Detailed Description

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, the structure of the base, the rear plug and the waterproof ring of the present utility model and the structure of the UV glue 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, 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 is provided with 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 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, a plugging port 122 and a mounting port 124, the plugging port 122 and the mounting port 124 are communicated with the mounting space 120, the insulating main body 10 is inserted and mounted by the mounting port 124, the iron shell 12 is bent outwards at the end of the plugging port 122 to form a first limit structure 1220 and a second limit structure 1222 adjacent to the periphery of the plugging port 122, wherein the second limit structure 1222 is a horizontal convex hull horizontally arranged with the plugging port 122. Wherein the first limit structure 1220 and the second limit structure 1222 define an installation space 1224 therebetween.

In addition, the UV glue 14 is mainly a liquid glue, and is mainly disposed in the mounting space 1224 in a dispensing photo-curing manner, and the UV glue 14 is higher than the first limit structure 1220 and the second limit structure 1222, so that gaps between the iron shell 12 and the mounted product can be shielded by the UV glue 14, and moisture is prevented from entering the product.

Furthermore, the waterproof ring 15 is made of rubber, the waterproof ring 15 is sleeved on the groove 1000 and contacts the inner surface of the iron shell 12 through the elastic effect of the waterproof ring, and the waterproof glue 17 is dispensed at the position of the gap 104 in a dispensing mode, so that the waterproof effect can be achieved through the structure.
