[0001] The present disclosure relates to the field of optical technology, and in particular to an optical fiber adapter, an optical fiber connection assembly, an optical fiber ferrule cleaner and an optical device. Background Art

[0002] Fiber optic connectors and fiber optic adapters are devices that make detachable connections between optical fibers. Two fiber optic connectors are connected to the butt ends of two optical fibers, and a fiber optic adapter butts the fiber optic ferrules of two fiber optic connectors.

[0003] In practical applications, dirt may be introduced into the end face of the optical fiber ferrule, which will affect the reliability of the optical transmission system. Summary of the invention

[0004] The present disclosure provides a fiber optic adapter, a fiber optic connection assembly, a fiber optic ferrule cleaner, and an optical device. The fiber optic adapter includes a housing and a discharge assembly, and the discharge assembly can discharge in the housing to clean the end face of the fiber optic ferrule. The technical solutions of the fiber optic adapter, the fiber optic connection assembly, the fiber optic ferrule cleaner, and the optical device are as follows:

[0005] In a first aspect, the present disclosure provides a fiber optic adapter. The fiber optic adapter includes a housing and a discharge assembly. Both ends of the housing have interfaces for docking fiber optic connectors, and the housing is used to dock the fiber optic ferrules of two fiber optic connectors. The discharge assembly is fixed to the housing, and the discharge assembly is used to discharge inside the housing.

[0006] The optical fiber adapter can also be called an optical fiber flange. The optical fiber adapter can be a lucent connector / local connector (LC) type optical fiber adapter, a ferrule connector (FC) type optical fiber adapter, a subscriber connector / standard connector / square connector (SC) type optical fiber adapter, a straight tip (ST) type optical fiber adapter, a miniature unit coupling (MU) type optical fiber adapter, a mechanical transfer (MT) type optical fiber adapter, a DIN type optical fiber adapter, a D4 type optical fiber adapter, etc.

[0007] The optical fiber ferrule includes a ferrule and an optical fiber. A fixing hole is provided at the center of the ferrule, and the optical fiber is located in the fixing hole. The ferrule may be a ceramic ferrule, but is not limited thereto.

[0008] The technical solution provided by the present disclosure is to set a discharge component in the shell of the optical fiber adapter to discharge electricity, so that during the process of docking the optical fiber adapter with the optical fiber connector, the discharge of the discharge component can be triggered to clean the end face of the optical fiber ferrule of the optical fiber connector, thereby improving the cleanliness of the end face of the optical fiber ferrule and improving the reliability of the optical transmission system.

[0009] In a possible implementation, the discharge voltage of the discharge assembly is greater than 1 kV, so that the cleaning effect on the end face of the optical fiber ferrule can be guaranteed.

[0010] In a possible implementation, the discharge voltage of the discharge component is less than 12 kV to prevent the electricity discharged by the discharge component from damaging the optical fiber ferrule.

[0011] In a possible implementation, the discharge voltage of the discharge assembly is less than 5 kV to further reduce the possibility of damage to the optical fiber ferrule.

[0012] In a possible implementation, the discharge assembly includes a power supply, a first electrode, and a second electrode. The power supply is electrically connected to the first electrode and the second electrode. The first electrode and the second electrode are located inside the housing and face each other, and the first electrode and the second electrode are used for discharge.

[0013] The opposite ends of the first electrode and the second electrode are sharp. When the power source supplies power to the first electrode and the second electrode, the first electrode and the second electrode generate instantaneous high voltage and break through the air between the first electrode and the second electrode, so that an arc is generated between the first electrode and the second electrode, and the arc can clean the end face of the optical fiber ferrule.

[0014] In a possible implementation manner, the first electrode and the second electrode are needle-shaped electrodes, thereby improving the discharge effect of the first electrode and the second electrode.

[0015] In a possible implementation, the first electrode and the second electrode are coaxially arranged, and the line between the first electrode and the second electrode intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule. In this way, the arc generated between the first electrode and the second electrode can pass through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0016] In a possible implementation, the discharge assembly further includes a wire, through which the power source is electrically connected to the first electrode and the second electrode, and the wire is embedded in the shell wall.

[0017] In a possible implementation, the connection line of the first electrode and the second electrode passes through the butt joint of the two optical fiber ferrules. In this way, the end faces of the two optical fiber ferrules can be cleaned by a set of the first electrode and the second electrode, which reduces the number of components required for the optical fiber adapter and reduces the cost of the optical fiber adapter.

[0018] In one possible implementation, there are two discharge assemblies, and the electrode pairs of the two discharge assemblies are respectively located on both sides of the docking position of the two optical fiber ferrules, and the two electrode pairs are respectively used to clean the end faces of the two optical fiber ferrules, wherein the electrode pairs include a first electrode and a second electrode.

[0019] In a possible implementation, the discharge component is used to discharge before the optical fiber ferrule reaches the docking position.

[0020] The technical solution provided by the present disclosure is that since the optical fiber adapter needs to be docked with two optical fiber connectors, and when the optical fiber ferrules of the two optical fiber connectors reach the docking position, the end faces of the two optical fiber ferrules will be in close contact, and if discharge is performed at this time, it will not be able to clean the end faces of the optical fiber ferrules. Therefore, by setting a discharge component to discharge before the optical fiber ferrules reach the docking position, the end faces of the optical fiber ferrules can be cleaned.

[0021] In a possible implementation, the optical fiber adapter further includes a sleeve. The sleeve is located inside the housing and is used to accommodate the optical fiber ferrule. The first electrode and the second electrode are located on both sides of the sleeve and are used to discharge inside the sleeve. The sleeve is used to accommodate the optical fiber ferrules of two optical fiber connectors. By discharging the first electrode and the second electrode inside the sleeve, the end face of the optical fiber ferrule can be cleaned.

[0022] In a possible implementation, the line between the first electrode and the second electrode is perpendicular to the central axis of the sleeve. The sleeve and the optical fiber ferrule share the same central axis. In this way, the arc generated between the first electrode and the second electrode can pass through the center of the end face of the optical fiber ferrule, that is, through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0023] In a possible implementation, the wall of the sleeve is provided with a first opening and a second opening opposite to each other. The first electrode extends into the first opening, and the second electrode extends into the second opening. In this way, when the first electrode and the second electrode discharge, the air between the first electrode and the second electrode is broken through. The first opening and the second opening are connected to the interior of the sleeve.

[0024] In a possible implementation, the first electrode and the second electrode are contracted relative to the inner wall of the sleeve, so that the first electrode and the second electrode can be prevented from interfering with the optical fiber connector and being damaged by the optical fiber connector.

[0025] In a possible implementation, the optical fiber adapter further includes a connector, and the sleeve is connected to the housing through the connector. The first electrode and the second electrode are fixed inside the connector. At least a portion of the first electrode and the second electrode are fixed inside the connector, and other portions of the first electrode and the second electrode may also be fixed in the housing or the sleeve. In this way, the first electrode and the second electrode are hidden inside the connector, reducing the possibility of damage to the first electrode and the second electrode.

[0026] In a possible implementation, the power source is a battery, and the discharge of the first electrode and the second electrode can be controlled by controlling a corresponding switch of the power source.

[0027] In a possible implementation, the power source is a piezoelectric power source. The piezoelectric power source may be a piezoelectric ceramic or other piezoelectric material. The first electrode and the second electrode are respectively connected to two sides of the piezoelectric power source. When the piezoelectric power source is struck, a pressure difference is generated on both sides of the piezoelectric power source and transmitted to the first electrode and the second electrode, so that the first electrode and the second electrode generate a high-voltage discharge.

[0028] In a possible implementation, during the docking process between the optical fiber connector and the optical fiber adapter, the power source is used to supply power to the first electrode and the second electrode under the triggering of the optical fiber connector.

[0029] In a possible implementation, the housing has a snap-in slot inside, and the snap-in slot is used to snap-in with the snap-in of the elastic arm of the optical fiber connector. The power supply is located in the snap-in slot, and the snap-in is used to apply pressure to the power supply when snap-in with the snap-in slot. This solution is applicable to the scenario where the optical fiber connector matched with the optical fiber adapter has an elastic arm, for example, the optical fiber adapter and the optical fiber connector are respectively an LC type optical fiber adapter and an LC type optical fiber connector.

[0030] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the optical fiber adapter, the elastic arm is squeezed by the inner wall of the shell, and when the buckle moves to the clamping groove, the buckle loses its obstruction, and the elastic arm extends, the buckle extends into the clamping groove, and hits the power supply in the clamping groove, so that the discharge component discharges. It can be seen that by setting the power supply in the clamping groove, during the docking process between the optical fiber adapter and the optical fiber connector, the buckle of the optical fiber connector will automatically trigger the discharge of the discharge component and complete the cleaning of the end face of the optical fiber ferrule, and the user does not need to perform extra operations, and the operation is simple.

[0031] In a possible implementation, the inner wall of the housing has a protrusion, which is located on the docking path of the elastic arm of the optical fiber connector and in front of the clamping groove. During the docking process between the optical fiber connector and the optical fiber adapter, the protrusion is used to squeeze the elastic arm of the optical fiber connector and store energy in the elastic arm. The setting of the above-mentioned protrusion can increase the pressure applied by the buckle to the power supply and increase the speed at which the buckle hits the power supply, which improves the success rate of discharge of the discharge component.

[0032] In a possible implementation, the side of the protrusion that contacts the elastic arm is a first inclined surface, and the height of the first inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that the height of the first inclined surface protruding from the inner wall of the shell gradually increases along the mating direction of the optical fiber connector. In this way, the smoothness of the mating between the optical fiber connector and the optical fiber adapter can be improved. Among them, the mating direction of the optical fiber connector can also be understood as the insertion direction, access direction or extension direction of the optical fiber connector.

[0033] In a possible implementation, there are two groups of power supplies, and the two groups of power supplies are respectively located in the first accommodating area and the second accommodating area of ​​the housing. The first accommodating area and the second accommodating area are respectively used to accommodate different optical fiber connectors. In this way, during the docking process of any optical fiber connector, the discharge assembly will be triggered to discharge, so that the optical fiber cores of the two optical fiber connectors can be cleaned.

[0034] In a possible implementation, the discharge assembly further includes a first trigger. The first trigger is movably connected to the housing and is located on the docking path of the optical fiber connector. The power supply is located on the movable path of the first trigger. During the docking process between the optical fiber connector and the housing, the first trigger is used to apply pressure to the power supply under the drive of the optical fiber connector. This solution can be applied to all types of optical fiber adapters.

[0035] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the optical fiber adapter, since the first triggering member is located on the docking path of the optical fiber connector, the optical fiber connector will contact the first triggering member and drive the first triggering member to move. Since the power supply is located on the active path of the first triggering member, the first triggering member will apply pressure to the power supply and cause the discharge component to discharge. It can be seen that the design of the above-mentioned first triggering member enables the discharge component to automatically discharge and clean the end face of the optical fiber ferrule during the docking process between the optical fiber adapter and the optical fiber connector, and the user does not need to perform extra operations, and the operation is simple.

[0036] In a possible implementation, the first triggering member is located on the inner wall of the housing and can be extended and retracted relative to the inner wall of the housing. The power source is located on the retractable path of the first triggering member.

[0037] In a possible implementation, the first trigger member has a second inclined surface, and the height of the second inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that the height of the second inclined surface protruding from the inner wall of the housing gradually increases along the mating direction of the optical fiber connector. In this way, the smoothness of the mating between the optical fiber connector and the optical fiber adapter can be improved.

[0038] In a possible implementation, there are two first trigger members, and the two first trigger members are respectively located in the first accommodation area and the second accommodation area of ​​the housing. The first accommodation area and the second accommodation area are respectively used to accommodate different optical fiber connectors. In this way, during the docking process of any optical fiber connector, the discharge assembly will be triggered to discharge, so that the optical fiber cores of the two optical fiber connectors can be cleaned.

[0039] In a possible implementation, when the optical fiber connector triggers the discharge assembly to discharge through the first triggering member, the optical fiber ferrule of the optical fiber connector has not yet reached the docking position.

[0040] In a possible implementation, the discharge assembly further includes a second triggering member. The second triggering member is movably connected to the housing and exposed outside the housing. The power source is located on the movable path of the second triggering member, and the second triggering member is used to apply pressure to the power source.

[0041] The second triggering member is for user operation. When using the optical fiber adapter, the optical fiber adapter is first connected to the optical fiber connector, and then the second triggering member is operated to trigger the discharge assembly to discharge.

[0042] The technical solution provided by the present disclosure, by providing a second triggering member operated by the user, enables the user to independently select the time for the discharge assembly to discharge. In this way, when the user observes that the end face of the optical fiber ferrule is sufficiently clean, there is no need to operate the second triggering member to trigger the discharge assembly to discharge, thereby increasing the life of the discharge assembly.

[0043] In a possible implementation, the second triggering member is a pressing member, and the user can apply pressure to the power source by pressing the second triggering member, and discharge the first electrode and the second electrode. The second triggering member is slidably connected to the housing, and the power source is located on the sliding path of the second triggering member.

[0044] In a second aspect, the present disclosure provides a fiber optic connection assembly, which includes a fiber optic connector and a fiber optic adapter as described in any one of the first aspects.

[0045] In a third aspect, the present disclosure provides a fiber optic ferrule cleaner. The fiber optic ferrule cleaner includes a housing and a discharge assembly. At least one end of the housing has an interface for docking a fiber optic connector, and the housing is used to accommodate the fiber optic ferrule of the fiber optic connector. The discharge assembly is connected to the housing, and the discharge assembly is used to discharge inside the housing.

[0046] The optical fiber connector to which the optical fiber ferrule cleaner is connected may be an LC optical fiber connector, an FC optical fiber connector, an SC optical fiber connector, an ST optical fiber connector, an MU optical fiber connector, an MT optical fiber connector, a DIN optical fiber connector, a D4 optical fiber connector, etc. The optical fiber ferrule includes a ferrule and an optical fiber, and a fixing hole is provided at the center of the ferrule, and the optical fiber is located in the fixing hole. The ferrule may be a ceramic ferrule, but is not limited thereto.

[0047] The technical solution provided by the present disclosure is that when using the fiber optic ferrule cleaner, the fiber optic connector is first docked with the fiber optic ferrule cleaner, and then the discharge component is triggered to discharge to clean the end face of the fiber optic ferrule of the fiber optic connector. After that, the cleaned fiber optic connector is docked with the fiber optic adapter, thereby improving the reliability of the optical transmission system. In addition, compared with using dustproof paper and dustproof cloth to clean the end face of the fiber optic ferrule, the fiber optic ferrule cleaner provided by the present disclosure will not scratch the end face of the fiber optic ferrule, and it is not easy to transfer dirt on the end face of the ferrule to the end face of the optical fiber. In addition, the fiber optic ferrule cleaner is non-disposable, has a low cost, and can be used in a wider range of scenarios.

[0048] In a possible implementation, the discharge voltage of the discharge assembly is greater than 1 kV, so that the cleaning effect on the end face of the optical fiber ferrule can be guaranteed.

[0049] In a possible implementation, the discharge voltage of the discharge component is less than 12 kV to prevent the electricity discharged by the discharge component from damaging the optical fiber ferrule.

[0050] In a possible implementation, the discharge voltage of the discharge assembly is less than 5 kV to further reduce the possibility of damage to the optical fiber ferrule.

[0051] In a possible implementation, the discharge assembly includes a power supply, a first electrode, and a second electrode. The power supply is electrically connected to the first electrode and the second electrode. The first electrode and the second electrode are located inside the housing and face each other, and the first electrode and the second electrode are used for discharge.

[0052] The opposite ends of the first electrode and the second electrode are sharp. When the power source supplies power to the first electrode and the second electrode, the first electrode and the second electrode generate instantaneous high voltage and break through the air between the first electrode and the second electrode, so that an arc is generated between the first electrode and the second electrode, and the arc can clean the end face of the optical fiber ferrule.

[0053] In a possible implementation manner, the first electrode and the second electrode are needle-shaped electrodes.

[0054] In a possible implementation, the first electrode and the second electrode are coaxially arranged, and the line between the first electrode and the second electrode intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule. In this way, the arc generated between the first electrode and the second electrode can pass through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0055] In a possible implementation, the discharge assembly further includes a wire, and the power source is electrically connected to the first electrode and the second electrode through the wire.

[0056] In a possible implementation manner, the wire is embedded in a shell wall of the shell.

[0057] In a possible implementation, the optical fiber ferrule cleaner further includes a sleeve. The sleeve is located inside the housing and is used to accommodate the optical fiber ferrule. The first electrode and the second electrode are located on both sides of the sleeve, and the first electrode and the second electrode are used to discharge inside the sleeve. The sleeve is used to accommodate the optical fiber ferrule of the optical fiber connector, and by discharging the first electrode and the second electrode inside the sleeve, the optical fiber ferrule can be cleaned.

[0058] In one possible implementation, the line between the first electrode and the second electrode intersects and is perpendicular to the central axis of the sleeve, so that the arc generated between the first electrode and the second electrode can pass through the center of the end face of the optical fiber ferrule, that is, through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0059] In a possible implementation, the wall of the sleeve is provided with a first opening and a second opening opposite to each other. The first electrode extends into the first opening, and the second electrode extends into the second opening. In this way, when the first electrode and the second electrode discharge, the air between the first electrode and the second electrode is easily broken through.

[0060] In a possible implementation manner, the first electrode and the second electrode are contracted relative to the inner wall of the sleeve.

[0061] In a possible implementation, the optical fiber ferrule cleaner further includes a connector, and the sleeve is connected to the housing through the connector. The first electrode and the second electrode are fixed inside the connector. In this way, the first electrode and the second electrode are hidden inside the connector, reducing the possibility of damage to the first electrode and the second electrode.

[0062] In a possible implementation, the power source is a battery, and the discharge of the first electrode and the second electrode can be controlled by controlling the corresponding switch of the power source. The battery can be arranged outside the housing and electrically connected to the first electrode and the second electrode through an external wire.

[0063] In a possible implementation, the power source is a piezoelectric power source, and by applying pressure to the power source (or called striking the power source), the discharge of the first electrode and the second electrode can be controlled. The power source can be a piezoelectric ceramic or other piezoelectric material. The first electrode and the second electrode are respectively connected to the two sides of the power source. When the power source is struck, a pressure difference is generated on both sides of the power source and transmitted to the first electrode and the second electrode, so that the first electrode and the second electrode generate high-voltage discharge.

[0064] In a possible implementation, during the docking process between the optical fiber connector and the optical fiber ferrule cleaner, the power supply is used to supply power to the first electrode and the second electrode under the triggering of the optical fiber connector.

[0065] In a possible implementation, the housing has a snap-in slot inside, and the snap-in slot is used to snap-in with the snap-in of the elastic arm of the optical fiber connector. The power supply is located in the snap-in slot, and the snap-in is used to apply pressure to the power supply when snap-in with the snap-in slot. Among them, this solution is suitable for the scenario where the optical fiber connector to which the optical fiber core cleaner is connected has an elastic arm, for example, the optical fiber connector is an LC type optical fiber connector.

[0066] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the optical fiber ferrule cleaner, the elastic arm of the optical fiber connector is squeezed by the inner wall of the shell, and when the buckle moves to the clamping groove, the buckle loses its obstruction, and the elastic arm extends, the buckle extends into the clamping groove, and hits the power supply in the clamping groove, so that the discharge component discharges. It can be seen that by setting the power supply in the clamping groove, during the docking process between the optical fiber ferrule cleaner and the optical fiber connector, the buckle of the optical fiber connector will automatically trigger the discharge of the discharge component and complete the cleaning of the end face of the optical fiber ferrule, and the user does not need to perform extra operations, and the operation is simple.

[0067] In a possible implementation, the inner wall of the housing has a protrusion, which is located on the docking path of the elastic arm of the optical fiber connector and in front of the clamping groove. In this way, during the docking process between the optical fiber connector and the optical fiber ferrule cleaner, the elastic arm of the optical fiber connector is first squeezed by the protrusion and stores energy, and then, when the buckle reaches the clamping groove, the elastic arm rebounds and drives the buckle to hit the power supply. The design of the protrusion increases the pressure applied by the buckle to the power supply and increases the hitting speed.

[0068] In a possible implementation, the side of the protrusion that contacts the elastic arm is a first inclined surface, and the height of the first inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that along the mating direction of the optical fiber connector, the height of the first inclined surface protruding from the inner wall of the shell gradually increases. In this way, the smoothness of the mating between the optical fiber connector and the optical fiber ferrule cleaner can be improved.

[0069] In a possible implementation, the discharge assembly further includes a first trigger. The first trigger is movably connected to the housing and is located on a docking path of the optical fiber connector. The power source is located on the movable path of the first trigger. During the docking process between the optical fiber connector and the optical fiber ferrule cleaner, the first trigger is used to apply pressure to the power source under the drive of the optical fiber connector.

[0070] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the optical fiber ferrule cleaner, since the first trigger member is located on the docking path of the optical fiber connector, the optical fiber connector will contact the first trigger member and drive the first trigger member to move. Since the power supply is located on the active path of the first trigger member, the first trigger member will apply pressure to the power supply and cause the discharge component to discharge. It can be seen that the design of the above-mentioned first trigger member enables the discharge component to automatically discharge and clean the end face of the optical fiber ferrule during the docking process between the optical fiber ferrule cleaner and the optical fiber connector, and the user does not need to perform extra operations, and the operation is simple.

[0071] In a possible implementation, the first triggering member is located on the inner wall of the housing and can be extended and retracted relative to the inner wall of the housing. The power source is located on the retractable path of the first triggering member.

[0072] In a possible implementation, the first trigger member has a second inclined surface, and the height of the second inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that along the mating direction of the optical fiber connector, the height of the second inclined surface protruding from the inner wall of the housing gradually increases. In this way, the smoothness of the mating of the optical fiber connector can be improved.

[0073] In a possible implementation, the discharge assembly further includes a second trigger. The second trigger is movably connected to the housing and exposed outside the housing. The power source is located on the movable path of the second trigger, and the second trigger is used to apply pressure to the power source. The second trigger is used for user operation. When using the optical fiber ferrule cleaner, the optical fiber ferrule cleaner is first docked with the optical fiber connector, and then the second trigger is operated to trigger the discharge assembly to discharge.

[0074] In a possible implementation, the structure of the optical fiber ferrule cleaner is the same as that of the optical fiber adapter of the first aspect.

[0075] In a fourth aspect, the present disclosure provides an optical device. The optical device has an interface component, which includes a housing and a discharge assembly. The housing has an interface for docking an optical fiber connector, and the housing is used to accommodate an optical fiber ferrule of the optical fiber connector. The discharge assembly is fixed to the housing, and the discharge assembly is used to discharge inside the housing to clean the end face of the optical fiber ferrule.

[0076] The optical device provided by the present disclosure may be any device having an interface component for docking an optical fiber connector. The optical device may be an optical communication module, an optical instrument (such as a spectrometer), a passive optical function module (for example, an optical switch and a comb filter), an optical amplifier, and an optical fiber junction box. The optical fiber connector docked by the interface component may be an LC optical fiber connector, an FC optical fiber connector, an SC optical fiber connector, an ST optical fiber connector, an MU optical fiber connector, an MT optical fiber connector, a DIN optical fiber connector, and a D4 optical fiber connector.

[0077] The technical solution provided by the present disclosure is to set a discharge component for discharging inside a shell in the interface component of the optical device, so that during the docking process between the optical fiber connector and the interface component of the optical device, the discharge of the discharge component can be triggered to clean the end face of the optical fiber ferrule of the optical fiber connector, thereby improving the cleanliness of the end face of the optical fiber ferrule and improving the reliability of the optical transmission system.

[0078] In a possible implementation, the interface component further has a fiber optic ferrule, which is used to connect with the fiber optic ferrule of the fiber optic connector.

[0079] In a possible implementation, the discharge component is used to discharge before the optical fiber ferrule of the optical fiber connector reaches the docking position.

[0080] The technical solution provided by the present disclosure is that when the optical fiber ferrules of the optical fiber connector both reach the docking position, the end faces of the optical fiber ferrules of the optical fiber connector will be in close contact with the end faces of the optical fiber ferrules of the interface component. If discharge is performed at this time, the end faces of the optical fiber ferrules cannot be cleaned. Therefore, by setting a discharge component to discharge before the optical fiber ferrules of the optical fiber connector reach the docking position, the end faces of the two optical fiber ferrules can be cleaned.

[0081] In a possible implementation, the discharge voltage of the discharge assembly is greater than 1 kV, so that the cleaning effect on the end face of the optical fiber ferrule can be guaranteed.

[0082] In a possible implementation, the discharge voltage of the discharge component is less than 12 kV to prevent the electricity discharged by the discharge component from damaging the optical fiber ferrule.

[0083] In a possible implementation, the discharge voltage of the discharge assembly is less than 5 kV to further reduce the possibility of damage to the optical fiber ferrule.

[0084] In a possible implementation, the discharge assembly includes a power supply, a first electrode, and a second electrode. The power supply is electrically connected to the first electrode and the second electrode. The first electrode and the second electrode are located inside the housing and face each other, and the first electrode and the second electrode are used for discharge.

[0085] The opposite ends of the first electrode and the second electrode are sharp. When the power source supplies power to the first electrode and the second electrode, the first electrode and the second electrode generate instantaneous high voltage and break through the air between the first electrode and the second electrode, so that an arc is generated between the first electrode and the second electrode, and the arc can clean the end face of the optical fiber ferrule.

[0086] In a possible implementation manner, the first electrode and the second electrode are needle-shaped electrodes.

[0087] In a possible implementation, the first electrode and the second electrode are coaxially arranged, and the line between the first electrode and the second electrode intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule. In this way, the arc generated between the first electrode and the second electrode can pass through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0088] In a possible implementation, the discharge assembly further includes a wire, and the power source is electrically connected to the first electrode and the second electrode through the wire.

[0089] In a possible implementation manner, the wire is embedded in a shell wall of the shell.

[0090] In a possible implementation, the interface component further includes a sleeve. The sleeve is located inside the housing and is used to accommodate the optical fiber ferrule. The first electrode and the second electrode are located on both sides of the sleeve and are used to discharge inside the sleeve.

[0091] In a possible implementation, the interface component further has an optical fiber ferrule, and the optical fiber ferrule extends into the interior of the sleeve. The optical fiber ferrule is used to dock with the optical fiber ferrule of the optical fiber connector.

[0092] In one possible implementation, the line between the first electrode and the second electrode intersects and is perpendicular to the central axis of the sleeve, so that the arc generated between the first electrode and the second electrode can pass through the center of the end face of the optical fiber ferrule, that is, through the end face of the optical fiber, thereby improving the cleaning effect of the end face of the optical fiber.

[0093] In a possible implementation, the wall of the sleeve is provided with a first opening and a second opening opposite to each other. The first electrode extends into the first opening, and the second electrode extends into the second opening. In this way, when the first electrode and the second electrode discharge, the air between the first electrode and the second electrode is easily broken through.

[0094] In a possible implementation manner, the first electrode and the second electrode are contracted relative to the inner wall of the sleeve.

[0095] In a possible implementation, the interface component further includes a connector. The sleeve is connected to the housing through the connector. The first electrode and the second electrode are fixed inside the connector. In this way, the first electrode and the second electrode are hidden inside the connector, reducing the possibility of damage to the first electrode and the second electrode.

[0096] In a possible implementation, the power source is a piezoelectric power source, and by applying pressure to the power source (or called striking the power source), the discharge of the first electrode and the second electrode can be controlled. The power source can be a piezoelectric ceramic or other piezoelectric material. The first electrode and the second electrode are respectively connected to the two sides of the power source. When the power source is struck, a pressure difference is generated on both sides of the power source and transmitted to the first electrode and the second electrode, so that the first electrode and the second electrode generate high-voltage discharge.

[0097] In a possible implementation, during the docking process between the optical fiber connector and the interface component of the optical device, the power supply is used to supply power to the first electrode and the second electrode under the triggering of the optical fiber connector.

[0098] In a possible implementation, the housing has a snap-in slot inside, and the snap-in slot is used to snap-in with the snap-in of the elastic arm of the optical fiber connector. The power supply is located in the snap-in slot, and the snap-in is used to apply pressure to the power supply when snap-in with the snap-in slot. This solution is applicable to the scenario where the optical fiber connector connected to the interface component of the optical device has an elastic arm, for example, the optical fiber connector is an LC type optical fiber connector.

[0099] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the interface component of the optical device, the elastic arm of the optical fiber connector is squeezed by the inner wall of the shell, and when the buckle moves to the clamping groove, the buckle loses its obstruction, and the elastic arm extends, the buckle extends into the clamping groove, and hits the power supply in the clamping groove, so that the discharge component discharges. It can be seen that by setting the power supply in the clamping groove, during the docking process between the interface component of the optical device and the optical fiber connector, the buckle of the optical fiber connector will automatically trigger the discharge of the discharge component and complete the cleaning of the end face of the optical fiber ferrule, and the user does not need to perform extra operations, and the operation is simple.

[0100] In a possible implementation, the inner wall of the housing has a protrusion, which is located on the docking path of the elastic arm of the optical fiber connector and in front of the clamping groove. In this way, during the docking process between the optical fiber connector and the interface component of the optical device, the elastic arm of the optical fiber connector is first squeezed by the protrusion and stores energy, and then, when the buckle reaches the clamping groove, the elastic arm rebounds and drives the buckle to hit the power supply. The design of the protrusion increases the pressure applied by the buckle to the power supply and increases the hitting speed.

[0101] In a possible implementation, the side of the protrusion that contacts the elastic arm is a first inclined surface, and the height of the first inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that the height of the first inclined surface protruding from the inner wall of the housing gradually increases along the mating direction of the optical fiber connector. In this way, the smoothness of the mating between the optical fiber connector and the interface component of the optical device can be improved.

[0102] In a possible implementation, the discharge assembly further includes a first trigger. The first trigger is movably connected to the housing and is located on a docking path of the optical fiber connector. The power source is located on the movable path of the first trigger. During the docking process between the optical fiber connector and the interface component of the optical device, the first trigger is used to apply pressure to the power source under the drive of the optical fiber connector.

[0103] The technical solution provided by the present disclosure is that during the docking process between the optical fiber connector and the interface component of the optical device, since the first triggering member is located on the docking path of the optical fiber connector, the optical fiber connector will contact the first triggering member and drive the first triggering member to move. Since the power supply is located on the active path of the first triggering member, the first triggering member will apply pressure to the power supply and cause the discharge component to discharge. It can be seen that the design of the above-mentioned first triggering member enables the discharge component to automatically discharge and clean the end face of the optical fiber ferrule during the docking process between the interface component of the optical device and the optical fiber connector, and the user does not need to perform extra operations, and the operation is simple.

[0104] In a possible implementation, the first triggering member is located on the inner wall of the housing and can be extended and retracted relative to the inner wall of the housing. The power source is located on the retractable path of the first triggering member.

[0105] In a possible implementation, the first trigger member has a second inclined surface, and the height of the second inclined surface gradually increases along the mating direction of the optical fiber connector. Alternatively, it can also be understood that along the mating direction of the optical fiber connector, the height of the second inclined surface protruding from the inner wall of the housing gradually increases. In this way, the smoothness of the mating of the optical fiber connector can be improved.

[0106] In a possible implementation, the discharge assembly further includes a second trigger. The second trigger is movably connected to the housing and exposed outside the housing. The power source is located on the movable path of the second trigger, and the second trigger is used to apply pressure to the power source. The second trigger is used for user operation.

[0143] The optical fiber adapter 1 and the optical fiber connector 2 are devices for detachably connecting optical fibers. Figure 1 As shown, in actual application, two optical fiber connectors 2 are connected to the butt ends of two optical fibers, and the optical fiber adapter 1 butts the optical fiber ferrules 21 of the two optical fiber connectors 2 so that the optical energy output by the optical fiber at the transmitting end is coupled to the optical fiber at the receiving end to the maximum extent. Figure 2 As shown, the optical fiber ferrule 21 includes a ferrule 211 in the optical fiber connector and an optical fiber 212 located at the center of the ferrule 211. The ferrule 211 can be a ceramic ferrule, but is not limited thereto. The optical fiber 212 is fixed in a fixing hole at the center of the ferrule 211.

[0144] The optical fiber adapter 1 and the optical fiber connector 2 affect the insertion loss and return loss of the optical transmission system. During use, dirt may be introduced into the end face of the optical fiber ferrule 21, especially improper use is very likely to introduce dirt, for example, the optical fiber connector 2 is pulled out without a dust cap and the end face of the optical fiber ferrule 21 is touched by hand. Dirt can cause the insertion loss of the optical transmission system to deteriorate sharply, for example, the insertion loss deteriorates from 0.2dB to 3-10dB. In addition, dirt can also cause end face reflection, resulting in a decrease in the return loss value at the joint of the two optical fiber ferrules 21.

[0145] In the related art, in order to prevent dirt from entering the end face of the optical fiber ferrule 21, a passive anti-fouling design is often used, and a dust cap (or protective cover) is added to the optical fiber connector 2, for example, the E2000 optical fiber connector and adapter. When the optical fiber connector 2 is pulled out from the optical fiber adapter 1, the dust cap on the optical fiber connector 2 is closed to prevent dirt from contaminating the optical fiber ferrule 21. However, this passive anti-fouling design has the following technical problems.

[0146] First, the optical fiber adapter and optical fiber connector with such passive anti-fouling design cannot avoid the dirt introduced during the plugging and unplugging process, and after being dirty, it is difficult to clean the end face of the optical fiber ferrule 21 due to the closed dust cap. Secondly, as the use time goes by, the dirt accumulated inside the dust cap will also contaminate the end face of the optical fiber ferrule 21.

[0147] In addition, in the case where the end face of the optical fiber ferrule 21 has been contaminated, the cleaning technology used in the related art mainly relies on wiping with dustproof paper or dustproof cloth. However, this cleaning method is very easy to scratch the end face of the optical fiber ferrule 21, and during the cleaning process, it is easy to cause the dirt on the end face of the ferrule 211 to be transferred to the end face of the optical fiber 212 (refer to Figure 2 ), which deteriorates the performance of the optical transmission system. Furthermore, the dustproof paper and dustproof cloth are disposable, costly, and need to be kept clean. They are inconvenient to carry and use, and are particularly not suitable for harsh scenes such as outdoor.

[0148] In view of the above technical problems, the embodiment of the present disclosure provides a fiber optic adapter 1, which adopts an active anti-fouling design and can actively clean the end face of the fiber optic ferrule 21 of the fiber optic connector 2. The fiber optic adapter 1 is exemplarily described below.

[0149] like Figure 3 and Figure 4 As shown, the optical fiber adapter 1 includes a housing 11 and a discharge assembly 12. Both ends of the housing 11 have interfaces 110 for docking optical fiber connectors 2, and the housing 11 is used to dock the optical fiber ferrules 21 of the two optical fiber connectors 2. The discharge assembly 12 is fixed to the housing 11, and the discharge assembly 12 is used to discharge inside the housing 11.

[0150] The optical fiber adapter 1 can also be called an optical fiber flange. The embodiment of the present disclosure does not limit the docking form of the optical fiber adapter 1 and the optical fiber connector 2. The optical fiber adapter 1 and the optical fiber connector 2 can be connected by snapping and threading, etc. The optical fiber adapter 1 provided in the embodiment of the present disclosure can be a lucent connector (lucent connector / local connector, LC) type optical fiber adapter, a ferrule connector (ferrule connector, FC) type optical fiber adapter, a subscriber connector / standard connector / square connector (subscriber connector / standard connector / square connector, SC) type optical fiber adapter, a straight tip (straight tip, ST) type optical fiber adapter, a miniature unit coupling (miniature unit coupling, MU) type optical fiber adapter, a mechanical transfer (mechanical transfer, MT) type optical fiber adapter, a DIN type optical fiber adapter, and a D4 type optical fiber adapter.

[0151] It should be noted that the optical fiber adapter 1 provided in the embodiment of the present disclosure can also be used to connect two different types of optical fiber connectors 2, that is, the two interfaces 110 of the optical fiber adapter 1 conform to different connector standards. For example, the two interfaces 110 of the optical fiber adapter 1 are respectively used to connect an LC optical fiber connector and an SC optical fiber connector.

[0152] The technical solution provided by the embodiment of the present disclosure is that a discharge component 12 for discharging inside the shell 11 is set in the optical fiber adapter 1, so that during the process of docking the optical fiber adapter 1 with the optical fiber connector 2, the discharge of the discharge component 12 can be triggered to clean the end face of the optical fiber ferrule 21 of the optical fiber connector 2, thereby improving the cleanliness of the end face of the optical fiber ferrule 21 and improving the reliability of the optical transmission system.

[0153] The embodiment of the present disclosure does not specifically limit the discharge voltage of the discharge component 12, as long as it can clean the end face of the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is greater than 1 kV. In addition, the discharge voltage of the discharge component 12 should not be too high to avoid damaging the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is less than 12 kV. In other examples, in order to further reduce the possibility of damage to the optical fiber ferrule 21, the discharge voltage of the discharge component 12 is less than 5 kV.

[0154] Below, the implementation of the discharge component 12 is exemplified. In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19As shown, the discharge assembly 12 includes a power supply 121, a first electrode 122 and a second electrode 123. The power supply 121 is electrically connected to the first electrode 122 and the second electrode 123. The first electrode 122 and the second electrode 123 are located inside the housing 11 and face each other, and the first electrode 122 and the second electrode 123 are arranged at intervals.

[0155] The opposite ends of the first electrode 122 and the second electrode 123 are sharp. The first electrode 122 and the second electrode 123 may be needle-shaped electrodes. When the power supply 121 supplies power to the first electrode 122 and the second electrode 123, the first electrode 122 and the second electrode 123 generate instantaneous high voltage and break through the air between the first electrode 122 and the second electrode 123, so that an arc is generated between the first electrode 122 and the second electrode 123, and the arc can clean the end face of the optical fiber ferrule 21.

[0156] In some examples, such as Figure 5 , Fig. 9 , Fig.11 , Figure 13-Figure 15 , Fig.17 and Fig.18 As shown, the first electrode 122 and the second electrode 123 are coaxially arranged, and the line between the first electrode 122 and the second electrode 123 intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the end face of the optical fiber 212, thereby improving the cleaning effect of the end face of the optical fiber 212.

[0157] In some examples, such as Figure 5 , Fig. 9 , Fig.11 , Figure 13-Figure 15 , Fig.17 and Fig.18 As shown, the first electrode 122 and the second electrode 123 are opposite to the butt joint positions of the two optical fiber ferrules 21. Alternatively, it can be understood that the connection line of the first electrode 122 and the second electrode 123 passes through the butt joint positions of the two optical fiber ferrules 21. In this way, the end faces of the two optical fiber ferrules 21 can be cleaned by a set of first electrodes 122 and second electrodes 123, which reduces the number of components required for the optical fiber adapter 1 and reduces the cost of the optical fiber adapter 1.

[0158] In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19 As shown, the discharge assembly 12 further includes a wire 126, and the power source 121 is electrically connected to the first electrode 122 and the second electrode 123 via the wire 126. The wire 126 is embedded in the housing 11.

[0159] Next, the positions of the first electrode 122 and the second electrode 123 are described in more detail.

[0160] In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19 As shown, the optical fiber adapter 1 further includes a sleeve 13. The sleeve 13 is located inside the housing 11. The first electrode 122 and the second electrode 123 are located on both sides of the sleeve 13, and the first electrode 122 and the second electrode 123 are used for discharging inside the sleeve 13.

[0161] The sleeve 13 is used to accommodate the optical fiber ferrules 21 of the two optical fiber connectors 2 , and the optical fiber ferrules 21 can be cleaned by discharging the first electrode 122 and the second electrode 123 inside the sleeve 13 .

[0162] In some examples, the line between the first electrode 122 and the second electrode 123 intersects and is perpendicular to the central axis of the sleeve 13, wherein the central axis of the sleeve 13 is collinear with the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the center of the end face of the optical fiber ferrule 21, that is, through the end face of the optical fiber 212, thereby improving the cleaning effect on the optical fiber 212.

[0163] In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19 As shown, the wall of the sleeve 13 is provided with a first opening 131 and a second opening 132 opposite to each other. The first electrode 122 extends into the first opening 131, and the second electrode 123 extends into the second opening 132. In this way, it is convenient for the first electrode 122 and the second electrode 123 to break through the air between the first electrode 122 and the second electrode 123 when they discharge.

[0164] In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19 As shown, the first electrode 122 and the second electrode 123 are retracted relative to the inner wall of the sleeve 13. In this way, the first electrode 122 and the second electrode 123 can be prevented from colliding with the optical fiber connector 2 and being damaged.

[0165] In some examples, such as Figure 5 , Fig. 9 and Figure 11-Figure 19 As shown, the optical fiber adapter 1 further includes a connector 14, and the sleeve 13 is connected to the housing 11 through the connector 14. The first electrode 122 and the second electrode 123 are fixed inside the connector 14. In this way, the first electrode 122 and the second electrode 123 are hidden inside the connector 14, reducing the possibility of damage to the first electrode 122 and the second electrode 123.

[0166] The moment when the discharge component 12 discharges is exemplified below. Since the optical fiber adapter 1 needs to dock with two optical fiber connectors 2, and when the optical fiber ferrules 21 of the two optical fiber connectors 2 reach the docking position, the end faces of the two optical fiber ferrules 21 will be in close contact, and if discharge is performed at this time, it will not be able to clean the end faces of the optical fiber ferrules 21. Therefore, in some examples, the discharge component 12 is set to discharge before the optical fiber ferrule 21 reaches the docking position, so that the end faces of the optical fiber ferrules 21 can be cleaned.

[0167] Of course, the end faces of the two optical fiber ferrules 21 will be in close contact only when the second optical fiber connector 2 is inserted. Therefore, the discharge component 12 can be set to discharge before the optical fiber ferrule 21 of the second optical fiber connector 2 reaches the docking position, and for the optical fiber ferrule 21 of the first optical fiber connector 2, it can be set to discharge before the optical fiber ferrule 21 reaches the docking position, or it can be set to discharge when the optical fiber ferrule 21 reaches the docking position.

[0168] In addition, the embodiment of the present disclosure does not limit the number of discharges of the discharge component 12. In some examples, during the docking process of the two optical fiber connectors 2 and the optical fiber adapter 1, the discharge component 12 discharges, that is, the discharge component 12 discharges twice, and the two discharges are respectively used to clean the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2. Of course, the second discharge can play a role in cleaning the end faces of both optical fiber ferrules 21.

[0169] In other examples, the discharge assembly 12 discharges only during the docking process between the second optical fiber connector 2 and the optical fiber adapter 1, that is, the discharge assembly 12 discharges once, and the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2 are cleaned simultaneously by one discharge. In some examples, for this solution, the discharge assembly 12 is set to discharge before the optical fiber ferrule 21 reaches the docking position.

[0170] It should be noted that, in addition to the above technical solution in which the first electrode 122 and the second electrode 123 are a group, in other examples, such as Fig.12 , Fig.16 and Fig.19As shown, there are two discharge components 12, and the first electrode 122 and the second electrode 123 are two groups (each group of the first electrode 122 and the second electrode 123 can be called an electrode pair), and the two groups of the first electrode 122 and the second electrode 123 are respectively located on both sides of the docking position (the position shown by the dotted line in the figure) of the two optical fiber ferrules 21, and the two groups of the first electrode 122 and the second electrode 123 are respectively used to clean the end faces of the two optical fiber ferrules 21. Correspondingly, there are also two (or two groups) power supplies 121, and the two power supplies 121 are respectively used to supply power to the two groups of the first electrode 122 and the second electrode 123.

[0171] In some examples, for a scenario where the first electrode 122 and the second electrode 123 are two groups, discharge is set when the end face of the optical fiber ferrule 21 of the optical fiber connector 2 moves to a position between the corresponding first electrode 122 and the second electrode 123 to achieve an optimal cleaning effect.

[0172] The disclosed embodiments do not limit the type of power source 121. In some examples, power source 121 is a battery, and the first electrode 122 and the second electrode 123 can be controlled to discharge by controlling the corresponding switch of power source 121. In other examples, power source 121 is a piezoelectric power source, and the first electrode 122 and the second electrode 123 can be controlled to discharge by applying pressure to power source 121 (or hitting power source 121).

[0173] In the case where the power source 121 is a piezoelectric power source, the power source 121 may be a piezoelectric ceramic or other piezoelectric material. The first electrode 122 and the second electrode 123 are respectively connected to the two sides of the power source 121. When the power source 121 is struck, a pressure difference is generated on the two sides of the power source 121 and transmitted to the first electrode 122 and the second electrode 123, so that the first electrode 122 and the second electrode 123 generate high-voltage discharge.

[0174] In the following, the power source 121 is taken as a piezoelectric power source to explain the triggering method of the discharge of the discharge component 12. In some examples, during the docking process between the optical fiber connector 2 and the optical fiber adapter 1, the optical fiber connector 2 applies pressure to the power source 121 and automatically triggers the discharge of the discharge component 12. In other examples, the discharge of the discharge component 12 can also be manually triggered by the user. In the following, three triggering methods of the discharge component 12 are provided, wherein the first two triggering methods are automatic triggering methods, and the third triggering method is a manual triggering method.

[0175] (1) Figure 5-Figure 12As shown, the housing 11 has a snap-in groove 111 inside, and the snap-in groove 111 is used to snap-in with the snap-in 221 of the elastic arm 22 of the optical fiber connector 2. The power supply 121 is located in the snap-in groove 111, and the snap-in 221 is used to apply pressure to the power supply 121 when snap-in with the snap-in groove 111. Among them, this solution is suitable for the scene where the optical fiber connector 2 connected to the optical fiber adapter 1 has an elastic arm 22, for example, the optical fiber adapter 1 and the optical fiber connector 2 are LC type optical fiber adapter and LC type optical fiber connector respectively.

[0176] The technical solutions provided by the embodiments of the present disclosure are as follows: Figure 6 and Figure 7 As shown, during the docking process between the optical fiber connector 2 and the optical fiber adapter 1, the elastic arm 22 is squeezed by the inner wall of the shell 11. When the buckle 221 moves to the snap-in groove 111, the buckle 221 loses its obstruction, and the elastic arm 22 extends, and the buckle 221 extends into the snap-in groove 111 and hits the power supply 121 in the snap-in groove 111, causing the discharge component 12 to discharge.

[0177] It can be seen that by setting the power supply 121 in the snap-in groove 111, during the docking process between the optical fiber adapter 1 and the optical fiber connector 2, the snap 221 of the optical fiber connector 2 will automatically trigger the discharge assembly 12 to discharge and complete the cleaning of the end face of the optical fiber ferrule 21. The user does not need to perform any extra operations, and the operation is simple.

[0178] In some examples, such as Figure 6-Figure 8 As shown, the elastic arm 22 of the optical fiber connector 2 has buckles 221 on both sides, and accordingly, the optical fiber adapter 1 has two groups of snap-in slots 111 and two groups of power supplies 121, each group of snap-in slots 111 includes two snap-in slots 111, and the two groups of snap-in slots 111 are respectively located in the first accommodating area 113 and the second accommodating area 114 of the housing 11. Each group of power supplies 121 includes two power supplies 121, and the four power supplies 121 are respectively located in the four snap-in slots 111. Among them, the first accommodating area 113 and the second accommodating area 114 are respectively used to accommodate two different optical fiber connectors 2. Of course, as Fig.11 As shown, the two groups of card slots 111 and the two groups of power supplies 121 can also be replaced by one group.

[0179] In order to increase the pressure applied by the buckle 221 to the power source 121 and increase the striking speed, in some examples, such as Fig. 9 and Fig.10 As shown, the inner wall of the housing 11 has a protrusion 112, which is located on the docking path of the elastic arm 22 of the optical fiber connector 2 and in front of the clamping groove 111. In this way, during the docking process between the optical fiber connector 2 and the optical fiber adapter 1, the elastic arm 22 of the optical fiber connector 2 is first squeezed by the protrusion 112 and stores energy, and then, when the buckle 221 reaches the clamping groove 111, the elastic arm 22 rebounds and drives the buckle 221 to hit the power source 121.

[0180] In some examples, such as Fig. 9 and Fig.10 As shown, in order to ensure smooth docking of the optical fiber connector 2, the side of the protrusion 112 that contacts the elastic arm 22 is a first inclined surface 1120, and the height of the first inclined surface 1120 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the first inclined surface 1120 protruding from the inner wall of the housing 11 gradually increases.

[0181] In some examples, such as Figure 5 , Fig. 9 and Fig.11 As shown, the first electrode 122 and the second electrode 123 are a group, and the cleaning of the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2 is achieved by the same first electrode 122 and the second electrode 123. Figure 5 , Fig. 9 and Fig.11 As shown, the first electrode 122 and the second electrode 123 are opposite to the butt joint positions of the two optical fiber ferrules 21 , or it can be understood that the connection line of the first electrode 122 and the second electrode 123 passes through the butt joint positions of the two optical fiber ferrules 21 .

[0182] In some examples, such as Figure 5 and Fig. 9 As shown, there are two groups of power supplies 121, and the two groups of power supplies 121 are respectively located in the clamping grooves 111 of the first accommodating area 113 and the second accommodating area 114 of the optical fiber adapter 1. The first accommodating area 113 and the second accommodating area 114 are respectively used to accommodate different optical fiber connectors 2. In this way, during the docking process of any optical fiber connector 2, the discharge assembly 12 will be triggered to discharge, so that the optical fiber ferrules 21 of the two optical fiber connectors 2 can be cleaned.

[0183] In other examples, such as Fig.11 As shown, the power source 121 is a group and is located in the clamping groove 111 of the first accommodating area 113 or the second accommodating area 114. In this case, when only one optical fiber connector 2 is docked with the optical fiber adapter 1, the discharge component 12 will be triggered to discharge, while the other optical fiber connector 2 will not be triggered to discharge when docked with the optical fiber adapter 1. Fig.11 The optical fiber adapter 1 shown is provided with a power source 121 only in the card slot 111 of the second accommodating area 114. Therefore, only when the optical fiber connector 2 is extended into the second accommodating area 114, the discharge component 12 will be triggered to discharge, and when the optical fiber connector 2 is extended into the first accommodating area 113, the discharge component 12 will not be triggered to discharge.

[0184] In order to clean the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2, a sequence can be set for the docking of the two optical fiber connectors 2. For example, Fig.11 The optical fiber adapter 1 shown is configured to firstly connect the optical fiber connector 2 inserted into the first accommodating area 113 with the optical fiber adapter 1, and then connect the optical fiber connector 2 inserted into the second accommodating area 114 with the optical fiber adapter 1. In this way, when the discharge assembly 12 discharges, both optical fiber ferrules 21 are located inside the sleeve 13, and the discharge assembly 12 discharges once, and the end faces of both optical fiber ferrules 21 can be cleaned.

[0185] It should be noted that, when both optical fiber ferrules 21 reach the docking position, the end faces of the two optical fiber ferrules 21 will be in close contact, and if discharge is performed at this time, the end faces of the optical fiber ferrules 21 cannot be cleaned. Therefore, the positions of the clamping groove 111 and the power source 121 can be designed so that when the clamp 221 of the optical fiber connector 2 hits the power source 121, the optical fiber ferrule 21 of the optical fiber connector 2 has not yet reached the docking position.

[0186] In other examples, such as Fig.12 As shown, the first electrode 122 and the second electrode 123 are two groups, and are powered by two groups of power supplies 121. The two groups of first electrodes 122 and second electrodes 123 are respectively used to clean the end faces of the two optical fiber ferrules 21. For example, Fig.12 As shown, the relative positions of the two groups of first electrodes 122 and second electrodes 123 are respectively located at the docking positions of the two optical fiber ferrules 21 ( Fig.12 On both sides of the position shown by the dotted line in FIG.

[0187] For example, Fig.12 As shown, two groups of power sources 121 are respectively located in the clamping grooves 111 of the first accommodating area 113 and the second accommodating area 114. In this way, when the optical fiber connector 2 is inserted into the first accommodating area 113, the buckle 221 of the optical fiber connector 2 hits the power source 121 located in the clamping groove 111 of the first accommodating area 113, and triggers the corresponding group of first electrodes 122 and second electrodes 123 to discharge. When another optical fiber connector 2 is inserted into the second accommodating area 114, the buckle 221 of the optical fiber connector 2 hits the power source 121 located in the clamping groove 111 of the second accommodating area 114, and triggers another group of first electrodes 122 and second electrodes 123 to discharge.

[0188] It should be noted that in order to improve the cleaning effect, the positions of the snap-in groove 111 and the power supply 121 can be designed so that when the end face of the optical fiber ferrule 21 moves to the relative position of a corresponding set of first electrodes 122 and second electrodes 123, the snap 221 of the optical fiber connector 2 just hits the power supply 121 and triggers the discharge component 12 to discharge.

[0189] (2) Figure 13-Figure 16 As shown, the discharge assembly 12 further includes a first trigger member 124. The first trigger member 124 is movably connected to the housing 11 and is located on the docking path of the optical fiber connector 2. The power source 121 is located on the movable path of the first trigger member 124. During the docking process between the optical fiber connector 2 and the optical fiber adapter 1, the optical fiber connector 2 drives the first trigger member 124 to apply pressure to the power source 121. Among them, this solution is applicable to all types of optical fiber adapters.

[0190] The technical solutions provided by the embodiments of the present disclosure are as follows: Fig.14 As shown, during the docking process between the optical fiber connector 2 and the optical fiber adapter 1, since the first trigger member 124 is located on the docking path of the optical fiber connector 2, the optical fiber connector 2 will contact the first trigger member 124 and drive the first trigger member 124 to move. Since the power source 121 is located on the active path of the first trigger member 124, the first trigger member 124 will apply pressure to the power source 121 and cause the discharge assembly 12 to discharge. It can be seen that the design of the first trigger member 124 enables the discharge assembly 12 to automatically discharge and clean the end face of the optical fiber ferrule 21 during the docking process between the optical fiber adapter 1 and the optical fiber connector 2, and the user does not need to perform extra operations, and the operation is simple.

[0191] In some examples, such as Figure 13-Figure 16 As shown, the first trigger member 124 is located on the inner wall of the housing 11 and can be retracted relative to the inner wall of the housing 11. The power source 121 is located on the retractable path of the first trigger member 124.

[0192] In some examples, such as Figure 13-Figure 16 As shown, in order to improve the smoothness of the docking of the optical fiber connector 2, the first trigger member 124 has a second inclined surface 1240, and the height of the second inclined surface 1240 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the second inclined surface 1240 protruding from the inner wall of the housing 11 gradually increases.

[0193] In some examples, such as Figure 13-Figure 15 As shown, the first electrode 122 and the second electrode 123 are a group, and the cleaning of the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2 is achieved by the same group of first electrodes 122 and second electrodes 123. Figure 13-Figure 15 As shown, the first electrode 122 and the second electrode 123 are opposite to the butt joint positions of the two optical fiber ferrules 21 , or it can be understood that the connection line of the first electrode 122 and the second electrode 123 passes through the butt joint positions of the two optical fiber ferrules 21 .

[0194] In some examples, such as Fig.13 and Fig.14As shown, there are two first trigger members 124, and the two first trigger members 124 are respectively located in the first accommodation area 113 and the second accommodation area 114 of the optical fiber adapter 1. The first accommodation area 113 and the second accommodation area 114 are respectively used to accommodate different optical fiber connectors 2. In this way, during the docking process of any optical fiber connector 2, the discharge assembly 12 will be triggered to discharge, so that the optical fiber ferrules 21 of the two optical fiber connectors 2 can be cleaned.

[0195] In other examples, such as Fig.15 As shown, there is only one first trigger member 124, and the first trigger member 124 is located in the first accommodation area 113 or the second accommodation area 114. In this case, when only one optical fiber connector 2 is docked with the optical fiber adapter 1, the discharge assembly 12 will be triggered to discharge, while when the other optical fiber connector 2 is docked with the optical fiber adapter 1, the discharge assembly 12 will not be triggered to discharge. For example, Fig.15 In the optical fiber adapter 1 shown, the first trigger member 124 is disposed in the second accommodating area 114. The discharge assembly 12 will be triggered to discharge only when the optical fiber connector 2 is extended into the second accommodating area 114. However, when the optical fiber connector 2 is extended into the first accommodating area 113, the discharge assembly 12 will not be triggered to discharge.

[0196] In order to clean the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2, the insertion sequence of the two optical fiber connectors 2 can be set. Fig.15 The optical fiber adapter 1 shown is configured to firstly connect the optical fiber connector 2 inserted into the first accommodating area 113 with the optical fiber adapter 1, and then connect the optical fiber connector 2 inserted into the second accommodating area 114 with the optical fiber adapter 1. In this way, when the discharge assembly 12 discharges, both optical fiber ferrules 21 are located inside the sleeve 13, and the discharge assembly 12 discharges once, and the end faces of both optical fiber ferrules 21 can be cleaned.

[0197] It should be noted that, when both optical fiber ferrules 21 reach the docking position, the end faces of the two optical fiber ferrules 21 will be in close contact, and if discharge is performed at this time, the end faces of the optical fiber ferrules 21 cannot be cleaned. Therefore, the position of the first trigger member 124 can be designed so that when the optical fiber connector 2 triggers the discharge assembly 12 to discharge through the first trigger member 124, the optical fiber ferrule 21 of the optical fiber connector 2 has not yet reached the docking position.

[0198] In some examples, such as Fig.16 As shown, the first electrode 122 and the second electrode 123 are two groups, and are powered by two power supplies 121 respectively. The two groups of first electrodes 122 and second electrodes 123 are respectively used to clean the end faces of the two optical fiber ferrules 21. Fig.16As shown, the relative positions of the two groups of first electrodes 122 and second electrodes 123 are respectively located at the docking positions of the two optical fiber ferrules 21 ( Fig.16 On both sides of the position shown by the dotted line in FIG.

[0199] Correspondingly, such as Fig.16 As shown, there are two first triggering members 124, which are respectively located in the first accommodation area 113 and the second accommodation area 114. Thus, when the optical fiber connector 2 extends into the first accommodation area 113, the optical fiber connector 2 triggers a group of first electrodes 122 and second electrodes 123 to discharge through the first triggering member 124 located in the first accommodation area 113. When the optical fiber connector 2 extends into the second accommodation area 114, the optical fiber connector 2 triggers another group of first electrodes 122 and second electrodes 123 to discharge through the first triggering member 124 located in the second accommodation area 114.

[0200] It should be noted that in order to improve the cleaning effect, the position of the first trigger member 124 can be designed so that when the end face of the optical fiber core 21 moves to the relative position of a corresponding set of first electrodes 122 and second electrodes 123, the optical fiber connector 2 just triggers the discharge component 12 to discharge through the first trigger member 124.

[0201] It should also be noted that, in the case where there are two first trigger members 124, the two first trigger members 124 can be symmetrically arranged (eg Fig.13 , Fig.14 and Fig.16 As shown), it can also be arranged asymmetrically, for example, the two first trigger members 124 can also be located on different sides of the housing 11.

[0202] (3) Figure 17-Figure 19 As shown, the discharge assembly 12 further includes a second trigger member 125. The second trigger member 125 is movably connected to the housing 11 and exposed outside the housing 11. The power source 121 is located on the movable path of the second trigger member 125, and the second trigger member 125 is used to apply pressure to the power source 121 under the operation of the user.

[0203] When the optical fiber adapter 1 is used, the optical fiber adapter 1 is first connected to the optical fiber connector 2 , and then the second triggering member 125 is operated to trigger the discharge assembly 12 to discharge.

[0204] The technical solution provided by the embodiment of the present disclosure, by providing the second triggering member 125 operated by the user, enables the user to independently select the time for the discharge assembly 12 to discharge, without having to discharge the discharge assembly 12 every time the optical fiber adapter 1 and the optical fiber connector 2 are docked. For example, when the user observes that the end face of the optical fiber ferrule 21 is clean enough, there is no need to operate the second triggering member 125 to trigger the discharge assembly 12 to discharge, thereby increasing the life of the discharge assembly 12.

[0205] In some examples, such as Figure 17-Figure 19 As shown, the second trigger member 125 is a pressing member, and the user can apply pressure to the power source 121 by pressing the second trigger member 125, and discharge the first electrode 122 and the second electrode 123. The second trigger member 125 is slidably connected to the housing 11, and the power source 121 is located on the sliding path of the second trigger member 125. For example, the power source 121 is opposite to the bottom end of the second trigger member 125.

[0206] In some examples, such as Fig.17 and Fig.18 As shown, the first electrode 122 and the second electrode 123 are a group, and the cleaning of the end faces of the optical fiber ferrules 21 of the two optical fiber connectors 2 is achieved by the same first electrode 122 and the second electrode 123. Fig.17 and Fig.18 As shown, the first electrode 122 and the second electrode 123 are opposite to the butt joint positions of the two optical fiber ferrules 21 , or it can be understood that the connection line of the first electrode 122 and the second electrode 123 passes through the butt joint positions of the two optical fiber ferrules 21 .

[0207] In some examples, such as Fig.17 As shown, there are two (or two groups) of power sources 121, and there are also two second triggering members 125, which are respectively used to apply pressure to the two power sources 121. In this way, the two power sources 121 are mutually active and standby, and when one power source 121 fails, the user can also trigger the discharge assembly 12 to discharge by operating the second triggering member 125 corresponding to the other power source 121.

[0208] Of course, in other examples, such as Fig.18 As shown, there may be only one second trigger member 125 .

[0209] In some examples, such as Fig.19 As shown, the first electrode 122 and the second electrode 123 are two groups, and the two groups of first electrodes 122 and second electrodes 123 are powered by two power supplies 121 respectively. The two groups of first electrodes 122 and second electrodes 123 are used to clean the end faces of the two optical fiber ferrules 21 respectively. Fig.19 As shown, the relative positions of the two groups of first electrodes 122 and second electrodes 123 are respectively located at the docking positions of the two optical fiber ferrules 21 ( Fig.19 On both sides of the position shown by the dotted line in FIG.

[0210] Correspondingly, such as Fig.19 As shown, there are two second trigger components 125 , and the two second trigger components 125 are respectively used to trigger the two power sources 121 to supply power.

[0211] It should be noted that, in the case where there are two second trigger members 125, the two second trigger members 125 can be symmetrically arranged (eg Fig.17 and Fig.19 As shown), it can also be arranged asymmetrically, for example, the two second trigger members 125 can also be located on different sides of the housing 11.

[0212] The present disclosure also provides an optical fiber connection assembly, such as Figure 1 and Figure 3 As shown, the optical fiber connection assembly includes an optical fiber adapter 1 and an optical fiber connector 2 .

[0213] The technical solution provided by the embodiment of the present disclosure, by applying the above-mentioned optical fiber adapter 1, enables the discharge component 12 in the optical fiber adapter 1 to discharge during the docking process between the optical fiber adapter 1 and the optical fiber connector 2, and cleans the end face of the optical fiber ferrule 21 of the optical fiber connector 2, thereby improving the reliability of the optical transmission system.

[0214] The present disclosure also provides an optical fiber ferrule cleaner 3, such as Fig. 20 and Fig.21 As shown, the optical fiber ferrule cleaner 3 includes a housing 11 and a discharge assembly 12. At least one end of the housing 11 has an interface 110 for docking with the optical fiber connector 2, and the housing 11 is used to accommodate the optical fiber ferrule 21 of the optical fiber connector 2. The discharge assembly 12 is connected to the housing 11, and the discharge assembly 12 is used to discharge inside the housing 11.

[0215] Among them, the optical fiber connector 2 connected to the optical fiber core cleaner 3 can be an LC optical fiber connector, FC optical fiber connector, SC optical fiber connector, ST optical fiber connector, MU optical fiber connector, MT optical fiber connector, DIN optical fiber connector or D4 optical fiber connector, etc.

[0216] The technical solution provided by the embodiment of the present disclosure is that when using the optical fiber ferrule cleaner 3, the optical fiber connector 2 is first docked with the optical fiber ferrule cleaner 3, and then the discharge component 12 is triggered to discharge, so as to clean the end face of the optical fiber ferrule 21 of the optical fiber connector 2. After that, the cleaned optical fiber connector 2 is docked with the optical fiber adapter 1, thereby improving the reliability of the optical transmission system.

[0217] In addition, compared with dustproof paper and dustproof cloth, the optical fiber ferrule cleaner 3 provided in the embodiment of the present disclosure will not scratch the end face of the optical fiber ferrule 21, and it is not easy to transfer dirt on the end face of the ferrule 211 to the end face of the optical fiber 212, thereby improving the cleaning effect of the end face of the optical fiber 212. In addition, the optical fiber ferrule cleaner 3 is non-disposable, has a low cost, and can be used in a wider range of scenarios.

[0218] The embodiment of the present disclosure does not specifically limit the discharge voltage of the discharge component 12, as long as it can clean the end face of the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is greater than 1 kV. In addition, the discharge voltage of the discharge component 12 should not be too high to avoid damaging the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is less than 12 kV. In other examples, in order to further reduce the possibility of damage to the optical fiber ferrule 21, the discharge voltage of the discharge component 12 is less than 5 kV.

[0219] Below, the implementation of the discharge component 12 is exemplified. In some examples, such as Figure 22-Figure 25 As shown, the discharge assembly 12 includes a power supply 121, a first electrode 122 and a second electrode 123. The power supply 121 is electrically connected to the first electrode 122 and the second electrode 123. The first electrode 122 and the second electrode 123 are located inside the housing 11 and face each other, and the first electrode 122 and the second electrode 123 are used for discharge.

[0220] The opposite ends of the first electrode 122 and the second electrode 123 are sharp. The first electrode 122 and the second electrode 123 may be needle-shaped electrodes. When the power supply 121 supplies power to the first electrode 122 and the second electrode 123, the first electrode 122 and the second electrode 123 generate instantaneous high voltage and break through the air between the first electrode 122 and the second electrode 123, so that an arc is generated between the first electrode 122 and the second electrode 123, and the arc can clean the end face of the optical fiber ferrule 21.

[0221] In some examples, such as Figure 22-Figure 25 As shown, the first electrode 122 and the second electrode 123 are coaxially arranged, and the line between the first electrode 122 and the second electrode 123 intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the end face of the optical fiber 212, thereby improving the cleaning effect of the end face of the optical fiber 212.

[0222] In some examples, such as Figure 22-Figure 25 As shown, the discharge assembly 12 further includes a wire 126, and the power source 121 is electrically connected to the first electrode 122 and the second electrode 123 via the wire 126. In which, illustratively, the wire 126 is embedded inside the housing 11.

[0223] Next, the positions of the first electrode 122 and the second electrode 123 are described in more detail.

[0224] In some examples, such as Figure 22-Figure 25As shown, the optical fiber ferrule cleaner 3 further includes a sleeve 13. The sleeve 13 is located inside the housing 11 and is used to accommodate the optical fiber ferrule 21. The first electrode 122 and the second electrode 123 are located on both sides of the sleeve 13, and the first electrode 122 and the second electrode 123 are used to discharge inside the sleeve 13.

[0225] The sleeve 13 is used to accommodate the optical fiber ferrule 21 of the optical fiber connector 2 . By discharging the first electrode 122 and the second electrode 123 inside the sleeve 13 , the optical fiber ferrule 21 can be cleaned.

[0226] In some examples, the line between the first electrode 122 and the second electrode 123 intersects with the central axis of the sleeve 13, wherein the central axis of the sleeve 13 is collinear with the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the center of the end face of the optical fiber ferrule 21, that is, through the end face of the optical fiber 212.

[0227] In some examples, such as Figure 22-Figure 25 As shown, the wall of the sleeve 13 is provided with a first opening 131 and a second opening 132 opposite to each other. The first electrode 122 extends into the first opening 131, and the second electrode 123 extends into the second opening 132. In this way, it is convenient for the first electrode 122 and the second electrode 123 to break through the air between the first electrode 122 and the second electrode 123 when they discharge.

[0228] In some examples, the first electrode 122 and the second electrode 123 are retracted relative to the inner wall of the sleeve 13 .

[0229] In some examples, such as Figure 22-Figure 25 As shown, the optical fiber ferrule cleaner 3 further includes a connector 14, and the sleeve 13 is connected to the housing 11 through the connector 14. The first electrode 122 and the second electrode 123 are fixed inside the connector 14. In this way, the first electrode 122 and the second electrode 123 are hidden inside the connector 14, reducing the possibility of damage to the first electrode 122 and the second electrode 123.

[0230] The embodiment of the present disclosure does not limit the type of the power source 121. In some examples, the power source 121 is a battery, and the discharge of the first electrode 122 and the second electrode 123 can be controlled by controlling the corresponding switch of the power source 121. Exemplarily, the battery can be disposed outside the housing 11 and electrically connected to the first electrode 122 and the second electrode 123 through an external wire.

[0231] In other examples, the power source 121 is a piezoelectric power source, and by applying pressure to the power source 121 (or referred to as striking the power source 121), the discharge of the first electrode 122 and the second electrode 123 can be controlled. The piezoelectric power source can be a piezoelectric ceramic or other piezoelectric material. The first electrode 122 and the second electrode 123 are respectively connected to the two sides of the power source 121. When the power source 121 is struck, a pressure difference is generated on both sides of the power source 121 and transmitted to the first electrode 122 and the second electrode 123, so that the first electrode 122 and the second electrode 123 generate high-voltage discharge.

[0232] Below, taking the power source 121 as a piezoelectric power source as an example, the triggering method of the discharge of the discharge component 12 is described. In some examples, during the docking process between the optical fiber connector 2 and the optical fiber ferrule cleaner 3, the optical fiber connector 2 applies pressure to the power source 121 and automatically triggers the discharge of the discharge component 12. In other examples, the discharge of the discharge component 12 can also be manually triggered by the user. Below, three triggering methods of the discharge component 12 are provided, among which the first two triggering methods are automatic triggering methods, and the third triggering method is a manual triggering method.

[0233] (1) Fig. 22 and Fig.23 As shown, the housing 11 has a snap-in slot 111 inside, which is used to snap-in with the snap-in 221 of the elastic arm 22 of the optical fiber connector 2. The power supply 121 is located in the snap-in slot 111, and the snap-in 221 is used to apply pressure to the power supply 121 when snap-in with the snap-in slot 111.

[0234] This solution is applicable to a scenario where the optical fiber connector 2 to which the optical fiber ferrule cleaner 3 is connected has an elastic arm 22 , for example, a scenario where the optical fiber connector 2 is an LC type optical fiber connector.

[0235] According to the technical solution provided by the embodiment of the present disclosure, during the docking process between the optical fiber connector 2 and the optical fiber ferrule cleaner 3, the elastic arm 22 is squeezed by the inner wall of the housing 11, and when the buckle 221 moves to the clamping groove 111, the buckle 221 loses its obstruction, and the elastic arm 22 extends, and the buckle 221 extends into the clamping groove 111, and hits the power supply 121 in the clamping groove 111, so that the discharge component 12 discharges. It can be seen that by setting the power supply 121 in the clamping groove 111, during the docking process between the optical fiber ferrule cleaner 3 and the optical fiber connector 2, the buckle 221 of the optical fiber connector 2 will automatically trigger the discharge of the discharge component 12 and complete the cleaning of the end face of the optical fiber ferrule 21, and the user does not need to perform extra operations, and the operation is simple.

[0236] In some examples, the elastic arm 22 of the optical fiber connector 2 has buckles 221 on both sides, and accordingly, the optical fiber ferrule cleaner 3 may have two snap-fitting grooves 111 and two power supplies 121 , and the two power supplies 121 are respectively located in the two snap-fitting grooves 111 .

[0237] In order to increase the pressure applied by the buckle 221 to the power source 121 and increase the striking speed, in some examples, such as Fig.23 As shown, the inner wall of the housing 11 has a protrusion 112, which is located on the docking path of the elastic arm 22 of the optical fiber connector 2 and in front of the clamping groove 111. In this way, during the docking process between the optical fiber connector 2 and the optical fiber ferrule cleaner 3, the elastic arm 22 of the optical fiber connector 2 is first squeezed by the protrusion 112 and stores energy, and then, when the buckle 221 reaches the clamping groove 111, the elastic arm 22 rebounds and drives the buckle 221 to hit the power source 121.

[0238] In some examples, such as Fig.23 As shown, in order to ensure smooth docking of the optical fiber connector 2, the side of the protrusion 112 that contacts the elastic arm 22 is a first inclined surface 1120, and the height of the first inclined surface 1120 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the first inclined surface 1120 protruding from the inner wall of the housing 11 gradually increases.

[0239] (2) Fig.24 As shown, the discharge assembly 12 further includes a first trigger member 124. The first trigger member 124 is movably connected to the housing 11 and is located on the docking path of the optical fiber connector 2. The power source 121 is located on the movable path of the first trigger member 124. During the docking process between the optical fiber connector 2 and the optical fiber ferrule cleaner 3, the optical fiber connector 2 drives the first trigger member 124 to apply pressure to the power source 121.

[0240] According to the technical solution provided by the embodiment of the present disclosure, during the docking process between the optical fiber connector 2 and the optical fiber ferrule cleaner 3, since the first trigger member 124 is located on the docking path of the optical fiber connector 2, the optical fiber connector 2 will contact the first trigger member 124 and drive the first trigger member 124 to move. Since the power supply 121 is located on the active path of the first trigger member 124, the first trigger member 124 will apply pressure to the power supply 121 and cause the discharge component 12 to discharge. It can be seen that the design of the above-mentioned first trigger member 124 enables the discharge component 12 to automatically discharge and clean the end face of the optical fiber ferrule 21 during the docking process between the optical fiber ferrule cleaner 3 and the optical fiber connector 2, and the user does not need to perform extra operations, and the operation is simple.

[0241] In some examples, such as Fig.24 As shown, the first trigger member 124 is located on the inner wall of the housing 11 and can be retracted relative to the inner wall of the housing 11. The power source 121 is located on the retractable path of the first trigger member 124.

[0242] In some examples, such as Fig.24As shown, in order to improve the smoothness of the docking of the optical fiber connector 2, the first trigger member 124 has a second inclined surface 1240, and the height of the second inclined surface 1240 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the second inclined surface 1240 protruding from the inner wall of the housing 11 gradually increases.

[0243] (3) Fig.25 As shown, the discharge assembly 12 further includes a second trigger member 125. The second trigger member 125 is movably connected to the housing 11 and exposed outside the housing 11. The power source 121 is located on the movable path of the second trigger member 125, and the second trigger member 125 is used to apply pressure to the power source 121 under the operation of the user.

[0244] When the optical fiber ferrule cleaner 3 is used, the optical fiber ferrule cleaner 3 is first connected to the optical fiber connector 2 , and then the second triggering member 125 is operated to trigger the discharge assembly 12 to discharge.

[0245] In some examples, such as Fig.25 As shown, the second trigger member 125 is a pressing member, and the user can apply pressure to the power source 121 by pressing the second trigger member 125, and discharge the first electrode 122 and the second electrode 123. Wherein, illustratively, the second trigger member 125 is slidably connected to the housing 11, and the power source 121 is located on the sliding path of the second trigger member 125. For example, the power source 121 is opposite to the bottom end of the second trigger member 125.

[0246] It should be noted that the optical fiber ferrule cleaner 3 provided in the embodiment of the present disclosure can also adopt the structure of the optical fiber adapter 1, that is, the optical fiber adapter 1 can also be used as the optical fiber ferrule cleaner 3 to clean the end face of the optical fiber ferrule 21. The specific structure of the optical fiber ferrule cleaner 3 can also refer to the relevant content of the aforementioned optical fiber adapter 1, which will not be repeated here.

[0247] The present disclosure also provides an optical device, such as Fig.26 and Fig. 27 As shown, the optical device has an interface component, which includes a housing 11 and a discharge assembly 12. The housing 11 has an interface 110 for docking the optical fiber connector 2. The discharge assembly 12 is fixed to the housing 11, and the discharge assembly 12 is used to discharge inside the housing 11 to clean the end face of the optical fiber ferrule 21.

[0248] The optical device provided in the embodiment of the present disclosure may be any device having an interface component for docking the optical fiber connector 2. For example, the optical device is an optical communication module (such as Fig. 27 As shown), optical instruments (such as spectrometers), passive optical function modules (such as optical switches and comb filters), optical amplifiers and fiber optic junction boxes (such as Fig.26 The optical fiber connector 2 connected to the interface component of the optical device can be an LC optical fiber connector, an FC optical fiber connector, an SC optical fiber connector, an ST optical fiber connector, an MU optical fiber connector, an MT optical fiber connector, a DIN optical fiber connector or a D4 optical fiber connector.

[0249] The technical solution provided by the embodiment of the present disclosure is that a discharge component 12 for discharging inside a shell 11 is arranged in the interface component of the optical device, so that during the process of docking the interface component of the optical device with the optical fiber connector 2, the discharge of the discharge component 12 can be triggered to clean the end face of the optical fiber ferrule 21 of the optical fiber connector 2, thereby improving the cleanliness of the end face of the optical fiber ferrule 21 and improving the reliability of the optical transmission system.

[0250] In some examples, the interface component provided by the embodiments of the present disclosure is the above-mentioned optical fiber adapter 1. For example, Fig.26 As shown, in the case where the optical device is a fiber optic junction box, the fiber optic junction box includes a box body 4 and a plurality of fiber optic adapters 1 (i.e., an interface component), and the plurality of fiber optic adapters 1 are fixed to the box body 4. In other examples, the interface component provided by the embodiments of the present disclosure is not the above-mentioned fiber optic adapter 1, but has a partial structure of the above-mentioned fiber optic adapter 1. For example, Fig. 27 As shown, in the case where the optical device is an optical communication module, the optical communication module does not have an independent optical fiber adapter 1, but also has a housing 11 for docking the optical fiber connector 2 and a discharge assembly 12 for discharging. Therefore, the specific structure of the interface component of the optical device provided by the embodiment of the present disclosure can refer to the relevant structure shown in the drawings of the aforementioned optical fiber adapter 1, and of course, can also refer to the relevant structure shown in the drawings of the aforementioned optical fiber core cleaner 3.

[0251] The embodiment of the present disclosure does not specifically limit the discharge voltage of the discharge component 12, as long as it can clean the end face of the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is greater than 1 kV. In addition, the discharge voltage of the discharge component 12 should not be too high to avoid damaging the optical fiber ferrule 21. In some examples, the discharge voltage of the discharge component 12 is less than 12 kV. In other examples, in order to further reduce the possibility of damage to the optical fiber ferrule 21, the discharge voltage of the discharge component 12 is less than 5 kV.

[0252] Below, the implementation of the discharge assembly 12 is exemplified. In some examples, please refer to Figure 5 , Fig. 9 and Figure 11-Figure 19The discharge assembly 12 includes a power supply 121, a first electrode 122, and a second electrode 123. The power supply 121 is electrically connected to the first electrode 122 and the second electrode 123. The first electrode 122 and the second electrode 123 are located inside the housing 11 and face each other, and the first electrode 122 and the second electrode 123 are used for discharge.

[0253] The opposite ends of the first electrode 122 and the second electrode 123 are sharp. The first electrode 122 and the second electrode 123 may be needle-shaped electrodes. When the power supply 121 supplies power to the first electrode 122 and the second electrode 123, the first electrode 122 and the second electrode 123 generate instantaneous high voltage and break through the air between the first electrode 122 and the second electrode 123, so that an arc is generated between the first electrode 122 and the second electrode 123, and the arc can clean the end face of the optical fiber ferrule 21.

[0254] For some examples, see Figure 5 , Fig. 9 , Fig.11 , Figure 13-Figure 15 , Fig.17 and Fig.18 The first electrode 122 and the second electrode 123 are coaxially arranged, and the line between the first electrode 122 and the second electrode 123 intersects and is perpendicular to the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the end face of the optical fiber 212, thereby improving the cleaning effect of the end face of the optical fiber 212.

[0255] For some examples, see Figure 5 , Fig. 9 and Figure 11-Figure 19 The discharge assembly 12 further includes a wire 126, and the power source 121 is electrically connected to the first electrode 122 and the second electrode 123 via the wire 126. In an exemplary embodiment, the wire 126 is embedded in the housing 11.

[0256] In some examples, the interface component of the optical device provided by the embodiment of the present disclosure further has an optical fiber ferrule, which is used to dock with the optical fiber ferrule of the optical fiber connector 2. Fig. 27 A scene showing an optical communication module.

[0257] In some examples, after the optical fiber ferrule 21 of the optical fiber connector 2 reaches the docking position, the optical fiber ferrule 21 of the optical fiber connector 2 will be in close contact with the optical fiber ferrule of the optical fiber adapter 1. Therefore, in order to clean the end surface of the optical fiber ferrule 21, the discharge group 12 is set to discharge before the optical fiber ferrule 21 of the optical fiber connector 2 reaches the docking position.

[0258] For some examples, see Figure 5 , Fig. 9, Fig.11 , Figure 13-Figure 15 , Fig.17 and Fig.18 The first electrode 122 and the second electrode 123 are opposite to the butt joint position of the optical fiber ferrule 21 of the optical fiber connector 2 and the optical fiber ferrule of the interface component. Alternatively, it is understood that the connection line of the first electrode 122 and the second electrode 123 passes through the butt joint position of the two optical fiber ferrules.

[0259] Next, the positions of the first electrode 122 and the second electrode 123 are described in more detail.

[0260] For some examples, see Figure 5 , Fig. 9 and Figure 11-Figure 19 The interface component of the optical device further includes a sleeve 13. The sleeve 13 is located inside the housing 11 and is used to accommodate the optical fiber ferrule 21. The first electrode 122 and the second electrode 123 are located on both sides of the sleeve 13, and the first electrode 122 and the second electrode 123 are used to discharge inside the sleeve 13.

[0261] The sleeve 13 is used to accommodate the optical fiber ferrule 21 of the optical fiber connector 2 . By discharging the first electrode 122 and the second electrode 123 inside the sleeve 13 , the optical fiber ferrule 21 can be cleaned.

[0262] In some examples, the optical fiber ferrule of the interface component of the optical device extends into the interior of the sleeve 13 .

[0263] In some examples, the line between the first electrode 122 and the second electrode 123 intersects with the central axis of the sleeve 13, wherein the central axis of the sleeve 13 is collinear with the central axis of the end face of the optical fiber ferrule 21. In this way, the arc generated between the first electrode 122 and the second electrode 123 can pass through the center of the end face of the optical fiber ferrule 21, that is, through the end face of the optical fiber 212.

[0264] For some examples, see Figure 5 , Fig. 9 and Figure 11-Figure 19 The wall of the sleeve 13 is provided with a first opening 131 and a second opening 132 opposite to each other. The first electrode 122 extends into the first opening 131, and the second electrode 123 extends into the second opening 132. In this way, when the first electrode 122 and the second electrode 123 discharge, the air between the first electrode 122 and the second electrode 123 is broken through.

[0265] For some examples, see Figure 5 , Fig. 9 and Figure 11-Figure 19 , the first electrode 122 and the second electrode 123 retract relative to the inner wall of the sleeve 13 .

[0266] For some examples, see Figure 5 , Fig. 9 and Figure 11-Figure 19 The interface component of the optical device further includes a connector 14, through which the sleeve 13 is connected to the housing 11. The first electrode 122 and the second electrode 123 are fixed inside the connector 14. In this way, the first electrode 122 and the second electrode 123 are hidden inside the connector 14, which reduces the possibility of damage to the first electrode 122 and the second electrode 123.

[0267] The embodiment of the present disclosure does not limit the type of the power source 121. In some examples, the power source 121 is a battery, and the discharge of the first electrode 122 and the second electrode 123 can be controlled by controlling the corresponding switch of the power source 121. Exemplarily, the battery can be arranged outside the housing 11 and electrically connected to the first electrode 122 and the second electrode 123 through an external wire. The battery can be a power supply for the optical device.

[0268] In other examples, the power source 121 is a piezoelectric power source, and by applying pressure to the power source 121 (or referred to as striking the power source 121), the discharge of the first electrode 122 and the second electrode 123 can be controlled. The piezoelectric power source can be a piezoelectric ceramic or other piezoelectric material. The first electrode 122 and the second electrode 123 are respectively connected to the two sides of the power source 121. When the power source 121 is struck, a pressure difference is generated on both sides of the power source 121 and transmitted to the first electrode 122 and the second electrode 123, so that the first electrode 122 and the second electrode 123 generate high-voltage discharge.

[0269] In the following, the power source 121 is taken as a piezoelectric power source as an example to explain the triggering mode of the discharge of the discharge component 12. In some examples, during the docking process between the optical fiber connector 2 and the interface component of the optical device, the optical fiber connector 2 applies pressure to the power source 121 and automatically triggers the discharge of the discharge component 12. In other examples, the discharge of the discharge component 12 can also be manually triggered by the user. In the following, three triggering modes of the discharge component 12 are provided, wherein the first two triggering modes are automatic triggering modes, and the third triggering mode is a manual triggering mode.

[0270] (1) Please see Figure 5-Figure 12 The housing 11 has a snap-in slot 111 inside, and the snap-in slot 111 is used to snap-in with the snap-in 221 of the elastic arm 22 of the optical fiber connector 2. The power supply 121 is located in the snap-in slot 111, and the snap-in 221 is used to apply pressure to the power supply 121 when snap-in with the snap-in slot 111.

[0271] This solution is applicable to a scenario where the optical fiber connector 2 to which the interface component of the optical device is connected has an elastic arm 22, for example, a scenario where the optical fiber connector 2 is an LC type optical fiber connector.

[0272] According to the technical solution provided by the embodiment of the present disclosure, during the docking process between the optical fiber connector 2 and the interface component of the optical device, the elastic arm 22 is squeezed by the inner wall of the housing 11, and when the buckle 221 moves to the clamping groove 111, the buckle 221 loses its obstruction, and the elastic arm 22 extends, and the buckle 221 extends into the clamping groove 111, and hits the power supply 121 in the clamping groove 111, so that the discharge component 12 discharges. It can be seen that by setting the power supply 121 in the clamping groove 111, during the docking process between the interface component of the optical device and the optical fiber connector 2, the buckle 221 of the optical fiber connector 2 will automatically trigger the discharge of the discharge component 12, and complete the cleaning of the end face of the optical fiber ferrule 21, and the user does not need to perform extra operations, and the operation is simple.

[0273] In some examples, the elastic arm 22 of the optical fiber connector 2 has buckles 221 on both sides, and accordingly, the interface component of the optical device can have two snap-in slots 111 and two power supplies 121, and the two power supplies 121 are respectively located in the two snap-in slots 111.

[0274] In order to increase the pressure applied by the buckle 221 to the power source 121 and increase the striking speed, in some examples, the inner wall of the housing 11 has a protrusion 112, which is located on the docking path of the elastic arm 22 of the optical fiber connector 2 and in front of the engaging groove 111. In this way, during the docking process between the optical fiber connector 2 and the interface component of the optical device, the elastic arm 22 of the optical fiber connector 2 is first squeezed by the protrusion 112 and stores energy, and then, when the buckle 221 reaches the engaging groove 111, the elastic arm 22 rebounds and drives the buckle 221 to strike the power source 121.

[0275] For some examples, see Fig.23 In order to ensure smooth docking of the optical fiber connector 2, the side of the protrusion 112 that contacts the elastic arm 22 is a first inclined surface 1120, and the height of the first inclined surface 1120 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the first inclined surface 1120 protruding from the inner wall of the housing 11 gradually increases.

[0276] (2) Please see Figure 13-Figure 16 The discharge assembly 12 further includes a first trigger member 124. The first trigger member 124 is movably connected to the housing 11 and is located on the docking path of the optical fiber connector 2. The power source 121 is located on the movable path of the first trigger member 124. During the docking process between the optical fiber connector 2 and the interface component of the optical device, the optical fiber connector 2 drives the first trigger member 124 to apply pressure to the power source 121.

[0277] According to the technical solution provided by the embodiment of the present disclosure, during the docking process between the optical fiber connector 2 and the interface component of the optical device, since the first trigger member 124 is located on the docking path of the optical fiber connector 2, the optical fiber connector 2 will contact the first trigger member 124 and drive the first trigger member 124 to move. Since the power supply 121 is located on the active path of the first trigger member 124, the first trigger member 124 will apply pressure to the power supply 121 and cause the discharge component 12 to discharge. It can be seen that the design of the above-mentioned first trigger member 124 enables the discharge component 12 to automatically discharge and clean the end face of the optical fiber ferrule 21 during the docking process between the interface component of the optical device and the optical fiber connector 2, and the user does not need to perform extra operations, and the operation is simple.

[0278] For some examples, see Figure 13-Figure 16 The first trigger member 124 is located on the inner wall of the housing 11 and can be extended and retracted relative to the inner wall of the housing 11. The power source 121 is located on the extension path of the first trigger member 124.

[0279] For some examples, see Figure 13-Figure 16 In order to improve the smoothness of the docking of the optical fiber connector 2, the first trigger member 124 has a second inclined surface 1240, and the height of the second inclined surface 1240 gradually increases along the docking direction of the optical fiber connector 2. Alternatively, it can also be understood that along the docking direction of the optical fiber connector 2, the height of the second inclined surface 1240 protruding from the inner wall of the housing 11 gradually increases.

[0280] (3) Please see Figure 17-Figure 19 The discharge assembly 12 further includes a second trigger member 125. The second trigger member 125 is movably connected to the housing 11 and exposed outside the housing 11. The power source 121 is located on the movable path of the second trigger member 125, and the second trigger member 125 is used to apply pressure to the power source 121 under the operation of the user.

[0281] The technical solution provided by the embodiment of the present disclosure, by providing a second triggering member 125 operated by the user, enables the user to independently select the time for the discharge assembly 12 to discharge, without having to discharge the discharge assembly 12 every time the interface component of the optical device is docked with the optical fiber connector 2. For example, when the user observes that the end face of the optical fiber ferrule 21 of the optical fiber connector 2 is clean enough, there is no need to operate the second triggering member 125 to trigger the discharge assembly 12 to discharge, thereby increasing the life of the discharge assembly 12.

[0282] For some examples, see Figure 17-Figure 19, the second trigger member 125 is a pressing member, and the user can apply pressure to the power source 121 by pressing the second trigger member 125, and discharge the first electrode 122 and the second electrode 123. Wherein, illustratively, the second trigger member 125 is slidably connected to the housing 11, and the power source 121 is located on the sliding path of the second trigger member 125. For example, the power source 121 is opposite to the bottom end of the second trigger member 125.
