Description

Technical Field

[0001] This application relates to the technical field of fiber optic connectors, and particularly to a connector assembly. Background Art

[0002] With the large-scale deployment of FTTH (Fiber To The Home), pre-connected products that reduce construction costs, lower construction technical requirements, and simplify construction difficulties are increasingly widely used.

[0003] However, there are often a lot of dust in the existing construction environment. If the end face is contaminated with dust, it will lead to a decline in optical performance; while cleaning the end face requires additional labor and material costs.

[0004] Currently, the dust cap plays an important role in the optical fiber system. It can protect the optical fiber connector, optical fiber adapter, optical interface of the optical module, and ports of other devices from external environmental pollution and external force damage, preventing serious network slowdown or network failure.

[0005] In related technologies, fiber optic connectors and adapters generally use pluggable plastic dust caps at the ports for protection and dust prevention. However, the manually pluggable plastic dust caps have the following disadvantages: First, they are easily lost; second, they are easily overlooked and not installed in time when the connector is pulled out. Moreover, the dust cap is manually assembled and disassembled, so there is a possibility of missed assembly and improper assembly at the construction site; third, even if a dust cap is provided, when installing, since the dust cap needs to be removed, the port is in an unprotected state during the docking process, and it is also easy for the end face to be contaminated with dust.

[0076] The connector assembly provided in the embodiments of this application includes two fiber optic connectors. A dust cover is provided inside the fiber optic connector. When the fiber optic connectors are not docked, the sliding sleeve is in the first position, and at this time the dust cover is in the closed state, which can play a dust-proof role. When the fiber optic connectors are docked, under the push of the connector docked with it, the sliding sleeve will move from the first position to the second position. At this time, the sliding sleeve will drive the dust cover to rotate, so as to be in the open state, exposing the optical fiber for docking. In this application, since the dust cover is installed on the ferrule carrier and the movement of the sliding sleeve is used to drive the opening or closing of the dust cover, this application does not need to disassemble and assemble the dust cover to meet the dust-proof requirements, and there is no need to worry about loss, missing assembly or improper assembly. Since the dust cover is gradually opened during the docking process, even if the dust cover is opened, at this time, since the docked connector has been inserted, it can also play a dust-proof role. Therefore, the port is always in a protected state during the docking process, and it is not easy for the butt end face to be contaminated with dust. Description of the Drawings

[0098] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0099] See Figure 1 , Figure 2 As shown in Figure 2 and Figure 2At the right end of the middle), it is used to connect the tail sheath, optical cable, etc.; the ferrule mounting carrier 11 is installed inside the housing 10, and the ferrule mounting carrier 11 is used to install the ferrule assembly 15. The dust cap 12 is also located inside the housing 10 and is close to the plug end of the housing 10. The dust cap 12 is movably installed on the ferrule mounting carrier 11 so that it can rotate to achieve closing or opening; the sliding sleeve 13 is arranged inside the housing 10, and the sliding sleeve 13 can move axially along the housing 10 inside the housing 10. From the plug end to the tail end, the sliding sleeve 13 has a first position and a second position arranged in sequence relative to the housing 10 inside the housing 10; when the sliding sleeve 13 is in the first position, the dust cap 12 is closed to cover the end of the ferrule mounting carrier 11 (as Figure 1 shown), so as to prevent dust and the like from entering the housing 10, avoid contaminating the port, and prevent the optical performance from deteriorating due to port contamination. When the sliding sleeve 13 moves to the second position, the sliding sleeve 13 drives the dust cap 12 to rotate and open from the end of the ferrule mounting carrier 11, so that the optical fiber 1 can be docked.

[0100] In the optical fiber connector provided by the embodiment of the present application, a dust cap 12 is provided inside it. When the optical fiber connector is not docked, the sliding sleeve 13 is in the first position. At this time, the dust cap 12 is in a closed state, which can play a dust-proof role. When the optical fiber connector is docked, under the push of the connector docked with it, the sliding sleeve 13 will move from the first position to the second position. At this time, the sliding sleeve 13 will drive the dust cap 12 to rotate, so as to be in an open state, exposing the optical fiber 1 for docking. In the present application, since the dust cap 12 is installed on the ferrule mounting carrier 11 and the movement of the sliding sleeve 13 is used to drive the dust cap 12 to open or close, the present application does not need to disassemble and assemble the dust cap 12 to meet the dust-proof requirements, and there is no need to worry about loss, missing assembly or improper assembly. Since the dust cap 12 is gradually opened during the docking process, even if the dust cap 12 is opened, at this time, since the docked connector has been plugged in, the same dust-proof effect can be achieved. Therefore, the port is always in a protected state during the docking process, and it is not easy for the butt end face to be contaminated with dust.

[0101] The optical fiber connector with a dust cap provided by the present application is applicable to places with a lot of dust such as compartments, meets the needs of compartments, etc., and has flexible wiring.

[0102] It can be understood that the optical fiber connector provided by the embodiment of the present application can be used as an MPO female head connector. For example, as an example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8Schematic diagrams of the components of an MPO female connector, which can also be used as an MPO male connector. For example, Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 are schematic diagrams of the components of an MPO male connector.

[0103] To rotate the dust cover 12 to open or close it, for example, see Figure 3 、 Figure 4 and Figure 5 As shown, a first arc groove 111 is provided on the outer wall of the ferrule carrier 11; a second bump 120 is provided on the inner wall of the dust cover 12, and the second bump 120 slides in the first arc groove 111.

[0104] Driven by the sliding sleeve 13, the dust cover 12 can be flipped under the cooperation of the second bump 120 and the first arc groove 111, so as to realize the opening or closing of the dust cover 12.

[0105] To drive the dust cover 12 to flip it, for example, see Figure 5 、 Figure 6 and Figure 7 As shown, a third bump 121 and a second straight groove 122 are further provided on the dust cover 12; a first bump 130 and a first straight groove 131 are sequentially provided on the side wall of the sliding sleeve 13 from top to bottom. The first straight groove 131 extends along the axis of the housing 10. When the dust cover 12 is closed, the second straight groove 122 is perpendicular to the first straight groove 131; the first bump 130 slides in the second straight groove 122, and the third bump 121 slides in the first straight groove 131.

[0106] When the sliding sleeve 13 moves, its first bump 130 pushes the dust cover 12 in the second straight groove 122. Under the cooperation of the third bump 121 and the first straight groove 131, the dust cover 12 has a tendency to tilt and rotate. Then, under the cooperation of the second bump 120 and the first arc groove 111, the dust cover 12 rotates relative to the ferrule carrier 11 on the ferrule carrier 11, so as to realize the opening or closing of the dust cover 12.

[0107] See Figure 4 and Figure 12As shown, in order to facilitate the installation of the dust cover 12, a third linear groove 112 is further provided on the outer wall of the ferrule carrier 11. One end of the third linear groove 112 communicates with the first arc groove 111, and the other end extends along the axis of the housing 10 to the end of the ferrule carrier 11. During installation, the second bump 120 of the dust cover 12 is slid into the third linear groove 112 from the end, and then slides into the first arc groove 111 along the third linear groove 112 to complete the assembly. During disassembly, the second bump 120 of the dust cover 12 is slid into the third linear groove 112 from the first arc groove 111, and then slides out from the end along the third linear groove 112. Of course, the end of the third linear groove 112 can be designed to be flared.

[0108] See Figure 6 and Figure 7 As shown, as an example, when used as an MPO female head connector, the first bump 130 and the first linear groove 131 are provided on the inner wall surface of the side wall of the sliding sleeve 13.

[0109] See Figure 14 and Figure 15 As shown, as another example, when used as an MPO male head connector, the first bump 130 and the first linear groove 131 are provided on the outer wall surface of the side wall of the sliding sleeve 13.

[0110] See Figure 1 、 Figure 3 and Figure 5 As shown, as an example, when used as an MPO female head connector, the dust cover 12 includes a cover body 123 with an arc surface and two side plates 124 respectively connected to both sides of the cover body 123. The second bump 120, the third bump 121 and the second linear groove 122 are located on the side plate 124; the end of the ferrule carrier 11 close to the insertion end is an arc surface or an inclined surface adapted to the cover body 123, so that the distance from the upper side of this end to the end face of the insertion end is greater than the distance from the lower side of this end to the end face of the insertion end.

[0111] From Figure 1 and Figure 3 It can be seen that the difference between the distance from the upper side of the end of the ferrule carrier 11 close to the insertion end to the end face of the insertion end and the distance from the lower side of this end to the end face of the insertion end is L1, so that the end of the ferrule carrier 11 is an arc surface or an inclined surface. The advantage is that it cooperates with the shape of the cover body 123, making the rotation of the dust cover 12 smoother and more convenient, and not easily getting stuck.

[0112] See Figure 9 、 Figure 13 and Figure 14As shown, as another example, for instance, when used as an MPO male connector, the dust cap 12 includes a cover body 123 with an arc surface and two side plates 124 respectively connected to both sides of the cover body 123. The second bump 120, the third bump 121, and the second straight groove 122 are located on the side plates 124. The end of the sliding sleeve 13 near the insertion end has an arc surface or an inclined surface adapted to the cover body 123, such that the distance from the upper side of this end to the end face of the insertion end is greater than the distance from the lower side of this end to the end face of the insertion end.

[0113] From Figure 9 and Figure 14 it can be seen that the difference in the distance from the upper side of the end of the sliding sleeve 13 near the insertion end to the end face of the insertion end and the distance from the lower side of this end to the end face of the insertion end is L2, making the end of the sliding sleeve 13 have an arc surface or an inclined surface. The advantage is that it matches the shape of the cover body 123, making the rotation of the dust cap 12 smoother and more convenient, and not easily getting stuck.

[0114] When the fiber optic connector is not in use for docking, in order to keep the dust cap 12 in a normally closed state and ensure the dust-proof and protection effects, it can be achieved by adding an elastic member.

[0115] For example, as an example, refer to Figure 1 and Figure 2 as shown, or refer to Figure 9 and Figure 10 as shown. A first step 100 is provided inside the housing 10, and a first elastic member 14 for driving the sliding sleeve 13 to move to push the dust cap 12 to rotate to the closed state is provided between the sliding sleeve 13 and the first step 100.

[0116] It can be understood that the above-mentioned first elastic member 14 can use common components such as a spring. Under the action of the spring force, the sliding sleeve 13 is pushed by the spring to the first position, so that the dust cap 12 is in a normally closed state.

[0117] To prevent the first elastic member 14 from detaching from the sliding sleeve 13, resulting in the dust cap 12 not being in a normally closed state when the fiber optic connector is not docked, refer to Figure 6 or Figure 14 as shown. A first abutting portion 132 is provided on the sliding sleeve 13, and the first elastic member 14 abuts on the first abutting portion 132.

[0118] It can be understood that the position of the above-mentioned first step 100 can be designed according to actual needs. As an example, for instance, when used as an MPO female connector, refer to Figure 1 and Figure 2As shown, the first step 100 is provided on the inner wall of the housing 10. As another example, for instance, when used as an MPO male connector, refer to Figure 9 and Figure 10 As shown, the first step 100 is provided on the inner wall of the tail handle 17.

[0119] When the optical fiber connector is plugged into the docking optical fiber connector, in order to prevent the two from detaching, a clamping portion can be provided for clamping to fix the optical fiber connector and the docking optical fiber connector. For example, as an example, a first clamping portion 110 for clamping with the docking optical fiber connector is provided on the ferrule carrier 11.

[0120] Furthermore, refer to Figure 1 and Figure 3 As shown, when the optical fiber connector is an MPO female connector, the first clamping portion 110 is an elastic buckle; correspondingly, the docking optical fiber connector is an MPO male connector, which has a slot adapted to the elastic buckle. For the convenience of unlocking, refer to Figure 3 and Figure 4 As shown, a first unlocking portion 113 for driving the elastic buckle to unlock from the slot under the action of a pushing force is provided on the elastic buckle.

[0121] Furthermore, refer to Figure 9 and Figure 11 As shown, when the optical fiber connector is an MPO male connector, the first clamping portion 110 is a slot; correspondingly, the docking optical fiber connector is an MPO female connector, which has an elastic buckle adapted to the slot.

[0122] In order to fix the ferrule carrier 11, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as an example, for instance, when used as an MPO female connector, from the plugging end to the tail end, a second clamping portion 101 and a second step 102 are sequentially provided on the inner wall of the housing 10; a third clamping portion 114 is provided on the ferrule carrier 11, one end of the ferrule carrier 11 abuts against the second step 102, and the third clamping portion 114 is clamped to the second clamping portion 101.

[0123] In order to fix the ferrule carrier 11, refer to Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, for example, when used as an MPO male connector, the fiber optic connector further includes a tail guard mounting assembly. The tail guard mounting assembly includes a tail handle 17 and a lock ring 18. One end of the tail handle 17 is detachably mounted within the housing 10. The lock ring 18 is screwed onto the outer wall of the tail handle 17. A plug-in slot 103 is formed between the inner wall of the lock ring 18 and the outside of the tail handle 17. The tail guard assembly 16 is installed through the plug-in slot 103. The lock ring 18 can not only fix the tail guard assembly 16, but also play a role in limiting the housing 10. For example, it directly abuts against the end of the housing 10 to prevent the housing 10 from loosening due to axial movement after docking, or has a certain distance from the housing 10 in the axial direction of the housing 10 to limit the distance that the housing 10 can move. From the plug-in end to the tail end, a second clamping portion 101 and a second step 102 are sequentially arranged on the inner wall of the tail handle 17; a third clamping portion 114 is arranged on the ferrule carrier 11; one end of the ferrule carrier 11 abuts against the second step 102, and the third clamping portion 114 is clamped to the second clamping portion 101.

[0124] It can be understood that among the second clamping portion 101 and the third clamping portion 114, one is a clamping groove and the other is an elastic clamping buckle adapted to the clamping groove.

[0125] Further, referring to Figure 10 and Figure 11 As shown, the second clamping portion 101 is a clamping groove, and the third clamping portion 114 is an elastic clamping buckle.

[0126] To achieve screwing, referring to Figure 17 and Figure 18 As shown, a spiral groove 170 is arranged on the outer wall of the tail handle 17, and a locking hole 171 is formed at the end of the spiral groove 170; a lock ring protrusion 180 is arranged on the inner wall of the lock ring 18. The lock ring protrusion 180 slides in the spiral groove 170. When the lock ring protrusion 180 slides from the spiral groove 170 into the locking hole 171, the lock ring protrusion 180 is stuck in the locking hole 171, and the lock ring 18 can be fixed on the tail handle 17, thereby preventing the lock ring 18 from loosening and detaching from the tail handle 17 due to reasons such as vibration during use.

[0127] To prevent the tail handle 17 and the ferrule carrier 11 from being installed in the wrong direction, referring to Figure 9 、 Figure 11 and Figure 16 As shown, a first anti-fooling portion 172 is formed on the inner wall of the tail handle 17, and a second anti-fooling portion 116 adapted to the first anti-fooling portion 172 is formed on the ferrule carrier 11.

[0128] Among them, the first anti-fooling part 172 can be an anti-fooling groove provided on the tail handle 17, and the second anti-fooling part 116 can be an anti-fooling protrusion provided on the ferrule carrier 11; the first anti-fooling part 172 can be an anti-fooling protrusion provided on the tail handle 17, and the second anti-fooling part 116 can be an anti-fooling groove provided on the ferrule carrier 11.

[0129] To fix the tail handle 17 on the housing 10, referring to Figure 9 、 Figure 10 and Figure 17 as shown, a fourth engaging part 173 is provided on the tail handle 17, a fifth engaging part 104 is provided at the tail end of the housing 10, and the fourth engaging part 173 is engaged with the fifth engaging part 104.

[0130] It can be understood that among the fourth engaging part 173 and the fifth engaging part 104, one is a slot, and the other is an elastic buckle adapted to the slot. For example, referring to Figure 10 as shown, the fourth engaging part 173 is an elastic buckle, and the fifth engaging part 104 is a slot.

[0131] Referring to Figure 9 as shown, as an example, when used as an MPO male connector, the fiber optic connector further includes a tail protection assembly 16 inserted into the insertion slot 103, and the tail protection assembly 16 is used to fix the optical cable.

[0132] Among them, the tail protection assembly 16 includes a tail sheath 160, an aluminum cup 161, and an aluminum cup connecting piece 162 arranged in sequence from outside to inside along the radial direction of the housing 10; one end of the tail sheath 160 is inserted into the insertion slot 103, one end of the aluminum cup connecting piece 162 is screwed to the tail handle 17, and the aluminum cup 161 is located between the tail sheath 160 and the aluminum cup connecting piece 162.

[0133] By screwing the lock ring 18, the tail sheath 160 can be crimped between the lock ring 18, the tail handle 17, and the aluminum cup 161, and the optical cable is fixed inside the tail sheath 160 and the aluminum cup 161.

[0134] Referring to Figure 9 as shown, as an example, when used as an MPO male connector, an insert core assembly 15 is further installed in the ferrule carrier 11.

[0135] Specifically, referring to Figure 8 and Figure 9As shown, a limiting portion 115 is provided inside the ferrule carrier 11; from the plug end to the tail end, the ferrule assembly 15 includes a plug 150, a pin 151, and a second elastic member 152 arranged in sequence; a third step 153 is formed on the outer wall of the plug 150, the plug 150 passes through the limiting portion 115, and the third step 153 abuts against the end of the limiting portion 115 away from the tail end. By providing the limiting portion 115, the exposed amount of the plug 150 towards the plug end can be restricted; one end of the second elastic member 152 abuts against the pin 151. By providing the second elastic member 152, the docking force during the docking of the connector can be ensured.

[0136] It can be understood that the above-mentioned second elastic member 152 can adopt common parts such as springs. The above-mentioned limiting portion 115 can be formed by the inner wall of the ferrule carrier 11.

[0137] For the convenience of installing the second elastic member 152, referring to Figure 9 、 Figure 10 and Figure 16 As shown, as an example, a second step 102 is provided on the inner wall of the tail handle 17, and the other end of the second elastic member 152 abuts against the second step 102.

[0138] Since the housing 10 is relatively long, in order to ensure a relatively long service life of the second elastic member 152 and at the same time protect the optical fiber 1 to prevent the second elastic member 152 from damaging the optical fiber 1, referring to Figure 9 As shown, the ferrule assembly 15 further includes a top block 154, and the second elastic member 152 abuts against the second step 102 through the top block 154.

[0139] It can be understood that the top block 154, the plug 150, and the pin 151 all have fiber passing channels for the optical fiber 1 to pass through. The presence of the top block 154 can not only protect the optical fiber 1, but also make the length of the second elastic member 152 shorter, and it will not bend or knot during the assembly process, thus ensuring its relatively long service life.

[0140] Referring to Figure 1 As shown, as an example, when used as an MPO female head connector, the tail end of the housing 10 is detachably connected with a tail protection assembly 16, and the tail protection assembly 16 is used to fix the optical cable.

[0141] Specifically, referring to Figure 1 、 Figure 2As shown, a socket groove 103 is provided at the tail end of the housing 10; the tail protection assembly 16 includes a tail sheath 160, an aluminum cup 161, and an aluminum cup connector 162 that are sequentially arranged from outside to inside along the radial direction of the housing 10; one end of the tail sheath 160 is inserted into the socket groove 103, one end of the aluminum cup connector 162 is screwed to the housing 10, and the aluminum cup 161 is located between the tail sheath 160 and the aluminum cup connector 162.

[0142] See Figure 1 As shown, as an example, when used as an MPO female head connector, a ferrule carrier 11 is further installed with a ferrule assembly 15.

[0143] Specifically, see Figure 1 、 Figure 3 、 Figure 8 As shown, a limiting portion 115 is provided in the ferrule carrier 11; from the insertion end to the tail end, the ferrule assembly 15 includes a plug 150, a pin 151, and a second elastic member 152 that are sequentially arranged; a third step 153 is formed on the outer wall of the plug 150, the plug 150 passes through the limiting portion 115, and the third step 153 abuts against the end of the limiting portion 115 away from the tail end. By providing the limiting portion 115, the exposure amount of the plug 150 toward the insertion end can be restricted; one end of the second elastic member 152 abuts against the pin 151. By providing the second elastic member 152, the docking force during the docking of the connector can be ensured.

[0144] It can be understood that the above-mentioned second elastic member 152 can adopt common parts such as a spring. The above-mentioned limiting portion 115 can be formed by the inner wall of the ferrule carrier 11.

[0145] To facilitate the installation of the second elastic member 152, see Figure 2 As shown, as an example, a second step 102 is provided on the inner wall of the housing 10; the other end of the second elastic member 152 abuts against the second step 102.

[0146] Since the housing 10 is relatively long, to ensure a long service life of the second elastic member 152 and at the same time protect the optical fiber 1 to prevent the second elastic member 152 from damaging the optical fiber 1, see Figure 2 As shown, the ferrule assembly 15 further includes a top block 154, and the second elastic member 152 abuts against the second step 102 through the top block 154.

[0147] It can be understood that since the optical fiber connector provided by the embodiment of the present application can be used as an MPO female head connector or an MPO male head connector.

[0148] Based on this, the present application further provides a connector assembly, which includes two fiber optic connectors. One of the fiber optic connectors is an MPO male connector, and the other fiber optic connector is an MPO female connector. Both fiber optic connectors include a housing 10, a ferrule carrier 11, a dust cap 12, and a sliding sleeve 13. One end of the housing 10 is a plugging end, and the other end is a tail end; the ferrule carrier 11 is installed inside the housing 10; the dust cap 12 is movably installed on the ferrule carrier 11; the sliding sleeve 13 is movably arranged inside the housing 10. From the plugging end to the tail end, the sliding sleeve 13 has a first position and a second position arranged in sequence; when the sliding sleeve 13 is in the first position, the dust cap 12 closes to cover the end of the ferrule carrier 11. When the sliding sleeve 13 moves to the second position, the sliding sleeve 13 drives the dust cap 12 to rotate and open from the end of the ferrule carrier 11.

[0149] Among them, as shown in Figure 19 When the MPO male connector is inserted into the MPO female connector for docking, the housing 10 of the MPO male connector drives the sliding sleeve 13 of the MPO female connector to move to the second position, and drives the dust cap 12 of the MPO female connector to rotate to open the dust cap 12. At the same time, the ferrule carrier 11 of the MPO female connector drives the sliding sleeve 13 of the MPO male connector to move to the second position, and drives the dust cap 12 of the MPO male connector to rotate to open the dust cap 12. Finally, the optical fiber 1 in the MPO female connector is docked with the optical fiber 1 in the MPO male connector.

[0150] In this way, when the two fiber optic connectors are plugged, they simultaneously open the dust caps 12 of each other, thereby realizing the docking of the optical fibers 1 in the two fiber optic connectors.

[0151] It can be understood that since the MPO male connector needs to be inserted into the MPO female connector, the outer contour dimension of the housing 10 of the MPO male connector is smaller than the inner contour dimension of the housing 10 of the MPO female connector. As for the housing 10 of the MPO male connector driving the sliding sleeve 13 of the MPO female connector to move, and the ferrule carrier 11 of the MPO female connector driving the sliding sleeve 13 of the MPO male connector to move, designers can achieve this by designing the dimensions of relevant parts.

[0152] In order to be able to unlock after docking, as shown in Figure 9 and Figure 11 The MPO male connector is a fiber optic connector with a first latching portion 110 provided on the ferrule carrier 11, and the first latching portion 110 is a card slot. As shown in Figure 10 A second unlocking portion 105 is provided on the inner wall of the housing 10 near the plugging end; as shown inFigure 1 and Figure 3 As shown, the MPO female connector is an optical fiber connector in which a first clamping portion 110 is provided on a ferrule carrier 11, and the first clamping portion 110 is an elastic buckle, see Figure 4 As shown, the elastic buckle is provided with a first unlocking portion 113 for driving the elastic buckle to unlock from the slot under the action of a top thrust.

[0153] The second unlocking portion 105 is configured to: push the first unlocking portion 113 of the mating optical fiber connector (such as an MPO female connector) that is plugged into the optical fiber connector (such as an MPO male connector), thereby driving the elastic clip connected to the first unlocking portion 113 to unlock from the card slot.

[0154] See also Figure 19 As shown, the dotted line is the docking point of the two ferrule assemblies 15, the left side of the dotted line is the MPO female connector, and the right side is the MPO male connector. The MPO male connector is inserted into the shell 10 of the MPO female connector from the right to the left, and the shell 10 of the MPO male connector squeezes the sliding sleeve 13 of the MPO female connector to move to the left, and the dust cover 12 of the MPO female connector opens and slides to the left with the sliding sleeve 13 of the MPO female connector. At this time, the ferrule carrier 11 of the sliding sleeve 13 of the MPO female connector squeezes the sliding sleeve 13 of the MPO male connector to slide to the right, and the dust cover 12 of the MPO male connector opens and slides to the right with the sliding sleeve 13 of the MPO male connector. The first clamping portion 110 (elastic clamp at this time) on the ferrule carrier 11 of the MPO female connector is clamped into the first clamping portion 110 (card slot at this time) on the ferrule carrier 11 of the MPO male connector to achieve locking, and optical docking is now achieved.

[0155] Since the first unlocking portion 113 is located on the moving path of the second unlocking portion 105, when unlocking, the housing 10 of the MPO male connector is pinched, and the housing 10 moves backward. When the second unlocking portion 105 thereon passes the first unlocking portion 113, it pushes the first unlocking portion 113 outward, causing the elastic clip connected to the first unlocking portion 113 to disengage from the slot. At this time, the two optical fiber connectors can be unlocked and pulled out.

[0156] It is understandable that if the housing 10 of the MPO male connector is moved to abut against the locking ring 18 and is still not unlocked, the locking ring 18 can be loosened to move the locking ring 18 backward and unlocked from the tail handle 17, thereby providing sufficient travel for the second unlocking portion 105 to unlock the two optical fiber connectors.

[0157] It can be seen that the present application adopts the MPO structure, which can meet the parallel docking of multiple optical fibers; when two optical fiber connectors are inserted and docked, simple visual alignment can be achieved, and there are good anti-misoperation measures, which is convenient for operation; in addition, the connection between the two optical fiber connectors is a plug-and-play connection, which is convenient for operation, and there is a locking ring to ensure the connection stability.

[0158] The above are only specific embodiments of the present application, which enable those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features claimed herein.
