Description

  The present invention relates to a card mounting apparatus and electronic equipment, and more particularly to a card mounting apparatus and electronic equipment for mounting an expansion card on a motherboard.

  A card edge connector is generally known as a card mounting apparatus for mounting an expansion card on a motherboard. This card edge connector has a structure in which an expansion card is inserted and removed from a direction perpendicular to the surface of the motherboard. For this reason, an electronic device equipped with a card edge connector has to secure an area for inserting and removing an expansion card from the vertical direction, which limits the degree of design freedom.

  Therefore, in order to improve the degree of freedom in design, for example, Patent Document 1 discloses a board mounting housing and a board mounting method. The technique described in Patent Document 1 can be inserted and removed by sliding the expansion card along the surface of the motherboard. As a result, the technique described in Patent Document 1 does not necessarily require an area for inserting and removing an expansion card in the vertical direction, and can improve the degree of freedom in design.

As a result, the technique described in Patent Document 1 may cause the expansion card to be worn when the expansion card is inserted or removed, thereby damaging the expansion card.

  Accordingly, an object of the present invention is to provide a card mounting apparatus and an electronic apparatus that can prevent damage to an expansion card by suppressing wear of the expansion card when the expansion card is inserted and removed.

  In order to achieve the above object, a card mounting apparatus according to the present invention sandwiches a first plate-like member via a loosely-fitted spherical member, and a sandwiching portion disposed on the second plate-like member. It is characterized by having.

  In order to achieve the above object, an electronic apparatus according to the present invention comprises the card mounting device and the second plate member.

  According to the present invention, it is possible to prevent the expansion card from being damaged by suppressing the wear of the expansion card when the expansion card is inserted and removed.
