Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, specifically to an anti-misinsertion structure for optical fiber communication guide pins. Background Technology

[0002] Fiber optic communication is a communication technology that uses optical signals as the transmission carrier and optical fibers to transmit data. With its advantages of high speed, low loss, and resistance to electromagnetic interference, it has become the backbone of information transmission in core scenarios such as 5G base stations and data centers. During fiber optic connection, the guide pin is a critical component. It must be accurately inserted into the positioning hole of the fiber optic connector to ensure that the two fiber cores are aligned, preventing signal attenuation or interruption. However, in practice, the guide pin is prone to connection failure due to incorrect insertion, and may even scratch the fiber end face. Therefore, a dedicated guide pin anti-misinsertion structure must be used, with physical limits or markings to guide and ensure accurate alignment each time, maintaining the stability and reliability of fiber optic communication.

[0003] Chinese Utility Model Patent Publication No. CN209167592U discloses an MPO fiber optic connector. The specification includes a male plug, a female plug, and an adapter. The male and female plugs are mainly composed of a connecting shell, a collar, and optical fibers. A raised rib is formed on the outer surface of the connecting shell, and a groove is formed on the inner surface of the adapter's fitting hole. The raised rib and the groove are configured such that when the male and female plugs are fitted into the fitting hole of the adapter, they engage with each other to form a stable connection structure. In the male and female plugs, the optical fibers twisted in the collar separate into multiple fiber units, which extend to the front end of the collar to form contact ends. When the male and female plugs are stably connected by the adapter, the contact ends at both ends contact and connect with each other. However, during the connection process, the raised ribs of the male and female plugs may still be mistakenly inserted into each other's grooves, causing damage to the components due to forced mating. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-layer distributed flower bulb planting device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic communication guide pin anti-misinsertion structure, including an MPO adapter, and a left fiber optic bundle and a right fiber optic bundle located on its left and right sides.

[0008] Through the above technical solution, the number of male terminal one and female terminal one, as well as female terminal two and male terminal two, are all twenty times that of the MPO adapter, and they correspond one-to-one. The guide pin one and guide groove one are plug-in connected. The design of the vertical cross-section of the insertion end one having a semi-circular structure at both ends and the vertical cross-section of the insertion end two having a "︹" shaped structure, prevents mis-insertion when connecting the left and right fiber optic bundles to the MPO adapter. The design of the guide pin two and guide groove two for plug-in connection makes the plug-in connection of the left and right fiber optic bundles to the MPO adapter more accurate, and the plug-in connection operation is simple, improving work efficiency.

[0009] Preferably, the guide pin mounting assembly includes a pin seat, which is mounted on the protruding end of the left fiber optic bundle and the concave end of the MPO adapter facing the right fiber optic bundle. Guide pin one and guide pin two are welded and mounted on the outside of the pin seat. Guide groove one and guide groove two are respectively provided on the concave end of the MPO adapter facing the left fiber optic bundle and the protruding end of the right fiber optic bundle facing the MPO adapter.

[0010] Preferably, the vertical cross-sections of the first guide pin and the first guide groove are both n-shaped, and the vertical cross-sections of the second guide pin and the second guide groove are both ︹-shaped.

[0011] Through the above technical solution, the vertical cross-sections of both guide pin one and guide groove one are n-shaped, and the vertical cross-sections of both guide pin two and guide groove two are ︹-shaped. The two guide pins with different shapes achieve the function of preventing mis-insertion, preventing mis-insertion, and preventing damage to the components caused by forced docking.

[0012] Preferably, the hook assembly includes a hook body, and hook bodies are provided on the upper and lower parts of the left and right optical fiber bundles facing the MPO adapter. A torsion spring shaft is rotatably installed inside the hook body, and positioning blocks are provided at the connection between the left optical fiber bundle and the MPO adapter and at the connection between the right optical fiber bundle and the MPO adapter.

[0013] Through the above technical solution and the design of the hook assembly, quick assembly and disassembly between the left and right fiber optic bundles and the MPO adapter are achieved. The assembly and disassembly are simple, the press-type buckle can be operated with one hand, and the locking strength is high, preventing the left and right fiber optic bundles from loosening with the MPO adapter.

[0014] Preferably, the number of hook assemblies is four times that of the MPO adapter, and the two ends of the torsion spring shaft pass through the hook body and extend to one side of the groove.

[0015] The above technical solution, with a design where the number of hook components is four times that of the MPO adapter, distributes the force when the MPO adapter is connected to the left and right fiber optic bundles, preventing the equipment from deforming due to excessive force. The design where the torsion spring shaft passes through both ends of the hook body and extends to one side of the groove enhances the stability of the torsion spring shaft installation and increases the service life of the hook.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] like Figure 1-8 As shown, the present invention provides a fiber optic communication guide pin anti-misinsertion structure, including an MPO adapter 1, and a left fiber optic bundle 2 and a right fiber optic bundle 3 located on its left and right sides. A guide pin mounting assembly 4 is provided between the left fiber optic bundle 2 and the MPO adapter 1, and between the right fiber optic bundle 3 and the MPO adapter 1. A groove 6 is provided on the upper and lower surfaces of the left fiber optic bundle 2 and the right fiber optic bundle 3, and a groove 7 is provided on the upper and lower surfaces of the MPO adapter 1. A hook assembly 5 is provided between the left fiber optic bundle 2 and the MPO adapter 1, and between the right fiber optic bundle 3 and the upper surface of the MPO adapter 1. The left fiber optic bundle 2 includes an insertion end 201, which is fixedly installed at the end of the left fiber optic bundle 2 facing the MPO adapter 1. A male terminal 202 is fixedly installed on the side of the insertion end 201 facing the MPO adapter 1.

The inside of the MPO adapter 1 facing the left fiber optic bundle 2 has a female terminal 204 that is compatible with the male terminal 202. The right fiber optic cable bundle 3 includes an insertion end 301, which is fixedly installed at the end of the right fiber optic cable bundle 3 facing the MPO adapter 1. The side of the MPO adapter 1 facing the right fiber optic cable bundle 3 has a plug interface 303 that is compatible with the insertion end 301. The inside of the MPO adapter 1, on the side facing the right fiber optic cable bundle 3, has a male terminal 304 fixedly installed. The side of the insertion end 301 facing the MPO adapter 1 has a female terminal 302 that is compatible with the male terminal 304. Mis-insertion occurs when the MPO adapter 1 is connected. Example 2

[0021] like Figure 2-8 As shown, as an improvement to the previous embodiment, in order to prevent mis-insertion when the left fiber optic bundle 2 and the right fiber optic bundle 3 are connected to the MPO adapter 1.

[0022] Specifically, the guide pin mounting assembly 4 includes a pin seat 401, which is mounted on the protruding end of the left fiber optic bundle 2 and the concave end of the MPO adapter 1 facing the right fiber optic bundle 3. Guide pin 1 402 and guide pin 2 403 are welded and mounted on the outside of the pin seat 401. Guide groove 1 404 and guide groove 2 405 are respectively opened on the concave end of the MPO adapter 1 facing the left fiber optic bundle 2 and the protruding end of the right fiber optic bundle 3 facing the MPO adapter 1.

[0023] Specifically, the vertical cross-sections of guide pin 402 and guide groove 404 are both n-shaped, while the vertical cross-sections of guide pin 403 and guide groove 405 are both ︹-shaped. The advantage is that, by using n-shaped vertical cross-sections for guide pin 402 and guide groove 404, and ︹-shaped vertical cross-sections for guide pin 403 and guide groove 405, the two guide pins with different shapes prevent mis-insertion, thus preventing damage to the components from forced connection. Example 3

[0024] like Figure 2-8 As shown, as an improvement to the previous embodiment, in order to achieve quick assembly and disassembly of the left fiber optic bundle 2 and the right fiber optic bundle 3 with the MPO adapter 1.

[0025] Specifically, the number of male terminal 202 and female terminal 204, as well as female terminal 302 and male terminal 304, are all twenty times that of MPO adapter 1. The vertical cross-sections of the corresponding insertion end 201 and the interface 203 are semi-circular at both ends, while the vertical cross-sections of the insertion end 301 and the interface 303 are “︹” shaped.

[0026] Specifically, guide pin 402 and guide groove 404 are connected by a plug-in joint, as are guide pin 403 and guide groove 405. The advantages are that the number of male terminals 202 and female terminals 204, and the number of female terminals 302 and male terminals 304, are twenty times that of MPO adapter 1, and they correspond one-to-one. The plug-in connection between guide pin 402 and guide groove 404, along with the semi-circular structure at both ends of the vertical cross-section of insertion end 201 and the "︹"-shaped structure of the vertical cross-section of insertion end 301, prevents mis-insertion when connecting the left fiber optic bundle 2 and the right fiber optic bundle 3 to MPO adapter 1. The plug-in connection between guide pin 403 and guide groove 405 ensures more precise insertion of the left fiber optic bundle 2 and MPO adapter 1, and the right fiber optic bundle 3 and MPO adapter 1, while simplifying the connection operation and improving work efficiency.

[0027] Specifically, the hook assembly 5 includes a hook body 501. Hook bodies 501 are provided on the upper and lower parts of the left fiber optic bundle 2 and the right fiber optic bundle 3 facing the MPO adapter 1. A torsion spring shaft 502 is rotatably mounted inside the hook body 501. Positioning blocks 503 are provided at the connection points of the left fiber optic bundle 2 and the MPO adapter 1, and at the connection points of the right fiber optic bundle 3 facing the MPO adapter 1. The advantages are that the design of the hook assembly 5 enables quick assembly and disassembly between the left fiber optic bundle 2 and the right fiber optic bundle 3 and the MPO adapter 1, and the assembly and disassembly are simple. The press-type hooks can be operated with one hand, and the locking strength is high, preventing loosening between the left fiber optic bundle 2 and the right fiber optic bundle 3 and the MPO adapter 1.

[0028] Specifically, the number of hook assemblies 5 is four times that of MPO adapter 1, and the two ends of the torsion spring shaft 502 pass through the hook body 501 and extend to the side of the groove 6. The advantage is that by designing the number of hook assemblies 5 to be four times that of MPO adapter 1, the force is distributed when MPO adapter 1 is connected to the left fiber optic bundle 2 and the right fiber optic bundle 3, avoiding deformation of the equipment due to excessive force. Furthermore, the design of the torsion spring shaft 502 passing through the hook body 501 and extending to the side of the groove 6 enhances the stability of the torsion spring shaft 502 installation and increases the service life of the hook.

[0029] Working principle: In use, align the insertion end 201 of the left fiber optic cable bundle 2 with the insertion interface 203 for connection. Then, press the hook body 501 of the hook assembly 5 on the upper and lower parts of the left fiber optic cable bundle 2 facing the MPO adapter 1 to make the hook body 501 tilt up towards the MPO adapter 1. Then, guide the guide pins 402 and 403 to the guide grooves 404 and 405, and guide the male terminal 202 and female terminal 204 to align and guide them. Then, release the hook body 501 to reset it, completing the connection between the left fiber optic cable bundle 2 and the MPO adapter. First, connect the right fiber optic cable 3. Then, align the insertion end 301 of the right fiber optic cable 3 with the plug interface 303 and plug them in. Next, press the hook body 501 of the hook assembly 5 on the upper and lower parts of the right fiber optic cable 3 facing the MPO adapter 1 so that the hook body 501 is raised close to the MPO adapter 1. Then, guide the guide pin 402 and guide pin 403 with the guide groove 404 and guide groove 405, and guide the male terminal 304 and female terminal 302. Then, release the hook body 501 to reset it, thus completing the connection between the right fiber optic cable 3 and the MPO adapter 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
