During the insertion process, the guiding portion 2113 on the third sealing portion 211 of the second connector 20 is aligned with the first infusion liquid 11 by the guiding groove 1113 formed with the self-guide structure. At this time, the first connector 10 and the second connector 20 are both in a self-sealing state; during the continuous insertion process, the first housing 13 and the second housing 23 are in contact with each other, and the first and second housings 11 and 23 are A portion of the second infusion liquid 21 is located in the first housing 13 and the liquid in the first housing 13 flows into the second connector 20 through the third liquid guiding groove 2132. In order to achieve the transfer of the liquid, the first housing 13 and the second housing 23 are pressed against each other to achieve the sealing of the first connector 10 and the second connector 20. When the first connector 10 and the second connector 20 are in the engaged state, the liquid (for example, oil) in the first pipe 201 enters the channel 2130 in the second liquid 21 through the channel 1130 in the first liquid 11 , reaching the second pipe 202.
连接机构100的分离过程与插合过程相反，持续分离过程时，第一复位件15和第二复位件25复位而使连接机构100恢复如图1所示状态。在本实施例中，第一连接头10和第二连接头20通过一外部自锁结构实现定位，因所述外部自锁结构不是本案的重点，因此不做详细描述。The separation process of the connection mechanism 100 is opposite to the insertion process. When the separation process is continued, the first reset member 15 and the second reset member 25 are reset to restore the connection mechanism 100 to the state shown in FIG. In this embodiment, the first connector 10 and the second connector 20 are positioned by an external self-locking structure, and the external self-locking structure is not the focus of the present invention, and thus will not be described in detail.
