Ultrasonic wave sensor for improving sensitivity through wire stripping process

Abstract

The invention relates to the field of obstacle detection sensors, in particular to an ultrasonic wave sensor for improving sensitivity through the wire stripping process. By means of the ultrasonic wave sensor for improving the sensitivity through the wire stripping process, twice commutation is cancelled, the problems of insufficient joint and electric lead breakage caused by twice commutation in the prior art are solved, and the problems that a product does not work and does not work continuously are solved on the premise that the functions of the products are achieved. According to the ultrasonic wave sensor for improving the sensitivity through the wire stripping process, a transit adapter plate in the prior art is abandoned, the wire at one end of the signal output positive electrode line is stripped, and the problems in the prior arts are solved,. The ultrasonic wave sensor for improving the sensitivity through the wire stripping process is applied in the field of ultrasonic wave sensing design of the ultrasonic wave sensor in an automatic parking system.

Description

technical field [0001] The invention relates to the field of obstacle detection sensors, in particular to an ultrasonic sensor whose sensitivity is improved by wire stripping. Background technique [0002] Ultrasonic sensors with integrated transceiver functions have been widely used as obstacle detection sensors such as vehicle parking systems. Such product structure as figure 1 As shown, such an ultrasonic sensor includes a cylindrical shell 1 with a bottom and a piezoelectric element 2, wherein the piezoelectric element 2 is attached to the inner side of the bottom of the cylindrical shell 1, so that the bottom of the cylindrical shell 1 has the function of a vibrating surface . The first sealant layer 5 is filled in the concave part formed by the adapter plate 8 (the function is to transmit the positive and negative signals of the signal transmission to the positive connection line 9 and the negative connection line 10 respectively) and the side wall of the cylindrical...
