An improved swivel coupling for the parts of electrical appliances
Реферат: 583,199. Two-part couplings; swivelling couplings. HALLIDAY, W. M. June 30, 1944, No. 12468. [Class 38 (i)] An adjustable coupling for parts of electrical appliances, e.g., lamps, comprises a casing formed by two circular parts, 1, 2 enclosing a hollow space for the electrical coupling contacts 15, 16, 20, 21, a fibre or like frictional ring between the parts 1, 2, a central pivot pin 3 connecting the two parts and spring washers 6, 9 and nut 8 for resiliently pressing the parts 1, 2 together. Concentric ring contacts 15, 16 carried by an insulating disk 13 are engaged by clip contacts 20, 21 on a disk 19. The end of the pin 3 adjacent to the nut 8 is of D-section to prevent rotation of the pin in part 1. Studs 17, 23 connect the contacts with the leads 18, 22.
