Lever of the lever-fitting-type connector having a locked part with a convex surface
View Patent ↗A lever-fitting-type connector includes a housing having a first terminal and a lever having a second terminal. The housing has a locking projection. The locking projection includes a front inclination surface and a rear inclination surface respectively extending along a sliding direction of the lever, and a ridgeline part where the front and rear inclination surfaces are connected to each other. The lever includes a locked part. The locked part has a convex surface. The convex surface, when the lever slides, moves over the ridgeline part from the front inclination surface toward the rear inclination surface.
1. A lever-fitting-type connector comprising:
a housing including a first terminal; and
a lever including a second terminal, wherein the lever is configured to connect the first terminal to a corresponding main terminal of a partner connector when the lever is in a first position, and to connect the second terminal to a corresponding sub-terminal of the partner connector when the lever slides from a second position to a third position after the lever is rotated by a predetermined angle around the housing from the first position to the second position,
wherein the housing includes a locking projection having a front inclination surface and a rear inclination surface respectively extending along a sliding direction of the lever from the second position toward the third position and a ridgeline part where the front inclination surface and the rear inclination surface are connected to each other,
wherein the lever includes a locked part,
wherein the locked part has a convex surface, and the locked part is configured to move while pressing the convex surface to the locking projection when the lever slides from the second position to the third position, and
wherein the convex surface is configured to move over the ridgeline part from the front inclination surface to the rear inclination surface when the lever reaches the third position.
2. The lever-fitting-type connector according to claim 1 , wherein a length of the front inclination surface in the sliding direction of the lever is longer than a length of the rear inclination surface in the sliding direction of the lever.
3. The lever-fitting-type connector according to claim 1 , wherein the locked part has a shape of a cantilevered beam extending from the lever or a shape of a both-ends supported beam extending from the lever.
4. The lever-fitting-type connector according to claim 2 , wherein the locked part has a shape of a cantilevered beam extending from the lever or a shape of a both-ends supported beam extending from the lever.
