Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power distribution gutter device that supplies power by connecting a plug to an arbitrary position of a long power distribution gutter, and more specifically, a power distribution gutter body 1 having an inverted U-shaped cross section with an open bottom. A conductor 3 is provided in the opening 2 for inserting the plug, and a conductor 3 is provided facing each other in the left and right directions and continuous in the longitudinal direction, and a cover 4 made of a thin insulator is elastically displaceable.
The base 5 of the conductor 3 is supported by the groove bottom 6 of the opening 2, and the cover piece T extending from the base 5 covers the entire length of the conductor 3, forming a protrusion 16 at the free edge 8ilC of the cover piece 7. to form a locking stepped portion IT, and protrude from the inner surface of the distribution gutter body 1 along the upper and lower sides of the conductor 3 from the conductor 3. Among the protruding edges 9, the protruding tip on the upper surface side of the lower protruding edge A locking step 17 formed on the free end edge 8 of the cover piece T is elastically locked at the part, and a plug is inserted into the pressured part 11 of the cover piece 7 that is pushed in against the elastic force of the cover piece 7. This invention relates to a power distribution gutter device characterized in that it is formed with an inclined relief 12 that tilts upward in a direction.

As shown in FIG. 1a, the conventional power distribution gutter device includes conductors 3', 3', which are continuous in the longitudinal direction and are opposed to each other in an opening 2' for inserting a plug in a main body 1' of the power distribution gutter. Since a cover 4' made of an insulating sheet is simply provided and a gap a is formed between the conductor 3' and the cover 4',
As shown in Figure 1b, a child mischievously uses a spoon 20
There is a drawback that there is a risk that the wire or pin may easily come into contact with the conductor 3'.

The present invention has been made in view of these conventional drawbacks, and its purpose is to provide a distribution gutter device that can prevent spoons, pins, etc. from coming into contact with conductors through simple improvements. It's about doing. Embodiments of the present invention will be described in detail below with reference to the drawings.

The distribution gutter main body 1 is an extrusion molded product of synthetic resin and has an inverted U-shaped cross section, and is formed with an opening 2 for inserting a plug 13 facing downward. The conductor 3 is buried in the opening 2 over its entire length, facing each other, and the surface of the elongated conductor 3 is exposed in the opening 2. The groove bottom 6 of the opening 2 is wide, and a locking recess 15 into which a locking piece 14 provided on the plug 13 side is rotatably engaged is formed on the opening edge of the opening 2 along the entire length of the distribution gutter body 1. It has been formed over a period of time. The width of the locking piece 14 of the plug 13 in the longitudinal direction of the power distribution gutter body 1 is smaller than the width W of the opening 2. The length t of the locking piece 14 is made approximately equal to the width X of the locking groove 15. The cover 4 is made of a thin insulator made of elastically deformable synthetic resin such as vinyl chloride resin or polyamide resin. Flange edges 18 are formed along the entire length on both sides of the base 5 of the cover 4, and cover pieces 7 extend downward and outward from the base 5. The cover piece 7 is bent in a substantially 〈 shape, and the tip thereof becomes a free edge 8. A protrusion 16 is formed on the free edge 8 to form a locking step 17. As shown in FIG. 2, the base 5 and flange 18 of the cover 4 are brought into contact with the groove bottom 6 of the distribution gutter body 1, and the locking step 17 of the free edge 8 of the cover piece 7 is connected to the conductor. The electrical conductor 3 is covered over its entire length by a cover piece 7, which is in elastic contact with a protruding edge 9 extending below the inner surface 10 of the distribution gutter body 1. In this case, the outer surface of the lower portion of the cover piece 7 is formed with an inclined relief surface 12 that is inclined outward toward the bottom. According to such a configuration, the plug 13
The locking pieces 14, 14 are inserted into the opening edge of the opening 2 of the distribution gutter main body 1, the plug 13 is pushed into the opening 2, and the pressed part 11 of the cover piece 7 is pressed to make the cover piece 7 elastic. After that, the plug 13 is rotated about 907 times to bring the terminal fittings 19 of the plug 13 into contact with the conductor 3, and the locking pieces 14 are locked in the locking grooves 15, so that the plug 13 is attached to the distribution gutter body. It can be electrically connected and attached at any position in the length direction of the piece. In such a case, Figure 5A
, b, even if the spoon 20, pin, etc. are inserted into the opening 2 of the distribution gutter body 1 by mistake, the spoon 20 will slide and escape due to the inclined escape surface 12 formed on the cover piece 7. The spoon 20 and the like cannot easily come into contact with the conductor 3. Moreover, cover piece 7
Even if you try to insert the spoon 20 by pressing the protrusion 16
This prevents the spoon 20 and the like from reaching the conductor 3 because the protrusion 16 is thick and requires force to insert. In summary, the present invention covers a conductor over its entire length with a cover piece extending from the base of a thin insulator cover, and forms a protrusion on the free edge of the cover piece to form a locking step. A lock formed on the free edge of the cover piece at the protruding tip on the upper surface side of the lower protruding edge of the protruding edge formed and protruding from the conductor from the inner surface of the distribution gutter main body along the upper and lower sides of the conductor. Since the step part is elastically locked, it is possible to eliminate the gap between the cover and the conductor, preventing spoons, pins, etc. from easily coming into contact with the conductor. Since an inclined relief surface that is inclined with respect to the plug insertion direction 11C is formed on the pressurized part of the cover piece that is inserted, even if a spoon, pin, etc. are accidentally inserted, the inclined relief surface that is inclined with respect to the insertion direction is formed. By hitting the , you can release snown, pins, etc.
It is possible to avoid pushing the cover piece in, and in this respect, it is also possible to suppress contact with the conductor, making it possible to greatly improve overall safety.
