Lock release mechanism using pull-tab and connector having the lock release mechanism

1. A lock release mechanism for releasing an engagement of a body component with a counterpart member by moving a lock mechanism engaging with said counterpart member, said lock release mechanism comprising:

a lock lever connected to said lock mechanism;

a pivot axle connecting said lock lever to said body component so that said lock lever is pivotable relative to said body component; and

a flexible pull-tab connected to said lock lever, said lock mechanism being moved in accordance with pivoting of said lock lever caused by a force pulling said pull-tab, thereby to release the engagement with said counterpart member.

2. The lock release mechanism according to claim 1 , wherein a direction of the force pulling said pull-tab is designed to coincide with a direction in which said lock mechanism is detached from said counterpart member.

3. The lock release mechanism according to claim 1 , wherein a direction of the force pulling said pull-tab is designed to differ from a direction in which said lock mechanism is detached from said counterpart member.

4. The lock release mechanism according to claim 1 , wherein said lock mechanism is formed integral with said body component attached to said counterpart member, said lock mechanism being movable relative to said body component.

5. The lock release mechanism according to claim 4 , wherein said body component is designed so as to be detached from said counterpart member in a first direction, said lock mechanism being movable in a second direction perpendicular to said first direction, said pull-tab being designed so as to be pulled in said first direction.

6. The lock release mechanism according to claim 4 , wherein said body component is designed so as to be detached from said counterpart member in a first direction, said lock mechanism being movable in a second direction perpendicular to said first direction, said pull-tab being designed so as to be pulled in a third direction parallel to and opposite to said second direction.

7. The lock release mechanism according to claim 1 , wherein said lock mechanism is a member separated from said body component confronting said counterpart member, said lock mechanism being attached movably to said body component, said pull-tab being connected to said lock mechanism.

8. The lock release mechanism according to claim 7 , wherein said lock mechanism is attached pivotably to said body component.

9. The lock release mechanism according to claim 8 , wherein said lock mechanism is rotated by the force pulling said pull-tab, thereby to release the engagement with said counterpart member.

10. The lock release mechanism according to claim 7 , wherein said lock mechanism is attached slidably to said body component.

11. The lock release mechanism according to claim 10 , wherein said lock mechanism slides by the force pulling said pull-tab, thereby to release the engagement with said counterpart member.

12. The lock release mechanism according to claim 1 , wherein said pull-tab has a semicircular shape.

13. The lock release mechanism according to claim 1 , wherein said pull-tab is formed integral with said lock mechanism.

14. The lock release mechanism according to claim 1 , wherein said pull-tab is formed separately from said lock mechanism.

15. The lock release mechanism according to claim 14 , wherein said pull-tab is fixed to said lock mechanism by soldering.

16. The lock release mechanism according to claim 14 , wherein said pull-tab is fixed to said lock mechanism by caulking.

17. The lock release mechanism according to claim 14 , wherein said pull-tab is fixed to said lock mechanism by hooking.

18. The lock release mechanism according to claim 1 , wherein said pull-tab is pivotably connected to said lock mechanism.

19. The lock release mechanism according to claim 18 , wherein said lock mechanism comprises a lock lever retained pivotably about a pivot axis, and the pivot axis of said lock lever and a pivot axis of said pull-tab are eccentric to each other in a direction perpendicular to an engaging direction of said lock mechanism.

20. The lock release mechanism according to claim 18 , further comprising a tab portion slidably arranged on said pull-tab.

21. A lock release mechanism for releasing an engagement of a body component with a counterpart member by moving two movable lock mechanisms engaging with said counterpart member, said lock release mechanism comprising:

a pair of lock levers connected to said lock mechanisms, respectively;

a pair of pivot axles connecting said lock levers to said body component, respectively, so that said lock levers are pivotable relative to said body component; and

a pull-tab in the form of a flexible elongate member having both ends connected to said two lock mechanisms, respectively, said lock mechanisms being moved in accordance with pivoting of said lock levers caused by components of a force pulling said pull-tab, thereby to release the engagement with said counterpart member.

22. The lock release mechanism according to claim 21 , wherein a direction of the force pulling said pull-tab is designed to coincide with a direction in which at least one of said lock mechanisms is detached from said counterpart member.

23. A connector comprising:

a connector body for connecting to a counterpart connector;

a mechanism connected to said connector body for engaging with said counterpart connector, said mechanism serving as the lock mechanism described in claim 1 ; and

the lock release mechanism.

24. A lock release mechanism for releasing an engagement of a body component with a counterpart member by moving a lock mechanism engaging with said counterpart member, said lock release mechanism comprising:

a lock lever connected to said lock mechanism;

a pivot axle connecting said lock lever to said body component so that said lock lever is pivotable relative to said body component;

a pull-tab pivotally connected to said lock mechanism; and

a tab portion slidably arranged on said pull-tab wherein said pull tab is connected to said lock lever, said lock mechanism being moved in accordance with pivoting of said lock lever caused by a force pulling said pull-tab, thereby to release the engagement with said counterpart member.
