본 발명은 외부전류(전지등)에 의하여 작동되는 안전밸브용 전자석 및 그 제조방법에 관한 것이다.The present invention relates to an electromagnet for a safety valve operated by an external current (battery, etc.) and a manufacturing method thereof.
온도감지부가 가스(석유등) 연소기기의 불꽃에 접촉되도록 배치된 열전대(실화센서)의 전력에 의하여 흡인력을 발생시키거나, 전지등의 강제전류출력에 의하여 흡인력을 발생시키고, 이 흡인력에 의하여 안전밸브에 밸브체를 열림상태로 유지시키는 안전장치가 사용되고 있다.The temperature sensing unit generates a suction force by the power of a thermocouple (fire sensor) arranged to contact the flame of a gas (petroleum) combustion device, or generates a suction force by a forced current output of a battery, and is safe by this suction force. Safety devices are used to keep the valve body open in the valve.
이러한 용도로 사용되는 전자석은 저전압, 저전류로 충분한 흡인력을 발생시킬 수 있고, 또 안전밸브를 확실하게 작동시킬 수 있는 것이 중요하며, 또한 장착성을 향상시키기 위하여 콤팩트한 것이 바람직하다. 이것을 위해서는, U자형의 자성체 심(고정철심)을 이용함과 아울러, 특히 전지등에 의한 강제 흡인력을 높이기 위하여 이 고정철심에 가능한 여러 겹으로 가는 피복도선을 감아서 전자코일을 형성할 필요가 있다.The electromagnet used for this purpose is capable of generating sufficient suction force at low voltage and low current, and it is important to be able to operate the safety valve reliably, and it is preferable to be compact for improving the mountability. To this end, it is necessary to use a U-shaped magnetic core (fixed core) and, in order to increase the forced suction force by the battery or the like, in particular, to cover the plurality of layers of the cover wire as possible as possible to form the electromagnetic coil.
그런데 종래에는, 보빈에 피복도선을 감아 형성한 전자코일을 고정철심에 끼워 넣어서 전자석을 형성하고 있다. 따라서, 종래의 안전밸브용 전자석은 저전류에서의 흡인력이 충분하지 못하였고, 전자코일의 부피가 커지는 결점이 있었다.In the related art, an electromagnet is formed by sandwiching an electromagnetic coil formed by winding a coated conductor on a bobbin on a fixed iron core. Therefore, the conventional electromagnet for safety valve has a drawback that the suction force at low current is not enough, and the volume of the electromagnetic coil is large.

And the other end of which is connected to the outer lead wire, and an electromagnetic coil of a coated conductor wound directly on both arms of the magnetic core. And a.
본 발명에서는 대략 U자형의 자성체 심의 양 암부에 직접 절연피복선을 감았기 때문에, 매우 가는 피복도선을 권취수를 많게 하여 감을 수 있다. 이 결과, 전자석의 저전압, 저전류에서의 작동이 가능하게 되며, 또한 콤팩트하게형성할 수 있다.In the present invention, since the insulation coating wire is wound directly on both arm portions of the substantially U-shaped magnetic core, a very thin coated wire can be wound with a large number of windings. As a result, the electromagnet can be operated at low voltage and low current, and can be formed compactly.
특허청구범위 제2항의 제조방법에 의하면, 전자코일을 감는 작업 및 솔더링작업을 용이하게 할 수 있기 때문에, 생상성이 우수하다.According to the manufacturing method of claim 2, since the work of winding an electronic coil and the soldering work can be made easy, it is excellent in productivity.
특허청구범위 제3항의 제조방법에 의하면, 외측리드선의 용접, 브레이징, 솔더링등의 융착에 의한 융착부의 접합강도의 저하를 방지할 수 있으며, 융착부의 절손을 방지할 수 있다.According to the manufacturing method of claim 3, it is possible to prevent a decrease in the joining strength of the welded portion due to welding, brazing, soldering, etc. of the outer lead wire, and to prevent breakage of the welded portion.

이어서, 전자석(10)의 제조방법을 제3도 및 제4도에 의거하여 설명한다.Next, the manufacturing method of the electromagnet 10 is demonstrated based on FIG. 3 and FIG.
전자석(10)은, 제3도에 나타낸 바와같이 중심리드선(55) 및 외측리드선(17)을 가로로 구부려 둔다. 구부리는 각도는 피복도선을 감는 권취지그(jig)(9)의 작동에 방해가 되지 않는 각도라면 중심전극핀(5) 또는 전자석 홀더(1)의 중심축에 대하여 90도, 또는 90도 이하 혹은 90도 이상으로 하여도 된다. 이 상태에서 권부지그(9)를 작동시켜 피복도선(70)을 회동파이프(91)내를 통과시켜 공급하면서 외측리드선(17)에 감고, 이어서 회동파이프(91)를 이동기구(도시생략)로 변위시켜 자성체 심(6)의 일측 암부(63)에 감고, 다시 회동파이프(91)를 변위시켜 자성체 심(6)의 타측 암부(64)에 감고, 최후로 회동파이프(91)를 변위시켜 중심리드선(55)에 감는다.As shown in FIG. 3, the electromagnet 10 bends the center lead line 55 and the outer lead line 17 horizontally. The bending angle is 90 degrees or less than 90 degrees with respect to the central axis of the center electrode pin 5 or the electromagnet holder 1 if the angle does not interfere with the operation of the winding jig 9 winding the sheathed conductor. You may be 90 degree or more. In this state, the winding jig 9 is operated to wind the coated conductive wire 70 through the inside of the rotating pipe 91 and to supply it to the outer lead wire 17. Then, the rotating pipe 91 is moved to a moving mechanism (not shown). Displace the wound around the one arm portion 63 of the magnetic core 6, the rotation pipe 91 is again displaced to the other arm 64 of the magnetic core 6, and the rotation pipe 91 is finally displaced to the center It is wound around the lead wire 55.
또한, 선을 감을 때에는 전자석 홀더, 전자석측을 회전시켜도 된다.In addition, when winding a line, you may rotate an electromagnet holder and an electromagnet side.
이와같이 한 후, 외측리드선(17) 및 중심리드선(55)을 디핑등에 의하여 솔더링하여 전자코일(7)과 전기적으로 도통시킨다. 또한, 제4도에 나타낸 바와같이, 외측리드선(17) 및 중심리드선(55)을 구부려서 축방향으로 지향시킨다. 이 상태에서 코일하우징(21)의 하단부(23)를 전자석 홀더(1)의 머리부(16)에 외측에서 끼움으로써 제1도에 나타내는 안전밸브(100)가 조립된다.After this, the outer lead wire 17 and the center lead wire 55 are soldered by dipping or the like to electrically conduct with the electromagnetic coil 7. As shown in FIG. 4, the outer lead line 17 and the center lead line 55 are bent and directed in the axial direction. In this state, the safety valve 100 shown in FIG. 1 is assembled by fitting the lower end 23 of the coil housing 21 to the head 16 of the electromagnet holder 1 from the outside.
외측리드선(17)은 제3도에 나타낸 바와같이 단부에 만곡부(18)를 가지며, 이 만곡부(18)의 선단측(1a)이 전자석 홀더의 상단면(15)에 둘레방향으로 용접, 브레이징, 솔더링등에 의하여 융착되고, 제4도에 나타낸 바와같이 만곡부(18)에서 후단측(1b)이 축방향으로 구부려져 있다. 따라서 융착공정에서 편평하게 변형하거나 경화하여 물러진 선단측(1a)을 변형시키지 않고 후단측(1b)을 구부릴 수 있으므로, 안전밸브(100)의 신뢰성이 향상된다.The outer lead wire 17 has a curved portion 18 at its end, as shown in FIG. 3, and the tip side 1a of the curved portion 18 is welded, brazed, and circumferentially to the upper surface 15 of the electromagnet holder. It is fused by soldering etc., and as shown in FIG. 4, the rear end side 1b is bent in the axial direction by the curved part 18. As shown in FIG. Therefore, the rear end side 1b can be bent without deforming the front end side 1a deformed or cured flat in the welding process, thereby improving the reliability of the safety valve 100.
제5도 및 제6도는 외측리드선(17)의 융착구조에 대한 타실시예를 나타낸다. 이 실시예에서는, 제5도에 나타낸 바와같이 외측리드선(17)의 하단을 J자형으로 구부리고, 제6도에 나타낸 바와같이 전자석 홀더(1)의 상단면(15)을 산(山)형상의 테이퍼면으로 하고서 스폿용접한 것이다. 상단면(15)을 테이퍼면으로 함으로써 용접을 신속 또한 확실하게 할 수 있는 이점이 있다.5 and 6 show another embodiment of the fusion structure of the outer lead line (17). In this embodiment, as shown in FIG. 5, the lower end of the outer lead wire 17 is bent in a J shape, and as shown in FIG. 6, the upper end surface 15 of the electromagnet holder 1 is formed in a mountain shape. Spot-welded with tapered surface. By making the upper surface 15 a tapered surface, there is an advantage that welding can be quickly and surely performed.
제7도의 (a),(b),(c)는 피복도선(70)을 감고서 솔더링한 후의 외측리드선(17) 및 중심리드선(55)의 처리방법을 예시하고 있다. 어느것이나 외측리드선(17) 및 중심리드선(55)을 코일하우징(21)의 장착에 방해되지 않게 구부려져 있으며, 이것 이외의 처리방법을 채용하여도 된다.(A), (b), (c) of FIG. 7 illustrate a method of treating the outer lead wire 17 and the center lead wire 55 after winding and soldering the coated conductive wire 70. In either case, the outer lead wire 17 and the center lead wire 55 are bent so as not to interfere with the mounting of the coil housing 21, and a treatment method other than this may be adopted.
