BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 1 is a perspective view showing a state of use of a car audio connection pipe provided with a transparent window according to the present invention, FIG. 2 is a perspective view showing a car audio connection pipe provided with a transparent window according to the present invention, FIG. 4 is a view showing a state where a sound insulating layer is formed on the surface of the transparent connection tube of FIG. 3, and FIG. 5 is a sectional view taken along the line AA of FIG.

As shown in FIG. 1, a car audio connection pipe 100 having a transparent window according to the present invention is used to connect a pipe 10 and a pipe 10 during a sewer piping work.

The connection pipe 100 of the present invention used to connect the pipe 10 and the pipe 10 as described above can be formed into various shapes such as 'I' type, 'L' type, and 'T' type, The embodiment of the present invention will be described as a 'Y' type coupling pipe 100 as shown in FIG.

2, the connecting pipe 100 according to the present invention is formed with an expanded portion 102 for inserting a pipe 10 on both sides of a body, and cap fastening portions 114 are formed on both ends of the body, And a Y 'type connection pipe 100 is formed by branching the branch pipe 101 at the center of the body.

Of course, the tubular portion 102, the cap fastening portion 114, and the connection port 113 are also formed at the end of the branch pipe 101 of the 'Y' type connection pipe 100.

A transparent window 103 is formed in the expanded portion 102 formed on both sides of the body of the connection pipe 100 and the expanded portion 102 formed in the end of the branched pipe 101 so that the transparent window 103 The inside of the expansion portion 102 can be visually inspected.

Therefore, when inserting the pipe 10 into the connection port 113 of the connection port when the water supply and drainage piping operation is performed, whether or not the pipe 10 is inserted to the end of the expansion pipe 102 is visually checked by the operator through the transparent window 103 So that it is possible to prevent the construction from being made.

3, the transparent connection pipe 110 is formed by injection molding a transparent synthetic resin as shown in FIG. 3. The transparent connection pipe 110 is formed through double injection as shown in FIG. 4, The sound insulating layer 120 is formed on the outer surface of the insulating layer 120.

The transparent connection pipe 110 may be made of a plurality of transparent synthetic resins, but it is preferable to form the transparent connection pipe 110 using a PVC resin having excellent processability and various mechanical properties.

And the noise of the fluid flowing through the inside of the transparent connection pipe 110 of the sound insulating layer 120 is transmitted to the outside.

5, when the sound insulation layer 120 of opaque material is formed on the outer surface of the transparent connection pipe 110 through the double injection, the sound insulation layer 120 is formed at the point of the expansion portion 102 of the transparent connection pipe 110, Thereby forming an opening 121 in which the opening 120 is not formed.

When the sound insulating layer 120 of an opaque material is formed on the outer surface of the transparent connection pipe 110 as described above, the opening portion 121 where the sound insulating layer 120 is not formed is formed on the body portion of the transparent connection pipe 110 ).

As described above, a part of the sound-insulating layer 120 is opened in the expanding part 102, so that the inside of the expanding part 102 can be visually observed through the opening part 121 and the transparent connection pipe 110, (103) are formed. A part of the sound insulating layer 120 is opened in the middle part of the transparent connecting pipe 110 so that the inside of the connecting pipe can be visually observed through the opening 121 in the middle part of the body and the transparent connecting pipe 110, A transparent window 104 is formed.

Therefore, it is possible to visually confirm whether or not the pipe 10 is correctly fastened through the expanding part transparent window 103, and it is possible to visually confirm through the body transparent window 104 whether or not foreign substances are deposited and blocked in the connection pipe during use Maintenance and maintenance are very easy.

The sound-insulating layer 120 may be formed of 30 to 60 parts by weight of a PVC resin, 2 to 3 parts by weight of a heat stabilizer, 20 to 35 parts by weight of DOP (di-octyl phthalate), 15 to 40 parts by weight of mica, And 3 to 10 parts by weight of the pigment are mixed to block the noise of the fluid flowing inside the connection pipe 100 from being transmitted to the outside.

And 2 to 3 parts by weight of a heat stabilizer are mixed. The heat stabilizer is mixed with 2 to 3 parts by weight to prevent damage to the PVC resin, improve workability and prevent deterioration. These heat stabilizers use known heat stabilizers.

And 20 to 35 parts by weight of plasticizer are mixed. DOP (di-octyl-phthalate) used as the plasticizer is used to improve properties such as hardness and viscosity of PVC, and is mixed with 20 to 35 parts by weight to give flexibility of the resin.

The mica is mixed with 15 to 40 parts by weight of the mica. The mica ensures the dispersibility of the PVC resin to be constant so that the resin flows smoothly during the molding of the product, thereby improving the dimensional stability and productivity. According to the content of the mica, the strength of the sound insulation effect, the impact strength and the tensile strength can be increased, so that deformation and breakage of the connection pipe 100 due to the external impact can be prevented, and cold weather is prevented.

Particularly, the mica increases the bonding property between the transparent connection pipe 110 and the sound-insulating layer 120 so that the interface between the transparent connection pipe 110 and the sound-insulating layer 120 is peeled off, It plays a role.

It is preferable that the mica is mixed with 15 to 40 parts by weight in consideration of product molding and unit cost of raw materials.

According to the present invention configured as described above, the transparent connection pipe 110 is formed in the form of a connection pipe 100 by injection molding a transparent synthetic resin, and the sound insulation layer 120 is formed on the outer surface of the transparent connection pipe 110 formed through the double injection A transparent window 103 is formed in the expanded portion 102 of the connection pipe 100 into which the pipe 10 is inserted so that the inside of the pipe can be visually confirmed. It can be visually confirmed whether or not it is fully inserted into the housing 100, thereby preventing a bad construction.

Further, since the degree of accumulation of foreign matter and the degree of clogging can be confirmed through the body transparent window 104 in the middle part of the connector tube, maintenance and repair are easy.

In addition, since the sound insulating layer 120 is formed outside the transparent connection pipe 110, it is possible to prevent the flow noise of the fluid flowing inside the connection pipe 100 from being transmitted to the outside, The interface between the pipe 110 and the sound-insulating layer 120 is not peeled off from each other, so that the car-sound reliability is high.

Hereinabove, the car audio connection pipe having the transparent window according to the present invention and the manufacturing method thereof have been described.

It will be understood by those skilled in the art that the technical features of the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, Ranges and equivalents thereof are to be construed as being included within the scope of the present invention.
