The bearing portion 208 only needs to be pivotally mounted so as to be able to rotate with the shaft 185 of the rotating member 18, and the shape and size of the bearing portion 208 moves and rotates when the rotating member 18 rotates. The design is made in consideration of what can be done, workability and strength. In the present embodiment, the bearing portion 208 is provided on the shell 20, but may be provided on the housing 12. Considering wear and the like, it is desirable to provide the shell 20.

  Here, the lock member 22 separated from the shell 20 will be described. Hereinafter, differences from the lock member 202 integrated with the shell 20 will be described.

  Also on the lock member 22, a reinforcing piece 223 similar to the above is integrated with an elastic connecting portion 224 as shown in FIG. 7B. The shape, size and role of the reinforcing piece 223 are the same as described above.

  The shape, size, and arrangement of the engaging portion 225 and the pressing portion 226 provided on the lock member 22 are the same as those described above, and their roles and functions are also the same. The roles and functions of the bent portion of the crank and the elastic connecting portion 224 are the same. Speaking of the difference, it is the connecting part of the elastic connecting part 224.

  Next, the contact 14 will be described. The contact 14 is made of metal and is manufactured by a known press working. The material of the contact 14 is required to be springy or conductive, and can include brass, beryllium copper, phosphor bronze, and the like.

By providing them separately and independently, a partition wall 184 is provided between the adjacent contacts 14 as a result, the locking hole 183 is provided separately and the partition wall 184 is provided. Thus, the strength of the rotating member 18 is prevented from being increased and deformation during rotation is prevented.

  Further, the operation portion 181 is a portion that is pushed by a finger, a jig or the like when the rotation member 18 is rotated. The shape and size of the operation unit 181 may be pressed by a finger or a jig, and is designed as appropriate in consideration of miniaturization, strength, workability, operability, and the like of the connector.

  Furthermore, it is preferable to provide locks 186 that securely lock the rotary member 18 when the rotary member 18 is closed on both sides of the rotary member 18 in the width direction. The shape and size of the lock 186 only needs to be able to be securely locked, and the lock 186 is appropriately designed in consideration of holding force, connector miniaturization, strength, workability and the like.

  Next, the housing 12 will be described. The housing 12 is an electrically insulating plastic and is manufactured by a known technique of injection molding. The material is appropriately selected in consideration of dimensional stability, workability, cost, etc. Generally, polybutylene terephthalate is used. (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The housing 12 is provided with a fitting port 30 into which the FPC 80 is inserted. The fitting port 30 only needs to contain the FPC 80, and is larger than the thickness of the FPC 80. However, when the FPC 80 is inserted, the fitting port 30 has a so-called non-ZIF structure that contacts the contact portion 141 of the contact 14. ing.

  The housing 12 is provided with an insertion hole 121 in which a required number of contacts 14 are mounted, and is fixed by press-fitting, hooking (lance), welding or the like. The insertion hole 121 is provided in a direction from the side on which the rotating member 18 is mounted toward the fitting port 30 side. The contact 14 is inserted from the fitting port 30 side.

  On both sides of the housing 12 in the longitudinal direction, there are provided insertion grooves 122 for receiving the lock members 202 and 22 and mounting holes 123 for receiving the reinforcing pieces 203 and 223. The shape and size of the insertion groove 122 and the mounting hole 123 are in accordance with the shapes of the lock members 202 and 22 and the reinforcing pieces 203 and 223, and considering the holding force, workability, strength, connector miniaturization, and the like. And design accordingly.

  The housing 12 includes a ceiling portion 124 that covers the contact portion 141 of the contact 14. The ceiling portion 124 is a portion that protects the contact portion 141 of the contact 14 from dust and dust. In order to rotate the rotating member 18, the housing 12 is provided with a notch 125 on the side opposite to the insertion direction of the FPC 80.

  The following describes the different contacts. First, a contact for realizing a narrow pitch will be described. The contact also has at least a contact portion and a connection portion. The contact connects a first piece having a contact portion 151 at one end, a second piece having a connection portion 153 connected to the substrate at the other end, the other end of the first piece, and one end of the second piece. What has the connecting portion 155 is referred to as a second contact 15. Furthermore, in this embodiment, an extending portion 154 is provided so as to face the connecting portion 153 as shown in FIG. The extended portion 154 is a portion that plays the same role as described above. In order to reduce the pitch, the contacts 14 and the second contacts 15 are staggered. That is, every other contact 14 is inserted from the direction of the fitting port 30, and the second contact 15 is inserted from the opposite side of the fitting port 30.

  The two contacts 14 and 15 described above may not have the extending portions 144 and 154. In addition, the above-described two contacts 14 and 15 have been described as having an approximately inverted h shape as an example, but in the case of the contact 14, the second contact 14 is extended so as to face the extended portion 144. In the case of the second contact 15, an extension portion may be provided, and a second extension portion extending so as to face the contact portion 151 may be provided, and each may have a substantially inverted H shape. (Not shown)

  The connector may include one of the two contacts 14 and 15 described above, or may include both contacts 14 and 15. A second eye contact portion may be provided at a position facing the contact portion 151 at the tip of the second extending portion of the second contact 15. The two contacts 14 and 15 described above are both subjected to force (insertion force and removal force).

  Next, a contact having a ZIF structure (a force is applied during insertion, but no force is applied during removal) will be described. The contact of the ZIF structure shown in FIG. 4C has the same shape as the second contact 15 described above, and the extended portion 154 of the second contact 15 is a fourth pressing portion 164, and the connecting portion 155 is a fourth contact 16 having an elastic connecting portion 165, and the pressing portion 182 of the rotating member 18 acts on the fourth pressing portion 164 to lift the fourth pressing portion 164, thereby the elastic connecting portion. The fourth contact portion 161 is brought into contact with the contact of the FPC 80 when the fourth contact portion 161 is displaced downwardly, and the fourth contact portion 161 is displaced downward.

  The shape and size of the fourth pressing portion 164 and the elastic coupling portion 165 are appropriately designed so as to satisfy such an action (movement). The fourth contact 16 is applied with force when inserted, but is not applied withdrawn.

  Although not shown, there is a third contact having the same shape as FIG. 4A and a ZIF structure. The third contact also has the extended portion 144 of the contact 14 as a third pressing portion and the connecting portion 144 as an elastic connecting portion. The third pressing portion and the elastic connecting portion are the same as described above. The same applies to the third contact and the fourth contact 16 having a substantially inverted H shape. The connector may include one of the third contact and the fourth contact 16 described above, or may include both the third contact and the fourth contact 16. Further, a second contact portion may be provided on the third contact portion of the third contact and the fourth contact 16 and the opposite side of the fourth contact portion 161. A force is applied to the third contact and the fourth contact 16 during insertion, but force is applied during removal.

  Finally, there is a difference between the rotating member 18 when a force is applied when the FPC 80 is inserted but a force that is not applied when the FPC 80 is removed is a ZIF structure and the lock members 202 and 22 are a Non-ZIF structure. Only the point will be described. As shown in FIG. 8, this can be dealt with by changing the pressing portion 182 of the rotating member 18 by 90 degrees. By changing 90 degrees, when one acts, the other (the one changed 90 degrees) does not act, so that a ZIF structure and a Non-ZIF structure can be realized. That is, when the FPC 80 is inserted (when the rotating member 18 is closed), the pressing portion 182 acts on the pressing portion of each contact 14, 15, 16 and the pressing portion 182 changed by 90 degrees is It does not act on the pressing portions 206 and 226 of the lock members 202 and 22. On the contrary, when the FPC 80 is removed (when the rotating member 18 is opened), the pressing portion 182 does not act on the pressing portions of the respective contacts 14, 15, 16 and the pressing portion changed by 90 degrees. Reference numeral 182 acts on the pressing portions 206 and 226 of the lock members 202 and 22.

  As an application example of the present invention, it is used for a connector 10 used in an electric device or an electronic device such as a mobile phone, a notebook computer, or a digital camera. The present invention relates to a structure that can be securely locked and that can easily unlock the lock member when the connection object is removed.
