Lever type connector
View Patent ↗A lever type connector of the present invention includes a connector housing, a cover, a lever rotatably mounted on the connector housing, and a snap tab mounted on the cover. During rotation of the lever from an unlocking position to a locking position, the snap tab is pressed by the lever and bent, and if the lever reaches the locking position, the snap tab is brought back to lock the lever. The maximum bent inward angle of the snap tab is set to be smaller than the outward inclination angle of the snap tab without being bent. It is possible to prevent contact between the snap tab and the electric wires. The electric wires are prevented from being damaged, and the operation failure of the snap tab is also avoided.
1. A lever type connector comprising:
a connector housing to which a terminal having electric wires is attached;
a cover that is mounted on the connector housing to accommodate the electric wires by a given range and lead the electric wires outside;
a lever that is mounted on the connector housing to be rotatable between an unlocking position and a locking position; and
a snap tab provided on the cover, wherein
if the lever is rotated from the unlocking position to the locking position in a state where the partner connector is half-fitted into the connector housing, the partner connector is forcibly displaced from a half-fitted position to a full-fitted position,
the snap tab is pressed by the lever and bent inward of the cover during rotation of the lever from the unlocking position to the locking position so that the lever can rotate, and if the lever reaches the locking position, the snap tab is returned to lock the lever, and
a maximum bent angle of the snap tab bent inward of the cover is set to be smaller than an inclination angle outward of the cover when the snap tab is not bent;
wherein a reinforcing rib that prevents the electric wires from entering a bending region of the snap tab projects from an inner surface of the cover in the vicinity of the snap tab.
2. The lever type connector according to claim 1 , wherein the reinforcing rib is formed to surround the entire periphery of the snap tab.
3. A lever type connector comprising:
a connector housing to which a terminal having electric wires is attached;
a cover that is mounted on the connector housing to accommodate the electric wires by a given range and lead the electric wires outside;
a lever that is mounted on the connector housing to be rotatable between an unlocking position and a locking position; and
a snap tab provided on the cover, wherein
if the lever is rotated from the unlocking position to the locking position in a state where the partner connector is half-fitted into the connector housing, the partner connector is forcibly displaced from a half-fitted position to a full-fitted position,
the snap tab is pressed by the lever and bent inward of the cover during rotation of the lever from the unlocking position to the locking position so that the lever can rotate, and if the lever reaches the locking position, the snap tab is returned to lock the lever, and
a reinforcing rib that prevents the electric wires from entering a bending region of the snap tab projects from an inner surface of the cover in the vicinity of the snap tab, and other reinforcing rib projects from the inner surface of the cover at a position other than the periphery of the snap tab.
4. The lever type connector according to claim 3 , wherein each reinforcing rib is provided in a form of a lattice.
5. The lever type connector according to claim 3 , wherein the reinforcing rib other than the other reinforcing rib is formed to surround the entire periphery of the snap tab.
