Description

Technical Field

[0001] The present application relates to the field of optical fiber connection technology, and in particular to an adapter, an optical fiber connector, an optical fiber connector assembly and a communication device. Background Art

[0002] In a communication system, the signal transmission between signal devices is achieved by connecting two or more segments of optical fiber. Usually, two optical fiber connectors are inserted into an adapter, and the two optical fiber connectors are fixed by the adapter to achieve stable connection of the two optical fiber connectors. As the demand for bandwidth in data centers continues to increase, the requirements for optical fiber connection density continue to increase. It is necessary to increase the number of optical connections to transmit more data in a given space, that is, to set up more optical fiber connectors in the same footprint to provide backward compatibility with existing data center equipment, thereby improving service quality and reducing costs.

[0003] In the prior art, the locking of the optical fiber connector and the adapter is achieved through the cooperation of the buckle and the slot. During the unlocking process, the operator is required to insert a finger or a tool into the slot and press the buckle to release the cooperation between the buckle and the slot. This unlocking method requires increasing the setting distance of the optical fiber connector, which is not conducive to the high-density arrangement of the optical fiber connector.

The slider is used to move relative to the first shell under the thrust of the optical fiber connector. The slider includes a block body, a hook arranged on the block body, and a limiting portion arranged on the block body, and the second end cooperates with the block body; the block body is used to move under the push of the optical fiber connector, so that after relative movement with the pull rod, the second end abuts against the limiting portion so that the hook can be clamped and fixed with the slot on the optical fiber connector; the block body is also used to continue to move under the push of the optical fiber connector, so that after relative movement with the pull rod, the second end releases the abutment with the limiting portion so that the hook can be disengaged from the slot on the optical fiber connector. In the present application, the optical fiber connector and the adapter can be locked or unlocked by only pushing the optical fiber connector, which reduces the operating space required for the installation and removal of the optical fiber connector and the adapter, and is conducive to improving the arrangement density of the optical fiber connector in a limited space, thereby improving the integration of the optical fiber connector assembly and the bandwidth of the communication equipment and the communication system. The optical fiber connector assembly is locked or unlocked by the relative movement between the slider and the pull rod, which is conducive to simplifying the structure of the adapter, thereby helping to reduce the size of the adapter, so as to further improve the bandwidth of the communication equipment and the communication system.

In the process of unlocking the adapter and the optical fiber connector, the second end can move along the second groove body in a direction away from the limit portion, so that the pull rod and the slider are released, so that the slider moves along the first direction to the outside of the accommodating cavity, thereby facilitating the unlocking of the adapter and the optical fiber connector, so as to reduce the difficulty of unlocking the adapter and the optical fiber connector.

[0010] In some embodiments, the slide is provided with a second limiting step, and along the first direction, the second limiting step is located on the side of the first protrusion away from the first limiting surface, and the second end can abut against the side wall of the second limiting step and move along the second limiting step toward the direction close to the first slot body; and / or, the slide is provided with a third limiting step, and the third limiting step is located between the first protrusion and the first limiting surface, and the second end can abut against the third limiting step to limit the second end from moving along the limiting portion toward the direction close to the first slot body.

In the present application, the second limit surface can reduce the risk of damage to the slider, the pull rod or the first shell due to the large movement distance of the slider, which is beneficial to prolong the service life of the adapter and improve the working stability of the adapter. The second limit surface and the limit portion are staggered in the second direction, which reduces the risk of the second end abutting against the limit portion again and causing the unlocking failure, improves the accuracy of the unlocking of the pull rod and the slider, and thus reduces the difficulty of unlocking the adapter and the optical fiber connector.

[0012] In some embodiments, the slide groove is provided with a fourth limiting step, and along the first direction, the fourth limiting step is arranged opposite to the first guide surface, and the second end can abut against the fourth limiting step to limit the second end from moving along the first guide surface in a direction away from the second limiting surface. In the present application, the fourth limiting step is provided to reduce the risk that the second end cannot enter the second groove body, resulting in the rod and the slider being unable to be unlocked, thereby improving the accuracy of the movement direction of the second end, and further reducing the difficulty of unlocking the rod and the slider.

[0014] In some embodiments, the locking module further includes a first elastic member, one end of the first elastic member is connected to the first shell, the other end of the first elastic member is connected to the block body, and the first elastic member can drive the slider to move in a direction away from the pull rod. In the present application, the first elastic member is provided to simplify the operation of locking and unlocking the adapter and the optical fiber connector, reduce the difficulty of operation during the locking and unlocking process, and help reduce the operating space required during the locking and unlocking process of the adapter and the optical fiber connector, thereby helping to increase the arrangement density of the adapter and the optical fiber connector.

In the process of the movement of the slider, the movement of the hook in the third direction Y is achieved by the deformation or change of the cantilever, which reduces the difficulty of the hook moving in a direction close to or away from the optical fiber connector, and helps to simplify the structure of the slider.

[0016] The second aspect of the present application provides a fiber optic connector, which includes a housing and a core connection assembly installed on the housing, and the housing is provided with a slot, which is used to engage with a hook on a locking module to limit the movement of the fiber optic connector relative to the locking module. In the present application, the fiber optic connector and the adapter can be locked or unlocked by the movement of the fiber optic connector in the first direction, which simplifies the locking and unlocking operations of the fiber optic connector and the adapter, and reduces the operating space required for the installation and removal of the fiber optic connector and the adapter, which is conducive to improving the arrangement density of the fiber optic connector in the limited space, and further helps to improve the integration of the fiber optic connector assembly, so as to improve the bandwidth of the communication equipment and the communication system. The fiber optic connector assembly is locked or unlocked by the relative movement between the slider and the pull rod, which is conducive to simplifying the structure of the adapter, thereby helping to reduce the size of the adapter, so as to increase the number of fiber optic connector assemblies set in the limited space, so as to further improve the bandwidth of the communication equipment and the communication system.

The outer shell and the inner shell are fixed by snapping the snap-fitting portion and the snap-fitting portion, which is conducive to reducing the size of the outer shell and the inner shell, and then it is conducive to reducing the overall size of the optical fiber connector, so as to further improve the arrangement density of the optical fiber connector. When the snap-fitting portion is arranged on both sides of the inner shell, the outer shell can be installed forward or reversely according to the connection needs, so as to facilitate the replacement of the docking polarity of the optical fiber connector, thereby improving the scope of application of the optical fiber connector.

In the present application, the ferrule is an LC ferrule or an MT ferrule, which increases the types of ferrules that can be selected, which is beneficial to improving the scope of application of the optical fiber connector. Among them, when the ferrule is an LC ferrule, the cost of the optical fiber connector is reduced, and it is beneficial to reduce the overall size of the optical fiber connector, so as to improve the arrangement density of the optical fiber connector.

In addition, the LC ferrule can improve durability and reduce the rearrangement work caused by cross-connection. When the ferrule is an MT ferrule, the density of the optical fiber connection is improved, which is beneficial to further improve the bandwidth of communication equipment and communication systems.

[0098] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0099] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0100] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0101] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0102] In a first aspect, an embodiment of the present application provides a communication device, the communication device includes an adapter 01, and the adapter 01 is used to connect with an optical fiber connector 02 to form an optical fiber connector assembly, so as to facilitate the transmission of signals between the communication device and an external device. The communication device includes but is not limited to electronic devices with communication functions such as base stations, computers, telephones, televisions, or cars, and the embodiment of the present application does not impose any special restrictions on the specific types of communication devices.

[0103] A second aspect of the present application provides an optical fiber connector assembly, which is applied to a communication system to achieve signal transmission. Figure 1 As shown, the optical fiber connector assembly includes an adapter 01 and an optical fiber connector 02, the number of the optical fiber connectors 02 is at least two, one end of each optical fiber connector 02 is located in the adapter 01, so that two optical fiber connectors 02 distributed along a first direction X are connected to each other, wherein the number of the optical fiber connectors 02 can be two, or can be 4, 6, 8 or more, so as to improve the arrangement density of the optical fiber connectors 02. The first direction X is substantially parallel to the length direction of the optical fiber connector 02.

[0104] In one embodiment, the optical fiber connector 02 and the adapter 01 are fixedly and non-detachably connected to increase the connection stability between the optical fiber connector 02 and the adapter 01, thereby improving the working stability of the communication device and the communication system.

[0105] In another embodiment, the optical fiber connector 02 and the adapter 01 are detachably connected to facilitate operations such as installation, removal, replacement or repair of the optical fiber connector 02 .

[0106] When the optical fiber connector 02 and the adapter 01 are detachably connected, Figure 2As shown, the adapter 01 includes a first shell 1, the first shell 1 is provided with a receiving cavity 11, the receiving cavity 11 is distributed on both sides of the first shell 1 along a first direction X, and the first shell 1 is further provided with a first docking channel 15 and a second docking channel 16 arranged along a second direction Z. The second direction Z is perpendicular to the first direction X. For example, the second direction Z is parallel to the height direction of the optical fiber connector assembly, that is, Figure 2 As shown, the second direction Z is parallel to the height direction of the adapter 01, and the two accommodating cavities 11 distributed along the first direction X are connected through the first docking channel 15 and the second docking channel 16. A part of the optical fiber connector 02 can be inserted into the accommodating cavity 11, and the two optical fiber connectors 02 distributed in the first direction X are docked through the first docking channel 15 and the second docking channel 16 respectively.

[0107] like Figure 2 As shown, the adapter 01 also includes a locking module 2, which is installed in the first housing 1. The locking module 2 includes a pull rod 21 and a slider 22. One end of the pull rod 21 is connected to the first housing 1, and the other end of the pull rod 21 cooperates with the slider 22. The locking module 2 may also include a first elastic member 23, one end of the first elastic member 23 is connected to the first housing 1, and the other end of the first elastic member 23 is connected to the slider 22. Figure 3 As shown, the slider 22 can be provided with a slide groove 225 and a limit portion 223. One end of the pull rod 21 used to connect with the slider 22 is located in the slide groove 225. In one state, after the pull rod 21 slides, it can cooperate with the limit portion 223 to limit the slider 22, which will be described in detail below.

[0108] During the installation of the optical fiber connector 02, the operator inserts the optical fiber connector 02 into the first housing 1 along the first direction X. Along the first direction X, the slider 22 is used to move toward the inside of the accommodating cavity 11 under the thrust of the optical fiber connector 02, so that one end of the pull rod 21 moves along the slide groove 225 and bypasses the limit portion 223. As the slider 22 moves, the first elastic member 23 is stretched or compressed and generates a rebound force. When the operator cancels the drive on the slider 22, the slider 22 is used to move toward the outside of the accommodating cavity 11 under the action of the rebound force of the first elastic member 23, so that the pull rod 21 is engaged with the limit portion 223. Thereafter, the pull rod 21 can limit the slider 22 from moving away from the pull rod 21 along the first direction X, so that the slider 22 is locked with the first housing 1. At the same time, as Figure 3 As shown, the hook 222 on the slider 22 can be engaged and fixed with the mating part on the optical fiber connector 02, so that the optical fiber connector 02 and the slider 22 cannot move relative to each other in the first direction X, thereby achieving the locking of the slider 22 and the optical fiber connector 02, and further achieving the locking of the optical fiber connector 02 and the adapter 01.

[0109] When the optical fiber connector 02 needs to be disassembled, the optical fiber connector 02 is first pushed into the first housing 1 along the first direction X. The slider 22 moves into the accommodating cavity 11 along the first direction X under the push of the optical fiber connector 02, so that the pull rod 21 is released from the abutment with the limiting portion 223, so as to unlock the first housing 1 and the slider 22. As the slider 22 moves, the first elastic member 23 generates a rebound force. When the operator cancels the drive of the slider 22, the slider 22 moves toward the outside of the accommodating cavity 11 under the action of the rebound force of the first elastic member 23, so that the pull rod 21 moves along the slide groove 225, and the hook 222 is disengaged from the mating portion on the optical fiber connector 02, so as to unlock the slider 22 and the optical fiber connector 02, thereby realizing the unlocking of the optical fiber connector 02 and the adapter 01.

[0110] In this embodiment, the optical fiber connector 02 and the adapter 01 can be locked or unlocked by only pushing the optical fiber connector 02 along the first direction X, which simplifies the locking and unlocking operations of the optical fiber connector 02 and the adapter 01, and reduces the operating space required for the installation and removal of the optical fiber connector 02 and the adapter 01, thereby facilitating the improvement of the arrangement density of the optical fiber connector 02 in the limited space, thereby facilitating the improvement of the integration of the optical fiber connector assembly, so as to improve the bandwidth of the communication equipment and the communication system, and at the same time, reducing the difficulty of installing and removing the optical fiber connector 02 and the communication equipment, thereby reducing the time and operating space required for installation and removal. The locking or unlocking of the optical fiber connector assembly is achieved by the relative movement between the slider 22 and the pull rod 21, which is conducive to simplifying the structure of the adapter 01, thereby facilitating the reduction of the size of the adapter 01, so as to facilitate the increase of the number of optical fiber connector assemblies set in the limited space, thereby facilitating the further improvement of the bandwidth of the communication equipment and the communication system.

[0111] The relative movement of the optical fiber connector 02 and the adapter 01 in the first direction X is limited by the cooperation between the hook 222 and the mating part on the optical fiber connector 02, thereby reducing the risk of the two optical fiber connectors 02 distributed along the first direction X being separated along the first direction X during use, thereby improving the connection stability between the adapter 01 and the optical fiber connector 02, and improving the accuracy and stability of the docking of the two optical fiber connectors 02 distributed along the first direction X, so as to improve the working stability and reliability of the communication equipment and the communication system.

[0112] The first elastic member 23 is provided to simplify the locking and unlocking operations of the adapter 01 and the optical fiber connector 02, thereby reducing the difficulty of the locking and unlocking operations, and is conducive to reducing the operating space required for the locking and unlocking operations of the adapter 01 and the optical fiber connector 02, thereby facilitating the improvement of the arrangement density of the adapter 01 and the optical fiber connector 02. In the first direction X, the first elastic member 23 may be located on the side of the slider 22 close to the pull rod 21, or on the side of the slider 22 away from the pull rod.

[0113] Specifically, Figure 4 As shown, the projection shape of the pull rod 21 in the second direction Z is roughly a U-shaped structure, that is, the pull rod 21 includes a first end 211, a second end 212 and a rod body 213. Along the axial direction of the rod body 213, the first end 211 and the second end 212 are relatively arranged on both sides of the rod body 213, and the angle between the central axis of the first end 211 and the central axis of the rod body 213 is greater than 0°, and the angle between the central axis of the second end 212 and the central axis of the rod body 213 is greater than 0. Figure 5 As shown, a mounting groove 17 is provided on the side wall of the first housing 1, and at least a portion of the first end 211 is inserted into the mounting groove 17 along the third direction Y, so that the pull rod 21 is connected to the first housing 1, and the pull rod 21 can swing relative to the first housing 1, and at least a portion of the second end 212 is inserted into the slide groove 225 along the third direction Y, so as to facilitate the movement of the second end 212 in the slide groove 225. As mentioned above, the slider 22 and the pull rod 21 can move relative to each other. When the slider 22 moves along the first direction X, the first end of the pull rod 21 can be fixed in the mounting groove 17, and with the movement of the slider 22 and the swing of the pull rod 21, the second end of the pull rod 21 can slide in the slide groove 225, and then cooperate with the limiting portion 223 to limit.

[0114] In this embodiment, if Figure 4 As shown, the pull rod 21 is roughly U-shaped, which simplifies the structure of the pull rod 21 and also simplifies the connection method between the pull rod 21 and the first shell 1 and the pull rod 21 and the slider 22, thereby helping to reduce the space occupied by the pull rod 21 and the slider 22 in the accommodating cavity 11, and further helping to reduce the overall size of the adapter 01.

[0115] Among them, the extension direction of the first end 211 and the second end 212 is recorded as a third direction Y, and the third direction Y is perpendicular to the first direction X and the second direction Z. For example, the first direction X is the length direction of the adapter 01, and the second direction Z is the height direction of the adapter 01, and the third direction Y is the width direction of the adapter 01. The first end 211 and the second end 212 can be integrally formed with the rod body 213, and can also be fixedly connected by gluing, welding, etc. In this embodiment, the first end 211 and the second end 212 are formed by bending the rod body 213 along the third direction Z to improve the overall structural strength of the pull rod 21.

[0116] like Figure 5As shown, a second mounting post 14 is further provided on the first shell 1, one end of the first elastic member 23 is sleeved on the second mounting post 14, and the other end of the first elastic member 23 is sleeved on the mounting post on the slider, so as to simplify the mounting structure of the first elastic member 23, thereby helping to simplify the structure of the slider 22 and the first shell 1, and further helping to reduce the overall size of the adapter 01. At the same time, the risk of the first elastic member 23 separating from the slider 22 and the first shell 1 during stretching or contraction is reduced, thereby improving the connection stability of the first elastic member 23 with the slider 22 and the first shell 1.

[0117] like Figure 5 As shown, a second guide groove 13 is provided on the side wall of the first housing 1. Figure 6 As shown, the slider 22 includes a block body 221 and a guide portion 221c arranged on the block body 221, the guide portion 221c is located in the second guide groove 13, and when the slider 22 moves along the first direction X, the guide portion 221c can move along the second guide groove 13 to improve the stability of the moving direction of the slider 22.

[0118] like Figure 6 As shown, the slider 22 further includes a cantilever 221b, the cantilever 221b is connected to the block body 221, the hook 222 is arranged on the side of the cantilever 221b away from the block body 221, and a guide column 222a is arranged on the cantilever 221b and / or the hook 222; Figure 7 and Figure 8 As shown, a boss 18 protruding toward the optical fiber connector 02 along the third direction Y is further provided in the first shell 1. When the optical fiber connector 02 pushes the slider 22 to move in the accommodating cavity 11 along the first direction X, the cantilever 221b can be driven by the boss 18 to undergo local deformation in the direction close to the optical fiber connector 02 along the third direction Y, so that at least a portion of the hook 222 extends into the slot 31. A first guide groove 12 is also provided in the first shell 1. At least a portion of the guide column 222a is located in the first guide groove 12, and the guide column 222a can move along the side wall of the first guide groove 12.

[0119] When the slider 22 moves along the first direction X into the accommodating cavity 11, at least a portion of the cantilever 221b will be deformed or swing in the third direction Y under the push of the boss 18, so that the hook 222 moves in the third direction Y toward the optical fiber connector 02, thereby allowing the hook 222 to extend into the mating portion of the optical fiber connector 02 along the third direction Y, thereby completing the locking of the adapter 01 and the optical fiber connector 02; when the slider 22 moves along the first direction X out of the accommodating cavity 11, the cantilever 221b gradually separates from the boss 18, and the cantilever 221b will move along the third direction Y away from the optical fiber connector 02 under the action of its own rebound force until the hook 222 is disengaged from the mating portion of the optical fiber connector 02 in the third direction Y, so as to facilitate the removal of the optical fiber connector 02 from the adapter 01.

[0120] In this embodiment, the boss 18 is provided to achieve the locking or unlocking of the slider 22 and the optical fiber connector 02 during the movement of the slider 22, that is, in the process of locking or unlocking the optical fiber connector 02 and the adapter 01, it is only necessary to push or pull the slider 22, thereby simplifying the locking and unlocking operations of the slider 22 and the optical fiber connector 02, reducing the difficulty of locking or unlocking, and at the same time, helping to reduce the operating space required during the locking or unlocking process, so as to improve the arrangement density of the optical fiber connector 02 and the adapter 01. The hook 222 is connected to the block body 221 through the cantilever 221b. During the movement of the slider 22, the deformation or change of the cantilever 221b realizes the movement of the hook 222 in the third direction Y, reducing the difficulty of the hook 222 moving toward or away from the optical fiber connector 02, thereby helping to simplify the structure of the slider 22.

[0121] The first guide groove 12 is provided so that the hook 222 can slide along the side wall of the first guide groove 12 , thereby improving the accuracy of the movement direction of the hook 222 during the movement of the slider 22 , and further improving the working stability of the hook 222 .

[0122] The cantilever 221 b and the hook 222 are both located in the second guide groove 13 , and the first guide groove 12 is arranged on the side wall of the second guide groove 13 distributed along the second direction Z to simplify the structure of the first shell 1 .

[0123] In addition, the cantilever 221 b and the guide portion 221 c may be integrally formed to further simplify the structure of the slider 22 .

[0124] like Fig. 9As shown, the hook 222 and the slide groove 225 are both arranged on the block body 221. The block body 221 is used to move along the first direction X under the push of the optical fiber connector 02. A first mounting column 211e for mounting the first elastic member 23 is arranged on the block body 221, and in the first direction X, a third guide surface 222b extending obliquely is arranged on the side of the guide column 222a away from the block body 221. The third guide surface 222b can facilitate the installation or disassembly of the guide column 222a in the first guide groove 12, thereby reducing the risk of damage to the edge of the guide column 222a due to stress concentration during the installation or disassembly process, so as to extend the service life of the slider 22.

[0125] like Fig. 9 As shown, an inner cavity 221a is provided on the block body 221, and a first protrusion 224 is provided in the inner cavity 221a. Part of the side wall of the first protrusion 224 and part of the side wall of the inner cavity 221a form a slide groove 225; a part of the first protrusion 224 is recessed along the first direction X to form a limiting portion 223.

[0126] In this embodiment, the slide groove 225 can guide the relative movement of the slider 22 and the second end 212, reducing the risk of the second end 212 being separated from the slider 22 during the relative movement of the slider 22 and the second end 212, thereby improving the connection stability between the second end 212 and the slider 22, and further improving the working stability and reliability of the locking module 2. A raised first protrusion 224 is provided inside the slide groove 225, and a local depression of the first protrusion 224 forms a limiting portion 223, that is, the limiting portion 223 is a groove on the first protrusion 224, which simplifies the structure of the limiting portion 223 and the slider 22, thereby helping to reduce the overall size of the adapter 01, reducing the cost of the adapter 01, and helping to increase the number of adapters 01.

[0127] like Fig. 9 As shown, the slide groove 225 includes a first groove body 225a and a second groove body 225b, the first groove body 225a and the second groove body 225b are distributed on both sides of the first protrusion 224 along the second direction Z, and the first groove body 225a and the second groove body 225b are connected through the limiting portion 223.

[0128] like Fig. 9 As shown, the inner cavity 221a is further provided with a first limiting surface 226, which is arranged opposite to the limiting portion 223 along the first direction X. The second end 212 can abut against the first limiting surface 226 to limit the moving distance of the slider 22 in the first direction X.

[0129] When the optical fiber connector 02 pushes the slider 22 to move inside the adapter 01 along the first direction X, Fig.10As shown, the second end 212 of the pull rod 21 moves along the first groove 225a and bypasses the limiting portion 223 until the second end 212 abuts against the first limiting surface 226. Thereafter, the driving slider 22 moves along the first direction X to the outside of the adapter 01, so that the second end 212 abuts against the limiting portion 223, thereby locking the slider 22 and the pull rod 21.

[0130] like Fig. 9 As shown, a second protrusion 227 is further disposed in the inner cavity 221a. The second protrusion 227 and the first protrusion 224 are disposed opposite to each other along the first direction X. In addition, along the first direction X, the second protrusion 227 and the first limiting surface 226 are disposed on the same side of the first protrusion 224. Fig.11 and Fig.12 As shown, the second protrusion 227 is provided with a first guide surface 227a, and along the second direction Z, the first guide surface 227a and the first limiting surface 226 are relatively arranged on both sides of the second protrusion 227; the first guide surface 227a extends obliquely, and the inner cavity 221a is also provided with a second limiting surface 228, and along the second direction Z, the second limiting surface 228 is located on the side of the first guide surface 227a away from the first limiting surface 226, and the first guide surface 227a and the limiting portion 223 are staggered in the second direction Z; the second end 212 can abut against the first guide surface 227a, and the second end 212 can move along the first guide surface 227a in the direction close to the second limiting surface 228, so that the pull rod 21 enters the second groove body 225b.

[0131] During the unlocking process of the adapter 01 and the optical fiber connector 02, Fig.10 As shown, the driving slider 22 moves along the first direction X into the accommodating cavity 11, so that the second end 212 is released from the abutment with the limiting portion 223 and abuts against the first guide surface 227a. Thereafter, the second end 212 moves along the first guide surface 227a in a direction close to the second limiting surface 228 until it abuts against the second limiting surface 228. In view of the fact that the limiting portion 223 and the second limiting surface 228 are staggered along the second direction Z, the second limiting surface 228 and the second groove body 225b are arranged relative to each other in the second direction Z. When the driving slider 22 moves along the first direction X toward the outside of the accommodating cavity 11, the second end 212 can be released from the abutment with the second limiting surface 228 and enter the second groove body 225b. Thereafter, as the slider 22 moves in the first direction X, the second end 212 moves along the second groove body 225b in a direction away from the limiting portion 223 to achieve unlocking of the pull rod 21 and the slider 22.

[0132] In this embodiment, the first limiting surface 226 can limit the moving distance of the slider 22 in the first direction X, reducing the risk of damage to the pull rod 21, the slider 22 or the first housing 1 due to a large moving distance of the slider 22, thereby extending the service life of the adapter 01 and facilitating the improvement of the working stability and reliability of the adapter 01. The second limiting surface 228 can limit the moving distance of the slider 22 in the first direction X during the unlocking process, reducing the risk of damage to the slider 22, the pull rod 21 or the first housing 1 due to a large moving distance of the slider 22, thereby facilitating the improvement of the working stability of the adapter 01. The second limiting surface 228 and the limiting portion 223 are staggered along the second direction Z. After the second end 212 abuts against the second limiting surface 228, during the movement of the slider 22 along the first direction X toward the outside of the accommodating cavity 11, the second end 212 can avoid the limiting portion 223 and directly enter the second groove 225b, reducing the risk of the second end 212 abutting against the limiting portion 223 again and causing the unlocking to fail, thereby improving the unlocking accuracy of the pull rod 21 and the slider 22, and further reducing the unlocking difficulty of the adapter 01 and the optical fiber connector 02. The first guide surface 227a extending obliquely is provided to facilitate the movement of the second end 212 to abut against the second limiting surface 228, thereby reducing the difficulty of the second end 212 entering the second groove 225b, so as to simplify the structure of the slider 22.

[0133] Among them, Fig.12 As shown, the second protrusion 227 is also provided with a second guide surface 227b extending obliquely, and the second guide surface 227b and the first guide surface 227a are relatively arranged on both sides of the second protrusion 227 in the second direction Z, and in the second direction Z, the first limiting surface 226 is located on the side of the second guide surface 227b away from the first guide surface 227a. In the process of locking the adapter 01 and the optical fiber connector 02, after the second end 212 abuts against the first limiting surface 226, when the driving slider 22 moves toward the outside of the accommodating cavity 11 along the first direction X, the second end 212 can abut against the second guide surface 227b and be guided by the second guide surface 227b to the limiting portion 223, so as to facilitate the abutment of the second end 212 with the limiting portion 223, thereby reducing the difficulty of abutting the second end 212 with the limiting portion 223, and further reducing the difficulty of locking the slider 22 and the pull rod 21.

[0134] like Fig.11 and Fig.12 As shown, the slide groove 225 is provided with a first limiting step 225c, the first limiting step 225c is connected to the limiting portion 223, and the second end 212 can abut against the first limiting step 225c and move along the first limiting step 225c toward the limiting portion 223.

[0135] After the second end 212 abuts against the first limiting surface 226, during the movement of the slider 22 along the first direction X toward the outside of the adapter 01, the second end 212 releases the abutment with the first limiting surface 226 and moves in the direction close to the limiting portion 223. A first limiting step 225c is provided. During the movement of the second end 212 toward the limiting portion 223, if the moving path of the slider 22 deviates in the second direction Z, the second end 212 can abut against the first limiting step 225c and move along the first limiting step 225c, that is, the first limiting step 225c can guide the second end 212 to the limiting portion 223, thereby improving the accuracy of the movement direction of the slider 22, and further improving the accuracy and reliability of the cooperation between the second end 212 and the limiting portion 223 during the locking process of the adapter 01 and the optical fiber connector 02.

[0136] like Fig. 9 As shown, the first limiting step 225c is arranged on the first slot body 225a; the second end 212 can move along the first slot body 225a toward the limiting portion 223 to lock the adapter 01 and the optical fiber connector 02, and the second end 212 can move along the second slot body 225b toward the direction away from the limiting portion 223 to unlock the adapter 01 and the optical fiber connector 02.

[0137] During the process of locking the adapter 01 and the optical fiber connector 02, the second end 212 can move along the first groove body 225a. During this process, the second end 212 can cross the first limiting step 225c and abut against the first limiting surface 226. Thereafter, the second end 212 separates from the first limiting surface 226 and moves in the direction close to the second end 212. The second end 212 will directly abut against the limiting portion 223, or the second end 212 will abut against the first limiting step 225c and be guided by the first limiting step 225c to the limiting portion 223 until it abuts against the limiting position. In view of the fact that the first groove body 225a is provided with the first limiting step 225c, the second end 212 can move in the first groove 225a in the direction close to the limit portion 223, and it is difficult for the second end 212 to make a reverse movement in the first groove 225a. For this reason, a second groove 225b is provided in the present embodiment. During the unlocking process of the adapter 01 and the optical fiber connector 02, the second end 212 can move along the second groove 225b in the direction away from the limit portion 223, so that the pull rod 21 and the slider 22 are released from the engagement, so that the slider 22 can move along the first direction X to the outside of the accommodating cavity 11, thereby facilitating the unlocking of the adapter 01 and the optical fiber connector 02 and reducing the difficulty of unlocking the adapter 01 and the optical fiber connector 02.

[0138] like Fig.12As shown, the slide groove 225 is provided with a second limiting step 225d, and along the first direction X, the second limiting step 225d is located on the side of the first protrusion 224 away from the first limiting surface 226, and the second end 212 can abut against the side wall of the second limiting step 225d and move along the second limiting step 225d toward the direction close to the first groove body 225a; and / or, the slide groove 225 is provided with a third limiting step 225e, and the third limiting step 225e is located between the first protrusion 224 and the first limiting surface 226, and the second end 212 can abut against the third limiting step 225e to limit the second end 212 from moving along the limiting portion 223 toward the direction close to the first groove body 225a.

[0139] During the locking process of the adapter 01 and the optical fiber connector 02, the first limiting step 225c can guide the second end 212 into the first groove 225a, reducing the risk of the second end 212 entering the second groove 225b, thereby improving the accuracy of the movement direction of the second end 212 during the locking process of the adapter 01 and the optical fiber connector 02, which is beneficial to reduce the difficulty of locking the adapter 01 and the optical fiber connector 02.

[0140] During the unlocking process of the adapter 01 and the optical fiber connector 02, the driving slider 22 moves along the first direction X into the accommodating cavity 11, so that the second end 212 is released from the abutment with the limiting portion 223. At this time, the pull rod 21 can swing around the first end 211. At the same time, the third limiting step 225e can abut against the second end 212 to reduce the risk of the second end 212 reversely entering the first groove body 225a, resulting in the failure to unlock the adapter 01 and the optical fiber connector 02, so that the second end 212 can smoothly enter the second groove body 225b, thereby improving the accuracy of the movement direction of the second end 212 during the unlocking process of the adapter 01 and the optical fiber connector 02, which is beneficial to reduce the difficulty of unlocking the adapter 01 and the optical fiber connector 02.

[0141] like Fig.12 As shown, the slide groove 225 is provided with a fourth limiting step 225f. Along the first direction X, the fourth limiting step 225f is arranged opposite to the first guide surface 227a. The second end 212 can abut against the fourth limiting step 225f to limit the second end 212 from moving along the first guide surface 227a in a direction away from the second limiting surface 228.

[0142] In this embodiment, a fourth limiting step 225f is provided to reduce the risk of the second end 212 moving in the opposite direction along the first guide surface 227a, that is, to reduce the risk of the second end 212 moving along the first guide surface 227a in a direction away from the second limiting surface 228, thereby reducing the risk that the second end 212 cannot enter the second groove body 225b, resulting in the pull rod 21 and the slider 22 cannot be unlocked, thereby improving the accuracy of the movement direction of the second end 212, and further reducing the difficulty of unlocking the pull rod 21 and the slider 22.

[0143] In any of the above embodiments, during the process of locking or unlocking the adapter 01 and the optical fiber connector 02, it is necessary to first push the slider 22 to move inside the accommodating cavity 11 along the first direction X. After the second end 212 abuts against the first limiting surface 226 or the second limiting surface 228, it is necessary to drive the slider 22 to move outside the accommodating cavity 11 along the first direction X, so that the second end 212 abuts against the limiting portion 223 or the second end 212 enters the second groove 225b. The movement of the slider 22 outside the accommodating cavity 11 along the first direction X can be manually controlled by the operator to simplify the structure of the adapter 01, or can be automatically controlled by the first elastic member 23 to simplify the operation of the operator.

[0144] Based on the adapter 01 in any of the above embodiments, the structure of the optical fiber connector 02 is as follows: Fig.13 and Fig.14 As shown, the optical fiber connector 02 includes an outer shell 3 and a core connection component 4 installed on the outer shell 3, the core connection component 4 includes at least two core plugs 42, a second elastic member 43, an inner shell 41 and a tail sleeve 44, the outer shell 3 is sleeved on the outside of the inner shell 41, that is, at least a part of the inner shell 41 is located inside the outer shell 3, a part of the core plug 42 is located in the outer shell 3, and along the first direction X, one end of the core plug 42 extends to the outside of the outer shell 3 and is exposed, one end of the second elastic member 43 abuts against the inner shell 41, and the other side abuts against the core plug 42, and the tail sleeve 44 is arranged on the side of the inner shell 41 away from the core plug 42 and is exposed.

[0145] When the two optical fiber connectors 02 are inserted into the adapter 01 in opposite directions along the first direction X, a portion of the ferrule 42 of the optical fiber connector 02 will be inserted into the first docking channel 15 and the second docking channel 16, and the two ferrules 42 opposite to each other along the first direction X will abut against each other to achieve docking of the two optical fiber connectors 02. A second elastic member 43 is provided between the ferrule 42 and the inner shell 41, which is beneficial to achieving the stability of docking of the two ferrules 42 opposite to each other along the first direction X, reducing the risk of failure of the optical fiber connector 02 due to separation of the ferrule 42, thereby helping to improve the working stability of the optical fiber connector assembly, communication equipment and communication system.

[0146] like Fig.13As shown, the housing 3 is provided with a slot 31, which is the above-mentioned mating portion for engaging with the hook 222, that is, the slot 31 is used to engage with the hook 222 on the locking module 2 to limit the movement of the optical fiber connector 02 relative to the locking module 2.

[0147] In this embodiment, in the process of pushing the optical fiber connector 02 along the first direction X, the hook 222 can extend into the slot 31 and engage with the slot 31, or the hook 222 can leave the slot 31 and release the engagement with the slot 31, that is, the optical fiber connector 02 and the adapter 01 can be locked or unlocked by the movement of the optical fiber connector 02 in the first direction X, which simplifies the locking and unlocking operations of the optical fiber connector 02 and the adapter 01, and reduces the operating space required for the installation and removal of the optical fiber connector 02 and the adapter 01, thereby facilitating the improvement of the arrangement density of the optical fiber connector 02 in the limited space, and further facilitating the improvement of the integration of the optical fiber connector assembly, so as to improve the bandwidth of the communication equipment and the communication system. The locking or unlocking of the optical fiber connector assembly is achieved by the relative movement between the slider 22 and the pull rod 21, which is conducive to simplifying the structure of the adapter 01, thereby facilitating the reduction of the size of the adapter 01, so as to increase the number of optical fiber connector assemblies set in the limited space, so as to facilitate further improving the bandwidth of the communication equipment and the communication system.

[0148] In one embodiment, the card slot 31 is directly disposed on the housing 3 to simplify the structure of the housing 3; in another embodiment, as Fig.13 As shown, a limiting protrusion 36 is provided on the housing 3 , and the clamping groove 31 is provided on the limiting protrusion 36 , so as to facilitate the processing of the clamping groove 31 and help reduce the overall size and weight of the housing 3 .

[0149] like Fig.13 As shown, the block body 221 is provided with a first mating surface 221d extending obliquely, and the housing 3 is provided with a second mating surface 35 extending obliquely. When the optical fiber connector 02 is inserted into the adapter 01, the second mating surface 35 can abut against the first mating surface 221d. The oblique surface cooperation between the first mating surface 221d and the second mating surface 35 reduces the risk of damage to the edge of the housing 3 or the block body 221 due to stress concentration during the insertion of the optical fiber connector 02, thereby facilitating the extension of the service life of the adapter 01 and the optical fiber connector 02.

[0150] In one embodiment, if Fig.13 As shown, the inner shell 41 is integrally formed with the outer shell 3 or fixedly and non-detachably connected to increase the structural stability of the core connection assembly 4 .

[0151] In another embodiment, if Fig.15 and Fig.16As shown, the inner shell 41 is detachably connected to the outer shell 3; the inner shell 41 is provided with a snap-fitting portion 411, and the outer shell 3 is provided with a snap-fitting portion 32. Along the axial direction of the optical fiber connector 02, the snap-fitting portion 411 can be snap-fitted with the snap-fitting portion 32 to achieve the fixation of the inner shell 41 and the outer shell 3.

[0152] In this embodiment, the inner shell 41 is detachably connected to the outer shell 3, which can facilitate the assembly and maintenance of the optical fiber connector 02, and at the same time, it is convenient to replace the outer shell 3, the inner shell 41 or the ferrule 42 and other structures, so as to reduce the maintenance cost of the optical fiber connector 02. The outer shell 3 and the inner shell 41 are fixed by the clamping part 411 and the clamping matching part 32, which simplifies the structure of the outer shell 3 and the inner shell 41, thereby facilitating the reduction of the size of the outer shell 3 and the inner shell 41, and further facilitating the reduction of the overall size of the optical fiber connector 02, so as to further improve the arrangement density of the optical fiber connector 02.

[0153] Among them, along the height direction of the optical fiber connector 02, that is, along the second direction Z, the clamping portion 411 is relatively arranged on one side or both sides of the inner shell 41. When the clamping portion 411 is arranged on one side of the inner shell 41, the structure of the inner shell 41 is simplified, thereby reducing the cost of the inner shell 41; when the clamping portion 411 is arranged on both sides of the inner shell 41, the outer shell 3 can be installed positively or reversely according to the connection requirements, so as to facilitate the replacement of the docking polarity of the optical fiber connector 02, thereby improving the application range of the optical fiber connector 02.

[0154] Specifically, Fig.16 As shown, a through groove 37 is provided on the outer shell 3. Along the first direction X, the through groove 37 passes through one side of the outer shell 3, and along the third direction Y, the cavity inside the outer shell 3 is connected with the outside through the through groove 37. In the third direction Y, the through groove 37 is provided on one side or both sides of the outer shell 3. In the process of the outer shell 3 and the inner shell 41 being clamped and fixed, the provision of the through groove 37 can facilitate the elastic deformation of the part of the outer shell 3, thereby facilitating the clamping portion 411 to be clamped into the clamping mating portion 32, thereby reducing the difficulty of installing the outer shell 3 and the inner shell 41.

[0155] In one embodiment, if Fig.15 As shown, the number of the core connection assembly 4 can be one to simplify the structure of the optical fiber connector 02 .

[0156] In another embodiment, if Fig.17 As shown, the number of core connection components 4 is at least two, and the plurality of core connection components 4 are distributed along the width direction of the optical fiber connector 02, that is, distributed along the third direction Y; the outer shell 3 includes a second shell 33 and a third shell 34, the second shell 33 is connected to the inner shell 41, and the ferrule 42 is installed in the third shell 34, as shown in FIG. Fig.17 As shown, the number of the third housing 34 is one, or, as Fig.18As shown, a plurality of third shells 34 are distributed along the width direction of the optical fiber connector 02 .

[0157] In this embodiment, if there is only one third shell 34, the structure of the outer shell 3 is simplified, and the processing difficulty and cost of the outer shell 3 are reduced; if there are multiple third shells 34, the connection stability between the third shell 34 and the ferrule 42 is increased, which is beneficial to improving the working stability of the optical fiber connector assembly, communication equipment and communication system.

[0158] In any of the above embodiments, Fig.18 As shown, the ferrule 42 may be an LC ferrule 42, or, as Fig.19 As shown, the ferrule 42 may be an MT ferrule 42 .

[0159] In this embodiment, the ferrule is an LC ferrule or an MT ferrule, which increases the types of ferrules 42 that can be selected, thereby facilitating the improvement of the application scope of the optical fiber connector 02. When the ferrule 42 is an LC ferrule, the cost of the optical fiber connector 02 is reduced, and the overall size of the optical fiber connector 02 is reduced, so as to improve the arrangement density of the optical fiber connector 02. In addition, the LC ferrule can improve durability and reduce the rewiring work caused by cross-connection. When the ferrule 42 is an MT ferrule, the density of optical fiber connection is improved, thereby facilitating the further improvement of the bandwidth of communication equipment and communication systems.

[0160] In summary, in one embodiment, the locking steps of the optical fiber connector assembly provided in the present application are as follows:

[0161] The operator drives the optical fiber connector 02 to move along the first direction X toward the adapter 01, so that the optical fiber connector 02 is inserted into the adapter 01. When the second mating surface 35 abuts against the first mating surface 221d, the hook 222 is located on one side of the optical fiber connector 02 in the third direction Y. As the optical fiber connector 02 continues to be inserted, the slider 22 moves along the first direction X under the push of the optical fiber connector 02, the first elastic member 23 is stretched or compressed and generates a rebound force, and the second end 212 of the pull rod 21 moves along the slide groove 225, and the second end 212 is guided into the first groove body 225a by the second limiting step 225d and moves along the first groove body 225. a moves until the second end 212 abuts against the first limiting surface 226 in the first direction X. When the slider 22 moves along the first direction X toward the inside of the adapter 01, the guide column 222a moves along the first guide groove 12. When the cantilever 221b abuts against the boss 18 in the third direction Y, the cantilever 221b elastically deforms toward the direction approaching the optical fiber connector 02 under the action of the boss 18, so that the hook 222 moves toward the direction approaching the optical fiber connector 02 in the third direction Y and extends into the slot 31. The hook 222 is fixedly engaged with the slot 31 in the first direction X, thereby realizing the locking of the slider 22 and the optical fiber connector 02.

[0162] After the second end 212 abuts against the first limiting surface 226 in the first direction X, the operator cancels the control of the optical fiber connector 02, and the slider 22 moves toward the outside of the adapter 01 along the first direction X driven by the rebound force of the first elastic member 23, so that the second end 212 abuts against the limiting portion 223 in the first direction X, thereby realizing the locking of the pull rod 21 and the slider 22, and further completing the locking operation of the adapter 01 and the optical fiber connector 02.

[0163] In one embodiment, the unlocking steps of the optical fiber connector assembly provided in the present application are as follows:

[0164] The operator pushes the optical fiber connector 02 along the first direction X toward the inside of the adapter 01. The slider 22 moves along the first direction X under the push of the optical fiber connector 02, so that the second end 212 is released from the abutment with the limiting portion 223, and the second end 212 is abutted with the first guide surface 227a. As the operator continues to push the optical fiber connector 02, the second end 212 moves along the first guide surface 227a until the second end 212 abuts with the second limiting surface 228. Thereafter, the operator cancels the control of the optical fiber connector 02. The slider 22 moves along the first direction X toward the outside of the adapter 01 under the drive of the rebound force of the first elastic member 23, so that the second end 212 directly enters the second groove 225b and moves along the side wall of the second groove 225b, so as to achieve the unlocking of the pull rod 21 and the slider 22.

[0165] When the slider 22 moves toward the outside of the adapter 01 along the first direction X, the guide column 222a moves along the first guide groove 12. When the cantilever 221b separates from the boss 18, the cantilever 221b elastically deforms in the direction away from the optical fiber connector 02 under the action of its own rebound force, so that the hook 222 moves in the third direction Y in the direction away from the optical fiber connector 02 and leaves the slot 31. The hook 222 and the slot 31 are released from the engagement in the first direction X, thereby realizing the unlocking of the slider 22 and the optical fiber connector 02, and then completing the unlocking operation of the adapter 01 and the optical fiber connector 02.

[0166] It can be seen that in this embodiment, the optical fiber connector 02 and the adapter 01 can be locked or unlocked by only pushing the optical fiber connector 02 along the first direction X, which simplifies the locking and unlocking operations of the optical fiber connector 02 and the adapter 01, and reduces the operating space required for the installation and removal of the optical fiber connector 02 and the adapter 01, thereby facilitating the improvement of the arrangement density of the optical fiber connector 02 in the limited space, and further facilitating the improvement of the integration of the optical fiber connector assembly, so as to improve the bandwidth of the communication equipment and the communication system. The locking or unlocking of the optical fiber connector assembly is achieved through the relative movement between the slider 22 and the pull rod 21, which is conducive to simplifying the structure of the adapter 01, thereby facilitating the reduction of the size of the adapter 01, so as to facilitate the increase of the number of optical fiber connector assemblies set in the limited space, thereby facilitating the further improvement of the bandwidth of the communication equipment and the communication system.
