Abstract

A connector includes a lock lever that is fastened to a flat conductor and that maintains electrical connection between a terminal and the flat conductor. The lock lever includes a fastening portion that, in an interior of a fitting chamber, is fastened to the flat conductor that electrically contacts the terminal, and prevents removal of the flat conductor; an elastic portion that displaces the fastening portion in directions towards and away from the flat conductor; and an operation portion that includes a flat plate portion and a connecting portion, the flat plate portion extending along a front wall, the connecting portion extending from the flat plate portion in the direction away from the flat conductor and connected to the elastic portion. The flat plate portion is pushed along an insertion direction of the flat conductor.

First claim

What is claimed is:

1. A connector comprising:
a terminal that electrically contacts a flat conductor serving as an object to be connected;
a housing including an insertion opening for inserting the flat conductor therein, a fitting chamber where the flat conductor and the terminal electrically contact each other, and a side wall portion that forms the fitting chamber; and
a lock lever that is fastened to the flat conductor that is fitted to the terminal, and maintains electrical connection between the terminal and the flat conductor,
wherein the lock lever includes
a fastening portion that, in an interior of the fitting chamber, is fastened to the flat conductor that electrically contacts the terminal, and prevents removal of the flat conductor,
an elastic portion that displaces the fastening portion in directions towards and away from the flat conductor,
an operation portion that includes a flat plate portion and a connecting portion, the flat plate portion extending along the side wall portion, the connecting portion extending from the flat plate portion in the direction away from the flat conductor and connected to the elastic portion, wherein the flat plate portion is pushed along an insertion direction of the flat conductor, so that the connecting portion pushes the elastic portion in the direction away from the flat conductor and the fastening portion is displaced in the direction away from the flat conductor to unfasten the lock lever from the flat conductor, and
a stopper that stops displacement of the operation portion by contacting the housing,

and wherein the flat plate portion of the operation portion is connected to the stopper and the connecting portion.

2. The connector according to claim 1 , wherein the stopper includes a base end portion that is connected to the flat plate portion and connecting portion, the stopper being displaced along with the operation portion and contacting the side wall portion to stop the displacement of the operation portion.

3. The connector according to claim 1 , wherein the side wall portion includes a contact section that the stopper strikes in the insertion direction of the flat conductor.

4. The connector according to claim 1 , wherein the stopper includes an extending portion that extends in a cantilever manner from the operation portion.

5. The connector according to claim 4 , wherein the extending portion is elastically deformed independently of the operation portion.

6. The connector according to claim 1 , wherein the stopper includes a plate edge portion that contacts the side wall portion.

7. The connector according to claim 1 , wherein the side wall portion includes a thick-walled portion that protrudes in a plate thickness direction of the side wall portion and that the stopper contacts.

8. The connector according to claim 7 , wherein the housing includes a plurality of the thick-walled portions, the operation portion is disposed between the thick-walled portions, and an interval between the thick-walled portions is less than a plate width of the flat conductor.

9. The connector according to claim 1 , wherein the operation portion is pushed and displaced so as to approach the side wall portion, and the side wall portion includes a guide surface portion that guides the displacement of the operation portion.

10. The connector according to claim 1 , wherein the operation portion includes a push portion that is connected to the flat plate portion and that is subjected to the pushing, and the push portion is provided at a top surface side of the housing.

11. The connector according to claim 1 , wherein the lock lever includes a housing securing portion that is secured to the housing and a substrate securing portion that is exposed from an opposing side wall portion opposing the side wall portion and that is secured to a substrate.

12. The connector according to claim 1 , wherein the side wall portion includes a leg that contacts a substrate and that supports the housing.

13. The connector according to claim 1 , wherein the lock lever includes a plurality of the fastening portions that are unfastened by operating the operation portion.
