Abstract
Description
Technical Field
[0001] This utility model relates to a tail tagging device, and more particularly to an optical fiber tail tagging card and a tag card. Background Technology
[0002] The development of broadband technology has brought tremendous changes to people's work and life. The transmission of broadband signals requires the help of optical fibers. However, optical fibers cannot be connected end-to-end in one piece. Multiple optical fiber segments need to be spliced in the middle. In places such as base stations, optical distribution boxes, and core equipment rooms, a large number of pigtails and ports need to be connected.
[0003] Different optical fibers differ in the services they carry, the source ports and destination ports used for transmission, and therefore require separate labeling. The traditional labeling method involves attaching paper tags to the fiber optic pigtails, which are then manually inventoried one by one during resource checks. This method is clearly insufficient in terms of efficiency and accuracy, and cannot meet the management needs of massive optical resources.
[0004] Leveraging the passive, high-penetration, low-cost, and rewritable characteristics of radio frequency (RF) sensing technologies, RFID tags are increasingly widely used for optical resource management. By writing port information into corresponding tags, efficient and accurate inventory management of port resources can be achieved using appropriate readers. However, how to connect the tags to fiber optic pigtails is a problem that needs to be solved. One option is to modify the fiber optic connectors, integrating the tags during connector manufacturing. However, this approach requires modifications to the connector production equipment, increasing costs for manufacturers. Furthermore, if existing optical resources need to be modified, all fiber optic connectors would need to be replaced, resulting in an excessive workload and cost.
[0005] Therefore, there is an urgent need for a facility that can directly connect inductive tags to existing fiber optic connectors. Utility Model Content
[0006] The purpose of this invention is to provide an optical fiber tail tag and tag card to reliably connect the inductive tag to a common optical fiber connector, in order to address the problems mentioned above.
[0007] The technical solution adopted in this utility model is as follows:
[0008] An optical fiber tail tag, characterized in that it includes an optical fiber tail tag body and a tag fixing component;

[0010] The label fixing member is provided with a label mounting portion for mounting the sensing label.
[0011] To solve the above problems, the application further provides a label card, which comprises the optical fiber tail tag card and a sensing label mounted on the sensing mounting portion of the label fixing member.
[0012] In conclusion, due to the adoption of the above technical solutions, the application has the following beneficial effects:
[0013] The optical fiber tail tag card is designed to adapt the shape of the first cavity to the shape of the optical fiber joint, and when connected, the optical fiber joint is inserted through the first cavity, so that the optical fiber tail tag card and the optical fiber joint are quickly and reliably connected.

DETAILED DESCRIPTION
[0020] The application will be described in detail below with reference to the accompanying drawings.
[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will make further detailed description to the utility model by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.
[0022] For the convenience of description, in the present application, the end of the fiber joint close to the port is called front end, the other end opposite to it is called end, and the part between the two ends is called middle section.
[0023] The embodiment of the present application provides a kind of fiber tail sign card, as shown in Figure 1 It includes fiber tail sign card main body 1 and label fixing piece 2 two parts. Wherein, fiber tail sign card main body 1 is responsible for being connected with fiber joint, and label fixing piece 2 is responsible for being connected with inductive label (such as radio frequency label, electromagnetic label etc.).
[0024] First cavity 11 is opened on fiber tail sign card main body 1 and first cabin body 12. First cabin body 12 is used to accommodate label fixing piece 2;The shape of first cavity 11 is adapted to the shape of at least one fiber joint. Label fixing piece 2 is provided with label mounting portion 21 for installing inductive label.
[0025] Between first cabin body 12 and label fixing piece 2, in some embodiments, drawer type connecting structure can be used to facilitate the removal or assembly of label fixing piece 2.
[0026] In use, label fixing piece 2 is assembled into first cabin body 12 of fiber tail sign card main body 1, and fiber joint is assembled into first cavity 11 of fiber tail sign card main body 1, that is, assembly is completed. If inductive label is installed to label mounting portion 21 of label fixing piece 2 at this time, the installation and fixation of inductive label are realized.
[0027] In some embodiments, longitudinal slit 13 is opened on the side wall of first cavity 11. Generally, fiber joint is connected with optical fiber, and for fiber jumper, generally both ends are connected with fiber joint, so that the optical fiber cannot pass through the first cavity 11 of the fiber tail sign card main body 1. For this purpose, longitudinal slit 13 is opened on the side wall of first cavity 11, so that the fiber tail does not need to be inserted into the first cavity 11 as a whole to connect the fiber tail sign card, and only needs to be inserted into the first cavity 11 of the fiber tail sign card main body 1 along the longitudinal slit 13, and then the fiber tail sign card is moved towards the front end of the fiber joint so that the fiber joint is inserted into the first cavity 11.
[0028] In order to improve the versatility of the fiber tail card, in some embodiments, the shape of the first cavity 11 of the fiber tail card body 1 is designed to be adapted to the shape of the FC type fiber joint and the SC type fiber joint. The FC type fiber joint is a circular joint, and the SC type fiber joint is a square joint, that is, the fiber tail card of the present application is adapted to circular and square fiber joints. The common fiber joint type is also ST type, which is similar in structure to the FC type fiber joint, so it can also be adapted to a certain extent.
[0029] As shown in Figure 2 , the FC type fiber joint is generally a cylindrical structure, so the inner wall of the first cavity 11 at least surrounds a cylindrical inner cavity. The cylindrical structure is easy to rotate circumferentially, so in order to improve the stability of the connection, the first cavity 11 inner wall is provided with a first limiting structure 14 to prevent the FC type fiber joint from rotating circumferentially.
[0030] As a feasible implementation, the first limiting structure 14 is a tooth type structure that matches the tooth-like stripes on the outer wall of the FC type fiber joint to limit the circumferential rotation of the FC type fiber joint. In specific implementation, the tooth type structure can be provided only on part of the inner wall of the first cavity 11, for example, on the left and right opposite inner walls of the first cavity 11, and other areas can not be provided.
[0031] In addition, in order to prevent the fiber tail card from being separated from the FC type fiber joint, a second limiting structure 15 is provided on the inner wall of the first cavity 11 to prevent the FC type fiber joint from moving axially.
[0032] Generally, the fiber tail card is installed when the fiber has already been connected to the port, at which time the front end of the fiber joint is the flange plate of the port. In order to prevent the fiber tail card from colliding with the flange plate of the port when moving, the second limiting structure 15 is arranged at one end of the first cavity 11 close to the end of the fiber joint, so that when the fiber tail card is moved to a certain extent, the second limiting structure 15 will limit the fiber tail card from continuing to move towards the port.
[0033] As a feasible implementation, the second limiting structure 15 adopts a limiting step surface structure, and on the side of the limiting step surface close to the port, the fiber joint can move in the first wall, and on the side of the limiting step surface away from the port, the fiber joint cannot pass through. As shown in Figure 3 , it is a state diagram of the fiber tail card connecting the FC type fiber joint.
[0034] As shown in Figure 4 , the SC type fiber joint is generally a square structure, so the inner wall of the first cavity 11 simultaneously surrounds a square inner cavity. The shape of the first cavity 11 is the shape formed by coaxially combining a cylindrical and a square cylindrical body. For the SC type fiber joint, the square structure naturally realizes the circumferential limiting.
[0035] In some embodiments, the opposite sides (e.g. left and right sides) of the inner wall of the middle section of the first cavity 11 are provided with first clamping holes 16 for clamping the middle section 32 of the SC fiber connector.
[0036] As a feasible implementation, the first clamping hole 16 can be designed as a protruding structure on the inner wall of the first cavity 11, clamping the middle section 32 of the SC fiber connector from two opposite surfaces of the SC fiber connector to prevent falling off. The protrusion can be designed as a trapezoidal clamping point. In addition, the first clamping hole 16 does not interfere with the movable area of the FC fiber connector.
[0037] In addition, if the first clamping hole 16 and the first limiting structure 14 in the previous embodiment are arranged on the same side of the inner wall of the first cavity 11, the first limiting structure 14 and the first clamping hole 16 need to be arranged at different positions.
[0038] In other embodiments, the opposite sides of the inner wall of the end of the first cavity 11 close to the end 33 of the SC fiber connector are provided with second clamping holes 17 for clamping the end 33 of the SC fiber connector to lock the end 33 of the SC fiber connector.
[0039] As a feasible implementation, the second clamping hole 17 can be a protruding structure on the inner wall of the first cavity 11, clamping the end 33 of the SC fiber connector from two opposite surfaces of the end 33 of the SC fiber connector. The protrusion can also be designed as a trapezoidal clamping point. When implemented simultaneously with the previous embodiments of designing the second limiting structure 15, the second clamping hole 17 can be designed on the surface away from the port side of the limiting step surface.
[0040] For the front end 31 of the SC fiber connector, as for the front end of the FC fiber connector, axial limiting is not required.
[0041] In use, the SC fiber connector is inserted into the first cavity 11, as shown in Figure 5 .
[0042] The embodiments of the present application also provide a label card, which comprises the fiber tail tag card of the above-mentioned embodiments, and a sensing label, such as a radio frequency label or other sensing label, is mounted on the sensing mounting portion of the label fixing member 2 of the fiber tail tag card.
[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
