Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

The utility model provides a structure 100 of female seat EMI signal of shielding TYPE-C realizes the full shielding effect to the EMI signal through full laminated structure. Fig. 1-2 are different view diagrams of the structure 100 for shielding TYPE-C female seat EMI signals according to the embodiment of the present invention, and the following describes the specific structure in detail with reference to fig. 1, fig. 2 and fig. 3:

referring to fig. 1-3, the structure 100 for shielding the TYPE-C female receptacle EMI signal of the present embodiment includes a PCB 10, a TYPE-C female receptacle 20, and a shielding cover 30, wherein the PCB 10, the TYPE-C female receptacle 20, and the shielding cover 30 are sequentially disposed from bottom to top.

The shielding can 30 of the present embodiment is soldered on the PCB 10 to form a cavity (not shown). Preferably, the lower end of the shielding cover 30 is attached to the upper surface of the PCB board 10 by using tin in smt (surface mount technology), and the upper end of the shielding cover 30 is laser-welded to the upper surface of the TYPE-C female socket 20.

Specifically, the shielding case 30 of the present embodiment includes a top plate 31, two side plates 32 and a rear plate 33, wherein the top plate 31 is disposed parallel to the PCB 10; both the side plate 32 and the rear plate 33 are perpendicular to the PCB 10, and the bottom surfaces of the side plate 32 and the rear plate 33 are attached to the PCB 10 through SMT. Roof 31 increases by preceding to back width gradually in shield cover 30 to the volume of increase rear end cavity, female seat 20 rear end of TYPE-C do not contact with shield cover 30, can avoid continuous tin.

Referring to fig. 1 to fig. 3, the TYPE-C socket 20 of the present embodiment is disposed in the cavity, and the TYPE-C socket 20 is soldered on the PCB 10. Specifically, the mode that female seat 20 of TYPE-C welds on PCB board 10 does: PCB board 10 is equipped with a plurality of welding hole 11, and female seat 20 bottoms of TYPE-C are equipped with a plurality of fillet weld 21, and fillet weld 21 contains DIP fillet weld 211 and SMT fillet weld 212, and SMT fillet weld 212 is located female seat 20 rear end of TYPE-C, and DIP fillet weld 211 inserts in welding hole 11, and SMT fillet weld 212 welds on PCB board 10 surface. The fixation was performed by two plate processes, DIP (dual inline-pin package) and SMT (surface Mounted technology).
