Patent number: 9839315Abstract: A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution systems can be disposed within the trunk sections. The power distribution systems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution systems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution system can engage the voids of another power distribution system without the need to rotationally align the tree trunk sections.Type: GrantFiled: March 25, 2016Date of Patent: December 12, 2017Assignee: POLYGROUP MACAU LIMITED (BVI)Inventors: Chi Yin Alan Leung, Chang Jun He, Chi Kin Samuel Kwok
