Description

Technical Field

[0001] This application relates to the field of optical fiber connection device technologies, and in particular to a distribution box. Background Art

[0002] Distribution boxes can usually be directly installed in standard cabinets and are suitable for large-scale optical fiber networks. Distribution boxes are usually provided with fiber module cassettes with fixed configurations. Users can select corresponding fiber module cassettes according to the quantity and specifications of optical cables, which is convenient for network adjustment and expansion. Then, adapters are fixed to the fiber module cassettes to achieve the connection between optical fiber connectors and ensure that the optical fibers maintain the correct alignment angle.

[0003] The fiber module cassettes need to have the functions of cable termination and being suitable for distribution boxes. Currently, most fiber module cassettes have highly modular characteristics. However, when the fiber module cassettes are plugged into the distribution box, adjacent fiber module cassettes often collide with each other, thus scratching or even wearing the optical fiber cables. Summary of the Invention

[0004] In order to reduce the collision between adjacent fiber module cassettes and thus reduce the possibility of the fiber module cassettes damaging the optical fiber cables, this application provides a distribution box.

[0005] The distribution box provided by this application adopts the following technical solutions:

[0006] A distribution box for accommodating highly modular fiber module cassettes, comprising a distribution box body; one side of the distribution box body is provided with a front opening; the distribution box body is provided with a backplane; the backplane is arranged opposite to the front opening; a fixing block is arranged on the outer peripheral side of the distribution box body; the fixing block is installed on the backplane; a connecting groove is arranged on one side of the fixing block close to the backplane; the opening of the connecting groove penetrates through the backplane; a spring is arranged at the bottom of the connecting groove; one end of the spring is connected to the connecting groove, and the other end is provided with a first connecting member; a part of the first connecting member penetrates through the connecting groove; a second connecting member matching the first connecting member is arranged on the outer peripheral side of the fiber module cassette for plugging into the first connecting member; a limiting strip inclined towards the second connecting member is arranged at the end of the first connecting member close to the second connecting member; a first flange is arranged on one side of the limiting strip close to the second connecting member; the second connecting member is provided with a second flange for matching and clamping with the first flange; a third flange is arranged on the side of the limiting strip far from the second connecting member; and the fixing block is provided with a limiting hole matching the third flange.

[0007] By adopting the above technical solution, the main body of the distribution box is provided with a front opening, which facilitates the insertion of the optical fiber module cartridge from one side of the front opening. When the optical fiber module cartridge is inserted into the main body of the distribution box, the optical fiber module cartridge is pushed until the second connecting member abuts against the first connecting member, causing the first connecting member to move towards the bottom of the connecting groove. At the same time, the first connecting member compresses the spring, and then the first connecting member slides until the third flange partially penetrates into the limiting hole, thereby fixing the first connecting member. And during the process of the second connecting member pushing the first connecting member to slide, the notch of the connecting groove forces the limiting strip to tilt towards the second connecting member. Then, after the first connecting member is fixed, the first flange blocks the movement of the second flange, thereby fixing the second connecting member. Therefore, the first connecting member is fixed by the cooperation of the third flange and the limiting hole, and then the second connecting member is fixed to the first connecting member by the mutual cooperation of the first flange and the second flange, so that the installation of the optical fiber module cartridge is more stable, reducing the possibility of adjacent optical fiber module cartridges colliding with each other, effectively reducing the wear of the optical fiber module cartridge on the optical fiber cable, and maintaining the normal operation of the optical fiber module cartridge. When the optical fiber module cartridge needs to be detached from the main body of the distribution box, the user can press the third flange to make the third flange disengage from the limiting hole, and then drive the automatic reset of the first connecting member through the automatic reset of the spring. During the reset process of the first connecting member, the first connecting member will push the second connecting member to move, and the limiting strip will also gradually reset, so that the second flange moves away from the first flange. Therefore, the first connecting member releases the second connecting member, and at the same time, the first connecting member partially pushes the optical fiber module cartridge out of the main body of the distribution box, facilitating the user to quickly pull out the optical fiber module cartridge from the main body of the distribution box, saving time and effort and improving work efficiency.

[0008] Preferably, there are at least two of the limiting strips; there are at least two of the limiting holes; there are at least two of the second flanges; each of the limiting strips is provided with the first flange and the third flange; at least one of the limiting strips is arranged opposite to another limiting strip; the limiting holes correspond to the third flanges one by one; the first flanges correspond to the second flanges one by one.

[0009] By adopting the above technical solution, when at least one limiting strip is arranged opposite to another limiting strip, the fiber optic module cartridge is inserted into the main body of the distribution box, and the second connecting piece forces the first connecting piece to move towards the bottom of the connecting groove, then the notch of the connecting groove forces the limiting strip to incline towards the direction of the second connecting piece; when the first connecting piece slides to a position where each third flange is partially inserted into the corresponding limiting hole, each first flange will block the movement of the second flange, thereby making the connection between the first connecting piece and the fixed block more stable, and at the same time making the connection between the first connecting piece and the second connecting piece more stable, thus making the installation of the fiber optic module cartridge more stable. Therefore, the oppositely arranged limiting strips can effectively enhance the stability of the fiber optic module cartridge installed on the main body of the distribution box, thereby reducing the collision between adjacent fiber optic module cartridges, and further reducing the possibility of damage to the fiber optic cable.

[0010] Preferably, a reset member is provided on the side of the limiting hole away from the first connecting piece for pressing the third flange until the third flange disengages from the limiting hole.

[0011] By adopting the above technical solution, a reset member is provided on the side of the limiting hole away from the first connecting piece. When the fiber optic module cartridge is firmly inserted into the main body of the distribution box, the first connecting piece is firmly connected to the fixed block, so the third flange is firmly clamped in the limiting hole; when it is necessary to pull out the fiber optic module cartridge from the main body of the distribution box, the user presses the reset member until the reset member presses the third flange to disengage the third flange from the limiting hole, reducing the possibility of uneven force application when the user presses the third flange, and using the reset member is time-saving and labor-saving, which can effectively improve work efficiency; then, the automatic reset of the spring drives the reset of the first connecting piece, the first connecting piece gradually releases the second connecting piece and the first connecting piece pushes the second connecting piece to slide, and the fiber optic module cartridge partially passes through the front opening, facilitating the quick extraction of the fiber optic module cartridge and improving work efficiency.

[0012] Preferably, a strip-shaped hole along the axial direction of the spring is provided on the side of the fixed block; the first connecting piece is provided with a limiting block; the limiting block is partially inserted into the strip-shaped hole.

[0013] By adopting the above technical solution, when it is necessary to pull out the fiber optic module cartridge, the automatic reset of the spring can drive the reset of the first connecting piece, and then the first connecting piece pushes the fiber optic module cartridge to partially pass through the front opening; during the process of the automatic reset of the spring driving the reset of the first connecting piece, the limiting block slides along the strip-shaped hole to the end of the length direction of the strip-shaped hole to block the sliding of the limiting block, effectively reducing the reset length of the spring, reducing the sliding distance of the first connecting piece pushing the fiber optic module cartridge, and thus reducing the possibility that the spring pushes too far and the fiber optic module cartridge slides off the main body of the distribution box, improving the safety of the fiber optic module cartridge.

[0014] Preferably, a guiding opening is provided on one side of the upper surface of the distribution box main body away from the fixing block; a guiding block matching the guiding opening is provided on one side of the upper surface of the optical fiber module insertion box away from the second connecting member.

[0015] By adopting the above technical solution, when the optical fiber module insertion box is inserted into the distribution box main body, during the process of the second connecting member pushing the first connecting member, the guiding block slides along the length direction of the guiding opening, thereby defining the insertion direction of the optical fiber module insertion box, enabling the optical fiber module insertion box to be inserted into the distribution box main body quickly and accurately, reducing the possibility of inaccurate insertion during the insertion process of the optical fiber module insertion box, thereby reducing the wear of the first connecting member and the second connecting member, and improving the service life of the distribution box and the optical fiber module insertion box; at the same time, reducing the possibility of the optical fiber module insertion box deviating in the insertion angle and causing collision with adjacent optical fiber module insertion boxes, and reducing the possibility of damage to the optical fiber cable.

[0016] Preferably, a sliding strip along the insertion direction of the optical fiber module insertion box is provided inside the distribution box main body; a guide rail matching the sliding strip is provided on the optical fiber module insertion box.

[0017] By adopting the above technical solution, during the process of the optical fiber module insertion box being inserted into the distribution box main body, the sliding strip is fitted into the guide rail. Therefore, the optical fiber module insertion box can slide along the sliding strip, further enabling the optical fiber module insertion box to be inserted into the distribution box main body quickly and accurately, effectively reducing the possibility of wear of the second connecting member and the first connecting member, while saving time and effort and improving work efficiency; then the optical fiber module insertion box slides along the sliding strip, further reducing the possibility of the optical fiber module insertion box deviating in the insertion process and causing adjacent optical fiber module insertion boxes to collide with each other, further improving the stability of the installation of the optical fiber module insertion box, reducing the possibility of damage to the optical fiber cable, and enabling the optical fiber module insertion box to work stably.

[0018] Preferably, one end of the sliding strip close to the front opening is conical.

[0019] By adopting the above technical solution, one end of the sliding strip close to the front opening is conical. When the optical fiber module insertion box is inserted into the distribution box main body, the conical sliding strip is more easily inserted into the guide rail, thereby reducing the possibility of the optical fiber module insertion box colliding with the sliding strip, and further reducing the possibility of damage to the sliding strip. Therefore, setting the port of the sliding strip to be conical can quickly insert the optical fiber module insertion box into the distribution box main body, saving time and effort and improving work efficiency.

[0020] Preferably, a handle is provided on one side of the optical fiber module insertion box away from the second connecting member.

[0021] By adopting the above technical solution, a handle is provided on the side of the fiber optic module plug-in box away from the second connecting member. When installing the fiber optic module plug-in box, the user can pinch the handle to push the fiber optic module plug-in box to move, reducing the possibility of the user directly contacting the outer wall of the fiber optic module plug-in box and causing pressure or even damage to the outer wall, thereby improving the safety of the fiber optic module plug-in box; after the spring automatically resets and drives the first connecting member to reset, so that the first connecting member pushes the fiber optic module plug-in box until the fiber optic module plug-in box partially passes through the front opening, the user can pinch the handle to drive the movement of the fiber optic module plug-in box, so that the user can quickly plug and unplug the fiber optic module plug-in box, saving time and effort and improving work efficiency.

[0022] Preferably, the outer surface of the handle is provided with anti-slip grooves.

[0023] By adopting the above technical solution, the outer surface of the handle is provided with anti-slip grooves. When the user pinches the handle to drive the optical fiber module box to slide, the anti-slip grooves can effectively reduce the possibility of the optical fiber module box sliding angle deviation, thereby reducing the collision of the optical fiber module box with the adjacent optical fiber module box during the plugging and unplugging process, and reducing the possibility of damage to the optical fiber cable; at the same time, the anti-slip grooves can effectively reduce the possibility of the optical fiber module box slipping, thereby improving the safety of the optical fiber module box.

[0024] Preferably, there are two handles; all the handles are arranged opposite to each other.

[0025] By adopting the above technical solution, two handles are provided, and all handles are arranged relative to each other; when the user plugs in or out the fiber optic module plug-in box, the user can pinch the two handles at the same time, which makes it easier for the user to apply force to the handles, thereby increasing the friction between the handles and the user's hands, further reducing the possibility of the fiber optic module plug-in box slipping, and thus enhancing the safety of the fiber optic module plug-in box; and by applying force to the two handles at the same time, the fiber optic module plug-in box is evenly stressed, making it easier to drive the fiber optic module plug-in box to slide, saving time and effort, and improving work efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the fiber optic module plug-in box is inserted into the wiring box body, the first connecting member is fixed by the cooperation of the third flange and the limiting hole. Then, the second connecting member is fixed to the first connecting member by the mutual cooperation of the first flange and the second flange. This makes the installation of the fiber optic module plug-in box more stable, reduces the possibility of adjacent fiber optic module plug-in boxes colliding with each other, and can effectively reduce the possibility of the fiber optic module plug-in box damaging the optical fiber cable, thereby maintaining the normal operation of the fiber optic module plug-in box.

[0028] 2. Insert the fiber optic module cartridge into the main body of the distribution box. The oppositely arranged limit strips can effectively enhance the stability of the fiber optic module cartridge installed in the main body of the distribution box, thereby reducing the collision between adjacent fiber optic module cartridges and further reducing the wear of the fiber optic cable.

[0029] 3. When it is necessary to pull the fiber optic module cartridge away from the main body of the distribution box, the user presses the reset member until the reset member presses against the third flange, causing the third flange to disengage from the limit hole, reducing the possibility of uneven force application when the user presses the third flange, and it is time-saving and labor-saving to use the reset member, which can effectively improve work efficiency; then, the automatic reset of the spring drives the reset of the first connecting member. The first connecting member gradually releases the second connecting member and pushes the second connecting member to slide, and a part of the fiber optic module cartridge passes through the front opening, facilitating the quick removal of the fiber optic module cartridge and improving work efficiency.

Detailed implementation mode

[0043] The following is a further detailed description of the present application in conjunction with the attached Figure 1-10 drawings.

[0044] Embodiment 1

[0045] The embodiment of the present application discloses a wiring box.

[0046] Referring to Figure 1 and Figure 2 , a wiring box for accommodating a highly modular optical fiber module cartridge 1 includes a wiring box body 2; a front opening 21 is provided on one side of the wiring box body 2 to facilitate the insertion of the optical fiber module cartridge 1 into the wiring box body 2 from the front opening 21; the wiring box body 2 is also provided with a back panel 22 opposite to the front opening 21, and a fixed block 23 is provided on the outer peripheral side of the wiring box body 2, and the fixed block 23 is installed on the back panel 22.

[0047] Referring to Figure 3 and Figure 4 , a connection groove 231 is provided on the side of the fixed block 23 close to the back panel 22, and the opening of the connection groove 231 penetrates through the back panel 22; then a spring 232 is provided at the bottom of the connection groove 231, one end of the spring 232 is connected to the connection groove 231, and a first connecting part 24 is installed at the other end, and the first connecting part 24 is partially inserted into the connection groove 231; a strip hole 235 along the axial direction of the spring 232 is provided on the fixed block 23, and a limit block 241 is provided on the first connecting part 24, and the limit block 241 is partially inserted into the strip hole 235 to limit the automatic reset length of the spring 232; a second connecting part 11 matching the first connecting part 24 is provided on the outer peripheral side of the optical fiber module cartridge 1 for being inserted into the first connecting part 24 to facilitate fixing the optical fiber module cartridge 1 to the wiring box body 2.

[0048] A limit strip 25 inclined towards the second connecting part 11 is provided at the end of the first connecting part 24 close to the second connecting part 11, a first flange 251 is provided on the side of the limit strip 25 close to the second connecting part 11, and a second flange 111 for matching and clamping with the first flange 251 is provided on the second connecting part 11; a third flange 252 is provided on the side of the limit strip 25 away from the second connecting part 11, and a limit hole 233 matching the third flange 252 is provided on the fixed block 23.

[0049] In the embodiment of the present application, taking two limiting strips 25 as an example, each limiting strip 25 is provided with a first flange 251 and a third flange 252. One limiting strip 25 is arranged on the upper surface of the first connecting piece 24, and the other limiting strip 25 is arranged on the lower surface of the first connecting piece 24. All the limiting strips 25 are inclined towards the second connecting piece 11. Therefore, the second connecting piece 11 is provided with two second flanges 111. One second flange 111 is arranged on the upper surface of the second connecting piece 11, and the other second flange 111 is arranged on the lower surface of the second connecting piece 11. Then, the fixing block 23 is provided with two limiting holes 233. All the limiting holes 233 are arranged in one-to-one correspondence with the third flanges 252. A reset member 234 is arranged on one side of each limiting hole 233 away from the first connecting piece 24.

[0050] Therefore, when the optical fiber module cartridge 1 is inserted into the distribution box body 2, the optical fiber module cartridge is pushed until the second connecting piece 11 abuts against the first connecting piece 24, causing the first connecting piece 24 to move towards the bottom of the connecting groove 231. At the same time, the first connecting piece 24 compresses the spring 232, so that the spring 232 is compressed. Then, the first connecting piece 24 slides until both third flanges 252 are partially inserted into the corresponding limiting holes 233, that is, the first connecting piece 24 is fixed, which can further enhance the stability of the installation of the first connecting piece 24. During the process of the second connecting piece 11 pushing the first connecting piece 24 to slide, the notch of the connecting groove 231 forces both limiting strips 25 to incline towards the second connecting piece 11. Then, after the first connecting piece 24 is fixed, the first flange 251 on the upper surface of the limiting strip 25 will block the movement of the second flange 111 on the upper surface of the second connecting piece 11, and the first flange 251 on the lower surface of the limiting strip 25 will block the second flange 111 on the lower surface of the second connecting piece 11, thereby fixing the second connecting piece 11, making the installation of the optical fiber module cartridge 1 more stable, reducing the possibility of adjacent optical fiber module cartridges 1 colliding with each other, effectively reducing the possibility of optical fiber cables being damaged, and maintaining the normal operation of the optical fiber module cartridge 1.

[0051] When the optical fiber module cartridge 1 needs to be detached from the distribution box body 2, the user can simultaneously press the two reset members 234. The reset members 234 press the third flanges 252, so that the third flanges 252 are detached from the limiting holes 233. Then, the automatic reset of the spring 232 drives the automatic reset of the first connecting piece 24, thereby pushing the second connecting piece 11 to move, and the limiting strips 25 will also gradually reset. Thus, the second flange 111 moves away from the first flange 251. Therefore, the first connecting piece 24 releases the second connecting piece 11, and at the same time, the first connecting piece 24 partially pushes the optical fiber module cartridge 1 out of the distribution box body 2, facilitating the user to quickly pull out the optical fiber module cartridge 1 from the distribution box body 2, saving time and effort and improving work efficiency.

[0052] Refer to Figure 1, the wiring box body 2 is provided with a guiding port 26, and the optical fiber module insertion box 1 is provided with a guiding block 12 that matches the guiding port 26. In the embodiment of the present application, taking 2 guiding ports 26 and 2 guiding blocks 12 as an example, one guiding port 26 is arranged on one side of the upper surface of the wiring box body 2 away from the backplane 22, and the other guiding port 26 is arranged on one side of the lower surface of the wiring box body 2 away from the backplane 22. The guiding blocks 12 are arranged in one-to-one correspondence with the guiding ports 26. Therefore, during the process of inserting the optical fiber module insertion box 1 into the wiring box body 2, all the guiding blocks 12 simultaneously slide along the length direction of the corresponding guiding ports 26, thereby limiting the insertion direction of the optical fiber module insertion box 1 inside the wiring box body 2, enabling the optical fiber module insertion box 1 to be inserted into the wiring box body 2 quickly and accurately, thus reducing the wear of the first connecting member 24 and the second connecting member 11 caused by inaccurate insertion, and improving the service life of the wiring box and the optical fiber module insertion box 1; at the same time, reducing the possibility of the insertion angle deviation of the optical fiber module insertion box 1 causing collision with adjacent optical fiber module insertion boxes 1, and reducing the possibility of the optical fiber module insertion box 1 wearing the optical fiber cable.

[0053] Refer to Figure 3 , a handle 14 is provided on one side of the optical fiber module insertion box 1 away from the second connecting member 11, and the handle 14 is provided with anti-slip lines 141, which is convenient for the user to quickly insert and remove the optical fiber module insertion box 1, and can effectively reduce the possibility of the optical fiber module insertion box 1 slipping off; in the embodiment of the present application, taking 2 handles 14 as an example, one handle 14 is arranged on the upper surface of the optical fiber module insertion box 1, and the other handle 14 is arranged on the lower surface of the optical fiber module insertion box 1, and the 2 handles 14 are arranged oppositely, which is convenient for the user to hold all the handles 14 simultaneously, making the force on the optical fiber module insertion box 1 uniform, so that the user can quickly push the optical fiber module insertion box 1, further reducing the possibility of the optical fiber module insertion box 1 slipping off.

[0054] Refer to Figure 5 , the optical fiber module insertion box 1 is provided with a receiving groove 16 and a cable management ring 17. The receiving groove 16 is arranged on one side of the optical fiber module insertion box 1, and the cable management ring 17 is arranged around the outer peripheral side of the receiving groove 16, and the receiving groove 16 is communicated with the cable management ring 17, which is convenient for combing the optical fiber cable, improving the convenience of optical fiber cable arrangement, and at the same time can store the redundant optical fiber cable, improving the convenience of cable management; and by receiving and combing the optical fiber cable, it can effectively reduce the possibility of the optical fiber cable protruding too much and the optical fiber module insertion box 1 wearing the optical fiber cable, and improving the stability of the normal use of the optical fiber module insertion box 1.

[0055] The implementation principle of a distribution box in an embodiment of the present application is as follows: During the process of inserting the optical fiber module cartridge 1 into the distribution box main body 2, through the clamping connection between the third flange 252 and the limiting hole 233 and the cooperation and block between the first flange 251 and the second flange 111, the first connecting member 24 is stably installed on the fixed block 23, and the second connecting member 11 is stably installed on the first connecting member 24, thereby reducing the mutual collision between adjacent optical fiber module cartridges 1 and reducing the possibility of optical fiber cable abrasion.

[0059] A slide bar 27 along the sliding direction of the optical fiber module cartridge 1 is provided inside the distribution box main body 2, and the optical fiber module cartridge 1 is provided with a guide rail 13 matching the slide bar 27. Through the mutual engagement between the slide bar 27 and the guide rail 13, the optical fiber module cartridge 1 can be quickly inserted into the distribution box main body 2, reducing the possibility of angular deviation of the optical fiber module cartridge 1 during the sliding process, thereby reducing the possibility of optical fiber cable abrasion; at the same time, one side of the slide bar 27 close to the front opening 21 is conical, which is convenient for the slide bar 27 to be quickly inserted into the guide rail 13, saving time and effort, improving work efficiency, and reducing the possibility of collision between the optical fiber module cartridge 1 and the slide bar 27, improving the protection level of the optical fiber module cartridge 1.

[0068] Referring to Figure 10 , based on Embodiment 1, the main difference between the embodiment of the present application and Embodiment 1 is that the embodiment of the present application is provided with a guiding member 15 and a guiding groove 291 for guiding the insertion of the optical fiber module plug-in box 1, specifically as follows:

[0069] A guiding member 15 is provided on one side of the optical fiber module plug-in box 1 close to the second connecting member 11.
