Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a sealing rosette, and particularly to a method for preventing short circuits or ground faults between different terminal plates in exposed type ceiling rosettes. Regarding what to prevent.

(Prior Art) A conventional sealing rosette of this type is composed of a main body and a plate to which the main body is attached, as described in, for example, Japanese Patent Laid-Open No. 61-99204.
A wire connection portion is formed with an opening on the lower surface, and the wire connection portion is provided with a pair of terminal plates of different polarity for sandwiching and connecting electric wires to the main body portion, and this terminal plate G: the electrically connected sealing blade holder is A hook such as a sealing cap formed on the plate portion is disposed along the side edge of the narrow hole portion of the blade insertion hole, and an insulating wall is formed between the terminal plates of different polarities. The joint between the lower edge of the main body and the inner bottom surface of the plate part, including the joint part between the lower edge of the insulating wall between terminal plates of different polarities and the inner bottom surface of the plate part, is in close contact with the main body part and the plate part. A structure was adopted that combined the In the conventional ceiling row set, the electric wire connecting portion of the main body is installed in a hole embedded in the surface such as a ceiling, and the plate portion is installed with the plate portion in contact with the ceiling surface.

(Problems to be Solved by the Invention) The conventional sealing rosette has a structure in which the main body and the plate are in close contact with each other, including the lower surface of the insulating wall formed between the pair of terminal plates of different polarities. Therefore, once condensation occurs or moisture enters the plate, the moisture will enter the contact area between the insulating wall and the plate due to capillary action, causing terminal plates of different polarities to be short-circuited or grounded. There is,
Particularly, there have been problems with recessed ceiling row sets that are directly attached to the ceiling surface where dew condensation or rainwater infiltration is likely to occur.

The present invention has been developed in view of the above-mentioned problems, and even if dew condenses inside the plate part or rainwater enters, capillary phenomenon will occur due to the gap between the plate part and the insulating wall between the terminal plates of different polarities. The present invention provides a sealing rosette that has improved safety by eliminating short circuits between terminal plates of different polarities and by preventing grounding.

[Structure of the invention]

(Means for Solving the Problems) The sealing [1-Z] of the present invention consists of a main body and a plate covering the main body, and has a seal of 1yrFt!
