Electrical connector

1. An electrical connector for connection to a complementary electrical connector, the electrical connector comprising:

a housing comprising a column-shaped concavity;

a latch being formed of metal and rotatably carried by the housing, the latch comprising a rotary section having a first curved edge, a second curved edge, and a tab that is received by the concavity, the latch further comprising a lock extending from the rotary section for connection with the complementary electrical connector; and

the housing including an abutment section having a first wall shaped complementarily to the first curved edge and contacting the first curved edge and a second wall shaped complementarily to the second curved edge and contacting the second curved edge, the first and second walls each comprising a shape that lies substantially along circles concentric to a circle about a point within the column-shaped concavity;

wherein the tab has a hook-like shape and is substantially U-shaped at its front end, which abuts on an inner wall of the column-shaped concavity wherein the tab is formed as a portion of the rotary section being sheared and bent.

2. The electrical connector according to claim 1 , wherein the tab is rotatably supported by the concavity.

3. The electrical connector according to claim 1 , wherein a substantial portion of the tab lies substantially parallel to a portion of the rotary section that does not form the tab.

4. The electrical connector according to claim 1 , wherein the concavity is a circular concavity.

5. The electrical connector according to claim 1 , wherein the concavity is a spherical concavity.

6. The electrical connector according to claim 1 , wherein the concavity is a hole.

7. The electrical connector according to claim 1 , the latch further comprising:

a spring extending from the rotary section substantially opposite the lock.

8. The electrical connector according to claim 7 , wherein the spring is biased in a direction substantially orthogonal to a mating direction.

9. The electrical connector according to claim 8 , wherein the lock is biased in a direction substantially opposite to the direction in which the spring is biased.

10. The electrical connector according to claim 1 , further comprising:

a mating plate extending from the housing in a mating direction;

first contacts carried by the mating plate; and

second contacts carried by the mating plate.

11. The electrical connector according to claim 10 , wherein the first contacts and second contacts are arranged in a staggered manner in a row along the mating plate.

12. The electrical connector according to claim 10 , wherein the first contacts and second contacts are positioned on opposing sides of the mating plate.

13. The electrical connector according to claim 10 , wherein the tab is substantially captured within the concavity.
