기판 유동 방지 구조를 구비한 전자회로기판 유닛{PCB unit provided with pcb moving prevention structure}Electronic circuit board unit having a substrate flow prevention structure {PCB unit provided with pcb moving prevention structure}

본 발명은 차량용 전자회로기판 유닛에 관한 것으로서, 더욱 상세하게는 하우징에 수납된 전자회로기판을 안정적으로 지지하면서 차량 진동 발생시 전자회로기판의 유동을 방지할 수 있는 기판 유동 방지 구조를 구비한 전자회로기판 유닛에 관한 것이다. The present invention relates to an electronic circuit board unit for a vehicle, and more particularly, an electronic circuit having a substrate flow preventing structure that can stably support an electronic circuit board housed in a housing and prevent the flow of the electronic circuit board when a vehicle vibration occurs. It relates to a substrate unit.

일반적으로 전자회로기판(PCB:Printed Circuit Board)은 기판에 전기소자들을 실장하고 기판 표면에 전기소자 간 전기 접속을 위한 전도성 회로 패턴을 형성하여 구성되는 부품으로서, 가전제품이나 산업용 전기장치 등 대부분의 전기장치에 두루 사용되고 있는 주요 부품이다.Generally, a printed circuit board (PCB) is a component formed by mounting electrical elements on a substrate and forming a conductive circuit pattern for electrical connection between the electrical elements on the surface of the substrate. It is a major component that is widely used in electrical devices.

통상적으로 전자회로기판은 전자소자 간 회로를 구성하면서 다른 주변부품과도 전기적으로 연결되어 특정 기능을 수행하는 전자제품 및 전기장치를 구성하므로 기본적으로는 전자회로기판과 주변부품 간에도 커넥터 등을 통해 전기적으로 접속되어야 함은 물론이다. In general, electronic circuit boards are composed of electronic devices and electronic devices that perform specific functions by being electrically connected to other peripheral parts while constituting a circuit between electronic devices. Of course it must be connected.

또한 차량 등에는 전기소자들이 실장된 전자회로기판을 하우징에 수납하고 하우징 외측으로 전자회로기판과 외부 부품 간 전기 접속을 위한 커넥터(신호 입출력을 위한 커넥터)를 구비하여, 전자회로기판과 커넥터, 하우징이 하나의 독립된 유닛을 이루는 전자회로기판 유닛이 사용되고 있다.In addition, a vehicle includes an electronic circuit board on which electric devices are mounted, and a connector (connector for signal input / output) between the electronic circuit board and external components is provided outside the housing to provide an electronic circuit board, a connector, and a housing. Electronic circuit board units forming this one independent unit are used.

차량용 전자회로기판 유닛으로는 센서류 등 외부 부품으로부터 커넥터를 통해 각종 신호를 입력받게 되면 전자회로기판이 입력된 신호를 처리하고 연산하여 그 결과를 다른 외부 부품으로 출력하는 차량용 제어기(ECU:Electronic Control Unit)를 예로 들 수 있다. As a vehicle electronic circuit board unit, when various signals are input from a connector such as sensors, the electronic circuit board processes and calculates the input signal and outputs the result to another external component (ECU: Electronic Control Unit) ).

도 1은 차량용 전자회로기판 유닛의 일례를 나타내는 사시도이고, 도 2는 도 1의 선 'A-A'를 따라 취한 단면도로서, 종래기술에 따른 문제점을 설명하기 위한 도면이다.1 is a perspective view illustrating an example of an electronic circuit board unit for a vehicle, and FIG. 2 is a cross-sectional view taken along the line 'A-A' of FIG. 1, and is a view for explaining a problem according to the related art.

도시된 바와 같이, 전자회로기판 유닛(10)의 일측에는 신호의 입출력을 위한 커넥터(14)가 구비되는데, 이 커넥터(14)는 외부 부품과의 전기 접속을 위해 외부 커넥터가 접속되는 부분으로서, 커넥터 하우징(15) 내부에 외부 커넥터의 터미널과 접속되어 신호의 입출력이 이루어지는 복수개의 터미널(16)을 구비하여 구성된다.As shown, one side of the electronic circuit board unit 10 is provided with a connector 14 for inputting and outputting signals, the connector 14 is a portion to which the external connector is connected for electrical connection with external components, The connector housing 15 has a plurality of terminals 16 connected to terminals of an external connector to input and output signals.

또한 도면부호 18은 전자회로기판 유닛(10)의 외부에 형성된 브라켓을 나타내는 것으로, 이는 전자회로기판 유닛(10)을 차체 또는 외부 부품에 체결하기 위한 것이다.In addition, reference numeral 18 denotes a bracket formed on the outside of the electronic circuit board unit 10, which is for fastening the electronic circuit board unit 10 to a vehicle body or an external component.

도 2를 참조하면, 전기소자(13)들이 실장된 전자회로기판(12)이 하우징(11a,11b) 내에 수납되어 있고, 커넥터 하우징(15)의 터미널(16)들이 도체 수단(17)을 통해 전자회로기판(12)에 연결되어 접속되고 있다.Referring to FIG. 2, an electronic circuit board 12 on which electric elements 13 are mounted is housed in housings 11a and 11b, and terminals 16 of connector housing 15 are connected via conductor means 17. It is connected to the electronic circuit board 12 and connected.

이와 같은 차량용 전자회로기판 유닛(10)에서는 전자회로기판(12)과 커넥터 하우징(15)이 볼트(미도시) 등에 의해 체결된 상태로 하우징(11a,11b) 내에 수납되는데, 체결된 상태의 커넥터(14)와 전자회로기판(12)을 수납하여 상부 하우징(11a)와 하부 하우징(11b)을 조립할 경우 커넥터 하우징(15)이 양측 하우징(11a,11b)에 맞물리면서 고정되도록 되어 있다.In the vehicle electronic circuit board unit 10, the electronic circuit board 12 and the connector housing 15 are accommodated in the housings 11a and 11b in a state where the electronic circuit board 12 and the connector housing 15 are fastened by bolts (not shown). When the upper housing 11a and the lower housing 11b are assembled by storing the 14 and the electronic circuit board 12, the connector housing 15 is engaged with and fixed to both housings 11a and 11b.

그러나, 종래의 전자회로기판 유닛(10)에서는, 도 2에 나타낸 바와 같이, 커넥터(14)(커넥터 하우징)와 상부/하부 하우징(11a,11b) 사이, 전자회로기판(12)과 하부 하우징(11b) 사이 등에 조립을 위한 최소한의 갭이 존재하므로, 차량 주행 중 진동이 발생하게 되면 이 갭에 의한 유격만큼 커넥터(14)와 전자회로기판(12)이 흔들리게 된다.However, in the conventional electronic circuit board unit 10, as shown in FIG. 2, between the connector 14 (connector housing) and the upper / lower housings 11a and 11b, the electronic circuit board 12 and the lower housing ( Since there is a minimum gap for assembly between 11b) and the like, if vibration occurs while driving the vehicle, the connector 14 and the electronic circuit board 12 shake as much as the clearance caused by the gap.

이로 인해 소음이 발생함은 물론 전자회로기판(12)과 전기소자(13) 등이 손상되는 경우가 종종 발생하고 있다.
As a result, noise, as well as the electronic circuit board 12 and the electric element 13 is often damaged.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 하우징에 수납된 전자회로기판을 안정적으로 지지하면서 차량 진동 발생시 전자회로기판의 유동을 방지할 수 있는 기판 유동 방지 구조를 구비한 전자회로기판 유닛을 제공하는데 그 목적이 있다.
