Description

인버터 모듈{Inverter Module} Inverter Module

본 발명은 인버터 모듈에 관한 것으로, 특히 커넥터를 인버터 하우징에 일체로 형성함으로써 부품수량과 조립공정을 축소할 수 있는 인버터 모듈에 관한 것이다.The present invention relates to an inverter module, and more particularly, to an inverter module capable of reducing the quantity of parts and the assembly process by integrally forming a connector in the inverter housing.

일반적으로 엔진과 모터로 구동하는 하이브리드자동차와 모터만으로 구동하는 전기자동차는 모터를 구동하려면 높은 전압과 전류를 필요로 하게 된다. In general, hybrid vehicles driven by engines and motors and electric vehicles driven by motors require high voltages and currents to drive the motors.

그러므로, 하이브리드자동차나 전기자동차에는 고전압배터리와 저전압배터리를 구비하고, 배터리전압을 모터구동을 위한 전압과 전장품을 위한 12V 저전압으로 전환시켜주는 컨버터와 함께 배터리의 DC 전압을 3상 AC전압으로 변환하고 모터 회전수를 제어하기 위한 인버터가 필수적으로 구비되어진다.Therefore, hybrid or electric vehicles are equipped with a high voltage battery and a low voltage battery, and converts the DC voltage of the battery into a three-phase AC voltage with a converter that converts the battery voltage into a voltage for motor driving and a 12V low voltage for electrical equipment. An inverter for controlling the motor speed is essentially provided.

도 3은 종래에 따른 하이브리드 차량이 인버터와 함께 구성된 예를 나타낸다.3 shows an example in which a hybrid vehicle according to the related art is configured together with an inverter.

도시된 바와 같이, 하이브리드 차량은 모터(MG1)와 발전기(MG2) 및 엔진을 기본 구성으로하고, 고전압배터리와 저전압배터리로 이루어진 배터리(5)와, 배터리(5)와 전원케이블(6)로 연결되고 컨버터(4)와 함께 모듈화된 인버터(1)를 필수 구성으로 하게 된다.As shown, the hybrid vehicle has a motor MG1, a generator MG2, and an engine as a basic configuration, and is connected to a battery 5 consisting of a high voltage battery and a low voltage battery, a battery 5, and a power cable 6. And the inverter 1 modularized together with the converter 4 becomes an essential configuration.

상기 인버터(1)에는 전체형상을 이루는 하우징의 한쪽 측면부위로 돌출되어진 커넥터플랜지(3)에 커넥터(100)가 결합되는데, 이와 같이 커넥터(100)가 별도로 결합되는 인버터(1)의 구조는 커넥터 분리형 인버터로 불린다.The inverter 1 is coupled to the connector flange 3 protruding to one side portion of the housing constituting the overall shape, and thus the structure of the inverter 1 to which the connector 100 is separately coupled is a connector. It is called a separate inverter.

상기와 같이 구성된 커넥터(100)가 3상 AC 전압을 모터와 발전기로 연결하기 위해서는 각각 3개의 전선이 필요한 3상 인버터에 적용되면, 3상 인버터에는 각 3상을 연결할 수 있도록 3개의 버스바로 구성됨으로써 커넥터(100)의 단자도 동일하게 3개로 구성되어진다.When the connector 100 configured as described above is applied to a three-phase inverter that requires three wires in order to connect three-phase AC voltage to a motor and a generator, the three-phase inverter includes three bus bars to connect each three-phase. As a result, three terminals of the connector 100 are similarly configured.

DC 전압을 AC로 변환하여 모터와 발전기로 출력해주는 인버터의 특성으로 이에 구비된 커넥터(100)도 모터와 발전기로 각각 출력해주는 한쌍의 제1ㅇ2커넥터(200,300)로 구성되고, 상기 한쌍의 제1ㅇ2커넥터(200,300)는 인버터(1)의 커넥터플랜지(3)에 형성된 한쌍의 커넥터홀(3a,3b)로 각각 끼워져 볼트체결되어진다.The inverter 100 converts the DC voltage into AC and outputs it to the motor and the generator. The connector 100 also includes a pair of first and second connectors 200 and 300 that output to the motor and the generator, respectively. 1 and 2 connectors 200 and 300 are each bolted into a pair of connector holes 3a and 3b formed in the connector flange 3 of the inverter 1.

상기 한쌍의 제1ㅇ2커넥터(200,300)는 서로 공용화되면 그 크기를 줄일 수 있지만, 모터와 발전기가 각각 서로 다른 사양을 가져 서로 공용화가 될 수 없다.When the pair of first and second connectors 200 and 300 are shared with each other, the size can be reduced, but the motor and the generator have different specifications, and thus cannot be shared with each other.

도 4는 종래에 따른 인버터 모듈에서 필요한 커넥터 부품수량과 조립공정을 나타낸다.Figure 4 shows the connector parts quantity and assembly process required in the inverter module according to the prior art.

도 4(가)와 같이, 조립이 완료된 한쌍의 제1ㅇ2커넥터(200,300)는 인버터(1)의 커넥터플랜지(3)에 형성된 한쌍의 커넥터홀(3a,3b)로 각각 결합되어진 후, 인버터(1)의 내부에서 버스바(500)와 전기적으로 연결되어진다.As shown in FIG. 4 (a), the pair of first and second connectors 200 and 300, which are assembled, are coupled to the pair of connector holes 3a and 3b formed in the connector flange 3 of the inverter 1, respectively. It is electrically connected with the bus bar 500 in the inside of (1).

도 4(나)는 한쌍의 제1ㅇ2커넥터(200,300)와 전기적으로 연결되는 버스바(500)로서, 도시된 바와 같이 버스바(500)는 프레임을 이용해 일체화된 제1ㅇ2버스바(501,502)로 구성되고, 상기 제1ㅇ2버스바(501,502)에는 3상 인버터 특성으로 각각 3개의 버스바를 구비하게 된다.4 (b) is a bus bar 500 that is electrically connected to a pair of first and second connectors 200 and 300. As shown in FIG. 4, the bus bar 500 is a first bus bar integrated with a frame. 501 and 502, and the first and second bus bars 501 and 502 are provided with three bus bars, respectively, with three-phase inverter characteristics.

도 4(다)는 커넥터(100)와 버스바(500)가 인버터내부에서 전기적으로 연결된 조립상태로서, 도시된 바와 같이 인버터(1)의 커넥터플랜지(3)에 형성된 한쌍의 커넥터홀(3a,3b)에 각각 끼워진 제1ㅇ2커넥터(200,300)는 제1ㅇ2버스바(501,502)와 각각 연결되고 배터리(5)와 케이블(6)로 연결됨으로써 전기적 연결상태를 이루게 된다.4 (c) is an assembly state in which the connector 100 and the bus bar 500 are electrically connected to the inside of the inverter, and a pair of connector holes 3a, which are formed in the connector flange 3 of the inverter 1, as shown in FIG. The first and second connectors 200 and 300 respectively fitted to 3b) are connected to the first and second bus bars 501 and 502, respectively, and are connected to the battery 5 and the cable 6 to form an electrical connection state.

이러한 상태에서 도 3과 같이 모터와 발전기쪽으로 이어진 상대부품커넥터(400)를 제1ㅇ2커넥터(200,300)에 끼우게 되면, 배터리(5)와 인버터(1) 및 모터와 발전기가 서로 전기적으로 회로를 이루게 된다.In this state, when the mating component connector 400 extending toward the motor and the generator is inserted into the first and second connectors 200 and 300 as shown in FIG. 3, the battery 5, the inverter 1, and the motor and the generator are electrically connected to each other. Will be achieved.

하지만, 상기와 같이 인버터(1)의 외부에 장착되는 커넥터(100)는 커넥터플랜지(3)의 커넥터홀(3a,3b)에 끼워진 후 볼트체결되어야 하고 그 내부에서 별도 부품인 버스바(500)와 함께 연결되어야 함으로써, 커넥터(100)는 인버터(1)와 장착하기 위한 충분한 크기의 공간을 필요로 할 수밖에 없게 된다.However, as described above, the connector 100 mounted on the outside of the inverter 1 should be bolted after being inserted into the connector holes 3a and 3b of the connector flange 3 and the bus bar 500 which is a separate part therein. By being connected together with, the connector 100 is forced to require a space of sufficient size for mounting with the inverter (1).

통상, 커넥터(100)는 구성부품으로 인해 한정된 크기를 가져 축소할 수 있는 공간이 거의 없고, 이러한 커넥터(100)의 크기 축소 불가는 결국 인버터(1)의 크기 증가를 가져오는 한 원인으로 작용하게 된다.In general, the connector 100 has a limited size due to the component, there is little space to be reduced, and this impossibility of reducing the size of the connector 100 eventually serves to cause an increase in the size of the inverter 1. do.

또한, 커넥터(100)는 그 구성부품으로 인한 취약함도 갖는데, 일례로 도 3의 제1커넥터(200)와 같이 하우징(201)으로 결합되어진 헤더(202)와, 기밀을 위한 씨일(203)과, 고정을 위한 너트(204) 및 전기적 연결을 위해 버스바와 연결되는 단자(205)로 구성됨으로써 많은 부품조립공정에 따른 비용상승을 가져올 수 밖에 없다.In addition, the connector 100 also has a weakness due to its components. For example, the header 202 coupled to the housing 201, such as the first connector 200 of FIG. 3, and the seal 203 for airtightness. And, by the nut 204 for fixing and the terminal 205 connected to the bus bar for the electrical connection is bound to bring a cost increase due to many parts assembly process.

상기와 같은 커넥터(100)의 비용상승은 결국 인버터(1)의 비용상승을 가져오는 다른 원인으로 작용하게 된다.The increase in the cost of the connector 100 as described above will act as another cause of the cost increase of the inverter (1).

이에 더해, 커넥터(100)는 인버터(1)와의 씰링면과 고정을 위한 볼트조립과 탭(Tap) 가공 공정과 더불어 인버터(1)의 내부에서 커넥터(100)와 전기적 인터페이스를 위해 버스바(500)가 필수적으로 갖추어져야 함으로써, 전체적으로 인버터(1)의 조립공정 증가와 비용상승을 가져오는 또 다른 원인으로 작용하게 된다.
In addition, the connector 100 includes a busbar 500 for electrical interface with the connector 100 inside the inverter 1, together with a bolting and tapping process for sealing and securing the sealing surface with the inverter 1. ) Must be equipped as an essential factor, which acts as another cause of increasing the assembly process of the inverter 1 and raising the cost as a whole.
