Abstract
A connection mechanism for connecting a pair of head suspension assemblies to a disc drive actuator arm in which the connection mechanism includes connection portions associated with respective load beams with such connection portions having cooperating, mating bosses extending into a mounting opening in the actuator arm and into interconnecting overlapping engagement with one another to result in an interference fit connection.
Claims11
A connection assembly for connecting a load beam to an actuator arm in a disc drive comprising:
- a first member having a first hollow cylindrical deformable boss, said first boss sized and adapted for being closely fitted both within a connection opening of a load beam and within a connection opening of an actuator arm from a first side thereof;
- and
- a second member having a second hollow cylindrical deformable boss, sized and adapted for being closely and securely nest-fitted within the first boss, when the first boss is fitted both within the connection opening of the first load beam and within the connection opening of the actuator arm from a side thereof;
- whereby, the close nest-fit between the bosses retains the load beam to the actuator arm.
A connection assembly for connecting a load beam to an actuator arm in a disc drive comprising:
- a first member having a first hollow cylindrical deformable boss of a first perpendicular height, sized and adapted for closely fitting both within a connection opening of a load beam and within an actuator arm opening from a proximal side thereof, said actuator arm opening located in a reduced perpendicular height portion of said actuator arm;
- and
- a second member having a second hollow cylindrical deformable boss of a second perpendicular height, sized and adapted for closely and securely nest-fitting within the first boss, when the first boss is fitted both within the connection opening of the first load beam and within the actuator arm opening from a distal side thereof;
- whereby the perpendicular height of the reduced height actuator arm portion is less than the sum of the perpendicular heights of the bosses, thereby assuring that the close nest-fit between the bosses securely retains the load beam to the actuator arm.
