The glue hole, the first annular groove and the annular filling groove are all filled with waterproof glue, and a sealing ring is embedded in the second annular groove, and the sealing ring protrudes from the outer wall of the shielding shell.

As a preferred solution, two annular protrusions protrude from the outer surface of the base of the insulating body, the two annular protrusions are located on both sides of the annular filling groove, and the two annular protrusions are closely matched with the inner wall of the shielding shell.

As a preferred solution, the sealing ring is integrally formed and connected with the waterproof glue.

As a preferred solution, the outer surface of the sealing ring has two annular protrusions arranged one behind the other.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

The glue injection hole, the first annular groove and the annular filling groove are all filled with waterproof glue, and a sealing ring is embedded in the second annular groove, so that between the shielding shell and the outside, between the insulating body and the shielding shell A good seal is formed between the shielding sheet, each terminal and the insulating body to achieve a better waterproof effect and meet the requirements of use.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Please refer to Fig. 1, which shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a lower row of terminals 20, an upper row of terminals 30, a shielding sheet 40, a shielding sleeve 50 and a shielding shell 60 .

The lower row of terminals 20, the upper row of terminals 30 and the shielding sheet 40 are all arranged on the insulating body 10, the shielding sheet 40 is located between the lower row of terminals 20 and the upper row of terminals 30; the shielding sleeve 50 is sleeved on the tongue of the insulating body 10 Between the rear end of the board 11 and the front end of the base 12 , the shielding sleeve 50 is in contact with the shielding sheet 40 ;

The side of the base 12 of the insulating body 10 is recessed with an annular filling groove 101. The aforementioned lower row of terminals 20, upper row of terminals 30 and shielding sheet 40 all pass through the annular filling groove 101, and the inner wall of the rear end of the shielding shell 60 corresponds to the annular filling groove 101. The filling groove 101 is concavely provided with a first annular groove 61 , the outer wall of the rear end of the shielding shell 60 is concavely provided with a second annular groove 62 , and the bottom surface of the second annular groove 62 is provided with a glue injection hole that communicates with the first annular groove 61 .
