Abstract: The present invention provides a cable installation method and a coupling unit, the cable installation method enabling the installation of a cable with an improved workability. From a messenger wire 11 installed between poles 10a and 10b, a spiral hangar unit 121 or the like is suspended in the vicinity of first pole 10a, the leading end of the spiral hangar unit 121 and the leading end of the lead wire 13 is connected to each other with a coupling unit 14 interposed therebetween an operation of connecting another spiral hangar unit 122 to a tail end of the spiral hangar unit 121 while feeding the lead wire 13, is repeated, the spiral hangar unit 121 is fed to the vicinity of second pole 10b, then the spiral hangar 12 is fixed to the messenger wire 11, and thereafter a cable 16 is installed between the poles.

Abstract: A clamp includes a first member, a second member, and a fastener. The first member has a first connecting portion and a first supporting portion. The second member has a second connecting portion and a second supporting portion. The first connecting portion and the second connecting portion are twisted clockwise or counterclockwise such that a first clamping portion of the first connecting portion and a second clamping portion of the second connecting portion are tilted to the right or to the left with respect to a front-back direction when seen from above. A spiral hanger is mounted on a support wire by tightening the first member and the second member by the fastener in a state where a support wire is passed through between the first supporting portion and the second supporting portion and a spiral hanger is passed between the first clamping portion and the second clamping portion.

Abstract: A new cable installation tool for installing a new cable between two points where the existing support line is installed includes: a plurality of S-shaped guides; a connection rope that connects the plurality of S-shaped guides; and a towrope that is bound to the end of the connection rope.

Abstract: A socket fixed to a heat sink holds a card-type LED module formed by integrating LED elements. The socket (6) includes: a frame structure for holding the LED module (1000) with its light source unit exposed through the frame opening; and a pressing member positioned around the opening for pressing the back surface of the LED module against the heat sink (2122). The socket may include a structure including a lower member (61) placed on a heat sink and an upper frame member (62) holding the LED module with its light source unit (1002) exposed through the frame opening. The upper member supported by the lower member via a hinge can open/close, and includes a pressing unit pressing the LED module set in the open state, against the lower member (61). The lower member (61) includes, in its main part, a lock unit (63) directly or indirectly lock the upper member (62) when the upper member is closed.
