Description

Technical Field

It has the function of connecting optical fibers with optical fibers, optical fibers with active devices, optical fibers with other passive devices, and optical fibers with instruments. The optical module is a very important optical signal interface device in optical fiber communication. It has an optical interface and an electrical interface. The optical interface connects to the optical fiber to transmit optical signals, and the electrical interface connects to external communication terminal equipment. The optical communication equipment is used to convert the two connectors.

[0004] In related technologies, equipment such as 5G base stations contains a large number of plug-in optoelectronic circuits. Because optoelectronic components are separated, there are numerous connectors, categorized into optoelectronic and non-optoelectronic types, requiring correct pairing of each. This makes installation and maintenance cumbersome and prone to errors. While integrating optoelectronic components into a small structure is relatively easy for multi-port connectors (due to their larger size), single-port connectors require smaller designs and must accommodate the differences in optoelectronic transmission, resulting in generally poorer structural manufacturability.

[0016] Furthermore, an axially extending capacitive groove is formed on the outer wall of the second base, and the capacitive groove communicates with the second opening; the optoelectronic connector includes a wire terminal, and the end of the capacitive groove away from the first base has a large-size section, and the cable is connected to the second end of the power transmission structure within the large-size section through the wire terminal.

[0017] Furthermore, the second seat includes a connecting seat and at least two cantilever arms disposed opposite each other.

[0046] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of this application and should not be regarded as undue limitations on this application.

[0047] In the description of the embodiments in this application, the orientations or positional relationships of "up", "down", "left", "right", "front", and "rear" are based on the appendix. Figure 1 The orientations or positional relationships shown are intended only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] like Figures 1 to 23 As shown, an optoelectronic connector includes: a housing assembly 1, a conductive component 3 for transmitting electricity, and a light guide component 2 for transmitting optical signals.

[0049] The housing assembly 1 has an axially extending receiving space 11 and a first opening 12 connecting the inside and outside of the receiving space 11.

[0050] The light guide assembly 2 is disposed within the receiving space 11. The conductive assembly 3 includes a power transmission structure 33 and at least one conductive part 31 fixedly connected to the housing assembly 1, the conductive part 31 being disposed on the outside of the receiving space 11. A first end of the power transmission structure 33 is electrically connected to the conductive part 31, and a second end of the power transmission structure 33 extends into the inside of the receiving space 11 through a first opening 12 to achieve an electrical connection with the cable 7 (mentioned below), ensuring that the electrical energy transmitted by the cable can reach the conductive part 31 through the power transmission structure 33 and be transmitted to the optical communication device.

[0051] Specifically, optical signals and electrical energy are transmitted from the outside and inside of the housing space 11, respectively, to avoid mutual interference. The conductive part 31 and the light guide component 2 are located at the same end of the housing assembly 1 in the housing space 11, so that the conductive part 31 and the light guide component 2 can share a single plug-in component on the same side. The photoelectric channel can be established with a single plug-in, which simplifies the plug-in operation and avoids misoperation that could cause the photoelectric channel to be obstructed, thus effectively realizing the transmission of photoelectric signals.

[0052] Depending on the structural and functional requirements, the number of conductive parts 31 can be one, two, three, or more. For example, when there are multiple conductive parts 31... Figures 1 to 4 As shown, they can be simultaneously distributed on the upper side of the light guide component 2, for example... Figures 11 to 12 , Figures 19 to 23As shown, some of the conductive parts 31 can be distributed on the upper side of the light guide component 2, and some can be distributed on the lower side of the light guide component 2. In addition, the conductive parts 31 can also be distributed evenly on the left side, right side, or all around the light guide component 2.

[0053] It is important to understand that the different transmission methods of optical signals and electrical energy result in different required docking environments. Optical signals require high-precision coupling transmission, while electrical energy, in addition to requiring a certain docking precision, also needs to consider the impact of the operating environment on voltage breakdown, short circuits, and safety. Therefore, the conductive part 31 and the light guide component 2 are located at the same end of the housing assembly 1 within the receiving space 11, and the conductive part 31 and the light guide component 2 are located on the inner and outer sides of the receiving space 11, respectively. This ensures that the photoelectric channel can be established with a single insertion, and also ensures that the insertion of the two components will not interfere with each other.

[0054] After being connected to the conductive part 31, the power transmission structure 33 enters from the outside of the receiving space 11 and extends axially rearward to connect the cable 7. Thus, the conductive part 31 is exposed for interfacing with corresponding equipment, such as optical communication equipment. Except for the portion in contact with the conductive part 31, the remaining parts of the power transmission structure 33 are arranged outside the receiving space 11, ensuring safe placement within the insulated housing assembly 1.

[0055] In addition, the housing assembly 1 has a first opening 12 that connects the inner and outer sides of the receiving space 11. The housing assembly 1 and the power transmission structure 33 are manufactured separately, and the power transmission structure 33 is inserted through the first opening 12. The power transmission structure 33 is a slender metal strip that can be appropriately bent to be designed into a shape that can reasonably extend inside the housing assembly 1, taking into account both safety and assembly efficiency, and has good manufacturability.

[0056] It should be noted that in the various embodiments of this application, the extending direction of the accommodating space 11 of the housing component 1 is the axial direction, the direction from the power transmission structure 33 to the conductive part 31 is forward, and the opposite is backward; the optical communication device mentioned in the various embodiments of this application can be an optical communication device, an optical module, etc.

[0057] The conductive part 31 and the cable 7 form an electrical transmission channel to realize the transmission of electricity. The electricity here can be electrical energy supplied to the terminal equipment, or it can be an electrical signal containing customer business data.

[0058] The conductive part 31 and the cable 7 form an electrical transmission channel to realize the transmission of electricity. The electricity here can be the power supplied to the optical communication equipment, or it can be an electrical signal containing customer service data.

[0059] Taking the power supply for optical communication equipment as an example, in the prior art, the operation of optical communication equipment itself requires a power supply, especially in 5G applications, where there are many corresponding optical connectors and electrical connectors for supplying terminal equipment. Such optical communication equipment can be called terminal equipment, AP (Access Point), such as indoor antennas, cameras, and PC (Personal Computer) terminals. In the embodiment of this application, the conductive part 31 is electrically connected to the electrical connector (mentioned below); the electrical energy received by the cable 7 is transmitted to the electrical connector through the conductive part 31 to power the terminal equipment; the optical fiber 23 in the ferrule 22 of the light guide assembly 2 is optically coupled to the optical connector (mentioned below) to establish a channel for transmitting optical signals. The optical signal emitted by the terminal equipment is transmitted to the optical connector, and then the optical signal enters the optical fiber 23 to achieve transmission; thus completing the corresponding optical signal reception, conversion, and transmission process.

[0060] One possible implementation, such as Figures 1 to 12 ,as well as Figures 19 to 23 As shown, the outer shell assembly 1 includes a separate first shell portion 13 and a second shell portion 14. A conductive portion 31 is disposed on the outer wall surface of the first shell portion 13. By designing it in a split form, the difficulty of mold making is reduced. A first opening 12 is formed at the connection between the first shell portion 13 and the second shell portion 14, making the size of the first opening 12 relatively large and easy to adjust. For the slender conductive structure 33, it can be slightly tilted and inserted into the first shell portion 13 or the second shell portion 14. After installation, the second shell portion 14 or the first shell portion 13 is assembled, so that the two are connected as one.

[0061] Among them, the shell component 1 can take various forms, such as... Figures 1 to 10 In the illustrated non-limiting embodiment, the first shell portion 13 is a shell having a first subspace 131, and the second shell portion 14 is a shell having a second subspace 141.

[0062] The first subspace 131 and the second subspace 141 are connected to form the receiving space 11. The first shell 13 and the second shell 14 are connected axially. The first shell 13 is in front and the second shell 14 is behind. The rear seat 4 (mentioned below) is connected to the second shell 14. The conductive part 31 is disposed on the side wall of the first shell 13 and protrudes forward from the front end face of the first shell 13. The light guide assembly 2 is at least partially disposed in the receiving space 11, and the ferrule 22 (mentioned below) of the light guide assembly 2 should protrude from the front end face of the first shell 13 to facilitate insertion with optical communication equipment.

[0063] It is understandable that the first shell 13 and the second shell 14 are two shell sections, and their connection is a 360° ring. Therefore, by designing the shape of the overlap between the first shell 13 and the second shell 14, a groove can be set at any circumferential angle to facilitate the formation of the first opening 12 so that the power transmission structure 33 can pass through, making the setting more flexible and the structure simple.

[0064] The first housing 13 and the second housing 14 can be connected by a snap-fit, with a first fixing hole 133 formed on the side wall of the first housing 13 and a first protrusion 142 formed at the front end of the second housing 14 to mate with the first fixing hole 133. Of course, considering that the first housing 13 and the second housing 14 are not frequently separated, ultrasonic welding, laser welding, adhesive bonding, etc. can also be used. The power transmission structure 33 enters the inner side of the receiving space 11 from the connection between the first housing 13 and the second housing 14, and extends rearward along the side wall of the second housing 14 to achieve electrical connection with the cable 7.

[0065] In order to prevent the power transmission structure 33 in the second shell 14 from interfering with the light guide component 33, a clearance groove 15 is formed in the second subspace 141 for the power transmission structure 33 to pass through.

[0066] In such Figures 11 to 12 ,as well as Figures 19 to 23 In the illustrated non-limiting embodiment, the first shell portion 13 is a shell with a top opening 132 on the side wall, and the second shell portion 14 is a top plate. The second shell portion 14 is disposed on the top opening 132 to form a receiving space 11 that is open from front to back and substantially closed on all sides. By reasonably designing the shapes of the top opening 132 and the second shell portion 14, the first opening 12 can still be left after the two are fitted together so that the first end of the power transmission structure 33 can pass through.

[0067] A conductive part 31 is disposed on the side wall of the first housing 13 having a top opening 132, so that the power transmission structure 33 extending from the connection between the first housing 13 and the second housing 14 can be electrically connected to the conductive part 31 with the shortest possible distance. The conductive part 31 protrudes forward from the front end face of the first housing 13. A conductive part 31 is connected to the upper and lower sides of the first housing 13 respectively, thereby effectively preventing voltage breakdown.

[0068] The first housing 13 and the second housing 14 can be connected by snap-fit, ultrasonic welding, laser welding, adhesive bonding, or other methods. The power transmission structure 33 enters the inner side of the receiving space 11 and extends rearward along the side wall of the first housing 13 to achieve electrical connection with the cable 7. A clearance groove 15 is formed inside the first housing 13 to avoid the power transmission structure 33.

[0069] In one possible embodiment, the conductive part 31 is a metal needle, which is fixed on the first housing part 13. The two are fixed to each other, resulting in a simple structure and low cost.

[0070] One possible implementation, such as Figures 1 to 12 As shown, mounting holes 134 are formed on the side wall of the first housing portion 13;

[0071] The conductive part 31 includes a rear end 314, a needle tube 311, a needle tip 312 inserted into the needle tube 311, and an elastic element 313 disposed within the needle tube 311. The rear end 314 is disposed at the end of the needle tube 311 away from the needle tip 312. The needle tip 312 of the power transmission structure 33 is electrically connected to the rear end 314. The needle tube 311 is fixed within the mounting hole 134, and the needle tip 312 protrudes forward from the front end face of the first housing part 13 to facilitate insertion with optical communication equipment.

[0072] The conductive part 31 is configured such that the end face of the needle 312 is retractable relative to the mounting hole 134; on the one hand, this avoids hard contact during assembly. On the other hand, since the optical coupling accuracy requirements between the light guide assembly 2 and the optical connector (mentioned below) are high, by making the needle 312 elastically retractable, the mechanical stress generated during the contact between the electrical connector and the needle 312 can be prevented from being transmitted to the first housing part 13 through the mounting hole 134, thereby preventing it from affecting the insertion of the optical port and resulting in good optical coupling accuracy.

[0073] The cross-section of the needle 312 is a long cylinder with a circular or polygonal shape, and the material can be copper, steel, aluminum, etc., which have good electrical conductivity.

[0074] In some non-limiting embodiments, the rear end 314 should be at least partially exposed outside the mounting hole 134 to facilitate connection with the power transmission structure.

[0075] The first end of the power transmission structure 33 is bent inward and extends upward to form a baffle 331, the shape of which can be an inverted L-shape or a W-shape, depending on the design structure. The rear end 314 abuts against the baffle 331. Specifically, the mounting hole 134 is fixedly connected to the needle tube 311, and the rear end 314, which is fixed to one end of the needle tube 311, is fixed relative to the first housing 13. The position of the connection between the first housing 13 and the rear end 314 can be controlled by the design, thereby determining the distance from the first housing 13 to the rear end 314. As long as the baffle 331 is arranged exactly between the first housing 13 and the rear end 314, and the thickness of the baffle 331 is greater than the distance between the first housing 13 and the rear end 314, the baffle 331 will fit tightly against the rear end 314, ensuring unobstructed electrical transmission.

[0076] like Figure 5 , Figure 9 and Figure 10As shown, a recessed groove 144 can be formed on the second housing 14 to facilitate the passage of the power transmission structure 33. Since the power transmission structure 33 is a long metal strip, the recessed groove 144 can be opened along the axial direction to limit the left and right swaying of the power transmission structure 33. The rear end 314 abuts against the front of the baffle 331, and the second housing 14 abuts against the rear of the baffle 331, thereby limiting the axial swaying of the power transmission structure 33. In order to further limit the vertical swaying, a cover plate 146 can be provided at the front end of the elastic buckle 145 on the second housing 14. The elastic buckle 145 is used for snap-fit ​​fixing when the optical communication equipment is connected to the optoelectronic connector. The cover plate 146 extends forward to the top of the baffle 331, and together with the bottom end of the housing assembly 1, it restricts the baffle 331 from swaying in the up and down direction, thereby stably restricting the baffle 331 at this position without displacement. To ensure a tighter fit between the baffle 331 and the rear end 314, a flat surface 143 is formed on the side of the second housing 14 facing the first housing 13 to better mate with the baffle 331. In addition, the baffle 331 can be designed as a slightly curved plate with a thickness greater than that of the rear end 314 and the flat surface 143, causing the baffle 331 to deform within it. This elastic force ensures a tighter fit between the baffle 331 and the rear end 314, ultimately ensuring a smooth electrical transmission channel.

[0077] One possible implementation, such as Figures 19 to 23 As shown, the first end of the power transmission structure 33 is integrally connected to the conductive part 31. The power transmission structure 33 is a slender metal part, while the conductive part 31 is an integrally extended metal sheet. It can be understood that in order to make the connection between the conductive part 31 and the electrical connector (mentioned below) more tightly, the conductive part 31 can be designed as an arc-shaped structure. The conductive part 31 interacts with the electrical connector, causing the conductive part 31 to deform and thus providing a certain elasticity, ensuring that the electrical transmission channel between the conductive part 31 and the electrical connector is unobstructed.

[0078] One possible implementation, such as Figures 1 to 23 As shown, the optoelectronic connector includes a cable 7, an optical fiber 8, a retaining sleeve 5 extending along the axial direction, and a rear seat 4 having a first channel 41 extending along the axial direction; the receiving space 11, the first channel 41, and the second channel 51 are interconnected.

[0079] A second opening 42 is formed on the side wall of the rear seat 4, which connects the inner and outer sides of the first channel 41. The rear seat 4 is detachably connected to the outer shell assembly 1.

[0080] Depending on the difference between the first housing portion 13 and the second housing portion 14, the rear seat 4 is connected to either the first housing portion 13 or the second housing portion 14. For example... Figures 1 to 10 The rear seat 4 is snapped into the second shell 14, or it can be joined by ultrasonic welding, laser welding, adhesive bonding, etc. Figures 11 to 12 , Figures 19 to 23The rear seat 4 is snapped into the first shell 13. Similarly, it can also be welded by ultrasonic welding, laser welding, adhesive bonding, etc.

[0081] like Figures 1 to 17 As shown, the second end of the power transmission structure 33 enters the inner side of the first channel 41 through the receiving space 11 and exits to the outer side of the first channel 41 through the second opening 42. In order to ensure that the power transmission structure 33 extends axially, a bent section 332 can be formed in the middle of the power transmission structure 33. The bent section 332 passes through the second opening 42. The two sections of the power transmission structure 33, which are separated by the bent section 332, are arranged in parallel and staggered arrangement on the inner and outer sides of the first channel 41 and extend axially.

[0082] The fixing sleeve 5 is fitted on the end of the rear seat 4 away from the outer shell assembly 1. A gap 51 is formed between the fixing sleeve 5 and the side wall of the rear seat 4. The cable 7 and the optical cable 8 enter from the fixing sleeve 5 and are then connected to the optoelectronic circuits respectively.

[0083] In this configuration, the second end of the cable 7 is connected to the power transmission structure 33 within the gap 51. By designing the inner diameter of the fixing sleeve 5 and the outer diameter of the second seat 44 (mentioned below), a gap 51 is formed between the two to facilitate the connection between the cable 7 and the power transmission structure 33. The insulating fixing sleeve 5 is then tightened, meaning that the width of the gap 51 should be slightly smaller than the connection thickness between the cable 7 and the power transmission structure 33, thereby generating a squeezing sensation to ensure that the connection between the cable 7 and the power transmission structure 33 will not loosen, thus ensuring a smooth power transmission channel.

[0084] After passing through the first channel 41, the optical cable enters the receiving space 11 and couples with the light guide component 2. Alternatively, the optical cable can pass through the first channel 41 and couple with the light guide component 2 within the first channel 41. The specific design shall prevail.

[0085] In one possible embodiment, the rear seat 4 includes a first seat body 43 and a second seat body 44 that are interconnected, and a first channel 41 sequentially passes through the first seat body 43 and the second seat body 44 along the axial direction. The rear seat 4 can be injection molded from a plastic part; the first seat body 43 and the second seat body 44 can be integrally injection molded from plastic parts.

[0086] The first seat 43 is detachably connected to the outer casing assembly 1, such as Figure 1 , Figure 2 , Figure 10 as well as Figure 16 As shown, the first base 43 and the second shell 14 are snapped together. A second fixing hole 431 is formed on the side wall of the first base 43, and a second protrusion 111 corresponding to the second fixing hole 431 is formed on the side wall of the second shell 14. The two can be fixed by snapping together and are easy to disassemble and assemble. The connection between the two can also be ultrasonic welding, laser welding, adhesive bonding, etc.

[0087] The second opening 42 is located on the side wall of the second base 44, and the fixing sleeve 5 is fitted onto the second base 44, thereby ensuring that the power transmission structure 33 is not directly exposed and ensuring circuit safety. The second base 44 can be cylindrical or other shapes with a larger front dimension and a smaller rear dimension, so that the fixing sleeve 5 can be fitted more and more tightly onto the second base 44. The front end of the fixing sleeve 5 is a locking section 52 that can cooperate with the connecting seat 443, and the outer side of the end away from the locking section 52 has an anti-slip protrusion 53 for easy assembly.

[0088] One possible implementation, such as Figures 1 to 18 As shown, an axially extending capacitive groove 441 is formed on the outer side wall of the second base 44 for the passage of the power transmission structure 33. The capacitive groove 441 is connected to the second opening 42 so that the power transmission structure 33 extending from the second opening 42 can extend backward through the capacitive groove 441. The second base 44 is made of insulating material, which restricts the connection between the cable 7 and the second end of the power transmission structure 33 within the gap 51. On the one hand, it can ensure that the connection is not exposed and ensure safety. On the other hand, the force between them ensures that the connection strength between the cable 7 and the power transmission structure 33 is good.

[0089] In some non-limiting embodiments, the optoelectronic connector includes a wire terminal 61, through which the cable 7 is electrically connected to the second end of the power transmission structure 33, thereby ensuring sufficient strength at the connection point, allowing the power transmission channel to remain unobstructed, and preventing the occurrence of open circuits.

[0090] Since the wire terminal 61 usually occupies a large volume, the end of the capacitor tray 441 away from the first base 43 has a large-size section 442. The cable 7 is connected to the second end of the power transmission structure 33 through the wire terminal 61 within the large-size section 442. By controlling the width of the gap 51 within the large-size section 442 to be slightly smaller than the thickness of the wire terminal 61 and the power transmission structure 33, the fixing sleeve 5, the rear seat 4, and the wire terminal 61 interact with the power transmission structure 33, ensuring the connection strength between the wire terminal 61 and the power transmission structure 33.

[0091] In some non-limiting embodiments, the second seat 44 includes a connecting seat 443 and at least two cantilever 444 disposed opposite to each other. The fixing sleeve 5 covers the cantilever 444 and is connected to the connecting seat 443. A gap 51 is formed between the cantilever 444 and the inner wall of the fixing sleeve 5.

[0092] The two cantilever arms 444 have toothed grooves 445 on their opposing surfaces. The optical cable 8 enters from the rear end of the fixed sleeve 5 and then passes through the area between the cantilever arms 444 to enter the first channel 41. The fixed sleeve 5 covers the cantilever arms 444 and is connected to the connecting seat 443. Due to the interaction between the fixed sleeve 5, the rear seat 4, the wire terminal 61 and the power transmission structure 33, the cantilever arms 444 move inward and deform slightly. On the one hand, the toothed grooves 445 bite the optical cable 8 to prevent it from shaking; on the other hand, they can also provide a certain elasticity to ensure that the connection strength between the wire terminal 61 and the power transmission structure 33 in the gap 51 is good.

[0093] One possible implementation, such as Figure 11 , Figure 12 , Figure 19 and Figure 20 As shown, the light guide assembly 2 includes a tail shank 21, a ferrule 22, an optical fiber 23, a spring 26, and a base 27. The ferrule 22 is disposed on one end of the tail shank 21. The tail shank 21 is disposed in the receiving space 11. The optical fiber 23 is sequentially passed through the tail shank 21 and the ferrule 22 until the fiber core is flush with the end of the ferrule 22 furthest from the tail shank 21. The optical signal is transmitted in the fiber core until it reaches one end face of the ferrule 22, and then the optical signal is transmitted through a component that is optically coupled to the ferrule 22. This component can be the ferrule 22 of another optoelectronic connector or the optical port of an optical module. Corresponding grooves and blocks can be provided in the receiving space 11 to cooperate with the tail shank 21 to complete axial positioning, so that the tail shank 21 is disposed in the receiving space 11. The two ends of the spring 26 abut against the tail shank 21 and the base 27 respectively. The base 27 is located inside the rear seat 4, so that the ferrule 22 can float within a small range by compressing the spring 26, thereby making the coupling accuracy between the ferrule 22 and the optical connector high.

[0094] One possible implementation, such as Figures 10 to 23 As shown, the second end of the power transmission structure 33 enters the inner side of the first channel 41 through the receiving space 11. The cable 7 enters the inner side of the first channel 41 from the outer side of the rear seat 4, that is, the outer side of the first channel 41, through the second opening 42. Since the outer side of the cable 7 is wrapped with an insulating material, there will be no electrical leakage. The cable 7 does not pass through the inner side of the fixing sleeve 5, which helps to simplify its structure.

[0095] The fixing sleeve 5 is fitted on the end of the rear seat 4 away from the outer shell assembly 1. A gap 47 is formed between the base 27 and the side wall of the rear seat 4. The cable 7 and the second end of the power transmission structure 33 are connected in the gap 47.

[0096] Specifically, by setting the width of the base 27 and the inner diameter of the rear seat 4, a gap 47 can be formed between the two in the width direction perpendicular to the axial direction. The end of the cable 7 can be connected to a metal end plate 71. The width of the metal end plate 71 is similar to the width of the power transmission structure 33. The two are stacked together with a large contact area to avoid sharp sparks. The thickness of the metal end plate 71 and the power transmission structure 33 stacked together can be slightly greater than the width of the gap 47, so that the two remain connected under the pressure of the base 27 and the rear seat 4 and will not come loose, ensuring that the power transmission channel is unobstructed.

[0097] One possible implementation, such as Figures 1 to 10 as well as Figure 18 As shown, the light guide assembly 2 includes a clamping spring 24, a locking sleeve 25, a tail shank 21, a ferrule 22, and an optical fiber 23. The ferrule 22 is disposed on one end of the tail shank 21. The tail shank 21 is disposed in the receiving space 11. The ferrule 22 includes an inner hole (not shown) in the middle that allows the optical fiber 23 to pass through and protrude. The optical fiber 23 is sequentially passed through the tail shank 21 and the ferrule 22 until the fiber core is flush with the end of the ferrule 22 away from the tail shank 21.

[0098] The side wall of the tail shank 21 has a third opening 211. The clamping spring 24 can be a long and thin elastic strip. The clamping spring 24 is placed in the third opening 211. The locking sleeve 25 includes an inner hole 251. The size and shape of the inner hole 251 should match the shape of the tail shank 21. By fitting the locking sleeve 25 over the tail shank 21 to press the clamping spring 24 to clamp the optical fiber 23, it is ensured that the optical fiber 23 will not shake and the optical coupling accuracy is ensured.

[0099] An optical communication device, used in conjunction with the aforementioned optoelectronic connector, includes a body, an optical connector, and an electrical connector; the body has a socket for mating with a housing assembly 1, the optical connector is disposed within the socket for optical coupling with a light guide assembly 2, and the electrical connector is disposed within the socket for electrical connection with a conductive part 31.
