Smart card connector with card biasing means

Claim 2

A connector for use with a smart card, the connector comprising: an insulative housing comprising a base and a cover, the base and the cover defining a card slot between the base and the cover, the card slot being open at an entrance at a front of the housing and extending toward a rear of the housing, with the housing base and the cover having a shroud formed by converging inclined surfaces thereon at the car slot entrance; data contacts extending into the slot, full insertion of the smart card into the card slot resulting in engagement of the data contacts with the smart card; and a pair of cantilever beams integrally molded from the housing base extending along the card slot and including projecting portions adjacent distal ends thereof protruding into the card slot along both sides of the data contacts, and between the data contacts and the entrance to the card slot so that a card inserted into the card slot is diverted away from the data contacts during card insertion to reduce wear on the data contacts.

Claim 3

The connector of claim 1 wherein each cantilever beam includes bosses adjacent the cantilever beam distal end, only the bosses protruding into the card slot.

Claim 4

The connector of claim 1 wherein each cantilever beam joins the housing base adjacent the front of the card slot with the bosses located at the rear of the cantilever beams.

Claim 5

The connector of claim 1 wherein the card entry shroud comprises converging inclined surfaces on the housing base and the cover.

Claim 6

The connector of claim 1 wherein the housing base includes openings communicating with the card slot to provide clearance for the deflection of data contacts, the openings being located between said cantilever beams.

Claim 7

A connector for use with a smart card, the connector comprising: an insulative housing comprising a base and a cover, the base and the cover defining a card slot between the base and the cover, the card slot being open at an entrance at a front of the housing and extending toward the rear of the housing, with the housing base and the cover having a shroud formed by converging inclined surfaces thereon at the card slot entrance; data contacts extending into the slot, full insertion of the smart card into the card slot resulting in engagement of the data contacts with the smart card; a switch located at the rear of the card slot, the switch being activated when a smart card, fully inserted into the card slot engages the switch; and a pair of cantilever beams integrally molded from said housing base and including projecting portions adjacent distal ends thereof extending into the card slot along both sides of the data contacts proximate the card slot entrance to bias the smart card away from the data contacts during initial stages of insertion of the smart card into the card slot.

Claim 8

A connector for use with a smart card, the connector comprising: an insulative housing comprising a base and a cover, the base and the cover defining a card slot between the base and the cover, the card slot being open at an entrance at a front of the housing and extending toward the rear of the housing, with the housing base and the cover having a shroud formed by converging inclined surfaces thereon at the card slot entrance; data contacts extending into the slot, full insertion of the smart card into the card slot resulting in engagement of the data contacts with the smart card; a switch located at the rear of the card slot, the switch being activated when a smart card, fully inserted into the card slot engages the switch; and a pair of cantilever beams integrally molded from said housing base and including projecting portions adjacent distal ends thereof extending into the card slot along both sides of the data contacts proximate the card slot entrance to bias the smart card away from the data contacts during initial stages of insertion of the smart card into the card slot.

Claim 9

The connector of claim 6 wherein the switch comprises a deflectable spring, the deflectable spring being positioned for engagement with a smart card fully inserted into the card slot, the cantilever beams exerting a force on the smart card to resist a restoring force exerted by the deflectable spring.

Claim 10

The connector of claim 7 wherein the switch includes both a spring and a stationary post, both the spring and the post being mounted in the base, so that the connector can be mounted on a printed circuit board with the switch and post connected to a circuit for determining when a card is present in the connector.

Claim 11

The connector of claim 6 wherein the housing base includes a card stop at the rear of the card slot, each cantilever beam being positioned in front of the card stop.

Claim 12

A connector for use with a smart card, the connector comprising: an insulative housing comprising a base and a cover, the base and the cover defining a card slot between the base and the cover, the card slot being open at an entrance at a front of the housing and extending toward the rear of the housing, with the housing base and the cover having a shroud formed by converging inclined surfaces thereon at the card slot entrance; data contacts extending into the card slot, full insertion of the smart card into the card slot resulting in engagement of the data contacts with the smart card; a pair of cantilever beams having projecting portions at distal ends thereof protruding into the card slot between the data contacts and the entrance to the card slot so that a card inserted into the card slot is biased upwardly in the card slot prior to engaging the data contacts, each of said cantilever beams being molded integrally with the housing base adjacent opposite sides of the card slot with said data contacts therebetween, with the housing base having gaps extending therethrough along both sides and the distal end of of each of said cantilever beams.

Claim 13

A connector for use with a smart card, the connector comprising: an insulative housing comprising a base and a cover, the base and the cover defining a card slot between the base and the cover, the card slot being open at an entrance at a front of the housing and extending toward the rear of the housing, with the housing base and the cover having a shroud formed by converging inclined surfaces thereon at the card slot entrance; data contacts extending into the card slot, full insertion of the smart card into the card slot resulting in engagement of the data contacts with the smart card; a pair of cantilever beams having projecting portions at distal ends thereof protruding into the card slot between the data contacts and the entrance to the card slot so that a card inserted into the card slot is biased upwardly in the card slot prior to engaging the data contacts, each of said cantilever beams being molded integrally with the housing base adjacent opposite sides of the card slot with said data contacts therebetween, with the housing base having gaps extending therethrough along both sides and the distal end of of each of said cantilever beams.

Claim 14

The connector of claim 10 wherein the lower surface of the card slot is defined by a recessed surface into the top of the housing base.

Claim 15

The connector of claim 11 wherein openings extend through said recessed surface into the housing base to provide clearance for deflection of the data contacts.

Claim 16

The connector of claim 12 wherein the housing base includes a channel at the rear of the housing base, the channel communicating with the card slot, at least some of the data contacts extending from the channel into the card slot.

Claim 17

The connector of claim 13 wherein mounting posts extend from a lower surface at a periphery of the housing base for mounting the connector to a printed circuit board.
