Abstract

In a board-to-board connector assembly, a plug-side power contact includes a first flat surface portion having a plate-like shape, a second flat surface portion having a plate-like shape and being opposed to a first part of the first flat surface portion and a power-contact-side connection portion connecting the first and second flat surface portions to each other. The first flat surface portion has the first part facing in parallel to the second flat surface portion and a second part or an upper end portion other than the first part. The first part includes a thinned portion having a shape recessed more deeply than a surface of the upper end portion and having a smaller thickness along the third direction than a thickness of the upper end portion.

First claim

What is claimed is:

1. A board-to-board connector assembly, comprising:
a receptacle connector comprising:
a receptacle-side housing comprising:
an insular portion having long sides along a first direction and extending along a second direction orthogonal to the first direction; and
receptacle-side long wall portions formed so that a recessed portion is formed between the insular portion and each of the receptacle-side long wall portions along a third direction orthogonal to both of the first direction and the second direction;

a receptacle-side signal contact comprising a contact portion, the receptacle-side signal contact being retained in the receptacle-side housing so that the contact portion is exposed to an inside of the recessed portion; and
a receptacle-side power contact, which is retained in the receptacle-side housing so as to be arrayed together with the receptacle-side signal contact along the first direction; and

a plug connector comprising:
a plug-side housing comprising a projecting portion to be inserted into the recessed portion;
a plug-side signal contact, which is retained in the plug-side housing so as to be exposed to an outside of the projecting portion; and
a plug-side power contact, which is retained in the plug-side housing so as to be exposed to the outside of the projecting portion, and is to be brought into contact with the receptacle-side power contact,
the plug-side power contact comprising:
a first flat surface portion having a plate-like shape and being parallel to the first direction and the second direction;
a second flat surface portion having a plate-like shape and being opposed to a part of the first flat surface portion through intermediation of a component of the plug-side housing; and
a power-contact-side connection portion formed in parallel to the third direction and the first direction and configured to connect the first flat surface portion and the second flat surface portion to each other,

at least one of the first flat surface portion and the second flat surface portion comprising:
a stepped portion between a surface opposed in parallel to a surface of another one of the first flat surface portion and the second flat surface portion, and a surface except for the surface opposed in parallel to the surface of the another one of the first flat surface portion and the second flat surface portion; and
a thinned portion that corresponds to a portion having the surface opposed in parallel to the surface of the another one of the first flat surface portion and the second flat surface portion, and has a smaller thickness along the third direction than a thickness of a portion having the surface except for the surface opposed in parallel to the surface of the another one of the first flat surface portion and the second flat surface portion.

2. A board-to-board connector assembly according to claim 1 ,
wherein the plug-side signal contact comprises:
a third flat surface portion having a plate-like shape and being parallel to the first direction and the second direction;
a fourth flat surface portion having a plate-like shape and being opposed to a part of the third flat surface portion through intermediation of the component of the plug-side housing; and
a signal-contact-side connection portion formed in parallel to the third direction and the first direction and configured to connect the third flat surface portion and the fourth flat surface portion to each other, and

wherein a distance along the third direction between an inner side of the third flat surface portion and an inner side of the fourth flat surface portion is equal to a distance along the third direction between the first flat surface portion and the second flat surface portion at a position between an inner side of the thinned portion and an inner side of one of the first flat surface portion and the second flat surface portion opposed to the thinned portion.

3. A board-to-board connector assembly according to claim 1 ,
wherein the plug-side power contact is arranged on an end portion side of the plug-side housing along the first direction with respect to the plug-side signal contact, and
wherein the receptacle-side power contact is arranged on an end portion side of the receptacle-side housing along the first direction with respect to the receptacle-side signal contact.

4. A board-to-board connector assembly according to claim 1 ,
wherein the plug-side housing further comprises a plug-side reinforcing portion arranged on the end portion side of the plug-side housing along the first direction with respect to the plug-side power contact, and
wherein the receptacle-side housing further comprises a receptacle-side reinforcing portion arranged on the end portion side of the receptacle-side housing along the first direction with respect to the receptacle-side power contact.

5. A board-to-board connector assembly according to claim 4 , wherein the plug-side reinforcing portion and the receptacle-side reinforcing portion are to be used for conduction of power through contact with each other under a state in which the plug connector and the receptacle connector are fitted to each other.

6. A board-to-board connector assembly according to claim 4 ,
wherein the plug-side reinforcing portion is arranged on each end of the plug-side housing along the first direction, and
wherein the receptacle-side reinforcing portion is arranged on each end of the receptacle-side housing along the first direction.

7. A board-to-board connector assembly according to claim 1 ,
wherein the plug-side power contacts equally arranged at four positions on the plug-side housing, and
wherein the receptacle-side power contacts are equally arranged at four positions on the receptacle-side housing.

8. A board-to-board connector assembly according to claim 1 ,
wherein the plug-side power contact is wider than the plug-side signal contact along the first direction, and
wherein the receptacle-side power contact is wider than the receptacle-side signal contact along the first direction.

9. A connector, comprising:
a plug-side housing, which has long sides along a first direction, the plug-side housing comprising a plug-side fitting portion extending along a second direction orthogonal to the first direction;
a plug-side signal contact, which is retained in the plug-side housing so as to be exposed to an outside of the plug-side fitting portion; and
a plug-side power contact, which is retained in the plug-side housing so as to be exposed to the outside of the plug-side fitting portion,
the plug-side power contact comprising:
a first flat surface portion having a plate-like shape and being parallel to the first direction and the second direction;
a second flat surface portion having a plate-like shape and being opposed to a part of the first flat surface portion through intermediation of a component of the plug-side housing; and
a power-contact-side connection portion formed in parallel to the first direction and a third direction orthogonal to the first direction and the second direction, and configured to connect the first flat surface portion and the second flat surface portion to each other,

at least one of the first flat surface portion and the second flat surface portion comprising:
a stepped portion between a surface opposed in parallel to a surface of another one of the first flat surface portion and the second flat surface portion, and a surface except for the surface opposed in parallel to the surface of the another one of the first flat surface portion and the second flat surface portion; and
a thinned portion that corresponds to a portion having the surface opposed in parallel to the surface of the another one
