DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0018] In the description of this application, it should be understood that the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", and "third" may explicitly or implicitly include one or more features.

[0019] The automotive through-cylinder connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. It is mainly used in components such as automobile engines or automatic transmissions. The metal contacts installed inside the insulator shell cooperate with each other to achieve its connection and conduction function, and play the role of transmitting current and signals. The current through-cylinder connector generally includes a male end, a female end and a cylinder body. The male end and the female end are sealed by a sealing ring, and the male end and the cylinder body are also sealed by a sealing ring. The use of two sealing rings makes the structure of the through-cylinder connector complicated and not simple enough; at the same time, the sealing ring monomer is expensive and requires multiple installation processes, which is time-consuming and labor-intensive.

[0020] In view of this, an embodiment of the present application provides a connector to overcome at least one of the above-mentioned technical problems.

[0021] See also Figure 1 In the embodiment of the present application, the connector includes a first connector 10, a second connector 20 and a third connector 30. The second connector 20 is connected to the first connector 10, and the second connector 20 includes a sealing portion 21, which is sealed and connected to the first connector 10; the third connector 30 is arranged around the second connector 20 and is sealed and connected to the sealing portion 21. Among them, the first connector 10 can be the female end of the connector, the second connector 20 can be the male end of the connector, and the third connector 30 can be the cylinder of the connector. Specifically, by arranging the sealing portion 21 on the second connector 20, the second connector 20 can be sealed and connected to the first connector 10, and the second connector 20 can be sealed and connected to the third connector 30, without using two sealing structures for sealing respectively, thereby reducing the number of sealing structures used and simplifying the structure. Since only one sealing structure is needed, the cost of the sealing structure is reduced, the installation process is reduced, time is saved, and the labor intensity is reduced; at the same time, reducing the number of sealing structures used can also effectively avoid the failure risk caused by multiple parts, such as the sealing structure falling off or turning over.

[0022] See also Figure 1 and Figure 5In some embodiments, the first connector 10 includes a docking portion 11 and a shell 12. The docking portion 11 is connected to the second connector 20; the shell 12 is connected to the docking portion 11 and is arranged around the docking portion 11; wherein, an accommodating cavity 13 surrounding the docking portion 11 is formed between the shell 12 and the docking portion 11, and the second connector 20 is at least partially located in the accommodating cavity 13. Specifically, one end of the docking portion 11 is embedded in the interior of the second connector 20, and the shell 12 is connected to the docking portion 11 in an circumferential manner and is integrally formed with the docking portion 11, so that an accommodating cavity 13 surrounding the docking portion 11 is formed between the shell 12 and the docking portion 11. After the docking portion 11 is embedded in the interior of the second connector 20, a portion of the second connector 20 is also embedded in the interior of the accommodating cavity 13.

[0023] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the second connector 20 further includes a body 22, and the body 22 is at least partially located in the accommodating cavity 13. The third connector 30 is at least partially located in the accommodating cavity 13, and is connected to the outer shell 12, and is used to limit the body 22. Specifically, after a portion of the docking portion 11 is embedded in the interior of the body 22, a portion of the body 22 is also embedded in the accommodating cavity 13. Among them, the third connector 30 is also at least partially embedded in the accommodating cavity 13, and the third connector 30 surrounds and is sleeved on the second connector 20; at the same time, the third connector 30 has a plurality of first card blocks, and the outer shell 12 has a second card block corresponding to the number and position of the first card blocks. Through the cooperation of the first card block and the second card block, the third connector 30 can be prevented from moving inside the accommodating cavity 13, which also plays a certain limiting role on the body 22.

[0024] See also Figure 1 and Figure 2 In some embodiments, the body 22 is sleeved on the docking portion 11 and is sealed and connected to the docking portion 11 through the sealing portion 21; the third connecting member 30 is arranged around the body 22 and is sealed and connected to the body 22 through the sealing portion 21.

The first sealing segment 211 is arranged around the docking portion 11 and is used to seal the docking portion 11 and the body 22. Specifically, after one end of the docking portion 11 is embedded in the docking cavity 222 in the body 22, the first sealing segment 211 on the sealing portion 21 is located in the docking cavity 222, which can be used to seal the docking portion 11 and the body 22 inside the docking cavity 222, thereby improving the sealing of the connection between the two.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the first sealing section 211 has a first convex ring, which is disposed around the docking portion 11 and is sealed and connected to the docking portion 11. Specifically, the first sealing section 211 has at least one first convex ring, which is disposed around the docking portion 11, and can fit more closely with the docking portion 11, further improving the sealing performance of the connection between the docking portion 11 and the body 22.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the sealing portion 21 further includes a second sealing segment 212, and the second sealing segment 212 is located outside the body 22. The second sealing segment 212 is arranged around the body 22, and is used to seal and connect the third connecting member 30 and the body 22. Specifically, the second sealing segment 212 located outside the body 22 is arranged around the body 22, and is located between the third connecting member 30 and the body 22, and at the same time, it is tightly attached to the third connecting member 30 and the body 22, thereby improving the sealing of the connection between the third connecting member 30 and the body 22.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the second sealing segment 212 has a second convex ring, which is disposed around the body 22 and is sealed and connected to the body 22. Specifically, there is at least one second convex ring, which surrounds the outside of the body 22. When the third connecting member 30 is disposed around the body 22, the second convex ring fits more closely with the surface of the third connecting member 30, thereby further improving the sealing performance of the connection between the third connecting member 30 and the body 22.

[0029] See also Figure 2 , Figure 3 and Figure 4In some embodiments, the body 22 has a connection hole 221, and the connection hole 221 is connected to the docking cavity 222. The sealing portion 21 also includes a connection segment 213, which is arranged in the connection hole 221 and is used to connect the first sealing segment 211 and the second sealing segment 212. Specifically, the connection hole 221 is used for the connection segment 213 to pass through, so that the connection segment 213 can be connected to the first sealing segment 211 inside the docking cavity 222, and can also be connected to the second sealing segment 212 outside the body 22.

[0030] See also Figure 3 and Figure 4 In some embodiments, there are multiple connection holes 221 and multiple connection segments 213, and the multiple connection holes 221 correspond to the multiple connection segments 213. Specifically, the number of connection holes 221 and the number of connection segments 213 can be multiple, and the number and position of the two correspond to each other. The connection holes 221 are provided for the connection segments 213 to pass through, and a part of the sealing part 21 can be installed inside the body 22, and a part of the sealing part 21 can be installed outside the body 22.

[0031] See also Figure 3 In some embodiments, the sealing part 21 is an integrated structure and can be integrally formed by a mold without adding additional processes, thereby reducing the cost of the sealing structure and simplifying the structure of the connector. The integrally formed sealing part 21 is already in the assembly position when shipped, without the risk of falling off, thereby ensuring the stability of the sealing part 21 during use; at the same time, the integrally formed sealing part 21 only needs to be processed using a set of sealing molds, thereby avoiding a complex sealing structure.
