この発明は放電灯用安定器、特に２灯点灯に用いる放電
灯用安定器の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ballast for a discharge lamp, and particularly to a method for manufacturing a ballast for a discharge lamp used for lighting two lamps.
放電灯２灯を点灯するための点灯装置として第１図に示
すような構成が使用される。A configuration as shown in FIG. 1 is used as a lighting device for lighting two discharge lamps.
同図において、Ｌ、、Ｌ２は放電灯、Ｔは安定器で、１

Secondary coil j/L-Ti and two secondary coils T21, T
22. The primary coil Ti is connected to a lighting power source and is also connected in series with each of the secondary coils T24 and T22, and the discharge lamps Li and L2 are lit by applying each secondary voltage to each of them. .

して側脚を打抜くことによつて安定器を製造することを
目的とする。As mentioned above, this kind of ``0'' ballast T consists of one ``0'' ballast T.
It is necessary to configure the secondary coil Ti and the two secondary coils T21 and T22 by winding them around a single ballast core, so as shown in Figure 2, the I-shaped central leg A and the outer leg B,
C, a ballast core J is constituted by two side legs H having pass core parts E and F and a yoke part G15, and a primary coil Ti is connected between the pass core parts E and F, and each outer leg part Secondary coils T21 and T2 are installed between B and C and each path core section E and F.
I am trying to place 2. In addition, each pass score section E,
A gap is formed between F and the central leg A20. By the way, the above-mentioned central leg A can be made by simply punching out steel plates in an I-shape and laminating them, but the side legs H have outer leg parts B and C and pass core parts E and F combed against the yoke part G. Since they are lined up in a shape, if these were simply punched out from the steel plate 25, scraps would be generated.
It is extremely uneconomical. The object of the invention is to manufacture a ballast by stamping out side legs without any scrap.
３０以下この発明の実施例方法を説明する。30 An example method of the present invention will be described below.

る。Fig. 3 shows a punched diagram of the side leg steel plate, in which the lengths of each outer leg part B and C of the side leg H are D, and the lengths of both pass core parts E of the yoke part G are
, When the width between F is d, prepare a steel plate 1 whose width is (D + d), and punch out one side edge IA of the steel plate 1 in sequence according to the solid line with the diagonal lined part as a 35 standard. A side leg steel plate 10 is obtained. After that, the remaining portion left unmolded is cut along the dotted lines to obtain the side leg steel plate 10A.

間をｄ＋Δｄとしてある。As a result, side leg steel plates of the same shape are punched out using a scratch press. By laminating the obtained side leg steel plates, the side leg H shown in FIG. 2 can be constructed. To explain the dimensions of one of the hatched parts, let us say that the widths of the outer leg parts 2 and 3, the pass core parts 4 and 5, and the distance between each outer leg part and the adjacent pass core part are all P. , the width between both pass core parts 4 and 5 is 2P, the length of the outer parts 2 and 3 is D, and the length of the pass core parts 4 and 5 is D-Ad (however, Ad is the gap length of the gap K and is approximately 0.4

鋼板を打抜くことができるようになる。Therefore, each shaded portion corresponds to the side leg steel plate 10.
has the same shape as the side leg H shown in FIG. Steel plate 1 has its width w
is D+d, so the length of the remaining portion after sequentially punching out the portions 10 from the other side edge 1B of the steel plate 1 is:
From the position indicated by the dotted line, D. d+/
D. D-/D,. d,. D-Zd,. d+/D,. It becomes D. Therefore, the side leg steel plate 10A obtained by cutting along each dotted line has the same shape as the side leg steel plate 10, and thus the side leg H. The position of the dotted line is at the exact half point of the remaining portion remaining between the previously punched portions 4 and 5 of the pass core. As a result of the above, the steel plate for the side leg H can be punched out without any scrap.

る打抜きも可能であるといつた効果を奏する。It is advantageous if the longitudinal direction of the steel plate 1 is aligned with the roll direction, since all the punched steel plates can be stacked in alignment with the roll direction. Furthermore, it is convenient to make small holes in the adjacent corners M of the adjacent parts 10 before punching out the parts 10, since it is possible to prevent the formation of burrs during punching. As detailed above, according to the present invention, when manufacturing a ballast for two lights,
The comb-shaped side legs can be punched out of a steel plate using a scratch press, so the steel plate can be used without waste, and if necessary, it is also possible to punch the steel plate in the same roll direction. be effective.
