Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the utility model provides a connection structure of radar board and circuit board, including circuit board 1 and radar board 2 of emergent down lamp, establish on circuit board 1 and keep away vacancy district 3 (circuit and electronic components in other regions in the circuit board 1 are all not drawn), keep away and do not set up electronic components on the vacancy district 3, radar board 2 establishes the position of keeping away in the dead zone 3 on circuit board 1, can ensure like this that circuit board 1 can not produce interference to radar board 2, make again and do not account for the space between circuit board 1 and the radar board 2, the signal is stable, the reliability is high.
As an embodiment, as shown in fig. 2, the clearance area 3 is further provided with a notch 4, the notch 4 is located at the edge of the circuit board 1, the front end of the radar board 2 is arranged on the circuit board 1, and the rear end of the radar board 2 extends above the notch 4, so that the electronic component cannot be arranged at the notch 4, the circuit board 1 is ensured not to absorb signals of the radar board 2, and the reliability is high.
As an embodiment, the projection of the notch 4 on the horizontal plane is L-shaped, the structure is simple, and the processing is convenient. Specifically, the axis of the horizontal plane projection of the radar plate 2 is parallel to one side of the notch 4, and the distribution is reasonable. In particular, the circuit board 1 is a circular-like plate, facilitating the provision of the notch 4.
As an embodiment, the circuit board 1 and the radar board 2 are welded through fitting, the radar board 2 is welded on the circuit board 1 through a chip mounter, and the connection is reliable and high in efficiency.
As an embodiment, the circuit board 1 is further provided with a connecting terminal 5, the radar plate 2 is welded on the circuit board 1 through the connecting terminal 5, the occupied space is small, and the connection is simple. Specifically, the connection terminals 5 are respectively located on the left and right sides of the radar plate 2, so that the connection between the radar plate 2 and the circuit board 1 is more reliable. Specifically, the number of the connecting terminals 5 is four, and two connecting terminals 5, namely a positive connecting terminal and a negative connecting terminal, are arranged on the left side of the radar plate 2; two connecting terminals 5, namely a grounding connecting terminal and an empty connecting terminal, are arranged on the right side of the radar plate 2.
