Description of the embodiments

Fig. 1, fig. 2 and fig. 3 show a schematic perspective view, a schematic exploded perspective view and a schematic sectional structure of a waterproof ring according to the present utility model. Referring to fig. 4 and 5, a schematic structural diagram of a dispensing range of the waterproof glue and a schematic structural diagram of UV glue according to the present utility model are shown.

The utility model relates to a socket electric connector, which is a USB3.0 or USB3.1 connector, wherein the socket electric connector 1 mainly comprises an insulating main body 10, socket terminals 11, an iron shell 12, a colloid shell 13, UV glue 14, a waterproof ring 15, a rear plug 16 and waterproof glue 17, wherein the insulating main body 10 comprises a base 100 and a tongue piece 102, the base 100 forms a circle of grooves 1000 on the peripheral wall surface and a mounting groove 1002 on the bottom surface, each socket terminal 11 is arranged on the base 100 and the tongue piece 102, the rear plug 16 is arranged in the mounting groove 1002 and penetrates through each socket terminal 11, and a gap 104 is formed between the rear plug 16 and each socket terminal 11. The iron shell 12 defines a mounting space 120 for disposing the insulating main body 10, the glue shell 13 defines a housing space 130, an opening 132 at the front end of the housing space 130 and a mounting opening 134 at the rear end, wherein the housing space 130 is disposed for disposing the iron shell 12, the iron shell 12 is disposed in a manner of being inserted into the opening 132 from the mounting opening 134, the iron shell 12 is disposed adjacent to the opening 132 to expose a glue surface 126, the glue shell 13 and the iron shell 12 define an assembly gap 136, the uv glue 14 is disposed on the glue surface 126 in a manner of spot gluing and seals the assembly gap 136, in addition, the waterproof ring 15 is made of rubber material, is sleeved on the groove 1000 through the elastic effect of itself and abuts against the inner surface of the iron shell 12, and the waterproof glue 17 is disposed at the position of the rear plug 16 in a manner of spot gluing and shields the position of the gap 104 to prevent water vapor from entering from the gap 104 between the rear plug 16 and the socket terminal 11.
