Title:
ELECTRIC WIRE TUBE, ELECTRIC WIRE TUBE CONNECTION STRUCTURE, BELL BLOCK, METHOD FOR CONNECTING ELECTRIC WIRE TUBES, METHOD FOR CONNECTING ELECTRIC WIRE TUBE AND BELL BLOCK, TUBE JOINT, AND RING MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/082400
Kind Code:
A1
Abstract:
A region interposed between a pair of locking walls 9 becomes a ring member disposing part 11. The ring member disposing part 11 is formed so as to have a straight-tube shape parallel to the tube axis direction. A ring member 5 is disposed in the ring member disposing part 11. The ring member 5 has roughly a letter-C shape in which a circumferential part is open at an opening 19. One end side of the ring member 5 becomes a diameter-reduced part 21, the outer diameter of which is smaller than those of other parts. Second claws 23 are formed on the diameter-reduced part 21 toward the other end side of the ring member 5 so as to be disposed side by side but being separated from each other by slits 25 in the circumferential direction. First claws 22 project from the diameter-reduced part 21 roughly parallel to the tube diameter direction, and form a slide guide. The second claws 23 are each expanded in diameter so that the outer diameter gradually increases from the diameter-reduced part 21 toward the tip. A male fitting part 1a and a female fitting part 30a are connected to each other by using the ring member.
