Card connector

Abstract

A resin body (2) cooperates with a cover (3) made of sheet metal to form a slot (5) into which a memory card (100) is to be inserted. The resin body has an erroneous card insertion preventing thickened portion (22) into which a core member (24) made of a material that is higher in strength than the resin forming the body is embedded. The thickened portion (22) is positioned in an erroneous insertion preventing notch region of the memory card (100) that is to be inserted in a card attachment position of the slot (5) in a normal insertion posture, and is to butt against an insertion end face of the memory card (100) that is erroneously inserted in a posture different from the normal insertion posture, to block the insertion of the memory card (100) to a card set position. An end face (25) of the core member (24) is protruded from an end face (23) of the thickened portion (22).

Description

technical field [0001] The present invention relates to a card connector for electronically connecting a memory card with various electronic device substrates, which has a function of preventing incorrect card insertion. Background technique [0002] As we all know, in the existing card connector, as a mechanical means to prevent the card from being inserted into the card installation position of the socket by mistake in a posture other than the normal insertion posture, a stopper composed of a leaf spring as other parts is cantilevered. Installed on the cover, or cantilevered from the metal sheet cover that constitutes the cover with a resin matrix body in advance to form a stopper plate, so that the insertion end face of the card inserted by mistake in a posture other than the correct posture touches these The free end of stopper and stopper plate, prevents from inserting the card by mistake and inserts into the card installation position (for example, refer to " Japanese ...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing means for preventing mis-insertion, when the card is subjected to an excessive propulsion force, the card may be damaged due to the metal stopper and the free end of the stopper plate, and sometimes the free end of the stopper and the stopper plate may be damaged. The memory card becomes thorny, and the card may not be pulled out

Moreover, this situation will become more significant as the miniaturization of the card

[0004] On the other hand, if the part of the resin matrix body of the outer cover is thickened, so as to have a resisting surface that hits the card insertion end surface when it is inserted by mistake in a posture other than the normal insertion posture, it is possible to prevent the wrongly inserted card from being inserted into the card installation position. , although the above-mentioned problems can be solved, there are still problems such as difficulty in obtaining sufficient breaking strength of the abutting portion itself, and slippage of the card due to contact between the resin and the resin, so that it is difficult to obtain sufficient card mis-insertion prevention performance, etc.
