Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 259 words
A transition connector comprising insulative support means including parallel upper and lower plane surfaces and supporting a multiplicity of identical contact elements each having a bifurcate plate U-contact upper terminal extending perpendicularly and to a common distance from said upper surface and a lower terminal extending perpendicularly and to a common distance from said lower surface, said upper terminals being uniformly spaced apart by a first distance, said lower terminals being uniformly spaced apart by a second distance different from said first distance, the upper and lower terminals of each said contact element being connected by a single deformable flat strap having its major faces in planes perpendicular to the major faces of the bifurcate plate contact of the contact element, the straps of the contact elements central of said connector being more severely deformed than those at the ends of said connector, said support means including an inner carrier body having a crenelated lower edge and fitting within an outer trough-like container having a perforate base and a multi-notched upper inner edge, the crenels of said lower edge being spaced apart by said second distance to receive said lower terminals, the notches of said upper edge being spaced apart by said first distance to receive said upper terminals, the base of said container being perforate to receive said lower terminals, said carrier body being channeled along its edge to provide free space for the said deformable straps of said contact elements, and each said contact element including anchor means for anchoring said contact element to said carrier body.
Claim 2
Dependent Claim 259 words
A transition connector comprising insulative support means including parallel upper and lower plane surfaces and supporting a multiplicity of identical contact elements each having a bifurcate plate U-contact upper terminal extending perpendicularly and to a common distance from said upper surface and a lower terminal extending perpendicularly and to a common distance from said lower surface, said upper terminals being uniformly spaced apart by a first distance, said lower terminals being uniformly spaced apart by a second distance different from said first distance, the upper and lower terminals of each said contact element being connected by a single deformable flat strap having its major faces in planes perpendicular to the major faces of the bifurcate plate contact of the contact element, the straps of the contact elements central of said connector being more severely deformed than those at the ends of said connector, said support means including an inner carrier body having a crenelated lower edge and fitting within an outer trough-like container having a perforate base and a multi-notched upper inner edge, the crenels of said lower edge being spaced apart by said second distance to receive said lower terminals, the notches of said upper edge being spaced apart by said first distance to receive said upper terminals, the base of said container being perforate to receive said lower terminals, said carrier body being channeled along its edge to provide free space for the said deformable straps of said contact elements, and each said contact element including anchor means for anchoring said contact element to said carrier body.
Claim 3
Dependent Claim 31 words
The transition connector of claim 1 wherein said carrier body is provided with an edge perforation adjacent each said crenel and each said anchor means is retained within a said perforation.
Claim 4
Dependent Claim 28 words
The transition connector of claim 1 wherein said U-contacts are contained within the notches in said container and said lower terminals extend through the perforations in said base.
Claim 5
Dependent Claim 13 words
The transition connector of claim 3 wherein said lower terminals are male terminals.
Claim 6
Dependent Claim 21 words
The transition connector of claim 3 wherein said lower terminals are female terminals and including a perforate insulator surrounding said terminals.
Claim 7
Dependent Claim 22 words
The transition connector of claim 1 including a cover member fitting against said upper plane surface and slotted to receive said U-contacts.
Claim 8
Dependent Claim 40 words
The transition connector of claim 1 wherein said contact element anchor means comprises a flat plate adjacent said flat strap with its major faces in planes perpendicular to the major faces of said flat strap and said bifurcate plate U-contact.
Claim 9
Dependent Claim 18 words
The transition connector of claim 17 wherein said contact element anchor means terminates in opposing outwardly barbed arms.
