Patent application numberDescriptionPublished
20090142948Memory card connector with improved contact arrangement - A USB card connector includes an insulative housing and a plurality of contacts retained in the insulative housing. The insulative housing includes a rear wall and a card receiving cavity located forward the rear wall. Each contact includes a contact portion protruding to the card receiving cavity. The contacts are divided into first and second contact groups with same contact arrangement in condition that each the first or the second contact group comprises four contacts for transmitting USB or similar-USB signals.06-04-2009
20090149047Memory card connector with improved switch contacts for stably detection of card insertion or removal - A memory card connector includes an insulative housing and a plurality of contacts retained in the insulative housing and a pair of switch contacts. The insulative housing defines a card receiving cavity for receiving a memory card. The pair of switch contacts are of a first status when the memory card is located in a deepest insertion position of the card receiving cavity, and the pair of switch contacts are of a second status different from the first status when the memory card is located in a final working position.06-11-2009
20090149071Electrical card connector with improved card restriction structure - An electrical card connector for insertion of a first card and a second card which is wider than the first card, includes an insulative housing defining a front mating port, a card receiving space extending backwardly from the mating port for receiving the first and the second cards, and a plurality of terminals for mating with a first card and a second card wider than the first card. A card restriction mechanism is fixed to the insulative housing and includes a guiding body and an elastic spring located on the guiding body. The guiding body restricts and guides the first card and second cards to be inserted into the receiving space while the cards moving through the mating port.06-11-2009
20090221168Memory card connector with improved sliding structure to reduce friction - A memory card connector includes an insulative housing, a plurality of contacts retained in the insulative housing, a card eject mechanism and metal shell attached to the insulative housing. The insulative housing defines a card receiving cavity for insertion of a memory card. The card eject mechanism includes a slider moveable along card-insertion or card-withdraw directions and a locking member fixed to the slider. The locking member includes a protrusion which forms a sideward dimple. The metal shell includes a top wall covering the card receiving cavity. The top wall defines a slit for receiving the protrusion. An arced surface of the dimple is driven to abut against an inner side of the slit in order to reduce friction therebetween.09-03-2009
20090246993Push-push card connector - A card connector (10-01-2009
20090253280Electrical card connector having an improved insulative housing - An electrical card connector (10-08-2009
20100087074ELECTRONIC CARD CONNECTOR WITH A LIMITING WALL FOR LIMITING AN ELECTRONIC CARD OBLIQUELY INSERTED THEREIN - An electronic card connector (04-08-2010
20100184335ELECTRONIC CARD CONNECTOR - A card connector for connecting a memory card with asymmetric side edges comprises an insulative housing having a recess for receiving the memory card. The insulative housing has an inlet in the front end of the recess for inserting the memory card, and a pair of arms in two sides of the recess. The pair of arms are asymmetric and corresponding to the side edges of the memory card, so that the card connector can block card like SD card inserted into the recess.07-22-2010
20100227489Electrical card connector - An electrical card connector defines a receiving space for receiving an electrical card, and includes an insulative housing and an ejecting mechanism retained in the insulative housing. The ejecting mechanism includes a slider, a coil spring for driving the slider moving along an insertion direction of the electrical card, and a latch spring secured on the slider and extending into the receiving space for pressing on the electrical card. The electrical card connector further includes a limiting portion abutting against the latch spring to increase a lock force on the electrical card, thus the electrical card would be prevented from flying out of the electrical card connector.09-09-2010
20100267260CARD CONNECTOR HAVING AN IMPROVED SPRING MEMBER - A card connector (10-21-2010
20110034050ELECTRONIC CARD CONNECTOR WITH A RELEASING PORTION FOR INSERTING OR EJECTING AN ELECTRONIC CARD SMOOTHLY - An electronic card connector defining a receiving space for receiving an electronic card, includes an insulative housing, a number of contacts retain in the insulative housing, and a metal shell covering the insulative housing. The insulative housing has a bottom wall. The metal shell has a top wall opposed to the bottom wall, and a pair of side walls. The metal shell defines a depressed portion outwardly recessed from an intersection portion of the top wall and the side wall.02-10-2011
20110053396ELECTRONIC CARD CONNECTOR WITH AN IMPROVED HOUSING FOR ASSEMBLING A SWITCH TERMINAL THEREOF FAVORABLY - An electronic card connector includes an insulative housing, a number of contacts and a first switch terminal retained on the insulative housing. The insulative housing has a receiving space, a receiving slot communicating with the receiving space along an up to down direction and a limiting block at a front side of the receiving slot. The first switch terminal has a fastening portion retained on the insulative housing, a connecting portion forwardly extending to the receiving slot, a limiting portion forwardly extending to a lower side of the limiting block and a tail portion. The switch terminal further has a guiding portion extending sidewardly. The insulative housing has a pre-pressing surface at one side of the receiving slot to pre-press the guiding portion and prevent the switch terminal from bouncing upwardly to resist a front side of the limiting block in an assembly process of the switch terminal.03-03-2011
20110111635CARD CONNECTOR HAVING AN IMPROVED SPRING ARM - A card connector includes a first inserting slot (05-12-2011
