Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to an optical module packaging structure and an optical module. Background Art

[0002] The optical module is mainly composed of optoelectronic devices, functional circuits and optical interfaces, including a transmitting end and a receiving end. The transmitting end converts electrical signals into optical signals. After transmitting through optical fibers, the receiving end converts the optical signals into electrical signals again. It is often inserted into the optical module jacks of optical fiber switches, optical fiber network cards, servers and other equipment for use with external optical fibers.

[0003] The commonly used optical modules on the market include a shell and a circuit board and optical components encapsulated in the shell. The shell is divided into two parts: a bottom shell and an upper cover. The bottom shell and the upper cover in traditional optical modules are mostly connected by screws. For example, an optical module packaging structure disclosed in the patent with application number 202020798057.1 adopts a traditional screw installation structure; in addition, some optical modules in the prior art are also fastened together with multiple elastic buckles arranged on the bottom shell and the upper cover. The above two common fixing structures require the use of external tools when disassembling and assembling the upper cover. The former requires a screwdriver, and the latter generally uses a sharp tool to insert into a gap to pry open the upper cover. If there are no relevant tools on site, it is not easy to disassemble and assemble.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art, thereby providing an optical module packaging structure and an optical module which are scientifically designed, can be disassembled and assembled without auxiliary tools, are simple to operate, and have strong practicality.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an optical module packaging structure, including a shell, one end of the shell is an optical fiber connection end, and the other end is an equipment connection end, the shell includes a bottom shell and an upper cover, the bottom shell is a U-shaped structure with an opening at the top, and the upper cover is a U-shaped structure with an opening at the bottom, the bottom shell includes an assembly section assembled with the upper cover and an extension section extending out of the upper cover equipment connection end, the outer sides of the two side walls of the assembly section are respectively provided with transverse grooves, the inner sides of the two side walls of the upper cover are respectively provided with transverse ridges plug-matched with the transverse grooves, the bottom wall of the extension section is connected to the bottom wall of the assembly section, and the two sides of the extension section adopt elastic side walls and are disconnected from the two side walls of the assembly section, and the transverse ridges can be completely avoided or tripped by the deformation of the two elastic side walls.

[0007] Based on the above, the elastic side wall includes a flat plate portion and a clamping foot, the flat plate portion is used to connect with the optical module interface on the device, one end of the clamping foot is in contact with the end surface of the assembly section, and the other end is connected to the flat plate portion through an inclined surface.

[0008] Based on the above, in the assembled state, the outer side of the side wall of the assembly section is flush with the outer side of the side wall of the upper cover.

[0009] Based on the above, the cross section of the transverse ridge is rectangular.

[0010] The utility model also provides an optical module, comprising the optical module packaging structure as described above, and a circuit board and an optical component packaged in the housing.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) By utilizing the structural feature of the optical module that the device connection end of the bottom shell protrudes beyond the upper cover, the bottom shell is divided into the assembly section and the extension section. By providing the transverse groove on the assembly section and the transverse ridge on the upper cover, the two can be plugged in and out transversely. By providing the elastic side wall on the extension section, the elastic side wall can be caught on the transverse ridge in a natural state to fix the two. When disassembling, the elastic side wall is pinched inward with fingers to deform it to avoid the transverse ridge. Disassembly and assembly can be achieved without the aid of auxiliary tools.

[0013] (2) By configuring the elastic side wall as a flat plate and a clamping foot, the outer side wall of the assembly section is flush with the outer side wall of the upper cover, so that its main structure is consistent with the traditional optical module and does not affect the normal connection with the optical module interface on the device.

[0014] (3) The cross section of the transverse ridge is set to be rectangular, so that the engagement between the transverse groove and the transverse ridge is more stable and not easy to disengage. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is further described in detail below through specific implementation methods. Example 1

[0022] like Figure 1-4 As shown, an optical module packaging structure includes a shell, one end of the shell is an optical fiber connection end, and the other end is a device connection end, the shell includes a bottom shell 1 and an upper cover 2, the bottom shell 1 is a U-shaped structure with an opening at the top, and the upper cover 2 is a U-shaped structure with an opening at the bottom, the bottom shell 1 includes an assembly section 11 assembled with the upper cover 2 and an extension section 12 extending out of the device connection end of the upper cover 2, the outer sides of the two side walls of the assembly section 11 are respectively provided with transverse grooves 3, the inner sides of the two side walls of the upper cover 2 are respectively provided with transverse ridges 4 plugged with the transverse grooves 3, the bottom wall of the extension section 22 is connected to the bottom wall of the assembly section 11, and the two sides of the extension section 12 adopt elastic side walls 5 and are disconnected from the two side walls of the assembly section 11.

[0023] The elastic side wall 5 specifically includes a flat plate portion 51 and a clamping foot 52. The flat plate portion 51 is used to connect with the optical module interface on the device. One end of the clamping foot 52 is in contact with the end surface of the assembly section 11, and the other end is connected to the flat plate portion 51 through an inclined surface. The deformation of the two elastic side walls 5 can completely avoid or trip the transverse convex ridge 4; and in the assembled state, the outer side of the side wall of the assembly section 11 is flush with the outer side of the side wall of the upper cover 2. This makes its main structure consistent with the traditional optical module and does not affect the normal connection with the optical module interface of the device.

[0024] Working principle:

[0025] When installing the upper cover 2, align the transverse groove 3 and the transverse ridge 4. When pushing the upper cover 2 to be inserted, the two elastic side walls 5 are compressed and deformed inward by squeezing the inclined surface of the clamping foot 52, completely avoiding the transverse ridge 4. After being inserted into place, the elastic side walls 5 recover and trip the transverse ridge 4 to achieve fixation. When disassembling, use your fingers to pinch the elastic side walls 5 inward to deform them to avoid the transverse ridge 4, and then pull out the upper cover 2.

[0026] In order to prevent the upper cover 2 from being easily separated from the bottom shell 1 , the cross section of the transverse ridge 4 is rectangular. Example 2

[0027] like Figure 5 As shown, an optical module includes the optical module packaging structure in Example 1 and a circuit board 6 and an optical component 7 packaged in the housing. The circuit board 6 and the optical component 7 adopt traditional structures.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
