[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] like Figures 1 to 3 As shown, the optical fiber splicing and distribution device of this embodiment includes a splicing reel cover 500, a data acquisition board 200, multiple end identification cards 300, and multiple jumper identification connection structures 100 corresponding to each end identification card 300. The data acquisition board 200 integrates multiple card reader ports 201 adapted to each end identification card 300. The data acquisition board 200 is detachably installed on the inner outer end of the splicing reel cover 500. Each end identification card 300 is plugged into each card reader port 201 respectively. Each jumper identification connection structure 100 is connected to each end identification card 300 respectively, and each jumper identification connection structure 100 is used to connect to the jumper 400 corresponding to each end identification card 300.

[0024] like Figure 4As shown, the optical fiber splicing and distribution device of this embodiment is installed on the splicing tray 600. Since the splicing tray 600 is provided with a jumper mounting port 700 that is compatible with the jumper 400, each jumper 400 is plugged into the corresponding jumper mounting port 700. Therefore, the installation can be carried out without removing the jumper.

[0025] The optical fiber splicing and distribution device of this invention can collect data from the card reader on the data acquisition board 200 through the data acquisition device, and then obtain the data of each card reader port 201 and the data of the corresponding terminal identification card 300.

[0026] Therefore, the optical fiber splicing and distribution device according to the present invention can perform visual and digital transformation of the optical fiber network without removing the jumpers, without interrupting existing services, and can identify each interface of the jumpers. It can be adapted to all jumpers on the market, without the need for special customization based on the jumper heads, thus reducing the transformation cost of the optical fiber network. Moreover, the transformation process does not damage the jumpers, and the transformation process is simple and efficient.

[0027] like Figure 5 As shown, the fusion splice tray cover 500 includes a cover body and a data acquisition board mounting portion 501 disposed at the outer end of the cover body. Two snap-fit ​​protrusions 502 and two auxiliary positioning posts 503 are respectively provided on the inner wall of the data acquisition board mounting portion 501 to facilitate installation and positioning with the data acquisition board 200. Mounting positions 504 adapted to each card reader port 201 are also provided on the inner wall of the data acquisition board mounting portion 501, so that after the data acquisition board 200 is installed with the fusion splice tray cover 500, each card reader port 201 can be located at the edge of the data acquisition board mounting portion 501, facilitating subsequent insertion of the terminal identification card 300. Furthermore, a separator 505 is provided between two adjacent mounting positions 504 to facilitate quick and accurate location of the installation position when inserting the terminal identification card 300.

[0028] Specifically, such as Figure 6 This is a schematic diagram of the data acquisition board 200. Multiple card reader ports 201 on the data acquisition board 200 are sequentially arranged along its length. The data acquisition board 200 integrates a card reader circuit, which, since it uses existing technology, will not be described in detail here.

[0029] The data acquisition board 200 has two data interfaces 202 located near one end for connecting data acquisition devices and for connecting multiple data acquisition boards 200. When multiple fiber optic trolleys 600 are stacked sequentially, the upper and lower fiber optic trolleys 600 are connected via a data cable 800, such as... Figure 7 As shown.

[0030] The data acquisition board 200 is provided with snap-fit ​​holes 203 that match the snap-fit ​​protrusions 502, and auxiliary positioning holes 204 that match the auxiliary positioning posts 503. When the data acquisition board 200 is installed with the fiber optic tumbler cover 500, the auxiliary positioning posts 503 pass through the auxiliary positioning holes 204 respectively, and the snap-fit ​​protrusions 502 are engaged in the snap-fit ​​holes 203 respectively, thereby realizing the installation and positioning between the data acquisition board 200 and the fiber optic tumbler cover 500. Figure 3 As shown.

[0031] It should be noted that the number of buckle protrusions 502 and auxiliary positioning pins 503 can be set according to the actual situation. For example, two, three or more can be set. Correspondingly, two, three or more buckle holes 203 and auxiliary positioning holes 204 can also be set.

[0032] In addition to the aforementioned snap-fit ​​connection and auxiliary positioning method, the data acquisition board 200 and the fiber fusion tray cover plate 500 can also be connected detachably using screws, bolts, or other detachable connectors, as long as it is convenient to achieve a detachable connection between the data acquisition board 200 and the fiber fusion tray cover plate 500.

[0033] like Figure 8 As shown, the terminal identification card 300 integrates a terminal identification card circuit 301, which includes a circuit chip U1, a capacitor C1, and connecting lines. One end of the terminal identification card 300 is a plug-in terminal 302 adapted to the card reader port 201, and the other end of the terminal identification card 300 is provided with a connecting ring 303.

[0034] Specifically, the fiber optic cable splicing and distribution device of this embodiment of the invention has three structural forms of the jumper identification connection structure 100, which will be described in detail below.

[0035] like Figure 9 As shown, the first type of jumper identification connection structure of the present invention includes a connection body 1, a first snap connector 2 disposed at the first end of the connection body 1, and a wraparound snap fastener 3 disposed at the second end of the connection body 1. The wraparound snap fastener 3 includes a wraparound strap 31, a second snap connector 32, and a snap-fit ​​ring 33 that cooperates with the second snap connector 32. The second snap connector 32 is disposed at the second end of the connection body 1. One end of the wraparound strap 31 is connected to the second snap connector 32, and the other end of the wraparound strap 31 is connected to the snap-fit ​​ring 33. The second snap connector 32 can snap into the snap-fit ​​ring 33.

[0036] In use, the first connector 2 is snapped onto the connecting ring 303 of the end identification card 300, and then the second connector 32 is snapped onto the snapping ring 33 to form a loop, and the loop is wrapped around the jumper 6, thereby achieving a reliable connection between the corresponding jumper 6 and the end identification card 4.

[0037] The first connector 2 includes a first connector 21 and a first buckle 22 disposed on the first connector 21. The first connector 21 is fixed on the connecting body 1. Since the first buckle 22 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the first buckle 22 is set as a cone and has a locking protrusion. Therefore, the first buckle 22 can be smoothly locked into the ring of the end mark card 4 and limited by the locking protrusions on both sides.

[0038] The second snap-fit ​​connector 32 includes a second connector 321 and a second snap-fit ​​322 disposed on the second connector 321. The second connector 321 is fixed on the connecting body 1. Since the second snap-fit ​​322 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the second snap-fit ​​322 is set as a cone and has a snap-fit ​​protrusion. Therefore, the second snap-fit ​​322 can be smoothly snapped into the snap-fit ​​ring 33 and limited by the snap-fit ​​protrusions on both sides.

[0039] like Figure 10 As shown, the second type of jumper identification connection structure of the present invention includes a connection body 1, a first snap connector 2 disposed at the first end of the connection body 1, and a wraparound snap fastener 3 disposed at the second end of the connection body 1. The wraparound snap fastener 3 includes a wraparound strap 31, a second snap connector 32, and a snap-fit ​​ring 33 that cooperates with the second snap connector 32. The snap-fit ​​ring 33 is disposed at the second end of the connection body 1. One end of the wraparound strap 31 is connected to the snap-fit ​​ring 33, and the other end of the wraparound strap 31 is connected to the second snap connector 32. The second snap connector 32 can snap into the snap-fit ​​ring 33.

[0040] In use, the first connector 2 is snapped onto the connecting ring 303 of the end identification card 300, and then the second connector 32 is snapped onto the snapping ring 33 to form a loop, and the loop is wrapped around the jumper 6, thereby achieving a reliable connection between the corresponding jumper 6 and the end identification card 4.

[0041] The first connector 2 includes a first connector 21 and a first buckle 22 disposed on the first connector 21. The first connector 21 is fixed on the connecting body 1. Since the first buckle 22 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the first buckle 22 is set as a cone and has a locking protrusion. Therefore, the first buckle 22 can be smoothly locked into the ring of the end mark card 4 and limited by the locking protrusions on both sides.

[0042] The second snap-fit ​​connector 32 includes a second connector 321 and a second snap-fit ​​322 disposed on the second connector 321. The second connector 321 is fixed on the connecting body 1. Since the second snap-fit ​​322 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the second snap-fit ​​322 is set as a cone and has a snap-fit ​​protrusion. Therefore, the second snap-fit ​​322 can be smoothly snapped into the snap-fit ​​ring 33 and limited by the snap-fit ​​protrusions on both sides.

[0043] like Figure 11 As shown, the third type of jumper identification connection structure of the present invention includes a connection body 1, a first snap connector 2 disposed at the first end of the connection body 1, and a wraparound snap fastener 3 disposed at the second end of the connection body 1. The wraparound snap fastener 3 includes a wraparound belt body 31 and a second snap connector 32 connected to one end of the wraparound belt body 31. The wraparound belt body 31 includes a plurality of snap-fit ​​rings connected in sequence. The second snap connector 32 is disposed at the second end of the connection body 1 and can snap with the snap-fit ​​rings on the wraparound belt body 31.

[0044] In use, the first connector 2 is snapped onto the connecting ring 303 of the end identification card 300, and then the second connector 32 is snapped onto the snapping ring on the wrapping belt 31 to form a loop, and the loop is wrapped around the jumper 6, thereby achieving a reliable connection between the corresponding jumper 6 and the end identification card 4.

[0045] Since the wrapping belt 31 has multiple snap-fit ​​rings, the second snap-fit ​​connector 32 can be selected to snap-fit ​​with snap-fit ​​rings at different positions according to actual usage requirements, thereby adjusting the size of the ring and making it more adaptable.

[0046] The first connector 2 includes a first connector 21 and a first buckle 22 disposed on the first connector 21. The first connector 21 is fixed on the connecting body 1. Since the first buckle 22 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the first buckle 22 is set as a cone and has a locking protrusion. Therefore, the first buckle 22 can be smoothly locked into the ring of the end mark card and limited by the locking protrusions on both sides.

[0047] The second snap-fit ​​connector 32 includes a second connector 321 and a second snap-fit ​​322 disposed on the second connector 321. The second connector 321 is fixed on the connecting body 1. Since the second snap-fit ​​322 has a gap in the middle, the size of the gap can be adjusted by squeezing. The outer side of the second snap-fit ​​322 is set as a cone and has a snap-fit ​​protrusion. Therefore, the second snap-fit ​​322 can be smoothly snapped into the corresponding snap-fit ​​ring and limited by the snap-fit ​​protrusions on both sides.

[0048] Traditional fiber optic cable ties are susceptible to temperature changes and physical vibrations in various application scenarios, leading to variations in their tightening force. This can result in unstable fiber optic patch cord fixation, and overly tight binding can negatively impact fiber transmission quality, causing communication degradation or interruption. The patch cord identification connection structure described in this embodiment effectively solves this problem. The wraparound buckle 3 forms a loop during use; by fitting this loop onto the patch cord 6, a reliable connection between the patch cord 6 and the corresponding identification card 4 is achieved without damaging the patch cord 6, thus ensuring the quality of fiber optic transmission.

[0049] Specifically, the three types of jumper identification connection structures described in this embodiment of the invention can be injection molded from PE material, which has good ductility and a long service life. The length of the digital tag jumper identification connection structure can be set to about 15mm, which can be used for all jumpers on the market. No fiber removal modification is required during use, and existing services are not interrupted. The fiber optic network can be modified without interruption. It is convenient to use, does not damage the jumpers, and can be adapted to all jumpers on the market. It does not require special customization based on the jumper head, thereby effectively reducing the cost of fiber optic network modification.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
