Definitions

  • Electronic devices including computing devices, may include expansion cards, system cards, or other components which may provide additional or enhanced functionality to the electronic device. Such components may be engaged with or installed into the electronic device through the use of expansion slots or other connectors. Such slots or connectors may sometimes be disposed within the electronic device and/or be attached to a system board of the electronic device.
  • FIG. 1 A is a perspective view of an example card retainer in an open position.
  • Fig. IB is another perspective view of the example card retainer of Fig. 1A.
  • FIG. 1C is another perspective view of the example card retainer of Fig. 1A disposed in a closed position.
  • FIG. 2 is a perspective view of another example card retainer.
  • FIG. 3A is a perspective view of an example system board having an example cad retainer.
  • Fig. 3B is another perspective view of the example system board and card retainer of Fig. 3A.
  • FIG. 4 is a perspective view of an example computing device having an example card retainer.
  • Electronic devices may include expansion cards, system cards, or other components which may provide additional or enhanced functionality to the electronic device.
  • such components may be used to supplement existing components of the device, e.g., increase the storage capacity of the electronic device.
  • Such components may be engaged with or installed into the electronic device through the use of expansion slots or other card connectors.
  • Such slots or card connectors may sometimes be disposed within the electronic device and/or be attached to a motherboard, a riser card, or other type of system board of the electronic device.
  • Such components may have an edge connector having pins such that, upon the edge connector, and thus the component itself, being engaged with a card connector or slot of the electronic device, the pins on the edge connector may be engaged with complementary pins in the slot or connector, thereby enabling electronic communication between the system board and the expansion card or component.
  • the edge connector of the expansion card or component may be disposed on a single edge, or portion thereof, of the component.
  • the expansion card or component may merely be constrained by the engagement of the edge connector with the slot or card connector of the system board, thereby leaving the other edges of the expansion card free or cantilevered along the system board. This may create an insecure attachment of the expansion card to the system board, wherein the expansion card may wobble, vibrate, or otherwise move or loosen from the connector or slot, thereby negatively affecting the function of the card.
  • An expansion card may have a first end comprising the edge connector, and a second end opposite the first end.
  • the first end may be referred to as a connector end and the second end may be referred to as a free end, since it is not engaged with the connector or slot.
  • the free end may be fixed or constrained to the system board or another component of the electronic device by a fastener so as to provide a more secure attachment of the expansion card to the device.
  • fasteners may directly or indirectly secure the free end of the expansion card to an aperture, a mounting standoff, or other fastening or attachment feature of the system board or other component.
  • a tool such as a screwdriver may be used to install and remove the fastener from the attachment feature, and thus from fixing the free end of the expansion card in place. Therefore, any time a user may wish to install, swap, upgrade, or otherwise add or remove an expansion card to a computer system, the user may have to have a tool capable of installing and removing the fastener. This may be inconvenient to the user. Additionally, tools may be too large to access certain interior portions of a computing device, making installing or removing an expansion card very difficult. Therefore, it may be desirable for an electronic device, or a system board thereof, to have a simple way of securely fastening and removing a system card or supplemental component to or from the system board that may omit the need for tools.
  • Implementations of the present disclosure provide card retainers that may securely attach an expansion card or other supplemental component to an electronic device, or a system board thereof. Further, examples described herein may be able to secure a free end of an expansion card to a system board or other component without the use of a tool.

Abstract

Dans un exemple, un dispositif de retenue de carte peut comprendre une base pour recevoir une extrémité libre d'une carte d'expansion, une pince élastique disposée sur une partie centrale de la base pour venir en prise avec une entretoise pour fixer la base à l'entretoise, et un verrou fixé de façon pivotante à la base au niveau d'une première extrémité distale. Le verrou peut se verrouiller de manière amovible sur une seconde extrémité distale de la base lorsque le verrou est disposé dans une position fermée. Lorsqu'il est disposé dans la position fermée, le verrou peut retenir l'extrémité libre de la carte d'expansion.
