Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power distribution track device arranged on a ceiling surface etc. and configured to supply power to lighting equipment etc. by connecting a power receiving plug. It has excellent dust-proofing effects even when installed in areas where a lot of dust is generated.

2. Description of the Related Art Conventional power distribution track devices of this type include those shown in FIGS. 1 and 2. Regarding its structure and method of use, a duct main body 2 with a compartment 1 on its upper surface has legs that can be deformed within the compartment 1, and a protection part 4 that hangs down from the legs 3 is a part of the duct. The opening 5 is closed to provide a dustproof effect. Then, as shown in FIG. 2, when the plug 6 is pushed up, the leg portion 3 deforms and the protective portion 4 rises, and by rotating the plug 6 900 times with the conductor T exposed, the plug blade of the plug 6 is removed. 8 and 8 are brought into contact with the conductors T and T so that electricity can be supplied. However, since the bottom surface of the protection part 4 is flat, if dust adheres to the bottom surface of the protection part 4 and contains moisture, when the plug is attached, the dust will pass between the left and right plug blades 8 and the current will flow. There was a risk that the current would flow and cause a short circuit. The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to prevent the gap between the plug blades when the plug is attached, even if moist dust adheres to the protective cover. An object of the present invention is to provide a power distribution track device with a cover that is less likely to cause a short circuit accident.

3 and 4 showing one embodiment of the present invention. In FIG. 3, on both inner surfaces of the duct body, which has a substantially U-shaped cross section and has an opening 10 for inserting a plug on the lower surface. Insulators 11 are protruded so as to face each other along the longitudinal direction, and a conductor 12 exposed inward is provided at the tip of the insulators 11 to form a power distribution track A.

B is an insulating cover made of synthetic resin material such as vinyl chloride, and the elastic legs 13 are deformable in the space between the top surface 14 of the power distribution track A and the insulator 11, and the elastic legs 13 Protective parts 15 that cover the conductor 12 are protruded from the legs 13 and 15, and a groove 16 is formed in the longitudinal direction between the protective parts 15 on both sides. FIG. 4 shows the state in which the plug is inserted. That is, when the head IT of the plug P enters the power distribution conductor A through the opening 10, contacts the protection part 15, and is further pushed up, the elastic leg part 13 of the cover B
is bent and deformed, the protective portion 15 is raised, and the conductor 12 is exposed. Then, rotate the plug P 900 times and
Electricity is supplied to the plug P by bringing it into contact with the conductors 12, 12. In this state, since a groove 16 is provided on the bottom surface of the cover B, the head 1 of the plug P
7 and the protection part 15 do not come in flush contact with each other, and even if the groove part 161/C is covered with dust, the gap between the plug blades 18
, 18 makes it difficult for short circuits to occur through dust. Furthermore, if the plug is connected and disconnected repeatedly, the conductor 12 and the plug blade 18 will wear out and the metal powder from both will adhere to the lower surface of the protective part 15, but the metal powder will not adhere to the groove part 16. A short circuit between the plug blades 18, 18 will not occur. As described above, according to the covered distribution track device of the present invention,
By providing a groove on the bottom surface of the protection part, the metal powder adhesion that occurs when attaching and detaching the plug is cut off by the groove, thereby preventing short circuit accidents between the left and right plug blades of the plug.
In addition, even if dust adheres to the bottom surface of the protective part, the dust does not come into contact with the head of the plug in the groove, so there is no short circuit between the left and right plug blades, and a safe power distribution path can be obtained. This has the advantage that it is possible to
