Abstract: A male connector section is held on a female connector section by the engagement of nibs in the metallic holding fixture with projections of the metallic holding fixture in the female connector section.

Abstract: A card connector of the present invention includes: a housing; a card insertion opening formed by opening at least one end of the housing; and a plurality of contacts arranged in the housing; wherein switching mechanism constructed of at least actuator members and a shutter member is provided in the housing. This construction allows a plurality of kinds of cards of different sizes in thickness and width to be used on one and the same card connector without requiring the cards to have any additional member, by performing a switching operation on such members as shutter, actuators and latch arms. This construction can make a distinction between appropriate and inappropriate cards for use on the card connector by permitting the insertion of appropriate cards and blocking the insertion of inappropriate cards.

Abstract: A silicone rubber composition comprising (A) 100 parts by weight of an organopolysiloxane having a degree of polymerization of 100 or higher and having at least two silicon-bonded alkenyl groups in the molecule; (B) from 3 to 100 parts by weight of a wet silica having the following properties: specific surface area (the BET method) of 50 m2/g or larger, specific surface area (the BET method)/specific surface area (the CTAB method) of from 1.0 to 1.3, and water content of 4% or lower; and (C) an effective amount of a curing agent. The silicone rubber composition can be obtained without foaming even in hot air vulcanization and even if wet silica is used therein, and the silicone rubber composition gives a silicone rubber excellent in electrical properties such as electrical insulating properties.

Abstract: Contact terminals, each having a contact pad section and a card-connecting end portion, are arranged in a connecting end unit portion.

Abstract: In a card connector having a push-push type eject mechanism, a cam lever is retained by a cam lever retaining member made from a cantilevered leaf spring, which in turn is retained by a leaf spring formed in a metal cover. The metal cover along with the housing forms a card accommodating portion. The cam lever is therefore doubly retained by the cam lever retaining member and the leaf spring and thus prevented against coming off. This arrangement also enhances a clicking feel of the eject mechanism during the insertion and ejection of the card.

Abstract: A contact terminal includes a card connecting section for electrically connecting with a contact pad of the elongate type memory card while being in contact with the contact pad, a cable connecting section for electrically connecting with the electrode pad of the flexible flat cable while pinching the electrode pad, and a fixing section for coupling the card connecting section with the cable connecting section.

Abstract: A method for soldering parts mounted on a print circuit baseboard with Pb-free material. A reflow soldering process is performed to parts mounted on one side surface of the print circuit baseboard. A flow soldering process is then performed to parts mounted on the other side surface of the print circuit baseboard with a jet flow solder process. Either a composition or a melting point of alloys generated when the reflow and flow soldering are performed is differentiated so that the alloy on one side surface does not melt during a flow soldering process to the other side surface.

Abstract: A card connector that reliably holds an inserted card with a compact mechanism to prevent the falling of the card due to unexpected external forces. The card 10 is formed with the recess 18 to receive the locking portion. The elastic locking piece 50 is mounted to the eject member 41 that slides together with the card 10 as the card is inserted or retracted. The locking piece guide means 50b, 61 converts the motion of the eject member 41 in the card insertion/retraction direction into the motion of the locking portion 50c of the elastic locking piece 50 toward or away from the card so that the locking portion 50c is engaged in the recess 18 during the card insertion and, during the card ejection, is disengaged from the recess 18.

Abstract: A present invention provides a printed board connector, a contact thereof and a mating instrument that prevent deterioration of electrical conductivity and spring property of contacts resulting from solder rising and/or flux rising. A printed board connector can be mounted in a printed circuit board and constitutes a mating instrument in connection with a male connector such as an insulation displacement plug. The connector has a housing and a contact arranged in the housing. The contact includes a pair of forks opposing each other, terminals capable of being soldered to the printed circuit board, and a spacer connecting terminals and the pair of forks together. The spacer provides a predetermined distance between terminals and the pair of the forks to prevent solder and/flux from rising to the forks.
