Description

Technical Field

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

[0002] With the development of electronic products, the USB Implementers Forum has set the TYPE-C interface as the unified interface for all electronic products, aiming to reduce the types of interfaces of electronic products and avoid material waste. According to the regulations of the USB Implementers Forum, the TYPE-C interface has many functional pins (also called functional terminals), and these functional pins each perform their own duties. Among them, the configuration pins (CC1 / CC2, VCONN) are used to detect and identify the connected device, and usually the functional resistors connected to the configuration pins are used to distinguish the device types (Source, Sink, DRP). For example, the pull-up resistor (Rp) and the additional resistor (Ra) are used at the host side to enable the device to identify the connected peripheral device; the pull-down resistor (Rd) and the additional resistor (Ra) are used on the peripheral device to help the device perform role identification and power management. In addition, for USB PD, the CC line can also transmit higher power levels and alternate modes.

[0003] In the prior art, the common practice is to pre-weld the functional resistor on a PCB board and then connect the PCB board to the configuration pins. This method has the problems of requiring an additional PCB board, which increases the material cost on the one hand and the processing cost on the other hand; moreover, when the TYPE-C interface is used as a USB PD interface, the thickness of the copper foil of the PCB board also limits the passing of large currents and affects the transmission of higher power levels.

[0004] In order to solve the above problems, Chinese patent document CN 216872298 U discloses a TYPE-C connector, which omits the PCB board and sets the pull-up resistor and the pull-down resistor on the connector body, and the pull-up resistor and the pull-down resistor are directly connected to the configuration pins of the connector. However, although this TYPE-C connector does not require an additional PCB board to carry the functional detection resistor, this TYPE-C connector still has the problems of poor waterproof performance and relatively complex structure.
