Claims

[Scope of Claim for Utility Model Registration] 1. A joint body 15 that receives the cut end of the flexible conduit 11 in the large diameter threaded cylinder part 18, and is screwed into the large diameter threaded cylinder part 18 of the joint body 15 in a crowned manner. In a joint for a flexible electrical conduit including a cap nut 20 to be fastened, a spiral strip 19 is provided on the inner circumferential surface of the large-diameter threaded cylinder portion 18 to engage with the metal helical tube 12 of the flexible electrical conduit 11.
The cap nut 20 is molded from hard synthetic resin or rubber, and an elastic packing 21 that can be pressed against the outer circumferential surface of the conduit 11 is attached and attached to the bag portion of the nut 20 in a continuous manner. Fittings for flexible electrical conduits. 2. The elastic packing 21 is installed in the bag portion of the bag nut 20 in an inwardly folded state, and the elastic packing 21 is provided with an inclination gradient of a constant angle θ that gradually protrudes inwardly toward the tip of the fold, and the radial split grooves 22 2. The flexible electrical conduit joint according to claim 1, wherein the elastic packing 21 is shaped into a plurality of tongues or claws by providing a plurality of tongues or claws.
