Electrical connection to a coil spring through a local interference fit for connection to a vibratory rotation sensor and method of forming the same

摘要

An electrical connection between a vibratory rotation sensor and a hermetic header which makes use of a local interference fit to provide a high degree of mechanical isolation between the sensor and the header. The electrical connection includes an electrical pin extending from the header which is connected to the sensor through a coil spring. The pin includes an enlarged portion having a maximal dimension greater than an inner diameter of the coil spring to provide an interference fit between the coil spring and the pin. The degree of interference is variable controlled by selecting the dimensions of the enlarged portion of the pin and the coil spring. The degree of mechanical isolation between the header and sensor can also be chosen by selecting the location of the enlarged portion along a length of the pin. This provides a reliable electrical connection which maintains a high degree of mechanical isolation.
