Description

Technical Field

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

[0002] The USB TYPE-C connector is a USB interface appearance standard that is smaller than both TYPE-A and TYPE-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB TYPE-C has 4 pairs of TX / RX breakouts, 2 pairs of USBD+ / D-, a pair of SBU, 2 CCs, 4 VBUS and 4 ground wires. On October 4, 2022, local time, the European Parliament passed a bill with an overwhelming majority. The bill stipulates that from the end of 2024, all new portable smart devices must use USB TYPE-C connectors; from 2026, USB TYPE-C connectors will also become the standard interface for laptop chargers. In October 2022, Apple confirmed on the 25th that it would comply with EU requirements and that all smartphones would use USB TYPE-C connectors from 2024.
