Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This is a technology that can provide a means to economically and quickly conduct AC electrical wiring for one room when constructing a room in a condominium or an office in a building.

[Conventional technology]

A plastic outer casing is fixed to the back of the ceiling of the club room.
A load power supply device having a plurality of vinyl cables having one end fixed to an outer casing and the other end electrically connected to an AC power source, a load lamp, a wall switch, a ground terminal, etc. is well known.

At the factory, the vinyl cables connecting the outer casing and the load are constructed into one unit, and this is transported to the site to quickly complete the electrical wiring work, making it an effective technology that has found a wide range of applications.

c Problems to be solved by the present invention] The number of insulated conductors included in the vinyl cable introduced into the outer casing is 3 to 3.
Since there will be zero connections, the process of electrically connecting each terminal within the foreign company will be complicated. Therefore, there arises an inconvenience that the chance of erroneous connection increases.

The first problem is the complexity of the process described above and the resulting erroneous connections.

There is a second problem in that the above-mentioned connections make it difficult to introduce automatic machines.

Furthermore, if the outer casing can be made flat, it will have a shape suitable for installation on a ceiling. However, due to the above-mentioned circumstances, there is a third problem in that it cannot be constructed flatly.

[Means for solving problems]

A copper plate of a predetermined shape is made by press working on a disc-shaped plastic plate shown in Figure 2 (α), (h), and (C) of this Civilization Specification, and is placed and fixed, and the plastic plate is overlapped and fixed. However, the terminals of the insulated conductive wires included in the vinyl cable are electrically connected to the outer conductor terminal plate by means such as electric welding or soldering.

Therefore, the first and second problems can be solved by attaching symbols to the conductor terminal board and the vinyl cable in advance and connecting them with the same symbol. Also, automatic machines can be introduced and used for this purpose.

Also, the thickness of the plastic flat plate is about λ mm, so
Even if three or more layers are stacked, the height of the outer casing will be about 10 millimeters. Therefore, the third problem is solved.

[Effect]

At the factory, we can perform the necessary electrical connections of the vinyl cable inside the outer casing, as well as cut the vinyl cable to the length up to the load and expose the terminal conductor, making the work more reliable. The frequency of failures becomes extremely low. On-site, all you have to do is install the outer casing on the ceiling and connect the end of the vinyl cable to the load.
You can finish the work in a short time.

Since the other end of the vinyl cable Jd is connected to an indoor outlet, for example, an electric washing machine can be operated by inserting a plug into it. Moreover, since one of the vinyl electric wires is electrically connected to the conductor terminal plate 5C, the other end can be used as a ground terminal.

The length of the vinyl cable depends on the location of the outlet and the outer casing.
By positioning A, the length is calculated in advance, and the step of cutting and adjusting the vinyl electric wire can be omitted when wiring indoors. The same method has been adopted for other vinyl cables.
