Description

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

[Background technology]

Recently, ceiling wiring in factories has been 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 placed at the end of the wiring duct,
The feed-in terminal constitutes a power distribution device together with the wiring duct, and when the feed-in terminal is inserted into the tubular conductor of the wiring duct, power can be supplied to the tubular conductor from the feed-in terminal.

However, if a feed-in terminal is inserted into a tubular conductor to make a mechanical connection between the wiring duct and the power supply device, the power supply device is usually not fixed by anything other than the feed-in terminal, so if force is applied to the feed-in terminal, , the feed-in terminal tends to separate from the tubular conductor, making the electrical connection unstable. Furthermore, when connecting, it is difficult to align the tip of the feed-in terminal with the opening of the tubular conductor.

[Purpose of invention]

The object of this invention is to provide a power distribution device in which a feed-in terminal can be easily inserted and the electrical connection strength between a wiring duct and a power supply device is high.

[Disclosure of invention]

In order to achieve the above objectives, the inventors conducted repeated research. As a result, they discovered that it is sufficient to provide a guide at the connection between the power supply device and the wiring duct to position the connection between the two.
This idea was completed here.

Therefore, this invention provides a power distribution device that includes a wiring duct and a power feeding device disposed at the end of the wiring duct, in which at the connecting portion of the power feeding device and the wiring duct, a wire is provided in front of each other in the longitudinal direction. The power feeding device is provided with a guide plate that protrudes from the front outer periphery toward the power distribution duct, and the power distribution duct has a guide plate that extends along the length from the front end of the outer peripheral surface. , the gist thereof is a power distribution device characterized in that a guide groove is provided with which the guide plate is engaged. Hereinafter, this invention will be explained in detail based on drawings showing embodiments.

As shown in FIGS. 1 to 3, the power supply device 1 of the power distribution device 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 is provided in the front of the case 2 into which the end of the duct 3 is inserted, and holes are provided at the upper and lower ends of the opening 2c for positioning the connection between the two when connecting the power supply device to the wiring duct 3. Guide plates 2d and 2e that serve as guides are provided in a protruding manner. The tip of the guide plate 2e is bent upward to form a bent portion 6. base 2
A terminal block 4 is provided on the bottom surface of a, and a rod-shaped feed-in terminal 5 is provided on the front surface of the terminal block 4. A protrusion 4 is provided at the lower end of the front surface of the terminal block 4.
A is provided, and plate-shaped plug blades 7 used for supplying power to the duct 3 are arranged on both sides of the protrusion 4a. 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.

The wiring duct 3 has a long cover 9 having a C-shaped cross section and an opening 9a facing downward. A groove 9b is provided on the upper surface of the cover 9. A tubular conductor 10 and a plate-shaped conductor 11 extending along the length of the cover 9 are fixed to the upper and lower parts of the cover 9, respectively. Conductor 11 is not necessarily required.

The wiring duct 3 and the power supply device 1 are connected as follows. First, the guide plate 2d is aligned with the front end of the groove 9b, and the bent piece 6 of the guide plate 2e is aligned with the opening 9a. next,
The power supply device 1 is pressed toward the wiring duct 3, the guide plate 2e is slid along the groove 9b, and the bent piece 6 is advanced along the opening 9a. Then, the feed-in terminal 5 is inserted into the conductor 10, and the two are electrically and mechanically connected, and the tip of the plug blade 7 comes into contact with the conductor 11, so that the two are also electrically connected. Then, power can be supplied to the wiring duct from the feed-in terminal 5 and the plug blade 7. That is,
Feed-in terminal 5 and plug blade 7 of power supply device 1 and tubular conductor 10 and plate-shaped conductor 11 of wiring duct 3
serves as a power feeding section for feeding power from the power feeding device 1 to the wiring duct 3.

In the power distribution device according to this invention, the power feeding device 1 is provided with guide plates 2d and 2e, and the wiring duct 3 is provided with a guide groove consisting of a groove 9b and an opening 9a, which are used to determine the joining position of the power feeding device and the wiring duct. The feed-in terminal 5 and the conductor 10 can be easily connected. Furthermore, when the power supply device 1 and the wiring duct 3 are connected, the protruding pieces 2d and 2e are in a state where the wiring duct 3 is sandwiched between the power supply device 1 and the wiring duct 3.
Even if a force is applied to the conductor 10, the protruding pieces 2d and 2e resist, so that the force that tends to separate the feed-in terminal 5 from the conductor 10 is reduced. Therefore, the power supply device 1
This increases the electrical connection strength of the wiring duct 3.

If the tip of the guide plate is made to protrude beyond the tip of the feed-in terminal, as in the power supply device of the above embodiment, there is less risk of the tool hitting the feed-in terminal, and if the power supply device is dropped, it will not be possible to directly feed the feed-in terminal. There is also less risk of force being applied to the terminals. Therefore, the feed-in terminal is less susceptible to damage such as deformation. The number of installed guides, the installed locations, and the structure are not limited to the examples. For example, guides may be installed on the left and right sides of the power supply device and the wiring duct.
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 power supply device and guides are provided, and a wiring duct is connected to each side. That is, there are cases where the power supply device is located in the center of the wiring duct.

[Effect of idea]

The power distribution device according to this invention includes a wiring duct and a power feeding device disposed at the end of the wiring duct, and a guide for positioning the connection between the two is provided at the connection portion of the power feeding device and the wiring duct. Since the feed-in terminal is provided, it is easy to insert the feed-in terminal, and the electrical connection strength between the wiring duct and the power supply device is high.

In other words, at the connection between the power supply device and the wiring duct,
By simply inserting the guide plate of the power supply device, which is placed on the outer peripheral surface that is easily visible from the outside, along the guide groove of the wiring duct, you can accurately connect the power supply parts such as feed-in terminals and tubular conductors located inside the wiring duct. This makes it possible to connect in a positioned state. This method is much easier to connect than the conventional method, which involves aligning the tips of multiple feed-in terminals and the openings of the tubular conductor one by one in locations that are hard to see on the inside front of the power supply device and wiring duct. This makes the connection easier, and accidents such as accidentally bending the feed-in terminal or tubular conductor during connection become less likely to occur. In addition, the power supply device and the wiring duct are fixed by the mechanically strong bond between the guide plate and the guide groove, so even if an external force is applied with the power supply device and the wiring duct connected, the power supply of the feed-in terminal or tubular conductor, etc. There is no need to worry about parts coming off, electrical connections becoming unstable, or deformation or damage.
