Abstract

A receptacle connector 10 includes a ground contact 11 including a fitting portion 11a that has a tubular shape and is to be fitted to a ground contact 101 of a plug connector 100; a signal contact 12 that is to be electrically connected to a signal contact 102 of the plug connector 100; and an insulating housing 13 that holds the ground contact 11 and the signal contact 12 in an insulated state. The signal contact 12 includes a central conductor 12a, and a board connection portion 12b that extends so as to lead out from the central conductor 12a to be connected to a signal terminal portion 201 of the board 200. The board connection portion 12b is accommodated in a region surrounded by the fitting portion 11a, and at least a part of the board connection portion 12b is exposed to an outside.

First claim

1 . An electrical connector mounted on a board, the connector comprising:
a first contact configured to have a tubular shape and be fitted to a ground contact of a mating connector; a second contact configured to be electrically connected to a signal contact of the mating connector; and a first insulating housing configured to hold the first contact and the second contact in an insulated state, wherein the second contact comprises:
a central conductor configured to come into contact with the signal contact of the mating connector; and
a board connection portion configured to extend so as to lead out from the central conductor to be connected to a terminal portion of the board, and
wherein the board connection portion is accommodated in a region surrounded by the first contact, and comprises an exposed portion which is at least a part of the board connection portion and is exposed to an outside.

2 . The electrical connector according to claim 1 ,
wherein the board connection portion is disposed such that the exposed portion is visible when viewed in a Z direction, and wherein the Z direction is a direction of fitting the electrical connector to the mating connector and is a direction from the mating connector toward the board.

3 . The electrical connector according to claim 1 ,
wherein the exposed portion is a tip portion of the board connection portion in an X direction, and wherein the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board.

4 . The electrical connector according to claim 1 ,
wherein the first insulating housing comprises a cutout portion which exposes the exposed portion to the outside.

5 . The electrical connector according to claim 4 ,
wherein the cutout portion is formed such that a region of contact with the terminal portion on the board connection portion is exposed to the outside.

6 . The electrical connector according to claim 4 ,
wherein the first insulating housing is not cut out in a first region that is closer to the central conductor than the exposed portion of the board connection portion in an X direction, wherein the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board, and wherein the first insulating housing is cut out in a second region that is not closer to the central conductor than the exposed portion of the board connection portion in the X direction.

7 . The electrical connector according to claim 6 ,
wherein at least a part of the first insulating housing is not cut out in a region in the second region located outside both end portions of the exposed portion in a Y direction, and wherein the Y direction is a direction crossing the X direction.

8 . The electrical connector according to claim 4 ,
wherein a length in a Y direction of the cutout portion is longer than a length in the Y direction of the exposed portion, and wherein the Y direction is a direction crossing an X direction and the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board.

9 . The electrical connector according to claim 4 ,
wherein a length in a Y direction of the cutout portion is longer than a length in the Y direction of the terminal portion of the board, and wherein the Y direction is a direction crossing an X direction and the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board.

10 . The electrical connector according to claim 1 ,
wherein the first insulating housing is provided at least in a first region that is closer to the central conductor than the exposed portion of the board connection portion in an X direction, wherein the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board, and wherein the first insulating housing is not provided in a second region that is not closer to the central conductor than the exposed portion of the board connection portion in the X direction.

11 . The electrical connector according to claim 10 ,
wherein the first insulating housing has a circular shape including a major segment.

12 . The electrical connector according to claim 10 ,
wherein the second region has a circular shape including a minor segment.

13 . A connector device comprising:
a first connector mounted on a board; and a second connector configured to be connected to a signal transmission member and be fitted to the first connector, wherein the first connector comprises:
a first contact configured to be a ground contact having a tubular shape;
a second contact configured to be a signal contact; and
a first insulating housing configured to hold the first contact and the second contact in an insulated state,
wherein the second connector comprises:
a third contact configured to have a tubular shape and be fitted to the first contact;
a fourth contact configured to be electrically connected to the second contact; and
a second insulating housing configured to hold the third contact and the fourth contact in an insulated state,
wherein the second contact comprises:
a central conductor configured to come into contact with the fourth contact; and
a board connection portion configured to extend so as to lead out from the central conductor to be connected to a terminal portion of the board,
wherein in a state where the first connector and the second connector are fitted to each other, the board connection portion is accommodated in a region surrounded by the third contact of the second connector, and wherein in a state where the first connector and the second connector are not fitted to each other, at least a part of the board connection portion is exposed to an outside.

14 . The electrical connector according to claim 13 ,
wherein at least a part of the board connection portion is not accommodated in a region surrounded by the first contact of the first connector, and the part of the board connection portion extends to an outside of the first contact.

15 . The electrical connector according to claim 13 ,
wherein an outer end of the third contact of the second connector is disposed outside an outer end of the first contact of the first connector in an X direction, and wherein the X direction is an extending direction of the board connection portion from the central conductor toward the terminal portion of the board, and wherein a tip of the board connection portion is located between the outer end of the first contact of the first connector in the X direction and the outer end of the third contact of the second connector in the X direction.

16 . An electrical connector configured to be connected to a signal transmission member and fitted to mating connector mounted on a board, the connector comprising:
