PURPOSE:To raise the versatility and reduce the cost by standardization of parts, by furnishing three supporting insert holes at the joint part, and arranging a contact piece in connection with a power cord within each supporting insert hole. CONSTITUTION:A jointing member 1 is composed of a body 9 consisting of resin mold etc. having three parallelly oriented supporting insert holes 2-4, wherein the body 9 is coupled with a socket, into which a lamp is fitted to constitute a lighting construction. A pair of contact pieces 5, 6 in contact with power cords 7, 8 are fixed in this body 9, and one each of the contact pieces 5, 6 is installed in the central supporting insert hole 3 in such a way as facing, while the others of the contact pieces 5, 6 are arranged in the supporting insert holes 2, 4 on both sides. In case there is only one stay 10, it is inserted in the central insert hole 3 to bear the lighting construction, together with making connection electrically, and in case there are two stays 11, they are inserted in the insert holes 2, 4 on both sides to support the same together with electrical connection. This enables fitting of the lighting construction using the same parts irrespective of the number of stays to achieve simplified electrical connection. |
