It is a perspective view for demonstrating the attachment method to an attachment board.

  As shown in FIGS. 1 to 5, the indoor lighting device 1 includes a device main body 2 and a cover member having an electric wire cover 3, an electronic component cover 4, and a lighting cover 5, each of which is a divided cover. The apparatus body 2 includes an electric wire connecting portion 7 provided with a bus bar (not shown) to which the electric wires 6 are connected, an electronic component connecting portion 8 to which a rectifier diode (not shown) and a current limiting resistor (not shown) are connected, and It has the illumination connection part 10 to which LED9 for room lighting is connected.

  The wire connection portion 7 has a pair of locking portions 7a and 7b provided on both side surfaces (the locking portions 7a and 7b provided on one side surface are not shown). The electric wire 6 is electrically connected to a bus bar (not shown), and then the electric wire cover 3 is attached in the direction of arrow A in FIG. By this attachment, the pair of engaging grooves 3 a and 3 b provided on both side surfaces of the wire cover 3 are engaged with the locking portions 7 a and 7 b of the wire connection portion 7, and the wire cover 3 protects the wire connection portion 7. Will do.

  The electronic component connecting portion 8 has a pair of engaging portions 8a and 8b on both side surfaces (the engaging portions 8a and 8b provided on one side surface are not shown). A rectifier diode (not shown) and a current limiting resistor (not shown) are connected to the portion 8, and then the electronic component cover 4 is mounted in the direction of arrow B in FIG. By this mounting, the pair of engaging grooves 4a and 4b provided on both side surfaces of the electronic component cover 4 are engaged with the locking portions 8a and 8b of the electronic component connecting portion 8, and the electronic component cover 4 is connected to the electronic component. The part 8 will be protected.

  Further, the lighting connection portion 10 is provided with a pair of locking portions 10a on both side surfaces (the locking portion 10a provided on one side surface is not shown). The LED 9 is connected in the direction shown (that is, the direction orthogonal to the longitudinal direction of the room lighting device 1), and then the lighting component cover 5 is mounted in the direction of arrow C in FIG. With this mounting, the pair of engaging grooves 5 a provided on both side surfaces of the lighting cover 10 are engaged with the locking portions 10 a of the lighting connection portion 10. Further, at this time, the insertion connecting portions 10b and 5b provided in the illumination connecting portion 10 and the illumination cover 5 are inserted into the insertion holes 11a of the mounting plate 11 shown in FIG. 2 and 4). Thereby, the illumination cover 5 protects the illumination connection part 10.

  Here, the structure and the like of the illumination cover 5 will be described in detail.

  The illumination cover 5 is formed of a transparent material such as PC (that is, polycarbonate) or acrylic so that the inside of the illumination connection portion 10 can be seen from the outside. Moreover, when the illumination cover 5 is attached to the illumination connection portion 10 as described above, the illumination connection portion 10 includes the division insertion portion 5b that fits into the division insertion portion 10b provided in the illumination connection portion 10, and this division insertion portion. The front end surface 5c of 5b is processed such as lens cutting or embossing. Therefore, the light from the LED 9 housed in the divided insertion portion 5b is condensed or diffused at the tip surface 5c. That is, the front end surface 5c that emits light acts as a light distribution portion. Therefore, it is not necessary to provide a dedicated lens member as the light distribution lens of the LED 9, which is advantageous in terms of cost and miniaturization.

  Further, the illumination cover 5 is configured such that the direction in which it is attached to the apparatus main body 2 (that is, the illumination connection portion 10) (that is, the direction of the arrow C) is different from the other electric wire cover 3 and the electronic component cover 4. . This is due to the following reason. If the illumination cover 5 is also configured to be mounted on the apparatus main body 2 in the same direction as the wire cover 3 or the electronic component cover 4, the LED 9 is disposed in a direction orthogonal to the direction shown in FIG. As a result, for example, at the end portion of the apparatus main body 2 (that is, the right end portion in FIG. 1), it corresponds to the divided insertion portion. The projecting cylindrical shape portion is provided, and the indoor lighting device is longer in the longitudinal direction than the indoor lighting device of the present embodiment shown in FIG. Therefore, the room lighting device must be arranged in the longitudinal direction along the direction of arrow D in FIG. 5 to be described later and attached to the mounting plate, which impairs the space saving of a vehicle such as an automobile. Furthermore, in the state where the indoor lighting device is completely attached to the mounting plate provided in the vehicle, the indoor lighting device is longer in the longitudinal direction as described above, so the tubular portion protrudes from the design portion, Problems such as impairing the interior design will also occur. In view of such points, in the present embodiment, the mounting direction of the indoor lighting device 1 is changed by making the mounting direction of the lighting cover 5 to the apparatus main body 2 different from the mounting direction of the other divided covers as described above. Space is saved by preventing the dimensions from becoming longer.

  As described above, each divided cover (that is, the wire cover 3, the electronic component cover 4, and the lighting cover 5) is provided for each of the connection portions (that is, the wire connection portion 7, the electronic component connection portion 8, and the illumination connection portion 10). When the interior lighting device 1 is assembled as shown in FIG. 2, the interior lighting device 1 is attached to the mounting plate 11 provided in the vehicle. 5 will be described.

  As shown in FIG. 5, the mounting plate 11 has an insertion hole 11 a, and the shape of the insertion hole 11 a is such that the divided insertion portions 10 b and 5 b provided in the illumination connection portion 10 and the illumination cover 5 respectively. It is substantially the same as the outer shape of the inserted insertion portion 12 (preferably slightly larger so that it can be inserted).

  First, the insertion portion 12 is inserted into the insertion hole 11a of the mounting plate 11 in the direction of arrow D. When the cutout groove 5e formed at the lower end of the protruding portion 5d of the insertion portion 12 reaches a position where it can be fitted into the mounting plate 11, the insertion is stopped. In this embodiment, the state where the insertion portion 12 is inserted to a position where the insertion portion 12 can be inserted in the direction of the arrow D is configured so that the cutout groove 5e can be fitted into the mounting plate 11. There is no need to worry about. Further, the height of the cutout groove 5 e is slightly larger than the thickness of the mounting plate 11.

  Next, when the room lighting device 1 is twisted (ie, rotated), for example, by 90 degrees in the direction of arrow E around the central axis 13 of the insertion portion 12, the room lighting is performed with the mounting plate 11 fitted in the notch groove 5e. The device 1 rotates 90 degrees counterclockwise with respect to the mounting plate 11. Thus, the portion of the protruding portion 5d having an outer diameter larger than the diameter of the insertion hole 11a is placed on the portion of the mounting plate 11 that forms the insertion hole 11a, so that the protruding portion 5d is attached to the mounting plate. 11, the interior lighting device 1 is locked to the mounting plate 11. Thus, the attachment of the room lighting device 1 to the attachment plate 11 is completed.

  When the installation of the interior lighting device 1 is completed as described above, when the design portion 14 of the vehicle is arranged on the mounting plate 11 with a height dimension substantially the same as the height dimension of the insertion portion 12, The distal end surface of the insertion portion 12 is positioned at the portion indicated by 14a of the design portion 14, and the insertion portion 12 does not protrude from the design portion 14 to impair the design of the room. Further, the dimension of the indoor lighting device 1 in the direction of arrow D is (the height dimension of the lighting cover 5) + (the height dimension of the insertion portion 5b), and the mounting direction of the lighting cover to the apparatus main body is also as described above. Compared with the interior lighting device ((longitudinal dimension of the apparatus main body 2) + (height dimension of the cylindrical part corresponding to the insertion part)) in the direction of arrow D when it is the same as other divided covers The dimension in the direction is less than half, and space can be saved.

  Finally, the effects of the above embodiment will be described together below.

  Since the cover member that protects the apparatus main body 2 is divided into a plurality of divided covers such as the electric wire cover 3, the electronic component cover 4, and the lighting cover 5, the divided portions other than the electric wire cover 3 even when force is applied to the electric wires 6. No force is applied to the cover, the electronic component cover 4 and the lighting cover 5 are not opened, and there is no possibility of damaging the rectifier diode, the LED 9 or the like. Needless to say, this effect can be obtained if the cover member for protecting the apparatus main body 2 is divided into at least an electric wire cover and another cover. Further, in the case of such a configuration, a strain relief structure other than the electric wire cover 3 is not required, which contributes to downsizing of the indoor lighting device 1.

  Further, even if the electronic component cover 4 or the illumination cover 5 is opened for maintenance such as replacement of a rectifier diode, a current limiting resistor, or a light emitting diode, other divided covers are not opened as described above. Therefore, it is possible to prevent, for example, damage to the electric wire 6 or the like connected to another connection portion.

  Further, since the mounting direction of the lighting cover 5 to the lighting connection portion 10 is different from that of the other divided covers, the LED 9 can be arranged in the direction as shown in FIG. The dimension in the direction of attachment to the plate 11 can be shortened, and space saving can be achieved.

  Moreover, since the illumination cover 5 is formed of a transparent material, it is not necessary to provide a dedicated lens, and the indoor illumination device 1 can be reduced in size and space. Similarly, the front end surface 5c of the illumination cover 5 is processed such as lens cutting or embossing so as to act as a light distribution unit for condensing or diffusing the light from the LED 9, so that a dedicated light distribution lens is provided. Therefore, it is possible to achieve downsizing and space saving of the indoor lighting device 1.

  Further, the insertion portion 12 formed by fitting the divided insertion portions 10b and 5b provided in the illumination connection portion 10 and the illumination cover 5 respectively has a hole shape substantially the same as the outer shape of the insertion portion 12. Since it is inserted into the insertion hole 11a of the plate 11, the insertion portion 12 is inserted into the insertion hole 11a of the mounting plate 11 when the illumination cover 5 is not completely attached to the illumination connection portion 10, for example, in the case of half-fitting. It is possible to know that the fitting of the lighting connection portion 10 and the lighting cover 5 is not appropriate at the time of installation work, and it is possible to prevent the occurrence of defective products.

  Furthermore, in a state where the insertion portion 12 is inserted into the insertion hole 11a of the mounting plate 11, the room lighting device 1 is formed at the lower end of the protruding portion 5d by twisting a predetermined amount around the insertion portion 12 with respect to the mounting plate 11. Since the mounting plate 1 is fitted in the notch groove 5e, after the indoor lighting device 1 is mounted on the mounting plate 11, the indoor lighting device 1 from the mounting plate 11 is used unless the indoor lighting device 1 is removed from the mounting plate 11. Will not fall out. That is, while the structure for holding the room lighting device 1 on the mounting plate 11 is simple, the mounting state of the room lighting device 1 on the mounting plate 11 can be strengthened.

  The present invention is not limited to the above-described embodiments, and modifications, improvements, etc. can be made as appropriate. In addition, the shape, size, numerical value, form, 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.
