Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector technology, and in particular to a compact 45° FA-MT fiber optic connector. Background Technology

[0002] According to Chinese Publication No. CN115267977B, an optical fiber coupler and an optical fiber plug are disclosed. The optical fiber coupler and plug of this invention address the issue that optical fibers, during use, can bend under various external forces. Excessive bending of the optical fiber can affect its functionality, especially when the fiber plug is manually inserted into the coupler. The optical fiber coupler includes an optical fiber protective sleeve. Through the cooperation of a cable tray and a sliding plate, the fiber plug is inserted into the coupler without direct manual insertion, reducing the external force on the optical fiber and decreasing its bending. The optical fiber plug is equipped with a protective sleeve and a fiber plug cover to protect the plug. The use of an elastic membrane, locking blocks, and locking slots prevents the fiber plug from easily falling out after insertion, thus stabilizing the use of the optical fiber coupler.

[0003] The aforementioned patent documents and prior art have the following technical problems:

[0004] 1. The fiber optic access direction adopts a straight-line access, which is not adaptable when multiple output or input ports are connected. In addition, the existing multi-interface has the problems of large space occupation and insufficient integration tightness.

[0005] 2. When using fiber optic access, the input and output ends are generally fixed, which is inconvenient to disassemble and replace, and is not conducive to daily maintenance and repair. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing multi-port multi-sided connectors, such as insufficient tightness, space occupation, and difficulty in disassembly and maintenance due to the fixed ends of the multi-sided connectors. Therefore, a compact 45° FA-MT multi-sided connector is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a compact 45° FA-MT fiber optic connector, comprising a multi-sided connector and a fiber optic body. The multi-sided connector has a port connection block and multiple port connection slots on its side, and the port connection block and port connection slots are located on different sides. An input socket and an output socket are snapped onto the surface of the multi-sided connector. The end of the input socket is provided with an input connection slot, and the end of the output socket is provided with an output connection block. Both the ends of the input socket and the output socket are connected to fiber optic ports, and the surface of the fiber optic ports is connected to the fiber optic body.

[0008] Preferably, the input socket has an input port at the end away from the input connection slot, the input port engages with the fiber optic port surface, and the input socket has an input transmission board inside, which is connected to the input connection slot and the fiber optic port via optical signals.

[0009] Preferably, the output base has an output port at the end away from the output connector block, the output port engages with the fiber optic port surface, and the output base has an output transmission board inside, the output transmission board is connected to the output connector block and the fiber optic port via optical signals.

[0010] Preferably, the sides of the input and output sockets that abut against the multi-sided connector are both 45-degree bevels, and the sides of the input socket that abut against the multi-sided connector are the same size.

[0011] Preferably, the multi-sided connector has a control motherboard inside, and the surface of the control motherboard is respectively connected with a port connection block and a port connection slot.

[0012] Preferably, the surface of the optical fiber port is provided with a limiting plate, and the top surfaces of the input and output seats are provided with limiting grooves. The surface of the limiting plate engages with the surface of the limiting groove through protrusions.

[0013] Preferably, the input socket and the output socket are the same size, and the edges of the input socket, the output socket and the polygonal connector are all rounded.

[0014] Beneficial effects

[0015] In this invention, a multi-sided connector is used with a port connection block and multiple connection slots on the side for input and output sockets. This allows for surface connection of one input socket and multiple output sockets, which work in conjunction with the optical fiber body for signal transmission. The output sockets can be selected and installed in the corresponding positions according to the output direction requirements. Compared with the traditional multi-interface structure, the multi-sided connector can achieve access in different directions. At the same time, when multiple output sockets are connected, due to the influence of the 45-degree slope, the entire device after connection is a regular shape, which has high space utilization, reduces space occupation, and increases connection density.

[0016] In this invention, a modular design is adopted between the multi-sided connector and the input and output sockets. Both the input and output sockets are equipped with fiber optic ports and are tightly connected to the fiber optic body, ensuring the stability and reliability of signal transmission. In addition, the limiting plate on the surface of the fiber optic port engages with the limiting groove on the input and output sockets, further enhancing the stability of the connection and preventing loosening or detachment due to vibration or external force. This makes the connection and disassembly of each component relatively simple, facilitating daily maintenance and management by the user. Attached Figure Description

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0027] Reference Figure 1-5A compact 45° FA-MT fiber optic connector includes a multi-sided connector 1 and an optical fiber body 5. The multi-sided connector 1 has a port connection block 3 and multiple port connection slots 4 on its side, with the port connection block 3 and port connection slots 4 located on different sides. The multi-sided connector 1 contains a control main board 2, with the port connection block 3 and port connection slots 4 connected to its surface. The multi-sided connector 1, acting as the main body, combines with the optical fiber body 5 to transmit optical signals. The port connection block 3 and port connection slots 4 on the side provide connection interfaces with other fiber optic devices or systems. The multi-sided connector 1 is inserted and connected to output sockets 10 and input sockets 6 through the port connection slots 4 and port connection blocks 3. Simultaneously, the multi-sided connector 1 can directly connect to external fiber optic devices through the port connection slots 4 and port connection blocks 3. The design of the multi-sided connector 1 allows for connection from multiple directions, improving flexibility. The standardized design of the port connection blocks 3 and port connection slots 4 ensures compatibility with other devices.

[0028] To facilitate the connection of the fiber optic port 16 and the fiber optic body 5, an input socket 6 and an output socket 10 are provided on the surface of the multi-sided connector 1. The input socket 6 has an input connection slot 9 at its end, and the output socket 10 has an output connection block 13 at its end. Both the input socket 6 and the output socket 10 are connected to the fiber optic port 16, and the fiber optic body 5 is connected to the surface of the fiber optic port 16. The input socket 6 and the output socket 10 are respectively provided with the input connection slot 9 and the output connection block 13 for connecting to the fiber optic or fiber optic equipment. The fiber optic port 16 connects to the fiber optic body 5 to realize the input and output of optical signals. Since the sides of the input socket 6 and the output socket 10 that abut against the multi-sided connector 1 are both 45-degree bevels, and the sizes of the abutting surfaces of the input socket 6 and the multi-sided connector 1 are the same, when connecting, the input socket 6 and the output socket 10 are respectively installed in the corresponding positions of the multi-sided connector 1 to ensure that the 45° bevels are correctly aligned. The 45° bevel design optimizes the fiber optic connection angle and reduces the loss of optical signals. The locking mechanism ensures a stable connection of the fiber optic port 16.

[0029] To ensure stable access to fiber optic port 16, an input port 7 is provided at the end of the input socket 6 furthest from the input connection slot 9. The input port 7 engages with the surface of the fiber optic port 16. An input transmission board 8 is located inside the input socket 6, and the input transmission board 8 is connected to both the input connection slot 9 and the fiber optic port 16 via optical signals. An output port 11 is provided at the end of the output socket 10 furthest from the output connection block 13, and the output port 11 engages with the surface of the fiber optic port 16. An output transmission board 12 is located inside the output socket 10, and the output transmission board 12 is connected to both the output connection block 13 and the fiber optic port 16 via optical signals. The input transmission board 8 and the output transmission board 12 are responsible for transmitting optical signals from the input connection slot 9 to the fiber optic port 16 and from the fiber optic port 16 to the output connection block 13, respectively. The transmission boards are integrated inside the input socket 6 and the output socket 10 and are directly connected to the fiber optic port 16 and the connection slot. The optical signal connection technology ensures the efficiency and integrity of the optical signal during transmission. The design of the transmission board may involve precision components such as optical lenses and fiber arrays. Through the access of the input transmission board 8 and the output transmission board 12, the attenuation and distortion of the optical signal are reduced, and the overall performance of the multi-sided connector 1 is improved.

[0030] To ensure the stability of the fiber optic port 16, a limiting plate 15 is provided on the surface of the fiber optic port 16. Limiting grooves 14 are provided on the top surfaces of the input socket 6 and the output socket 10. The surface of the limiting plate 15 engages with the surface of the limiting groove 14 through protrusions, and the limiting plate 15 is fixed to the surface of the fiber optic port 16. The limiting grooves 14 are provided on the top surfaces of the input socket 6 and the output socket 10. During installation, the protrusions on the limiting plate 15 engage with the limiting grooves 14. The precise mechanical structure design ensures the accuracy and stability of the engagement, preventing the fiber optic port 16 from loosening or falling off under vibration or external force, and improving the reliability and durability of the multi-sided connector 1. The input socket 6 and the output socket 10 are the same size, and the edges of the surfaces of the input socket 6, the output socket 10, and the multi-sided connector 1 are all rounded. Specific Implementation Example 2:

[0032] Reference Figure 1-5 The multi-sided connector 1 is managed and controlled by the control motherboard 2, which is responsible for the communication between the port connection block 3 and the port connection slot 4. It is used to monitor the optical signal status or provide additional management functions. It has an internal photoelectric conversion module for accessing and transmitting optical fiber signals. The specific internal electrical components are set according to the actual use and the existing technology.

[0033] In summary:

[0034] 1. A multi-sided connector 1 is used with a port connection block 3 on the side and multiple connection slots for the input socket 6 and output socket 10 to be connected. This allows for surface connection of one input socket 6 and multiple output sockets 10. It works in conjunction with the optical fiber body 5 for signal transmission. The output socket 10 can be installed in the corresponding position according to the output direction requirements. Compared with the traditional multi-interface structure, the multi-sided connector 1 can realize access in different directions. At the same time, when multiple output sockets 10 are connected, due to the influence of the 45-degree slope, the entire device after connection is a regular shape, which has high space utilization, reduces space occupation, and increases connection density.

[0035] 2. A modular design is adopted between the multi-sided connector 1 and the input socket 6 and output socket 10. Both the input socket 6 and the output socket 10 are equipped with fiber optic ports 16, which are tightly connected to the fiber optic body 5, ensuring the stability and reliability of signal transmission. In addition, the limiting plate 15 on the surface of the fiber optic port 16 is designed to engage with the limiting groove 14 on the input socket 6 and the output socket 10, further enhancing the stability of the connection and preventing loosening or falling off due to vibration or external force. This makes the connection and disassembly between the various components relatively simple, facilitating daily maintenance and management by users.
