Abstract
Abstract Disclosed is a device for setting up electrical contact among conductors distributed between a first element and a second element, the setting up of the contact between the conductors having to be made when the first element is in a determined position with respect to the second element. The devices has, inter alia a means to guide the first element towards the determined position and a stop designed to stop the first element when it has reached this determined position, this stop comprising means enabling the conductors to be gradually put into contact.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A device for setting up electrical contact among conductors (14) distributed between a first element (20) and a second element (3), the setting up of the contact between the conductors having to be made when the first element (20) is in a pre-determined position with respect to the second element (14-3), the device being solidly joined to the second element, said device including: means for guiding (1) the first element toward said determined position; a stop (8) designed to stop the first element (20) when it has reached said determined position, said stop comprising means (9) enabling said conductors to be gradually put into contact, said device further including a flexible strip (2) formed by an arm(7), fixed by one of its ends (5,6) to said guiding means (1), the other end of which is extended by a part (8) forming said stop.
Claim 2
Independent Claim
143 words
A device for setting up electrical contact among conductors (14) distributed between a first element (20) and a second element (3), the setting up of the contact between the conductors having to be made when the first element (20) is in a pre-determined position with respect to the second element (14-3), the device being solidly joined to the second element, said device including: means for guiding (1) the first element toward said determined position; a stop (8) designed to stop the first element (20) when it has reached said determined position, said stop comprising means (9) enabling said conductors to be gradually put into contact, said device further including a flexible strip (2) formed by an arm(7), fixed by one of its ends (5,6) to said guiding means (1), the other end of which is extended by a part (8) forming said stop.
Claim 3
Dependent Claim
10 words
Memory card reader, comprising a device according to claim 1.
Claim 4
Dependent Claim
25 words
A device according to claim 1, wherein the means enabling the conductors to be gradually placed in contact are formed by a sloping part (4).
Claim 5
Dependent Claim
27 words
A device according to claim 3, wherein the conductors (14) of the second element (3) are supported by a contact-holder (3) fixed to the flexible strip (2).
Claim 6
Dependent Claim
28 words
A device according to claim 4, wherein the conductors (14) of the second element (3) are folded, in the contact establishing zone, in an elastically deformable cross shape.
Claim 7
Dependent Claim
219 words
An electronic card reader contact assembly comprising a card guide (1) for receiving and guiding an inserted electronic memory card having exposed electric contacts on a first path, an elongated flexible strip (2) cantilever mounted at one location (6) to said card guide (1), and having at its cantilevered end a stop part and a sloping portion, said sloping portion normally aligned at one end of said first path and sloping from said path towards said flexible strip, and stop part joining said sloping portion to said flexible strip, and defining the end of said path, said stop member having a face substantially perpendicular to said path, a contact holder (3) mounted on said flexible strip between said one location where the flexible strip is cantilevered mounted and said stop at the cantilevered end, and having contacts (14) extending beyond one face thereof adjacent to said path when in its normal position, whereby when a card is inserted in the guide it travels along said guide until the card engages the sloping portion, which then, as the card is inserted further, pulls the flexible strip and the card towards one another until the end of the card reaches the stop, and simultaneously, the contacts on the contact holder is drawn towards, and into contact with, contacts on the card.
Claim 8
Dependent Claim
219 words
An electronic card reader contact assembly comprising a card guide (1) for receiving and guiding an inserted electronic memory card having exposed electric contacts on a first path, an elongated flexible strip (2) cantilever mounted at one location (6) to said card guide (1), and having at its cantilevered end a stop part and a sloping portion, said sloping portion normally aligned at one end of said first path and sloping from said path towards said flexible strip, and stop part joining said sloping portion to said flexible strip, and defining the end of said path, said stop member having a face substantially perpendicular to said path, a contact holder (3) mounted on said flexible strip between said one location where the flexible strip is cantilevered mounted and said stop at the cantilevered end, and having contacts (14) extending beyond one face thereof adjacent to said path when in its normal position, whereby when a card is inserted in the guide it travels along said guide until the card engages the sloping portion, which then, as the card is inserted further, pulls the flexible strip and the card towards one another until the end of the card reaches the stop, and simultaneously, the contacts on the contact holder is drawn towards, and into contact with, contacts on the card.
Claim 9
Dependent Claim
52 words
An assembly according to claim 6 wherein said card guide (1) includes a slot (4) which has fixed parallel flat faces for receiving said card into said slot parallel thereto, whereby contact is made to said contacts on said card without any pivoting of said card at the entrance of the slot.
