A fourth socket 401 is provided on the first waterproof gasket 4 and corresponds in position to and is communicated with the first socket 101-1.

[0025] The integrated terminal 3 comprises, from front to back, a plug-in portion 301, a mounting portion 302 and a crimping portion 303. The plug-in portion 301 is a columnar structure, and the mounting portion 302 comprises a first limiting cylinder 302-1 and a second limiting cylinder 302-2. Both the first limiting cylinder 302-1 and the second limiting cylinder 302-2 are columnar structures. The first limiting cylinder 302-1 is on the front side of the second limiting cylinder 302-2 and is connected to the mounting portion 302. The diameter D2 of the first limiting cylinder 302-1 is greater than the diameter D1 of the mounting portion 302. A circular arc transition surface is provided at the connection position between the mounting portion 302 and the first limiting cylinder 302-1. The diameter D3 of the second limiting cylinder 302-2 is smaller than the diameter D2 of the first limiting cylinder 302-1.
