Abstract
Apparatus for sealing the internal spindle motor bearing structure from the surrounding environment in a hard disc memory device. The motor includes a single low-cost part that seals both airflow paths, including both the bearings of the motor and around the wires. This single part acts as the electrical connector for the spindle motor as well as the seal. The invention consists of a single injection molded plastic connector with electrical contact members contained therein. Wires from the internal windings of the spindle motor pass through a hole provided in the connector housing and are terminated to the electrical contact members located within the connector. This hole is in turn sealed with a single drop of adhesive that is cured under the application of ultraviolet light. In a preferred embodiment, the spindle motor housing and connector are designed to form a press fit between the outer diameter of the circularly shaped connector housing and a groove in the motor housing provided for this purpose.
