摘要： The supported portions of the substrate are positioned offset from the center of the substrate in the vertical direction; adjacent intermediate bodies are provided in orientations vertically inverted relative to each other and every two supported portions are positioned so as to differ by a predetermined dimension P in the vertical direction; the lower lateral walls of the housing have formed therein, in an alternating manner, first lower supporting portions and second lower supporting portions positioned so as to differ by the predetermined dimension P in the vertical direction; the first lower supporting portions protrude upwardly of the second lower supporting portions and support from below the supported portions of the intermediate bodies in which the supported portions are positioned with an upward offset; and the second lower supporting portions support from below the supported portions of the intermediate bodies in which the supported portions are positioned with a downward offset.

摘要： The intermediate circuit board has a plate-shaped substrate and a plurality of signal transmission line pairs for differential signal transmission extending on a major face of the substrate from one end to the other end of the substrate in the direction of connection to the counterpart connect bodies; the substrate has a fiber cloth formed by braiding a plurality of fibers used to reinforce the substrate in a mesh pattern and a plate-like member made of plastic having the fiber cloth embedded therein; the plurality of signal transmission line pairs have straight pairs and cross pairs disposed in an alternating manner in the width direction of the substrate; and the straight pairs and cross pairs, when viewed in the through-thickness direction of the substrate, are formed extending inclined at an angle relative to the fibers of the fiber cloth.

摘要： [Problem] To provide an electrical connector capable of adequately ensuring a stable state of electrical communication between ground members.
[Means of Solution] The retaining member, which retains rows of signal transmission paths consisting of multiple signal transmission paths arranged side by side in a direction along the major faces of the retaining member together with a first and a second ground member, has perforation portions extending in the through-thickness direction of the retaining member at locations between adjacent signal transmission paths; the electrical connector has provided therein a shorting member of electrically conductive plastics co-molded with the first ground member and second ground member; and the shorting member has first base portions that are located at the first ground member side and are in contact with the first ground member, second base portions that are located at the second ground member side and are in contact with the second ground member, and coupling portions that are located within the perforation portions and couple the first base portions and the second base portions.-

摘要： The first terminals have contact arm portions extending in a rectilinear manner in the direction of connector plugging and unplugging; the second terminals have convex contact point portions contactable with an intermediate portion of the contact arm portions in the same direction. When the stub portions of the contact arm portions are divided into a free end side range and a proximal end side range such that the center point of said stub portions in the direction of plugging and unplugging forms a boundary, in the arranged state of the first terminals, impedance at arbitrary locations in the direction of plugging and unplugging within the free end side range is larger than impedance at arbitrary locations in the plugging direction within the proximal end side range.
