However, in the lighting device described in Patent Document 1, the direct connector on the housing side and the external connector on the vehicle side are arranged inside the elastic member. That is, the terminal (first conductive member) of the direct connector and the conductor (second conductive member) of the external connector are electrically connected inside the elastic member.

The turn signal lamps (lighting devices) 10 shown in FIG. 1 are attached to the left and right sides in the front and rear of the motorcycle. Specifically, the winker lamp 10 is fixed to cowl stays provided on the left and right sides of the motorcycle via support members (not shown). The winker lamp 10 includes a lamp portion 30 , a wire harness 50 and an elastic member 70 .

Here, the elastic member 70 is formed in a cylindrical shape by injection molding an elastic material such as natural rubber, and extends in the longitudinal direction of the ramp portion 30 (horizontal direction in FIG. 1). More specifically, as shown in FIG. 2, the elastic member 70 extends in the communication direction of the communication hole 32f (the portion through which the wire harness 50 passes) of the housing 32 and forms a pair of wire harnesses 50. It covers the wiring 53 .

One longitudinal side (left side in FIG. 1) of the elastic member 70 is fixed to the other longitudinal side (right side in FIG. 1) of the ramp portion 30 (housing 32). On the other hand, the other longitudinal side of the elastic member 70 is fixed to a support member provided on the cowl stay. As a result, even if an obstacle comes into contact with the ramp portion 30, the elastic member 70 is flexibly elastically deformed, and damage to the ramp portion 30 is effectively suppressed.

The lamp part 30 includes a lens 31 made of a transparent and hard resin material, a housing 32 made of a hard resin material that does not transmit light such as black, and a substrate (PCB) mounted inside the housing 32. 33 and.

As shown in FIGS. 1 to 3, the lens 31 is formed in a substantially rectangular plate shape and faces a light source (LED) 33a mounted on the substrate 33. That is, the lens 31 is arranged on the substrate 33 on the side of the light source 33a. As a result, light is emitted from the light source 33 a toward the lens 31 and transmitted through the lens 31 to the outside. The lens 31 includes a lens body 31a formed in a substantially flat plate shape, and a plurality of uneven portions 31b are provided on the inner surface (housing 32 side) of the lens body 31a. These concave-convex portions 31b have a function of diffusing the light emitted from the light source 33a over a wide area outside the lens 31 .

A lens wall portion 31c erected from the lens body 31a toward the housing 32 is integrally provided on the outer peripheral portion of the lens body 31a. The tip side (housing 32 side) of the lens wall portion 31c is welded to the tip side (lens 31 side) of the housing wall portion 32b of the housing 32 by an infrared welding machine (not shown). As a result, the lens 31 is attached to the housing 32 in an airtight state, and rainwater, dust, and the like are reliably prevented from entering the interior of the lamp portion 30 .

For fixing the lens 31 and the housing 32, other fixing methods such as fixing with an adhesive or ultrasonic welding can be adopted instead of welding with an infrared welding machine. That is, as long as the airtight state between the lens 31 and the housing 32 is ensured, the fixing method does not matter.

As shown in FIGS. 1 to 4 (a) and (b), the housing 32 is formed in a substantially box shape with an opening on the lens 31 side. The housing 32 has a bottom wall portion 32a that faces the lens body 31a, and a housing wall portion 32b that rises from the bottom wall portion 32a toward the lens 31 is provided integrally with the outer peripheral portion of the bottom wall portion 32a. ing.

As shown in FIG. 4(a), the housing wall portion 32b has a first wall W1 and a second wall W2. The first wall W1 occupies most of the housing wall portion 32b and has a substantially C shape as viewed from arrow B in FIG. 1(b). On the other hand, the second wall W2 forms a part of the housing wall portion 32b and has a substantially I shape as viewed from arrow B in FIG. 1(b). Here, in FIG. 4A, the boundary between the first wall W1 and the second wall W2 is indicated by a dashed line. The second wall W2 partitions the inside and outside of the housing 32, and corresponds to the partition wall in the present invention.

As shown in FIGS. 2 and 4A, the bottom wall portion 32a of the housing 32 is integrally provided with one first support column 32c, one second support column 32d and a pair of third support columns 32e. is provided. These first, second, and

third support columns

32c, 32d, and 32e support the substrate 33 at their distal end portions. The substrate 33 is accommodated inside the housing 32 while being supported by the first, second, and

third support columns

32c, 32d, and 32e (see FIG. 2).

The first support column 32c is arranged on the side opposite to the second wall W2 side in the longitudinal direction of the housing 32, and extends from the bottom wall portion 32a toward the lens 31. The second support column 32d is arranged substantially in the center of the housing 32 in the longitudinal direction and extends from the bottom wall portion 32a toward the lens 31. As shown in FIG. Further, the pair of third support columns 32e are arranged in the longitudinal direction of the housing 32 closer to the second wall W2 than the second support columns 32d, and extend from the bottom wall portion 32a toward the lens 31. As shown in FIG. The pair of third support columns 32e are also integrated with the first wall W1.

A first fixing screw S1 can be screwed from the lens 31 side to the second support column 32d. The substrate 33 is firmly fixed to the housing 32 by the first fixing screw S1. The fixing of the substrate 33 to the housing 32 is not limited to the use of the first fixing screw S1. It is also possible to pinch the periphery and fix it by welding with an infrared welding machine in this state.

Here, as shown in FIG. 5, the substrate 33 is formed in a substantially rectangular plate shape, and the light source 33a is mounted substantially in the center of the mounting surface SF. In the vicinity of the light source 33a of the substrate 33, base ends of a pair of first conductive members 33b made of brass or the like having excellent conductivity are electrically connected by soldering or the like. The pair of first conductive members 33b are formed in a substantially L-shape, and their distal ends are directed to the communicating holes 32f provided in the second wall W2 of the housing 32 (see FIG. 2).

Further, screw insertion holes 33c are provided between the light source 33a and the pair of first conductive members 33b in the longitudinal direction of the substrate 33, and the screw insertion holes 33c are used for fixing the substrate 33 to the housing 32. 1 fixing screw S1 is inserted.

As shown in FIGS. 2 and 4(b), the second wall W2 forming the housing wall portion 32b has a communication hole 32f through which one longitudinal side (the right side in FIG. 2) of the wire harness 50 is inserted. is provided. The communication hole 32f is formed in a substantially elliptical shape and allows the inside and outside of the housing 32 to communicate with each other. A grommet 51 forming a wire harness 50 is inserted into the communication hole 32f (see FIG. 2).

Here, as shown in FIG. 6, the grommet 51 is formed in a substantially rectangular parallelepiped shape by injection molding an elastic material such as natural rubber. The grommet 51 has a grommet body 51a that is inserted into the communication hole 32f while being elastically deformed.

In addition, the grommet 51 includes a flange portion 51b that protrudes outward from the grommet body 51a and regulates the amount of insertion of the grommet body 51a into the communication hole 32f. Further, on the side opposite to the flange portion 51b side in the longitudinal direction of the grommet 51 (horizontal direction in FIG. 6), a hook portion 51c that protrudes outward from the grommet body 51a and is hooked on the second wall W2 is provided. ing.

A pair of wiring fixing holes 51d are provided inside the grommet 51, and these wiring fixing holes 51d penetrate the grommet 51 in the longitudinal direction. Ends of a pair of female terminals 52 forming the wire harness 50 are fixed inside the pair of wire fixing holes 51d and on one longitudinal side thereof (left side in FIG. 2). On the other hand, one longitudinal side of a pair of wires 53 forming the wire harness 50 is fixed inside the pair of wire fixing holes 51d and on the other longitudinal side (the right side in FIG. 2). That is, the pair of female terminals 52 and the pair of wires 53 are fixed inside the wire fixing holes 51d and electrically connected to each other. Therefore, even if the pair of wires 53 are pulled against the grommet 51, they will not come off easily.

Thus, the grommet 51 is provided between the pair of female terminals 52 and the pair of wires 53 and the housing 32 (communication hole 32f), and the pair of female terminals 52 and the pair of wires 53 and the housing 32 ( The communication hole 32f) is sealed. That is, the grommet 51 corresponds to the sealing member in the present invention.

The second wall W2 is integrally provided with a first fixed column 32g formed in a substantially cylindrical shape. The first fixed column 32g extends from the second wall W2 toward the elastic member 70 in the longitudinal direction of the housing 32 on the bottom wall portion 32a side of the communication hole 32f of the second wall W2. A second fixing screw S2 can be screwed from the elastic member 70 side in the longitudinal direction of the housing 32 to the first fixing column 32g. As a result, the support plate 34 made of a stainless steel plate is firmly fixed inside the housing 32 and on the distal end side (right side in FIG. 2) of the first fixing column 32g.

Here, as shown in FIG. 7, the support plate 34 is formed into a substantially rectangular shape by punching a stainless steel plate, and has a notch 34a and a screw hole 34b. Note that the support plate 34 is not limited to a stainless steel plate, and may be formed of a plate material such as hard plastic. A pair of wires 53 forming the wire harness 50 are inserted through the notch 34a, and a second fixing screw S2 is inserted through the screw hole 34b. As shown in FIG. 2, the support plate 34 supports the flange portion 51b of the grommet 51 inserted into the communication hole 32f and fixed to the housing 32 while the support plate 34 is fixed to the housing 32. As shown in FIG.

This reliably prevents the grommet 51 from slipping out of the communication hole 32f. In other words, the support plate 34 prevents the pair of wires 53 from coming off from the communication holes 32f, and corresponds to the retaining member in the present invention. Therefore, even if the wire harness 50 is pulled when fixing the winker lamp 10 to the cowl stay support member (vehicle side), the wire harness 50 is prevented from coming off from the housing 32 .

Instead of the support plate 34 fixed to the housing 32 by the second fixing screw S2, for example, the grommet 51 attached to the communication hole 32f can be fixed by covering it with a mold resin (not shown). . In this case, the mold resin corresponds to the retaining member in the present invention. In short, other retaining members can be used as long as they can retain the grommet 51 attached to the communication hole 32f.

A second fixed column 32h formed in a substantially cylindrical shape is integrally provided with the second wall W2. The second fixing column 32h is larger than the first fixing column 32g, and extends from the second wall W2 in the longitudinal direction of the housing 32 on the lens 31 side (the upper side in FIG. 4B) of the communication hole 32f of the second wall W2. at the elastic member 70 side. A third fixing screw S3 (see FIG. 2) can be screwed to the second fixing column 32h from the elastic member 70 side in the longitudinal direction of the housing 32. As shown in FIG. As a result, the elastic member 70 is firmly fixed to the housing 32 via the fixing plate PL (see FIG. 2). The fixing plate PL is provided with an insertion hole H through which the third fixing screw S3 is inserted and a notch groove G through which the pair of wires 53 are inserted (see FIG. 3).

Here, as shown in FIG. 2, the wire harness 50 is provided between the lamp section 30 and the vehicle-mounted controller (power supply) CU to supply the lamp section 30 with power. The wire harness 50 includes the grommet 51, the pair of female terminals 52, and the pair of wires 53 as described above, and further includes the connector connecting portion 54 formed in a substantially box shape.

The connector connection portion 54 is fixed to the other longitudinal side of the pair of wires 53, and the connector connection portion 54 is connected to an external connector (not shown) on the vehicle side. As a result, power is supplied from the vehicle-mounted controller CU to the light source 33a mounted on the substrate 33, so that the light source 33a blinks.

Here, the pair of female terminals 52 and the pair of wires 53 forming the wire harness 50 correspond to the second conductive member in the present invention. Moreover, the female terminal 52 corresponds to the connection terminal in the present invention. Further, the portion of the pair of female terminals 52 on one side in the longitudinal direction of the wire harness 50 corresponds to the tip portion, and the portion of the connector connecting portion 54 on the other side in the longitudinal direction of the wire harness 50 corresponds to the base end portion.

Next, the procedure for assembling the winker lamp 10 formed as described above will be described in detail with reference to the drawings.

As shown in FIG. 3, first, various parts are prepared which are respectively formed through separate manufacturing processes in advance. Specifically, the lens 31, housing 32, substrate 33 and first fixing screw S1 are prepared. Also, the wire harness 50, the support plate 34 and the second fixing screw S2 are prepared. Furthermore, the elastic member 70, the fixing plate PL and the third fixing screw S3 are prepared.

The substrate 33 faces the opening side of the housing 32 (upper side in FIG. 3) as indicated by the arrow M1. At this time, the tip portions of the pair of first conductive members 33 b connected to the substrate 33 are directed toward the communication holes 32 f of the housing 32 . The surface (rear surface) of the substrate 33 opposite to the mounting surface SF is placed on the first support column 32c, the second support column 32d and the third support column 32e of the housing 32. As shown in FIG. Next, as indicated by an arrow M2, the substrate 33 is fixed to the housing 32 by screwing the first fixing screw S1 to the second support column 32d.

After that, the housing 32 with the board 33 assembled is set in an infrared welding machine (not shown). Then, the lens 31 is placed on the housing 32 so that the lens 31 faces the opening side of the housing 32 as indicated by an arrow M3. At this time, the lens wall portion 31 c of the lens 31 is brought into contact with the housing wall portion 32 b of the housing 32 . Next, the infrared welding machine is operated to weld the front end side of the lens wall portion 31c and the front end side of the housing wall portion 32b to seal them. This completes the assembly of the ramp portion 30 (the sub-assembly surrounded by the dashed line in FIG. 2).

Next, the pair of female terminals 52 side of the wire harness 50 in the longitudinal direction is faced from the outside of the housing 32 toward the communication hole 32f of the housing 32 in the lamp portion 30, as indicated by an arrow M4. Then, the grommet 51 is pressed with a predetermined pressing force, and the grommet body 51a (see FIG. 6) of the grommet 51 is inserted into the communication hole 32f.

At this time, the hook portion 51 c (see FIG. 6) of the grommet 51 is exposed inside the housing 32 and the flange portion 51 b of the grommet 51 is brought into contact with the housing 32 . Thereby, inside the housing 32, the pair of female terminals 52 are electrically connected to the tip portions of the pair of first conductive members 33b (corresponding to male terminals), respectively. In addition, since the grommet body 51a is inserted straight into the communication hole 32f while being restricted, the pair of female terminals 52 and the pair of first conductive members 33b can be reliably electrically connected without visual observation. there is

Here, as shown in FIG. 2, the electrical connection portion CT (broken line portion in the drawing) between the first conductive member 33b and the female terminal 52 overlaps the substrate 33 inside the housing 32. . Specifically, when the mounting surface SF of the substrate 33 on which the light source 33a is mounted is viewed from the front (above in FIG. overlapping. As a result, it is possible to reduce the size of the winker lamp 10, and the degree of freedom in designing the winker lamp 10 can be increased by the amount of the size reduction.

Next, in order to prevent the grommet 51 from coming off, the support plate 34 is brought into contact with the grommet 51 (flange portion 51b) as indicated by the arrow M5. At this time, the pair of wires 53 are passed through the notch 34 a of the support plate 34 . After that, as indicated by an arrow M6, the second fixing screw S2 is passed through the screw hole 34b of the support plate 34, and the second fixing screw S2 is screwed to the first fixing column 32g.

Thereby, as shown in FIG. 2, the support plate 34 is fixed to the first fixing column 32g, and the flange portion 51b is supported (pressed) by the support plate 34. Therefore, the grommet 51 is reliably prevented from slipping out of the communication hole 32f. Thus, the work of assembling the lamp portion 30 and the wire harness 50 is completed.

After that, as indicated by an arrow M7, the work of attaching the elastic member 70 to the ramp portion 30 is performed. At this time, the wire harness 50 is passed through the elastic member 70 from the connector connection portion 54 side. Then, while pulling the connector connection portion 54 of the wire harness 50 with a weak force, one longitudinal direction side of the elastic member 70 (left side in FIG. 3) is attached to the other longitudinal direction side (right side in FIG. 3) of the lamp portion 30 (housing 32). ).

Next, in order to fix the elastic member 70 to the ramp portion 30, the fixing plate PL is put inside the elastic member 70 as indicated by the arrow M8. At this time, the pair of wires 53 are passed through the cutout groove G of the fixing plate PL. After that, as indicated by an arrow M9, the third fixing screw S3 is passed through the insertion hole H of the fixing plate PL, and the third fixing screw S3 is screwed to the second fixing column 32h.

As a result, the assembly of the turn signal lamp 10 is finally completed.

As described in detail above, according to Embodiment 1, the first conductive member 33b on the board 33 side and the female terminal 52 on the vehicle-mounted controller CU side are electrically connected to each other inside the housing 32. When the cylindrical elastic member 70 is attached to the housing 32, even if an obstacle comes into contact with the housing 32 and the elastic member 70 is greatly bent, the electrical connection between the first conductive member 33b and the female terminal 52 will not occur. Disconnection can be suppressed.

Further, according to Embodiment 1, when the mounting surface SF of the substrate 33 on which the light source 33a is mounted is viewed from the front, the connection portion between the first conductive member 33b and the female terminal 52 overlaps the substrate 33. there is As a result, the size of the winker lamp 10 can be reduced, and the design flexibility of the winker lamp 10 can be increased to the extent that the size reduction is possible.

Furthermore, according to Embodiment 1, the housing 32 is provided with the support plate 34 that prevents the female terminal 52 from coming off from the communication hole 32f. Accordingly, even if the wire harness 50 assembled from the outside of the housing 32 is temporarily pulled, the wire harness 50 is effectively prevented from coming off the housing 32 . In this case, even if the lamp portion 30 or the wire harness 50 is damaged after the turn signal lamp 10 is assembled, the damage can be easily removed by removing the support plate 34 and pulling out the wire harness 50. (improved maintainability).

Further, according to Embodiment 1, the grommet 51 is provided between the female terminal 52 and the wiring 53 and the housing 32 to seal the space between the female terminal 52 and the wiring 53 and the housing 32. Intrusion of rainwater, dust, etc. into the lamp portion 30 can be reliably prevented.

Next, Embodiment 2 of the present invention will be described in detail using the drawings. It should be noted that portions having functions similar to those of the first embodiment described above are denoted by the same symbols, and detailed description thereof will be omitted.

FIG. 8 shows a cross-sectional view of the winker lamp of Embodiment 2, FIG. 9 shows a view of the housing in FIG. 8 as seen from arrow D, and FIG.

As shown in FIGS. 8 to 10, the winker lamp (lighting device) 80 of the second embodiment has a shape of the second wall W2 of the housing 32 and a length of the wire harness 50 different from that of the first embodiment. Only the shape of one direction side (female terminal 52 side) is different.

Specifically, as shown in FIG. 9, a pair of communication holes 81 are provided between the first fixed column 32g and the second fixed column 32h of the second wall W2. A pair of wires 53 are individually inserted through these communication holes 81 . 8 and 10, only one of the pair of wirings 53 is shown.

A pair of rubber plugs 82 are provided on one side in the longitudinal direction of the wire harness 50 so as to correspond to each wire 53 . These rubber plugs 82 are formed in a substantially cylindrical shape and seal the inside and outside of the housing 32 . An end of the female terminal 52 is fixed inside the rubber plug 82 on one side in the longitudinal direction. Also, one longitudinal side of the wiring 53 is fixed inside the rubber plug 82 on the other longitudinal side.

Thus, in the second embodiment, a pair of rubber plugs 82 are provided instead of the grommet 51 (see FIG. 6) of the first embodiment. That is, these rubber plugs 82 are provided between the pair of female terminals 52 and the pair of wires 53 and the housing 32 (the pair of communication holes 81). It seals between the housing 32 (the pair of communication holes 81). A pair of rubber plugs 82 correspond to the sealing member in the present invention.

To assemble the winker lamp 80, as indicated by an arrow M10 in FIG. 10, each rubber plug 82 (only one of which is shown) is pressed from the outside of the housing 32 into the pair of communicating holes 81 with a predetermined pressure. and insert it. As a result, the pair of female terminals 52 are electrically connected to the distal ends of the pair of first conductive members 33b (corresponding to male terminals) inside the housing 32, respectively, as in the first embodiment. As shown in FIG. 8, the pair of rubber plugs 82 are also retained by the support plate 34 in the same manner as the grommet 51 (see FIG. 2) of the first embodiment.

In the second embodiment formed as described above, substantially the same effects as in the first embodiment can be obtained. In addition, in the second embodiment, when assembling the turn signal lamp 80, the pair of rubber plugs 82 provided corresponding to the pair of wires 53 are individually inserted into the pair of communication holes 81. As compared with the first embodiment, it is possible to individually connect the female terminal 52 and the first conductive member 33b with high accuracy, and the insertion load can be reduced. Therefore, it is possible to prevent a large load from being applied to the connection portion CT between the female terminal 52 and the first conductive member 33b.

Next, Embodiment 3 of the present invention will be described in detail using the drawings. It should be noted that portions having functions similar to those of the first embodiment described above are denoted by the same symbols, and detailed description thereof will be omitted.

FIG. 11 shows a cross-sectional view of the winker lamp of Embodiment 3. FIG. 11, only one wiring 53 of the pair of wirings 53 is shown as a cross section.

As shown in FIG. As a result, the female terminal 52 is electrically connected to the pair of first conductive members 33 b , and the connector 121 with locking mechanism is prevented from coming off from the housing 32 . In this case, since the lock claw 127 is provided on the housing 32, which is a component larger than the connector main body 124, the lock claw 127 can be made larger, and the strength of the lock claw 127 can be increased. Therefore, the strength of the wire harness 50 with respect to the housing 32 can be further enhanced.

Furthermore, it may be as shown in FIGS. 17(a) and 17(b). Specifically, in the modification shown in FIG. 17A, a pair of female terminals 52 are provided with lock claws 129, respectively.

Then, by inserting the rubber plug 82 into the communication hole 81 as indicated by an arrow M19, the lock claw 129 is hooked on the guide tube 102 (second wall W2) inside the housing 32 . As a result, the female terminal 52 is electrically connected to the pair of first conductive members 33b and prevented from coming off by the locking claws 129. As shown in FIG. In this case as well, the engagement projection 123 (see FIG. 15) of the second wall W2 can be omitted, and the shape of the housing 32 can be simplified.

A pair of rubber plugs 82 are respectively inserted into a pair of communication holes 81 provided in the second wall W2, as in FIG. 17(a). Furthermore, the pair of female terminals 52 are guided by the guide tube 102 as in FIG. 17(a). Then, by inserting the rubber plug 82 into the communication hole 81 as indicated by an arrow M20, the lock claw 130 is hooked on the engagement recess 131 inside the housing 32 . As a result, the female terminal 52 is electrically connected to the pair of first conductive members 33b and is prevented from coming off by the lock claw 130. As shown in FIG. In this case, since the locking claw 130 is provided on the housing 32, which is a component larger than the female terminal 52, the locking claw 130 can be made larger, and the strength of the locking claw 130 can be increased. Therefore, the strength of the wire harness 50 with respect to the housing 32 can be further enhanced.
