Abstract: An electrical terminal has a soldering plate having a front end soldered onto a printed circuit board and a rear end edge bent upward to raise beyond a plane of the soldering plate, an elastic plate extending rearward from a substantial middle of the rear end edge of the soldering plate and inclined upward, a contact portion protruding rearward from a distal end of the elastic plate, and two strengthening arms extending rearward from two ends of the rear end edge of the soldering plate. The strengthening arms are inclined downward and towards the printed circuit board in process of extending rearward, so as to make distal ends thereof resist against the printed circuit board to strengthen the restoring elasticity of the elastic plate, when an external force presses the contact portion and the elastic plate downward.

Abstract: A card connector for receiving a card includes an insulating housing, a plurality of conductive terminals received in the insulating housing, a first switch terminal, a second switch terminal and a shielding shell covered on the insulating housing. The insulating housing defines a first switch groove, a second switch groove, a first fastening groove and a second fastening groove. The first switch terminal includes a first fastening portion fastened in the first fastening groove, a first locating portion located in the first switch groove, and a first contact portion hung over the insulating housing. The second switch terminal includes a second fastening portion fastened in the second fastening groove, a second locating portion located in the second switch groove, and a second contact portion hung over the insulating housing to electrically contact with the first contact portion under the pressure of the card.

Abstract: A card connector includes an insulating housing defining a first receiving chamber and a second receiving chamber. A fool-proofing member has a pivot pillar vertically pivoted in one side of the insulating housing, a first fool-proofing portion and a second fool-proofing portion protruded on an outside face of the pivot pillar and apart designed at an upper position and a lower position of the pivot pillar at an angle. An elastic element is put around a top of the pivot pillar to make the first fool-proofing portion hidden in the insulating housing and the second fool-proofing portion stretched in the second receiving chamber for receiving one card in the first receiving chamber. The first fool-proofing portion stretches into the first receiving chamber under the rotation drive of the fool-proofing member realized by another card being inserted into the second receiving chamber to push the second fool-proofing portion rearward.

Abstract: A connector terminal is assembled in an insulating housing defining a receiving cavity of which front and rear sides protrude face-to-face to form two blocking eaves. The connector terminal has a fastening strip of which a bottom edge protrudes downward to form two elastic arms spaced from each other, and a soldering portion between the two elastic arms. The elastic arms are apart from two opposite side edges of the soldering portion to define two receiving intervals between the soldering portion and the elastic arms. Distal ends of the elastic arms oppositely protrude to form two fastening barbs. The soldering portion and the elastic arms are inserted in the receiving cavity. The fastening barbs slide through the blocking eaves to be hooked under the blocking eaves respectively and the fastening barbs can be avoided scraping the connector by means of cushion effects of the receiving intervals.

Abstract: A card connector includes an insulating housing, a shell covering on the insulating housing to define a card receiving space between the cover and the insulating housing for being inserted into a card along an insertion direction, a plurality of contacts received in the insulating housing and extended into the card receiving space, a first switch terminal and a second switch respectively positioned at a right side of the insulating housing. The first switch terminal includes a main section extended along the insertion direction, a first straight section and a second straight section successively and slantwise extended into the card receiving space form a free end of the first main section to respectively define a first slope and a second slope relative to the main section. The second switch terminal includes a contacting section extending beside the first straight section. The second slope is larger than the first slope.
