[0040] The present application provides an optical fiber connection assembly 1 .

[0041] In combination with Figures 1 to 5, in one embodiment of the present application, the optical fiber connection assembly 1 includes an installation box 10 and an optical fiber connector 20; the installation box 10 includes a box body 12 and a plug-in module 11, the box body 12 is formed with an installation cavity 121, the plug-in module 11 is arranged in the installation cavity 121, the plug-in module 11 is provided with at least two plug-in holes 111a connected to the installation cavity 121, and a connection line is provided in the installation cavity 121; the optical fiber connector 20 includes a connecting tube 21 and an optical fiber 22, the connecting tube 21 is sleeved on one end of the optical fiber 22 and inserted into the plug-in hole 111a, the connecting tube 21 is snap-fitted with the hole wall of the plug-in hole 111a, and the optical fiber 22 is connected to the connection line; the connecting tube 21 is pulled in a direction away from the plug-in hole 111a to unlock the fit between the connecting tube 21 and the plug-in module 11, so as to separate the optical fiber 22 connector 20 and the installation box 10.

[0042] In this embodiment, one end of the box body 12 is provided with an opening that communicates with the installation cavity 121. The plug-in module 11 blocks the opening and is disposed within the installation cavity 121. The plug-in module 11 may be provided with multiple insertion holes 111a that communicate with the installation cavity 121. The multiple insertion holes 111a are spaced apart in sequence. By providing multiple insertion holes 111a, the number of optical fiber connectors 20 that can be connected to the installation box 10 is increased. When installing the optical fiber 22, one end of the optical cable is first stripped to expose the optical fiber 22 and pass it through the connecting tube 21. The connecting tube 21 is then inserted into the insertion hole 111a. A connecting circuit is provided within the installation box 10. At this time, the optical fiber 22 in the connecting tube 21 is connected to the connecting circuit to achieve optical signal transmission between the optical fiber 22 and the connecting circuit. The wall of the insertion hole 111a is provided with a snap-fitting position to allow the connecting tube 21 to snap-fit ​​with the wall of the insertion hole 111a, thereby fixing the connecting tube 21 within the insertion hole 111a. At the same time, the engaging portion provided on the wall of the plug hole 111a is relatively movable with the outer wall of the connecting tube 21, so that when the connecting tube 21 is pulled away from the plug hole 111a, the engaging portion moves relative to the connecting tube 21 to release the engagement between the connecting tube 21 and the plug-in module 11. Then, by continuing to pull the connecting tube 21, the optical fiber connector 20 can be separated from the installation box 10, and the optical fiber 22 can be removed. During the installation, maintenance and removal process of the optical fiber connection assembly 1 proposed in this application, there is no need to open the installation box or fuse the optical fiber 22. The plug-in installation and removal method is relatively simple and less difficult to operate, thereby improving the efficiency of installation and maintenance.

[0043] As shown in FIG3 to FIG9 , in one embodiment of the present application, the connecting pipe 21 includes a tail sleeve 213 and a reset wedge 212 connected in sequence, and the plug-in module 11 includes a module body 111 and a retaining member 112 ;

[0044] The reset wedge 212 is inserted into the plug hole 111a, and the outer periphery of the reset wedge 212 is concavely provided with a first clamping groove 212a. The module body 111 is provided with a plug hole 111a, and the hole wall of the plug hole 111a is provided with a limiting groove 111b. The stopper 112 is movably provided in the limiting groove 111b. A first elastic member 113 is provided between the stopper 112 and the bottom of the limiting groove 111b. The stopper 112 is provided with a first convex portion on the side away from the limiting groove 111b. The clamping block 112a and the first elastic member 113 squeeze the retaining member 112, so that one end of the first clamping block 112a extends into the plug-in hole 111a and abuts against the first clamping groove 212a. The tail sleeve 213 is pulled, and the groove wall of the first clamping groove 212a presses the first clamping block 112a, so that the retaining member 112 compresses the first elastic member 113 and moves in a direction away from the first clamping groove 212a, thereby unlocking the cooperation between the connecting pipe 21 and the plug-in module 11.

[0045] In this embodiment, a protrusion is provided on one end of the reset wedge 212, and a connection hole is provided on one end of the tail sleeve 213. The protrusion passes through the connection hole to connect the tail sleeve 213 and the reset wedge 212. A limiting groove 111b is provided on the wall of the plug hole 111a for accommodating the retaining member 112, with the notch of the limiting groove 111b facing the plug hole 111a. The first elastic member 113 can be a spring, which compresses the retaining member 112 to force the first engaging block 112a against the bottom of the first engaging groove 212a, thereby achieving a snap fit between the connecting tube 21 and the plug-in module 11. Furthermore, after the connecting tube 21 is snap-fitted to the plug-in module 11, the spring can remain compressed to enhance the snap fit between the first engaging block 112a and the second engaging groove 212b. When the tail sleeve 213 is pulled away from the insertion hole 111a, the groove wall of the first engaging groove 212a squeezes the first engaging block 112a, causing the first engaging block 112a to be lifted and compressing the first elastic member 113, thereby unlocking the engagement between the connecting tube 21 and the plug-in module 11. The provision of the first elastic member 113 eliminates the need to press the switch button during the insertion and removal of the optical fiber connector 20 to connect and remove the optical fiber 22, simplifying the operation and improving work efficiency.

[0046] As shown in FIG2-3 , in one embodiment of the present application, the surface of the first engaging groove 212a away from the groove wall of the tail sleeve 213 is an inclined surface, and the side surface of the first engaging block 112a away from the tail sleeve 213 is an inclined surface and is adapted to the groove wall of the first engaging groove 212a away from the tail sleeve 213;

[0047] And / or, first engaging grooves 212a are provided on opposite sides of the reset wedge block 212, two first engaging blocks 112a are provided on both sides of each insertion hole 111a, and a first engaging block 112a is engaged with a first engaging groove 212a.

[0048] In this embodiment, when the optical connector is inserted into the insertion hole 111a, the first engaging block 112a abuts against the bottom of the first engaging groove 212a. When the tail sleeve 213 is pulled away from the insertion hole 111a, the first engaging block 112a slides along the bottom of the first engaging groove 212a until it abuts against the wall of the first engaging groove 212a. The surface of the first engaging groove 212a away from the wall of the tail sleeve 213 is designed to be inclined, and the surface of the first engaging block 112a in contact with the wall of the first engaging groove 212a is also designed to be inclined. This allows the first engaging block 112a to slide along the inclined surface of the first engaging groove 212a, allowing the wall of the first engaging groove 212a to lift the first engaging block 112a, thereby separating the first engaging block 112a from the first engaging groove 212a, thereby unlocking the connecting tube 21 from the plug-in module 11 and allowing the optical fiber connector 20 to be installed and removed. In other embodiments, the two surfaces matching the first clamping block 112a and the first clamping groove 212a may also be designed as curved surfaces. As long as the groove wall of the first clamping groove 212a can lift the first clamping block 112a, it falls within the protection scope of this application.

[0049] With or without limiting the shapes of the first snap-in block 112a and the first snap-in groove 212a, by setting two first snap-in grooves 212a on the reset wedge block 212, two first snap-in blocks 112a are set on both sides of the first plug-in hole 111a, and each first snap-in block 112a is snap-fitted with a first snap-in groove 212a, thereby improving the snap-in strength between the connecting tube 21 and the plug-in module 11 to ensure the stability of the connection of the optical fiber 22.

[0050] In combination with Figures 2-5 and 10-11, in one embodiment of the present application, the connecting tube 21 also includes a main shell 211, which is arranged on a side of the reset wedge 212 away from the tail sleeve 213. The reset wedge 212 is sleeved on one end of the main shell 211 and is movably connected to the main shell 211. A second elastic member 214 is provided between the reset wedge 212 and the main shell 211. The tail sleeve 213 is pulled in a direction away from the plug-in hole 111a to drive the reset wedge 212 to move, unlock the cooperation between the connecting tube 21 and the plug-in module 11, and compress the second elastic member 214.

[0051] In this embodiment, the tail sleeve 213 is fixedly connected to the reset wedge 212, which is movably connected to the main housing 211. Pulling the tail sleeve 213 moves the reset wedge 212, thereby unlocking the engagement between the connecting tube 21 and the plug-in module 11. The provision of the tail sleeve 213 increases the grip area for the operator when pulling the connecting tube 21, thereby improving operational convenience. The second elastic member 214 can be a spring. By arranging the second elastic member 214 between the reset wedge block 212 and the main shell 211, when the tail sleeve 213 is pulled to unlock the connecting tube 21 and the plug-in module 11, the second elastic member 214 is in a compressed state and applies a force on the reset wedge block 212 in the opposite direction to the pulling of the tail sleeve 213, thereby preventing the connecting tube 21 from being separated from the plug-in module 11, thereby improving the connection strength between the connecting tube 21 and the plug-in module 11, avoiding external interference or accidental contact with the tail sleeve 213, and further improving the stability of the connection of the optical fiber 22.

[0052] As shown in Figures 5 to 9, in one embodiment of the present application, the outer peripheral wall of the reset wedge 212 extends toward one side of the main housing 211 to form two oppositely disposed fins 212c, and the outer peripheral wall of the main housing 211 is recessed to form two oppositely disposed fin slots 211a. The two fins 212c are respectively inserted into the two fin slots 211a. The bottom of the fin slot 211a and the side of the fin 212c facing the fin slot 211a are recessed and enclosed to form a spring slot. The second elastic member 214 is a spring, which is disposed in the spring slot and abuts against the fin 212c and the slot wall of the fin slot 211a respectively.

[0053] And / or, the plug-in module 11 also includes a fixed baffle 114, a limiting hole is opened on the hole wall of the plug-in hole 111a, the limiting hole, the fixed baffle 114 covers the end of the limiting hole away from the plug-in hole 111a, and is surrounded by the hole wall of the limiting hole to form a limiting groove 111b, and the first elastic member 113 is arranged between the fixed baffle 114 and the stop member 112.

[0054] In this embodiment, the fins 212c on either side of the reset wedge 212 are arc-shaped, and the main housing 211 has a circular cross-section, so that the fins 212c mate with the fin slots 211a formed by the recesses in the outer peripheral wall of the main housing 211. The bottom of the fin slot 211a and the recess on one side of the fin 212c are positioned opposite each other, so that the two opposing recesses enclose a spring slot. A spring is positioned within the spring slot, with both ends of the spring abutting against the fins 212c and the walls of the fin slot 211a. It will be appreciated that when the optical connector is inserted into the insertion hole 111a and the connecting tube 21 is engaged with the plug-in module 11, the ends of the second elastic member 214 press against the fins 212c and the walls of the fin slot 211a, preventing the reset wedge 212 from moving relative to the main housing 211, thereby enhancing the engagement strength between the connecting tube 21 and the plug-in module 11. When the tail sleeve 213 is pulled to move the reset wedge 212 , the second elastic member 214 is compressed, thereby generating resistance to the movement of the tail sleeve 213 , thereby reducing the possibility of the optical fiber connector 20 being pulled out of the mounting box 10 due to accidental external force.

[0055] In the case where the reset wedge 212 is provided with fins or not, the plug-in module 11 further includes a fixed baffle 114. Limiting holes are provided on both sides of the plug-in hole 111a, and the outer edges of the limiting holes extend away from the plug-in hole 111a to form a baffle. The fixed baffle 114 is disposed on the side of the baffle away from the plug-in hole 111a and encloses the baffle to form a limiting groove 111b. It is understood that a strip groove can be provided on the baffle, and a strip block is protruding from the side of the fixed baffle 114 facing the baffle. By snapping the strip block into the strip groove, the fixed baffle 114 is secured to the baffle. At the same time, a first elastic member 113 is disposed between the fixed baffle 114 and the retaining member 112, so that the retaining member 112 can be movably disposed within the limiting groove 111b. Limiting columns can be protruded on both sides of the fixed baffle 114 and the retaining member 112, and the two ends of the first elastic member 113 are respectively mounted on the limiting columns of the fixed baffle 114 and the retaining member 112, thereby improving the stability of the first elastic member 113 during the elastic compression process, thereby improving the smoothness of the connecting tube 21 and the plug-in module 11 during the plug-in and pull-out process.

[0056] As shown in combination with Figures 7 and 9, in one embodiment of the present application, the end of the reset wedge 212 away from the tail sleeve 213 abuts against the middle of the main shell 211, and the middle of the main shell 211 is recessed on the side close to the reset wedge 212 to form a second clamping groove 212b. The retaining member 112 is provided with a second clamping block 112b on the side facing the insertion hole 111a. The first elastic member 113 squeezes the retaining member 112 so that the second clamping block 112b is clamped in the second clamping groove 212b. The tail sleeve 213 is pulled, and the reset wedge 212 pushes up the first clamping block 112a to separate the second clamping block 112b from the second clamping groove 212b.

[0057] In this embodiment, the groove wall of the second engaging groove 212b may be perpendicular to the groove bottom, and the cross-section of the end of the second engaging block 112b is rectangular, so that when the second engaging block 112b is engaged in the second engaging groove 212b, the groove wall of the second engaging groove 212b limits the second engaging block 112b, thereby preventing the main housing 211 from further moving along the axial direction of the plug-in hole 111a, thereby improving the engagement strength between the connecting tube 21 and the plug-in module 11. It can be understood that the groove bottom of the first engaging groove 212a and the groove wall of the second engaging groove 212b are on the same horizontal plane, and the end surfaces of the first engaging block 112a and the second engaging block 112b are also on the same horizontal plane, so that the first engaging block 112a and the second engaging block 112b are simultaneously in contact with the first engaging groove 212a and the second engaging groove 212b. At the same time, when the tail sleeve 213 is pulled to move the reset wedge 212, the first engaging block 112a moves to the notch of the first engaging groove 212a, and the second engaging block 112b also moves to the notch of the second engaging groove 212b, thereby simultaneously unlocking the engagement between the first engaging block 112a and the first engaging groove 212a, and between the second engaging block 112b and the second engaging groove 212b, thereby unlocking the engagement between the connecting tube 21 and the plug-in module 11. Second engaging grooves 212b are provided on opposite sides of the central portion of the main housing 211, and the retaining members 112 on both sides of the plug-in hole 111a are also provided with second engaging blocks 112b, ensuring that both sides of the connecting tube 21 engage with the plug-in module 11, further improving plug-in stability.

[0058] As shown in Figures 6 to 11, in one embodiment of the present application, the cross-sectional dimension of the middle portion of the main shell 211 is larger than the cross-sectional dimension of the two ends of the main shell 211, and the connection surface 211b between the middle portion of the main shell 211 and the end of the main shell 211 away from the reset wedge block 212 is a slope. The connecting tube 21 is inserted into the plug hole 111a, and the connecting surface 211b presses and lifts the first clamping block 112a to allow the connecting tube 21 to be inserted into the plug hole 111a.

[0059] In this embodiment, the shape of the main housing 211 matches the shape of the insertion hole 111a. The cross-sectional dimensions of the middle portion of the main housing 211 are larger than those of the ends, allowing the middle portion of the main housing 211 to engage with the retaining member 112. The diameter of the insertion hole 111a at the end closest to the mounting cavity 121 is smaller, allowing the end of the main housing 211 facing the mounting cavity 121 to fit tightly with the cavity, thereby improving the connection strength between the connecting tube 21 and the plug-in module 11.

[0060] The connection between the middle portion of the main housing 211 and the end away from the reset wedge 212 is designed as an inclined surface. When the main housing 211 is inserted into the insertion hole 111a, the inclined surface of the connection will squeeze the first clamping block 112a, causing it to be lifted, thereby allowing the connecting tube 21 to be smoothly inserted into the insertion hole 111a. In other embodiments, the connection between the middle portion and the end of the main housing 211 can also be designed as a curved surface. As long as the connection can lift the first clamping block 112a when the main housing 211 is inserted into the insertion hole 111a, it falls within the scope of protection of this application.

[0061] As shown in Figures 6 to 9, in one embodiment of the present application, a sealing groove is formed at one end of the connecting tube 21 facing the plug hole 111a, and a sealing ring is provided in the sealing groove. When the connecting tube 21 is inserted into the plug hole 111a, the sealing ring is in tight contact with the wall of the plug hole 111a.

[0062] And / or, the cross-sections of two opposite sides of the tail sleeve 213 are concave-convex.

[0063] In this embodiment, a sealing ring is provided on one end of the main housing 211 facing the insertion hole 111a, thereby improving the connection strength between the connecting tube 21 and the plug-in module 11 and the sealing of the insertion hole 111a. This prevents moisture or dust from entering the installation cavity 121 through the insertion hole 111a during long-term use of the optical fiber connection assembly 1, thereby affecting the connection between the optical fiber 22 and the connecting line. A sealing ring may also be provided on the outer periphery of the plug-in module 11 to further improve the sealing and waterproof properties between the module body 111 and the box body 12.

[0064] When a sealing ring is provided at the end of the main housing 211 or not, the cross-sections of the opposite sides of the tail sleeve 213 are both concave and convex, thereby increasing the friction of the tail sleeve 213 and facilitating the operation of pulling out the tail sleeve 213.

[0065] In combination with Figures 2 and 5, in one embodiment of the present application, the optical fiber connector 20 also includes a hot melt tube 24, a ferrule 25, a ferrule stop 26 and a pressure ring 23 arranged in the connecting tube 21. The ferrule 25 and the ferrule stop 26 are connected and are sleeved on one end of the optical fiber 22 facing the plug hole 111a. The pressure ring 23 is crimped to one end of the optical fiber 22 facing the ferrule stop 26, and the hot melt tube 24 is sleeved on the outer periphery of the pressure ring 23 and the optical fiber 22.

[0066] In this embodiment, when assembling the optical fiber connector 20, the stripped end of the optical cable is first passed through the ferrule 25 and the ferrule stop 26, until it emerges at the end of the ferrule 25 away from the ferrule stop 26. The main housing 211 and the reset wedge 212 are then assembled and placed around the ferrule 25 and the ferrule stop 26. The pressure ring 23 is then placed over the stripped portion and crimped to seal it securely. The pressure ring 23 provides protection for the optical fiber 22. The hot melt tube 24 is then placed around the pressure ring 23 and the optical fiber 22, abutting against the reset wedge 212. The hot melt tube 24 further seals the optical fiber 22. Finally, the tail sleeve 213 is connected to the reset wedge 212, completing the assembly of the optical fiber connector 20.

[0067] As shown in Figure 4, in one embodiment of the present application, the installation box 10 also includes a cable management tray 14 and a plug connector 13. The cable management tray 14 is arranged in the installation cavity 121 for placing the connecting line. There are at least two plug connectors 13, and they are respectively arranged on one side of a plug hole 111a facing the installation cavity 121. The two ends of the plug connector 13 are respectively inserted with a connecting line and an optical fiber 22 for connection, so that the optical fiber 22 is connected to the connecting line.

[0068] In this embodiment, the connector 13 connects the optical fiber 22 to the connection line, improving the stability and strength of the connection. One end of the connector 13 plugs into the insertion hole 111a, and the other end is located in the installation cavity 121. Multiple connectors 13 can be provided, one for each insertion hole 111a, allowing the installation box 10 to simultaneously implement network transmission on multiple lines. The installation of a cable management tray 14 within the installation cavity 121 further tidies the connection lines and improves the convenience of wiring layout.

[0069] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
