ABSTRACT:
An improved spindle motor connector for a disc drive. The spindle motor connector includes a central housing having socket connectors for mating engagement with connector pins of the spindle motor. Electrical leads are connected to the socket connectors and extend radially from the central housing, and spoke arms are connected to the central housing and extend radially from the central housing adjacent the electrical leads. Spacer arms are connected to the spoke arms and maintain the desired spacing between the spindle motor connector pins and a disc drive printed wiring assembly, which is mounted below the spindle motor. The connector pins of the spindle motor are located at an end of and within the axial extent of a spindle motor stator shaft, so that the central housing extends into the end of the stator shaft. The end of the stator shaft extends through a hole in the disc drive printed wiring assembly. The spindle motor connector spans the hole in the disc drive printed wiring assembly and the distal ends of the leads of the spindle motor connector are soldered to the printed wiring assembly adjacent the spacer arms.
