레이더는 전파를 사용하여 주위에 있는 사물의 거리와 방향, 그리고 속도 등을 검출해주는 센서이다.Radar is a sensor that uses radio waves to detect the distance, direction, and speed of objects around you.
도 1은 종래의 레이더 모듈을 도시한 것이다. 1 illustrates a conventional radar module.
도 1을 참고하면, 종래의 레이더 모듈은 안테나가 마련되는 안테나 인쇄회로기판과 제어회로(140)가 마련되는 제어회로 인쇄회로기판(130)을 포함한다.Referring to FIG. 1, a conventional radar module includes an antenna printed circuit board on which an antenna is provided and a control circuit printed circuit board 130 on which a control circuit 140 is provided.
안테나 인쇄회로기판(110)에는 레이더 전면으로 안테나(120)가 마련(실장)된다. 제어회로 인쇄회로기판(130)에는 레이더 전면 방향 및/또는 레이더 후면 방향으로 레이더 모듈의 제어에 필요한 전자부품들인 제어회로(140)가 마련된다.An antenna 120 is provided (mounted) on the front surface of the radar on the antenna printed circuit board 110. The control circuit printed circuit board 130 is provided with a control circuit 140 which is electronic components necessary for controlling the radar module in the radar front direction and / or radar rear direction.
그리고, 안테나 인쇄회로기판(110)에는 안테나 관통홀(150)이 마련되고, 제어회로 인쇄회로기판(130)에는 제어회로(140) 관통홀(160)이 마련된다.An antenna through hole 150 is provided in the antenna printed circuit board 110, and a control circuit 140 through hole 160 is provided in the control circuit printed circuit board 130.
안테나 관통홀(150)과 제어회로(140) 관통홀(160)에는 연결커넥터(170)가 마련되어, 납 등을 이용하여 연결커넥터(170)를 안테나 관통홀(150)과 제어회로(140) 관통홀(160)에 결합하여 연결커넥터(170)와 레이더 인쇄회고기판, 연결커넥터(170)와 제어회로 인쇄회로기판(130)을 전기적으로 연결한다. The connecting connector 170 is provided in the antenna through hole 150 and the control circuit 140 through hole 160 to penetrate the antenna through hole 150 and the control circuit 140 using lead or the like. It is coupled to the hole 160 to electrically connect the connector 170 and the radar printed circuit board, the connector 170 and the control circuit printed circuit board 130.
이는 안테나 인쇄회로기판(110)과 제어회로 인쇄회로기판(130)을 연결커넥터(170)를 이용하여 전기적으로 연결하는 것이다. This is to electrically connect the antenna printed circuit board 110 and the control circuit printed circuit board 130 using the connection connector 170.
레이더 모듈에서 안테나(120)의 유요한 전파는 레이더의 전면 방향으로 송신되고 수신되어야 한다. 그러나, 레이더 모듈이 레이더 후면의 노이즈에 유출되면 레이더가 오동작을 하는 원인이 된다. 이런 현상을 막기 위해서 일반적 레이더의 후면에 쉴드캡(180)을 고정하거나 실장한다. The useful radio waves of antenna 120 in the radar module must be transmitted and received in the front direction of the radar. However, if the radar module leaks into the noise behind the radar, the radar may malfunction. In order to prevent this phenomenon, the shield cap 180 is fixed or mounted on the rear of a general radar.
쉴드캡(180)은 전자파 등을 전기적으로 차폐를 시킨다. 즉, 쉴드캡(180)은 레이더 모듈에서 후면의 전기 및 전자적인 잡음의 영향을 최소화 시키는 역할을 수행한다.The shield cap 180 electrically shields electromagnetic waves and the like. That is, the shield cap 180 serves to minimize the influence of the electrical and electronic noise of the rear in the radar module.
이와 같은 종래의 레이더 모듈 구조는 레이더 후면의 잡음을 효과적으로 차단하는 장점이 있지만, 안테나와 제어회로(140)를 별도의 인쇄회로기판으로 제작하여 연결하기 때문에 제작과정이 복잡하고 제품의 두께가 두꺼워 지는 단점을 가지고 있었다. Such a conventional radar module structure has the advantage of effectively blocking noise on the rear of the radar, but because the antenna and the control circuit 140 is manufactured by connecting to a separate printed circuit board, the manufacturing process is complicated and the thickness of the product becomes thick Had a downside
또한, 종래의 레이저 모듈은 쉴드캡(180)이나 이와 유사한 기능을 하는 케이스를 반드시 붙여야 하기 때문에 제작비용이 상승하고, 제어회로(140)의 일부 전자부품을 쉴드캡(180)이 덥고 있어서 수리가 어려운 단점을 가지고 있었다.In addition, in the conventional laser module, since the shield cap 180 or a case having a similar function must be attached, the manufacturing cost increases, and the shield cap 180 is hot for some electronic components of the control circuit 140. Had a difficult downside
