Description

Technical Field

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

[0002] Type-C is a USB interface standard that is smaller than 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 four pairs of TX / RX breakout lines, two pairs of USB D+ / D-, one SBU pair, two CC lines, four VBUS lines, and four ground lines.

[0003] The current Type-C connector's main structure includes an insulating body, a terminal assembly, and a shielding shell. The insulating body includes a base and a tongue extending forward from the base. The terminal assembly is mounted on the insulating body and has multiple contact portions and multiple soldering portions. The contact portions are exposed on the upper and lower surfaces of the tongue, and the soldering portions extend outside the base. The shielding shell covers the insulating body.

[0004] In the prior art, to achieve the waterproof function of the Type-C connector, its shielding shell generally adopts a seamless shell, and then a waterproof ring is set on the seamless shell, and glue is applied between the seamless shell and the insulating body. Although the Type-C connector of this structure can achieve waterproofness, its seamless shell is formed by stretching metal sheet, which is difficult to manufacture, expensive, and has a relatively low pass rate. In addition, because the shielding shell is metal and the insulating body is plastic, the glue bonding between the metal and plastic is easily affected by external environmental factors such as thermal expansion and contraction, causing separation, thus failing to achieve a good waterproof effect. Therefore, it is necessary to improve the current Type-C connector. Utility Model Content
