[0023] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the combined state of an embodiment of the optoelectronic adapter of this application connected to an optoelectronic connector; Figure 2 This is an exploded view of one embodiment of the optoelectronic adapter of this application and the applicable optoelectronic connector. This application provides an optoelectronic adapter A, suitable for connection to an optoelectronic connector C, to provide optical signal and power transmission. The optoelectronic adapter A is suitable for installation on devices or apparatuses that transmit optical signals and require power, such as… Figure 1 and Figure 2 The photoelectric adapter A shown is mounted on the vehicle-mounted lens B (or radar), and the photoelectric connector C is connected to the photoelectric adapter A of the vehicle-mounted lens B to provide the power required by the vehicle-mounted lens B and transmit the images received by the vehicle-mounted lens B.

[0024] See Figure 2 In some embodiments, the optoelectronic connector C includes an inner frame C1, a housing C2, and a pin C3. The inner frame C1 has a conductive hole C11 and a third guide portion C12. The housing C2 is rotatable and elastically displaceable and fits over the inner frame C1. The pin C3 is located inside the inner frame C1.

[0025] See Figures 3 to 7 , Figure 3 This is a three-dimensional assembly structure diagram of one embodiment of the photoelectric adapter A of this application; Figure 4 An exploded perspective view of one embodiment of the photoelectric adapter A of this application. Figure 1 ; Figure 5 An exploded perspective view of one embodiment of the photoelectric adapter A of this application. Figure 2 ; Figure 6 Cross-sectional view of the combined structure of one embodiment of the optoelectronic adapter of this application. Figure 1 ; Figure 7 Cross-sectional view of the combined structure of one embodiment of the optoelectronic adapter of this application. Figure 2 The optoelectronic adapter A includes a mating housing 10, a body 20, an optical transceiver module 30, and two conductive terminals 40. The mating housing 10 includes a through hole 11. The body 20 includes a first portion 21, a second portion 22 connected to each other, and a through hole 23 connecting the first portion 21 and the second portion 22. The body 20 passes through the through hole 11 of the mating housing 10. The second portion 22 includes a receiving groove 221. The optical transceiver module 30 is disposed within the receiving groove 221 of the body 20. The optical transceiver module 30 includes a housing 31, an optical adapter terminal 32, an optical emitting component 33, and an optical receiving component 34. The optical adapter terminal 32, the optical emitting component 33, and the optical receiving component 34 are respectively disposed in the housing 31. The optical adapter terminal 32 extends out of the through hole 23 and is located on one side of the first portion 21. Each conductive terminal 40 passes through the body 20, and a portion of each conductive terminal 40 is located within the through hole 11. Thus, an optoelectronic adapter A capable of simultaneously providing power and transmitting optical signals is provided.

[0026] See Figures 3 to 7 The mating housing 10 is used to support the body 20 and serves as the main contact component of the optoelectronic adapter A with the optoelectronic connector C. In some embodiments, the mating housing 10 includes a through hole 11 and a first body segment 12, an extension 13, and a second body segment 14 connected in sequence, with the through hole 11 penetrating and communicating through the first body segment 12, the extension 13, and the second body segment 14.

[0027] See Figures 3 to 7 In these embodiments, the first body segment 12 is used to sleeve the inner frame C1 of the optoelectronic connector C, and the second body segment 14 is used to connect to the body 20. In these embodiments, the first body segment 12 is a hollow cylindrical structure extending along the first direction D1, and the first body segment 12 is set along the contour of the through hole 11. In other embodiments, the appearance shape of the first body segment 12 of the mating shell 10 can be determined according to the shape of the optoelectronic connector C, and this invention is not limited thereto.

[0028] See Figures 3 to 7In some embodiments, the second segment 14 comprises at least one arcuate plate 141 and at least one notch 142. The arcuate plate 141 is used to engage with the body 20, and the notch 142 allows the optical receiving component 34 of the optical transceiver module 30 to pass through. In these embodiments, there are two arcuate plates 141, and each arcuate plate 141 is symmetrically arranged around the perforation 11. Here, each arcuate plate 141 is a quarter-circle arc, but this is not a limitation. In other embodiments, the number of arcuate plates 141 may be single. In these embodiments, the arc of the arcuate plate 141 is a three-quarter-circle arc, thereby forming a notch 142 between the two ends of the arcuate plate 141.

[0029] See Figures 3 to 7 In some embodiments, the inner surfaces of the first segment 12 of the mating housing 10 have a first width D1 in a second direction D2 perpendicular to the first direction D1, and the inner surfaces of the second segment 14 have a second width D2 in the second direction D2, with the second length D2 being greater than the first length D1. This difference in width between the inner surfaces of the first segment 12 and the second segment 14 ensures the correct orientation of the body 20 during assembly, achieving a foolproof assembly effect.

[0030] See Figures 3 to 7 The body 20 carries the optical transceiver module 30 and is attached to the docking housing 10. In some embodiments, the appearance of the first portion 21 of the body 20 generally corresponds to the inner surface shape of the first body segment 12 of the docking housing 10, and the appearance of the second portion 22 of the body 20 generally corresponds to the inner surface shape of the second body segment 14 of the docking housing 10. In some embodiments, the appearance of the first portion 21 is cylindrical, corresponding to the inner surface of the first body segment 12 of the docking housing 10, and the appearance of the second portion 22 is cylindrical, corresponding to the inner surface of the second body segment 14 of the docking housing 10. In these embodiments, the diameter of the second portion 22 is larger than the diameter of the first portion 21. Thus, when the body 20 is assembled to the docking housing 10, the first portion 21 of the body 20 must penetrate the first body segment 12 through the second body segment 14, while the second portion 22 is correspondingly accommodated in the second body segment 14 and abuts against the extension 13. In this way, the body 20 is stopped by the extension 13 of the docking housing 10 and can be prevented from detaching towards the first body segment 12.

[0031] See Figures 3 to 7 In some embodiments, the second body segment 14 of the docking shell 10 further includes a first locking portion 143, and the second part 22 of the body 20 further includes a second locking portion 222, wherein the first locking portion 143 of the docking shell 10 is locked to the second locking portion 222 of the body 20.

[0032] See Figures 3 to 7In some embodiments, the first latching portion 143 and the second latching portion 222 have a concave-convex mating structure. In these embodiments, the first latching portion 143 can be a groove, and the second latching portion 222 can be a protrusion that can be accommodated in the groove, but this application is not limited thereto. In other embodiments, the first latching portion 143 can also be a protrusion, and the second latching portion 222 can be a groove that can accommodate the protrusion.

[0033] See Figures 3 to 7 In some embodiments where the second latching portion 222 is a protrusion, the second latching portion 222 includes a ramp 2221, which includes opposing first sides 2222 and second sides 2223. In the first direction D1, the first side 2222 is closer to the first portion 21 than the second side 2223. Furthermore, in the second direction D2, the first side 2222 of the second latching portion 222 is closer to the optical transceiver module 30 than the second side 2223. In this way, when the main body 20 is assembled to the docking shell 10, the second locking part 222 of the second part 22 of the main body 20 will first contact the first locking part 143 of the docking shell 10 with the first side 2222. As long as the main body 20 is continuously subjected to force towards the docking shell 10 along the first direction D1, the inclined surface 2221 of the second locking part 222 can play a guiding role, thereby guiding the second locking part 222 to be inserted into the first locking part 143 to form a stable locking state, thereby making the main body 20 stably attached to the docking shell 10.

[0034] See Figures 3 to 7 In some embodiments, the first section 12 of the docking housing 10 further includes a first guide portion 121, and the first part 21 of the body 20 further includes a second guide portion 211, with the second guide portion 211 of the body 20 sleeved on the first guide portion 121 of the docking housing 10.

[0035] See Figures 3 to 7 In some embodiments, the first guide portion 121 is an elongated protrusion extending along a first direction D1, and the second guide portion 211 is a groove corresponding to the shape of the first guide portion 121. In these embodiments, when the body 20 is assembled onto the docking housing 10, the cooperation between the docking housing 10 and the body 20 through the first guide portion 121 and the second guide portion 211 ensures that the body 20 is assembled in the correct relative position. Furthermore, after the body 20 is assembled onto the docking housing 10, the possibility of rotation of the body 20 is restricted, thereby improving structural stability.

[0036] See Figure 1 , Figure 2 and cooperate Figures 6 to 8 , Figure 8This is a cross-sectional view of an embodiment of the optoelectronic adapter of this application connected to an optoelectronic connector. In some embodiments where the mating housing 10 includes a first guide portion 121, the inner frame C1 of the optoelectronic connector C has a third guide portion C12. When the body 20 is assembled to the mating housing 10, the second guide portion 211 of the body 20 is sleeved on a portion of the first guide portion 121. When the optical adapter A is assembled to the optical connector C, the third guide portion C12 of the inner frame C1 of the optical connector C is sleeved on the remaining portion of the first guide portion 121. Therefore, the first guide portion 121 of the mating housing 10 can simultaneously guide the optical connector C and the body 20 to be assembled in the correct position and ensure that the optical connector C and the body 20 cannot rotate, improving the stability of the overall structure.

[0037] In some embodiments, the optical transceiver module 30 serves as an optical network unit (ONU) for transmitting signals between itself and an optical line terminal (OLT) and for transmitting signals to various application interfaces.

[0038] See Figures 3 to 7 In some embodiments, the optical transceiver module 30 is a Bi-Directional Optical Sub-Assembly (BOSA), which simultaneously includes an optical transmitter optical subassembly (TOSA) 33 and an optical receiver optical subassembly (ROSA) 34. The optical transmitter optical subassembly 33 can convert electrical signals into optical signals, and the optical receiver optical subassembly 34 can convert optical signals into electrical signals, thereby becoming an optical transceiver module 30 capable of realizing optical-to-electrical conversion or electro-optical conversion.

[0039] See Figures 3 to 7 In some embodiments, the housing 31 of the optical transceiver module 30 houses a functional module for optical-to-electrical or electro-optical conversion. In these embodiments, the housing 31 is a hexagonal cube, with a portion of the optical adapter terminal 32 located within the housing 31 corresponding to the functional module, protruding from one side of the housing 31. A portion of the optical emitting assembly 33 is located within the housing 31 corresponding to the functional module, protruding from one side of the housing 31. The optical emitting assembly 33 and the optical adapter terminal 32 protrude from opposite sides of the housing 31, respectively. In some embodiments, the optical adapter terminal 32 is a hollow cylindrical structure extending along a first direction D1, while the portion of the optical emitting assembly 33 protruding from the housing 31 consists of multiple optical emitting terminals, which also extend along the first direction D1.

[0040] See Figures 3 to 7In some embodiments, a portion of the light receiving component 34 is located within the housing 31 corresponding to a functional module, and a portion protrudes from one side of the housing 31. The portion of the light receiving component 34 protruding from the housing 31 is a light receiving terminal. In these embodiments, the light receiving terminal is L-shaped and includes a first segment and a second segment connected together. The first segment protrudes from the housing 31 and extends along a second direction D2, and the second segment extends along a first direction D1. The free end of the second segment and the free end of the light emitting terminal of the light emitting component 33 are located on the same side of the housing 31.

[0041] See Figures 3 to 7 In some embodiments, the through hole 23 of the body 20, which passes through both the first part 21 and the second part 22, is circular. The second part 22 further includes an opening 223 that connects to a receiving groove 221. The receiving groove 221 has two opposing side walls 2211 and a bottom 2212, each of which is planar. The through hole 23 connects to the receiving groove 221. In these embodiments, when the body 20 is assembled on the docking shell 10, the position of the opening 223 of the body 20 corresponds to the position of one of the notches 142 of the docking shell 10. Thus, when the optical transceiver module 30 is housed within the cavity 221 of the main body 20, the housing 31 of the optical transceiver module 30 abuts against the side walls 2211 and the bottom 2212 of the cavity 221. The optical adapter terminal 32 passes through the through hole 23 penetrating the first part 21, the optical receiving terminal of the optical receiving assembly 34 protrudes from the opening 223 and the notch 142, and the optical emitting terminal of the optical emitting assembly 33 passes through the through hole 23 penetrating the second part 22. In this way, the optical transceiver module 30 is stably placed within the cavity 221 of the main body 20.

[0042] See Figures 3 to 7 In some embodiments, the body 20 further includes two channels 24, each channel 24 extending along a first direction D1 through the first portion 21 and the second portion 22 of the body 20, and the two channels are respectively located on opposite sides of the receiving groove 221. In these embodiments, each conductive terminal 40 is inserted into each channel 24, and one end of each conductive terminal 40 extends out of the first portion 21 for conductive connection to the optoelectronic connector C, and the other end extends out of the second portion 22 for conductive connection to the device end (this embodiment takes a vehicle-mounted lens as an example, but this case is not limited thereto).

[0043] See Figures 1 to 3In some embodiments, the optoelectronic adapter A further includes a housing assembly 50, in which the extension 13 of the docking housing 10 is a sheet structure. The housing assembly 50 connects to the extension 13 of the docking housing 10 and can cover the body 20, the optical transceiver module 30, and each conductive terminal 40. In some embodiments, the housing assembly 50 includes a first housing 51 and a second housing 52, both of which are hollow structures. The optoelectronic adapter A is housed within the first housing 51, the docking housing 10 is fixedly attached to the inner surface of the first housing 51, and the first segment 12 extends out of the first housing 51. The vehicle-mounted lens B is housed within the second housing 52 and is optically / electrically connected to the optoelectronic adapter A. The second housing 52 is combined with the first housing 51, thereby providing a fully modular product appearance.

[0044] It is worth noting that the structural form of the first housing 51 of the housing assembly 50 is not limited to the aforementioned embodiments. In some embodiments, the first housing 51 of the housing assembly 50 may also be formed directly from the extension 13 of the docking shell 10 into the shape of the housing, thereby reducing the assembly process of the docking shell 10 and the housing assembly 50 and providing different process or product requirements.

[0045] See Figures 1 to 3 In some embodiments, the first segment 12 of the mating housing 10 further includes a positioning portion 122, which is located on the outer surface of the first segment 12. In these embodiments, the positioning portion 122 is a protruding structure, and the housing C2 of the optoelectronic connector C has a groove C21. Thus, when the optoelectronic connector C is assembled to the optoelectronic adapter A, the positioning portion 122 of the optoelectronic adapter A is accommodated in the groove C21 to form a physical positioning. At the same time, the optoelectronic adapter A is inserted between the housing C2 and the inner frame C1 of the optoelectronic connector C by the mating housing 10, and the optical adapter terminal 32 of the optoelectronic adapter A is sleeved on the pin C3 to form an optical signal connection, and the conductive terminal 40 is inserted into the conductive hole C11 to form an electrical signal connection. Thus, the positioning portion 122 and the groove C21 ensure that the optoelectronic connector C and the optoelectronic adapter A are in the correct assembly position and ensure the stability after assembly.
