Description

The optoelectronic component and the circuit board component are electrically connected to each other for mutual conversion of optoelectronic signals. The optoelectronic component has an optical end face. If each optical end face is contaminated by dirt such as dust and water vapor, it will affect the transmission of the optical signal, thereby causing the optical module to malfunction. In order to prevent external dust and other dirt from entering the optical module, various dustproof seals are usually set at the optical interface of the optical module to prevent dust from entering the optical interface of the optical module and contaminating the optical end face.
[0003] However, even if the optical module with MPO (Multi-fiber Push On) port is dust-proof, in actual use, the optical end face inside the optical module is still dirty, resulting in optical module failure.
[0004] When the MPO optical module is used, it is connected to the optical fiber of the MPO connector. According to the IEC protocol requirements, the MPO connector on the optical fiber is provided with a sliding sleeve and a sliding table. The sliding groove on the sliding sleeve slides with the protrusion on the sliding table to achieve relative movement between the sliding sleeve and the sliding table, thereby pulling the MPO connector of the optical fiber out of the optical module.
[0005] However, since there is a gap between the sliding groove on the sliding sleeve and the protrusion on the sliding table, the gap may cause dirt such as dust to enter the sliding sleeve from the outside, and then enter the optical module to contaminate the optical end face of the optical module, causing module failure.

[0033] Please refer to Figure 1-Figure 4 , Figure 1 This is a schematic diagram of an MPO port optical module in an embodiment of the present application; Figure 2 This is a schematic structural diagram of the MPO connector of the optical fiber in the embodiment of the present application from the first perspective; Figure 3 This is a schematic structural diagram of the MPO connector of the optical fiber in the embodiment of the present application from a second viewing angle; Figure 4 Schematic diagram of the structure of the MPO interface of the optical module in the embodiment of the present application.
[0034] An embodiment of the present application provides an optical fiber 100, which includes an optical fiber body 110, a slide 120, a sliding sleeve 130 and an elastic seal 140. The slide 120 has a first end 126 and a second end 127 opposite to each other. The first end 126 is used to dock with an external MPO interface 210, and the second end 127 is connected to the optical fiber body 110. A protrusion 121 is provided on the slide 120, and the protrusion 121 extends from the first end 126 to the second end 127. A sliding groove 131 is provided on the sliding sleeve 130. The sliding groove 131 and the protrusion 121 are slidably matched to enable the sliding sleeve 130 to slide between the first end 126 and the second end 127. There is a gap between the protrusion 121 and the slide groove 131, and the elastic seal 140 seals at least one side of the gap adjacent to the second end 127.
[0035] In this embodiment, the optical fiber body 110 is a cable with multiple optical fibers, the second end 127 of the slide 120 is connected to one end of the optical fiber body 110, and the protrusion 121 on the slide 120 is slidably matched with the slide groove 131 on the sliding sleeve 130. The optical fiber 100 also includes a ferrule 150, and the fiber cores of the ends of each optical fiber of the optical fiber body 110 are inserted into the ferrule 150 and arranged side by side in the ferrule 150. The ferrule 150 then passes through the slide 120 from the second end 127 of the slide 120 and protrudes out of the first end 126 of the slide 120. Two pins or sockets are set at the end of the ferrule 150, which are used to cooperate with two sockets or pins in the MPO interface 210 of the MPO port optical module 10, play a guiding and positioning role, so that the fiber cores side by side on the end face of the ferrule are respectively aligned with the fiber cores on the optical end face of the MPO interface.
[0036] In other embodiments, the protrusion 121 is disposed in the sliding sleeve 130 , and the sliding groove 131 is opened on the slide 120 . The protrusion 121 and the sliding groove 131 are slidably matched, so that the slide 120 and the sliding sleeve 130 can slide relative to each other.
[0037] When in use, the first end 126 of the slide 120 is used to be inserted into the external MPO interface so that the end face of the ferrule 150 is aligned with the optical end face of the MPO interface. At this time, the gap between the protrusion 121 and the slide groove 131 on the side adjacent to the first end 126 is located in the external MPO interface, so the elastic seal 140 seals the side of the gap adjacent to the second end 127, so that external dirt cannot enter the MPO interface 210 and the components connected to the rear end of the MPO interface 210 through the gap, and the elastic seal 140 does not affect the sliding fit between the protrusion 121 and the slide groove 131.
[0038] In this embodiment, the protrusion 121 is disposed on the outer wall of the slide 120 , and a first gap is defined between the outer wall of the slide 120 and the inner wall of the sliding sleeve 130 . The elastic seal 140 simultaneously seals the gap and the side of the first gap adjacent to the second end 127 .
[0039] It should be noted that the gap is located between the protrusion 121 and the slide groove 131, the first gap is located between the outer wall of the slide table 120 excluding the protrusion 121 and the inner wall of the sliding sleeve 130, and the elastic seal 140 is arranged circumferentially around the slide table 120 to seal the gap and the first gap at the same time to prevent external dust and other dirt from entering from the side of the sliding sleeve 130 near the second end 127 of the slide table 120.
[0040] In this embodiment, the sliding sleeve 130 has a first opening end 132 and a second opening end 133 opposite to each other, and the first end 126 and the second end 127 of the sliding table 120 extend out of the sliding sleeve 130 at the first opening end 132 and the second opening end 133 respectively, and the elastic sealing member 140 seals the gap and the first gap at the second opening end 133.
[0041] It should be pointed out that when connecting the optical fiber 100 and the MPO interface 210, the sliding sleeve 130 and the slide 120 are partially inserted into the MPO interface 210, so that the end face of the core 150 extending out of the first end 126 of the slide 120 cooperates with the internal optical end face of the MPO interface 210, and the side of the slide 120 is snap-fitted with the MPO interface 210 to insert the slide 120 into the MPO interface 210, and light transmission can be performed at this time.
[0042] In this embodiment, the protrusion 121 is a slide rail extending between the first end 126 and the second end 127, and its cross-section is roughly rectangular. Correspondingly, the opening of the slide groove 131 is rectangular. When the sliding sleeve 130 and the slide table 120 slide relative to each other, the protrusion 121 slides relative to each other in the slide groove 131.
[0043] Of course, it is understandable that in other embodiments, the cross-section of the protrusion 121 can also be other shapes, such as circular, semicircular or other arc sectors, polygons, etc., and the opening of the slide groove 131 can be circular, arc-shaped or polygonal, etc. to match it, as long as the protrusion 121 can slide in the slide groove 131.
[0044] In this embodiment, a boss 124 is provided at the second end 127 of the slide 120, a receiving groove 125 is formed between the boss 124 and the sliding sleeve 130, and an elastic seal 140 is filled in the receiving groove 125. By filling the elastic seal 140 in the receiving groove 125 formed between the boss 124 and the sliding sleeve 130, on the one hand, the elastic seal 140 is fixed, and on the other hand, the elastic seal 140 can seal the gap and the first gap on the side adjacent to the second end 127 of the slide 120.
[0045] In this embodiment, the elastic sealing member 140 is a flexible sealant or a sticky foam.
[0046] It should be noted that the flexible sealant or the sticky foam is made of a material with good stickiness, softness and reliability, which can play a sealing role without affecting the relative sliding between the sliding sleeve 130 and the sliding table 120 .
[0047] Among them, flexible sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain adhesion, so it can fill gaps and clearances and play a sealing role. At the same time, some sealants can also prevent leakage, waterproof, anti-vibration, sound insulation, heat insulation and other functions.
[0048] Exemplarily, the flexible sealant is silicone rubber, and more preferably conductive rubber can be used. The conductive rubber is made by evenly distributing conductive particles such as silver-plated glass, silver-plated aluminum, and silver in the silicone rubber, and the conductive particles are brought into contact through pressure to achieve good conductive properties. In addition, the conductive rubber has good electromagnetic sealing and water vapor sealing capabilities, and therefore, can be used to seal the gap and the first gap between the sliding sleeve 130 and the sliding table 120.
[0049] The sticky foam can be made of EVA plastic or resin. The characteristics of EVA plastic or resin are good softness and rubber-like elasticity. They can still have good flexibility at -50 degrees Celsius, good transparency and surface gloss, good chemical stability, good aging resistance and ozone resistance, and are non-toxic. They have good miscibility with fillers and good coloring and molding processability. They mainly play the roles of anti-slip, shockproof, fixing, dustproof, and sealing. Therefore, they can also be used to seal the gap and the first gap between the sliding sleeve 130 and the sliding table 120.
[0050] The thickness of the EVA foam material is generally 0.3 mm-70 mm. For example, the thickness of the EVA foam material is 0.3 mm, 1 mm, 2 mm, etc. In this embodiment, the thickness of the EVA foam can be selected according to actual working conditions.
[0051] Of course, in other embodiments, the elastic sealing member 140 may also be a sealing member other than the flexible sealant or the sticky foam, as long as it can perform the sealing function without affecting the relative sliding between the sliding sleeve 130 and the sliding table 120 .
[0052] The embodiment of the present application also provides an MPO port optical module 10, including the above-mentioned optical fiber 100 and a module body 200, wherein the module body 200 has an MPO interface 210, wherein the sliding sleeve 130 and the sliding table 120 partially extend into the MPO interface 210, and the sliding table 120 and the MPO interface 210 are engaged with each other, so that the optical fiber body 110 is optically connected to the optical fiber in the MPO interface 210; a dustproof rubber ring 134 is provided on the sliding sleeve 130 at one side plugged with the MPO interface 210, and the dustproof rubber ring 134 is sealed between the sliding sleeve 130 and the MPO interface 210 when the sliding table 120 is plugged into the MPO interface 210. The module body 200 includes a housing, an optoelectronic component and a circuit board component, wherein the optoelectronic component and the circuit board component are electrically connected and arranged in the housing, and the MPO interface 210 is arranged at one end of the housing. When the optical fiber 100 of the above embodiment is plugged into the MPO interface 210 of the module body 200, it can effectively prevent external dust and other dirt from entering the shell through the gap or clearance between the slide 120 and the sliding sleeve 130 of the optical fiber 100, thereby avoiding contamination of the optoelectronic components in the shell.
[0053] It should be noted that grooves 135 are provided on two opposite surfaces of the sliding sleeve 130, and the dustproof rubber ring 134 is sleeved and clamped in the two grooves 135. When the side of the slide 120 is clamped and matched with the MPO interface 210, the dustproof rubber ring 134 can seal the MPO interface 210. One of the slide 120 and the MPO interface 210 is provided with a hook 220, and the other of the slide 120 and the MPO interface 210 is provided with a slot 122. The hook 220 is clamped and matched with the slot 122 to insert and fix the slide 120 and the sliding sleeve 130 into the MPO interface 210.
[0054] In other embodiments, snap hooks are respectively provided on the slide 120 and the MPO interface 210 , and the snap hooks on the slide 120 and the MPO interface 210 are engaged with each other to achieve the connection between the slide 120 and the MPO interface 210 .
[0055] In this embodiment, the hook 220 is arranged on the MPO interface 210, the slot 122 is arranged on the slide 120, and a guide groove 123 is also arranged on the slide 120. The slot 122 and the guide groove 123 are arranged along the sliding direction of the sliding sleeve 130. The hook 220 is used to engage with the slot 122 after being guided by the guide groove 123.
[0056] It should be pointed out that the hook 220 is arranged inside the MPO interface 210 and has a certain elasticity. The slot 122 and the guide slot 123 are both arranged on the side of the slide 120. The slot 122 and the guide slot 123 are arranged in sequence along the sliding direction of the sliding sleeve 130. The slot 122 is closer to the second end 127 of the slide 120 relative to the guide slot 123. When the slide 120 extends into the MPO interface 210, the hook 220 is guided by the guide slot 123 and then engages with the slot 122.
[0057] In order to ensure that the hook 220 and the slot 122 cooperate stably, the sliding sleeve 130 is slid toward one side of the MPO interface 210 until the sliding sleeve 130 completely covers the slot 122, and the hook 220 is locked in the slot 122. At this time, the hook 220 is not easy to be disengaged from the slot 122, and the stability of the cooperation between the hook 220 and the slot 122 is improved; and when the optical fiber 100 needs to be pulled out of the MPO interface 210, the sliding sleeve 130 is slid toward one side of the second end 127 of the slide 120 until the sliding sleeve 130 no longer covers the hook 220, and the sliding sleeve 130 continues to apply force to the optical fiber 100 toward the side away from the MPO interface 210, so that the hook 220 can be disengaged from the slot 122, thereby pulling out the optical fiber from the MPO interface 210.
[0058] Furthermore, two inner side walls of the clamping slot 122 and the guide slot 123 that are opposite to each other are both inclined.
[0059] It should be pointed out that the two inner side walls opposite to the card slot 122 and the guide slot 123 are both inclined surfaces, and the distance between the bottom ends of the two inclined surfaces is greater than the distance between the top ends of the two inclined surfaces, so that the hook 220 can move smoothly from the guide slot 123 to the card slot 122 and from the card slot 122 to the guide slot 123, thereby playing a guiding role.
[0060] In summary, the embodiment of the present application provides an optical fiber 100 and an MPO port optical module 10. In order to prevent external dirt from entering through the gap between the sliding sleeve 130 and the sliding table 120 and the first gap, a circle of flexible sealant or sticky foam is arranged around the sliding table 120. Since the flexible sealant or sticky foam has good viscosity, softness and reliability, it will not affect the relative sliding between the sliding sleeve 130 and the sliding table 120 while playing a sealing role. When the optical fiber 100 is connected to the MPO interface 210, the hook 220 in the MPO interface 210 is engaged with the slot 122 on the slide 120, and the sliding sleeve 130 is slid to cover the slot 122 to prevent the hook 220 from being separated from the slot 122; when the optical fiber 100 needs to be separated from the MPO interface 210, the sliding sleeve 130 is slid until it no longer covers the slot 122, exposing the hook 220. At this time, the optical fiber 100 is pulled out, and the hook 220 can be separated from the slot 122.
[0061] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
