Claim 4

A plug-type connector according to claim 1 , wherein the holder includes, on the placing plate, a pair of holding frames for defining grooves into which a pair of lateral edges of the end portion of the FFC can be introduced, respectively, the fixing member includes a pair of projection portions which project from the annular portion to come in contact with the corresponding holding frames of the holder, the engagement portions being formed on the projection portions, and the corresponding holding frames and the projection portions are combined with each other, thus forming a part of an insertion projecting portion to be inserted into an insertion concave of a mating connector.

Claim 5

A plug-type connector for connecting an FFC, comprising: a holder including a placing plate on which an end portion of the FFC is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and engagement portions which are engageable with corresponding engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, wherein a reinforcing sheet is attached to a backside of the end portion of the FFC for holding exposed conductors in a row, and a pulling-out preventing projection is formed on the placing face of the placing plate of the holder, the pulling-out preventing projection being engageable with an edge portion of the reinforcing sheet of the FFC.

Claim 6

A plug-type connector for connecting an FFC, comprising: a holder including a placing plate on which an end portion of the FFC is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and engagement portions which are engageable with corresponding engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, wherein a reinforcing sheet is attached to a backside of the end portion of the FFC for holding exposed conductors in a row, and a pulling-out preventing projection is formed on the placing face of the placing plate of the holder, the pulling-out preventing projection being engageable with an edge portion of the reinforcing sheet of the FFC.

Claim 7

A plug-type connector for connecting an FFC, comprising: a holder including a placing plate on which an end portion of the FFC is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and engagement portions which are engageable with corresponding engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, wherein a wrong-side insertion preventing portion is formed on a backside of the placing face of the placing plate for preventing the fixing member from being inversely assembled with the placing plate.

Claim 8

A plug-type connector for connecting an FFC, comprising: a holder including a placing plate on which an end portion of the FFC is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and engagement portions which are engageable with corresponding engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, wherein a wrong-side insertion preventing portion is formed on a backside of the placing face of the placing plate for preventing the fixing member from being inversely assembled with the placing plate.

Claim 9

An electric connector provided with a plug-type connector and a receptacle-type connector combined with the plug-type connector, the plug-type connector having an insertion projecting portion to be inserted into an insertion concave of the receptacle-type connector, the receptacle-type connector including: a housing defining the insertion concave into which the insertion projecting portion of the plug-type connector is inserted; and a plurality of contacts arranged side by side in the insertion concave, the plug-type connector further including: a holder including a placing plate on which an end portion of a FFC having a laterally-extending cable width is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and a pair of engagement portions which are engageable with corresponding ones of a pair of engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, engaged ones of the engagement portions and the corresponding engaged portions being disposed opposite one another laterally outside of the cable width.

Claim 10

An electric connector provided with a plug-type connector and a receptacle-type connector combined with the plug-type connector, the plug-type connector having an insertion projecting portion to be inserted into an insertion concave of the receptacle-type connector, the receptacle-type connector including: a housing defining the insertion concave into which the insertion projecting portion of the plug-type connector is inserted; and a plurality of contacts arranged side by side in the insertion concave, the plug-type connector further including: a holder including a placing plate on which an end portion of a FFC having a laterally-extending cable width is placed as temporarily held; and a fixing member capable of fixing the end portion of the FFC to the holder, the fixing member including: an annular portion into which the placing plate of the holder with the end portion of the FFC placed thereon, is inserted together with the FFC; and a pair of engagement portions which are engageable with corresponding ones of a pair of engaged portions of the holder when the annular portion is brought toward the holder with the FFC previously inserted into the annular portion, engaged ones of the engagement portions and the corresponding engaged portions being disposed opposite one another laterally outside of the cable width.

Claim 11

An electric connector according to claim 6 , wherein the holder includes, on the placing plate, a pair of holding frames for defining grooves into which a pair of lateral edges of the end portion of the FFC can be introduced, respectively, the fixing member includes a pair of projection portions which project from the annular portion to come in contact with the corresponding holding frames of the holder, the engagement portions being formed on the projection portions, and the corresponding holding frames and the projection portions are combined with each other, thus forming a part of the insertion projecting portion.
