I have. The electric wire 9 connecting the output of the human body sensor unit 1 to the control circuit unit 2 through a hole 8 formed in a metal plate 7 serving as a case of the control circuit unit 2 is connected to the insulating plate located on the inner surface side of the metal plate 7. 4 is formed so as not to touch the edge of the hole 8 formed in the metal plate 7 through the hole 10 formed in a part of the metal plate 7.

More specifically, the human body sensor unit 1 comprises:
An infrared transmitting cover 12 provided on a lower surface side of a synthetic resin case 11 for covering a human body sensor (not shown), a printed circuit board 13 housed in the case 11, and a printed circuit board 13
And a connector 14 fixedly connected to the connector 14. The human body sensor unit 1 is screwed and fixed to the metal plate 7 with screws 15. A portion of the case 11 facing the connector 14 constitutes a rotatable opening / closing lid 17 via a thin hinge 16, and is assembled to the metal plate 7 in a closed state with the opening / closing lid 17 positioned upward. In this state, the upper end of the opening / closing lid 17 enters the hole 8 and is positioned on the inner surface of the metal plate 6 so that the opening / closing lid 17 cannot be opened. The electric wire 9 is a tape electric wire, and its insulating film is extremely thin. One end of the electric wire 9 is connected to the connector 14 with the opening / closing lid 17 opened as shown by the dotted line in FIG. 5, and then the opening / closing lid 17 is closed and the opening / closing lid 17 is engaged with the inner surface of the metal plate 6 as shown in FIG. It is stopped and does not open.

The control circuit section 2 is formed integrally with metal plates 6 and 7 having a substantially L-shaped cross section, an insulating plate 4 located on the inner surface side of the metal plate 6, and an inner surface side of the insulating plate 4. The printed board 5 includes a metal cover 18 attached to the metal plate 6. The printed board 5 and the insulating plate 4 are attached to the metal plate 6 through a plurality of fasteners 19 passed from outside the metal plate 6. The connector 20 is connected and fixed to the printed circuit board 5, and the electric wire 9 is connected to the connector 20. The metal cover 18 is attached to the metal plate 6, and the two side pieces of the metal cover 18 enter the inner surfaces of the two side pieces of the metal plate 6, and the inward small protrusions 21 formed on the both side pieces of the metal plate 6. Are locked in the holes 22 on both side pieces of the metal cover 18. The two side pieces of the elastic insulating plate 4 apply an appropriate pressure to the inner surfaces of the two side pieces of the metal cover 18 so that the metal cover 18 does not easily come off the metal plate 6. The small protrusion 21 in FIG. 2 is a protruding bulging portion, and the small protrusion 21 in FIG. 3 is a cut and raised piece.

The human body sensor section 1 and the control circuit section 2 assembled together are housed in a cylinder 23 made of synthetic resin, and the infrared transmitting cover 12 covering the human body sensor is exposed through a hole in the lower surface of the cylinder 23. A support plate 25 connected to the socket support plate 24 is attached to an upper surface of the control circuit unit 2, that is, an upper end of the metal plate 6, and a socket 26 is attached to a lower surface of the socket support plate 24 via a socket support 24a. The lamp 3 is mounted on the socket 26. A shade holder 27 is screwed onto the outer periphery of the socket 26, and a flange 28 at the upper end of the shade holder 27 supports a shade 28 through which the socket 26 is passed. Sade 28
One side is assembled with the cylinder 23 by appropriate means, and the cylinder 23 is also supported by the shade holder 27 supporting the shade 28.

According to the present embodiment, the electric wire 9 for connecting the output of the human body sensor unit 1 to the control circuit unit 2 through the hole 8 formed in the metal plate 7 serving as the case of the control circuit unit 2 is connected to the metal plate. 7 is formed so as not to touch the edge of the hole 8 formed in the metal plate 7 by passing through the hole 10 formed in a part of the insulating plate 4 located on the inner surface side of the insulating plate 4. The extremely thin tape-shaped electric wire 9 can be easily protected without relying on a conventional protective tube.

From another viewpoint, the present embodiment is an electronic device in which an electric wire 9 is passed between the first block 1 and the second block 2, wherein the second block 2 is at least connected to the printed circuit board 5. A metal plate 6 having holes 8 through which the electric wires 9 are formed, and an insulating plate 4 interposed between the printed circuit board 5 and the metal plates 6 and 7. The electronic device is configured to be passed through a hole 10 formed in a part of the metal plate 4 and not to touch an edge of the hole 8 formed in the metal plates 6 and 7, so that the electric wire 9 can be easily protected. .
