Abstract
Abstract A low impedance surface connector is arranged on a printed board (10) with printed contacts (1-6) formed by the printed conductors. The contacts (2, 3; 5, 6) for the ground and the sheath are situated in conducting relationship symmetrically on both sides of the signal contact (1; 4) in the plane of the printed board surface (11, 12).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
Surface connector arrangement, comprising: a printed circuit board having a planar surface; a ground contact having two legs extending on said surface and into contact with each other for providing a ground; and an elongated signal contact extending on said surface and between said legs for enabling transmission of radio frequency signals, said elongated signal contact being spaced from said ground contact, each of said contacts being arranged for connecting to other contacts on another printed circuit board, said printed circuit board having another surface extending adjacent and substantially perpendicular to said planar surface, said ground and signal contacts extending onto said another surface as respective contact faces.
Claim 2
Dependent Claim
108 words
Surface connector arrangement, comprising: a printed circuit board having a planar surface; a ground contact having two legs extending on said surface and into contact with each other for providing a ground; and an elongated signal contact extending on said surface and between said legs for enabling transmission of radio frequency signals, said elongated signal contact being spaced from said ground contact, each of said contacts being arranged for connecting to other contacts on another printed circuit board, said printed circuit board having another surface extending adjacent and substantially perpendicular to said planar surface, said ground and signal contacts extending onto said another surface as respective contact faces.
Claim 3
Dependent Claim
25 words
A surface connector as in claim 1, wherein said ground contact is U-shaped and said legs extend symmetrically on both sides of said signal contact.
Claim 4
Dependent Claim
30 words
A surface connector as in claim 1, wherein said ground and signal contacts lie in substantially the same plane as said planar surface at locations away from said contact faces.
Claim 5
Dependent Claim
25 words

Claim 7
Dependent Claim
52 words
A surface connector as in claim 1, wherein said printed circuit board has protruding fingers spaced from each other, said ground and signal contacts extending in the same plane as said planar surface onto respective ones of said fingers, said fingers each having a free end from which extends said another surface.
Claim 8
Dependent Claim
48 words
A surface connector as in claim 1, wherein said printed circuit has protruding fingers spaced from each other and notches between adjacent ones of said fingers, said legs and said signal contact extending to a bottom of said notches and onto said another surface, as said contact faces.
Claim 9
Dependent Claim
17 words
A surface connector as in claim 5, 6, or 7, wherein said fingers protrude through a housing.
Claim 10
Dependent Claim
