Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of wiring components having terminals such as outlets and switches.

For example, when attaching an outlet having a terminal as a wiring component to the main body of a lighting fixture, it is necessary to prevent hands, tools, etc. from touching the terminal.

For this reason, the conventional method has been as shown in FIGS. 1 and 2.

That is, in the figure, 1 is a main body of a lighting fixture formed in a substantially U-shape, and a mounting hole 2 is bored in one side of the main body 1.

This mounting hole 2 has a flange 3 larger than the mounting hole 2 at one end, a pair of terminals 5, 5 to which a lead wire 4 is connected at the other end, and has a substantially doglegged shape on the upper and lower surfaces. The outlet 7 is installed by inserting the outlet 7 provided with the fixing springs 6, 6 made of formed plate springs, and engaging the end of the fixing spring 6°6 with the peripheral edge of the mounting hole 2. Fix it to main body 1.

Thereafter, the terminals 5, 5 exposed inside the main body 1 are covered with a cover 8 formed in a substantially U-shape, and both ends of this cover 8 are screwed into screw holes 9a formed in the main body 1 with screws 9, 9. It was fixed by.

In addition, the main body 1 has the above-mentioned outlet 7 located around the mounting hole 2.
A display board 10 is attached that displays the allowable wattage.

However, according to the above configuration, although the work of attaching the outlet 7 and the cover 8 is a separate work, there is a problem in that the number of steps increases and productivity is reduced.

Furthermore, in order to fix the cover 8 to the main body 1 with the screws 9, it is necessary to provide the threaded holes 9a in the main body 1, which requires time and effort, and furthermore, the screws 9 protrude from the threaded holes 9a of the main body 1. There is also the risk of getting your fingers caught on the tip and getting injured.

The present invention was developed based on the above circumstances, and its purpose is to house wiring components such as electrical outlets in a container having a covering part that covers the terminals provided on the component. The housing is fixed to the main body by inserting it into the mounting hole formed in the main body, and the terminals provided on the wiring parts can be covered at the same time as the wiring parts are being installed. It's about providing structure.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 3 to 5.

In the figure, 11 is a lighting fixture. This lighting fixture 11 has a main body 12 formed in a cylindrical shape and a shade 13 joined to it, and accommodates lighting parts such as a lamp (not shown) inside, and has ends at both ends of the joined main body 12 and shade 13. Board 1
4 and 14 are fitted.

An attachment hole 15 is bored in one side of the main body 12, and an outlet 17 is attached to the attachment hole 15 as a wiring component housed in a container 16.

That is, this outlet 17 has a first flange 19 larger than the mounting hole 15 formed at one end of a substantially box-shaped base 18, as shown in FIG. A pair of insertion ports 20, 2 are provided on one end surface of the 18.
0 is formed.

Further, a pair of terminals 22.22 to which lead wires 21.21 are connected are protruded from the other end surface of the base body 18.
The spring material is bent into a U-shape, and both sides of the spring material are bent into a V-shape to form the fixing springs 23, 23. It is fixedly installed.

Note that the fixing spring 23 has its tip connected to the first collar 19.
It is formed in a length that is spaced a predetermined distance from the inner surface of.

On the other hand, the accommodating body 16 has a substantially rectangular cylindrical shape in which a accommodating portion 26 made of synthetic resin that accommodates the base 18 and a covering portion 27 that covers the terminals 22 and 22 connected to the accommodating portion 26 are integrally formed. The above-mentioned mounting hole 15 is provided at one end.
A second flange 28 is formed which is larger than the second flange 28.

Further, an opening 29 is formed in the upper surface of the container 16, and a groove 30 extending over the entire length in the longitudinal direction is formed in the lower surface.

Further, the upper side of the second collar 28 is formed larger than other parts, and this part serves as a display section 31 that displays the allowable wattage of the outlet 17.

After accommodating the outlet 17 in the accommodating body 16 formed in this way, if this accommodating body 16 is inserted into the mounting hole 15 formed in the main body 12, the outlet 17 is inserted through the opening 29 and the groove 30 of the accommodating body 16, respectively. A pair of protruding fixing springs 2
3 and 23 are elastically engaged with tongue pieces 15a and 15a formed on the upper and lower edges of the mounting hole 15, and the outlet 17 is fixed to the main body 12. A second flange 28 formed on the container 16 by the first flange 19 and the peripheral edge of the attachment hole 15 of the main body 12
is clamped, and this container 16 is also fixed to the main body 12.

Therefore, according to such a mounting structure for the outlet 17, the covering portion 27 of the container 16 allows the outlet 17 to be
Since the terminals 22 and 22 of the outlet 1 are covered,
Since the receptacle 17 can be attached and the terminals 22.22 can be covered by simply inserting the container 16 containing the holder 7 into the mounting hole 15, there is no need to cover the terminals 22.22 as a separate operation.

In addition, by using a part of the second collar 28 formed on the container 16 as the display section 31, a display board is required to display the performance of the outlet 17 separately from the installation work of the outlet 17 as in the past. There is no need to set one up.

Furthermore, a groove 30 is provided on the lower surface of the container 16 over the entire length in the longitudinal direction.
Since the groove 30 is formed, even if the lead wire 21.21 is connected to the terminal 22.22 of the outlet 17 in advance, the groove 30
The lead wires 21.degree. 21 can be easily led out from the container 16 through the.

Note that the present invention is not limited to the above-mentioned embodiment; for example, the wiring component may be not only an outlet but also a changeover switch, and in that case, the ON-OFF position of the switch may be displayed on a display section provided in the container. Just do it.

Further, it is clear that the main body to which the wiring components are attached is not limited to a lighting fixture, and the mounting structure of the present invention can be applied to any body in which the above-mentioned outlet or switch is provided.

As stated above, the present invention provides wiring components that have terminals.
The terminal is housed in a housing formed with a covering portion, and the housing is inserted into a mounting hole formed in the main body, and the wiring component is fixed to the main body with a fixing spring provided therein. At the same time, a second collar larger than the mounting hole formed in the housing is held between a first collar larger than the mounting hole formed in the wiring component and a peripheral edge of the mounting hole of the main body. This fixed it to the main body.

Therefore, according to such a mounting structure, it is only necessary to insert the wiring components housed in the container into the mounting hole of the main body.
Since there is no need to cover the terminals of the wiring components in a separate operation, productivity can be improved.

In addition, since the cover that covers the terminal is attached to the main body with screws as in the past, there is no need to provide a threaded hole in the main body, which improves work efficiency and achieves the above-mentioned advantages. There is no danger of getting your fingers caught on the screw protruding from the hole and drilling the hole.
