Description

  The present invention relates to a computer device such as a personal computer, and more particularly to a computer device in which an expansion board is connected to a main board.

  In a computer apparatus, an expansion board (expansion card) such as a graphic board is often added in order to complement and expand functions that can be realized by a main board (motherboard). The expansion board has a fixing portion (for example, a fixing bracket) and a terminal portion. The fixing portion is fixed to a predetermined portion (an expansion slot or an I / O panel) of the main body case with a screw or the like, and the terminal portion is fixed to the main board. It is mounted on a computer device by being inserted into a socket (for example, a PCI socket).

JP 7-221471 A

  Expansion boards in recent years tend to be larger and / or heavier due to an increase in the number of mounted components accompanying the advancement of functions and the integration of a cooling mechanism for removing the heat generation. In particular, a graphic board having a large processing capacity has a size larger than that of the main board and a large weight exceeding 1 kg.

  On the other hand, various external forces act on the computer device depending on the use environment. For example, when a computer device is shipped, vibration and impact due to delivery act, and in a computer device mounted on a movable part such as an industrial machine or a game device, the vibration or impact acts over the period of use of the product. In a computer device installed near a high output speaker in a game device or a concert hall, vibration due to sound may not be ignored.

  When the external force as described above acts on the computer device, the terminal portion, the socket, or the like may be worn or broken, leading to failure or quality degradation. In particular, in a large or heavy extension board, the load on the terminal portion or the like due to an external force increases, and the possibility of failure increases.

  From the above situation, there is a need for a computer device that can prevent or reduce the failure, deterioration, and quality degradation of the expansion board, main board, and / or its terminal and socket against external forces in delivery and harsh usage environments. ing.
