Description

엘피지 차량의 베이퍼라이저 커넥터{VAPORIZER CONNECTOR OF LPG TYPE VEHICLE}VAPORIZER CONNECTOR OF LPG TYPE VEHICLE}

본 발명은 엘피지 차량에 관한 것으로서, 특히 엘피지 차량의 베이퍼라이저 커넥터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an Elpige vehicle, and more particularly to a vaporizer connector of an Elpige vehicle.

통상적으로, 엘피지 차량의 베이퍼라이저(Vaporizer)의 기기측 커넥터(110) (Connector)에는 도 1에 도시된 바와 같이 6개의 핀이 구비된다.Typically, six pins are provided in the device-side connector 110 of the vaporizer of the LPG vehicle, as shown in FIG. 1.

각각의 핀 가운데 1, 2, 3번 핀은 전원 공급용 핀이며, 4, 5, 6번 핀은 해당되는 솔레노이드 밸브(120, 130, 140) 구동을 제어하는 핀이다.Pins 1, 2, and 3 of each pin are power supply pins, and pins 4, 5, and 6 are pins for controlling driving of the corresponding solenoid valves 120, 130, and 140.

예를 들어, 4번 핀은 슬로우 컷 솔레노이드 밸브(120)(Slow Cut Solenoid Valve)의 제어핀이며, 5번 핀은 2차 로크 솔레노이드 밸브(130)(2nd Lock Solenoid Valve)의 제어핀이다.For example, pin 4 is a control pin of the slow cut solenoid valve 120 (Slow Cut Solenoid Valve), pin 5 is a control pin of the secondary lock solenoid valve 130 (2nd Lock Solenoid Valve).

6번 핀은 컷 오프 솔레노이드 밸브(140)(Cut Off Solenoid Valve)의 제어핀이다.Pin 6 is a control pin of the cut off solenoid valve 140 (Cut Off Solenoid Valve).

한편, 제어사양이 비교적 적은 엘피지 차량의 경우 각각의 솔레노이드 밸브(120~140)를 제어하기 위한 방식으로, 도 2에 도시된 바와 같이 트랜지스터 구동방식을 이용한 분리 제어방식을 적용하였으나, 이러한 트랜지스터 구동방식은 전류 제한 요소가 강한 회로로 구성되어 있다.On the other hand, in the case of an LPI vehicle having a relatively small control specification, a separate control method using a transistor driving method is applied as a method for controlling the respective solenoid valves 120 to 140, as shown in FIG. 2. The circuit consists of a strong current limiting element.

위와 같은 방법을 사용할 때 종래에는 비효율적인 전원 공급용 핀 수로 인해 시스템적인 낭비 및 원가상승의 요인을 발생시키는 문제점이 있었다.When using the above method, there has been a problem of causing a systemic waste and a cost increase due to the inefficient number of pins for power supply.

본 발명의 목적은 엘피지 차량의 베이퍼라이저 커넥터 핀 수를 감소하여 시스템을 단순화시킴으로써 원가절감 및 안정성을 도모할 수 있는 엘피지 차량의 베이퍼라이저 커넥터를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a vaporizer connector of an Elpgi vehicle, which can reduce cost and stability by reducing the number of pins of the vaporizer connector pin of an Elpi vehicle.
