Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheathing stripping device for a covered electric wire, which is particularly suitable for stripping a sheathing portion in the middle of a sheathed electric wire.

Conventionally, there has been a device called a wire stripper for stripping the covering portion of a covered electric wire.

Its structure is such that the tips of a pair of handles are pivotally connected, and a movable force that can collide with a fixed blade is pivotally attached to each tip of the pair of handles via a link. In addition, how to use it is to insert the coated wire between the movable blade and the fixed blade, and then squeeze the handle to lower the movable blade through the link and cut the coated part. As the cutting occurs, a pair of left and right movable blades and a fixed blade are opened in the left and right direction, thereby separating the cut covering portion from the conductor portion.

Therefore, when the above-mentioned wire stripper cuts off the sheathing part from the end of the insulated electric wire, it can be done by just grasping the handle, but when cutting off the sheathing part at the middle part of the insulated electric wire, it can be done in one pair. The coating is removed from the conductor by making incisions in two places with a movable blade and a fixed blade in accordance with the width to be stripped, and then using a cutter or the like to cut between the two incisions. must be stripped away.

Therefore, it requires three operations, which takes time and effort to peel off the coating, and it also requires a process of cutting the coating in the axial direction using a cutter, etc. It was dangerous.

The present invention has been made in view of the above-mentioned points, and its purpose is to provide a method that is particularly suitable for cutting off the sheathing in the middle part of a covered electric wire, and that the work of cutting off the sheathing can be done quickly and safely. An object of the present invention is to provide a device for stripping a covering portion of a covered electric wire.

Hereinafter, an embodiment will be described in which the invention is illustrated in the drawings.

At the same time, the upper end 16b of the operating rod 16 is engaged in a hole 11a inserted into the lower surface of the sliding plate 11 through a long hole 1b drilled in the base 1.

By pivoting the lever 14, the shaft portion 14a is pivoted, thereby pivoting the operating rod 16 about the mounting boss 15, so that the upper end 16b of the sliding plate is engaged in the hole 11a. 11 is slid back and forth on the base 1 within the guide plate 10° 10, so that the actuating plate 6 is moved forward or backward.

However, as another means for advancing or retracting the actuating plate 6, as shown in FIG. 7, the actuating rod 16' is extended below the pivot point of the shaft 50 to form a substantially dogleg shape. A foot-operated type may be used in which the pedal 52 and the operating rod 16' are connected via a link 51 whose upper end is pivotally connected to the extending end 16'a of the operating rod 16'. and the operating rod 16' is connected to the shaft 50 via the link 51.
The actuating plate 6 is moved forward by pivoting around the base 1, and when the rear part of the peckle 52 is pushed down, the link 51 and the actuating rod 16' pivot to return to their original positions, so the actuating plate 6 moves forward from the base 1. Retreat above the area and return to the old position.

Alternatively, the actuating plate 6 may be moved forward or backward using a motor, sprocket, chain, or the like.

Further, the contact surfaces between the guide plates 10, 10 and the sliding plate 11 are formed into a dovetail groove shape so that the sliding plate 11 does not come out when sliding freely forward and backward between the guide plates io, io.

Reference numeral 17 denotes a sliding blade that slides in a long hole 18 bored at the boundary between the anti-slip thread 3 and the stopper plate 4. This is for cutting in the axial direction between the cuts T1 and T2 made around the covering portion 2b.

As a means for sliding the sliding blade 17, a sliding plate 20 is slidably inserted between two guide plates 19° 19 fixed to the upper and lower sides of the base 1, and this sliding plate 20 and a presser plate 21 fixed to the sliding plate 20, the sliding blade 17 is inserted so as to be movable up and down, and the lever 23 whose lower end is pivoted to the base 1 with a pin 22 is attached. By pivoting,
The sliding plate 20, which is pivotally connected to this lever 23 via a link 24, is slid within the guide plate 19.19, thereby causing the sliding blade 17 to slide.

The degree of exposure from 8 is adjusted depending on the thickness of the covering portion 2b to be cut.

One embodiment of the present invention has the above-mentioned configuration, and the operation of stripping the sheathing portion of the sheathed wire will be explained below in the order of steps.

First, the covered electric wire 2 is placed on the anti-slip thread 3 of the base 1.

When the lever 14 is then pivoted, both the shaft portion 14a and the attachment boss 15 rotate, so that the operating rod 16 whose lower end portion 16a is fitted onto the attachment boss 15 pivots.

Therefore, the sliding plate 11 whose upper end 16b is engaged in the hole 11a slides forward on the upper surface of the base 1 while being guided by the guide plates 10, 10.

Therefore, the sliding plate 11 is inserted through several backing materials 12.
An actuating plate 6 screwed to moves above the base 1 to the left in FIG.

When the actuating plate 6 is further moved by pivoting and tilting the lever 14, the covered electric wire 2 placed on the upper surface of the anti-slip thread 3 of the base 1 is attached to the lower surface of the tip of the actuating plate 6 by the bolt 7.
The mounting member 8 is rotated until it comes into contact with the stopper plate 4 by being pressed by the biting strip 8c of the mounting member 8 screwed at the
The peripheral cutting blades 5, 5 attached to the mounting member 8 cut two cuts T1. T2 is inserted.

In this case, the height from the base 1 to the peripheral cutting blade 5.5 can be easily adjusted by adjusting the number of backing materials 12 interposed between the sliding plate 11 and the actuating plate 6. ,
Even if there is a difference in the thickness of the covering part 2b, only the covering part 2b can be easily cut.

After that, when the lever 23 is pulled, the sliding plate 20 is pulled through the link 24, so that the sliding blade 17 inserted between the sliding plate 20 and the holding plate 21 slides on the sliding plate 20. It slides inside the elongated hole 18 along with the movement.

Therefore, the covering portion 2b has two cuts T1. A cut T3 is made in the axial direction between T2 and the cut is made.

Finally, when the lever 14 is pivoted to the original position and the actuating plate 6 is moved backward, the cut covering portion 2b into which the many biting stripes 8c are biting is moved back as the actuating plate 6 is moved back. Since it is rotated by the attachment member 8, it is peeled off from the conductor portion 2a.

In this way, the peeling operation of the covering portion 2b of the covered electric wire 2 is completed.

As described above, the present invention advances the circumferential cutting blades arranged in parallel in a direction perpendicular to the covered wire to make two cuts of a predetermined length around the covered portion, and then slides the wire in the axial direction of the covered wire. By sliding the movable blade, it is possible to quickly cut between the two notches in two operations, and since no cutter or the like is used, the coating can be removed safely without hurting the hands. Suitable for peeling off the coating in the middle of a covered wire.
