Disk drive head stack assembly with clip for mounting a flex cable
View Patent ↗A disk drive has a novel head stack assembly that includes a flex cable having a width, an actuator body, and a clip. A top portion of the clip includes a first top slot and a second top slot, forming a non-zero acute angle. The bottom portion of the clip includes a first bottom slot that is substantially aligned to face and oppose the first top slot, and a second bottom slot that is substantially aligned to face and oppose the second top slot. A first maximum distance between the first top slot and the first bottom slot equals or exceeds the width. A second maximum distance between the second top slot and the second bottom slot equals or exceeds the width. The slots retain the flex cable. The top portion and the bottom portion are a single monolithic piece.
1. A head stack assembly comprising:
a flex cable having a width;
an actuator body; and
a clip for mounting the flex cable to the actuator body, the clip including a top portion and a bottom portion coupled to the top portion by a member, the top portion including a first top slot and a second top slot therein, the first top slot and the second top slot forming a non-zero acute angle, the bottom portion including a first bottom slot and a second bottom slot therein, the first bottom slot being substantially aligned with the first top slot to face and oppose the first top slot, the second bottom slot being substantially aligned with the second top slot to face and oppose the second top slot, a first maximum distance between the first top slot and the first bottom slot equaling or exceeding the width; a second maximum distance between the second top slot and the second bottom slot equaling or exceeding the width;
wherein the first and second top slots and the first and second bottom slots retain the flex cable, and wherein the top portion and the bottom portion are a single monolithic piece rather than an assembly of sub-components; and
wherein the member resides between the first top slot and the second top slot and between the first bottom slot and the second bottom slot.
2. The head stack assembly of claim 1 wherein the angle is at least five degrees and not more than thirty degrees.
3. The head stack assembly of claim 2 wherein the angle is at least seven degrees and not more than seventeen degrees.
4. The head stack assembly of claim 1 wherein the clip is plastic.
5. The head stack assembly of claim 1 further comprising:
a metal stiffener fixed to the actuator body, the clip removably attached to the metal stiffener.
6. The head stack assembly of claim 1 wherein the clip forms a substantially I-shaped structure.
7. The head stack assembly of claim 1 wherein the clip has a height of two millimeters more than the width.
8. The head stack assembly of claim 1 wherein the first maximum distance is 0.025 mm more than the width.
9. The head stack assembly of claim 1 wherein the second maximum distance is 0.025 mm more than the width.
10. A disk drive comprising:
a base;
at least one disk coupled with the base; and
a head stack assembly coupled with the base, the head stack assembly including an actuator body having a mounting surface, a flex cable and a clip for attaching the flex cable to the mounting surface, the clip further including a top portion and a bottom portion coupled to the top portion by a member, the top portion including a first top slot and a second top slot therein, the first top slot and the second top slot forming a non-zero acute angle, the bottom portion including a first bottom slot and a second bottom slot therein, the first bottom slot being substantially aligned with the first top slot to face and oppose the first top slot, the second bottom slot being substantially aligned with the second top slot to face and oppose the second top slot, a first maximum distance between the first top slot and the first bottom slot equaling or exceeding the width; a second maximum distance between the second top slot and the second bottom slot equaling or exceeding the width;
wherein the first and second top slots and the first and second bottom slots are in contact with the flex cable, and wherein the top portion and the bottom portion are a single monolithic piece rather than an assembly of sub-components; and
wherein the member resides between the first top slot and the second top slot and between the first bottom slot and the second bottom slot.
11. The disk drive of claim 10 wherein the angle is at least five degrees and not more than thirty degrees.
12. The disk drive of claim 11 wherein the acute angle is at least seven degrees and not more than seventeen degrees.
13. The disk drive of claim 10 wherein the clip is plastic.
14. The disk drive of claim 10 wherein the mounting surface further includes a metal stiffener.
15. The disk drive of claim 10 wherein the clip has a height of two millimeters more than the width.
16. The disk drive of claim 10 wherein the first maximum distance is 0.025 mm more than the width.
17. The disk drive of claim 10 wherein the second maximum distance is 0.025 mm more than the width.
18. The disk drive of claim 10 wherein the clip forms a substantially I-shaped structure.
