Description

Folding pin structure of charger and charger Technical Field The utility model relates to the technical field of chargers, in particular to a folding pin structure of a charger and the charger. Background The foldable products of European and Korean plug and Brazil plug on the market commonly adopt a single-shaft hinged folding mechanism, and the plug body and the folding inserting sheet can continuously rotate by 0-90 degrees through the rotating shaft component. From the mechanical design perspective, the structure realizes the simplest design of the space displacement of the inserting piece through a single rotation degree of freedom, and the hinge part adopts a multi-piece hinge structure made of zinc alloy or stainless steel material and is matched with a ball bearing or a friction plate to reduce the rotation resistance. Although the structure can realize the conversion of space forms on a physical level, the plug and the circuit board are connected through the electronic wire welding, and when the plug (pin) rotates from 0 to 90, the electronic wire can be twisted, and as a result, the electronic wire is easy to break, and open circuit is generated. When the inserting sheet rotates, the electronic wire bears periodic torsional stress, so that plastic deformation and fatigue fracture of copper wires inside the wire core occur. Research shows that the torsional strength of a single strand copper wire tends to decrease nonlinearly with increasing diameter, while stranded wires tend to experience fretting wear between strands under frequent twisting. In addition, PVC or TPE insulating materials for the outer layers of the electron beam can develop stress relaxation and cracks after repeated deformation, further accelerating the failure of the inner conductor.
