Connector for memory card

Abstract

PROBLEM TO BE SOLVED: To provide a memory card connector capable of reliably preventing, with a simple structure, the insertion of a memory card in an improper posture, without carrying out any work on a case.SOLUTION: A leaf spring piece supported in a cantilevered manner is formed integrally with a cover. An erroneous insertion prevention plate on at least a free-end side of the leaf spring piece is inclined downward with respect to the cover such that a rear lateral surface of the erroneous insertion prevention plate faces the inner side of a card housing part in a manner perpendicular to an inserting direction of a memory card and crosses a movement track of an inclined surface of the memory card inserted in the card housing part. If the memory card is inserted in a regular posture, the inclined surface abuts on a lower portion of the rear lateral surface and pushes up the erroneous insertion prevention plate, but if the memory card is inserted in an improper posture, a flat surface abuts on the rear lateral surface, thus causing the erroneous insertion prevention plate to restrict the insertion of the memory card.

Description

technical field [0001] The present invention relates to a memory card connector for connecting a memory card housed in a card storage unit to an electronic device, and more specifically, to a memory card connector provided with a wrong insertion prevention mechanism that restricts the insertion of a memory card that is to be inserted in an incorrect posture. Connector for memory card. Background technique [0002] Before, such as Figure 8 As shown, in a memory card 10 such as a large SD card, an inclined surface 10a is formed on the front side in the insertion direction into the card storage portion. Such as Figure 11 As shown, in the memory card connector 100 connected to the memory card 10 formed with the inclined surface 10a, a mis-insertion prevention protrusion 101 and the like are formed at the portion notched by the inclined surface 10a of the memory card 10, thereby eliminating the need for previous Insertion of the memory card 10 inserted into the card storage p...

Problems solved by technology

[0006] On the other hand, in order to shield the contacts 102 and the memory card 10, the card receiving portion 103 is often covered by a cover 104 made of an elastic material such as a metal plate. 104 bends over the mis-insertion prevention protrusion 101, and may not be able to perform the mis-insertion prevention function

[0007] Moreover, since the mis-insertion prevention protrusion 101 needs to be arranged in the groove 11 not in contact with the memory card 10 behind the contact 102 in contact with the conductive sheet 12a, it cannot obtain a sufficient thickness for its insertion direction. Insufficient strength, so the memory card 10 inserted in an incorrect posture abuts against it and is easily damaged

[0008] In addition, it is necessary to form the tiny protrusions 101 with high precision on the inner surface of the housing constituting the card housing portion 103, and the mold structure for manufacturing the housing becomes complicated, requiring strict manufacturing precision.
