Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a waterproof TYPE-C connector. Background Art

[0002] Among various mobile devices and PCs, Type-C connectors have become the data interface connectors with the broadest development prospects, and have a wide range of market demands at home and abroad. Among them, the EU requires TYPE-C connectors to meet EN IEC 62680-1-3:2021 certification, and many brands of mobile phones require TYPE-C connectors to meet USB IF certification. TYPE-C sockets usually have two structures. One is an iron shell with a shrapnel. However, the iron shell with a shrapnel in TYPE-C cannot be sealed, and the waterproofing will fail. It does not meet the waterproofing requirements and therefore cannot meet the certification requirements; the other TYPE-C connector is 300, such as Figure 3 As shown, it is through the TYPE-C tongue (ie, the rubber core component 200, such as Figure 2 As shown in FIG. 1 ), an EMC PAD (Electromagnetic Compatibility Pad) is added, that is, a shielding metal sheet 100 is added, such as Figure 1 As shown, the whole is in sheet shape. The traditional EMC PAD is a single metal spring mold, which is then assembled and installed on the tongue piece for in-mold injection molding. When the EMC PAD is not assembled or assembled in an offset position, the plastic mold is prone to plastic encapsulation or compression molding, and the quality of the product cannot be effectively guaranteed. At the same time, the EMC PAD needs to be connected to the outer iron shell, which causes the EMC PAD to be higher than the plastic surface. In the waterproof TYPE-C, there is a risk of glue overflowing to the tongue piece after dispensing. Therefore, R&D personnel are urgently needed to improve the above problems. Utility Model Content
