The present invention is a solenoid valve for simultaneously supplying gas and power to a torch of a welding machine.

The solenoid valve 1 includes an upper housing 10 having a cylindrical shape with an inner space formed therein and a lower side opened and an upper side formed with an injection hole 11 into which gas is injected, And a casing (20) inserted in the hollow portion of the coil winding body (20) so as to protrude at the lower end thereof and open in the lower direction, wherein the coil winding body A rod 32 which is inserted into the hollow portion of the casing 31 and one end of which protrudes out of the casing 31 and which is mounted between the inner surface of the rod 32 and the casing 31; And an outlet hole 51 through which the gas flows to the outside is formed on the lower side.

The outlet hole (51) is constituted by a lower housing (50) closed by a rod (32).

In the coil-wound body 20 of the hollow shape, a passage 21 penetrating in the longitudinal direction is formed on the thickness surface formed by the inner periphery and the outer periphery, and when the coil is energized, S is moved upward to move upwardly so that the outflow hole 51 is opened and the gas introduced into the passage 21 is discharged to the outside through the outflow hole 51. [

An injection hole is formed in an upper surface of the lower housing for injecting gas from an external gas passage. A power line is connected to one side of the lower housing to supply power to the solenoid valve.

The coil winding body is inserted into a lower opening of the lower housing, and the coil winding body is formed as a hollow cylindrical shape. The upper surface and the lower surface of the coil winding body protrude more than the outer circumference of the coil winding body And is formed so as to have an outer circumferential extension.

A coil is wound on the outer periphery of the coil winding body and a valve portion 30 is mounted on the hollow portion of the coil winding body.

A rod 32 which is inserted into a hollow portion of the casing 31 and one end of which protrudes to the outside of the casing 31; And a spring (S) is mounted between the inner surface of the casing (31).

The upper surface of the casing is in a state in which the load return magnetic body 33 is engaged.

The rod and the rod return magnetic body are made of a magnetic material, and the casing is made of a non-magnetic material. When electricity is supplied to the valve portion, the rod return magnetic body and the rod come into contact with each other.

Accordingly, when electricity is applied to the coil, the rod 32 moves upward while pressing the spring S, and when the electricity is cut off to the coil, the rod is moved downward by the elastic force of the spring.

The casing serves to guide the linear movement of the rod.

An iron plate having a hollow hole is mounted between the upper surface of the coil take-up body and the surface where the upper housing contacts with each other, so that the magnetic force of the load return magnetic body is increased by contacting the load return magnetic body,

An O-ring is provided between the coil winding body and a surface facing the steel plate, and an O-ring is also provided between surfaces of the steel plate and the upper housing facing each other to prevent gas from leaking.

In the coil winding body 20, a passage 21 penetrating in the longitudinal direction is formed on the thickness surface formed by the inner periphery and the outer periphery. The gas injected into the upper housing passes through the passages of the coil winding body 20, .

The rubber is coupled to a lower surface of the rod, and the rubber is coupled to a lower surface of the upper housing and serves to block the outflow hole of the lower housing from flowing out the torch gas of the welder.

Therefore, the rubber coupled to the lower surface of the rod functions to cut off the gas that flows into the upper housing and outflows to the lower housing, and also blocks electricity from the upper housing to the lower housing.

In addition, the upper housing 10 and the lower housing 50 are made of a conductor that is electrically conductive.

The conductor can be divided into an electric conductor and a heat conductor. The electric conductor is a material with good electrical conductivity. The solenoid valve installed between the welding machine and the torch is made of a conductor and is electrically conductive.

The outer surfaces of the upper housing 10 and the lower housing 50 are covered with an insulator.

The insulator is a material that does not conduct electricity or heat. It is also called nonconductor. Indeed, the electrical conductivity and thermal conductivity are very small. Glass, ebonite, diamond, rubber, etc. are electrically non-conductive, while cotton, asbestos, ashes and the like are thermally non-conductive.

These materials are called insulators because they are also used to prevent heat or electricity from escaping. The handles of electrical appliances, such as sockets and plugs, are made of insulators to be safe to handle.

Therefore, the solenoid valve is covered with an insulator so that it can be safely used by a user.

Further, the solenoid valve for simultaneously supplying the gas and the power source of the present invention is connected to a one-touch connector for a cable for supplying gas and power, and supplies gas and power to the torch of the welding machine.

As shown in FIGS. 8 and 9, the one-touch connector for a cable includes a socket 100 for supplying gas and power, and a plug 200 connected to the socket to supply gas and power .

Accordingly, the valve device of the socket is separated from the plug, and the valve body is forwardly directed by the urging spring urged between the protrusion of the valve body 131 and the gas supply pipe, so that the front part of the protrusion in the valve body The gasket is inserted into the small diameter portion and the front surface of the protrusion is brought into close contact with the engaging jaw formed due to the difference in the inner diameters of the large diameter portion and the small diameter portion,

At this time, by forming the O-ring 150 on the entire surface of the projection, the sealing force can be further increased.

14, when the socket and the plug are coupled, the gas inlet pipe 222a of the plug head 220 is inserted into the small diameter shaft SH of the socket head 120 to compress the compression spring 134 And the gas in the socket head 120 is guided to the gas inlet pipe 222a of the plug through the through hole 133 by allowing the through hole 133 of the valve body 131 to be positioned within the large diameter BH of the socket head 120 ).

It is preferable that the gas inlet pipe of the plug is formed so as to protrude further to the front surface of the plug head and the outside diameter is formed to coincide with the inside diameter of the small diameter.

Also, an O-ring 150 is formed on the front surface of the socket head to reinforce the buffering force and the sealing force.

The gas supply pipe and the gas flow pipe are continuously formed on the outer periphery of the gas supply pipe so as to prevent the gas from easily flowing out during compression in order to fasten the gas cable.

The O-rings are denoted by the same reference numeral 150.

Meanwhile, the socket head can be divided into a power supply part 121 of a hollow body to be fastened to the inside of the socket grip cap and a gas supply part 122 of a hollow body to be fastened inside the power supply part 121.

The power receiving unit 221 is also provided with a power receiving terminal 221a for receiving power corresponding to the power supplying terminal 121a of the socket head 120. [

As a result, when the socket and the plug are fastened, the power supply terminal 121a on the socket side and the power supply reception terminal 221a on the plug side are connected to each other and inserted into the power supply terminal 121a and the power reception terminal 221a And the power connection jack (not shown) are coupled to each other.

Since the method of supplying power to the power connection jack is a common configuration, a detailed description thereof will be omitted.

15 is a schematic view showing a state in which an insertion hole of a socket and a coupling protrusion of a plug are fastened in a one-touch connector for a cable.

A plurality of coupling protrusions 112 are formed on the inner circumferential surface of the socket grip cap 110. The coupling protrusions 112 of the socket grip cap 110 are linearly formed on the outer circumferential surface of the plug head 220 And a fixed end portion 227 formed to extend in the circumferential direction at an end of the entry portion 226. The fixed end portion 227 is formed to extend in the circumferential direction.
