[0037] As Figures 1 to 4 shown, the connector 100 in the embodiments of the present application includes:
[0038] a first plug 11, which has a first connection terminal 111;
[0039] a second plug 12, which has a second connection terminal 121;
[0040] A circuit board 13, on which a first connection portion 131 connected to the first connection terminal 111 and a second connection portion 132 connected to the second connection terminal 121 are provided; and
[0041] A seal 14 that protects the connection positions between the first connection terminal 111 and the first connection portion 131 and between the second connection terminal 121 and the second connection portion 132.
[0042] In the above embodiment, the first plug is, for example, a board plug, which can be used to connect to a functional circuit board inside a product (such as a sensor) configured with this connector; the second plug is, for example, an external plug, which is used to output a working signal.

[0044] The names of the above plugs are only for illustration. Depending on the different products configured with this connector, the first plug and the second plug may also have other names, and this application does not limit this.
[0045] In some embodiments, as Figures 1 to 4 shown, the first plug 11 further has a first housing 112 surrounding the first connection terminal 111, the second plug 12 further has a second housing 122 surrounding the second connection terminal 121, both ends of the seal 14 are hermetically fixed to the first housing 112 and the second housing 122 respectively, and the circuit board 13 is located inside the seal 14.
[0046] According to the above embodiment, by connecting the housings of the two plugs through the seal 14 and sealing the circuit board, on the one hand, it can protect the connection (such as welding or plugging) between the external plug and the circuit board, and on the other hand, it can also protect the connection (such as welding or plugging) between the board plug and the circuit board, improving the sealing performance of the connector and being simple to implement.
[0047] In the above embodiment, the shapes of the first housing 112 and the second housing 122 are not limited, Figures 2 to 4 and in the example, the first housing 112 is in the shape of a cuboid and the second housing 122 is in a substantially cylindrical shape. In specific implementation, depending on the different structures and positions of the connection terminals, the first housing 112 and the second housing 122 may also be other shapes.
[0048] In the above embodiments, the seal 14 can be a transparent soft rubber seal. Thus, it is convenient for light to pass through, facilitating the operator to observe the connection inside the seal 14, and improving the safety of the connector. This application is not limited thereto. The seal 14 can also be made of other materials, as long as it can connect the outer shells of the two plugs and seal the circuit board.
[0049] In the above embodiments, there is no limitation on the sealing method between the seal 14 and the two outer shells. For example, it can be achieved by applying a sealant, or by secondary molding, etc. In addition, in the above embodiments, the seal 14 and the two outer shells can be integrally formed or separately formed. The specific forming method is not limited in this application.
[0050] In some embodiments, as Figures 2 to 4 shown, the first connection terminal 111 is inserted into the first connection part 131. This application is not limited thereto. For example, the first connection terminal 111 can also be welded to the first connection part 131, or the first connection terminal 111 can be connected to the first connection part 131 by other means. Thus, the connection stability and safety are improved.
[0051] In some embodiments, as Figures 2 to 4 shown, the second connection terminal 121 is welded to the second connection part 132. This application is not limited thereto. The second connection terminal 121 can also be inserted into the second connection part 132, or the second connection terminal 121 can be connected to the second connection part 132 by other means. Thus, the connection stability and safety are improved.
[0052] In the above embodiments, there is no limitation on the implementation method of the insertion. For example, it can be a TYPE-C type insertion, or other types of insertions, etc.
[0053] In some embodiments, as Figure 2 and Figure 3 shown, the number of the first connection terminals 111 is at least one, Figure 2 and Figure 3 shows four first connection terminals 111. The number of the second connection terminals 121 is also at least one, Figure 2 and Figure 3 shows four second connection terminals 121. Thus, the connection of signals and current is achieved.
[0054] In the above embodiments, by setting multiple connection terminals, the connection stability is further improved, thus ensuring the performance of the connector.
[0055] In some embodiments, the second connection terminals 121 are located on the upper and lower surfaces of the circuit board 13.

For example, they are soldered to the first connection portions 131 on the upper and lower surfaces of the circuit board 13. The second connection terminals 121 may also be located on the upper surface of the circuit board 13. For example, they are inserted into the second connection portions 132 on the upper surface of the circuit board 13, and so on.
