JPS585372Y2 - Oil-proof and waterproof connector for coated flexible conduit - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a waterproof and oil-proof condenser for flexible electrical conduit covered with synthetic resin or the like.

Recently, synthetic resin (vinyl, etc.) has been applied to the outer periphery of flexible tubes in order to protect the wires inserted into high-conductor high-wire tubes (flexible tubes, class 2 flexible tubes, etc.) from oil, water, dust, etc. Recently, flexible tubes coated with rubber or rubber have come into widespread use.

However, the current situation is that there is no definitive product for the condenser at both ends used during installation, and users are having a hard time.

In particular, the present invention involves peeling off the coating on the end of the flexible tube, pushing a tightening nut, etc. into the end of the flexible tube, and then inserting a screw made of metal that screws into the spiral on the outer periphery of the flexible tube inside. An in-collar made of an elastic material baked into the head end is screwed along the outer circumferential spiral of the flexible tube, the end is flush with the inner collar, and the in-collar is pushed into the main body. The present invention provides a connector for a coated flexible conduit in which outer threads are screwed together, thereby contributing to waterproofing and oil-proofing.

Next, embodiments of the present invention will be described based on the drawings.

In Fig. 1, the connector basically consists of a joint body 2, a lock nut 3, an inner collar 1, an umbrella ring 5, and a cap nut 4.
, the bag nut 4 is the same as the known one, but the in collar 1, which is important in this invention, is as shown in Fig. 2.
The inner periphery of the metal collar 1 has a screw that screws into the outer circumferential spiral 12 of the flexible tube 6 when the coating of the coated flexible tube 6 is peeled off, and the head end is bent to the outside of the circumference. The ring 8 is made of an elastic material such as oil and water resistant rubber or synthetic resin and is baked into one piece.

Then, cut the end of the cut flexible tube 6 covered with vinyl or the like by about 1Qm/m, push the cap nut 4 and the umbrella ring 5 into the outer periphery of the flexible tube, and insert the inner collar 1 into the inner collar 1. The outer circumferential spiral 12 of the flexible tube 6 is connected through the inner circumferential screw 11 of the
Screw in while rotating from the head rubber part 8 along the inner collar 1 so that the end part is flush, then push the opposite side of the head rubber part 8 of this in-collar 1 into the inside of the joint body 2, and tighten the cap nut 4.
The inner thread 9 of the main body 2 and the outer thread 10 of the main body 2 are screwed together to assemble the connector as a whole.

Since the present invention is constructed in this way, it becomes a mechanism that can be grounded by screwing in the inner collar, and also because there is an inner thread inside the metal inner collar that screws into the spiral on the outer periphery of the flexible tube. Increases tensile strength.

Furthermore, since there is an elastic body baked into the head of the in-collar, it is effective for oil-proofing, waterproofing, dust-proofing, etc. by tightening.

It also has the advantage of having a small number of parts, making it easy to manage and assemble, and being completely fixed.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention, and FIG. 1 is an upper half vertical sectional view of the assembled drawing, and FIG. 2 is an upper half vertical sectional view of the main parts. In the drawing, 1 is the inner collar, 2 is the joint body, 3 is the lock nut, 4 is the tightening nut, 5 is the umbrella ring, 6 is the flexible tube, 7 is the inner circumference of the inner collar, and 8 is the inner circumference of the inner collar. Elastic parts, 9 are the inner threads of the nut for tightening, 10 are the outer threads of the joint body, 11 are the inner threads of the inner collar, 12 are the outer circumference spirals of the flexible tube, and 13 are the coatings.
