Description

Technical Field

[0001] This utility model relates to the field of fiber optic terminal box technology, and more specifically, to the terminal fixing structure of a fiber optic terminal box. Background Technology

[0002] A fiber optic terminal box is the termination point of a fiber optic cable. One end is the fiber optic cable, and the other end is a pigtail. Essentially, it is a device that splits a fiber optic cable into individual optical fibers. A typical fiber optic terminal box consists of a housing, a fiber optic adapter board, fiber optic adapters, a pigtail manager, guide rails, and a support.

[0003] The fiber optic adapter is the connection port between the terminal box and external devices. Devices that need to connect to the terminal box insert the terminals on the connector into the fiber optic adapter to complete the connection. However, since the fiber optic adapter of the terminal box is exposed to the air, and the terminal box is also exposed to the air to meet its own heat dissipation requirements, the fiber optic adapter interface may become loose after prolonged connection or increased number of plugging and unplugging cycles. When the terminal box collides with other objects, the connector may fall off the adapter.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a terminal fixing structure for an optical fiber terminal box.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The terminal fixing structure of the fiber optic terminal box includes a box body and several adapters fixedly connected to one end of the box body. A box cover is detachably connected to the top surface of the box body. A receiving plate that abuts against the bottom surface of the adapter is fixedly connected to the side wall of the box body. A sealing plate is rotatably connected to the side of the receiving plate away from the box body. The sealing plate abuts against the end face of the adapter. A deformation piece one and a deformation piece two are fixedly connected to the side of the receiving plate and the sealing plate near the adapter, respectively. A connecting plate corresponding to the adapter is slidably connected to one side of the box cover. A deformation piece three is fixedly connected to the bottom surface of the connecting plate. The cross-sectional shape of the connecting plate, the receiving plate and the sealing plate are all arc-shaped.

[0007] The present invention is further configured such that: the opening directions of the receiving plate and the connecting plate are opposite to each other; the length of the adapter is less than the length of the receiving plate; the thickness of the first deformation piece is less than the thickness of the second deformation piece; and the thickness of the third deformation piece is greater than the thickness of the first deformation piece.

[0008] The present invention is further configured such that: a rotating hole is provided at the rotating connection between the receiving plate and the sealing plate, and a torsion member is fixedly connected in the rotating hole to keep the receiving plate and the sealing plate in a perpendicular state.

[0009] The present invention is further configured such that: a limiting plate one restricting its deformation direction is fixedly connected to one side of the first deformation plate, and a limiting plate two is fixedly connected to the side of the third deformation plate away from the limiting plate one.

[0010] The present invention is further configured such that: a receiving groove is provided on the side wall of the box cover, a plurality of connecting plates are slidably connected in the receiving groove, and a cover plate is fixedly connected to the end face of the plurality of connecting plates.

[0011] The present invention is further configured such that: a sliding groove is provided on the inner top surface of the receiving groove, and the inner top surface of the sliding groove and the top surface of the connecting plate are fixedly connected by a telescopic rod, and the telescopic rod is provided on the side of the connecting plate away from the opening of the receiving groove.

[0012] The present invention is further configured such that: a plurality of locking blocks are fixedly connected to the top surfaces of the sealing plate and the receiving plate respectively, and the bottom surface of the connecting plate is provided with a locking groove corresponding to the locking blocks.

[0013] In summary, this utility model has the following beneficial effects: Since the sealing plate, the receiving plate, and the connecting plate are all set on the box body, regardless of the type of connector they are compatible with, the first, second, and third deformation plates can change their own shape according to the outer peripheral wall of the connector and adapter after contacting them, thus ensuring the stable fixation of the connector and adapter of the first, second, and third deformation plates.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] The terminal fixing structure of the fiber optic terminal box, such as Figures 1-3As shown, the device includes a housing 1 and several adapters 2 fixedly connected to one end of the housing 1. A cover 3 is detachably connected to the top surface of the housing 1. A receiving plate 4, which abuts against the bottom surface of the adapter 2, is fixedly connected to the side wall of the cover 3. A sealing plate 5 is rotatably connected to the side of the receiving plate 4 away from the housing 1. A rotating hole is provided between the receiving plate 4 and the sealing plate 5. A torsion spring is fixedly connected in the rotating hole. The torsion spring allows the sealing plate 5 and the receiving plate 4 to be in a vertical state in the initial state. Since a deformation sheet 6 and a deformation sheet 7 are respectively bonded to the side of the receiving plate 4 and the sealing plate 5 near the adapter 2, when the sealing plate 5 and the adapter 2 are in a vertical state, the sealing plate 5 can be rotated vertically. When the end faces of adapter 2 are aligned, the second deformation piece 7 replaces the sealing plate 5 and abuts against the end face of adapter 2. This prevents external moisture or impurities from entering the interior of adapter 2, ensuring the stability and safety of adapter 2 during use. Before the worker inserts the connector into adapter 2, pressure is applied to the sealing plate 5 to rotate it downwards until it is on the same horizontal plane as the receiving plate 4. After the connector and adapter 2 are connected, the connector is parallel to the ground. Therefore, the connector abuts against the top surface of the second deformation piece 7, and the pressure applied by the connector to the sealing plate 5 is less than the elastic force of the torsion member. Therefore, the sealing plate 5 will not rotate upwards and squeeze the connector, ensuring a stable connection between the two.

[0020] A plurality of connecting plates 8, corresponding one-to-one with several adapters 2, are slidably connected to one end of the cover 3 near the adapter 2. A deformation sheet 9 is adhered to the bottom surface of the connecting plate 8. The openings of the connecting plate 8 and the receiving plate 4 are opposite to each other. Therefore, when the connecting plate 8 and the receiving plate 4 abut against each other, they can completely cover and fix the adapter 2 and the connector, preventing the connector from bending due to downward pressure caused by its large weight. Since the receiving plate 4, the sealing plate 5, and the connecting plate 8 are all fixedly connected to the box body 1 and the cover 3, and since the deformation sheet 6, the deformation sheet 7, and the deformation sheet 9 have elastic deformation properties, therefore… Regardless of the model and cross-sectional shape of the connector connected to adapter 2, the elastic deformation plates 6, 7, and 9 can deform under pressure and fit into adapter 2 and the connector. Utilizing the elastic deformation properties of these plates, when adapter 2 is impacted, the impact force is transmitted to them, and their own elastic deformation properties release this impact force, preventing it from acting directly on adapter 2 and the connector. This further prevents adapter 2 from detaching from the connector, ensuring stable signal transmission.

[0021] The length of adapter 2 is less than the length of receiving plate 4, thus providing space for sealing plate 5 to rotate upwards. The length of connecting plate 8 is equal to the sum of the lengths of sealing plate 5 and receiving plate 4, thereby achieving stable fixation of the connector and adapter 2. When the connector is not fixed, the thickness of deformation piece 1 6 is less than the thickness of deformation piece 2 7. At this time, deformation piece 1 6 abuts against the bottom surface of adapter 2. Since the size of the connector connected to adapter 2 is variable, increasing the thickness of deformation piece 2 7 ensures that when the cross-sectional area of ​​the connector is small, due to the larger thickness of deformation piece 2 7, it will still abut against the connector to achieve the functions of fixation and shock absorption. If the cross-sectional area of ​​the connector is large, the connector will apply pressure to deformation piece 2 7, causing it to deform. Since the deformation of deformation piece 2 7 is greater at this time, the static friction between the two will also increase, enabling... To better limit the deformation of the connector in different directions and ensure connection strength, the thickness of the third deformation piece 9 is greater than that of the first deformation piece 6. Therefore, when the receiving plate 4 abuts against the sealing plate 5 and the connecting plate 8, the third deformation piece 9 will inevitably undergo elastic deformation under the action of the connector and the adapter 2, thereby enhancing the fixing effect of the connecting plate 8, the receiving plate 4, and the sealing plate 5 on the connector and the adapter 2. The cross-sectional shape of the connecting plate 8, the receiving plate 4, and the sealing plate 5 are all arc-shaped. By setting the cross-sectional shape of the three, the deformation direction of the first deformation piece 6, the second deformation piece 7, and the third deformation piece 9 is limited, so that the first deformation piece 6, the second deformation piece 7, and the third deformation piece 9 can deform under pressure and abut against the side wall of the connector and the adapter 2 in the width direction, thereby ensuring the complete wrapping of the connector and the adapter 2 by the first deformation piece 6, the second deformation piece 7, and the third deformation piece 9.

[0022] A limiting piece 10 is fixedly connected to one side of deformable piece 6 to restrict its deformation direction. A limiting piece 2 11 is fixedly connected to the side of deformable piece 3 9 away from limiting piece 10. The hardness of limiting pieces 10 and 2 11 is greater than that of deformable pieces 6, 7, and 9. One end of limiting pieces 10 and 2 11 is fixedly connected to the end face of the box body 1 along its length. Because limiting pieces 10 and 2 11 have greater hardness and remain in their fixed positions, and because they are located on different sides with their bottom surfaces on the same horizontal plane, deformable pieces 6 and 3 9 cannot move closer to the limiting piece after being compressed. The direction of the first piece 10 and the second piece 11 can only move to the side away from the first piece 10 and the second piece 11, thus ensuring that the first piece 6 and the third piece 9 have sufficient area to contact the adapter 2. Several locking blocks 14 are fixedly connected to the top surfaces of the sealing plate 5 and the receiving plate 4 respectively. The bottom surface of the connecting plate 8 is provided with a slot corresponding to the locking block 14. The locking block 14 and the slot are used to achieve a stable connection between the receiving plate 4, the sealing plate 5 and the connecting plate 8. When the locking block 14 is engaged with the slot, the distance between the receiving plate 4, the sealing plate 5 and the connecting plate 8 is reduced. Therefore, the first piece 6, the second piece 7 and the third piece 9 will be subjected to pressure and undergo sufficient deformation to wrap the connector and the adapter 2.

[0023] A receiving groove 12 is provided on the side wall of the box cover 3. Several connecting plates 8 are slidably connected in the receiving groove 12. A cover plate 13 is fixedly connected to the end face of the connecting plates 8, which allows the connecting plates 8 to move together. A handle is fixedly connected to the side of the cover plate 13 away from the receiving groove 12 to increase the contact area between the hand and the box cover 3, making it easier for workers to pull out the box cover 3 using the handle. A sliding groove is provided on the inner top surface of the receiving groove 12. The inner top surface of the sliding groove and the top surface of the connecting plates 8 are fixedly connected by a telescopic rod. A sliding plate is slidably connected in the sliding groove. Several telescopic rods are fixedly connected to the sliding plate by bolts. Therefore, people can pull out all the connecting plates 8 by pulling the handle. The telescopic rod includes a long rod and a sliding rod slidably connected in the long rod. The sliding top surface and the inner top surface of the long rod are connected by a spring. When several connecting plates 8 are placed in the receiving groove 12, the sliding rod is located inside the long rod. At this time, the spring is in a contracted state. Since the telescopic rod is set on the side of the connecting plate 8 away from the groove opening of the receiving groove 12, when the telescopic rod is pulled out, it can ensure that the connecting plate 8 is completely removed from the receiving groove 12. When the telescopic rod is removed from the receiving groove 12, the pressure on the spring disappears and a pushing force is applied to the sliding rod, causing it to slide down along the inner wall of the long rod. The inner wall of the long rod will provide a limiting effect on the movement of the sliding rod, ensuring that the connecting plate 8 can move vertically downward under the action of the sliding rod. Then, the worker presses the locking block 14 into the locking groove to achieve stable fixation of the sealing plate 5, the connecting plate 8 and the receiving plate 4.

[0024] Working principle: In the initial state, the connecting plate 8 is housed in the receiving groove 12, the receiving plate 4 abuts against the adapter 2 through the deformation piece 6, the sealing plate 5 is set perpendicular to the receiving plate 4 and the deformation piece 7 abuts against the end face of the adapter 2, thereby ensuring the seal of the adapter 2 port. When it is necessary to connect the connector to the adapter 2, the worker first applies pressure to the sealing plate 5 to move it closer to the ground, making it easier for the worker to insert the connector into the port of the adapter 2. At this time, the connector applies pressure to the sealing plate 5, thereby preventing the sealing plate 5 from rotating under the action of the torsion member. After the box cover 3 is placed on the box body 1, the worker pulls the handle to pull several connecting plates 8 out of the receiving groove 12. When the telescopic rod is fully inserted into the receiving groove 12, the length of the telescopic rod increases, thereby aligning the connecting plate 8 with the receiving plate 4. The worker then presses the connecting plate 8 and the receiving plate 4 to achieve the engagement of the locking block 14 with the locking groove, thereby achieving stable fixation of the connecting plate 8 and the receiving plate 4.
