[0046] The metal shell 5 covers the first terminal assembly 2, the second terminal assembly 3 and at least one metal shielding plate 4, and the two opposite sides of at least one metal shielding plate 4 are connected to the metal shell 5. Please refer to Figure 3 The metal shell 5 of this embodiment has multiple grounding plug terminals 5a and multiple grounding connection terminals 5b.

[0047] Specifically, if Figures 3 to 7 As shown, the first terminal assembly 2 has a first insulating body 22 and two first signal terminals 21, the two first signal terminals 21 are embedded in the first insulating body 22, and the first insulating body 22 and the two first signal terminals 21 are injection molded integral parts. The first insulating body 22 has a first through groove 23, and the first through groove 23 is located between the two first signal terminals 21.

[0048] The second terminal assembly 3 has a second insulating body 32 and two second signal terminals 31. The two second signal terminals 31 are embedded in the second insulating body 32. The second insulating body 32 and the two second signal terminals 31 are injection molded integral parts. The second insulating body 32 has a second through-slot 33. The second through-slot 33 is located between the two second signal terminals 31 and is aligned with the first through-slot 23.

[0049] The number of the metal shielding plate 4 is one, and the metal shielding plate 4 is fixedly received in the first through slot 23 and the second through slot 33. The metal shell 5 covers the first terminal assembly 2, the second terminal assembly 3 and the metal shielding plate 4, and the two opposite sides of the metal shielding plate 4 are connected to the metal shell 5. Since the first terminal assembly 2 and the second terminal assembly 3 are injection molded parts, during assembly, it is only necessary to assemble the first terminal assembly 2, the metal shielding plate 4 and the second terminal assembly 3 according to the assembly sequence, and then install them into the metal shell 5, and finally fix the metal shielding plate 4 and the metal shell 5 together by welding, which can reduce the assembly steps, improve the assembly efficiency, and facilitate the realization of automated production. The welding is preferably laser spot welding.

[0050] In a preferred embodiment, Figure 8 Schematic diagram of the structure of the metal shielding plate of the first embodiment of the present application. Figure 8 As shown, the metal shielding plate 4 has a plurality of third positioning columns 41 on opposite sides, and the plurality of third positioning columns 41 are exposed from at least one first through slot 23 and at least one second through slot 33. The metal shell 5 is also provided with a plurality of third positioning holes 51 (such as Figure 1 As shown), the third positioning column 41 is disposed in the corresponding third positioning hole 51, and the plurality of third positioning columns 41 are inserted into the corresponding third positioning holes 51 when the metal shielding plate 4 is installed to position the metal shielding plate 4, but the present invention is not limited thereto.

[0051] Specifically, the metal shielding plate 4 has two third positioning columns 41 on two opposite sides respectively, and the number of third positioning holes 51 is four. It can be seen that the four third positioning holes 51 are respectively arranged on both sides of the metal shell 5, and the two third positioning columns 41 on one side of the metal shielding plate 4 are correspondingly inserted into the two third positioning holes 51 located on one side of the metal shell 5.

[0052] It should be understood that the above only uses two third positioning columns 41 as an example to illustrate the multiple third positioning columns 41, but the present application is not limited to this. The multiple third positioning columns 41 can also be other numbers. For example, the multiple third positioning columns 41 can be three, four, five or more than six.

[0053] In a preferred embodiment, the inner surface of the metal shell 5 has a plurality of welding protrusions 52 , which correspond to the metal shielding plate 4 located in the first through-slot 23 and the second through-slot 33 , and are used to perform laser spot welding connection between the metal shielding plate 4 and the metal shell 5 .

[0054] Specifically, the inner surface of the metal shell 5 has a plurality of welding bumps 52 .

Ten welding bumps 52 are located on the inner surface of the first shell 501 of the metal shell 5, and another ten welding bumps 52 are located on the inner surface of the second shell 502 of the metal shell 5. The ten welding bumps 52 located on the first shell 501 and the ten welding bumps 52 located on the second shell 502 are respectively arranged along the path of the metal shielding plate 4.

[0055] After the terminal structure 1 is completed, that is, the metal shell 5 covers the first terminal assembly 2, the second terminal assembly 3 and the metal shielding plate 4, each metal shielding plate 4 is connected to the first shell 501 on the side protruding from the first insulating body 22, and each metal shielding plate 4 is connected to the second shell 502 on the side protruding from the second insulating body 32. The metal shielding plate 4 is laser spot welded to the first shell 501 and the second shell 502 through twenty welding bumps 52 to fix the metal shielding plate 4 to the metal shell 5 together.

[0056] Since it is difficult to realize the rigid mechanical structure of the shielding metal and the metal shell 5 in the prior art, the shielding metal is usually formed by a conductive plastic insert, and the connection with the metal shell 5 is mainly made by hot-melt contact of the plastic column. The terminal structure 1 of this embodiment uses a plurality of welding bumps 52 to perform laser spot welding on the metal shielding plate 4 and the metal shell 5, so as to realize the rigid mechanical connection between the metal shielding plate 4 and the metal shell 5 and improve the assembly speed.

[0062] Specifically, if Figures 9 to 13 As shown, it can be seen that the buckle 5041 is a raised structure protruding inward from the surface of the second flange 504, the abutting surface 5042 is the outer surface of the raised structure, the inserted portion 54 is a vertical through groove, the positioning portion 55 is a horizontal through groove, and the inserted portion 54 and the positioning portion 55 form a T-shaped groove structure.

The two first positioning columns 222 are inserted into the corresponding first positioning holes 322 to position and connect the first insulating body 22 and the second insulating body 32 together.

[0069] It should be understood that the above only takes two first positioning columns 222 and two first positioning holes 322 as an example to illustrate multiple first positioning columns 222 and multiple first positioning holes 322, but the present application is not limited to this. The number of first positioning columns 222 matches the number of first positioning holes 322, and the first positioning columns 222 and the first positioning holes 322 can also be other numbers. For example, the first positioning columns 222 and the first positioning holes 322 can be three, four, five or more than six respectively.

[0070] In a preferred embodiment, please refer again to Figure 4 and Figure 7 A plurality of second positioning posts 223 are respectively disposed on the surface of the first insulating body 22 away from the second insulating body 32 and the surface of the second insulating body 32 away from the first insulating body 22. A plurality of second positioning holes 53 are also disposed on the first shell 501 and the second shell 502, and each second positioning post 223 is inserted into a corresponding second positioning hole 53.
