Abstract

A connector assembly is disclosed including a first connector and a second connector matable with the first connector. The first connector has a first housing, a first power terminal attached, and a first signal terminal. The second connector has a lever attached to a moving housing, the lever moving the moving housing between a mating released position, an intermediate position, and a mating completed position, a second housing movably disposed within the moving housing, a second power terminal disposed in the second housing and contacting the first power terminal in the intermediate position, a second signal terminal attached to the moving housing and contacting the first signal terminal at a position between the intermediate position and the mating completed position, and a separating protrusion disposed on the moving housing preventing the second power terminal from contacting the first power terminal in the mating released position.

First claim

What is claimed is:

1. A connector assembly, comprising:
a first connector having a first housing, a first power terminal attached to the first housing, and a first signal terminal attached to the first housing; and
a second connector matable with the first connector, the second connector having:

a lever attached to a moving housing, the lever moving the moving housing between a mating released position, an intermediate position, and a mating completed position;
a second housing movably disposed within the moving housing, the second housing inserted into the first housing in the mating released position;
a second power terminal disposed in the second housing and contacting the first power terminal in the intermediate position;
a second signal terminal attached to the moving housing and contacting the first signal terminal at a position between the intermediate position and the mating completed position; and
a separating protrusion disposed on the moving housing preventing the second power terminal from contacting the first power terminal in the mating released position.

2. The connector assembly of claim 1 , wherein the lever rotates between a lever mating released position locating the moving housing at the mating released position, a lever intermediate position locating the moving housing at the intermediate position, and a lever mating completed position locating the moving housing at the mating completed position.

3. The connector assembly of claim 2 , wherein a time lag lock mechanism is disposed on the first housing and the lever.

4. The connector assembly of claim 3 , wherein, when the lever is located at the lever intermediate position, the time lag lock mechanism is capable of locking and releasing rotation of the lever.

5. The connector assembly of claim 4 , wherein the time lag lock mechanism has a time lag projection disposed on the first housing and a time lag lock arm disposed on the lever including an engagement portion engaging with the time lag projection.

6. The connector assembly of claim 5 , wherein the time lag lock arm has a central support portion attached to the lever.

7. The connector assembly of claim 6 , wherein the time lag lock arm is tiltably disposed on the lever.

8. The connector assembly of claim 7 , wherein the time lag lock arm has an engagement portion disposed on a first side of the support portion and a pressing operation portion disposed on a second side of the support portion.

9. The connector assembly of claim 1 , wherein the first power terminal is a tab terminal, and the second power terminal has a pair of elastic contact arms receiving and contacting the tab terminal between the pair of elastic contact arms.

10. The connector assembly of claim 9 , wherein the separating protrusion has a width greater than a thickness of the tab terminal.

11. The connector assembly of claim 10 , wherein, in the mating released position, the separating protrusion is disposed between the pair of elastic contact arms and separates the pair of elastic contact arms.

12. The connector assembly of claim 11 , wherein, while the moving housing is moved from the mating released position to the intermediate position, the separating protrusion is withdrawn from between the pair of elastic contact arms.

13. The connector assembly of claim 1 , wherein movement of the second housing is restricted by the first housing when the second housing is inserted into the first housing.

14. The connector assembly of claim 13 , wherein the first housing has a second housing lock portion restricting movement of the second housing in a direction opposite an insertion direction.

15. The connector assembly of claim 14 , wherein the lever has an unlock portion releasing the second housing from the second housing lock portion.
