The connecting tube 11 has multiple limiting holes 111, and the washer 4 has multiple fixing blocks 41, each fixing block 41 located in a specific limiting hole 111.

[0020] Referring to Figure 3, in this embodiment, the plug conductive module 2 includes a first terminal block 20 disposed on the assembly part 13 and a plurality of conductive parts 23 disposed on the first terminal block 20. The first terminal block 20 is a circuit board 20A, but is not limited thereto. In some embodiments, the first terminal block 20 is an insulator, and using a circuit board 20A saves on the cost of manufacturing molds. The circuit board 20A has a long axis 20A1 extending along the first axis X direction and a short axis 20A2 extending along the third axis Z direction. The assembly part 13 has two sliding grooves 132 located on both sides of the groove 131, and two sliders 202 protrude outward along the third axis Z direction on both sides of the first terminal block 20, with each slider 202 correspondingly positioned in the respective sliding groove 132.

[0021] Referring to Figure 3, the multiple conductive parts 23 can be divided into two groups. One group is used to provide power output (positive and negative terminals), and the other group is used to transmit detection signals (positive and negative terminals), such as connecting the sensor 402 (as shown in Figure 1) to provide liquid level sensing function. The contact point 231 of each conductive part 23 is a circular conductive sheet, and the conductive parts 23 are arranged side by side and spaced apart. Each conductive part 23 has a contact point 231 and a wiring segment 232 arranged side by side on the surface of the first terminal block 20.

The vent pipe 31 includes a flexible tube 311 and an outer sheath 312, providing a channel for transporting air. The wires 32 include a first wire, a second wire, a third wire, and a fourth wire. Each wire is evenly distributed around the outer perimeter of the flexible tube 311 and extends coaxially. After the vent pipe 31 is formed, each wire 32 is covered by the outer sheath 312 and integrated with the vent pipe 31. The ends 322 of each wire 32 are exposed outside the outer sheath 312. The wires 32 are arranged side by side along the third axis Z direction, and the ends 322 of each wire 32 are respectively connected to the wiring segments 232 of each conductive part 23. The first and second wires can be connected to the heating element 401 via the plug conductive module 2 and the connecting wire (as shown in Figure 1). The third and fourth wires can be connected to the sensor 402 via the plug conductive module 2 to achieve the heating and sensing functions required by the electric control cover and the milker. The cover 33 covers the joint between the wiring segment 232 and the wire 32 to prevent moisture or loosening.

[0024] During assembly of the plug connector 200, the flexible tube 311 of the vent tube 31 is inserted into the insertion tube of the connector tube 12.

The wires 32 are coaxially arranged, ensuring even stress distribution, and are protected by the tail sleeve 5, enhancing durability. Finally, the washer 4 is fitted over the front end of the connector tube 11 to provide an airtight seal. The tail sleeve 5 covers the sheath 33, providing internal and external protection and stress cushioning, completing the assembly of the plug connector 200.

[0025] Please refer to Figure 6, which is an exploded view of the standard socket connector 300. In this embodiment, the socket connector 300 includes an insulating body 6 and a socket conductive module 7. The insulating body 6 is generally rectangular, and a socket 61 is provided in the center of the insulating body 6 (as shown in Figure 8). An inner tube 64 is provided inside the socket 61 (as shown in Figure 8). An air duct 62 communicating with the inner tube 64 is provided outside the insulating body 6. When the plug connector 200 is inserted into the socket connector 300, the inner tube 64 corresponds to the air duct 31 of the plug connector 200. The air duct 62 is located in the center of the socket 61, so that it is coaxially engaged with the air duct 31 of the plug connector 200. In addition, the gasket 4 of the plug connector 200 is sleeved on the inner tube 64 to improve the sealing performance. In addition, the insulating body 6 includes a mounting part 60 and a mating part 63 corresponding to the assembly part 13 located on the connector 1 (as shown in Figure 7). The mating part 63 is a plane corresponding to the plane of the assembly part 13. When the plug connector 200 is inserted into the socket connector 300, the mating part 63 and the assembly part 13 prevent mis-insertion. In addition, the mounting part 60 is a rectangular groove, and the mounting part 60 has a plurality of terminal slots 601 that communicate with the socket 61. The inner wall of the mounting part 60 has a plurality of locking blocks 603.

[0026] The socket conductive module 7 includes a second terminal block 70 disposed on the mounting portion 60 and a plurality of probe terminals 73 disposed on the second terminal block 70. The second terminal block 70 is a rectangular block with a plurality of through holes 701, and each probe terminal 73 is disposed in a respective through hole 701. The outer wall surface of the second terminal block 70 has a plurality of fastening blocks 703, and each locking block 603 can be correspondingly fastened to each fastening block 703. Each probe terminal 73 has a contact 731 and an external member 732 at both ends. Each contact 731 extends from each terminal slot 601 and is disposed in the socket 61. Each contact 731 is adapted to mate with each contact point 231 of each conductive part 23. Each external member 732 extends to the outside of the insulating body 6 for circuit connection. In this embodiment, the probe terminal 73 includes a tube 733, an elastic element 734 (compression spring or spring sheet) located inside the tube 733, a contact 731, and an external member 732. The contact 731 and the external member 732 respectively abut against the two ends of the elastic element 734, and the contact 731 and the external member 732 can move elastically under the abutment of the elastic element 734.

[0027] In this embodiment, the probe terminal 73 (Pogo Pin) is a spring-loaded pin or spring connector, an electronic component comprising a pin shaft, spring, and pin tube, used to achieve a stable electrical connection. Multiple probe terminals 73 can be divided into two groups, one group for providing power output (positive and negative terminals), and the other group for transmitting detection signals (positive and negative terminals), for example, for connecting sensor 402 (as shown in Figure 1). Each probe terminal 73 can be arbitrarily combined to provide power output and transmit detection signals.

[0028] When the socket connector 300 is assembled, the socket conductive module 7 is assembled on the mounting part 60, so that each contact 731 passes through each terminal slot 601 to the socket 61, so that the corresponding positions of the contact points 231 of the plug conductive module 2 can make contact.

[0029] Please refer to Figures 8 and 9. Figure 8 is a side cross-sectional view of the plug connector 200 (marked positions VIII-VIII in Figure 2) inserted into the standard socket connector 300. Figure 9 is a side cross-sectional view of the plug connector 200 inserted into the waterproof socket connector 300 from the same perspective as Figure 8. When the plug connector 200 is inserted into the socket connector 300, the vent pipe 31 connects to the air guide pipe 62, forming a gas channel. Simultaneously, the contact points 231 of each conductive part 23 mate with the contact pieces 731 of each probe terminal 73, achieving electrical conductivity. During milking, the central vent pipe 31 and the peripheral plug conductive module 2 work simultaneously to achieve stable heating, milk extraction, and synchronized electrical control. Furthermore, the sensor 402 provides liquid level sensing functionality, enhancing user comfort and safety.

[0030] In summary, according to some embodiments, the wiring assembly of the plug connector of the conductive connection device is provided with multiple wires and vent tubes, and its structure can combine the gas delivery function of a hollow conduit with the conductive function.
