Referring to fig. 1, fig. 1 shows an exploded view of a photoelectric conversion device according to an embodiment of the present invention, and a photoelectric conversion device 10 according to an embodiment of the present invention includes a first optical module (not shown, the same applies hereinafter), a second optical module (not shown, the same applies hereinafter), and a connection structure 100. The connection structure 100 is used for connecting the first optical module and the second optical module which are connected with each other, that is, the connection structure 100 is used for enabling the first optical module and the second optical module to be stably connected with each other, so that optical signals can be transmitted between the first optical module and the second optical module.

The first optical module comprises a first connector 200 and the second optical module comprises a second connector 300, the connection structure 100 being adapted to interface the first connector 200 and the second connector 300 with each other. The first connector 200 and the second connector 300 are connected with the connecting structure 100, and the first connector 200 and the second connector 300 can be accurately aligned and stably connected through the connecting structure 100. In other words, the first connector 200 and the second connector 300 can be stably maintained at a desired position and connected to each other by the connection structure 100, so that an optical signal can be stably transferred between the first optical module and the second optical module.

In one embodiment, the first connector 200 may specifically be an MPO connector; the second connector 300 may specifically be an MT connector. Of course, the first connector 200 and the second connector 300 may also specifically select different types of connectors according to the configuration of the optical module, which is not limited herein.

It should be understood that the connection structure 100 described in the various embodiments of the present invention is not limited to being connected between optical modules, and any two connectors may be connected to each other by the connection structure 100 described in the various embodiments without contradiction.

Referring to fig. 1, in one embodiment, the connection structure 100 includes an adapter 110 and first and second clamping assemblies 120 and 130. The first clamping assembly 120 and the second clamping assembly 130 are rotatably arranged on the adapter 110 to be respectively opened and closed, and the first clamping assembly 120 corresponds to the first connector 200 and is used for locking or unlocking the first connector 200; the second clamping assembly 130 corresponds to the second connector 300 for locking or unlocking the second connector 300.

In the above connection structure 100, the adaptor 110 is used for connecting the first joint 200 and the second joint 300, which are connected to each other, and the first clamping assembly 120 and the second clamping assembly 130 can rotate relative to the adaptor 110 to be opened and closed respectively. When the first clamping assembly 120 and the second clamping assembly 130 are both 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 kept fixed relative to the adaptor 110, and the first connector 200 and the second connector 300 can maintain stable optical connection. When the first clamping assembly 120 and/or the second clamping assembly 130 are opened, the corresponding first joint 200 and/or second joint 300 can be released relative to the adaptor 110, so that the first joint 200 and/or the second joint 300 can be conveniently detached.

Referring to fig. 2 and 3, in one embodiment, the first clamping assembly 120 includes a first clamping jaw 121, a second clamping jaw 122, and a retainer 123. The first jaw 121 and the second jaw 122 are each rotatably connected to the adapter 110. The holding member 123 is elastically coupled between the first jaw 121 and the second jaw 122, so that the first jaw 121 and the second jaw 122 are kept closed. So configured, when the first joint 200 is driven by no external force, the first clamping jaw 121 and the second clamping jaw 122 can be kept closed by the retaining member 123, so that the stability of the first clamping assembly 120 for integrally locking the first joint 200 is improved. When the first connector 200 needs to be detached, the elastic force of the retainer 123 can be actively overcome, so that the first clamping jaw 121 and the second clamping jaw 122 can move away from each other to open the first clamping assembly 120, and the first connector 200 can be conveniently detached from the adapter 110.

Of course, in other embodiments, the retainer 123 may also hold the first jaw 121 and the second jaw 122 closed in other ways, such as magnetic force, etc. For ease of understanding, the first clamping assembly 120 is still held closed in an elastic manner by the retainer 123 in each embodiment.

It should be noted that in some embodiments, the first clamping assembly 120 may include only the first clamping jaw 121 and not the second clamping jaw 122. At this time, the first clamping jaw 121 may cooperate with the adaptor 110 to lock the first connector 200 together. That is, the adaptor 110 in this embodiment is configured to cooperate with the first clamping jaw 121 to lock the first connector 200, the first clamping jaw 121 can lock the first connector 200 when rotating forward relative to the adaptor 110, and the first clamping jaw 121 can open and unlock the first connector 200 when rotating backward relative to the adaptor 110. The forward direction and the reverse direction are relatively speaking, and can be set according to actual requirements, and are not repeated here.

For ease of understanding and description, the first clamping assembly 120 includes a first clamping jaw 121 and a second clamping jaw 122. It should be understood that, in the embodiments, the corresponding structure of the adaptor 110 can be directly used to replace the second clamping jaw 122 to cooperate with the first clamping jaw 121 to lock and unlock the first connector 200 without contradiction, so that the details of the embodiments are not repeated.

Referring to fig. 4 and fig. 5 in combination with fig. 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 sequentially distributed. The first rotating portion 121b is rotationally connected with the adaptor 110, that is, the first clamping jaw 121 forms a lever structure taking the first rotating portion 121b as a fulcrum, the first limiting portion 121a and the first connecting portion 121c are respectively located at two sides of the fulcrum, and any one of the first limiting portion 121a and the first connecting portion 121c rotates to drive the other to rotate. The first connecting portion 121c is connected to the holder 123 such that the holder 123 can pull the first connecting portion 121c to rotate in a direction approaching the second jaw 122.

Referring to fig. 4, when the first connecting portion 121c rotates in a direction approaching the second clamping jaw 122, the first limiting portion 121a is used to abut against and lock the first connector 200. That is, when the retainer 123 elastically pulls the first connecting portion 121c to rotate toward the second clamping jaw 122, the elastic force can be transmitted to the first limiting portion 121a by means of a lever, so that the first limiting portion 121a elastically abuts against the first connector 200 accordingly, and the first connector 200 and the adapter 110 are kept fixed. Thus, the first clamping jaw 121 cooperates with the second clamping jaw 122 and the adaptor 110 to lock the first connector 200.

Referring to fig. 2 and 3, when the first connector 200 needs to be disassembled, the first connecting portion 121c can be driven to rotate in a direction away from the second clamping jaw 122, and the first limiting portion 121a will be separated from the first connector 200 along with the synchronous movement of the first connecting portion 121c. In this way, the first connector 200 loses the locking function of the first clamping assembly 120 and can be conveniently detached from the rotating connector 110.

In one embodiment, similar to the first clamping jaw 121, the second clamping jaw 122 includes a second limiting portion 122a, a second rotating portion 122b, and a second connecting portion 122c sequentially distributed. The second rotating portion 122b is rotatably connected to the adapter 110, and the second connecting portion 122c is connected to the holder 123.

When the second connecting portion 122c rotates in a direction approaching the first clamping jaw 121, the second limiting portion 122a is used for abutting and locking the first connector 200.

The second connection portion 122c can drive the second limiting portion 122a to be separated from the first connector 200 when rotating in a direction away from the first clamping jaw 121, so as to facilitate the disassembly of the first connector 200. Referring to fig. 3 and fig. 4, in one embodiment, an axis where the first connecting portion 121c and the second connecting portion 122c are connected is taken as an elastic axis, and an axis where the first rotating portion 121b and the second rotating portion 122b are connected is taken as an intermediate axis. The elastic axes are located on different sides of the intermediate axis when the first clamping assembly 120 is opened and closed, respectively. In short, with reference to fig. 3 and 4, since the holder 123 is elastically connected between the first connecting portion 121c and the second connecting portion 122c, the first connecting portion 121c and the second connecting portion 122c can be moved in a direction approaching each other, or at least have the above-described movement tendency. Then, as shown in fig. 4, when the elastic axis is located above the intermediate axis, the holder 123 can drive the first connecting portion 121c and the second connecting portion 122c to approach each other to keep the first clamping assembly 120 closed. As shown in fig. 3, when the elastic axis is located below the intermediate axis, the holder 123 can drive the first connecting portion 121c and the second connecting portion 122c to approach each other to keep the first clamping assembly 120 open, so that the first connector 200 is optically connected with the adapter 110. The elastic axis is referred to by the reference number K in fig. 3 and 4, and the intermediate axis is referred to by the reference number M in fig. 3 and 4.

Referring to fig. 4, in one embodiment, the first clamping jaw 121 includes a first guiding surface 121d, the second clamping jaw 122 includes a second guiding surface 122d, and the first guiding surface 121d is opposite to the second guiding surface 122 d. The distance between the first introduction surface 121d and the second introduction surface 122d gradually decreases in the insertion direction of the first joint 200. In this way, the first connector 200 can be gradually aligned with the corresponding position on the adaptor 110 under the guiding action of the first guiding surface 121d and the second guiding surface 122d, so that the first connector 200 is in plug-in fit with the adaptor 110.

Referring to fig. 2 to 4, in one embodiment, the second clamping assembly 130 is rotatably disposed on the adaptor 110 to be opened and closed. The second clamping assembly 130 is used for locking the second connector 300 when closed, and the second clamping assembly 130 is used for unlocking the second connector 300 when opened. In this manner, the first joint 200 can be securely connected to the second structure by the first clamping assembly 120 and the second clamping assembly 130 cooperating with each other. When both the first clamping assembly 120 and the second clamping assembly 130 are opened, both the first connector 200 and the second connector 300 can be conveniently detached from the connector 110.

In some embodiments, the first clamping assembly 120 is the same structure as the second clamping assembly 130. The second clamping assembly 130 is used to lock or unlock the second connector 300. That is, in the present embodiment, the connection structure 100 may 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 adaptor 110. It will be appreciated that there may be times when the first connector 200 and the second connector 300 are not the same size, and the first clamping assembly 120 and the second clamping assembly 130 may be configured to be the same, the first clamping assembly 120 is sized to fit the first connector 200, and the second clamping assembly 130 is sized to fit the second connector 300.

Of course, in other embodiments, the second clamping assembly 130 may also be configured differently from the first clamping assembly 120. Referring to fig. 6, in one embodiment, the second clamping assembly 130 includes a third clamping jaw 131 and a fourth clamping jaw 132, wherein the third clamping jaw 131 and the fourth clamping jaw 132 are rotatably connected to the adaptor 110 for releasing or locking the second connector 300.

Referring specifically to fig. 7, the second clamping assembly 130 further includes a locking member 1330 and a spreader 134. Locking member 1330 is connected to both third jaw 131 and fourth jaw 132 such that third jaw 131 and fourth jaw 132 remain relatively stationary. In this way, third jaw 131 and fourth jaw 132 cooperate via locking member 1330 to provide stable locking of second joint 300.

Referring to fig. 6, in one embodiment, a spreader 134 is coupled to both the third jaw 131 and the fourth jaw 132 to rotate the third jaw 131 and the fourth jaw 132 away from each other for opening the second joint 300. That is, when third jaw 131 and fourth jaw 132 lose the connection of locking member 1330, third jaw 131 and fourth jaw 132 can move away from each other by spreader 134 to release second joint 300. At this time, the second connector 300 is no longer subject to the locking action of the second clamping assembly 130, and can be easily separated from the adaptor 110. In other words, the convenience of the disassembly of the second joint 300 can be improved by providing the spreader 134.

With continued reference to fig. 6, in one embodiment, the spreading member 134 includes a first spreading portion 134a, and the first spreading portion 134a is elastically abutted between the third clamping jaw 131 and the adaptor 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 disposed on two opposite sides of the adaptor 110, the adaptor 110 is concavely provided with a first accommodating groove 115, one end of the first opening portion 134a extends into the first accommodating groove 115 to abut against the bottom wall of the first accommodating groove 115, and the other end of the first opening portion 134a abuts against the third clamping jaw 131, so that the third clamping jaw 131 rotates in a direction away from the adaptor 110, that is, rotates in a direction away from the fourth clamping jaw 132.

With continued reference to fig. 6, in an embodiment, similar to the first spreading portion 134a, the spreading member 134 further includes a second spreading portion 134b, and the second spreading portion 134b 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 adaptor 110 is further concavely provided with a second accommodating groove (not shown in the drawings, and the same applies below), one end of the second stretching portion 134b stretches into the second accommodating groove to be abutted with the bottom wall of the second accommodating groove, and the other end of the second stretching portion 134b is abutted with the fourth clamping jaw 132, so that the fourth clamping jaw 132 rotates in a direction away from the adaptor 110, that is, in a direction away from the third clamping jaw 131.

Referring to fig. 6 again, in one embodiment, the adaptor 110 further includes 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 clamping jaw 131 away from the fourth clamping jaw 132, and the second blocking portion 114 abuts against a side of the fourth clamping jaw 132 away from the third clamping jaw 131. That is, the first blocking portion 113 and the second blocking portion 114 can limit the third clamping jaw 131 and the fourth clamping jaw 132 respectively, so that the positions of the third clamping jaw 131 and the fourth clamping jaw 132 relative to the adaptor 110 are more stable, and the inconvenience of locking the second connector 300 after the third clamping jaw 131 and the fourth clamping jaw 132 are opened under the action of the expanding member 134 is avoided. At the same time, the first and second expanding portions 134a and 134b can be prevented from being separated from the adaptor 110.

With continued reference to fig. 6, in one embodiment, the adaptor 110 includes a first end 111 for connecting with the first connector 200 and a second end 112 for connecting with the second connector 300, one end of the second clamping assembly 130 is rotatably connected with the first end 111, and the other end of the second clamping jaw 122 extends to the second end 112 for clamping with the second connector 300. So configured, the second clamping assembly 130 can have a larger length extension, such that the first blocking portion 113, the second blocking portion 114, the spreader 134, and the locking member 1330 can have sufficient space to be distributed on the adapter 110 to cooperate with the third clamping jaw 131 and the fourth clamping jaw 132, and the third clamping jaw 131 and the fourth clamping jaw 132 can be adapted for a plurality of different joints having a larger size range span. Meanwhile, the third clamping jaw 131 and the fourth clamping jaw 132 have larger rotation radius, and when the free ends of the third clamping jaw 131 and the fourth clamping jaw 132 move by the same displacement, the third clamping jaw 131 and the fourth clamping jaw 132 only need to rotate by smaller angles, namely the displacement fluctuation of the third clamping jaw 131 and the fourth clamping jaw 132 is smaller.

Referring to fig. 7 and 8, in one embodiment, the locking member 1330 includes a first abutting portion 1331 and a second abutting portion 1332, the first abutting portion 1331 abuts against a side of the third clamping jaw 131 opposite to the fourth clamping jaw 132, and the second abutting portion 1332 abuts against a side of the fourth clamping jaw 132 opposite to the third clamping jaw 131. In this way, the first abutting portion 1331 and the second abutting portion 1332 prevent the third clamping jaw 131 and the fourth clamping jaw 132 from moving away from each other.

Referring to fig. 8, in one embodiment, the locking member 1330 further includes a driving member 1333 and a rail 1334. The driving piece 1333 is connected to both 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 in directions approaching and separating from each other. The first abutting portion 1331 and the second abutting portion 1332 are slidably provided on the guide rail 1334, and the first abutting portion 1331 and the second abutting portion 1332 are slidable along the guide rail 1334 by the driving piece 1333. The first abutting portion 1331 and the second abutting portion 1332 can clamp the second clamping assembly 130 when moving in the direction of approaching each other, so that the second clamping assembly 130 locks the second joint 300. The first abutting portion 1331 and the second abutting portion 1332 can be separated from the second clamping assembly 130 when moving in a direction away from each other, and at this time, the third clamping jaw 131 and the fourth clamping jaw 132 can be automatically opened under the action of the spreading member 134, so that the second joint 300 is convenient to detach.

Referring to fig. 8, in one embodiment, the first abutting portion 1331 includes a plurality of first abutting bodies 1331a spaced apart along the extending direction of the third clamping jaw 131, and the plurality of first abutting bodies 1331a abut against a side of the third clamping jaw 131 away from the fourth clamping jaw 132. The second abutting portion 1332 includes a plurality of second abutting bodies 1332a distributed at intervals along the extending direction of the fourth clamping jaw 132, and each of the plurality of second abutting bodies 1332a abuts against one side of the fourth clamping jaw 132 away from the third clamping jaw 131.

In some embodiments, lock 1330 may be connected to third jaw 131 and fourth jaw 132 in other ways. For example, the third clamping jaw 131 and the fourth clamping jaw 132 may be provided with fixing holes, and the locking member 1330 may be simultaneously inserted into the fixing holes on the third clamping jaw 131 and the fourth clamping jaw 132, so as to keep the third clamping jaw 131 and the fourth clamping jaw 132 fixed. When the second clamping assembly 130 needs to be opened, the locking member 1330 can be pulled out of the fixing hole, and the third clamping jaw 131 and the fourth clamping jaw 132 can be automatically opened under the action of the opening member 134.

In other embodiments, the locking member 1330 may be provided on one of the third jaw 131 and the fourth jaw 132 and detachably connected to the other. For example, when the locking member 1330 is disposed on the third jaw 131, the locking member 1330 is connected to the fourth jaw 132, and the second clamping assembly 130 locks the second connector 300; when the latch 1330 is separated from the fourth jaw 132, the second clamping assembly 130 is opened. The same applies to the locking member 1330 provided on the fourth jaw 132, and thus, a description thereof will not be repeated. In this embodiment, the locking member 1330 is rotatably disposed on one of the third clamping jaw 131 and the fourth clamping jaw 132 and is detachably engaged with the other clamping jaw.

Of course, in some embodiments, the structure of the first clamping assembly 120 may also be identical to the structure of the second clamping assembly 130. That is, the connection structure 100 may further 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 to the adaptor 110.
