Description

트랜스의 누설자의 협지구{LEAKAGE CORE HOLDER OF TRANSFORMER}Narrow strip of trans leaker {LEAKAGE CORE HOLDER OF TRANSFORMER}

본 고안은 트랜스의 누설자의 협지구에 관한것이다.The present invention relates to the narrow region of the leaker of the transformer.

일반적인 트랜스는 하나의 보빈에 1차 코일과 2차 코일을 상하로 적층되게 권선하여 구성되어 있으나 트랜스의 외경이 커서 전광판이나 네온싸인등과 같은 한정된 공간에 수용하기 어렵기 때문에 트랜스의 1차코일과 1차 코일을 각각의 보빈에 권선한 다음 두 보빈을 길이방향으로 결합하여 트랜스의 외경을 보다 작게 형성한 것을 사용한다.The general transformer is composed of winding the primary coil and the secondary coil in a single bobbin stacked up and down, but because the outer diameter of the transformer is large, it is difficult to accommodate in a limited space such as an electric signboard or neon sign. The primary coil is wound around each bobbin, and then two bobbins are joined in the longitudinal direction to form a smaller outer diameter of the transformer.

이러한 트랜스에서는 1차 코일보빈과 2차 코일보빈을 결합할 때 서로 접속된 E형 코어의 접속단부의 중간부는 공간이 형성되기 때문에 누설자를 삽입해야 한다. 그러나 종래에는 코어의 단부측에 누설자를 접착제로 접착 한 다음 코어를 결합하였으나 접착제가 건조되기까지 시간이 지연되고 트랜스의 조립과정에서 접착된 누설자가 부디치면 탈락되는 등 능률적으로 트랜스를 조립하기 어려운 문제점이 있았다.In such a transformer, when the primary coil bobbin and the secondary coil bobbin are combined, an intermediate part of the connection end portion of the E-type core connected to each other has a space, so a leaker must be inserted. However, in the related art, it is difficult to efficiently assemble the transformer such that the leaker is adhered to the end of the core with an adhesive and then the core is bonded, but the time is delayed until the adhesive is dried and the leaked leaker is dropped during the assembly of the transformer. There was.

본 고안은 이러한 종래의 문제점을 시정하기 위하여,트랜스의 1차코일 보빈과 2차코일 보빈의 양단부측에 각각 코어를 협지하는 협지편과을 형성하고 2차 코일 보빈의 내단부에는누설자를 협지하는 협지편을 형성하며 1차 코일 보빈의 내단부에는 결합편을 형성하여 1차코일이 감긴 보빈과 2차코일이 감긴 보빈을 서로 결합하기 전에 누설자를 협지편 사이에 협지한 다음 결합편에 의하여 두 보빈을 물리적으로 결합하고 결합된 두 보빈의 외측에서 E형 코어를 각각 협지편에 협지되게 보빈에 결합시키어 트랜스를 조립할 수 있게 구성하였다.In order to correct this problem, the present invention forms a gripping piece for sandwiching the cores on both ends of the primary coil bobbin and the secondary coil bobbin of the transformer, and the gripping gripping the leaker on the inner end of the secondary coil bobbin. Form a piece, and form an engaging piece at the inner end of the primary coil bobbin to sandwich the leaker between the sandwich pieces before joining the bobbin wound with the primary coil and the bobbin wound with the secondary coil to each other, and then the two bobbins by the coupling piece. And physically coupled to the bobbin on the outside of the combined two bobbins respectively coupled to the bobbin so as to sandwich the pinch pieces were configured to assemble the trans.

본 고안의 트랜스는 보빈에 형성된 협지편에 의하여 두 보빈의 결합부 사이의 공간에 누설자를 간편하게 협지할 수 있고 또 결합편에 의해서 두 보빈을 결합할 수 있으며, 또 협지편에 의하여 두 코어를 협지할 수 있게 구성하였기 때문에 트랜스의 조립이 간편하고 신속하여, 종래 두 보빈 사이에 누설자를 접착하여 조립하던 것에 비하여 보다 능률적으로 트랜스를 조립 제조할 수 있게 안출한 것이다.The transformer of the present invention can easily sandwich the leaker in the space between the coupling portions of the two bobbins by the sandwich pieces formed on the bobbin, and can combine the two bobbins by the coupling pieces, and sandwich the two cores by the sandwich pieces. Since it is configured to be able to assemble the transformer is simple and fast, compared to the conventional assembly of the leaker between the two bobbins, the transformer can be assembled and manufactured more efficiently.

트랜스(T)의 1차코일 보빈(1)과 2차 코일 보빈(2)에 각각 1차코일(C1)과 2차코일(C2)을 감은 다음 서로 결합하여 각 보빈에 E형 코어(3)(3a)를 결합하고 두 보빈(1)(2)의 결합부의 공간부(a)에 누설자(4)를 설치하게 된 것에 있어서. 두 보빈(1)(2)의 외단부측에는 각각 코어(3)(3a)를 협지하는 협지편(1a)(2a)을 중간에 간격(R)을 두고 각각 대향되게 코어의 두께 폭으로 형성하고 보빈(2)의 내단부에는 누설자(4)를 협지하는 협지편(2b)을 중간에 간격을 두고 누설자(4)의 길이와 같은 폭으로 형성하며, 보빈(1)의 내단부에는 상기 누설자의 협지편(2b)과 결합되는 결합편(1b)을 각각 대응되게 형성하여 보빈끼리 결합할 수 있게 구성된 것이다.The primary coil (C1) and the secondary coil (C2) are wound on the primary coil bobbin (1) and the secondary coil bobbin (2) of the transformer (T), respectively, and then bonded to each other to form an E-type core (3) on each bobbin. (3a) in which the leaker (4) is provided in the space (a) of the engaging portion of the two bobbins (1) and (2). On the outer end side of the two bobbins (1) and (2), gripping pieces (1a) and (2a) sandwiching the cores (3) and (3a), respectively, are formed in the thickness width of the core so as to face each other with an interval R in the middle. The inner end of the bobbin 2 is formed with a sandwich piece 2b for holding the leaker 4 in the same width as the length of the leaker 4 with an interval therebetween. The coupling pieces 1b coupled to the gripping pieces 2b of the leaker are formed to correspond to each other so that the bobbins can be coupled to each other.

이와 같이 된 본 고안은 1차코일(C1)이 감긴 1차코일 보빈(1)과 2차코일(C2)이 감긴 2차코일 보빈(2)을 결합하기 직전에 보빈(2)의 내단부에 형성된 협지편(2b) 사이에 각각 누설자(4)를 가로로 협지시키고 1차코일 보빈(1)의 내단부에 형성된 결합편(1b)을 상기 누설자의 협지편(2b) 외측으로 결합시키어 두 보빈(1)(2)의 접합된 공간부(a)에 누설자(4)가 고정되게 한다. 이어서 각 보빈(1)(2)에 E형 코어(3)(3a)를 협지편(1a)(2a)에 협지되게 끼워 결합시키어 트랜스(T)를 조립한다.The present invention as described above has a primary coil bobbin (1) wound around the primary coil bobbin (1) and the secondary coil bobbin (2) wound around the second coil (C2) immediately before joining the inner end of the bobbin (2) Between the formed gripping pieces 2b, the leaker 4 is horizontally sandwiched, respectively, and the coupling pieces 1b formed at the inner end of the primary coil bobbin 1 are coupled to the outside of the gripping pieces 2b of the leaker. The leaker 4 is fixed to the joined space a of the bobbin 1 and 2. Subsequently, the E T cores 3 and 3a are sandwiched between the bobbins 1 and 2 so as to be sandwiched by the sandwich pieces 1a and 2a to assemble the transformer T.

조립된 트랜스(T)의 1차코일 보빈(1)과 2차코일 보빈(2)에 결합된 각 코어(3)(3a)의 내단부는 서로 접속되며 내부코어(i)와 외부코어(u) 사이의 공간부(a)에는 누설자(4)가 고정되어 트랜스의 자기누설을 방지한다.The inner ends of the respective cores 3 and 3a coupled to the primary coil bobbin 1 and the secondary coil bobbin 2 of the assembled transformer T are connected to each other and have an inner core i and an outer core u. The leaker 4 is fixed to the space portion a between them to prevent magnetic leakage of the transformer.

또 협지편(2b)에 의하여 누설자(4)가 안전하게 협지되기 때문에 별도의 접착제로 접착하지 않아도 코어의 조립시에 누설자가 탈락되는 일이 없다.In addition, since the leaker 4 is securely clamped by the gripping piece 2b, the leaker does not fall off during assembly of the core without adhering with a separate adhesive.

또 코어는 각각의 협지편에 협지되므로 결합성이 양호하고 또 협지편의 중간에 간격이 형성되어 그 틈으로 코어를 잡은 손가락을 밀어넣어 코어를 용이하게 결합할 수 있다. 일단 두 보빈을 결합고 코어를 결합하면 두 코어의 내부코어와 외부코어 사이의 공간에 위치됨으로 외부로 누설자가 탈락될 우려가 없으며 보다 신속하게 트랜스의 조립이 가능하다.In addition, since the core is sandwiched between the respective sandwich pieces, the bondability is good, and a gap is formed in the middle of the sandwich piece so that the core can be easily engaged by pushing a finger holding the core into the gap. Once the two bobbins are combined and the cores are joined, they are located in the space between the inner and outer cores of the two cores, so that there is no risk of leaking out to the outside, and the trans assembly can be performed more quickly.

본 고안은 트랜스의 1차 코일 보빈과 2차 코일 보빈의 양단부측에 협지편을 각각 형성하여 협지편에 의하여 코어를 협지할수 있게 구성하였기 때문에 간편하게 코어를 조립할 수 있다.According to the present invention, since the sandwich pieces are formed on both ends of the primary coil bobbin and the secondary coil bobbin of the transformer, the cores can be clamped by the sandwich pieces, so that the core can be easily assembled.

또 2차코일 보빈의 내단부에 누설자의 협지편을 형성하였기 때문에 누설자를 접착하지 않고 신속 간편하게 협지편에 협지할 수 있다.In addition, since the gripping piece of the leaker is formed at the inner end of the secondary coil bobbin, the gripping piece can be quickly and easily clamped without adhering the leaker.

1차코일 보빈과 2차코일 보빈을 결합편에 의하여 결합할 수 있기 때문에 간편하게 두 보빈을 결합할 수 있으며, 보빈의 결합시에 누설자가 탈락될 우려가 없기 때문에 작업성이 양호하다.Since the primary coil bobbin and the secondary coil bobbin can be combined by a joining piece, the two bobbins can be easily combined, and workability is good because there is no fear that the leaker will drop off when the bobbin is joined.

또 코어가 결합된 후에는 누설자의 상하측에 코어가 받치게 됨으로 누설자가 외부로 탈락될 우려가 없으며 보다 능률적으로 고품질의 트랜스를 다량 조립제작할 수 있는 등의 여러가지 효과가 있다.In addition, since the core is supported on the upper and lower sides of the leaker after the core is joined, there is no fear that the leaker may fall out, and there are various effects such as to manufacture a large amount of high-quality transformer more efficiently.
