Description

  The present invention relates to indoor lighting.

  A vehicle is usually provided with a sun visor for blocking backlight. In such a sun visor, a small mirror may be provided separately from the rearview mirror.

  When the sun visor is provided with a mirror as described above, an indoor illumination lamp may be provided near the windshield of the ceiling so that the mirror can be used even at night. This room illumination lamp is provided separately from the dome lamp provided in the approximate center of the ceiling.

  Further, the interior lighting is provided at a position hidden by the sun visor when the sun visor is folded to the ceiling side. Since this room illumination lamp is used only when a mirror is used, it is much smaller than a dome mirror.

  Further, the sun visor mirror may be provided with a cover that opens and closes by sliding. In some cases, the interior lighting is turned on when the cover is opened.

  FIG. 12 is a cross-sectional view of a conventional room illumination lamp 1. This room lamp 1 has a design part 11 and a functional part 12 that is detachably attached to the design part 11. Among these, the design part 11 has a frame-shaped housing 13, a lens 15 provided in the housing 13, and clips 16 provided on both sides of the housing 13.

  As shown in FIG. 13, the functional unit 12 of the room lamp 1 has a concave portion 24 formed in the functional unit main body 18, and a press contact blade 25 is provided in the concave portion 24. A V-shaped groove 25 a is formed at the tip of the press contact blade 25. The press contact blade 25 is connected to the valve 17. The recess 24 is provided with a lid 26 that can be freely opened and closed.

  When connecting the flat electric wire 22 to the function part 12, as shown in FIG. 14, the flat electric wire 22 is inserted into the recess 24, and the flat electric wire is inserted into the V-shaped groove 25a provided at the tip of the press contact blade 25. 22 is placed. When the lid portion 26 is closed, the flat electric wire 22 is pressed toward the press contact blade 25, the insulating film of the flat electric wire 22 is broken by the press contact blade 25, and the core wire is electrically connected to the press contact blade 25. Thereby, the flat electric wire 22 and the valve 17 are connected via the press contact blade 25.

  Here, a protrusion 26 a that presses the flat electric wire 22 is formed on the surface of the lid portion 26 on the pressure contact blade 25 side. Between the protrusions 26a and 26a, it is formed substantially flat. By this protrusion 26a, the flat electric wire 22 is reliably pushed into the groove 25a.

  Next, a method for attaching the above-described room illumination lamp 1 to the ceiling trim 19 of the vehicle will be described. As shown in FIG. 15, a dome lamp mounting hole 30 and an indoor lighting lamp mounting hole 31 are provided in the ceiling trim 19 to which the indoor lighting lamp 1 is to be mounted.

  First, as shown in FIG. 16, only the design portion 11 of the room illumination lamp 1 is attached to the room illumination lamp mounting hole 31 of the ceiling trim 19. Next, as shown in FIG. 17, the functional unit 12 is attached to the design unit 11 from the back surface 19 a side of the ceiling trim 19. A flat electric wire 22 is connected to the functional unit 12 in advance. Next, as shown in FIG. 18, the ceiling trim 19 is attached to the ceiling 32 a of the vehicle main body 32.

  When replacing the bulb 17 of the room lamp 1, the entire room lamp 1 is removed from the ceiling trim 19 as shown in FIG. At this time, in order to avoid a tensile force from acting on the flat electric wire 22, the flat electric wire 22 is provided with an extra length portion 22a.

  As shown in FIG. 20, the extra length portion 22 a of the flat electric wire 22 is held by a clip 33 provided in the functional portion 12. The clip 33 is formed in a substantially L shape as shown in FIG. Then, the flat electric wire 22 is inserted and held in the gap between the clip 33 and the functional unit main body 18.

The inner width b1 of the clip 33 is formed substantially the same as the insertion width b2 of the flat wire 22. Further, locking claws 34, 34 facing each other are formed on the inner surface of the clip 33. An insertion path 35 for inserting the flat electric wire 22 into the clip 33 is formed between the locking claws 34.

  However, as shown in FIG. 22, the conventional interior illumination lamp 1 has a flat back surface 26b of the lid portion 26 of the functional portion 12, and therefore, the entire functional portion 12 is disassembled from the ceiling trim 19 when replacing the bulb, for example. When doing so, there is a possibility that the force toward the lid portion 26 directly acts on the flat electric wire 22 and the lid portion 26 comes off from the recess 24.

If the cover part 26 comes off from the recessed part 24, the problem that the flat electric wire 22 will drop | omit from the press-contacting blade 25 and it will break will generate | occur | produce.
In FIG. 22, reference numeral 27 denotes a locking groove provided in the concave portion 24, and 28 denotes a locking claw provided at both end portions of the lid portion 26 and locked to the locking groove 24.

  It is an object of the present invention to provide an interior lighting that can prevent a drop of an electric wire press-connected to the functional unit without increasing the size of the functional unit.

  In order to achieve the above-described object, the present invention provides a design portion in which a lens is fixed to a housing that can be attached to an opening provided in an interior material of a vehicle, and the interior material by being supported by the design portion. A pressure part disposed on the back surface side and having a light source, the pressure part being press-contacted to an electric wire for supplying electric power to the light source, and the pressure contact of the electric wire against the pressure contact blade An interior illumination lamp including a lid portion for maintaining a state, wherein an end portion along a longitudinal direction of the electric wire on a back surface of the lid portion is inclined with respect to a common radial direction of each core wire in the electric wire. It has an inclined surface.

Here, the electric wire includes a flat electric wire in which core wires are arranged in parallel, a plurality of independent electric wires, and the like.
In this invention, if the force to the cover part side acts on an electric wire, an electric wire will move to the side edge part side of a cover part along the inclined surface provided in the back surface of the cover part. As a result, the locking claws provided at both end portions of the lid portion are urged outward by the electric wires, that is, in a direction to be locked in the locking grooves formed in the concave portion of the lid portion, and The stopping power increases.

Here, the end portion along the longitudinal direction of the electric wire on the back surface of the lid portion can be formed as the inclined surface so as to be tapered toward the electric wire.
In this case, the plurality of electric wires of the electric wire are divided into two along the inclined surface, and these electric wires move along the inclined surface to both end portions of the lid portion. As a result, the locking claws provided on both sides of the lid are urged toward the locking groove, and the locking force on the locking groove is increased.

  According to the present invention, since only the inclined surface is formed on the back surface of the lid portion, the size can be reduced. Moreover, even if the force of a common radial direction acts on an electric wire, it can prevent that the cover part of a function part remove | deviates, and, thereby, can prevent that an electric wire remove | deviates from a press-contact blade and is cut | disconnected.
