Abstract

A connector includes plural terminals, a housing holding the terminals, and an inner shield. The connector is configured to be connected to a mating connector by moving toward the mating connector in a first direction relatively with respect to the mating connector. The terminals include two terminals arranged on both sides of the inner shield in a second direction perpendicular to the first direction. The inner shield includes a base extending in a third direction perpendicular to the first direction and the second direction, and an extension protruding from the base. The housing includes a shield holder holding the extension. This connector reduces noise propagation between the terminals.

First claim

What is claimed is:

1 . A connector set comprising a first connector and a second connector, wherein
the first connector is configured to be connected to the second connector by moving toward the second connector in a first direction relatively with respect to the second connector, the first connector includes:
a plurality of first terminals;
a first housing holding the plurality of first terminals;
a first outer shield; and
a first inner shield surrounded by the first outer shield,
the second connector includes:
a plurality of second terminals each configured to be electrically connected to a respective one of the plurality of first terminals while the first connector is connected to the second connector;
a second housing holding the plurality of second terminals;
a second outer shield; and
a second inner shield surrounded by the second outer shield,
the first outer shield of the first terminal includes a first outer shield portion and a second outer second shield portion which face each other across a hollow space in a facing direction perpendicular to the first direction, the first outer shield portion includes:
an inner wall facing the hollow space;
an outer wall facing the inner wall across a gap in the facing direction; and
a joining portion connecting the outer wall to the inner wall,
the plurality of first terminals of the first terminal include two first terminals arranged on both sides of the first inner shield of the first terminal in a second direction which is perpendicular to the first direction and which is different from the facing direction, the second inner shield of the second connector is disposed between two second terminals out of the plurality of second terminals, the first inner shield of the first connector includes:
a base extending in the facing direction; and
an extension protruding in the first direction from the base, and
the second outer shield of the second connector is configured to be disposed between the inner wall of the first outer shield portion of the first outer shield of the first connector and the extension of the first inner shield of the first connector while the first connector is connected to the second connector.

2 . The connector set of claim 1 , wherein the base of the first inner shield of the first connector overlaps the inner wall of the first outer shield portion of the first outer shield of the first connector when viewed in the first direction.

3 . The connector set of claim 1 , wherein the second outer shield of the second connector is configured to be disposed between the first inner shield of the first connector and the second inner shield of the second connector while the first connector is connected to the second connector.

4 . The connector set of claim 1 , wherein
the first housing of the first connector includes:
a bottom wall having a first surface and a second surface opposite to the first surface, the first surface being directed in the first direction; and
a peripheral wall protruding in the first direction from the first surface of the bottom wall, the outer shield being fixed to the peripheral wall,
the bottom wall has an accommodation groove therein passing from the first surface to the second surface of the bottom wall, and a part of the first inner shield of the first connector is accommodated in the accommodation groove.

5 . The connector set of claim 1 , wherein the first outer shield of the first connector seamlessly surrounds the plurality of first terminals of the first connector.
