In FIG. 4, this dissimilar pipe joint 1 is for connecting a steel pipe, a box, a joint or the like (not shown) to the corrugated pipe 2. The joint body 1A of this dissimilar pipe joint 1 has a corrugated pipe. A corrugated pipe receiving port 1a into which 2 is fitted, a threaded portion 1b formed on the outer periphery on the opposite side, and a stopper portion 1c are formed in the middle. Also, the corrugated pipe receptacle 1 of this joint body 1A
The a is provided with an outward projection 3 and a window 4 aligned with the projection 3 in the axial direction. On the other hand, a claw plate 5 corresponding to each of the projection 3, the window 4 and the valley 2a of the corrugated tube 2 is separately formed, and the claw plate 5 has a projection insertion hole 6 and a claw 7 with the tip downward. And form.

取付けられる。Therefore, in this heterogeneous pipe joint 1, first, the hole 6 of the plate 5 with the claws is inserted into the projection 3 of the joint body 1A, and the claw 7 is inserted from the outside of the window 4 so that the tip of the claw is corrugated. -Slightly project from the inner peripheral surface of the inlet 1a for a pipe. Next, the head of the protrusion 3 is crimped to fix the joint body 1A and the plate 5 with the claws. Therefore, when the corrugated tube 2 is pushed into the corrugated tube receiving opening 1a, the corrugated tube 2 is pushed against the claw 7 and the end of the corrugated tube 2 contacts the stopper portion 1c. At the point of contact, the claw 7 fits into the valley 2a of the corrugated tube 2. Then, the dissimilar pipe joint 1 is attached to the corrugated pipe 2.

If a flexible O-ring is interposed between the corrugated pipe 2 and the dissimilar pipe joint 1 to form a waterproof dissimilar pipe joint,
There was a problem that the edge portion 7a was caught in the O-ring and could not be pushed into the corrugated tube 2, or the O-ring was damaged.

When the diameter is 0 mmφ, the number of the second screw screw holes 15 is four, and when the nominal diameter is 50 mmφ, it is 3 as shown in FIG.
Although the number is set (see the chain line in FIG. 1), the raised seat portion 20 is formed because the thickness is thin in the case of 50 mmφ. Any of the second screw screw holes 15 is formed on the extension side of the window 4 or the first screw screw hole 8 in the heterogeneous pipe joint 1,
It is easy to handle. Then, the fixing screw 19 is screwed into the second screw screw hole 15 to fix the electric wire tube 14.

A leaf spring 9 with a claw is placed on the outer surface of the corrugated tube receiving opening 1a of the joint body 1A and fixed with a screw 12. At that time, the claw 11 of the leaf spring 9 with a claw is inserted into the window 4, and the tip of the claw projects from the inner peripheral surface of the receiving port 1a. Then, the first O-ring 13 is fitted into the valley portion 2a of the corrugated pipe 2, and the corrugated pipe receiving port 1a of the dissimilar pipe joint 1 is externally fitted into the corrugated pipe 2 and pushed. At this time, the tip of the V-shaped claw 11 has not only the ridge portion 2b of the corrugated tube 2 but also the flexible first O-ring 13.
Since the base portion of the leaf spring 9 with the claws rides over while curving outward, the corrugated tube 2 is in contact with the stopper portion 1c until it comes into contact.
Can be pushed. Then, when the claw 11 fits into the valley 2a, the dissimilar pipe joint 1 is attached to the corrugated pipe 2.

Even if it is configured as a screwless conduit, a waterproof type dissimilar pipe joint can be obtained. Moreover, since the leaf spring is V-shaped, the first ring-shaped seal is formed when the corrugated pipe and the dissimilar pipe joint are connected.
It is possible to insert and connect smoothly without damaging the cable material. Also, when connecting the conduit and the dissimilar pipe joint,
Since a set screw is used, the thread cutting work can be omitted, and the strength of the conduit does not deteriorate because it is a screwless conduit.
