Abstract
An apparatus includes a drive base. A drive cover overlies the drive base. A fastener secures the drive cover to the drive base. The fastener extends through the drive cover and into the drive base. A gasket is between the drive base and the drive cover. The gasket is compressed by the drive base and the drive cover. A spring feature is formed in the drive cover. The spring feature exerts a first force on the fastener and a second force on the base. The first force is opposite the second force.
Claims17
An apparatus comprising:
- a drive base;
- a drive cover overlying the drive base;
- a fastener securing the drive cover to the drive base, wherein the fastener extends through the drive cover and into the drive base;
- a gasket between the drive base and the drive cover, wherein the gasket is compressed by the drive base and the drive cover;
- and
- a spring feature formed in the drive cover, wherein
- the spring feature exerts a first force on the fastener and a second force on the base,
- the spring feature exerts the first force in a first region surrounding the fastener,
- the spring feature exerts the second force in a second region surrounding the first region, and
- the first force is opposite the second force.
An apparatus comprising:
- a storage device cover overlying a storage device base;
- a first region of a spring feature in the storage device cover exerting a first force on a loosened fastener, wherein
- the first region extends around the loosened fastener, and
- the first region stretches away from the storage device base to form a gap between the first region and the storage device base, wherein the spring feature exerts the first force on the loosened fastener;
- a second region of the spring feature in the storage device cover exerting a second force on the storage device base, wherein
- the first force and the second force are in opposing directions,
- the second region extends around the first region, and
- the second region is in overlying contact with the storage device base;
- and
- a gasket between the second region and a storage device, wherein the gasket is compressed by the storage device cover and the storage device base.
A method comprising:
- positioning a cover over a base and a gasket between the cover and the base, wherein
- the cover includes a cover fastener hole, and
- the cover includes a spring region extending away from the base around the cover fastener hole;
- inserting a fastener to a first position through the cover fastener hole and into the base, wherein
- the spring region remains extending away from the base and exerts a first force on the fastener,
- the cover and the base are in overlying contact in a contact region around the spring region, and
- the inserting compresses the gasket to a compressed height;
- and
- further inserting the fastener to a second position through the cover fastener hole and further into the base, wherein
- the further inserting flattens the spring region and brings the spring region of the cover into overlying contact with the base,
- the spring feature exerts a second force on the base,
- the spring feature exerts the first force in a first region surrounding the fastener,
- the spring feature exerts the second force in a second region surrounding the first region, and
- the compressed height of the gasket remains the same in response to the further inserting.
