Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector capable of temporarily holding a connection object when inserting it, and surely preventing the connection object from being pulled out after it is connected. <P>SOLUTION: If a flexible circuit 1 is inserted in a connector body 10 with a turnable member 30 turned to a prescribed upper turning movement position, the engagement part 41a of a temporarily holding member 40 is engaged with the cut part 1b of the flexible circuit 1, and if the turnable member 30 is turned to a prescribed lower turning movement position, the turnable member 30 abuts on the engagement part 41a of the temporarily holding member 40 to regulate the movement of the engagement part 41a in the engagement releasing direction. Thereby, the flexible circuit 1 can be temporarily held when it is inserted, and after the turnable member 30 is turned to the lower turning movement position, if force in the pulling direction is applied to the flexible circuit 1, the engagement of the temporarily holding member 40 with the flexible circuit 1 is not released, and the flexible circuit 1 can be therefore surely prevented from being pulled out in the anti-insertion direction. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a connector for connecting, for example, a flexible printed circuit (FPC) or a flexible flat cable (FFC).

  Conventionally, as this type of connector, a connector body that can insert a connection object made of FPC or FFC into a predetermined position, a plurality of terminals that are in electrical contact with the connection object inserted into the connector body, and a connector body And a pivot member provided so as to be pivotable. After inserting the connection object into the connector body with the pivot member pivoted to a predetermined position, the pivot member is pivoted to another predetermined position. By this, what connected the connection target object to each terminal with the rotation member is known (for example, refer patent document 1).

However, in the connector, since the connection target is not held until the connection target is pressed against each terminal by the rotating member after the connection target is inserted into the connector body, the connection target does not come off. In addition, there is a problem that the rotating member must be operated while being held down by hand, resulting in poor workability. Therefore, when a temporary holding member having engagement portions that can be engaged with the notches provided on both sides in the width direction of the connection object is provided and the connection object is inserted into the connector body, the temporary holding member is engaged due to elastic deformation. It is known that the joint part passes over between the tip of the connection object and the notch and engages with the notch part, and the temporary holding member restricts the movement of the connection object in the anti-insertion direction. (For example, refer to Patent Document 2).

  By the way, in the connector, even after the connection object is inserted into the connector body, the connection object is only held by the elastic force of each terminal even when the connection object is pressed against each terminal by the rotating member. Therefore, when a force in the anti-insertion direction is applied to the connection target, the connection target may come out of the connector body or may be displaced. In this case, the engagement portion of the temporary holding member is engaged with the notch portion of the connection object, but this engagement state is held only by the elastic force of the temporary holding member. Pulling in the anti-insertion direction could not be reliably prevented.

In the connector in which the engaging portion gets over the gap between the tip of the connection object and the notch portion by the elastic deformation of the temporary holding member and is engaged with the notch portion. When the is pivoted to another predetermined position, the pivoting member abuts against the engaging portion of the temporary holding member to restrict the movement of the engaging portion in the disengagement direction.

  As a result, when the connection object is inserted into the connector main body with the rotation member rotated to a predetermined position, the engaging portion of the temporary holding member is engaged with the notch portion of the connection object, and the rotation member is moved to the other position. When the rotation member is rotated to the predetermined position, the rotation member comes into contact with the engagement portion of the temporary holding member, and the movement of the engagement portion in the disengagement direction is restricted. In addition, after the rotation member is rotated to another predetermined position, the engagement between the temporary holding member and the connection object is released even if a force in the pulling direction is applied to the connection object. There is no.

  According to the present invention, the connection object can be temporarily held at the time of insertion, and even if a force in the pulling direction is applied to the connection object after connection, the engagement between the temporary holding member and the connection object is released. Therefore, it is possible to reliably prevent the connection object from being pulled out in the anti-insertion direction.
