a first upper surface portion extending from an upper edge of the first inner surface portion in the second direction, and a first outer surface portion extending downwardly from the first upper surface portion to face the first inner surface portion,

wherein the second reinforcement portion comprises

a second inner surface portion extending from the base portion toward the center protrusion in the first direction, a second upper surface portion extending from an upper edge of the second inner surface portion in the first direction, and a second outer surface portion extending downwardly from the second upper surface portion to face the second inner surface portion, and

wherein the third reinforcement portion comprises

a third outer surface portion extending from the base portion to face the second inner surface portion in the first direction, and a third upper surface portion extending from an upper edge of the third outer surface portion in the first direction.

5. The receptacle connector of claim 4 ,

wherein the contact piece comprises a fixed end connected to an edge of the base portion in the second direction, and a free end bent upwardly from the fixed end and extending therefrom,

wherein a receiving hole is formed on the first inner surface portion to receive a portion of the contact piece when the contact piece is pressed toward the first outer surface portion in the second direction, and

wherein a receiving recess is formed on the first surrounding portion in the second direction of the receiving hole to be connected with the receiving hole.

6. The receptacle connector of claim 5 ,

wherein the receiving hole is extended up to the first inner surface portion and an inner edge portion contacting the first upper surface portion, and

wherein the inner edge portion comprises an inclined surface downwardly inclining toward the base portion.

7. The receptacle connector of claim 4 ,

wherein the third outer surface portion extends to be inclined with respect to the base portion.

8. The receptacle connector of claim 4 ,

wherein each of the first upper surface portion and the second upper surface portion is arranged to be higher than the third upper surface portion with reference to the base portion.

9. The receptacle connector of claim 4 ,

wherein the receptacle metal member comprises

a first bending portion bent from a lower end of the first outer surface portion toward the first inner surface portion, and a second bending portion bent from a lower end of the second outer surface portion toward the second inner surface portion, and

wherein the first bending portion is arranged to be lower than the base portion, and the second bending portion is arranged to be higher than the base portion.

10. The receptacle connector of claim 9 ,

wherein the receptacle metal member further comprises

a third bending portion bent from a lower end of the first outer surface portion in the opposite direction of the direction facing the first inner surface portion, and a fourth bending portion bent from a lower end of the second outer surface portion in the opposite direction of the direction facing the second inner surface portion, and

wherein the third bending portion and the fourth bending portion are arranged to be lower than the base portion.

11. The receptacle connector of claim 4 ,

wherein the receptacle metal member comprises

one pair of carrier connection portions arranged on both ends of the second upper surface portion in the second direction, and extending from an upper end of the second inner surface portion in the first direction.

12. The receptacle connector of claim 1 ,
