Description

[Detailed Description of the Invention] [Summary] A wiring device comprising a plurality of information outlets each having a plurality of terminals under its control, and a wiring cable into which these information outlets are inserted in series, the wiring cable forming the wiring device. A branch line is provided to branch from each of the plurality of circuit lines, and a desired line from among these branch lines is selected and connected to each terminal. By providing a type switch and a plurality of mechanically operated type switches for the above selection,
It is a wiring device that is small, inexpensive, and can be connected to any circuit line with a high degree of freedom.

[Industrial application field]

The present invention relates to a wiring device, and particularly to a wiring device for wiring signal lines of distributed terminals.

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]

Conventionally, efforts have been made to route signal lines of a large number of terminals efficiently and without spoiling the aesthetics. A typical example is an undercarpet type wiring device that is widely applied to the floors of office buildings. This also means pre-wiring the signal lines under the carpet with each end unsupported. This allows signal lines to be laid freely without spoiling the aesthetics of the office floor.

However, 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 becomes very high. For this reason, running costs are high in offices that undergo frequent redecoration.

Therefore, the applicant prototyped the following wiring device. The present invention is based on this wiring device.

FIG. 5 is a diagram showing an outline of a wiring device forming the premise of the present invention. In this figure, 11 is a wiring cable, which connects a plurality of distributed terminals (TE:
ipment) 16, and is wired in a loop throughout. The distribution cable 11 consists of 9 bundles of line lines 12 (part of the distribution cable 11 is shown in cross section).Information outlets 13 are inserted in series with the distribution cable 11 at each unsupported end.Each information outlet 13 is
A line connection unit 14 for selectively connecting a corresponding terminal 16 and a desired line 12 in the distribution cable 11 via a corresponding switch, and selective opening/closing control of each switch in the line connection unit 14 and a connection control section 15. The line connection unit 14 and the corresponding terminal 16 are connected by a signal line 17. Extension connections between these terminals,
External line connection with external terminal via central office line is at Yokonai switchboard 19.
It will be held at

FIG. 6 is a diagram showing a first example of a conventional wiring device, in which the line connection section 14 in the information outlet 13 is particularly emphasized. Note that similar components are designated with the same reference numbers or symbols throughout the drawings. In this figure, as an example, a case where n (n=4) terminals 16 are placed under the control is shown, with the information outlet 13 placed second from the left on the upper side of the figure as a representative. These terminals 16 are led to the line connection section 14 via corresponding modular jacks 18, respectively.

This line connection section 14 connects N terminals 16 (N=12).
to any one of the circuit lines 12 of , without overlapping with other terminals.

According to the first example, a complete matrix is formed between four terminals and 12 line lines in the line connection section 14, and a switch (indicated by a small circle) is arranged at each intersection of the matrix. There is. Note that a row of switches arranged at the right end of the information outlet 13 are switches for disconnecting lines, and are different from the switches related to the present invention.

FIG. 7 is a diagram showing a second example of a conventional wiring device, and this diagram also emphasizes the line connection section 14 in the information outlet 13. According to this second example, the line connection section 14
The internal switches are designed so that each terminal can freely select and connect to three of the 12 lines 12 without duplication with other terminals 16.

[Problem to be solved by the invention]

The line connection unit 14 according to the first conventional example described above is ! i!
! It has a high degree of freedom of choice and is ideal considering its original function. However, the number of switches required for each information outlet 13 becomes extremely large, resulting in problems such as increased cost and increased size. It is thought that the problem of increasing size could be solved by using electronic switches (transistors) instead of relay contacts for each switch, but electronic devices for this kind of use are currently difficult to obtain commercially. Even if I can get it, I'm concerned about Talostalk between adjacent switches. Furthermore, each switch is always active, and the power consumption and heat generated by these electronic devices cannot be ignored. Furthermore, since each switch is not opened or closed frequently and is only set to open or closed when adding or relocating a terminal, most of the switches do not perform their original functions. This is uneconomical.

The problems in the first example described above are largely eliminated by the second example. However, this second example also has its own problems. The problem is that the degree of freedom is extremely low. That is, referring again to FIG. 7, only three of the twelve lines 12 can be freely selected by any of the four terminals 16. This becomes a significant constraint when adding or relocating terminals.

Therefore, in view of the above-mentioned problems, it is an object of the present invention to provide a wiring device that is inexpensive without being bulky and has a degree of freedom close to that of the complete matrix type switch of the first example. .

[Means to solve the problem]

FIG. 1 is a diagram showing the principle configuration of the present invention. This figure shows one of the plurality of information outlets 13 in the wiring device, and the main components are a line branching unit 21 and a line selection unit 22.

The line branch unit 21 connects N branch lines 23 corresponding to each of the N (N=12 in the figure) line lines 12 and the corresponding line lines 12 and branch lines 23 under control by the control unit 15. It consists of N electrically controlled switches 24 that are connected or disconnected from the source. Also,
Each line selection unit 22 has N branch lines 23.
It consists of n (n=4 in the figure) mechanically operated switches 25 that can be connected to any one of the terminals, and is connected to 0 terminals 16 via the n mechanically operated switches 25. . Note that 24' is a line disconnection switch.

[Operation] The electrically controlled switches 24 corresponding to the N circuit lines 12 that can be assigned to the information outlet 13 among the N circuit lines 12 are turned on to connect them to the corresponding branch lines 23 respectively. The n mechanically operated switches 25 freely select these assigned n branch lines 23 and connect them to each terminal 16 via the modular jack 18.

As is clear from FIG. 1, the number of electrically controlled switches 24 may be as many as the number of circuit lines 12. This is because the mechanically operated switch 25 can select the desired branch line 23 with a considerable degree of freedom. Such a degree of freedom can only be achieved with a v11ti operated switch (this will become clear in later examples). On the other hand, the inside of the line branching unit 21 is configured with an electrically controlled switch 24 as follows. The allocation of each information outlet of the N circuit lines 12 must be determined by comprehensively determining the relationship among all the information outlets in the wiring device. For this reason, the operator controls all information outlets 1 via the central controller (CC in Figure 1).
A connection command is sent individually every three times.

This connection command is naturally sent in the form of an electrical signal, and the connection control section 15 in each information outlet 13 turns each switch on or off in the form of an electrical signal. Therefore, these switches must be electrically controlled switches and are arranged as electrically controlled switches 24 as shown.

On the other hand, from the terminal side of each information outlet 13, which terminal 16 is connected to which circuit line 12 is a local issue, and it is more convenient for the operator to manually set it individually. Since it is a manual switch, a mechanically operated switch is easier to use and offers greater freedom of choice.
