Abstract:
A right-angle connector unit for making electrical and removable connections between first and second electrical devices, which comprises a first right-angle connector (100) connected to said first electrical device, a second right-angle connector (200) connected to said second electrical device, and a cable connector (400) having flexibility and being removably connected between said first and said second right-angle connectors, said first right-angle connector comprising a first base portion (101) facing a connection part of said first electrical device, a first vertical portion (102) extending substantially perpendicular to said first base portion, and first through n-th primary contacts (103-1 to 103-n) n being an integer but not smaller than 2, said contacts extending in parallel with one another between said first base and said first vertical portions, each of said first through said n-th primary contacts having one end and another end, respectively, said one end of said first through said n-th primary contacts being arranged in a first primary direction along said first base portion with spaces left between adjacent ones of said ends and being formed to be connected to said connection part of said first electrical device, the other end of each of said first through said n-th primary contacts being arranged in a second primary direction perpendicular to said first primary direction along said first vertical portion with spaces left between adjacent ones of said ends and being formed to be connected to one end of said cable connector, an i-th primary contact, i being an integer larger than 1 but not larger than n, of said first through said n-th primary contacts being longer than an (i-1)-th primary contact, said second right-angle connector comprising a second base portion (201) facing a connection part of said second electrical device, a second vertical portion (202) extending substantially perpendicular to said second base portion, and first through n-th secondary contacts (203-1 to 203-n) extending in parallel with one another between said second base and said second vertical portions, each of said first through said n-th secondary contacts having one end and the other end, one end of each of said first through said n-th secondary contacts being arranged in a first secondary direction along said second base portion with spaces left between adjacent ones and being formed to be connected to said connection part of said second electrical device, the other end of each of said first through said n-th secondary contacts being arranged in a second secondary direction perpendicular to said first secondary direction along said second vertical portion with spaces left between adjacent ones of said ends and being formed to be connected to one end of said cable connector, an i-th secondary contact of said first through said n-th secondary contacts being longer than an (i-1)-th secondary contact, said cable connector comprising first through n-th conductors (401-1 to 401-n) equal to one another in length, wherein:a first contact-combination formed by said first primary contact (103-1) and said n-th secondary contact (203-n) through an n-th contact-combination formed by said n-th primary contact (103-n) and said first secondary contact (203-1) are substantially equal in length to one another;said first through said n-th conductors (401-1 to 401-n) connect said first through said n-th primary contacts (103-1 to 103-n) of said first right-angle connector (100) with said n-th through said first secondary contacts (203-n to 203-1) of said second right-angle connectors (200), respectively,a first signal path (P.sub.AD) being formed by said first contact-combination (103-1 and 203-n) and said first conductor (431-1) through an n-th signal path (P.sub.BC) formed by said n-th contact-combination (103-n and 203-1) and said n-th conductor (431-n) being substantially equal to one another in length.
