Abstract: An electric connector set having an impedance adjustment function and a mounting structure, and including a first connector that mounts onto a first circuit board, and a second connector that mounts onto a second circuit to be insertable into and withdrawable from the first connector in an insertion-withdrawal direction. The first connector includes a first connection terminal having first mounting portions to mount onto first land portions on the first circuit board and a first insulating member that holds the first connection terminal. The second connector includes a second connection terminal having second mounting portions to mount onto second land portions on the second circuit board and a second insulating member that holds the second connection terminal. In an engagement state of the electric connector set, the first mounting portions oppose the second mounting portions and overlap the second mounting portions as viewed in the insertion-withdrawal direction.

Abstract: A multi-pole connector set for suppressing electromagnetic wave interference between inner terminals disposed in the same rows. The multi-pole connector set includes a first connector and a second connector mating with each other. The first connector includes first inner terminals arrayed in a plurality of rows, a first insulating member, and a first shield member located between the rows of the first inner terminals. The second connector includes second inner terminals arrayed in a plurality of rows and a second insulating member. The multi-pole connector set further includes connection parts that connect the first shield member and the second inner terminals to each other.

Abstract: When a multipole connector set is viewed from a height direction and when a first ground terminal assembly, a first signal terminal assembly, and a second ground terminal assembly are arranged in a length direction as follows: A connection portion at the outermost side in a width direction of the first ground terminal assembly is a first connection portion, a connection portion at the outermost side in the width direction of the second ground terminal assembly is a second connection portion, a connection portion arranged at the innermost side in the width direction of the first ground terminal assembly is a third connection portion, and a connection portion at the innermost side in the width direction of the second ground terminal assembly is a fourth connection portion. All connection portions of the first signal terminal assemblies are inside a quadrangle connecting the first, second, third and fourth connection portions.

Abstract: An electrical connector set includes a first substrate having a first conductor, and a first internal terminal having a first mounting portion and a second mounting portion that are mounted on the first conductor of the first substrate and a projecting portion extending in a curved shape between the first mounting portion and the second mounting portion.

Abstract: In a connector, first, second, third and fourth terminals are disposed to satisfy conditions (A) and (B): (A) (a1) a left-end of the first terminal is positioned to left of a left-end of the fourth terminal, and a distance between the left-end of the first terminal and the left-end of the fourth terminal in a left-right direction is shorter than a first distance, or (a2) the left-end of the first terminal coincides with the left-end of the fourth terminal in the left-right direction, (B) (b1) a right-end of the second terminal is positioned to left of a right-end of the third terminal, and a distance between the right-end of the second terminal and the right-end of the third terminal in the left-right direction is shorter than a second distance, or (b2) the right-end of the second terminal coincides with the right-end of the third terminal in the left-right direction.

Abstract: A first connector of a connector set includes first internal terminals, a first insulation member that fixes the first internal terminals, and first external terminals having a surrounding shape portion that surrounds the first internal terminals and the first insulation member. The second connector includes second internal terminals, a second insulation member that fixes the second internal terminals, and a second external terminal having a surrounding shape portion that surrounds the second internal terminals and the second insulation member. The first external terminals have cutout portions at a portion that is part of the surrounding shape portion of the first external terminal and faces a ground conductor formed at a mounting position of the second connector of the second circuit substrate.

Abstract: A multipolar connector includes a first signal terminal, a first ground terminal, an insulating member that holds the first signal and ground terminals, and an external terminal along a periphery of the insulating member. The first signal and ground terminals are arranged side by side in a direction parallel to an X-axis, extend in a direction parallel to a Y-axis orthogonal to the X-axis, and each have a first end serving as a mount portion that connects to and mounts on a mount electrode on a circuit board. When viewed in a direction parallel to a Z-axis orthogonal to the directions parallel to the X and Y axes, a mount portion of the first signal terminal is within a layout area of the external terminal. When viewed in the direction parallel to the Z-axis, a mount portion of the first ground terminal is outward from the mount portion.

Abstract: A connector includes a plurality of inner terminals and an outer terminal. The plurality of inner terminals are arrayed with intervals therebetween in a direction. The plurality of inner terminals are terminals that are connected to a ground potential. The outer terminal is disposed around the group of the plurality of arrayed inner terminals and are connected to a ground potential. The outer terminal includes side wall members that are shaped so as to extend in the direction and be parallel to the plurality of inner terminals. The inner terminals include connection parts that are connected to the side wall members.
