Board-to-board connector

1. A board-to-board connector pair, comprising:

a first connector, the first connector including including:

a first housing of a substantially rectangular shape, the first housing including a pair of spaced apart first sidewalls defining an elongated insertion receptacle with a central projection therein, a plurality of first terminal receiving cavities, each first terminal receiving cavity being spaced along the first housing, and a first lock receiving cavity at each end of the first housing,

a plurality of first terminals, each first terminal being mounted in a respective first terminal receiving cavity, and

a first reinforcing locking bracket, the first reinforcing locking bracket being mounted in each first lock receiving cavities; and

a second connector, the second connector being adapted for mating with the first connector and including:

a second housing of a substantially rectangular shape, the second housing including a pair of spaced apart second sidewalls defining an elongated channel therebetween, the elongated channel being configured to receive the central projection therein, a plurality of second terminal receiving cavities, each second terminal receiving cavity being spaced along the second housing, and a second lock receiving cavity at each end of the second housing,

a plurality of second terminals, each second terminal being mounted in a respective second terminal receiving cavity and being configured to operatively mate with one of the first terminals, and

a second reinforcing locking bracket, the second reinforcing locking bracket being mounted in each second lock receiving cavities;

wherein:

the first reinforcing locking brackets are planar members stamped from sheet metal and include a pair of first body parts, each first body part including a deflectable first locking arm and a first board mounting part for mounting to a first circuit member and being positioned on opposite sides of the insertion receptacle and secured to one of the sidewalls, and a relatively narrow and deflectable connecting member interconnecting the first body parts; and

the second reinforcing locking brackets are planar members stamped from sheet metal and include a pair of locking parts, a bracket retention section for securing the second locking bracket to the second housing, and a second board mounting part for mounting to a second circuit member, each locking part being configured to lockingly engage one of the first locking arms to assist in securing the first and second connectors together.

2. The board-to-board connector pair according to claim 1 , wherein the connecting member includes at least one projecting portion extending downward from an edge thereof.

3. The board-to-board connector pair according to claim 1 , wherein the connecting member includes at least two spaced apart projecting portions extending downward from a lower edge thereof.

4. The board-to-board connector pair according to claim 1 , wherein each first body part further includes a first retention part connected to one end of the first mounting part.

5. The board-to-board connector pair according to claim 4 , wherein the retention part and a portion of the first locking arm engage opposite sides of one of the first sidewalls.

6. The board-to-board connector pair according to claim 5 , wherein the first retention part and the portion of the first locking arm that engage opposite sides of one of the first sidewalls does so at a location spaced inwardly from an outside edge of the first sidewall.

7. The board-to-board connector pair according to claim 5 , wherein the first retention part includes a holding projection protruding in a direction toward one of the locking parts.

8. The board-to-board connector pair according to claim 7 , wherein one of the locking parts includes a lock projection protruding in a direction toward the first retention part.

9. The board-to-board connector pair according to claim 8 , wherein the first locking arm engages the other locking part.

10. The board-to-board connector pair according to claim 9 , wherein one of the locking parts further includes a first engaging projection formed at a position closer to a free end thereof than the lock projection.

11. The board-to-board connector pair according to claim 10 , wherein such first engaging projection protrudes in a direction opposite the holding projection, and is engaged with one of the second locking brackets.

12. The board-to-board connector pair according to claim 1 , wherein each of the first and second connectors has a longitudinal axis.

13. The board-to-board connector pair according to claim 12 , wherein the first and second reinforcing locking brackets mate together in a plane having a thickness as thick as the sheet metal from which the first and second reinforcing locking brackets are stamped.

14. The board-to-board connector pair according to claim 12 , wherein each of the first and second reinforcing locking brackets have a thickness along the longitudinal axis, the thickness being as thick as the sheet metal from which the first and second reinforcing locking brackets are stamped.

15. The board-to-board connector pair according to claim 1 , wherein each first terminal is spaced along the insertion receptacle.

16. The board-to-board connector pair according to claim 15 , wherein each second terminal is spaced along the channel.

17. The board-to-board connector pair according to claim 1 , wherein each locking part includes a deflectable arm.

18. The board-to-board connector pair according to claim 17 , wherein the bracket retention section extends through a central bore between the sidewalls of the second connector.
