AI Technical Summary
The power PIN of the existing TYPE-C mother seat interface is separately derived from the ground PIN, resulting in complexity of PCB LAYOUT, which increases the design and manufacturing costs. At the same time, in special use scenarios, the medium steel sheet needs to design the welding foot and the PCB welding guide, which has a complex structure, which increases the cost and adverse risks.
A large current mother seat with a power PIN and grounding PIN connected structure is designed. Through the upper and lower terminal current PIN connected, only one power welding foot and one grounding welding foot are introduced. The middle steel sheet hook is bonded and connected to the upper and lower terminal shrapnel into a whole, forming a closed loop effect, simplifying the PCB LAYOUT and improving the current transmission capability.
It realizes simplified PCB LAYOUT, reduces design and manufacturing costs, improves current transmission capabilities, and achieves better ground shielding effects in special use scenarios.
