Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 to 7 illustrate a connector for copper pipe connection according to the present invention, which is for interconnecting one main pipe 1 made of the same material and two branch pipes 2.

According to this, the copper pipe connection connector is formed in the shape of a tubular body extending in the lateral direction and has a coupling hole (11) through which the main pipe (1) is inserted and formed at one end, (10) having a branch hole (12) in which the two branch pipes (2) are inserted and a branch pipe (12) connected to the branch pipe (12) And a sealing member (20) sealing the gap between the engine (2).

In detail, the connection tube 10 is manufactured by press-molding a pipe of a copper material extending in the lateral direction using a metal mold.

At this time, the coupling hole 11 has an inner diameter corresponding to the outer diameter of the main pipe 1, and after the main pipe 1 is coupled to the coupling hole 11, the main pipe 1 is inserted into the coupling hole 11 Can be welded.

The branch hole 12 is formed to have a diameter corresponding to the outer diameter of the branch pipe 2 and has a pair of semicircular curved portions 12a formed so as to be opposed to each other on the upper and lower sides and both ends of the curved portion 12a And a pair of rectilinear sections 12b connected to each other.

The width of the branch hole 12 in the vertical direction is longer than twice the diameter of the branch pipe 2 so that the periphery of the branch pipe 2 is closely contacted with the curved portion 12a. When the engine 2 is drawn into the branch hole 12, the branch pipes 2 are configured to be spaced apart from each other in the vertical direction.

The sealing member 20 is formed in the shape of a block having both side widths equal to the outer diameter of the branch pipe 2 and semicircular recessed grooves 21 corresponding to the outer diameter of the branch pipe 2 on the upper and lower sides thereof do.

5 and 7, when the sealing member 20 is coupled to the branch hole 12, the branch pipe 2 is bent by the concave groove 21 and the curved portion 12a, Two circular holes H to be joined are formed.

At this time, the sealing member 20 is made of a copper material and is welded to the joint tube 10 and the branch pipe 2 at a peripheral portion thereof, and is composed of a metal having a higher strength than copper And the welding block 22 is coupled to the branch hole 12 so as to face the outside of the connection tube 10. [

The welding block 22 is made of the same copper material as the coupling tube 10 and the branch tube 2 so that the peripheral portion is welded to the coupling tube 10 and the branch tube 2.

The support block 23 is configured to reinforce the strength of the sealing member 20, which is made of a metal having a higher strength than the copper material, preferably a steel material having a high strength and a magnetic material, ).

Preferably, the thickness of the welding block 22 and the support block 23 may be in a ratio of 1: 3.

The sealing member 20 is coupled to the branch hole 12 of the connection tube 10 and the branch tube 2 is connected to the hole H formed in the connection tube 10 and the sealing member 20, The welding block 22 of the connection tube 10 and the branch tube 2 and the connection tube 10 can be welded to each other and tightly coupled to each other.

The connector for the hose connector thus constructed is formed in the shape of a tube of a copper material extending in the lateral direction and has a coupling hole 11 through which the main pipe 1 is inserted at one end and a long hole extending in the vertical direction at the other end A connection tube 10 formed with a branch hole 12 into which the two branches 2 are inserted and a branch tube 12 connected to the branch hole 12 so as to be positioned between the branches 2, The connector 1 can be manufactured at a lower cost than the connector made of the copper material manufactured by the casting method, and the main pipe 1 and the branch pipe 2 can be firmly fixed to each other There is an advantage that it can be fixed.

Particularly, the branch hole 12 is formed to have a diameter corresponding to the outer diameter of the branch pipe 2 and has a pair of semicircular curved portions 12a formed to be opposed to each other on the upper and lower sides, And a pair of linear portions (12b) connecting both ends of the branch pipe (12). The width of the branch pipe (12) in the vertical direction is longer than twice the diameter of the branch pipes (2) And the upper and lower sides thereof are formed with semicircular concave grooves 21 corresponding to the outer diameter of the branch pipe 2 so that the sealing member 20 A circular hole H in which the branch pipe 2 is engaged is formed by the concave groove 21 and the curved portion 12a.

The sealing member 20 is coupled to the branch hole 12 of the connection tube 10 and the branch tube 2 is coupled to the two holes H formed in the connection tube 10, Since the sealing member 20 and the branch pipe 2 can be welded to each other, there is an advantage that the operation is very easy.

The sealing member 20 includes a welding block 22 made of copper and welded to the joint tube 10 and the branch pipe 2 at a peripheral portion thereof and made of a metal having a higher strength than copper And the welding block 22 is coupled to the branch hole 12 so as to be positioned between the branch pipes 2 so as to face the outside of the connection tube body 10. [

Therefore, the welding block 22 can be welded to the sealing member 20 and the branch pipe 2 in an airtight manner, and the strength of the sealing member 20 is improved by the supporting block 23, There is an advantage that both end portions of the concave groove 21 formed in the sealing member 20 can be prevented from being bent and deformed when the member 20 is transported or stored.

That is, the copper material is relatively low in strength and can be easily deformed by an external force.

Meanwhile, the sealing member 20 has concave grooves 21 on both sides thereof, and both ends of the concave grooves 21 are protruded to be sharp.

Therefore, when the entirety of the sealing member 20 is made of the same material, the pointed portions at both ends of the sealing member 20 are bent inward or outward, May not be inserted or the sealing member 20 may not be inserted into the branch hole 12. [

In order to solve such a problem, the method of constructing the sealing member 20 with high strength steel may be limited. However, in general, the steel is welded to the connection tube 10 or the branch pipe 2 made of the same material, .

The sealing member 20 is formed by laminating a welding block 22 made of the same material and a supporting block 23 made of a metal having a strength higher than that of copper, The sealing block 20 is welded to the connection tube 10 and the branch pipe 2 and the support block 23 functions to reinforce the strength of the welding block 22. As a result, ) And the branch pipe (2), and at the same time, the sealing member (20) can be prevented from being deformed by an external force.

8 and 9 illustrate another embodiment according to the present invention, wherein a magnet member 30 is further provided inside the end of the branch pipe 2.

The magnet member (30) is formed in a cylindrical shape whose outer diameter is slightly smaller than the inner diameter of the branch pipe (2).

As shown in Fig. 8, after the magnet member 30 is inserted into the end portion of the branch pipe 2, the connector for connecting copper pipes constituted as described above is inserted into the end portion of the branch pipe 2, When the end of the engine 2 is inserted into the concave groove 21 of the sealing member 20, the branch pipe 2 is moved by the magnetic force of the magnet member 30 to the supporting block of the sealing member 20 The sealing member 20 and the branch pipe 2 can be welded and fixed to each other while the branch pipe 2 is attached to the concave groove 21 of the sealing member 20 have.

When the sealing member 20 and the pair of branch pipes 2 are welded and fixed to each other, the magnet member 30 is removed and the sealing member 20 and the branch pipe 2, which are welded to each other, The branch tube 2 can be coupled to the connection tube body 10 by inserting the branch tube 2 into the branch tube 12 of the connection tube 10 and then welding it to the connection tube body 10.

Therefore, there is an advantage that the branch pipe (2) and the sealing member (20) can be more easily coupled to the branch hole (12) of the connection tube body (10).
