Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band used for binding a wire group of a wire harness, for example, when the wire group is bundled, as necessary.

[0002]

2. Description of the Related Art Conventionally, when a group of electric wires of a wire harness is converged into a band, a locking groove 3 is formed at a narrow pitch on the inner surface of a band having a band insertion locking portion 2 at its base end. A binding band 1 which is installed horizontally is used. The binding band 1 is set through a pair of band holes 4 of a protector plate 5, and a wire group 6 laid on the protector plate 5 is tightened to bind the band 1. Insert the band insertion locking part 2
A binding method of binding and fixing the wire group 6 on the protector plate 5 by inserting and locking the wire group in the protector plate 5 is adopted.

[0003]

The binding of the wire group 6 of the conventional wire harness as described above has no choice but to rely on the manual work of tightening the binding band 1 with a tool such as pliers and radio pliers, and moreover, the wire harness. In the middle of the mass production process of, since it is done successively with a fast processing tact, "variation" occurs in the tightening state of the binding band 1,
Especially in the case of weak workers such as female workers and senior workers,
Since the binding band 1 is likely to be insufficiently tightened, and the binding band 1 electric wire group 6 is also made of resin, the friction coefficient between the joint surfaces of both is small, and the two are in a state of being joined by point contact. The binding band 1 and the electric wire are likely to slip relative to each other, and the electric wire may easily slide and move due to a slight external force to disturb the binding posture, resulting in poor binding. The present invention provides a binding band that solves the above-mentioned drawbacks of the conventional techniques.

[0004]

The binding band of the present invention which solves the above technical problems is described as follows: "The band main body has a band insertion locking portion at the base end, and the tip of the band main body wound around the wire group. In a binding band in which a portion is inserted and locked in the band insertion locking portion to bind, a band-shaped slide made of a substance made of an elastic material and having a high friction coefficient is provided at a portion inside the band body and in contact with the wire group. The structure is characterized in that the stop layer is raised in the longitudinal direction of the band body. The electric wire group in the present invention includes a normal electric wire group and a group of wire rods / thin rods having a shape similar to that of the electric wire.

[0005]

Since the binding band of the present invention has the above-mentioned non-slip layer, when it is wound around the electric wire group and tightened, the anti-slip layer is thinned to the outer periphery of the electric wire group forming the group. Since they are pressed into contact with each other and elastically dented very easily to make contact with the surface of the wire group, the joining area between the two is significantly wider than the conventional binding band in which the anti-slip layer is not present,
Moreover, since the anti-slip layer has a high coefficient of friction, it is bound in a state in which relative slippage between the tightened band and the wire group in contact with the band is unlikely to occur. Therefore, even if the band tightening force is slightly insufficient, the possibility that the binding posture of the wire group is collapsed is extremely reduced, and the binding locking force of the wire group by the binding band is improved.

Embodiments will be described in detail below based on embodiments. First, referring to FIG. 1 showing a binding band 1 according to an embodiment of the present invention applied to bind a wire group 6 of a wire harness laid on a protector plate 5, a band insertion locking portion 2 is provided at a base end. Through the pair of band holes 4 formed in the protector plate 5, and the electric wire group 6 laid on the protector plate 5 between the band holes 4 is tightened to lock the band main body 10. Three
In the binding band 1 which is inserted and locked to the locking piece 14 in the band insertion locking portion 2 to bind the band, the band is raised on the inner side surface of the band body 10 at a portion in contact with the outer circumference of the wire group 6. An anti-slip layer 7 continuous in the longitudinal direction of the band is provided,
The anti-slip layer 7 is made of soft rubber having a high elastic coefficient of friction and has the same width as that of the band body 10.
(A), it is integrally bonded to the band body 10.

A binding band 1 having the above anti-slip layer 7
As shown in FIG. 1B, when the wire group 6 is tightened, and the band tip portion is inserted and locked in the band insertion locking portion 2 to be in a bound state, the wire group 6 and the slip prevention based on the tightening force. Due to the pressure contact force of the layer 7, the anti-slip layer 7 is extremely easily dented and deformed 8 and presses with a large contact area with each electric wire. Since the layer 7 exhibits a high friction state, the bundle of electric wires 6 is not likely to be easily disordered due to a normal external force expected as a wire harness.

Next, referring to FIG. 2, the band body 10
Various examples of the method of raising the anti-slip layer 7 to the above will be described. That is,
The band body 10 and the non-slip layer 7 are the same as those shown in FIG.
In addition to the adhesive fixation, the non-slip layer 7 for holding the band body 10 as shown in FIG. 2B or the non-slip layer 7 for embedding the band body 10 as shown in FIG. Alternatively, as shown in FIG. 2D, the locking projection 9 provided on the anti-slip layer 7 may be fitted into the locking hole 11 of the band body 10, or, as shown in FIG. As shown in (F), the locking projection 12 or the locking groove 1 formed on the side edge of the band body 10
3 and any of the means such as fitting the locking groove 13 or the locking projection 12 on the anti-slip layer 7 side is used. The anti-slip layer 7 may use an ethylene-propylene copolymer (EPDM) satisfying the requirements of the elastic high friction coefficient in addition to the rubber material, and further, although not shown, the surface is In some cases, the surface has a "jagged surface" to further improve the friction coefficient.

[0009]

As described above, in the binding band of the present invention, when the wire groups of the small diameter binding object are fastened and bound, the binding locking force of the binding object by the binding band is improved, It has the effect of preventing the collapse of the binding and improving the binding quality.
