Abstract

Provided is a board-to-board connector including a housing having a protrusion, one or more signal terminals held on the housing such that a contact portion is exposed to the side of the protrusion, a high-frequency signal terminal arranged outside an end portion of the protrusion, and a shell surrounding an outer peripheral portion of the housing and made of a conductive metal material. In the board-to-board connector, the shell integrally includes a GND terminal portion having a plate-shaped board-side shielding portion arranged on a bottom portion outside the end portion of the protrusion and a plate-shaped GND terminal body standing on the protrusion-side end of the board-side shielding portion and arranged closer to the protrusion with respect to the high-frequency signal terminal, and a high-frequency signal terminal housing hole in which the high-frequency signal terminal is arranged is formed in the board-side shielding portion.

First claim

What is claimed is:

1 . A board-to-board connector comprising: a housing having a protrusion; one or more signal terminals held on the housing such that a contact portion is exposed to a side of the protrusion; a high-frequency signal terminal arranged outside an end portion of the protrusion; and a shell surrounding an outer peripheral portion of the housing and made of a conductive metal material,
wherein the shell integrally includes a GND terminal portion having a plate-shaped board-side shielding portion arranged on a bottom portion outside the end portion of the protrusion and a plate-shaped GND terminal body standing on a protrusion-side end of the board-side shielding portion and arranged closer to the protrusion with respect to the high-frequency signal terminal, wherein the board-side shielding portion is formed with a board mounting portion exposed to the board side of the housing, extending diagonally from an inner edge of the board mounting portion towards the protrusion side to form a terminal body supporting portion, with a lower end of the GND terminal body supported at a tip of the terminal body supporting portion, and a high-frequency signal terminal housing hole is formed along the inner side of the terminal body supporting portion and the board mounting portion, with the high-frequency signal terminal arranged inside the high-frequency signal terminal housing hole.

2 . The board-to-board connector according to claim 1 , wherein the GND terminal portion integrally includes a reinforcing piece bent toward the protrusion from an upper edge of the GND terminal body.

3 . The board-to-board connector according to claim 1 , wherein the GND terminal body is formed with a length with which an upper end thereof reaches a top surface of the protrusion, and an end surface of the protrusion is covered with the GND terminal body.

4 . The board-to-board connector according to claim 2 , wherein a partner connector includes a partner GND terminal exposed at a portion facing an end surface of the protrusion and made of a conductive metal material, and the partner GND terminal contacts the GND terminal body.

5 . The board-to-board connector according to claim 1 , wherein a partner connector includes a partner high-frequency signal terminal that comes into contact with the high-frequency signal terminal, the partner high-frequency signal terminal has a connection groove formed by punching a conductive metal plate material, and the high-frequency signal terminal is inserted into the connection groove with plate thickness directions thereof perpendicular to each other and accordingly contacts a cut surface formed as an inner surface of the connection groove.
