Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug for a wiring duct and a lighting fixture, and more particularly, to a plug for a wiring duct for electrically and mechanically connecting a lighting fixture to the wiring duct for mounting. The present invention relates to a lighting fixture attached by a wiring duct plug.

[0002]

2. Description of the Related Art Conventionally, in a wiring duct plug for electrically and mechanically connecting a lighting fixture to a wiring duct and mounting the wiring duct, for example, a conductor is made of a synthetic resin-made duct body in which a conductor is formed by a rail. The power receiving part on the wiring duct plug side is electrically connected to the conductor by operating a lever or the like, and the mechanical connection part on the wiring duct plug side is received by the duct body. In some cases, the wiring duct plug can be suspended at an arbitrary position in the longitudinal direction of the wiring duct by mechanically connecting the plug to the wiring duct. When the lighting fixture is attached to the wiring duct using the above-described wiring duct plug, the lighting fixture may be temporarily held by a wire or the like in order to prevent the lighting fixture from dropping.

[0003]

However, in the above conventional example, the following problems occur.

When mounting a lighting fixture to a wiring duct using the above-described wiring duct plug, an installer must operate the lever to attach the wiring duct plug to the wiring duct while supporting the lighting fixture. , And the workability deteriorates. In addition, in the case of installing a lighting fixture having a large weight or a lighting fixture having a large dimension, the workability is further deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of all of the above problems, and an object of the present invention is to provide a wiring duct plug and a lighting fixture that can improve workability for attaching the lighting fixture to the wiring duct. The cost is to provide.

[0006]

According to the first aspect of the present invention, there is provided a plug for a wiring duct which is electrically and mechanically connected to a wiring duct for mounting. A temporary holding portion is provided, and the wiring duct plug is mechanically temporarily held in the receiving portion of the duct main body by the temporary holding portion.

According to the second aspect of the present invention, in a lighting fixture attached by a wiring duct plug that is electrically and mechanically connected to the wiring duct and attached, the temporary holding portion is provided with an elastically deformable temporary holding portion. The lighting fixture is mechanically temporarily held in the receiving portion of the duct body.

[0008]

(Embodiment 1) A perspective view of a first embodiment according to the present invention is shown in FIG. 1, a side sectional view is shown in FIG. 2, and a wiring duct plug 1 is used for a lighting fixture 7. 3 is shown in FIG.

[0009] Plug 1 for wiring duct shown in this embodiment
Operates the lever 6 to electrically connect the power receiving unit 10 on the wiring duct plug 1 side to a conductor laid in a rail shape inside the duct body of the wiring duct 3; The temporary holding portion 2 of the wiring plug 1 is mechanically connected to the receiving portion of the duct main body, and the wiring duct plug 1 can be suspended at an arbitrary position in the length direction of the wiring duct 3. The temporary holding section 2 is provided with a protrusion A made of, for example, resin.

When the temporary holding portion 2 is inserted into the wiring duct 3, as shown in FIG. 2 (b), during the insertion process, the projection A is temporarily inwardly moved into the temporary holding portion 2 by elastic deformation. As shown in FIG. 2C, the protrusion A is restored by the elastic deformation of the resin, so that the protrusion A comes into contact with the plug holding portion 4 provided on the wiring duct 3 and the wiring duct 3 The wiring duct plug 1 is attached and fixed.

With the above construction, the wiring duct plug 1 can be easily attached to the wiring duct 3, and even if the lever 6 of the wiring duct plug 1 is released, the wiring duct 3 will be protruded. Since the lighting fixture is temporarily held by the portion A, the workability for attaching the lighting fixture to the wiring duct can be improved.

Although the slits 5 are provided on at least one side of the projections A so that the projections A can be easily elastically deformed, any structure that assists the elastic deformation of the projections A can be used. Alternatively, another configuration may be used. Further, the shapes of the temporary holding portion 2 and the plug holding portion 4 may be any shapes as long as the purpose is achieved.

(Embodiment 2) FIG. 4 is a perspective view and FIG. 5 is a side sectional view of a second embodiment according to the present invention in which a wiring duct plug is used for a lighting fixture 7.

The difference from the first embodiment shown in FIGS. 1 to 3 is that a temporary holding portion having an elastic force on the lighting fixture 7 (hereinafter, referred to as a temporary holding plate spring) is used instead of the temporary holding portion 2. 8, the temporary holding plate spring 8 is mechanically connected to the receiving portion of the duct main body, so that the wiring duct plug 1 can be hung at an arbitrary position in the length direction of the wiring duct 3. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

When the temporary holding leaf spring 8 is inserted into the wiring duct 3, the bent portion B of the temporary holding leaf spring 8 is temporarily elastically deformed during the insertion process as shown in FIG. As shown in FIG. 5C, the temporary holding plate spring 8 is restored by elastic deformation, so that the temporary holding plate spring 8 is connected to the plug holding portion 4 provided in the wiring duct 3.
And the lighting fixture 7 is attached to the wiring duct 3.

With the above configuration, the plug for the wiring duct can be easily attached to the wiring duct 3, and even if the lever 6 of the plug for the wiring duct is released, the lighting fixture 7 is kept on the temporary holding plate. Since the lighting fixture is temporarily held by the spring 8, workability for attaching the lighting fixture to the wiring duct can be improved.

The temporary holding plate spring 8 and the plug holding portion 4
May be of any shape as long as it achieves its purpose.

(Embodiment 3) FIG. 6 is a side sectional view of a third embodiment according to the present invention.

The difference from the first embodiment shown in FIGS. 1 to 3 is that a spring spring 9 is used between two projections A to assist the elastic deformation of the projections A. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

[0020]

According to the first aspect of the present invention, it is possible to provide a plug for a wiring duct at a low cost, which can improve workability for attaching a lighting fixture to the wiring duct.

According to the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, it is possible to provide a low-cost luminaire capable of improving workability for attaching the luminaire to the wiring duct.
