Connecting-strip for plug-in cards and a connector fitted with connecting-strips of this type

Claim 2

A plug-in card connecting strip, comprising: a parallelepiped base and a cover plate supporting a plurality of electrical contact elements endowed with elasticity, the cover-plate being capable of pivotal displacement about a longitudinal axis parallel to the base into either an open or closed position, the open position being for inserting the edge of a card and the closed position being for placing the respective conductive elements of the connecting strip and of the card in contact with each other, the closing action being produced by a clip having a generally U-shaped section including an intermediate portion and two arms, the clip being positioned parallel to the longitudinal axis of the strip with the two arms thereof being applied to respective zones of the base and cover-plate so that the clip deforms, thus ensuring closure by application of a force produced by elastic deformed clip, the arm of the clip which is applied against the cover plate being provided substantially at the ends thereof with bearing elements capable of pivoting within corresponding recesses in the cover plate.

Claim 3

A connecting strip according to claim 1 wherein the bearing elements comprise pivot pins.

Claim 4

A connecting strip according to claim 1 or 2 wherein the intermediate portion of the clip has an opening therein.

Claim 5

A connecting strip according to claim 3 further including an elbowed lever having a lever arm positioned through the opening and an elbow portion positioned between the base and the intermediate portion of the clip, whereby an opening of the connecting strip is effected by the rotational displacement of the lever arm about a direction parallel to the longitudinal axis of the connecting strip.

Claim 6

A plug-in card connector comprising a plurality of strips according to claim 1 or 2.

Claim 7

A plug-in card connector comprising a plurality of strips according to claim 3.

Claim 8

A plug-in card connector comprising a plurality of strips according to claim 4.

Claim 9

A connecting strip for plug-in card having electrical contact elements comprising: a generally parallelepiped base member; a cover plate member; a plurality of electrical contact elements endowed with elasticity supported by the base and cover plate members, the cover-plate member being capable of pivotal displacement about a longitudinal axis parallel to the base into either an open or closed position, the open position being for inserting the edge of a card and the closed position being for placing the respective conductive elements of the connecting strip and of the card in contact with each other, the cover plate member including two projections on an upper surface thereof; and a clip for producing a closing action of the base and cover plate members, the clip being formed in a generally U-shaped section including an intermediate portion and two arms of unequal length, the clip being positioned parallel to the longitudinal axis of the strip with the two arms thereof being applied to respective zones of the base and cover-plate so that the clip deforms, thus ensuring closure by application of a force produced by the deformed clip, the clip further including two openings cooperating with the projections on the upper surface of the cover plate.

Claim 10

A connecting strip for plug-in card having electrical contact elements comprising: a generally parallelepiped base member; a cover plate member; a plurality of electrical contact elements endowed with elasticity supported by the base and cover plate members, the cover-plate member being capable of pivotal displacement about a longitudinal axis parallel to the base into either an open or closed position, the open position being for inserting the edge of a card and the closed position being for placing the respective conductive elements of the connecting strip and of the card in contact with each other, the cover plate member including two projections on an upper surface thereof; and a clip for producing a closing action of the base and cover plate members, the clip being formed in a generally U-shaped section including an intermediate portion and two arms of unequal length, the clip being positioned parallel to the longitudinal axis of the strip with the two arms thereof being applied to respective zones of the base and cover-plate so that the clip deforms, thus ensuring closure by application of a force produced by the deformed clip, the clip further including two openings cooperating with the projections on the upper surface of the cover plate.

Claim 11

A connecting strip according to claim 8 further comprising bearing elements formed substantially at ends of the arm in contact with the cover plate member for pivoting the clip within corresponding recesses formed in the cover plate.

Claim 12

A connecting strip according to claim 9 wherein the bearing elements comprise pivot pins.

Claim 13

A connecting strip according to claim 8, 9 or 10 wherein the intermediate portion of the clip has an opening therein.

Claim 14

A connecting strip according to claim 11 further including an elbowed lever having a lever arm positioned through the opening and an elbow portion positioned between the base and the intermediate portion of the clip, whereby an opening of the connecting strip is effected by the rotational displacement of the lever arm about a direction parallel to the longitudinal axis of the connecting strip.

Claim 15

A plug-in card connector comprising a plurality of strips according to claim 8, 9 or 10.

Claim 16

A plug-in card connector comprising a plurality of strips according to claim 11.

Claim 17

A plug-in card connector comprising a plurality of strips according to claim 12.
