JPS587764Y2 - Automatic/manual cable wrapping device for single-core cable head - Google Patents

Description

[Detailed description of the invention] This invention not only allows the cable to be inserted into the single-core cable head easily and reliably using electric power without requiring the conventional method to obtain cables, but also when there is a power outage or The object of the present invention is to provide a cable insertion device that can be easily inserted manually in locations where there is no power supply.

Conventionally, it was necessary to manually insert a cable into a single-core cable head.

The insertion requires approximately 150 to 20 meters of force, which not only requires the hands of two or three people and a lot of time, but also makes it difficult to check whether the cable has been inserted to the required depth. There were also defects of incomplete insertion as it was not always easy to confirm.

This invention not only eliminates the above-mentioned conventional defects by using an electric motor to insert the cable, but also allows the cable to be easily inserted by switching to the handle operation even in the event of a power outage or in a place where there is no power supply equipment. It is about giving what you get.

The present invention will be explained with reference to the drawings.

In the figure, 1 is an insulator with a single core cable head, and 2 is the insulator 1.
3 is a cable, and 4 is a cable insertion part 5 coated with nylon or the like with the outer sheath removed for insertion into the insulator, and the core wire at its tip connects to this insertion part 4. The core wire 5 is closely inserted into the insulator 1, and the tip end surface a of the core wire is inserted deep into the compression terminal 2, and the above is the same as the conventional method.

6 is the base of the first child, and the base 6 has a clamp support plate I in the center, a fixing plate 8 on the front side, and a cable support plate 9 on the rear side.
A clamp 10 for cable clamping is installed on the top of the clamp support plate, a cable support roller 11 is installed on the head of the cable support plate 90, and a movable plate 12 is installed vertically in front of the base 6. Then, the insulator 1 is stably fixed on the head thereof, and the first screw shaft 14 having a screw 13 carved in the central part of the movable plate 12 is fitted at its tip 14 so as to be rotatable. The screw shaft 14 extends rearward (to the right in FIG. 1), passes through the center of the fixed plate 8, and extends rearward, and guide rods 15, 15 are provided above and below the movable plate 12. A motor mounting plate 16 is fixed and vertically fixed to the rear end of these screw shafts 14 and guide rods 15 and 15 by passing through the top and bottom of the fixed plate 8 and extending rearward, and a motor M is mounted on the back side thereof. In this case, the rotation axis 1 of the motor
7 and the rear end of the screw shaft 14.
8 are combined.

In contrast to the above-described structure, the present invention has a through hole 19 formed in the center of the fixed plate 8, and a rotary type nand 21 having an internal thread 20 carved on the inner surface of the through hole 19, which is rotated without moving from side to side. The above-mentioned screw shaft 14 is freely fitted into the rotating Nand 21.
The inner thread 20 of the nut and the thread 13 of the shaft are screwed together by screwing them together, and the worm gear 22 is loosely inserted into the screw shaft 14, and the gear 22 is moved to the back of the NAND 21, that is, to the right side in the figure. The worm gear 22 and the NAND 21 are integrally connected by means of the gear 22, and a rotation operating shaft 23 is located at the center of the fixed plate 8, slightly higher than the screw shaft 14. Bearing 24.24
The worm 25 is mounted on the shaft, and the worm 25 is meshed with the worm gear 22, and a handle 26 is attached to the protruding end of the operating shaft 230.

27 is a handle of the clamp 28 is a fitting hole for fitting an insulator recessed in the head of the moving plate 29 is a free passage hole 30 of the motor mounting plate
A motor movement mechanism 31, a limit switch 32, a limit contact piece 33, a compression tool holder 34, and an insulator tightening band.

In order to rotate the motor in forward and reverse directions, a forward switch and a reverse switch are installed, but they are omitted from illustration.

Since the present invention is configured as described above, if power is currently being supplied as usual, the motor M is activated to insert the cable.

That is, as shown in FIG. 1, the cable head insulator 1 is tightened onto the movable plate 12, the cable 3 is fixed to the clamp 10, the core wire 5 and the cable insertion part 4 are opposed to the insulator 1, and the movable plate 12 is branched out forward. When the motor M is rotated in the reverse direction by the operation of the reverse switch, the screw shaft 14 rotates in the reverse direction f.

In this case (7), the nut 21 is connected to a gear 22, and the gear 22 meshes with a series of continuous mechanisms consisting of a handle 26, an operating shaft 23, and a worm 25, so that the screw shaft 14
When the nut 21 rotates in the opposite direction, the nut 21 exists as a fixed nut, so the screw shaft 14 rotates and retreats, forcing the cable insertion parts 4 and 5 into the insulator as shown in FIG. Since the terminal 2 is inserted into a predetermined depth, the work is completed by compressing the terminal 2 using a compression tool.

Furthermore, since the safety flange 18 operates when the cable insertion is completed, no harm is caused to the motor M.

When the work is completed, the cable head 1 and cable 3 are removed, and when the motor M is rotated in the normal direction by operating the forward switch, the NAND 21 exists as a fixed NAND as described above, so only the screw shaft 14 is rotated in the normal direction and the movable plate is rotated. 12 is moved forward to return to the cable insertion starting state as shown in the first figure, and the cable insertion work is performed again.

If the power supply has stopped or if you are working in a place where full heat power cannot be supplied, operate the handle 26 as shown in FIG. 1 to reverse the rotation of the gear 22 and move the screw shaft 14 backward.

That is, in this case, the threaded shaft 14 remains stably stationary due to the weight support of the motor M, so the rotation of the handle 26 causes the nut 21 to rotate as a rotating nand, and therefore the threaded shaft 14 in a stationary state moves back, as described above. Similarly, the cable insertion work can be carried out, and conversely, in Figure 2, after removing the completed cable and insulator, the handle 26
By rotating the NAND 21 in the normal direction, the NAND 21 can be rotated as a rotating NAND, and the movable plate 12 can be returned to its original position by advancing the screw shaft 14.

As described above, according to the present invention, if there is power supply, the cable can be semi-automatically inserted into the cable head very easily and reliably using the motor.
In the event of a power outage or in a place where there is no power supply at all, you can switch to the 11 handle operation and easily insert the cable manually, which provides great convenience and effectiveness in the cable insertion work. It is an idea.
