  By the way, in the connector wiring structure of the flexible substrate shown in FIG. 4, the terminal portion 3c of the flexible substrate 3 and the terminal 5b of the connector portion 5 are separate from each other. Therefore, at the time of assembly, the terminal 5b of the connector part 5 is attached to the bottom of the lamp housing 2 with the attachment screw 6, and the rising piece 5f of the terminal 5b is soldered to the conductive pattern around the connection hole 3b. Accordingly, it is necessary to electrically connect the terminal portion 3 c of the flexible substrate 3 to the terminal 5 b of the corresponding connector portion 5. Furthermore, when connecting a plurality of wirings, it is necessary to provide the number of terminals 5b corresponding to the number of wirings, and the above-described screwing work and soldering work are required for each terminal 5b. Therefore, as the number of assembly steps increases, the assembly time becomes longer. Further, the assembly cost increases due to the increase in the number of parts. Further, in order to ensure insulation between the individual terminals 5b, it is necessary to maintain a spatial distance between the terminals 5b. Accordingly, the width of the connector portion 5 is increased.

  Furthermore, at the bottom of the lamp housing 2, it is necessary to use a mounting screw 6 having a length corresponding to the mounting strength in order to secure the mounting strength of the terminal 5b. For this reason, the boss portion 2 d for receiving the mounting screw 6 needs to be longer than the thickness of the bottom portion of the lamp housing 2. As a result, the boss portion 2d protrudes below the lamp housing 2, and a space for the boss portion 2d is required on the lower side of the lamp housing 2.

  On the other hand, in the wiring structure according to Patent Document 1 and Patent Document 2, electrical connection by pressure contact between the conductive portion of the flexible substrate and the terminal of the connector portion is ensured by screwing for each terminal. For this reason, a fixing screw and attachment work are required for each terminal. Accordingly, the number of parts increases and the number of assembly steps increases, which increases the cost.

  Moreover, in the illuminating device by patent document 3, the electrical connection between a rigid board | substrate and a flexible substrate is performed by soldering via a relay component. For this reason, relay parts and soldering work are required for each terminal. Accordingly, the number of parts increases and the number of assembly steps increases, which increases the cost.

  Moreover, in the garnish of the back panel for vehicles by patent document 4, when the terminal part printed on the flexible printed circuit board contacts the contact bending piece of the terminal metal fitting to which the wire harness was connected and fixed, The wire harness is electrically connected. According to FIG. 5 and FIG. 6 of Patent Document 4, three contact bent pieces are provided side by side with respect to one elongated terminal portion of the flexible printed circuit board, and the shape thereof is complicated. For this reason, the terminal fitting having the contact bent piece has a large number of manufacturing steps and is expensive.

  Further, the reinforcing member for reinforcing the terminal portion of the flexible printed circuit board is positioned with respect to the terminal portion of the flexible printed circuit board so as not to be displaced when the terminal portion of the flexible printed circuit board is inserted into the terminal fitting. It is necessary to fix it, and the assembly work becomes complicated. Furthermore, since one wide reinforcing member is attached to a plurality of terminal portions arranged adjacent to each other, it is difficult to provide a reinforcing member at a portion where the contact bent piece of the terminal fitting is engaged. Therefore, sufficient reinforcement cannot be performed. On the other hand, when a separate terminal portion is welded to the conductive pattern of the flexible printed circuit board, the number of parts is increased, and welding work is required, resulting in high part costs and assembly costs. .

  In view of the above, an object of the present invention is to provide a connector connection structure of a flexible board that can be easily assembled with a simple configuration with a small number of components.

This is achieved by the board connector connection structure.

  In this 1st aspect, each connection terminal of a connector part is comprised integrally with a flexible substrate as an extension part of each terminal part of a flexible substrate. Therefore, the work for electrically connecting each connection terminal of the connector part to the corresponding terminal part of the flexible substrate by soldering, welding, or the like becomes unnecessary. Accordingly, the number of parts is reduced and the assembling work is simplified, so that the part cost and the assembling cost can be reduced. In that case, since each connection terminal of the connector part comprised as a part of flexible substrate is backed by the reinforcement member, when the said connector part is connected with the connector part which should become a pair, the connection terminal is Without deformation, the corresponding connection terminals of both connector portions can reliably contact each other and be electrically connected.

The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

  FIG. 1 shows the configuration of a vehicular lamp provided with an embodiment of a flexible board connector connecting structure according to the present invention. In FIG. 1, a vehicular lamp 10 includes a lamp housing 11, a flexible substrate 12 disposed in the lamp housing 11, and a reinforcing member 15 formed so as to follow the shape of one end edge of the flexible substrate. And a lens 13 covering the opening 11 a of the lamp housing 11, a grommet 23, and a connector portion 14 formed by the lamp housing 11 and the grommet 23.

  The lamp housing 11 is made of, for example, a resin material, and includes an opening 11a in a region in the light irradiation direction. The opening 11 a is hermetically sealed by the lens 13. The flexible substrate 12 has a known configuration, and includes, for example, a substrate made of a resin film having a thickness of about 0.1 mm and a conductive pattern that constitutes a circuit formed on the substrate, and serves as a light source. Electronic components (not shown) such as LEDs and resistors are mounted.

  Further, as shown in FIG. 2, the flexible substrate 12 has one end edge inclined, and includes an attachment hole 12 a and a connection terminal portion 12 b in the vicinity of the one end edge. As shown in FIG. 1, when the mounting hole 12a is disposed at a predetermined position in the lamp housing 11, a projection 11b provided at the bottom of the lamp housing 11 is fitted, and the projection 11b is formed by a heat caulking 11c. By being deformed, the flexible substrate 12 is fixedly held at a predetermined position in the lamp housing 11. In the illustrated case, the mounting hole 12a is provided for each terminal portion 12c including a plurality (two in the illustrated example) of conductive patterns provided in the vicinity of the edge on one side of the flexible substrate 12.

  The connection terminal portion 12b is provided for each terminal portion 12c of the flexible substrate 12, extends in a strip shape from one end of the flexible substrate 12, and is used as a connection terminal of the connector portion 14 described later. The Here, each connection terminal portion 12b is provided with a conductive pattern (not shown) extending integrally from the conductive pattern constituting each terminal portion 12c of the flexible substrate 12, and is electrically connected to each terminal portion 12c. Yes.

  Further, a connector portion 14 for the flexible substrate 12 is provided on one side (right side in FIG. 1) of the lamp housing 11. The connector portion 14 includes a connector housing 14a and a connection terminal (the connection terminal portion 12b) provided in the connector housing 14a, and constitutes a male connector as a whole.

  The connector housing 14a is configured integrally with the lamp housing 11, and the distal end side opposite to the lamp housing 11 is open to receive a female connector 20 described later. Further, the connector housing 14a has a through hole 14b through which the connection terminal portion 12b is inserted at the innermost portion.

  Here, the flexible substrate 12 is backed by a reinforcing member 15 as shown in FIG. 2 in the vicinity of the edge on one side and in the region of each connection terminal portion 12b. The reinforcing member 15 is made of an insulating material such as plastic, and has a base portion 15a attached in close contact with the back surface of one end edge of the flexible substrate 12 and extends obliquely downward from one side of the base portion 15a. And an elongated terminal reinforcing portion 15b.

  The base portion 15 a has the same width as an edge on one side of the flexible substrate 12, and includes an attachment hole 15 c at a position corresponding to the attachment hole 12 a of the flexible substrate 12. Moreover, the terminal reinforcement part 15b is arrange | positioned under each connection terminal part 12b of the flexible substrate 12, and is attached by adhesion | attachment, adhesion, etc. Thereby, each connection terminal part 12b of the flexible substrate 12 is backed by the terminal reinforcement part 15b of the reinforcement member 15, and the rigidity is improved.

  Thereby, the reinforcing member 15 is in a state where each connection terminal portion 12b of the flexible substrate 12 is inserted into the through hole 14b of the connector housing 14a together with the terminal reinforcing portion 15b of the reinforcing member 15, and the flexible substrate 12 and the reinforcing member 15 are connected to the lamp. When the projection 11b provided at the bottom of the lamp housing 11 is aligned and fitted into the mounting hole 12a and the mounting hole 15c when the base 11 is brought to a predetermined position on the bottom of the housing 11, the bottom of the lamp housing 11 is fitted. The flexible substrate 12 and the reinforcing member 15 are fixedly held at a predetermined position in the lamp housing 11 by being positioned at a predetermined position and the convex portion 11b being deformed by the heat caulking 11c.

  The vehicular lamp 10 having the flexible board connector connecting structure according to the present invention is configured as described above and is assembled as follows. That is, first, the reinforcing member 15 is attached to the vicinity of one edge of the flexible substrate 12 and the back surface of each connection terminal portion 12b by a fixing member such as an adhesive, an adhesive, or a double-sided tape. As a result, the vicinity of one edge of the flexible substrate 12 and the connection terminal portions 12b are lined up, and the rigidity is increased.

  Next, the connection terminal portion 12b of the flexible substrate 12 constituting the connection terminal of the connector portion 14 is inserted into the corresponding through hole 14b of the connector housing 14a from the lamp housing 11 side together with the terminal reinforcement portion 15b of the reinforcing member 15. Subsequently, the flexible substrate 12 is brought to a predetermined position on the bottom of the lamp housing 11. At this time, the mounting hole 12a of the flexible substrate 12 and the mounting hole 15c of the reinforcing member 15 are aligned with the convex portion 11b provided at the bottom of the lamp housing 11, and the convex portion 11b is fitted into the mounting holes 12a and 15c. As a result, the flexible substrate 12 is positioned at a predetermined position on the bottom of the lamp housing 11.

  In this state, the convex portion 11b is deformed and crushed by heat, so that the flexible substrate 12 is fixed to the bottom portion of the lamp housing 11 by heat caulking 11c. This completes the assembly. In this case, since the connection terminal of the connector part 14 is constituted by the connection terminal part 12b formed integrally with the flexible substrate 12, the number of parts is reduced, and soldering or Work such as screwing is unnecessary.

  The vehicular lamp 10 assembled in this way is connected to a female connector 20 attached to the tip of the corresponding wire harness 7 as shown in FIG. That is, the female connector 20 has substantially the same configuration as the connector 8 shown in FIG. 6, and includes a connector housing 21 and terminals 22 provided in the connector housing 21.

  The connector housing 21 is formed in a hollow shape whose front end is open, and has a hollow protrusion 21a at the center. The size of the inner wall of the hollow portion of the connector housing 21 is selected so as to contact the outer surface of the connector housing 14a of the connector portion 14 described above. Further, a grommet 23 is disposed outside the protruding portion 21 a of the connector housing 21. The grommet 23 is interposed between the outer surface of the protruding portion 21a of the connector housing 21 and the inner surface of the connector housing 14a of the connector portion 14, and prevents the protruding portion 21a from rattling within the connector housing 14a.

  The terminal 22 is disposed in the hollow portion of the protruding portion 21a of the connector housing 21, has a front end formed in a long and narrow plate shape, and comes into contact with one surface of the connection terminal portion 12b. This abutting portion has a convex portion 22a on the surface facing the connection terminal portion 12b, and the convex portion 22a abuts on one surface of the connection terminal portion 12b to be electrically connected. Moreover, the front end of the wire harness 7 inserted from the rear end of the connector housing 21 is connected to the rear end of the terminal 22 by soldering or the like.

  Therefore, when the connector part 14 of the vehicular lamp 10 is connected to the female connector 20, the connection terminal part 12 b of the flexible substrate 12 as the connection terminal of the connector part 14 is opposed to the terminal 22 of the female connector 20. And contacts the convex portion 22a of the terminal 22. Thereby, the connection terminal part of the flexible substrate 12 and the terminal 22 of the female connector 20 are electrically connected to each other. At this time, the connection terminal portion 12 b of the flexible substrate 12 is constituted by a part of the flexible flexible substrate 12, but the rigidity is sufficiently enhanced by the reinforcing member 15. Therefore, when inserted into the female connector 20, it can be reliably inserted without buckling or deformation. Thereby, the electrical connection between the connection terminal portion 12b of the flexible substrate 12 and the terminal 22 of the female connector 20 can be reliably performed.

  According to the vehicular lamp 10 having such a configuration, since the connection terminals of the connector portion 14 for connecting each terminal portion 12c of the flexible substrate 12 to an external circuit or the like are integrally formed with the flexible substrate 12, the connector The work for electrically connecting each connection terminal of the portion 14 to the corresponding terminal portion 12c of the flexible substrate 12 becomes unnecessary, the number of parts is reduced, and the number of assembly steps is reduced. Can be reduced.

  Further, since a mounting screw is not required for fixing the connection terminal of the connector portion 14 to the lamp housing or the connector housing, a boss portion for receiving the mounting screw is not required, and the lamp housing or the connector housing is configured to be smaller. And requires less space. Furthermore, since the connection terminal (connection terminal part 12b) of the connector part 14 comprised by a flexible substrate is backed by the terminal reinforcement part 15b of the reinforcement member 15, rigidity is improved and the electrical connection with respect to the female connector 20 is carried out. Can be done reliably.

  In the embodiment described above, the reinforcing member 15 is fixed to the back surface of the flexible substrate 12 by the fixing means. However, the present invention is not limited to this, and the reinforcing member 15 is provided at a predetermined location on the bottom of the lamp housing 11 by the mounting hole 15c. Are fixed by thermal caulking, and thus may not be fixed to the back surface of the flexible substrate 12. That is, fixing means such as an adhesive, an adhesive, and a double-sided tape can be omitted.

  In the above-described embodiment, the flexible substrate 12 includes the two terminal portions 12c and the connection terminal portion 12b. However, the present invention is not limited to this, and the flexible substrate 12 includes one or three or more terminal portions 12c and It is obvious that the connection terminal portion 12b may be provided. In this case, since each connection terminal portion 12b is configured integrally with the flexible substrate 12, an operation for electrically connecting each connection terminal portion 12b to the corresponding terminal portion 12c of the flexible substrate 12 is unnecessary. Therefore, even when the number of connection terminals is large, the number of parts is small, and assembly can be easily performed.

  Furthermore, in embodiment mentioned above, although the terminal reinforcement part 15b of the reinforcement member 15 has the same shape as the corresponding connection terminal part 12b which should be reinforced, not only this but the terminal reinforcement part 15b respond | corresponds. It may be formed larger than the connection terminal portion 12b. In this case, even if the connection terminal portion 12b is deformed and comes into contact with the adjacent connection terminal portion 12b for some reason, the conductive patterns of the adjacent connection terminal portions 12b come into contact with each other due to the presence of the terminal reinforcing portion 15b. Can be prevented.

  In this way, according to the present invention, it is possible to provide a connector connection structure for a flexible board with a simple configuration that has a small number of parts and can be easily assembled.
