. During the docking process, the user does not need to manually operate the first baffle 221 and the second baffle 222 to open the channel 210, the user's operation is very simple, and the deployment efficiency of the existing network is improved.

[0104] In addition, if Figure 8 and Fig. 9 As shown, since the channel 210 needs to accommodate the first baffle 221 and the second baffle 222 in the open state, the size of the first baffle 221 and the second baffle 222 will affect the size of the channel 210. However, the embodiment of the disclosure provides the first baffle 221 and the second baffle 222 to close the channel 210, which can reduce the length of the channel 210 compared with using one baffle to close the channel 210, which is conducive to the miniaturization design of the dustproof component 2.

[0105] like Figure 8 and Fig. 9 As shown, during the docking process between the optical fiber connector 3 and the optical port 111 of the optical module 1, the optical fiber connector 3 will contact the first baffle 221 and the second baffle 222. The optical fiber ferrule 31 of the optical fiber connector 3 is used to dock with the optical port 111 of the optical module 1, and the optical fiber ferrule 31 protrudes from the connector housing 32 of the optical fiber connector 3. Therefore, the optical fiber ferrule 31 may be dirty or damaged due to contact with the baffle assembly 22.

[0106] In order to prevent the optical fiber ferrule 31 from contacting the baffle assembly 22, in some examples, such as Figure 6-Figure 13 As shown, the first baffle 221 has a first recessed portion 2211, and the second baffle 222 has a second recessed portion 2221. When the first baffle 221 and the second baffle 222 close the channel 210, the first recessed portion 2211 and the second recessed portion 2221 form an escape groove 220. The escape groove 220 is configured to accommodate the optical fiber ferrule 31 of the optical fiber connector 3 during the process of inserting the optical fiber connector 3 into the channel 210, so that the first baffle 221 and the second baffle 222 are pushed open by the connector housing 32 of the optical fiber connector 3. The inner diameter of the escape groove 220 is greater than the outer diameter of the optical fiber ferrule 31.

[0107] The technical solution provided by the embodiment of the present disclosure, by providing the above-mentioned avoidance groove 220, makes it possible that during the process of inserting the optical fiber connector 3 into the channel 210 of the dustproof component 2, the optical fiber ferrule 31 of the optical fiber connector 3 will not contact the first baffle 221 and the second baffle 222, but the connector housing 32 of the optical fiber connector 3 contacts the first baffle 221 and the second baffle 222, and pushes the first baffle 221 and the second baffle 222 apart. In this way, it is not easy to cause dirt and damage to the optical fiber ferrule 31.

[0108] Furthermore, by arranging the first recessed portion 2211 and the second recessed portion 2221 forming the avoidance groove 220 on different baffles, the avoidance groove 220 will be split into two parts (the first recessed portion 2211 and the second recessed portion 2221) when the connector housing 32 pushes the first baffle 221 and the second baffle 222 open, and the optical fiber ferrule 31 will not be stuck in the avoidance groove 220. It is understandable that if the avoidance groove 220 is set on one baffle, since the avoidance groove 220 will not be split into two parts, the optical fiber ferrule 31 will be stuck in the avoidance groove 220, so that the connector housing 32 cannot push the baffle open.

[0109] In some examples, in order to allow the connector housing 32 to push the first baffle 221 and the second baffle 222 apart without the optical fiber ferrule 31 contacting the first baffle 221 and the second baffle 222, the depth of the avoidance groove 220 is set to be greater than the length of the optical fiber ferrule 31 extending relative to the connector housing 32.

[0110] Of course, in other examples, the depth of the avoidance groove 220 is less than or equal to the length of the optical fiber core 31 extending relative to the connector housing 32. In this case, a protruding structure needs to be provided on the first baffle 221 and the second baffle 222, and the protruding structure is used to interfere with the connector housing 32.

[0111] The embodiment of the present disclosure does not limit the form of the avoidance groove 220, and an exemplary description is given below. In some examples, such as Figure 10-12 As shown, the avoidance groove 220 includes a tapered portion 2201 , and along the depth direction of the avoidance groove 220 , the inner diameter of the tapered portion 2201 gradually decreases.

[0112] In this way, the inner diameter of the open end of the avoidance groove 220 is larger, so that the optical fiber ferrule 31 is not easy to accidentally touch the inner wall of the avoidance groove 220 when extending into the avoidance groove 220, thereby reducing the possibility of damage to the optical fiber ferrule 31 and reducing the requirements for the user's operating accuracy, thereby indirectly improving the operating efficiency.

[0113] In some examples, such as Fig.10 and Fig.11 As shown, the avoidance groove 220 further includes a cylindrical portion 2202 , and the cylindrical portion 2202 is communicated with the small diameter end of the conical portion 2201 .

[0114] In other examples, such as Fig.12 As shown, the inner diameter of the avoidance groove 220 gradually decreases along the depth direction. Alternatively, it can be understood that the avoidance groove 220 only includes the tapered portion 2201 .

[0115] In other examples, such as Fig.13 As shown, the avoidance groove 220 includes a cylindrical portion 2202 .

[0116] The embodiment of the present disclosure does not limit the number of channels 210 included in the dustproof component 2 and the number of baffle assemblies 22, and an exemplary description is given below.

[0117] In some examples, such as Figure 5 As shown, the optical port 111 of the optical module 1 includes an optical transmission port 111a and an optical receiving port 111b. Figure 5-Figure 7 As shown, the housing 21 has two channels 210, which are respectively used to communicate with the optical transmitting port 111a and the optical receiving port 111b of the optical module 1. The dustproof component 2 includes two baffle assemblies 22, which are respectively used to close the two channels 210.

[0118] The technical solution provided by the embodiment of the present disclosure is to provide a dustproof component 2 including two channels 210 and two baffle assemblies 22, so that the opening and closing of the two channels 210 are independent. In this way, during the process of plugging and unplugging the optical fiber connector 3 in the optical transmission port 111a, the dustproof of the optical receiving port 111b will not be affected. Similarly, during the process of plugging and unplugging the optical fiber connector 3 in the optical receiving port 111b, the dustproof of the optical transmission port 111a will not be affected. It can be seen that by adopting the above design, the dustproof effect of the dustproof component 2 is improved.

[0119] In some other examples, for the case where the optical module 1 has an optical transmitting port 111a and an optical receiving port 111b, as shown in FIG. Fig.14 As shown, the housing 21 has a channel 210. The channel 210 is used to communicate with both the optical transmission port 111a and the optical receiving port 111b of the optical module 1. The dustproof component 2 includes a baffle assembly 22.

[0120] The technical solution provided by the embodiment of the present disclosure reduces the number of baffle assemblies 22 included in the dustproof component 2 by setting a channel 210 to communicate with both the optical transmission port 111a and the optical receiving port 111b, which is conducive to reducing the cost of the dustproof component 2. In addition, generally speaking, the optical transmission port 111a and the optical receiving port 111b need to be used at the same time. Therefore, in most cases, there will not be a situation where one optical port 111 is inserted into the optical fiber connector 3 while the other optical port 111 is not inserted into the optical fiber connector 3. That is, in most cases, the optical port 111 will not be exposed.

[0121] In addition, for Fig.14In the dustproof component 2 shown, the first baffle 221 has two first recessed portions 2211, and the second baffle 222 has two second recessed portions 2221. When the first baffle 221 and the second baffle 222 close the channel 210, the two first recessed portions 2211 and the two second recessed portions 2221 form two avoidance grooves 220. The baffle assembly 22 is opposite to both the optical transmission port 111a and the optical receiving port 111b. The two avoidance grooves 220 are respectively opposite to the optical transmission port 111a and the optical receiving port 111b. The two avoidance grooves 200 are respectively used to accommodate the optical fiber ferrules 31 of the two optical fiber connectors 3.

[0122] In other examples, the optical port 111 of the optical module 1 is an optical bidirectional transmission port. Fig.15 As shown, the housing 21 has a channel 210, and the channel 210 is used to communicate with the optical bidirectional transmission port of the optical module 1. The dustproof component 2 includes a baffle assembly 22, and the baffle assembly 22 is used to close the channel 210.

[0123] The embodiment of the present disclosure does not limit the arrangement of the first baffle 221 and the second baffle 222. In some examples, such as Figure 6-Figure 7 and Figure 14-15 As shown, the first baffle 221 and the second baffle 222 are arranged up and down. The rotation axes of the first baffle 221 and the second baffle 222 are respectively located at the upper and lower sides of the channel 210.

[0124] In other examples, such as Fig.16 As shown, the first baffle 221 and the second baffle 222 are arranged left and right. The rotation axes of the first baffle 221 and the second baffle 222 are located at the left and right sides of the channel 210, respectively.

[0125] The embodiment of the present disclosure does not limit the manner in which the first baffle 221 and the second baffle 222 close the channel 210 after the optical fiber connector 3 is pulled out from the channel 210. An exemplary description is given below.

[0126] In some examples, such as Fig.17 As shown, the dustproof component 2 further includes a first elastic member 23 and a second elastic member 24. The first elastic member 23 and the second elastic member 24 are used to drive the first baffle 221 and the second baffle 222 to close the channel 210.

[0127] In this way, during the process of pulling out the optical fiber connector 3, under the elastic force of the first elastic member 23 and the second elastic member 24, the first baffle 221 and the second baffle 222 gradually rotate toward the outside of the channel 210, so that the first baffle 221 and the second baffle 222 can close the channel 210 in time, thereby improving the dustproof effect of the dustproof component 2. In addition, the user does not need to manually operate the first baffle 221 and the second baffle 222 to close the channel 210 after pulling out the optical fiber connector 3, further simplifying the user's operation.

[0128] It should be noted that, due to the existence of the first elastic member 23 and the second elastic member 24 , when the optical fiber connector 3 is inserted into the channel 210 , the elastic force of the first elastic member 23 and the second elastic member 24 needs to be overcome.

[0129] In other examples, the dustproof component 2 includes a magnetic attraction component, which is arranged on the first baffle 221, the second baffle 222 and the housing 21. The magnetic attraction component is used to make the first baffle 221 and the second baffle 222 adsorb on the housing 21 when they are in a closed state. In particular, due to the presence of the magnetic attraction component, when the optical fiber connector 3 is inserted into the channel 210, the magnetic attraction force of the magnetic attraction component needs to be overcome.

[0130] In addition, for the technical solution that the dustproof component 2 includes a magnetic suction component, when the optical fiber connector 3 is pulled out, in some examples, the magnetic suction component is used to adsorb the first baffle 221 and the second baffle 222, and the first baffle 221 and the second baffle 222 automatically close the channel 210. In this way, the user does not need to manually operate the first baffle 221 and the second baffle 222 to close the channel 210, which simplifies the user's operation. In other examples, after the optical fiber connector 3 is pulled out, the user manually operates the first baffle 221 and the second baffle 222 to close the channel 210, and under the action of the magnetic suction component, the first baffle 221 and the second baffle 222 remain in a closed state.

[0131] The disclosed embodiment does not limit the types of the first elastic member 23 and the second elastic member 24. For example, the first elastic member 23 and the second elastic member 24 are torsion springs, compression springs, or spring sheets, etc. Below, taking the first elastic member 23 and the second elastic member 24 as torsion springs as an example, the configuration of the first elastic member 23 and the second elastic member 24 is described as an example.

[0132] like Fig.17 As shown, the first baffle 221 is rotatably connected to the housing 21 via the first mounting shaft 2210, the first elastic member 23 is sleeved around the first mounting shaft 2210, and the two torsion arms are respectively against the first baffle 221 and the housing 21. The second baffle 222 is rotatably connected to the housing 21 via the second mounting shaft 2220, the second elastic member 24 is sleeved around the second mounting shaft 2220, and the two torsion arms are respectively against the second baffle 222 and the housing 21.

[0133] When the optical fiber connector 3 pushes the first baffle 221 and the second baffle 222 to rotate, the first baffle 221 and the second baffle 222 drive the corresponding torsion arms to twist, and the torsion spring accumulates force. When the optical fiber connector 3 is pulled out of the channel 210, the torsion spring releases its elastic force, and drives the first baffle 221 and the second baffle 222 to rotate toward the outside of the channel 210 through the torsion arm, and gradually closes the channel 210. Afterwards, under the elastic force of the torsion spring, the first baffle 221 and the second baffle 222 are stabilized in a closed state.

[0134] In some examples, such as Fig.17 As shown, the first installation shaft 2210 and the second installation shaft 2220 are fixed to the first baffle plate 221 and the second baffle plate 222 , and the first installation shaft 2210 and the second installation shaft 2220 are rotation shafts and are rotationally connected to the housing 21 .

[0135] In other examples, the first installation shaft 2210 and the second installation shaft 2220 are fixed shafts and are both fixed to the housing 21. The first baffle plate 221 and the second baffle plate 222 are provided with circular holes, and are respectively encircled by the first installation shaft 2210 and the second installation shaft 2220, so that the first baffle plate 221 and the second baffle plate 222 can rotate around the first installation shaft 2210 and the second installation shaft 2220 respectively.

[0136] The disclosed embodiment does not limit the type of the optical port 111 of the optical module 1. Exemplarily, the type of the optical port 111 of the optical module 1 is a Lucent connector (lucent connector / local connector, LC) type, a ferrule connector (ferrule connector, FC) type, a subscriber connector / standard connector / square connector (subscriber connector / standard connector / square connector, SC) type, or a straight tip (straight tip, ST) type, etc.

[0137] For the case where the optical port 111 of the optical module 1 is of LC type, such as Figure 8 and Fig. 9 As shown, the optical fiber connector 3 connected to the optical module 1 also has a locking mechanism 33. The locking mechanism 33 is used to lock the optical fiber connector 3 on the optical module 1. In addition, when the optical fiber connector 3 needs to be pulled out, the locking mechanism 33 needs to be pressed first.

[0138] In some examples, in order to enable the locking mechanism 33 to be pressed after the optical fiber connector 3 is plugged into place, and not to be blocked by the housing 21, such as Fig.18As shown, the housing 21 is provided with an opening 215. The opening 215 enables the locking mechanism 33 to be exposed, so that the user can press the locking mechanism 33. However, when the dustproof component 2 is not inserted into the optical fiber connector 3, dust can easily enter the optical port 111 through the opening 215.

[0139] In some examples, in order to prevent dust from entering the optical port 111 of the optical module 1 through the opening 215, as shown in FIG. Fig.18 As shown, the dustproof component 2 further includes a pressing block 25, and the pressing block 25 is movably connected to the housing 21. Figure 8 and Fig. 9 As shown, after the optical fiber connector 3 is inserted into the channel 210 , the locking mechanism 33 of the optical fiber connector 3 is located on the movable path of the pressing block 25 , and the pressing block 25 is configured to press the locking mechanism 33 .

[0140] The technical solution provided by the embodiment of the present disclosure is to set the pressing block 25. Firstly, when the optical fiber connector 3 needs to be pulled out, the user can press the locking structure 33 by operating the pressing block 25 to release the locking state of the locking mechanism 33, so that the optical fiber connector 3 can be pulled out smoothly. Secondly, the pressing block 25 can close the opening 215 where it is located, so that dust will not enter the optical port 111 through the opening 215.

[0141] In some examples, such as Figure 8 and Fig. 9 As shown, the pressing block 25 is located on the insertion path of the locking mechanism 33 of the optical fiber connector 3 , and the pressing block 25 is also configured to be lifted up by the locking mechanism 33 during the process of inserting the optical fiber connector 3 into the channel 210 .

[0142] The embodiment of the present disclosure does not limit the connection method between the pressing block 25 and the housing 21. In some examples, such as Fig.18 As shown, the pressing block 25 is rotatably connected to the housing 21 .

[0143] In some examples, such as Fig.18 and Fig.19 As shown, the pressing block 25 is rotatably connected to the housing 21 via a third mounting shaft 251 .

[0144] In some examples, the third installation shaft 251 is fixed to the pressing block 25 , and the third installation shaft 251 is a rotating shaft.

[0145] In other examples, the third installation shaft 251 is fixed to the housing 21 , and the pressing block 25 is provided with a circular hole, which surrounds the third installation shaft 251 , and the pressing block 25 can rotate around the third installation shaft 251 .

[0146] In some examples, such as Fig.18As shown, the position of the rotational connection (such as the third mounting axis 251 ) is located at a corner position of the pressing block 25 , which is one of the four corner positions, close to the outside of the shell 21 and away from the baffle assembly 22 .

[0147] In some examples, such as Fig.18 and Fig.19 As shown, the pressing block 25 has a recessed portion 252. Figure 8 and Fig. 9 As shown, the recessed portion 252 matches the raised portion of the locking mechanism 33 to press the locking mechanism 33 .

[0148] In some examples, such as Fig.18 and Fig.19 As shown, the pressing block 25 has a curved surface 253 , and the curved surface 253 is used to prevent the pressing block 25 from interfering with the hole wall of the opening 215 .

[0149] In some examples, the pressing block 25 is slidably connected to the housing 21. For example, the pressing block 25 is slidably connected along the up-down direction or approximately the up-down direction.

[0150] The embodiment of the present disclosure does not limit the number of the pressing blocks 25. In some examples, for example, Fig.18 As shown, there are two pressing blocks 25 , and the two pressing blocks 25 are used to press the locking mechanisms 33 of the two optical fiber connectors 3 respectively.

[0151] In other examples, such as Fig. 20 As shown, there is only one pressing block 25, which is used to simultaneously press the locking mechanisms 33 of two optical fiber connectors 3. Of course, if the optical port 111 of the optical module 1 is a bidirectional optical transmission port, the pressing block 25 is used to press the locking mechanism 33 of one optical fiber connector 3.

[0152] The embodiments of the present disclosure do not limit the connection method between the dustproof component 2 and the optical module 1. In some examples, the dustproof component 2 is integrally connected to the optical module 1, that is, the shell of the optical module 1 and the shell 21 of the dustproof component 2 are integrally formed, and the optical module 1 comes with the dustproof component 2 when leaving the factory.

[0153] In other examples, the dustproof component 2 is detachably connected to the optical module 1, for example, by clamping, welding, riveting, screwing, etc. Below, the clamping of the dustproof component 2 and the optical module 1 is taken as an example to exemplify the connection method of the dustproof component 2 and the optical module 1.

[0154] In some examples, such as Fig.21 and Fig. 22 As shown, the housing 21 further has two snap-in strips 214 , and the two snap-in strips 214 are used to snap-in into the grooves 112 of the two side walls of the optical module 1 .

[0155] In some examples, such as Fig. 22 and Fig.23 As shown, the optical module 1 includes an optical module body 11 and a handle bar 12. The two side walls of the optical module body 11 have grooves 112, and the groove 112 has an opening at the end of the optical module body 11. When the handle bar 12 is in a locked state, the handle bar 12 closes the opening of the groove 112. When the handle bar 12 is in an unlocked state, there is a gap 10 between the handle bar 12 and the end of the optical module body 11, and the groove 112 is connected to the gap 10 through the opening. The snap-in strip 214 is used to enter and exit the groove 112 through the gap 10. Among them, the handle bar 12 is used to lock the optical module 1 on the communication device.

[0156] like Fig.23 As shown, the dustproof component 2 is installed on the optical module 1 in the following installation manner.

[0157] In the first step, the handle bar 12 is pulled open so that a gap 10 is formed between the handle bar 12 and the end of the optical module body 11 .

[0158] In the second step, the clamping strip 214 of the dustproof component 2 is aligned with the gap 10 , and the clamping strip 214 is inserted into the gap 10 .

[0159] The third step is to slide the dustproof component 2 so that the clamping strip 214 slides into the groove 112 .

[0160] The fourth step is to tighten the handle bar 12 so that the handle bar 12 closes the opening of the groove 112, and the clamping strip 214 of the dustproof component 2 is restricted in the groove 112, and the installation of the dustproof component 2 is completed.

[0161] The technical solution provided by the embodiment of the present disclosure utilizes the existing groove 112 on the optical module 1, and utilizes the fact that when the handle bar 12 is in a locked state, the handle bar 12 closes the opening of the groove 112, and when the handle bar 12 is in an unlocked state, there is a gap 10 between the handle bar 12 and the end of the optical module body 11, so that the clamping strip 214 of the dustproof component 2 can pass through the gap 10 to enter and exit the groove 112, thereby realizing the non-destructive disassembly and assembly of the dustproof component 2. During multiple disassembly and assembly processes, the support arm 213 (such as Fig.21 shown) will not be pulled apart.

[0162] Furthermore, the above connection method does not require improvement of the structure of the optical module 1, so that the dustproof component 2 can be compatible with the existing optical module 1, which greatly reduces the application cost of the dustproof component 2. Of course, for some optical modules 1 that do not have the groove 112, the groove 112 can be opened on the side wall of the optical module 1, and then the above connection method is used to connect the dustproof component 2 to the optical module 1.

[0163] In some examples, such as Fig.21As shown, the housing 21 includes a main body 211, two connecting parts 212, two support arms 213 and two clamping strips 214. The main body 211 has a channel 210. The two support arms 213 are connected to both sides of the main body 211 through the two connecting parts 212. The two clamping strips 214 are respectively located on the inner sides of the two support arms 213.

[0164] In some examples, such as Fig.21 and Fig. 22 As shown, the width L1 of the main body 211 is smaller than the distance L2 between the two inner side walls of the handle bar 12 , so that the main body 211 can extend between the two inner side walls of the handle bar 12 .

[0165] In some examples, such as Fig.21 and Fig. 22 As shown, the distance L3 between the two support arms 213 is greater than the distance L4 between the two side walls of the optical module body 11 , so that the two support arms 213 can be buckled on the optical module body 11 .

[0166] In some examples, such as Fig.21 and Fig. 22 As shown, the distance L3 between the two support arms is greater than the distance L5 between the two outer side walls of the handle strip 12 .

[0167] In some examples, such as Fig.21 and Fig. 22 As shown, the distance L6 between the two clamping strips 214 is smaller than the distance L4 between the two outer side walls of the optical module body 11 , so that the two clamping strips 214 can be clamped in the grooves 112 of the two outer side walls of the optical module body 11 .

[0168] In some examples, such as Fig.21 and Fig. 22 As shown, the length L7 of the clamping strip 214 is smaller than the width L8 of the gap 10 , so that the clamping strip 214 can enter into the gap 10 .

[0169] In addition, the dustproof component 2 provided in the embodiment of the present disclosure can also support active cleaning of the optical port 111 of the optical module 1. During cleaning, after the cleaning rod pushes open the first baffle 221 and the second baffle 222, the optical port 111 can be cleaned.

[0170] The present disclosure also provides another dust-proof component 2. Fig.21 As shown, the dustproof component 2 includes a housing 21 and at least one baffle assembly 22. The housing 21 has at least one channel 210 and two snap-in strips 214. The channel 210 is used to communicate with the optical port 111 of the optical module 1, and the baffle assembly 22 is used to close the channel 210. The two snap-in strips 214 are used to snap-in with the grooves 112 on both sides of the optical module 1.

[0171] The baffle assembly 22 is not limited to the implementation of the first baffle 221 and the second baffle 222, and other implementations can be adopted. For example, the baffle assembly 22 includes only one baffle, and the baffle alone closes one channel 210. The baffle is also not limited to opening the channel 210 by rotating toward the inside of the channel 210. For example, Figure 2 As shown, the baffle can open the channel 210 by rotating toward the outside of the channel 210.

[0172] The technical solution provided by the embodiment of the present disclosure, by providing a baffle assembly 22 to close the channel 210, enables the dustproof component 2 to close the optical port 111 of the optical module 1, thereby realizing the dustproof function of the optical module 1. In addition, by providing the housing 21 with two snap-on strips 214, the dustproof component 2 can be snap-on to the optical module 1, thereby reducing the possibility of the dustproof component 2 being lost.

[0173] In some examples, such as Fig. 22 and Fig.23 As shown, the optical module 1 includes an optical module body 11 and a handle bar 12. The two side walls of the optical module body 11 have grooves 112, and the groove 112 has an opening at the end of the optical module body 11. When the handle bar 12 is in a locked state, the handle bar 12 closes the opening of the groove 112. When the handle bar 12 is in an unlocked state, there is a gap 10 between the handle bar 12 and the end of the optical module body 11, and the groove 112 is connected to the gap 10 through the opening. The snap-in strip 214 is used to enter and exit the groove 112 through the gap 10. Among them, the length L4 of the snap-in strip 214 is less than the width L5 of the gap 10.

[0174] like Fig.23 As shown, the dustproof component 2 is installed on the optical module 1 in the following installation manner.

[0175] In the first step, the handle bar 12 is pulled open so that a gap 10 is formed between the handle bar 12 and the end of the optical module body 11 .

[0176] In the second step, the clamping strip 214 of the dustproof component 2 is aligned with the gap 10 , and the clamping strip 214 is inserted into the gap 10 .

[0177] The third step is to slide the dustproof component 2 so that the clamping strip 214 slides into the groove 112 .

[0178] The fourth step is to tighten the handle bar 12 so that the handle bar 12 closes the opening of the groove 112, and the clamping strip 214 of the dustproof component 2 is restricted in the groove 112, and the installation of the dustproof component 2 is completed.

[0179] The technical solution provided by the embodiment of the present disclosure utilizes the existing groove 112 on the optical module 1, and utilizes the fact that when the handle bar 12 is in a locked state, the handle bar 12 closes the opening of the groove 112, and when the handle bar 12 is in an unlocked state, there is a gap 10 between the handle bar 12 and the end of the optical module body 11, so that the clamping strip 214 of the dustproof component 2 can pass through the gap 10 to enter and exit the groove 112, thereby realizing the non-destructive disassembly and assembly of the dustproof component 2. During multiple disassembly and assembly processes, the support arm 213 will not be broken.

[0180] Furthermore, the above connection method does not require improvement of the structure of the optical module 1, so that the dustproof component 2 can be compatible with the existing optical module 1, which greatly reduces the application cost of the dustproof component 2. Of course, for some optical modules 1 that do not have the groove 112, the groove 112 can be opened on the side wall of the optical module 1, and then the above connection method is used to connect the dustproof component 2 to the optical module 1.
