Abstract

PURPOSE:To attain wiring with flexibility without being affected by installing location of terminal equipments arranged decentralizingly by constituting the equipment by wiring cables wired in a loop and consisting of multi-core conductors and branching units inserted in series with the wiring cable and taking electric connection to a desired conductor in the multi-core conductors. CONSTITUTION:Any proper conductor of the multi-core conductors 11 is selected by a matrix switch part 21 and connected electrically to a receptacle part 22. Thus, the receptacle part 22 acts like an information receptacle. The several tens of, for example, multi-core conductors 11 are bundled and each of them forms a loop. Wherever lots of terminal equipments TEs are installed or wherever lots of the TEs are newly installed, the cable 1 is able to be used as if it were for its own exclusive use by using the matrix switch part 21 to select a proper conductor 11 to connect the relevant TE via the receptacle part 22 when there is any idle receptacle part 22 or a branching unit 2. Thus, the wiring equipment with excellent flexibility is realized against the transfer or the like of terminal equipments TE.

Description

[Detailed Description of the Invention] [Summary] A wiring cable made of multi-core conductors and wired in a loop, and electrically connected to a desired conductor in the multi-core conductors inserted in series with this distribution cable. Consists of a branch unit,
Flexible wiring can be performed without being affected by the installation locations of distributed terminal devices.

[Industrial Field of Application] The present invention relates to a wiring device, and particularly to a wiring device for wiring signal lines of distributed terminal devices.

With the recent trend toward office automation, 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 by signal lines, a considerable amount of signal lines are laid out on the office floor.

The present invention refers to wiring devices for these signal lines.

[Conventional technology]

2. Description of the Related Art Conventionally, efforts have been made to route signal lines possessed by a large number of terminal devices efficiently and without spoiling the aesthetic appearance. A typical example is an undercarpet type wiring device that is widely applied to the floors of office buildings. This is pre-wiring signal lines for each terminal device under the carpet. This allows signal lines to be laid freely without damaging the aesthetics of the office floor.

[Problem that the invention seeks to solve]

In the above-mentioned undercarpet type wiring device, the degree of freedom in changing the wiring layout is extremely low, and the cost of removing the carpet and rewiring is considerably high. For this reason, there is a problem in that running costs are high in offices that are frequently redecorated.

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

[Means for Solving the Problems] FIG. 1 is a diagram showing the basic configuration of the present invention. In the figure, reference numeral 1 denotes a wiring cable, which is wired in a loop over the entire cable via the vicinity of a plurality of distributed terminal devices TE. The wiring cable l is a multicore conductor 11 (wiring cable l
(partially shown in cross section).

A plurality of branch units 2 are inserted in series into the distribution cable 1. Branch knit 2 is matrix switch section 21
and an outlet section 22, into which the signal line S of the corresponding terminal device TE is inserted.

[For production]

A suitable conductor of the multicore conductor 11 is selected by the matrix switch section 21 and electrically connected to the outlet section 22. Therefore, the outlet section 22 functions as a so-called information outlet. For example, several ten multicore conductive wires 11 are bundled, each forming a loop.

No matter where the terminal equipment TE is relocated, and if there is space in the outlet section 22 or branch unit 2, the TE
No matter where the matrix switch section 21 is newly installed,
Select a suitable conductor 11 and connect it to the outlet section 22.
By connecting the TE, you can use the cable l anywhere as if it were for your own use.

In this way, a wiring device is realized which is extremely flexible with respect to relocation of the terminal equipment TE, etc.

〔Example〕

FIG. 2 is a diagram showing an example of the overall configuration of the wiring device according to the present invention. Note that similar components are designated with the same reference numbers or signals throughout the drawings.

The wiring device configured by being arranged in advance on the floor of a building, etc., consists of eight branch units 2 and a wiring cable l connected to the FS in the figure. FS is an example of external equipment, and is a floor station run. The floor station run is usually a private branch exchange. Various terminal devices (TE in FIG. 1) are arranged along the distribution cable 1 and branch unit 2 that have been arranged in advance. As various terminal devices, a data terminal DTE and a digital telephone device are illustrated in FIG. These DTEs select the outlet section 21 of the branch unit 2 that is closest to them, and
Select some wiring that is convenient for you, that is, some of the multicore conductors 11, and realize the desired information exchange.

For example, DTE 31 selects conductor 32 and connects it as an extension line to the private branch exchange. Place 33 is also conductor 3
4 and connect it to the private branch exchange as an extension line. Further, the DTEs 35, 36, and 37 commonly select the conducting wire 38 to exchange data between them. Further, terminals 41 and 43 select conductors 42 and 44 as extension lines, respectively, and connect them to the private branch exchange. Further, the DTEs 51 , 53 and 55 select conductors 52 , 54 and 56 respectively, and communicate with the host computer 5 via a communication control unit (CCP) 57.
8 and form a network as a whole.

The larger the number of multicore conductors 11, the better, but since there is a physical limit, a predetermined number (for example, 30) is required. Therefore, all terminal devices need to effectively utilize the multicore conductors. For example, in FIG. 2, one loop-shaped conducting wire 11 including the conducting wire 38 has a portion other than the conducting wire 38 connected to the conducting wire 42.
It is desirable to share it as a. The selection of these conducting wires is performed by the matrix switch section 21 of the branching unit 2.

FIG. 3 is a plan view showing a second example of the branching unit. The part indicated by the arrow 21 is the matrix switch part, and the outlet part 22 is combined with this. Outlet part 2
2 is made up of, for example, a modular jack 221, and is connected to a signal line S of a terminal device.

In the illustrated example, the matrix switch section 21 includes two conductor selection matrices 211 and 212, two DIP switches 213 and 214, and two connector sections 215 and 216. The conducting wire selection matrices 211 and 212 respectively correspond to the outgoing path side and the incoming path side of each conducting wire (each conducting wire actually consists of a pair of wires).

In this figure, electrical connections are made at the intersections marked O in the conductor selection matrices 211 and 212, and the corresponding modular jacks 221 can be used.

The connector parts 215 and 216 are detachably connected to the wiring cables 1 laid out on the right side and the left side in the figure, respectively. When the wiring cable l on the left side and the wiring cable 1 on the right side are connected through each other (conductor wire 38 in the branch unit 61 in Fig. 2), when connecting only with the wiring cable l on the left side (in Fig. 2) Conductor 3 in branch unit 62
8), when connecting only to the wiring cable 1 on the right side (2nd
DIP switches 213 and 214 are provided for each conductor, although there are various connection modes such as the conductor wire 38 in the branch unit 63 shown in the figure. DIP switches are commercially available parts that operate by pressing each switch to turn it on, holding it there, and pressing it again to turn it off.

Note that commercially available conductor selection matrices 211 and 212 can be used. For example, with a mini-matrix slide switch manufactured by AMP Japan, a desired slider among a plurality of sliders may be shifted left or right to connect it to a desired conductor. In any case, branching unit 2 is
Since it's placed on the floor (and it's better to put a carpet on top of it), it's best to have a flat surface, and the mini-matrix slide switch mentioned above is suitable for this. On the other hand, since the distribution 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 branching unit. This branch unit 2 constitutes a so-called electronically controlled matrix switch, and for this purpose, it first provides some of the conductors in the wiring cable 1 to the computer (CPU in FIG. 2).
From this, conductor connection information is sent. This is received via the signal transmission/reception section 219 in FIG. 4, decoded by the control section 218, and then the analog IC matrix 217 is controlled. This analog IC matrix 217 consists of semiconductor switches that connect each conductor to the modular jack 221 in correspondence with each conductor, and provides on/off control information to its control gate to form or open an electrical connection.

FIG. 5 is a schematic diagram showing an example of the application of the wiring device according to the present invention, for example, five tenant companies (A, B).

An example is shown where C, D and E) are on the same floor. However, only Tenant A will be depicted and shown in a concrete image. FS is the floor station described above, and is connected to each loop-shaped distribution cable 1 via the connection switching switching system FSS.

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

〔Effect of the invention〕

As explained above, according to the present invention, even if terminal equipment is relocated or newly installed, even if the terminal equipment is pre-wired (wired in advance), the terminal equipment can be connected to each other or to external equipment simply by operating the matrix switch. can be completed easily and in a short time.
