## Abstract

A board-to-board connector comprises a first connector (1) and a second connector (101). The first connector has first terminals (61) and a first housing (11), which has a generally rectangular parallelepiped shape. The first housing is provided with concave insertion portions and first reinforcing brackets (51), which are arranged in the concave insertion portions. The second connector has second terminals (161) configured to make contact with the first terminals, and a second housing (111) which has a generally rectangular parallelepiped shape. The second housing is provided with convex insertion portions (122) configured to be inserted in the concave insertion portions, and second reinforcing brackets (151) arranged in the convex insertion portions and configured to engage with the first reinforcing brackets.

## Claims

### Claim 1

A board-to-board connector comprising:
a first connector, the first connector including first terminals, a first housing having a generally rectangular parallelepiped shape and provided with concave insertion portions, and first reinforcing brackets arranged in the concave insertion portions, each first reinforcing bracket being provided with a first protrusive locking portion, the first locking portion having an outer surface, one half of which is configured as a curved surface having a small radius of curvature, and the other half being configured as a curved surface having a larger radius of curvature or a sloped flat surface; and
a second connector, the second connector including second terminals configured to make contact with the first terminals, a second housing having a generally rectangular parallelepiped shape and provided with convex insertion portions configured fit within the concave insertion portions, and second reinforcing brackets arranged in the convex insertion portions and configured to engage the first reinforcing brackets, each second reinforcing bracket being provided with a second protrusive locking portion configured to engage the first locking portion, the second locking portion having an outer surface, one half of which is configured as a curved surface having a small radius of curvature, and the other half being configured as a curved surface having a larger radius of curvature or a sloped flat surface, both halves being curved or sloped in the same direction;
wherein one of the first reinforcing bracket and the second reinforcing bracket is formed of a large-width member, and the other is formed of a small-width member.

### Claim 2 (depends on 1)

The board-to-board connector of claim 1, wherein the reinforcing brackets formed of the large-width member include a folded portion formed by folding a thick plate having a large width twice.

### Claim 3 (depends on 1)

The board-to-board connector of claim 1, wherein the concave insertion portions are formed at both ends in a longitudinal direction of the first housing.

### Claim 4 (depends on 1)

The board-to-board connector of claim 1, wherein each first reinforcing bracket is provided with a first connecting arm portion formed by folding a thick plate having a large width.

### Claim 5 (depends on 3)

The board-to-board connector of claim 3, wherein the first reinforcing brackets are arranged on both sides of each concave insertion portion.

### Claim 6 (depends on 5)

The board-to-board connector of claim 5, wherein the convex insertion portions are formed at both ends in the longitudinal direction of the second housing.

### Claim 7 (depends on 6)

The board-to-board connector of claim 6, wherein the second reinforcing brackets are arranged in each convex insertion portion.

### Claim 8 (depends on 4)

The board-to-board connector of claim 4, wherein the first connecting arm portion is provided with a first locking portion formed in a bent portion.
