The leakage current such as an electric field or electromagnetic wave generated from the electromagnetic shielding portion is formed to be attenuated by a separate resistance element formed on one side of the substrate, so that the leakage current harmful to the human body is formed so as not to be detected during the voltage test. The present invention relates to a leakage current detection prevention device of an electromagnetic shielding portion.

일반적으로 온도조절기용 전자파 차폐회로는 전기매트와 같은 전기제품의 컨트롤러(제어장치) 내에 형성되어 제품 사용시 발생되는 전기장 및 전자파(유해파) 등을 접지포인트로 전위시킨 후 이를 감쇠 또는 소멸시키도록 형성된다.In general, the electromagnetic shielding circuit for thermostats is formed in a controller (control device) of an electrical product such as an electric mat, and is formed to attenuate or dissipate an electric field and electromagnetic wave (harmful wave) generated during the use of the product to a ground point. .

이때, 상기 전자파 차폐회로의 구성은 도 3에 도시된 바와 같이, 몸체가 도체로 이루어진 볼륨노브(1)는 몸체 내부에는 공간부가 형성되어 별도의 도통선(3:도체)이 끼움 결합되고, 상기 결합된 도통선(3)은 하부로 연장되어 별도의 볼륨샤시(2:도체)와 맞닿아 전기적인 통전상태를 유지하도록 형성된다.At this time, the configuration of the electromagnetic shielding circuit, as shown in Figure 3, the volume knob 1 of the body is made of a conductor, a space portion is formed inside the body is fitted with a separate conductive line (conductor) 3: The combined conductive line 3 extends downward to be in contact with a separate volume chassis (conductor) to maintain an electrically energized state.

While diffractive, the volume shaft 220 of the insulator is provided at one side of the upper end of the upwardly protruding body in which a catching groove 221 corresponding to the shaft fastening groove 130 of the volume knob is installed.

이때, 상기 볼륨샤시(200)는 볼륨노브(100)와 절연블럭(300)에 의해 절연거리를 확보하며 서로 이격되도록 형성된다.In this case, the volume chassis 200 is formed to ensure an insulating distance by the volume knob 100 and the insulating block 300 to be spaced apart from each other.

이때, 볼륨샤시(200)의 체크핀(230)은 접지포인트를 취사선택하며 설정하도록 형성되는 것으로, 예컨데 체크핀 1번은 전기장 접지포인트/ 체크핀 2번은 볼륨 포인트/ 체크핀 3번은 전자파 접지포인트 등으로 설정하여 내전압 검사에 따른 누설전류의 검출방지는 물론 제품출하 후 일반적인 사용시 사용자가 선택요구에 맞춰 유해파를 단속하도록 형성된다.At this time, the check pin 230 of the volume chassis 200 is formed to select and set the ground point, for example, check pin 1 is the electric field ground point / check pin 2 volume point / check pin 3 is the electromagnetic ground point, etc. It is set to prevent leakage current detection according to the withstand voltage test and to control the harmful waves in accordance with the user's selection requirements during normal use after shipment.

또한, 상기 전도판(210)은 다수개의 체크핀(230)을 갖는 도체로써, 후술되는 저항소자(500) 및 확인램프(600)와 통전되도록 형성된다.In addition, the conductive plate 210 is a conductor having a plurality of check pins 230, and is formed to be energized with the resistance element 500 and the confirmation lamp 600 which will be described later.

이때, 상기 전도판(210)의 내측에는 볼륨샤프트(220)와 연동되는 별도의 전열판이 부설되어 볼륨노브(100)를 설정포인트(접지포인트)에 회절시키면 동시에 볼륨샤프트(220)가 연동되고, 이에 볼륨샤프트(220)의 하단 전열판이 회절하면서 다수개의 체크핀(230) 중 사용요구에 따른 검사포인트로 통전이 이루어지도록 형성된다.At this time, a separate heat transfer plate which is interlocked with the volume shaft 220 is disposed inside the conductive plate 210 to diffract the volume knob 100 to a set point (ground point), and the volume shaft 220 is simultaneously linked. Accordingly, the lower heat transfer plate of the volume shaft 220 is diffracted and is formed to conduct electricity to the inspection points according to the use requirements of the plurality of check pins 230.

이때, 상기 볼륨샤프트(220) 부도체로써, 전도판(210)을 기준으로 상향 돌출되되, 돌출된 상단부에는 볼륨노브(100)의 돌기와 대응되는 걸림홈 부설되어 상술한 연동 회절이 가능하도록 형성된다. At this time, the volume shaft 220 as a non-conductor, protrudes upward with respect to the conducting plate 210, the protruding upper end is provided with a locking groove corresponding to the projection of the volume knob 100 is formed to enable the above-mentioned interlocking diffraction.

한편, 상기 절연블럭(300)은 몸체의 내측 중앙에 관통공(340)이 형성되어 볼륨샤프트(220)에 끼워지도록 마련된다.On the other hand, the insulating block 300 is provided so that the through hole 340 is formed in the inner center of the body is fitted to the volume shaft 220.

이러한 절연블럭(300)은 상부측 볼륨노브(100)와 하부측 볼륨샤시(200)를 서로 이격시키며 내전압 검사에 따른 검사기로 측정시 전기장 또는 전자파 등의 유해파가 검출되지 않도록 절연거리를 확보하여 안전검사의 통과를 제공하게 된다. 이에 상기 절연블럭(300)은 설정된 높이값이 10mm~20mm 이며, 내경에서 외경까지의 두께가 5mm~10mm인 것이 바람직하다. 이는 볼륨노브 측에 소통되는 내전압을 가장 효과적으로 차폐시킬 수 있음은 물론 제작크기도 최적이기 때문이다.The insulating block 300 spaces the upper volume knob 100 and the lower volume chassis 200 from each other and secures an insulating distance so that harmful waves such as electric fields or electromagnetic waves are not detected when measured by an inspector according to the withstand voltage test. It will provide a passing test. Accordingly, the insulating block 300 has a set height value of 10 mm to 20 mm, and a thickness from an inner diameter to an outer diameter is 5 mm to 10 mm. This is because the withstand voltage communicated to the volume knob side can be most effectively shielded, and the manufacturing size is also optimal.

이때, 상기 절연블럭(300)은 몸체 중앙에 관통공(340)이 형성되어 볼륨샤프트(220)에 끼워진 후 볼륨노브(100)와 볼륨샤시(200)의 절연 매개체 역할을 하도록 형성된다.In this case, the insulating block 300 is formed so that the through-hole 340 is formed in the center of the body and inserted into the volume shaft 220 to serve as an insulating medium of the volume knob 100 and the volume chassis 200.

한편, 상기 도통선(400)은 몸체가 선재로 이루어진 도체로써, 상기 몸체의 상단부는 볼륨노브의 도통선가이드(120)에 감싸지며 끼워지도록 형성되고, 하단부는 볼륨샤시(200)의 상부면과 맞닿는 한편, 상기 상부면에서 일측으로 분기된 단부(410)는 기판 일측에 고정되도록 형성된다.On the other hand, the conductive wire 400 is a conductor made of a wire rod, the upper end of the body is formed so as to be wrapped around the conductive wire guide 120 of the volume knob, the lower end and the upper surface of the volume chassis 200 While abutting, the end portion 410 branched to one side from the upper surface is formed to be fixed to one side of the substrate.

이때, 상기 도통선(400)의 몸체 중 코일 형상으로 말린 부분은 상술한 볼륨노브의 도통선가이드(120)와 절연블럭(300) 상단면 사이에 끼움되어 고정되는 것으로, 도체로 된 볼륨노브(100)와 기판 상의 저항소자(500)가 서로 통전상태를 이루도록 형성된다.At this time, the coiled portion of the body of the conductive wire 400 is sandwiched between the conductive wire guide 120 and the upper surface of the insulating block 300 of the above-described volume knob is fixed, the volume knob made of a conductor ( 100 and the resistance element 500 on the substrate are formed to be in an energized state with each other.

즉, 전기적으로 연결된 볼륨노브(100)와 도통선(400)은 저항소자(500)를 거쳐 확인램프(600) 일측 연결선과 연결되고, 이에 볼륨샤시(200)는 볼륨노브(100)에 대해 절연블럭(300)으로 하여금 이격되면서 확인램프(600)의 타측 연결선과 연결되는 바, 이는 내전압 검사에 따른 통전시 절연저항 및 절연거리를 확보하여 누설전류의 검출을 방지하도록 구성된다.That is, the volume knob 100 and the conductive line 400 electrically connected to each other are connected to one side of the confirmation lamp 600 via the resistor element 500, and the volume chassis 200 is insulated from the volume knob 100. Bar 300 is spaced apart and connected to the other connection line of the confirmation lamp 600, which is configured to ensure the insulation resistance and the insulation distance during the energization according to the withstand voltage test to prevent the detection of leakage current.

한편, 상기 저항소자(500)는 도통선(400) 중 기판에 고정된 단부(410)와 전기적 통전을 이루도록 형성되는 한편, 타측은 확인램프(600) 및 볼륨샤시(200)와 통전되도록 형성된다.On the other hand, the resistance element 500 is formed so as to be in electrical communication with the end portion 410 of the conductive wire 400 is fixed to the substrate, while the other side is formed to be energized with the confirmation lamp 600 and the volume chassis 200. .

즉, 상기 저항소자(500)는 내전압 검사시 전기장, 전자파 등의 누설전류가 검출되지 않도록 설정된 저항값을 가지며, 상기 설정 저항값은 기준 저항값에 비해 높게 형성되도록 이루어진다.That is, the resistance element 500 has a resistance value set so that leakage currents such as an electric field and electromagnetic waves are not detected when the withstand voltage test is performed, and the set resistance value is formed to be higher than the reference resistance value.

예컨데, 기준 저항값이 8M일 경우 상기 설정 저항소자의 저항값은 15M로 형성되어 내전압의 안전성을 확보하도록 형성된다.For example, when the reference resistance value is 8M, the resistance value of the set resistance element is formed to 15M to ensure the safety of the withstand voltage.

다시말해, 고전압의 전류를 흘려 테스트하는 내전압 검사에서 본원 온도조절기용 전자파 차폐기는 누설전류의 검출을 미연에 방지하도록 차폐 회로기판 일측에 별도의 저항소자(500)를 부설하여 상기한 내전압 검사시 안전성을 승인받을 수 있도록 형성된다.In other words, the electromagnetic shield for the thermostat of the thermostat of the present application is installed in a separate resistance element 500 on one side of the shielded circuit board to prevent the detection of leakage current. It is formed so that it can be approved.

이와 같이, 본 발명은 제품출하 전 시행되는 온도조절기의 내전압 시험시 전자파 차폐부로 하여금 인가된 고전압을 설정시간 동안 견디도록 형성됨은 물론 상기 전자파 차폐부에서 발생되는 전기장 또는 전자파 등의 누설전류가 기판 일측에 형성된 별도의 저항소자에 의해 감쇄되도록 형성함으로써 인체에 유해한 상기 누설전류가 내전압 검사시 검출되지 않도록 하는 효과가 있다.As described above, the present invention is formed to withstand the high voltage applied to the electromagnetic shielding part during the withstand voltage test of the temperature controller to be carried out before shipment for a set time, as well as the leakage current of the electric field or electromagnetic wave generated from the electromagnetic shielding part on one side of the substrate. It is formed to be attenuated by a separate resistance element formed in the there is an effect that the leakage current harmful to the human body is not detected during the withstand voltage test.
