The main body 2 of the lighting device 1e holds a light guide body 5 that guides light from a light source (not shown) and a light guide body 5, and diffuses light emitted from the light guide body 5 into the vehicle interior. A member 6 is provided. The diffusion member 6 includes a lens portion 61 having an L-shaped cross section and a back wall 62 that supports the light guide body 5 from the back surface and forms a structure for assembling with other members, and includes the lens portion 61 and the back. The wall 62 is integrated via a cross-linking portion provided at a predetermined position in the longitudinal direction. The lens unit 61 has a light receiving unit 61a facing the emission surface 54 of the light guide body 5 and a light emitting unit 61b that emits light emitted from the light guide body 51 to the outside. The light emitting portion 61b of the lens portion 61 is inserted directly below the upper decorative member 1f, and its end surface (light emitting surface 61c) is exposed to the indoor side.

Under the lighting device 1e, an ornament member 1c having a lower decorative member 1d (for example, a metal molding) on the surface is assembled. Further, a door trim upper member 1g is assembled to this, and the door trim upper member is fastened by a fastening member 15 or the like. It is preferable that the light emitting surface 61c of the lens portion 61 of the diffusion member 6 is arranged substantially flush with the surface of the upper decorative member 1f. As a result, the colors of the upper decorative member 1f and the diffusion member 6 are assimilated when the light is turned off, and it is possible to prevent the lens portion 61 from being conspicuous.

FIG. 3 is a perspective view showing a portion of the lighting device 1e in the vicinity of the light source. The back wall 62 (outside the vehicle interior) of the diffusion member 6 that holds the light guide body 5 is provided with an opening 62d or the like for combining with other members. A predetermined optical pattern (not shown) is provided on the back surface (reflection surface) 52 of the light guide body 5 in order to improve the efficiency of reflection. A light source 4 such as an LED substrate (not shown) is attached to the base end of the light guide body 5. The light source 4 is housed in a lamp case 7 attached to the base end of the diffusion member 6. Although the internal configuration of the lamp case 7 is not shown, the inner wall of the lamp case 7 is provided with a convex portion that engages with a convex portion formed on the side surface near the base end of the light guide body 5, and the end surface of the light guide body 5 is provided. Is fixed so as to face the LED. A harness 8 is connected to the light source 4, and a connector 9 for connecting to a power supply terminal (not shown) is provided at the other end of the harness 8.

In the present embodiment, the outer shell 9a of the connector 9 is provided with an elastic engaging portion 90 for locking the connector 9. The diffusion member 6 has a flange 63 extending from the back wall 62, and the flange 63 is provided with a substantially trapezoidal mounting groove 63a whose groove width gradually decreases toward the opening. The mounting groove 63a is opened by cutting out a part (short side) of the flange 63 constituting the outer circumference thereof. A recess 63b that is further recessed into the flange 63 is configured on the inner peripheral edge of the mounting groove 63a.

In the present embodiment, a plurality of harness fixing claws 62f bent and formed in an L-shaped cross section are further formed on the back wall 62 of the diffusion member 6 at intervals. In the present embodiment, two fixed claws 62f having the same upward orientation of the insertion holes are arranged at intervals in the longitudinal direction, and the fixed claws 62f having the opposite (downward) orientation of the insertion openings are arranged between them. They are arranged at different positions (upper part) in the direction perpendicular to the longitudinal direction (vertical direction). At the position covered by the fixed claw 62f, the diffusion member 6 may be provided with an opening in order to facilitate the passage of the harness 8.

FIG. 4 is a perspective view showing the outer shell 9a of the connector 9. The outer shell 9a of the connector is at least partially flexible and elastic, and is formed with a locking structure (engagement portion 90) formed of a member capable of elastic deformation and elastic restoration. .. For the sake of explanation, the portion where the engaging portion 90 is formed is referred to as the lower portion of the outer shell 9a main body. The rib 90a protrudes downward from the bottom surface of the outer shell 9a, and a pair of leg portions 90b inclined so as to be separated upward are formed from the lower end of the rib 90a. The leg portion 90b is bent inward near the upper end (in a direction in which the angle formed by the leg portions 90b and 90b becomes smaller), and the claw portion 90c is formed so that each leg portion 90b is thinned (thickened). Is formed. Therefore, the claw portion 90c protrudes toward the outside of the leg portion 90c (in a direction away from each other). The engaging portion 90 comes into contact with the lighting device main body 2 (flange 63 in this embodiment) at the claw portion 90c and the thinned tip portion 90d ahead of the claw portion 90c. The base end portion of the rib 90a is provided with a pair of blade-shaped portions 90e and 90e that extend laterally toward the bottom. In the longitudinal direction of the connector outer shell 90a, the rib 90a may extend to a portion where the leg portion 90b and the blade-shaped portion 90e do not exist to form a portion consisting only of the rib, and the extended rib (locking rib) may be formed. The width of 90f may be narrower than the rib (supporting rib) 90a of the portion that supports the leg portion 90b.

5A and 5B are cross-sectional views for explaining the locking mechanism of the connector 9 using the engaging portion 90. When mounting the connector, an engaging portion 90 having a substantially arrow-shaped cross section is formed on the illuminating device main body 2 (flange 63 in this embodiment) from the tip of the arrow (as shown by the downward arrow in FIG. 5A). When pushed toward the rectangular slit-shaped mounting groove 63a, the leg 90b is bent inward and inserted, and as shown in FIG. 5B, the peripheral wall of the mounting groove 63a is reduced to the claw portion 90c and the tip of the leg is reduced. The outer surface of the portion 90d is held from the inside of the groove 63a. Further, the blade-shaped portion 90e bends in a form of being pushed upward, and the peripheral edge portion of the mounting groove 62a is sandwiched between the blade-shaped portion 90e and the claw portion 90c. By these two holding forms, the connector is steadily locked. Here, assuming that the distance between the end portion of the blade-shaped portion 90e before mounting and the base portion of the claw portion 90c in the connector insertion direction (vertical direction in the figure) is D, the plate thickness T of the flange 63 is larger than D. However, it is preferable that the size is slightly larger.

FIG. 6 is a view of the flange 63 as viewed from the back surface, and also shows an elastically deformed cross section of the engaging portion 90 of the mounted connector 9. The width W1 at the tip of the leg 90b before mounting is deformed to match the width W2 of the mounting groove 63a. The locking rib 90f is inserted into the recess 63b and serves as a detent for the connector 9. When removing the connector 9 from the temporary fixing position, the connector 9 may be pulled out along the long side of the mounting groove 63a in the direction of the arrow in FIG. 6 (the direction indicated by the broken line arrow in FIG. 3). At that time, the force required for extraction can be adjusted by adjusting the width W2. W2 of the mounting groove 63a may be constant, but as shown in the figure, it may be configured to gradually decrease toward the opening. As a result, the force required for extraction increases as the connector approaches the opening. Therefore, for example, even if an external force is applied to cause the connector to shift in position, the elastic restoring force of the engaging portion causes the connector 9 to return to its original position. Return to the installation position. Therefore, in combination with the function of preventing the connector 9 from coming off and the function of preventing rotation by the locking rib 90f and the recess 63b, the connector 9 can be accurately held at a predetermined position and the misalignment can be suppressed.

The locking mechanism of the connector 9 described with reference to FIGS. 5A and 5A and FIG. 6 can be used when the mounting groove 63a is provided at the position for temporary fixing and the connector 9 is temporarily fixed detachably. .. It is also used when a groove having the same or similar structure as the mounting groove 63a is provided at the connection position between the connector 9 and the power supply terminal (not shown) to fix the connector 9 at a predetermined connection position. Can be done.

As described above, a plurality of fixed claws 62f having an L-shaped cross section for hooking the harness 8 are formed in the vicinity of the groove 63a shown in FIG. By installing the connector 9 in the mounting groove 63a of the flange 63 and fixing the harness 8 over the fixing claw 62f, the harness 8 does not partially swing away from the main body of the lighting device 1e, so that the lighting device 3 can be used. The harness 8 does not get in the way when incorporated as a part of the interior member 1, and workability is improved.

7 and 8 are views showing a state in which the lighting device 3 described above is installed in the interior trim 1. FIG. 7 shows the connector 9 in a temporarily fixed state, and FIG. 8 shows a power supply terminal (power supply terminal). It is connected to 10. Although not shown, since the shade is arranged on the lighting device 3, if the connector 9 is fixed near the lighting device 3, it becomes difficult to connect the terminal 10 from the power supply side to the connector 9, and it cannot be visually recognized. , There is also the problem that the connection cannot be confirmed. Therefore, the connector 9 needs to be fixed at a place away from the lighting device 3. In this embodiment, the power supply terminal 10 is arranged at the portion of the middle member 1b. Similar to the flange 63 of the main body of the lighting device, a fixing member 11 for mounting the connector 9 is provided in the vicinity of the power supply terminal 10, and a fixing groove (second mounting groove) 11a is formed therein. Since the fixing groove 11a cannot be removed once the connector is attached at one end, the fixing groove 11a may be closed without opening. After incorporating the lighting device 3 into the interior member 1 as shown in FIG. 7, the connector 9 and the harness 8 are removed from the temporary holding position on the flange and installed in the fixing groove 11a (see FIG. 7) as shown in FIG. It can be connected to the power supply terminal 10. As a result, it is possible to eliminate complicated work such as when the harness 8 is fixed with tape, and it is also possible to prevent the harness 8 from being entangled during assembly.

The material of each part of the lighting device is not particularly limited as long as it can transmit and diffuse light, but for example, polycarbonate can be preferably used, and for example, it can be formed by injection molding. A material that diffuses light, such as silicone resin particles, may be dispersed in the diffusing member 6, particularly the lens portion 61. The outer shell 9a of the connector 9 provided with the elastic engaging portion 9b can also be formed by, for example, injection molding using a resin such as polycarbonate. The material of the light guide is not particularly limited, but may be an acrylic resin, for example, PMMA. The optical pattern formed on the reflective surface of the light guide may be one in which a plurality of grooves in directions orthogonal to the extension direction are arranged at a predetermined pitch, but recesses having a predetermined shape, for example, a hemisphere, a cone, a truncated cone, or a pyramid. , Pyramid cones and the like may be provided at predetermined intervals along the extension direction of the light guide.

As described above, according to the present invention, since it is not necessary to use a tape for holding a connector or a harness in a lighting device incorporated in an interior member, the process of assembling the interior member is simplified, and the work environment and work efficiency are improved. As well as improving, the amount of waste can be reduced.

As described above, the preferred embodiment has been described with reference to the drawings, but various additions, changes, and deletions can be made without departing from the spirit of the present invention. For example, in the above description, the interior trim of the rear door of an automobile has been described as an interior member according to the present invention, but the interior member may be, for example, an interior trim of a front door, and a roof lining, an instrument panel, and a scuff plate. It may be another member such as. Further, it may be a partial member constituting a part of these members, and may be, for example, a decorative member in which a lighting device and a decorative panel are combined. Therefore, such things are also included within the scope of the present invention.
