[0001] The present invention relates to the technical field of communication equipment, and in particular to an optical cable junction box and an opening and closing method thereof. Background Art

[0002] Fiber optic splice closures are essential devices for connecting and protecting fiber optic cable splices. Existing closures, such as Patent No. CN115308857A, offer ease of installation and include a closure body, an upper housing, a lower housing, and locking devices positioned between the left and right sides of the upper and lower housings. During installation and maintenance, manual sealing is required, which is complex and prone to leaking seals, potentially leading to moisture or damage to the fiber optic cable splices. Summary of the Invention

[0003] The purpose of the invention is to provide an optical cable splice box and an opening and closing method thereof, which solve the problems of difficult sealing and loose sealing of optical cable splice boxes in the prior art.

[0004] The present invention is implemented as follows: an optical cable junction box includes a first box body and a second box body that can be opened and closed and sealed with the first box body, a wire feed groove is provided at the end of the first box body and / or the second box body, a locking member for limiting the optical cable is provided in the first box body or the second box body, the first box body and the second box body are rotatably connected, a driving mechanism is provided between the wire feed groove and the locking member, the driving mechanism is communicatively connected to a control unit, the driving mechanism is actuated to open and close the first box body and the second box body, and the driving mechanism can avoid the optical cable.

[0005] The first box body and the second box body are rotationally connected, and the limiting function can be achieved by the rotating shaft between the first box body and the second box body. Therefore, when the first box body and the second box body are closed, fast and accurate closure can be achieved without positioning, thereby ensuring the airtightness of the junction box. At the same time, considering that manual operation is relatively troublesome, but the automatic closing of the junction box has the problem of limited internal space of the junction box and the need for the optical cable to pass through and easily interfere, the present invention arranges the driving mechanism between the wire feed trough and the locking member, and the optical cable shuttles linearly between the wire feed trough and the locking member. The range of optical cables that the driving mechanism needs to avoid when operating is relatively small and easy. The automatic opening and closing of the junction box can be achieved through the present invention, which not only improves efficiency but also has good sealing.

[0006] A further technical solution of the present invention is: the driving mechanism includes a driving motor and a transmission assembly, the driving motor is placed in the first box body, one end of the transmission assembly is movably connected to the inner wall of the first box body and the other end is movably connected to the second box body, and the driving motor drives the transmission assembly to open or fold for opening and closing the junction box.

[0007] The driving motor is inside the first box body, and one end of the transmission component is rotationally connected to the inner wall of the first box body and the other end is rotationally connected to the second box body. When the transmission component is powered by the driving motor, the transmission component opens or folds, thereby opening or closing the first box body and the second box body, thereby realizing the opening and closing of the junction box; during the opening process of the transmission component, the space between the first box body and the second box body gradually increases, and the transmission component can avoid interference with the optical cable. Moreover, when the transmission component is folded, the first box body and the second box body component are closed, which also does not affect the shuttling of the optical cable. Not only can the automatic opening and closing of the junction box be realized, but also interference with the optical cable can be avoided.

[0008] A further technical solution of the present invention is: the transmission assembly includes a first connecting member and a second connecting member, one end of the first connecting member is rotatably connected to the first box body, the other end of the first connecting member is rotatably connected to one end of the second connecting member, and the other end of the second connecting member is rotatably connected to the second box body.

[0009] When in use, the first connecting member is rotatably connected to the first box body, and the first connecting member is rotatably connected to the second connecting member. During the closing process of the first box body and the second box body, the first connecting member and the second connecting member can be rotated so that the angle gradually decreases, avoiding the optical cable from above or below; when the first box body and the second box body are opened, the first connecting member and the second connecting member gradually open to the end away from the optical cable, which can also avoid the optical cable.

[0010] A further technical solution of the present invention is that the first connecting member and the second connecting member are rotatably connected via a rotating shaft, and the rotating shaft can slide along the output end of the driving motor to adjust the angle between the first connecting member and the second connecting member.

[0011] When the first box body and the second box body need to be opened, the driving motor drives the rotating shaft to move along the output end of the driving motor toward the hinged end of the first box body and the second box body. During the gradual opening process, the junction box opens without interfering with the optical cable; when the first box body and the second box body need to be closed, the driving motor drives the rotating shaft to move along the output end of the driving motor toward the opening and closing end of the first box body and the second box body, the first connecting member and the second connecting member are gradually folded, and the junction box is closed without interfering with the optical cable.

[0012] A further technical solution of the present invention is that the first connecting member and the second connecting member are both arc-shaped structures.

[0013] The curved structure is conducive to space utilization and avoiding optical cables.

[0014] A further technical solution of the present invention is that the drive motor is placed in the first box body and below the connecting section between the wire feed slot and the locking member, and the transmission assembly can avoid the connecting section between the wire feed slot and the locking member when it moves.

[0015] The connecting section between the cable entry trough and the locking piece is for the optical cable to pass through. The drive motor is located below the connecting section to avoid interference with the optical cable. At the same time, when the drive motor activates the transmission assembly, the transmission assembly can be easily stored below the optical cable.

[0016] A further technical solution of the present invention is: a driving mechanism is provided on one side of the first box body, and a transmission assembly is provided between the wire feed groove and the locking member on the other side of the first box body, one end of the transmission assembly is rotatably connected to the inner wall of the first box body, and the other end is rotatably connected to the second box body.

[0017] Ensure the stability of the first box body and the second box body when opening and closing.

[0018] A further technical solution of the present invention is that the first box body is hinged to one side of the second box body, and the first box body and the second box body are disengageable on the other side through a locking mechanism.

[0019] The first box body and the other end of the second box body can be disengaged through a locking mechanism, further ensuring the tightness and stability of the joint box.

[0020] A further technical solution of the present invention is: the locking mechanism includes a lock buckle and a lock tongue, the lock buckle can be disengaged from the lock tongue through a magnetic switch, and the magnetic switch is communicatively connected to the control unit.

[0021] When the junction box needs to be opened, the control unit receives an opening signal, and the control unit energizes the magnetic switch. The lock is separated from the lock tongue under the action of the magnetic switch, and the driving structure cooperates to realize the opening of the junction box; otherwise, the control unit deenergizes the magnetic switch, and the lock is locked with the lock tongue.

[0022] The present invention also provides a method for opening and closing an optical cable junction box, wherein the junction box is the above-mentioned junction box, and the method comprises the following steps: a control unit receives a signal, the control unit sends a switch instruction to a driving mechanism, the driving mechanism is actuated, and the first box body and the second box body rotate to open or close.

[0023] Beneficial effects of the present invention: The junction box of the present invention realizes automatic sealing of the optical cable junction box through the cooperation of the first box body, the second box body and the driving mechanism. It is simple to operate and has a good sealing effect. It effectively prevents the optical cable joint from being damp or damaged, and improves the reliability and service life of the optical cable junction box.

[0024] The first box body and the second box body are rotationally connected, and the limiting function can be achieved by the rotating shaft between the first box body and the second box body. Therefore, when the first box body and the second box body are closed, fast and accurate closure can be achieved without positioning, thereby ensuring the airtightness of the junction box. At the same time, considering that manual operation is relatively troublesome, but the automatic closing of the junction box has the problem of limited internal space of the junction box and the need for the optical cable to pass through and easily interfere, the present invention arranges the driving mechanism between the wire feed trough and the locking member, and the optical cable shuttles linearly between the wire feed trough and the locking member. The range of optical cables that the driving mechanism needs to avoid when operating is relatively small and easy. The automatic opening and closing of the junction box can be achieved through the present invention, which not only improves efficiency but also has good sealing. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0037] Example 1:

[0038] Figure 1-5 An optical cable junction box is shown, comprising a first box body 1 and a second box body 2 that can be opened and closed and sealed with the first box body 1. A wire feed groove 5 is provided at the end of the first box body 1 and / or the second box body 2. A locking member 6 for limiting the optical cable is provided in the first box body 1 or the second box body 2. The first box body 1 and the second box body 2 are rotatably connected. A driving mechanism 3 is provided between the wire feed groove 5 and the locking member 6. The driving mechanism 3 is communicatively connected to a control unit 4. The driving mechanism 3 is actuated to open and close the first box body 1 and the second box body 2. The driving mechanism 3 can avoid the optical cable when it is actuated.

[0039] The first box body and the second box body are rotationally connected, and the limiting function can be achieved by the rotating shaft between the first box body and the second box body. Therefore, when the first box body and the second box body are closed, fast and accurate closure can be achieved without positioning, thereby ensuring the airtightness of the junction box. At the same time, considering that manual operation is relatively troublesome, but the automatic closing of the junction box has the problem of limited internal space of the junction box and the need for the optical cable to pass through and easily interfere, the present invention arranges the driving mechanism between the wire feed trough and the locking member, and the optical cable shuttles linearly between the wire feed trough and the locking member. The range of optical cables that the driving mechanism needs to avoid when operating is relatively small and easy. The automatic opening and closing of the junction box can be achieved through the present invention, which not only improves efficiency but also has good sealing.

[0040] In this embodiment, a sealing layer is provided on the surface of the second box body 2 that contacts the first box body 1 .

[0041] In this embodiment, a semicircular wire feed groove 5 is provided on both the first box body 1 and the second box body 2 . The power end of the driving mechanism 3 is provided in the first box body 1 , and the action end of the driving mechanism 3 is rotationally connected to the second box body 2 .

[0042] In this embodiment, the optical cable passes through the cable entry duct 5 into the junction box and is fixed in the junction box by the locking member 6 .

[0043] In this embodiment, the driving mechanism 3 includes a driving motor 31 and a transmission assembly 32. The driving motor 31 is placed in the first box body 1. One end of the transmission assembly 32 is movably connected to the inner wall of the first box body 1 and the other end is movably connected to the second box body 2. The driving motor 31 drives the transmission assembly 32 to open or fold for opening and closing the junction box.

[0044] The driving motor is inside the first box body, and one end of the transmission component is rotationally connected to the inner wall of the first box body and the other end is rotationally connected to the second box body. When the transmission component is powered by the driving motor, the transmission component opens or folds, thereby opening or closing the first box body and the second box body, thereby realizing the opening and closing of the junction box; during the opening process of the transmission component, the space between the first box body and the second box body gradually increases, and the transmission component can avoid interference with the optical cable. Moreover, when the transmission component is folded, the first box body and the second box body component are closed, which also does not affect the shuttling of the optical cable. Not only can the automatic opening and closing of the junction box be realized, but also interference with the optical cable can be avoided.

[0046] When in use, the first connecting member is rotatably connected to the first box body, and the first connecting member is rotatably connected to the second connecting member. During the closing process of the first box body and the second box body, the first connecting member and the second connecting member can be rotated so that the angle gradually decreases, avoiding the optical cable from above or below; when the first box body and the second box body are opened, the first connecting member and the second connecting member gradually open to the end away from the optical cable, which can also avoid the optical cable.

[0047] In this embodiment, in order to further reduce space occupation, the first connecting member 321 and the second connecting member 322 are both sheet-like structures.

[0048] In this embodiment, the first connecting member 321 and the second connecting member 322 are rotatably connected via a rotating shaft 323 . The rotating shaft 323 can slide along the output end of the driving motor 31 to adjust the angle between the first connecting member 321 and the second connecting member 322 .

[0049] When the first box body and the second box body need to be opened, the driving motor drives the rotating shaft to move along the output end of the driving motor toward the hinged end of the first box body and the second box body. During the gradual opening process, the junction box opens without interfering with the optical cable; when the first box body and the second box body need to be closed, the driving motor drives the rotating shaft to move along the output end of the driving motor toward the opening and closing end of the first box body and the second box body, the first connecting member and the second connecting member are gradually folded, and the junction box is closed without interfering with the optical cable.

[0050] In this embodiment, the output end of the driving motor 31 includes a motor shaft and a screw rod. The rotating shaft 323 is sleeved on the screw rod. When the screw rod rotates, the rotating shaft 323 moves along the axial direction of the screw rod.

[0051] In this embodiment, both the first connecting member 321 and the second connecting member 322 are arc-shaped structures.

[0052] The curved structure is conducive to space utilization and avoiding optical cables.

[0053] In this embodiment, the driving motor 31 is placed in the first box body 1 and below the connecting section between the wire feed slot 5 and the locking member 6 , and the transmission assembly 32 can avoid the connecting section between the wire feed slot 5 and the locking member 6 when it moves.

[0054] The connecting section between the cable entry trough and the locking piece is for the optical cable to pass through. The drive motor is located below the connecting section to avoid interference with the optical cable. At the same time, when the drive motor activates the transmission assembly, the transmission assembly can be easily stored below the optical cable.

[0055] In this embodiment, one end of the transmission assembly 32 is below the output end of the driving motor 31 and is rotatably connected to the first box body 1 , and the other end of the transmission assembly 32 is rotatably connected to the second box body 2 .

[0056] In this embodiment, a driving mechanism 3 is provided on one side of the first box body 1, and a transmission assembly 32 is provided between the wire feed groove 5 and the locking member 6 on the other side of the first box body 1. One end of the transmission assembly 32 is rotatably connected to the inner wall of the first box body 1, and the other end is rotatably connected to the second box body 2.

[0057] Ensure the stability of the first box body and the second box body when opening and closing.

[0058] In this embodiment, the driving motor 31 is rotationally connected to the first box body 1 .

[0059] In this embodiment, one side of the first box body 1 is hinged to the second box body 2 , and the other side of the first box body 1 and the second box body 2 can be disengaged through a locking mechanism 7 .

[0060] The first box body and the other end of the second box body can be disengaged through a locking mechanism, which further ensures the tightness and stability of the joint box.

[0061] In this embodiment, the locking mechanism 7 includes a lock buckle 71 and a lock tongue 72 . The lock buckle 71 can be disengaged from the lock tongue 72 via a magnetic switch 73 . The magnetic switch 73 is in communication with the control unit 4 .

[0062] When the junction box needs to be opened, the control unit receives an opening signal, and the control unit energizes the magnetic switch. The lock is separated from the lock tongue under the action of the magnetic switch, and the driving structure cooperates to realize the opening of the junction box; otherwise, the control unit deenergizes the magnetic switch, and the lock is locked with the lock tongue.

[0063] In this embodiment, the lock buckle 71 is U-shaped and is rotatably connected to the inner wall of the first box body 1, and the magnetic switch 73 is placed between the lock buckle 71 and the inner wall of the first box body 1; the lock tongue 72 is provided on the second box body 2. When the magnetic switch 73 is energized, the lock buckle 71 rotates to disengage from the lock tongue 72, and conversely, the lock buckle 71 rotates to lock with the lock tongue 72.

[0064] In this embodiment, the locking mechanism 7 is placed on the inner side of the front surface of the junction box.

[0065] Example 2:

[0066] like Figure 1-7 The method for opening and closing an optical cable junction box includes the following steps: a control unit 4 receives a signal, the control unit 4 sends a switch instruction to a driving mechanism 3, the driving mechanism 3 is actuated, and the first box body 1 and the second box body 2 rotate to open or close.

[0067] In this embodiment, the system management platform or the mobile phone terminal enables the control unit 4 to receive a signal through any one of remote control, Bluetooth and QR code, and then the control unit 4 issues an unlocking instruction according to the received signal. The locking structure 7 triggers the magnetic switch 73 on the lock buckle 71 according to the instruction, so that the lock buckle 71 is disengaged from the lock tongue 72, and then the driving mechanism 3 drives the transmission assembly 32 to start through the driving motor 31, thereby realizing the relative movement of the first box body 1 and the second box body 2, and the junction box is opened.

[0068] In this embodiment, the system management platform or the mobile phone terminal enables the control unit 4 to receive a signal through any one of remote control, Bluetooth and QR code, and then the control unit 4 issues a locking instruction according to the received signal, and the driving mechanism 3 drives the transmission component 32 to fold through the driving motor 31, and then the locking structure 7 triggers the magnetic switch 73 on the lock buckle 71 according to the instruction, so that the lock buckle 71 and the lock tongue 72 are locked, realizing the relative movement of the first box body 1 and the second box body 2, and the junction box is closed.

[0069] In this embodiment, the splice box of the present invention includes a first box body 1 , a second box body 2 , a driving mechanism 3 , and a control unit 4 .

[0070] The first box body 1 is used to accommodate the optical cable connector, on which the driving mechanism 3, the control unit 4 and the lock 71 are installed.

[0071] The second box body 2 includes a sealing cover and a sealing ring. The sealing cover is movably mounted on the first box body 1 to cover the opening of the first box body. The sealing ring is positioned between the sealing cover and the box body to ensure a good seal. The sealing cover and the first box body 1 are connected by a rotating shaft for rotational opening and closing. The sealing ring is positioned between the sealing cover and the first box body 1 to ensure a good seal.

[0072] The driving mechanism 3 includes a driving motor 31 and a transmission assembly 32. The driving motor 31 provides power, and the transmission assembly 32 transmits the power of the motor 31 to the sealing cover to enable it to open and close.

[0073] Control unit 4: includes a sensor, a control unit, and a magnetic switch. The sensor detects the environmental parameters inside the junction box, and the control unit controls the operating state of the drive motor based on the sensor's detection results and instructions issued by the system management platform.

[0074] Sensor: set in the first box body to detect environmental parameters such as humidity and temperature in the junction box;

[0075] Control unit: connected to the sensor and drive motor, and controls the working state of the drive motor according to the detection results of the sensor.

[0076] Limit switch: placed on the first box body to detect whether the opening and closing positions of the junction box are in place.

[0077] Working principle of the present invention:

[0078] The first box body 1 can be opened and closed in three ways: remotely through the system management platform; via mobile phone Bluetooth; or via a QR code on the first box body 1. When the system management platform detects that the humidity inside the first box body 1 exceeds a preset value or the system detects a communication failure, the system management platform will send a maintenance work order to the corresponding maintenance personnel's mobile phone. After the maintenance personnel arrive at the site, they can establish a connection with the control unit in the junction box and obtain authorization through the above three methods. First, they control the lock 71 to open. When the magnetic switch 73 is activated, it indicates that the lock has reached the fully opened state. Then, they control the drive motor 31 to start, drive the sealing cover to open to a certain angle through the transmission assembly 32, and then control the drive motor 31 to stop, thereby opening the first box body 1 and performing equipment inspection and maintenance. When the control unit receives a closing command sent by the system management platform or mobile phone Bluetooth, the control unit controls the drive motor 31 to start in the reverse direction, drives the sealing cover to close through the transmission assembly 32, and controls the drive motor 31 to stop when the magnetic switch 73 is activated.

[0079] The present invention discloses an optical cable splice closure comprising a first housing, a second housing, a drive mechanism, and a control unit. The second housing is mounted on the first housing and automatically seals the first housing; the drive mechanism is connected to the second housing and drives the second housing to perform a sealing operation; and the control unit is connected to the drive mechanism and controls the operating state of the drive mechanism. The automatic sealing system of the optical cable splice closure of the present invention is simple to operate and provides effective sealing, effectively preventing moisture or damage to the optical cable splices, and improving the reliability and service life of the optical cable splice closure.
