Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for assembling a lighting fixture, and more particularly to an improvement in a method for connecting a ballast terminal to a connecting conductor of a wiring block fixed to the fixture body.

[Background technology]

In general, a lighting fixture for an annular fluorescent lamp is made up of a bottomed cylindrical main body portion and a cover portion (reflector plate portion) that have a flange portion at the opening edge, and are fixed such that the respective flanges abut each other. In the main body of the instrument,
The ballast, pull switch, socket for the glow starter, and socket for the miniature bulb are housed, wiring is done between them using vinyl wire, and an annular fluorescent lamp is attached to the socket led out from these sockets. It is composed of a shade placed on it.

By the way, with this lighting fixture, the pull switch, glow starter socket, miniature bulb socket, etc. are individually housed and fixed in the fixture body, and the wiring between them is done using vinyl wire, so it takes a lot of effort to assemble. There is a problem that not only does it require a lot of man-hours, but it is also difficult to mass-produce.

For this reason, in order to reduce costs by automating assembly and improving mass production, various wiring blocks have been proposed in which a pull switch, a glow starter socket, and a miniature bulb socket are combined into one block.

For example, Japanese Utility Model Application Publication No. 53-13456 has two insulating plates with a pull switch, a socket for a glow starter,
In addition to integrally forming the miniature ball socket, the wiring is connected between each component using a circuit network made by punching a metal plate, and the circuit network is integrally connected to the circuit network using two insulating plates. A wiring block is disclosed in which an external terminal formed on an insulating plate is held so as to protrude from the side of the insulating plate.

According to this wiring block, the pull switch, glow starter socket, bulb socket, external terminal, etc. are wired in advance using a circuit network made by punching metal plates, so when assembling the lighting equipment, The number of wiring locations using vinyl wire can be significantly reduced. As a result, assembly can be easily automated, and mass productivity and cost can be improved.

However, in this wiring block, the circuit network and external terminals are integrally formed by punching from a single metal plate, and the external terminals are located outward from the side of the circuit network. Due to the fact that it is overhanging the
When packaging wiring blocks, there is a problem in that not only a large wide case is required, but also transportation costs are high.

In addition, the metal plate for punching the circuit network and external terminals needs to be wide enough to cover the overhanging parts of the external terminals. Since most of the wiring is scrap, there is also the problem that the cost of the wiring block increases.

Furthermore, since the external terminals protrude outward from the sides of the insulating plate, they are easily deformed during handling and transportation. Therefore, even if the wiring block is fixed to the device body, the tips of the external terminals do not come into contact with the ballast terminals, resulting in the problem that soldering cannot be performed reliably.

[Disclosure of the invention]

Therefore, an object of the present invention is to effectively reduce the packaging volume of wiring blocks with a simple structure, and to
It is an object of the present invention to provide a method for assembling a lighting fixture that can reliably connect a connecting conductor to a ballast terminal.

A feature of the present invention is that a pull switch, a glow starter socket, and a miniature ball socket are integrally formed on one of the plurality of insulating members, and
Each component is interconnected by a circuit network formed by punching a metal plate, and a plurality of connecting conductors are inserted from the circuit network sandwiched between a plurality of insulating members so as to penetrate one of the insulating members and stand almost vertically. A step of fixing the wiring block to the device body, a step of bending the plurality of connection conductors standing upright on the wiring block so that their tips contact the ballast terminal, and a step of checking the bending state of the connection conductors. and electrically and mechanically connecting to the ballast terminal while maintaining the ballast terminal.

According to this invention, since the connecting conductor in the wiring block is led out so as to be substantially upright on one of the insulating members, deformation during handling and transportation can be significantly reduced. For this reason, connection with the ballast terminal during the assembly process can be made reliably.

Moreover, when the connecting conductor is connected to the ballast terminal, the tip of the connecting conductor is pressed so as to come into contact with the ballast terminal, which combines with the above-mentioned deformation prevention effect of the connecting conductor to stabilize the connecting conductor. It can be electrically and mechanically connected reliably to the terminals of the device.

In addition, since the connecting conductor stands upright on one insulating member, when storing the wiring block in a packaging case, there is no outward protrusion from the side of the insulating member, so the width can be reduced. Narrow packaging cases can be used. For this reason, not only packaging costs but also transportation costs can be effectively reduced.

In particular, if the connecting conductor is provided separately from the circuit network, it is possible to improve material removal during punching from each metal plate and to reduce costs.
