By means of the effect of the rear bearing portions of the pressure boards, the inserted memory card touches only the matching metal terminals and the other metal terminals that do not match are kept away from the inserted memory card, preventing damage. | 04-23-2009 |
20100120281 | Card connector capable of detecting card insertion - A card connector capable of detecting card insertion includes a base frame, a cover member, and a plurality of terminals. The base frame is made of an insulated material. The cover member is made of electrically conductive material and is mounted onto the base frame, whereby a card chamber is formed between the cover member and the base frame. The terminals are mounted onto the base frame, extending into the card chamber. Among the terminals, a detectable terminal is insert-molded in the base frame and located at one side of the base frame. The detectable terminal includes a contact portion exposed outside. The cover member includes a tongue extending toward the detectable terminal therefrom.

20100297886 | Card connector capable of detecting card entry - A card connector is composed of a base, a cover, and a terminal set. The cover is made of a metal and covered onto the base in such a way that an entrance is formed at front sides of the base and the cover and a card space is formed between the base and the cover. The terminal set includes a plurality of terminals mounted to the base. One of the base and the cover includes a working spring strip located at one side of the card connector and the other includes a passive spring strip located at the same side of the card connector as the working spring strip. The working spring strip has a working portion interfering with the card space. When a card enters the card space, the card works on the working portion to force the working spring strip to contact the passive spring strip for perfect electric conduction. | 11-25-2010 |
20110045703 | Card connector capable of scraping - A card connector composed of a base frame, at least one terminal set, and a detective terminal. While a card enters a card space inside of the base frame, it works on and forces a working portion of a working springy piece of the detective terminal toward a passive springy piece of the detective terminal for electric conduction with the same. When the working springy piece is moved to contact the passive springy piece, a scraping portion of the working springy piece contacts and scraps a contact portion of the passive springy piece to force the passive springy piece to deform; meanwhile, the resilience generated by the deformation of the passive springy piece keeps it in contact with the working springy piece. In this way, during the contact, the oxide or stain can be scraped off f to make the contact more perfect to secure the detective accuracy. | 02-24-2011 |
