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 to improve the coupling efficiency of optical signals from light sources to optical fibers or from optical fibers to detectors. Lens arrays are an arrangement of multiple tiny lenses, each lens corresponding to one or more optical fibers, which can process multiple optical signals at the same time. 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 docked. The combination of MT connectors and optical lenses usually appears in optical transceiver modules, fiber couplers, and other devices that require efficient optical coupling.

[0003] At present, when connecting the optical lens on the PCB board with the MT connector, the MT connector is usually manually held and aligned with the optical lens for plugging. However, due to the small size of the optical lens and the MT connector, and the large number of optical fibers at the tail of the MT connector, manual operation is very inconvenient, and it is easy to cause the connector to be inserted crookedly and unable to align. The assembly is more difficult, requires more time and labor, and has low assembly efficiency. In addition, the staff cannot accurately control the plugging distance, resulting in the connector not being plugged in 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

[0005] The purpose of the present invention is to provide an optical device assembly structure to solve the above technical problems.

[0006] To achieve the above object, the present invention adopts the following technical solution:

[0018] Furthermore, the adjusting component includes:

[0019] The receiving seat has a movable seat slidably arranged thereon, and an adjusting rod is threadedly connected to the position of the receiving seat corresponding to the movable seat.

[0020] Furthermore, the flap is hinged to one of the positioning slides, a mounting groove is provided on the flap, the pushing mechanism is located in the mounting groove, and a reset component is also provided in the mounting groove.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-10 , an optical device assembly structure, used to connect an MT connector 1 and an optical lens 2, the optical lens 2 is mounted on a PCB board 3, comprising:

[0045] A base 4 is provided with a support base 5, and a placement groove 6 matching the PCB board 3 is provided on the support base 5;

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

[0047] The pushing mechanism 9 is disposed on the flap 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 in FIG. 1 is then shown, and then the PCB board and the optical lens 2 thereon are placed in 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 in FIG. 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 process of the flap 8 rotating and covering, the MT connector 1 is pressed down by the pushing mechanism 9 to finally align the connection position of the optical lens 2 in the vertical direction. Then the pushing mechanism 9 is moved horizontally, and the pushing mechanism 9 drives the MT connector 1 to move horizontally. At this time, the MT connector 1 moves toward the direction of the optical lens 2, and finally the MT connector 1 and the optical lens 2 are plugged and installed together, as shown in FIG. 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. This avoids the inconvenience of manual plug-in operation. The assembly structure can also greatly prevent the frequent crooked insertion and misalignment of the manual assembly, and can reduce the damage to the MT connector 1 and the optical lens 2 caused by the error. 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 to move and plug can be accurately controlled to prevent the situation of inadequate 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 comprises:

[0050] There are two positioning slides 71, which are symmetrically slidably arranged on the base 4, and a positioning groove 72 is arranged at one end of the two positioning slides 71 which are close to each other;

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

[0052] The inclined plane block 74 is disposed on the positioning slide 71 , and a magnet is also disposed inside the inclined plane block 74 , and the magnetism thereof is opposite to that of the magnet inside 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; then, 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 a direction close to each other, and finally the inclined block 74 on the positioning slide 71 is in contact with the limiting block 73, and the two positioning slides 71 are mutually adsorbed 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 rail 10 is provided on the base 4, and a slider 11 is provided at the bottom of the positioning slide 71 to be slidably connected to the linear slide rail 10. When the positioning slide 71 is moved, the positioning slide 71 moves along the linear slide rail 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 3-6Two connected adjusting components 12 are arranged on the base 4, and the limiting block 73 is connected to one of the adjusting components 12. The two adjusting components 12 are respectively used to adjust the front-back and left-right positions of the limiting block 73. The two adjusting components 12 are stacked together. For example, the upper adjusting component 12 can drive the limiting block 73 to move in the front-back direction, while the lower adjusting component 12 can drive the upper adjusting component 12 and the limiting block 73 to move in the left-right direction. Then, the cooperation of the two adjusting components 12 can make the limiting block 73 move in the front-back and left-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 application, which further improves 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 comprises:

[0057] The receiving seat 121 is slidably provided with a moving seat 122, and an adjusting rod 123 is threadedly connected to the position of the receiving seat 121 corresponding to the moving seat 122. The adjusting rod 123 is a threaded rod, and when the adjusting rod 123 is rotated, the adjusting rod 123 drives the moving seat 122 to move along its axial direction, for example, the lower adjusting rod 123 drives the moving seat 122 to move left and right, that is, the upper receiving seat 121 moves left and right, and the upper adjusting rod 123 drives the upper moving 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 hinged to one of the positioning slides 71, and a mounting groove 13 is provided on the flap 8. The push mechanism 9 is located in the mounting groove 13, and a reset component 14 is also provided in the mounting groove 13. When the flap 8 is turned over to cover the MT connector 1 and the optical lens 2, the push mechanism 9 is used to drive the MT connector 1 to move and assemble with the optical lens 2. After the assembly is completed, the reset component 14 will reset the push mechanism 9 to facilitate the next use.

[0059] In this embodiment, preferably, please refer to 1-6 and Figure 8-10 , promoting institutions 9 include:

Then, the hand push plate 91 is pushed horizontally, and the hand push plate 91 will drive the connecting plate 92, the pressing block 93 and the push column 94 to move. At this time, the push column 94 will make the MT connector 1 move horizontally, so that the assembly of the MT connector 1 and the optical lens 2 can be realized, which is simple and convenient to operate, saving time and effort. After the MT connector 1 is moved into place, the pressing block 93 will be blocked by the outer shell of the optical lens 2, which means that the MT connector 1 is moved and plugged into place, and the installation groove 13 of the flap 8 will also have a certain limiting effect, which can effectively avoid the current situation that the MT connector 1 cannot be plugged into place, and the use effect is good.

[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, and a screw rod 141 is connected to the inner thread of the mounting groove 13.

The elastic member 142 in the present application can be a spring. When in a normal state, the elastic member 142 is in a compressed state. When the hand push plate 91 is pushed to move, the elastic member 142 will be further compressed by the hand push plate 91. After the hand push plate 91 is no longer pushed, the hand push plate 91 can be reset by the reset elastic force of the elastic member 142. The elastic member 142 can be driven to move by rotating the screw rod 141, 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.

When placing the MT connector 1, the optical fiber at the tail of the MT connector 1 can be passed through the card slot 16 of the side seat 15, and the optical fiber is not shown in the figure. Then, the cover plate 17 is turned over to cover the optical fiber at the tail of the MT connector 1, which can effectively restrict it and prevent the optical fiber at the tail of the MT connector 1 from being scattered and messy. The optical fiber at the tail of the MT connector 1 can also be passed through the limiting cylinder 20, and then the limiting cylinder 20 is placed in the card slot 16, so as to more conveniently centrally restrict the optical fiber at the tail of the MT connector 1.
