BRANCH CONNECTING STRUCTURE OF COMMUNICATION CABLE FOR ELEVATOR}

The present invention relates to an elevating electric wire branch connection structure, and more specifically, the number of floors in which a hall button and an elevator are located at one side of an elevator entrance inside a building and a machine room for controlling the elevator are used to call the elevator at each floor. It relates to the branch connection structure of the hoistway wire installed on the wall of the hoistway for the communication between the indicators.

In general, the elevator 10 for transporting people and cargo up and down is equipped with a hall button 6 for the user to call the elevator on one side of the elevator entrance to each floor of the installed building, the number of floors where the elevator is currently located An indicator 4 is provided to indicate in real time, and the hall button 6 and the indicator 4 are provided at an upper part of the hoistway 30, which is a passage through which the hoister 10 moves up and down, and controls the hoister 10. Is electrically connected to the controller 22 of the machine room 20 to perform communication.

At this time, the communication cable connecting the hall button 6 and the indicator 4 and the machine room controller 22 is commonly referred to as a hoistway wire 1, and the hoistway wire 1 is along the wall surface of the hoistway 30. It is fixedly installed vertically, branched at each floor, and connected to the hall button 6 and the indicator 4. 1 schematically shows the branch connection structure of such a conventional hoistway wire 1.

The conventional hoistway wire 1 is configured in the form of a circular cable, and a plurality of communication lines are built into the sheath of the wire. Conventionally, in order to branch the hoistway wire and connect it to the hall button 6 and the indicator 4, as shown in FIG. 1, the hoistway wire 1 is made into an annular shape at the branch point, and then fixed with a cable tie. After stripping the coating on one side of the ring, one end of the branch line 2 was connected to each communication line, and the other end of the branch line 2 was connected to the hall button 6 and the indicator 4. And, in order to prevent the flow by the fixed fixing means 40, such as a fixed clip or a fixed bracket at regular intervals to secure the hoistway wire to the hoistway wall.

However, according to this method, there is a complicated and complicated disadvantage, because it has to go through a number of working steps that have to make the hoist wire into a ring shape, secure it with cable ties, and strip the sheath. The cable tie is dismantled by its own load, which causes the loop to be released and the connection to the hole button or indicator is broken.

On the other hand, since a plurality of communication lines embedded in the covering of the hoistway wires are configured to transmit different signals, the positions to which each communication line should be connected are determined, and for this purpose, distinction of each communication line is required. However, in the case of using the circular cable as described above, since the communication lines are mixed with each other inside the sheath, it is difficult to distinguish the communication lines, and there is a fear of communication failure caused by connecting the communication lines to the wrong position.

After peeling off the cover and connecting the branch line, the branch connection part is wound with an insulated tape to finish the process. As time passes, the insulated tape drops and the communication line is exposed to the outside, which may cause an electric leakage or electric shock. Due to the poor waterproofing, there is a risk of leakage due to the seepage of water sprayed during grinding work on new building floors or when cleaning floors.

In addition, the conventional method as described above can only directly work on the elevator installation site, it is impossible to mass production in advance in the factory in a harness type (harness) has a problem that can lead to a rise in manufacturing cost and labor costs.
