  • Patent number: 11683921
    Abstract: An insertion tool for assisting in the insertion of an OCP 3.0 type expansion card in an expansion card slot of a computer system is disclosed. The expansion card may be a pull tab type form factor that does not have a mechanism such as an ejector latch to assist in applying force to insert the card. The expansion card has a front panel opposite a distal edge connector. The tool has a handle and a head coupled to the handle. The head has two contact areas that contact different areas of the front panel of the expansion card. For example, one of the contact areas may be an extended side arm and the other area may be a lateral rib extending from the head.

  • Patent number: 11635791
    Abstract: A partition for separating computer components in an apparatus holding the computer components is provided. The partition includes a body with a first side and a second side; one or more top tabs projecting from both the first side and the second side of the body; one or more bottom tabs projecting from the first side of the body; and one or more bottom protrusions projecting from the second side of the body. The one or more top tabs are secured in a first manner, e.g., through rivets, to a first panel of the apparatus. The one or more bottom tabs are secured in the first manner to a second panel of the apparatus. The one or more bottom protrusions are secured in a second manner to the second panel of the apparatus, e.g., tucking a protrusion under the second panel. The features allow different-sized compartments for different storage form factors.

  • Publication number: 20210219452
    Abstract: A front-access chassis for storage drives can be configured to store different drives in different orientations in a single group of drives. For example, drives in a disk group can be installed with two vertical drives followed immediately by four horizontal drives. Each chassis can include multiple disk groups. Thus, drives with certain functions can be easily and readily identified based on orientation. For example, system drives may be installed vertically whereas storage drives may be installed horizontally, permitting a user to quickly identify a desired drive at a glance.

  • Patent number: 10925166
    Abstract: A fixture and method are directed to releasably couple the fixture to a semi-flexible printed circuit board (PCB)/printed circuit board assembly (PCBA) at a flexible PCB/PCBA portion. The fixture includes a body with a first arm and a second arm extending from a base, an interior surface of the first arm facing an interior surface of the second arm. A first ridge extends from the interior surface of the first arm and defines a first gap between the first ridge and the interior surface of the second arm. The first gap is sized to receive and support a flexible PCB/PCBA portion. At least one second ridge extends from the interior surface of the first arm and defines a second gap between the at least one second ridge and the interior surface of the second arm. The second gap is sized to receive and support a rigid PCB/PCBA portion.
