To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0038] The following is combined with Figures 1-10 This invention describes the optical module structure and device provided by this utility model.

[0039] Traditional optical modules are relatively large, which is not conducive to the installation and development of small products. For further details, please refer to... Figure 9 In existing technologies, optical modules are fixed by pressing together upper and lower covers, with the circuit board installed in the space formed by the combined upper and lower covers. While this provides good heat dissipation, it also results in a large overall structural size. To address the problems of existing technologies, this utility model provides an optical module structure, including a mounting shell 1, an optical signal transceiver 2, and a circuit board 3.

[0040] Please see Figure 1 and Figure 2 The mounting housing 1 includes at least a detachably connected first housing 11 and a second housing 12. The first housing 11 has a first mounting groove 111, and the second housing 12 has a second mounting groove 121. An optical transceiver 2 is disposed in the first mounting groove 111, and a circuit board 3 is disposed in the second mounting groove 121 and opposite to the optical transceiver 2. The bottom wall of the second mounting groove 121 extends beyond the mounting surface of the optical transceiver 2 and is parallel to it. During installation, the circuit board 3 is inserted into the second mounting groove 121, and the optical transceiver 2 is parallel to the circuit board 3. Figure 9 The installation method in the conventional structure can effectively reduce the length of the optical module structure. It should be noted that the mounting shell 1 may also include a third shell or a fourth shell. Multiple shells only need to be able to be combined to form a complete mounting shell 1, and include the first mounting groove 111 and the second mounting groove 121 arranged opposite to each other. This utility model does not limit this.

[0041] Figure 4 In this configuration, the optical transceiver 2 is positioned close to the inner side below the first housing 11, against the bottom wall of the first mounting groove 111, maintaining a minimum mounting gap and minimizing the overall length of the optical module structure. Further details can be found in the following section. Figure 4The lower end of the circuit board 3 protrudes from the second housing 4, which is used to connect with the PCB board 5 of the device to perform the conversion of electrical signals and optical signals.

[0042] Furthermore, the end of circuit board 3 has a soldering section 31, which is used to solder to the PCB board 5 of the device for converting electrical signals to optical signals. It should be noted that... (See also...) Figure 10 In traditional technology, one end of the optical module structure connects to an optical signal connector, while the other end typically connects to the device's PCB board 5 via a connector. This connection method is relatively complex, and the connector also occupies some space, resulting in a larger footprint for the entire device. Please refer to [link / reference]. Figure 6 This utility model eliminates the connector and directly welds the circuit board 3 of the optical signal transceiver 2 to the PCB board 5 of the device vertically. Compared with the horizontal connection through the connector in the traditional technology, it can effectively reduce the volume of the optical module structure and is conducive to the miniaturization of optical module products.

[0043] Since circuit board 3 is a precision product, it is necessary to support the optical transceiver 2 to prevent damage to circuit board 3 caused by pressing it against the transceiver 2. In an optional embodiment, a support plate can be placed between the two to support the optical transceiver 2; however, the placement of the support plate may affect the installation and disassembly of both components. Therefore, in another optional embodiment, please refer to... Figures 2-4 The second housing 12 has two first sidewalls 123 arranged opposite each other in the width direction. Each first sidewall 123 has a support block 125 on the side near the second mounting groove 121, and the end face of the support block 125 abuts against the bottom wall of the optical transceiver 2. It is understood that the support block 125 protrudes from the side of the first sidewall 123 to support the optical transceiver 2. Multiple support blocks 125 can be provided on each first sidewall 123, and the lengths of the multiple support blocks 125 can be the same or different. Similarly, one or more support blocks 125 can also be provided on the other two sidewalls of the second housing 12, thus providing support for the circumference of the optical transceiver 2 and making the support effect more stable.

[0044] Furthermore, to ensure the stability of the support, the second housing 12 includes a base plate 124, with two first sidewalls 123 both located on the base plate 124. The end of the support block 125 furthest from the optical signal transceiver 2 is connected to the base plate 124. It is understood that the support block 125 is connected to the base plate 124 at one end and to the first sidewall 123 on the other, fitting snugly against the first sidewall 123 for more stable support. This design also allows the support block 125 to avoid protruding too much from the first sidewall 123, thus preventing interference with the installation of the circuit board 3. Additionally, a portion of the end of the first sidewall 123 can be directly excavated to serve as the support block 125, simplifying the manufacturing process of the second housing 12.

[0045] Please see Figure 1 and Figure 5 The optical transceiver 2 includes a fixing part 22 and an optical transceiver module 21 mounted on the fixing part 22. The bottom wall of the fixing part 22 abuts against each support block 125. The fixing part 22 can fix the optical transceiver module 21 in place. In addition, the abutment between the fixing part 22 and the support block 125 prevents damage to the optical transceiver module 21. It should be noted that the shapes of the first mounting groove 111 and the second mounting groove 121 should be adapted to the optical transceiver module 21 and the circuit board 3. This can limit the horizontal or vertical displacement of both, and in particular, it can cover the optical transceiver module 21 or the circuit board 3 to prevent bumps and knocks.

[0046] Further, please refer to Figure 5 The fixing part 22 can be plate-shaped or block-shaped, extending along the width direction of the mounting shell 1. Two positioning slots 221 are provided on the fixing part 22. Two optical signal transceiver modules 21 are included, each of which is engaged in its corresponding positioning slot 221. This arrangement physically isolates the two optical signal transceiver modules 21, preventing them from colliding. It also improves the strength and deformation resistance of the mounting shell 1.

[0047] Furthermore, a thermal pad 4 is provided between the circuit board 3 and the inner wall of the second housing 12. The thermal pad 4 can fill the large gap between the circuit board 3 and the second housing 12 (eliminating the air insulation layer), so that heat can be quickly dissipated from the second housing 12.

[0048] Please see Figure 1 , Figure 6 and Figure 7 In the technical solution provided by this utility model, the welding section 31 needs to be welded to the circuit board 3 to ensure the stability of the connection between the two. Specifically, the first housing 11 is provided with a first mounting hole 112, and a connecting bolt 113 is provided on the first mounting hole 112. The connecting bolt 113 can be used to connect the PCB board 5 and the first housing 11, improving the stability of the connection between the device and the optical module structure. On the other hand, the connecting bolt 113 is also easy to disassemble. In an optional embodiment, the connecting bolt 113 can be set as a bolt. As mentioned above, the first housing 11 and the second housing 12 are detachably connected, and the two can also be connected by a bolt 122 threaded connection, which can be referred to Figure 2 The second housing 12 has holes for inserting bolts 122. A threaded sleeve 114 is provided on the inner side of the first housing 11. After the bolt 122 passes through the second housing 12, it is threaded to the threaded sleeve 114 to detachably connect the first housing 11 and the second housing 12. Of course, in other optional embodiments, the first housing 11 and the second housing 12 can also be snap-fitted or glued together, and this utility model does not limit this.

[0049] Based on the above-mentioned optical module structure, this utility model also provides a device, including a PCB board 5 and an optical module structure, wherein the circuit board 3 of the optical module structure is vertically soldered to the PCB board 5.

[0050] This utility model provides two welding methods for welding section 31. Please refer to [link / reference]. Figure 7 The PCB board 5 has a socket 51, and the soldering section 31 is vertically inserted into the socket 51 and soldered to the PCB board 5. This plug-in soldering replaces the traditional connector, reducing the interface thickness by 2-3mm (typical value) and contributing to the core miniaturization advantage. Please refer to... Figure 8 In another embodiment, the PCB board 5 has multiple solder holes 52, and the soldering section 31 includes multiple pins 32, each pin 32 being vertically inserted into the corresponding solder hole 52 and soldered to the PCB board 5. It should be noted that the solder holes 52 can be arranged in a straight line to accommodate elongated circuit boards 3, or they can be arranged in a matrix to improve the reliability of high-density solder joints. Since the main improvement of the device lies in the connection method between the PCB board 5 and the circuit board 3, other structural details of the device will not be elaborated upon.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
