On the other hand, when removing the LED module 30 from the LED module connector, first, after the three small screws Bs in the locking member 14 are loosened, the locking member 14 is moved from the position indicated by the solid line in FIG. It can be moved to the position indicated by the chain line.
As a result, the cover member 12 is unlocked with respect to the base member 10, so that the cover member 12 is slightly separated from the base member 10 by the pushing-up force due to the restoring force of the movable contact portion 18 b of the connection terminal 18. It is rotated. Therefore, the LED module 30 can be easily detached from the LED module connector by grasping and pulling out one end of the LED module 30.

  Furthermore, when assembling the LED module connector to, for example, the heat sink HS disposed in the lighting device, first, the base member 10 is disposed on the surface of the heat sink HS, and then each small screw Bs is inserted into each hole 10d. And screwed into the female screw hole of the heat sink HS. As a result, the LED module connector is fixed on the surface of the heat sink HS.

  Then, the male connector portion 22 connected to the power supply wiring portion (not shown) is detachably connected to the female connector portion 20 as shown in FIGS. 1 and 6. Therefore, the LED module connector can be electrically connected to the power supply wiring portion without requiring complicated work such as soldering and fixing work.
