Description

[Detailed Description of the Invention] This invention relates to a wiring duct that can be installed exposed indoors and used to supply power to loads such as lighting equipment and vacuum cleaners from any location.

Conventionally, as shown in FIGS. 1 and 2, this type of duct is formed by installing a conductive wire opening inside both side walls A of a groove body formed in a U-shape in cross section with exposed conductive wire openings, as shown in FIGS. 1 and 2. After attaching this duct 8 to the ceiling X, which is out of reach of people, with screws 2, insert the connector E into the groove of the duct as shown in Figure 1, and by twisting it approximately 90 degrees, connect the connector Plate 8 contacts the conductive wire port and supplies power from duct 8 to the load.

However, since this wire is passed through a groove and the conductive wire opening is exposed to the outside, there is a risk of an electric shock if a child accidentally touches it with a finger or a pinch. For example, it is not possible to install it on an easy-to-use construction surface such as a floor or wall, and it is also impossible to install it on a construction surface that is easy to use, such as a floor or wall, and dust can enter the duct by passing it through the groove, causing a short circuit between the conductive wire ports. Sometimes.

This idea was made focusing on the above circumstances,
Its purpose is to allow wiring to be installed on easy-to-reach construction surfaces such as floors and walls, and to prevent short circuits between conductive wires due to dust entering the inside of the duct through the grooves. Located in providing ducts.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

1 is a duct, and the bottom surface 2 of the groove body is formed into a U-shaped cross section.
One side of the conductive wire 4 is exposed to the inside 6 and attached to both side walls 3 extending from the inside 6 by insert molding, and a corresponding protruding wall 5 is provided at the end 3a of both the side walls 3 so as to be more open than the inside 6. The portion 7 forms a small T-shaped groove 8.

A locking piece 9 prevents the conductive wire 4 from detaching from the side wall 3.

Similarly, the duct 1 may be formed of metal, with only the portion to which the conductive wire 4 is attached made of synthetic resin having insulation properties.

10 is a cover which, when fitted into the groove 8,
a lid 12 that forms a step 11 that abuts the inner surface of the groove 8 and closes the opening 7 of the groove 8; For example, the foot body 13 formed in the shape of a wall that elastically abuts on the
It is integrally formed by plastic molding of elastic synthetic resin such as rubber or vinyl chloride.

This cover 10 can be inserted into the interior 6 of the duct 1 by simply pushing it directly into the groove 8 without inserting it from the end face of the duct 1, so that the legs 13 are flexible.

As shown in Fig. 3, after being attached to an accessible construction surface Y such as a floor or wall surface with screws 14, a terminal plate 15 is provided to contact the conductive wire 4, and a connection is made to supply power to the load. vessel 16
By pushing in the N direction, as shown in Figure 4a,
The foot body 13 of the cover 10 is shortened to form a recess Z in the cover 10, the conductive wire 4 is exposed, and the terminal plate 15 of the connector 16 is inserted into the groove 8.
and inserted into the interior 6 of the duct 1 through the duct 1.

Then, by twisting approximately 90 degrees in the N direction, the terminal plate 15
contacts the conductive wire 4, the terminal plate 15 locks with the locking piece 9, and the protrusion 17 locks with the protruding wall 5 to connect the connector 16.
(/'i It is connected and held to duct 1 and supplies power to the load.

Thereafter, by twisting the connector 16 in the N direction opposite to the N direction, the connector 16 is removed from the duct 1, and the cover 10 is expanded by the elastic force of the leg 13 as shown in FIG. The opening 7 of the groove 8 is closed by bringing the portion 11 into contact with the protruding wall 5.

The end of the duct 1 is crowned with a cap.

Similarly, by forming a notch in this leg body 13, the elastic force can be arbitrarily varied.

As explained above, this invention has conductive wires 4 on both side walls 3.
is mounted so as to be exposed in the interior 6, and a corresponding protruding wall 5 is provided at the end 3a of the side wall 3 so that the opening 7 is larger than the interior 6.
A duct 1 in which a T-shaped groove 8 with a small diameter is formed, and a protruding wall 5
A lid body 12 that forms a step 11 that comes into contact with the groove 8 and closes the opening 7 of the groove 8, and a foot body 13 that springs against the bottom surface 2 of the duct 1 and brings the step 11 into contact with the protruding wall 5 are made of elastic material. Since the cover 10 is fitted into the groove 8, the opening 7 of the groove 8 is closed by the cover 10, and the conductive wire 4 is not exposed to the outside. In addition, since the cover 10 is in contact with the protruding wall 5 due to the elastic force of the foot 13, it is possible to prevent children from accidentally touching the conductive wire 4 with their fingers or pins, so it is not recommended to use the cover 10 on the floor or wall. A wiring duct can be obtained which can be attached to a construction surface Y that is easily accessible, prevents dust from entering into the interior 6 of the duct 1 through the groove 8, and prevents conductive wires 4 from being short-circuited.
