Abstract

There is provided a connector that can decrease a crosstalk generated between facing terminals by a shield plate in a case where at least one of a terminal adjacent to a first ground terminal and a terminal adjacent to a second ground terminal facing the first ground terminal functions as a signal terminal, by forming the shield plate so that one end of the shield plate is coupled to the first ground terminal arranged at each of both ends of one terminal group and the other end of the shield plate is coupled to the second ground terminal arranged at each of both ends of the other terminal group.

First claim

What is claimed is:

1. A connector comprising:
a first terminal group including a plurality of terminals;
a second terminal group including a plurality of terminals;
a first ground terminal;
a second ground terminal;
a housing that is made of insulating resin and that holds the first terminal group, the first ground terminal, the second terminal group, and the second ground terminal;
a shield plate arranged between the first terminal group and the second terminal group; and
a plurality of reinforcing portions arranged at side walls in a short-side direction of the housing,
wherein the plurality of terminals included in the first terminal group are arrayed in a long-side direction of the housing at one side, and the first ground terminal includes a plurality of first ground terminals arranged at both ends with the first terminal group interposed therebetween,
wherein the plurality of terminals included in the second terminal group are arrayed in the long-side direction of the housing at the other side, and the second ground terminal includes a plurality of second ground terminals arranged at both ends with the second terminal group interposed therebetween,
wherein the shield plate is coupled to at least one of the first ground terminals and the second ground terminals via a shield coupling portion,
wherein a reinforcing portion among the plurality of reinforcing portions provided at one of the side walls is coupled to the first ground terminal at one side via a first reinforcing coupling portion,
wherein a reinforcing portion among the plurality of reinforcing portions provided at another one of the side walls is coupled to the second ground terminal at the other side via a second reinforcing coupling portion, and
wherein the first ground terminal and the second ground terminal coupled to the reinforcing portions are not coupled to the shield plate.

2. The connector according to claim 1 ,
wherein a cross-sectional shape of a terminal included in the first terminal group when cut in a short-side direction of the housing is the same as a cross-sectional shape of each of the first ground terminals when cut in the short-side direction, and
wherein a cross-sectional shape of a terminal included in the second terminal group when cut in the short-side direction of the housing is the same as a cross-sectional shape of each of the second ground terminals when cut in the short-side direction.

3. The connector according to claim 1 , wherein the first terminal group, the first ground terminals, the second terminal group, the second ground terminals, the shield plate, and the shield coupling portion are formed by integrally molding with the housing.

4. The connector according to claim 1 , wherein the shield plate includes two shield plates arranged in the long-side direction between the first terminal group and the second terminal group.

5. The connector according to claim 4 , wherein a first shield plate of the two shield plates is coupled to at least one of the first ground terminals, and a second shield plate of the two shield plates is coupled to at least one of the second ground terminals.

6. The connector according to claim 4 , wherein both the two shield plates are coupled to the first ground terminals or the second ground terminals.

7. The connector according to claim 1 , wherein the shield plate is a single shield plate arranged in the long-side direction between the first terminal group and the second terminal group.

8. The connector according to claim 7 , wherein one end of the shield plate is coupled to at least one of the first ground terminals, and the other end of the shield plate is coupled to at least one of the second ground terminals.

9. The connector according to claim 7 , wherein both ends of the shield plate are coupled to the first ground terminals or the second ground terminals.

10. The connector according to claim 1 , wherein the shield plate provides complete separation or partial separation between the plurality of terminals included in the first terminal group and the plurality of terminals included in the second terminal group.

11. The connector according to claim 1 , wherein the shield plate is embedded in a fitting protrusion that is formed at a center portion to extend in the long-side direction of the housing.

12. The connector according to claim 1 , wherein at least one of a terminal adjacent to the first ground terminal arranged at one side and a terminal adjacent to the second ground terminal facing the first ground terminal functions as a signal terminal.

13. The connector according to claim 1 , wherein a terminal adjacent to the first ground terminal arranged at one side functions as a signal terminal, and a terminal adjacent to the second ground terminal facing the first ground terminal functions as a ground terminal.

14. A connector comprising:
a first terminal group including a plurality of terminals;
a second terminal group including a plurality of terminals;
a first ground terminal;
a second ground terminal;
a housing that is made of insulating resin and that holds the first terminal group, the first ground terminal, the second terminal group, and the second ground terminal;
a shield plate arranged between the first terminal group and the second terminal group; and
a reinforcing portion arranged at a side wall in a short-side direction of the housing,
wherein the plurality of terminals included in the first terminal group are arrayed in a long-side direction of the housing at one side, and the first ground terminal includes a plurality of first ground terminals arranged at both ends with the first terminal group interposed therebetween,
wherein the plurality of terminals included in the second terminal group are arrayed in the long-side direction of the housing at the other side, and the second ground terminal includes a plurality of second ground terminals arranged at both ends with the second terminal group interposed therebetween,
wherein the reinforcing portion includes a plurality of reinforcing portions provided at side walls extending in the short-side direction of the housing,
wherein the shield plate is coupled to each of the reinforcing portions via a shield coupling portion,
wherein each of the reinforcing portions is coupled to the first ground terminal and the second ground terminal adjacent to the reinforcing portion, via a reinforcing coupling portion.

15. The connector according to claim 14 ,
wherein a cross-sectional shape of a terminal included in the first terminal group when cut in the short-side direction of the housing is the same as a cross-sectional shape of each of the first ground terminals when cut in the short-side direction, and
wherein a cross-sectional shape of a terminal included in the second terminal group when cut in the short-side direction of the housing is the same as a cross-sectional shape of each of the second ground terminals when cut in the short-side direction.

16. The connector according to claim 14 , wherein the first terminal group, the first ground terminals, the second terminal group, the second ground terminals, the shield plate, the reinforcing portions, and the shield coupling portions are formed by integrally molding with the housing.
