<P>PROBLEM TO BE SOLVED: To achieve a differential transmission contact which has a low attenuation for transmission of a differential signal, is easy to be bent, and can be produced inexpensively. <P>SOLUTION: The differential transmission contact has a structure that a shield conductor 5 is stuck to the lower surface of a rectangular dielectric sheet 4, belt-like ground conductors 2 extending into the transmission direction along the both right and left edges toward the transmission direction are stuck to the upper surface, the shield conductor 5 and the belt-like ground conductor 2 are connected by first bridge portions 3 in a shape of a ladder at a thick portion of the dielectric sheet, and signal conductors 1 are stuck to the dielectric sheet 4 at respective predetermined spacings from the ground conductors 2 on the both sides. This makes no dielectric body be on the surface sides of the signal conductor 1 and the ground conductor 2, so that the differential transmission connector has a small quantity of transmission attenuation, this makes the ground conductors 2 and the shield conductor 5 connected in a shape of a ladder, so that the differential transmission connector is easy to be bent, and this allows all the conductors to be manufactured in succession by punching, so that the differential transmission contact is inexpensive. <P>COPYRIGHT: (C)2009,JPO&INPIT |
