[0047] like Figures 1 to 10As shown, the first aspect of the utility model proposes a connector assembly 100, including a female connector 10 and a male connector 20, the female connector 10 includes a first valve body 11, a first valve core 12 and a first elastic member 13, a first valve body 11 has a first channel 14 formed therein, the first valve core 12 is arranged in the first channel 14 and can move along the first channel 14, the first elastic member 13 is telescopically arranged in the first channel 14, and can drive the first valve core 12 to block the first channel 14; the male connector 20 includes a second valve body 21, a second valve core 22 and a second elastic member 23, a second valve body 21 has a second channel 24 formed therein, the second valve core 22 is arranged in the second channel 24 and can move along the second channel 24, the second elastic member 23 The member 23 is telescopically arranged in the second channel 24, and can drive the second valve core 22 to block the second channel 24. The male connector 20 has a plug-in end 211, and the end of the second channel 24 close to the second valve core 22 is open at the plug-in end 211; the female connector 10 and the male connector 20 have a separation state and a plug-in state; in the separation state, the first elastic member 13 drives the first valve core 12 to block the first channel 14, and the second elastic member 23 drives the second valve core 22 to block the second channel 24; in the plug-in state, the plug-in end 211 is plugged into the end of the first channel 14 close to the first valve core 12, the first valve core 12 abuts against the second valve core 22, the first elastic member 13 and the second elastic member 23 are in a compressed state, and the first channel 14 is connected to the second channel 24.

[0048] It can be understood that the first valve body 11 and the second valve body 21 can be cylindrical structures, and the first channel 14 and the second channel 24 are set along the axial direction thereof. A tubular structure with a slightly smaller diameter can be set at one axial end of the first valve body 11 to facilitate connection with the pipeline, and a tubular structure with a slightly smaller diameter can be set at one axial end of the second valve body 21 to facilitate connection with another pipeline. The first valve body 11 and the second valve body 21 can be connected to the pipeline by a clamp or a screw connection. The first valve core 12 and the second valve core 22 can be cylindrical structures, and the first elastic member 13 and the second elastic member 23 can be spring structures or other structures with elastic force. A protruding part can be set in the first channel 14, such as a boss structure for fixing one end of the first elastic member 13, and the other end of the first elastic member 13 is connected to the first valve core 12. Another protruding part can also be set in the first channel 14, such as a ring platform structure adapted to the outer surface of the first valve core 12, so that the first elastic member 13 can drive the first valve core 12 to abut against the ring platform structure to close the first channel 14. Correspondingly, a protruding portion may also be provided in the second channel 24, such as a boss structure for fixing one end of the second elastic member 23, the other end of the second elastic member 23 is connected to the second valve core 22, and another protruding portion may also be provided in the second channel 24, such as an annular platform structure adapted to the outer surface of the second valve core 22, so that the second elastic member 23 can drive the second valve core 22 to abut against the annular platform structure to close the second channel 24. The plug-in end 211 may be an annular wall structure located at one axial end of the second valve body 21, and the annular wall structure defines a part of the second channel 24. There is a gap between one axial end of the first channel 14 and the first valve core 12, and the gap can accommodate the insertion of the plug-in end 211. With the insertion of the second valve body 21, the second valve core 22 abuts against the first valve core 12, and the interaction causes the second valve core 22 and the first valve core 12 to move toward the inside of the second valve body 21 and the first valve body 11 respectively, thereby separating the second valve core 22 from the annular structure, and the first valve core 12 is also separated from the corresponding annular structure, so that the first channel 14 and the second channel 24 are opened, and the first channel 14 is connected to the second channel 24, so that the pipeline connected to the male connector 20 is connected to the pipeline connected to the female connector 10.

[0049] The male connector 20 and the female connector 10 of the utility model can disconnect the internal channel by driving the valve core through the elastic member in the separated state, so that the flow path of the refrigerant is cut off, reducing the leakage of the refrigerant. And the plug-in end 211 of the male connector 20 can be plugged into the first channel 14 of the female connector 10, so that the male connector 20 and the female connector 10 are in the plug-in state, at which time the first valve core 12 and the second valve core 22 abut against each other and move to the inside of the connector, thereby connecting the first channel 14 and the second channel 24 to each other, so that the flow path of the refrigerant is connected, avoiding the refrigerant pipe being connected by welding, which causes damage to the energy storage system.

[0050] In some embodiments of the utility model, a first flow channel 121 and a second flow channel 122 are formed in the first valve core 12, one end of the first flow channel 121 is open at one axial end of the first valve core 12 and communicates with the first channel 14, the second flow channel 122 extends along the circumference of the first valve core 12, the inner peripheral side of the second flow channel 122 is communicated with the other end of the first flow channel 121, the outer peripheral side of the second flow channel 122 is open at the outer peripheral surface of the first valve core 12 and communicates with the first channel 14, the first flow channel 121;

[0052] It can be understood that the first valve core 12 and the second valve core 22 are cylindrical structures, and the diameters of the first valve core 12 and the second valve core 22 are substantially consistent with the first channel 14 and the second channel 24, so that the fluid can flow through the flow channels inside the first valve core 12 and the second valve core 22. A T-shaped flow channel can be provided inside the first valve core 12, and the first flow channel 121 extends along the axial direction of the first valve core 12. One end of the first flow channel 121 is open at one axial end of the first valve core 12 to communicate with the first channel 14. The second flow channel 122 is annular, and its inner peripheral side is communicated with the other end of the first flow channel 121, and its outer peripheral side is open to communicate with the first channel 14, so that the fluid from the pipeline connected to the female connector 10 can enter the first flow channel 121 through the first channel 14, and then flow around to flow out of the first valve core 12, and then enter the first channel 14. The diameter of the first flow channel 121 can be close to the diameter at the entrance of the first channel 14, so that the flow resistance is reduced. The axial width of the second flow channel 122 along the first valve core 12 can be set as wide as possible according to the length of the first valve core 12, so that the flow area of ​​the second flow channel 122 is the same as that of the first flow channel 121, and the flow area at the cutoff point between the first valve core 12 and the first valve body 11 can be adjusted by the elasticity of the elastic member and the length of the first valve core 12, that is, after the female connector 10 is connected to the male connector 20, the distance of the first valve core 12 moving inward is adjusted, and the flow area at the cutoff point can be set to be consistent with the flow area of ​​the second channel 24, so that the flow resistance is reduced as much as possible, and the compactness and large flow of the connector assembly 100 coexist, thereby improving the user experience. The third flow channel 221 and the fourth flow channel 222 of the male connector 20 also have the same beneficial effects as the first flow channel 121 and the second flow channel 122, which will not be repeated here.

The first sealing platform 15 can be an integrated structure with the first valve body 11. A protruding first limiting platform 16 may also be provided in the first channel 14, and the first limiting platform 16 is used to axially limit the first valve core 12, so that when the male connector 20 is connected to the female connector 10, the first valve core 12 can move a certain distance to the depth of the first channel 14 and then be blocked and stopped by the first limiting platform 16, thereby improving the reliability of the movement of the first valve core 12. Specifically, the first limiting platform 16 may be an annular structure, or at least one may be provided along the circumference of the first valve core 12, and the first limiting platform 16 may be an integrated structure with the first valve body 11.

[0056] Correspondingly, a second sealing platform 25 may be provided in the second channel 24, and the second sealing platform 25 may be an annular boss structure provided in the second channel 24. The diameter of the portion of the second valve core 22 between the second sealing platform 25 and the second elastic member 23 may be set to be larger than the inner diameter of the second sealing platform 25, and the diameter of the portion of the second valve core 22 extending into the hole formed by the second sealing platform 25 may be less than or equal to the inner diameter of the second sealing platform 25, so that the second valve core 22 can be pressed against the side of the second sealing platform 25 facing the second elastic member 23 under the elastic force of the second elastic member 23, and part of the second valve core 22 is provided in the hole formed by the second sealing platform 25, so as to cut off the second channel 24. The second sealing platform 25 may be an integrated structure with the second valve body 21.

Specifically, the second limiting platform 26 may be an annular structure, or at least one may be provided along the circumference of the second valve core 22, and the second limiting platform 26 may be an integrated structure with the second valve body 21.

[0057] In some embodiments of the utility model, the plug-in end 211 is provided with an annular groove 212, which surrounds the second channel 24, and the annular groove 212 is adapted to one end of the first valve body 11 close to the first valve core 12. In the plug-in state, one end of the first valve body 11 close to the first valve core 12 is plugged into the annular groove 212.

[0058] It is understandable that an annular groove 212 may be provided at the plug end 211 of the male connector 20. The shape of the annular groove 212 is adapted to one axial end of the first valve body 11. The annular groove 212 may be defined by a solid structure defining a portion of the second channel 24 located at the plug end 211 and an annular wall provided on the periphery of the solid structure. By providing the annular groove 212, when the male connector 20 is plugged into the first channel 14 of the female connector 10 to achieve connection, the end of the female connector 10 can be snapped into the annular groove 212, thereby improving the reliability of the connection, strengthening the sealing effect of the connection, and reducing the phenomenon of refrigerant leakage. A third sealing ring 19 can be provided at the plug-in end 211 of the female connector 10 or the male connector 20. Specifically, the third sealing ring 19 can be sleeved on the outer peripheral surface of the plug-in end 211 of the male connector 20, or sleeved on the inner side of the first channel 14 of the female connector 10, so that when the male connector 20 is plugged into the first channel 14 of the female connector 10 to achieve connection, the third sealing ring 19 can seal the gap between the plug-in end 211 and the female connector 10, thereby strengthening the sealing and reducing refrigerant leakage.
