(4) The first terminal group 20 and the intermediate shielding sheet 5 are integrally formed in the insulating body 1, and the second terminal group 21 is assembled and fixed on the insulating body 1. Compared with two rows of terminals The groups are fixed on the tongue plate 11 by assembly, without thinning or digging out the tongue plate to ensure the strength of the tongue plate 11; compared with the two rows of terminals, which are fixed on the tongue plate 11 by one-piece molding, to ensure that the terminals The tongue plate 11 is stably held without damage, and the production cost is reduced at the same time.

(5) The shielding shell 6 has a first lead-in portion 65 , the first lead-in portion 65 is connected to a first metal wire clamp 40 , and the shielding shell 6 is electrically connected to the first metal wire clamp 40 . Sexual connection conducts the signal interference between the first row of cables 30 to the shielding shell 6 through the first metal clamp 40 and leads to the outside, and the shielding shell is connected to the upper and lower shielding sheets 70, 71; the intermediate shielding sheet 5 has a second conducting portion 51, and the second conducting portion 51 is connected to the second metal clamp 41, so that the intermediate shielding sheet 5 and the second The metal clamp 41 is electrically connected to form a ground and provide the best shielding effect, and the intermediate shielding sheet 5 is connected to the upper and lower shielding sheets 70, 71, so that the intermediate shielding sheet 5 is connected to the shielding shell 6, Connect the first metal wire clamp 40, the second metal wire clamp 41 and the intermediate shielding sheet 5 with the shielding shell 6 to form a loop, and connect the first row of cables 30 and the second row of cables 31 Signal interference is led to the outside through the shielding shell 6 .

The above detailed description is only a description of the preferred embodiment of the utility model, and does not limit the patent scope of the utility model. Therefore, all equivalent technical changes made by using the instructions and illustrations of this creation are included in this creation. within the scope of the patent.
