This is a solder-connected capacitor for preventing electromagnetic interference, and its installation is regulated by the technical standards of the ministerial ordinance of the Electrical Appliance and Material Control Law, and its capacitance is 0.006μF to 0.1μF. Reference numeral 9 denotes a reflector plate that covers the lower opening of the device main body 1, and its peripheral end is fixed to the peripheral end of the device main body 1, and holes are formed through which the glow starter 4 and the miniature bulb 6 are inserted. 10 is an upper shade fixed to the instrument main body 1; 11 is attached to this upper shade;
A lower shade 12 covers the lower part of the instrument body 1.
an annular fluorescent lamp supported by a fixture (not shown) attached to the lamp, having a pair of electrodes at each end;
and 4 electrically connected to each of these electrodes.
It has a socket part 13 equipped with a real lamp pin. Reference numeral 14 denotes a socket that is attached to a lamp pin in the socket portion 13 of the fluorescent lamp 12, and as shown in FIGS. 3 and 4, the socket body 15 is made of resin and has four insertion holes 15a to 15d. Four fitting terminals 16a to 16d housed within the socket body 15 and provided corresponding to the four insertion holes 15a to 15d.
and four lead wires 18a to 18d which are respectively crimped and connected to crimp parts 17a to 17d integrally formed on the upper part of these four fitting terminals 16a to 16d.
It consists of a fluorescent lamp 12
The four lamp pins are inserted into the insertion holes 15a to 1, respectively.
5d, and are electrically connected to the fitting terminals 16a to 16d and mechanically held, and the other ends of the lead wires 18a to 18d are inserted into insertion holes formed in the reflective plate 9, respectively. It is inserted into the instrument main body 1 through the main body 1 and connected to the ballast 2, the glow starter 6, and the switch 7. 19 is a ceiling 2 fixed to the ceiling surface 20
1 is attached to a hook ceiling; 22 is a power cord derived from this hook ceiling for supplying power to the fluorescent lamp 13, etc.; and 23 is a pull string for operating the switch 7.

The electrical connection is made by connecting one side of the power cord 22 to the ballast 2 as shown in FIG. 12 and connected in series from the other electrode of the fluorescent lamp 12 to the mating terminal 18b of the socket 14, one of the leads 18 18b, and the other of the power cord 22 via the switch 7. In addition to configuring the circuit, a parallel circuit of a glow starter 6 and a capacitor 8 for preventing electromagnetic interference is connected between a pair of electrodes of a fluorescent lamp, and a miniature bulb 6 is connected between one side of the power cord 22 and the switch 7. It is a familiar thing.

In the lighting equipment configured in this way, as mentioned above, the electromagnetic interference prevention capacitor 8 is connected in parallel with the glow starter 6, based on the technical standards of the ministerial ordinance of the Electrical Appliance and Material Control Act. For installation, first connect the lead wires 18c and 18 of the socket 14 connected to the socket 3 for the gross starter.
After inserting or intertwining both terminals 8a, 8a of the electromagnetic interference prevention capacitor 8 with the attachment terminals attached to the terminals d, connect the attachment terminals of the lead wires 18c, 18d and both terminals 8 of the electromagnetic interference prevention capacitor 8.
a and 8a are simultaneously connected to the glow starter socket 3 by soldering.

However, in the case of this lighting equipment, after the terminals 8a, 8a of the electromagnetic interference prevention capacitor 8 are entwined with the mounting terminals of the lead wires 18c, 18d and connected to the glow starter socket 3 by soldering, the electromagnetic interference prevention capacitor 8 is installed. Since the capacitor 8, the socket 3 for the gross starter, the socket 5 for the bulb, the ballast 2, the switch 7, and the power cord 22 are attached to the instrument body 1, it is best to automate the attachment of these parts to the instrument body 1. It was difficult.

In other words, the process of inserting or interlocking both terminals of the electromagnetic interference prevention capacitor 8 becomes an obstacle to automating assembly. Moreover, it also has the disadvantage that the capacitor 8 for preventing electromagnetic interference cannot be connected by crimping.

This idea was made in view of the above points, and in a lighting fixture having a capacitor for preventing radio wave interference, the capacitor for preventing radio wave interference is housed in a socket that is attached to the socket part of an annular fluorescent lamp. In this way, the purpose is to enable automation of the assembly of electrical components such as ballasts to the main body of the device.

An example of this invention is shown below in Figures 6 to 10.
This will be explained based on the diagram. 15 is four insertion holes 15
a to 15d, and these four insertion holes 15a to 1
5d, a fitting terminal housing part 15e in which four fitting terminals 16a to 16d are stored, and a resin-molded socket body having a space part 15f above the fitting housing part 15e; 8 denotes this socket body. Lead wires 18c, 18 are housed in the space 15f, and both terminals 8a, 8a are connected to the gross starter 6.
A crimp portion 17 is soldered to the tip of each of the fitting terminals 16c and 16d and is integrally formed with the fitting terminals 16c and 16d.
This is a capacitor for preventing electromagnetic interference that is crimped and connected at points c and 17d.

The configuration and circuit configuration other than the socket 14 are the same as those of the conventional example shown in FIGS. 1 to 5.

The connections between both terminals 8a, 8a of the electromagnetic interference prevention capacitor 8, lead wires 18c, 18d connected to the gross starter 4, and crimp portions 17c, 17d of the fitting terminals 16c, 16d are first shown in FIG. Both terminals 8a, 8a of the electromagnetic interference prevention capacitor 8 and the tips of the lead wires 18c, 18d are connected by solder 23 as shown in FIG. 16
The crimping portions 17c and 17d at the crimping portions 17c and 16d are aligned and crimped and connected.

Note that the first solder connection was lead wire 18.
Since strands c and 18d are usually stranded wires, the stranded wires are also soldered to each other to prevent them from coming apart when crimped and connected at the crimping portions 17c and 17d.

Therefore, the electromagnetic interference prevention capacitor 8 is housed in the socket 14 and does not need to be attached to the appliance body 1, so that it is possible to automate the attachment of electrical components such as the ballast 2 to the appliance body 1, and It is also possible to automate the connection between the terminals 8a, 8a of the electromagnetic interference prevention capacitor 8, the lead wires 18c, 18d, and the crimp portions 17c, 17d of the fitting terminals 16c, 16d.

As described above, this invention is based on a lighting device having a capacitor for preventing radio interference, in which the capacitor for preventing radio interference is housed in a socket that is attached to the socket part of an annular fluorescent lamp, and both terminals is stored in this socket.
Since the device is connected to two of the two fitting terminals, it is possible to automate the assembly of electrical components such as a ballast to the device body.
