Description

  The present invention relates to a memory card connector device for inserting a memory card in a personal computer or the like, and more particularly to a memory card connector device having a memory card removal prevention mechanism.

  As a memory card connector device in which a memory card is prevented from being removed from the memory card holder by a memory card removal prevention material, for example, as shown in FIGS. 8 and 9, a cover is provided on a card connector portion 101 formed in a substantially U-shape. When the memory card 104 is inserted into the memory card holder 103 formed by attaching the portion 102, the tip 105 a of the leaf spring 105 provided on the cover portion 102 is engaged with the recess 106 provided on the memory card 104. The memory card 104 is prevented from being detached from the memory card holder 103, and when the memory card 104 is further pressed in the back direction, the engagement between the tip 105a of the leaf spring 105 and the recess 106 is achieved. Is released and the memory card 10 is There is known one having an eject mechanism which is to be extruded (e.g. Patent Document 1).

By the way, the memory card used in the OA personal computer emphasizes the operability of insertion / extraction, the card itself protrudes from the appearance of the device, and often does not take measures to prevent the card from being removed. However, FA personal computers often have poor installation environments and often require measures to prevent disconnection. When the memory card is mounted on the inside of the device without protruding from the device appearance in the FA personal computer, a memory such as a rubber cushion material is provided on the inner surface of the side wall 107a of the device housing 107 as shown in FIGS. A card removal prevention material (hereinafter referred to as a rubber cushion material) 108 is attached to prevent the memory card 104 from coming off. If you want to make the card pop out of the device appearance with emphasis on operability like an OA personal computer, there are no restrictions on the use because there is no hold down, and there is a caution such as “the card may come off” I need it. A presser is required when using it for FA personal computers.
