Another object of the present invention is to provide a component connection failure check circuit of the vehicle that can ensure the safety by switching to the check loop in the emergency when the component connection failure occurs during driving to ensure the normal operation.

이와 같은 본 발명의 목적은 달성하기 위한 수단으로는, 중요부품을 연결시키기 위한 중요 부품 커넥터에 쇼팅바(Shorting Bar)를 설치하고, 그 커넥터의 쇼팅바를 경유하여 각종 신호류 부품(예; 혼 (HORN), 방향지시등 (TURN SIGNAL LAMP)등)연결되게 배선하고 그 커넥터를 이용하여 중요 부품과 신호류 부품을 연결할 수 있게하여 중요부품 커넥터의 연결이 잘못되면 신호류 부품이 동작되지 않도록 함으로 달성되는 것이다.As a means for achieving the object of the present invention, a shorting bar is provided in the critical part connector for connecting the critical parts, and various signaling components (eg, horns) are provided via the shorting bar of the connector. HORN), TURN SIGNAL LAMP, etc.), and it is possible to connect important parts and signal parts by using the connector. will be.

이와같은 본 발명에 의하면, 중요 부품의 커넥터가 정확히 연결되지 못하면, 신호류 부품이 정상동작 되지 못하므로, 연결불량을 간단히 확인할수 있게 되는 것이다. 쇼팅바는 메일커넥터와 휘메일커넥터가 완전히 결합되면 정해진 두단자를 분리시키고 상기 양 커넥터가 완전히 결합되지 않으면 정해진 두 단자를 접속 시키는 것이 있으며, 또한 본 발명에서 사용되는 쇼팅바는 메일커넥터와 휘메일커넥터가 완전히 결합되면 정해진 두 단자를 접속시키고, 상기 양 커넥터가 환전히 결합되지 않으면 정해진 두 단자를 분리시키는 것이다. 이하, 본 발명의 한 실시예를 첨부된 도면을 참조해서 상세히 설명하면 다음과 같다.According to the present invention as described above, if the connector of the critical component is not correctly connected, the signal flow components are not normally operated, it is possible to simply check the connection failure. The shorting bar may separate two terminals when the male connector and the female connector are completely coupled, and connect the two terminals when the two connectors are not completely coupled. When the connector is fully coupled, the two terminals are connected, and when the two connectors are not exchanged, the two terminals are separated. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 의한 일실시예를 보인 회로도로서, 이에 도시된 바와같이 중요부품의 와이어 하네스를 연결하기 위한 중요부품 커넥터(10)에 시그널 부품 연결용 쇼팅바(11)를 설치하며, 전원(B+)단자가 휴즈(1)를 통하여 혼(Horn)제어용 릴레리(RY1)의 접점스위치에 연결되고, 그 접점스위치에 타단이 접지된 혼(2)에 연결되며, 상기한 휴즈(1)의 출력단이 중요부품의 와이어 하네스를 경유하도록 이루어진 중요부품 커넥터(10)의 쇼팅바(11)를 통하여 상기한 릴레이(RY1)의 코일 일단에 연결되고, 그 릴레이(RY1)의 코일 타단이 혼스위치(3)에 연결되어 구성된다.1 is a circuit diagram showing an embodiment according to the present invention, and as shown therein, a shorting bar 11 for connecting signal parts is installed on an important part connector 10 for connecting a wire harness of an important part. The (B +) terminal is connected to the contact switch of the horn control relay RY1 through the fuse 1, and is connected to the horn 2 having the other end grounded at the contact switch, and the fuse 1 described above. Is connected to one end of the coil of the relay RY1 through the shorting bar 11 of the connector of the important component 10 configured to pass through the wire harness of the critical component, and the other end of the coil of the relay RY1 is horn switch. (3) is connected and configured.

이와같이 구성된 일실시예에 의하면, 중요부품을 와이어 하네스를 연결하기 위한 중요부품 커넥터(10)에 시그널부품 연결용 쇼팅바(11)를 설치하고, 시그널 부품인 혼(2)을 연결할 때에 상기 한 중요부품 커넥터(10)의 쇼팅바(11)를 혼 구동용 릴레이(RY1)의 코일 전원 공급라인이 경유하여 릴레이 구동전원이 공급되도록 구성하였는바, 중요 부품 커넥터(10)가 정확히 결합된 경우에는 혼구동용 릴레이(RY1)의 코일 전원 라인이 쇼팅바를 통하여 정확히 결선되게 된다.According to one embodiment configured as described above, when the shorting bar 11 for signal part connection is installed in the critical part connector 10 for connecting the critical part to the wire harness and the horn 2 as the signal part is connected, The shorting bar 11 of the component connector 10 is configured such that the relay driving power is supplied via the coil power supply line of the horn driving relay RY1. When the important component connector 10 is correctly coupled, the horn The coil power line of the driving relay RY1 is correctly connected through the shorting bar.

이에 따라 혼 스위치(3)를 온 시키면 릴레이가 온되면서 혼이 정상동작을 하게 된다. 그리고, 중요 부품 커넥터(10)가 정확히 결합되지 않아 접촉불량이나 결합불량이 생긴 경우에는 혼 구동용 릴레이(RY1)의 코일 전원 공급 라인과 쇼팅바(11)와의 연결이 제대로 이루어지지 않게 되어 혼 스위치(3)를 눌러도 혼(2)이 작동되지 않는다. 따라서, 혼 스위치(3)를 눌러서 혼(2)이 정상동작 되면 중요 부품을 연결하는 와이어 하네스가 정상 연결된 것이고, 혼 스위치(3)를 눌러서 혼(2)이 작동되지 않으면, 중요 부품 커넥터(10)가 제대로 결합되지 않음을 쉽게 알수 있게 되는 것이다.Accordingly, when the horn switch 3 is turned on, the relay is turned on and the horn operates normally. In addition, in the case where the critical component connector 10 is not correctly coupled and a contact or coupling failure occurs, the connection between the coil power supply line of the horn driving relay RY1 and the shorting bar 11 may not be performed properly. Pressing (3) does not activate the horn (2). Therefore, when the horn 2 is operated normally by pressing the horn switch 3, the wire harness connecting the important parts is normally connected. If the horn 2 is not operated by pressing the horn switch 3, the important part connector 10 ) Is not easily combined.

한편, 본 발명의 다른 실시예로는 제2도에 도시된 바와 같이 점화 스위치(IG1)은 릴레이코일의 일단에 연결되고, 일반 전원(B+)단이 상기한 릴레이(RY11)의 접점 스위치를 통하여 타단이 접지된 상기한 방향지시등(22)에 연결되며, 상기 릴레이(RY11)의 코일 타단이 콤비네이션 스위치(23), 플래셔 유니트(24)를 통한후 별도로 구비된 체크 절환 스위치(25)의 공통단자(가동단자)에 연결되며, 그 체크 절환 스위치(25)의 오프단자는 접지되고, 온 단자는 중요 부품 커넥터(10)에 설치된 쇼팅바(11)를 경유하여 접지로 연결되도록 구성되어 있다.Meanwhile, in another embodiment of the present invention, as shown in FIG. 2, the ignition switch IG1 is connected to one end of the relay coil, and the general power source B + terminal is connected to the relay switch RY11 described above. The other end is connected to the above-mentioned direction indicator light 22 which is grounded, and the common end of the check switching switch 25 separately provided after the coil other end of the relay RY11 is provided through the combination switch 23 and the flasher unit 24. It is connected to the (moving terminal), the off terminal of the check switching switch 25 is grounded, and the on terminal is configured to be connected to the ground via the shorting bar 11 provided in the critical component connector 10.

즉, 중요 부품의 와이어 하네스를 연결하기 위한 중요 부품 커넥터(10)에 시그널 부품 연결용 쇼팅바(11)를 설치하고, 별도의 체크 절환 스위치(25)를 구비하여 방향 지시등(22) 제어용 플래셔 유니트(24)의 접지 루프상에 연결하고, 그 체크 절환 스위치(25)의 온접점이 상기한 중요 부품 커넥터(10)에 설치한 쇼팅바(11)를 경유하여접지되게 하고, 오프접점이 직접 접지되게 하여 비상시 체크절환 스위치(25)를 이용하여 방향지시등(25)을 점등시킬수 있도록 구성하였다.That is, the shorting bar 11 for signal part connection is installed in the critical part connector 10 for connecting the wire harness of the critical part, and the flasher unit for controlling the turn indicator 22 is provided with a separate check changeover switch 25. (24) connected to the ground loop, and the on-contact of the check changeover switch 25 is grounded via the shorting bar 11 provided in the above-mentioned critical part connector 10, and the off-contact is directly grounded. It was configured to turn on the direction indicator (25) using the check switch 25 in the emergency.

이와 같은 다른 실시예에서는 중요 부품의 와이어 하네스 연결상태를 체크하기 위한 신호류 부품으로 방향지시등(22)을 이용한 경우에 비상시 그 방향 지시등을 정상작동시키기 위한 것으로서 평소에 체크 절환 스위치(25)가 온접점에 단락된 상태이므로, 플래셔 유니트(24)의 접지 루프가 상기한 체크 절환스위치(25) 및 중요 부품커넥터(10)의 쇼팅바(11)를 경유하여 접지단에 연결된다.In such another embodiment, when the direction indicator 22 is used as a signal flow part for checking the wire harness connection state of the critical parts, the check change switch 25 is normally turned on in order to operate the direction indicator in an emergency. Since the contact is short-circuited, the ground loop of the flasher unit 24 is connected to the ground terminal via the shorting bar 11 of the check switch 25 and the critical component connector 10 described above.

이에따라 중요 부품 커넥터가 정상적인 결합상태인 경우에는, 점화 스위치(IG1)가 온 된 상태에서 콤비네이션 스위치(23)가 방향지시등 온으로 선택되면, 플래셔 유니트(24)의 작동에 의해 릴레이(RY11)가 주기적으로 단속제어되어 방향지시등의 주기적인 점등제어가 이루어 진다. 만약 주행중에 충격등으로 인하여 중요 부품 커넥터(10)의 결합불량이 발생되면, 쇼팅바(11)가 연결되지 않게 되어 콤비네이션 스위치(23)를 방향지시등 온 상태로 선택하여도 방향지시등(22)이 점등되지 않게 된다.Accordingly, in the case where the important component connector is normally engaged, if the combination switch 23 is selected as the turn indicator light on with the ignition switch IG1 turned on, the relay RY11 is periodically operated by the operation of the flasher unit 24. By intermittent control, periodic lighting control of direction indicator is performed. If the improper coupling of the important component connector 10 occurs during driving, the shorting bar 11 may not be connected, and the direction indicator 22 may be turned on even when the combination switch 23 is turned on. It will not turn on.

이와같이 커넥터(10)의 접속불량이 갑자기 발생하여 방향지시등(22)이 점등되지 않는 경우에는 사고의 위험이 발생되므로, 중요 부품 커넥터(10)의 연결불량임을 인식하여 운전자가 체크 절환 스위치(25)를 눌러 오프시킨다. 이에 따라 플래셔 유니트(24)가 상기한 체크 절환 스위치(25)의 오프단자를 통하여 접지 루프가 형성되므로, 콤비네이션 스위치(23)의 방향지시등 온 선택에 의해 방향지시등(22)이 점등되지 않게 되고, 주행중에 방향 지시등(22)이 점등되지 않으면 사고의 위험이 있으므로, 체크 절환 스위치(25)를 오프시킴으로써, 정상적으로 방향지시(22)등이 작동되게 하여 차량을 안전한 장소로 이동시킬수 있게 된다.In this way, when the connection failure of the connector 10 suddenly occurs and the direction indicator 22 does not light up, a risk of an accident occurs. Therefore, the driver recognizes that the connection of the important component connector 10 is poor and the driver switches the check switch 25. To turn it off. Accordingly, since the ground loop is formed by the flasher unit 24 through the above-described off terminal of the check changeover switch 25, the direction indicator 22 is not turned on by the selection of the direction indicator light on the combination switch 23, If the turn indicator 22 does not turn on while driving, there is a risk of an accident. By turning off the check switching switch 25, the turn indicator 22 can be normally operated to move the vehicle to a safe place.

이상과 같이 본 발명에 의하면, 중요부품의 와이어 하네스를 연결하기 위한 커넥터에 쇼팅바를 설치하고, 그 쇼팅바를 경유하여 신호류 부품이 연결되게 함으로써, 중요부품의 연결불량이 발생되며, 시그널 부품이 작동되지 않게 되어 고가의 자기진단회로를 설치하지 않고서도 운전자가 중요부품의 연결불량을 쉽게 확인할 수 있는 효과가 있고, 체크 절환스위치를 설치하여 주행중 중요부품의 연결불량이 발생되는 비상시에 체크 절환스위치를 절환시킴에 따라 기본적인 신호류 부품의 작동이 가능하게 할 수 있어서, 차량을 안전하게 안전장소로 이동시킬수 있는 효과가 있다.According to the present invention as described above, by installing a shorting bar in the connector for connecting the wire harness of the important parts, and by connecting the signal flow components via the shorting bar, the poor connection of the important parts occurs, the signal parts are operated The driver can easily check the connection failure of important parts without installing expensive self-diagnosis circuit, and check check switch is installed in case of emergency where the connection of important parts occurs while driving. By switching, it is possible to operate the basic signal components, there is an effect that can safely move the vehicle to a safe place.
