When the insertion port 21 of the connector 10 is viewed from the front, a pair of holding fittings 1 are disposed to face each other in the left-right direction of the outer casing 2. The holding fitting 1 is arranged such that the insertion opening 21 is viewed from the front, and its outer shape is U-shaped, and the position correcting portion 1b is accommodated inside the U-shape. The holding fitting 1 is arranged such that the insertion opening 21 is viewed from the front, and the upper surface of the first piece 1f of one of the U-shapes forms a plane substantially parallel to the covering portion 2a of the outer casing 2. Further, the holding fitting 1 is disposed such that the insertion opening 21 is viewed from the front, and the lower surface of the other U-shaped second piece 1g is substantially flush with the outer bottom surface of the outer casing 2 (the lower surface of the base wall portion 2b).

Further, the guide portion 1a includes a height position correcting portion 1a2 that is not engaged with the terminal portion 34 of the joint 3 to guide the insertion of the FPC 100 into the insertion port 21. The mounting portion 1a1 is thinner than the thickness of the base wall portion 2b or the terminal portion 34. Since the mounting portion 1a1 is made of a metal material, the mounting portion 1a1 can maintain strength even if it is thinner than the base wall portion 2b. The placing portion 1a1 is disposed closer to the outer bottom surface side of the outer casing 2 than the height position correcting portion 1a2. The height position correcting unit 1a2 is erected from the mounting portion 1a1, and its height is substantially higher than the height of the terminal portion 34 electrically connected to the protruding portion 32a which is a contact portion of the tip end of the plurality of terminals 3 on the insertion port 21 side. equal.

The inclination angle is substantially the same as the inclination angle with respect to the insertion/removal direction of the front end edge portion 34a of the terminal portion 34, but may be different. In either case, the connector 10 can easily insert the FPC 100 into the insertion port 21 as compared with the case where the guide portion 1a is not provided. Moreover, when the front end edge portion 34a of the terminal portion 34 is not provided, the guide portion 1a appropriately sets the inclination angle of the height position correction portion 1a2 with respect to the insertion/removal direction of the FPC 100 so that the height of the height position correction portion 1a2 is made. The height of the top surface 34b of the terminal portion 34 may be equal to or higher than the height. In other words, when the distal end of the terminal portion 34 is at a right angle with respect to the insertion/removal direction, the guide portion 1a may set the height of the height position correction portion 1a2 to a height equal to or greater than the top surface 34b of the terminal portion 34.

The guide portion 1a can prevent the front end portion of the FPC 100 from being caught by the terminal portion 34 protruding from the outer casing 2 by protruding toward the front of the insertion opening 21. Further, the first piece 1f holding the U-shape of the fitting 1 is provided with the opening cut portion 1e so that the tip end of the FPC 100 is easily placed on the placing portion 1a1.

Further, the holding fitting 1 is provided with the cut portions 1aa and 1da as appropriate so that the bending process of the plate-like body can be easily performed. The holding member 1 may be provided with not only the cut portions 1aa and 1da but also a thin plate.

Further, in the case where the connector 10 constitutes the outer casing 2 using a synthetic resin molded article, it is necessary to increase the strength of the outer casing 2 as the connector 10 is miniaturized. The connector 10 of the present embodiment is passed through the insertion opening 21 of the outer casing 2. The end portions on both sides are provided with the holding fitting 1 for temporarily holding the FPC 100, and the strength of the outer casing 2 can be improved.

When the FPC 100 is inserted, the holding fitting 1 can easily insert the FPC 100 into the insertion port 21 by the position correcting portion 1b. Further, in the connector 10 of the present embodiment, the guide portion 1a of the holding metal fitting 1 provided at both end portions of the insertion opening 21 of the outer casing 2 protrudes forward from the outer casing 2. Therefore, the connector 10 can guide the insertion of the FPC 100 from the mounting portion 1a1 along the height position correcting portion 1a2 by pushing the FPC 100 placed on the mounting portion 1a1 of the guiding portion 1a toward the insertion port 21. That is, when the connector 10 is inserted into the outer casing 2, even if the operator does not correctly ascertain the position of the insertion opening 21, the engagement of the joint 3 can be suppressed and easily inserted into the outer casing 2.

In the connector 10 of the present embodiment, the position of the FPC 100 in the height direction is corrected by the guide portion 1a of the holding fitting 1, and the FPC 100 can be inserted by avoiding the terminal portion 34 protruding from the outer casing 2 to the front. Thereby, the connector 10 of the present embodiment is in the step of inserting the FPC 100 into the connector 10, and the positional deviation can be corrected by the guide portion 1a integrally formed with the holding metal fitting 1 to facilitate insertion.

Therefore, even when the height of the insertion opening 21 of the FPC 100 is reduced as the connector 10 is miniaturized, the connector 10 can suppress the front end of the FPC 100 from being caught by the terminal portion 34 and reduce the insertion property. .

In addition, as shown in FIG. 4, the guide portion 1a of the present embodiment is provided with a pair of guide portions 1a and 1a which are respectively protruded from the front side of the insertion opening 21 in the width direction. In other words, the pair of guiding portions 1a and 1a can only mount both end portions in the width direction with respect to the FPC 100. As a result, the FPC 100 can be guided into the insertion port 21 with a small component configuration.

Hereinafter, the operation when the FPC 100 is inserted or removed by the connector 10 of the present embodiment will be described.

As shown in FIGS. 1, 2, and 3, the connector 10 is placed at a substantially upright position (a position substantially orthogonal to the support portions 31, 41 of the joints 3, 4) before the FPC 100 is connected. In this state, the connector 10 is a cam portion 51 that does not press the recess 36 of the joint 3. Therefore, the joint 3 is not elastically deformed by the spring portion 32 and the connecting portion 33, and the distance between the protruding portion 32a of the spring portion 32 and the protruding portion 31a of the supporting portion 31 is a predetermined interval at which the FPC 100 can be inserted and removed. Similarly, in this state, the connector 10 is a cam portion 52 that does not press the recess 46 of the joint 4. Therefore, the joint 4 is not elastically deformed by the spring portion 42 and the connecting portion 43, and the distance between the protruding portion 42a of the spring portion 42 and the protruding portion 41a of the supporting portion 41 is a predetermined interval at which the FPC 100 can be inserted and removed. That is, the connector 10 is in a state where the lever 5 is in the non-stopping position, and between the protruding portion 31a of the connector 3 and the protruding portion 32a, and between the protruding portion 41a and the protruding portion 42a of the connector 4. The distances are each a larger separation distance than the thickness of the FPC 100.

Thus, the connector 10 enables the insertion resistance of the FPC 100 to be inserted into the connector 10 to be small, so that the flexible FPC 100 can be easily inserted into the connector 10. Further, the connector 10 may be in a state where the lever 5 is rotated to the non-stop position, and the protruding portions 31a and 32a of the joint 3 or the protruding portions 41a and 42a of the joint 4 are in contact with the FPC 100. The connector 10 can be in contact with the FPC 100 as the protruding portion 32a of the joint portion of the joint 3 or the protruding portion 42a of the joint portion of the joint 4 even when the rod 5 is rotated to the non-stopping position. In a manner, the FPC 100 is inserted and an electrical connection is established at the same time. Further, since the connector 10 is in a state in which the holding force of the FPC 100 is relatively small as compared with the case where the lever 10 is in the stop position, the FPC 100 relatively becomes in a state of being easily detached.

The connector 10 guides the FPC 100 along the guide groove 24 provided in the partition wall 23 when the FPC 100 is inserted into the casing 2 from the insertion port 21 while the rod 5 is placed in the non-stop position.

The connector 10 is provided with a guiding portion 1a which is a guiding portion 1a of the holding fitting 1 which protrudes in front of the insertion opening 21 of the outer casing 2 for loading the FPC 100 and not engaging the connector 3 It is tight and can be inserted into the insertion port 21. The connector 10 can mount the front end portion of the FPC 100 on the placing portion 1a1 that protrudes from the insertion opening 21 of the outer casing 2. When the connector 10 is inserted into the insertion port 21, the connector 10 is inserted into the height position correcting portion 1a2 that is continuous with the placing portion 1a1. Thereby, the connector 10 can guide the front end portion of the FPC 100 to the insertion port 21 along the guiding portion 1a.

The FPC 100 inserted into the inside of the connector 10 from the insertion port 21 is inserted between the support portions 31, 41 of the joints 3, 4 and the spring portions 32, 42. When the FPC 100 is further inserted into the inside of the casing 2, the front end portion of the FPC 100 abuts against the positioning surface 23a of the joint 3. Thereby, the connector 10 can position the front end portion of the FPC 100 with respect to the joints 3, 4.

The connector 10 is configured such that when the lever 5 is rotated into a position substantially parallel to the support portions 31, 41 of the joints 3, 4 in a state where the FPC 100 is inserted into the inside of the outer casing 2, the cam portion 51 of the lever 5 pushes the joint 3 Concave 36. In the joint 3, the spring portion 32 and the connecting portion 33 are elastically deformed with the connecting portion 33 as a fulcrum, and the protruding portion 32a of the spring portion 32 is displaced to the side of the supporting portion 31. Thereby, the protruding portion 32a of the connector portion 10 of the spring portion 32 comes into contact with the conductor pattern 101 provided in the FPC 100 with an elastic force. Similarly, the cam portion 52 of the connector 10 tie rod 5 pushes the recess 46 of the joint 4. The joint 4 elastically deforms the spring portion 42 and the connecting portion 43 with the connecting portion 43 as a fulcrum, and the protruding portion 42a of the spring portion 42 is displaced to the side of the supporting portion 41. Thereby, the protruding portion 42a of the connector 10 of the spring portion 42 comes into contact with the conductor pattern 101 provided in the FPC 100 with an elastic force.

The connector 10 is pushed by the protruding portions 31a and 32a of the spring portion 32 and the protruding portions 41a and 42a of the spring portion 42 in a state where the lever 5 is rotated to the stop position. At FPC100. The connector 10 holds the FPC 100 between the protruding portion 32a of the spring portion 32 and the protruding portion 31a of the support portion 31. Further, the connector 10 holds the FPC 100 between the protruding portion 42a of the spring portion 42 and the protruding portion 41a of the support portion 41. The connector 10 is in a state in which the conductor patterns 101 of the joints 3, 4 and the FPC 100 are electrically connected by the contact pressure of the joints 3, 4.

On the other hand, the connector 10 is in a state where the FPC 100 is connected to the connector 10, and when the lever 5 is rotated from the retaining position to the non-stopping position, the cam portions 51, 52 push the recesses 36, 46 of the joints 3, 4. The strength is weak. The joints 3 and 4 are displaced from the FPC 100 by the elastic restoring forces of the spring portions 32 and 42 and the connecting portions 33 and 43 to displace the protruding portions 32a and 42a of the spring portions 32 and 42. The connector 10 is weakened by the force of the joints 3, 4 holding the FPC 100, so that the FPC 100 may be easily detached.

When the connector 10 of the present embodiment inserts the FPC 100 from the insertion port 21, the front end portion of the FPC 100 abuts on the positioning surface 23a provided on the outer casing 2. The connector 10 temporarily holds the FPC 100 by fitting the temporary holding portion 1c of the holding metal fitting 1 to the temporary holding concave portion 103 provided at both ends in the width direction of the front end portion side of the FPC 100. Thereby, the connector 10 prevents the FPC 100 from coming off the insertion port 21 before the inserted FPC 100 is stopped by the lever 5. Also, the connector 10 can properly position the relative position of the FPC 100 relative to the joints 3, 4. That is, the connector 10 can reduce the deviation of the contact position where the protruding portions 32a, 42a of the contact portions of the spring portions 32, 42 come into contact with the FPC 100. The connector 10 can improve the reliability of the electrical connection by electrically contacting the connectors 3, 4 with the FPC 100 at a specified position.

Further, as shown in FIG. 4, the FPC 100 connected to the casing 10 of the present embodiment is provided with the wide portion 102 of the conductor pattern 101 in contact with the joint 3 with respect to the wide portion 102 of the conductor pattern 101 in contact with the joint 4. In FPC100 The front end side of the FPC100 is inserted and removed. Further, the FPC 100 sets the length of the wide portion 102 of the conductor pattern 101 in contact with the joint 4 to be longer than the length dimension of the wide portion 102 in contact with the joint 3 in the insertion and removal direction of the FPC 100.
