Abstract
Description
Technical Field
[0001] The utility model relates to an optical communication device, in particular to an immersion protection component and an optical and electrical conversion module of an optical and electrical conversion module. Background Art
[0002] Taking an optical fiber as an example, the optical communication device has many advantages. For example, the energy loss rate is low, the speed is fast, and the reliability is good. Therefore, most of the signal propagation converts the electrical signal into an optical signal through the optical and electrical conversion module for propagation, and then uses the optical and electrical conversion module at the receiving end to convert the optical signal into an electrical signal.
[0003] The optical and electrical conversion module generates heat energy. For a general optical and electrical conversion module, its use environment is placed in a computer room with a certain air circulation indoors, and the heat conduction medium is air. In recent years, in order to cope with high-speed transmission, the optical and electrical conversion module has evolved into a liquid immersion cooling that can take away the heat energy of the heating element more effectively in terms of heat dissipation, and the heat conduction medium is liquid. However, the change of the heat conduction medium will cause the optical signal to refract, causing the optical transmission path to deviate from the ideal path and unable to transmit the signal. Summary of the Utility Model
[0004] The purpose of the utility model is to solve various problems of the existing optical and electrical conversion module, and to provide an immersion protection component and an optical and electrical conversion module of an optical and electrical conversion module.
[0005] To achieve the above and other purposes, the utility model provides an immersion protection component of an optical and electrical conversion module, including: a cover body, including a cover and a plurality of side walls surrounding the cover, the cover and the plurality of side walls form a receiving space for receiving an optical and electrical conversion component, and one of the plurality of side walls has an opening allowing the optical and electrical conversion component to extend out; a sealing member, disposed at the connection between the plurality of side walls and the circuit board and surrounding the receiving space; and at least one limiting member, protruding from the inner surface of at least one of the plurality of side walls.
[0006] Optionally, the shape of the at least one limiting member is set to protrude from the inner surface in a first direction.
[0007] Optionally, the shape of the at least one limiting member is set to protrude from the inner surface in the first direction and a second direction, and the first direction is perpendicular to the second direction.
[0008] Optionally, the shapes of a plurality of the limiting members are set to protrude from at least one of the inner surfaces in the first direction, the second direction and a third direction, 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 shapes of multiple such limiting members are respectively set to protrude from the inner surfaces of the multiple side walls in the first direction and the third direction, and the first direction is perpendicular to the third direction.
[0010] Optionally, it further includes elastic limiting members formed on both sides of the opening.
[0011] To achieve the above and other purposes, the present utility model provides an optoelectronic conversion module, including: a circuit board; an optoelectronic conversion component signal-connected to the circuit board; and the aforementioned immersion protection component, the cover body covering the optoelectronic conversion component, and the seal closely contacting the multiple side walls and the circuit board.
[0012] Thus, for the immersion protection component and the optoelectronic conversion module of the present utility model, through the seal surrounding the accommodation space, the optoelectronic conversion component is blocked from the heat-conducting medium, thereby avoiding affecting the coupling accuracy of the optical signal. The design of the limiting member can accurately control the positioning of the optoelectronic conversion component in a selected direction, and can also prevent the cover body from floating due to the colloid damping force during the setting of the seal, achieving a pre-fixing effect.

[0035] In order to fully understand the present utility model, the following specific embodiments are used in conjunction with the accompanying drawings to make a detailed description of the present utility model. Those skilled in the art can understand the purpose, features and effects of the present utility model from the content disclosed in this specification. It should be noted that the present utility model can be implemented or applied through other different specific embodiments, and various 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 utility model. In addition, the drawings of the present utility model are only simple schematic illustrations and are not drawn according to actual dimensions. The following embodiments will further detail the related technical content of the present utility model, but the disclosed content is not used to limit the claims of the present utility model. The description is as follows:
[0036] As Figure 1 and Figure 2 shown, the photoelectric conversion module 200 of the embodiment of the present utility model includes: a circuit board 4, a photoelectric conversion component 5, and an immersion protection component 100.
[0037] The photoelectric conversion component 5 is signal-connected to the circuit board 4. The photoelectric conversion component 5 generally includes at least one of a lens, an optical fiber or an optical fiber array, and a light emitting element and a light signal receiving element. The light emitting element and the light signal receiving element generally have both functions to convert an electrical signal into a light signal for transmission and convert the received light signal into an electrical signal.
[0038] The immersion protection component 100 includes: a housing 1, a sealing member 2, and at least one limiting member 3.
[0039] The cover body 1 includes a cover 11 and a plurality of side walls 12 surrounding the cover 11. The cover 11 and the plurality of side walls 12 form a receiving space S for accommodating the photoelectric conversion component 5. One of the plurality of side walls 12 has an opening 121 allowing the photoelectric conversion component 5 to protrude. In this embodiment, the cover body 1 is generally in a hexahedron structure with the opening facing downwards to cover the photoelectric conversion component 5. However, the present utility model is not limited thereto, and in other embodiments, the cover body 1 may be in other shapes.
[0040] The seal 2 is disposed at the connection between the plurality of side walls 12 and the circuit board 4 to surround the receiving space S, that is, the seal 2 is in close contact with the plurality of side walls 12 and the circuit board 4. The seal 2 is, for example, a cured glue insoluble in the heat-conducting medium and is formed by curing. When the heat-conducting medium is water, the seal 2 is preferably hydrophobic and insoluble in water; when the heat-conducting medium is oil, the seal 2 is preferably made of a material insoluble in oil. By surrounding the receiving space S where the photoelectric conversion component 5 is located with the seal 2, the photoelectric conversion component 5 is blocked from the heat-conducting medium, thus avoiding affecting 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 side walls 12. The limiting member 3 can be used to limit the position of the photoelectric conversion component 5, so as to prevent it from being affected by external forces such as vibration and assembly errors and affecting the coupling accuracy of the optical signal. The limiting member 3 can be formed on the inner surface of the side wall 12 by means of welding, die casting, injection molding or indentation.
[0042] For example, in this embodiment, the limiting member 3 can have various forms: the first limiting member 31, the second limiting member 32 and the third limiting member 33.
[0043] See Figure 2 and Figure 3 , the shape of the first limiting member 31 is set to protrude from the inner surface of the side wall 12 in the first direction (X axis in the figure) to limit the position of the photoelectric conversion component 5. When two first limiting members 31 face each other, the positioning of the photoelectric conversion component 5 on the X axis can be more precisely controlled.
[0044] Furthermore, see Figure 2 and Figure 4 , in this embodiment, the shape of the second limiting member 32 is set to protrude from the inner surface of the side wall 12 in both the first direction (X axis in the figure) and the second direction (Z axis in the figure). The first direction is perpendicular to the second direction, that is, a single limiting member is used to limit two or more directions. The shape of the second limiting member 32 is, for example, a hemisphere. However, the present utility model is not limited thereto, and it can also be set to a plurality of limiting members to limit in a plurality of directions respectively. In addition, the restriction of the degree of freedom in the Z-axis direction is beneficial for the cover body 1 not to float due to the damping force of the colloid during the process of applying glue (setting the seal 2), and to achieve a pre-fixing effect.
[0045] For example, refer to 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 side walls 12 in the first direction (X-axis in the figure) and the third direction (Y-axis in the figure) respectively, and the first direction is perpendicular to the third direction.
[0046] The quantity, position and limiting direction of each of the above-mentioned first limiting member 31, second limiting member 32 and third limiting member 33 can be selected. In a preferred embodiment, the shapes of the plurality of limiting members 3 (the first limiting member 31, the second limiting member 32 and the third limiting member 33) are set to protrude from at least one inner surface in the first direction, the second direction and the third direction, or the inner surfaces of a plurality of side walls.
[0047] However, the present invention is not limited thereto. In other embodiments, an elastic limiting member 34 is further included and is formed on both sides of the opening 121. The elastic limiting member 34 can provide limiting in the first direction, the second direction or the third direction (the third direction in this embodiment). By forming the opening 121 on the side wall 12, the two sides of the opening 121 can be processed and bent to form the elastic limiting member 34, which stores elastic potential energy and can be opposite to the third limiting member 33, and also provides limiting for the photoelectric conversion component 5.
[0048] The present invention has been disclosed in the above with preferred embodiments. However, those skilled in the art should understand that the embodiments are only used to depict the present invention and should not be construed as limiting the scope of the present invention. It should be noted that all equivalent changes and substitutions to the embodiments should be set to be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
