At this time, the distance between the first protrusions 58 of the arms 54 and 56 is such that the insertion portion 76 of the FPC 70 is passed through, and therefore the distance T1 of the insertion portion 76 is open. . However, since the thickness T2 of the step portion 82 of the FPC 70 is thicker than the thickness T1 of the insertion portion 76, the first projecting portion 58 of each arm portion 54, 56 contacts the step portion 82 of each arm portion 54, 56. Will come to be. Note that the distal end portion 80 of the insertion portion 76 of the FPC 70 is in a position where it does not come into contact with the second protrusions 60 of the arm portions 54 and 56.

  When the FPC 70 is further inserted from this state, as shown in FIG. 8B, the step portion 82 of the FPC 70 presses the first protrusion 58 of each arm portion 54, 56, and each arm portion 54, 56 becomes the contact main body 46. As a result, the step portion 82 is inserted into the first protrusion 58 of each of the arm portions 54 and 56. At this time, the first protrusions 58 of the arm portions 54 and 56 are in a state where the distance of the thickness T2 of the step portion 82 of the FPC 70 is open.

  At this time, the first projecting portions 58 of the arm portions 54 and 56 of the contact 44 are opened, and the gap between the second projecting portions 60 is also larger than the gap C2 before opening. In the first embodiment, when the first protrusion 58 of each of the arms 54 and 56 is in a state where the distance T2 of the step 82 of the FPC 70 is open, for example, the second protrusion 60 is inserted into the FPC 70. A gap is formed so that the portion 76 can pass through.

  Thereafter, when the FPC 70 is further inserted, as shown in FIG. 9A, the insertion portion 76 of the FPC 70 is moved to the arm portion 54 while the first protrusion 58 of each arm portion 54, 56 passes through the step portion 82 of the FPC 70. , 56 are inserted into the gaps of the second protrusions 60. At this time, the second projecting portions 60 of the arm portions 54 and 56 of the contact 44 are wider than the gap C2 before opening because the first projecting portion 58 is pressed by the step portion 82 of the FPC 70. Since the gap that allows the insertion portion 76 of the FPC 70 to pass therethrough is opened, the insertion portion 76 of the FPC 70 is smoothly inserted into the second protrusions 60 of the arm portions 54 and 56. .

  That is, since the second protrusions 60 of the arms 54 and 56 are formed at positions close to the contact body 46, when only the second protrusion 60 is pressed to open the arms 54 and 56, A large force is required and it becomes difficult to insert the FPC 70. However, when the first protrusions 58 formed on the distal end side far from the contact body 46 are pressed to open the arms 54 and 56, the force is small. Since it can be opened, the FPC 70 can be smoothly inserted into the second protrusion 60.

  Further, when the FPC 70 is inserted, as shown in FIG. 9B, the step portion 82 of the FPC 70 that has pressed the first projection 58 of each arm portion 54, 56 passes through the first projection 58, and the first projection 58 It comes to be disposed between the protrusion 58 and the second protrusion 60. The first protrusions 58 of the arm portions 54 and 56 are not pressed from the step portion 82 of the FPC 70, so that the arm portions 54 and 56 are moved toward the direction narrowed by the elastic force, that is, the FPC 70 side. . Therefore, the second protrusions 60 of the arm portions 54 and 56 are brought into contact with the contact portions 78 of the insertion portion 76 of the FPC 70, and the FPC 70 is sandwiched.

  At this time, the FPC 70 is sandwiched between the second protrusions 60 formed on the contact main body 46 side of the respective arm portions 54 and 56 of the contact 44, whereby the first protrusions 58 formed on the distal end side of the contact 44. Compared with the case of being sandwiched between the two, it is possible to obtain a large contact pressure and to prevent the FPC from being easily pulled out.

  On the other hand, the first protrusions 58 of the arms 54 and 56 are arranged on the side of the band-shaped portion 84 of the FPC 70. At this time, the gaps C1 and C2 between the first protrusions 58 and the second protrusions 60 of the arms 54 and 56 are formed substantially the same, so that the second protrusions 60 of the arms 54 and 56 are formed. In the state where the insertion portion 76 is sandwiched, that is, when the gap between the second protrusions 60 of the arm portions 54 and 56 is T1, the arm portions 54 and 56 disposed on the side of the belt-shaped portion 84 of the FPC 70. The gap between the first projections 58 is wider than the thickness T3 of the strip 84, and the strip 84 and the first projections 58 of the arm portions 54 and 56 are not in contact with each other and have a gap. It has become. Therefore, the insertion portion 76 of the FPC 70 is held only by the second protrusion 60 of the contact 44.

  Further, the first protrusions 58 of the arm portions 54 and 56 are arranged so as to cover the belt-like portion 84 side of the step portion 82 of the FPC 70. That is, in the state where the insertion portion 76 of the FPC 70 is sandwiched between the second protrusions 60 of the arm portions 54 and 56, the gap between the first protrusions 58 of the arm portions 54 and 56 is larger than the thickness T2 of the step portion 82. This is because it becomes narrower. As described above, the first protrusions 58 of the arm portions 54 and 56 cover the belt-like portion 84 side of the stepped portion 82, so that the FPC 70 is prevented from being pulled out, and the first protrusion 58 is less likely to come off. can do.

  Note that the length in the insertion direction from the distal end portion 80 of the insertion portion 76 of the FPC 70 to the end of the step portion 82 is L1, the length of the step portion 82 is L2, and the arm portions 54 and 56 of the contact 44 are The distance between the first protrusion 58 and the second protrusion 60 is S1, the distance from the first protrusion 58 to the inner side of the housing 14 in the internal space 36 of the housing 14, and the distance to the partition 42 in the first embodiment. When the distance is S2, the length (L1 + L2) of the length L1 of the insertion portion 76 of the FPC 70 and the length L2 of the stepped portion 82 is the first length of each arm portion 54, 56 of the contact 44 of the connector member 12. The length L2 of the step portion 82 of the FPC 70 is formed so as to be shorter than the distance S2 between the protruding portion 58 and the partition portion 42 on the back side of the housing 14, and each arm portion 54 of the contact 44, 56 first protrusions 58; 2 is formed to be shorter than the distance S1 of between projections 60. With such a configuration, the FPC is sandwiched and fitted into the contact in the connector member. Thus, the fitting of the FPC to the connector member is completed.

  In addition, although the case where FPC as a to-be-connected member was connected to the connector member was demonstrated in the connector of Embodiment 1, not only this but a to-be-connected member can also be made into FFC.
