[0047] In vehicles, connectors are essential structures that connect two pipe sections. During maintenance, both pipe sections need to be disassembled, and it's crucial to ensure no fluid leakage occurs. In related technologies, valves are typically installed in both pipe sections to control the fluid flow. However, this not only complicates the pipe structure but also increases the risk of leakage due to the added valve installation.

[0048] Therefore, this application provides a connector device in which the female connector assembly and the male connector assembly each seal themselves when separated; when the female connector assembly and the male connector assembly are combined and connected, they interact to move the sealing movable part, thereby making the female connector assembly and the male connector assembly conductive. The detachable connection of the female connector assembly and the male connector assembly enables the disassembly and assembly of the connector device without the need for additional valves, simplifying operation.

[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0050] Combination Figure 1 and Figure 2 This application provides a connector device, which includes a male connector assembly 100 and a female connector assembly 200. The male connector assembly 100 and the female connector assembly 200 are used to connect two pipe sections, and the pipes at both ends can be connected or disconnected through the male connector assembly 100 and the female connector assembly 200.

[0051] When the male connector assembly 100 and the female connector assembly 200 are separated, each of the male connector assembly 100 and the female connector assembly 200 seals its port, preventing fluid leakage from the connecting pipe.

[0052] When the male connector assembly 100 and the female connector assembly 200 are used together, the channel formed by the male connector assembly 100 and the channel formed by the female connector assembly 200 are connected, thereby making the two pipe sections connected by the male connector assembly 100 and the female connector assembly 200 conductive.

[0053] Combination Figure 3 and Figure 4 The male connector assembly 100 of this application embodiment includes: a first body 110. The first body 110 is configured to form a first channel 111, and a first end of the first channel 111 is used to communicate with a pipe.

[0054] In some embodiments, the first body 110 includes a first shell portion 112 and a second shell portion 113, which are fixedly connected. The first shell portion 112 and the second shell portion 113 can be fixedly connected along the extension direction of the first channel 111. The first shell portion 112 can be used to be fixedly connected to the female connector assembly 200, and the second shell portion 113 can be used to connect to a pipe.

[0055] For example, the first housing portion 112 and the second housing portion 113 are threaded together, and the connection method is simple and reliable.

[0056] For example, the first shell portion 112 and the second shell portion 113 are interference-fitted, which has a simple structure and is easy to assemble.

[0057] In this embodiment, the first shell portion 112 and the second shell portion 113 are tubular, and the channels of the first shell portion 112 and the channels of the second shell portion 113 are combined to form the first channel 111.

[0058] In this embodiment of the application, the first shell portion 112 and the second shell portion 113 are fixedly connected to form the first channel 111; moreover, the first body 110 is formed by connecting two parts, which facilitates the assembly of the internal structure.

[0059] In some embodiments, the first channel 111 has a circular cross-section, which is not only easy to process but also facilitates sealing.

[0060] The male connector assembly 100 of this application embodiment further includes a first movable member 120 located within a first channel 111. The first movable member 120 is configured to move along the extension direction of the first channel 111.

[0061] When the male connector assembly 100 and the female connector assembly 200 are separated, the first movable member 120 is elastically pressed into the first channel 111, and the first movable member 120 is sealed to the inner wall of the first channel 111 to block the first channel 111, thereby enabling the male connector assembly 100 to block the pipe it is connected to.

[0062] In this embodiment, when the male connector assembly 100 and the female connector assembly 200 are separated, the first movable member 120 is elastically pressed against the end of the first housing portion 112 that is away from the second housing portion 113. This can block the first channel 111 and facilitate the female connector assembly 200 to operate the first movable member 120 when the male connector assembly 100 and the female connector assembly 200 are assembled.

[0063] In some embodiments, a first sealing ring 310 is provided between the first movable member 120 and the inner wall surface of the first channel 111 to improve the sealing between the first movable member 120 and the inner wall surface of the first channel 111, thereby blocking the first channel 111 and preventing fluid leakage from the first channel 111.

[0064] For example, a first sealing groove is provided on at least one of the inner wall surfaces of the first movable member 120 and the first channel 111, and a first sealing ring 310 is disposed in the first sealing groove. This can limit the position of the first sealing ring 310 and prevent the first sealing ring 310 from failing to return to the position between the first movable member 120 and the second channel 211 after the first movable member 120 moves.

[0065] Combination Figure 4 A first sealing groove is provided on the first movable part 120, and a first sealing ring 310 is fitted into the first sealing groove. When the male connector assembly 100 and the female connector assembly 200 are separated, the first sealing ring 310 seals the inner wall of the first movable part 120 and the first channel 111.

[0066] If the first sealing ring 310 detaches from the first sealing groove, when the male connector assembly 100 separates from the female connector assembly 200, the first sealing ring 310 may not be able to return to its original position between the first moving member 120 and the first channel 111. Figure 2 When the male connector assembly 100 and the female connector assembly 200 are engaged, the first sealing ring 310 moves with the movement of the first movable member 120, which can ensure the stability of the first sealing ring 310 in sealing the first movable member 120 and the inner wall of the first channel 111.

[0067] In this embodiment, the first movable member 120 is elastically pressed within the first channel 111. In some embodiments, at least a portion of the first movable member 120 is elastic, thereby causing the first movable member 120 to be elastically pressed within the first channel 111.

[0068] In some embodiments of this application, the male connector assembly 100 further includes a first elastic member 130. The first elastic member 130 is configured to press the first movable member 120 into the first channel 111 when the male connector assembly 100 is separated from the female connector assembly 200.

[0069] The first elastic element 130 is compressed and confined within the first channel 111, that is, the first elastic element 130 is a compression elastic element.

[0070] For example, the channel formed by the second shell portion 113 has a limiting boss at one end near the first shell portion 112, and one end of the first elastic member 130 abuts against the limiting boss. The other end of the first elastic member 130 is connected to the first movable member 120. For example, the other end of the first elastic member 130 abuts against the first movable member 120, which can both elastically press the first movable member 120 and eliminate the need for additional connection structures, making the internal structure of the male connector assembly 100 simple.

[0071] The first elastic element 130 can be a spring, an elastic sleeve, or other structure capable of elastic deformation. In the accompanying drawings of the embodiments of this application, the first elastic element 130 is shown as a spring.

[0072] In this embodiment, when the male connector assembly 100 and the female connector assembly 200 are engaged, the first end of the first channel 111 and the second end of the first channel 111 are connected. It can be understood that the arrangement of the first elastic element 130 does not affect the fluid flow through the first channel 111. As shown in the figure, the first elastic element 130 is a spring; for example, the first elastic element 130 is an elastic sleeve, which forms a through hole to allow fluid flow.

[0073] In this embodiment, the male connector assembly 100 uses a first elastic member 130 to elastically press the first movable member 120 against the first channel 111, thereby blocking the first channel 111. Furthermore, the first elastic member 130 can deform under force, allowing the first movable member 120 to move along the extension direction of the first channel 111, thus enabling the first channel 111 to conduct. The first elastic member 130 and the first movable member 120 are separate components, facilitating the assembly of the internal structure of the male connector assembly 100.

[0074] Continue to refer to Figure 4 In some embodiments, the inner wall of the first channel 111 is provided with a first stop 1111, which is used to limit the first movable member 120 and prevent the first movable member 120 from coming out of the first channel 111.

[0075] The second end of the first channel 111 is provided with a protrusion facing the center to form a first stop 1111. The first stop 1111 is annular, and the end face of the first stop 1111 abuts against the first movable member 120, thereby restricting the first movable member 120; the annular side of the first stop 1111 is sealed to the first movable member 120, thereby blocking the first channel 111.

[0076] Combination Figure 4 and Figure 5The first movable component 120 includes a first sealing portion 121, which is sealed to a first stop portion 1111 to block the first channel 111. For example, a first sealing ring 310 is provided between the first sealing portion 121 and the first stop portion 1111.

[0077] In some embodiments, the first channel 111 includes a first channel segment and a second channel segment that are axially connected, wherein the diameter of the first channel segment is smaller than the diameter of the second channel segment. A first stop portion 1111 surrounds the first channel segment. A first elastic member 130 is disposed within the second channel segment.

[0078] Combination Figure 4 When the male connector assembly 100 and the female connector assembly 200 are separated, a first sealing ring 310 is provided between the first sealing part 121 and the inner wall of the first channel.

[0079] Combination Figure 2 and Figure 5 When the male connector assembly 100 and the female connector assembly 200 are engaged, a first flow gap 122 is formed between the first sealing part 121 and the inner wall of the first channel 111. Specifically, the first flow gap 122 is formed between the first sealing part 121 and the second channel section, and the first flow gap 122 connects the portions of the first channel 111 at both ends of the first movable member 120, that is, connects the first and second sections of the first channel 111, so that the first channel 111 is conductive.

[0080] Continue to refer to Figure 4 and Figure 5 The first movable member 120 also includes a first connecting portion 123, the outer diameter of which is larger than the outer diameter of the first sealing portion 121. The first connecting portion 123 cooperates with the second channel, thereby enabling the first connecting portion 123 to move along the first channel 111 and provide guidance for the movement of the first movable member 120.

[0081] The end of the first elastic member 130 abuts against the first connecting portion 123. The elastic force of the first elastic member 130 acts on the first connecting portion 123, causing the first movable member 120 to block the first channel 111. When the first movable member 120 is subjected to the abutting force, the first movable member 120 moves toward the first end of the first channel 111 and compresses the first elastic member 130.

[0082] The end face of the first connecting portion 123 facing the first sealing portion 121 abuts against the end face of the first stop portion 1111, thereby preventing the first movable member 120 from dislodging from the first channel 111. In some embodiments, the first connecting portion 123 and the first stop portion 1111 are engaged by a bevel, which helps to improve the reliability and stability of the engagement between the first movable member 120 and the first stop portion 1111.

[0083] Combination Figure 5 The first connecting portion 123 forms a first flow channel 1231. Combined with... Figure 2 When the male connector assembly 100 and the female connector assembly 200 are engaged, the first flow passage 1231 is configured to connect the first channel 111 and the first flow gap 122, thereby making the first channel 111 conductive.

[0084] In some embodiments, the first flow channel 1231 includes a first central channel and a plurality of first side channels. The first central channel extends axially along the first connecting portion 123 and is coaxially arranged with the first connecting portion 123. The plurality of first side channels are arranged circumferentially spaced along the first central channel. One end of each first side channel communicates with the first central channel, and the other end of each first side channel is disposed on the end face of the first connecting portion 123 facing the first sealing portion 121. This allows the first side channels to connect the first flow gap 122 and the first central channel, thereby allowing the first flow channel 1231 to connect with the first channel segment through the first flow gap 122.

[0085] In some embodiments, a first tapered portion 124 is provided on the end face of the first central channel. The first tapered portion 124 may be pyramidal or conical. The tip of the first tapered portion 124 is disposed away from the end face of the first central channel.

[0086] A first conical portion 124 is provided in the first central channel of the first flow channel 1231, so that when the fluid in the first channel 111 flows from the first end to the second end, it can be dispersed and guided to the first side channel in the first conical portion 124, thereby reducing local impact force.

[0087] With the above configuration, the male connector assembly 100 of this application embodiment forms a first channel 111 by setting a first body 110 for communicating with a pipeline; by setting a first movable member 120 to elastically press into the first channel 111, the first channel 111 is blocked to prevent fluid leakage from the first channel 111; the first movable member 120 is configured to move along the first channel 111, thereby making the first channel 111 open.

[0088] Combination Figure 2 , Figure 6 as well as Figure 7 The female connector assembly 200 of this application embodiment includes a second body 210. The second body 210 is configured to form a second channel 211, and a first end of the second channel 211 is used to communicate with a pipe.

[0089] In some embodiments, the second body 210 includes a third shell portion 212 and a fourth shell portion 213, which are fixedly connected. The third shell portion 212 and the fourth shell portion 213 can be fixedly connected along the extending direction of the second channel 211. The third shell portion 212 can be used for fixed connection with the male connector assembly 100, and the fourth shell portion 213 can be used for connecting a pipe. For example, the fourth shell portion 213 can be a bamboo-joint tube, facilitating connection and sealing with a pipe.

[0090] For example, the third shell 212 and the fourth shell 213 are threaded together, which is a simple and reliable connection method.

[0091] For example, the third shell portion 212 and the fourth shell portion 213 are interference-fitted, which has a simple structure and is easy to assemble.

[0092] In this embodiment, the third shell portion 212 and the fourth shell portion 213 are tubular, and the channels of the third shell portion 212 and the fourth shell portion 213 are combined to form the second channel 211.

[0093] The third shell portion 212 and the fourth shell portion 213 of this application embodiment are fixedly connected to form the second channel 211; moreover, the second body 210 is formed by connecting two parts, which facilitates the assembly of the internal structure.

[0094] In some embodiments, the second channel 211 has a circular cross-section, which is not only easy to process but also facilitates sealing.

[0095] The female connector assembly 200 of this application embodiment further includes a stop member 230, which is fixed within the second channel 211. The stop member 230 may include a stop end and a fixed end. The fixed end fixes the stop member 230 within the second channel 211, and the stop end is used to abut against the first movable member 120 of the male connector assembly 100 to push the first movable member 120 to move along the first channel 111.

[0096] When the male connector assembly 100 and the female connector assembly 200 are engaged, the abutment member 230 pushes the first movable member 120 to move along the first channel 111, causing a portion of the abutment member 230 to extend into the first channel 111, with a gap between the abutment member 230 and the inner wall surface of the first channel 111. That is, the abutment member 230 extending into the first channel 111 does not affect the conductivity of the first channel 111.

[0097] The abutment 230 is located within the second channel 211, and the abutment 230 does not affect the conduction of the second channel 211. That is, there is a fluid flow gap between the abutment 230 and the inner wall surface of the second channel 211.

[0098] In some embodiments, the abutment 230 is rod-shaped, and the extending direction of the abutment 230 is the same as the extending direction of the second channel 211, so that there is a large gap between the abutment 230 and the inner wall surface of the second channel 211.

[0099] In some embodiments, a fixing part 2111 is provided in the second channel 211, and the fixing end of the abutment 230 is fixedly connected to the fixing part 2111. The connection method between the fixing end of the abutment 230 and the fixing part 2111 includes, but is not limited to, snap-fit, interference fit, threaded connection, etc.

[0100] For example, the fixing part 2111 is configured to form a threaded hole, and the fixing end of the abutment 230 is threadedly connected to the threaded hole, resulting in a stable and simple connection.

[0101] A second flow channel 2112 is formed between the fixing part 2111 and the inner wall of the second channel 211 to connect the second channels 211 at both ends of the fixing part 2111. For example, a plurality of second flow channels 2112 are provided at circumferential intervals along the fixing part 2111 to increase the total cross-sectional area of ​​the plurality of second flow channels 2112.

[0102] In some embodiments, the fixing portion 2111 is configured to form a second conical portion 2113 away from the first end of the abutment member 230, and the tip of the second conical portion 2113 is away from the abutment member 230. The second conical portion 2113 may be pyramidal or conical.

[0103] When the fluid flows from the first end of the second channel 211 toward the second end, the second conical part 2113 provided in the fixing part 2111 can disperse and guide the fluid to the second flow channel 2112, reducing local impact force.

[0104] Combination Figure 7 The female connector assembly 200 of this application embodiment may further include a second movable member 220, which is sealed and sleeved on the outside of the abutment member 230.

[0105] The second movable member 220 is provided with a sleeve hole 221 so that the second movable member 220 can be sleeved on the outer side of the abutting member 230. The second movable member 220 is sleeved on the abutting top of the abutting member 230.

[0106] A second sealing ring 320 is provided between the second movable member 220 and the abutment member 230 to seal the space between the second movable member 220 and the abutment member 230, thereby preventing fluid leakage from the space between the second movable member 220 and the abutment member 230.

[0107] For example, at least one of the second movable member 220 and the abutting member 230 is provided with a second sealing groove, and the second sealing ring 320 is disposed in the second sealing groove. This can limit the second sealing ring 320 and prevent the second sealing ring 320 from not returning to the position between the second movable member 220 and the abutting member 230 after the second movable member 220 moves.

[0108] In some embodiments, the second movable member 220 is sealed to the inner wall surface of the second channel 211. For example, a third sealing ring 330 is provided between the inner wall surfaces of the second movable member 220 and the second channel 211 to prevent fluid from leaking between the inner wall surfaces of the second movable member 220 and the second channel 211.

[0109] For example, at least one of the second movable member 220 and the abutting member 230 is provided with a third sealing groove, and a third sealing ring 330 is disposed in the third sealing groove. This can limit the position of the third sealing ring 330 and ensure the sealing function of the third sealing ring 330.

[0110] In this embodiment, the second movable member 220 is configured to move along the extension direction of the second channel 211, thereby allowing the second movable member 220 to switch between blocking the second channel 211 and opening the second channel 211.

[0111] When the male connector assembly 100 is separated from the female connector assembly 200, the second movable member 220 is elastically pressed against the abutment member 230 so that the second movable member 220 and the abutment member 230 block the second channel 211, thereby enabling the female connector assembly 200 to block the pipe it is connected to.

[0112] In some embodiments, at least a portion of the second movable member 220 is an elastic portion, such that the second movable member 220 is elastically pressed against the abutment member 230.

[0113] Continue to refer to Figure 7 In other embodiments, the female connector assembly 200 further includes a second elastic member 240. The second elastic member 240 is sleeved on the outside of the abutment member 230 and is configured to elastically press the second movable member 220 into the second channel 211.

[0114] The second elastic element 240 is compressed and restricted within the second channel 211, that is, the second elastic element 240 is a compression elastic element.

[0115] For example, the second elastic member 240 is sleeved on the outside of the abutment member 230, one end of the second elastic member 240 abuts against the second movable member 220, and the other end of the second elastic member 240 is fixed. For example, the other end of the second elastic member 240 is fixed to the abutment member; for another example, the other end of the second elastic member 240 is fixed to the fixing part 2111; for yet another example, the other end of the second elastic member 240 is fixed to the inner wall of the second channel 211.

[0116] In this embodiment, the other end of the second elastic member 240 abuts against the end of the fixed part 2111, which can not only achieve elastic compression of the second movable member 220, but also make the assembly of the second elastic member 240 simple.

[0117] The second elastic element 240 can be a spring, an elastic sleeve, or other structure capable of elastic deformation. In the accompanying drawings of the embodiments of this application, the second elastic element 240 is shown as a spring.

[0118] In this embodiment, the arrangement of the second elastic element 240 does not affect the conduction of the second channel 211. For example, the second elastic element 240 is a spring; or, for another example, the second elastic element 240 is an elastic sleeve.

[0119] Combination Figure 2 When the male connector assembly 100 and the female connector assembly 200 are engaged, a portion of the first body 110 is sealed and connected within the second channel 211. The first body 110 pushes the second movable member 220 toward the second end of the second channel 211 to make the second channel 211 open. The abutment member 230 pushes the first movable member 120 toward the first end of the first channel 111 to make the first channel 111 open. Thus, the first channel 111 and the second channel 211 are connected, thereby connecting the pipes at both ends.

[0120] With the above configuration, the female connector assembly 200 of this application embodiment forms a second channel 211 by providing a second body 210 for communicating with a pipeline; by sealing the second movable member 220 on the outside of the abutment member 230 and sealing the second movable member 220 with the inner wall of the second channel 211, the second channel 211 is blocked.

[0121] Furthermore, when the male connector assembly 100 and the female connector assembly 200 are engaged, a portion of the first body 110 is sealed to the second channel 211; the first body 110 pushes the second movable member 220 toward the second end of the second channel 211, thus opening the second channel 211; simultaneously, the abutment member 230 pushes the first movable member 120 toward the first end of the first channel 111, thus opening the first channel 111. In this way, the first channel 111 and the second channel 211 are connected, thereby connecting the pipes at both ends. Moreover, fluid can flow from the first channel 111 to the second channel 211, or from the second channel 211 to the first channel 111, without directional requirements for the use of the connector device.

[0122] When disassembly is required, the first body 110 can be removed from the second channel 211, which is simple and convenient. The connector device of this application embodiment has a simple structure. When separated, both ends can be sealed, and there is no need to arrange valves on the pipeline. When the connector device is assembled, the flow is bidirectional, and there is no directional requirement during installation, which helps to improve the flexibility of the connector device application.

[0123] Combination Figure 7 and Figure 8 In some embodiments, the abutment 230 includes a second connecting portion 231 and a second sealing portion 232. One end of the second connecting portion 231 is fixed inside the second channel 211, and the other end of the second connecting portion 231 is connected to the second sealing portion 232.

[0124] One end of the second connecting part 231 is fixedly connected to the fixing part 2111, and the other end of the second connecting part 231 can be integrally formed with the second sealing part 232, which not only makes the structure of the abutment 230 stable, but also reduces the assembly process of the female connector assembly 200.

[0125] When the male connector assembly 100 and the female connector assembly 200 are separated, the second movable member 220 is sealed to the outside of the second sealing portion 232. For example, a second sealing ring 320 is provided between the second movable member 220 and the second sealing portion 232.

[0126] like Figure 2 As shown, when the male connector assembly 100 and the female connector assembly 200 are engaged, the end of the second sealing part 232 away from the second connecting part 231 abuts against the first movable member 120, thereby pushing the first movable member 120 toward the first end of the first channel 111 and compressing the first elastic member 130.

[0127] The second movable member 220 moves to the second connecting part 231 and forms a second flow gap 233 between itself and the second connecting part 231, so that the second channel 211 is open.

[0128] Wherein, the diameter of the second connecting part 231 is smaller than the diameter of the second sealing part 232, the second movable member 220 is sealed to the second sealing part 232 to block the second channel 211; when the second movable member 220 and the second connecting part 231 are engaged, there is a gap between the second movable member 220 and the second connecting part 231 to form a second flow gap 233.

[0129] In this embodiment, the abutment 230 is sealed to the second movable member 220 by providing a second sealing part 232, thereby blocking the second channel 211. By providing a second connecting part 231, when the second movable member 220 moves to cooperate with the second connecting part 231, a second flow gap 233 can be formed between it and the second connecting part 231, allowing the second channel 211 to be open. Thus, by forming a second flow gap 233 between the second movable member 220 and the second connecting part 231, the sealing performance between the second movable member 220 and the inner wall of the second channel 211 can be guaranteed.

[0130] Combination Figure 9 In this embodiment, the second movable member 220 is configured to form a sleeve hole 221 so that the second movable member 220 is sealed and sleeved on the outside of the abutment member 230. A second sealing ring 320 is provided between the inner wall of the sleeve hole 221 and the second sealing portion 232 of the abutment member 230.

[0131] A third flow channel 223 is formed on the wall of the socket 221. The third flow channel 223 is configured to connect the portion of the second channel 211 toward the fixed end of the second connecting portion 231 and the portion of the socket 221 and the abutment 230 that are sealed together.

[0132] The second movable member 220 includes a first part and a second part connected together, arranged axially. The diameter of the first part is larger than the diameter of the second part. A third sealing ring 330 is provided between the first part and the inner wall of the second channel 211, and there is a gap between the second part and the inner wall of the second channel 211. Thus, the end of the first part facing the second part forms a limiting end face, which abuts against the second elastic member 240, thereby pressing the second movable member 220 against the abutting member 230 under the action of the second elastic member 240.

[0133] The third flow channel 223 has two ports. One port is located on the wall of the socket 221 and is located at the part where the socket 221 is sealed to the second sealing part 232 of the abutment member 230. The other port is located on the end face of the second movable member 220 facing the fixed part 2111. For example, the other port is located on the limiting end face of the first part, so that the third flow channel 223 enables the second channel 211 to be open.

[0134] In some embodiments, the socket 221 includes a first hole segment 2211 and a second hole segment 2212 that are connected to each other. The inner wall of the first hole segment 2211 is sealed to the second sealing part 232, and a second sealing ring 320 is provided between the inner wall of the first hole segment 2211 and the second sealing part 232.

[0135] When the male connector assembly 100 and the female connector assembly 200 are engaged, the second movable member 220 moves toward the first end of the second channel 211 under the action of the first body 110, thereby enabling the first hole section 2211 to engage with the second connecting part 231, and forming a second flow gap 233 between the inner wall of the first hole section 2211 and the second connecting part 231.

[0136] One port of the third flow channel 223 is located in the first hole section 2211, so that the third flow channel 223 is connected to the second flow gap 233, thereby making the second channel 211 conductive.

[0137] The second hole section 2212 cooperates with the second connecting part 231 to guide the first movable member 120 to move along the second channel 211.

[0138] When the male connector assembly 100 and the female connector assembly 200 are separated, the end wall of the second hole section 2212 facing the first hole section 2211 abuts against the second sealing part 232, so that the second movable member 220 and the abutting member 230 block the second channel 211.

[0139] In this embodiment, the socket 221 of the second movable member 220 is sealed to the second sealing portion 232 of the abutment member 230 by providing a first hole segment 2211. The second hole segment 2212 cooperates with the second connecting portion 231 to guide the movement of the second movable member 220. Furthermore, when the second movable member 220 moves toward the first end of the second channel 211, a gap exists between the first hole segment 2211 and the second connecting portion 231 to form a second flow gap 233. Thus, the second flow gap 233 can connect the third flow channel 223 and the second channel 211, allowing the second channel 211 to conduct.

[0140] In this embodiment of the application, a portion of the first body 110 extends into the second channel 211, making the first body 110 and the second body 210 detachably connected. This allows for both the assembly of the male connector assembly 100 and the female connector assembly 200 and their separation.

[0141] There are various ways to connect the first body 110 and the second body 210, such as snap-fit, threaded connection, flange connection, etc.

[0142] In this embodiment of the application, the first body 110 and the second body 210 are snapped together, making it convenient to assemble and disassemble the male connector assembly 100 and the female connector assembly 200, and simple to operate.

[0143] Combination Figure 2 and Figure 8 In some embodiments, the second body 210 is provided with an elastic latch 250; the first body 110 is provided with a mating groove 114.

[0144] When the male connector assembly 100 and the female connector assembly 200 are engaged, the elastic latch 250 engages with the mating groove to lock the male connector assembly 100 and the female connector assembly 200.

[0145] like Figure 8 As shown, a bayonet 214 is provided on the third shell portion 212 of the second body 210, and an elastic latch 250 is engaged on the third shell portion 212, with at least a portion of the elastic latch 250 extending into the interior of the second channel 211 through the bayonet 214.

[0146] The portion of the first body 110 with the mating groove 114 extends into the second channel 211, thereby engaging with the elastic latch 250 in the second channel 211, thus fixing the first body 110 and the second body 210 together.

[0147] The elastic latch 250 is open-loop shaped. Specifically, the elastic latch 250 includes two elastic arms, one end of which is connected, and the other end of which is spaced apart. The two elastic arms can elastically deform into the space.

[0148] At least a portion of the two elastic arms extend into the second channel 211 through the bayonet 214. When the two elastic arms elastically deform toward the gap, the elastic arms can disengage from the mating groove 114, thereby separating the second body 210 from the first body 110.

[0149] In this embodiment, a fourth sealing ring 340 is provided between the first body 110 and the inner wall of the second channel 211 to achieve a sealed connection between the first body 110 and the inner wall of the second channel 211. A fourth sealing groove is provided on at least one of the outer wall of the first body 110 and the inner wall of the second channel 211, and the fourth sealing ring 340 is disposed within the fourth sealing groove.

[0150] In this embodiment, the sealing connection between the first body 110 and the inner wall of the second channel 211 is located between the elastic buckle 250 and the abutment 230, that is, the fourth sealing ring 340 is located between the elastic buckle 250 and the second end of the first channel 111, ensuring the sealing of the connection between the first channel 111 and the second channel 211.

[0151] Continue to refer to Figure 2 and Figure 8 In some embodiments, the female connector assembly 200 further includes a limiting ring 260, which is fixed inside the second channel 211 and located between the fourth sealing ring 340 and the elastic latch 250. During assembly of the male connector assembly 100 and the female connector assembly 200, the first body 110 abuts against the limiting ring 260, limiting the first body 110 from extending into the second channel 211 and preventing excessive insertion. Furthermore, when the male connector assembly 100 and the female connector assembly 200 are separated, the limiting ring 260 also prevents the fourth sealing ring 340 from disengaging.

[0152] Through the above settings, combined with Figure 2 The accompanying drawings describe the fluid flow direction during assembly of the connector device in this application embodiment. The straight lines with arrows in the drawings indicate the fluid flow direction. The example given is that the fluid flows from the first end of the first channel 111 to the first end of the second channel 211. Of course, the fluid can also flow from the first end of the second channel 211 to the second end of the first channel 111.

[0153] The fluid flows from the first end of the first channel 111 to the first elastic member 130, then enters the first flow gap 122 through the first flow passage 1231 of the first movable member 120, and then enters the second channel 211 through the gap between the abutment member 230 and the inner wall of the first channel 111; then enters the third flow passage 223 of the second movable member 220 through the second flow gap 233 between the second movable member 220 and the abutment member 230; then flows to the first end of the second channel 211 through the second elastic member 240 and the second flow passage 2112.
