  In recent years, the spread of broadband and the advancement of information technology such as digitalization and diversification of TV broadcasts has been tremendous, and after constructing communication cables and broadcast cables, new communication cables and broadcast cables are constructed in a short period of time. In many cases, however, it is not possible to add new wiring to the multi-connection cable, and it is necessary to construct a new communication cable or broadcasting cable.

  An object of the present invention is to provide a cable wiring system and a cable wiring construction method that can be easily constructed even when a large number of rooms are provided like an apartment house, and a new cable can be easily routed after construction, in view of the above drawbacks. There is to do.

The cable wiring system according to claim 1, wherein a collective control device including a processing device and a distribution device, to which an external line is connected, and an information outlet installed in a building room are a communication cable and / or a broadcasting cable. And a sheath tube for additional wiring having an inner diameter of 7 to 16 mm is covered with a resin tube, and the side surfaces of the resin tube of both the communication cable and / or broadcasting cable and the additional wiring sheath tube are flexible and can be separated . It is formed by a multi-connection cable that is bridge-connected in the length direction by a long resin sheet, and the multi-connection cable has an outer shape of the communication cable and / or the broadcast cable and the additional wiring sheath tube. Two cables, a communication cable and / or a broadcasting cable with a small outer shape around the largest additional wiring sheath tube, are used for the long resin sheet and the additional wiring. State center of the tube is connected is made so as not disposed on a straight line, the multi-articulated cable by bending the long resin sheet around the additional wiring sheath tube, the flattened state or rounded The communication cable and / or the broadcast cable can be accommodated within one projection plane of the additional wiring sheath tube in either a flat state or a rounded state. Further, the multi-connection cable is fixed to a building frame at a predetermined interval.

  The collective control device is composed of a processing device and a distribution device, and is not particularly limited as long as it has a function of processing and distributing information sent from the outside line and sending it to each communication cable and broadcasting cable. Any known collective control device can be used.

  The communication cable processing device includes a router, the distribution device includes a hub, the broadcast cable processing device includes a booster, and the distribution device includes a distributor. In a telephone line, an exchange device is an example of a combination of a processing device and a distribution device.

  The information outlet is an outlet to which information such as an outlet to which a modular jack or the like is attached, a TV antenna connection outlet, or the like can be connected, and any conventionally known information outlet can be used.

  The above-mentioned sheath pipe for additional wiring is used for additional wiring of optical fiber cables, TV feeder cables, TV coaxial cables, LAN cables, etc. as necessary after the construction of the cable wiring system. Tubes with both shape retention and flexibility are preferred because they are installed together with broadcast cables, for example, soft vinyl chloride resin, ethylene resin, propylene resin, acrylic resin, urethane resin, silicon resin, etc. Resin pipes such as resin and rubber are preferred.

Further, the inner diameter of the additional wiring for the sleeve pipe, if necessary, an optical fiber cable, TV feeder cable, TV coaxial cables, since the cable such as a LAN cable to additional wiring is 7～16Mm.

The multi-connection cable is a cable in which a communication cable and / or a broadcast cable and a sheath pipe for additional wiring are connected . The communication cable and the broadcast cable include one or a plurality of communication cables or broadcast cables. Or both of them may be used in combination.

The multi-connection cable integrates a communication cable and / or broadcasting cable and a sheath tube for additional wiring, which not only simplifies the construction, but also ensures a certain level of rigidity, so an additional cable is added. Easy to install. In addition, it becomes easier to fix the building to the body.

Multi articulation cable includes a through credit cables and / or broadcast cables, inner diameter sheath tube for additional wiring 7~16mm is covered with a resin tube, side surfaces of both of the resin tube length by a flexible elongated resin sheet It is formed by bridge connection in the vertical direction.

  Since the resin tube is a tube that covers a communication cable and / or a broadcast cable and a sheath tube for additional wiring, it is preferably formed of a flexible resin, for example, a soft vinyl chloride resin, an ethylene system, or the like. Examples thereof include resins such as resins, propylene resins, acrylic resins, urethane resins, silicon resins, and rubbers.

  Also, since the side surfaces of the resin tube are bridge-connected in the length direction by a flexible long resin sheet, bending the long resin sheet deforms it into a flat state, a rounded state, etc. And can be wired in accordance with the shape of the space where the multi-connection cable is wired.

  Examples of the resin constituting the long resin sheet include soft vinyl chloride resins, ethylene resins, propylene resins, acrylic resins, urethane resins, silicon resins, and rubber resins. Since the sheet connects the side surfaces of the resin tube, the same resin as the resin constituting the resin tube is preferable.

Furthermore, the width of the long resin sheet is preferably 5 to 15 mm.

By doing so, it is possible to route the communication cable, the broadcasting cable, and the cable that is additionally wired to the additional wiring sheath tube by separating them from each other for a certain distance, so that there is no mutual interference due to signal leakage between cables be able to.

The multi-connection cable includes a communication cable and / or broadcasting having a small outer shape around the additional wiring sheath tube having the largest outer shape among the communication cable and / or broadcasting cable and the additional wiring sheath tube. Two cables are connected so that the center of the long resin sheet and the additional wiring sheath tube are not arranged in a straight line, and the multi-connection cable is connected to the periphery of the additional wiring sheath tube . By bending the long resin sheet, the wiring can be deformed in either a flat state or a rounded state, and the communication cable and / or broadcasting can be performed in either the flat state or the rounded state. Two of the cables for use can be accommodated in one projection plane of the sheath tube for additional wiring.

  To fit within one projection plane means that when a communication cable and / or broadcasting cable and a sheath tube for additional wiring are pressed against a large one by bending a long resin sheet, , Which means that all other small outlines fit within the width of the large outline.

  FIGS. 3A and 3B are schematic views showing a state where the communication cable and the broadcasting cable are accommodated in one projection plane of the additional wiring sheath tube. In the figure, reference numeral 1 denotes a sheath pipe for additional wiring. The broadcasting cable 2 and the communication cable 3 are accommodated in one projection plane of the additional wiring sheath pipe 1 by bending a long resin sheet.

  The above multi-connection cable can accommodate all other small outer shapes within the width of the large one by bending the long resin sheet, and can be installed in a narrow gap to the collective control device. Since the introduction opening of the multi-connection cable can be made smaller, the thickness of the collective control device can be reduced. By constructing the multi-connection cable so that the maximum outer diameter direction is up and down, bending of the multi-connection cable can be suppressed. By bending the multi-connection cable in a direction perpendicular to the maximum outer diameter direction, the multi-connection cable can be bent with a minimum bending R.

  The strength of the multi-connection cable is preferably such that the hanging distance is 30 to 90 mm when one end of a multi-connection cable having a length of 150 mm is fixed and a weight of 100 g is suspended from the other end.

  When the drooping distance by the above test is smaller than 30 mm, it becomes too hard and it becomes difficult to route the multi-connection cable when wiring to the building, and when it is larger than 90 mm, it becomes too soft and fixed to the building. In this case, the thickness is preferably 30 to 90 mm because there are defects such as bending at the time, sudden bending at the extra length, and difficulty in passing a new cable when it is installed in the sheath tube.

The multi-connection cable is fixed to the building frame at a predetermined interval, and the collective control device and the information outlet are connected. However, when the bundling cable or multi-connection cable is fixed to the building frame, It is preferable that the connecting cable is fixed at intervals of 1 to 3 m so as not to hang down due to its own weight.

In addition, in a cable wiring system for a multi- storey building, when the building is an even-floor building, the connection of the multi-connection cable and the information outlet is wired from the ceiling of the room to the odd-floor room, and the even-floor room Wiring from the bottom of the room is preferable, and if the building is an odd floor, the connection of the multi-connection cable and the information outlet is wired from the ceiling of the room to the odd floor room. It is preferable that the room and the room on the top floor are wired from the bottom of the room.

  By doing so, the wiring route to each room on the first floor and the second floor or more is simplified, and the wiring distance to both floors is substantially the same, so that the workability is excellent.

Further, when the wiring to the apartment or the like, is often apartment like a simple refractory structures or refractory structure, the number of through holes of Sakaikabe portion is better as low as possible is preferred, the upper and lower second floor in the cabling system Workability is excellent in one place in the room.

  In the above cable wiring system, information input from the outside line is processed and distributed by the collective control device, and connected to an information outlet installed in the room by a bundling cable or a multi-connection cable, so that necessary information can be easily obtained from the information outlet. Can be taken out.

In addition, the multi-connection cable is fixed to a building frame such as a beam at regular intervals even when installed on the back of the ceiling, etc., and the communication cable and / or the broadcast cable and the additional wiring sheath tube are provided. Since they are integrated, have mechanical strength, and are less bent, the multi-connection cable is fixed to the housing with less bending. Therefore, when a new cable is wired in the sheath tube, the sheath tube can be wired without being damaged or damaged by the frictional force between the wall surface of the sheath tube and the cable.

According to a fifth aspect of the present invention, there is provided a cable wiring construction method in which one end of the multi-connection cable according to claim 1 is connected to a collective control device including a processing device and a distribution device, to which an external line is connected, and the multi-connection cable is connected to the collective control device. The communication cable and / or the broadcast cable and the additional wiring sheath tube communication cable and the broadcast cable are fixed to the building frame at a predetermined interval, and the other end is installed in the building interior. Alternatively, the additional wiring is divided and connected.

As described above, the multi-connection cable is bridged in the longitudinal direction by a long resin sheet in which the side surfaces of the resin tube of both the communication cable and / or broadcasting cable and the additional wiring sheath tube are flexible and can be divided. The multi-connection cable is connected to the communication cable and / or the broadcasting cable and the additional wiring sheath tube around the additional wiring sheath tube having the largest outer shape. Two communication cables and / or broadcasting cables having a small external shape are connected so that the center of the long resin sheet and the additional sheath tube are not arranged on a straight line. , by bending the long resin sheet around the additional wiring sheath pipe, also it can be routed to deform in either flat state or curled state, Bian In either state or rounded state, two of the communication cable and / or broadcast cable have been made to fit to one projection plane of the additional wiring sheath tube.

  The multi-connection cable can be wired in a flat state, a rounded state, etc. by bending a long resin sheet.

  Moreover, since the additional sheath tube having an inner diameter of 7 to 16 mm is integrated, cables such as an optical fiber cable, a television feeder cable, a television coaxial cable, and a LAN cable can be additionally wired as necessary. In addition, if the nominal line is inserted in advance into the sheath pipe for additional wiring, the additional wiring of the cable can be made easier.

In addition, as described above, the long resin sheet preferably has a width of 5 to 15 mm.

  The above multi-connection cable can be routed with a certain distance between the cable for communication, the cable for broadcasting, and the cable for additional wiring, and wiring so that there is no mutual interference due to signal leakage between cables. can do.

Further, the strength of the multi-connection cable is preferably such that the hanging distance is 30 to 90 mm when one end of the multi-connection cable having a length of 150 mm is fixed and a weight of 100 g is suspended from the other end.

As a method for fixing the multi-connection cable to the building frame, any conventionally known method may be employed. For example, a nail is hit against the building frame such as a beam or a wall, and the multi-connection cable is wired to the nail. And a method of binding with a string or the like, and a method of driving a multi-connection cable on a building frame such as a beam or a wall with a U-shaped nail.

The fixed interval may be determined as appropriate, but the multi-connection cable has a relatively mechanical strength because the communication cable and / or broadcasting cable and the sheath tube for additional wiring are integrated, and it is difficult to bend due to its own weight. Therefore, no bending occurs at an interval of 1 m, but an interval of 1 to 3 m is preferable because bending becomes easier at 3 m or more.

  The cable wiring construction method can easily distribute and distribute a wide variety of cables to an information outlet installed indoors, and can also easily add an additional cable.

In addition, the multi-connection cable is integrated with the communication cable and / or broadcasting cable and the sheathing tube for additional wiring. by fixing a predetermined interval precursor of buildings etc., it can flex multiple concatenated cable is less construction. Therefore, when a new cable is wired in the sheath tube, the sheath tube can be easily routed without being damaged or damaged by the frictional force between the wall surface of the sheath tube and the cable.

Also, when connecting the multi-connection cable to the information outlet , the long resin sheet is torn near the information outlet and the multi-connection cable communication cable, broadcasting cable or additional wiring sheath tube is divided, the communication cable, Each of the broadcasting cable and the additional wiring sheath tube is preferably connected to a predetermined information outlet.

  By doing so, all the cables can be wired at once by the multi-connection cable, and can be freely connected to a predetermined information outlet at a predetermined position according to the use state.

  The building is an apartment house, and is preferably wired to each room, which enables prior information wiring in the apartment house.

  In particular, information wiring in small rental apartments often involves only wiring a telephone line to each room. For example, in order to construct a broadband environment, the only way to construct a broadband environment is to pull the optical fiber directly from the outer wall or the like into the room. However, by doing this, communication and broadcast wiring can be easily constructed, and even when additional wiring is performed, construction can be performed without damaging the exterior and interior of the building.

Since the configuration of the cable wiring system of the present invention is as described above, the information input from the outside line is processed and distributed by the collective control device and connected to an information outlet installed indoors by a multi-connection cable. Necessary information can be easily extracted from

In addition, the multi-connection cable is fixed to a building frame such as a beam at regular intervals even when installed on the back of the ceiling, etc., and the communication cable and / or the broadcast cable and the additional wiring sheath tube are provided. Since they are integrated, have mechanical strength, and are less bent, the multi-connection cable is fixed to the housing with less bending. Therefore, when a new cable is wired in the sheath tube, the sheath tube can be wired without being damaged or damaged by the frictional force between the wall surface of the sheath tube and the cable.

  Since the configuration of the cable wiring construction method of the present invention is as described above, a wide variety of cables can be easily distributed to information outlets installed indoors, and additional cables can also be easily wired. it can.

In addition, the multi-connection cable is integrated with the communication cable and / or broadcasting cable and the sheathing tube for additional wiring. more be fixed at predetermined intervals in the skeleton of a building etc., can be reduced construction for bending a multi-articulated cable. Therefore, when a new cable is wired in the sheath tube, the sheath tube can be easily routed without being damaged or damaged by the frictional force between the wall surface of the sheath tube and the cable.
