Abstract

PURPOSE:To automatically drop the coating adhering to the blade through vibration of a stopper plate by vibrating the stopper plate horizontally with respect to the blade while interlocking with the open/close operation thereof. CONSTITUTION:A recess 6 matching the size of coating 19a is selected and a coated wire 19 is placed therein with the forward end thereof abutting on a stopper plate 11. When a handle part 3 is closed, the blade part 2 cuts into the coating 19a. When the coated wire 19 is drawn out under that state, the coating 19a thus cut off is pressed strongly against the blade part 2. When the handle part 3 is opened and thereby the blade part 2 opened, the interval between a screw 16 and a stop plate supporting shaft 9 increases. Consequently, a coupling wire material 14 pulls an end part 11a of the plate 11 inward thus dropping the coating 19 automatically off the blade part 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire stripper used for removing a coating of a coated wire in a uniform length.

[0002]

2. Description of the Related Art There are various types of wire strippers of this type.
The wire stripper disclosed in Japanese Patent No. 104014 is known. This wire stripper has a patch plate supporting shaft on either one of the two blade portions, and a patch plate for aligning and stripping the coating of the covered wire to a fixed length is provided on the patch plate supporting shaft. The backing plate support shaft is of a screw type so that the backing plate can be moved back and forth, whereby the length of the coating to be removed can be changed as required.

[0003]

SUMMARY OF THE INVENTION In this known technique,
The following procedure is required to cut off the coating. First, insert the coated wire into the desired recess of the blade for cutting out only the coating, and insert it until it contacts the patch plate. Then, when the blade is closed, only the coating is cut off. Next, when the coated wire is pulled out from the blade with the blade closed, only the cut coating remains on the blade. At this time, since the cross-section end surface of the cut coating is strongly attracted to the blade portion, the coating enters into the recess provided in the blade portion and the cut coating remains attached to the blade portion even if the blade portion is opened. Become. Therefore, each time the coating is cut off,
It was necessary to remove the coating cut off by hand from the blade. Therefore, an object of the present invention is to provide a wire stripper capable of automatically removing the coating remaining on the blade portion.

[0004]

In order to achieve the above object, in the wire stripper according to the present invention, one blade portion is provided with a backing plate supporting shaft, and the backing plate is swingable on the backing plate supporting shaft. The distance between the blade and the blade is changeable. Further, the other blade portion is provided with swinging means for swinging the contact plate in conjunction with the opening / closing operation of the main body.

[0005]

According to the above construction, after adjusting the position of the cover plate to the length of the cover to be cut off, the covered wire is pushed until it comes into contact with the cover plate. Then, when the handle is closed, the blades move closer to each other, and the rocking means causes the backing plate to move inward in parallel with the blade by the movement of the blades. When the blade is completely closed and the coating is cut off,
Pull out the covered wire with the blade closed. The coating cut off at this time is strongly attracted to the blade and adheres to the blade portion. However, when the blade portion is opened, the backing plate is moved outward by the swinging means in conjunction with the movement of the blade portion. Therefore, the coating adhered to the blade portion is automatically dropped from the blade portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a wire stripper 1 according to the present invention is opened and closed by a connecting pin 5 having a pair of main bodies 4 having a blade 2 at one end and a handle 3 at the other end as a fulcrum. It is freely connected, and the coated wire 19 is attached to the blade 2.
A recess 6 is provided for cutting off only the coating 19a (see FIG. 4). The recesses 6 are different in size stepwise, and can cope with different thicknesses of the covered wire. The handle portion 3 has a convex portion 7 at a position near the connecting pin 5.
Is provided, and a spring 8 that elastically springs in the opening direction of the main body 4 is provided between the convex portions 7.

A backing plate support shaft 9 is rotatably fixed to one of the blades 2a via a nut 10. The outer periphery of the backing plate support shaft 9 is a screw 9a, and the backing plate support shaft 9 is screwed with a backing plate 11 in the shape of a cutout of a rectangle. Thereby, the backing plate 11 can swing in parallel to the blade portion 2 and can change the interval with respect to the blade portion 2. The patch plate 11 is provided so as to project slightly inward from the blade 2a so that the tip of the covered wire 19 can be applied when the covered wire 19 is inserted between the blades 2. A knob 12 is provided at the tip of the backing plate support shaft 9 in order to easily rotate the backing plate support shaft 9 with a finger.
Use the pin 1 to prevent the knob 12 from rotating.
8 is fitted. A spring 13 for stabilizing the contact plate 11 is attached between the knob 12 and the contact plate 11.

Further, one end of the connecting wire 14 made of a highly elastic metal wire such as a piano wire is rotatably attached to the narrow end 11a of the contact plate 11. The other end of the connecting wire 14 is rotatably attached to a stopper plate 15, and the stopper plate 15 freely rotates around the screw 16 via a cap nut 17 on a screw 16 standing on the other blade 2b. It is possible. Therefore, in this embodiment, the connecting wire 14 corresponds to the swinging means for swinging the contact plate 11 in conjunction with the opening / closing operation of the main body 1.

Next, the operation will be described. When the backing plate support shaft 9 is rotated while holding the knob 12, the backing plate 11 moves up and down with respect to the backing plate support shaft 9 by the action of the screw.
Is adjusted to the length of the coating 19a to be cut off. The dent 6 that matches the thickness of the coating 19a is selected, the coated wire 19 is inserted, and the tip thereof is applied to the contact plate 11. Therefore handle 3
When is closed, the coated wire 19 is sandwiched by the blade portion 2 and bites into the coating 19a. When the blades 2a, 2b are closed, the distance between the screw 16 and the backing plate supporting shaft 9 is narrowed as shown in FIG. 3, and the connecting wire 14 pushes the end 11a of the backing plate 11 to the outside. The portion 11b in which the width of the backing plate 11 is widened by this operation
Moves inward.

When the coated wire 19 is pulled out as shown in FIG. 4 while maintaining this state, the cut coating 19a is strongly attracted to the blade portion 2 and adheres to the blade portion 2. When the handle 3 is opened, the blade 2 is opened by the spring force of the spring 8. At this time, the gap between the screw 16 and the backing plate support shaft 9 widens, the connecting wire 14 pulls the end 11a of the backing plate 11 inward, and this action moves the backing plate 11 outward. This patch 1
By the movement of 1, the coating 19a attached to the blade 2 is automatically dropped from the blade 2. In addition, in FIG.
Reference numeral b is a conductor wire exposed by stripping off the coating 19a.

The shape of the backing plate 11 is such that the blade 2 protrudes from the blade 2a when the blade 2 is open, and the connecting wire 14
Any shape may be used as long as it can swing around the contact plate support shaft 9 via the force received from the. Further, as the swinging means of the contact plate 11, the contact plate 11 may be rocked by an eccentric cam or the like without using the connecting wire 14. In this case, the eccentric cam is fixed to the other blade portion 2b,
The eccentric cam may be provided so that a part of the contact plate 11 is elastically contacted.

[0012]

According to the structure of the present invention, the stripping length of the coated wire is regulated by the patch plate, so that the stripping length of the coating can be kept constant at all times, and the length of cut-off of the blade is interlocked. Since the backing plate swings horizontally with respect to the blade portion, the coating adhered to the blade portion can be removed by the swinging motion of the backing plate, and it is not necessary to take it by hand one by one. Therefore, the efficiency of the work of stripping the coating of the coated wire is improved.
