DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. First, the concept of the basic configuration of the concealing type electric / information outlet of the present invention is schematically shown in FIG. In the basic configuration shown, the power transformer 1 is connected to the
Divided underfloor core 1 _a and floor iron core 1 _b to the primary winding 3
_a and a secondary winding 3 _b are respectively wound, and an information signal transformer 2 is similarly divided into two through a plane gap to form an underfloor magnetic core 2 _a and an above-floor magnetic core 2 _b with a primary coil 4.
_a and the secondary coil 4 _b are wound around each other.

As described above, the underfloor portion and the upper floor portion of the power transformer 1 and the information signal transformer 2 which are each divided into two by the air gap plane are formed integrally with each other by aligning the air gap planes and by plastic molding or the like. Underfloor outlet A and above-floor outlet B
With the void plane almost flush with the floor surface and buried under the floor, the floor outlet B is properly attached to the bottom of the desk, and the marks for clearly indicating the positions of both are attached to the floor for accurate alignment. , underfloor, floor both outlet a, and the B so as to face to place the desk, the core 1a, 1 _b and the magnetic core 2 _a, 2 _b of the underfloor and floor are installed in a state of being shock-joining respectively. If it is necessary for aesthetic reasons, the upper surface of the underfloor outlet should be protected by covering it with a thin reinforced plastic plate.

The concealed type electrical / information outlet of the present invention having such a basic structure is installed under the floor as described above, and the power source transformer 1 and the information signal transformer 2 have a primary winding _3a and a primary coil _4a which are suitable. While it is connected to the outside by under-floor wiring, and the secondary winding 3 _b and the secondary coil 4 _b are connected to electrical / information equipment on the desk, in reality, various electronic information equipment can be installed on the same desk. Since it is installed, the power transformer 1 is a combination of a plurality of rated ones that match the required power of each device, or an appropriately combined large-capacity transformer is provided, and its secondary output is in the floor outlet B. , And the information signal transformer 2 combines a required number of pulse transformers or high frequency transformers of a plurality of standards according to the type of electronic information signal required for each on-board device,
As in the power transformer 1, its secondary side output is branched into a plurality of outputs in the floor outlet B, if necessary.

Furthermore, in practice, in many cases, a large number of desks equipped with a plurality of electronic information processing devices of the same combination or different combinations are arranged in the same office. It is preferable to disperse the concealed type electrical / information outlets of the present invention in which 1 and the information signal transformer 2 have the same configuration or different configurations, respectively, on the floor in accordance with the placement of the desk.

However, since there are various combinations for mounting various kinds of electronic information processing devices on the same desk, the configurations of the electric / information outlets of the present invention corresponding to each combination are also various, and The electric / information outlet of the present invention will also be replaced according to the rearrangement of the desk or the combination of the mounted devices. However, the power supply transformer 1 constituting the electric / information outlet of the present invention is an AC transformer 1 of commercial frequency, although the ratings are different, and the information signal transformer 2 also has a wide variety of information signal contents. However, since the signal format is a pulse signal having an appropriate bit rate or a carrier information signal having an appropriate frequency, the configuration of the transformer is only two to three types.

Therefore, as the underfloor outlet A to be buried under the floor, a plurality of power supply transformers 1 having a plurality of ratings including those having a maximum rating within the practicable range, and a plurality of types of information signal transformers 2 of the maximum number respectively. By constructing a general-purpose underfloor outlet in combination with the above in anticipation of future demand, and disposing such general-purpose underfloor outlets in the room in advance according to the size of the office, the model and number of devices installed on the same desk It is possible to deal with any change of the above and any arrangement of the desk without replacing the underfloor outlet A.

If the general-purpose underfloor outlet A to be buried under the floor is standardized, the on-floor outlet B, which can be easily replaced because it is attached to the desk, can be selectively used for each required portion of the general-purpose underfloor outlet A. The concealed power supply / information outlet of the present invention can be operated efficiently and smoothly by preparing a plurality of types configured so as to be opposed to each other and replacing them whenever necessary.

However, as described above, the power supply / information outlet of the present invention in which a plurality of power supply transformers 1 and information signal transformers 2 are collectively formed has a large number of transformers 1 and transformers 2 on the same plane. Since it will be placed inside, it is necessary to reduce the occupied area as much as possible and try to miniaturize it, but in general, compared with the iron cores 1 _a and 1 _b of the power transformer 1, the iron core 2 of the information signal transformer 2 since _a, 2 _b is much smaller, for example, a top in FIG. 2 (a), as a side in FIG. 2 (b), 2 leg iron core 1 _a of the power transformer 1 comprising a large, 1 _b It is preferable to fit the magnetic cores 2 _a and 2 _b of the small-sized information signal transformer 2 into the inner space with the air gap planes aligned and to combine them. In addition, power transformer 1
Since the operating frequencies of the information signal transformer 2 and the information signal transformer 2 are significantly different from each other, mutual interference is small even when they are fitted and combined with each other, and no trouble occurs.

The above-mentioned general-purpose underfloor outlets are distributed according to the expected placement of desks in the office and are buried under the floor in advance. The underfloor wiring for the distributed general-purpose underfloor outlets is shown in FIG. 3, for example. It is preferable to make it as shown. That is, the wiring of the AC power source for the power transformers 1 _a-1 to 1 _an in each general-purpose underfloor outlet can be all provided in parallel as shown in the figure, but if necessary, it can be properly and individually separated via a switchboard. It can also be intermittent. On the other hand, the wiring of the information signal to the information signal transformers 2 _a-1 to 2 _an is as follows.
_{a-1 to} 2 _an are individually connected to, for example, a control panel provided on the wall surface of an office, and are arbitrarily switched and connected to information signal lines inside and outside the office required for each, for example, a telephone line corresponding to an identification number. It is preferable to obtain it, and even if the desk is rearranged, the underfloor wiring can be handled without any change.

[0015]

As is apparent from the above description, according to the present invention, power supplies for a large variety of electric and information equipments, which are piled up on the desks arranged in the office with the progress of office automation, are provided. Wiring can be secured by simply connecting all the information signal connection wiring to a transformer and matching the desk's placement with the underfloor outlet embedded in the floor so that the on-floor outlet attached to the bottom of the desk closely opposes. Being hidden under the floor, the appearance and safety of the floor are not impaired, and the desk layout can be simplified.
