Description

  The present invention relates to a card adapter that is used when a card smaller than a predetermined card is mounted on a card connector to which a predetermined card is mounted, and is mounted on the card connector in a state where the small card is mounted.

  As a conventional card adapter, for example, there is a conventional technique disclosed in Patent Document 1. This prior art includes a case in which an upper case member and a lower case member are combined, and a card mounting portion for mounting a card is formed between the upper case member and the lower case member. The lower case member has both side wall portions that form the left and right side portions of the card mounting portion, and a bottom plate portion.

In this type of card adapter, the lower case member is produced by molding a resin.

  [2] The invention according to [1], wherein the bottom plate member and the frame are integrated by insert molding.

  The present invention configured as described above can simultaneously fix the bottom plate member to the frame and form the frame.

  [3] The present invention provides the invention according to [2], wherein a side edge portion of the bottom plate member is raised by bending to form an embedded portion embedded in the frame body, and a plurality of openings are provided in the embedded portion. It is characterized by that.

  In this invention comprised in this way, since the embedding part of a baseplate member has stood | started up, the embedding part of a baseplate member can be reliably embed | buried in a frame. Further, the embedded portion can be firmly fixed to the frame body by the plurality of openings.

  [4] The present invention is the invention according to [1], wherein an insertion port for the card to the card mounting portion is provided on an end surface of the case, and upper edges of the insertion port are on both side walls of the frame body. It is characterized by being formed by a metal bridge section that is spanned between the sections.

  According to the present invention configured as described above, the force when the inserted card is squeezed can be received by the metal bridge. Thereby, the case can be prevented from being damaged when the card is inserted, and the card can be smoothly inserted.

  [5] The invention according to [4] is characterized in that the bridge portion has a rib.

  The present invention configured as described above can improve the strength of the bridge portion.

  [6] The present invention is characterized in that, in the invention described in [4], the bridge portion and the frame body are integrated by insert molding.

  According to the present invention configured as described above, the fixing of the bridge portion to the frame body and the molding of the frame body can be performed simultaneously.

  [7] The present invention is characterized in that, in the invention according to [6], the embedded portion of the bridge portion embedded in the frame body is suspended by bending.

  In this invention comprised in this way, since the embed | buried part of the spanning part hangs down, it can be reliably embed | buried in a frame.

  [8] The present invention is characterized in that, in the invention described in [4], the bridge portion and the bottom plate member are integrally formed.

  In the present invention configured as described above, it is not necessary to increase the number of parts even if a metal bridge is provided.

  In the present invention, it is possible to easily reduce the thickness of the case by reducing the thickness of the bottom plate member. Thereby, it can contribute to thickness reduction of a card adapter.
