  FIG. 6 shows a flexible printed wiring board 40 (hereinafter referred to as an FPC 40) that constitutes a wiring board member inserted into the housing 11 of the connector device 10 through the plate member insertion portion 12.

  The FPC 40 shown in FIG. 6 has a circuit configuration part 41 and a terminal plate part 42 connected thereto. In the terminal plate portion 42, a plurality of contact terminal portions 43 and a plurality of contact terminal portions 44 each drawn from the circuit configuration portion 41 are alternately arranged. The plurality of contact terminal portions 43 are arranged and arranged at a predetermined pitch in a direction along the edge portion 45 of the terminal plate portion 42, and the plurality of contact connection terminals 44 are arranged at the edge portion of the terminal plate portion 42. At a position close to 45, the plurality of contact connection terminals 43 are arranged with a predetermined pitch in the same direction as the arrangement direction of the contact connection terminals 43.

  In addition, the terminal plate portion 42 of the FPC 40 is formed with a pair of engaging portions 46 and 47 that are opposed to each other with the plurality of contact terminal portions 43 and the plurality of contact terminal portions 44 interposed therebetween in the arrangement direction. These engaging portions 46 and 47 each have a notch recess. Further, a guide receiving portion 48 is formed between the edge portion 45 and the engaging portion 46 in the terminal plate portion 42, and also between the edge portion 45 and the engaging portion 47 in the terminal plate portion 42. A guide receiving portion 49 is formed.

  Then, when the FPC 40 is inserted into the housing 11 through the plate member insertion portion 12 with the housing 11 of the connector device 10 being arranged and fixed on the wiring board, as shown in FIG. 7 and FIG. The actuator 15 provided in 10 has a first stationary position, and a plurality of contact terminal portions 43 and a plurality of contact terminal portions 44 in the terminal plate portion 42 of the FPC 40 inserted into the housing 11 are arranged. The portion is positioned in the housing 11, and the portion of the terminal plate portion 42 where the pair of engaging portions 46 and 47 are formed is also partially positioned in the housing 11.

  In such a case, when the FPC 40 is inserted into the housing 11 through the plate-like member insertion portion 12, the guide receiving portions 48 formed on the terminal plate portion 42 of the FPC 40 are attached to both ends of the housing 11 in the contact arrangement direction. Of the pair of engaging members 20 and 21, the abutting guide portion 27 formed by the elastic movable arm-like portion 24 of the engaging member 20 abuts on and receives guidance from the abutting guide portion 27, and the FPC 40.
