Description

Technical Field

[0001] This utility model relates to an ultra-small connector for a liquid cooling heat dissipation mechanism of an optical module. Background Technology

[0002] An optical module (OPM) is an integrated module used for photoelectric conversion, which can convert optical signals into electrical signals or vice versa, playing a vital role in the field of optical communication. Since optical modules are mostly in operation, heat dissipation is required at the chip level. Therefore, an increasing number of optical modules utilize liquid cooling to achieve the desired chip temperature reduction.

[0003] Currently, when using liquid cooling to dissipate heat from optical modules, ultra-small connectors are required to connect the coolant piping of the liquid cooling system to the cooling circuit inside the optical module. To meet the miniaturization requirements of these connectors, their components also need to be ultra-miniaturized. However, due to manufacturing limitations, some components cannot be miniaturized, and subsequent assembly operations are cumbersome and difficult, hindering production efficiency. Therefore, it is necessary to design an ultra-miniature connector for the liquid cooling mechanism of optical modules to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an ultra-small connector for liquid cooling heat dissipation mechanisms of optical modules. It has a reasonable structure, is easy to manufacture and assemble, has high production efficiency, and promotes the application of connectors in the field of liquid cooling of optical modules.

[0005] To achieve the above objectives, the technical solution of this utility model is to design an ultra-miniature connector for a liquid cooling heat dissipation mechanism of an optical module. The ultra-miniature connector includes a male connector and a female connector, with the front end of each of the male and female connectors serving as mating ends. The male connector includes a male connector housing and a male connector spring retainer.

[0006] The male head housing has a circumferential groove on the inner wall of the tail end. The male head spring retaining ring is a non-metallic elastic retaining ring with a conical structure. The small diameter end of the non-metallic elastic retaining ring faces the front end of the male head housing, and the large diameter end of the non-metallic elastic retaining ring engages with the circumferential groove.

[0007] Preferably, the non-metallic elastic retaining ring is a PEEK retaining ring.

[0008] Preferably, the connector female head includes a female head housing and a valve stem. The tail end of the female head housing is provided with an internal thread, and one end of the valve stem is provided with an external thread. The valve stem and the female head housing are connected by the external thread and the internal thread.

[0009] Preferably, the connector female head further includes a connecting tube, one end of which is inserted into the tail end of the female head housing and is provided with an external thread, and the connecting tube and the female head housing are connected by the external thread and the internal thread.

[0010] Preferably, the maximum outer diameter of the ultra-miniature connector is 5 mm.

[0011] The ultra-miniature connector for liquid cooling heat dissipation mechanism of optical modules provided by this utility model has at least the following advantages compared with the prior art:

[0012] Traditional connector male spring retainers are usually made of metal. Manufacturing ultra-miniaturized metal spring retainers is difficult. Therefore, this invention replaces the traditional metal spring retainer with a non-metallic elastic retainer, which helps to reduce the manufacturing difficulty. Furthermore, by setting the non-metallic elastic retainer to a conical structure, this invention allows the non-metallic elastic retainer to be easily installed into the male connector housing, which helps to reduce the assembly difficulty of the non-metallic elastic retainer.

[0013] Traditional connectors typically use snap rings to connect the valve stem and connecting tube to the female housing. This installation method requires a deep snap ring groove to be made in the inner wall of the female housing. However, due to the ultra-small size of the connector and the thin wall of the female housing, it is inconvenient to make a snap ring groove that meets the requirements in the inner wall of the female housing. In addition, slotting the inner wall of the female housing will affect its rigidity. Therefore, this utility model provides an internal thread at the tail end of the female housing and allows the valve stem and connecting tube to share the internal thread of the female housing for installation. This helps to reduce the difficulty of processing and manufacturing, and makes the assembly simple and convenient. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] The specific technical solution of this utility model is as follows:

[0022] In one specific embodiment, such as Figure 1 and Figure 3 As shown, this utility model provides an ultra-miniature connector for a liquid cooling heat dissipation mechanism of an optical module. The ultra-miniature connector includes a male connector and a female connector, with the front end of each of the male and female connectors serving as mating ends. The male connector includes a male connector housing 10 and a male connector spring retainer.

[0023] The male head housing 10 has a circumferential groove 11 on the inner wall of its tail end. The male head spring retainer is a non-metallic elastic retainer 12 with a tapered structure. The small diameter end 13 of the non-metallic elastic retainer 12 is positioned towards the front end of the male head housing 10, and the large diameter end 14 of the non-metallic elastic retainer 12 is engaged with the circumferential groove 11.

[0024] The above-mentioned solution is as follows: This utility model uses a non-metallic elastic retaining ring 12 to replace the traditional metal male head spring retaining ring, which helps to reduce the difficulty of processing and manufacturing; and by setting the non-metallic elastic retaining ring 12 to a conical structure, the non-metallic elastic retaining ring 12 can be smoothly installed into the male head housing 10, which helps to reduce the assembly difficulty of the non-metallic elastic retaining ring 12. When assembling the non-metallic elastic retaining ring 12, the non-metallic elastic retaining ring 12 is elastically deformed from the tail end of the male head housing 10 and pressed into the male head housing 10. When the large diameter end 14 of the non-metallic elastic retaining ring 12 corresponds to the circumferential groove 11, the non-metallic elastic retaining ring 12 elastically returns to its original shape and engages with the circumferential groove 11, thus completing the assembly of the non-metallic elastic retaining ring 11.

[0025] In another specific embodiment, the non-metallic elastic retaining ring 12 is a PEEK retaining ring.

[0026] The above solution is adopted: This utility model utilizes the elasticity and hardness of PEEK material to make a non-metallic elastic retaining ring 12, which is made of PEEK material in the prior art.

[0027] In another specific embodiment, such as Figure 2 and Figure 4 As shown, the female connector includes a female connector housing 20 and a valve stem 21. The tail end of the female connector housing 20 is provided with an internal thread, and one end of the valve stem 21 is provided with an external thread. The valve stem 21 and the female connector housing 20 are connected by the external thread and the internal thread.

[0028] The above solution is adopted: This utility model provides an internal thread at the tail end of the female head housing 20 and an external thread at one end of the valve stem 21, so that the valve stem 21 and the female head housing 20 are connected by the external thread and the internal thread, which replaces the traditional method of opening a retaining groove on the inner wall of the female head housing 20 to assemble the valve stem 21. This helps to reduce the difficulty of processing and manufacturing, and the operation of assembling the valve stem 21 is simple and convenient.

[0029] In another specific embodiment, such as Figure 2 and Figure 5 As shown, the female connector also includes a connecting tube 22. One end of the connecting tube 22 is inserted into the tail end of the female connector housing 20 and is provided with an external thread. The connecting tube 22 and the female connector housing 20 are connected by the external thread and the internal thread.

[0030] The above solution is adopted: By setting an external thread at one end of the connecting pipe 22, the connecting pipe 22 and the female head housing 20 are connected by the external thread and the internal thread, which replaces the traditional method of opening a groove on the inner wall of the female head housing 20 to assemble the connecting pipe 22. This helps to reduce the difficulty of processing and manufacturing, and the operation of assembling the connecting pipe 22 is simple and convenient.

[0031] In another specific embodiment, the maximum outer diameter of the ultra-miniature connector is 5 mm.

[0032] When using the ultra-small connector of this utility model, the male connector is used to connect with the cooling circuit inside the optical module, and the female connector is used to connect with the coolant pipeline of the liquid cooling system. By connecting the male connector and the female connector, the coolant pipeline of the liquid cooling system can be connected with the cooling circuit inside the optical module to cool and dissipate heat from the optical module.

[0033] It should be noted that the other structures of the ultra-small connector of this utility model are the same as those of the connectors in the prior art, and its working method is also the same as that of the prior art. It is used for the connection between pipelines, and will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
