자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리{Electric coil assembly for automotive water pump clutch}Electric coil assembly for automotive water pump clutch

본 발명은 자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리에 관한 것으로서, 좀 더 상세하게 워터펌프 클러치에서 전자석 역할을 하는 이엠씨코일(EMC Coil; Electric Magnet Clutch Coil)과 커넥터 사이에 박스가 구성되어 다이오드와 저항을 보관하고 상호 용이하게 연결할 수 있도록 구성된 일렉트릭 코일 어셈블리에 관한 것이다.The present invention relates to an electric coil assembly for a water pump clutch of an automobile, and more particularly, a box is formed between an electric coil and a connector which act as an electromagnet in a water pump clutch. It relates to an electric coil assembly configured to store and interconnect easily.

주지하는 바와 같이 자동차의 워터펌프 클러치는 엔진의 시동에 의해서 가열된 엔진을 냉각시키는 냉각수를 순환시킬 때 모터의 동력을 워터펌프에 전달하거나 차단하는 작용을 한다.As is well known, the water pump clutch of a vehicle functions to transmit or block the power of the motor to the water pump when circulating the coolant that cools the engine heated by the start of the engine.

좀 더 구체적으로는 워터펌프 클러치에 장착된 일렉트릭 코일에 전원을 인가하여 전자석이 되도록 하면 인근한 클러치판이 전자석의 자력으로 밀착되면서 동력이 전달되고 전원을 차단하면 원래의 위치로 복귀하여 동력이 차단되는 것으로서, 자동차뿐만 아니라 산업기계 등 많은 분야에서 유용하게 사용되고 있다.More specifically, when the electric coil is applied to the electric coil mounted on the water pump clutch to become an electromagnet, power is transmitted while the adjacent clutch plate is in close contact with the magnetic force of the electromagnet. As a vehicle, it is usefully used in many fields such as automobiles as well as industrial machinery.

종래 자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리의 구성을 살펴보면, 코일 하우징 내부에 저항과 다이오드가 내장되어 코일선과 연결되는 구성으로 되어 있다.Looking at the configuration of the electric coil assembly for a water pump clutch of a conventional vehicle, a resistor and a diode is built in the coil housing and connected to the coil wire.

상기와 같이 코일 하우징 내부에 저항과 다이오드가 안착되어 코일선과 연결되는 경우에는 공간을 확보하고 에폭시와 같은 충진물을 채우는데 많은 어려움이 있어 작업성이 떨어지는 관계로 생산원가가 비싸게 형성되는 원인을 제공하는 단점이 있다.As described above, when a resistor and a diode are seated inside the coil housing and connected to the coil wire, there is a lot of difficulty in securing a space and filling a filler such as epoxy, which provides a cause of high production cost due to poor workability. There are disadvantages.

그리고, 코일선과 저항과 다이오드를 상호 연결할 때 코일선이 가느다란 하기 때문에 확실하게 연결하지 못하는 사례가 빈번하여 불량이 많이 발생되고, 또 취급시 전선이 다른 부분에 걸려 당겨지면서 단락이나 누전이 발생하는 단점이 있다.In addition, when the coil wire, the resistance and the diode are interconnected, the coil wire is thin, so the case of failing to reliably connect frequently occurs, and a lot of defects occur, and a short circuit or a short circuit occurs when the wire is caught by another part during handling. There are disadvantages.

또한, 코일로부터 연결되는 코일선은 코일 하우징에 구멍을 형성하여 외부로 돌출시킨 후 전선의 끝에 전원을 공급받기 위한 커넥터를 설치하는 구조로 되어 있기 때문에 커넥터가 코일 하우징에 견고한 상태로 연결되지 못하는 등 구조적으로 많은 문제점이 있다.In addition, since the coil wire connected from the coil has a structure in which a hole is formed in the coil housing to protrude to the outside and a connector is installed to receive power at the end of the wire, the connector cannot be firmly connected to the coil housing. There are many problems in structure.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 일렉트릭 코일 어셈블리를 제조할 때 다이오드 및 저항을 보관할 수 있는 박스를 제공하여 커넥터와 함께 상호 조립되는 구성의 일렉트릭 코일 어셈블리를 제공토록 하며,The present invention is to solve the above problems, to provide an electric coil assembly of a configuration that is assembled with the connector by providing a box for storing a diode and a resistor when manufacturing the electric coil assembly,

또한, 코일선과 다이오드 및 저항과 커넥터를 신속, 간편하고 확실하게 연결하여 누전을 방지할 수 있는 박스와 커넥터의 구조를 제공하여 품질을 향상시킬 수 있는 자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리를 제공할 수 있도록 하는데 소기의 목적이 있다.In addition, by providing a structure of a box and a connector that can prevent a short circuit by connecting the coil wire, the diode, the resistor, and the connector quickly, easily and reliably, an electric coil assembly for a water pump clutch of an automobile can be improved. The purpose is to make it possible.

상기 목적을 달성하기 위한 본 발명에 의한 자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리는, 코일선이 권회되어 전자석 역할을 하는 이엠씨코일과 코일 하우징 사이에 장입되고 단자 안착부가 형성된 절연커버와, 박스 안착부가 단자 프레임이 구비된 커넥터와, 다이오드와 저항을 보관할 수 있는 박스로 구성된 것이 본 발명에 특징이다.The electric coil assembly for a water pump clutch of a vehicle according to the present invention for achieving the above object is, an insulation cover is inserted between the coil coil and the coil housing to act as an electromagnet and the terminal seating portion, the box seating portion It is a feature of the present invention that the connector is provided with a terminal frame, and a box for storing a diode and a resistor.

본 발명에 의한 자동차의 워터펌프 클러치용 일렉트릭 코일 어셈블리에 의하면, 코일선과 연결된 다이오드와 저항을 박스에 넣고 전기적으로 연결하였기 때문에 일관성이 있는 조립과 확실한 연결에 의해서 누전을 방지할 수 있는 효과가 있으며,According to the electric coil assembly for a water pump clutch of an automobile according to the present invention, since a diode and a resistor connected to a coil wire are put in a box and electrically connected, an electric leakage can be prevented by a consistent assembly and a reliable connection.

또한, 다이오드와 저항이 보관된 박스를 코일 하우징의 외부로 고정설치하는 동시에 단자 프레임이 구비된 커넥터와 함께 연결하였기 때문에 구조적으로 안전하고 간결하여 품질이 크게 향상된 구조를 갖는 일렉트릭 코일 어셈블리를 제공하는 효과가 있다.In addition, since the box in which the diode and the resistor are stored is fixed to the outside of the coil housing and connected with the connector having the terminal frame, it is an effect of providing an electric coil assembly having a structure that is structurally safe and concise and greatly improved in quality. There is.
