In addition, the guide frame 17 is formed as a member having a rigidity that does not easily bend when the weight of the FPC 16 with a circuit body side connector or the connector is connected. As described above, the guide frame 17 is used to collectively connect the FPCs 16 with circuit body side connectors to the device side connectors 4 of the five solenoid valves 1.

  The guide frame 17 has a frame body 28. A plurality (10 in this embodiment) of FPC holding portions 29 (circuit body holding portions) are formed on the upper surface of the frame main body 28. Further, the five FPC holding portions 29 arranged on the side closer to the circuit body side connector 20 among the plurality of FPC holding portions 29 are respectively formed so that the connector push-out portions 30 are continuous. As described above, the guide frame 17 includes the FPC holding portion 29 and the connector pushing portion 30 in the frame main body 28. A more detailed explanation is given below.

  The frame body 28 is formed in a band plate-like portion. The left and right end portions 31 (the left end portion 31 and the right end portion 31) of the frame main body 28 are formed as portions guided by being inserted into the slit portions 11 of the pair of positioning portions 8.

  The FPC holding unit 29 is a part that holds the terminal (branch line part 22) of the FPC 19, and is provided at least two for one terminal of the FPC 19. In this embodiment, two are provided. The two FPC holding portions 29 are arranged at a staggered position on both the left and right sides of the terminal (branch line portion 22) of the FPC 19. Of the two FPC holding portions 29, the FPC holding portion 29 on the side close to the circuit body-side connector 20 is arranged in accordance with the position of the edge portion of the frame main body 28.

The other FPC holding portion 29 is arranged in accordance with the position of the T-shaped portion, thereby providing an effect that it can contribute to positioning of the FPC 19 and stabilization of the arrangement of the FPC 19.

  The FPC holding part 29 has a circuit body mounting surface 34 and a protruding part 35 and is formed in the illustrated shape. The circuit body mounting surface 34 is formed as a flat surface on which the terminal (branch line portion 22) of the FPC 19 is mounted. The protruding portion 35 is formed as a portion protruding upward from the circuit body mounting surface 34. The protrusion 35 is formed in a substantially rib-like portion extending in the front-rear direction. The protruding portion 35 is formed as a portion that holds the terminal (branch line portion 22) of the FPC 19. Such a protrusion 35 is formed with a mounting surface facing portion 36 and an FPC insertion portion 37 (circuit body insertion portion). The protruding portion 35 is formed in a substantially inverted L shape by the mounting surface facing portion 36 and the FPC insertion portion 37.

  The protruding portion 35 is arranged and formed in a state in which a clearance C (see FIG. 7) is secured with respect to the left or right side portion of the terminal (branch line portion 22) of the FPC 19. That is, it is arranged and formed so as to absorb the positional deviation in the left-right direction.

  The mounting surface facing portion 36 is formed as a holding portion that faces the circuit body mounting surface 34 at a predetermined interval (with an interval larger than the thickness of the branch line portion 22). The FPC insertion portion 37 is formed as an opening that allows the terminal (branch line portion 22) of the FPC 19 to be inserted. The FPC insertion part 37 is formed as a slit-shaped part.

  2, 3, and 10, the connector push-out portion 30 is formed as a portion that can push out the circuit body-side connector 20 to a normal connector fitting position. As described above, the connector push-out portion 30 is formed so as to be continuous with the FPC holding portion 29 (the FPC holding portion 29 on the side close to the circuit body-side connector 20) arranged in accordance with the position of the front edge portion 32. Is done. The connector push-out part 30 is formed to have flexible elasticity (elasticity) so that the circuit body-side connector 20 can be pushed out (not limited to this embodiment, but elastic such as rubber or sponge). A member may be pasted and replaced by this). In the connector push-out portion 30 of the present embodiment, a continuous portion 38, an elastic portion 39, and a push-side contact portion 40 are formed.

  The elastic portion 39 is formed in a U-shaped and semi-cylindrical portion (the shape is an example and may be V-shaped or the like). The elastic part 39 has elasticity in the connector connection direction and is formed in a shape that bends uniformly in the connector connection direction. The extrusion-side contact portion 40 is formed as a portion that contacts the connector-side contact portion 27 at the rear of the circuit body-side connector 20. The extruding side contact portion 40 is disposed closer to the circuit body side connector 20 than the elastic portion 39. Such an extrusion-side contact portion 40 is formed in a shape that ensures contact with the connector-side contact portion 27 in the connector alignment direction. That is, the extrusion side contact portion 40 is formed in a shape extending in the connector arrangement direction.

  In FIG. 2, when the FPC 16 with a circuit body side connector and the guide frame 17 are prepared, and then the FPC 16 with a circuit body side connector is held by the guide frame 17, an FPC holding state guide frame 18 is obtained as shown in FIG.

  Regarding the holding, the FPC 16 with the circuit body-side connector has the trunk portion 21 of the FPC 19 placed on the trunk placement portion 41 of the guide frame 17.

  As can be seen from FIGS. 3 and 10, since the connector push-out portion 30 protrudes from the position of the front edge portion 32 toward the device-side connector 4, the guide frame 17 completes the holding of the FPC 16 with the circuit body-side connector. Then, the circuit body side connector 20 provided in the terminal (branch line part 22) of FPC19 will be in a free end state.

  In FIG. 5, when the left and right end portions 31 of the guide frame 17 in the FPC holding state guide frame 18 are inserted into the respective slit portions 11 of the pair of positioning portions 8 and are slid and moved, each circuit of the FPC 16 with the circuit body side connector is accompanied accordingly. The body-side connector 20 moves straight toward each device-side connector 4 of the solenoid valve 1 (see FIGS. 6 to 8).

  When connector fitting between the circuit body-side connector 20 and the device-side connector 4 is started (when connector connection is started), the connector-side contact portion 27 of the circuit-body-side connector 20 is brought into contact with the push-out side of the connector push-out portion 30. The part 40 contacts. Therefore, by the action of the connector push-out part 30 (by the action of the elastic part 39), the circuit body side connector 20 is pushed out to the fitting completion position (to the connection completion position) as shown in FIGS. Thus, the connector fitting (connector connection) is completed. Connector fitting (connector connection) is completed at five locations in this embodiment. That is, the collective connection is completed.

  In this embodiment, since the taper 42 is formed at the connector fitting start portion of the circuit body side connector 20 and the taper 43 is also formed at the connector fitting start portion of the device side connector 4, the circuit body side connector Of course, 20 can be guided to the normal fitting position of the device-side connector 4.

  When the guide frame 17 is removed after the collective connection is completed, a state as shown in FIG. 11 is obtained, and a series of connection work is completed.

  As described above with reference to FIGS. 1 to 11, according to the present invention, a plurality of connectors are collectively connected using the guide frame 17. Since a plurality of FPC holding portions 29 are formed to hold the terminals (branch line portions 22) of the FPC 19 while absorbing the positional deviation in the arrangement direction (left and right direction), the FPC holding side closer to the circuit body side connector 20 is also formed. When the connector 29 is misaligned in the connector arrangement direction and the connector connection direction, the connector push-out portion 30 that elastically contacts the circuit body-side connector 20 along the connector connection direction (front-rear direction) is formed in the portion 29. Even so, this positional shift can be absorbed and a batch connection can be made.

  Therefore, according to the present invention, there is an effect that it is possible to easily perform collective connection even when manufacturing positional deviation occurs.

  In addition, according to the present invention, the connector guiding taper 42, 43 is formed in the connector fitting start portion, so that the circuit body side connector 20 can be guided to the normal fitting position of the device side connector 4. .

  Therefore, according to the present invention, there is an effect that the connectors can be easily connected together.

  In addition, according to the present invention, the FPC holding portion 29 in which the connector push-out portion 30 is continuous is arranged in accordance with the position of the front edge portion 32 of the guide frame 17, so that the edge portion 32 and the circuit body side connector 20 A space S (see FIG. 10) is generated between the two, and this space S can be used as a bending allowable space of the terminal (branch line portion 22) of the FPC 19.

  Therefore, the arrangement described above can contribute to absorption of displacement in the connector connection direction (front-rear direction).

  It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.

  For example, the present invention is not limited to the above description, and the connector push-out portion 30 is protruded from the surface opposite to the circuit body mounting surface 34 or the front edge 32, and the terminal (branch line) of the FPC 19 is located at the position of the connector push-out portion 30. It is also possible to adopt a structure in which the portion 22) is on the top and the connector push-out portion 30 is on the bottom. That is, the structure which supports the circuit body side connector 20 in the connector extrusion part 30 may be sufficient. It is effective if there is a concern about the sagging of the circuit body side connector 20.

  Since the sag can be prevented while the circuit body side connector 20 is at the free end, the connector can be easily connected together.

  As other modifications, examples shown in FIGS. 12 and 13 can be given. Hereinafter, a modification of the branch line portion 22 in the FPC 19 will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram showing a modification when the circuit width of the branch line portion 22 is the same, and FIG. 13 is a diagram showing a modification when the circuit width is narrow. In the description here, the shape of the branch line portion 22 is only partially different from the example of FIGS. 1 to 11, and therefore the same reference numerals other than the characteristic portions are attached and the description is omitted. And

  12 and 13, a portion corresponding to the terminal of the FPC 19, that is, the branch line portion 22 is formed with a positional deviation absorbing portion 44 that is one of the characteristic portions of the present invention. The positional deviation absorbing portion 44 is formed as a portion that can be displaced at least in the left-right direction (a portion that can be deformed), preferably as a portion that can also be displaced in the front-rear direction. In other words, it is formed as a portion that can absorb the misalignment that occurs. The misalignment absorbing portion 44 is formed in, for example, a substantially S-shaped and expandable shape (the shape is an example. The shape is not particularly limited as long as the misalignment can be absorbed). The misalignment absorbing portion 44 is disposed and formed so as to be positioned between the two FPC holding portions 29.

  In the above configuration and structure, when the FPC holding state guide frame 18 is slid, each circuit body side connector 20 of the FPC 16 with circuit body side connector moves straightly toward each device side connector 4 of the solenoid valve 1 along with the sliding movement. To do. When connector fitting between the circuit body-side connector 20 and the device-side connector 4 is started (when connector connection is started), the connector push-out portion 30 contacts the circuit body-side connector 20. Therefore, the circuit body side connector 20 is pushed out to the fitting completion position (to the connection completion position) by the action of the connector push-out portion 30. Thus, the connector fitting (connector connection) is completed.

  12 and 13, a taper 45 is formed at the connector fitting start portion of the device-side connector 4. Thereby, the circuit body side connector 20 can be guided to the regular fitting position of the apparatus side connector 4.

  According to the present invention of FIGS. 12 and 13, the misalignment absorbing portion 44 is formed in the branch line portion 22 as a portion capable of absorbing misalignment in the connector arrangement direction (left-right direction) and the connector connection method (front-rear direction). For this reason, this misalignment absorbing portion 44 can be contributed when performing batch connection related to connector fitting. In addition, according to the present invention, it is possible to facilitate work when holding the branch line portion 22 on the two FPC holding portions 29 of the guide frame 17 by utilizing the characteristics of the displaceable position shift absorbing portion 44. it can. That is, workability can be improved.
