In recent years, what is called a quick connection terminal has been used as this terminal in order to automate the assembly of the lighting fixture 2 and the like and improve the workability of the assembly.

FIG. 10 shows an example of a conventional quick connection terminal 11, and FIGS. 11 and 12 show a second conventional example of a fluorescent lamp ballast 1 using the quick connection terminal 11 shown in FIG. is there. The quick-connecting terminal 11 is formed integrally by bending a spring-like conductive member, and presses and holds the inserted electric wire 12 at one end thereof.
a, an electric wire contacting piece 11b that is opposed to the quick-connecting spring piece 11a, and to which the wire 12 pressed by the quick-connecting spring piece 11a contacts, and an upright connecting the quick-connecting spring piece 11a and the wire contacting piece 11b. A wire insertion hole 11d, which is a wire insertion portion, is provided on the side of the upstanding piece 11c on the side of the wire abutting piece 11b, and an end of the wire abutment piece 11b opposite to the upstanding piece 11c is provided with a coil frame. Inserted into 4 and locked. In other words, the standing piece 11c rises from the wire contact piece 11b, forms a substantially L-shape with the wire contact piece 11b and the rising piece 11c, and has a wire insertion hole 11d through which the wire 12 is inserted near the base of the rising piece 11c. Then, the quick-connecting spring piece 11a is bent from the tip of the upstanding piece 11c toward the wire contact piece 11b, and the tip is closely opposed to the wire contact piece 11b so as to press and clamp the inserted wire 12. It is configured.

The quick-connecting terminal 11 is provided on one side surface of the coil frame 4 near the base plate 6 with the upright piece 11c facing the upper non-base plate 6 side. Standing piece
The end opposite to 11c is inserted and latched, and is mounted so as to substantially cover the other five surfaces except for the electromagnetic device main body 8 side and to have a wire insertion guide hole 13a at a position facing the wire insertion hole 11d of the quick connection terminal 11.

FIG. 13 shows a third conventional example of the fluorescent lamp ballast 1. The difference from the second conventional example is an insulating cover 13, and the other is different from the second conventional example. It is configured similarly. The insulating cover 13 has a rear side wall 13b on the side of the electromagnetic device main body 8;
Is divided into at least two parts, for example, an upper cover and a lower cover.
When assembling, the lower cover is mounted from the upright piece 11c side, which is the front side of the quick-connecting terminal 11, and the upper cover is mounted from the non-base plate 6 side, which is above the quick-connecting terminal 11.

FIG. 14 shows a fourth conventional example of the fluorescent lamp stabilizer 1. The difference from the second conventional example is the mounting position of the quick connection terminal 11, and the other is the second conventional example. Is configured in the same manner as the conventional example. The quick connection terminal 11 is on the opposite side of the coil 5 on one side of the coil frame 4 and on the upper side of the fluorescent lamp ballast 1 which is an electromagnetic device, that is, the non-coil 5 of the coil frame 4
The upright piece 11c is mounted on the side opposite to the base plate 6 with respect to the iron core 3 so as to hang from the wire contacting piece 11b. Similarly, the insulating cover 13 is attached.
