Description

Technical Field

[0001] The present invention relates to the technical field of optical communications, and in particular to a floating docking optical fiber adapter. Background Art

[0002] In the existing technology, the use of fiber pigtail cable storage boxes can barely solve the problem of unreasonable storage of redundancy. However, in order to solve the redundant storage problem, a certain amount of space is sacrificed. During on-site construction, the wiring efficiency is not high, and the economic efficiency can be further improved.

[0003] There is a pull-out optical fiber distribution box in the prior art, but this type of distribution box has problems such as low access accuracy and poor contact of the optical fiber interface, which reduces the wiring efficiency. Summary of the Invention

[0004] The problem solved by the present invention is that the optical fiber interfaces in the pull-out optical fiber distribution box in the prior art are difficult to connect accurately.

[0005] To address the above-mentioned issues, the present invention provides a floating docking fiber optic adapter, comprising a wiring box and a wiring cassette. The wiring box is provided with a first guide surface; the wiring cassette is detachably connected to the wiring box; the wiring box is provided with an opening for access; the wiring box is provided with a first guide member, one end of which is fixedly connected to the first guide surface; the wiring cassette is provided with a first guide position; the first guide member extends toward the opening, and the first guide member and the first guide position cooperate.

[0006] Compared with the existing technology, the technical effect achieved by this technical solution is: the wiring box can be pulled out from the wiring box through the opening, and when the manual operation of the optical cable is completed, the wiring box is pushed back into the wiring box. When the wiring box is not fully pushed into the wiring box, the first guide piece can cooperate with the first guide position, which can effectively limit the displacement of the wiring box and guide the wiring box to move along the first guide piece, so that the optical fiber interface on the wiring box can accurately enter the connection position when the wiring box is pushed back, without the need for multiple push-pull adjustments, thereby improving the access efficiency of the optical fiber interface.

[0007] Furthermore, a second guide position is provided on the wiring box body, and the wiring box is provided with a second guide surface and a second guide member; one end of the second guide member is fixedly connected to the second guide surface; the second guide member extends away from the opening, and the second guide member cooperates with the second guide position; the first guide surface and the second guide surface are arranged opposite to each other.

[0008] Compared to existing technologies, this technical solution achieves the following technical advantages: When the wiring cassette is not fully inserted into the wiring cabinet, the second guide member can engage with the second guide position to guide the movement of the wiring cassette along the second guide member. The second guide member further limits the displacement of the wiring cassette, enabling more accurate positioning of the fiber optic interface. The first guide surface and the second guide surface are arranged opposite each other, ensuring that the first guide member can engage with the first guide position and the second guide member can engage with the second guide position.

[0009] Furthermore, an end of the first guide member close to the opening and an end of the second guide member away from the opening are both provided with a guide structure.

[0010] Compared with the existing technology, the technical effect achieved by this technical solution is: the guide structure is arranged at the end, which can guide the first guide member into the first guide position and the second guide member into the second guide position. Even if the position of the wiring box deviates during the process of pushing the wiring box back, the guide member can smoothly enter the corresponding guide position through the guide structure, ensuring that the first guide member and the second guide member can correctly guide the wiring box.

[0011] Furthermore, the floating docking optical fiber adapter also includes a first connector; a first mounting position is provided on the distribution box; and the first connector cooperates with the first mounting position.

[0012] Compared with the existing technology, the technical effect achieved by this technical solution is that the end of the first connector close to the wiring box is used to connect to the optical fiber inside the wiring box, and the other end is used to connect to the external optical fiber. The first connector cooperates with the first mounting position to achieve the connection between the first connector and the wiring box.

[0013] Furthermore, a first retaining structure is provided on the first connecting member; a second retaining structure is provided in the first installation position; and the first retaining structure and the second retaining structure are in abutment with each other.

[0014] Compared with the existing technology, the technical effect achieved by this technical solution is: limiting the first connecting part to prevent the first connecting part from moving in the first installation position when the distribution box is pulled out or pushed back, thereby avoiding the displacement of the optical fiber interface and causing the optical fiber to be unable to be accurately connected.

[0015] Furthermore, the wiring box is provided with a limiter, which can rotate relative to the wiring box, and the limiter has a first angular phase and a second angular phase; the wiring box body is provided with a limit slot; When the limiting member rotates to the first angular phase, the limiting member is engaged with the limiting groove; when the limiting member is at the second angular phase, the limiting member is released from engaging with the limiting groove.

[0016] Compared to the existing technology, this technical solution achieves the following technical effects: when the stopper is rotated to the first angular phase, the stopper engages with the stopper slot, preventing the wiring box from being withdrawn from the wiring box; when the stopper is rotated to the second angular phase, the stopper and the stopper slot disengage, allowing the wiring box to be withdrawn from the wiring box. The stopper locks the wiring box in place, preventing it from detaching from the wiring box without manual operation, thus ensuring the stability of the fiber optic interface connection.

[0017] Furthermore, the wiring box is provided with a second installation position and a clamping portion; the limiting member cooperates with the second installation position and is clamped with the clamping portion.

[0018] Compared to the existing technology, this technical solution achieves the following technical effects: the limiter fits in the second installation position, and one end of the limiter extends out of the wiring box, facilitating manual twisting. The limiter rotates in the second installation position, and the clamping portion is provided in the wiring box to secure the end of the limiter that does not extend out of the wiring box, allowing the limiter to rotate stably.

[0019] Furthermore, the floating docking optical fiber adapter also includes a second connector, which is fixedly connected to the wiring box; the first connector is plugged into one end of the second connector, and the other end of the second connector is used to connect to an external optical fiber.

[0020] Compared with the existing technology, the technical effect achieved by this technical solution is: the second connecting piece is fixedly connected to the wiring box, so that the second connecting piece is located in a fixed position. When the wiring box is pushed back into the wiring box, the first connecting piece can be plugged into the second connecting piece to realize the access of the optical fiber interface.

[0021] Furthermore, a bypass socket is fixedly connected to the wiring box, and the bypass socket is communicatively connected to the second connector.

[0022] Compared with the existing technology, the technical effect achieved by this technical solution is: the bypass socket is communicatively connected to the second connector via an optical fiber cable, and the bypass socket is used to access an external optical fiber cable.

[0023] Furthermore, there is a accommodating space in the distribution box, and at least one winding piece is provided in the accommodating space, and the winding piece is used to wind the redundant optical fiber; at least one stop structure is provided on the winding piece to prevent the redundant optical fiber from escaping from the accommodating space.

[0024] Compared with the existing technology, the technical effect achieved by this technical solution is: the winding member and the stop structure can realize the reasonable arrangement of redundant optical fibers, prevent the redundant optical fibers from being entangled, and facilitate manual operation.

DETAILED DESCRIPTION

[0027] The object of the present invention is to provide a floating docking optical fiber adapter for improving the connection accuracy of optical fiber interfaces and improving wiring efficiency.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] See also Figures 1 to 5The present invention provides a floating docking optical fiber adapter, comprising a wiring box 1 and a wiring cassette 2. The wiring box 1 is provided with a first guide surface 10; the wiring cassette 2 is detachably connected to the wiring box 1; the wiring box 1 is provided with an opening 11 for access to the wiring cassette 2; the wiring box 1 is provided with a first guide member 12, one end of which is fixedly connected to the first guide surface 10; the wiring cassette 2 is provided with a first guide position 22; the first guide member 12 extends toward the opening 11, and the first guide member 12 and the first guide position 22 cooperate.

[0030] Preferably, the wiring box 1 is further provided with supporting ribs along the inner wall, and the supporting ribs can divide the space inside the wiring box 1 into two layers, so that more wiring boxes 2 can be installed.

[0031] Preferably, the first guide member 12 is a cylinder, and the first guide position 22 is a circular hole.

[0032] The wiring box 2 can be pulled out from the wiring box 1 through the opening 11. When the manual operation of the optical cable is completed, the wiring box 2 is pushed back into the wiring box 1. When the wiring box 2 is not completely pushed into the wiring box 1, the first guide member 12 can cooperate with the first guide position 22, which can effectively limit the displacement of the wiring box 2 and guide the wiring box 2 to move along the first guide member 12, so that the optical fiber interface on the wiring box 2 can accurately enter the connection position when the wiring box 2 is pushed back, without the need for multiple push-pull adjustments, thereby improving the access efficiency of the optical fiber interface.

[0033] Reference Figure 3 、 Figure 4 and Figure 5 A second guide position 13 is provided on the wiring box body 1, and the wiring box 2 is provided with a second guide surface 20 and a second guide member 21; one end of the second guide member 21 is fixedly connected to the second guide surface 20; the second guide member 21 extends away from the opening 11, and the second guide member 21 cooperates with the second guide position 13; the first guide surface 10 and the second guide surface 20 are arranged opposite to each other.

[0034] Preferably, the second guide member 21 is a cylinder, and the second guide position 13 is a circular hole.

[0035] When the wiring box 2 is not fully inserted into the wiring cabinet 1, the second guide member 21 can cooperate with the second guide position 13 to guide the movement of the wiring box 2 along the second guide member 21. The second guide member 21 further limits the displacement of the wiring box 2, enabling more accurate positioning of the optical fiber interface. The first guide surface 10 and the second guide surface 20 are arranged relative to each other, ensuring that the first guide member 12 can cooperate with the first guide position 22 and the second guide member 21 can cooperate with the second guide position 13.

[0036] Refer again Figure 3 and Figure 5The end of the first guide member 12 close to the opening 11 and the end of the second guide member 21 away from the opening 11 are both provided with a guide structure 23.

[0037] Specifically, the guide structure 23 is an inclined surface provided at the end of the first guide member 12 and the second guide member 21. The guide structure 23 is distributed circumferentially along the first guide member 12 and the second guide member 21, so that the end of the first guide member 12 and the second guide member 21 are truncated cone-shaped, and the end of the truncated cone on the first guide member 12 with a smaller diameter is the end away from the first guide surface 10, and the end of the truncated cone on the second guide member 21 with a smaller diameter is the end away from the second guide surface 20.

[0038] The guide structure 23 is provided at the end, which can guide the first guide member 12 into the first guide position 22 and the second guide member 21 into the second guide position 13. Even if the position of the wiring box 2 deviates during the pushing back process, the guide member can smoothly enter the corresponding guide position through the guide structure 23, ensuring that the first guide member 12 and the second guide member 21 can correctly guide the wiring box 2.

[0039] like Figures 7 to 10 As shown, the floating docking optical fiber adapter further includes a first connector 3 ; a first mounting position 24 is provided on the distribution box 2 ; and the first connector 3 cooperates with the first mounting position 24 .

[0040] The first connector 3 is connected to the wiring box 2 at one end thereof and to the external optical fiber at the other end thereof.

[0041] A first retaining structure 31 is provided on the first connecting member 3 ; a second retaining structure 241 is provided in the first installation position 24 ; the first retaining structure 31 and the second retaining structure 241 are in contact with each other.

[0042] The first retaining structure 31 and the second retaining structure 241 abut against each other to limit the first connector 3 and prevent the first connector 3 from moving in the first installation position 24 when the distribution box 2 is pulled out or pushed back, thereby avoiding displacement of the optical fiber interface and causing the optical fiber to be unable to be accurately connected.

[0043] Refer again Figure 2 and Figure 4 The wiring box 2 is also provided with a limit member 4, which can rotate relative to the wiring box 2, and the limit member 4 has a first angular phase and a second angular phase; the wiring box body 1 is provided with a limit groove 14; when the limit member 4 rotates to the first angular phase, the limit member 4 cooperates with the limit groove 14; when the limit member 4 rotates to the second angular phase, the limit member 4 releases the cooperation with the limit groove 14.

[0044] Specifically, the limiting member 4 can be continuously switched between a first angular phase and a second angular phase.

[0045] When the stopper 4 is in the first angular phase, the stopper 4 engages with the stopper slot 14, and the wiring box 2 cannot be withdrawn from the wiring box 1. When the stopper 4 is in the second angular phase, the stopper 4 and the stopper slot 14 are released, and the wiring box 2 can be withdrawn from the wiring box 1. The stopper 4 locks the position of the wiring box 2, preventing the wiring box 2 from being separated from the wiring box 1 without manual operation, thereby ensuring the stability of the optical fiber interface connection.

[0046] like Figure 6 As shown, the wiring box 2 is further provided with a second installation position 25 and a clamping portion 26 ; the limiting member 4 cooperates with the second installation position 25 and is clamped with the clamping portion 26 .

[0047] like Figure 12 and Figure 13 As shown, Figure 13 Is with Figure 12 From the same viewing angle, a partial enlarged view of portion F is shown when the stopper is in the second angular phase. Specifically, the wiring box 2 is further provided with a stopper opening corresponding to the stopper slot 14. When the stopper 4 rotates in the first direction and enters the stopper opening and the stopper slot 14, the stopper 4 is in the first angular phase. When the stopper 4 rotates in the second direction, the stopper 4 leaves the stopper opening and the stopper slot 14, and the stopper 4 is in the second angular phase.

[0048] The stopper 4 fits within the second mounting position 25, with one end of the stopper 4 extending beyond the wiring box 2, facilitating manual rotation. To enable the stopper 4 to rotate within the second mounting position 25, a clamping portion 26 is provided within the wiring box 2 to secure the end of the stopper 4 that does not extend beyond the wiring box 2, allowing for stable rotation of the stopper 4.

[0049] Refer again Figure 2 and Figure 3 The floating docking optical fiber adapter also includes a second connector 5, which is fixedly connected to the distribution box 1; the first connector 3 is plugged into one end of the second connector 5, and the other end of the second connector 5 is used to connect to an external optical fiber.

[0050] The second connector 5 is fixedly connected to the wiring box 1 so that the second connector 5 is located in a fixed position. When the wiring box 2 is pushed back into the wiring box 1, the first connector 3 can be plugged into the second connector 5 to achieve access to the optical fiber interface.

[0051] The bypass socket 6 is fixedly connected to the distribution box 1 , and the bypass socket 6 is communicatively connected to the second connector 5 .

[0052] The bypass socket 6 is communicatively connected to the second connector 5 via an optical fiber cable, and the bypass socket 6 is used to access an external optical fiber cable.

[0053] Reference Figure 4and Figure 9 There is a storage space in the distribution box 2, and at least one winding member 27 is provided in the storage space. The winding member 27 is used to wind the redundant optical fiber; at least one stop structure 271 is provided on the winding member 27 to prevent the redundant optical fiber from escaping from the storage space.

[0054] The winding member 27 and the stop structure 271 can realize the reasonable arrangement of redundant optical fibers, prevent the redundant optical fibers from being entangled, and facilitate manual operation.
