[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese patent application No. 202410611996.3, filed on May 16, 2024, entitled “Optical-electrical adapter, optical-electrical adapter assembly and communication device”, the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to an optical-electrical adapter, an optical-electrical adapter assembly and a communication device. BACKGROUND

[0004] Composite cable is a kind of cable that combines optical fiber and wire, which can simultaneously realize the transmission of optical signal and power supply (or electrical signal), and is convenient for construction and deployment. In recent years, it has been widely used. In actual application, an optical-electrical connector is generally arranged at the end of the composite cable, and an optical-electrical adapter connected with the optical-electrical connector is usually arranged in the communication device. After the optical-electrical connector is connected with the optical-electrical adapter, the optical connection and the electrical connection between the composite cable and the communication device can be realized.

[0005] In the current optical-electrical adapter, all the components for realizing the optical connection and the electrical connection are assembled and then installed into the communication device, which has the disadvantages of complex process and being not conducive to realizing automatic production. SUMMARY

[0006] The present application provides an optical-electrical adapter, an optical-electrical adapter assembly and a communication device with simple process and being conducive to realizing automatic production.

[0007] In a first aspect, the present application provides an optical-electrical adapter, comprising a fixing frame and a fiber sleeve, the fixing frame having a docking channel, and the fiber sleeve being fixed in the docking channel. The fixing frame is used for fixedly connecting with an optical-electrical connector, so that the fiber ferrule in the optical-electrical connector can be better inserted into the fiber sleeve. In addition, the fixing frame is used for fixedly connecting with a circuit board, so as to realize the fixed connection between the optical-electrical adapter and the circuit board. The circuit board can be a mainboard in the communication device, or can be a circuit board independent of the communication device. The fixing frame has a window penetrating into the docking channel, and the window is used for accommodating a conductive contact part. After the optical-electrical connector is connected with the optical-electrical adapter, the conductive structure in the optical-electrical connector extends into the docking channel, and the conductive structure and the conductive contact part in the conductive piece can abut through the window, so as to realize the electrical connection between the optical-electrical connector and the conductive piece.

[0008] In the optical-electrical adapter provided by the application, the fixing frame and the optical fiber sleeve are included, and the conductive member is not included. Therefore, the optical-electrical adapter is convenient to manufacture by automatic production process. In addition, since the conductive member is omitted, the fixing frame and the optical fiber sleeve are only assembled effectively, which is convenient for assembly and can effectively reduce the assembly process.

[0009] Alternatively, it can be understood that the conductive member is included in some optical-electrical adapters. In actual application, the fixing frame, the optical fiber sleeve and the conductive member are assembled into an integrated structure, and then are installed on the mainboard of the communication equipment, and the fixing frame and the conductive member are fixedly connected with the mainboard. Therefore, there are many assembly processes, which is not conducive to automatic production. In addition, since the fixing frame and the conductive member are fixedly connected, structures connected with each other need to be arranged in the fixing frame and the conductive member, which increases the complexity of the structures of the fixing frame and the conductive member. In the optical-electrical adapter provided by the application, the fixing frame does not have the corresponding structure that needs to be fixedly connected with the conductive member. Therefore, the fixing frame has the advantages of simple structure and easy manufacturing.

[0010] In specific arrangement, the fixing frame can have one window or multiple windows. When the fixing frame has multiple windows, the multiple windows are used to accommodate multiple conductive contact portions, respectively. That is, the number of the windows in the fixing frame is the same as the number of the conductive members on the circuit board, and the windows and the conductive members are arranged one by one.

[0011] In an example, the fixing frame has a protruding column, which is used to be fixedly connected with the circuit board. The protruding column has the advantages of simple structure and easy manufacturing. Therefore, the optical-electrical adapter is convenient to manufacture by automatic production process, and has good structural strength and reliability.

[0012] In specific arrangement, the extension direction of the protruding column is perpendicular to the extension direction of the connecting channel. Alternatively, the extension direction of the protruding column is consistent with the thickness direction of the circuit board, so that the fixing frame can be installed on the circuit board in a direction perpendicular to the circuit board, and interference between the window and the conductive member can be effectively prevented, which is convenient for assembly.

[0013] In the second aspect, the application provides an optical-electrical adapter assembly, which includes the circuit board and the optical-electrical adapter. The circuit board includes a dielectric substrate and a conductive member, and the conductive member is fixedly connected with the dielectric substrate. The conductive member has a conductive contact portion, and the conductive contact portion is accommodated in the window.

[0014] In the optoelectrical adapter assembly provided in the application, the conductive member is connected with the medium substrate, so that the fixed connection between the conductive member and the medium substrate can be realized, and the electrical connection between the conductive member and the conductive circuit in the medium substrate can also be realized. Therefore, the circuit board can be an integral structure when being manufactured. In addition, the optoelectrical adapter comprises a fixing frame and a fiber sleeve, and the external optoelectrical connector and the fiber ferrule in the communication device can be butted in the fiber sleeve, so that the optical connection between the optoelectrical connector and the communication device can be realized. In addition, the conductive member has a conductive contact part which is accommodated in the window, so that the conductive structure in the optoelectrical connector can be in contact with the conductive contact part through the window, so as to realize the electrical connection between the optoelectrical connector and the conductive member. By integrating the conductive member in the circuit board, the conductive member can be conveniently connected with the medium substrate, so as to realize the fixed connection between the conductive member and the medium substrate and the electrical connection between the conductive member and the conductive circuit. Meanwhile, the circuit board can be manufactured by using the automatic production process, so that the convenience is good. In addition, there is no connection structure between the conductive member and the fixing frame, so that only the position accuracy between the medium substrate and the conductive member and the position accuracy between the medium substrate and the fixing frame need to be ensured in actual application. The conductive member has the advantages of low manufacturing precision requirement and high tolerance.

[0015] In the specific arrangement, the conductive member can be elastic, so as to improve the electrical connection reliability between the optoelectrical adapter assembly and the optoelectrical connector. For example, the conductive member further comprises a fixed part and an elastic part. The conductive contact part is connected with the fixed part through the elastic part. The fixed part is fixedly connected with the medium substrate and connected with the conductive circuit. That is, the fixed part can be fixedly connected with the medium substrate and electrically connected with the conductive circuit, so as to realize the fixed connection and the electrical connection between the conductive member and the medium substrate. In addition, by arranging the elastic part, the elastic part can apply an elastic force to the conductive contact part, so that the conductive contact part is in close contact with the conductive structure in the optoelectrical connector, so as to ensure the electrical connection effect between the optoelectrical connector and the optoelectrical adapter assembly.

[0016] In the specific arrangement, the elastic part is used for the elastic displacement of the conductive contact part along the thickness direction of the medium substrate or perpendicular to the thickness direction of the medium substrate. In actual application, the deformation direction of the elastic part can be reasonably arranged according to the actual situation, so that the flexibility and the wide applicability are good.

[0017] In an example, the conductive contact part is extended into the butting channel by the window, so that the conductive member can realize the electrical connection with the conductive structure of the optoelectrical connector in the butting channel.

[0018] In an example, the conductive member is a conductive layer arranged on the surface of the medium substrate. When the circuit board is manufactured, the conductive member can be manufactured at the same time, so that the manufacturing convenience is good and the automatic production is easy to realize.

[0019] In an example, the medium substrate has a fixed hole extending along the thickness of the medium substrate, and the fixing frame has a protruding column which is inserted into the fixed hole. The fixing frame can be mounted on the circuit board in a direction perpendicular to the circuit board, and interference between the window and the conductive part can be effectively prevented, and the assembly is convenient.

[0020] In an example, the optoelectrical adapter assembly includes a plurality of optoelectrical adapters which are arranged on the medium substrate at intervals. The fixing frames of two adjacent optoelectrical adapters are connected. During manufacturing, the plurality of fixing frames can be integrally formed by injection molding, which facilitates large-scale production and assembly.

[0021] In a third aspect, the application provides a communication device including a housing and the above-mentioned optoelectrical adapter assembly. The optoelectrical adapter assembly is located in the housing, and the housing has an interface and the one end of the docking channel faces the interface. The communication device further includes an optical fiber connecting assembly which includes a shell and an optical fiber ferrule in the shell. The shell is used for plugging with the one end of the docking channel, and the optical fiber ferrule is used for being inserted into the optical fiber sleeve. In a specific arrangement, the optical fiber connecting assembly in the communication device can only include the optical fiber ferrule, and the optical fiber ferrule in the communication device and the optical fiber ferrule in the external optoelectrical connector can be docked in the optical fiber sleeve, so as to realize optical connection between the optoelectrical connector and the communication device. In addition, the circuit board in the optoelectrical adapter assembly is electrically connected with the devices in the communication device, and when the conductive structure in the external optoelectrical connector contacts the conductive part, electrical connection between the optoelectrical connector and the communication device can be realized. In addition, in a specific arrangement, the optical fiber connecting assembly can further include an optoelectrical converter, the optoelectrical converter in the optical fiber connecting assembly is connected with the optical fiber ferrule, and the optoelectrical converter can be used for converting electrical signals into optical signals and providing the optical signals to the optical fiber ferrule. Alternatively, the optoelectrical converter can also convert optical signals received by the optical fiber ferrule into electrical signals and provide the electrical signals to the processor and other devices in the communication device.

[0022] In an example, the communication device further includes a mainboard, and the circuit board is a part of the mainboard, or the circuit board is connected with the mainboard. That is, the circuit board can be a component of the mainboard, or the circuit board and the mainboard can be independent of each other. When the circuit board and the mainboard are independent components, the circuit board and the mainboard can be fixedly connected and electrically connected by welding, which has good use flexibility.

[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the drawings.

[0045] In a conventional fiber to the room (FTTR) scenario, the optical fiber and the wire are usually laid and deployed separately to respectively realize the signal connection between the communication devices and the power supply connection of the communication devices. However, the separate arrangement of the optical fiber and the wire has the problems of complex threading and installation, complicated deployment work, etc. Therefore, the composite cable of optical fiber-wire is currently widely used.

[0046] As shown in FIG. 1, it is a schematic diagram of a cross-sectional structure of a composite cable 01 according to an embodiment of the present application.

[0047] The composite cable 01 can include an optical fiber 011, a wire 012 and a wire 013 arranged in parallel. The optical fiber 011 can be used to transmit optical signals, and the wires 012 and 013 can be used to transmit electric energy or electric signals. The optical fiber 011, the wire 012 and the wire 013 are wrapped in an insulating outer skin 014, so that the insulating outer skin 014 can effectively protect the optical fiber 011, the wire 012 and the wire 013.

[0048] The composite cable 01 can well solve the communication and power supply problems, effectively improve the convenience when threading and installing the cable, and is very convenient when deployed.

[0049] As shown in FIG. 2, it is a fiber to the room-business (FTTR-B) scenario according to an embodiment of the present application. Specifically, in this scenario, it can include a master gateway 02, a plurality of optical sockets 03 and a plurality of slave gateways 04. The master gateway 02 and the optical socket 03 can be connected through the composite cable 01 to realize the communication connection and the electrical connection. In addition, the optical socket 03 and the slave gateway 04 can also be connected through the composite cable 01 to realize the communication connection and the electrical connection. It should be noted that in the example shown in FIG. 2, four slave gateways 04 and four optical sockets 03 are shown. However, in actual application, the configuration number and connection mode of the optical socket 03 and the slave gateway 04 can be reasonably set according to actual needs, which will not be described here.

[0050] Of course, the composite cable 01 can also be applied to other scenarios that require optical signal and electrical signal (or electrical energy) connection, and the present application does not limit this.

[0051] As shown in FIG. 3, in the current scheme, an optoelectrical connector 011 can be arranged at one end of the composite cable 01, and an optoelectrical adapter assembly 05 can be arranged in a communication device (such as an optical socket) 20. The optical and electrical connections between the composite cable 01 and the communication device 20 can be achieved by connecting the optoelectrical connector 011 and the optoelectrical adapter assembly 05.

[0052] In the optoelectrical adapter assembly 05, a plurality of components such as a fiber sleeve and a conductive sheet are usually included. Among them, the fiber sleeve is used to achieve optical connection, and the conductive sheet is used to achieve electrical connection. In the current optoelectrical adapter assembly 05, all components are usually assembled and then installed in the communication device, which has the disadvantages of complex process and being not conducive to automatic production.

[0053] Therefore, the embodiments of the present application provide an optoelectrical adapter assembly with a simple process and being conducive to automatic production.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the drawings and specific embodiments.

[0055] As shown in FIGS. 4 and 5, in an example provided by the present application, the optoelectrical adapter assembly 10 includes a circuit board 12 and an optoelectrical adapter 11. The circuit board 12 includes a dielectric substrate 121, a conductive circuit (not shown in the figure) and a conductive piece 122. The conductive circuit is arranged on the dielectric substrate 121, the conductive piece 122 is fixedly connected with the dielectric substrate 121, and the conductive piece 122 is electrically connected with the conductive circuit. As shown in FIG. 5, the optoelectrical adapter 11 includes a fixed frame 111 and a fiber sleeve 112, the fixed frame 111 has a docking channel 110, and the fiber sleeve 112 is fixed in the docking channel 110. The fixed frame 111 is fixedly connected with the circuit board 12, and the fixed frame 111 has a window 1111 penetrating into the docking channel 110. Among them, the conductive piece 122 has a conductive contact part 1221, and the window 1111 is used to accommodate the conductive contact part 1221. Specifically, in the examples provided in FIGS. 4 and 5, the conductive contact part 1221 extends into the docking channel 110 from the window 1111. Among them, the circuit board 12 can be a printed circuit board (PCB) or other structural types, and the present application does not limit the specific type and shape of the circuit board 12.

[0056] As shown in FIG. 5 and FIG. 6, in actual application, the optoelectrical adapter assembly 10 can be electrically connected with the external optoelectrical connector 011 and the device 21 in the communication equipment through the conductive member 122 in the circuit board 12. In addition, the optoelectrical adapter assembly 10 can be optically connected with the external optoelectrical connector 011 and the device 21 in the communication equipment through the optoelectrical adapter 11.

[0057] Specifically, in the electrical connection part, the fixed part 1222a and the fixed part 1222b of the conductive member 122 are electrically connected with the conductive circuit (not shown in the figure) on the medium substrate 121, and the device 21 in the communication equipment is also electrically connected with the conductive circuit, that is, the conductive member 122 is electrically connected with the device 21. When the optoelectrical connector 011 is plugged into the mating channel 110, the conductive structure 0112 in the optoelectrical connector 011 is in contact with the conductive contact part 1221 in the conductive member 122, so as to realize the electrical connection between the optoelectrical connector 011 and the conductive member 122, and further realize the electrical connection between the optoelectrical connector 011 and the device 21.

[0058] In the optical connection part, when the optoelectrical connector 011 is plugged into the mating channel 110, the fiber ferrule 0111 in the optoelectrical connector 011 is plugged into the fiber sleeve 112, and the fiber ferrule 22 in the communication equipment is plugged into the fiber sleeve 112 from the other end of the mating channel 110. That is, the fiber ferrule 0111 and the fiber ferrule 22 are mated in the fiber sleeve 112, so as to realize the optical connection between the optoelectrical connector 011 and the device 21. It should be noted that, in order to facilitate the understanding of the technical scheme of the present application, in the example in FIG. 6, one device 21 in the communication equipment is taken as an example for illustrative explanation, and the device 21 has the functions of optical connection and electrical connection at the same time. In actual application, the device 21 can also be considered as two or more devices.

[0059] In the optoelectrical adapter assembly 10 provided in the present application, the conductive member 122 is connected with the dielectric substrate 121, so that the fixed connection between the conductive member 122 and the dielectric substrate 121 can be realized, and the electrical connection between the conductive member 122 and the conductive circuit in the dielectric substrate 121 can also be realized. Therefore, the circuit board 12 can be an integral structure during the manufacturing process. That is, the conductive member 122 can be arranged on the dielectric substrate 121 to realize the fixed connection and the electrical connection between the conductive member 122 and the dielectric substrate 121. In addition, the optoelectrical adapter 11 includes the fixing frame 111 and the fiber sleeve 112, and the external optoelectrical connector 011 and the fiber ferrule 22 in the communication device can be butted in the fiber sleeve 112, so as to realize the optical connection between the optoelectrical connector 011 and the communication device. In addition, the conductive member 122 has the conductive contact part 1221, which is accommodated in the window 1111, so that the conductive structure 0112 in the optoelectrical connector 011 can be in contact with the conductive contact part 1221 through the window 1111 to realize the electrical connection between the optoelectrical connector 011 and the conductive member 122.

[0060] Alternatively, it can be understood that the circuit board 12 is not included in some optoelectrical adapter assemblies. For example, the optoelectrical adapter assembly includes the fixing frame 111, the fiber sleeve 112 and the conductive member 122, and the conductive member 122 is fixedly connected with the fixing frame 111. In actual application, the fixing frame 111, the fiber sleeve 112 and the conductive member 122 need to be assembled into an integral structure first, and then installed on the mainboard in the communication device, and the fixing frame 111 and the conductive member 122 are fixedly connected with the mainboard. At the same time, the conductive member 122 also needs to be electrically connected with the conductive circuit in the mainboard. There are many assembly processes, which is not conducive to automatic production. In addition, the conductive member 122 needs to be fixedly connected with the mainboard and the fixing frame 111, so that the mainboard and the fixing frame 111 need to be equipped with corresponding fixing structures to fix the conductive member 122, that is, the conductive member 122 is fixedly connected with the mainboard and the fixing frame 111 in a double fixing mode. In addition, the fixing frame 111 is also fixedly connected with the mainboard, that is, there is not only a direct fixed connection structure between the fixing frame 111 and the mainboard, but also a fixed connection between the fixing frame 111 and the mainboard through the conductive member 122, which has a high requirement on the precision of the fixing structures in the mainboard and the fixing frame 111, increases the manufacturing difficulty, and has a small tolerance. In addition, since the fixing frame 111 is fixedly connected with the conductive member 122, structures connected with each other need to be arranged in the fixing frame 111 and the conductive member 122, which increases the complexity of the structure of the fixing frame 111 and the conductive member 122.

[0061] In the optoelectrical adapter assembly 10 provided in the present application, the electrically conductive member 122 can be connected with the medium substrate 121 conveniently by being integrated in the circuit board 12, so as to realize the fixed connection between the electrically conductive member 122 and the medium substrate 121 and the electrical connection between the electrically conductive member 122 and the electrically conductive circuit, and meanwhile, the circuit board 12 can be manufactured by using the automatic production process conveniently, which has good convenience. In addition, there is no connection structure between the electrically conductive member 122 and the fixing frame 111, so that in actual application, only the positional accuracy between the medium substrate 121 and the electrically conductive member 122 and the positional accuracy between the medium substrate 121 and the fixing frame 111 need to be ensured. The electrically conductive member 122 has the advantages of low manufacturing accuracy requirement and high tolerance.

[0062] It should be noted that the electrically conductive contact part 1221 of the electrically conductive member 122 specifically refers to the part of the electrically conductive member 122 that is in contact with the electrically conductive structure 0112 in the optoelectrical connector 011, and the part of the electrically conductive member 122 that is not in contact with the electrically conductive structure 0112 is not considered as the electrically conductive contact part 1221. In addition, the electrically conductive contact part 1221 is accommodated in the window 1111, which specifically includes that the electrically conductive contact part 1221 extends into the window 1111, or a part of the electrically conductive contact part 1221 extends into the window 1111. Alternatively, the electrically conductive contact part 1221 does not extend into the window 1111.

[0063] In specific setting, the electrically conductive member 122 can be made of a conductive material such as copper or aluminum, so that the electrically conductive member 122 has good electrical conductivity. In addition, a material with good electrical conductivity such as silver or gold can be arranged on the surface of the electrically conductive contact part 1221 of the electrically conductive member 122, so as to reduce the contact resistance between the electrically conductive member 122 and the optoelectrical connector 011. In actual application, the material of the electrically conductive member 122 can be selected reasonably according to actual needs, which is not limited in the present application.

[0064] In actual application, the structure of the electrically conductive member 122 can be various.

[0065] For example, as shown in FIGS. 7 and 8, in an example provided in the present application, the electrically conductive member 122 has a substantially U-shaped structure. Two electrically conductive members 122 are shown in FIG. 7, and the structures of the two electrically conductive members 122 are basically the same, and one of the electrically conductive members 122 will be exemplarily described below.

[0066] Specifically, as shown in FIG. 8, the electrically conductive member 122 includes a fixed part, an elastic part 1223 and an electrically conductive contact part 1221. The fixed part includes two fixed parts 1222a and 1222b.

[0067] Please refer to FIG. 7 and FIG. 8, the fixed part 1222a and the fixed part 1222b are located at both ends of the conductive part 122, and both extend vertically towards the direction of the dielectric substrate 121. The elastic part 1223 is multiple, and is connected between the conductive contact part 1221 and the fixed part 1222a and the fixed part 1222b. The elastic part 1223 is formed by bending, and the elastic part 1223 is elastically deformed when the conductive contact part 1221 abuts against the conductive structure 0112 of the optoelectrical connector 011, so that the conductive contact part 1221 elastically contacts the conductive structure 0112 of the optoelectrical connector 011.

[0068] In addition, as shown in FIG. 7, FIG. 8 and FIG. 9, the dielectric substrate 121 has four fixed holes for connecting with two conductive parts 122 respectively. Taking one of the conductive parts 122 as an example, the dielectric substrate 121 includes the fixed hole 1211a and the fixed hole 1211b. Among them, the fixed part 1222a is inserted into the fixed hole 1211a, and the fixed part 1222b is inserted into the fixed hole 1211b. Specifically, the cross-sectional shape and the cross-sectional area of the fixed part 1222a and the fixed part 1222b are basically the same. The cross-sectional area of the fixed hole 1211a is smaller than the cross-sectional area of the fixed hole 1222b, and the fixed part 1222a is inserted into the fixed hole 1211a, so that the fixed part 1222a can be fixed in the fixed hole 1211a. The cross-sectional area of the fixed hole 1211b is slightly larger than the cross-sectional area of the fixed part 1222b, so that the fixed part 1222a can be effectively inserted into the fixed hole 1211a, and at the same time, the fixed part 1222b can be effectively inserted into the fixed hole 1211b. Specifically, when the conductive part 122 is manufactured, there may be a certain degree of dimensional error, and the cross-sectional area of the fixed hole 1211b is slightly larger than the cross-sectional area of the fixed part 1222b, which can provide a certain size tolerance for the insertion of the fixed part 1222b. In addition, in actual application, the fixed part 1222a and the fixed part 1222b can be welded and fixed in the fixed hole 1211a and the fixed hole 1211b by soldering and other materials, so as to strengthen the connection stability between the conductive part 122 and the dielectric substrate 121, and at the same time, improve the connection effect between the conductive part 122 and the conductive circuit in the dielectric substrate 121. In specific setting, the fixed part 1222a and the conductive circuit can be electrically connected, or the fixed part 1222b and the conductive circuit can be electrically connected, or the fixed part 1222a and the fixed part 1222b can be electrically connected with the conductive circuit. In actual application, the conductive part 122 can also be fixed on the dielectric substrate 121 by crimping, wave soldering, and surface mount soldering, and in specific setting, the connection mode between the conductive part 122 and the dielectric substrate 121 can be reasonably set according to actual needs, which is not described here.

[0069] In addition, in actual application, the conductive part 122 can also have other shapes.

[0070] For example, as shown in FIG. 10, in another example provided by the present application, the conductive member 122 is in a substantially L-shaped structure. The conductive member 122 includes a fixed portion 1222, a conductive contact portion 1221, and two elastic portions 1223 formed by bending and connecting between the conductive contact portion 1221 and the fixed portion 1222. Please refer to FIG. 9 and FIG. 10. The extension direction of the fixed portion 1222 is substantially parallel to the thickness direction of the dielectric substrate 121, i.e., the fixed portion 1222 is in a pin structure. In the specific arrangement, a fixed hole similar to the fixed hole 1211a can be arranged in the dielectric substrate 121, and the fixed portion 1222 can be inserted and fixed in the fixed hole.

[0071] Alternatively, as shown in FIG. 11, in another example provided by the present application, the conductive member 122 is in a substantially spoon-shaped structure. The conductive member 122 includes a fixed portion 1222, a conductive contact portion 1221, and two elastic portions 1223 formed by bending and connecting between the conductive contact portion 1221 and the fixed portion 1222. Please refer to FIG. 9 and FIG. 11. The extension direction of the fixed portion 1222 is substantially perpendicular to the thickness direction of the dielectric substrate 121. In the specific arrangement, the plane of the fixed portion 1222 can be fixed on the surface of the dielectric substrate 121 by means of surface mounting or welding.

[0072] Alternatively, as shown in FIG. 12, in another example provided by the present application, the conductive member 122 is in a substantially L-shaped structure. The conductive member 122 includes a fixed portion 1222, a conductive contact portion 1221, and an elastic portion 1223 formed by bending and connecting between the conductive contact portion 1221 and the fixed portion 1222. Please refer to FIG. 9 and FIG. 12. The extension direction of the fixed portion 1222 is substantially parallel to the thickness direction of the dielectric substrate 121, i.e., the fixed portion 1222 is in a pin structure. In the specific arrangement, a fixed hole similar to the fixed hole 1211a can be arranged in the dielectric substrate 121, and the fixed portion 1222 can be inserted and fixed in the fixed hole.

[0073] It should be noted that in the examples provided in FIG. 8 to FIG. 11, the bending direction of the elastic portion 1223 is towards or away from the dielectric substrate 121, so that the elastic portion 1223 can provide elastic displacement for the conductive contact portion 1221 along the thickness direction of the dielectric substrate 121. In the example provided in FIG. 12, the bending direction of the elastic portion 1223 is substantially perpendicular to the thickness direction of the dielectric substrate 121, so that the elastic portion 1223 can provide elastic displacement for the conductive contact portion 1221 along the direction perpendicular to the thickness direction of the dielectric substrate 121.

[0074] In general, the fixed part of the conductive part 122 can be one or two or more. When the conductive part 122 is arranged, the shape of the conductive part 122 can be selected according to the specific type of the optical and electrical connector to be connected, which will not be repeated here.

[0075] In addition, in the above examples, the conductive part 122 can be a sheet metal part, or a plastic part with a conductive material on the surface. Alternatively, it can be understood that the conductive part 122 and the dielectric substrate 121 in the circuit board 12 can be separately formed.

[0076] In other examples, the circuit board 12 can also be integrally formed.

[0077] For example, as shown in FIG. 13, in another example provided by the present application, the conductive part 122 is a conductive layer arranged on the surface of the dielectric substrate 121. For example, the conductive part 122 can be a gold finger or a strip electrode. In particular, the conductive part 122 can be made by using the process for making the circuit board 12, thereby having better manufacturing convenience, facilitating automation production, and being conducive to reducing the manufacturing cost and assembly process flow of the circuit board 12.

[0078] It should be noted that when the conductive part 122 is a conductive layer arranged on the surface of the dielectric substrate 121, it does not have elasticity itself, so in some examples, an elastic conductive structure can be selected in the optical and electrical connector to ensure the elastic contact between the conductive structure in the optical and electrical connector and the conductive part 122.

[0079] For example, as shown in FIG. 14, in an example provided by the present application, the optical and electrical connector 011 is connected to one end of the composite cable 01. The optical and electrical connector 011 includes a housing 0113, a fiber ferrule 0111 and a conductive structure 0112. The fiber ferrule 0111 and the conductive structure 0112 are arranged in the housing 0113. As shown in FIGS. 14 and 15, the fiber ferrule 0111 is arranged in the fiber sleeve 112 in the optical and electrical adapter 10, and the conductive structure 0112 is in contact with the conductive contact part 1221 of the conductive part 122. The conductive structure 0112 includes a conductive contact part 01121 and a bent elastic part 01122. After the optical and electrical connector 011 is inserted into the optical and electrical adapter assembly 10, the fiber ferrule 0111 is arranged in the fiber sleeve 112, and the conductive contact part 01121 of the conductive structure 0112 is elastically contacted with the conductive contact part 1221 of the conductive part 122 by the abutting channel 110 extending into the window 1111, thereby realizing the electrical connection between the optical and electrical connector 011 and the optical and electrical adapter assembly 10.

[0080] In addition, in actual application, the relative position between the conductive part 122 and the window 1111 can be various.

[0081] For example, as shown in FIG. 15, in one example provided by the present application, the conductive member 122 is a conductive layer disposed on the dielectric substrate 121, and the conductive layer only extends into the window 1111 and does not extend into the mating channel 110. After the optoelectrical connector 011 is plugged into the optoelectrical adapter assembly 10, the conductive contact portion 01121 of the conductive structure 0112 of the optoelectrical connector 011 is in contact with the conductive contact portion 1221 of the conductive member 122 through the window 1111.

[0082] That is, the conductive contact portion 1221 of the conductive member 122 can extend into the window 1111, or can not extend into the window 1111.

[0083] Alternatively, as shown in FIG. 6, in another example provided by the present application, the conductive member 122 is a U-shaped structure as shown in FIG. 8. Moreover, the conductive contact portion 1221 of the conductive member 122 extends into the mating channel 110 through the window 1111, and when the optoelectrical connector 011 is plugged into the mating channel 110, the conductive structure 0112 can be in contact with the conductive contact portion 1221 of the conductive member 122 in the mating channel 110.

[0084] That is, the conductive contact portion 1221 of the conductive member 122 can extend into the mating channel 110 through the window 1111.

[0085] In addition, as shown in FIG. 6, in one example provided by the present application, the window 1111 has a large area. That is, there is a clear gap between the conductive member 122 and the inner wall of the window 1111, so as to effectively prevent the positional interference between the fixing frame 111 and the conductive member 122.

[0086] It can be understood that in other examples, the inner wall of the window 1111 can also be in contact with the conductive member 122. In actual applications, the relative positions between the window 1111 and the conductive member 122 can be reasonably set according to actual conditions, which will not be described herein.

[0087] In addition, in the above examples, two conductive members 122 are included in the circuit board 12, two windows 1111 are included in the optoelectrical adapter 11, and the two windows 1111 are arranged in one-to-one correspondence with the two conductive members 122. In other examples, the optoelectrical adapter 11 can also include one window 1111, which can be arranged in correspondence with two conductive members 122 at the same time, i.e., the conductive contact portions 1221 of the two conductive members 122 are both accommodated in the one window 1111. Alternatively, in other examples, for one optoelectrical adapter 11, the circuit board 12 can also include one, three or more conductive members 122. When specifically arranged, the number of windows 1111 and conductive members 122 and the correspondence relationship can be reasonably adjusted according to actual conditions, and details are not described herein.

[0088] In addition, in actual applications, the connection mode between the fixing frame 111 and the medium substrate 121 can also be various.

[0089] For example, as shown in FIGS. 7 and 9, in an example provided by the present application, the fixing frame 111 and the medium substrate 121 are connected in a clamping manner. Specifically, the medium substrate 121 has four fixing holes 1212 extending along the thickness direction of the medium substrate 121, and the fixing frame 111 has four protruding columns 1112, which are specifically in the form of a clamping hook. When the protruding column 1112 is inserted into the fixing hole 1212, the clamping connection between the fixing frame 111 and the medium substrate 121 is achieved.

[0090] In addition, the protruding column 1112 extends along the thickness direction of the medium substrate 121, so that the fixing frame 111 can be inserted along the thickness direction of the medium substrate 121 and the conductive member 122 can pass through the window 1111 to achieve simple assembly between the fixing frame 111 and the medium substrate 121.

[0091] It can be understood that in other examples, the fixing frame 111 and the medium substrate 121 can also be fixedly connected in a screw, rivet, adhesive or welding manner, and details are not described herein.

[0092] It should be noted that in the above examples, one optoelectrical adapter 11 is included in the optoelectrical adapter assembly 10 as an example for illustrative description. In actual applications, the optoelectrical adapter assembly 10 can also include multiple optoelectrical adapters 11 and conductive members 122 adapted to the optoelectrical adapters 11.

[0093] For example, as shown in FIG. 16, in one example provided by the present application, four photoelectric adapters 11 are arranged at intervals in the photoelectric adapter assembly 10, and the four photoelectric adapters 11 are independent of each other. That is, each photoelectric adapter 11 is independently mounted on the medium substrate 121, and has good use flexibility. In actual application, the number of photoelectric adapters 11 can be increased or reduced according to actual needs.

[0094] Alternatively, as shown in FIG. 17, in another example provided by the present application, the four photoelectric adapters 11 are in an integrated structure. Specifically, two adjacent photoelectric adapters 11 are connected to each other by a connecting rib 113. Among the two adjacent photoelectric adapters 11, one end of the connecting rib 113 is connected to the fixing frame 111 in one of the photoelectric adapters 11, and the other end of the connecting rib 113 is connected to the fixing frame 111 in the other photoelectric adapter 11. That is, the fixing frames 111 of the two adjacent photoelectric adapters 11 are fixedly connected, so that the four photoelectric adapters 11 form an integrated structure. In production, the four fixing frames 111 and the three connecting ribs 113 can be integrally formed by injection molding, which is convenient for mass production and assembly.

[0095] Of course, in other examples, two photoelectric adapters 11 can also form an integrated structure, or three, five, or more photoelectric adapters 11 can also form an integrated structure, which will not be described here.

[0096] It should be noted that in the above examples, the photoelectric adapter 11 is combined with the circuit board 12 to realize the transmission of optical signals and electrical signals (or electrical energy). In other examples, the photoelectric adapter 11 can also be used independently. For example, in some application scenarios, only optical connection is required and no electrical connection is required, the photoelectric adapter 11 can be independently applied in a communication device, or the photoelectric adapter 11 can be applied in other cable assemblies that require optical connection.

[0097] In addition, in actual application, the photoelectric adapter assembly 10 can be applied in various types of communication devices to realize optical connection and electrical connection.

[0098] For example, as shown in FIG. 18 and FIG. 19, the communication device 20 provided by the embodiment of the present application is a kind of active optical splitter. Specifically, the active optical splitter 20 comprises a housing 23 and the optical-electrical adapter assembly 10. The optical-electrical adapter assembly 10 is fixed in the housing 20, so that the housing 20 can effectively protect the optical-electrical adapter assembly 10 from the invasion of external impurities such as dust or water vapor. In addition, the housing 23 has a plurality of interfaces 230, and one end of the mating channel 110 in the optical-electrical adapter assembly 10 faces the interface 230, so as to facilitate the external optical-electrical connector to be plugged into the mating channel 110 through the interface 230.

[0099] In addition, in the example provided by the present application, the communication device 20 further comprises a power module 24, and the housing 23 has an interface 231 matched with the power module 24. Through the interface 231, the external power supply device can supply power to the communication device 20.

[0100] In a specific arrangement, the shape of the interface 230 can be rectangular, so as to be matched with the rectangular optical-electrical connector.

[0101] Alternatively, as shown in FIG. 20, in another example, the shape of the interface 230 can also be circular, so as to be matched with the cylindrical optical-electrical connector 011.

[0102] In summary, in actual application, the shape of the interface 230 can be reasonably arranged according to the shape and type of the optical-electrical connector 011 to be matched, and the present application does not limit this.

[0103] In addition, as shown in FIG. 21, in a specific arrangement, the communication device 20 further comprises a fiber connector assembly 200, which is arranged in the housing 23 and is matched with the other end of the mating channel 110, i.e. the fiber connector assembly 200 and the external optical-electrical connector 011 can be effectively matched through the optical-electrical adapter assembly 10.

[0104] The fiber connection assembly 200 includes a housing 201 and a fiber ferrule 22 arranged in the housing 201. The housing 201 is inserted into one end of the mating channel 110, and the fiber ferrule 22 is inserted into the fiber sleeve 112. In a specific arrangement, the fiber connection assembly 200 can only include the fiber ferrule 22. Alternatively, in some examples, the fiber connection assembly 200 includes the fiber ferrule 22 and an optoelectronic transducer 21 for converting between optical signals and electrical signals. The optoelectronic transducer 21 is connected to the fiber ferrule 22 and can be used to convert electrical signals into optical signals and provide the optical signals to the fiber ferrule 22. Alternatively, the optoelectronic transducer 21 can also convert optical signals received by the fiber ferrule 22 into electrical signals and provide the electrical signals to a processor or other device in the communication device. In specific applications, the specific type of the fiber connection assembly 200 is not limited in the present application.

[0105] In addition, in actual applications, the circuit board 12 in the optoelectronic adapter assembly 10 can be used as a mainboard in the communication device, or the circuit board 12 can be part of the mainboard. Alternatively, the circuit board 12 and the mainboard can be two independent components, and the circuit board 12 can be connected to the mainboard by welding or other methods.

[0106] In specific applications, the arrangement between the circuit board 12 and the mainboard can be reasonably arranged according to actual needs, which will not be described here.

[0107] In various embodiments of the present application, the terms and / or descriptions of different embodiments are consistent and can be mutually referenced if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0108] In the present application, "a plurality of" refers to two or more. The association relationship between the associated objects is described, which means that there can be three relationships, for example, A and / or B, which can represent the following cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural.

[0109] It can be understood that the various numbers involved in the embodiments of the present application are only for convenient differentiation and do not limit the scope of the embodiments of the present application. The size of the serial number of the above processes does not mean the execution order, and the execution order of the processes should be determined by its function and inherent logic.
