Description

Technical Field

[0001] The present invention relates to the technical field of optical device assembly, and more particularly to an optical device assembly structure. Background Art

[0002] In fiber-optic communication systems, optical lenses are used to focus or collimate light beams, thereby improving the coupling efficiency of optical signals from light sources to optical fibers or from optical fibers to detectors. A lens array is an arrangement of multiple tiny lenses, each lens corresponding to one or more optical fibers, which can process multiple optical signals simultaneously. The combination of MT connectors and optical lenses is a common practice in fiber-optic communication technology to optimize the efficiency of optical signal transmission. MT connectors generally refer to an efficient, high-density connection solution for multi-core optical fiber connections. The key components of MT connectors include ferrules, housings, guide pins, and springs, which ensure that multiple optical fibers can be quickly and accurately connected. The combination of MT connectors and optical lenses is often found in optical transceiver modules, fiber couplers, and other devices that require efficient optical coupling.

[0003] Currently, when connecting an optical lens on a PCB board to an MT connector, the MT connector is usually manually held and aligned with the optical lens for insertion. However, due to the small size of the optical lens and the MT connector, and the large number of optical fibers at the end of the MT connector, manual operation is very inconvenient, and it is easy for the MT connector to be inserted crookedly and misaligned. Assembly is more difficult, requires a lot of time and labor, and has low assembly efficiency. In addition, the staff cannot accurately control the insertion distance, resulting in the situation that the connector is not inserted into place, and the assembly effect is poor.

[0004] Therefore, it is necessary to provide an optical device assembly structure to solve the above technical problems. Summary of the Invention

[0026] Furthermore, the support seat is provided with two symmetrical guide blocks, and the positioning slide is also provided with an avoidance opening.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] The base 4 is provided with a support base 5, and the support base 5 is provided with a placement groove 6 that matches the PCB board 3;

[0046] The positioning mechanism 7 is provided on the base 4 and is used to position the MT connector 1; the flap 8 is connected to the positioning mechanism 7;

[0047] The pushing mechanism 9 is provided on the flip plate 8 and is used to drive the MT connector 1 to move and connect with the optical lens 2 .

[0048] When in use, first open the flap 8 on the assembly structure, and then make the positioning mechanism 7 in the open state, that is, Figure 4 The state shown, then the PCB board and the optical lens 2 thereon are placed into the placement groove 6 of the support seat 5. At this time, the PCB board can be limited by the placement groove 6, that is, the positioning of the optical lens 2 is achieved, that is, Figure 5 By adjusting the positioning mechanism 7 to the retracted state, the MT connector 1 can be placed into the reserved position on the positioning mechanism 7, so that the MT connector 1 corresponds to the plug-in position of the optical lens 2. That is, the positioning mechanism 7 will position the MT connector 1 so that the MT connector 1 can be accurately aligned with the plug-in installation position of the optical lens 2, as shown. Figure 6-7 The state shown; then the flap 8 is flipped over to cover the MT connector 1 and the optical lens 2. During the rotation of the flap 8, the pushing mechanism 9 will press the MT connector 1 downward and finally align it with the connection position of the optical lens 2 in the vertical direction. Then the pushing mechanism 9 is moved horizontally. The pushing mechanism 9 will drive the MT connector 1 to move horizontally. At this time, the MT connector 1 will move toward the direction of the optical lens 2, and finally the MT connector 1 and the optical lens 2 will be plugged and installed together, as shown. Figure 9-10 The state shown. At this point, the plug-in assembly of the MT connector 1 and the optical lens 2 is completed. This is different from the current manual assembly method of holding the MT connector 1 in one hand and the optical lens 2 in the other hand. It avoids the inconvenience of manual plug-in operation. The present assembly structure can also greatly prevent the frequent occurrence of crooked insertion and misalignment during manual assembly, and can reduce damage to the MT connector 1 and optical lens 2 caused by errors. The assembly has good protection; the assembly is simple and fast, and the assembly efficiency is high. At the same time, the pushing mechanism 9 drives the MT connector 1 to move and assemble the optical lens 2, and the distance position of the MT connector 1 can be accurately controlled to prevent the situation of improper plug-in. The assembly effect of the MT connector 1 and the optical lens 2 is good, it has high practicality, and can be widely promoted and used.

[0049] In this embodiment, preferably, please refer to Figure 1 and Figure 3-7 , the positioning mechanism 7 includes:

[0050] There are two positioning slides 71 and they are symmetrically slidably arranged on the base 4. The two positioning slides 71 are provided with positioning grooves 72 at the ends close to each other.

[0051] The limiting block 73 is provided on the base 4. Both sides of the limiting block 73 are inclined surfaces, and magnets are provided in the inclined surfaces on both sides of the limiting block 73.

[0052] The inclined surface block 74 is disposed on the positioning slide 71 , and a magnet is also disposed in the inclined surface block 74 , and the magnetism thereof is opposite to that of the magnet in the limiting block 73 .

[0053] When in use, first move the two positioning slides 71 in a direction away from each other, that is, separate the two positioning slides 71. Figure 4 state; after that, the PCB board and the optical lens 2 thereon are placed in the placement groove 6 of the support seat 5, and then the two positioning slides 71 are moved in the direction of approaching each other, and finally the inclined block 74 on the positioning slide 71 is in contact with the limiting block 73 and connected, and the two positioning slides 71 are adsorbed on each other by magnets, that is, the two positioning slides 71 can be stabilized in the state, at this time, a positioning groove is formed between the ends of the two positioning slides 71, and the MT connector 1 is placed in the two positioning grooves 72. The positioning grooves 72 support and position the MT connector 1, so that the MT connector 1 can be accurately aligned with the plug-in installation position of the optical lens 2, such as Figure 6-7 When the positioning slide 71 is moved, the inclined block 74 and the limiting block 73 are separated.

[0054] In this embodiment, preferably, please refer to Figure 1 and Figure 3-6 A linear slide 10 is provided on the base 4, and a slider 11 is provided at the bottom of the positioning slide 71 in sliding connection with the linear slide 10. When the positioning slide 71 is moved, the positioning slide 71 moves along the linear slide 10 through the slider 11, which can improve the movement stability and smoothness of the positioning slide 71.

[0055] In this embodiment, preferably, please refer to Figure 1 and Figure 3-6The base 4 is provided with two connected adjustment components 12, and the limiting block 73 is connected to one of the adjustment components 12. The two adjustment components 12 are respectively used to adjust the front-to-back and left-to-right positions of the limiting block 73. The two adjustment components 12 are stacked together. For example, the upper adjustment component 12 can drive the limiting block 73 to move in the front-to-back direction, while the lower adjustment component 12 can drive the upper adjustment component 12 and the limiting block 73 to move in the left-to-right direction. Thus, through the cooperation of the two adjustment components 12, the limiting block 73 can be displaced in the front-to-back and left-to-right directions. By adjusting the left and right positions of the limiting block 73, the left and right positions of the inclined plane block 74 can be changed; and after adjusting the front and rear positions of the limiting block 73, the contact position between the inclined plane block 74 and the limiting block 73 will change accordingly. For example, when the limiting block 73 moves backward and the inclined plane block 74 contacts the limiting block 73, the distance between the two inclined plane blocks 74 and the positioning slide 71 will become smaller, and vice versa. The distance between the two positioning slides 71 can be changed, so that the assembly requirements of MT connectors 1 and optical lenses 2 of different specifications can be adapted by adjusting the position of the positioning slide 71. The device has strong flexibility and a wide range of applications, further improving the use effect of the device.

[0056] In this embodiment, preferably, please refer to FIG. Figure 1 and Figure 3-6 , the adjusting component 12 includes:

[0057] The receiving seat 121 has a movable seat 122 slidably mounted thereon. An adjusting rod 123 is threadedly connected to the receiving seat 121 at a position corresponding to the movable seat 122. The adjusting rod 123 is a threaded rod. When the adjusting rod 123 is rotated, the adjusting rod 123 drives the movable seat 122 to move along its axial direction. For example, the lower adjusting rod 123 drives the movable seat 122 to move left and right, which in turn causes the upper receiving seat 121 to move left and right, while the upper adjusting rod 123 drives the upper movable seat 122 to move forward and backward.

[0058] In this embodiment, preferably, please refer to Figure 1-6 and Figure 8-10 The flap 8 is hingedly connected to one of the positioning slides 71. A mounting slot 13 is defined on the flap 8. The push mechanism 9 is located within the mounting slot 13. A reset assembly 14 is also located within the mounting slot 13. After the flap 8 is flipped over to cover the MT connector 1 and the optical lens 2, the push mechanism 9 is used to move the MT connector 1 and assemble it with the optical lens 2. After assembly is complete, the reset assembly 14 resets the push mechanism 9, facilitating the next use.

[0059] In this embodiment, preferably, please refer to 1-6 and Figure 8-10 , the driving agency 9 includes:

[0060] A hand push plate 91 is slidably connected to the mounting groove 13, and a connecting plate 92 is provided on the hand push plate 91;

[0061] There are multiple pressing blocks 93 and push pins 94 , which are arranged at one end of the connecting plate 92 .

[0062] When the flap 8 is flipped over so that it covers the MT connector 1 and the optical lens 2, the pressure block 93 on the connecting plate 92 gradually presses the MT connector 1 downward, eventually aligning it vertically with the connection position of the optical lens 2. The push plate 91 is then pushed horizontally, which in turn drives the connecting plate 92, the pressure block 93, and the push post 94 to move. The push post 94 then causes the MT connector 1 to move horizontally, thus enabling the assembly of the MT connector 1 and the optical lens 2. This is a simple and convenient operation that saves time and effort. Once the MT connector 1 is in place, the pressure block 93 is blocked by the outer shell of the optical lens 2, indicating that the MT connector 1 has been properly inserted. The mounting groove 13 of the flap 8 also provides a certain limiting effect, effectively preventing the current situation where the MT connector 1 cannot be properly inserted, resulting in a good user experience.

[0063] In this embodiment, preferably, please refer to FIG. Figure 1-3 The reset assembly 14 includes a threaded groove opened on one side of the mounting groove 13. The mounting groove 13 is internally threaded with a screw 141. An elastic member 142 is provided at one end of the screw 141. One end of the elastic member 142 contacts one side of the hand push plate 91. The elastic member 142 in the present application can be a spring. When the normal state is in a compressed state, the elastic member 142 is further compressed by the hand push plate 91 when the hand push plate 91 is pushed. When the hand push plate 91 is no longer pushed, the reset elastic force of the elastic member 142 can drive the hand push plate 91 to reset. By rotating the screw 141, the elastic member 142 is driven to move, so that the distance between the elastic member 142 and the hand push plate 91 can be adjusted, that is, the restoring force and working stroke of the elastic member 142 can be changed, which can be modified according to actual needs.

[0064] In this embodiment, preferably, please refer to FIG. Figure 1 and Figure 3-7 , further comprising a side seat 15 disposed on the base 4, with a slot 16 defined therein. A cover plate 17 is hingedly connected to the side seat 15, with magnets of opposite magnetic properties disposed on the end face of the cover plate 17 and the upper end of the side seat 15. When placing the MT connector 1, the optical fiber at the end of the MT connector 1 can be passed through the slot 16 of the side seat 15 (the optical fiber is not shown in the figure). The cover plate 17 can then be flipped over to cover the optical fiber at the end of the MT connector 1, effectively confining it and preventing the optical fiber at the end of the MT connector 1 from being scattered and disordered. The optical fiber at the end of the MT connector 1 can also be passed through a confinement cylinder 20, which is then placed within the slot 16, thereby more conveniently confining the optical fiber at the end of the MT connector 1.

[0065] In this embodiment, preferably, please refer to FIG. Figure 1 、 Figure 3-4 and Figure 6-9 The support base 5 is provided with two symmetrical guide blocks 18, and the positioning slide 71 is also provided with an avoidance opening 19. The two guide blocks 18 can guide the optical fiber at the end of the MT connector 1, and the avoidance opening 19 of the positioning slide 71 can avoid the optical lens 2 to prevent interference.
