Abstract
In order to provide a unitary, rugged and simplified engine knock sensor assembly for internal combustion engines, which is readily tunable after manufacture to particular frequency characteristics of a given engine, the invention provides a cantilevered bending oscillator which is clamped together with a suitable electrical contact in an axial channel of a metallic cylindrical socket. The radial clamping forces are permanently provided by deformation of the socket material, for example by mortising, or other dimensional changes of the socket material. A number of embodiments is presented. The invention also includes a method for simultaneously producing two separate electrical contacts from a single contact element.
