Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture, and more particularly to improving the electrical connectivity of a terminal between a switch block disposed within the fixture body and a discharge lamp ballast.

In general, this type of lighting equipment has a switch block, which integrates a pull switch, a glow lamp socket, etc., and a discharge lamp ballast, for example, in the bottom of a bottomed cylindrical equipment body, and a strip-shaped device that extends closer to each other. The free ends of the terminals are arranged so that they overlap, the overlapping parts of the terminals are spot welded, and then a cover is attached to the opening side of the device body.

By the way, welding the terminals of the switch block and the discharge lamp ballast requires a first welding electrode inserted through a hole formed in the bottom of the device body opposite to the overlapping part of the terminal, and a first welding electrode placed on the opening side of the device body. However, positioning the first welding electrode to insert it into the hole in the device body is troublesome, and it is not suitable for mass production. Because the welding electrode has a long distance to the overlapping part of the terminal, it is necessary to use a fairly thick one for strength, and an even larger hole is formed at the bottom of the device body, which spoils the appearance. Not only that, but there is also a problem that it is undesirable from the viewpoint of electrical appliances.

In view of these points, the present invention provides a lighting fixture in which the terminals of a switch block and a discharge lamp ballast can be easily and efficiently welded without damaging the appearance of the fixture itself. in,
Examples will be described below.

In the figure, reference numeral 1 denotes a device main body configured, for example, in the shape of a cylinder with a bottom, and a flange portion 1a is integrally formed around the opening of the device main body. and,
For example, linear notches are formed at equal intervals in the flange portion 1a. 2 is a switch block, which includes, for example, two upper and lower insulating substrates 3, a pull switch 4, a socket 5 for a glow lamp,
5, a socket 6 for a safety ball, and an L-shaped terminal 7 led out from between two insulating substrates 3, 3. The switch block 2 is placed at the bottom of the device body 1 so that the pull switch 4 is located approximately at the center of the device body 1, and the rising portion 7a, which is the free end of the terminal 7, is on the opening side of the device body 1. is fixed. Reference numerals 8 and 8 refer to a discharge lamp ballast, in which a rising portion 9a, which is the free end of an L-shaped terminal 9 extending from the bottom of the appliance body 1, overlaps with a rising portion 7a of the terminal 7 of the switch block 2. or are arranged so that they are close to each other. The rising portions 7a and 9a of these terminals 7 and 9, which overlap or are close to each other, are spot welded from the opening side of the instrument body 1. Reference numeral 10 denotes a cover having a cylindrical shape with a bottom, for example, and is attached to the opening side of the instrument body 1. 11 is a shade attached to the flange portion 1a of the instrument body 1, and 12 is an annular fluorescent lamp. Note that a cord a is led out from the top of the device body 1, and is connected to sockets 5, 5 and 6.
Glow lamps b, b and safety bulb C are attached to the.

In this way, the switch block 2 and the discharge lamp ballasts 8, 8 are provided with the L-shaped terminals 7, 9, so that by simply fixing each to the bottom of the appliance body 1, the rising parts 7a, 9a can be connected together. or close to each other. For this reason, the rising portions 7a, 9
By holding a between a pair of welding electrodes, welding can be performed easily and reliably.

In particular, since welding of the terminals 7 and 9 is performed on the opening side of the device body 1, there is no need to insert one side of the welding electrode into the hole in the device body as in the conventional case, making the welding work more efficient. This can be done in a number of ways, increasing the effectiveness of mass production.

Moreover, since there is no need to form a hole in the bottom of the device body 1 for inserting the welding electrode, not only can the appearance of the device body 1 be improved, but also live parts can be prevented from being exposed from above the electrical appliance. This is preferable in this respect.

In the present invention, the shapes of the appliance body and the switch block can be changed as appropriate, and the number of discharge lamp ballasts used can be increased or decreased as appropriate. In addition to bending the free end portion of the terminal into an L shape, the free end portion that simply extends linearly may be twisted and bent so as to be approximately perpendicular to the base portion.

As described above, according to the present invention, the terminals of the switch block and the discharge lamp ballast can be welded easily and efficiently without any damage to the appearance of the device body.
