Vehicle radar sensor assembly
First Claim
1. A sensor assembly comprising:
- a housing having a bottom surface and a plurality of side walls which define an interior recess region, said housing having a shoulder region projecting from the bottom surface and the side walls around a perimeter of the interior recess region;
an electrical interface projecting from the a top surface of the shoulder region;
an electrical shield disposed in the recess region of said housing, said electrical shield having a size and shape selected such that when said electrical shield is disposed in the housing, a first surface of a perimeter region of said electrical shield rests upon a top surface of the shoulder region of said housing to support said electrical shield in said housing and a second surface of the perimeter region of said electrical shield is in proximity to a side surface of the shoulder region and wherein said electrical shield is provided having one opening in the surface of the perimeter region through which at least a portion of said electrical interface projects when said electrical shield is disposed in said housing and wherein a bottom surface of said electrical shield does not have any openings provided therein;
a radar electronics module disposed over said electrical shield and electrically coupled to said electrical interface;
a radome disposed over said radar electronics module and coupled to the sidewalls of said housing; and
a breather vent disposed in said radome.

Abstract
A radar electronics module includes a support structure having a first surface having a plurality of recesses with a transmitter circuit board and a receiver circuit board disposed thereon. The transmitter and receiver circuit boards are disposed over the first surface of the supports structure such that transmitter and receive circuits are disposed in cavities on the support structure. The radar electronics module further includes a digital/power supply circuit printed wiring board (PWB) disposed on a second surface of the support structure and a connector disposed on the support structure. The connector is disposed in such a way that it provides electrical connections for at least one of power signals, analog signals or digital signals between at least two of the digital/power supply PWB, the transmitter circuit board and the receiver circuit board.

15. A method for assembling a sensor assembly comprising:
-
(a) attaching a transmitter circuit board, a receiver circuit board, and absorbers to a PWB frame; (b) disposing a header on the PWB frame and electrically coupling header pins to corresponding connection points on the transmitter and receiver circuit boards; (c) with the header and the transmitter and receiver circuit boards coupled to the frame, disposing the digital/power supply circuit board on the frame such that the header pins mate with holes and pads provided in an interface region of a digital/power supply circuit board; (d) electrically coupling header pins to corresponding electrical connection points on the digital/power supply circuit board; (e) securing a shield and a radar electronics module to a housing; (f) once the shield and the radar electronics module are secured in the housing, securing a radome to the housing. - View Dependent Claims (16, 17, 18, 19, 20)
