A smart card reader 10 is disclosed having a base 12 which is profiled to have a card receiving area 20. Contacts 22,23 are disposed inside a contact receiving 32 of the base and are pivotable about a leg 40. Insertion of a smart card 60 causes the contacts 22,23 to pivot about the pivot point 42 in order to cause contact points 50 to engage contact pads of the smart card 60.

A connector (10) for interconnecting circuitry (12, 16) of two circuit boards (14, 18) which carry relatively high frequency signals, includes a receptacle connector (20) and a mating plug connector (24). The receptacle connector (20) includes shield plates (56) between each adjacent pair of signal contacts (58) and the mating plug connector (24) includes a central elongated ground plate (136) that electrically engages each of the shield plates (56). The ground plate (136) includes a plurality of leads (142) along its length that engage ground pads on the circuit board (18). The plug connector (24) includes an outer shield (146) that substantially surrounds the plug connector (24) and includes leads (148) that are attached to the leads (142) of the elongated ground plate (136).

A multicontact electrical connector comprises an insulating housing having a substrate-receiving face. A trough-like opening extends into the face for reception of a substrate. In the housing are spaced-apart terminals having free ends which are proximate to the substrate-receiving face and fixed ends which are proximate to an inner end of the opening. Contact surfaces are on the free ends for contacting spaced-apart terminal pads on the substrate. Contact engagement camming means are provided for flexing the terminals and moving the free ends from the opening allowing the substrate to be placed in the opening under reduced insertion force conditions. As the free ends of the terminals are subsequently moved, the contact surfaces of the free ends will be resiliently biased against the terminal pads. Contact wipe camming means are provided to move the contact surfaces across the terminal pads as normal force occurs permitting a wiping action to take place. A locking means is provided to hold the substrate in place as the wiping action occurs. This assures that the contact surfaces and the terminal pads, where engagement therebetween takes place, are cleaned and a positive electrical connection is effected.

An electrical connector assembly 2 for use in connecting parallel printed circuit boards includes a receptacle connector 4 and a plug connector 6. The receptacle connector 4 includes receptacle contacts 8, each of which includes a surface mount solder tail 16 and a mating contact section in the form of a resilient arm 26 on opposite sides of a sealing pad 18 that seals a contact insertion opening 38 when the receptacle contact 8 is fully inserted. The mating contact portion is therefore isolated from contaminating materials, such as solder flux during surface mount solder operations. The height of the connector assembly 2 can be adjusted by using plug connectors 6 of different heights with a universal receptacle connector 4. The height of the side walls 60 on the plug housing 12, between a plug mating section and contact retention section is changed for different plug connector heights. The length of the plug contact 10 can also changed because the plug contact solder tail 56 is bent into its final position after the plug contacts 10 are mounted on the plug housing 12.

A connector for electrically connecting circuit members having a high density of contact pads located in an area array, the connector having an area array specific holder that is simple to produce for retainably positioning mass-produced standardized contact modules containing a deformable contact within a module body for interconnecting the contact pads, where the contact is constructed to be supportingly engaged by the module body to provide sufficient opposing spring force to effect a wiping interconnection between the contact and the contact pads.

A contact socket having ends and an intermediate portion for receiving a contact pin. The intermediate portion has a plurality of resilient beams which are designed to provide the necessary contact force while maintaining the insertion force at a low level. The beams are also designed to allow for improper insertion of the pin into the contact socket without damaging the resilient beams so that no permanent set of the beams takes place.

Chip carrier socket 2 comprises a socket body 24 having a rectangular base 30 and walls 34 extending normally from the edges 32 of the base. The walls can be pivotally moved inwardly of the recess which is defined by the walls after a chip carrier 12 has been placed in the recess. A frame 28 is provided in surrounding relationship to the walls 34 and is movable relative thereto between a first position and a second position. When the frame 28 is moved to the second position, the walls 34 are moved inwardly thereby to move the contact terminals 26 in the walls against terminal pads 20 on the leadless chip carrier 12. The frame 28 also may have an ejector means integral therewith which will eject the chip carrier from the socket when the frame is moved from a second position to the first position. The frame may also cam the walls outwardly to permit placement of the chip carrier in the recess under ZIF conditions.

An electrical connector 10 having a configurable ground plane 60 is provided. The connector 10 features an insulative housing 20 having an upright section 30 and a board receiving section 28. The board receiving section has open top and bottom outer surfaces 29, 27 for allowing insertion of contacts 50, 52 into contact receiving passages 34, 32. The ground plane 60 is disposed over the top set of contacts 50 and is profiled to engage selected ones of the contacts 50 in the upright section of the passages 34. The ground plane 60 is configurable in that it can be easily adapted to achieve various signal to ground contact ratios by locating contacts 92, 94 at selected positions on fingers 88 which extend into the upright section of the passages 34.
摘要:
An improved contact for use in a high density chip carrier socket mounted on a circuit member which utilizes a cover which to wedge the leads of the chip carrier into electrical engagement with a respective contact. A tool receiving recess is incorporated into the contact so that the forces exerted on the socket while pressing the cover into place can be opposed, minimizing the forces exerted on the connection between the socket and the circuit member, typically a solder joint. Providing a tool, that operates from one side of the circuit member, in order to press the cover into place while engaging the contact recess to oppose the insertion related forces, which can also pull the cover from the contacts, without exerting significant forces on the connection, by engaging a lip in the cover while pressing on the carrier.
