Abstract
A subscriber identity module (SIM) card connector (1) includes an insulating base (10), a plurality of contact elements (20) partially received in the base, and a one-piece switch member (30) partially received in a channel (13) defined in a top surface (12) of the base. The switch member has upper and lower contact branches (34, 35) extendingrearwardly beyond a rear face of the base. The upper contact branch has an upper contact portion (340) projecting upwardly beyond the top surface of the base. The lower contact branches have lower contact portions (350) projecting downwardly in proximity to a printed circuit board (PCB).
Claims7
A card connector for connecting a card with a printed circuit board (PCB), comprising:
- a rectangular insulating base defining a channel in a top surface thereof;
- a plurality of contact elements received in the base;
- and
- a one-piece switch member having a mounting portion retained in said channel, a solder tail adapted for being soldered to the PCB, a switch contact projecting beyond a rear face of the base, and a horizontal cantilever beam between the mounting portion and the switch contact, the switch contact defining a longitudinal center line and including upper and lower contact portions respectively symmetric about a vertical plane containing the center line, the upper contact portion, upon full insertion of a card, being depressed to move the lower contact portion toward the PCB;
- and
- wherein the lower contact portion has a pair of lower contact branches, and the upper contact portion has an upper contact branch between the lower contact branches.
A card connector assembly comprising:
- a printed circuit board including a solder trace and a switch trace thereon;
- a card connector mounted on the printed circuit board, said connector including an insulative housing with a plurality of contact elements therein and with a top surface thereon;
- a one-piece switch member positioned in the housing, said switch member soldered on said solder trace and including a resilient beam with upper and lower contact portions around an end thereof;
- a card adapted to be mounted on said top surface;
- wherein when no card is positioned upon the top surface, the upper contact portion projects above the top surface and the lower contact portion projects over the switch trace, while when the card is positioned on the top surface, the upper contact portion is pressed downwardly by the card, and the lower contact portion is associatively moved downwardly to abut against the switch trace with mechanical and electrical connections therebetween and
- wherein the lower contact portion has a pair of lower contact branches, and the upper contact portion has an upper contact branch between the lower contact branches.
A card connector comprising:
- an insulative housing with a plurality of contacts therein and with opposite top and bottom faces thereon, said contacts extending upwardly above the top face and also downwardly to reach the bottom face;
- a one-piece switch member positioned in the housing with a solder portion at one end, said switch member further including a resilient beam with upper and lower contact portions around a distal end thereof;
- wherein said upper contact portion upwardly extends above the top face, and the lower contact portion extends above the bottom face while is adapted to extend downwardly beyond the bottom face when the upper contact portion is downwardly pressed by a card which is installed on the top face of the housing;
- and
- wherein the lower contact portion has a pair of lower contact branches, and the upper contact portion has an upper contact branch between the lower contact branches.
