る。 In the accompanying drawings, 1 is a transducer that transmits and receives ultrasonic waves. The case of the vibrator 1 is made of aluminum or the like, and is electrically connected to the vibrator electrode 3a. The vibrator 1 is press-fitted into a vibration-proof rubber 2. 2 is a conductive anti-vibration rubber, which is made of silicone rubber containing an appropriate amount of carbon.
The anti-vibration rubber 2 is press-fitted into the main body 4 of the attachment part, and is fixed to the main body 4 of the attachment part by a vibration-proof rubber pressing plate 5. And the vibration isolating rubber 2 is the case electrode 3a.
By applying a voltage to the electric wire 6, electric power is supplied and heat is generated. 3a and 3b are vibrator electrodes, which are welded to the vibrator holding plate 7. By welding the vibrator holding plate 7 to the vibrator electrodes 3a and 3b, the vibration isolating rubber 2 is held between the vibrator holding plate 7 and the case of the vibrator 1. 8 is an electrode, which is connected to the electric wire 6. The electrode 8 has a ring shape and is fitted into the vibration isolating rubber 2, and is fixed to the vibration isolating rubber 1 and the mounting body 4 in a sandwiched manner.

術を提供することができる。 Depending on the weather, dew drops may adhere to the front surface of the vibrator 1 disposed outside. When a voltage is applied to the conductive anti-vibration rubber 2 covering the side and back surfaces of the vibrator 1, it generates heat and evaporates the dew droplets. When the vibration isolating rubber 2 generates heat, the vibrator 1 is heated, thereby preventing freezing and making the ultrasonic transducer usable in a place where the outside temperature is below freezing.
Note that by keeping the temperature of the vibrator 1 constant due to the heat generated by the vibration isolating rubber 2, it is possible to improve accuracy with respect to temperature. In addition, the vibrator 1 receives external vibrations propagating from the mounting body 4 and is received as noise by the ultrasonic receiver. , reduce noise. Further, in the dew drop prevention device for an ultrasonic vibrator according to the present invention, the vibration isolating rubber 2 is press-fitted into the vibrator 1, and the mounting body 4 is press-fitted into the vibration-proofing rubber 2, so that water droplets etc. It is possible to provide a technique for creating a vibrator 1 with excellent waterproof properties without infiltration between the vibrator 1 and the attachment body 4.
