Description

Technical Field

[0001] This utility model relates to the field of sealing connector technology, and in particular to an end-face sealing connector. Background Technology

[0002] In high-purity fluid transport processes in industries such as lithium battery manufacturing, semiconductors, and pharmaceuticals, the sealing performance and cleanliness level of quick-connect connectors are crucial. Traditional quick-connect connectors mostly employ snap-fit ​​mechanical locking and radial sealing methods, and the flow channels typically contain components such as metal springs, which are prone to particulate contamination due to friction, making it difficult to meet the requirements of high-purity media transport. Furthermore, existing structures suffer from insufficient sealing reliability, low pressure resistance, and significant vacuum leakage under high pressure and vacuum conditions, and rely on manual operation, making them unsuitable for automated production. Therefore, there is an urgent need for a quick-connect solution that achieves zero contamination, high sealing, high pressure resistance, and is suitable for automated docking. Utility Model Content

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 An end-face sealing connector according to an embodiment of the present invention includes a first connector 100 and a second connector 200. The first connector 100 includes a first body 101, a first valve core 102, and a sliding sleeve 103. The second connector 200 includes a second body 201 and a second valve core 202. A first elastic member 104 is provided between the sliding sleeve 103 and the first body 101, surrounding the outer periphery of the first valve core 102. The first elastic member 104 is used to keep the first valve core 102 in contact with the end of the sliding sleeve 103 at all times, thereby achieving a seal. A second elastic member 206 is provided on the outer periphery of the second valve core 202. The second elastic member 206 is used to keep the second valve core 202 continuously in contact with the end of the second body 201, thereby achieving a seal. When the two ends are not connected, with the help of the first elastic member 104 and the second elastic member 206, a good sealing state can be maintained between the first valve core 102 and the sliding sleeve 103, and between the second valve core 202 and the second body 201, effectively preventing media leakage.

[0023] It is understood that the first valve core 102 has a first inner channel 107, and the second valve core 202 has a second inner channel 204. The first elastic element 104 and the second elastic element 206 are respectively arranged on the outer periphery of the first valve core 102 and the second valve core 202. In fact, the first elastic element 104 and the second elastic element 206 are located on the outer periphery of the first inner channel 107 and the second inner channel 204, respectively. Therefore, the medium will not come into contact with the first elastic element 104 and the second elastic element 206 when flowing, thereby avoiding medium contamination due to material shedding or corrosion of the elastic elements. It also facilitates cleaning and maintenance of the connector interior, making it suitable for applications requiring high cleanliness. In this embodiment, both the first elastic element 104 and the second elastic element 206 are helical springs.

[0024] Reference Figure 2 It is understandable that when the first connector 100 and the second connector 200 are docked (hereinafter referred to as "dockment"), the end of the first valve core 102 will abut against and push the second valve core 202 to move backward, while the end of the second body 201 will also push the sliding sleeve 103 to move backward. During this process, both the sliding sleeve 103 and the first valve core 102 will retract. With the structural displacement, a first channel 105 is formed inside the first body 101, and a second channel 203 is formed inside the second body 201. The first channel 105 and the second channel 203 are interconnected, forming a complete flow channel, thereby realizing the smooth transport of the medium.

[0025] Reference Figure 3 and Figure 4 The first channel 105 is located on the outer periphery of the first valve core 102. Specifically, the outer periphery of the first valve core 102 has a recess 113, and there is a cavity between the outer peripheral wall of the recess 113 and the inner peripheral wall of the sliding sleeve 103. During docking, when the sliding sleeve 103 moves away from the second connector 200, a gap is formed between the end of the sliding sleeve 103 and the first valve core 102, and this gap communicates with the cavity, thereby forming the first channel 105.

[0026] Furthermore, the first valve core 102 is also provided with a first connecting pipe 106 for connecting the first inner channel 107 and the first channel 105, so that the medium can enter the first channel 105 from the first inner channel 107 through the first connecting pipe 106 to realize medium flow. In some embodiments, the first valve core 102 may be provided with multiple first connecting pipes 106, which are uniformly arranged along the circumference of the first valve core 102 to improve flow efficiency and flow rate.

[0027] The second channel 203 is located on the outer periphery of the second valve core 202. Specifically, there is a cavity between the outer peripheral wall of the second valve core 202 and the inner peripheral wall of the second body 201. When sealed, this cavity is not connected to the outside. When mating, when the second valve core 202 moves into the interior of the second body 201, there is a gap between the end of the second valve core 202 and the end of the second body 201. This gap connects the outside and the cavity, thereby forming the second channel 203.

[0028] Furthermore, the second valve core 202 is provided with a second connecting pipe 210, which is used to connect the second inner channel 204 and the second channel 203, so that the medium can enter the second inner channel 204 from the second channel 203 through the second connecting pipe 210. Similarly, the second valve core 202 may also be provided with multiple second connecting pipes 210, arranged circumferentially, to optimize the medium flow performance.

[0029] It is understandable that during docking, the medium can flow from the first joint to the second joint, or from the second joint to the first joint.

[0030] To improve sealing performance, a first sealing ring 108 is installed on the outer periphery of the first valve core 102. An arc-shaped first sealing surface 111 is machined on the inner peripheral wall of the sliding sleeve 103. In the unconnected state, the first sealing surface 111 is in close contact with the outer wall of the first sealing ring 108 along the axial direction of the first valve core 102, achieving axial sealing and preventing media leakage. A second sealing ring 205 is installed on the outer periphery of the second valve core 202, and a second sealing surface 207 is provided on the inner peripheral wall of the second body 201. In the unconnected state, the second sealing surface 207 is in close contact with the outer wall of the second sealing ring 205 along the axial direction of the second valve core 202, achieving axial sealing.

[0031] To further enhance the sealing effect, the inner peripheral wall of the sliding sleeve 103 is also provided with a third sealing surface 112. In the unconnected state, the third sealing surface 112 is in close contact with the outer side wall of the first sealing ring 108 along the radial direction of the first valve core 102, achieving radial sealing. Together with the axial sealing, it significantly improves the sealing reliability and prevents leakage when the sliding sleeve 103 undergoes slight axial movement.

[0032] Furthermore, a third sealing ring 109 is installed between the radial outer peripheral wall of the first valve core 102 and the inner wall of the sliding sleeve 103 to prevent the medium from seeping into the area where the first elastic element 104 is located. A fourth sealing ring 208 is installed between the radial outer peripheral wall of the second valve core 202 and the second body 201, which also serves to isolate the medium and protect the second elastic element 206. This design further reduces the risk of contamination and extends the service life of the elastic element.

[0033] In a further embodiment, refer to Figure 5The second body 201 contains an inner tube 211. In fact, the second inner channel 204 is located within the inner tube 211. Simultaneously, the second valve core 202 is sleeved on the outer periphery of the inner tube 211, and the second elastic element 206 is sleeved on the outer periphery of the inner tube 211, ensuring that the second elastic element 206 does not contact the medium in the second inner channel 204. Therefore, to achieve a seal, a fifth sealing ring 212 is provided between the inner peripheral wall of the second valve core 202 and the outer peripheral wall of the inner tube 211 to prevent the flowing medium from contacting the second elastic element 206.

[0034] To achieve precise docking, the end of the sliding sleeve 103 is machined with a positioning groove 110, and the end of the second body 201 is provided with a boss 209. When the first connector 100 docks with the second connector 200, the boss 209 can be inserted into the positioning groove 110, serving as a guide and positioning element to ensure a smooth and accurate docking process and avoid misalignment or skewness. Furthermore, the positioning groove 110 and the boss 209 extend circumferentially around the first body 101 and the second body 201, respectively.

[0035] It is understood that the end-face sealing connector in this embodiment is suitable for fluid transport systems in high-cleanliness, high-pressure, or high-vacuum environments, such as lithium battery manufacturing, semiconductor processes, and biopharmaceuticals. Its structural design balances sealing performance, cleanliness level, and ease of operation, enabling rapid and automatic docking to meet the needs of modern industrial automated production.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
