Problems solved by technology
In addition, when the structure in which the circuit board 98 is fixed by using the claw piece 96a, although the danger of the cover case 95 falling from the bottom case 92 can be avoided by using the claw piece 96a, it will hinder the fixing of the circuit board 98.
[0012] It can be seen that the above-mentioned existing electrical equipment, discharge lamp lighting device and lighting fixture obviously still have inconvenience and defects in product structure, manufacturing method and use, and need to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve

The object of the present invention is to provide an electrical equipment which can properly realize the fixing function of a circuit substrate and prevent shedding of an enclosure and a bottom shell. The electrical equipment of the present invention comprises: a bottom shell 2, an enclosure 5, an insulating sheet 3 and an electrical circuit, wherein the bottom shell is in a launder shape formed by a bottom portion and a pair of side wall portions continuously formed upward from two sides of the bottom portion, and a pair of side wall portions are respectively arranged with a through hole portion 10; the enclosur has a top plate portion, a pair of side plate portions overlapped with the pair of the side wall portions of the bottom shell 2 and continuously formed from two sides of the top plate portion, and a claw hole portion provided with a claw portion, wherein the claw portion is folded in the inner part of the bottom shell 2 via the through hole portions 10 formed on the pair of side wall portions of the bottom shell 2, thereby holding the circuit substrate; the insulating sheet is arranged along the inner side surfaces of the bottom shell 2 and the enclosure 5, and the end portions are overlapped; and the electrical circuit is composed of a circuit substrate 6 mounted with electrical parts, and the circuit substrate 6 is arranged at the bottom surface side of the bottom shell 2 via the insulating sheet 3.
Description
Technical field [0001] The present invention relates to an electric device having a structure in which a circuit board mounted with an electric device is held in one casing of a box shape and the other casing of the box shape is connected to each other, and a discharge lamp with such a structure A discharge lamp lighting device for lighting, and the present invention further relates to a lighting fixture constructed using the discharge lamp lighting device. Background technique [0002] In a discharge lamp lighting device, which is an electrical device for lighting a discharge lamp such as a fluorescent lamp, a device called an electronic ballast is used. The structure of this ballast is that a circuit board on which electrical components are mounted is arranged between a metal base case and a cover case, and these cases are connected to each other. [0003] In the conventional discharge lamp lighting device, a stop groove and a connecting through hole are formed on the bottom she...
