Claims

[Scope of Claim for Utility Model Registration] 1. A large-diameter head 11b for locking a rotary tool protrudes from one end position of a male threaded port tube portion 11a that can be inserted into the wiring port 12 of the wiring box B. A ground terminal 11 that also serves to prevent loosening is provided on the back of the head 11b.
The above-mentioned method comprises an adapter 11 having a protruding portion 11c, and a box-type coupling 13 for connecting a flexible conduit, which has a correspondingly formed female threaded cylindrical portion 13b that can be screwed into the male threaded cylindrical portion 11a of the adapter 11. The male threaded cylindrical portion 11a of the adapter 11 is screwed into the female threaded cylindrical portion 13b of the coupling 13 facing the wiring port 12 of the wiring box B from the outside, and the male threaded cylindrical portion 11a of the adapter 11 is screwed from inside. A conduit connecting device to a wiring box, characterized in that a ground terminal 11c is set so as to bite into the wall of the wiring box B. 2. A large-diameter head 11b for locking a rotary tool extends from one end position of the male threaded opening tube part 11a that can be inserted into the wiring port 12 of the wiring box B, and a loosening prevention device is attached to the back surface of the head 11b. Dual-purpose earth terminal 11
c, and a pipe-type coupling 19 for connecting a metal conduit tube, which has a correspondingly formed female threaded cylindrical part 19b that can be screwed into the male threaded cylindrical part 11a of the adapter 11, and the above-mentioned wiring. The male threaded cylindrical portion 11a of the adapter 11 is screwed and fastened from the inside to the female threaded cylindrical portion 19b of the coupling 19 facing the wiring port 12 of the box B from the outside, and the adapter 11 is connected to the ground. A device for connecting a conduit to a wiring box, characterized in that the terminal 11c is set so as to bite into the wall of the wiring box B. 3 Male screw cap tube part 11a in adapter 11
3. The conduit connection device for a wiring box according to claim 1, wherein the opening edge at one end is formed into an outwardly expanding conical surface 11d.
