  • the hook 311 of the locking member 30 and the contact portion 432 of the protruding piece 43 of the shell 40 are located on the same imaginary plane VP.
  • This imaginary plane VP is a plane that extends in a direction substantially perpendicular to the center of rotation RC of the rotational movement of the locking member 30 relative to the housing 10.
  • the portion 313 (see FIG. 6) of the locking member 30 with which the contact portion 432 is in contact can be positioned near the hook 311.
  • the protruding piece 44 is disposed at a position on the upper plate portion 41 of the shell 40 that corresponds to the connecting portion 32 of the locking member 30. In other words, this protruding piece 44 is disposed closer to the center of the upper plate portion 41 in the width direction of the shell 40 (X direction in the figure) than the protruding piece 43. As shown in Figure 7 and the above-mentioned Figure 4, this protruding piece 44 has a fixed end 441, a contact portion 442, and an extension portion 443.
  • the protruding piece 44 is connected to the edge of the opening 412 of the upper plate portion 41 at the fixed end 441.
  • the protruding piece 44 extends from the fixed end 441 toward the rear of the connector 1 (the +Y direction in the figure).
  • the protruding piece 44 has a contact portion 442 at its tip that protrudes downward (the -Z direction in the figure).
  • the contact portion 442 contacts the upper surface (the surface on the +Z direction side in the figure) of the connecting portion 32 of the lock arm 31.
  • the portion of the connecting portion 32 with which the contact portion 442 contacts is a portion forward of the center of rotation RC in the front-rear direction of the connector 1 (the Y direction in the figure) (the -Y direction in the figure).
  • An extension portion 443 extends between the fixed end 441 and the contact portion 442, and the fixed end 441 and the contact portion 442 are connected by the extension portion 443. That is, the protruding piece 44 is a spring piece with a cantilever support structure that is elastically deformable with the contact portion 442 as the free end, and presses the locking member 30 downward (in the -Z direction in the figure), urging the locking member 30 toward the above-mentioned locked position.
  • Figures 10(a) to 10(c) are cross-sectional views showing the operation of connector 1 in an embodiment of the present invention. Specifically, Figure 10(a) is a diagram showing the state in which flexible printed wiring board 60 is being inserted into connector 1, Figure 10(b) is a diagram showing the state in which locking member 30 has locked flexible printed wiring board 60, and Figure 10(c) is a diagram showing the state in which flexible printed wiring board 60 is being removed from connector 1 after unlocking locking member 30. Note that Figures 10(a) to 10(c) are cross-sectional views corresponding to Figure 6 described above.
  • the worker When inserting the flexible printed wiring board 60 into the connector 1, as shown in FIG. 10(a), the worker first inserts the flexible printed wiring board 60 into the insertion portion 11 of the housing 10 of the connector 1 and abuts the tip of the flexible printed wiring board 60 against the hook 311 of the locking member 30.
  • the locking member 30 rotates clockwise in the figure against the biasing force of the protruding pieces 43, 44 of the shell 40, and the hook 311 of the locking member 30 is pushed up and rides onto the protruding portion 64 of the flexible printed wiring board 60.
  • the hook 311 of the locking member 30 and the contact portion 432 of the protruding piece 43 are located on the same imaginary plane VP that extends in a direction substantially perpendicular to the rotation axis RC of the locking member 30. Therefore, the portion 313 of the locking member 30 with which the contact portion 432 is in contact can be positioned close to the hook 311, thereby improving the holding force that holds the flexible printed wiring board 60 of the connector 1.
  • the protruding piece 43 is integrally formed with the shell 40, which also reduces the number of parts in the connector 1.
  • the shell 40 functions as an electromagnetic shield, which further reduces the number of parts in the connector 1.
  • the shell 40 is held in the housing 10 so that the locking member 30 is sandwiched between the housing 10 and the shell 40, so that the locking member 30 is sufficiently prevented from coming loose from the housing 10.
  • the connector 1 in addition to the protruding piece 43, the connector 1 is provided with the protruding piece 44 as a member for biasing the locking member 30, so that the biasing force of the locking member 30 can be reinforced and stabilized.
  • the protruding piece 43 is formed integrally with the shell 40, but if the protruding piece 43 is located on the opposite side of the locking member 30 from the flexible printed wiring board 60, the protruding piece 43 may be a separate member independent of the shell 40 and joined to the shell 40.
  • the protruding piece 44 is formed integrally with the shell 40, but if the protruding piece 44 is located on the opposite side of the locking member 30 from the flexible printed wiring board 60, the protruding piece 44 may be a separate member independent of the shell 40 and joined to the shell 40.
  • the housing 10 is covered with a shell 40 made of a conductive material to provide the connector 1 with an electromagnetic wave shielding function, but instead of the shell 40, the housing 10 may be covered with a cover member made of a non-conductive material such as a resin material.
  • the protruding piece 43 may be formed integrally with the cover member, or the protruding piece 43 may be a separate member independent of the cover member, and the protruding piece 43 may be joined to the cover member.
  • the protruding piece 44 may be formed integrally with the cover member, or the protruding piece 44 may be a separate member independent of the cover member, and the protruding piece 44 may be joined to the cover member.
