[0034] Example 1

[0035] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a high-precision fiber optic coupling device with automatic alignment function. This device includes...

[0036] The coupling mechanism 100 includes a coupling device housing 110, a mating interface 120 formed on the surface of the coupling device housing 110, a connector 130 inserted into the mating interface 120, a mounting plate 140 disposed on the surface of the connector 130, a metal spring 150 fixed to the top of the connector 130, a lower latch 160 fixed to the top of the metal spring 150, and an upper latch 170 fixed inside the mating interface 120 and used in conjunction with the lower latch 160 to latch the connector 130.

[0037] The connector 130 includes a connector head 131, two guide grooves 132 symmetrically formed on the surface of the connector head 131, and an alignment arc groove 133 formed at the end of the connector head 131 for automatic alignment with the inside of the interface 120.

[0038] Two guide strips 180 are fixedly installed inside the interface 120 for positioning and inserting the connector 131 into the guide grooves 132.

[0039] The stable connection mechanism 200 includes a fine-tuning component 210 for compatible installation of different specifications of the interface 120, an anti-disengagement component 220 for improving the anti-disengagement performance of the connector 130, and a disassembly and assembly component 230 for facilitating quick disassembly and assembly of the mounting plate 140.

[0040] The fine-tuning component 210 is used to fine-tune the upper buckle 170 to accommodate connectors 130 of different specifications, which solves the problem that traditional coupling devices cannot achieve compatible connection with connectors 130 of different specifications, and improves the versatility of the device.

[0041] Specifically, the fine-tuning component 210 includes two connecting posts 211 fixed to the top of the upper buckle 170, a connecting plate 212 fixed to the top of the two connecting posts 211, and a stud 213 rotatably mounted on the top of the coupling device housing 110 for fine-tuning the position of the upper buckle 170.

[0042] The connecting plate 212 has threaded holes on its surface that are used to engage with the stud 213. The top of the stud 213 is fixedly equipped with an anti-slip button. The fine-tuning component 210 is used to fine-tune the upper buckle 170 to accommodate different specifications of connectors 130, thereby improving the versatility of the device.

[0043] Furthermore, two anti-loosening springs 214 are fixedly installed between the top of the coupling device housing 110 and the connecting plate 212, respectively sleeved on the surface of the connecting post 211. The anti-loosening springs 214 are used to prevent the upper buckle 170 from becoming loose.

[0044] The anti-loosening spring 214 is used to prevent loosening between the stud 213 and the connecting plate 212. During long-term use, wear occurs between the threaded holes on the stud 213 and the connecting plate 212, resulting in an increase in the thread gap. This increases the loosening of the stud 213 on the connecting plate 212, thereby affecting the fine adjustment accuracy of the upper buckle 170.

[0045] Preferably, the top of the upper buckle 170 is fixedly equipped with several positioning protrusions 215 for fine-tuning and limiting the upper buckle 170, and the top of the coupling device housing 110 is provided with several positioning holes for use with the positioning protrusions 215.

[0046] The positioning protrusion 215 and the positioning hole are used to limit the upper buckle 170, thereby improving the stability of the upper buckle 170 during fine adjustment.

[0047] Before inserting the connector 130 into the interface 120, the mounting plate 140 needs to be removed from the connector 130. Then, the position of the upper clip 170 is finely adjusted according to the different specifications of the connector 130. The stud 213 is rotated by the anti-slip button block. The stud 213 drives the connecting plate 212 and the two anti-loosening springs 214 to move. In turn, the anti-loosening springs 214 drive the upper clip 170 to be finely adjusted up and down to adapt to the different specifications of the connector 130.

[0048] Insert the connector 130 into the interface 120. Align the arc groove 133 with the opening of the interface 120 automatically. Align the guide groove 132 with the guide bar 180. Insert the connector 130 completely into the interface 120. Under the elastic force of the metal spring 150, the lower latch 160 engages with the upper latch 170.

[0049] In summary, by using the fine-tuning component 210 to fine-tune the upper latch 170 to accommodate connectors 130 of different specifications, the problem of incompatibility between traditional coupling devices and connectors 130 of different specifications is solved, thus improving the versatility of the device.

[0050] Example 2

[0051] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the anti-detachment component 220 includes two return springs 221, a sliding plate 222 fixed to the other end face of the return springs 221, an active rack 223 fixed to the surface of the sliding plate 222, a linkage gear 224 meshing with the active rack 223, a driven rack 225 meshing with the linkage gear 224, and a limiting plate 226 fixed to the surface of the driven rack 225 and used to block the connector 130 to prevent it from falling off.

[0052] Among them, the anti-detachment component 220 is used to prevent the connector 130 from loosening and falling off. The force generated by the loosening of the connector 130 drives the limiting plate 226 to extend out and block the connector 130. The greater the force generated by the loosening, the better the anti-detachment effect of the connector 130. Compared with the traditional snap-fit ​​connection, it has a significant improvement in vibration resistance and anti-loosening.

[0053] Specifically, side slots are provided on both sides inside the interface 120. The reset spring 221 is fixed inside the side slot, the sliding plate 222 is slidably installed inside the side slot, and the linkage gear 224 is rotatably installed inside the side slot. The linkage gear 224 is located between the driving rack 223 and the driven rack 225.

[0054] Furthermore, a pulley 227 is rotatably mounted on one end of the sliding plate 222, and the end of the mounting plate 140 is set with an inclined surface.

[0055] The pulley 227 reduces the contact friction between the end of the sliding plate 222 and the inclined surface of the mounting plate 140. When the connector 130 shows signs of loosening, the inclined surface of the mounting plate 140 will press against the pulley 227, which can sensitively extend the limiting plate 226 into the interface 120 to block the connector 130 and prevent it from loosening further and falling off.

[0056] Preferably, a storage groove is provided on the inner wall of the interface 120, and the storage groove is used to store the limiting plate 226.

[0057] The storage slot is used to store the limiting plate 226, so as to prevent the limiting plate 226 from protruding and affecting the interior of the interface 120 and thus affecting the insertion of the connector 130.

[0058] When the connector 130 becomes loose during use, it tends to detach from the interface 120. This causes the mounting plate 140 to shift slightly, resulting in the inclined surface of the mounting plate 140 pressing against the pulley 227. The pulley 227 then pushes the sliding plate 222 to move, which in turn moves the drive rack 223. The drive rack 223 then rotates the linkage gear 224, which in turn moves the driven rack 225. This causes the limiting plate 226 to extend into the interface 120 and block and limit the loose connector 130 to prevent it from falling off.

[0059] In summary, the anti-detachment component 220 is used to prevent the connector 130 from loosening and falling off. The force generated by the loosening of the connector 130 drives the limiting plate 226 to extend and block the connector 130. The greater the force generated by the loosening, the better the anti-detachment effect of the connector 130. Compared with the traditional snap-fit ​​connection, it has a significant improvement in vibration resistance and anti-loosening.

[0060] Example 3

[0061] Reference Figure 1 , Figure 2 and Figure 8 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the disassembly and assembly component 230 includes a first strip groove 231 formed on the top of the mounting plate 140, two movable rods 232 slidably installed inside the first strip groove 231, a second strip groove 233 formed inside the mounting plate 140 and communicating with the first strip groove 231, an extension rod 234 slidably installed inside the second strip groove 233 and fixedly connected to the movable rods 232, and a hollow groove 235 formed on the surface of the connector 130.

[0062] Two extension rods 234 are engaged inside the slot 235.

[0063] The mounting plate 140 can be installed and removed by the disassembly component 230. After the connector 130 is inserted into the interface 120, the mounting plate 140 is then installed on the connector 130 to avoid interfering with the insertion of the connector 130 into the interface 120, thereby improving the installation rationality of the device.

[0064] Specifically, two symmetrical slots 236 are provided inside the slot 235. A locking block 237 is fixedly installed at the end of the extension rod 234. The locking block 237 is engaged inside the slot 236. A compression spring 238 is fixedly installed between the two extension rods 234. The compression spring 238 is located inside the second strip groove 233.

[0065] The extension rod 234 can be engaged inside the empty slot 235 through the cooperation between the slot 236 and the block 237, thereby engaging the mounting plate 140 on one side of the connector 130 to facilitate the assembly and disassembly of the connector 130. The compression spring 238 is used to maintain the elastic force on the two extension rods 234, thereby making the slot 236 firmly engaged inside the block 237.

[0066] When using the mounting plate 140, it is necessary to move the two sliding plates 222 to the sides to avoid interfering with the installation of the mounting plate 140. Insert the two extension rods 234 into the empty slot 235 and push the mounting plate 140 so that the extension rods 234 move into the empty slot 235 until the locking block 237 is engaged in the slot 236, thus completing the installation of the mounting plate 140. To remove the mounting plate 140, simply press the two moving rods 232 towards the middle and move the extension rods 234 and the locking block 237 so that the locking block 237 is disengaged from the slot 236. Then, pull the mounting plate 140 out of the connector 130.
