  Next, a procedure for installing the lighting fixture on the ceiling material 100 will be described.

  At the time of shipment from a factory or the like, the instrument main body 1 is configured such that the main body 131 of the terminal block 13 is attached to the bottom plate 111 of the instrument main body 1 and the pair of engagement protrusions 1324 are inserted into the pair of engagement holes 1114. 132 is temporarily held by the instrument body 1 and packed in a cardboard box or the like. Therefore, the worker first unpacks and takes out the instrument body 1.

  Subsequently, the worker connects the power line 4 exposed from the ceiling material 100 to the indoor side to any one of the power holes 1111 provided in the instrument body 1 (in the example of FIG. 4, the central power hole 1111). Pass through. In addition, the operator lifts the instrument main body 1 upward and passes the two suspension bolts 200 exposed to the indoor side through the ceiling material 100 through the pull-in holes 1112. The worker then fixes the appliance body 1 to the ceiling member 100 by screwing the nut 201 into the suspension bolt 200.

  Next, the operator connects the power line 4 to the terminal block 13. Then, the operator pulls out the pair of engaging protrusions 1324 from the pair of engaging holes 1114 to remove the connector 132 from the instrument main body 1, and connects the removed connector 132 to the connector 243 of the power supply device 24. Finally, the operator attaches the light source unit 2 to the instrument main body 1 by a well-known fitting structure (not shown) provided in the instrument main body 1 and the light source unit 2 respectively. At this time, at least a part of the light source unit 2 (the power supply device 24, the protruding wall portion 232 of the cover member 23, etc.) is accommodated in the accommodating recess 11 of the instrument body 1. The lighting fixture is constructed on the ceiling by the above procedure (see FIG. 5).

  As described above, in the lighting fixture of the present embodiment, the pair of engagement holes 1114 are provided in the bottom plate portion 111 of the fixture main body 1, and the pair of engagement protrusions 1324 are provided in the housing 1321 of the connector 132. . Thereby, the connector 132 can be temporarily held by the instrument main body 1 when the instrument main body 1 is transported or when the instrument main body 1 is attached to the ceiling material 100 or the like. For this reason, the possibility that the connector 132 moves relative to the instrument main body 1 when the instrument main body 1 is transported is low, and the connector 132 and the electric wire 133 are not easily disturbed when the instrument main body 1 is attached.

  Here, as shown in FIG. 2B, the engagement protrusion 1324 protrudes toward the second surface 111 </ b> B side of the bottom plate portion 111 in a state where the connector 132 is temporarily held on the instrument body 1. For this reason, when the engagement protrusion 1324 is pushed from the second surface 111B side by a side surface such as a cardboard box, the engagement protrusion 1324 comes out of the engagement hole 1114, and the connector 132 is detached from the instrument body 1. There is a possibility. On the other hand, in the instrument main body 1 of this embodiment, the engagement hole 1114 is provided in the bottom plate part 111 of the instrument main body 1 at a position adjacent to the power supply hole 1111 provided with the protrusion 141 (bushing 14). Yes. Thereby, the possibility that the engaging protrusion 1324 is unintentionally pushed from the second surface 111B side is reduced, and the possibility that the temporarily held connector 132 is unintentionally detached from the instrument body 1 is reduced. be able to.

  Moreover, in the lighting fixture of this embodiment, a part of bushing 14 attached to the power supply hole 1111 functions as the protrusion part 141 which protrudes to the 2nd surface 111B side. For this reason, for example, a manufacturing process can be reduced compared with the case where the protrusion for exclusive use of the engagement protrusion 1324 is provided at a position adjacent to the engagement hole 1114.

  Further, in the lighting fixture of the present embodiment, the interval between the pair of engaging protrusions 1324 is set larger than the interval between the pair of engaging holes 1114. As a result, the engagement protrusion 1324 is less likely to be detached from the engagement hole 1114, and the connector 132 is less likely to fall out of the instrument body 1.

  In the example of FIG. 1, a bushing 14 (protrusion 141) is provided at the opening edge of the power supply hole 1111, and an engagement hole 1114 is provided at a position adjacent to the power supply hole 1111. However, as in the modification shown in FIG. 6, a bushing 14 (protruding portion 141) is provided at the opening edge of the drawing hole 1112 through which the suspension bolt 200 is passed, and an engagement hole 1114 is provided at a position adjacent to the drawing hole 1112. May be.

  Further, a pair of the drawing hole 1112 and the long hole 1113 (a pair of the front drawing hole 1112 and the long hole 1113) may be used for the pair of engagement holes 1114. That is, the connector main body 1 may be temporarily held by inserting the pair of engaging protrusions 1324 into the drawing hole 1112 and the long hole 1113, respectively. Even in this case, since the bushing 14 (projection 141) is provided at a position adjacent to the set of the drawing hole 1112 and the long hole 1113, the connector 132 is unintentionally detached from the instrument body 1. It is possible to reduce the possibility that In this case, it is not necessary to newly provide the engagement hole 1114 for temporary holding. In this case, the distance between the pair of engaging protrusions 1324 provided on the connector 132 is slightly smaller than the distance between the drawing hole 1112 and the long hole 1113 (the shortest distance between the circular drawing hole 1112 and the long hole 1113). It is preferable that the setting is small.

  Further, the engagement protrusion 1324 and the engagement hole 1114 may be provided one by one. In this case, it is preferable that the diameter of the engaging protrusion 1324 is set slightly larger than the diameter of the engaging hole 1114.

  As described above, the lighting fixture of the present embodiment includes the light source unit 2, the fixture body 1, the terminal block 13, and the connector 132.

The bottom plate part 111 is formed in a long shape. The lead-in hole 1112 and the power supply hole 1111 are provided side by side in the longitudinal direction of the bottom plate portion 111. In the bottom plate portion 111, a long hole 1113 that is long in the longitudinal direction of the bottom plate portion 111 is formed on at least one side in the short direction of the bottom plate portion 111 with respect to the drawing hole 1112. The connector 132 is temporarily held by the instrument main body 1 with the pair of engaging protrusions 1324 being inserted into the drawing holes 1112 and the long holes 1113, respectively.

  According to this configuration, it is not necessary to separately provide the engagement hole 1114 for temporarily holding the engagement protrusion 1324, and the manufacturing process can be simplified.

  Like the lighting fixture of the present embodiment, the connector 132 preferably has a pair of engaging protrusions 1324 as the engaging protrusions 1324. The bottom plate portion 111 has a pair of engagement holes 1114 as the engagement holes 1114. The interval between the pair of engaging protrusions 1324 is larger than the interval between the pair of engaging holes 1114.

  According to this configuration, it is possible to further reduce the possibility that the temporarily held connector 132 is unintentionally detached from the instrument body 1.
