[Processing procedure for the end of the shielded wire and crimping process using the terminal]
Hereinafter, the processing procedure of the terminal portion of the shielded electric wire 1 will be described with reference to FIG. First, as shown in FIG. 3A, the insulating sheath 2 at the terminal portion of the shielded electric wire 1 is cut and removed to a predetermined length. This exposes one end of the braided wire 3.

Next, as shown in FIG. 3B, the sleeve 6 is fitted from the tip end side of the exposed braided wire 3 to the vicinity of the end edge of the insulating sheath 2. At this time, since the inner diameter of the sleeve 6 is set to be larger than the outer diameter of the braided wire 3, the sleeve 6 can be fitted and inserted into the outer peripheral surface of the braided wire 3 relatively smoothly. After that, the sleeve 6 can be crimped from the outside with an appropriate force using a jig. As a result, the sleeve 6 is positioned and fixed on the outer circumference of the braided wire 3.

Next, as shown in FIG. 3C, the tip portion 3a of the exposed braided wire 3 is bent back in the insulating sheath 2 direction and covered with the outer peripheral surface of the sleeve 6.

Subsequently, as shown in FIG. 3D, the tip portion of the exposed insulator 4 is cut and removed to expose the core wire 5 to a predetermined length. As a result, as shown in FIG. 1, the end portion of the shielded electric wire 1 is in a state where the core wire 5, the insulator 4, and the braided wire 3 covered with the sleeve 6 are exposed to a predetermined length.

Next, a procedure for crimping the terminal portion of the shielded electric wire 1 to the barrel portion 13 of the terminal 10 will be described.

First, the terminal portion of the shielded electric wire 1 is inserted into the inside from the opening side of the barrel portion 13 of the terminal 10 to perform axial positioning.

That is, as shown in FIG. 5A, the exposed braided wire 3 (sleeve 6) of the shielded electric wire 1 is arranged between the first and second barrel pieces 15 and 16.

At this time, the end portion of the insulating sheath 2 is arranged between the third and fourth barrel pieces 17 and 18. Further, the locking claws 19 and 20 are arranged at positions facing the annular groove between the end portion of the insulating sheath 2 and the braided wire 3.

Then, in this state, the first to fourth barrel pieces 15 to 18 of the barrel portion 13 of the terminal 10 placed on the base are pressed together from above by a crimping crimper (not shown) and crimped. Then, as shown in FIGS. 4 and 5B, the third and fourth barrel pieces 17 and 18 crimp the outer peripheral portion of the insulating sheath 2 from above, and the tip portions 17a and 18a that are rolled inward and deformed are insulated. It bites into the outer peripheral portion of the sheath 2 and is crimped.

On the other hand, the first and second barrel pieces 15 and 16 crimp the tip portion 3a (outer peripheral portion) folded outward of the braided wire 3 and the sleeve 6 and the inner peripheral portion 3b together, and crimp these. Along with this, the insulator 4 is also crimped at the same time.

At this time, as shown in FIG. 5B, each of the locking claws 19 and 20 has the inner end edges 19c and 20c of the tip portions 19b and 20b in contact with the rear end edge 6a of the sleeve 6 and the outer end edge 19d. , 20d is crimped to the outer peripheral portion of the insulator 4 so as to bite into the outer peripheral portion.

As described above, in the present embodiment, the third and fourth barrel pieces 17 and 18 of the barrel portion 13 are crimped and bite into the outer peripheral portion of the insulating sheath 2, and the first and second barrel pieces 15 and 16 are sleeves. Since the inner peripheral portion of the braided wire 3 is crimped through the braided wire 3, a strong connection can be obtained.

In particular, in the present embodiment, the inner end edges 19c and 20c of the locking claws 19 and 20 come into contact with the rear end edges 6a of the sleeve 6 via the groove portions 14c and 14d, and thus serve as a stopper for the sleeve 6. Demonstrate function. Therefore, the sleeve 6 is restricted from shifting (moving) in the insulating sheath 2 direction together with the braided wire 3. Further, since each of the locking claws 19 and 20 abuts on the rear end edge 6a of the sleeve 6 and at the same time the front end edge 6b on the opposite side abuts on the bent portion, the direction opposite to the insulating sheath 2 of the sleeve 6 The deviation to is also regulated. Therefore, a stronger connecting force between the terminal 10 and the braided wire 3 and the insulator 4 can be obtained.

Moreover, since the outer end edges 19d and 20d of the tip portions 19b and 20b of the locking claws 19 and 20 directly bite into the outer peripheral portion of the insulator 4, the connection force with the insulator 4 is further high. Become.

Therefore, the connection strength of the terminal 10 with respect to the entire terminal portion of the shielded electric wire 1 is significantly improved.

Further, when the first barrel piece 15 and the second barrel piece 16 are pressurized, the respective protrusions 15b and the fitting groove 16b are fitted, and the shoulder portions 15c and 15c and the fitting protrusions 16c are fitted to each other. , 16c mesh with each other. Therefore, a strong bond between the two 15 and 16 can be obtained, and a strong crimping force to the braided wire 3 and the sleeve 6 can be obtained. As a result, the connection strength between the shielded electric wire 1 and the terminal 10 is further increased.

Further, in the present embodiment, since only the locking claws 19 and 20 for holding the sleeve 6 from the axial direction are provided, the structure is simplified and the manufacturing workability is improved. Further, since the shaft end of the sleeve 6 is only held by the locking claws 19 and 20 together with the caulking of each barrel piece 15 to 18, the man-hours for connecting to the terminal 10 are not increased and are the same as usual. Therefore, the decrease in connection work efficiency can be suppressed.

In Japanese Patent Application Laid-Open No. 2007-294238 previously filed by the present applicant, a sleeve is passed through the outer circumference of the braided wire, and the sleeve is pressed with a uniform force over the entire circumference to be brought into close contact with the braided wire. Although the techniques are also disclosed, these merely aim at the adhesion between the braided wire and the sleeve, and are completely different from the connection structure using the locking claws 19 and 20 as in the present embodiment. .. Therefore, the operation and effect of the present embodiment cannot be achieved from any of the above-mentioned prior arts.
[Second Embodiment]
FIG. 6 shows a second embodiment of the present invention, and the basic structure is the same as that of the first embodiment, except that an annular stopper which is a locking groove on the insulating sheath 2 side of the outer peripheral surface of the sleeve 6 is different. The groove 7 is formed.

The stopper groove 7 is formed by crushing the outer peripheral surface of the sleeve 6 with, for example, a press molding machine, and the annular protrusion 7a is embossed on the inner peripheral side by this crushing process.

As shown in FIG. 3C, the stopper groove 7 is also covered by the tip portion 3a when the tip portion 3a of the braided wire 3 is folded back to cover the outer peripheral surface of the sleeve 6.

On the other hand, the locking claws 19 and 20 of the first and second barrels 15 and 16 have the same structure as those of the first embodiment, and the locking claws 19 and 20 of the first and second barrels 15 and 16 have the same structure as those of the first embodiment. At the time of caulking, the braided wire 3 is locked in the stopper groove 7 via the bent end portion 3a.

Hereinafter, the caulking process of the terminal 10 will be briefly described based on FIGS. 6A and 6B.

Since the arrangement of the shielded electric wire 1 on the terminal 10 which is a premise of caulking is the same as that of the first embodiment, the description thereof will be omitted.

The first to fourth barrel pieces 15 to 18 of the barrel portion 13 of the terminal 10 placed on the base are pressed from above by a crimping crimper (not shown). Then, as shown in FIGS. 4 and 6B, the third and fourth barrel pieces 17 and 18 crimp the outer peripheral portion of the insulating sheath 2 from above, and the tip portions 17a and 18a that are rolled inward and deformed are insulated. It bites into the outer peripheral portion of the sheath 2 and is crimped.

At the same time, the first and second barrel pieces 15 and 16 crimp the tip portion 3a (outer peripheral portion) of the outer braided wire 3 together with the sleeve 6 and the inner peripheral portion 3b, and the insulator is attached to these crimps. 4 is also crimped at the same time.

At this time, as shown in the figure, each of the locking claws 19 and 20 has its tip portions 19b and 20b entering the inside of the stopper groove 7 via the tip portion 3a (outer peripheral portion) of the braided wire 3. It abuts on the bottom surface of the stopper groove 7. Then, the inner end edges 19c and 20c of the respective tip portions 19b and 20b abut on one inner side surface 7b of the stopper groove 7 of the sleeve 6, and the outer end edges 19d and 20d pass through the tip portion 3a of the braided wire 3. Press against the bottom surface of the stopper groove 7.

The tip portions 19b and 20b of the locking claws 19 and 20 at the time of caulking either break through the mesh of the braided wire 3 in the stopper groove 7 or press the braided wire 3 against the bottom surface of the stopper groove 7 as it is. ing.

In this way, as in the first embodiment, the third and fourth barrel pieces 17 and 18 are crimped and bite into the outer peripheral portion of the insulating sheath 2, and the first and second barrel pieces 15 and 16 hold the sleeve 6. Since the inner peripheral portion of the braided wire 3 is crimped through the braided wire 3, a strong connection can be obtained.

Further, in the present embodiment, the inner end edges 19c and 20c of the locking claws 19 and 20 abut on the rear end edges 6a of the sleeve 6 via the groove portions 14c and 14d to function as stoppers for the braided wire 3. At the same time, the axial deviation (movement) in the two directions of the insulating sheath is regulated.

In particular, at the same time as caulking, the outer end edges 19d and 20d of the tip portions 19b and 20b of the locking claws 19 and 20 press against the bottom surface of the stopper groove 7 to press the protrusion 7a of the sleeve 6 inward. .. Therefore, since the protrusion 7a is strongly pressed against the outer peripheral portion of the insulator 4, the connecting force with the insulator 4 is also increased. Therefore, the connection strength between the terminal portion of the shielded electric wire 1 and the terminal 10 is significantly improved.

The present invention is not limited to the configuration of the embodiment, and for example, the number of the locking claws 19 and 20 may be two or more. Further, the locking portion may be formed in an arc shape instead of a claw shape.

Further, the braided wire 3 can be formed to have substantially the same length as the axial length of the sleeve 6 without bending the tip portion 3a in a folded shape.

It is also possible to provide two stopper grooves 7 at positions corresponding to the two locking claws 19 and 20 instead of an annular shape, and two more depending on the number of two or more locking claws. It is also possible to form the above.

Further, the number of each barrel 15 to 18 can be increased or decreased according to the specifications and size of the connector and the terminal 10, and the width in each axial direction can also be arbitrarily changed. ..
