The present proposal relates to a connection device for electric wiring pipes for protecting electric wires, and more specifically, to easily connect pipes without forming a thread at the connection portion.

In general, in order to supply electricity to a machine or a lamp, it is possible by wiring using a wire, and at this time, the wire is installed in a pipe to protect the wire.

Pipes for protecting electric wires are roughly divided into plastic pipes and metal pipes. When laying electric wires when building or expanding a building, plastic pipes are mainly used since there is no risk of damage to the pipes due to impact. When the electric wire is installed to the outside of the floor or the wall as in the back, a metal material is used to prevent the pipe from being broken by the weight.

The metal pipes (hereinafter, referred to as "pipes") are cut into appropriate lengths according to the shape of the wiring and interconnected with separate connectors.

Conventionally, male threads 1a are formed at both ends of the cut pipe 1 as shown in FIG. 1 to interconnect the pipes with a connection port, and female screws 2a are formed inside the connection port 2 so as to interconnect them. The connection work is completed by screwing together.

However, in the conventional apparatus, a male screw 1a must be formed at the connection portion of the pipe 1 in order to cut and interconnect the pipes 1 according to the shape of the wiring. There was a problem such as a decrease in work efficiency.

The purpose of the present invention is to solve such problems in the related art, and to improve the efficiency of work by making it possible to easily connect the connection part of the pipe to the connection port without using a separate screw molding machine.

According to this aspect of the present invention for achieving the above object, to form a slope that becomes narrower toward the inner side in the connection port for interconnecting pipes, and a plurality of cutouts at the same time to form a slope corresponding to the connection port in the fixture for coupling the pipe and the connection port Forming a pipe is fitted into the fixture and coupled with the connector and then connected to the pipe for the electrical wiring provided by fixing them with screws through the fastening hole formed in the connector and the fixture.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 2 and 3 of the accompanying drawings.

FIG. 2 is an exploded perspective view showing a part of the present security device in a cutaway view, and FIG. 3 is a longitudinal cross-sectional view of the connection state of the device according to the present invention, and is narrower toward both sides of the connection port 12 connecting the pipes 11 with each other. The inclined surface 12a is formed, and the fastener 13 which joins the pipe 11 of the metal material and the connector 12 has an inclined surface 13a having a slope corresponding to the connector 12, that is, a diameter toward the inside. The inclined surface 13a which becomes small is formed, and the several notch part 13b is formed in the circumferential surface.

In this case, the reason for forming the notch 13b on the circumferential surface of the fixture 13 is that when the pipe 11 is pushed into the connector 12, the fixture 13 is also pushed into the connector 12 together with the pipe 11. This is to allow the inlet side of the fixture 13 to be retracted inward by the inclined surfaces 12a and 13a to firmly support the pipe 11.

On the other hand, a step 13c is formed at the inner end of the fastener 13 so that the end of the pipe 11 is connected, and fastening holes 14 and 15 are formed at the connection hole 12 and the fastener 13, respectively. The pipe 11 is inserted into the fixture 13 and pushed into the connector 12, and then the screws 16 are fastened through the fastening holes to fix them.

The operational effects of the proposed paper thus constructed are as follows.

First, the pipe 11 is cut to an appropriate length according to the shape of the wiring, and then in order to interconnect them, the fastener 13 is inserted into the connection part of the pipe 11 and the pipe 11 having the fastener 13 inserted therein is inserted. The connector 12 is pushed in the direction of the arrow of FIG.

Accordingly, the pipe 11 is fitted into the connector 12 in a state in which the pipe 11 is connected to the step 13c of the fixture 13, and the fixture 11 is inclined by the inclined surface 12a of the connector 12 and the inclined surface 13a of the fixture 13. 13 to support the pipe 11, wherein the more the insertion portion of the fixture 13, the greater the bearing force of the pipe 11 by the inclined surface and this operation is a cutout formed in the fixture 13 It is made more smoothly by (13b).

In this way, the pipe 11 may be separated from the connection part 12 by an external impact or the like in the state in which the pipe 11 is coupled to the connection hole 12, and thus, a fastening hole formed in the connection hole 12 and the fixture 13 ( 14) (15) by connecting the screw 16 is to complete the connection of the pipe (11).

As described above, the device of the present invention forms the inclined surfaces 13a and 12a on the fixture 13 and the connector 12, and the fixture 13 is connected to the connector 12 in a state where the pipe 11 is inserted into the fixture 13. Since the connection work is completed by pushing in, it is not necessary to form a male screw in the connection portion of the pipe 11, thereby having the effect of greatly improving the work efficiency.

Claims (2)
