BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a wire band according to an embodiment of the present invention.

In the figure, the wire band 10 includes a strip plate piece 11 formed by cutting a thin metal plate into strips, and a plurality of holding portions are provided along the length direction of the strip plate piece 11. 1
2 and a locking claw 13 is formed at the end. The strip 11 has flexibility, and a metal surface is exposed on one surface, but an insulating tape 11a is attached to the other surface. In addition, the holding portion 12 is formed by raising the inner plate piece 12a which is formed by cutting out the strip plate piece 11 in a substantially U shape, and hooking the covered electric wire 20 between the raised piece 12a and the strip plate piece 11. Can be held.
The claw pieces 12a are all oriented in the same direction, that is, so as to be continuous with the strip plate piece 11 at one end side of the strip plate piece 11, and the locking claws 13 are oriented in the same direction in the strip plate piece 11. It is formed so as to cause the end tip to face the opposite end.

In the present embodiment, the wire band 10 is formed of a metal plate, but it is not necessarily a metal plate when the wires 20 are simply bundled. However,
By using the metal plate, the stripped covered electric wires 20 can be brought into contact with the exposed core wires when they are bundled so that the core wires can be connected to each other or can be connected to the shielded wire and grounded. The holding portion 12 is formed by inducing an internal claw piece 12a that is cut out in a U-shape, but is formed at least on the strip plate piece 11 and the covered electric wire 2
It suffices as long as it can hold the covered electric wires 20 so that the covered electric wires 20 do not move when they are bundled. Therefore, even if it is a mere protrusion, it is possible to prevent the covered electric wire 20 from moving so as not to loosen. However, the U-shaped cutout is used to cause the structure to be extremely simple, and as shown in FIG. 2, if the peeled covered electric wire 20 is hooked and crimped, it does not move while ensuring electrical continuity. You can also do so.

The substantially U-shape is sufficient if at least the claw piece 12a is formed on the inner side, and the chevron-shaped claw piece 12a is formed by a notch having two sides such as ">". It is also possible to form the claw piece 12a having a more complicated shape. Further, the cutout portion may not be formed in a straight line shape, but may be formed in a corrugated shape to improve the biting of the electric wire during crimping. By the way, the related nail piece 12
In the case of a, since the covered electric wire 20 is hooked from the end portion of the side where it is caused, it is easy to come off when a force that pulls back in that direction acts. Therefore, as shown in FIGS. 3 and 4, a pair of claw pieces 12a1 and 12a2, which are in the opposite direction to the direction causing the claw pieces 12a1 and 12a2, may be set and hooked on both claw pieces 12a1 and 12a2. In this way, the one claw piece 12a1
Even if the covered electric wire 20 is pulled in a direction that is easy to pull out, it is possible to prevent it from coming off in the opposite direction when it is taken by the other claw piece 12a2. Also,
By orienting the claw pieces 12a1 and 12a2 so as to open in opposite directions without overlapping, the covered electric wire 20 is bent in a crank shape and is hooked, which makes it more difficult to pull out.

Further, the holding portion 12 does not cause another piece which is cantilevered like the claw piece 12a, and as shown in FIGS. 5 and 6, the strip plate piece 11 is cut into two parallel lines. It is also possible to form a notch and form a loop portion 12b that is bent so as to bulge the portion between them into a bridge shape. in this case,
The covered electric wire 20 cannot be held by a work such as hooking on the claw piece 12a, and the covered electric wire 20 is crushed after being passed through the loop portion 12b one by one, but it can be made difficult to pull out by that amount. The locking claw 13 is formed toward the opposite end by causing the end of the strip plate piece 11 to rise, and when the strip plate piece 11 is wound, the locking claw 13 is wound on the outer peripheral side. , The locking claw 13 to the claw piece 12a
It can be hooked in the claw hole 12c that has caused. By using the claw hole 12a, it is possible to change the locking position and make the length freely. In this embodiment, the locking claws 13 are arranged so as to be caught in the claw holes 12c.
Although the holes are formed, holes may be formed individually on the strip 11 so that the locking claws 13 can be hooked. However, when the holding portion 12 is formed by the claw pieces 12a, it is not necessary to separately form a locking hole by locking the holding portion 12 in the claw hole 12c, so that the manufacturing is easy. Of course, since it may be locked at any place, the shape of the locking claw 13 and the locking position with respect to the strip plate 11 can be changed as appropriate, or a separate buckle-shaped member can be used for the end. The parts may be fixed.

Next, the operation of this embodiment having the above configuration will be described. As shown in FIG. 2, several covered electric wires 20 are hooked and held by each holding portion 12 one by one. When all the covered electric wires 20 are hooked on the holding portion 12, as shown in FIG. 7, the strip plate piece 11 is rolled up, and the locking claw 13 at the end is locked in the claw hole 12c close to the facing position. As a result, since each covered electric wire 20 is held immovably by the holding portion 12 of the strip plate 11 and is wound and fixed as a whole as a whole, it does not move and loosen in the gap portion as in the conventional case. Moreover, even when the volume of each covered electric wire 20 changes due to thermal expansion and thermal contraction, since each of the covered electric wires 20 is individually held by the holding portion 12, it does not loosen in the same manner. In addition, when the number of the covered electric wires 20 is smaller than the number of the holding portions 12, the claw holes 12c for locking the locking claws 13 are opened at appropriate intervals,
It becomes easy to lock the locking claw 13.

When the covered electric wire 20 is a shielded electric wire, the outer covering can be peeled off and hooked on the holding portion 12. Since the shielded wire is exposed in the stripped portion, the shielded wire of each covered electric wire 20 is brought into conduction through the strip plate piece 11 by bringing the shielded wire into contact with the strip plate piece 11 having an exposed metal surface so as to conduct electricity. be able to. At this time, the nail piece 1
If it is crimped with 2a, the conduction can be made more reliable, and even if a metal stay is used, the strip 1
Since the continuity is ensured with respect to No. 1, the connection resistance between the electric wires does not increase. When connecting the shield wires to each other, as shown in FIG. 8, the ends are not overlapped by being hooked by the locking claws 13, but the ends are overlapped with each other and screwed to the grounded main body to ground. You may take it. Further, as shown in FIG. 9, if the general electric wire 21 is pressure-bonded to one holding portion 12 and is wound by the locking claws 13, as shown in FIG.
The general electric wire 21 is pulled out from the bundle of 0, and the general electric wire 2
It is also possible to ground 1 by grounding it. Of course, it does not have to be a shielded electric wire, and as shown in FIG. 11, a general electric wire 21 is hooked on each holding portion 12 to be connected,
It can also be wound and used as shown in FIG.
Further, some of the electric wires are made non-conductive with the strip plate piece 11, and by peeling off some of the electric wires and hooking them on the holding portion 12,
It is also possible to join desired wires together while forming a wire bundle with the wire band 10.

As described above, the holding portion 12 that causes the claw piece 12a is formed on the strip plate piece 11, and the covered electric wire 20 is held and wound by the holding portion 12 to cover the covered electric wire in the electric wire bundle. It is possible to prevent the electric wire 20 from freely moving and loosening, and when the conductor wire of the covered electric wire 20 is brought into contact with the metal strip 11 to connect the conductor wires to each other. You can also
