Patent ID: 8128432

Claim:
Insert including at least three contacts ( 101 to 108 ) having substantially linear parts characterized in that it further includes at least one three-pole capacitor ( 141 , 143 , 145 , 144 , 146 , 148 ) between three of said contacts ( 101 , 103 , 105 , 104 , 106 , 108 ), one of the contacts ( 103 , 106 ) of each three-pole capacitor being connected to a central plate ( 143 , 146 ), a first dimension ( 711 ) of the central plate in the direction perpendicular to said substantially linear parts being greater than a second dimension ( 712 ) in a direction parallel to said substantially linear parts, said second dimension defining the widths of the areas of said central plate, the average width of said central plate between the areas in which said central plate faces other plates, referred to as “lateral” plates ( 141 , 145 , 144 , 148 ), connected to the other contacts of said three-pole capacitor being greater than one third of the average width of said central plate in said areas.
