Electrical coupling arrangement

Claim 2

An electrical coupling arrangement comprising, in combination with a pair of conductors, a pair of like coupling elements each having a front side formed with a plug and next to said plug with a first jack, and a back side formed with a second jack, whereby said front sides of said elements are mutually matable with each of said plugs engaged in the first jack of the other element; and a respective second plug on each of said conductors, each of said second plugs being engageable in a respective one of said second jacks, said elements being each formed of a pair of metallic plates having a central region between said sides connect the plates together, said plates being formed at said front side with a cleft and being spread apart to one side of said cleft to form said first jack, said plates being spread apart at said back side to form said second jack.

Claim 3

The arrangement defined in claim 1 wherein at least one of said plates is formed in each of said jacks with a transverse notch, each of said elements being provided with a metallic strip received in said notch and formed with a plurality of longitudinally extending cuts subdividing said strip centrally into a plurality of tongues, each of said tongues being twisted relative to said strip and projecting into the respective jack, whereby a plug introduced into the jack engages resiliently against said tongues.

Claim 4

An electrical coupling arrangement comprising, in combination with a pair of conductors, a pair of like coupling elements each having a front side formed with a plug and next to said plug with a first jack, and a back side formed with a second jack, whereby said front sides of said elements are mutually matable with each of said plugs engaged in the first jack of the other element; and a respective second plug on each of said conductors, each of said second plugs being engageable in a respective one of said second jacks, said elements being each formed of a pair of metallic plates having a central region between said sides connect the plates together, said plates being formed at said front side with a cleft and being spread apart to one side of said cleft to form said first jack, said plates being spread apart at said back to form said second jack, each of said conductors having a generally flat band and the respective second plug being a flat bar having a width substantially equal to the width of the respective second jack, said bar having a beveled forward edge insertable into the respective second jack, and second jacks having respective inwardly facing parallel surfaces confronting outwardly facing parallel surfaces of the respective second plug substantially coextensive with said surfaces of said second jacks.

Claim 5

An electrical coupling arrangement comprising, in combination with a pair of conductors, a pair of like coupling elements each having a front side formed with a plug and next to said plug with a first jack, and a back side formed with a second jack, whereby said front sides of said elements are mutually matable with each of said plugs engaged in the first jack of the other element; and a respective second plug on each of said conductors, each of said second plugs being engageable in a respective one of said second jacks, said elements being each formed of a pair of metallic plates having a central region between said sides connect the plates together, said plates being formed at said front side with a cleft and being spread apart to one side of said cleft to form said first jack, said plates being spread apart at said back to form said second jack, each of said conductors having a generally flat band and the respective second plug being a flat bar having a width substantially equal to the width of the respective second jack, said bar having a beveled forward edge insertable into the respective second jack, and second jacks having respective inwardly facing parallel surfaces confronting outwardly facing parallel surfaces of the respective second plug substantially coextensive with said surfaces of said second jacks.

Claim 6

The arrangement defined in claim 3 wherein each of said first plugs has a thickness equal to substantially twice the thickness of said plates and a pair of outwardly facing surfaces confronting inwardly facing surfaces of the first jack receiving same, said first plugs having beveled forward edges insertable ito the respective first jack.

Claim 7

The arrangement defined in claim 4 wherein at least one of said surfaces is formed with a transverse groove of dovetail cross section extending perpendicular to the direction of insertion of said plugs into said jacks, and a respective bowed contact strip received in said groove.

Claim 8

The arrangement defined in claim 5 wherein said contact strip is formed with a plurality of slits parallel to said direction and a subdividing the strip into a multiplicity of parallel contacts.

Claim 9

The arrangement defined in claim 6 wherein each of said parallel contacts is twisted relative to the plane of the surface in which the contact strip is received to present an edge to the confronting surface.

Claim 10

The arrangement defined in claim 7, further comprising means ensuring interconnection of said elements prior to electrical connection of at least one of said second plugs with the respective coupling element upon assembly of said elements and said second plug.
