Description

Tube Connector {Tube Connector}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated pipe connector, and more particularly, to a connector that is assembled and connected to each other inside and outside a piping box.

Generally, most of the wires that are wired in a building are protected by being inserted into a conduit, and a conduit is mainly used for the purpose of ease of operation and the like. When such a flexible conduit is connected to an electric wiring box, a conduit connector is used. A conventional conduit connector is shown in Fig.

Referring to FIG. 1, a conventional wire connector 10 has a cylindrical shape and a through-hole. One end of the wire connector 10 is formed with a male screw portion 12 having a fastening step 11, And a fastening band 13 having a screw hole for fastening the screw S so as to surround and fasten the flexible conduit F to be inserted. When connecting the flexible conduit to the electric wiring box using such a conduit connector, the flexible conduit in which the wire is inserted is inserted into the conduit band side of the conduit connector, and then a screw inserted in the screw hole is tightened using a separate tool, And then the male screw portion is inserted into the inlet of the electric wiring box and the nut is fastened inside the electric wiring box to fix the conduit connector to the electric wiring box.

However, since the conventional conduit connector needs to tighten the screws so that the fastening band covers the flexible conduit when fixing the flexible conduit to the conduit connector, the efficiency of connecting the conduit with the flexible conduit is inferior have. That is, not only a separate tool is required to tighten the screws but also a long time is required for tightening the screws.

In addition, it is often the case that the screw of the fastening band to which the flexible conduit is fixed is loosened with time and the flexible conduit is detached from the fastening band. As a result, the electric wire inside the flexible conduit is exposed to the outside, There was a problem that a safety accident such as an accident occurred.

A technique related to a conduit connector capable of easily connecting a conduit to a conduit connector has been disclosed in Korean Patent No. 432471 (conduit connector, hereinafter referred to as prior art). 2, when the diameter is contracted due to an external pressure and the external pressure is removed, the diameter of the wire is elastically enlarged and returned to be circularly inserted into the branch hole 21 of the electric wiring box 20 A fitting band portion 14 having a cutout portion 13 between the end portions and formed with an insertion groove 15 in which an end of the branch hole 21 of the electric wiring box 20 is fitted and fixed to the outer periphery, When the diameter is increased and the external pressure is removed, the diameter of the fastening band portion 16, which is bent in a circular shape so as to be tightened around the flexible conduit F while being resiliently resiliently resiliently restored, is crossed by the connecting band portion, .

However, in the conventional conduit connector thus constructed, a separate tool such as a bench for enlarging the diameter of the fastening band portion is required, and the construction is complicated, which makes it difficult to manufacture. In addition, since the fitting groove is formed to have a small width, there is a limit in that the conduit connector can be fixed to the branch hole of the electric wiring box only when the thickness of the electric wiring box is thin. Therefore, there is a problem that it can not be used in an electric wiring box having a thickness exceeding a limited thickness.
