Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to a packaging structure for optical modules. Background Art

[0002] Optical modules are composed of optoelectronic devices, functional circuits, and optical interfaces. Optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of an optical module is to convert electrical signals into optical signals at the transmitting end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals. In the process of producing optical modules, the optical modules need to be packaged.

[0003] After searching, an optical module packaging structure was proposed according to the Chinese utility model application number CN202122311245.4, and its invention content recorded "An optical module packaging structure of the utility model connects the lower packaging shell with the upper packaging shell, pushes the unlocking push rod, and the positioning rod enters the inner cavity of the positioning groove for positioning. At the same time, the movable rod and the positioning cross plate enter the inner cavity of the movable groove and the translation groove. Release the unlocking push rod so that the positioning cross plate enters the inner cavity of the translation groove to complete the packaging. The optical module packaging structure encapsulates the surface of the optical module body through the lower packaging shell and the upper packaging shell. The packaging process is simple and quick, and it is also convenient to disassemble the optical module body, saving maintenance time and improving practicality."

[0004] Among them, after the optical module packaging structure is completed, the unlocking push rod is easily moved by accidental touching. When the staff accidentally touches the unlocking push rod to move it to the appropriate position, the unlocking push rod will drive the positioning cross bar to move to the inside of the translation groove. When the lower packaging shell moves downward under gravity, it will separate from the upper packaging shell, causing the optical module body to fall off, affecting the packaging stability. Improvement is needed, so a packaging structure for optical modules is proposed to solve the above problem. Utility Model Content

[0007] The positioning mechanism includes multiple springs, and four positioning grooves are provided on the top of the lower packaging shell and the bottom of the upper packaging shell. The multiple springs are symmetrically fixedly connected to the opposite side of the inner wall of the positioning groove, and a positioning block is fixedly installed on the side of the multiple springs away from the inner wall of the positioning groove. A moving block is fixedly installed on the top of two of the positioning blocks, and a positioning plate is arranged between the two moving blocks.

[0008] Furthermore, the top of the lower packaging shell and the bottom of the upper packaging shell are both provided with through holes matching the optical module body.

[0009] Furthermore, the positioning block is L-shaped, and the positioning block matches the positioning groove.

[0010] Furthermore, a moving groove is provided on one side opposite to the two moving blocks, and moving blocks extending into the moving groove are fixedly mounted on both the left and right sides of the positioning plate, and the moving groove matches the moving block.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a packaging structure for an optical module includes a lower packaging shell 1, an upper packaging shell 2 is arranged on the lower packaging shell 1, an optical module body 3 is placed between the lower packaging shell 1 and the upper packaging shell 2, the top of the lower packaging shell 1 and the bottom of the upper packaging shell 2 are both provided with through holes matching the optical module body 3, and a positioning mechanism 4 is arranged on the upper packaging shell 2.

[0022] Specifically, the staff first places the optical module body 3 inside the lower packaging shell 1, then buckles the upper packaging shell 2 on the top of the lower packaging shell 1, and finally uses the positioning mechanism 4 to position the lower packaging shell 1 and the upper packaging shell 2. The positioning mechanism 4 is not easy to loosen by accidental touch, which reduces the possibility that the lower packaging shell 1 will separate from the upper packaging shell 2 when moving downward under gravity, causing the optical module body to fall off, thereby improving the packaging stability.

[0023] In this embodiment, the positioning mechanism 4 includes a plurality of springs 41, and four positioning grooves are provided on the top of the lower packaging shell 1 and the bottom of the upper packaging shell 2. The plurality of springs 41 are symmetrically fixedly connected on the opposite side of the inner side wall of the positioning groove, and a positioning block 42 is fixedly installed on the side of the inner side wall of the positioning groove away from the plurality of springs 41. The positioning block 42 is L-shaped, and the positioning block 42 matches the positioning groove. A moving block 43 is fixedly installed on the top of the two positioning blocks 42, and a positioning plate 44 is arranged between the two moving blocks 43. Moving grooves are provided on the opposite sides of the two moving blocks 43, and moving blocks extending into the moving grooves are fixedly installed on the left and right sides of the positioning plate 44, and the moving grooves match the moving blocks. The tops of the two moving blocks 43, the top of the positioning plate 44 and the top of the upper packaging shell 2 are flush, and the front and rear sides of the moving block 43, the front and rear sides of the positioning plate 44, the front and rear sides of the upper packaging shell 2 and the front and rear sides of the lower packaging shell 1 are flush.

[0024] Specifically, the staff moves the two moving blocks 43 relative to each other, and the two moving blocks 43 drive the two positioning blocks 42 to move relative to each other to compress the multiple springs 41. When the two positioning blocks 42 move to appropriate positions, the upper packaging shell 2 is buckled on the top of the lower packaging shell 1, and the two positioning blocks 42 are inserted into the interior of the lower packaging shell 1. Then, the two moving blocks 43 are moved back to back, and the two moving blocks 43 drive the two positioning blocks 42 to move back to back to stretch the multiple springs 41. When the two positioning blocks 42 move to appropriate positions, the positioning plate 44 is inserted between the two moving blocks 43, and the positioning plate 44 positions the two moving blocks 43.

[0025] In this embodiment, a plurality of docking grooves are formed on the top of the lower packaging shell 1 , and a plurality of docking rods 5 extending into the docking grooves are fixedly mounted on the bottom of the upper packaging shell 2 , and the docking grooves match the docking rods 5 .

[0026] Specifically, when the upper packaging shell 2 is buckled on the top of the lower packaging shell 1, the docking rod 5 is inserted into the interior of the docking groove, thereby increasing the packaging stability.

[0027] The working principle of the above embodiment is:

[0028] The staff moves the two moving blocks 43 relative to each other, and the two moving blocks 43 drive the two positioning blocks 42 to move relative to each other to compress the multiple springs 41. When the two positioning blocks 42 move to appropriate positions, the upper packaging shell 2 is buckled on the top of the lower packaging shell 1, the docking rod 5 is inserted into the interior of the docking groove, and the two positioning blocks 42 are inserted into the interior of the lower packaging shell 1, and then the two moving blocks 43 are moved back to back. The two moving blocks 43 drive the two positioning blocks 42 to move back to back to stretch the multiple springs 41. When the two positioning blocks 42 move to appropriate positions, the positioning plate 44 is inserted between the two moving blocks 43, and the positioning plate 44 positions the two moving blocks 43. The positioning plate 44 is not easy to loosen by accident, which reduces the possibility that the lower packaging shell 1 will separate from the upper packaging shell 2 when it moves downward due to gravity, causing the optical module body to fall off, thereby improving the packaging stability.
