Description

DETAILED DESCRIPTION OF THE INVENTION Among the electrical work processes for structures such as buildings, there is a process of running electric wires through conduits buried in concrete.

This process involves pushing a steel wire (a flexible FILI wire) through one end of the buried electrical conduit (actually, a box called an outlet box is connected to the electrical conduit and buried underground).

@Attach the electric wire to the tip of the steel wire that comes out from the other end of the wire tube (actually the outlet box),
The worker who pushed the steel wire in gradually pulls it out, and the worker who installed the wire pushes the wire in while being careful not to get the wire tangled.

At this time, both workers shouted to each other,
They breathe in unison, but if the distance between the two parties is mq p, or if they are in different rooms or due to construction noise, they may not be able to hear the chirps, so they may shout louder or a third party may , there was the inconvenience of having to relay the cacophony.

Furthermore, when a transceiver or the like is used, work must be interrupted to make a telephone call, which has the drawback of extremely low efficiency.

The present invention relates to a telephone-type steel wire that allows telephone calls to be made while conducting wiring work.

Conventional steel wire was only used for wiring, but
This steel wire is used as one line of the communication circuit, and the other line uses a buried 711 wire tube to enable communication with a headphone-type communication device.

To explain this with reference to the drawings, the conventional steel wire (2) is used as a storage tube (3) when not in use, as shown in Figure 1.
).

Figures 2 and 3 show the steel wire of the present invention, with a metal guide ring (4) sandwiching a connecting terminal (5) at an appropriate position in a storage tube (3) and fixed with a bolt (6). ing.

On the other hand, one end b's of the steel wire (2) coated with an insulating coating (1) is electrically connected to the slider (7), which is electrically connected to the guide ring (4). , in a slidable state.

Figure 4 is a block diagram of the communication circuit, with steel wire (2)

(9) into the other outlet box (
Take out from 8.

Remove the coating from one end of the wire bundle (10) to be wired to the protruding tip, attach it, and wrap it with vinyl tape or the like so that it is electrically connected.

At the other end of the wire bundle (10), there is a headphone-type communication device (11).
Connect the - wire of P) with a clip, etc., and connect the other wire with an outlet box (8 uni clip, etc.).

-M it of the other headphone-type communication device (11) is connected to the connecting terminal (5) electrically connected to the steel wire (2) with a clip or the like, and the other line is also connected to the out-left box (8).

With the above configuration, the communication circuit includes a headphone type communication device (11), a connection terminal (5), and a steel wire (2).
), wire bundle (10), headphone type intercom (11')
, out left box (8'), conduit (9), out left box (8), headphone type intercom (1)
1) It consists of the following routes, and both workers can talk on the phone.

In Figure 5, the slider (7) is fixed to the storage tube (3), and the steel wire (2) is connected to the guide ring (4) so that the guide ring (4) can rotate. , a similar effect can be obtained.

Figure 6 shows the guide ring (4) fully filled and the slider (7)
In order to move smoothly, the roller is shaped like a roller and is constructed with a springy roller fixing piece (12).

In Figure 7, the steel wire (2) is made in-house, so gold 71 (13), which has good conductivity, is welded or glued to the outer periphery of the steel wire (2) to improve its electrical conductivity. (1) has been applied.

Figure 8 shows that a good conductive wire (14) is used as a part of the steel wire (2) instead of a good O conductive metal (13).
J+l was determined.

By using the talking steel wire of this invention, there is no need to make loud calls, and you can do it in a low voice.You can easily carry out wiring work even at noisy construction sites or in places where the calls cannot be heard. Ru.

In addition, there are places where the specific heat is far away, and there is no cracking sound.
Since you can have a casual conversation, you can discuss the next task and reduce labor costs.
