Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
103 words
A set of contact elements for use with a card comprising contact zones, said set comprising: an insulating body (11) having an upper surface (20) and a bottom surface (21), reading contact elements inserted into said insulating body (11) and extending with the contact regions beyond the upper surface (20) of the insulating body (11), and at least one additional contact element (15) located adjacent to one of said reading contact elements so as to form together therewith a card presence switch (40), wherein the additional contact element adapted for cooperation with one of said reading contact elements is a ground contact element.
Claim 2
Dependent Claim
103 words
A set of contact elements for use with a card comprising contact zones, said set comprising: an insulating body (11) having an upper surface (20) and a bottom surface (21), reading contact elements inserted into said insulating body (11) and extending with the contact regions beyond the upper surface (20) of the insulating body (11), and at least one additional contact element (15) located adjacent to one of said reading contact elements so as to form together therewith a card presence switch (40), wherein the additional contact element adapted for cooperation with one of said reading contact elements is a ground contact element.
Claim 3
Dependent Claim
21 words
The set of contact elements of claim 1 wherein the contact regions of said reading contact elements are contact cusps (43).
Claim 4
Dependent Claim
45 words
The set of contact elements of claim 1 wherein said card presence switch (40) is a lagging switch, which is activated only after the contact zones of the card are contacted or engaged by the reading contact elements and one or more ground contact elements.
Claim 5
Dependent Claim
22 words
The set of contact elements of claim 1 wherein the reading contact elements and the ground contact elements are of identical design.
Claim 6
Dependent Claim
37 words
The set of contact elements of claim 1, wherein the ground contact elements is located elevationally lower than the reading contact elements due to the design of the chamber within which said ground contact element is located.
Claim 7
Dependent Claim
37 words
The set of contact elements of claim 1, wherein the ground contact element is located elevationally lower than the reading contact elements due to the design of the chamber within which said ground contact element is located.
Claim 8
Dependent Claim
37 words
The set of contact elements of claim 1 wherein the contact elements forming the card presence switch (40) are adapted to be closed in the direction in which the card is pressed against the reading contact elements.
Claim 9
Dependent Claim
25 words
The set of contact elements of claim 1 wherein said card presence switch is a switch which closes to indicate the presence of a card.
Claim 10
Dependent Claim
28 words
The set of contact elements as set forth in claim 1 wherein said card presence switch is a switch which opens to indicate the presence of a card.
Claim 11
Dependent Claim
34 words
The set of contact elements as set forth in claim 1 wherein said card is in a chip or SIM-card, and wherein the additional contact elements is located below said one reading contact element.
Claim 12
Dependent Claim
96 words
The set of contact elements of claim 10, wherein the ground contact element and/or the additional contact element are provided at least in the contact area, with a corrugation, wherein in the case of a corrugation provided in the ground contact element and a corrugation provided in the additional contact element, said corrugations extend crosswise, and wherein further due said corrugations a higher specific contact pressure is obtained and thus a higher degree of contact safety inasmuch as layers of foreign matter, for example, dust and the like, which might be present, are pierced during contacting.
Claim 13
Dependent Claim
24 words
The set of contact elements of claim 1 wherein said insulating body comprises contact chambers formed therein in which said reading elements are inserted.
Claim 14
Dependent Claim
28 words
The set of contact elements of claim 12 wherein said additional contact element is located in at least one of said contact chambers below said reading contact element.
Claim 15
Dependent Claim
117 words
A set of contact elements of claim 13 wherein a support surface together with its respective inclination (17) are located elevationally lower for the ground contact element (14) by means of a recess (71) provided in the chamber of the ground contact element, as is the case for the contact chambers of the "regular" reading contacts, and wherein a web portion (27) and a housing section (90) for the chamber of the ground contact element have a larger thickness than thickness (D) provided for a "regular" reading contact so that the abutment surfaces (91) and (28) (in FIG. 6) for the ground contact element are located elevationally lower, than this is true for the "regular" reading contacts.
Claim 16
Dependent Claim
30 words
The set of contact elements of claim 1 wherein the additional contact element is arranged such that its contact surface (52) is below the contact surface said ground contact element.
Claim 17
Dependent Claim
48 words
The set of contact elements of claim 15, wherein said ground contact element comprises an abutment surface (44) formed by an extension of the contact region of said contact element, said abutment surface (44) being adapted to cooperate with an abutment surface (30) formed by a web (29).
Claim 18
Dependent Claim
36 words
The set of contact elements of claim 1 wherein at the bottom surface (21) of the insulating body preferably integrally therewith, a support dome (62) is provided for receiving and supporting the additional contact element (15).
Claim 19
Dependent Claim
30 words
The set of contact elements of claim 17 wherein the additional contact element is biased and abuts in its biased condition at an abutment surface (80) of a web (29).
Claim 20
Dependent Claim
133 words
A set of contact elements for engaging contact zones of a SIM-card, comprising: an insulating body (11) having an upper surface (20) and a bottom surface (21), contact chambers in said insulating bodies, contact elements snappingly located in said contact chambers and biased into a position where they extend with contact cusps beyond the upper surface, an additional switching contact element (15) forming together with one of said contact elements which are adapted for engagement with said contact zones, a card presence switch, and said additional contact element (15) is arranged such that it will be actuated only after the contact elements are in contact engagement with the contact zones of the SIM-card, wherein the additional contact element adapted for cooperation with one of said reading contact elements is a ground contact element.
Claim 21
Dependent Claim
133 words
A set of contact elements for engaging contact zones of a SIM-card, comprising: an insulating body (11) having an upper surface (20) and a bottom surface (21), contact chambers in said insulating bodies, contact elements snappingly located in said contact chambers and biased into a position where they extend with contact cusps beyond the upper surface, an additional switching contact element (15) forming together with one of said contact elements which are adapted for engagement with said contact zones, a card presence switch, and said additional contact element (15) is arranged such that it will be actuated only after the contact elements are in contact engagement with the contact zones of the SIM-card, wherein the additional contact element adapted for cooperation with one of said reading contact elements is a ground contact element.
