Disk drive head suspension distal non-op shock limiter with branched arms

摘要

A head suspension assembly for a disk drive includes a load beam extending from a load beam supported end to a load beam distal end, and a laminated flexure supported by the load beam. The laminated flexure includes a structural layer having a head mounting tongue, a conductive layer having a plurality of patterned traces, and a dielectric layer between the structural layer and the conductive layer. The structural layer of the laminated flexure includes a distal limiter that has a first limiter arm and a second limiter arm adjoining at a distal apex. The distal apex is disposed closer to the load beam distal end than is the head mounting tongue. Each of the first and second limiter arms splits into a plurality of branches.

1. A head suspension assembly comprising:
a load beam extending from a load beam supported end to a load beam distal end; a laminated flexure supported by the load beam, the laminated flexure including
a structural layer having a head mounting tongue,a conductive layer having a plurality of patterned traces leading to connection terminals adjacent the tongue,a dielectric layer between the structural layer and the conductive layer; wherein the structural layer of the laminated flexure includes a distal limiter that has a first limiter arm and a second limiter arm, the distal limiter being disposed closer to the load beam distal end than is the head mounting tongue; and wherein each of the first and second limiter arms includes an opening that has a closed periphery and is adjacent the connection terminals.
