차량용 압축기의 필드코어Field Cores for Automotive Compressors

본 고안은 차량 공조장치의 냉동싸이클용 압축기에 관한 것으로, 특히 압축기의 동력을 단속하는 전자클러치에 자력을 발생시키는 차량용 압축기의 필드코어에 관한 것이다.The present invention relates to a compressor for a refrigeration cycle of a vehicle air conditioner, and more particularly, to a field core of a vehicle compressor for generating a magnetic force in the electromagnetic clutch to control the power of the compressor.

차량용 공조장치의 냉동싸이클 압축기에 따른 전자클러치는 도 1과 같다. 부호 1은 구동측 풀리로, 도시하지 않은 밸트를 개재하여 차량 엔진에서 회전력을 받아 회전하게 된다. 부호 2는 단면이 ㄷ자 형상의 2중 원통형상으로 형성된 구동측 로터로, 풀리(1)와는 용접등의 접합수단으로 일체로 접합되어 있다. 이 로터(2)의 내주부에는 베어링(3)이 배설되고, 이 베어링(3)에 의해 로터(2)는 도시하지 않은 압축기의 프론트 하우징의 원통 돌출부상에 회전자재하게 지지되어 있다. 여기서, 압축기는 자동차용 공조장치의 냉동싸이클 냉매압축용이다.The electromagnetic clutch of the refrigeration cycle compressor of the vehicle air conditioner is shown in FIG. 1. Reference numeral 1 is a driving side pulley, and rotates by receiving a rotational force from the vehicle engine via a belt (not shown). Reference numeral 2 is a drive-side rotor formed in a double cylindrical shape having a U-shape in cross section, and the pulley 1 is integrally joined by a joining means such as welding. A bearing 3 is disposed in the inner circumferential portion of the rotor 2, and the rotor 3 is rotatably supported on the cylindrical projection of the front housing of the compressor (not shown) by the bearing 3. Here, the compressor is for refrigeration cycle refrigerant compression of the vehicle air conditioner.

4는 고정자극부재로서 역할하는 코일하우징으로, 단면이 ㄷ자 형상의 2중 원통형상으로 금속으로 형성되어 있다. 이 코일하우징(4)의 내부에는 전자코일(6)이 삽입되어 수지부재(7)에 의해 절연고정되어 있으며, 이는 상기 로터(2)의 단면 ㄷ자형상의 내부공간내에 미세하게 배설되어 있다.4 is a coil housing which serves as a fixed magnetic pole member, and a cross section is formed of a metal in a double cylindrical shape having a c-shape. Inside the coil housing 4, the electromagnetic coil 6 is inserted and insulated and fixed by the resin member 7, which is finely disposed in the cross-section c-shaped inner space of the rotor 2.

8은 로터(2)의 마찰면에 대향하여 배설된 아마추어이고, 링형상으로 금속으로 형성되어 있다. 이 아마추어(8)는 전자코일(6)의 비통전시에 탄성부재의 탄성력에 의해 로터(2)의 마찰면에서 소정의 미소거리로 이격된 위치에 보지하도록 되어 있다.8 is an armature arrange | positioned facing the friction surface of the rotor 2, and is formed in metal in ring shape. The armature 8 is held at a position spaced apart from the friction surface of the rotor 2 by a predetermined minute distance by the elastic force of the elastic member when the electromagnetic coil 6 is not energized.

여기서 상기 전자코일은 도 2와 같이 코일하우징(4)에 면테이프가 권면된 전자코일(6)이 삽입되고 그 외면을 수지부재(7)로 에폭시 처리하게 된다.In this case, as shown in FIG. 2, the coil coil 4 is inserted into the coil coil 4 with the coil coil 4 wound thereon, and the outer surface thereof is epoxy-treated with the resin member 7.

이의 제조과정은 지그에 코일을 와인딩(11)한 후 절연 및 코일의 무너짐 등을 방지하기 위해 1차 테이핑(Taping)을 실시(12)하고 지그로부터 와인딩된 코일을 탈거(13)하여 다시 면테이프로 2차 테이핑을 실행(14)한 후 코일하우징에 수납(15)하며, 이후 절연을 위해 수지부재에 의해 에폭시처리(16)하는 작업공정을 거쳐 필드코어가 완성된다.The manufacturing process of the coil after winding (11) to the jig to perform the first taping (12) to prevent insulation and the collapse of the coil (12), and remove the coil (13) wound from the jig to the cotton tape again After the secondary taping (14) to the furnace 15 is received in the coil housing, and then the field core is completed through the operation process of the epoxy treatment 16 by the resin member for insulation.

그러나 이러한 필드코어 제조방법에 의하면 코일뭉치에 테이핑하는 과정에서 작업시간이 오래 걸릴 뿐만 아니라 수작업에 의해 테이핑하여야 하기 때문에 작업성이 곤란하였다.However, according to the field core manufacturing method, the workability is not only long because the work time is long in the process of taping the coil bundle, but also the taping is performed manually.

또한 전자코일의 리드선을 코일하우징 외측으로 인출하는데 있어서 그 인출공간을 확보하는데 어려움이 있었다.In addition, in drawing out the lead wire of the electronic coil to the outside of the coil housing, it was difficult to secure the drawing space.

본 고안은 이러한 점을 감안하여 안출된 것으로, 특히 필드코어의 제조공정을 간단하게 함과 동시에 전자코일의 리드선 인출이 용이토록 하는 차량용 압축기의 필드코어를 제공하는데 목적이 있다.The present invention has been made in view of this point, and an object of the present invention is to provide a field core of a vehicle compressor that simplifies the manufacturing process of the field core and at the same time facilitates lead wire extraction of the electromagnetic coil.

이러한 목적을 달성하기 위한 본 고안의 차량용 압축기의 필드코어는 비자성체로 형성되고 중앙에 중공부를 갖는 릴형상의 코일보빈과, 상기 코일보빈의 외주면에 권선되는 전자코일과, 자성체로 형성되고 상기 전자코일이 권선된 코일보빈을 수납하여 고정하는 코일하우징을 포함하는 것을 특징으로 한다.The field core of the vehicular compressor of the present invention for achieving the above object is formed of a non-magnetic material and has a reel-shaped coil bobbin having a hollow portion in the center, an electromagnetic coil wound around an outer circumferential surface of the coil bobbin, and formed of a magnetic material. It characterized in that it comprises a coil housing for receiving and fixing the coil wound bobbin coil.

그리고, 상기 코일보빈은 배면에 중공부 내주면측으로 리드선을 인출하기 위한 단턱을 형성되어 이곳으로 리드선을 인출하도록 한다.In addition, the coil bobbin is formed with a stepped portion for drawing the lead wire toward the inner circumferential surface side of the hollow portion to allow the lead wire to be drawn out there.

이러한 구성에 의하면, 전자코일의 리드선의 인출이 용이하고 릴형상의 코일보빈에 전자코일을 권하므로 권선 완료후 전자코일의 풀림을 방지할 수 있다.According to such a configuration, the lead wire of the electronic coil is easily drawn out and the coil is recommended to the reel-shaped coil bobbin to prevent the coil from being unwound after the winding is completed.

The insulation is fixed by the resin member 24. The resin member 24 is molded by injecting a resin material which can be molded at a relatively low temperature by epoxy resin or unsaturated polyester into the inner space of the coil housing 21.

또한 코일하우징(21)은 로터(2;도1 참조)의 단면 ㄷ자형상의 내부공간내에 미세하게 배설되어 있다.Further, the coil housing 21 is finely disposed in the cross-sectional c-shaped inner space of the rotor 2 (see Fig. 1).

그리고 상기 코일보빈(22)은 단면이 H자 형상의 릴형상으로 플라스틱 재질로 형성되어 있다. 이 코일보빈(22)의 배면에는 중공부 내주벽(22a)에서 외주벽측을 향해 둘레방향으로 단턱(22b)이 형성되며 그 공간으로 전자코일(23)의 리드선(23a)을 인출한다.The coil bobbin 22 is formed of a plastic material in the shape of a H-shaped reel. On the back of the coil bobbin 22, a stepped portion 22b is formed in the circumferential direction from the hollow inner circumferential wall 22a toward the outer circumferential wall side, and leads the lead wire 23a of the electromagnetic coil 23 into the space.
