Title: Motor-driven lifting device
Inventor: SUZUKI KEIZO
IPC: H01R13/03
Filed: 1991-07-25
Abstract: PURPOSE:To reduce wear due to an arc by covering mutual contacting surfaces between a feeding contact and a receiving contact with contacting layers of a silver cadmium oxide in such a manner that the thickness of the contacting layers on the feeding contact is larger than that on the receiving contact. CONSTITUTION:Contacting layers 62 and 82 are made of silver cadmium oxide; the thickness B of the layer 62 on a feeding contact 31 is designed to be larger than that C of the layer 82 on a receiving contact 73. The contact 73 contacts with the contact 31; the contact 73 is pushed and contacted with the contact to be connected to a power supply while moving downward against a spring 74. When the lifting of the illuminating equipment is performed without turning the power supply to a motor lifting device off, an arc takes place between the contacts accompanying the contacting and leaving between the contacts 31 and 73. But, since the layers 62 and 82 made of the silver cadmium oxide are resistive against the arc, the waste of the contacts 31 and 73 due to at arc can be reduced by the protecting action of the layers 62 and 82 so that the life of these contacts 62 and 82 can be enhanced.
