<P>PROBLEM TO BE SOLVED: To achieve a coupler for illumination fixtures in which a plurality of illumination fixtures can be radially coupled and in which adjustment of coupling angles can be carried out. <P>SOLUTION: The coupler includes a first arm part 16 to a fourth arm part 22 that are arranged at 90° spacing, in which a pair of contact pins 23a, 23b are formed in the first arm part 16 and the second arm part 18, and in a third arm part 20 and a fourth arm part 22, a pair of arc-shape long holes 30a, 30b are formed that are extended in the longitudinal direction of these arm parts 20, 22 and oppositely arranged at 180° spacing on the same circumference. In the long holes 30a, 30b of the third arm part 20, conductor patterns 34c, 34d, that are electrically connected to the contact pins 23a, 23b of the second arm part 18 are extendedly installed, and in the long holes 30a, 30b of the fourth arm part 22, conductor patterns 34a, 34b that are electrically connected to the contact pins 23a, 23b of the first arm part 16 are extendedly installed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
