り、作業が煩雑であつた。 For example, in a discharge lamp ballast, a coil is fitted into one of a plurality of laminated cores, and these laminated cores are combined and housed and fixed in a case. As a joining method in this case, there is a method in which a resistance wire is interposed between the joining surfaces of both iron cores, and electric resistance welding is performed by energizing the resistance wire. However, in the past, a resistance wire was simply interposed between both cores, so the laminated core on the side without the coil had to be clamped to prevent the laminated state from collapsing, making the work complicated. .

A laminated core equipped with a coil and a laminated core without a coil are joined by electric resistance welding and housed in a case, and a resistance wire for electric resistance welding is attached to the latter laminated core. The resistance wire is wound at least once, and the case is provided with an engaging portion in which the resistance wire engages.

であつても良い。 The present invention will be described in detail below with reference to the illustrated embodiment. Fig. 1 and Fig. 2 show an example of a discharge lamp ballast. In the figures, reference numeral 1 denotes a ballast body, which is housed and fixed between a lower case 2 and an upper case 3. The ballast body 1 has a pair of C-type laminated iron cores 4, 4, an I-type laminated iron core 5, and a coil 6, and the coil 6 is fitted into the I-type laminated iron core 5. Each of the C-type laminated iron cores 4, 4
The I-shaped laminated core 5 has diagonal yokes 4 at both ends.
Resistance wires 7, 7 for electric resistance welding are provided on the a, 4a side.
Therefore, when joining these laminated cores 4, 4, 5, the I-type laminated core 5 is placed in the center, and the C-type laminated cores 4, 4 are placed on both sides of it, and then these laminated cores 4,
4, 5 in the direction of connection, each resistance wire 7,
7 to perform electric resistance welding.
Since the C-type laminated cores 4, 4 are firmly held by the resistance wires 7, 7, the laminated core pieces do not collapse and are extremely easy to handle. The I-type laminated core 5 has a coil 6 fitted in it, which prevents it from collapsing. The lower case 2 has a stepped portion 2 that receives the C-type laminated cores 4, 4 of the ballast body 1, as shown in FIG.
Groove-shaped engaging portions 8, 8 are formed in the lower case 2a, 2b, corresponding to the resistance wires 7, 7, and the resistance wires 7, 7 are engaged with these engaging portions 8, 8 to position the ballast body 1 relative to the lower case 2. Therefore, the ballast body 1 is fixed very reliably,
This prevents the upper case 3 from shifting out of position or falling off.
The claws 2 are formed on the side walls 2b of the lower case 2.
The engaging portions 8, 8 may be cut out.
抵抗線７，７は第４図に示すように２回或いは

れる。 FIG. 6 shows a combination of a pair of L-shaped laminated cores 9, 9 and a T-shaped laminated core 10. FIG. 7 shows a combination of a pair of C-shaped laminated cores 11, 11 and a ten-shaped laminated core 12, and two coils 6,
6 is fitted. FIG. 8 shows a pair of E-type laminated cores 13, 13, in which a coil 6 is fitted into the inner leg portion 13a on one side, and a resistance wire 7 is wound around the other side. FIG. 9 shows a combination of an E-type laminated core 14 and an I-type laminated core 15. In these cases as well, the same effects as described above can be obtained by winding the resistance wire 7 around the laminated cores 9, 11, 13, 15 on the side where the coil 6 is not provided as shown.
