Abstract

A plurality of upper plug contacts are each brought into contact with a master elastic piece and a slave elastic piece of a corresponding lower receptacle contact in accordance with elastic deformation of the master elastic piece and the slave elastic piece. A plurality of lower plug contacts are each brought into contact with a master elastic piece and a slave elastic piece of a corresponding upper receptacle contact in accordance with elastic deformation of the master elastic piece and the slave elastic piece. For example, as shown in FIG. 7 , in a state where an upper connector and a lower connector are mated, a direction of the elastic deformation of the master elastic piece and the slave elastic piece of each upper receptacle contact is different from a direction of the elastic deformation of the master elastic piece and the slave elastic piece of each lower receptacle contact.

First claim

What is claimed is:

1. A connector assembly comprising:
a first connector including a plurality of first plug contacts and a plurality of first receptacle contacts each having a first elastic piece, the plurality of first plug contacts and the plurality of first receptacle contacts being alternately arranged in a grid array; and
a second connector including a plurality of second plug contacts and a plurality of second receptacle contacts each having a second elastic piece, the plurality of second plug contacts and the plurality of second receptacle contacts being alternately arranged in a grid array, wherein
the plurality of first plug contacts are each brought into contact with the second elastic piece of the corresponding second receptacle contact in accordance with elastic deformation of the second elastic piece,
the plurality of second plug contacts are each brought into contact with the first elastic piece of the corresponding first receptacle contact in accordance with elastic deformation of the first elastic piece, and
a direction of the elastic deformation of the first elastic piece is different from a direction of the elastic deformation of the second elastic piece in a state in which the first connector and the second connector are mated, and in the state in which the first connector and the second connector are mated, the first elastic piece is elastically deformed in a direction perpendicular to a thickness direction of the first receptacle contacts, and the second elastic piece is elastically deformed in a direction perpendicular to a thickness direction of the second receptacle contacts.

2. The connector assembly according to claim 1 , wherein in the state in which the first connector and the second connector are mated, the direction of the elastic deformation of the first elastic piece is different from the direction of the elastic deformation of the second elastic piece by about 90 degrees.

3. The connector assembly according to claim 1 , wherein a plate thickness of each of the first plug contacts is the same as a plate thickness of each of the first receptacle contacts.

4. The connector assembly according to claim 1 , wherein a planar shape of each of the first plug contacts is the same as a planar shape of each of the second plug contacts, and a planar shape of each of the first receptacle contacts is the same as a planar shape of each of the second receptacle contacts.

5. The connector assembly according to claim 1 , wherein the first plug contact and the second plug contact are each formed into a flat plate shape.

6. The connector assembly according to claim 5 , wherein a thickness direction of the first plug contacts is the same as a thickness direction of the first receptacle contacts adjacent to the first plug contacts in a direction perpendicular to the thickness direction of the first plug contacts.

7. The connector assembly according to claim 6 , wherein the first plug contacts are each formed in such a manner that the first plug contacts are each narrowed at a leading end thereof, the leading end projecting toward the second connector.

8. The connector assembly according to claim 6 , further comprising a plurality of first housing divided bodies, wherein
each of the first housing divided bodies holds the plurality of first plug contacts and the plurality of first receptacle contacts that are alternately arranged in the direction perpendicular to the thickness direction of the first plug contacts.

9. The connector assembly according to claim 8 , wherein each of the first housing divided bodies comprises two holding members that hold the plurality of first plug contacts and the plurality of first receptacle contacts by sandwiching the plurality of first plug contacts and the plurality of first receptacle contacts in the thickness direction of the first plug contacts, the first plug contacts and the first receptacle contacts being alternately arranged in the direction perpendicular to the thickness direction of the first plug contacts.

10. The connector assembly according to claim 1 , wherein each of the first receptacle contacts has two first elastic pieces, and the two first elastic pieces have different shapes.

11. The connector assembly according to claim 10 , wherein any one of the plurality of first receptacle contacts is reversely positioned with respect to the other first receptacle contacts.

12. A connector assembly comprising:
a first connector including a plurality of first plug contacts and a plurality of first receptacle contacts each having a first elastic piece, the plurality of first plug contacts and the plurality of first receptacle contacts being alternately arranged in a grid array; and
a second connector including a plurality of second plug contacts and a plurality of second receptacle contacts each having a second elastic piece, the plurality of second plug contacts and the plurality of second receptacle contacts being alternately arranged in a grid array, wherein
the plurality of first plug contacts are each brought into contact with the second elastic piece of the corresponding second receptacle contact in accordance with elastic deformation of the second elastic piece,
the plurality of second plug contacts are each brought into contact with the first elastic piece of the corresponding first receptacle contact in accordance with elastic deformation of the first elastic piece,
a direction of the elastic deformation of the first elastic piece is different from a direction of the elastic deformation of the second elastic piece in a state in which the first connector and the second connector are mated, and
a thickness direction of the first plug contacts is the same as a thickness direction of the first receptacle contacts adjacent to the first plug contacts in a direction perpendicular to the thickness direction of the first plug contacts.
