본 발명은 고압트랜스포머의 고압선 절연구조에 관한 것으로, 더욱 상세하게 는 고압선과 코일의 연결부위를 압착방식으로 연결하되, 이러한 균일한 길이를 갖는 압착부위를 합성수지재 절연기구를 통해 수용하여 고압선과 코일의 연결부위를 코일로부터 절연시키도록 한 것이다.The present invention relates to a high-voltage wire insulation structure of a high-voltage transformer, and more particularly, to connect the connection portion of the high-voltage cable and the coil by a crimping method, and to receive the crimped portion having a uniform length through the synthetic resin insulation mechanism, the high-voltage cable and the coil The connection part of is to insulate from coil.

주지하다시피, 고압 트랜스포머는 전자레인지의 마그네트론과 같이 고압을 필요로 하는 기기에 적용되어 고압을 발생시키는 장치로서, E형 코어에 1차 코일과 이보다는 권선비가 큰 2차 코일을 각각 설치하고, E형 코어의 하부에는 I형 코어를 고정하며, I형 코어의 하부에는 타기기에 장착하기 위한 브라켓을 용접하여 고정하게 되는데, 1차 코일에는 전원 입력단자를 형성하여 교류전원을 인가하도록 하고, 2차 코일의 단부에는 부하와 연결되는 고압선을 연결하여 1차 코일과 2차 코일 사이의 상호유도작용에 의해 발생된 고전압을 부하에 전달할 수 있게 되어 있다.As is well known, high voltage transformer is a device that generates high pressure by applying to high voltage equipment such as magnetron of microwave oven, and installs primary coil and secondary coil with larger winding ratio in E type core, The lower part of the E-type core is fixed to the I-type core, and the lower part of the I-type core is fixed by welding a bracket for mounting on other equipment.The primary coil is formed with a power input terminal to apply AC power. At the end of the secondary coil, a high voltage line connected to the load is connected to transfer the high voltage generated by the mutual induction between the primary coil and the secondary coil to the load.

즉, 전원 입력단자를 통해 교류가 공급되어 1차 코일로 흐르게 되면 E형 코어와 I형 코어에 자계가 형성되고, 이 자계로 인해 1차 코일과 2차 코일에서는 상호유도작용이 발생되어 상대적으로 1차 코일에 비해 권선비가 큰 2차 코일에서 고전압이 발생되며, 이 고전압이 그 단부에 연결된 고압선을 거쳐 부하로 전달되는 것이다.That is, when AC is supplied through the power input terminal and flows to the primary coil, a magnetic field is formed in the E-type core and the I-type core, and due to the magnetic field, mutual induction occurs in the primary coil and the secondary coil. The high voltage is generated in the secondary coil, which has a larger winding ratio than the primary coil, and the high voltage is transmitted to the load through a high voltage line connected at its end.

이때, 2차 코일의 일측 단부는 고압선에 연결되어 출력측을 이루고, 그 반대쪽 단부는 E형 코어에 접지된 접지단자에 연결되어 접지측을 이루게 되는데, 도 1과 같이 출력측에서는 2차 코일(1) 일측 단부의 피복(절연을 위해 통상 에나멜로 피복됨)(1a)을 벗겨낸 후 고압선(2)에 권회하여 연결하고, 그 연결부위에 납땜을 하여 고정하게 되며, 이러한 2차 코일(1)과 고압선(2)의 납땜부위(3)를 절연지(4) 를 통해 감싸 2차 코일(1)의 일측에 고정하는 것이다.At this time, one end of the secondary coil is connected to the high-voltage line to form an output side, the other end is connected to the ground terminal grounded to the E-type core to form a ground side, as shown in Figure 1 the secondary coil (1) Peel off one side of the sheath (usually enameled for insulation) 1a, then wound and connected to the high-voltage cable 2, and soldered to the connection to fix it. The soldering portion 3 of the high-voltage cable 2 is wrapped with insulating paper 4 to be fixed to one side of the secondary coil 1.

따라서, 2차 코일(1)에 고압선(2)을 연결할 때 2차 코일(1)의 피복을 벗겨내는 공정, 고압선(2)의 피복을 벗겨내는 공정, 고압선(2)에 2차 코일(1)을 권회하는 공정, 납땜을 하는 공정 등이 필수적으로 요구되어 작업공수가 많아지고 복잡함은 물론 많은 시간이 소요되어 작업성 및 생산성이 떨어지며, 인건비의 증가 및 설비의 증가로 인해 제조원가가 상승하게 되는 문제가 있었고, 절연지(4)를 사용할 경우 쉽게 파손될 수 있고, 절연지(4)의 두께에 따라 절연성이 달라지므로 절연의 신뢰성이 떨어지게 되었으며, 외관이 깔끔하지 못한 단점도 있었다.Therefore, when connecting the high voltage line 2 to the secondary coil 1, the process of peeling off the cover of the secondary coil 1, the process of peeling off the cover of the high voltage line 2, the secondary coil 1 to the high voltage line 2 ) Winding process, soldering process, etc. are required to increase the labor cost and complexity, it takes a lot of time, workability and productivity decreases, manufacturing cost increases due to the increase of labor cost and equipment There was a problem, it can be easily broken when using the insulating paper 4, because the insulation properties vary depending on the thickness of the insulating paper 4, the reliability of the insulation is lowered, there was also a disadvantage that the appearance is not neat.

이를 감안하여 본 출원인은 특허출원 제 2004-62332 호(도 2참조)에서 2차 코일(10)과 고압선(20)의 사이에 연결단자(30)를 구비하되, 연결단자(30)를 상부가 개방된 반원형으로 구성하고 그 양측을 안쪽으로 각각 압착하여 고압선(20)의 단부와 피복이 제거되지 않은 상태의 2차 코일(10)의 단부를 연결단자(30)를 통해 각각 홀딩하며, 연결단자(30)의 홀딩부위 양측 내부에는 돌기(31)를 그 길이방향의 직각방향으로 다수개 나란히 형성하여 연결단자(30)의 압착시 2차 코일(10)의 피복이 상기 돌기(31)에 의해 절개되는 것에 의해 연결단자(30)를 매개로 2차 코일(10)과 고압선(20)이 통전되도록 구성함으로써 연결단자(30)의 압착시 돌기(31)가 2차 코일(10)의 피복을 절개하여 2차 코일(10)과 고압선(20)이 통전될 수 있고, 각 돌기(31)의 방향이 길이방향에 대해 직각을 이루므로 그 연결력을 더욱 강하게 구현할 수 있으며, 이와 같이 한번의 공정을 통해 강한 연결력과 통전성을 동시에 구현할 수 있게 되므로 작업성 및 생산성을 향상시킬 수 있고, 제조시간의 단축 및 제조원 가의 절감이 가능해지도록 한 고압 트랜스포머의 단자연결구조 및 그 방법을 개시한 바 있다.In view of this, the present applicant has a connection terminal 30 between the secondary coil 10 and the high voltage line 20 in Patent Application No. 2004-62332 (see FIG. 2), but the upper end of the connection terminal 30 is provided. Consists of an open semi-circular shape, each of which is pressed inward to hold the end of the high-voltage cable 20 and the end of the secondary coil 10 in a state where the covering is not removed, respectively through the connection terminal 30, the connection terminal A plurality of protrusions 31 are formed in both sides of the holding part 30 in the right angle direction in the longitudinal direction so that the covering of the secondary coil 10 is pressed by the protrusions 31 when the connecting terminal 30 is crimped. By cutting so that the secondary coil 10 and the high voltage cable 20 are energized through the connecting terminal 30, the projection 31 when the connecting terminal 30 is crimped to cover the secondary coil 10. The secondary coil 10 and the high voltage line 20 may be energized by cutting, and the direction of each projection 31 is perpendicular to the longitudinal direction. The connection force can be realized more strongly. In this way, the strong connection force and the energization can be realized at the same time, thereby improving workability and productivity, and reducing the manufacturing time and manufacturing cost. The terminal connection structure and method of the high voltage transformer have been disclosed.

그러나, 상기와 같이 2차 코일과 고압선을 연결단자를 통해 압착·연결하여 작업성 및 생산성을 향상시키고, 제조시간을 단축하며, 제조원가를 절감하더라도 이러한 2차 코일과 고압선의 연결부위를 종래와 마찬가지로 절연지를 통해 감싼 후 2차 코일의 일측에 고정하게 되면 절연지의 특성상 쉽게 파손되고, 절연지의 두께에 따라 절연성이 달라지므로 신뢰성이 떨어지며, 외관이 깔끔하지 못한 단점은 여전히 가지고 있는 것이라 할 수 있다.However, even if the secondary coil and the high-voltage cable is crimped and connected through the connection terminal as described above, even if the connection between the secondary coil and the high-voltage cable is reduced as in the past, the productivity and productivity are reduced, and the manufacturing cost is reduced. After wrapping through insulating paper and fixing it to one side of the secondary coil, it is easily broken due to the characteristics of the insulating paper, and the insulation property varies depending on the thickness of the insulating paper, so that the reliability is low and the appearance is not neat.

본 발명은 이러한 점을 감안하여 제안된 것으로, 2차 코일과 고압선을 연결단자를 통해 압착·연결하되, 이러한 연결부위를 합성수지재 절연기구에 수용한 상태로 2차 코일이 일측에 부착함으로써 2차 코일과 고압선의 연결부위가 유동되지 않아 원활한 절연이 가능해 짐은 물론 이 부위의 내구성을 향상시켜 신뢰성을 확보할 수 있으며, 외관을 깔끔하게 할 수 있는 고압 트랜스포머의 고압선 절연구조를 제공하고자 하는 것이다.The present invention has been proposed in view of this point, and the secondary coil and the high-voltage cable are crimped and connected through a connection terminal, but the secondary coil is attached to one side while the connection part is accommodated in a synthetic resin insulating mechanism. The connection between the coil and the high-voltage cable does not flow, which enables smooth insulation, as well as improving the durability of this area to ensure reliability, and to provide a high-voltage transformer insulation structure of a high-voltage transformer that can clean the appearance.

이하, 본 발명을 제시되는 실시예와 첨부된 도면에 따라 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 절연기구의 사시도이고, 도 4는 본 발명에 따른 절연기구를 사용한 고압 트랜스포머의 고압선 절연구조 설명도이다.3 is a perspective view of an insulator according to the present invention, and FIG. 4 is a diagram illustrating a high voltage line insulation structure of a high voltage transformer using the insulator according to the present invention.

본 발명에 따른 고압 트랜스포머의 고압선 절연구조는 도 3에 도시한 바와 같이 고압 트랜스포머의 2차 코일(10)과 고압선(20)의 사이를 연결단자(30)로써 압착·연결하여 이 연결단자(30)를 매개로 2차 코일(10)과 고압선(20)이 통전되도록 한 것에 있어서, 합성수지재로 되며, 중앙부에 가로방향으로 타부위보다 얇은 두께로 절첩선(101)이 형성되고, 이 절첩선(101)을 중심으로 배치되는 양측 덮개(110)(120)에는 연결단자(30)가 끼워지도록 가로 방향으로 단자끼움홈(111)(121)이 각각 형성되며, 각 단자끼움홈(111)(121)의 양측에는 연결단자(30)의 상하단부가 긴밀하게 끼워지도록 연결단자(30)의 길이와 동일한 간격으로 이탈방지돌기(112)(122)가 각각 형성되고, 일측 덮개(110)의 단자끼움홈(111) 상부에는 다수의 고정돌기(113)가 형성되며, 타측 덮개(120)의 동일위치에는 고정돌기(113)에 대응되는 고정홈(123)이 형성된 절연기구(100)를 구비하여 2차 코일(10)과 고압선(20)을 연결하는 연결단자(30)를 그 내측의 단자끼움홈(111)(121)에 수용한 상태로 2차 코일(10)의 측면에 부착하여서 된 것이다. 도면상에는 고정돌기(113)와 고정홈(123)이 2개씩인 것을 예로 하여 도시하였다.As shown in FIG. 3, the high voltage line insulation structure of the high voltage transformer according to the present invention is crimped and connected between the secondary coil 10 and the high voltage line 20 of the high voltage transformer with the connection terminal 30 to connect the connection terminal 30. The secondary coil 10 and the high-voltage cable 20 are energized by a medium). The secondary coil 10 and the high-voltage cable 20 are made of a synthetic resin material, and a fold line 101 is formed to have a thickness thinner than that of the other portions in the horizontal direction at the center portion. Terminal cover grooves 111 and 121 are formed in both sides of the cover 110 and 120, which are arranged around the 101, in the horizontal direction so that the connection terminals 30 are fitted therein, respectively, and each terminal fitting groove 111 ( On both sides of the 121, the separation prevention protrusions 112 and 122 are formed at intervals equal to the length of the connection terminal 30 so that the upper and lower ends of the connection terminal 30 are tightly fitted, and the terminal fitting of the one side cover 110 is formed. A plurality of fixing protrusions 113 are formed at the upper portion of the groove 111, and at the same position of the other cover 120. It is provided with an insulating mechanism 100 having a fixing groove 123 corresponding to the corner projection 113, the connecting terminal 30 for connecting the secondary coil 10 and the high-voltage wire 20, the terminal fitting groove (inside) 111 and 121 are attached to the side of the secondary coil 10 in a state accommodated. In the drawings, the fixing protrusion 113 and the fixing groove 123 are shown as an example.

이때, 이탈방지돌기(112)(122)는 그 상단부가 각 덮개(110)(120)의 안쪽면보다는 수평상 낮은 위치가 되도록 형성하여 양측 덮개(110)(120)가 닫히면 대응되는 이탈방지돌기(112)(122)의 사이로 구멍이 형성되도록 함으로써 이 부위로 2차 코일(10) 또는 고압선(20)이 통과되도록 한 것이다.At this time, the departure prevention protrusions 112 and 122 are formed so that their upper ends are horizontally lower than the inner surfaces of the respective covers 110 and 120 so that both side covers 110 and 120 are closed, thereby preventing the corresponding departure prevention protrusions. A hole is formed between the 112 and 122 so that the secondary coil 10 or the high voltage line 20 passes through this portion.

이와 같이 구성된 상태에서는 2차 코일(10)과 고압선(20)을 압착·연결하는 연결단자(30)가 이탈방지돌기(112)(122)의 사이에서 단자끼움홈(111)(121)에 긴밀하게 끼워지게 되고, 이와 연결된 2차 코일(10)과 고압선(20)은 각 덮개(110)(120) 가 덮이면서 이탈방지돌기(112)(122)의 사이로 형성되는 구멍을 통해 각각 빠져나올 수 있으며, 각 덮개(110)(120)가 덮이면 일측 덮개(110)에 형성된 고정돌기(113)가 타측 덮개(120)의 대응되는 고정홈(123)에 끼워맞춤 고정되는 것이므로 연결단자(30)가 절연기구(100)의 내측에 수용된 상태에서 어떠한 유동도 없이 그 위치를 유지할 수 있는 것이다.In this configuration, the connecting terminal 30 for crimping and connecting the secondary coil 10 and the high voltage cable 20 is in close contact with the terminal fitting grooves 111 and 121 between the separation preventing protrusions 112 and 122. The secondary coil 10 and the high voltage line 20 connected thereto may be escaped through holes formed between the separation preventing protrusions 112 and 122 while each cover 110 and 120 are covered. In addition, when each cover 110, 120 is covered, the fixing protrusion 113 formed on one side cover 110 is fitted to the corresponding fixing groove 123 of the other side cover 120 so that the connection terminal 30 Is able to maintain its position without any flow in the state accommodated inside the insulation mechanism (100).

즉, 전기적으로 절연되지 않은 부위인 연결단자(30), 이와 근접한 2차 코일(10) 및 고압선(20) 부위가 모두 절연기구(100)에 감싸인 상태로 유동없이 유지될 수 있는 것이며, 합성수지재로 된 절연기구(100)의 특성상 절연의 특성이 매우 뛰어나고, 절연지와는 달리 내구성을 가지고 있어 외력에 의해 파손될 가능성이 거의 없는 것이다.That is, the connection terminal 30, which is not electrically insulated, the secondary coil 10 and the high voltage line 20 adjacent thereto may be maintained without flow in a state surrounded by the insulation device 100, and the synthetic resin Due to the characteristics of the insulating device 100 made of ash, the insulating properties are very excellent, and unlike the insulating paper, it has durability, so that there is little possibility of being damaged by external force.

또한, 이러한 상태에서 절연기구(100)가 2차 코일(10)의 일측에 고정 테잎(T) 등의 수단에 의해 부착되어 고압 트랜스포머와 일체화되면 외력이 발생되더라도 절연기구(100)의 위치가 아무런 유동없이 제위치를 유지할 수 있음은 물론 깔끔한 마감이 가능하여 외관이 깔끔해지는 것이다.In addition, in such a state, when the insulation mechanism 100 is attached to one side of the secondary coil 10 by means of a fixing tape T or the like and integrated with the high voltage transformer, the position of the insulation mechanism 100 may be reduced even if an external force is generated. Not only can it stay in place without flow, but it can also be neatly finished to give it a clean appearance.

이상에서 설명한 바와 같이, 본 발명은 합성수지재로 된 절연기구를 통해 2차 코일과 고압선을 연결하는 연결단자를 유동없이 수용한 상태로 2차 코일의 일측에 부착·고정한 것이므로 합성수지재 절연기구의 특성상 탁월한 절연특성을 나타낼 수 있고, 내구성이 강해 외력에 의해 파손될 가능성이 없으며, 외관이 깔끔해지는 등 매우 유용한 효과가 있는 것이다.As described above, the present invention is attached to and fixed to one side of the secondary coil in a state in which the connecting terminal connecting the secondary coil and the high-voltage cable without flow through the insulating mechanism made of synthetic resin material, so in view of the characteristics of the synthetic resin insulation mechanism It can exhibit excellent insulation properties, durability is strong, there is no possibility of being damaged by external forces, and the appearance is very useful, such as a neat appearance.
