客に迷惑をかけていた。従って、テールコードの交換を
−゛定の使用年月を越えると行う方式をとっていた。Elevators are equipped with a multi-core tail cord for signal lines and power lines between the car and the elevator machine room, but as this tail cord repeatedly bends as the car moves up and down, the internal stranded wires tend to break down over time. disconnects due to fatigue. However, it is not known when a stranded wire will break, depending on the frequency of use and the hanging bending radius, so when a break occurs, it takes time to investigate the cause and prepare the tail cord, as well as causing inconvenience to the customer. Therefore, a system has been adopted in which the tail cord is replaced after a certain number of years of use.
本発明は、撚線の抵抗の変化を定期的に確認し、換を行
い無駄な時間を除くものである。The present invention periodically checks changes in the resistance of the stranded wires and replaces them to eliminate wasted time.
本発明の要点はテールコードの両端を挿入式接続器とし
、この接続器に抵抗測定器を接続するこ算し一断線に至
らぬ前に交換を行う手段を設けた −とによ
り、導体の抵抗を測定し、導体の太さに逆ことにある。The key points of the present invention are that both ends of the tail cord are connected to insertion type connectors, a resistance measuring device is connected to these connectors, and a means is provided for replacing the wire before it becomes disconnected. Measure and invert the thickness of the conductor.

接続する方法もある。This tail cord 6 is connected to the terminal box 5A in the control panel 5 in the machine room.
It is connected by a convex connector and a concave connector at the bottom of the car 1, and is supported by a hanging bracket 8 at the bottom of the car 1.In the connection box 9 at the top of the car 1, power and signal wires are connected to each device (not shown) related to the car 1. A terminal connector (concave connector) 10A is connected to a terminal connector (convex connector) 11A on the tail cord side. still,
In the case of a long stroke, as shown in Figure 2, a joint box 7 is installed in the middle.
There is also a method of providing a connection box 9 on the car 1 and connecting it with a concave and convex connector like the connection box 9 on the car 1.
