Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of communication technology, and particularly to an optical module and an optical signal system. Background Technology

[0002] Currently, optical modules only support the transmission of optical signals. In fiber optic distributed systems, additional power supply is often required for terminal equipment to function properly. However, this increases both operational complexity and terminal costs. To address this issue, related technologies have proposed a solution of adding electrical modules to both the near-end and far-end units. This allows the near-end unit to provide power to the far-end unit via the electrical module. However, this solution still requires connecting both the optical module and the electrical module, resulting in operational complexity. Summary of the Invention

[0003] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0004] This invention provides an optical module and an optical signal system that can reduce operational complexity.

[0005] In a first aspect, embodiments of the present invention provide an optical module, comprising:

[0006] A first housing has a space for inserting a hybrid optoelectronic cable connector, and an optical device for optical transmission is disposed within the space. A positive electrode connection block has a first connection point and a third connection point. The first connection point is located within the space, and the third connection point is exposed outside the optical module. The first connection point is used for electrical connection with the hybrid optoelectronic cable connector with a conductive end, and the third connection point is used for electrical connection with a circuit board with a conductive interface. A negative electrode connection block has a second connection point and a fourth connection point.

[0007] Secondly, embodiments of the present invention provide an optical signal system, comprising:

[0008] A near-end unit is connected to an optical module as described in any of the first aspects above; a far-end unit is connected to an optical module as described in any of the first aspects above; a hybrid optical-electrical cable includes a first hybrid optical-electrical cable connector and a second hybrid optical-electrical cable connector, wherein the first hybrid optical-electrical cable connector is connected to the optical module in the near-end unit, and the second hybrid optical-electrical cable connector is connected to the optical module in the far-end unit.

[0009] This invention includes an optical module comprising a first housing, a positive electrode connector, and a negative electrode connector.

The positive electrode connector has a first contact point and a third contact point. The first contact point is located within the space, and the third contact point is exposed outside the optical module. The first contact point is used for electrical connection with the hybrid optoelectronic cable connector having a conductive end, and the third contact point is used for electrical connection with a circuit board having a conductive interface. The negative electrode connector has a second contact point and a third contact point. The second contact point is located within the space, and the fourth contact point is exposed outside the optical module. The second contact point is used for electrical connection with the hybrid optoelectronic cable connector having a conductive end, and the third contact point is used for electrical connection with a circuit board having a conductive interface. This device is used for electrical connection with a circuit board equipped with a conductive interface. That is, when the optoelectronic hybrid cable connector is inserted into the optical module, the optical device in the optical module can be connected to the optical fiber in the optoelectronic hybrid cable connector to enable optical transmission from the optical device in the optical module to the optoelectronic hybrid cable connector.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] It should be noted that although the flowchart shows a logical order, in some cases, the steps shown or described may be performed in a different order than that shown in the flowchart. In the description of the specification, claims, and the foregoing drawings, the use of terms such as "first," "second," etc., is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order in which the indicated technical features are presented.

[0028] Currently, optical modules only support the transmission of optical signals. In fiber optic distributed systems, additional power supply is often required for the terminal equipment to function properly. For example... Figure 1 As shown, the optical fiber and cable are separated. The first optical module 120 is electrically connected to the circuit board 140 of the near-end unit. The optical fiber is connected to the far-end unit 100 (such as a terminal device) and the first optical module 120 respectively. The far-end unit 100 is also connected to an additional cable, which provides power to the far-end unit 100. Optical transmission can be achieved between the near-end unit and the far-end unit 100 through the optical module. However, this scheme increases both the complexity of operation and the cost of the terminal.

[0029] Based on this, the present invention provides an optical module and an optical signal system. The optical module includes a first housing, a positive electrode connector block, and a negative electrode connector block. The first housing has a space for inserting a hybrid optoelectronic cable connector, and an optical device for optical transmission is disposed within this space. The positive electrode connector block has a first contact point and a third contact point. The first contact point is located within the space, and the third contact point is exposed outside the optical module. The first contact point is used for electrical connection with the hybrid optoelectronic cable connector having a conductive end, and the third contact point is used for electrical connection with a circuit board having a conductive interface. The negative electrode connector block has a second contact point and a third contact point. The second contact point is located within the space, and the fourth contact point is exposed outside the optical module. The second contact point is used for electrical connection with the hybrid optoelectronic cable connector having a conductive end. The fourth docking point is used to electrically connect with the circuit board equipped with a conductive interface. That is, when the optoelectronic hybrid cable connector is inserted into the optical module, the optical device in the optical module can dock with the optical fiber in the optoelectronic hybrid cable connector to enable the optical device in the optical module to transmit light to the optoelectronic hybrid cable connector. At the same time, the first docking point of the positive terminal block and the second docking point of the negative terminal block can be electrically connected to the conductive end of the optoelectronic hybrid cable connector, and the third docking point of the positive terminal block and the fourth docking point of the negative terminal block can be electrically connected to the conductive interface of the circuit board to enable the power supply in the circuit board to transmit light to the optoelectronic hybrid cable connector through the optical module. Therefore, the solution provided by the embodiment of the present invention can realize optical transmission and electrical transmission simultaneously through a single plug-in operation, reducing the complexity of operation.

[0030] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Reference Figure 2 , Figure 2 This is a schematic diagram of the structure of an optical module provided in one embodiment of the present invention. The diagram is provided for ease of description of the structural principle of the optical module. Figure 2 The optical module is illustrated using a hybrid optical-electrical cable connector 111. The optical module includes a first housing 129, a positive electrode connector 122, and a negative electrode connector 123.

[0032] The first housing 129 is provided with a space for inserting the optoelectronic hybrid cable connector 111, and an optical device 128 for optical transmission is provided in the space.

[0033] The positive electrode connection block 122 is provided with a first docking point and a third docking point. The first docking point is located in the space, and the third docking point is exposed to the optical module. The first docking point is used to make an electrical connection with the optoelectronic hybrid cable connector 111 which is provided with a conductive end, and the third docking point is used to make an electrical connection with the circuit board which is provided with a conductive interface.

[0034] The negative terminal connector 123 is provided with a second docking point and a fourth docking point. The second docking point is located in the space, and the fourth docking point is exposed to the optical module. The second docking point is used to make an electrical connection with the optoelectronic hybrid cable connector 111 which is provided with a conductive end, and the fourth docking point is used to make an electrical connection with the circuit board which is provided with a conductive interface.

[0035] In this embodiment, when the optoelectronic hybrid cable connector 111 is inserted into the optical module, the optical device 128 in the optical module can be connected to the optical fiber in the optoelectronic hybrid cable connector 111 to enable the optical device 128 in the optical module to transmit light to the optoelectronic hybrid cable connector 111. At the same time, the first connection point of the positive terminal block 122 and the second connection point of the negative terminal block 123 can be electrically connected to the conductive end of the optoelectronic hybrid cable connector 111, and the third connection point of the positive terminal block 122 and the fourth connection point of the negative terminal block 123 can be electrically connected to the conductive interface of the circuit board to enable the power supply in the circuit board to transmit light to the optoelectronic hybrid cable connector 111 through the optical module. Therefore, the solution provided by this embodiment of the invention can realize both optical transmission and electrical transmission in one insertion operation, reducing the complexity of operation.

[0036] Understandably, the circuit board can provide a power supply, such as a constant voltage source, so that the circuit board can transmit electricity to the optoelectronic hybrid cable connector 111 through the optical module.

[0037] It is understood that both the positive terminal block 122 and the negative terminal block 123 are conductors, such as metals, which can be used to transmit electrical signals, and no specific restrictions are made here.

[0038] It should be noted that the first and third docking points can be positioned relative to each other on the positive electrode connection block 122, and the second and fourth docking points can be positioned relative to each other on the negative electrode connection block 123. For example, the first and third docking points can be positioned at both ends of the positive electrode connection block 122, and the second and fourth docking points can be positioned at both ends of the negative electrode connection block 123. No specific restrictions are imposed here.

[0039] In one embodiment, the positive electrode connector 122 includes a first bent portion 135 extending into the space provided in the first housing 129 for inserting the optoelectronic hybrid cable connector 111. The first bent portion 135 is provided with a first mating point. The negative electrode connector 123 includes a second bent portion (not shown in the figure) extending into the space provided in the first housing 129 for inserting the optoelectronic hybrid cable connector 111. The second bent portion is provided with a second mating point. The first bent portion allows the first mating point to extend into the space, and the second bent portion allows the second mating point to be located in the space, so that the first mating point of the positive electrode connector 122 and the second mating point of the negative electrode connector 123 can be electrically connected to the conductive end of the optoelectronic hybrid cable connector 111. When the second mating point of the positive electrode connector 122 and the fourth mating point of the negative electrode connector 123 are electrically connected to the conductive interface of the circuit board, the circuit board transmits electricity to the optoelectronic hybrid cable connector 111 through the optical module.

[0040] In one embodiment, the optical module further includes an electrode carrier 126, which is installed within a first housing 129. The electrode carrier 126 is provided with a first mounting groove 131 and a second mounting groove 132. A positive electrode connector 122 is installed in the first mounting groove 131, and a negative electrode connector 123 is installed in the second mounting groove 132. This prevents the positive and negative electrode connectors 122 from shifting during handling, ensuring the stability of the product structure. Furthermore, when the optoelectronic hybrid cable connector 111 is inserted into the first housing 129 of the optical module, the first mating point of the positive electrode connector 122 can pass through the first mounting groove 131 and be electrically connected to the conductive end of the optoelectronic hybrid cable connector 111, and the second mating point of the negative electrode connector 123 can pass through the second mounting groove 132 and be electrically connected to the conductive end of the optoelectronic hybrid cable connector 111, thereby realizing electrical transmission between the optical module and the optoelectronic hybrid cable connector 111.

[0041] It is understood that the positive electrode connection block 122 and the negative electrode connection block 123 can have different implementations. For example, the positive electrode connection block 122 can be fixedly installed in the first mounting groove 131, and the negative electrode connection block 123 can be fixedly installed in the second mounting groove 132; or, the positive electrode connection block 122 can be slidably installed in the first mounting groove 131, and the negative electrode connection block 123 can be slidably installed in the second mounting groove 132. This embodiment does not impose specific limitations on this.

[0042] Based on the above embodiments, when the positive electrode connector 122 is slidably installed in the first mounting groove 131 and the negative electrode connector 123 is slidably installed in the second mounting groove 132, the positive electrode connector 122 further includes a first body 137 and a first baffle 136, and the negative electrode connector 123 further includes a second body 138 and a second baffle (not shown in the figure). The first baffle 136 is connected to the first bending portion 135 and the first body 137 respectively, and the second baffle is connected to the second bending portion and the second body 138 respectively. Furthermore, the optical module also includes a first elastic component 124 and a second elastic component 125. The first elastic component 124 is installed in the first mounting groove 131 and is connected to the first... The baffle 136 abuts against the second elastic member 125, which is installed in the second mounting groove 132 and abuts against the second baffle. When an external force is applied to the positive electrode connecting block 122, the first elastic member 124 is compressed or restored by the first baffle 136, so as to cause the positive electrode connecting block 122 to slide in the first mounting groove 131. Similarly, when an external force is applied to the negative electrode connecting block 123, the second elastic member 125 is compressed or restored by the second baffle, so as to cause the negative electrode connecting block 123 to slide in the second mounting groove 132. Therefore, the positive electrode connecting block 122 and the negative electrode connecting block 123 can slide by the application of external force and the deformation of the elastic member itself. Specifically, when the optoelectronic hybrid cable connector 111 is inserted into the optical module, the thrust generated by the optoelectronic hybrid cable connector 111 acts simultaneously on the positive electrode connector 122 and the negative electrode connector 123, so that the first baffle 136 of the positive electrode connector 122 compresses the first elastic member 124, and the second baffle of the negative electrode connector 123 compresses the second elastic member 125, thereby pushing the positive electrode connector 122 to slide in the first mounting groove 131 and pushing the negative electrode connector 123 to slide in the second mounting groove 132, until the third mating point of the positive electrode connector 122 and the fourth mating point of the negative electrode connector 123 are both electrically connected to the conductive interface of the circuit board; When the optoelectronic hybrid cable connector 111 is pulled out of the optical module, the thrust generated by the optoelectronic hybrid cable connector 111 disappears, and the first elastic component 124 and the second elastic component 125 slowly return to their original shape. Under the elastic force of the first elastic component 124 and the second elastic component 125, the positive electrode connecting block 122 slides in the first mounting groove 131, and the negative electrode connecting block 123 slides in the second mounting groove 132. The third mating point of the positive electrode connecting block 122 and the fourth mating point of the negative electrode connecting block 123 are both far away from the conductive interface of the circuit board, thereby avoiding accidental contact between the third mating point and the fourth mating point and the conductive interface of the circuit board. This embodiment does not impose specific limitations on this.

[0043] It should be noted that the first elastic component 124 and the second elastic component 125 can be a helical spring, a compression spring, a short spring, or other compressible elastic components, without specific limitations.

[0044] It should also be noted that the optical module may include multiple insulating plates 121, which cover the slider carrier to protect the positive electrode connection block 122 and the negative electrode connection block 123. The number of insulating plates 121 is not limited; there may be one or more, and no specific restriction is placed here. Furthermore, the insulating plates 121 may be made of insulating materials such as plastic or rubber, and no specific restriction is placed here.

[0045] In one embodiment, the positive electrode connection block 122 is further provided with a first inclined surface 133, and the third docking point is provided on the first inclined surface 133. Similarly, the negative electrode connection block 123 is further provided with a second inclined surface 134, and the fourth docking point is provided on the second inclined surface 134. Both the first inclined surface 133 and the second inclined surface 134 are exposed to the optical module. The third docking point on the first inclined surface 133 and the fourth docking point on the second inclined surface 134 can be electrically connected to the conductive interface on the circuit board.

[0046] It should be noted that, as Figure 8 As shown, the first conductive interface of the circuit board 140 may be provided with a first spring contact 141 for elastic connection with the third mating point, and the second conductive interface may be provided with a second spring contact 142 for elastic connection with the fourth mating point. In one example, as... Figure 6 and Figure 7 As shown, when the optoelectronic hybrid cable connector is plugged into the optical module, the optoelectronic hybrid cable connector can push the positive electrode connection block 122 and the negative electrode connection block 123, so that the third mating point on the first inclined surface 133 of the positive electrode connection block 122 is elastically connected to the first spring piece 141 on the circuit board 140, and the fourth mating point on the second inclined surface 134 of the negative electrode connection block 123 is elastically connected to the second spring piece 142 on the circuit board 140, thereby realizing the electrical connection between the optoelectronic hybrid cable and the optical module. Moreover, this design structure of the spring piece can enhance the interaction force between the spring piece and the mating point, so that the contact between the spring piece and the mating point is stable. This embodiment of the invention does not impose specific limitations on this.

[0047] It is understandable that both the first and second springs are conductors, such as metals, which can be used to transmit electrical signals, and no specific restrictions are made here.

[0048] In another embodiment, such as Figure 3 As shown, the positive electrode connection block 122 is also provided with a first protrusion 151, and the third docking point is provided on the first protrusion 151. Similarly, the negative electrode connection block 123 is also provided with a second protrusion 152, and the fourth docking point is provided on the second protrusion 152. Both the first protrusion 151 and the second protrusion 152 are exposed on the optical module. The third docking point on the first protrusion 151 and the fourth docking point on the second protrusion 152 can be electrically connected to the conductive interface on the circuit board.

[0049] It should be noted that the first protrusion 151 is disposed on the first body, and the first protrusion 151 can be disposed on the other end of the first body (not shown in the figure) opposite to the first baffle 136. The second protrusion 152 is disposed on the second body, and the second protrusion 152 can be disposed on the other end of the second body (not shown in the figure) opposite to the second baffle (not shown in the figure). No specific restrictions are made here.

[0050] In another embodiment, the positive electrode connection block 122 is further provided with a first recess, and the third docking point is provided in the first recess. Similarly, the negative electrode connection block 123 is further provided with a second recess, and the fourth docking point is provided in the second recess. Both the first recess and the second recess are exposed to the optical module. The third docking point on the first recess and the fourth docking point on the second recess can be electrically connected to the conductive interface on the circuit board.

[0051] It should be noted that the first recess is provided on the first body, and the first recess can be provided at the other end of the first body (not shown in the figure) opposite to the first baffle 136. The second recess is provided on the second body, and the second recess can be provided at the other end of the second body (not shown in the figure) opposite to the second baffle (not shown in the figure). No specific restrictions are made here.

[0052] In addition, refer to Figure 4 and Figure 5 Another embodiment of this application provides an optical signal system, which includes a near-end unit, a far-end unit 100, and a hybrid optical-electrical cable 112. Both the near-end unit and the far-end unit 100 are connected to optical modules as described in any of the above embodiments. The optical module connected to the near-end unit is a first optical module 120, and the optical module connected to the far-end unit 100 is a second optical module (not shown in the figure). The hybrid optical-electrical cable includes a first hybrid optical-electrical cable connector (not shown in the figure) and a second hybrid optical-electrical cable connector (not shown in the figure). The first hybrid optical-electrical cable connector is connected to the first optical module 120 in the near-end unit, and the second hybrid optical-electrical cable connector is connected to the second optical module in the far-end unit 100. The optical signal system has the beneficial effects brought by the optical modules in any of the above embodiments. For example, when the first optoelectronic hybrid cable connector is inserted into the first optical module 120 and the second optoelectronic hybrid cable connector is inserted into the second optical module, the optical devices in the first optical module 120 can be connected to the optical fibers in the first optoelectronic hybrid cable connector, and the optical devices in the second optical module can be connected to the optical fibers in the second optoelectronic hybrid cable connector. Therefore, optical transmission between the near-end unit and the far-end unit 100 can be achieved through the first optical module 120, the first electrical hybrid cable connector, the second optical module, and the second electrical hybrid cable connector. Therefore, the solution provided by the embodiments of the present invention can achieve optical transmission simultaneously through a single insertion operation.

[0053] It should be noted that the optoelectronic hybrid cable 112 includes optical fiber and cable. The two ends of the optoelectronic hybrid cable 112 are provided with a first optoelectronic hybrid cable connector and a second optoelectronic hybrid cable connector. The optical fiber is usually made of insulating materials such as ceramic or plastic, and no specific restrictions are made here.

[0054] It should be noted that there can be multiple remote units 100, and the number of remote units 100, the number of optical-electric hybrid cables 112, the number of first optical modules 120, and the number of second optical modules correspond one-to-one, without any specific restrictions.

[0055] In one embodiment, reference Figure 6 and Figure 7 Both the first and second optical modules include a positive electrode connector 122 and a negative electrode connector 123. The positive electrode connector 122 is provided with a first mating point (not shown in the figure) and a third mating point, and the negative electrode connector 123 is provided with a second mating point (not shown in the figure) and a fourth mating point. Both the near-end and far-end units include a circuit board (not shown in the figure). The circuit board is provided with a first conductive interface for electrical connection to the third mating point and a second conductive interface for electrical connection to the fourth mating point. Both the first and second optoelectronic hybrid cable connectors are provided with a first conductive end for electrical connection to the first mating point and a second conductive end for electrical connection to the second mating point. Therefore, the circuit board of the near-end unit and the first optical module, as well as the circuit board of the far-end unit and the second optical module, can be electrically connected to the third mating point via the first conductive interface. Electrical signals are transmitted through the electrical connection between the second conductive interface and the fourth mating point. When the first optoelectronic hybrid cable connector is plugged into the first optical module and the second optoelectronic hybrid cable connector is plugged into the second optical module, electrical signals can be transmitted between the first optical module and the first optoelectronic hybrid cable connector, as well as between the second optical module and the second optoelectronic hybrid cable connector, through the electrical connection between the first mating point of the positive terminal connector 122 and the first conductive end, and through the electrical connection between the second mating point of the negative terminal connector 123 and the second conductive end. That is to say, the first optical module and the second optical module can be electrically connected through the optoelectronic hybrid cable. Therefore, the power supply in the circuit board of the near-end unit can supply power to the circuit board of the far-end unit through the first optical module, the optoelectronic hybrid cable, and the second optical module, solving the problem of additional power supply processing for the terminal equipment, reducing the complexity of operation, and reducing the terminal cost. Furthermore, since when the first optoelectronic hybrid cable connector is plugged into the first optical module and the second optoelectronic hybrid cable connector is plugged into the second optical module, the optical signal in the first optical module can be transmitted to the second optical module through the optical fiber in the optoelectronic hybrid cable. Therefore, in this embodiment of the invention, the near-end unit and the far-end unit can achieve optical transmission and electrical transmission simultaneously through a single plugging operation, reducing operational complexity.

[0056] It should be noted that the first conductive interface of the circuit board 140 may be provided with a first spring contact 141 for elastic connection with the third mating point, and the second conductive interface may be provided with a second spring contact 142 for elastic connection with the fourth mating point, such as... Figure 8 As shown; or, the first conductive interface may be provided with a first pad for connection to the third mating point 153, and the second conductive interface may be provided with a second pad for connection to the fourth mating point 154, as shown. Figure 9 As shown, no specific restrictions are imposed here.

[0057] In one example, such as Figure 8 As shown, if the first conductive interface is provided with a first spring 141 and the second conductive interface is provided with a second spring 142, the positive electrode connection block can also be provided with a first inclined surface, and the third mating point is provided on the first inclined surface. The negative electrode connection block can also be provided with a second inclined surface, and the fourth mating point is provided on the second inclined surface. Both the first and second inclined surfaces are exposed to the optical module. When the first optoelectronic hybrid cable connector is plugged into the first optical module or the second optoelectronic hybrid cable connector is plugged into the second optical module, the first optoelectronic hybrid cable connector or the second optoelectronic hybrid cable connector can push the positive electrode connection block and the negative electrode connection block, so that the third mating point on the first inclined surface of the positive electrode connection block is elastically connected to the first spring 141 on the circuit board 140, and the fourth mating point on the second inclined surface of the negative electrode connection block is elastically connected to the second spring 142 on the circuit board 140, thereby realizing the electrical connection between the optoelectronic hybrid cable and the optical module. Moreover, this design structure of the spring can enhance the interaction force between the spring and the mating point, so that the contact between the spring and the mating point is stable. This embodiment of the invention does not impose specific limitations on this.

[0058] In another example, such as Figure 9 As shown, if the first conductive interface is provided with a first pad and the second conductive interface is provided with a second pad, the positive electrode connection block is also provided with a first boss, and the third mating point 153 is provided on the first boss. The negative electrode connection block is also provided with a second boss, and the fourth mating point 154 is provided on the second boss. Both the first boss and the second boss are exposed on the optical module. When the first optoelectronic hybrid cable connector is plugged into the first optical module or the second optoelectronic hybrid cable connector is plugged into the second optical module, the first optoelectronic hybrid cable connector or the second optoelectronic hybrid cable connector can push the positive electrode connection block and the negative electrode connection block, so that the third mating point 153 on the first boss of the positive electrode connection block is connected to the first pad on the circuit board 140, and the fourth mating point 154 on the second boss of the negative electrode connection block is connected to the second pad on the circuit board 140, thereby realizing the electrical connection between the optoelectronic hybrid cable and the optical module. This embodiment of the invention does not impose specific limitations on this.

[0059] In one embodiment, such as Figure 10As shown, both the circuit boards of the near-end unit and the far-end unit (not shown in the figure) are also equipped with protective cages 130. The protective cages 130 are provided with a first clearance position for avoiding the first conductive interface and a second clearance position for avoiding the second conductive interface. When the first optical module or the second optical module is inserted into the protective cage 130, the third docking point is directly opposite the first clearance position and the fourth docking point is directly opposite the second clearance position. Therefore, the first conductive interface on the circuit board can pass through the first clearance position to make an electrical connection with the third docking point on the optical module, and the second conductive interface can pass through the second clearance position to make an electrical connection with the fourth docking point on the optical module. Therefore, the embodiment of the present invention can realize electrical transmission between the circuit board and the optical module and protect the optical module.

[0060] It should be noted that the protective cage 130 can be a metal cage or other devices that can protect the optical module; no specific restrictions are made here.

[0061] In one embodiment, such as Figure 6 , Figure 8 and Figure 10 As shown, when the positive electrode connection block 122 is provided with a first inclined surface and the third docking point is provided on the first inclined surface, and the negative electrode connection block 123 is also provided with a second inclined surface and the fourth docking point is provided on the second inclined surface, and both the first and second inclined surfaces are exposed to the optical module, the optical module is inserted into the protective cage 130. When the optoelectronic hybrid cable connector is inserted into the optical module, the optoelectronic hybrid cable connector can push the positive electrode connection block 122 and the negative electrode connection block 123, so that the third docking point on the first inclined surface 133 of the positive electrode connection block 122 passes through the first clearance position of the protective cage 130 and is elastically connected to the first spring piece 141 on the circuit board 140, and the fourth docking point on the second inclined surface 134 of the negative electrode connection block 123 passes through the second clearance position of the protective cage 130 and is elastically connected to the second spring piece 142 on the circuit board 140. Therefore, the embodiment of the present invention can realize electrical transmission between the circuit board and the optical module, and can also protect the optical module.

[0062] In another embodiment, such as Figure 3 , Figure 9 and Figure 11As shown, when the positive electrode connection block 122 has a first protrusion 151 and a third mating point 153 is disposed on the first protrusion 151, and the negative electrode connection block 123 also has a second protrusion 152 and a fourth mating point 154 is disposed on the second protrusion 152, and both the first protrusion 151 and the second protrusion 152 are exposed outside the optical module, the optical module is inserted into the protective cage 130. When the optoelectronic hybrid cable connector is inserted into the optical module, the optoelectronic hybrid cable connector can push the positive electrode connection block 122 and the negative electrode connection block 123, so that the third mating point 153 on the first protrusion 151 of the positive electrode connection block 122 passes through the first clearance position of the protective cage 130 and is electrically connected to the first conductive interface on the circuit board 140, and the fourth mating point 154 on the second protrusion 152 of the negative electrode connection block 123 passes through the second clearance position of the protective cage 130 and is electrically connected to the second conductive interface on the circuit board 140. Therefore, the embodiment of the present invention can realize electrical transmission between the circuit board and the first optical module, and can also protect the optical module.

[0063] In one embodiment, such as Figure 12 and Figure 13 As shown, both the first and second optoelectronic hybrid cable connectors are provided with a first conductive end 113 for electrical connection with the first mating point and a second conductive end 114 for electrical connection with the second mating point. Both the first and second optoelectronic hybrid cable connectors are also provided with a first power interface 155 and a second power interface 156. The first power interface 155 is electrically connected to the first conductive end 113, and the second power interface 156 is electrically connected to the second conductive end 114.

[0064] It should be noted that the first power interface 155 can be used to electrically connect to the first mating point, and the second power interface 156 can be used to electrically connect to the second mating point; no specific restrictions are made here.

[0065] It should be noted that the first conductive terminal 113, the second conductive terminal 114, the first power interface 155, and the second power interface 156 can have different implementations. When the first mating point is electrically connected to the first power interface 155 and the second mating point is electrically connected to the second power interface 156, the power supply in the circuit board of the near-end unit can be input from the first power interface 155 and the second power interface 156 of the first optoelectronic hybrid cable connector through the first optical module, output from the first conductive terminal 113 and the second conductive terminal 114 of the first optoelectronic hybrid cable connector, transmitted to the second optoelectronic hybrid cable connector, input from the first conductive terminal 113 and the second conductive terminal 114 of the second optoelectronic hybrid cable connector, output from the first power interface 155 and the second power interface 156 of the second optoelectronic hybrid cable connector to the second optical module, and then transmitted to the far-end unit. The circuit board of the remote unit provides power to the remote unit; alternatively, the power in the circuit board of the near unit can be input from the first power interface 155 and the second power interface 156 of the first optoelectronic hybrid cable connector, output from the first power interface 155 and the second power interface 156, and transmitted to the second optoelectronic hybrid cable connector, then input from the first power interface 155 and the second power interface 156 of the second optoelectronic hybrid cable connector, and output from the first power interface 155 and the second power interface 156 of the second optoelectronic hybrid cable connector, until it is transmitted to the circuit board of the remote unit to provide power to the remote unit. The configuration can be set according to the actual situation, and the embodiments of the present invention do not impose specific limitations here.

[0066] When the first mating point is electrically connected to the first conductive terminal 113 and the second mating point is electrically connected to the second conductive terminal 114, the power supply in the circuit board of the near-end unit can be input from the first conductive terminal 113 and the second conductive terminal 114 of the first optoelectronic hybrid cable connector through the first optical module, output from the first conductive terminal 113 and the second conductive terminal 114 of the first optoelectronic hybrid cable connector, transmitted to the second optoelectronic hybrid cable connector, input from the first conductive terminal 113 and the second conductive terminal 114 of the second optoelectronic hybrid cable connector, output from the first conductive terminal 113 and the second conductive terminal 114 of the second optoelectronic hybrid cable connector to the second optical module, and then transmitted to the circuit board of the far-end unit to provide power to the far-end unit. Power supply; or, the power supply in the circuit board of the near-end unit can be input from the first conductive end 113 and the second conductive end 114 of the first optoelectronic hybrid cable connector through the first optical module, output from the first power interface 155 and the second power interface 156 of the first optoelectronic hybrid cable connector, transmitted to the second optoelectronic hybrid cable connector, input from the first power interface 155 and the second power interface 156 of the second optoelectronic hybrid cable connector, output from the first conductive end 113 and the second conductive end 114 of the second optoelectronic hybrid cable connector to the second optical module, and then transmitted to the circuit board of the remote unit to provide power to the remote unit. It can be set according to the actual situation, and the embodiments of the present invention do not make specific limitations here.

[0067] Therefore, the above embodiments can directly power the device through a single-ended product, solving the problem of additional power supply processing for the terminal device, reducing the complexity of operation, increasing product integration, reducing the size of the remote unit, and reducing the cost of the remote unit.

[0068] Based on the above embodiments, such as Figure 14 As shown, both the first and second optoelectronic hybrid cable connectors include an outer plastic 162 and an inner plastic 161. An optical fiber is connected in the middle of the inner plastic 161. A first conductive end 113 for electrical connection with the first mating point and a second conductive end 114 for electrical connection with the second mating point are provided on the upper surface of the outer surface of the inner plastic 161. Both the first conductive end 113 and the second conductive end 114 are exposed outside the outer plastic 162. When the first optoelectronic hybrid cable connector is plugged into the first optical module and the second optoelectronic hybrid cable connector is plugged into the second optical module, the first optical module and the second optical module can be electrically connected through the optoelectronic hybrid cable.

[0069] It should be noted that the outer surface of the inner plastic 161 may also be provided with a first power interface 155 and a second power interface 156, and both the first power interface 155 and the second power interface 156 are exposed on the outer plastic 162. For example, the first conductive end 113 and the second conductive end 114 may be located above the outer surface of the inner plastic 161, and the first power interface 155 and the second power interface 156 may be located on both sides of the outer surface of the inner plastic 161. These can be set according to actual needs, and no specific restrictions are made here.
