【Example】

 An embodiment of the present invention will be described with reference to FIGS. In this embodiment, a light receiving element that detects ambient illumination, a control unit that controls the supply of power to the illumination load according to the ambient illuminance detected by the light receiving element to control the operation of the illumination load, and a circuit This is an integrated unit of the circuit section consisting of a power supply section that supplies power to the section. Hereinafter, this unit will be referred to as a circuit unit A.

As shown in FIG. 3, the circuit unit A uses a phototransistor P T as a light receiving element and a triac TR as a switching element of a control unit. That is, the ON / OFF or conduction angle of the triac TR is controlled according to the ambient illuminance detected by the phototransistor PT, and lighting control or lighting control of the lighting load or dimming control is performed.

The circuit components of the control unit including the phototransistor PT and the triac TR, and the circuit components of the power supply unit are mounted on the printed board 1. Here, since the TRIAC TR generates a large amount of heat, the radiating plate 3 is used to radiate heat. A plug blade 2 for power input and load control output is integrally attached to the printed circuit board 1. Here, there are three blades 2, and the negative electrode line of the power source and the load control output are commonly connected to one blade 2.

The case 4 for accommodating the circuit block is made of synthetic resin and is formed in a box shape with an open top surface. The lower ends of both side surfaces are curved so as to have a rounded bottom end. It has a good design. A lighting window 4a is provided on the lower surface of the case 4 at a position corresponding to the light receiving surface of the phototransistor P T. The lighting window 4a is closed by a light-transmitting cover 4b as shown in FIG.

A thick holder 7 having an insertion hole 7 a through which the blade 2 is inserted is attached to the upper opening of the case 4. A protrusion 7b is formed on the side surface of the holder 7, and the holder 7 is fixed to the case 4 by press-fitting the protrusion 7b into the press-fitting hole 4d of the case 4. Further, as shown in FIG. 4, the locking claws 2a are locked to the holder 7 as shown in FIG. 4 with the locking claws 2a formed at the base of the blade 2 and the holder 7 attached to the upper opening of the case 4. It serves to firmly fix the holder 7 and to prevent the holder 7 from coming off.

The pedestal B to which the circuit unit A is connected is installed on the outer wall surface of the house, and the housing 10 has a flat plate-shaped pedestal portion 10a and an upper portion of the pedestal portion 10a. It has a structure including a storage portion 10b formed by bulging. Here, the storage part 10b has an open bottom surface, the blade receiving part 13 is arranged in the opening part, and the circuit unit A is pushed up along the pedestal part 10a, and the circuit unit A is inserted into the opening part to insert the blade. The structure is such that the blade 2 is connected to the receiving portion 13. With such a storage structure, the waterproofness of the connection portion between the circuit unit A and the blade receiving portion 13 can be maintained.

As shown in FIG. 2, the housing 10 is mounted on the outer wall surface with a wall-mounting mounting frame 14 having a packing 15 integrally mounted on the periphery thereof interposed. . By biting the packing 15 in this manner, it is possible to ensure waterproofness of the opening for a wire provided in the outer wall surface. As shown in FIG. 5, the blade receiving portion 13 includes a pedestal 14 made of an insulating material and a blade receiving spring 15 attached to the pedestal 14 to receive the plug blade 2 of the circuit unit A. The blade receiving spring 15 is attached to a storage portion 17 formed on the pedestal 14. Here, the lead wire 18 is soldered and connected to the portion projecting from the upper surface of the spring piece 15, and the lead wire 18 is connected to the terminal block 20.

6 (a), (b) between the projecting portion from the upper surface of the blade receiving spring 15 for outputting power and for supplying power when the illumination load of the blade receiving portion 13 is turned on. As shown in b), a conductive piece 16 having a spring property is interposed. When the circuit unit A is pulled out, the conductive piece 16 short-circuits the output portions of the blade receiving springs 15 for output and power input to light the lighting load, as shown in FIG. 7B. When the circuit unit A 1 is connected, the conductive piece 16 is pushed upward as shown in FIG. 7A to release the short-circuited state. In other words, when the lighting load is not lit, it is possible to easily understand whether the lighting load side or the circuit unit A side is abnormal by attaching or detaching the circuit unit A.

The output of the blade receiving portion 13 is connected to an external power line such as a power line and a load line by relaying the terminal block 20. As shown in FIG. 7, the terminal block 20 accommodates a terminal plate 21, a lock spring 22 and a release button 23 in a terminal case 25 in which three terminal accommodating portions 25a are formed from the lower surface, and a terminal is provided on the lower surface. It is formed by covering the cover 26. The lock bar 22 and the release button 23 are structured to be housed in the terminal plate 21, and the terminal plate 21 is integrally provided with the connection terminal 21a of the lead wire 18 for connection with the blade receiving portion 13. Is formed.

This terminal block 20 is well known in the art. When an external wire whose coating has been stripped is inserted into the wire insertion hole 24, the core wire portion is formed by the terminal plate 21 and the locking spring 22 arranged inside. The elastic clamping is performed to connect the electric wires. The locking spring 22 is locked so as to bite into the core wire to prevent the electric wire from coming off. Also, the release button 23 can be used to release the locked state with the core wire of the locking spring 22 and the electric wire can be removed. FIG. 8 shows a connection state between the terminal block 20 and the blade receiving portion 13.

If the circuit unit is unitized as in this embodiment and can be connected to the pedestal B by a so-called plug-in method, the circuit unit can be commonly used regardless of the intended use. That is, if a blade receiving portion 13 that receives the blade 2 of the circuit unit A and is connected to the load control line and the power line is provided on the pedestal B side that is attached to the outer wall of the house, the electric pole, or the pole, The circuit unit can be used in common by only changing the structure of the pedestal B side. Therefore, it is possible to eliminate the waste and trouble of completely redesigning according to the intended use.

Moreover, by making the circuit unit A detachable in this way, in the event of a circuit abnormality, the circuit unit A can be replaced and the maintenance is facilitated. In addition, if several types of circuit units A are characteristically created, there is an advantage that the user's request can be met only by replacing the circuit units A.
