Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outlet for a baseboard wiring duct installed on a wall near the floor.

Conventionally, as shown in Fig. 1, an outlet for a baseboard wiring duct installed on a wall near the floor and having a baseboard-like appearance has an outlet plug placed at an appropriate position in a groove-shaped opening 2 drilled in the front surface of the wiring duct 1. It was designed to be formed by attaching a 5'.

However, in the conventional example, when the outlet plug 5' is attached to the wiring duct 1, the blade 9a of the parallel blade plug 8 provided on the front surface of the outlet plug 5'
, 9b, the longitudinal direction of the square insertion holes 10a, 10b is perpendicular to the longitudinal direction of the wiring duct 1. Therefore, when the parallel blade plug 8 is stepped on, there is a problem that the parallel blade plug 8 easily comes out as shown by the imaginary line in FIG. There was a problem in that there was a risk of electric shock if one touched the exposed plug blades 9a, 9b. The present invention aims to solve the above problems. Examples will be described below using figures.

Figures 3 to 5 show an embodiment of the present invention, in which 1 is a wiring duct that is horizontally arranged on a wall near the floor and has a baseboard-like outer shape. Conductor bars 3a and 3b for power feeding are arranged, and the upper conductor bar 3a is the ground side of the commercial power source. A groove-shaped opening 2 is bored in the front surface of the wiring duct 1 over the entire length in the longitudinal direction, and a closure cover 4 is fitted into the groove-shaped opening 2. 5 is an outlet plug, and a housing 6 of the outlet plug 5
L-shaped hook blades Ta and Tb are protruded from the rear surface, and the front surface of the housing 6 has a pair of square holes 10a into which the parallel blade plug blades 9a and 9b are inserted. , 10b are drilled.

On the other hand, inside the housing 6, there are plug blade holders (
(not shown) is provided. This outlet plug 5
Connect the hook blades 7a, 7b to the conductor rods 3a, 3b in the wiring duct 1 by inserting the hook blades 7a, 7b into the groove-shaped opening 2 of the wiring duct 1 and rotating them approximately 90 degrees in a vertical plane. When the plug plug 5 is installed in the wiring duct 1, the double-sided hole 10 is installed.
Square holes 10a, 10b are formed so that the longitudinal direction (arrow A) of a, 10b substantially coincides with the longitudinal direction (arrow B) of the wiring duct 1.
is formed. However, the hook blade and the blade holder to be connected may be formed by bending a single punched metal plate.
Reference numeral 11 denotes a reverse insertion prevention protrusion provided on the front surface of the wiring duct 1, and an arc-shaped (-4 yen) recessed step 12 that can freely engage with this protrusion 11 is formed on the rear surface of the outlet plug 5. , the outlet plug 5 is formed by the protrusion 11 and the recessed step 12.
A reverse insertion prevention mechanism is configured.

That is, when attempting to attach the outlet plug 5 with the square hole 10a into which the wide blade 9a of the parallel blade plug 8 is inserted to the right side, the hook blade 7a of the outlet plug 5,
Even if the outlet plug 7b can be inserted into the groove-shaped opening 2 of the wiring duct 1, the protrusion 11 prevents the outlet plug 5 from rotating. On the other hand, square hole 10
With a side on the left side, hook blades 7a, 7 of the outlet plug 5
b into the groove-shaped opening 2 of the wiring duct 1, and turn clockwise (arrow C
) by rotating the outlet plug 5
The hook blades 7a, 7b and the conductor rods 3a, 3b are connected, and in this case, the square hole 10a facing the blade holder connected to the ground side of the commercial power supply is connected to the other square hole 10b. It will be installed so that it is located above the other hand. Since the concave stepped portion 12 is 7 yen, rotation of the outlet plug 5 to the left is prevented, and the outlet plug 5 is not installed with the square hole 10a facing downward.
Reference numeral 13 denotes a stopper made of a sliding plate that is slidably disposed on the side surface of the housing 6, and the tip of the stopper 13 is made to protrude from the rear surface of the outlet plug 5 to open the groove-shaped opening of the wiring duct 1. By fitting into the outlet plug 5, the outlet plug 5 is prevented from rotating and coming off.

In the figure, 14 is a conductor rod holding rib, 16 is an outlet plug 5
These are two L-shaped engagement pieces protruding from the rear surface of the wiring duct 1 , and the engagement pieces 16 engage with the engagement grooves 17 of the wiring duct 1 . The operation of the embodiment will be explained below.

Now, as shown in FIG. 6, the parallel blade plug 8 attached to the outlet plug 5 is stepped on, and the
Even when the force shown by arrow D) is applied, the parallel blade plug 8 remains in the width direction of the blade 9a (i.e., square holes 10a, 10b).
(longitudinal direction) Since it is installed so as to match the longitudinal direction of the wiring duct 1, it will not easily come off. on the other hand,
As shown in FIG. 7, when a horizontal force (in the direction of arrow E) is applied to the parallel blade plug 8 and the blades 9a, 9b are about to come off, and a portion of the blades 9a, 9b is exposed. Even in this case, the upper plug blade 9a is connected to the ground side of the commercial power supply, and the plug blade 9b, which is a live part, is kept in a state where it is shielded by the ground side plug blade 9a. This means there is less risk of electric shock. The present invention is configured as described above, and by inserting the hooking blade of the outlet plug into the groove-shaped opening of the wiring duct and rotating it approximately 90 degrees in a vertical plane, the hooking blade is inserted into the wiring duct. It is attached so that it is connected to the conductor rod for commercial power supply, and the outlet plug can be attached or detached at will, which has the advantage of making it easy to add outlet plugs or move it to another room. Also, with the outlet plug installed in the wiring duct, the length of the square hole into which the blade of the parallel blade plug is inserted is approximately the same as the length of the horizontally arranged wiring duct. The hole is formed and the parallel blade plug is connected to the outlet plug with the width direction of the blade horizontal, so if the parallel blade plug is stepped on, vertical force will be generated. It has the advantage that the connection does not easily come off even if the plug is inserted, and by providing a mechanism to prevent the outlet plug from being inserted in the opposite direction, the plug blade holder faces the square hole into which the wide plug blade of the parallel plug blade is inserted. The ground side of the commercial power supply is connected to the ground side, and this ground side plug blade holder is positioned above the other plug blade holders, so a horizontal force is applied to the parallel plug blades, causing the parallel plug blades to Even if the plug is unplugged or a part of the blade is exposed, the blade connected to the live part of the commercial power source will remain protected by the blade connected to the ground side. This has the advantage of reducing the risk of electric shock.
