Description

[Detailed Description of the Invention] The present invention relates to a plug with a switch for a wiring duct, and more specifically, a duct that mechanically and electrically connects the plug body 1 to the wiring duct 16 at the upper end of the plug body 1. The connecting portion 5 is provided protrudingly, and the lower end surface of the plug body 1 is used as an electric appliance mounting surface 6, and the lower end corner of the plug body 1 is chamfered diagonally from the side surface 7 of the plug body 1 to the electric appliance mounting surface 6 to form a chamfered portion. 8, which relates to a plug with a switch for a wiring duct, in which a switching pull string 13 of a pull switch 12 housed inside the plug body 1 is led out from the chamfered portion 8.

In conventional plugs with switches for wiring ducts, the first
As shown in the figure, the electrical appliance mounting surface 6 on the lower end surface of the plug body 1'
Pull switch switching pull cord 13' directly from '
Therefore, when attempting to attach an electrical appliance 17' having a mounting surface 18' larger than the electrical appliance mounting surface 6' of the plug body 1' to the electrical appliance mounting surface 6' as shown in Fig. 2, the switching pull There was a drawback that the string 13' could not be pulled out and could not be used.

The present invention was made in view of the drawbacks of the conventional example,
The purpose of this is to create a mounting surface that is larger than the electrical appliance mounting surface of the plug body by leading out the pull switch switching pull cord from the chamfered part created by diagonally chamfering the bottom corner of the plug body. To provide a plug with a switch for a wiring duct which can be attached to an electric appliance.

Hereinafter, the present invention will be described in detail according to illustrated embodiments.

The plug body 1 is divided into a synthetic resin case 2 and a cover 3.
It is divided into parts and connected with screws 4.

A T-shaped duct connection part 5 protrudes from the upper surface of the plug body 1, and the lower end surface of the plug body 1 serves as an electrical appliance mounting surface 6. The chamfered portion 8 is formed by diagonally chamfering the surface 6) and the side surface I.

A terminal block 9 is fitted into the case 2, and a pull switch 12 is attached to the back of the terminal block 9.

Further, on the front surface of the terminal block 9, a pair of terminal plates 10a, 1
0b is attached, and an L-shaped plug blade 11a is led out from one terminal plate 10a and attached to the duct connection part 5.

The other terminal plate 10b is connected via a pull switch 12 to another plug blade 11b attached to the duct connection part 5.

The pull switch 12 has a switching pull cord 13 which is led out from the pull switch 12 by the action of a deck wheel (not shown).
The switch is opened and closed alternately by pulling the button.

Then, the cover 3 is removed, the mounting surface 18 of the electrical device 7 (for example, a lighting device) is brought into contact with the lower end surface of the case 2, that is, the electrical device mounting surface 6, and the cord 19 led out from the electrical device 1T is connected to the terminal board. 10a and 10b respectively, attach the cover 3 with screws 4, and then insert the duct connection part 5 into the wiring duct 16 to mechanically and electrically connect the wiring duct 16 and the plug body 1. .

The electrical appliance 17 is opened and closed by pulling the switching drawstring 13 and turning the pull switch 12 on and off.

As mentioned above, the present invention has the lower end corner of the plug body diagonally chamfered from the lower end surface of the plug body, which is the electrical appliance mounting surface, to the side surface of the plug body to form a chamfered part, and the pull switch inside the plug body. Since the switching drawstring is led out from the chamfered part, even if an electrical appliance with a mounting surface larger than the electrical appliance mounting surface of the plug body is directly attached to the electrical appliance mounting surface, the electrical appliance, A gap is secured between the mounting surface of the plug and the chamfered part, and the pull switch can be activated by pulling the switching drawstring. There is an advantage that the mounting surface of the electric appliance can be directly attached to the device mounting surface.
