It is.

As described above, in the power supply duct system of the present embodiment, the contact portion between the conductor 7 and the contact 8 is formed between the top surface 10 of the duct main body 3 and the upper surface of the insertion portion 5 of the plug 2. By providing the space between them, the side surface 1 of the conventional duct body 3
1 compared to the distribution duct 1 formed by providing the conductor 7 (see FIG. 18),
The length of the side surface 11 of the duct main body 3 protruding from the top surface 10 can be shortened by reducing the length of the power distribution duct 1 from the top surface 10 because the length of the distribution duct 1 can be reduced. It is. As a result, the space for the power supply duct system can be reduced. For example, the power supply duct system can also be used in a system rack 42 for storing a personal computer or the like as shown in FIG. It can be deployed and expand the range of applications of the power supply duct system. FIGS. 8 and 9 show an example of a usage form of the present power supply duct system, which includes arranging the wiring duct 1 along a support column 45 of a system rack 42 and extending the wiring duct 1 in the longitudinal direction. 2 shows a state in which a plurality of plugs 2 are arranged at arbitrary positions, and a power plug 44 extended from an electric appliance 43 such as a personal computer housed in a system rack 42 is inserted into the power supply section 16 of the plug 2. I have.

Further, since the convex portion 13 of the duct body 3 and the concave portion 14 of the plug 2 are provided at one of both side ends in the width direction, the contact portion between the duct body 3 and the plug 2 is formed. The shape is an asymmetric shape with respect to the center in the width direction. Distribution duct 1 as described above
When the plug 2 is attached to the
This has a structure in which, if turned over, the plug 2 cannot be mounted on the power distribution duct 1 unless the convex portion 13 is stored in the concave portion 14.
This prevents the plug 2 from being attached in the width direction of the duct main body 3 when the plug 2 is attached to the power distribution duct 1. There is an advantage that mounting is performed without errors.

In the power supply duct system of this embodiment, the work of attaching the plug 2 to the power distribution duct 1 is performed by inserting the insertion portion 5 of the plug 2 into the opening 12 of the duct body 3 in the top direction as described above. The operation is performed only by the operation of inserting the device in a facing direction, and a so-called one-touch mounting structure is employed. This has the advantage that the plug 2 can be attached to the power distribution duct 1 with a simple operation, thereby improving the convenience of the mounting, and the case where a plurality of plugs 2 are mounted adjacent to the power distribution duct 1. In some cases, the plug 2 can be attached without forming a dead space.

The advantages of the former will be described in detail.
With respect to the work of attaching the power supply duct to the wiring duct 1, in a conventional power supply duct system having a rotary mounting structure and a power supply duct system having a lever type mounting structure, the duct body 3
The operation of rotating the plug 2 itself and the operation of operating the operation lever 33 are performed after the operation of inserting the insertion portion 5 of the plug 2 into the opening 12 of the first embodiment. In the power supply duct system of the present invention, only the operation of inserting the insertion portion 5 of the plug 2 into the opening 12 of the duct main body 3 is performed, that is, the power supply duct system of this example is a conventional power supply duct system. The work of attaching the plug 2 to the power distribution duct 1 is reduced by one process compared to that of the power supply duct, and in the power supply duct system of the one-touch mounting structure of this example, the work of mounting the plug to the power distribution duct is simplified, and Convenience is improving.

The advantage of the latter will be described in detail. In the power supply duct system having the rotary mounting structure, the plug 2
When the plug 2 is attached to the power distribution duct 1, the plug 2 itself is rotated around the insertion portion 5.
The dimension of the plug 2 with respect to the longitudinal direction of the distribution duct 1 is different between before and after rotation, that is, the plug 2
The space required for the installation work of the power supply duct 1 to the power distribution duct 1, that is, the space in which the plug 2 rotates is the actual plug 2
In some cases, extra space may be required as compared with the space required for installation in the power distribution duct 1. Then, a plurality of plugs 2 are connected to the distribution duct 1
When the plug 2 is mounted adjacent to the power distribution duct 1, the extra space required for mounting the plug 2 to the power distribution duct 1 becomes a dead space compared to the actual space for mounting the plug 2 to the power distribution duct 1. Plug 2 adjacent
It will remain in between. On the other hand, in the power supply duct system of the one-touch mounting structure of the present embodiment, the plug 2 can be mounted on the power distribution duct 1 simply by inserting the plug 2 into the opening 12 of the duct body in the direction of the top surface. The space required for mounting the plug 2 to the power distribution duct 1 is only the space for mounting the actual plug 2 to the power distribution duct 1, that is, a plurality of plugs 2
Is installed adjacent to the power distribution duct 1, the dead space cannot be formed between the adjacent plugs 2.

Furthermore, in the power supply duct system of the present embodiment, the plug 2 is attached to the power distribution duct 1 because the contact 8 on the upper surface of the plug 2 is brought into contact with the conductor 7 on the top surface 10 of the duct body 3. When the opening 12 of the duct body 3 is
There is an advantage that the conductor 7 can be viewed from the outside, so that the plug 2 can be securely attached to the power distribution duct 1, and frictional powder generated between the conductor 7 and the contact 8 is removed from the opening 12 of the duct body 3. And the frictional powder can be prevented from staying in the duct main body 3 and the occurrence of a short circuit between the plug 2 and the power distribution duct 1 caused by the frictional powder can be reduced. There is also the advantage that you can.

In the conductor 7 and the contact 8, if one of the three conductors 7 arranged side by side at one end in the width direction of the top surface 10 which is the juxtaposed direction is used for grounding, the basic design is By changing only the configuration (usage form) of the conductor 7 without changing it, it is possible to easily configure the power supply duct system according to various outlet standards (for example, country-specific standards). Therefore, there is an advantage that the versatility of the power supply duct system can be improved.

If the center conductor among the three conductors 7 arranged side by side is used for grounding, which is contrary to the example of the present embodiment, the convex portion 13 of the duct body 3 and the concave shape of the plug 2 are formed. In the case where the shape of the contact portion between the duct body 3 and the plug 2 is formed symmetrically with respect to the center in the width direction without providing the portion 14, when the plug 2 is attached to the power distribution duct 1, Since the ground is always located at the center in the width direction even if the direction of the plug 2 is mounted in the width direction of the duct main body 3, the degree of freedom in mounting the plug 2 to the power distribution duct 1 is improved and the convenience is improved. There is an advantage that is improved. this is,
Contact 8 of plug 2 for making electrical contact and distribution duct 1
This is effective when it is not necessary to match the polarity between the conductor 7 and the conductor 7.

The longitudinal end face 1 of the duct body 3
It is also preferable to provide a connecting portion for connecting another duct main body portion 3 to 5. As shown in FIG. 10, the connecting portion forms a longitudinal through hole 34 extending in the longitudinal direction of the duct main body 3 in a portion between the side surface 11 and the top surface 10 of the duct main body 3, A fitting pin 35, which is another member, is inserted and fitted into the opening of the longitudinal through hole 34 on one of the end faces 15 in the longitudinal direction of the fitting pin 35.
Is made to protrude in the longitudinal direction from the longitudinal end face 15 of the duct body 3. A plurality of duct main bodies 3 provided with such connecting portions are arranged in the longitudinal direction, and a tip of a fitting pin 35 protruding from one duct main body 3 is connected to a longitudinal through hole 34 of another adjacent duct main body 3. The plurality of power distribution ducts 1 can be easily connected in the longitudinal direction by being fitted to the power distribution duct 1.
