Connectors for printed-circuit cards

Claim 2

A connecting system for detachably connecting conductive surfaces aligned on the faces of a number N of printed-circuit cards with a conductive surfaces on a printed-circuit panel, said system comprising: a number N+1 of connector elements fixed parallel to said panel in order to permit the insertion of an edge of one of said cards between two adjacent connector elements, each of said elements comprising: an elongated body of insulating material having two lateral walls, each lateral wall being formed with a plurality of recesses a push member slidably disposed in each of said recesses, said push member consisting of insulating material and being provided with bosses, a spring element fixed in said body and provided with two sets of spring blades, each of said spring blades being disposed to urge one of said push members through the corresponding recess in order that the bosses of said push member may project outside of the associated lateral wall, and two series of elongated contact blades, each of said blades having one end thereof bonded to a conductive surface on said panel between the latter and an opposed connector body and having a central portion disposed opposite to an associated one of said push members whereby said central portion is urged towards a conductive surface on a printed-circuit card when the latter is inserted between two adjacent connector elements.

Claim 3

A connecting system according to claim 1, wherein each of said push members is provided with two bosses to transmit to two separate points of a contact blade the force which is applied thereto by the corresponding spring blade.

Claim 4

A connecting system according to claim 2, wherein for each of said connector elements, said contact blades consist of thin strips of conductive metal deposited upon a thin sheet of insulating material, which sheet is gripped between said panel and the corresponding connector body and has its two edges turned down one upon the other and fixed on said connector body.

Claim 5

A connecting system according to claim 3, wherein each of said sheets consists of a material resistant to the tin-soldering temperature, such as polyethylene terephthalate.

Claim 6

A connecting arrangement for detachably connecting a plurality of conductive surfaces, disposed on at least one face of a circuit board and spaced apart along one edge of said face, to conductive surfaces disposed on one face of a connection panel, said connecting arrangement being provided with at least one connector element comprising: an elongated connector body of insulating material mounted on said one face of said connection panel, the elongated dimension of said body being oriented parallel to the plane of said one face of said connection panel and a lateral wall of said body extending along the length thereof being tangent to a plane perpendicular to the plane of said one face of said connection panel, said wall being provided with a plurality of apertures extending therethrough, a push member slidably disposed in each of said apertures, a spring member mounted in said body for each of said push members, each of said spring members being disposed to urge the associated push member through the corresponding aperture to project outwardly from said lateral wAll, and a plurality of elongated contact strips spaced apart along the length of said lateral wall and oriented transversely to the length of said lateral wall, each of said strips having one end thereof bonded to one of said conductive surfaces disposed on said one face of said connection panel between said panel and said connector body, having a central portion thereof disposed opposite to a respective one of said push members to provide for said control portion to be urged away from said wall by the corresponding push member, and having the other end thereof affixed to said body near the edge of said lateral wall remote from said panel.

Claim 7

A connecting arrangement for detachably connecting a plurality of conductive surfaces, disposed on at least one face of a circuit board and spaced apart along one edge of said face, to conductive surfaces disposed on one face of a connection panel, said connecting arrangement being provided with at least one connector element comprising: an elongated connector body of insulating material mounted on said one face of said connection panel, the elongated dimension of said body being oriented parallel to the plane of said one face of said connection panel and a lateral wall of said body extending along the length thereof being tangent to a plane perpendicular to the plane of said one face of said connection panel, said wall being provided with a plurality of apertures extending therethrough, a push member slidably disposed in each of said apertures, a spring member mounted in said body for each of said push members, each of said spring members being disposed to urge the associated push member through the corresponding aperture to project outwardly from said lateral wAll, and a plurality of elongated contact strips spaced apart along the length of said lateral wall and oriented transversely to the length of said lateral wall, each of said strips having one end thereof bonded to one of said conductive surfaces disposed on said one face of said connection panel between said panel and said connector body, having a central portion thereof disposed opposite to a respective one of said push members to provide for said control portion to be urged away from said wall by the corresponding push member, and having the other end thereof affixed to said body near the edge of said lateral wall remote from said panel.

Claim 8

The arrangement of claim 5 provided with a plurality of said connector elements, the respective connector bodies of said connector elements being oriented mutually parallel and spaced apart to admit the edge of one of said circuit boards between adjacent pairs of said bodies.

Claim 9

The arrangement of claim 5 for detachably connecting a plurality of said conductive surfaces disposed on both faces of a circuit board to conductive surfaces on said panel and provided with a pair of said connector elements, the respective connector bodies of said connector elements being oriented mutually parallel and with the respective lateral walls of said bodies facing each other, said connector bodies being spaced apart to admit the edge of one of said circuit boards between said facing lateral walls.
