[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] See also Figures 1 to 4 , a splash-proof blind plug connector of the utility model comprises a plug connector 2, a cavity 3 and a drive assembly;

[0030] The cavity 3 is provided with a through hole 31, a cover plate 32 and a liquid guide port 33. The through hole 31 is provided along the width direction of the cavity 3 and penetrates the cavity 3. One end of the plug connector 2 is connected with an external liquid supply pipe or a liquid return pipe. The body of the plug connector 2 is located in the through hole 31. The cavity 3 moves relative to the plug connector 2. The cover plate 32 is provided in the cavity 3.

[0031] The driving assembly is disposed in the cavity 3 , and the driving assembly drives the cover plate 32 to move so that the cover plate 32 covers the plug connector 2 or moves away from the plug connector 2 . When the cover plate 32 moves away from the plug connector 2 , the plug connector 2 is in an exposed state.

[0032] Specifically, in this embodiment, the plug connector 2 is connected to the external liquid supply pipe and the liquid return pipe. The number of the plug connectors 2 is two, one plug connector 2 is connected to the liquid supply pipe, and the other plug connector 2 is connected to the liquid return pipe. The cavity 3 is processed with two through holes 31, two cover plates 32 and a liquid guide port 33. One plug connector 2 passes through one through hole 31. Preferably, the cover plate 32 is rotatably connected to the driving assembly. One cover plate 32 is used to separate one through hole 31, and the central axis of the cover plate 32 coincides with the central axis of the through hole 31. The drive assembly is arranged in the cavity 3, and the drive assembly drives the cover plate 32 to rotate so that the plug connector 2 is covered or exposed. The drive assembly drives the cover plate 32 to rotate so that the through hole 31 is connected or separated into two sections. When the cover plate 32 rotates and moves away from the through hole 31, the through hole 31 is in a connected state, and the plug connector 2 is in a exposed state. When the cover plate 32 rotates and separates the through hole 31, the plug connector 2 is in a state covered by the cover plate 32. The working principle is as follows: when there is no need to dissipate heat for the server board, the cover The central axis of the plate 32 coincides with the central axis of the perforation 31 so that the cover plate 32 blocks the perforation 31, and the plug connector 2 is covered by the cover plate 32 along the axial direction of the perforation 31. When the server board needs to dissipate heat, the plug end of the server board gradually approaches the cavity 3 and pushes the cavity 3 to move in the direction close to the liquid supply pipe or the liquid return pipe. Under the action of the driving component, the cover plate 32 rotates so that the central axis of the cover plate 32 intersects the central axis of the perforation 31 until the plug connector 2 is exposed. The plug connector 2 then moves along the axial direction of the perforation 31 and gradually exposes the cavity 3 until the plug end of the plug connector 2 connected to the server board is connected. The external cooling medium enters the server board through the blind plug connector to achieve the purpose of cooling the server board. The cooling liquid overflowing from the plug connector 2 drips into the cavity 3, and the cooling liquid splashed by the plug connector 2 falls into the cavity 3, and finally flows out from the liquid guide port 33, which is convenient for collecting the cooling liquid, avoiding secondary pollution to the cabinet, and ensuring the safety and reliability of the server board.

[0033] By setting a cavity 3 consisting of a perforation 31, a cover plate 32 and a liquid guide port 33, a driving component is set in the cavity 3 and drives the cover plate 32 to move so that the plug connector 2 is covered or exposed, thereby achieving the purpose of connecting the plug connector 2 with the external server single board plug-in terminal. The setting of the cover plate 32, under the action of the driving component, separates or connects the perforation 31 to achieve the purpose of covering or exposing the plug connector 2, thereby avoiding the plug connector 2 from being exposed when not connected, improving the sealing of the plug connector 2, reducing pollution, and improving the safety and service life of the blind plug connector. At the same time, it can ensure that when the plug connector 2 is disconnected, the coolant is prevented from splashing into other spaces.

[0034] The splash-proof blind plug connector also includes a mounting plate 1, the mounting plate 1 is spaced apart from the cavity 3, one end of the plug connector 2 protrudes out of the mounting plate 1 and is connected to an external liquid supply pipe or a liquid return pipe, the driving assembly includes a rack 41, a gear 42, a first elastic member 43 and a second elastic member 45, the rack 41 is slidably connected to the cavity 3, the gear 42 is arranged in the cavity 3, the rack 41 is meshed with the gear 42, the gear 42 is linked to the cover plate 32, and the two ends of the first elastic member 43 are respectively connected to the mounting plate 1 and the outer wall of the cavity 3, The second elastic member 45 is located in the cavity 3, and the two ends of the second elastic member 45 are respectively connected to the inner wall of the cavity 3 and the rack 41, and the first elastic member 43 drives the cavity 3 to reset. Preferably, the mounting plate 1 is located outside the cavity 3 and close to the external liquid supply pipe or the liquid return pipe. The mounting plate 1 is used to fix the first elastic member 43. In the initial state, the rack 41 protrudes out of the cavity 3. When the external server single board plug-in end approaches the cavity 3, it first conflicts with the rack 41, and the rack 41 is pushed, and the second elastic member 45 is compressed to generate a compression elastic force, and synchronously meshes with the rack 41. The gear 42 rotates, and the cover plate 32 linked with the gear 42 rotates, so that the through hole 31 is in a connected state, so that the plug connector 2 is in an exposed state, and then the plug end of the external server single board continues to approach the cavity 3 and pushes the cavity 3 to move in the direction close to the mounting plate 1, so that the plug connector 2 extends out of the through hole 31, and the first elastic member 43 arranged between the mounting plate 1 and the cavity 3 is compressed to generate a compression elastic force. After the external plug end is connected to the plug connector 2, the heat dissipation and cooling process of the server single board in the external cabinet is realized. When the server single board that needs to be replaced is cooled by heat dissipation, The external server single board plug-in end is separated from the plug connector 2, the compression elastic force generated by the first elastic member 43 pushes the cavity 3 away from the mounting plate 1 to reset the cavity 3 away from the mounting plate 1, and the plug connector 2 retracts into the through hole 31. The compression elastic force generated by the second elastic member 45 pushes the rack 41 away from the inner wall of the cavity 3, the rack 41 is reset, and the gear 42 rotates in the opposite direction. The linkage cover plate 32 rotates to block the through hole 31 and cover the plug connector 2 to shield and protect the plug connector 2, thereby reducing the contamination of the coolant by the outside through the exposed plug connector 2 and preventing the coolant from splashing into other spaces.

[0035] The driving assembly also includes a first guide member 44, one end of which is connected to the mounting plate 1, and the other end of the first guide member 44 passes through the cavity 3. The first elastic member 43 is sleeved on the first guide member 44 to ensure the stability of the compression or rebound direction of the first elastic member 43, thereby ensuring the stability of the movement direction of the cavity 3 and accurately positioning the external server board plug-in end.

[0036] The cavity 3 further comprises a guide groove 34 , and the rack 41 is slidably connected in the guide groove 34 , so as to ensure the stability of the rack 41 in the reciprocating direction, and ensure the stability of the gear 42 and the cover plate 32 linked with the gear 42 in the rotation direction.

[0037] The rack 41 includes a plate body 411, a tooth portion 412 and an open groove. The open groove starts from the end of the plate body 411 and extends in a direction away from the end. The second elastic member 45 is located in the open groove. The setting of the open groove facilitates processing and reduces the overall weight of the rack 41, making it convenient to push the rack 41 to move back and forth. At the same time, the open groove accommodates the second elastic member 45, reducing the space occupied by the drive component, so that the overall structure of the blind plug connector is compact and fully functional.

[0038] The rack 41 also includes a partition 414, which is located in the open groove and divides the open groove into a closed cavity and an open cavity 413. The two ends of the second elastic member 45 are respectively connected to the cavity 3 and the partition 414, so as to further accurately control the elastic force of the second elastic member 45, reduce the use length of the second elastic member 45, and reduce costs.

[0039] The driving assembly also includes a second guide member 46, one end of which is fixed to the cavity 3, the second guide member 46 passes through the partition 414 and extends into the closed cavity, the second elastic member 45 is sleeved on the second guide member 46, and the setting of the second guide member 46 guides the extension and retraction of the second elastic member 45, thereby ensuring the consistency of the reciprocating direction of the rack 41.

[0040] The cavity 3 further includes a liquid guide plate 35 , which is disposed at the liquid guide port 33 and protrudes out of the cavity 3 , so as to facilitate centralized drainage of the cooling liquid in the cavity 3 , prevent the cooling liquid from dripping into the cabinet, and reduce secondary pollution.

[0041] The liquid guide plate 35 is arc-shaped, which is convenient for collecting the coolant.
