Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and in particular to an optoelectronic hybrid adapter and optical module. Background Technology

[0002] Optical fiber communication is a communication method that uses light waves as the information carrier and optical fibers as the transmission medium. The field of optical communication technology typically involves devices such as connectors, optical modules, and adapters.

[0003] Among them, the connector is a passive optical device that enables the connection between optical fibers. It has the function of connecting optical fibers with optical fibers, optical fibers with active devices, optical fibers with other passive devices, and optical fibers with instruments. The optical module is a very important optical signal interface device in optical fiber communication. It has an optical interface and an electrical interface. The optical interface connects to the optical fiber to transmit optical signals, and the electrical interface connects to external communication terminal equipment. The adapter is used to convert between the two connectors.

[0004] Currently, equipment such as 5G base stations contains a large number of plug-in optical and electrical lines. Because optical and electrical connections are separated, there are numerous connectors, categorized into optical and electrical types. Connecting these connectors and adapters requires precise pairing, making installation and maintenance cumbersome and prone to errors. Furthermore, both optical and electrical cables need to be laid at the access terminal, necessitating secondary optical cable laying for access terminals with existing cables. Therefore, optical-electrical composite cables have become the preferred solution for fiber-to-the-access-terminal connections, enabling both power and network connectivity with a single installation.

[0005] To connect these composite cables, one existing solution is to design the optical connector and electrical connector separately. The optical connector is plugged into the optical adapter to achieve optical signal coupling, while the electrical connector is plugged into the electrical adapter to achieve electrical signal coupling. However, using separate optical and electrical connectors requires plugging and unplugging twice to complete the connection with the adapter.

[0006] Another solution is to use hybrid optoelectronic connectors and adapters. However, in existing solutions, the electrical terminals of the connectors are exposed, posing a risk of electric shock and human safety during actual use. Furthermore, the fiber optic cables in fiber optic connectors require extremely high precision during the mating process, essentially needing micron-level coupling. Any force applied in a non-optical axis direction during the mating process will affect the fiber coupling efficiency and precision. Currently, the electrical terminals of hybrid optoelectronic connectors and adapters are asymmetrically distributed in the fiber coupling structure, causing insertion and removal stress during the insertion and removal process to affect the coupling precision of the fiber optic connector's optical channel.

[0007] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an optoelectronic hybrid adapter and optical module, which solves the problem in the prior art that the insertion and removal stress during the insertion and removal of electrical terminals affects the coupling accuracy of the optical channel in the optical fiber adapter.

[0009] The present invention adopts the following technical solution:

[0010] To address the aforementioned problems, in a first aspect, the present invention provides a photoelectric hybrid adapter, comprising: an adapter body 1, at least one retaining member 2, and at least two electrical terminals 3, wherein:

[0011] The adapter body 1 includes at least one receiving cavity 11 and at least two mounting slots 12, the mounting slots 12 being symmetrically arranged on both sides of the receiving cavity 11;

[0012] The retaining member 2 is housed within the receiving cavity 11, and a through hole is provided in the middle of the retaining member 2 to provide space for the coupling of optical signals;

[0013] The electrical terminals 3 are disposed within the mounting groove 12, and are symmetrically disposed on both sides of the retainer 2.

[0014] Furthermore, the electrical terminal 3 includes a fixing member 31 and at least one elastic claw 32, wherein:

[0015] The fixing member 31 extends outward to form the elastic claw 32, which has elastic deformation capability and the front end of the elastic claw 32 has an arc-shaped structure.

[0016] Furthermore, each of the fixing members 31 extends outward and in opposite directions to form two symmetrically distributed elastic claws 32, one elastic claw 32 for connecting to the electrical terminal 7 of the opposite optical device 6, and the other elastic claw 32 for connecting to the electrical terminal 7 of the local optical device 5.

[0017] Furthermore, each of the fixing members 31 extends outward and in opposite directions to form two symmetrically distributed elastic claws 32, and two elastic claws 32 are provided on the same side of each fixing member 31, so as to form four elastic claws 32 on the fixing member 31.

[0018] Furthermore, when the elastic claws 32 appear in pairs on one side of the fixing member 31, a gap is provided between the two elastic claws 32;

[0019] When the front end of the elastic claw 32 is subjected to force, the gap is used to provide space for the elastic deformation of the elastic claw 32.

[0020] Furthermore, the fixing member 31 is provided with a mounting hole 311, and the retaining member 2 is provided with a fixing block 21. The mounting hole 311 accommodates the fixing block 21 to fix the electrical terminal 3 on the retaining member 2.

[0021] Furthermore, the optoelectronic hybrid adapter also includes a collimation sleeve 4, which is disposed in the through hole of the retainer 2 and is used to guide the coupling of the input optical signal and the output optical signal.

[0022] Furthermore, the adapter body 1 also includes at least one first plug-in cavity 13 and at least one second plug-in cavity 14, and the receiving cavity 11 is disposed between the first plug-in cavity 13 and the second plug-in cavity 14;

[0023] The first insertion cavity 13 is used to accommodate the optical device 5 at this end, and the second insertion cavity 14 is used to accommodate the optical device 6 at the other end.

[0024] Furthermore, the adapter body 1 also includes at least one partition 15, which divides the adapter body 1 into different independent cavities, and each independent cavity is provided with a retainer 2 and two electrical terminals 3.

[0025] Each independent cavity is equipped with a receiving cavity 11, two mounting slots 12, a first insertion cavity 13 and a second insertion cavity 14. The receiving cavity 11 is located between the first insertion cavity 13 and the second insertion cavity 14, and the mounting slots 12 are symmetrically arranged on both sides of the receiving cavity 11.

[0026] In a second aspect, the present invention provides an optical module including an optoelectronic hybrid adapter as described in the first aspect, wherein a receiver or laser is integrated in the output terminal of the optoelectronic hybrid adapter.

[0027] In this invention, the optoelectronic hybrid adapter includes an adapter body 1, at least one retaining member 2, and at least two electrical terminals 3. The adapter body 1 includes at least one receiving cavity 11 and at least two mounting slots 12, which are symmetrically arranged on both sides of the receiving cavity 11. The retaining member 2 is housed within the receiving cavity 11, and a through hole is provided in the middle of the retaining member 2 to provide space for optical signal coupling. The electrical terminals 3 are disposed within the mounting slots 12 and are symmetrically arranged on both sides of the retaining member 2. The reasonable structure between the electrical terminals 3 and the retaining member 2 can reduce the impact of stress generated during the insertion and removal of the electrical terminals 3 on the coupling accuracy of the optical channel.

[0028] Furthermore, the two connectors only need to be mated twice to complete the coupling of input optical signals and output optical signals, as well as input electrical signals and output electrical signals, within an independent cavity of the optoelectronic hybrid adapter. This achieves simultaneous coupling of optical and electrical signals through a single mating. A single connector only needs to be inserted once to connect to the optoelectronic hybrid adapter, reducing the cumbersomeness of plugging and unplugging operations. Attached Figure Description

Detailed Implementation

[0046] 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.

[0047] In the description of this invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1:

[0050] Embodiment 1 of the present invention provides a photoelectric hybrid adapter, combined with Figures 1 to 7 The optoelectronic hybrid adapter includes: an adapter body 1, at least one retainer 2, and at least two electrical terminals 3, wherein:

[0051] The adapter body 1 includes at least one receiving cavity 11 and at least two mounting slots 12, the mounting slots 12 being symmetrically arranged on both sides of the receiving cavity 11; the retaining member 2 is housed in the receiving cavity 11, the retaining member 2 having a through hole in the middle for providing space for optical signal coupling; the electrical terminals 3 are disposed in the mounting slots 12, and the electrical terminals 3 are symmetrically arranged on both sides of the retaining member 2.

[0052] The shape of the receiving cavity 11 is adapted to the shape of the retaining member 2, the shape of the mounting groove 12 is adapted to the shape of the mounting groove 12, the electrical terminals 3 are symmetrically arranged on both sides of the retaining member 2, and the two electrical terminals 3 are symmetrical about the through hole of the retaining member 2.

[0053] like Figure 7 As shown, in this embodiment, the local optical device 5 and the opposite optical device 6 complete electrical signal coupling through the electrical terminal 3, and the local optical device 5 and the opposite optical device 6 complete optical signal coupling inside the through hole of the retainer 2. The electrical terminal 3 is symmetrically arranged about the optical channel, which can reduce the impact of stress generated during the insertion and removal of the electrical terminal 3 on the coupling accuracy of the optical channel.

[0054] Compared to traditional solutions that divide the adapter into optical signal adapters and electrical signal adapters, when using the optoelectronic hybrid adapter provided in this embodiment of the invention, the local optical device 5 and the remote optical device 6 only need to be docked with the optoelectronic hybrid adapter once each to simultaneously complete the coupling of optical and electrical signals, simplifying the connection process and reducing the cumbersomeness of plugging and unplugging operations.

[0055] In order to better achieve electrical connection between the electrical terminal 3 and other optical devices, combined with Figures 8-10 The electrical terminal 3 includes a fixing member 31 and at least one elastic claw 32, wherein: the fixing member 31 extends outward to form the elastic claw 32, the elastic claw 32 has elastic deformation capability, and the front end of the elastic claw 32 has an arc-shaped structure.

[0056] Specifically, the elastic claw 32 is an elongated structure extending from the body of the fixing member 31, forming a cantilever structure with the fixing member 31. The elastic claw 32 possesses elastic deformation capability; when force is applied to its front end, it undergoes a certain degree of elastic deformation. In this embodiment, an arc-shaped structure is provided on the side of the front end of the elastic claw 32, its structure being compatible with the front end structure of the electrical terminals 7 of other optical devices. The front ends of the electrical terminals 7 of other optical devices abut against the arc-shaped structure at the front end of the elastic claw 32 to complete the electrical connection between the electrical terminals 3 and 7.

[0057] Compared to the rigid electrical terminal 3, the electrical terminal 3 in this embodiment possesses a certain elastic deformation capability. In conventional technology, the rigid electrical terminal 3 is not easily deformed under external force, which can lead to insufficient tightness between the electrical terminals 3. In this embodiment, since the electrical terminal 7 is located within the mounting groove of the opposite optical device 6 or the local optical device 5, the electrical terminal 7 itself does not undergo elastic deformation. Figure 10 As shown, when the electrical terminal 7 of other optical devices abuts against the upper side of the elastic claw 32, the elastic claw 32 undergoes a certain degree of elastic deformation, making the electrical terminal 7 and the elastic claw 32 fit tightly together, increasing the reliability of the connection between the elastic claw 32 and other electrical terminals 7, so as to complete the reliable electrical connection between the electrical terminal 3 and other optical devices.

[0058] In an optional embodiment, the front end of the elastic claw 32 may also be configured as an outward arc, chamfer, rounded corner or curve, and its specific shape is adapted to the electrical terminals 7 of other optical devices that are connected to the electrical terminal 3.

[0059] In order to enable the electrical terminal 3 to be connected to two other electrical terminals 7 simultaneously, so as to complete the electrical connection between the two optical devices through the electrical terminal 3, combined with Figure 6 Each of the fixing members 31 extends outward and in opposite directions to form two symmetrically distributed elastic claws 32, one elastic claw 32 for connecting to the electrical terminal 7 of the opposite optical device 6, and the other elastic claw 32 for connecting to the electrical terminal 7 of the local optical device 5.

[0060] Specifically, a single electrode connection is established between the local optical device 5 and the remote optical device 6 via one electrical terminal 3, and an electrical connection between the local optical device 5 and the remote optical device 6 is established via two electrical terminals 3 on both sides of the retaining member 2. The local optical device 5 and the remote optical device 6 can be optoelectronic hybrid connectors.

[0061] To make the connection between the optoelectronic hybrid adapter and the optical device more robust, combined with Figure 9 and Figure 10 Each of the fixing members 31 extends outward and in opposite directions to form two symmetrically distributed elastic claws 32, and two elastic claws 32 are provided on the same side of each fixing member 31, so as to form four elastic claws 32 on the fixing member 31.

[0062] The advantage of providing four elastic claws 32 on the electrical terminal 3 is that two adjacent elastic claws 32 on the same side of the electrical terminal 3 are used to connect one electrode of an optical device, and the two electrodes of an optical device are connected through the two electrical terminals 3 on both sides of the retainer 2. The connection reliability is stronger. Even if the electrical connection of one elastic claw 32 fails, a normal connection can be achieved through the other elastic claw 32 on the same side. At the same time, the connection is also more secure. The two elastic claws 32 connected on the same side can be connected to the two electrical terminals 7 on the optical device, which makes the connection between the electrical terminal 3 and the electrical terminal 7 of the optical device more secure, and thus makes the connection between the hybrid optoelectronic adapter and other devices more secure.

[0063] On both sides of the retainer 2, the electrical terminals 3 are arranged symmetrically about the center of the through hole in the middle of the retainer 2. Similarly, the elastic claws 32 are also arranged symmetrically about the center of the through hole in the retainer 2. During the insertion and removal of the hybrid optoelectronic connector and the optical device, the elastic claws 32 and the electrical terminals 7 in the optical device will not be subjected to eccentric force, thereby reducing the optical channel coupling error caused by the eccentric force on the electrical terminals 3 and the electrical terminals 7 of the optical device during the insertion and removal process.

[0064] To establish a more robust connection between the elastic claw 32 and the electrical terminal 7 of the optical device, combined Figure 9 and Figure 10 When the elastic claws 32 appear in pairs on one side of the fixing member 31, a gap is provided between the two elastic claws 32; when the front end of the elastic claw 32 is subjected to force, the gap is used to provide space for the elastic deformation of the elastic claw 32.

[0065] When there is no gap between the two elastic claws 32 on the same side of the fixing member 31, when the two electrical terminals 7 are connected to the two elastic claws 32, the part between the two elastic claws 32 will bulge upward, or the electrical terminals 7 will not be able to be properly inserted into the space between the elastic claws 32 and the adapter body 1.

[0066] The ingenious aspect of setting a gap between two adjacent elastic claws 32 is that the gap provides space for the elastic deformation of the elastic claws 32. When the elastic claws 32 are connected to the electrical terminal 7, the arc-shaped structure on the front side of the elastic claws 32 is subjected to the lateral force applied by the electrical terminal 7 of the optical device. The elastic claws 32 undergo elastic deformation towards the gap side. Under the action of the elastic force, the elastic claws 32 tend to return to their original position and thus fit tightly against the surface of the electrical terminal 7, so as to establish a firm connection between the elastic claws 32 and the electrical terminal 7 of the optical device.

[0067] Meanwhile, the gap is smaller at the front end of the elastic claw 32 and larger at the root of the elastic claw 32. This is because when the elastic claw 32 is subjected to a lateral force applied by the electrical terminal 7, it should not elastically deform to the other side indefinitely. This would violate the original intention of setting the elastic claw 32: to establish a firm and reliable connection between the electrical terminal 7 and the elastic claw 32. Therefore, the elastic deformation capability of the elastic claw 32 should be reasonably set. At the same time, the gap at the front end of the elastic claw 32 is smaller than the gap at the root of the elastic claw 32, so that when the two elastic claws 32 on the same side of the fixing member 31 are subjected to a lateral force at the same time, under the condition of achieving a good connection, the front ends of the two elastic claws 32 will be as close as possible. Under the action of the electrical terminal 7, the elastic claw 32 is difficult to elastically deform to the gap side, thereby locking the electrical terminal 7 in the space between the adapter body 1 and the elastic claw 32. Meanwhile, while ensuring that the elastic claw 32 and the fixing member 31 are firmly connected and that the root of the elastic claw 32 can provide a certain rigidity, the gap at the root of the elastic claw 32 is designed to be large. This setting can reduce the materials required to produce the electrical terminal 3 and reduce the cost of the electrical terminal 3.

[0068] In this embodiment, to protect the electrical terminal 3, a protective layer is provided on the electrical terminal 3. The electrical terminal 3 is made of a conductive metal material, while the protective layer is made of an insulating non-metallic material. The front end of the elastic claw 32 is provided with an electrically exposed surface to facilitate electrical connection between the elastic claw 32 and the electrical terminals 7 of other optical devices. The main function of the protective layer is to isolate the electrical terminal 3 body from substances such as water or air, preventing the electrical terminal 3 body from getting damp and thus accelerating oxidation. On the other hand, the protective layer can also protect the electrical terminal 3 from mechanical damage to a certain extent.

[0069] In order to install the electrical terminal 3 inside the adapter body 1, combined with Figure 11 and Figure 12 ( Figure 12 (Only a part of the retaining member 2 is shown in the figure). The fixing member 31 is provided with a mounting hole 311, and the retaining member 2 is provided with a fixing block 21. The mounting hole 311 accommodates the fixing block 21 to fix the electrical terminal 3 on the retaining member 2.

[0070] During installation of the retainer 2, the mounting hole 311 is fitted onto the fixing block 21 to connect the two electrical terminals 3 on both sides of the retainer 2. Then, the assembly of the retainer 2 and the two electrical terminals 3 is fixed into the adapter body 1. The retainer 2 is fixed in the receiving cavity 11, and the two electrical terminals 3 provided on the retainer 2 are accommodated in the mounting groove 12. The shape of the mounting groove 12 is adapted to the shape of the electrical terminals 3, and the electrical terminals 3 are just accommodated in the mounting groove 12. Combined with the limiting position of the electrical terminals 3 by the fixing block 21, the electrical terminals 3 are fixed in the mounting groove 12.

[0071] In order to guide other optical devices during the coupling process of optical signals, combined with Figures 11-13 ( Figure 12 and Figure 13 (Only a portion of the retaining member 2 is shown in the image). The optoelectronic hybrid adapter also includes a collimating sleeve 4, which is disposed within the through hole of the retaining member 2 and is used to guide the coupling of the input optical signal and the output optical signal.

[0072] Among them, combined Figure 13 The ferrule 8 of the opposite optical device 6 and the ferrule 8 of the local optical device 5 are docked inside the collimation sleeve 4 to achieve optical channel coupling. At this time, the collimation sleeve 4 provides space to accommodate the ferrule 8 of the opposite optical device 6 and the ferrule 8 of the local optical device 5. Meanwhile, during the docking process between the two ferrules 8, the collimation sleeve 4 can play a guiding role.

[0073] In this embodiment, the collimating sleeve 4 is an open type, meaning that the collimating sleeve 4 has an axially extending slot that penetrates the side wall of the collimating sleeve 4. The significance of this slot is that it provides a certain degree of connection elasticity for the collimating sleeve 4. The collimating sleeve 4 needs to provide space for the mating of the two inserts 8 and requires guidance during the mating process. Because the mating accuracy requirements between the inserts 8 are high, the inner diameter of the collimating sleeve 4 is adapted to, or even slightly smaller than, the outer diameter of the two inserts 8. This causes the collimating sleeve 4 to be compressed by the inserts 8 when they are inserted and removed. Therefore, to provide space for the elastic deformation of the collimating sleeve 4 and to provide a certain degree of insertion and removal elasticity, an open type collimating sleeve 4 is selected in this embodiment. In an optional embodiment, the collimating sleeve 4 can also be a closed type.

[0074] In an optional embodiment, the collimating sleeve 4 is concentrated inside the retaining member 2. The through hole in the middle of the retaining member 2 can achieve the function of the collimating sleeve 4. The through hole in the middle of the retaining member 2 can guide the docking of the ferrule 8 between the two optical devices and provide a space for the ferrule 8 to be accommodated.

[0075] In this implementation, combined with Figure 7 and Figure 14 When other devices achieve optoelectronic connection within the optoelectronic hybrid adapter, electrical connection is achieved between electrical terminal 7 and electrical terminal 3, and optical channel coupling is achieved within collimation sleeve 4 by ferrule 8. At this time, electrical terminal 3, retainer 2, and a portion of collimation sleeve 4 are accommodated within local optical device 5 and opposite optical device 6. To facilitate better docking between the optoelectronic hybrid adapter and local optical device 5 and opposite optical device 6, the shape of the combination of two electrical terminals 3 and retainer 3 is consistent with the shape of the receiving cavity within the plug of local optical device 5.

[0076] In order to accommodate the local optical device 5 and the remote optical device 6 within the adapter body 1, combined with Figure 15 The adapter body 1 further includes at least one first insertion cavity 13 and at least one second insertion cavity 14, and the receiving cavity 11 is disposed between the first insertion cavity 13 and the second insertion cavity 14; the first insertion cavity 13 is used to receive the local optical device 5, and the second insertion cavity 14 is used to receive the opposite optical device 6.

[0077] The first insertion cavity 13 and the second insertion cavity 14 are connected to the outside of the adapter body 1. The local optical device 5 is partially housed in the first insertion cavity 13. When the elastic claw 32 is connected to the electrical terminal 7 of the local optical device 5, the electrical terminal 7 is located between the housing of the local optical device 5 and the elastic claw 32. The housing of the local optical device 5 is housed within the first insertion cavity 13 to complete the electrical connection between the local optical device 5 and the electrical terminal 3. The opposite optical device 6 is similarly housed in the second insertion cavity 14 to complete the electrical connection between the local optical device 5 and the opposite optical device 6 through the electrical terminal 3. The ferrule 8 of the opposite optical device 6 enters the collimating sleeve 4 of the receiving cavity 11 and docks with the ferrule 8 of the local optical device 5 to complete the coupling of the optical channel for optical signal transmission.

[0078] In order for the optoelectronic hybrid adapter to simultaneously connect multiple sets of peer optical devices 6 and local optical devices 5, combined with Figure 15The adapter body 1 also includes at least one partition 15, which divides the adapter body 1 into different independent cavities. Each independent cavity is provided with a retainer 2 and two electrical terminals 3. Each independent cavity is also provided with a receiving cavity 11, two mounting slots 12, a first plug-in cavity 13 and a second plug-in cavity 14. The receiving cavity 11 is located between the first plug-in cavity 13 and the second plug-in cavity 14, and the mounting slots 12 are symmetrically arranged on both sides of the receiving cavity 11.

[0079] Each independent cavity can complete the connection of a set of peer optical devices 6 and local optical devices 5. The adapter body 1 is divided into multiple independent cavities by the partition 15, so that the optoelectronic hybrid adapter can realize the connection of multiple sets of peer optical devices 6 and local optical devices 5. The significance is that when there are many cables, only one optoelectronic hybrid adapter is needed to complete the connection between many cables, reducing the number of optoelectronic hybrid adapters used. Since there is no need to replace multiple optoelectronic hybrid adapters, the overall connection efficiency of cables can be improved.

[0080] In this embodiment, a protrusion is provided on each of the two side walls on the outer side of the optoelectronic hybrid adapter body 1 to facilitate the operator to operate the optoelectronic hybrid adapter and quickly complete the connection between the optical device and the optoelectronic hybrid adapter.

[0081] Example 2:

[0082] Embodiment 2 of the present invention provides an optical module, including the optoelectronic hybrid adapter as described in Embodiment 1, wherein a receiver or laser is integrated in the output terminal of the optoelectronic hybrid adapter.

[0083] Specifically, when the optoelectronic hybrid adapter is used as a signal receiving terminal, a receiver is integrated at the first plug cavity 13 or the second plug cavity 14 of the optoelectronic hybrid adapter to receive the optical signal transmitted by the optical device connected to the optoelectronic hybrid adapter. This receiver is connected to the electrical terminal 3 and can convert the optical signal into an electrical signal to transmit the converted electrical signal to other terminal devices.

[0084] When the optoelectronic hybrid adapter is used as a signal transmitter, a laser is integrated at the first plug cavity 13 or the second plug cavity 14 of the optoelectronic hybrid adapter. The laser is connected to the electrical terminal 3 and can convert electrical signals into optical signals. The laser is used to connect with other transmitter devices to receive electrical signals from the transmitter devices, convert the electrical signals into specific optical signals, and transmit the optical signals through other optical devices connected to the optoelectronic hybrid adapter.

[0085] In this embodiment, the optoelectronic hybrid adapter also integrates an integrated circuit corresponding to the receiver or the laser, and can be powered through the electrical terminal 3 in the optoelectronic hybrid adapter to construct the optical module as an active module.

[0086] The adapter body 1 provided in this embodiment 2 includes: at least one receiving cavity 11 and at least two mounting slots 12, the mounting slots 12 being symmetrically arranged on both sides of the receiving cavity 11; the retaining member 2 being received in the receiving cavity 11, the retaining member 2 having a through hole in the middle for providing space for optical signal coupling; the electrical terminal 3 being disposed in the mounting slot 12, and the electrical terminal 3 being symmetrically arranged on both sides of the retaining member 2.

[0087] The shape of the receiving cavity 11 is adapted to the shape of the retaining member 2, the shape of the mounting groove 12 is adapted to the shape of the mounting groove 12, the electrical terminals 3 are symmetrically arranged on both sides of the retaining member 2, and the two electrical terminals 3 are symmetrical about the through hole of the retaining member 2.

[0088] In this embodiment, the local optical device 5 and the remote optical device 6 complete electrical signal coupling through the electrical terminal 3. The local optical device 5 and the remote optical device 6 complete optical signal coupling inside the through hole of the retainer 2. The electrical terminal 3 is symmetrically arranged about the optical channel, which can reduce the impact of stress generated during the insertion and removal of the electrical terminal 3 on the coupling accuracy of the optical channel.

[0089] Compared to traditional solutions that divide the adapter into optical signal adapters and electrical signal adapters, when using the optoelectronic hybrid adapter provided in this embodiment of the invention, the local optical device 5 and the remote optical device 6 only need to be docked with the optoelectronic hybrid adapter once each to simultaneously complete the coupling of optical and electrical signals, simplifying the connection process and reducing the cumbersomeness of plugging and unplugging operations.

[0090] The specific structure of the optoelectronic hybrid adapter is described in Example 1, and will not be repeated here.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
