Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a coated wire in the vicinity of an end of a collective coated electric wire in which a plurality of coated wires coated with conductive wires are integrated by a jacket. The present invention relates to a device used when separating and removing the residue.

<Prior Art> Since this type of collective covered electric wire has a required number of covered wires gathered together and the outer peripheral portion thereof is covered with an encapsulation means, the covered wire and the outer covering are closely adhered to each other. However, it was extremely difficult to separate and remove the outer cover. For this reason, in the past, when separating and removing this outer cover, a cut was made in the part of 10 mm or at most 20 mm from the tip part to remove it, and in 2 or 3 small steps to the required length position. It was removed by repeating this.

As another method, after making a cut in the jacket at a position where the jacket is to be removed, a vertical cut is made along the axis of the jacket part to be removed from the part where the cut is made on the tip side. A further notch was made in the shape, the outer cover was separated and cut in the longitudinal direction by the notch, and this was separated and removed by peeling it in the circumferential direction.

<Problems to be Solved by the Invention> Therefore, in order to peel and remove the outer cover of the conventional collective covered electric wire of this type, there are many methods of removing the covering in small pieces or cutting into vertical divisions and separating and cutting. However, it is necessary to take care not to cut the insulating coating of the coated wire inside, especially in the work for separating and removing the outer sheath. If this happens, the durability of the conductive wire will be deteriorated, and it will also cause a shortage of the conductive wires, so it must be absolutely avoided, so removal of the jacket requires a great deal of skill, Moreover, there is a problem that productivity is deteriorated.

Therefore, the present invention has an object to solve such a conventional problem, and in order to achieve this object, an object of the present invention is to provide a tool of a new type capable of efficiently removing the jacket. .

<Means for Solving the Problems> The structure of the assembly-coated electric wire compression tool according to the present invention for achieving the object will be described with reference to FIGS. 1 to 3 corresponding to the embodiment. The structure consists of two handle parts (12), (13) extended to one side via a pivot (11),
From the two action parts (14) and (15) whose relative spacing (s) moves wide and narrow by the operation of these handle parts (12) and (13), and the tips of these action parts (14) and (15). Shafts (16) and (17) implanted in a direction that intersects with the wide and narrow movement direction on one side at a position slightly separated from the handles (12) and (13), and these shafts (16) and (17). ) Rotatably mounted on each of the rotating rollers (18), (19) as an electric wire pressing member having a concave groove in the outer peripheral portion, and the above-mentioned action of holding the jacket (3) of the covered electric wire (A). The structure is composed of the tips of the parts (14) and (15).

<Operation> Since the present invention has such a configuration, the outer peripheral portion of the jacket portion to be removed before peeling the jacket (3) of the collective covered electric wire (A) is Adhesion between the jacket (3) and the covered wire (2) by inserting and sandwiching between the wire clamps (18), (19) in the tool to clamp the covered wire (A) from the outside. By loosening the adhesion between the two (2) and (3), the outer cover (3) can be easily removed, and the tips of the action parts (14) and (15) can be removed. The outer cover (3) of the covered electric wire (A) is clamped and removed by.

<Examples> Examples of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 are views showing an embodiment of a compression tool of the present invention. The compression tool (B) is composed of two metal rod-shaped members such as pliers or pliers, and a pivot shaft (11 ) Two handle parts (12), (13) extended to one side, and two actions that the relative interval (s) moves wide and narrow by the wide and narrow operation of these handle parts (12), (13). Part (14), (15) and one side of these action parts (14), (15) at a position slightly away from the tip orthogonal to the wide and narrow movement direction to the handle part (12), (13) side Two shafts (16) and (17) that are screwed in the same direction, and a concave groove is rotatably mounted on each of these two shafts (16) and (17). Rotating roller (1
It consists of 8) and (19).

Using the wire compression tool (B) with such a structure,
The end of the collective covered electric wire (A) in which a large number of covered wires (2) covering the conductive wire (1) are integrated by the jacket (3) as shown in the cross-sectional shape in Figs. In order to use the nearby jacket (3) to separate and remove the covered wire (2) ..., first, at the position (4) where the jacket (3) is to be separated and removed, the collective covered wire (A) is used. Make a notch (6) in the jacket (3) from the entire circumference of the outer peripheral surface of the and then position deeper than the notch (6) position (left side position in FIG. 4)
Is inserted between the two rotating rollers (18) and (19) as electric wire pressing bodies in the compression tool (B), and the two handle parts (12) and (13) are grasped in the closing direction. As shown in FIG. 2, the clamp tool is clamped, and the compression tool (B) is moved in the direction of the arrow (a) in the figure while maintaining the clamped state, and the cable (A) is moved. Axial (3) along the axial direction up to the tip (5) of
And then using the compression tool (B) itself,
As illustrated in FIG. 4, at the tips of the action portions (14) and (15), the outer sheath (3) is formed in the same manner as in the case of using the conventionally known pinching tool (C) such as pliers. ) And pull it toward the tip (5) side of the electric wire (A) to cover the sheath (3 ′) on the tip (5) side from the portion where the cut (6) is made, the covered wire (2) ... It is separated and removed from.

When removing the outer cover (3 '), the outer cover is set as described above.
Instead of pinching the jacket (3) after inserting the notch (6) in (3), press the jacket (3) before inserting the notch (6), and then cut the notch (6). Put and coat as above
(3 ') may be removed by sandwiching.

FIG. 7 shows a state in which the jacket (3 ') having the required length is removed in this manner.

After removing the jacket (3 ') in this way, as shown in FIG. 8, the coating on each individual coated wire (2) ... As shown in Fig. 9, connect the terminals (t) etc. to each conductive wire (1) with the coating removed, and connect the conductive wire (1) to a connector.
It is connected to (c) etc.

<Effects of the Invention> As is apparent from the above description, the collective electric wire compression tool according to the present invention is such that the outer cover of the collective covered electric wire is in close contact with the covering of the inner covered covered wire, and a nerve corresponding to its removal is provided. Focusing on the current situation that requires time and skill,
When removing this jacket, arrange the tool and the coated wire on the same line, and pinch the coated wire from both sides in a point contact manner to move it in the longitudinal direction to ensure the adhesion between the jacket and the inner coated wire. Since it is designed to loosen the degree of adhesion between the two, it is extremely efficient to separate the jacket from the interior coating wire with extremely simple means of pressurizing the jacket from the outside and pulling it in the axial direction. It can be done easily and easily, and without using any other tool, the tip of the action part can immediately hold and pull out the jacket of the covered electric wire,
It has come to be possible to expect a remarkable effect that the jacket can be removed very easily and quickly.
