Description

Structure of CO2 welding cable {THE STRUCTURE OF CO2 WELDING CONNECTION CABLE}

The present invention is registered utility model registration No. 0208866 carbon dioxide gas registered by the applicant

The improvement of the connecting cable for welding, and more particularly, the welder body and the wire.

Connected between feeders or between the main wire feeder and the intermediate wire feeder

For the transmission of power supply, the supply of power and the transmission of control functions, and the construction of a welding connection cable for transporting welding gases. Particularly, control lines, gas pipes, and conductors are to be separated from the inner shell of the pipe. In the structure of Utility Model Registration No. 0208866, which independently forms a coating layer of rubber material so that the control line and the conductor in the shell have a double protective layer, the structure of the conductor is improved by the AL assembly line at the center. The conductor layer is formed and the conductor is formed by braiding the CU assembly line on the main surface of the AL conductor layer.

Utility Model Registration No. 0208866 CO2 gas welding connection cable registered by the present applicant has a double protective layer of the control line and the conductor in the outer shell to improve the durability by increasing the resistance to external impact, the conductor and control housed inside The short-circuit of the wire is fundamentally cut off to ensure safety, and it can be repaired only by cutting the corresponding part without cutting the whole cable when repairing the cable. It is becoming.

However, as the length of cable applied in the construction of large ships or large steel structures has increased recently, the weight of the cable has increased and many workers have to apply excessive force during the installation and movement of the cable. Bar which is emerging and pursues lightweighting in all parts constituting cable

In particular, weight reduction of the conductor, which accounts for more than 60% of the total weight, is the most necessary.

The present invention was devised to solve the above problems. The control line, the gas pipe, and the conductor are separately accommodated inside the outer shell of the tube, but the control line and the conductor are each formed in a completely separated state by forming a coating layer of rubber material. In the structure where the control line and the conductor in the outer shell have a double protective layer, the structure of the conductor is improved.In the center, the AL conductor layer is formed by an AL assembly line with a specific gravity of 2.7 and 3.3 times lighter than the CU with a specific gravity of 8.96. It is formed on the main surface of the AL conductor layer by braiding the CU assembly line excellent in electrical conductivity and tensile strength, which constitutes the conductor. This is a structure that significantly improves the weight without deteriorating the electrical conductivity. It is very easy to handle and the AL conductor layer is completely protected by the braided CU conductor layer. Since twos close contact even when the terminal operation of the conductor without the spacing between the developer and the conductor loss of the conductor and the workability is very easy and allows a current value is increased to be effective that the heat generation will not occur during prolonged periods of welding.

Referring to the configuration of the present invention in detail based on the accompanying drawings as follows.

1 is a perspective view showing the configuration of the present invention, Figure 2 shows a longitudinal cross-sectional view showing a cross-sectional state of the present invention to form a tubular outer shell (1) of rubber or soft PVC, or a corresponding material The control line 7, the gas pipe 2, and the conductor 3 are structured separately from the inside of the shell 1, but the control line 7 and the conductor 3 each independently form a coating layer of rubber material. So that the control line 7 and the conductor 3 in the shell have a double protective layer, but the conductor associates the AL assembly line in the center to form the AL conductor layer 5, and the AL conductor layer. On the main surface of (5), a CU assembly line is braided to form a CU conductor layer 6.

At this time, the AL conductor layer 5 has a structure in which the wire diameters are enlarged, aggregated, and assembled so as to obtain a value similar to the resistivity of the wire diameters of the conventional CU conductors. The AL conductor layer 5 and the CU conductor layer ( The formation ratio of 6) is added to each other to satisfy the allowable current value.

Fig. 3 shows a main portion perspective view showing the end treatment state of the inventive cable, in which the AL conductor 5 layer and the conductor layer 6 braided by CU form a coaxial structure and have a significantly lighter specific gravity of the AL conductor 5 therein. It is designed by weight and light weight, and by braiding the CU assembly line with excellent tensile strength and electrical conductivity to the outside. This completely absorbs the shock not only protects the AL conductor layer 5, but also has a strong and very good effect. In the terminal work of the conductor, the conventional cable as shown in FIG. Unlike in the prior art, in which heat generation occurs during welding for a long time while being unwound, the CU aggregate lines are formed in a braided layer structure, as shown in FIG. As it is not loosened, it is close to the conductor without any loss or separation between conductors, so it is very easy to work and the allowable current value is increased, so that the heating does not occur even when welding for a long time.

As described above, the present invention constitutes an AL conductor with a relatively high specific gravity inside, which facilitates the movement and installation of a cable by weight and light weight, thereby improving workability and safety, and having excellent tensile strength and electrical conductivity to the outside. It is a structure that increases the electrical conductivity of the cable and improves durability by composing the conductor layer. This structure is a structure in which the CU conductor layer completely absorbs external shock and protects the AL conductor layer. There is also a very good effect in the terminal processing.
