Abstract

PURPOSE:To provide a sensor mounting jig which is applicable even to a flat type tail cord to sense its defect easily. CONSTITUTION:A flat cable 5 is composed of a plurality of element cables laid in line, and conductor defect of this cable 5 is sensed by sensors 3 which are installed as mating with cable conductors 6, wherein a jig 1 moves the sensors 3 along the flat cable 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor mounting jig suitable for mounting a sensor for detecting a defect in a cable and for stably moving the sensor.

[0002]

2. Description of the Related Art Conventionally, a method of detecting a conductor defect of a cable has detected the defect with one sensor for each conductor. Therefore, there is no sensor that collectively detects conductor defects in a flat cable that is configured by arranging a plurality of cables in parallel, and there is no jig for attaching this sensor to the cable.

[0003]

As described above, since there is no sensor mounting jig for a flat cable having a plurality of conductors, in order to detect a conductor defect of the flat cable, one conductor is used. 1 for each conductor, similar to a cable
The defect had to be detected by two sensors, and the workability was very poor. Also, with a cable arranged at a high lift in the vertical direction, such as a tail cord of an elevator, the above-mentioned detection method cannot be applied and its defect cannot be detected.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a sensor mounting jig capable of easily detecting the defect in a flat tail cord.

[0005]

SUMMARY OF THE INVENTION The above object is to eliminate the conductor defect of a flat cable in which a sensor for detecting a conductor defect of a cable is arranged in parallel in a sensor mounting jig for mounting the sensor on the cable. This is achieved by mounting a plurality of sensors for detecting each conductor of the flat cable and moving the plurality of sensors along the flat cable.

[0006]

According to the present invention, with the above-mentioned structure, the sensor for detecting the conductor defect of the flat cable can be attached to the flat cable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a cross-sectional view showing the positional relationship between a flat cable and a sensor.

Reference numeral 1 is a lubricant 2, a sensor 3, and a feed roller 4.
It is a sensor mounting jig composed of and. Reference numeral 5 is a flat cable composed of a plurality of conductors 6 arranged in parallel. An example of the flat cable 5 is an elevator tail cord.

Next, the operation of detecting a defect of the flat cable using this jig will be described with reference to FIGS. 1 and 2. Figure 2
FIG. 4 is a vertical cross-sectional view showing a positional relationship between a flat cable and a sensor. The same reference numerals indicate the same parts as in FIG.

First, the outer peripheral surface of the flat cable 5 is sandwiched between the slip agent 2 of the sensor mounting jig 1 and the feed roller 4.
Then, as shown in FIG. 2, by moving the sensor mounting jig 1 along the flat cable 5, the sensor corresponding to each conductor detects a defect in the conductor.

As the sensor used in the present invention, the sensor shown in FIG. 3 can be considered. FIG. 3 is a cross-sectional view showing the positional relationship between the sensor and the cable.

Reference numeral 7 is an eddy current deep wound sensor composed of a core 8 and a coil 9 wound around the core 8. By passing an AC power supply to the coil 9 and bringing the sensor generating magnetic flux close to the cable surface, the cable 5
It is possible to detect a defect in the conductor 6 of FIG.

Since the sensor mounting jig is constructed as described above, each sensor always maintains a fixed distance from the flat cable, so that defect detection of the flat cable can be detected with high sensitivity. Further, since it can be moved along the cable, it is possible to significantly reduce the working time and detect the conductor defect of the flat cable.

[0014]

Since the sensor mounting jig is constructed as described above, each sensor can be moved along the cable, and the working time can be greatly shortened to detect the conductor defect of the cable.
