Abstract
Abstract The connector comprises an insulating support 20 in which are provided uniformly spaced passages and electrical signal contacts, each intended to connect a pad and a track, which are arranged in at least some of the passages. The contacts are each constituted by a cut-out sheet, having a relatively rigid portion comprising a branch for bearing on the lower face of the support and for connection with a track and a branch for fastening onto the support (20), extending towards the upper face and having a relatively flexible S-shaped portion whose proximal end is integral with the relatively rigid portion and whose distal end projects beyond the upper face of the support, the flexible portion having curvatures at rest such that the distal end is then away from the fastening branch and the passage having dimensions such that it deforms the flexible portion when the contact is inserted into the support until it brings the distal portion into connection with the fastening branch, in order to constitute a short-circuit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
An intermediate connector intended to be mounted on a printed-circuit board and to receive an active electronic circuit substrate by connecting contact pads provided on the lower face of the substrate to tracks of the board, comprising an insulating support in which are provided uniformly spaced passages and electrical signal contacts, each intended to connect a pad and a track and arranged in at least some of the passages, wherein the contacts are each constituted by a cut-out sheet, having a relatively rigid portion comprising a branch for bearing on the lower face of the support and for connection with a track and a branch for fastening onto the support, extending towards the upper face and having a relatively flexible S-shaped portion whose proximal end is integral with the relatively rigid portion and whose distal end projects beyond the upper face of the support, the flexible portion having curvatures at rest such that the distal end is then away from the fastening branch and the passage having dimensions such that it deforms the flexible portion when the contact is inserted into the support until it brings the distal portion into connection with the fastening branch, in order to constitute a short-circuit.
Claim 2
Dependent Claim
201 words
An intermediate connector intended to be mounted on a printed-circuit board and to receive an active electronic circuit substrate by connecting contact pads provided on the lower face of the substrate to tracks of the board, comprising an insulating support in which are provided uniformly spaced passages and electrical signal contacts, each intended to connect a pad and a track and arranged in at least some of the passages, wherein the contacts are each constituted by a cut-out sheet, having a relatively rigid portion comprising a branch for bearing on the lower face of the support and for connection with a track and a branch for fastening onto the support, extending towards the upper face and having a relatively flexible S-shaped portion whose proximal end is integral with the relatively rigid portion and whose distal end projects beyond the upper face of the support, the flexible portion having curvatures at rest such that the distal end is then away from the fastening branch and the passage having dimensions such that it deforms the flexible portion when the contact is inserted into the support until it brings the distal portion into connection with the fastening branch, in order to constitute a short-circuit.
Claim 3
Dependent Claim
23 words
The connector as claimed in claim 1, wherein the bearing branch comprises an enlarged terminal region which can be soldered onto the board.
Claim 4
Dependent Claim
47 words
The connector as claimed in claim 1, wherein the passages are parallel to each other and are each constituted by a fraction of a slot provided in the support, separated by a partition from the other fraction of the slot, the second fraction receiving another signal contact.
Claim 5
Dependent Claim
102 words
The connector as claimed in claim 3, wherein the electrical contacts are of two different types, the contacts of one type having a bearing branch of a length different from that of the bearing branch of the contacts of the other type, and wherein each slot contains two contacts of different types whose bearing branches are directed in opposite directions, the partitions being placed so that the arrangement of the contacts is reversed in two successive slots in order that the distal ends are staggered over four rows while the ends for bearing onto the printed circuit are aligned in two rows.
Claim 6
Dependent Claim
82 words
The connector as claimed in claim 1, which moreover comprises equipotential contacts, each equipotential contact being constituted by a cut-out sheet occupying a passage parallel to the passages which receive the electrical signal contacts, having two fastening arms directed in opposite directions and connected to a plate provided with two contacts projecting beyond the upper face of the support, the said plate being connected via an elastic arm to the bearing branches and provided with a projection for short-circuiting the elastic arm.
Claim 7
Dependent Claim
40 words
The connector as claimed in claim 1, wherein each fastening arm comprises a terminal hook intended to engage upon the support, the distance of which to the bearing branch is such that the contact has a play within the support.
Claim 8
Dependent Claim
36 words
The connector as claimed in claim 1, wherein the support consists of connection strips arranged over all the sides of the substrate and provided with means for locating onto the printed-circuit board and onto the substrate.
Claim 9
Dependent Claim
42 words
The connector as claimed in claim 7, wherein the means for locating onto the board are placed at the ends of the connection strips and wherein the means for locating onto the substrate are placed in the middle of the connection strip.
Claim 10
Dependent Claim
20 words
The connector as claimed in claim 1, wherein the substrate is constituted by a multilayer ceramic board carrying several components.
Claim 11
Dependent Claim
41 words
The connector as claimed in claim 1, which also comprises a framework-shaped stiffener, fixed to the board and surrounding the support, and a pressure plate exerting a calibrated bearing force on the edge of the substrate via of a covering lid.
