DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-shrinkable film-wrapped bundled electric wire in which a bundle of electric wires wound in a ring shape is bound by a binding band and then wrapped with a heat-shrinkable film.

[0002]

2. Description of the Related Art Wiring for homes, buildings, factories, etc.
Although electric wires and VVF electric wires are used, these electric wires are generally used in the form of a bundled wire wound in a ring shape and bundled for ease of storage, transportation, handling and the like during use. I have. Most of the bundled electric wires wound in a ring shape are wrapped in order to protect the electric wires during storage and transport and to prevent the bundle from being broken, and are wound in a ring shape as a wrapping means. It is known that a wire bundle is covered and packaged with a heat-shrinkable film in the form of a sleeve.

FIG. 3 shows a bundled electric wire wrapped with a conventionally known sleeve-shaped heat-shrinkable film. A bundle of electric wires 10 wound into a ring and a binding band 11 are shown.
Is stretched from the inner peripheral side to the outer peripheral side of the electric wire 10, and both ends 12, 13 are overlapped on the outer peripheral side of the electric wire bundle 10, fused and fixed, and covered with a sleeve-shaped heat-shrinkable film 15 from above. Packaged.

[0004]

However, according to the above-mentioned heat-shrinkable film-wrapped wire bundle, the binding band 11 for binding the wire bundle 10 wound in a ring shape is moved from the inner peripheral side to the outer peripheral side of the wire bundle 10. Since the wire bundle 10 is bridged and both ends 12 and 13 are overlapped on the outer peripheral side of the wire bundle 10 and fixed by fusion, there are the following problems.

In many cases, the heat shrinkable film 15 for covering and wrapping the wire bundle 10 is transparent or translucent. In this case, both ends 12, 13 of the binding band 11 are overlapped through the heat shrinkable film 15 and melted. The fixed portion is visible, and the fusion fixing portion 14 of the binding band 11 is thicker because both ends 12, 13 of the binding band 11 are overlapped with each other, so that the portions 12, 13 protrude. As a result, the heat shrinkable film 15 is pushed outward, so that the appearance of the product is poor.

As described above, the overlapping end portions 12, 13 for fusing and fixing the binding band 11 protrude and push the heat-shrinkable film 15 to the outside, so that the bundled bundled wire is At the time of storage or transportation, there is a possibility that the portion protruding outward rubs against the protruding portion of another bundled bundled wire or a nearby object, and the heat shrinkable film 15 in the same portion is broken.

In order to release the binding of the wire bundle 10 when using the wires, a tool such as a cutter for cutting the binding band 11 is required.

[0008] It is an object of the present invention to provide a heat-shrinkable film-wrapped bundled electric wire which improves the appearance of the product and the ease of handling during storage, transportation and use of the electric wire.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a binding band is laid over a wire bundle wound in a ring shape, and both ends of the binding band are overlapped and fused. A heat-shrinkable film wrapped bundle wire fixed and covered from above with a sleeve-shaped heat-shrinkable film, wherein the binding band is extended from the outer side to the inner side of the wire bundle, and both ends of the wire are wound. It is characterized in that the bundles are superposed and fused and fixed on the inner peripheral side. As described above, the binding band is bridged from the outer peripheral side to the inner peripheral side of the wire bundle, and both ends thereof are overlapped and fixed by fusion on the inner peripheral side of the wire bundle. The appearance of the product is better than that of a conventional heat-shrinkable film packaged bundle wound wire in which the wire bundle is fused and fixed at the outer periphery and the portion protrudes outward, and the protrusions at both ends of the fusion-fixed binding band are reduced. During storage and transport, the protruding portion of the conventional heat-shrinkable film packaged bundle wound wire collides with another projecting portion of the heat-shrinkable film bundle wound wire or an object in the vicinity so that the heat-shrinkable film of the same portion does not exist. There is no danger that it will be broken. Furthermore, when unbinding the wire bundle when using the electric wire, the fusion fixing portion of the binding band that binds the wire bundle is exposed on the inner periphery of the wire bundle. By peeling off, the binding of the electric wire bundle by the binding band can be released without using a tool such as a cutter.

According to the second aspect of the present invention, the fusion bonding at both ends of the binding band bridged over the wire bundle leaves an unfused portion having a predetermined length L from at least the end of the end overlapped outside. It is characterized by being fused. By doing so, at the time of using the electric wire, when unbonding the wire bundle by peeling off the fusion fixing portion of the binding band, by grasping the unfused portion at the end of the binding band stacked outside. , Can be easily peeled off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a heat-shrinkable film-wrapped bundled electric wire according to the present invention will be described below in detail with reference to FIGS.

In FIG. 1, reference numeral 1 denotes an electric wire bundle obtained by winding and bundling an IV electric wire, a VVF electric wire or the like in a ring shape;
Is a binding band made of resin, and PE, PP, P
VC, PET, etc. are used.

The binding band 2 is extended from the outer peripheral side to the inner peripheral side of the wire bundle 1 wound and bundled in a ring shape, and both ends 3 and 4 are overlapped on the inner peripheral side of the wire bundle 1. It is fixed by fusion. The fusion of the ends 3 and 4 of the binding band 2 binds the wire bundle 1 so as not to collapse,
Further, the fusion fixing portion 5 is fusion-fixed with such an adhesive strength that it can be peeled off by hand.

Further, in this embodiment, the ends 3 and 4 of the binding band 2 are fused by leaving an unfused portion 6 of a predetermined length L from the end of the end 3 which is overlapped outside. I have.

Although the length L of the unfused portion 6 is not particularly limited, it is preferable that the length L is such that it can be easily grasped by hand.

Reference numeral 7 denotes a sleeve-shaped heat-shrinkable film in which the surface of the ring-shaped wire bundle 1 bound by the binding band 2 is covered from above the binding band 2 and wrapped, and is opened at the center of the wire bundle 1. An opening 9 communicating with the hole 8 is opened and covered and packaged.

From the above configuration, since both ends 3 and 4 of the binding band 2 are overlapped and fixed by fusion on the inner peripheral side of the wire bundle 1, both ends 1 and 2 of the binding band 11 shown in FIG.
2 and 13 are fused and fixed on the outer peripheral side of the wire bundle 10.
As compared with the conventional heat-shrinkable film-wrapped bundled wire in which 2, 3 protrude outside, the appearance of the product is good, and there is no protrusion of the fusion-fixed binding band 2, so that during storage and transport, In this case, there is no possibility that the heat-shrinkable film 15 in the same portion may be broken due to the protrusion of the heat-shrinkable film-wrapped wire or the nearby object.

Further, when the electric wire bundle 1 is untied when the electric wire is used, the fusion fixing portion 5 of the binding band 2 for binding the electric wire bundle 1 passes through the opening 9 of the heat shrinkable film 7 to form the hole of the electric wire bundle 1. 8, the hand is inserted into the hole 8 of the wire bundle 1 through the opening 9, the fusion fixing portion 5 is peeled off, and both ends 3, 4 of the binding band 2 are separated. Thus, the binding of the wire bundle 1 by the binding band 2 can be released.

At this time, in this embodiment, the fusion of the both ends 3 and 4 of the binding band 2 is
Since the unfused portion 6 having a predetermined length L is fused from the end of the end portion 3 overlapped on the outside, the unfused portion 6 is gripped when the fused fixing portion 5 is peeled off. By pulling, the fusion fixing portion 5 can be easily peeled off.

[0020]

As described above, according to the heat-shrinkable film-wrapped wire according to the present invention, the appearance of the product is good and the handling is easy, and further, when the wire bundle is unbound by the binding band when using the wire, There is an effect that it can be easily unraveled without requiring a tool such as a cutter.
