Description

Technical Field

[0001] This utility model relates to the field of object support technology, and in particular to a small optical module support device. Background Technology

[0002] With the rapid development of 5G networks, data centers, and high-speed fiber optic communications, optical modules, as core components of optical communication systems, are becoming increasingly important. The continuous upgrading and expansion of optical communication systems are leading to increasingly higher performance requirements for optical modules. Under current development trends, optical modules are widely used in various fields, such as high-speed data transmission in data centers, 5G network base station construction, and long-distance transmission in high-speed fiber optic communications. These application scenarios place higher demands on the performance of optical modules, requiring not only high-speed and stable signal transmission capabilities but also adaptability to different working environments, such as mechanical vibration and shock in industrial environments. Simultaneously, with the increasing integration of equipment, there are also requirements for smaller optical module sizes to meet space-saving needs.

[0003] In traditional optical module technology, various techniques are employed to meet diverse needs. To address miniaturization requirements, optical modules are evolving towards compact packages such as SFP-DD, QSFP-DD, and SFF, typically achieving size reduction through high-precision PCB design, silicon photonics integration technology, and COB processes. For shock-resistant design, structural rigidity is optimized, employing low-stress lens fixing, elastic material buffering, and vibration-resistant fiber optic interfaces to ensure optical path alignment accuracy remains even under vibration. For the circuit board connection structure of small optical modules, rigid-flex PCB technology is frequently used.

[0004] However, the current small optical module circuit board connection structure uses a rigid-flex board process, which is a composite material that combines multiple layers of rigid and flexible boards. This process is difficult and costly to manufacture. Utility Model Content

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] according to Figure 1-4 This utility model provides a small optical module bracket device, including: a base 1, an optical transceiver assembly 2, a first circuit board 3, a second circuit board 4, and a cover 5.

[0022] The base 1 includes: a placement slot 11 and a connection port 12; an optical transceiver assembly 2 is disposed on the placement slot 11; one end of the optical transceiver assembly 2 extends into the connection port 12; a first elastic plate 21 is provided on the side of the optical transceiver assembly 2 away from the connection port 12; the first elastic plate 21 is in contact with a first circuit board 3; a second elastic plate 31 is provided on one side of the first circuit board 3; the first elastic plate 21 and the second elastic plate 31 are wavy; the second elastic plate 31 matches the first elastic plate 21; the second circuit board 4 is in contact with the second elastic plate 31; and the cover 5 matches the base 1.

[0023] When assembling this utility model, the optical transceiver component 2 is fixedly mounted on the placement slot 11 with one end extending into the connection port 12. A first elastic plate 21 is located on the side of the optical transceiver component 2 away from the connection port 12, contacting the first circuit board 3 to provide an electrical connection between the optical transceiver component 2 and the first circuit board 3. A second elastic plate 31 is located on one side of the first circuit board 3, matching the wavy first elastic plate 21. The two elastic plates are manually bent to match, and then they automatically reset, allowing the two wavy elastic plates to fit together. Simultaneously, the second elastic plate 31 connects to the second circuit board 4, providing an electrical connection between the first circuit board 3 and the second circuit board 4. This ensures that the optical transceiver component 2, the first circuit board 3, and the second circuit board 4 are sequentially connected, enabling the electrical components to communicate. After assembling these components, the components on the base 1 are covered by a cover 5 to prevent damage from external factors. This utility model achieves this by using the cooperation between the various structures, fixing them together without the need for a rigid-flexible bonding plate. The cover 5 provides overall fixation, and the elastic plates also provide a certain buffering capacity between the structures, improving the overall structure's shock resistance.

[0024] The base 1 has a slot 13 on its top; protrusions 131 are provided on both sides of the slot 13; one end of the first circuit board 3 extends into the slot 13. The base 1 has a connecting block 14 on the side of the placement groove 11 away from the connection port 12; two connecting blocks 14 are positioned opposite each other on both sides of the placement groove 11; an inclined block 141 is provided on the side of the two connecting blocks 14 that is close to each other; an inclined groove 1411 is formed on the side of the two inclined blocks 141 that is away from the placement groove 11; the two inclined grooves 1411 are inclined downwards from the side away from each other to the other side. It also includes: a bracket 7; a limiting groove 71 is formed on one side of the bracket 7, and a limiting plate 72 is provided on the other side; the limiting groove 71 matches the protrusion 131; a limiting opening 142 is formed on the side of the connecting blocks 14 that is away from each other; the limiting plate 72 matches the limiting opening 142. It also includes: a pin header 6; the pin header 6 is connected to the second circuit board 4; positioning grooves 61 are formed on both sides of the pin header 6; the positioning grooves 61 match the inclined grooves 1411. A groove 721 is provided on one side of the limiting plate 72; the groove 721 matches the side of the first circuit board 3 near the first elastic plate 21.

[0025] The base 1 has a slot 13 and a protrusion 131 on its top, so that one end of the first circuit board 3 extends into the slot 13 and both sides are limited by the protrusion 131. The connecting block 14 has an inclined groove 1411. The positioning groove 61 of the pin header 6 matches the inclined groove 1411, so that the positioning groove 61 can move closer to the placement groove 11 and is positioned between the two inclined grooves 1411. When the pin header 6 continues to move, the outer side of the positioning groove 61 will abut against the side wall of the inclined groove 1411 and will be difficult to move further. The second circuit board 4 is connected to the pin header 6, so that the second circuit board 4 is also limited. The limiting groove 71 of the bracket 7 matches the protrusion 131, so that the limiting groove 71 is fitted onto the protrusion 131 for limiting. At the same time, the limiting plate 72 on one side of the bracket 7 can also extend into the limiting port 142 for limiting. The limiting plate 72 also has a groove 721, which allows one side of the first circuit board 3 to extend into it. The first circuit board 3 can be inserted into the groove 721 first, and then the bracket 7 and the first circuit board 3 are placed on the base 1, so that the first circuit board 3 extends into the slot 13. The limiting groove 71 of the bracket 7 is fitted onto the protrusion 131. At this time, the first circuit board 3 is limited by the base 1 and the bracket 7 at the same time, so that it is difficult to move further, thus completing the fixation. Then, by fitting the cover 5 onto the base 1, the bracket 7 is limited on the side away from the first circuit board 3, so that the bracket 7 is fixed. The positioning groove 61 of the pin header 6 is also limited on the side away from the placement groove 11 by the cover 5, so that the pin header 6 and the second circuit board 4 are fixed together, thus further fixing the above-mentioned structures and enhancing the stability of the overall structure.

[0026] The cover 5 includes: a fixing groove 51; a protrusion 131 that can extend into the fixing groove 51; fastening plates 52 are provided on both sides of the bottom of the cover 5; fastening grooves 15 that match the fastening plates 52 are opened on both sides of the bottom of the base 1; a positioning plate 53 is provided on one side of the fastening plate 52 of the cover 5; a positioning groove 16 that matches the positioning plate 53 is opened on one side of the fastening groove 15 of the base 1. The cover 5 is elastic to facilitate its fit with the base 1.

[0027] When the cover 5 is fixed on the base 1, the protrusion 131 extends into the fixing groove 51 to limit the top of the cover 5. The bottom fastening plate 52 can be bent first, and when it reaches the fastening groove 15, it is released and automatically returns to its original position to cooperate with the fastening groove 15 to limit the bottom of the cover 5. A corresponding positioning plate 53 and positioning groove 16 are also provided, so that the positioning plate 53 can be bent to a certain extent, then released to return to its original position and fit with the positioning groove 16 to limit the position, further improving the stability between the cover 5 and the base 1, thus improving the overall stability of this utility model.

[0028] In summary, this utility model, through the cooperation between its various structures, can fix them together without the need for a rigid-soft bonding plate. The cover also secures the whole structure, while the elastic soft plate provides a certain buffering capacity between the various structures, thereby improving the overall seismic resistance of the structure.
