DETAILED DESCRIPTION OF THE INVENTION
The connector 2 of this embodiment is used for the connection between the hook ceiling 1 attached to a construction surface such as a ceiling as shown in FIG. 4 and the lighting fixture 3, and as shown in FIGS. As in the conventional configuration shown in FIG. 5, a pair of hooking blades 29 having L-shaped tips projecting from the upper surface of the container body 20 are mechanically and electrically connected to the hooking ceiling 1. Here, the electrical connection between the lighting fixture 3 and the hook ceiling 1 is performed via a connection line 7 (see FIG. 4) provided in the connector 2.
[0013]
Since the configuration of the hook ceiling 1 is the same as the conventional configuration shown in FIG. 5, the same reference numerals are assigned to the same components and the description thereof is omitted.
[0014]
The body 20 of the connector 2 is configured by combining a cylindrical body 21 having an upper surface opened and a disc-shaped cover 22 that closes the opening of the body 21. The hooking blade 29 and one lock claw 24 protrude. Here, the hooking blade 29 protrudes upward at a position sandwiching the center of the cover 22 on one straight line passing through the center of the cover 22 in the peripheral portion of the cover 22. Further, the lock claw 24 protrudes from a position shifted along the circumferential direction of the cover 22 from the protruding position of the one hooking blade 29 on the upper surface of the cover 22, and the body 20 is attached to the body 11 of the hooking ceiling 1. In the attached state, the hook plug blade 29 is inserted into the wide portion 19a of the hook plug blade insertion port 19 into which the hook plug blade 29 is inserted.

The locking claw 24 is released from the pressing force applied by the body 11 during the rotation, and the leading end enters the wide portion 19 a of the hooking blade insertion port 19.
[0017]
By the way, the cover 22 of the connector 2 is provided with a rib 16 for preventing a center shift, which is a recess opening at the center of the upper surface of the cover 22 and projecting from the center of the bottom wall of the hooking ceiling 1. The opening 23 of the recess 23 is formed in a substantially circular shape.
[0018]
Thus, in the connector 2 of the present embodiment, when the device body 20 of the connector 2 is rotated in the direction opposite to the direction of attachment (the direction opposite to the direction of the arrow B in FIG. 1) without pressing the lock release button 25. Even if the movement of the lock claw 24 is restricted by the contact of the lock claw 24 with the inner peripheral edge of the opening of the wide portion 19a in the circumferential direction of the hooking blade insertion port 19, the opening shape of the recess 23 is formed in a substantially circular shape. As a result, the rib 16 is guided along the inner peripheral wall of the recess 23, so that the rib 16 does not run on the peripheral edge of the opening of the recess 23 and the center deviation from the hooking ceiling 1 occurs. Can be prevented more reliably. Further, when the container body 20 is attached to the hooking ceiling 1, the rib 20 is rotated when the container body 20 is rotated after the hooking blade 29 is inserted into the wide portion 19 a of the hooking blade insertion port 19 of the body 11 of the hooking ceiling 1. Since 16 is guided along the inner peripheral wall of the recess 23, the central axis of rotation of the vessel body 20 is stabilized, and the attachment of the vessel body 20 to the hooking ceiling 1 is facilitated. 2, a cylindrical lamp socket 6 is coupled to a lower end portion of a cylindrical portion 21 b that projects continuously and integrally from a body 21, and is attached to a fixture body 30 of a lighting fixture 3 as shown in FIG. 4, for example. The light bulb 7 is connected to the lamp socket 6. Here, a hook-shaped piece 21 a is projected from substantially the entire circumference at the upper end of the outer peripheral surface of the peripheral wall of the body 21 of the connector 2, and the device body 20 is placed on the device body 30 from above the device body 30. It is inserted into a drilled connector insertion hole (not shown), and is fixed to the instrument body 30 in a state where the lower surface of the hook-shaped piece 21a is locked to the upper surface of the instrument body 30. A shade 60 is detachably attached to the instrument body 30. By the way, this lighting fixture 3 is provided with a lighting circuit (not shown) of the light bulb 70 and a human sensor (not shown) for detecting the presence or absence of a person in the detection area. The light bulb 70 is turned off after a predetermined time (for example, 30 seconds) after it is no longer obtained. For this reason, the instrument main body 30 has a bottomed cylindrical shape that houses a printed board (not shown) on which circuit components of the lighting circuit are mounted, a printed board (not shown) on which the human sensor is mounted, and the like. The circuit block housing part 31 is provided continuously and integrally, and the light receiving lens 8 of the human sensor located at the lower part of the circuit block housing part 31 is disposed from the bottom wall of the circuit block housing part 31.
