Abstract

Abstract A card connector includes a detecting unit indicating the full insertion of a card into a card-receiving slot that provides no pressure on the card in the direction of its ejection, thereby providing for better reliability of electrical connections between the connector and the card. Card (C) is inserted in card-receiving slot (4) of housing (2) of card connector (1). When the card (C) is fully inserted in the card-receiving slot, one side of the card presses down V-shaped contact section (52a) of sensing member (52) breaking its electrical contact with sensing member (54), thus confirming the full insertion of the card into the card-receiving slot. The V-shaped contact section (52a) exerts pressure against the card (C) in a perpendicular direction.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 163 words
A card connector, comprising a housing having a card-receiving slot for receiving a card therein; electrical contacts in the housing including contact members extending into the card-receiving slot for electrical engagement with the card; a detecting unit in the housing including sensing members mounted side-by-side in the housing; one of the sensing members having a contact portion that is spaced below the card-receiving slot; and another of the sensing members including a base section having a front end and a rear end, a spring-loaded arm that extends upwardly from the rear end and forwardly beyond the front end of the base section, the spring-loaded arm including an arcuate section that extends into the card-receiving slot, and a connecting section that extends under the contact portion and is normally engaged with the contact portion, whereby when the card is received in the card-receiving slot, the card engages the arcuate section and deflects the spring-loaded arm, thereby disengaging the connecting section from the contact portion.
Claim 2
Dependent Claim 163 words
A card connector, comprising a housing having a card-receiving slot for receiving a card therein; electrical contacts in the housing including contact members extending into the card-receiving slot for electrical engagement with the card; a detecting unit in the housing including sensing members mounted side-by-side in the housing; one of the sensing members having a contact portion that is spaced below the card-receiving slot; and another of the sensing members including a base section having a front end and a rear end, a spring-loaded arm that extends upwardly from the rear end and forwardly beyond the front end of the base section, the spring-loaded arm including an arcuate section that extends into the card-receiving slot, and a connecting section that extends under the contact portion and is normally engaged with the contact portion, whereby when the card is received in the card-receiving slot, the card engages the arcuate section and deflects the spring-loaded arm, thereby disengaging the connecting section from the contact portion.
Claim 3
Dependent Claim 32 words
The card connector according to claim 1, wherein the spring-loaded arm includes a flat section that is forward of the arcuate section, and the connecting section extends sidewise from the flat section.
Claim 4
Dependent Claim 172 words
A card connector, comprising a housing having a card-receiving slot for receiving a card therein; electrical contacts in the housing including contact members extending into the card-receiving slot for electrical engagement with the card; a detecting unit in the housing including sensing members mounted side-by-side in the housing; one of the sensing members having a contact portion that is spaced below the card-receiving slot; and another of the sensing members including a base section and a spring-loaded arm that extends upwardly and forwardly from a rear end of the base section, the spring-loaded arm having an arcuate section that extends into the card-receiving slot, a flat section that is forward of the arcuate section, and a connecting section that extends sidewise from the flat section to a position under the contact portion, the connecting section being normally engaged with the contact portion, whereby when the card is received in the card-receiving slot, the card engages the arcuate section and deflects the spring-loaded arm, thereby disengaging the connecting section from the contact portion.
Claim 5
Dependent Claim 172 words
A card connector, comprising a housing having a card-receiving slot for receiving a card therein; electrical contacts in the housing including contact members extending into the card-receiving slot for electrical engagement with the card; a detecting unit in the housing including sensing members mounted side-by-side in the housing; one of the sensing members having a contact portion that is spaced below the card-receiving slot; and another of the sensing members including a base section and a spring-loaded arm that extends upwardly and forwardly from a rear end of the base section, the spring-loaded arm having an arcuate section that extends into the card-receiving slot, a flat section that is forward of the arcuate section, and a connecting section that extends sidewise from the flat section to a position under the contact portion, the connecting section being normally engaged with the contact portion, whereby when the card is received in the card-receiving slot, the card engages the arcuate section and deflects the spring-loaded arm, thereby disengaging the connecting section from the contact portion.
Claim 6
Dependent Claim 28 words
The card connector according to claim 3, wherein the base includes a front end, and the spring-loaded arm extends forwardly beyond the front end of the base section.
