Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mounting device for a power terminal block in a lighting fixture.

[Technical background of the invention and its problems]

Conventionally, as a means of attaching a power terminal block to a lighting fixture, as shown in FIG. There is a method of fixing the stabilizer case body 5 to which the main body 4 is fixed to the instrument main body 1 from the inner surface with rivets 6. Generally, when assembling a lighting fixture, the fixture body 1 is placed on an assembly conveyor,
Since the parts are attached while being moved, the method shown in FIG. 1 has good workability because screwing and riveting can be done from the inner surface of the instrument body 1, that is, from the upper surface of the workbench. However, the tip of the screw 3 protrudes from the outer surface of the device body 1, which has the disadvantage of injuring the operator or damaging the packaging material when packaging the product.
Moreover, the tips of the screws 3 protrude from the mounting surface of the instrument body 1 and become a hindrance to the mounting. Furthermore, in recent years, in order to reduce the weight of lighting equipment, there has been a trend to make the iron plate of the equipment main body 1 thinner, which has the disadvantage that the fixing force of the screws is insufficient and the installation of the terminal block 2 becomes unstable. In order to eliminate such drawbacks, there is a method of fixing the ballast 3 to the terminal block 2 from the outside of the device body 1 by screwing it onto the terminal block 2, as shown in FIG. Driving direction of rivet 6 and screw 3 to attach
Since the direction of installation is reversed, it is necessary to vertically change the instrument main body 1 on the assembly conveyor, resulting in a disadvantage that assembly work efficiency is deteriorated. Furthermore, in both cases of FIG. 1 and FIG. 2, the power supply terminal of the terminal block 2 and the ballast terminal 7 are connected by a lead wire 8, so there is a problem that the connection takes time and effort.

[Purpose of invention]

In view of the above-mentioned problems, the present invention combines a ballast case body with a ballast main body fixed inside the device body using a coupling tool from inside the device body, and further connects a power terminal block to the ballast case body with screws inside the device body. more fixed,
The tip of the screw protruding from the device body is covered with a protrusion formed on the device body, and the ballast terminal protruding from the ballast body is directly connected to the power terminal of the terminal block to connect the terminal block to the device body. This improves assembly workability, ensures secure fixing, eliminates the danger of screws protruding from the device body, and simplifies terminal connections.

[Summary of the idea]

The present invention includes a device body, a stabilizer case body that fixes the stabilizer body and is connected to the device body from within the device body via a coupling device, and a stabilizer case body that is connected to the stabilizer case body from within the device body to the device body. a power supply terminal block fixed with twisted screws, and a ballast terminal protruding from the ballast body, forming a bulging protrusion that bulges outward from the device body and covering the tip of the screw; Connect the power terminal of the terminal block directly, fix both the ballast case body and the power terminal block from the inside of the device body, and cover the tip of the screw protruding from the device body with the protrusion of the device body. This is a direct connection between the ballast terminal and the power supply terminal.

[Example of idea]

An embodiment of the present invention will be described with reference to FIGS. 3 and 4.

Reference numeral 1 denotes the main body of the device, in which a ballast 8, a power terminal block 2, and other components are installed.

The ballast 8 consists of a ballast main body 4 and a ballast case body 5 which is fixed to a mounting plate part 9, and the mounting plate part 9 of the ballast case body 5 is connected to the base plate part 10 of the instrument main body 1.
It is fixed to the device body 1 from within the device body 1 with a rivet 6 as a connector. Further, a pair of ballast terminals 11 and 12 are protruded from the ballast main body 4 at both ends thereof.

A pair of power supply terminals 13 are attached to the terminal block 2 at an interval equal to the interval between one of the ballast terminals 11, and the terminal block 2 has screws screwed into female screw holes 14 of the mounting plate part 9 of the ballast case body 5. 3, it is attached to the stabilizer case body 5 from the inside of the instrument body 1.

Note that the terminal block 2 is positioned in advance so that the position of the power supply terminal 13 is substantially superimposed on the position of the ballast terminal 11, and the power supply terminal 13 is superimposed on the ballast terminal 11, and is not welded, soldered, or caulked. Connected by etc.

Furthermore, a terminal block 2 is provided on the board portion 10 of the device main body 1.
A bulging protrusion 16 is formed in advance at the position where the tip 15 of the screw 3 to which the screw is attached protrudes, and the protruding tip 1
5 is covered. Also, the board part 1
0, a gap holding protrusion 17 is formed to bulge out at the same height as the bulging protrusion 16, and together with the bulging protrusion 16, a parallel gap is interposed between the device main body 1 and a mounting surface 18 such as a wall surface of a building. It's getting old.

Next, the operation of the above embodiment will be explained.

When the ballast 8 and the power terminal block 2 are attached, rivets 6 are driven into the top surface of the device body 1 being transported on the conveyor, and screws 3 are screwed in, and assembly work is performed in the same direction.
protrudes from the mounting plate portion 9 of the ballast case body 5 and into the bulging projection 16 of the fixture body 1.

[Effect of idea]

According to the present invention, a ballast case body to which a ballast body is fixed is connected to the ballast body via a coupling tool from within the ballast body, and a power terminal is connected to the ballast case body from within the ballast body using a screw. Since the base is attached, both the ballast case body and the power terminal block can be attached from the inside of the device body, that is, from the top surface of the device body sent by the assembly conveyor, using coupling tools and screws, which improves work efficiency. Furthermore, since the device body has a protrusion that bulges outward to cover the tip of the screw, the tip of the screw protruding from the device body may damage the operator's fingertips or damage the product packaging. This does not cause any trouble, and since the bulging protrusion creates a gap between the device body and the mounting surface, heat from the device body is radiated through this gap. In addition, since the power terminal block is screwed to the ballast case body, the installation stability is improved by screwing it to the ballast case body, which has a thickness of approximately 1 mm, compared to the device body which is 0.3 to 0.4 mm thick. In order to attach both the ballast body and the power terminal block to the ballast case body, the power terminal block is brought close to the ballast body, and the ballast terminal protruding from the ballast body is directly connected to the power terminal of the terminal block. It can make your work easier.
