摘要:
A short ring (80, 80A, 90) is mounted onto a back part of a housing (30) of an ultrasonic sensor (S) so that the short ring (80, 80A, 90) is coaxial with the housing (30). The width of the short ring (80, 80A, 90) along the axial direction of the housing (30) is set such it shields the back part of the housing (30) including a transformer (40b) of a processor (40). The short ring (80, 80A, 90) is made up of an excellent metal conductor and is coaxial with the coils (42b, 42g) of the transformer (40b).
摘要(中):
将短环(80,80A,90)安装到超声波传感器(S)的壳体(30)的后部,使得短环(80,80A,90)与壳体(30)同轴。 沿着壳体(30)的轴向的短环(80,80A,90)的宽度被设定为使得包围处理器(40)的变压器(40b)的壳体(30)的后部被屏蔽。 短环(80,80A,90)由优良的金属导体构成,与变压器(40b)的线圈(42b,42g)同轴。
