[0061] The locking fastener 250 is sleeved on the third mating part 211 of the second core 210. The third mating part 211 passes through the receiving cavity 251 and the sleeve hole 2511 in sequence. Since the diameter of the second intermediate part 212 is larger than the diameter of the sleeve hole 2511, the second intermediate part 212 cannot pass through the sleeve hole 2511. The second intermediate part 212 abuts against the locking surface 2514.

[0062] The second rubber coating 260 covers the third mating part 211 of the second air tube 230, the second air needle 240, and the second rubber core 210. When the second rubber coating 260 covers the third mating part 211, the second rubber coating 260 partially squeezes into the multiple second water-stop grooves 2111 of the third mating part 211, which helps to improve the stability of the connection between the second rubber coating 260 and the second rubber core 210 and improves the sealing effect between the second rubber coating 260 and the second rubber core 210.

[0063] In this embodiment, please refer to Figure 13 and Figure 14 The first connector 100 is inserted into the second connector 200, the first terminal 120 is adapted to the second terminal 220, and the first channel 1122 is connected to the second channel 2122. Specifically, the fourth mating part 213 of the second core 210 is inserted into the insertion cavity 1131 of the second mating part 113. The end face of the fourth mating part 213 facing away from the third mating part 211 sealably abuts against the side of the sealing gasket 150 facing away from the bottom surface of the insertion cavity 1131 and the boss 1132. The first channel 1122 is opposite to and connected to the second channel 2122. At the same time, the first insertion part 1211 of the first power terminal 121 is inserted into the third insertion part 2211 of the second power terminal 221, and the second insertion part 1221 of the first signal terminal 122 is inserted into the fourth insertion part 2221 of the second signal terminal 222 to achieve electrical connection. After the first connector 100 and the second connector 200 are plugged in, the locking fastener 250 is rotated along the axial direction of the locking fastener 250 so that the internal thread of the locking fastener 250 is connected to the external thread of the first rubber core 110, making the connection between the first connector 100 and the second connector 200 more stable.

[0064] It is understood that the end face of the first core 110 facing the second core 210 is provided with a insertion cavity 1131, and the bottom surface of the insertion cavity 1131 is provided with a boss 1132. The boss 1132 is opposite to the second channel 2122. One end of the first channel 1122 facing the second channel 2122 passes through the boss 1132 along the X-axis direction, and the other end of the first channel 1122 passes through the surface of the first core 110 away from the insertion cavity 1131.

[0065] In this embodiment, by providing a first channel 1122 and a first terminal 120 in the first connector 100, and a second channel 2122 and a second terminal 220 in the second connector 200, when the first connector 100 and the second connector 200 are connected, the first channel 1122 and the second channel 2122 are connected, and the first terminal 120 and the second terminal 220 are adapted to each other. The connector 1000 can transmit media such as gas or liquid through the first channel 1122 and the second channel 2122. At the same time, the connector 1000 can also transmit power and / or signals through the two terminals, making the connector 1000 more functional. The design of the first channel 1122 being directly disposed on the first core 110 and the second channel 2122 being directly disposed on the second core 210 results in a simple structure and lower cost for the connector 1000.

[0066] In this embodiment, by providing a sealing gasket 150, the sealing gasket 150 can seal the gap between the fourth mating part 213 and the bottom surface of the insertion cavity 1131, preventing gas or liquid in the channel from flowing from the gap to the power terminal and signal terminal, avoiding damage to the power terminal and signal terminal, and helping to improve the life of the connector 1000.

[0067] In this embodiment, when the fourth mating part 213 is inserted into the insertion cavity 1131, the fourth mating part 213 will continuously compress the sealing gasket 150. When the fourth mating part 213 abuts against the boss 1132, the fourth mating part 213 stops compressing the sealing gasket 150 to prevent excessive compression of the sealing gasket 150, which is beneficial to improving the service life of the sealing gasket 150 and thus ensuring that the connector 1000 has a good sealing effect for a long time.

[0068] In other embodiments, the boss 1132 may be omitted, one end of the first channel 1122 passes through the bottom surface of the insertion cavity 1131, one end of the second core 210 is inserted into the insertion cavity 1131, and the second core 210 is sealed against the sealing gasket 150. The first channel 1122, the mating hole 151 and the second channel 2122 are interconnected.

[0069] In this embodiment, a first air needle 140 is designed, with one end positioned at the end of the first channel 1122 away from the second channel 2122, and the other end of the first air needle 140 connected to one end of the first air tube 130, facilitating the connection between the first air tube 130 and the first channel 1122. A second air needle 240 is also designed, with one end positioned at the end of the second channel 2122 away from the first channel 1122, and the other end of the second air needle 240 connected to one end of the second air tube 230, facilitating the connection between the second air tube 230 and the second channel 2122.

[0070] In this design, one of the outer peripheral surface of the first air needle 140 and the inner peripheral surface of the first channel 1122 is provided with a first limiting boss 1123, and the other is provided with a first limiting groove 1431. The design of the first limiting boss 1123 being positioned in the first limiting groove 1431 is beneficial to improving the stability of the connection between the first air needle 140 and the first adhesive core 110. Similarly, one of the outer peripheral surface of the second air needle 240 and the inner peripheral surface of the second channel 2122 is provided with a second limiting boss 2123, and the other is provided with a second limiting groove 2431. The design of the second limiting boss 2123 being positioned in the second limiting groove 2431 is beneficial to improving the stability of the connection between the second air needle 240 and the second adhesive core 210.

[0071] Please refer to Figure 15 , Figure 16 and Figure 17 The connector 1000 provided in the second embodiment of this application differs from that in the first embodiment in that the locking fastener 250 is connected to the first adhesive core 110 and the second adhesive core 210 in a different way. Specifically, the first adhesive core 110 is provided with a first slot 1133 and a first guide groove 1134. The first slot 1133 is disposed on the outer peripheral surface of the second mating part 113, and the first slot 1133 is an elongated arc shape, with its length extending along the circumference of the second mating part 113. The first guide groove 1134 is disposed on the outer peripheral surface of the second mating part 113, with one end of the first guide groove 1134 communicating with the first slot 1133, and the other end of the first guide groove 1134 passing through the end face of the second mating part 113 away from the first mating part 111. Preferably, the bottom surface of the first slot 1133 is provided with a first protrusion 1135, and the first protrusion 1135 is located between the two side surfaces of the first slot 1133 along the X-axis direction.

[0072] The second core 210 is provided with a second slot 2124 and a second guide groove 2125. The second slot 2124 is disposed on the outer peripheral surface of the second intermediate portion 212 and is an elongated arc shape. The length direction of the second slot 2124 extends along the circumference of the second intermediate portion 212. The second guide groove 2125 is disposed on the outer peripheral surface of the second intermediate portion 212. One end of the second guide groove 2125 communicates with the second slot 2124, and the other end of the second guide groove 2125 passes through the end face of the second intermediate portion 212 away from the third mating portion 211. Preferably, the bottom surface of the second slot 2124 is provided with a second protrusion 2126 and a third protrusion 2127. The second protrusion 2126 and the third protrusion 2127 are both located between the two sides of the slot 2124 along the X-axis direction. Along the circumference of the second core 210, the second protrusion 2126 and the third protrusion 2127 are spaced apart. The second protrusion 2126 is close to the second guide groove 2125, and the third protrusion 2127 is far away from the second guide groove 2125. The height of the second protrusion 2126 is greater than the height of the third protrusion 2127.

[0073] The receiving cavity 251 of the locking fastener 250 passes through both ends of the locking fastener 250 along the X-axis. The cavity side of the receiving cavity 251 of the locking fastener 250 is provided with a first locking block 2512 that mates with the first locking slot 1133 and a second locking block 2513 that mates with the second locking slot 2124. Along the X-axis, the first locking block 2512 is located at one end of the receiving cavity 251, and the second locking block 2513 is located at the other end of the receiving cavity 251. In this embodiment, one end of the locking fastener 250 is sleeved on the second mating part 113 of the first adhesive core 110, and the first locking block 2512 of the locking fastener 250 slides into the first locking slot 1133 along the first guide groove 1134. The other end of the locking fastener 250 is sleeved on the fourth mating part 213 and the second intermediate part 212 of the second adhesive core 210, and the second locking block 2513 of the locking fastener 250 slides into the second locking slot 2124 along the second guide groove 2125.

[0074] Rotating the locking device 250 circumferentially causes the first locking block 2512 to slide to the side of the first protrusion 1135 away from the first guide groove 1134. The two sides of the first groove 1133 along the X-axis limit the first locking block 2512 in the X-axis direction. The first protrusion 1135 can prevent the first locking block 2512 from sliding in the opposite direction to the first guide groove 1134 and from sliding out of the first guide groove 1134, thus preventing the locking device 250 from falling off the first core 110.

[0075] At the same time, the second locking block 2513 slides between the second protrusion 2126 and the third protrusion 2127. The two sides of the second slot 2124 along the X-axis direction limit the second locking block 2513 in the X-axis direction, and the second protrusion 2126 and the third protrusion 2127 limit the second locking block 2513 in the circumferential direction, making the connection between the locking fastener 250 and the second glue core 210 more stable.

[0076] In this embodiment, since the height of the second protrusion 2126 is higher than the height of the third protrusion 2127, after the second locking block 2513 slides between the second protrusion 1132 and the third protrusion 2127, it is difficult for the second locking block 2513 to slide in the opposite direction past the second protrusion 2126, thus preventing the second locking block 2513 from sliding into the second guide groove 2125 and sliding out of the second guide groove 2125.

[0077] Please refer to Figure 18 and Figure 19The connector 1000 provided in the third embodiment of this application differs from the connector 1000 provided in the first embodiment in that the sealing method between the bottom surface of the insertion cavity 1131 and the fourth mating part 213 is different. Specifically, the sealing gasket 150 and the boss 1132 are omitted. The first connector 100 also includes a first sealing plug 170. The first sealing plug 170 has a first through hole 171, which penetrates the first sealing plug 170 along the X-axis direction. The first sealing plug 170 has a first isolation member 172, which is located inside the first through hole 171. The projection area of ​​the first isolation member 172 along the X-axis direction on the projection plane covers the projection area of ​​the first through hole 171 along the X-axis direction on the projection plane. The projection plane is perpendicular to the X-axis direction. In this embodiment, the projection plane can be the end face of the first sealing plug 170 along the X-axis direction. The first isolation member 172 has a first through hole 1721, which penetrates the first isolation member 172 along the X-axis direction and communicates with the first through hole 171.

[0078] A first sealing plug 170 is disposed in a first channel 1122. A first through hole 171 communicates with the first channel 1122, and the first sealing plug 170 partially exposes the side of the first rubber core 110 facing the second rubber core 210. Specifically, the first channel 1122 includes a first segment 1122a and a second segment 1122b that are interconnected. The diameter of the second segment 1122b is larger than the diameter of the first segment 1122a to form a first positioning step 1124. In other words, the sidewall of the first channel 1122 is provided with a first positioning step 1124. One end of the first sealing plug 170 along the X-axis direction sealably abuts against the first positioning step 1124, and the other end of the first sealing plug 170 along the X-axis direction exposes the side of the first rubber core 110 facing the second rubber core 210. The outer peripheral surface of the first sealing plug 170 sealably abuts against the inner peripheral surface of the second segment 1122b.

[0079] The second connector 200 further includes a second sealing plug 280, which has a second through hole 281 extending through the second sealing plug 280 along the X-axis. The second sealing plug 280 also includes a second isolating member 282 located within the second through hole 281. The projection area of ​​the second isolating member 282 along the X-axis on a projection surface covers the projection area of ​​the second through hole 281 along the X-axis on the projection surface. The projection surface is perpendicular to the X-axis. In this embodiment, the projection surface can be the end face of the second isolating member 282 along the X-axis. The second isolating member 282 has a second through hole 2821 extending through the second isolating member 282 along the X-axis and communicating with the second through hole 281.

[0080] The second sealing plug 280 is disposed in the second channel 2122, and the second through hole 281 communicates with the second channel 2122. The second sealing plug 280 partially exposes the side of the second core 210 facing the first core 110. Specifically, the second channel 2122 includes a third segment 2122a and a fourth segment 2122b that communicate with each other. The diameter of the fourth segment 2122b is larger than the diameter of the third segment 2122a, forming a second positioning step 2128. In other words, the sidewall of the second channel 2122 is provided with a second positioning step 2128. One end of the second sealing plug 280 along the X-axis direction sealably abuts against the second positioning step 2128, and the other end of the second sealing plug 280 along the X-axis direction exposes the side of the second core 210 facing the first core 110. The outer peripheral surface of the second sealing plug 280 sealably abuts against the inner peripheral surface of the fourth segment 2122b.

[0081] When the first connector 100 and the second connector 200 are plugged in, the first sealing plug 170 seals against the second sealing plug 280, and the first through hole 171 communicates with the second through hole 281, thereby making the first channel 1122 communicate with the second channel 2122.

[0082] In this embodiment, by providing a first sealing plug 170 in the first channel 1122 and a second sealing plug 280 in the second channel 2122, the first sealing plug 170 seals against the inner circumferential surface of the first channel 1122 and the second sealing plug 280 respectively, and the second sealing plug 280 seals against the inner circumferential surface of the second channel 2122. In this design, there are more sealing points and the sealing effect is better.

[0083] In this embodiment, the first through hole 171 is provided with a first isolation member 172 and the second through hole 281 is provided with a second isolation member 282. The first isolation member 172 and the second isolation member 282 can isolate foreign objects and prevent foreign objects from blocking the channel. In other embodiments, the first isolation member 172 and the second isolation member 282 can be omitted.

[0084] In this embodiment, the design of one end of the first sealing plug 170 sealingly abutting against the first positioning step 1124 not only limits the position of the first sealing plug 170, but also increases the contact area between the first sealing plug 170 and the first rubber core 110, resulting in a better sealing effect. Similarly, the design of one end of the second sealing plug 280 sealingly abutting against the second positioning step 2128 not only limits the position of the second sealing plug 280, but also increases the contact area between the second sealing plug 280 and the second rubber core 210, resulting in a better sealing effect.

[0085] In addition, the connector 1000 provided in the third embodiment of this application differs from the connector 1000 provided in the first embodiment in that the locking methods of the first core 110 and the second core 210 are different. Specifically, the side of the insertion cavity 1131 of the first core 110 is provided with a snap-fit ​​hole 1136, and the outer peripheral surface of the fourth mating part 213 of the second core 210 is provided with a relief groove 2132. The side of the relief groove 2132 along the Y-axis direction is provided with a snap-fit ​​member 2133. Along the Y-axis direction, the snap-fit ​​member 2133 and the bottom surface of the relief groove 2132 are spaced apart and opposite to each other. The Y-axis direction is perpendicular to the X-axis direction.

[0086] When the first connector 100 and the second connector 200 are inserted, the fourth mating part 213 of the second core 210 is inserted into the insertion cavity 1131 of the first core 110, and the snap-fit ​​member 2133 snaps into the snap-fit ​​hole 1136, thus locking the first core 110 and the second core 210 together. In this embodiment, the first core 110 and the second core 210 are locked together by snap-fit, which is simple in structure and easy to assemble. By partially placing the snap-fit ​​member 2133 in the clearance groove 2132, the size of the second core 210 can be reduced, which is beneficial for miniaturization design.

[0087] The embodiments of this application have been described in detail above. Specific examples have been used in this article to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
