Abstract:
Connector receptacles that can provide audible feedback to inform a user that a card has been properly inserted, and can include structures to protect contacts in a connector receptacle from damage due to an improper card insertion. An example can provide a connector receptacle having a click module to provide audible feedback indicating that a card has been fully inserted. Another example can provide a connector receptacle having movable contacts that can remain out of an insertion path until the card is at least partially inserted.
Abstract:
Various embodiments include a plug receptacle for an electrical plug-in connection for receiving a plug with electrical plug conductor comprising a contact region for electrical connection to the plug receptacle comprising: a housing with an insertion region into which the plug can be releasably inserted; an electrical plug receptacle conductor rigidly arranged in the housing; and an electrical connecting conductor floating in the housing configured to electrically connect the plug receptacle conductor to the plug conductor. The electrical connecting conductor exerts a connecting force onto the contact region of the plug conductor once inserted into the plug receptacle. The connecting force runs substantially orthogonally in relation to said contact region.
Abstract:
Provided is a contactor that can be manufactured easily and secure a long stroke. A contactor includes: a flexible board; a plurality of contact point portions that are provided in the flexible board; a plurality of springs that urge the contact point portions respectively toward an inspection target device; and a housing that receives the plurality of springs. Each of the springs has a flat winding portion that is provided at least at an end portion of the spring on the contact point portion side, and a diagonal tight winding portion that is provided at a longitudinally intermediate portion of the spring. A gap is present between the flat winding portion and the diagonal tight winding portion in an uncompressed state of the spring.
Abstract:
A direct plug element (2), comprising a plug housing (6), a direct contact (3), which is designed for direct contacting with an exposed contact region (40), wherein the direct contact (3) has a one-piece design, wherein the direct contact (3) is U-shaped and has a contact lamella region (31) and a press-on spring region (32), and wherein a contact point (33) on the contact lamella region (31) is offset in the plugging direction (S) from a press-on point (34) on the press-on spring region (32).
Abstract:
There are two alternatives to a board-to-board connector. One alternative includes a first connector and a second connector. The assembly of the first connector and the second connector is capable of electrically connecting a hard circuit board to another hard circuit board. The other alternative includes the first connector and a cap. The assembly of the cap and the first connector is capable of electrically connecting a flexible circuit board to a hard circuit board.
Abstract:
A connection system for coupling a memory card or other device to a computer system. The connection system utilizes a sliding rack of contacts to provide electrical coupling between the card and the connections system. This sliding rack of contacts is pushed back as a card is inserted and allows the card to be inserted wiht minimal force. The card may then be released by applying a small amount of pressure and then releasing the card. A spring device in the connection system will then force the card out of the connection system to a position where it may be easily removed. The preferred embodiment of the present invention produces an audible and tactile click when the card is properly inserted into the connection system housing. Another audible and tactile click is produced when the card is released. The preferred embodiment also utilizes a flexible circuit for coupling a contact assembly on the sliding rack of connectors to the computer system or other device.
Abstract:
A connector device for electrically connecting an IC card to a reading and/or writing apparatus. A first guide defining a transport path for the IC card is arranged within a casing having an insertion opening for the IC card. The transport path for the IC card extends from the insertion opening. A second guide extends in inclined relation to the transport path. A contact-probe support is guided by the second guide. The contact-probe support has supported thereon a plurality of contact probes projecting toward the first guide and an elastic arrangement biasing the contact probes toward the first guide. An abutment is associated with the contact-probe support and is arranged in crossing relation to the transport path. As a leading edge of the IC card is abutted against the abutment, the contact-probe support moves together with the IC card, away from the insertion opening and, simultaneously therewith, approaches the IC card under guidance of the second guide, to bring the contact probes into contact respectively with contacts on the IC card.
Abstract:
A passive cam follower comprising a bracing means and a compression means is provided for an electrical article (such as an active socket terminal) having spring contact arms, which holds the spring contact arms in a spring biased position for mating with another electrical article (such as a pin terminal) requiring subtantially lessened insertion force. Upon mating the bracing means is urged away from the spring contact arms by the mating article and into a compressed state. Upon withdrawal of the mating article the bracing means is urged forward by the compressed compression means and follows the mating article and resumes its original bracing position relative to the spring contact arms. The bracing means may be a compression spring and have a cap on the forward end and may be a coil spring or an integral molded plastic spring. In a card edge connector a bracing means may be disposed in the card-receiving cavity and comprise an integral molded plastic spring. In an active pin terminal, the passive cam follower may be a coaxially disposed coil compression spring holding together the spring contact arms comprising the pin contact section, and the spring may have a collar on the forward end thereof. Other embodiments are directed toward socket terminals having a single spring contact arm, single-sided card edges connectors having only one row of spring contact arms, and multi-contact pin/socket connectors having sockets each utilizing one spring contact arm.
Abstract:
An electrical connector permits the use of non-noble metals by providing mechanical advantage in obtaining high contact force with low insertion force. A pin is utilized as a cantilever beam to provide high contact force. A carrier, which is activated by insertion by a printed circuit board or the like, includes a lever forming part of the electrical connection. The lever is displaced causing deflection of the pin. The lever has contact points capable of piercing non-metallic oxides, thereby forming good electrical contacts.
Abstract:
A circuit board having metal eyelets in one end thereof that are the terminals of the electrical circuit on the board is mated with a connector that has a plurality of pairs of male members that a re aligned with and pass into the eyelet holes in the circuit board. When the circuit board is inserted into the connector, the male members enter both sides of the holes in the circuit board and, by action of the planar surfaces of the end portions of opposing male members, the male members are forced into pressure contact with the inner wall of the holes thereby completing the electrical circuit between the connector and the circuit board.
