Description

Technical Field

[0001] This invention relates to an optical communication device, and more particularly to an immersion protection component for a photoelectric conversion module and the photoelectric conversion module itself. Background Technology

[0002] Optical communication devices, taking optical fiber as an example, have many advantages, such as low energy loss, high speed, and high reliability. Therefore, signal propagation mostly relies on photoelectric conversion modules to convert electrical signals into optical signals for transmission, and at the receiving end, photoelectric conversion modules are used again to convert the optical signals back into electrical signals.

[0003] Photoelectric conversion modules generate heat. Typically, these modules are placed in well-ventilated indoor computer rooms, using air as the heat transfer medium. In recent years, to meet the demands of high-speed transmission, photoelectric conversion modules have evolved to utilize liquid immersion cooling, which is more effective at removing heat from the heat-generating components. However, this change in the heat transfer medium can cause light refraction, deviating the light transmission path from the ideal path and preventing signal transmission. Summary of the Invention

[0004] The purpose of this invention is to solve various problems of existing photoelectric conversion modules and to propose an immersion protection component and a photoelectric conversion module.

[0005] To achieve the above and other objectives, the present invention provides an immersion protection assembly for a photoelectric conversion module, comprising: a cover, including a cover and a plurality of sidewalls surrounding the cover, the cover and the plurality of sidewalls forming an accommodating space for accommodating the photoelectric conversion module, one of the plurality of sidewalls having an opening allowing the photoelectric conversion module to extend out; a sealing member disposed at the connection between the plurality of sidewalls and a circuit board and surrounding the accommodating space; and at least one limiting member protruding from the inner surface of at least one of the plurality of sidewalls.

[0006] Optionally, the shape of the at least one limiting member is configured to protrude from the inner surface in a first direction.

[0007] Optionally, the shape of the at least one limiting member is configured to protrude from the inner surface in the first direction and the second direction, wherein the first direction is perpendicular to the second direction.

[0008] Optionally, the shape of the plurality of limiting members is configured to protrude upward from at least one of the inner surfaces in the first direction, the second direction, and the third direction, wherein the first direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction and the second direction.

[0009] Optionally, the shape of the plurality of limiting members is configured to protrude from the inner surface of the plurality of sidewalls in the first direction and the third direction, respectively, with the first direction being perpendicular to the third direction.

[0010] Optionally, it may also include elastic limiting members formed on both sides of the opening.

[0011] To achieve the above and other objectives, the present invention provides a photoelectric conversion module, comprising: a circuit board; a photoelectric conversion component, signal connected to the circuit board; and the aforementioned immersion protection component, wherein the cover covers the photoelectric conversion component, and the seal is tightly attached to the plurality of sidewalls and the circuit board.

[0012] Therefore, the immersion protection component and photoelectric conversion module of the present invention, through the sealing member surrounding the accommodating space, isolate the photoelectric conversion component from the heat-conducting medium, thereby avoiding affecting the coupling accuracy of the optical signal. The design of the limiting member can precisely control the positioning of the photoelectric conversion component in a selected direction, and also prevent the cover from floating due to the damping force of the adhesive during the installation of the sealing member, thus achieving a pre-fixing effect.

[0035] To fully understand the present invention, the following specific embodiments, in conjunction with the accompanying drawings, will provide a detailed description. Those skilled in the art can understand the purpose, features, and effects of the present invention from the content disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the inventive point of the present invention. Furthermore, the accompanying drawings are for simple illustrative purposes only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the claims of the present invention. The following explanation is provided:

[0036] like Figure 1 and Figure 2 As shown, the photoelectric conversion module 200 of this embodiment includes: a circuit board 4, a photoelectric conversion component 5, and an immersion protection component 100.

[0037] The photoelectric conversion component 5 is connected to the signal connection circuit board 4. The photoelectric conversion component 5 typically includes at least one of a lens, an optical fiber or optical fiber array, and an optical emitting element and an optical signal receiving element. The optical emitting element and the optical signal receiving element are usually combined to convert electrical signals into optical signals for transmission and to convert received optical signals back into electrical signals.

[0038] The immersion protection assembly 100 includes: a cover 1, a seal 2, and at least one limiting member 3.

[0039] The cover 1 includes a cover 11 and a plurality of sidewalls 12 surrounding the cover 11, the cover 11 and the plurality of sidewalls 12 forming an accommodating space S for receiving the photoelectric conversion component 5. One of the plurality of sidewalls 12 has an opening 121 that allows the photoelectric conversion component 5 to extend out. In this embodiment, the cover 1 is generally hexahedral in shape with the opening facing downward to cover the photoelectric conversion component 5. However, the invention is not limited thereto, and in other embodiments, the cover 1 may have other shapes.

[0040] The seal 2 is disposed at the connection points between the multiple sidewalls 12 and the circuit board 4, surrounding the accommodating space S, meaning the seal 2 is tightly fitted to the multiple sidewalls 12 and the circuit board 4. The seal 2 is, for example, a curable adhesive insoluble in the thermally conductive medium, which is cured. When the thermally conductive medium is water, the seal 2 is preferably hydrophobic and insoluble in water; when the thermally conductive medium is oil, the seal 2 is preferably made of a material insoluble in oil. By surrounding the accommodating space S where the photoelectric conversion component 5 is located, the seal 2 isolates the photoelectric conversion component 5 from the thermally conductive medium, thus avoiding any impact on the coupling accuracy of the optical signal.

[0041] At least one limiting member 3 protrudes from the inner surface of at least one of the plurality of sidewalls 12. The limiting member 3 can be used to limit the photoelectric conversion component 5, so as to prevent the coupling accuracy of the optical signal from being affected by external forces such as vibration and assembly errors. The limiting member 3 can be formed on the inner surface of the sidewall 12 by means of welding, molding, injection molding or denting.

[0042] For example, in this embodiment, the limiting member 3 can have multiple forms: a first limiting member 31, a second limiting member 32, and a third limiting member 33.

[0043] See Figure 2 and Figure 3 The first limiting member 31 is shaped to protrude from the inner surface of the sidewall 12 in the first direction (X-axis in the figure) to limit the position of the photoelectric conversion component 5. When the two first limiting members 31 are opposite each other, the positioning of the photoelectric conversion component 5 on the X-axis can be more precisely controlled.

[0044] Further, see Figure 2 and Figure 4 In this embodiment, the second limiting member 32 is shaped to protrude from the inner surface of the sidewall 12 in both the first direction (X-axis in the figure) and the second direction (Z-axis in the figure), with the first direction perpendicular to the second direction. This means that a single limiting member limits two or more directions. The shape of the second limiting member 32 is, for example, a hemisphere. However, the invention is not limited to this; multiple limiting members can be configured to limit movement in multiple directions respectively. Furthermore, the restriction of freedom in the Z-axis direction helps prevent the cover 1 from floating due to the damping force of the adhesive during the application of the sealant 2, thus achieving a pre-fixing effect.

[0045] For example, see Figure 2 and Figure 5 The first limiting member 31 and the third limiting member 33 protrude from the inner surfaces of the plurality of sidewalls 12 in the first direction (X-axis in the figure) and the third direction (Y-axis in the figure), respectively, with the first direction being perpendicular to the third direction.

[0046] The quantity, position, and limiting direction of the first limiting member 31, the second limiting member 32, and the third limiting member 33 described above are optional. In a preferred embodiment, the shape of the plurality of limiting members 3 (first limiting member 31, second limiting member 32, and third limiting member 33) is configured to protrude from at least one inner surface in a first direction, a second direction, and a third direction, or may be the inner surface of a plurality of sidewalls.

[0047] However, the present invention is not limited thereto. In other embodiments, it also includes elastic limiting members 34 formed on both sides of the opening 121. The elastic limiting members 34 can provide limiting in a first direction, a second direction, or a third direction (in this embodiment, it is the third direction). The opening 121 is formed by the side wall 12, and the two sides of the opening 121 can be processed and bent to form the elastic limiting members 34, which store elastic potential energy and can be opposite to the third limiting member 33, thus also providing limiting for the photoelectric conversion component 5.

[0048] The present invention has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that the embodiments are for illustrative purposes only and should not be construed as limiting the scope of the invention. It should be noted that all variations and substitutions equivalent to the described embodiments should be included within the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
