[0002]

2. Description of the Related Art When the number of terminals built in increases due to the increase in the number of terminals in a connector, a large force is required for insertion or removal of the connector due to the contact resistance (fitting force) between the female and male terminals. Work becomes difficult. Therefore,
A lever having a cam groove is rotatably provided on one of the pair of connectors, and a cam pin is provided on the other for engaging with the cam groove. The lever action of the lever reduces the force required for normal insertion of the female and male terminals. In addition, there is used one in which both connectors can be fitted with much smaller force.

FIG. 10 is an exploded perspective view of a first conventional example.
Bosses a ₁ , a ₁ into which the fulcrum holes b ₁ of the lever b are inserted on both side surfaces of the female connector a and locking projections a ₂ , a ₂ for the lever b

It is an object to provide an attached connector. In the second conventional example, the built-in spring is required as a separate part, which not only costs parts and assembly but also makes it difficult to work because the lever moves upward from the operator's hand when the connector is engaged or disengaged. There was a problem.

In view of the above, the second embodiment of the present invention holds the lever of the female connector in the provisionally locked state in the provisionally locked state, and maintains the lever in the fully locked state in which both connectors are fitted. An object of the present invention is to provide a connector with a lever having a structure capable of holding a stopped state. In the third conventional example, the male connector is divided into a plurality of connectors without interruption due to the gradual decrease in the operation force of fitting and disengagement, thereby deteriorating the work efficiency, and the so-called half where the female and male connectors are not completely fitted. There has been a problem that it is difficult to find the state of the fitting at a glance.
