Description

TECHNICAL FIELD The present invention relates to an information outlet.

[Prior Art] Conventionally, there has been proposed a home bus system as described in, for example, "Electricity and Construction, September 1986."
In this home bus system, a home bus controller is connected to an information outlet through a bus cable, a distributor, etc., and a terminal device can be connected to this information outlet.

As the bus cable, a multi-core cable suitable for transmitting control signals and a coaxial cable suitable for transmitting video signals are used.

By the way, an information outlet is generally installed on a wall surface of a building, and an in-wall connection port to which a multicore cable for transmission or a coaxial cable for transmitting an information signal is connected, and a multicore cable for a terminal or a coaxial cable connected to a terminal device. Is connected to the outside of the wall.

Here, in the conventional information outlet, a multi-contact jack (modular jack) into which the multi-contact plug provided on the outer multi-core cable can be inserted is provided at the outside wall connection port to which the multi-core cable for terminals is connected. ing. As a result, the external connection port does not spoil the aesthetics of the room and allows the terminal device to be easily attached to and detached from the outlet.

[Problems to be Solved by the Invention] However, in the conventional information outlet, the in-wall connection port to which the transmission multi-core cable is connected has a plurality of screw terminals for individually screwing the respective core wires of the multi-core cable. I'm just prepared.

For example, the outlet described in JP-A-58-73972 has a transmission jack, but only has a multi-contact jack in the front opening facing the outside of the wall of the transmission jack, and the wall of the transmission jack is not provided. A screw type terminal is used on the rear surface facing inward. That is, the transmission wire extending from the spring block on the rear surface (rear surface) of the outlet is connected to the screw type terminal of the jack body.

For this reason, it takes time to connect each core wire of the multicore cable for transmission to the screw terminal of the in-wall connection port, and the electrical connection may become unstable or break depending on the strength of the screwing. Also, adjacent core wires may be short-circuited to each other.

It is an object of the present invention to provide an information outlet capable of connecting a multicore cable for transmission in a short time and with high reliability.

[Means for Solving the Problems] The present invention provides an intra-wall connection port installed on a wall surface of a building to which a multicore cable for transmission for transmitting an information signal is connected, and a multicore cable for a terminal connected to a terminal device. In an information outlet having an external wall connection port to be connected, a multi-contact jack into which a multi-contact plug provided on a multi-core cable can be inserted is provided on both the internal wall connection port and the external wall connection port. It is a thing.

[Operation] The information outlet of the present invention is installed on the wall surface with the multi-contact plug of the transmission multi-core cable inserted in the multi-contact jack provided in the wall connection port, and then installed on the outside wall connection port. Information can be transmitted to the terminal equipment by inserting the multi-contact plug of the multi-core cable for terminals into the multi-contact jack.

Here, since the information outlet has a multi-contact jack also provided in the wall connection port, the multi-core cable for transmission can be connected with one touch, and the electrical connection state can be surely and stabilized, and they are adjacent to each other. There is no possibility of mutual short circuit of core wires. That is, the multicore cable for transmission can be connected in a short time with high reliability.

In particular, the number of steps can be reduced when installing a unit in a unit house.

The HBC 10 is installed in a specific unit 17 (specific room) of the house 16, and the distributor 12 is installed in each of the units 17 of the house 16. As a result, the HBC 10 is connected to the information outlet 13 installed in each room of the house 16 via the composite bus cable 11 and the distributor 12. As shown in FIG. 8, the network topology for connecting the HBC 10 and the information outlet 13 is a bus-and-star system in which branching is appropriately performed from the distributor 12 to the information outlet 13;
Various topologies can be used, such as a bus system in which the wiring is sequentially fed in.

As shown in FIG. 5, the composite bus cable 11 includes a transmission multi-core cable (for example, 6-core or 8-core) 18 suitable for transmitting control signals and a transmission coaxial cable 19 suitable for transmitting video signals. It is composed of a composite of 11A is a sheath.

Each information outlet 13 is connected to the composite bus cable 11 as described above, and is connected to the corresponding terminal device 14 in a multi-core cable 20 for terminals and a coaxial cable for terminals.
21 is connected, and thereby the HBC 10 and each terminal device 14 can be connected.

As the terminal device 14 corresponding to each information outlet 13,
For example, as shown in FIG. 7, a window, a door lock sensor 14A, a smoke sensor 14B, a gas leak sensor 14C, a telephone 14D, and a television 14E are installed in the same room as the information outlet 13.
Etc.

 The NT15 is a termination function for the public network 15A, the broadcast 15B, and so on.

In this embodiment, the home bus and the terminal device 14
Interface matching (electrical matching such as signal and impedance, logical matching such as signal format, etc.)
This is done by an IFU (interface unit) built in the terminal device 14. However, in the implementation of the present invention, this IFU may be built in the information outlet 13 or may be interposed between the information outlet 13 and the terminal device 14.

Then, the information outlet 13 is installed on the wall surface of the house 16 and, as shown in FIG. 1, two multicore inner wall connection ports to which the multicore cable 18 for transmission of the composite bus cable 11 is connected.

Is provided with a locking portion with which the locking piece 26A can be disengaged.

 Next, the operation of the above embodiment will be described.

The information outlet 13 is installed on the wall surface with the multi-contact plug 26 of the transmission multi-core cable 18 inserted in the multi-contact jack 27 provided in the multi-core wall connection port 22, and then installed on the wall for multi-core. Information can be transmitted to a terminal device by inserting the multi-contact plug of the multi-core cable 20 for a terminal into the multi-contact jack 28 provided in the external connection port 24.

Here, the information outlet 13 is a multi-core wall connection port.
Since 22 is also provided with multi-contact jack 27, the transmission multi-core cable 18 can be connected with one touch, the electrical connection state can be reliably and stabilized, and there is no risk of mutual short-circuiting between adjacent core wires. .
