Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic disconnection tester for multi-pair communication cables.

[Prior Art] FIG. 3 shows a conventional example of an automatic disconnection tester for multi-pair communication cables. As shown in the figure, the automatic disconnection tester tests a gearbox 2 attached to a gearbox support 1 on a chassis, and a coated core wire 3a of a multi-pair communication cable 3 installed on the bottom surface of the gearbox 2. A pair of grooved rotary rollers 4 (hereinafter referred to as rotary rollers) that pick up books one by one, a rotary belt 5 provided below and having the same drive 9, facing each other with a predetermined distance below the rotary belt 5. Electrodes 6 arranged and charged on one side
A pair of opposing plates 7 having the same structure, a grounding plate 8 for enclosing core wires provided at the bottom of the opposing plates 7, and the like are provided.

In the automatic disconnection testing machine constructed in this manner, the rotating belts 5 are also paired, and have the function of sandwiching the coating of the coated core wire 3a such as polyethylene and peeling it off several centimeters from the tip. Core wire 3b with peeled coating
falls between the opposing plates 7 at the bottom, and a direct current is generated at the charged electrode 6.
A voltage of 500V is applied to the core wires 3 which have already passed between the opposing plates 7 and are stored in the core wire collective storage grounding plate 8.
A crosstalk test is conducted with c.

This makes it possible to conduct a cross-wire test on a multi-pair communication cable 3 ranging from several to several thousand fibers while stripping the sheath at the same time, which is not only convenient for the continuity test that will be performed later, but also reduces the time required for the cross-wire test by hand. It was much shorter and more efficient.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, the coated core wire of the multi-pair communication cable is manually supplied to the automatic break test machine, so even when there are many test slots, testing is required for each machine. The drawback was that a person had to be present from beginning to end.

The present invention has been made in view of the above points,
The object of the present invention is to provide an automatic disconnection tester for multi-pair communication cables, which allows tests to be carried out smoothly and automatically without a person being present throughout.

[Means for solving the problem] The above purpose is to provide a testing machine with a group of coated core wires divided into a plurality of pieces of a multi-pair communication cable as the coated core wires are processed and removed on a rotating roller. This can be achieved by providing an automatic conveying device that sequentially supplies each group of coated core wires onto a rotating roller.

[Operation] As the coated core wires are processed and removed from the rotating rollers, the automatic conveying device operates to sequentially supply the coated core wire groups divided into a plurality of pieces onto the rotating rollers one by one. do. Therefore, it became possible to supply coated core wires without the need for manpower.
Tests can now be conducted smoothly and automatically without the need for a person to be present throughout.

[Example] The present invention will be described below based on the illustrated example. An embodiment of the present invention is shown in FIGS. 1 and 2. FIG. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, in conjunction with the processing of the coated core wires on the rotating roller, the coated core group 3A of the multi-pair communication cable 3 divided into a plurality of pieces is placed on the rotating roller in the test machine. An automatic conveyance device 9 was provided to supply 3A in sequence. By doing this, the test machine is able to move the coated core wire group 3A, which is made up of a plurality of multiple pieces of the multi-pair communication cable 3, while the coated core wires are not being processed on the rotating roller. With the introduction of an automatic conveying device 9 that sequentially supplies each group of coated core wires 3A, it has become possible to supply coated core wires without the need for manpower. It is possible to obtain an automatic disconnection tester for multi-pair communication cables that allows tests to be carried out smoothly and automatically even without the use of the present invention.

That is, the automatic conveyance device 9 was installed in the test machine, and the automatic conveyance device 9 was attached to a motor 9a via a support stand 9b, and the coated wire groups 3A divided into a plurality of pieces were each coated wire group. It consists of a spring 9c provided with a groove for storing every 3A. That is, the coated core wire 3B to be conveyed at the terminal of the multi-pair communication cable 3 is divided into coated core wire groups 3A each consisting of several tens of cores, and these coated core wire groups 3A each consisting of several tens of cores are placed in each groove of the spring 9c in advance. set and driven by the motor 9a, and in conjunction with the processing of the coated core wires on the rotating roller of the testing machine, several tens of coated core wire groups 3A are sequentially supplied from the groove of the spring 9c. I did it like that. In this case, in order to synchronize the supply amount from the spring 9c and the processing speed of the testing machine, a rotation speed meter is attached to the motor 9a so that the entire test can be performed at a harmonized speed. Further, the dimensions of the mounting screw holes of the support base 9b are designed so that the position of the tip of the spring 9c can be finely adjusted. By doing this, it is now possible to conduct the test without having someone accompany you the whole time.
Previously, one person operated one testing machine, but now one person can operate multiple testing machines and perform preparatory work for other frames, resulting in significant labor savings. can.

In this embodiment, the automatic conveyance device 9 has been described using a spring 9c, but it may also have a screw shape with a spiral fin, or a projection may be attached to the rotating belt to place the core wire, or the core wire may be placed on the opposing rotating belt. It is also possible to convey it by sandwiching it.

[Effects of the Invention] As described above, the present invention enables tests to be conducted smoothly and automatically even when a person is not present from beginning to end. It is possible to obtain an automatic disconnection tester for multi-pair communication cables that enables the test to be carried out.
