Electronic Design - ​A low-cost, high-current type-c connection PCB

This utility model belongs to the technical field related to the c-type connector, and relates to a low-cost, high-current type-c-type connector circuit board.

Background technique.

USB Type-C abbreviated as USB-C is a hardware interface specification of Universal Serial Bus (USB). The highlight of the new interface is a thinner design, faster transmission speed (10GBP) and more powerful power transmission (100W). The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, and officially solves the uncertain problems in the world. At the same time, the compatible USB data cable must be thinner and lighter.

The existing c-type connector circuit board technology has the following problems: the prior art c-type connector circuit board connection pin design usually adopts two methods. First, the four conductors are connected to the front and rear VBUS pins respectively, and then the welding of the conductors is summarized, so as not to affect the diameter of the beautiful conductor. In order to avoid damage, the connector is prone to heat and burn out. The efficiency of charging current and voltage needs to be further limited. Use a new board to connect the upper and lower VBUS pins, then use two wires to connect to the new board, then solder and summarize. This method increases the overcurrent allowed by the diameter of the connecting conductor, but at the same time also increases the cost of the two-layer board.
