Description

[Detailed explanation of the idea] This invention relates to a cord terminal processing tool.

The terminal treatment of the round cord is a distant relative of the tension-stopping of the round cord and the prevention of fraying of intervening yarns, etc. when pulling out the core wire.

However, conventionally, as shown in FIGS. 1 and 2, a ring 2 is passed through the terminal part of the round cord 1 to create an overlapping braid or an intervening yarn 3.
The method involved loosening the core wires 4 and drawing out the core wires 4, covering the ring 2 with the intervening threads 3 to form a bulge, and tying the intervening threads 3 with strings 5.

As a result, the top braid of the round cord 1 requires time and effort to unravel the intervening yarn 3 and tie it with the string 5, and the quality and performance of the terminal treatment are unstable.

Therefore, the purpose of this invention is to provide a cord end processing tool that can be easily processed and has stable quality.

An embodiment of this invention is shown in FIGS. 3 to 13.

That is, this cord terminal processing tool has three components A,
Consists of B and C.

The first structure A has a vertical semi-cylindrical recess 6 on one side thereof, a protrusion 7 serving as a protrusion and an upward claw 8 within the waist semi-cylindrical recess 6, and is split from the lower end of the semi-cylindrical recess 6. A semi-cylindrical body 10 with a groove 9 is suspended, an upward pawl 8 is formed on the inner surface thereof, a guide taper 11 is formed on the lower end of the outer surface, and a locking step 12 for preventing removal is formed on the upper part of the outer surface. ing.

Further, a pair of guide grooves 13 are formed in the upper part of the semi-cylindrical recess 6 to extend in the transverse direction.

On the other hand, a spring plate 14 is integrally extended on the opposite side surface of the first structure A, a closing locking protrusion 15 is formed on one side surface adjacent to the negative side surface, and a second and second locking protrusion 15 is formed on the other side surface adjacent to the negative side surface. Hinge parts 16 and 17 connecting the third structures B and C are integrally provided by thin wall formation.

The second and third structures B, C include a semi-cylindrical recess 6',
The semi-cylindrical body 9' and the guide groove 13' have the same structure as the first structure (hence the dash added to the numeral), and the second and third structures B and C have the semi-cylindrical recess 6'.
and a guide groove 13'.

Of these, the second component B mainly serves to sandwich the cord together with the first component A, and the third component C serves to cover the core wire together with the first component A, and is used to facilitate assembly. In order to ensure smooth operation, the cord is held between the second component B and the core wire is pulled out while the processing tool is supported by the cord, and then placed in the guide groove 13 of the first component A. In this state, the core wire is covered with the third structure C.

Then, a closing hook 18 is extended from the side opposite to the hinge portion 16 of the second structure B and is closed to the first structure A, so that the hook 18 is locked to the locking protrusion 15.

Further, the third structure C also has a hook 19 formed on the same side as the second structure B, and is secured to the protrusion by closing it to the structure A of the waist strap 1. A spring plate 20 is extended.

FIGS. 9 to 13 show the terminal processing procedure for rounded cords.

That is, FIG. 9 shows a state in which the upper end of the rounded cord 21 is housed in the inner surface of the semi-cylindrical recess 6 and the semi-cylindrical body 9 of the first structure A.

In FIG. 10, from this state, the second structure B is closed to the first structure A and the hook 18 is locked to the locking protrusion 15.

At this time, the round cord 21 is compressed and clamped within the semi-cylindrical recess 6,6' and the semi-cylindrical bodies 9, 9', and is locked and fixed by the protrusion 7 and the upward claw 8, thereby serving as a tension stopper.

In FIG. 11, in this state, the upper braid and the intervening yarn of the round cord 21 protruding from the upper part of the second structure B are removed to form a core wire 21a.

21b is exposed, bent in the horizontal direction, and placed in the guide groove 13 of the first structure A.

FIG. 12 shows a state in which the third structure C is closed to the first structure A and the hook 19 is locked to the protrusion 15.

At this time, the ends of the core wires 21a, 21b and the intervening yarn are covered and supported within the guide groove 13.

Further, in FIG. 13, this processing tool P is housed in the hooking sealing cap 22, and the semi-cylindrical body 9,
9' protrudes and is locked to the locking stages 12, 12' to prevent it from slipping out, and the inner surface of the cap 22 presses the spring plate 14.20. The closed state of the second and third structures A-C is elastically supported.

In addition, in the cap 22, 23 is a hook, and 24 is a core wire connection screw.

This configuration provides the following effects.

That is, (1) the work required for terminal processing can be simplified.

(2) The quality of terminal processing is determined by the dimensions of the parts, and has stable performance regardless of the skill level of the operator.

(3) As the round cord is compressed and clamped, the core wire is bent and guided out, so even if tension is applied to the round cord,
No force is applied to the connection part.

(4) Even against the force of twisting the cord, since the terminal processing tool P is integrated with the hooking sealing cap, rotation of the cord itself can be prevented and no force is applied to the connection part.

(5) Since the locking step 12 locks into the hole of the hook sealing cap 22, even if a pushing force is applied to the cord 21, no force is applied to the connection portion.

(6) Hook the spring plate 14.20 onto the ceiling cap 22
In order to press the inner surface of the first and third structures A
, C holds the terminal processing tool P in the closed state even more strongly, and the cord 21 is held securely.

As described above, the cord terminal processing tool of this invention holds the rounded cord between the first and second structures, and the core wire is held between the first and third structures. Since the cord is coated, it is easier to process the ends of the round cord, which has the effect of facilitating smooth work not only in the factory but also on-site.
