ABSTRACT:
A flexible cable is supported within the sealed disc drive housing, with one end of the cable readily, automatically soldered to the end wires of the spindle motor leads. The opposite or outboard end of the cable terminates in a header comprising a plastic mounting piece to support a multi-pin electrical connector with the pins extending from both sides of the header. Two locating pins are provided on the plastic header outside of a channel for defining the location of a gasket. The conductors in the cable terminate at four connecting pins at one end of the header. With the pins extending both above and below the header piece, immediately upon installation of the printed cable, the conductors to the spindle motor may be accessed so that the spindle motor and other elements of the head disc assembly may be tested during assembly of the complete disc drive. The locating pins provided at opposite ends of the header allow the printed circuit cable and header to be quickly and automatically disposed on the base surface of the housing casting, with the locating pins being pushed into recesses in the base housing casting, and the connecting pins extending through an opening in the base housing casting so that wires may be attached thereto to interface the header to external circuits supported on the exterior of the housing. A gasket is located in the channel surrounding the pins on the header to seal the interior of the disc drive so that the contaminant-free nature of the interior of the housing is preserved.
