Abstract: A card reading device includes an insulating housing, at least a set of conductive terminals, a rear wall, and a shielding member. The rear wall includes a metal plate and a plastic plate that is formed by insert molding, which has a stable configuration and is unlikely to shake or distortion. The rear wall reliably presses and contacts with a top edge of a soldering portion of the conductive terminals, which is easier to be soldered so as to avoid soldering skipping or solder voiding. Moreover, the shielding member presses a top edge of the rear wall so as to make the rear wall securely press the soldering portion. Furthermore, the rear wall includes a plurality of openings therein, which make the gas circulate so as to avoid solder voiding. Thereby the qualified ration is improved.

Abstract: A foolproof device mounting arrangement of a card connector is disclosed to include a metal baffle set in between a first receiving chamber and a second receiving chamber in a connector body and movable vertically between the first receiving chamber and the second receiving chamber to prevent insertion of a second memory card into the connector body after insertion of a first memory card, and a plurality of springy support members mounted inside the connector body for supporting the metal baffle in between the first receiving chamber and the second receiving chamber.

Abstract: A card reading device includes an insulating housing and at least one set of conductive terminals. The set of conductive terminals are mounted on the insulating housing by a locating member of the insulating housing. The card reading device has a simple configuration. Thereby, it is engaged more easily and production efficiency is improved.

Abstract: A card reader apparatus is additionally provided with a lifting mechanism, thereby protecting the signal terminals which are not in use, yet allowing electrical contact with the signal terminals that are in use. It comprises an insulation housing having a pivotally jointing portion formed in a card insertion space, a plurality of signal terminal sets disposed on the module substrate, and a lifting mechanism including a lifting plate and elastic components. The lifting plate with a receiving space is pivotally attached to the pivotally jointing portions at one end of the lifting plate. The elastic components are arranged between the lifting plate and the insulation housing. One of the signal terminal sets has its respective contact portions corresponding to the receiving space, and the other of the signal terminal sets has its respective tip portions corresponding to the other end of the lifting plate.

Abstract: A card reading apparatus for insertion of an electronic card therein has an insulating housing and a set of control terminals. The insulating housing has an insertion space formed therein. The set of control terminals has a first control terminal and a second control terminal. The first control terminal has a first retaining portion and a first elastic arm. The first elastic arm has a push portion and an elongation portion. The second control terminal has a second retaining portion. A free end of the elongation portion is disposed at a corresponding lateral side of the second retaining portion to form a gap therebetween in a normal status. When the electronic card is inserted into the insertion space, the electronic card pushes the push portion, such that the free end of the elongation portion moves toward the second retaining portion and slidably contacts thereon.

Abstract: A connector interference prevention grounding mechanism comprises a circuit board with a connector on one side. The connector has a plurality of slots, each slot contains a sleeve internally. One metal board each is on top and bottom of the connector. Internal to the side slots on both end of the connector has a grounding sleeve. A C-shaped spring tongue is in the middle of the grounding sleeve. A convex point is on the bottom of the metal board and beneath the C-shaped spring tongue. Therefore by the C-shaped spring tongue of the grounding sleeve contacting the convex point of the metal board, the grounding sleeve also connects to the circuitry of the circuit board so that the electromagnetic wave and static electricity absorbed by the metal board can be conducted to the circuit board through the grounding sleeve to eliminate the electromagnetic wave and static electricity.

Abstract: A pressing bar for connecting legs of connectors includes a connector with a plurality of slots. A sleeve is inside each slot with a connecting leg that is soldered on a connecting point of a circuit board. The connecting legs are further fixed onto the circuit board with a pressing bar. The pressing bar includes a pair of pressing ears on both ends and a plurality of troughs on the bottom. A fastening hole is on both ends of the connector. By placing the pressing ear of the pressing bar into the fastening holes of the connector, the pressing bar is fixed on top of the connector and the troughs of the pressing bar are firmly attached on top of the connecting legs of the sleeves. Thus the connecting legs are pressed on top of the connecting points so as to avoid bad connections and open circuit conditions.
