However, in the conventional connector, the pull-out lever 4 is used only when the plug connector 1 is pulled out. When the plug connector 2 is fitted to the receptacle connector 1, the plug-in lever 4 is not used. Since the connector 2 is directly pushed in by hand or pushed in using a jig or the like, the operability at the time of fitting connection is extremely poor.

In the conventional connector, the extraction levers 4 are provided independently at both ends of the plug housing 3 and have no relevance to each other even in the extraction operation. If the same force is not applied to the lever 4, the plug housing 3 will be slanted. If the same force is not applied, a twisting force will be applied to the contact, and the contact will be damaged. there were.

Further, in the conventional connector, a large number of contacts are required for the connector as the functions of the electronic equipment become more sophisticated. However, as the number of contacts increases, the insertion / removal operation requires a greater force. become. For this reason, in the conventional connector, in order to improve the operability of the removal lever, in the conventional operation lever, the ratio of the leverage boost is increased or the operating area of the force point of the operation unit 4 (the force applied by the finger) is increased. It is necessary to increase the area of the part where
There is a limit to this from the point of storage, and operability at the time of removal cannot be improved from this point either.

An object of the present invention is to provide a connector which can improve the operability at the time of insertion and removal of a plug connector and can prevent the contact from being damaged at the time of insertion and removal.
