The movable space 1012 is located on the right side of the connecting plate 301, and the movable space 1012 is connected to the first open port 102.

[0048] The sealing assembly 40 includes a first seal 401 and a second seal 402. The first seal 401 is arranged on the end wall of the connecting plate 301 near the active space 1012, and the first seal 401 is sealed with one of the first shell 10 and the second shell 20. The second seal 402 is arranged on the end wall of the connecting plate 301 near the sealed space 1011, and the second seal 402 is sealed with one of the first shell 10 and the second shell 20.

[0049] Specifically, the first seal 401 is arranged on the right end wall of the connecting plate 301, and the second seal 402 is arranged on the left end wall of the connecting plate 301. In some specific embodiments, when the installation space 101 is completely located in the first shell 10, the first seal 401 and the inner circumferential wall of the first shell 10 are sealed, and the second seal 402 and the inner circumferential wall of the first shell 10 are sealed.

[0054] The sealing assembly 40 is used to limit the flow of liquid from the active space 1012 to the sealed space 1011. Specifically, when the liquid enters the active space 1012 through the first open port 102, the first seal 401 and the second seal 402 jointly limit the flow of liquid from the active space 1012 to the sealed space 1011, thereby minimizing the flow of liquid into the communication device along the wire connected between the communication device and the connector 30, thereby minimizing the damage to the communication device by the liquid.

[0055] It should be noted that a connection circuit is provided within the connection plate 301. The wires located within the first housing 10 are electrically connected to the wires located within the second housing 20 via the connection circuit of the connection plate 301. Furthermore, by providing the connection circuit within the connection plate 301, contact between the connection circuit and liquid is minimized, thereby preventing liquid from interfering with the electrical connection between the wires located within the first housing 10 and the wires located within the second housing 20. Furthermore, the side of the connection plate 301 where the first sealing member 401 is provided can be provided with a waterproof coating and a hydrophobic coating, thereby minimizing direct contact between liquid and the connection plate 301.

By threading the first shell 10 and the fastener 60, the fastener 60 and the first shell 10 can be avoided as much as possible from being separated, and the dust cover 50 can be prevented from being separated from the first shell 10, thereby improving the connection reliability between the dust cover 50 and the first shell 10.

[0076] Reference Figure 5 and Figure 6 In some embodiments of the present application, a clamping portion 303 is provided on the side wall of the connecting plate 301, and the clamping portion 303 extends through the installation space 101 into one of the first shell 10 and the second shell 20, and the clamping portion 303 is connected and cooperated with the corresponding shell. Specifically, along the first direction of the waterproof connector 100, the clamping portion 303 can be provided on the left end wall of the connecting plate 301 or the right end wall of the connecting plate 301, the clamping portion 303 provided on the right end wall of the connecting plate 301 extends through the installation space 101 into the first shell 10 and is connected and cooperated with the first shell 10, and the clamping portion 303 provided on the left end wall of the connecting plate 301 extends through the installation space 101 into the second shell 20 and is connected and cooperated with the second shell 20, so that the clamping portion 303 can be prevented from shaking in the first shell 10 or the second shell 20 as much as possible, and thus the interference of the clamping portion 303 with the wire can be avoided, resulting in the wire being unable to be inserted into the corresponding shell.

[0077] In addition, the clamping portion 303 is suitable for elastic deformation to clamp the wire. Specifically, when the wire is electrically connected to the connecting portion 302, the clamping portion 303 clamps the wire and inserts it into the end portion of the corresponding shell, thereby minimizing the wire from deviating from the preset position and preventing the wire from being unable to be electrically connected to the connecting portion 302, thereby improving the working reliability of the waterproof connector 100.

[0078] Moreover, in the process of the wire passing through the first opening 102 or the second opening and being inserted into the corresponding shell, the end of the wire inserted into the shell abuts against the end wall of the clamping portion 303 away from the inner wall of the first shell 10, and the wire drives the clamping portion 303 to elastically deform, and the end wall of the clamping portion 303 abutting against the wire moves close to the inner wall of the first shell 10, so that the clamping portion 303 can clamp wires of different sizes, thereby improving the user experience of the waterproof connector 100.

[0079] In some specific embodiments, referring to Figure 5 and Figure 7, the left side wall of the connecting plate 301 and the right side wall of the connecting plate 301 are each provided with two clamping portions 303 that are opposite and spaced apart. Along the second direction of the waterproof connector 100, one of the two clamping portions 303 is provided at the front end portion of the connecting plate 301, and the other of the two clamping portions 303 is provided at the rear end portion of the connecting plate 301. The wire is inserted between the two clamping portions 303, and the two clamping portions 303 clamp the wire together. The second direction of the waterproof connector 100 can refer to Figure 5 The front-to-back direction.

[0080] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
