  • the second flexible cable 57 is arranged along the surface of the second housing 46 opposite to the second boss pin 54 . According to this configuration, it is not necessary to form a hole through which the first boss pin 37 penetrates in the first flexible cable 40 . There is no need to form a hole through which the second boss pin 54 penetrates in the second flexible cable 57 . As a result, a reduction in strength of the first flexible cable 40 and the second flexible cable 57 due to the formation of the holes can be avoided.
  • the first flexible cable 40 has a first connection end 41 for connecting with the first terminal fitting 39 attached to the first housing 27 .
  • the second flexible cable 57 has a second connecting end 58 for connecting with a second terminal fitting 56 attached to the second housing 46 .
  • a second boss pin 54 penetrates through the first connecting end portion 41
  • a first boss pin 37 penetrates through the second connecting end portion 58 .
  • At least a portion of the first connection end portion 41 and at least a portion of the second connection end portion 58 are arranged in different regions in the width direction orthogonal to the stacking direction of the first housing 27 and the second housing 46. ing. With this configuration, it is possible to provide a margin in the pitch between the first boss pin 37 and the second boss pin 54 in the width direction.
  • the flexible cable connector has an outer housing 10 that accommodates the first housing 27 and the second housing 46 in a stacked state.
  • a lock arm 12 is formed in the center of the outer housing 10 in the width direction.
  • a notch 33 is formed in the first housing 27 to avoid interference with the lock arm 12 .
  • the pair of first connection end portions 41 are arranged so as to sandwich the lock arm 12 in the width direction. According to this configuration, it is possible to prevent the load from being concentrated on some of the first boss pins 37 when a tensile force acts on the first flexible cable 40 .
  • a second window hole 20 exposing the first boss pin 37 and a first window hole 15 exposing the second boss pin 54 are formed in the outer surface of the outer housing 10 . If the inner module 25 is properly inserted into the outer housing 10 , the first boss pin 37 can be seen through the second window hole 20 and the second boss pin 54 can be seen through the first window hole 15 . That is, the positional relationship between the first housing 27 and the second housing 46 with respect to the outer housing 10 can be confirmed visually.
  • the outer housing 10 is formed with a first holding portion 13 and a second holding portion 18 capable of swinging in the stacking direction of the first housing 27 and the second housing 46 .
  • the first holding portion 13 and the second holding portion 18 hold the first flexible cable 40 and the second flexible cable 57 in a state of sandwiching them in the stacking direction by being held in the closed position.
  • a first window hole 15 and a second window hole 20 are formed in the first holding portion 13 and the second holding portion 18 .
  • the second boss pin 54 is fitted in the first window hole 15 and the second boss pin 54 is fitted in the second window hole 20 . 1 boss pin 37 is fitted.
  • the first holding portion 13 is moved to the closed position while the first holding portion 13 is swinging to the closed position. It interferes with the second boss pin 54 and interferes with the first boss pin 37 while the second holding portion 18 is swinging to the closed position. Whether or not the first housing 27 and the second housing 46 are accommodated in the outer housing 10 in an appropriate state can be determined based on the presence or absence of such interference.
  • the first housing 27 has a first front locking portion 32 and a first rear locking portion 36 as locking portions for holding the first housing 27 and the second housing 46 in a stacked state.
  • the second housing 46 has a second front locking portion 51 and a second rear locking portion 53 as locking portions for holding the first housing 27 and the second housing 46 in a stacked state. According to this configuration, the locking action between the first front locking part 32 and the second front locking part 51 and the locking action between the first rear locking part 36 and the second rear locking part 53 Therefore, the first housing 27 and the second housing 46 can be integrated before being assembled to the outer housing 10 . Thereby, the workability when attaching the inner module 25 to the outer housing 10 is good.
  • the invention is not limited to the embodiments illustrated by the above description and drawings, but is indicated by the claims.
  • the present invention includes all modifications within the meaning and equivalents of the claims and the scope of the claims, and also includes the following embodiments.
  • the first flexible cable is arranged on the surface of the first housing opposite to the first boss pin, but the first flexible cable may be arranged on the same surface as the first boss pin.
  • the second flexible cable is arranged on the surface of the second housing opposite to the second boss pin, but the second flexible cable may be arranged on the same surface as the second boss pin.
  • Example 1 only a portion of the first connection end and a portion of the second connection end are arranged in different regions in the width direction.
  • connection ends may be arranged in different regions in the width direction, or the entirety of the first connection end and the entirety of the second connection end may be arranged in the same position in the width direction. good.
  • first flexible cable is formed with a pair of first connecting end portions in the first embodiment, the number of the first connecting end portions may be only one.
  • the first connecting end portion is arranged so as to sandwich the lock arm, but at least a part of the first connecting end portion may be arranged so as to overlap the lock arm.
  • the window holes are formed in the outer housing in the first embodiment, the outer housing may have no window holes.
  • the first boss pin and the second boss pin are fitted into the window hole with the holding portion sandwiching the first housing and the second housing, but the holding portion sandwiches the first housing and the second housing. Also, the first boss pin and the second boss pin may not be fitted into the window holes.
  • Example 1 above only two modules, the first module and the second module, are used, but three or more modules may be stacked.
