  As shown in FIG. 2, the two conductor exposure openings 43 provided for each conductor 41 are provided apart from each other by a distance L2 in the cable length direction. The two conductor exposed openings 43 provided for each conductor 41 are arranged so that each conductor exposed opening 43 is formed on the outer surface 31 a of each rib 31 when the flat cable 4 is put on the pair of ribs 31.

The holding portion 58 is a dedicated protrusion that holds the flat cable 4 against the rib 31.

  The short-circuit conductor portion 56 described above is formed by forming a metal layer on the slope of the holding portion 58 that is continuous with the slope of the conductor contact portion 53.

  In the joint connection structure of this embodiment, a joint connection part is formed in the procedure shown in FIG.

  First, as shown in FIG. 4A, the flat cable 4 is put on the pair of ribs 31. At this time, the position of the flat cable 4 is adjusted so that each conductor exposure opening 43 on the flat cable 4 is positioned on the outer surface 31 a of the pair of ribs 31.

  Next, as shown by an arrow Y <b> 1 in FIG. 4B, the clip 5 is assembled to the pair of ribs 31 from above the flat cable 4 that covers the pair of ribs 31.

  Next, as shown in FIG. 4 (c), when the clip 5 is pushed into the base side of the pair of ribs 31 and the position of the conductor contact portion 53 is adjusted to the position of the conductor exposure opening 43 of the flat cable 4, the conductor contact portion 53 is in contact with the conductor 41 of the flat cable 4, the conductor contact portions 53 and the conductor 41 are in a conductive state, and the conductor contact portions 53 of the clip 5 are connected to each other by the short-circuit conductor portion 56. Thus, a joint connection portion in which the conductors 41 of the flat cable 4 are conductively connected is formed.

  Further, the flat cable 4 is fixed to the pair of ribs 31 by the force with which the conductor contact portion 53 of the clip 5 presses the conductor 41 against the rib 31 and the force with which the holding portion 58 presses the flat cable 4 against the rib 31. A state in which the connecting portion is fixed to the housing 3 is obtained.

  According to the joint connection structure of the embodiment described above, when the flat cable 4 placed on the rib 31 is fixed to the rib 31 by the clip 5, the plurality of conductor contact portions 53 provided on the clip 5 are arranged on the flat cable 4. A joint in which the conductors 41 on the flat cable 4 are brought into contact with each other through the conductor exposed openings 43 and the conductors 41 on the flat cable 4 are connected to each other by the conductor contact portion 53 and the short-circuit conductor portion 56 on the clip 5. A connection is formed.

  That is, a joint connection portion in which a plurality of conductors 41 are conductively connected can be formed by a simple operation of assembling the clip 5 to the rib 31 covered with the flat cable 4. Further, a complicated part such as a housing in a conventional joint connector is not required.

  In addition, since the joint connection portion is formed on the rib 31 erected on the housing 3 of the routing destination, the fastening work to the housing 3 is not necessary, and the joint connection portion is formed simultaneously with the formation of the joint connection portion. Therefore, the joint connection portion can be easily fixed to the casing 3 as the routing destination.

  Further, according to the joint connection structure of the embodiment, the clip 5 is configured to sandwich the pair of ribs 31 that are separated in the direction in which the flat cable 4 is routed. Since it is too thin, stable clamping cannot be performed, the contact pressure between the conductor contact portion 53 of the clip 5 and the conductor 41 of the flat cable 4 at the joint connection portion can be stabilized, and a stable conductive connection state can be obtained. The reliability with respect to the conductive connection can be improved.

  In addition, according to the joint connection structure of the embodiment, the contact between the conductor contact portion 53 of the clip 5 and the conductor 41 of the flat cable 4 is realized at two locations separated in the wiring direction of the flat cable 4. Contact between the conductor contact portion 53 of the clip 5 and the conductor 41 of the flat cable 4 can be reliably ensured, and the reliability of joint connection can be improved.

  Further, according to the joint connection structure of the embodiment, the pair of sandwiching pieces 51 sandwiching the rib 31 presses the flat cable 4 against the rib 31 separately from the conductor contact portion 53 that press-contacts the conductor 41 of the flat cable 4. Thus, the presser portion 58 fixed to the rib 31 is provided, and the conductor contact portion 53 and the presser portion 58 can set the pressing force independently of each other.

  In other words, the conductor contact portion 53 can be set with a pressing force suitable for an electrically conductive connection, and the pressing portion 58 can be set with a pressing force suitable for fixing, while realizing a stable joint connection, The joint connection portion can be firmly fixed to the housing 3.

  In addition, according to the joint connection structure of the embodiment, the conductor contact portion 53 and the short-circuit conductor portion 56 of the clip 5 are metal layers formed on the inner surfaces of the pair of sandwiching pieces 51 that sandwich the rib 31, for example, It can be formed by plating, etc., the material of the clip 5 body can be selected from synthetic resin, and the material of the clip 5 body can be selected by selecting a synthetic resin that is lighter and less expensive than metal. 5 can be reduced in weight and cost.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above-described embodiment, the housing 3 and the rib 31 may be made of metal or synthetic resin.

  However, when the rib 31 is formed of a conductive material and connected to a ground terminal or the like, the plurality of conductor contact portions 53 are conductively connected to the rib 31 when the clip 31 is assembled to the rib 31. It is also conceivable to provide a rib contact portion made of a conductive material.

  In this case, the rib contact portion has, for example, a projection shape similar to that of the conductor contact portion 53, and the rib contact portion is formed of the conductive material rib 31 through a through-hole penetrating the insulator layer of the flat cable 4. It is preferable to have a configuration in contact with the surface.

  Thus, when the clip 5 is assembled to the rib 31 covered with the flat cable 4, the plurality of conductors 41 of the flat cable 4 are electrically connected to each other, and at the same time, the plurality of conductors 41 of the flat cable 4 are connected to the rib contact portion. Also, the rib 31 is conductively connected via.

  Therefore, when the rib 31 is conductively connected to a vehicle body or the like that is a structural material for grounding, the plurality of conductors 41 of the flat cable 4 joint-connected by the clip 5 are grounded to the rib 31 and the joint connection for grounding is performed. The part can be formed.

  And, by simply assembling the clip 5 to the rib 31, the ground connection is realized, and compared with the case where the conductor 41 is fastened to the ground terminal by screwing, a dedicated fastening part is unnecessary, and the number of parts at the time of ground connection can be reduced. The number of work processes can be reduced.

  Further, when the clip 5 is configured to be conductively connected to the rib 31, it is possible to detect the drop of the clip 5 by the conduction check.

  In the above-described embodiment, the clip 5 is configured to sandwich the pair of ribs 31. However, the clip 5 may be configured to sandwich the single rib 31. By doing in this way, a joint connection part can be made compact.

  Further, the conductor exposure opening 43 provided for each conductor 41 of the flat cable 4 can be made single.

  Further, in the above-described embodiment, in order to fix the flat cable 4 to the rib 31, the dedicated pressing portion 58 is provided separately from the conductor contact portion 53. However, in the case where sufficient pressing force for fixing the flat cable 4 to the rib 31 can be obtained with the conductor contact portion 53 alone, the conductor contact portion 53 can also be used as the pressing portion 58. In such a case, the configuration of the clip 5 can be simplified by omitting the dedicated presser 58.

[Other Embodiments]
Next, another embodiment of the present invention will be described. The present embodiment is an example of a joint connection structure that does not use a flat cable. In the present embodiment, the conductors of the circuit bodies provided in the housing are joint-connected by clips.

  As shown in FIG. 5, in order to provide the casing 203 with the circuit body 133, the conductor 130 constituting the circuit body 133 may be formed by printing. However, as shown in FIG. 5, when the rib 131 is erected on the housing 203, the movement of the circuit printing nozzle 212 for printing the circuit body 133 is restricted by the rib 131. Therefore, the conductor 130 cannot be printed in the region between the ribs 131. As a result, the conductor 130 is printed only up to the vicinity of the rib 131, and the conductor 130 is divided by the rib 131.

In order to prevent the conductor 130 from being divided by the rib 131, it is necessary to delete the rib 131 in the conductor forming region as shown in FIG. Therefore, there is a problem that a step of cutting the rib 131 before the conductor 130 is printed is added, and the manufacture of the circuit body 133 is complicated.
Such a problem can be solved by the following embodiment.

  As shown in FIG. 7, the joint connection structure of the present embodiment includes a housing 203, a pair of ribs 131 erected on the housing 203, and a clip that is fixed to the ribs 131 by sandwiching the ribs 131. 105, and a circuit body 133 that is provided on the housing 203 and has a conductor 130 that extends in a direction orthogonal to the extending direction of the rib 131 and is disposed outside the rib 131. The clip 105 includes a plurality of conductor contact portions 154 that are made of a conductive material and are in contact with the conductor 130 when assembled to the rib 131, and a short-circuit conductor portion 156 that electrically connects the plurality of conductor contact portions 154 to each other. Yes. In the joint connection structure of the embodiment, the clip 105 is fixed to the rib 131 to realize conduction connection between the conductors 130 outside the rib 131.

  The pair of ribs 131 erected on the housing 203 are opposed in parallel. Each rib 131 is formed with a locking hole 132 on the front side and the back side in FIG.

  On the housing 203, two rows of conductors 130 constituting the circuit body 133 are printed on both sides of the rib 131. The conductor 130 is applied onto the housing 203 by the circuit printing nozzle 212 and printed. The conductors 130 on both sides of the rib 131 are arranged on the same straight line via the rib 131.

  The clip 105 is formed of a conductive material, a pair of sandwiching pieces 151 that are in contact with the outer surfaces 131a of the pair of ribs 131, and a connecting portion 152 that connects one side edges of the pair of sandwiching pieces 151; It has. The connecting portion 152 couples the pair of sandwiching pieces 151 so that the pair of sandwiching pieces 151 sandwich the surfaces 131a of the pair of ribs 131 that are outside each other. In other words, the clip 105 sandwiches the surfaces 131 a of the pair of ribs 131 that are outside each other by the pair of sandwiching pieces 151. In the case of this example, the connecting portion 152 also serves as the short-circuit conductor portion 156.

  Each clamping piece 151 of the clip 105 has a locking projection 153 that is locked to a locking hole 132 formed in the pair of ribs 131. In each clamping piece 151, the locking protrusions 153 are provided on the near side and the far side in FIG. The clip 105 is securely fixed to the rib 131 by the locking projection 153 of the holding piece 151 being locked in the locking hole 132 of the rib 131.

  In addition, each sandwiching piece 151 of the clip 105 has a conductor contact portion 154 that can contact the conductor 130 constituting the printed circuit on the housing 203. The conductor contact portion 154 is made of a curved spring member and elastically contacts the conductor 130. The conductor contact portion 154 may be formed integrally with the holding piece 151 or may be added to the holding piece 151 later.

  When the clip 105 sandwiches the pair of ribs 131 and is fixed to the ribs 131, each conductor contact portion 154 comes into contact with the conductor 130 on the housing 203. Each conductor 130 is electrically connected to each other by the clip 105 that is in contact via the conductor contact portion 154. In the example illustrated in FIG. 7, the clip 105 includes four conductor contact portions 154 that respectively contact the four conductors 130. Thereby, the conductors 130 on both sides of the rib 131 are electrically connected to each other as schematically shown in FIG.

  When the clip 105 has three conductor contact portions 154, the three conductors 130 are electrically connected as schematically shown in FIG. 8B.

  The number of conductor contact portions 154 can be set according to the number of conductors 130 to be distributed as the same potential.

  Next, a method for connecting the conductors 130 on the housing 203 with the clip 105 will be described. As shown in FIG. 9A, the conductor 130 constituting the circuit body 133 is applied on the casing 203 on both sides of the pair of ribs 131 by printing. As shown in FIG. 9B, when the clip 105 is pushed over the pair of ribs 131 from above and pushed down, the locking projection 153 of the clip 105 enters the locking hole 132 of the rib 131 as shown in FIG. 9C. Locked. As a result, the clip 105 is fixed by sandwiching the pair of ribs 131. At this time, each conductor contact portion 154 of the clip 105 contacts each conductor 130 on the housing 203. As a result, the conductors 130 separated in the region between the ribs 131 are electrically connected to have the same potential.

  According to the present embodiment, even if the conductor 130 is divided by the pair of ribs 131, the conductors 130 on both sides of the rib 131 can be easily connected to each other by fixing the clip 105 to the rib 131. Therefore, circuit formation on the housing 203 having the ribs 131 is facilitated.

  Further, as shown in FIG. 10, the clip 105 can be provided with a bulb 140 for illumination.
