ンサプラグ。[Claims for Utility Model Registration] A connector plug having a terminal of the electrode protruding inside is formed in a resin member that partially surrounds a sensor including a piezoelectric element having electrodes on both sides, and a female connector is attached to the connector plug. Please contact us closely,
In a knocking sensor that suppresses the vibration of the connector plug as much as possible, the bending elastic modulus is 10 x 10 4 that allows the resonance level to be added as noise to the sensor output to a minimum.
A knocking sensor plug characterized in that the connector plug is formed of a resin material having a value of Kg/cm 2 or less.
