[0037] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0038] Figures 1A-1D The overall structure of a connector assembly 100 according to an embodiment of the present application is shown, wherein Figure 1A is a perspective view of the connector assembly 100, Figure 1B is an exploded view of the connector assembly 100, Figure 1C yes Figure 1A A front view of the connector assembly in Figure 1D yes Figure 1A Assembly process diagram of the connector assembly in .

[0039] like Figures 1A-1C The connector assembly 100 includes a female connector 110, a male connector 120, a sealing ring 150, a limiting ring 160 and a latch 180. The female connector 110 receives at least a portion of the male connector 120 and is fixedly connected to the male connector 120 through the latch 180. The latch 180 is, for example, a U-shaped elastic clip. The sealing ring 150 is sleeved on the male connector 120 and is clamped between the female connector 110 and the male connector 120 to seal the female connector 110 and the male connector 120. The limiting ring 160 is used to limit the sealing ring 150.

[0040] like Figure 1D As shown, during assembly, the sealing ring 150, the limiting ring 160 and the latch 180 are first installed in or on the female connector 110, and then the male connector 120 is inserted into the female connector 110 to achieve a fixed connection between the two.

[0041] The connector assembly 100 of the present application has two flow channels, including a connector assembly inlet flow channel 510 and a connector assembly outlet flow channel 520 (eg, Figure 5AThat is, the present application uses one connector assembly to simultaneously realize the two functions of inputting and outputting fluids, without the need to use two separate connector assemblies to realize these two functions. To this end, the male connector 120 and the female connector 130 of the connector assembly 100 each also have two flow channels, one for input and one for output. As an example, the male connector 120 can be a pipe on an exhaust box of a vehicle's cooling system, which has the functions of both an inlet pipe and an outlet pipe, and only one tubular member is needed to realize the two functions of fluid input connection and fluid output connection.

[0042] Figure 2A-2C The specific structure of the male connector 120 is shown, wherein: Figure 2A is a perspective view of the male connector 120, Figure 2B yes Figure 2A A left side view of the male connector 120 in FIG. Figure 2C yes Figure 2B A cross-sectional view of the male connector 120 along line AA. Figure 2A-2C As shown, the male connector 120 includes a male connector housing 210, which is generally tubular. The male connector 120 also includes a male connector partition 230, which is disposed in the male connector housing 210 and partitions a male connector inlet flow channel 223 and a male connector outlet flow channel 225 in the male connector housing 210. The male connector inlet flow channel 223 and the male connector outlet flow channel 225 are arranged side by side in the radial direction of the male connector housing 210.

[0043] In the embodiment shown in the figure, the male connector housing 210 defines a cylindrical cavity, and the male connector partition 230 is generally plate-shaped and arranged along the axial direction of the male connector housing 210, thereby dividing the cavity defined by the male connector housing 210 into two along the axial direction. In some embodiments, the male connector partition 230 is arranged radially centered in the cavity of the male connector housing 210. The male connector partition 230 can be formed integrally with the male connector housing 210, or can be fixedly connected to the male connector housing 210 in other ways.

[0044] The male connector 120 further includes a guide portion 250 disposed on the male connector housing 210 for engaging with a guide mating portion 350 (see FIG. Figure 3B ) so that the male connector housing 210 is inserted into the female connector housing 310 in a predetermined orientation (or direction) in the rotation direction around its axis. In the embodiment shown in the figure, the guide portion 250 is a protrusion protruding outward from the outer surface of the male connector housing 210. Two such guide portions 250 are provided on the male connector housing 210. The two guide portions 250 are symmetrically arranged relative to the axis position of the male connector housing 210 and are respectively adjacent to the two opposite radial ends of the male connector partition 230.

[0045] The male connector 120 further includes a locking groove 219 disposed on the male connector housing 210 for receiving the latch 180. The locking groove 219 is formed by being recessed inward from the outer surface of the male connector housing 210 and extending along the circumference of the male connector housing 210 to form an annular groove.

[0046] The male connector housing 210 includes a proximal end ( Figure 2A The left end of the Figure 2A ), and has a proximal surface 215 located at the proximal end. The outer surface of the male connector housing 210 includes three sections, namely, a first section 211 close to the proximal end, a second section 212 close to the distal end, and a third section 213 located between the first section 211 and the second section 212. The first section 211 and the second section 212 are cylindrical, and the diameter of the first section 211 is smaller than the diameter of the second section 212. The third section 213 connects the first section 211 and the second section 212, and is generally truncated cone-shaped. The locking groove 219 and the guide portion 250 are both provided on the second section 212. The sealing ring 150 is sleeved on the first section 211, and the limiting ring 160 is sleeved on the third section 213. The truncated cone shape of the third section 213 limits the axial movement of the sealing ring 150 and the limiting ring 160 in the male connector housing 210.

[0047] like Figure 2A and 2C As shown, the male connector partition 230 has a male connector partition proximal surface 235 near the proximal end of the male connector housing 210, and the male connector partition proximal surface 235 is indented inwardly relative to the male connector housing proximal surface 215, so as to be located in the male connector housing 210. In addition, the inner surface of the male connector housing 210 is in a bell-mouth shape that expands outward near the proximal end of the male connector housing 210, so that the radial sealing portion 410 of the flow dividing seal 390, which will be described later, is easier to insert into the male connector housing 210.

[0048] Figure 3A and 3B The specific structure of the female connector 110 is shown, wherein: Figure 3A is a top view of the female connector 110, Figure 3B 1 is an axial cross-sectional view of the female connector 110. Figure 3B As shown, the female connector 110 includes a female connector housing 310, a female connector partition 340 and a diverter seal 390, and the female connector partition 340 and the diverter seal 390 are arranged in the female connector housing 310, so that Figure 3A Not visible in.

[0049] like Figure 3A and 3BAs shown, the female connector housing 310 includes an inlet section 313, an outlet section 315 and a connecting section 312, each of which is generally tubular. The connecting section 312 includes an opposite first end 321 and a second end 323, the inlet section 313 and the outlet section 315 are connected to the first end 321 of the connecting section 312, and the male connector 120 is connected to the female connector housing 310 via the second end 323 of the connecting section 312.

[0050] More specifically, the inlet section 313 and the outlet section 315 are formed by a straight tube 360, which extends substantially perpendicularly (or transversely) to the axial direction of the connecting section 312. The straight tube 360 ​​includes a communication port 370, which passes through the tube wall of the straight tube 360 ​​to connect the straight tube 360 ​​with the connecting section 312. The female connector housing 310 is a three-way tube structure as a whole when viewed from the outside, and includes three ports, which are respectively formed by the inlet section 313, the outlet section 315 and the connecting section 312.

[0051] like Figure 3B As shown, the female connector partition 340 of the female connector 110 is disposed in the straight tube 360, and extends transversely to the axial direction of the straight tube 360, and is used to separate the straight tube 360 ​​into the above-mentioned inlet section 313 and outlet section 315. In the embodiment shown in the figure, the female connector partition 340 has an extension portion 345 extending from the communication port 370 into the connecting section 312. The connecting section 312 has a first end opening 327 at the first end 321, and the communication port 370 of the straight tube 360 ​​is smaller than the first end opening 327, so as to form a step surface 380 between the communication port 370 and the first end opening 327. The extension portion 345 of the female connector partition 340 extends beyond the step surface 380. The female connector partition 340 is also generally plate-shaped, and has substantially the same thickness as the male connector partition 230.

[0052] The flow divider seal 390 is used to seal and fluidly connect the inlet section 313 and the outlet section 315 of the female connector 110 to the male connector inlet flow channel 223 and the male connector outlet flow channel 225 of the male connector 120, respectively, to form a mutually separated connector assembly inlet flow channel 510 and a connector assembly outlet flow channel 520. In the embodiment shown in the figure, the flow divider seal 390 is retained in the female connector housing 310 by the extension 345 of the female connector partition 340.

[0053] It is worth noting that although in the illustrated embodiment, the inlet section 313 and the outlet section 315 are formed by a straight tube 360 ​​extending substantially perpendicular to the axial direction of the connecting section 312, in other embodiments, the straight tube 360 ​​can be configured to form a non-90-degree angle with the axial direction of the connecting section 312, or the inlet section 313 and the outlet section 322 can be formed by a bent tube, or the inlet section 313, the outlet section 315 and the connecting section 312 can be respectively formed by three sections of tubes, and the three sections of tubes are interconnected to form a Y shape or other shapes.

[0054] Figures 4A-4C The specific structure of the diverter seal 390 is shown, wherein: Figure 4A is a perspective view of the diverter seal 390 viewed from the front to the rear, Figure 4B is a perspective view of the diverter seal 390 viewed from the rear to the front, Figure 4C 3 is a radial cross-sectional view of the flow dividing seal 390. The flow dividing seal 390 is formed integrally from an elastic rubber material. Figures 4A-4C As shown, the flow dividing seal 390 includes a radial sealing portion 410 and a circumferential sealing portion 420. The circumferential sealing portion 420 is arranged around the radial sealing portion 410, and the radial sealing portion 410 is connected to the circumferential sealing portion 420 through the opposite ends 411 in the length direction thereof. The radial sealing portion 410 includes end sealing surfaces 413 located at the opposite ends 411 thereof, and a radial sealing surface 415 connecting the end sealing surfaces 413. The radial sealing portion 410 forms a cavity 418, and receives the extension portion 345 of the female connector partition 340 through the cavity 418. The size of the cavity 418 is designed to be slightly smaller than the size of the female connector partition 340, so that the radial sealing portion 410 is wrapped around the female connector partition 340 to be retained in the female connector housing 310 through the female connector partition 340.

[0055] like Figure 4C As shown, the circumferential sealing portion 420 is bent rightward (toward the radial sealing surface 415 of the radial sealing portion 410) in the middle portion in the radial direction, so the cross section of the circumferential sealing portion 420 is curved. When the female connector 110 receives the male connector 120, the circumferential sealing portion 420 protrudes toward the male connector 120.

[0056] Figure 5A and 5B 1 shows the mating relationship between the female connector 110 and the male connector 120 when the female connector 110 receives and fixes the male connector 120. Figure 5A yes Figure 1C A cross-sectional view of the connector assembly 100 along line BB, Figure 5B yes Figure 1C A cross-sectional view of the connector assembly along line CC. Figure 5A and 5BAs shown, when the female connector 110 receives and fixes the male connector 120, the male connector 120 is located in the connecting section 312 of the female connector housing 310, and the extension 345 of the female connector partition 340 and the radial sealing portion 410 of the flow dividing seal 390 retained thereon at least partially extend into the male connector housing 210. In addition, the female connector partition 340 is aligned with the male connector partition 230 so that the two appear to extend continuously. The radial sealing portion 410 of the flow dividing seal 390 is clamped between the male connector partition 230 and the female connector partition 340, and its radial sealing surface 415 abuts the male connector partition 230. In addition, the two end sealing surfaces 413 of the radial seal 410 abut the inner surface of the male connector housing 210. The circumferential sealing portion 420 of the flow dividing seal 390 is clamped between the male connector housing proximal surface 215 of the male connector 120 and the step surface 380 of the female connector housing 310. Thus, the circumferential seal portion 420 seals and connects the male connector housing 210 to the communication port 370 , and the radial seal portion 410 seals and connects the female connector partition portion 340 to the male connector partition portion 230 .

[0057] Thus, the connection between the inlet section 313 of the female connector 110 and the inlet flow channel 223 of the male connector is provided with a flow divider seal, and the connection between the outlet section 315 of the female connector 110 and the outlet flow channel 225 of the male connector is also provided with a flow divider seal. Thus, via the flow divider seal 390, the inlet section 313 and the outlet section 315 of the female connector 110 are respectively in sealed fluid communication with the male connector inlet flow channel 223 and the male connector outlet flow channel 225 of the male connector 120, so as to form a connector assembly inlet flow channel 510 and a connector assembly outlet flow channel 520 separated from each other.

[0058] The male connector 120 of the present application having two flow channels (inlet flow channel 223 and outlet flow channel 225) can be set on the exhaust box of the cooling system of the vehicle, for example, as a pipe for forming the inlet and outlet of the exhaust box. The female connector 130 of the present application can be used to connect the inlet flow channel 223 and the outlet flow channel 225 in the male connector 120 on the exhaust box with other pipelines respectively, so that the exhaust box can be connected to the cooled vehicle parts via the connector assembly inlet flow channel 510 and the connector assembly outlet flow channel 520 to form a cycle, so that the cooling liquid can flow out of the exhaust box to the cooled vehicle parts, and can flow back to the exhaust box for exhaust.

[0059] Compared with two separate inlet and outlet pipes, since only one male connector is provided as a pipe, not only can the shape of the exhaust box be made simpler, but also the connection operation between the exhaust box and the external pipeline is simplified. The female connector of the present application can be used in conjunction with the above-mentioned pipe to form a connector assembly with both input and output flow channels. The female connector of the present application has a simple structure, is easy to manufacture, and is easy to assemble. In addition, the diverter seal of the present application enables the two flow channels in the female connector and the two flow channels in the male connector (pipe) to be sealed and connected respectively, and the two flow channels formed after the connection are also separated from each other, thereby being able to meet the use scenario where the two flow channels need to be separated from each other.
