Abstract: An electrical connector (1) for insertion of an electronic card comprises an insulating housing (10), a plurality of contacts (20) secured to the housing, a shield (30) enclosing a top surface (10a) of the housing and a pair of grounding plates (40) assembled to the housing. The housing defines a receiving slot (18) and a locking slot (19) at the top surface. The grounding plates comprise base portions (42), mating portions (44) extending from bottom edges of the base portions for being soldered to a motherboard, and locking portions (46) extending from top edges of the base portions. The locking portion include hooks (46b) at free ends thereof retained within the locking slots and necks (46a) between the hooks and the base portions for pressing the top surface of the housing, thereby preventing disengagement between the housing and the grounding plate.

Abstract: A card connector (2) comprises a header connector (20), two arms (21) extending forwardly from lateral edges of the header connector and a reinforcing beam (22) being integral with the arms. Each of the arms defines a guiding groove (210) and an upper flange (211) above the groove. The reinforcing beam is configured to have a front edge (221) with a flat middle portion (222) and two side portions (223) beside the middle portion. The side portions incline forwardly and sidewardly from the middle portion toward the guiding arms to connect with the upper flanges of the guiding arms, respectively. The reinforcing beam has a thickness smaller than that of the upper flange.

Abstract: An electrical card connector includes an upper insulative housing (20), a number of upper electrical terminals (22), an upper dielectric transitional element (4), a lower insulative housing (30) stacked below the upper insulative housing, a number of lower electrical terminals (32) and a lower dielectric transitional element (5). The upper electrical terminals are partially retained by the upper insulative housing and are partially received in the upper and lower dielectric transitional elements. The lower electrical terminals are partially received in the lower dielectric transitional element. A pair of elongated plates (6) are embedded in the lower dielectric transitional element.

Abstract: An electrical card connector (1) in accordance with the present invention comprises an insulative housing (10), a plurality of terminals (20) received in the insulative housing, a shield (30) covering the insulative housing, a metal ear (40) connecting with the shield and an ejector 50 fixed on both sides of the shield. The metal ear assembled to the housing comprises a body (41), an engaging section (44) and a buckle section (42) extending respectively from the two sides of the body. The engaging section is adapted to soldering onto the printed circuit board (PCB) (6) and then ground the interferential signals on the metal ear onto the PCB. While the buckle section is locking on the top face (10a) of the housing so that the metal ear can be assembled to the housing firmly when the electrical card connector subjects to the external force in the opposite direction of the PCB vertically upwards.

Abstract: A card connector assembly 1 for connecting a card to a mother board 7 comprises a card connector 2, a spacer 3 defining a plurality of through holes 33 and a daughter board 4 defining a plurality of conductive holes 43. A plurality of terminals 23 received in a plurality of passageways defined in the card connector 2 are inserted into the conductive holes 43 of the daughter card 4 via the through holes 33 of the spacer 3. The spacer 3 forms a pair of hooks 30 to latch with a pair of protrusions 210 of the card connector 2 and a pair of studs 34 to mate with a pair of recesses 44 of the daughter board 4. The spacer 3 further forms two downwardly extending legs 35 which fit into two cutouts 55 in two corners of a socket connector 5 mounted on a mother board 6 when the daughter board 4 is inserted into the socket connector 5.

Abstract: An insulative housing of a PCMCIA card connector includes a header defining a plurality of passageways therein. The passageways are exposed to a rear face of the header for allowing contact elements to be inserted therein from the rear face. The header has a top face forming a post and an opposite bottom face defining a corresponding bore. The post pivotally supports a rocking arm of a card ejection mechanism for releasing a PCMCIA card from the connector. A number of insulative housings may be vertically stacked and precisely positioned with respect to each other by inserting the post of a lower housing into the bore of an upper housing thereby aligning the passageways of the housings. Contact elements fixed to a carrier strip and equally spaced therealong are simultaneously inserted into the passageways of the housings thereby enhancing the efficiency of assembling the PCMCIA card connectors.

Abstract: A card connector comprises a U-shaped insulative housing including an elongate base and a pair of arms, a number of contacts received in the housing and an elongate modular card ejection device. The modular card ejection device comprises a main body and an engaging portion having a T-shaped cross section provided on a side of the main body. Each arm forms a receiving space having a T-shaped cross section in a side face thereof. The receiving space further defines a recess in a middle position thereof. The engaging portion forms an elongate projection outwardly extending from an end thereof. The engaging portion engages with the receiving space and the projection is received in the recess thereby retaining the modular card ejection device on one arm of the housing.

Abstract: An electrical card connector includes a main body having a pair of arms and a grounding plate attached to each arm. Each arm defines a channel in an inner face thereof for receiving an electrical card and at least one connecting portion respectively on a top surface and a bottom surface thereof. The grounding plate has at least an attaching portion for mating with the corresponding connecting portion of the body, and a tail for contacting the electrical card to facilitate electromagnetic discharge of the card.

Abstract: An IC card connector includes an insulative housing and two arrays of terminals retained therein. The housing has a mating face and an opposite mounting face. A space is defined adjacent to the mating face for receiving an IC card therein. An elongate spacer extends from the mounting face and defines a number of notches having different predetermined depths. Each terminal forms a mating portion and an opposite mounting portion. The mating portion extends beyond the mating face and into the space for engaging an IC card. The mounting portion forms a solder end which is secured in the notch and soldered to a circuit board using surface mount technology. All the terminals in one array are dimensioned the same. When the mounting portions of the terminals are secured in the notches, the mating portions therefore extend different predetermined lengths beyond the mating face.

Abstract: An electronic card connector includes a header having two opposite guide arms for receiving an electronic card therein. Contact elements are retained in the header and are electrically engageable with the electronic card. The header forms two pivot pins. A rocking member defines two holes alternately receiving the pivot pins therein for selectively forming a pivotal joint between either one of the pivot pins and the corresponding hole. Each guide arm defines a slide channel formed by two inwardly extending flanges. An elongate slot is defined in the slide channel. A card release bar has at least a projection forming two outwardly extending flanges selectively received in the slide channel of either one of the guide arms and guidingly engaged with the inwardly extending flanges thereof. The projection of the card release bar has a resilient extension forming a barb thereon.
