Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A wiring cable made of multi-core conductors and arranged in a loop, and a branch that is inserted in series in the wiring cable and electrically connected to a desired conductor in the multi-core conductors. It is composed of a unit, and flexible wiring can be performed without being affected by the installation locations of the terminal devices distributed and arranged.

[Industrial application field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device, and more particularly to a wiring device for wiring signal lines of terminal devices distributed and arranged.

With the recent shift to OA, a large number of various terminal devices have been introduced into office buildings and the like. Since these terminal devices are connected to each other or to external terminal devices and the like by signal lines, a considerable amount of signal lines are laid on the office floor.

The present invention refers to a wiring device for these signal lines.

[Conventional technology]

Conventionally, a device for efficiently wiring the signal lines of a large number of terminal devices without impairing the aesthetic appearance has been made. A typical example thereof is an undercarpet type wiring device that is widely applied to the floors of office buildings. This is a signal wire pre-wired under the carpet for each terminal device. As a result, the signal line can be freely laid without impairing the appearance of the office floor.

[Problems to be solved by the invention]

In the undercarpet type wiring device, the flexibility of wiring layout change is extremely low, and the cost is considerably increased by removing the carpet and rewiring. For this reason, there is a problem that the running cost is high in an office where pattern changes are frequent.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wiring device capable of handling terminal equipment relocation and new installation extremely flexibly.

[Means for solving problems]

FIG. 1 is a diagram showing the principle configuration of the present invention. In the figure, reference numeral 1 denotes a wiring cable, which is laid in a loop shape on a wire body via the vicinity of a plurality of terminal devices TE which are distributed. The wiring cable 1 is a multi-core conductor 11 (wiring cable 1
Is shown in cross section).

In the wiring cable 1, a plurality of branch units 2 are inserted in series. The branch unit 2 is a matrix switch unit 21.
And the outlet section 22, and the signal line S of the corresponding terminal device TE is inserted into the outlet section 22.

[Operation] One of the appropriate conductors of the multi-conductor conductor 11 is selected by the matrix switch portion 21 and electrically connected to the outlet portion 22. Therefore, the outlet section 22 functions as a so-called information outlet. For example, several tens of multi-conductor wires 11 are bundled, and each of them forms a loop.

Wherever the terminal equipment TE is relocated, and if the outlet 22 or the branch unit 2 is available, the TE
No matter where the new switch is installed, the matrix switch section 21
Select an appropriate conductor 11 with, and through the outlet 22
If the TEs are connected together, the cable 1 can be used as if it were for exclusive use everywhere.

Thus, a wiring device that is extremely flexible with respect to the relocation of the terminal equipment TE is realized.

〔Example〕

FIG. 2 is a diagram showing an example of the overall configuration of the wiring device according to the present invention. Note that the same reference numerals or symbols are given to the same components throughout the drawings. The wiring device, which is preliminarily arranged on the floor such as a building floor, includes eight branch units 2 and a wiring cable 1 connected to the FS in the figure. The FS is an example of an external device, which is a floor station. The floor station is usually a private branch exchange, and along with a wiring cable 1 and a branching unit 2 arranged in advance, various terminal devices (T in FIG. 1).
E) is placed. As various terminal equipment, a data terminal DTE and a digital telephone TEL are illustrated in FIG. These DTEs and TELs select the outlet section 21 of the branching unit 2 close to them and select some of the wirings convenient to them, that is, some of the multi-core conductors 11 to realize the intended information exchange.

For example, DTE 31 selects conductor 32 and connects it to the private branch exchange as an extension line. The TEL 33 also selects the lead wire 34 and connects it to the private branch exchange as an extension line. Further, the DTEs 35, 36 and 37 commonly select the conductor 38 to exchange data with each other. In addition, TEL 41 and 43 are conductors 42 and 44 as extension lines, respectively.
Select and connect to the private branch exchange. In addition, DTE 51,53
And 55 select conductors 52, 54 and 56, respectively, and exchange data with a host computer 58 via a communication control unit (CCP) 57 to form a network as a whole.

The larger the number of the multi-conductor wires 11, the better. However, since there is a physical limit, the number is set to a predetermined number (for example, 30). Therefore, it is necessary for all terminal devices to effectively utilize the multi-conductor wire. For example, in FIG. 2, one loop-shaped conductor 11 including the conductor 38 has a portion other than the conductor 38 in the conductor 42.
It is desirable to share as. The matrix switch unit 21 of the branching unit 2 selects these conducting wires.

FIG. 3 is a plan view showing a first example of the branch unit. The portion indicated by the arrow 21 is a matrix switch portion, to which the outlet 22 is integrated. The outlet 22 is composed of, for example, a modular jack 221, and is connected to the signal line S of the terminal device. In the illustrated example, the matrix switch section 21 includes two dip switches 213 and 214 and two connector sections 215 and 216 in addition to the two conductor selection matrices 211 and 212. Conductor selection matrix
Reference numerals 211 and 212 respectively correspond to the forward path side and the return path side of each conductor (each conductor is actually a pair of wires). In this figure, electrical connection is made at the intersections marked with a circle in the conductor selection matrices 211 and 212, and the corresponding modular jacks 221 can be used.

The connector portions 215 and 216 are detachably connected to the wiring cable 1 laid on the right side and the left side in the drawing, respectively. This left wiring cable 1 and right wiring cable 1
And when they are connected through each other (conductor 38 in branch unit 61 in FIG. 2), when connected only to wiring cable 1 on the left (conductor 38 in branch unit 62 in FIG. 2), wiring on the right When connecting only to the cable 1 (conductor 38 in the branching unit 63 in FIG. 2) and the like, there are various types, but dip switches 213 and 214 are provided in order to correspond to these conductors for each conductor. Dip switches are commercially available parts, and they move by pressing each switch to turn it on and holding it, and then pressing the switch again to turn it off.

As the conductor selection matrices 211 and 212, commercially available ones can be used. For example, a mini-matrix slide switch manufactured by Japan AMP Co., Ltd. A desired one of a plurality of sliders may be shifted to the left and right to be connected to one desired conducting wire. In any case, since the branch unit 2 is placed on the floor (it is better to lay a carpet on it), the flat unit is good, and the mini-matrix slide switch described above is suitable for this. On the other hand, since the wiring cable 1 is also placed under the carpet, it is preferable to use a flat cable.

FIG. 4 is a plan view showing a second example of the branch unit. The branching unit 2 forms a so-called electronically controlled matrix switch, and for that purpose, first, a part of the conductors in the wiring cable 1 is provided to a computer (CPU in FIG. 2), and the conductor connection information is transmitted from the computer. This is received via the signal transmission unit 219 of FIG. 4, decoded by the control unit 218, and then the analog IC matrix 217 is controlled. This analog IC
The matrix 217 is made up of semiconductor switches that connect the respective conductors to the modular jack 221 corresponding to the respective conductors, and supplies ON / OFF control information to its control gate to form or open an electrical connection.

FIG. 5 is a schematic diagram showing an application example of the wiring device according to the present invention, and shows an example in which five tenant companies (A, B, C, D and E) are on the same floor. However, only tenant A is shown with a concrete image. FS is a floor station described above, and is connected to each loop-shaped wiring cable 1 via a switching system FSS for connection change.

FIG. 6 is a view showing a modified example of the wiring device according to the present invention, in which the bypass loop 71 and the sub-loop 72 are arranged in advance to further increase the flexibility of wiring. For this purpose, a special branch unit, namely the loop changing unit 2 ', is introduced. However, the structure of the loop changing unit 2'is also the same as that of the branching unit 2 shown in FIG. 3 or 4 in principle. The only difference is that the outlet section 22 of the branch unit 2 is replaced with the connector section (215, 216) and that the numbers of orthogonal conducting wires of the matrix switch are equal to each other.

〔The invention's effect〕

As described above, according to the present invention, even if the terminal device is moved or newly installed while pre-wiring (preliminary wiring is completed), it is possible to operate the terminal device mutually or externally by simply operating the matrix switch. Connection can be completed easily and in a short time.
