[0030] Various specific embodiments of the present invention will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "front," "rear," "upper," "lower," "left," and "right," are used herein to describe various exemplary structural parts and elements, their use is merely for ease of description and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed herein can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.
[0031] Figure 1A This is a perspective view of one embodiment of the connector assembly of this application. Figure 1B yes Figure 1A An exploded view of the connector assembly is provided to illustrate its structure. (See diagram below.) Figure 1A and Figure 1BAs shown, the connector assembly 100 includes a male connector 101 and a female connector 102. One end of the male connector 101 can be inserted into the female connector 102, and the other end is used to connect with a component or a first component (not shown). One end of the female connector 102 can accommodate the insertion end of the male connector 101, and the other end is used to connect with another component or a second component (not shown). The male connector 101 and the female connector 102 cooperate to controllably open or close the fluid passage between the first component and the second component. When the male connector 101 is separated from the female connector 102, the fluid in the first component and the second component is cut off by the male connector 101 and the female connector 102 respectively and cannot flow to the outside. When the male connector 101 is inserted into the female connector 102, the first component and the second component are in fluid communication through the male connector 101 and the female connector 102.
[0032] Figure 2 yes Figure 1A An exploded view of the male connector 101 shows the components included in the male connector 101. (See attached diagram.) Figure 2 As shown, the male connector 101 includes a male connector housing 201, a male connector elastic device 207, a male connector valve core 203, a male connector push rod 209, and a sealing element 208. The male connector elastic device 207 and the male connector valve core 203 are disposed inside the male connector housing 201, the sealing element 208 is sleeved on the outside of the housing 201, and the male connector push rod 209 is connected to the male connector housing 201. The male connector housing 201 includes a main body 212 and a cover 214, the main body 212 being generally cylindrical. During the assembly of the male connector 101, the male connector elastic device 207 and the male connector valve core 203 are first inserted into the main body 212, and then the cover 214 is connected to the main body 212, so that the male connector elastic device 207 and the male connector valve core 203 are located inside the male connector housing 201. The male connector housing 201 and the male connector push rod 209 are made of plastic materials, such as PA66-GF30, or PPA, PPS materials. The seal 208 is made of an elastic material, such as rubber.
[0033] Figure 3A yes Figure 2 Axial sectional view of the male connector housing 201 and the male connector push rod 209 in the image. Figure 3B yes Figure 3A The bottom view of the male connector housing 201 and the male connector push rod 209 shows their structure. (See attached image.) Figures 3A-3B As shown, the male connector housing 201 has an insertion end 310 and a first connection end 320. The first connection end 320 is used to connect with the first component, and the insertion end 310 is used to mate with the female connector 102.
[0034] The cover 214 of the male connector housing 201 is disposed at the first connecting end 320, and the male connector push rod 209 is connected to the insertion end 310 and extends in a direction away from the cover 214. As an example, the male connector push rod 209 is integrally formed with the body 212 of the male connector housing 201, and the body 212 and the cover 214 of the male connector housing 201 are separate components before the male connector 101 is assembled.
[0035] The main body 212 of the male connector housing 201 includes a cylindrical sidewall 316 and a cavity 315 enclosed by the sidewall 316, the cavity 315 forming a fluid channel 305 for the male connector. The main body 212 has a front end 321 and a rear end 322. The front end 321 forms an insertion end 310, and the rear end 322, together with the cover 214 connected to the rear end 322, forms a first connecting end 320. The main body 212 includes a front section 331, a middle section 332, and a rear section 333, wherein the front section 331 is close to the front end 321 of the main body 212, and the rear section 333 is rearward of the rear end 322 of the main body 212. The inner diameter of the front section 331 is smaller than the inner diameter of the rear section 333. The two ends of the middle section 332 are connected to the front section 331 and the rear section 333 respectively, thereby forming a tapered mating slope 341 on the inner wall of the middle section 332. The bevel 341 gradually moves away from the axis of the male connector 101 in the direction from the insertion end 310 of the male connector 101 to the first connection end 320. The bevel 341 is used to mate with the male connector valve core 203.
[0036] The male connector push rod 209 includes a first support portion 391 and three first rod portions 392. The first support portion 391 connects the three first rod portions 392 to the main body 212 of the male connector housing 201. The first support portion 391 includes a support ring 393 and a connecting foot 395. The connecting foot 395 extends outward from the outside of the support ring 393 to the inner wall of the male connector housing 201 and connects to the inner wall of the insertion end 310. The connection point between the connecting foot 395 and the male connector housing 201 can be located on the inner wall of the insertion end 310 or on the inner wall of the male connector housing 201 above the insertion end 310. The support ring 393 has a male connector hole 394 for allowing the female connector push rod to pass through. The male connector rod portions 392 extend from the support ring 393 in a direction away from the first connecting end 320 and beyond the insertion end 310. There are three male connector rod portions 392, and the three male connector rod portions 392 are evenly distributed along the circumferential direction.
[0037] The cover portion 214 includes a cover plate 351 and an inner flange 354 and an outer flange 355 located on the inner and outer sides of the cover plate 351, respectively. The cover plate 351 has a hole 352, and the inner flange 354 and the outer flange 355 extend around the hole 352, thereby forming a cover portion channel 357, which communicates with the male connector fluid channel 305. The outer flange 355 facilitates the connection of the male connector 101 with the first component, and the inner flange 354 facilitates the contact of the male connector elastic device 207 against the cover plate 351.
[0038] The insertion end 310 has an annular sealing groove 360 formed by recessing inward from the outer surface of the body 212 of the housing 201, for accommodating the seal 208.
[0039] Figure 4 yes Figure 2 An axial sectional view of the male connector valve core 203 of the male connector 101 shows the structure of the male connector valve core 203. (As shown...) Figure 4 As shown, the male connector valve core 203 includes a head 401 and a body 402, wherein the outer diameter of the head 401 is larger than the outer diameter of the body 402. The proximal end 441 of the head 401 is connected to the body 402, and the distal end 442 is used to connect to the male connector resilient device 207. The proximal end 441 of the head 401 is truncated conical, forming a sealing bevel 412 for engaging with a mating bevel 341. The sealing bevel 412 gradually moves away from the axis of the male connector valve core 203 in the direction from the proximal end 441 to the distal end 442 of the head. The distal end of the head 401 has a protrusion 413 for engaging with the male connector resilient device 207. The distal end of the body 402 has an inwardly recessed recess 415 that can partially accommodate the female connector push rod 709. In some embodiments, the male connector valve core 203 is integrally molded from a plastic material (e.g., PA66-GF30, or PPA, PPS type materials). In other embodiments, the male connector valve core 203 is first made of plastic material, and then a sealing layer is formed by an elastic material (e.g., rubber) at the position where the sealing slope 412 is formed at the head 401 of the valve core 203 through a secondary molding process. The sealing slope 412 is formed on the surface of the sealing layer, so that the sealing slope 412 has a certain elasticity and can better cooperate with the mating slope 341.
[0040] Figure 5 yes Figure 1A The axial sectional view of the male connector 101 shows the mating relationship of its components when the male connector 101 is in the closed position. For example... Figure 5As shown, the male connector elastic device 207 and the male connector valve core 203 are located within the cavity 315 of the housing 201. One end of the male connector elastic device 207 is fitted onto the inner flange 354 and abuts against the inner side of the cover plate 351 of the cover portion 214. The other end of the male connector elastic device 207 is fitted onto the protrusion 413 of the valve core and abuts against the head 401 of the male connector valve core 203. When the male connector elastic device 207 is compressed, the male connector valve core 203 is subjected to the elastic force of the male connector elastic device 207 and tends to move away from the cover portion 214, thereby causing the sealing slope 412 of the male connector valve core 203 to abut against the mating slope 341 of the housing 201. At this time, the male connector 101 is in the closed position, and the male connector fluid passage 205 is closed by the male connector valve core 203. In the closed position of the male connector 101, the distal end of the body 402 of the male connector valve core 203 is at least partially received in the male connector bore 394. The annular seal 208 is fitted over the exterior of the housing 201 and is at least partially located within the sealing groove 360 of the body 212 of the housing 201.
[0041] Figure 6 yes Figure 1A An exploded view of the female connector 102 shows the components included in the female connector 102. (See attached image.) Figure 6 As shown, the female connector 102 includes a female connector housing 601, a female connector elastic device 607, a female connector valve core 603, and a female connector push rod 709 (see [reference]). Figure 7A The female connector elastic device 607 and the female connector valve core 603 are disposed within the female connector housing 601, and the female connector push rod 709 is also disposed within the female connector housing 601 and connected to the female connector housing 601. The female connector housing 601 includes a main body 612 and a cover 614. During the assembly of the female connector 102, the female connector elastic device 607 and the female connector valve core 603 are first installed into the main body 612, and then the cover 614 is connected to the main body 612, so that the female connector elastic device 607 and the female connector valve core 603 are located inside the female connector housing 601. The female connector housing 601 and the female connector push rod 709 are made of plastic material, such as PA66-GF30 or PPA, PPS type materials.
[0042] Figure 7A yes Figure 6 Axial sectional view of the female connector housing 601 and the female connector push rod 709. Figure 7B yes Figure 7A A perspective view of the main body of the female connector housing 601 and the female connector push rod 709 shows the structure of the female connector housing 601 and the female connector push rod 709. (See attached image.) Figures 7A-7B As shown, the outer contour of the female connector housing 601 is approximately cylindrical, and it has a receiving end 710 and a second connecting end 720. The second connecting end 720 is used for connecting to the second component, and the receiving end 710 is used for mating with the male connector 101.
[0043] The female connector housing 601 includes a main body 612 and a cover 614, with the cover 614 disposed at the second connection end 720. A female connector push rod 709 is connected to the inner side of the main body 612 and extends toward the receiving end 710, but does not exceed the receiving end 710, thus the female connector push rod 709 is located inside the female connector housing 601. The female connector push rod 709 is integrally formed with the main body 612, and the main body 612 and the cover 614 are separate components before the female connector is assembled.
[0044] The main body 612 includes a cylindrical sidewall 616 and a cavity 715 enclosed by the sidewall 616, the cavity 715 forming a fluid channel 705 for the female connector. The main body 612 has a front end 721 and a rear end 722. The front end 721 constitutes a receiving end 710, and the rear end 722, together with a cover 614 connected to the rear end 722, constitutes a second connecting end 720. The main body 612 includes a plug-in section 730, a front section 731, a middle section 732, and a rear section 733, wherein the plug-in section 730 is close to the receiving end 710, the front section 731 is connected to the plug-in section 730, and the rear section 733 is close to the cover 614. The plug-in section 730 is used to accommodate the male connector 101. The inner diameter of the front section 731 is smaller than the inner diameter of the rear section 733, and the two ends of the middle section 732 are connected to the front section 731 and the rear section 733 respectively, thereby forming a mating inclined surface 741. The mating bevel 741 gradually approaches the axis of the female connector housing 601 in the direction from the receiving end 710 to the second connecting end 720. The mating bevel 741 is used to mate with the female connector valve core 603.
[0045] The female connector push rod 709 includes a second support portion 791 and a second rod portion 792. The second support portion 791 connects the second rod portion 792 to the female connector housing 601. The second support portion 791 includes three connecting feet 795, which extend outward from the outer side of one end of the rod portion 792 to the inner wall of the female connector housing 601 and connect with the inner wall of the female connector housing 601. The connection points of the three connecting feet 795 with the female connector housing 601 are located on the inner wall of the insertion section 730 and / or the front section 731 of the female connector housing 601. Adjacent connecting feet 795, rod portions 792, and the inner wall of the female connector housing 601 form a female connector hole 794. The radial cross-sectional area of the female connector hole 794 is larger than the radial cross-sectional area of the first rod portion 392, so that the male connector push rod 209 can pass through the female connector hole 394. Thus, in the radial direction of the connector assembly, the first rod portion 392 is arranged around the second rod portion 792, that is, the first rod portion 392 and the second rod portion 792 are staggered. The rod portion 792 of the female connector push rod extends from the second support portion 791 in a direction away from the second connecting end 720 to the end face near the receiving end 710, but does not exceed the end face of the receiving end 710, that is, the female connector rod portion 792 is entirely located inside the female connector housing 601. The outer diameter of the female connector rod portion 792 is smaller than the inner diameter of the male connector hole 394, so that the female connector rod portion 792 can pass through the male connector hole 394. The female connector rod portion 792 has a groove 797 formed by recessing from the end face of the female connector rod portion 792 near the second support portion 791 into the female connector rod portion 792, and the groove 797 is used to partially receive the female connector valve core 603.
[0046] exist Figure 7A In the illustrated embodiment, the female connector push rod 609 is located inside the female connector housing 601. In another embodiment of this application, the female connector push rod may also extend out of the receiving end of the female connector housing.
[0047] The cover portion 614 includes a cover plate 751 and an inner flange 754 and an outer flange 755 located on the inner and outer sides of the cover plate 751, respectively. The cover plate 751 has a hole 752, and the inner flange 754 and the outer flange 755 extend around the hole 752, thereby forming a cover portion channel 757, which communicates with the fluid channel 705 of the female connector. The outer flange 755 facilitates the connection of the female connector 102 with the second component, and the inner flange 754 facilitates the abutment of the elastic device 607 of the female connector against the cover plate 751.
[0048] Figure 8 yes Figure 6 An axial sectional view of the female connector valve core shows the structure of the female connector valve core 603. (As shown...) Figure 8As shown, the female connector valve core 603 includes a head 801 and a pin 802, wherein the pin 802 extends outward from the proximal end of the head 801. The proximal end of the head 801 forms a truncated cone shape, thereby forming a sealing bevel 812 for engaging with the mating bevel 741. The sealing bevel 812 gradually moves away from the axis of the female connector valve core 603 in the direction from the proximal end to the distal end of the head. In some embodiments, the female connector valve core 603 is integrally molded from a plastic material (e.g., PA66-GF30, or PPA, PPS type materials). In other embodiments, the female connector valve core 603 is first made of a plastic material, and then a sealing layer is formed from an elastic material (e.g., rubber) at the proximal end of the head 801 where the sealing surface 812 is formed through a secondary molding process. The surface of the sealing layer is the sealing bevel 812, so that the sealing bevel 812 has a certain elasticity and can better engage with the mating bevel 341. The distal end of the head 801 has an outwardly protruding convex portion 813 for engaging with the elastic device 607 of the female connector. The shape of the pin portion 802 matches the shape of the groove 797 on the rod portion 792 of the female connector, so that the pin portion 802 can be at least partially received in the groove 797 and move within the groove 797.
[0049] Figure 9 This is an axial sectional view of the female connector 102, showing the mating relationship of its components when the female connector 102 is in the closed position. For example... Figure 9 As shown, the female connector elastic device 607 and the female connector valve core 603 are disposed in the housing 601. One end of the female connector elastic device 607 is sleeved on the inner flange 754 and abuts against the inner side of the cover plate 751 of the cover portion 614. The other end of the female connector elastic device 607 is sleeved on the protrusion 813 of the female connector valve core 603 and abuts against the head 801 of the female connector valve core 603. When the female connector elastic device 607 is compressed, the female connector valve core 603 is subjected to the elastic force of the female connector elastic device 607 and tends to move away from the cover portion 614, so that the sealing slope 812 of the female connector valve core 603 abuts against the mating slope 741 of the housing 601. At this time, the female connector valve core 603 is in the closed position, and the female connector fluid passage 705 is closed. The pin portion 802 of the female connector valve core 603 is inserted into the groove 797, so that the female connector valve core 603 cannot move arbitrarily in the radial direction.
[0050] Figure 10A This is an axial sectional view of the male connector 101 and the female connector 102 when they are separated. Figure 10B This is an axial sectional view of the male connector partially inserted into the female connector. Figure 10C This is an axial sectional view of the male connector when it is fully inserted into the female connector. Figures 10A-10C The process of inserting the male and female connectors is shown.
[0051] like Figures 10A-10C As shown, when the male connector 101 and the female connector 102 are plugged in, as... Figure 10A As shown, first align the insertion end 310 with the receiving end 710, then move the female connector 102 toward the male connector 101, so that the insertion end 310 gradually enters the receiving end 710 until it reaches the desired position. Figure 10B The pre-installation position is shown. Next, the female connector 102 is moved toward the male connector 101, and a thrust is applied to the female connector 102. This thrust causes the female connector 102 to overcome the elastic forces of the male connector elastic device 207 and the female connector elastic device 607, moving to the position shown. Figure 10C The working position shown opens the male connector fluid channel 305 and the female connector fluid channel 705, and the male connector 101 and the female connector 102 are in fluid communication.
[0052] Specifically, such as Figure 10A As shown, when the male connector 101 and the female connector 102 are separated, the male connector valve core 203 is in the closed position. The sealing slope 412 of the male connector valve core 203 abuts against the mating slope 341 of the male connector housing 201, thereby blocking the fluid passage 305 and closing it. The fluid in the first component connected to the male connector 101 is blocked by the valve core 203 and cannot reach the insertion end 310. Similarly, the female connector valve core 603 is in the closed position, and the sealing slope 812 of the female connector valve core 603 abuts against the mating slope 741 of the female connector housing 601, thereby blocking the fluid passage 705 and closing it. The fluid in the second component connected to the female connector 102 is blocked by the female connector valve core 603 and cannot reach the receiving end 710.
[0053] like Figure 10B As shown, the male connector 101 is partially inserted into the female connector 102 to the pre-installation position. Because the male connector push rod 209 and the female connector push rod 709 are offset in the radial direction of the connector assembly, the male connector 101... Figure 10A During the movement from the indicated position to the pre-installation position, the male connector push rod 209 passes through the female connector hole 794 and contacts the head 801 of the female connector valve core 603, while the distal end of the female connector push rod 709 enters the recess 415 of the male connector valve core 203 and contacts the bottom of the recess 415. In the pre-installation position, although the insertion end 310 is partially inserted into the receiving end 710, both the male connector valve core 203 and the female connector valve core 603 remain in the closed position.
[0054] like Figure 10CAs shown, when the male connector 101 is inserted into the female connector 102 and reaches the working position, an external force causes the male connector push rod 209 to overcome the elastic force of the female connector elastic device 607, and pushes the female connector valve core 603 downward, causing the sealing slope 812 to leave the mating slope 741 of the female connector housing 601. At this time, the female connector fluid passage 705 is opened, the female connector 102 is in the open position, and fluid can flow through the space between the sealing slope 812 and the mating slope 741. Simultaneously, the external force also causes the female connector push rod 709 to overcome the elastic force of the male connector elastic device 207, and pushes the male connector valve core 203 upward, causing the sealing slope 412 to leave the mating slope 341 of the male connector housing 201. At this time, the male connector fluid passage 305 is opened, the male connector 101 is in the open position, and fluid can flow through the space between the sealing slope 412 and the mating slope 341. Since both the male connector fluid channel 305 and the female connector fluid channel 705 are open, the first component connected to the male connector 101 and the second component connected to the female connector 102 are in fluid communication through the male connector fluid channel 305 and the female connector fluid channel 705.
[0055] When it is necessary to separate the first component and the second component, the male connector 101 is pulled out of the female connector 102. The male connector valve core 203 and the female connector valve core 603 return to their respective closed positions due to the action of the male connector elastic device 207 and the female connector elastic device 607, so that the fluid in the first component and the second component will not leak into the external environment.
[0056] In the specific application of the connector assembly, there are two application environments. In the first application environment, after the first and second components are interconnected through the connector assembly, their installation positions are limited by the installation environment and cannot be moved. Furthermore, the male connector 101 and female connector 102 are directly and fixedly connected to the first and second components respectively, thus limiting the male connector 101 and female connector 102 to their working positions and preventing them from moving relative to each other. In the first application environment, no limiting device is needed between the male and female connectors to restrict their movement relative to each other. Figure 1A-10B The illustrated embodiment is applicable to the first application environment. In the second application environment, the male connector 101 and the female connector 102 are respectively connected to the first component and the second component via hoses, or the first component and the second component can still move relative to each other after being connected to each other via the connector assembly. For the second application environment, a limiting device needs to be provided between the male connector 101 and the female connector 102 so that when the male connector and the female connector are installed in place, the male connector and the female connector cannot move relative to each other, so that the connector assembly 100 can be held in the working position.
[0057] Figure 11This is an axial sectional view of another embodiment of the connector assembly of this application, which is suitable for the second application environment described above. Figure 11 The illustrated embodiments and Figure 1A The embodiments shown are similar, except that, in Figure 11 In the illustrated embodiment, the outer side of the insertion end 1110 has an inwardly recessed limiting recess 1118, and the inner side of the receiving end 1120 has an outerly and innerly protruding limiting protrusion 1119. When the male connector 1101 is inserted into the female connector 1102 and reaches the working position of the connector assembly 1100, the limiting protrusion 1119 enters the limiting recess 1118. Therefore, after the male and female connectors are installed in place, the male and female connectors cannot move relative to each other, and the connector assembly 1100 can remain in the working position. Figure 11 This is an example of a connector assembly with a limiting structure. The limiting structure can also take other forms, such as clips on the outside of the male and female connectors. The key is to ensure that the male and female connectors remain in the working position of the connector assembly.
[0058] In one embodiment of this application, the lengths of the male connector push rod 209 and the female connector push rod 709 are configured such that when the male connector 101 and the female connector 102 reach such... Figure 10B In the pre-installation position shown, the male connector push rod 209 and the female connector push rod 709 are in contact with the female connector valve core 603 and the male connector valve core 203, respectively. This allows the female connector valve core 603 and the male connector valve core 203 to move simultaneously when an external force is applied, thereby opening the male connector fluid passage 305 and the female connector fluid passage 705. Furthermore, the connector assembly of this application is also configured such that, as... Figure 10C In the working position shown, there is a certain distance between the female connector valve core 603 and the female connector cover 614, and a certain distance between the male connector valve core 203 and the male connector cover 214, so that there is a large flow space between the female connector valve core 603 and the female connector cover 614, and between the male connector valve core 203 and the male connector cover 214, so that the resistance of the fluid flowing through the male connector 101 and the female connector 102 is in a relatively small range.
[0059] In one application of this application, the male connector 101 is connected to the vehicle body and communicates with the coolant in the vehicle body. The female connector 102 is connected to the battery used in the vehicle and communicates with the coolant in the battery. When the battery needs to be installed on the vehicle body, the male connector 101 and the female connector 102 are connected to put it in the working position, so that the coolant in the vehicle body and the coolant in the battery are in fluid communication, forming a closed circulation system to continuously cool the battery. When the battery is removed from the vehicle body, the male connector 101 and the female connector 102 are disconnected, and the coolant will not leak into the external environment.
[0060] The male connector 101 and female connector 102 in this application only include corresponding housings, push rod valve cores, and elastic devices, resulting in a simple connector assembly structure with fewer components, making it easy to manufacture. The male connector push rod 209 is integrated into the male connector housing 201, forming an integral part with the male connector 101, and the female connector push rod 709 is integrated into the female connector housing 601, forming an integral part with the female connector housing 601. This further reduces the number of components in the connector assembly, reducing assembly steps in the manufacturing process and improving assembly efficiency. The male connector valve core 203 in this application has a recess 415 for partially accommodating the female connector push rod 709 to limit the relative position of the male connector valve core 203 during movement. The female connector push rod 709 has a groove 797 for partially accommodating the female connector valve core 603 to limit the relative position of the female connector valve core 603 during movement. Therefore, during the connection and disconnection operations of the connector assembly, the male connector valve core 203 and the female connector valve core 603 are restricted by the female connector push rod 709 and can only move in the axial direction. This makes it difficult for the male connector valve core 203 and the female connector valve core 603 to deviate during the movement, so as to ensure the fit between the sealing slope and the mating slope.
[0061] Furthermore, in this application, the male connector 101 and the female connector 102 are sealed by sealing bevels and mating bevels on the male connector housing and the female connector housing, respectively. The fit between the bevels can be very tight, resulting in a good sealing effect. Specifically, the sealing bevels 412 and 812 of the male and female connectors are formed by the male connector valve core 203 and the female connector valve core 603, respectively, and the mating bevels 341 and 741 are formed by the inner walls of the male connector housing 201 and the female connector housing 601, respectively. The male connector valve core 203 is subjected to a thrust applied by the male connector elastic device 207, and the sealing bevel 412 gradually contracts in the direction of the thrust (i.e., gradually approaches the axis). The mating bevel 341 and the sealing bevel 412 are form-fitted, thereby pressing the sealing bevel 412 against the mating bevel 341. Similarly, the female connector valve core 603 is subjected to the thrust applied by the female connector elastic device 607. The sealing bevel 812 gradually contracts in the direction of the thrust (i.e., gradually approaches the axis), and the mating bevel 741 and the sealing bevel 812 are form-fitted, thereby pressing the sealing bevel 812 onto the mating bevel 741. Through the above arrangement, the male connector valve core 203 and the female connector valve core 603 provide a good seal for the male connector 101 and the female connector 102 with a simple structure.
[0062] Although only some features of this application have been illustrated and described herein, many modifications and variations will be apparent to those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such modifications and variations that fall within the essential spirit and scope of the invention.
