The present invention relates to a connector to which an FPC (Flexible Printed Circuit) is connected.

In recent years, miniaturization of products has been accelerated in the fields of electronic devices such as mobile phones and digital cameras. Electronic components and printed circuit boards are mounted in such electronic devices. In order to connect these electronic components and a printed board, planar flexible FPC (flexible printed circuit) and the connector for this FPC are used a lot. For this reason, the FPC connector is required to be miniaturized including a reduction in mounting height (lower magnification).

In order to solve this problem, there is disclosed a connector for FPC which can secure the conduction to the FPC by preventing the opening and bending of the cover while achieving low magnification (see, for example, Japanese Patent Laid-Open No. 2002-42939). ).

This disclosed connector specifically includes an insulative housing having an opening that is open upward, a fork-type contact provided in the housing and extending toward the opening, and an insulative cover provided in the housing to open and close the opening. A member is provided.

In this connector, when the lid member is rotated, the pressing portion provided at the end edge of the lid member rotates while pressing the FPC toward the elastic member portion side of the fork-type contact. When the lid member is completely closed, the pressing portion is clamped together with the FPC by the fixing member portion and elastic member portion of the fork-type contact. At this time, the pressing portion contacts the engaging recess of the fixing member portion, but in order to engage the stopper of the fixing member portion, rotation of the pressing portion can be prevented to prevent opening or bending of the lid member.

By the way, a pair of guide walls are erected at both edges of the housing lower plate part. These pairs of guide walls fit into grooves formed in the side edges of the lid member to restrict the movement of the lid member.

Thus, in the conventional FPC connector, since the guide wall is provided in the lower plate part, there existed a problem that the structural member of a connector became large and a cost became high.

An object of the present invention is to provide a connector having a simple configuration for easily solving the above-described problems, which can easily position an FPC, and a portable telephone using the same.
