Connector for memory card

Abstract

PROBLEM TO BE SOLVED: To provide a memory card connector capable of accurately positioning two types of memory cards with different outer shape sizes in any arbitrary location along a plane of a card tray on the one card tray.SOLUTION: A peripheral frame 7d forming an opening of a card mounting recess is formed into a contour that positions a large-sized memory card in orthogonal two directions along a plane of a card tray. Within the card mounting recess, there are disposed an actuator plate 5 which is disposed to be freely movable back and forth in a thickness direction and of which the ring-shaped inner edge is formed into a contour positioning a small-sized memory card in orthogonal two directions along the plane of the card tray; and energizing means 8 for energizing the actuator plate in a direction of the opening of the card mounting recess. The large-sized memory card pushes down the actuator plate and is positioned on the card tray by the opening of a card mounting part, and the small-sized memory card is positioned on the card tray by the ring-shaped inner edge of the actuator plate. The memory cards are then connected to a contact opposing the inside of a card connecting recess housing the card tray therein.

Description

technical field [0001] The present invention relates to a memory card connector for inserting one of two types of memory cards with different shapes into the same card connection recess of an electronic device and connecting them to contacts facing the card connection recess. Position the chuck supporting the two types of memory cards, and the memory card connector that connects one of the two types of memory cards to the contact on the electronic device side. Background technique [0002] As a card-like storage medium, an IC card or a memory card (hereinafter, including an IC card, referred to as a "memory card") with a built-in semiconductor element, along with the miniaturization of electronic devices connected to the memory card, has maintained interchangeability and made its Memory cards with reduced form factors have been developed in order, such as SIM cards that store unique ID information connected to mobile phones, from the largest first-generation SIM cards to min...

Problems solved by technology

[0015] Also, if Figure 15 As shown in (b), in the card mounting recess 102 that only surrounds the three sides of the compact memory card 132, there is a concern that the compact memory card 140 will fall off from the remaining side. In the case of positioning, there is a problem that it is difficult to take out the small memory card 132 from the chuck 101

[0016] On the other hand, in the latter memory card connector 110, the small memory card 142 is positioned in the card mounting recess 112 only by the small card positioning portion 114 above and to the right, and the large memory card 140 is positioned in the card mounting recess 112 only by the above and right. The guide part 113 and the large card positioning part 115 on the left are positioned in the card installation recessed part 112, so they are easy to move towards the remaining other directions, and cannot be reliably positioned and supported on the chuck 111 in the orthogonal directions of up, down, left, and right.

The small card positioning portion 114a abutting against the right side of the small memory card 142 and the large card positioning portion 115a abutting against the left side of the large memory card 140 are set to have concavo-convex contours on the sides of the small memory card 142 and the large memory card 140. The fitted shape also serves as positioning in the up and down direction, but the other side in the left and right direction is open, so it is not sufficient, and it is only applicable to the large memory card 140 and the small memory card 142 with uneven contours.

[0017] In addition, the chuck 111 is accommodated in the card mounting recess, and is electrically connected to contacts on the electronic device side through the window hole 116 of the chuck 111. For this structural reason, the relative position of the window hole 116 to the outer shape of the chuck 111 is determined. On the other hand, the small card positioning portion 114 or the large card positioning portion 115 is only formed along the two sides of the inner peripheral edge of the card installation recess 112, and it is necessary to use the small card positioning portion 114 or the large card positioning portion 115 to make the two kinds of Each electrode of the large memory card 140 and the small memory card 142 faces the window hole 116 and is positioned in the card mounting recess 112. Therefore, the shape of the card mounting recess 112 relative to the window hole 116 or the small card positioning portion 114 or the large card positioning portion The position or shape of 115 is restricted, and sometimes the shape of large memory card 140 and small memory card 142 cannot be applied
