Problems solved by technology

[0006] However, in the conventional example stated above and Figure 4 In the case of the configuration shown in , it is necessary to use the cover member 105 to close the opening of the case 101
This creates the problem of increased parts count
In addition, costs such as equipment costs must be increased to abut the covering member 105 to the peripheral edge of the opening of the housing 105
This leads to higher costs such as depreciation charges

Abstract

An ultrasonic sensor includes a transceiver block having a transceiver device for transmitting and receiving ultrasonic waves, and a circuit board mounted with an electronic circuit for processing ultrasonic signals transmitted and received through the transceiver device. A housing of the ultrasonic sensor includes a storing portion having an opening. The circuit board is stored within the storing portion, and the opening of the storing portion is closed by the transceiver block.

Description

technical field [0001] The present invention relates to ultrasonic sensors mounted, for example, on motor vehicles for obstacle detection and the like. Background technique [0002] routinely, such as image 3 As shown in , an available ultrasonic sensor includes a hollow housing 101 having an opening on one surface thereof and a transceiving device (transceiving unit) 102 having a transceiving surface for transmitting and receiving ultrasonic waves, which is exposed on the other side of the housing 101. On the surface. The ultrasonic sensor includes an electronic circuit arranged in a casing 101 and installed for processing ultrasonic waves transmitted and received by the transceiver 102 , and a wiring cable 104 electrically interconnecting the transceiver 102 and the circuit board 103 . The ultrasonic sensor further includes a cover member 105 provided to cover the opening of the case 101, and a terminal 106 connected at one end to the electronic circuit of the circuit bo...
