Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lighting fixtures such as poppy light lamp fixtures.

In the case of follower, poppy, light lamp equipment, etc., the main body of the wiring equipment is equipped with a glow socket, night light socket, switch, etc., as well as a circuit section, and the lead wire of the lamp socket is connected to the terminal of this circuit section to form a unit. A wiring fixture is formed and the wiring fixture is connected to a chassis-mounted ballast.

The heat dissipation effect of the pair of ballasts is greatly impaired, and
Wiring equipment receives direct heat conduction due to close contact with the ballast,
Problems such as parts deterioration are likely to occur.

Furthermore, as shown in Japanese Utility Model Application Publication No. 48-114271, a pair of ballasts are attached to the chassis, and a wiring block is attached to the chassis between the pair of ballasts by its attachment part, and wiring is wired to the terminals of the ballast. Some have the terminals of the block crimped and a cover attached to the chassis.

However, in this method, the wiring block is positioned and fixed independently with respect to the main body of the device, so misalignment between the ballast and the wiring block causes bending of the terminal portion, which tends to cause soldering defects. The present invention has been made in view of the above-mentioned points, and aims to easily and reliably connect and fix a ballast to a wiring device, and to improve the heat dissipation effect of the ballast. It is.
