[0041] Referring to Figure 1 , Figure 1 An exploded schematic view of a photoelectric conversion device in an embodiment of the present application is shown. The photoelectric conversion device 10 provided by an embodiment of the present application includes a first optical module (not shown, same below), a second optical module (not shown, same below), and a connecting structure 100. The connecting structure 100 is used to connect the first optical module and the second optical module to each other, i.e., the connecting structure 100 is used to stably optically connect the first optical module and the second optical module, so that the optical signal can be transmitted between the first optical module and the second optical module.

[0042] The first optical module includes a first connector 200, and the second optical module includes a second connector 300. The connecting structure 100 is used to connect the first connector 200 and the second connector 300 to each other. The first connector 200 and the second connector 300 are both connected to the connecting structure 100, and the first connector 200 and the second connector 300 can be accurately aligned and stably optically connected through the connecting structure 100. In other words, the first connector 200 and the second connector 300 can be stably kept in the expected position and connected to each other through the connecting structure 100, so that the optical signal can be stably transmitted between the first optical module and the second optical module.

[0043] In an embodiment, the first connector 200 can be specifically an MPO connector, and the second connector 300 can be specifically an MT connector. Of course, the first connector 200 and the second connector 300 can also be specifically selected as different types of connectors according to the configuration of the optical module, which is not limited herein.

[0044] It should be understood that the connecting structure 100 described in various embodiments of the present application is not limited to being connected between optical modules. In the case of no contradiction, any two connectors can be connected to each other through the connecting structure 100 described in various embodiments.

[0045] Referring to Figure 1In one embodiment, the connecting structure 100 comprises an adapter 110 and a first clamping assembly 120 and a second clamping assembly 130. The first clamping assembly 120 and the second clamping assembly 130 are rotatably arranged on the adapter 110 to be opened and closed respectively. The first clamping assembly 120 corresponds to the first connector 200 for locking or releasing the first connector 200; the second clamping assembly 130 corresponds to the second connector 300 for locking or releasing the second connector 300.

[0046] The connecting structure 100 described above, the adapter 110 is used to connect the first connector 200 and the second connector 300, and the first clamping assembly 120 and the second clamping assembly 130 can be rotated relative to the adapter 110 to be opened and closed respectively. When the first clamping assembly 120 and the second clamping assembly 130 are closed, the first clamping assembly 120 and the second clamping assembly 130 can lock the first connector 200 and the second connector 300 at the same time, so that the first connector 200 and the second connector 300 are fixed relative to the adapter 110, thereby enabling the first connector 200 and the second connector 300 to maintain stable optical connection. When the first clamping assembly 120 and / or the second clamping assembly 130 is opened, the corresponding first connector 200 and / or the second connector 300 can be released relative to the adapter 110, thereby facilitating the disassembly of the first connector 200 and / or the second connector 300.

[0047] Please refer to Figure 2 and Figure 3 In one embodiment, the first clamping assembly 120 comprises a first clamping jaw 121, a second clamping jaw 122 and a retaining member 123. The first clamping jaw 121 and the second clamping jaw 122 are rotatably connected to the adapter 110. The retaining member 123 is elastically connected between the first clamping jaw 121 and the second clamping jaw 122, so that the first clamping jaw 121 and the second clamping jaw 122 are kept closed. In this way, when there is no external force driving the first connector 200, the first clamping jaw 121 and the second clamping jaw 122 can be kept closed by the retaining member 123, thereby improving the stability of the first clamping assembly 120 in locking the first connector 200. When it is necessary to disassemble the first connector 200, the elastic force of the retaining member 123 can be actively overcome to move the first clamping jaw 121 and the second clamping jaw 122 away from each other to open the first clamping assembly 120, thereby facilitating the disassembly of the first connector 200 from the adapter 110.

[0048] Of course, in other embodiments, the retaining member 123 can also keep the first clamping jaw 121 and the second clamping jaw 122 closed in other ways, such as magnetic force, etc. For ease of understanding, the retaining member 123 still keeps the first clamping assembly 120 closed in an elastic manner in each embodiment.

[0049] It should be noted that in some embodiments, the first clamping assembly 120 can only include the first clamping jaw 121 without the second clamping jaw 122. At this time, the first clamping jaw 121 can cooperate with the adapter 110 to jointly lock the first connector 200. That is, in the present embodiment, the adapter 110 is configured to cooperate with the first clamping jaw 121 to lock the first connector 200, and the first clamping jaw 121 can lock the first connector 200 when it rotates forward relative to the adapter 110, and can open and release the first connector 200 when it rotates reversely relative to the adapter 110. The above-mentioned forward and reverse are relative, and can be set according to actual needs, which will not be described here.

[0050] For the convenience of understanding and description, the first clamping assembly 120 still includes the first clamping jaw 121 and the second clamping jaw 122 in each embodiment. It can be understood that in each embodiment, the corresponding structure adapted and arranged on the adapter 110 can be directly used to replace the second clamping jaw 122 to cooperate with the first clamping jaw 121 to lock and release the first connector 200 without contradiction, so each embodiment will not be described one by one.

[0051] Please refer to Figure 4 and Figure 5 in combination with Figure 3 In one embodiment, the first clamping jaw 121 includes a first limiting portion 121a, a first rotating portion 121b and a first connecting portion 121c distributed in sequence. The first rotating portion 121b is rotationally connected with the adapter 110, that is, the first clamping jaw 121 constitutes a lever structure with the first rotating portion 121b as the fulcrum, and the first limiting portion 121a and the first connecting portion 121c are respectively located on both sides of the fulcrum, and the rotation of either one of the first limiting portion 121a and the first connecting portion 121c will drive the other to rotate. The first connecting portion 121c is connected with the retaining member 123, so that the retaining member 123 can pull the first connecting portion 121c to rotate towards the second clamping jaw 122.

[0052] In combination with Figure 4 When the first connecting portion 121c rotates towards the second clamping jaw 122, the first limiting portion 121a is used to abut and lock the first connector 200. That is, when the retaining member 123 elastically pulls the first connecting portion 121c to rotate towards the second clamping jaw 122, the elastic force can be transmitted to the first limiting portion 121a through the lever to make the first limiting portion 121a elastically abut the first connector 200, so that the first connector 200 is fixed with the adapter 110. In this way, the first clamping jaw 121 cooperates with the second clamping jaw 122 and the adapter 110 to lock the first connector 200.

[0053] In combination with Figure 2 and Figure 3When the first joint 200 needs to be disassembled, the first connecting part 121c can be driven to rotate in a direction away from the second clamping jaw 122, and the first limiting part 121a will move synchronously with the first connecting part 121c to separate from the first joint 200. In this way, the first joint 200 loses the locking effect of the first clamping assembly 120 and can be conveniently disassembled from the adapter 110.

[0054] In an embodiment, similar to the first clamping jaw 121, the second clamping jaw 122 comprises a second limiting part 122a, a second rotating part 122b and a second connecting part 122c distributed in sequence. The second rotating part 122b is rotationally connected with the adapter 110, and the second connecting part 122c is connected with the retaining member 123.

[0055] When the second connecting part 122c rotates in a direction close to the first clamping jaw 121, the second limiting part 122a is used to abut and lock the first joint 200.

[0056] When the second connecting part 122c rotates in a direction away from the first clamping jaw 121, the second limiting part 122a can be driven to separate from the first joint 200, facilitating the disassembly of the first joint 200. Please refer to Figure 3 and Figure 4 In an embodiment, the axis line where the first connecting part 121c and the second connecting part 122c are connected is the elastic axis, and the axis line where the first rotating part 121b and the second rotating part 122b are connected is the intermediate axis. When the first clamping assembly 120 is opened and closed, the elastic axis is located on different sides of the intermediate axis. In combination with Figure 3 and Figure 4 In short, since the retaining member 123 is elastically connected between the first connecting part 121c and the second connecting part 122c, the first connecting part 121c and the second connecting part 122c can move, or at least have a tendency to move, in a direction close to each other. Then, as shown in Figure 4 When the elastic axis is above the intermediate axis, the retaining member 123 can drive the first connecting part 121c and the second connecting part 122c to close to each other to keep the first clamping assembly 120 closed. As shown in Figure 3 When the elastic axis is below the intermediate axis, the retaining member 123 can drive the first connecting part 121c and the second connecting part 122c to close to each other to keep the first clamping assembly 120 open, facilitating the optical connection of the first joint 200 and the adapter 110. The above-mentioned elastic axis refers to Figure 3 and Figure 4 in the drawings, and the above-mentioned intermediate axis refers to Figure 3 and Figure 4 in the drawings.

[0057] Please refer to Figure 4In one embodiment, the first clamping jaw 121 comprises a first guide surface 121d, and the second clamping jaw 122 comprises a second guide surface 122d. The first guide surface 121d is arranged opposite to the second guide surface 122d. In the insertion direction of the first connector 200, the distance between the first guide surface 121d and the second guide surface 122d gradually decreases. In this way, the first connector 200 can gradually align with the corresponding position on the adapter 110 under the guidance of the first guide surface 121d and the second guide surface 122d, so as to facilitate the plug-in cooperation between the first connector 200 and the adapter 110.

[0058] Referring to Figures 2 to 4 In one embodiment, the second clamping assembly 130 is rotatably arranged on the adapter 110 to open and close. When the second clamping assembly 130 is closed, it is used to lock the second connector 300, and when the second clamping assembly 130 is opened, it is used to release the second connector 300. In this way, through the cooperation of the first clamping assembly 120 and the second clamping assembly 130, the first connector 200 and the second structure can be stably connected. When the first clamping assembly 120 and the second clamping assembly 130 are both opened, the first connector 200 and the second connector 300 can be conveniently detached from the adapter 110.

[0059] In some embodiments, the first clamping assembly 120 and the second clamping assembly 130 have the same structure. The second clamping assembly 130 is used to lock or release the second connector 300. That is, in the present embodiment, the connection structure 100 can include two identical first clamping assemblies 120 to clamp the first connector 200 and the second connector 300 respectively, so that the first connector 200 and the second connector 300 are both fixed to the adapter 110. It can be understood that sometimes the sizes of the first connector 200 and the second connector 300 are different, and the structures of the first clamping assembly 120 and the second clamping assembly 130 can be the same, the size of the first clamping assembly 120 is suitable for the first connector 200, and the size of the second clamping assembly 130 is suitable for the second connector 300.

[0060] Of course, in other embodiments, the second clamping assembly 130 can also have a structure different from that of the first clamping assembly 120. Referring to Figure 6 In one embodiment, the second clamping assembly 130 comprises a third clamping jaw 131 and a fourth clamping jaw 132, and the third clamping jaw 131 and the fourth clamping jaw 132 are both rotatably connected to the adapter 110 to release or lock the second connector 300.

[0061] In combination with Figure 7In particular, the second clamping assembly 130 further comprises a locking member 1330 and a spreading member 134. The locking member 1330 is connected with the third clamping jaw 131 and the fourth clamping jaw 132, so that the third clamping jaw 131 and the fourth clamping jaw 132 are kept in relative fixation. In this way, the third clamping jaw 131 and the fourth clamping jaw 132 are cooperated by the locking member 1330 to stably lock the second connector 300.

[0062] Please refer to Figure 6 In one embodiment, the spreading member 134 is connected with the third clamping jaw 131 and the fourth clamping jaw 132, so that the third clamping jaw 131 and the fourth clamping jaw 132 are rotated in a direction away from each other for opening the second connector 300. That is, when the third clamping jaw 131 and the fourth clamping jaw 132 lose the connection effect of the locking member 1330, the third clamping jaw 131 and the fourth clamping jaw 132 can be moved in a direction away from each other under the action of the spreading member 134 to release the second connector 300. At this time, the second connector 300 is no longer locked by the second clamping assembly 130 and can be easily separated from the adapter 110. In other words, the convenience of disassembling the second connector 300 can be improved by providing the spreading member 134.

[0063] Please refer to Figure 6 In one embodiment, the spreading member 134 comprises a first spreading part 134a, which is elastically abutted between the third clamping jaw 131 and the adapter 110 to push the third clamping jaw 131 to rotate in a direction away from the fourth clamping jaw 132. It can be understood that the third clamping jaw 131 and the fourth clamping jaw 132 are arranged on opposite sides of the adapter 110, and the adapter 110 is recessed to provide a first accommodating groove 115. One end of the first spreading part 134a extends into the first accommodating groove 115 and abuts against the bottom wall of the first accommodating groove 115, and the other end of the first spreading part 134a abuts against the third clamping jaw 131 to make the third clamping jaw 131 rotate in a direction away from the adapter 110, i.e. in a direction away from the fourth clamping jaw 132.

[0064] Please refer to Figure 6 In one embodiment, similar to the first spreading part 134a, the spreading member 134 further comprises a second spreading part 134b, which is elastically abutted between the fourth clamping jaw 132 and the adapter 110 to push the fourth clamping jaw 132 to rotate in a direction away from the third clamping jaw 131. The adapter 110 is also recessed to provide a second accommodating groove (not shown, same below). One end of the second spreading part 134b extends into the second accommodating groove and abuts against the bottom wall of the second accommodating groove, and the other end of the second spreading part 134b abuts against the fourth clamping jaw 132 to make the fourth clamping jaw 132 rotate in a direction away from the adapter 110, i.e. in a direction away from the third clamping jaw 131.

[0065] Please refer toFigure 6 In one embodiment, the adapter 110 further comprises a first blocking portion 113 and a second blocking portion 114. When the second clamping assembly 130 is opened, the first blocking portion 113 abuts against a side of the third jaw 131 away from the fourth jaw 132, and the second blocking portion 114 abuts against a side of the fourth jaw 132 away from the third jaw 131. That is, the third jaw 131 and the fourth jaw 132 can be respectively limited by the first blocking portion 113 and the second blocking portion 114, so that the positions of the third jaw 131 and the fourth jaw 132 relative to the adapter 110 are more stable, and the third jaw 131 and the fourth jaw 132 are prevented from being opened too much under the action of the opening member 134, which makes it inconvenient to lock the second joint 300 later. At the same time, the first opening portion 134a and the second opening portion 134b can also be prevented from being detached from the adapter 110.

[0066] Please continue to refer to Figure 6 In one embodiment, the adapter 110 comprises a first end 111 for connecting with the first joint 200 and a second end 112 for connecting with the second joint 300, one end of the second clamping assembly 130 is rotationally connected with the first end 111, and the other end of the second clamping assembly 130 extends to the second end 112 for clamping with the second joint 300. In this way, the second clamping assembly 130 can have a larger length extension size, so that the first blocking portion 113, the second blocking portion 114, the opening member 134, and the locking member 1330 can have sufficient space to be distributed on the adapter 110 to cooperate with the third jaw 131 and the fourth jaw 132, and the third jaw 131 and the fourth jaw 132 can also be applicable to a plurality of different joints with a larger size range. At the same time, in this way, the third jaw 131 and the fourth jaw 132 have a larger radius of rotation, and when the free ends of the third jaw 131 and the fourth jaw 132 move the same displacement, the third jaw 131 and the fourth jaw 132 only need to rotate a smaller angle, that is, the displacement variation of the third jaw 131 and the fourth jaw 132 is smaller.

[0067] Please refer to Figure 7 and Figure 8 In one embodiment, the locking member 1330 comprises a first abutting portion 1331 and a second abutting portion 1332, the first abutting portion 1331 abuts against a side of the third jaw 131 away from the fourth jaw 132, and the second abutting portion 1332 abuts against a side of the fourth jaw 132 away from the third jaw 131. In this way, the first abutting portion 1331 and the second abutting portion 1332 can prevent the third jaw 131 and the fourth jaw 132 from moving away from each other.

[0068] Please refer to Figure 8In one embodiment, the locking member 1330 further comprises a driving member 1333 and a guide rail 1334. The driving member 1333 is connected with the first abutting portion 1331 and the second abutting portion 1332 to drive the first abutting portion 1331 and the second abutting portion 1332 to move towards or away from each other. The first abutting portion 1331 and the second abutting portion 1332 are slidably arranged on the guide rail 1334, and can slide along the guide rail 1334 under the action of the driving member 1333. When the first abutting portion 1331 and the second abutting portion 1332 move towards each other, the second clamping assembly 130 can be clamped, so that the second clamping assembly 130 locks the second joint 300. When the first abutting portion 1331 and the second abutting portion 1332 move away from each other, the second clamping assembly 130 can be separated, and at this time the third clamping jaw 131 and the fourth clamping jaw 132 can be automatically opened under the action of the opening member 134, thereby facilitating the disassembly of the second joint 300.

[0069] Please refer to Figure 8 In one embodiment, the first abutting portion 1331 comprises a plurality of first abutting bodies 1331a distributed along the extending direction of the third clamping jaw 131, and each of the first abutting bodies 1331a abuts the side of the third clamping jaw 131 away from the fourth clamping jaw 132. The second abutting portion 1332 comprises a plurality of second abutting bodies 1332a distributed along the extending direction of the fourth clamping jaw 132, and each of the second abutting bodies 1332a abuts the side of the fourth clamping jaw 132 away from the third clamping jaw 131.

[0070] In some embodiments, the locking member 1330 can also be connected with the third clamping jaw 131 and the fourth clamping jaw 132 in other ways. For example, a fixing hole can be formed on each of the third clamping jaw 131 and the fourth clamping jaw 132, and the locking member 1330 can be inserted into the fixing holes on the third clamping jaw 131 and the fourth clamping jaw 132 at the same time, so that the third clamping jaw 131 and the fourth clamping jaw 132 are fixed. When the second clamping assembly 130 needs to be opened, the locking member 1330 can be pulled out of the fixing holes, and at this time the third clamping jaw 131 and the fourth clamping jaw 132 can be automatically opened under the action of the opening member 134.

[0071] In other embodiments, the locking member 1330 can be arranged on one of the third jaw 131 and the fourth jaw 132 and detachably connected with the other. For example, when the locking member 1330 is arranged on the third jaw 131, the locking member 1330 is connected with the fourth jaw 132, and the second clamping assembly 130 locks the second connector 300; when the locking member 1330 is separated from the fourth jaw 132, the second clamping assembly 130 is opened. The locking member 1330 arranged on the fourth jaw 132 is the same, and thus is not described herein. In the embodiment, the locking member 1330 is rotatably arranged on one of the third jaw 131 and the fourth jaw 132 and detachably connected with the other.

[0072] Of course, in some embodiments, the structure of the first clamping assembly 120 can also be the same as that of the second clamping assembly 130. That is, the connecting structure 100 can also include two identical second clamping assemblies 130 to clamp the first connector 200 and the second connector 300, respectively, so that the first connector 200 and the second connector 300 are both fixed with the adapter 110.

[0073] The technical features of the above embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0074] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of variations and improvements can be made, which are within the scope of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
