[Problems to be solved by the invention]
In recent years, in this type of connector, with the miniaturization of electric equipment (electronic equipment), the demand for further miniaturization has become stronger, and the demand for narrower pitch has become stronger. It has become necessary to provide contact portions on both sides.
However, the connector having the above-described structure cannot cope with the FPC having the contact portions on both sides and cannot cope with the narrow pitch.
That is, in the case of the ZIF type as described in Document 1, after the FPC is inserted into the housing, the FPC is pressed against one side by the slider to make contact with the contact, and the FPC has contact portions on both front and back surfaces. Cannot be used (it can only be pressed against one side). Also, in a so-called piano touch type in which the slider is rotated on the FPC insertion side of the housing as in Document 2, similarly to the ZIF type, the FPC is pressed to one side by the slider to contact the contact. It cannot be used for FPC with contact portions on both front and back sides (it can only be pressed against one side).
[0007]
The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a connector which can cope with a narrow pitch and which can cope with an FPC having contact portions on both sides.
[0008]
[Means for Solving the Problems]
An object of the present invention is to provide a connector which is detachably fitted to an FPC, and has a required number of contacts having a contact portion which comes into contact with the FPC, and a fitting opening in which the contact is held and fixed and the FPC is inserted. A connector having a housing having a contact portion on the front and back sides of the FPC, two types of contacts are used, and one contact is inserted from the opposite side of the fitting opening of the housing, and the contact portion of the contact is formed by the FPC.
