Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a power supply device used to supply power to a wiring duct.

[Background technology]

In recent years, ceiling wiring in factories has come to be done by connecting wiring ducts. Using a wiring duct is very convenient because the wiring can be easily changed and extended, and electricity can be taken out from any position in the wiring duct.

A power supply device with a rod-shaped feed-in terminal was considered as a device for supplying power to a wiring duct. This power supply device is arranged at the end of the wiring duct, and when the feed-in terminal is inserted into the tubular conductor of the wiring duct, power can be supplied from the feed-in terminal to the tubular conductor.

The feed-in terminal needs to protrude beyond the surface where the end of the wiring duct of the power supply equipment touches.
Since it is rod-shaped, if it protrudes from the main body of the power supply device, it is likely to be dropped at a construction site or hit by tools, etc., resulting in damage such as deformation.

[Purpose of invention]

The object of this invention is to provide a power supply device in which the feed-in terminal is less likely to be damaged.

[Disclosure of invention]

The inventors conducted repeated research to achieve the above objectives. As a result, they discovered that the feed-in terminal could be protected by surrounding it with the main body case, and this idea was hereby completed.

Therefore, this invention is a device that is placed at the end of a wiring duct and supplies power, and the front side of the main body case is provided with an opening into which the tubular conductor of the wiring duct can be inserted. The gist of the power supply device is that the tip of the rod-shaped feed-in terminal is inserted further into the front surface of the main body, and almost the entire circumference of the feed-in terminal is surrounded by the main body case. Hereinafter, this invention will be explained in detail based on drawings showing embodiments.

As shown in FIGS. 1 and 3, the power supply device 1 according to this invention has a case 2 consisting of a base 2a and a cover 2b that covers the space below the base 2a. An opening 2c into which the end of the duct 3 is inserted is provided on the front surface of the case 2, and a terminal block 4 is provided on the lower surface of the base 2a. A rod-shaped feed-in terminal 5 is provided on the front surface of the terminal block 4. The feed-in terminal 5 is connected to the opening 2c of the case 2.
The tip of the feed-in terminal 5 is located inside the front surface 6 of the case (main body) 2, and the feed-in terminal 5 is surrounded by the case 2 with a certain gap. It's getting old. As shown in FIG. 1, the opening 2c of the case 2 has two small notches on the left and right sides of the upper surface, and the feed-in terminal 5 is not surrounded by the case 2 in these parts. However, if the cutout is as small as this, there is little chance of a tool or other object getting into it, so there is no problem. That is, in this invention, although it is necessary to surround the feed-in terminal 5 in all directions from top to bottom and left and right to prevent other objects from colliding with the feed-in terminal 5, the feed-in terminal 5 cannot be sufficiently protected. If so, there is no problem even if there are parts that are not enclosed by case 2. As a result of the above-described configuration, there is less risk of a tool hitting the feed-in terminal, and there is less risk of force being applied directly to the feed-in terminal if the power supply device is dropped. Therefore, the feed-in terminal is less susceptible to damage such as deformation.

A protrusion 4a is provided at the lower end of the front surface of the terminal block 4, and a duct 3 is provided on both sides of the protrusion 4a.
A plate-shaped plug blade 7 used for supplying electric power is arranged. This plug blade 7 is not necessarily required. Cords 8a and 8b for supplying electricity to the feed-in terminal 5 and the plug blade 7 are inserted from the rear of the base 2a.

As shown in FIGS. 1 to 3, the wiring duct 3 has a long cover 9 with a C-shaped cross section and an opening 9a facing downward. A tubular conductor 10 and a plate-shaped conductor 11 extending along the length direction of the conductor 9 are fixed respectively. Conductor 11 is not necessarily required. When the end of the wiring duct 3 is inserted through the opening 2c of the case 2 and the feed-in terminal 5 is inserted into the conductor 10, the feed-in terminal 5 and the conductor 10 are electrically and mechanically connected. At this time, the tip of the plug blade 7 comes into contact with the conductor 11, so that both are electrically connected. Then, power can be supplied to the wiring duct 3 from the feed-in terminal 5 and the plug blade 7.

In the embodiment described above, almost the entire circumference of the tip of the feed-in terminal is covered by the front end of the case 2, but this need not necessarily be the case. In short, it is sufficient that the tip of the feed-in terminal enters deeper than the frontmost surface of the main body, and that almost the entire circumference of the feed-in terminal 5 is surrounded by the case 2. Although the power supply device of the above embodiment is connected to a wiring duct only on one side, feed-in terminals are arranged on both sides of the main body and extend deeper than each end face, and the wiring ducts are connected to each side, that is, In some cases, the power supply device is located in the center of the wiring duct.

[Effect of idea]

The power supply device according to this invention is a device that is placed at the end of a wiring duct to supply power, and is equipped with a rod-shaped feed-in terminal that is inserted into the tubular conductor of the wiring duct. It is deeper in than the front, and almost the entire circumference of the feed-in terminal is surrounded and protected by the main body case, so there is less risk of damage to the feed-in terminal.
