Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
An electrical connector comprising: a housing; a card receiving mouth in the housing; electrical contacts carried by the housing in the mouth; guide arms on opposite sides of the mouth; a card receiving groove on each of the guide arms; a grounding contact in each groove, each grounding contact comprising; a resilient spring finger projecting in the card receiving groove of a guide arm to engage a card inserted along the card receiving groove, a base providing a solder connection to a circuit board, a finger, an arm between the base and the finger, and the finger and the arm clasping the guide arm to provide a secure connection of the grounding contact to the guide arm.
Claim 2
Dependent Claim
117 words
An electrical connector comprising: a housing; a card receiving mouth in the housing; electrical contacts carried by the housing in the mouth; guide arms on opposite sides of the mouth; a card receiving groove on each of the guide arms; a grounding contact in each groove, each grounding contact comprising; a resilient spring finger projecting in the card receiving groove of a guide arm to engage a card inserted along the card receiving groove, a base providing a solder connection to a circuit board, a finger, an arm between the base and the finger, and the finger and the arm clasping the guide arm to provide a secure connection of the grounding contact to the guide arm.
Claim 3
Dependent Claim
65 words
An electrical connector as recited in claim 1, further comprising: a bight formed by the finger, the bight being wrapped around an end of the guide arm and providing a cantilever support for the resilient finger enabling deflection of the resilient finger in a plane parallel to a plane of the base and parallel to a plane of a solder connection to a circuit board.
Claim 4
Dependent Claim
18 words
An electrical connector as recited in claim 1, further comprising: a bend separating the base from the arm.
Claim 5
Dependent Claim
140 words
An electrical connector comprising: a housing; a card receiving mouth in the housing; electrical contacts carried by the housing in the card receiving mouth; guide arms on opposite sides of the card receiving mouth; a card receiving groove on each of the guide arms; a grounding contact at an end of each of the guide arms, each grounding contact comprising: a base providing a solder connection to a circuit board, a finger, a resilient spring finger extending from the finger and projecting in the card receiving groove of a guide arm to engage a card inserted along the card receiving groove, the finger being wrapped around said end of the guide arm; and a mouth at said end of the guide arm for receiving a card to be engaged by the ground contact at said end of the guide arm.
Claim 6
Dependent Claim
140 words
An electrical connector comprising: a housing; a card receiving mouth in the housing; electrical contacts carried by the housing in the card receiving mouth; guide arms on opposite sides of the card receiving mouth; a card receiving groove on each of the guide arms; a grounding contact at an end of each of the guide arms, each grounding contact comprising: a base providing a solder connection to a circuit board, a finger, a resilient spring finger extending from the finger and projecting in the card receiving groove of a guide arm to engage a card inserted along the card receiving groove, the finger being wrapped around said end of the guide arm; and a mouth at said end of the guide arm for receiving a card to be engaged by the ground contact at said end of the guide arm.
Claim 7
Dependent Claim
68 words
An electrical connector as recited in claim 4, and further comprising: a bend separating the base from the arm, a bight formed by the finger, the bight being wrapped around said end of the guide arm, the bight being formed by said finger and providing a cantilever support for the resilient finger enabling deflection of the resilient finger in a plane parallel to a plane of the base.
Claim 8
Dependent Claim
76 words
An electrical connector as recited in claim 4, and further comprising: a bight engaging said end of the guide arm, the bight being formed by said finger wrapped around the end of the guide arm and providing a cantilever support for the resilient finger enabling deflection of the resilient finger in a plane parallel to a plane of the base and parallel to a plane of a solder connection of the base to a circuit board.
Claim 9
Dependent Claim
18 words
An electrical connector as recited in claim 6, further comprising: a bend separating the base from the arm.
