Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a band clamp for binding and fixing long members such as a wire harness.

[0002]

[Prior art]

 7A to 7C show an example of a conventional band clamp (see Japanese Utility Model Laid-Open No. 50-24588).

This band clamp includes a clamp body 1 and a flexible band portion 2 extending from the clamp body 1. The clamp body 1 has an insertion hole 3 into which the band portion 2 is inserted. Has been done. A flexible check claw 4 is provided in the insertion hole 3, and a recess 5 that engages with the check claw 4 is continuously provided in multiple stages on the surface of the band portion 2.

The clamp body 1 is provided with a support portion 6 for supporting a single or a plurality of electric wires 7 as long members. The support portion 6 has a protrusion 8 for pressing the electric wires 7 when the electric wires are bundled. It is extended in the direction intersecting with.

When the band portion 2 is wound around the electric wire 7 and then inserted into the insertion hole 3 and pulled, the check claw 4 engages with the concave portion 5 and the electric wire 7 is bound and fixed to the support portion 6. It At this time, the electric wire 7 is pressed by the projection 8 and partially deformed, as shown in FIG. 7C, so that the movement of the clamp body 1 in the electric wire wiring direction is prevented, and the so-called band clamp does not move laterally. This can be prevented.

Further, as shown in FIG. 7 (b), by providing the clamp body 1 with an anchor projection 11 that can be engaged with the mounting hole 10 of the panel 9, a panel or the like can be attached via the anchor projection 11. There is a band clamp that can be attached (see Japanese Utility Model Laid-Open No. 54-69385), and when wiring is performed with such a band clamp, the electrical wire 7 and the connector (not shown) are held in a fixed positional relationship when mounting. It is important to prevent lateral slippage for reasons such as work reduction.

8 (a) and 8 (b) show another example of a conventional band clamp (see Japanese Utility Model Laid-Open No. 4-48484).

In this band clamp, the band portion 2 is provided separately from the clamp body 1, and the clamp body 1 has two insertion holes 3 through which the band portion 2 is inserted, which are substantially parallel to the support portion 6. Is formed in. Flexible check claws 4 are provided in the insertion holes 3 to prevent the band portions 2 from moving in opposite directions.

The band portion 2 is attached to the clamp body 1 in a state in which the one end side is inserted into the one insertion hole 3 and thus is prevented from moving in the opposite insertion direction. After the band portion 2 thus attached is wound around the electric wire 7, the electric wire 7 is bound and fixed to the support portion 6 by inserting the band portion 2 into the other insertion hole 3 and pulling the electric wire 7.

According to such a band clamp, the length of the band portion 2 can be freely set as appropriate. Even when the clamp body 1 and the band portion 2 are separately provided in this manner, the lateral displacement of the band clamp is prevented by providing the projection 8 on the support portion as shown in FIG. 8B. can do.

[0011]

[Problems to be solved by the device]

 However, the band clamp provided with such a protrusion 8 can prevent lateral displacement satisfactorily when the number of bundled wires 7 is small or when the wires 7 are flat. When binding the wire harness 12 in which the electric wires 7 are bundled into a substantially cylindrical shape, as shown in FIG. 9A, the protrusions 8 have a large number of portions 8a and 8b that are not in contact with the wire harness 12. However, only a part of the wire harness 12 is pressed, the deformation becomes insufficient, and there is a possibility that the lateral displacement cannot be prevented. In particular, when the diameter of the wire harness 12 is large, the band clamp is likely to be laterally displaced.

When the band clamp is attached to the panel or the like by the anchor protrusion 11, when the band clamp laterally shifts, the wire harness 12 moves and the positional relationship with the connector or the like is not maintained constant, and the wire harness 12 The installation workability of will deteriorate.

Here, as shown in FIG. 9B, the shape of the protrusion 8 is formed so as to match the outer peripheral shape of the wire harness 12, and the lateral displacement is caused by increasing the contact portion between the protrusion 12 and the wire harness 12. It is also possible to prevent it. However, if the shape of the protrusion 8 is set to a predetermined curved surface in this way, the diameter of the wire harness 12 that can be bound is limited by the shape of the protrusion 8.

The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to prevent lateral deviation satisfactorily regardless of the outer peripheral shape of the wire harness, and in particular to have a large diameter. It is to provide a band clamp suitable for binding a cylindrical wire harness.

[0015]

[Means for Solving the Problems]

 In order to solve the above problems, a band clamp according to the present invention includes a clamp body having a support portion for supporting a long member, and a long member supported by the support portion on a support portion of the clamp body. A flexible band portion that binds and fixes the elongated member in a direction intersecting with the elongated member, and at least an intermediate portion of the elongated protrusion in the extending direction is long. It is characterized in that the flexible member is formed so that the protruding height can be arbitrarily changed by the abutting force from the scale member.

[0016]

[Action]

 When the elongate member supported by the support part of the clamp body is bound and fixed to the support part by the band part, the projecting height is increased at least at the middle part in the extending direction of the ridge due to the abutting force from the elongate member. Instead, the ridge has a shape that matches the outer peripheral shape of the long member. As a result, the contact portion between the elongated member and the ridge is increased, and the lateral displacement of the band clamp is effectively prevented.

FIG. 4 is a perspective view, FIG. 4 is an arrow view from the direction B in FIG. 3, and FIG. 5 is a cross-sectional view taken along the line CC in FIG. The description is omitted.

This band clamp is similar to the one shown in FIG. 8 in that the clamp body 1 having the support portion 6 and the band portion 2 having the plurality of recesses 5 are separately provided. The clamp body 1 is formed with two insertion holes 3 each having a check claw 4 therein. When the band portion 2 is inserted into each of the insertion holes 3, the check claw 4 and the recess 5 are engaged with each other while preventing the band portion 2 from moving in the opposite insertion direction.

A mountain-shaped protrusion 13 is provided on the support portion 6 along a direction that intersects the wire harness 12 substantially vertically. The ridge 13 is flexible, and a hollow portion 14 having a substantially triangular cross section is formed in the ridge 13 so as to penetrate in the same direction as the extending direction of the ridge 13. When the abutting force from the wire harness 12 acts on the middle portion of the protrusion 13 in the extending direction, the cavity portion 14 is narrowed as shown in FIG. 3 and FIG. The protruding height of the ridge 13 in the ridge 13 is changed arbitrarily. As a result, the contact area between the protrusion 13 and the wire harness 12 increases.

At the time of use, the band portion 2 is wound around the wire harness 12 and then pulled in the X direction in FIG.

At this time, the wire harness 12 is pressed in the Y direction in FIG. 1 by the band portion 2, and the abutting force from the wire harness 12 acts on the intermediate portion of the protrusion 13 in the extending direction. When the abutting force is applied, the cavity portion 14 is narrowed, and the ridge 13 is deformed into a shape that matches the outer peripheral shape of the wire harness 12. As a result, the contact portion between the wire harness 12 and the ridge 13 increases, and in accordance with the increase in the contact portion, the movement of the wire harness 12 in the wiring direction is more strongly prevented, and the lateral displacement of the band clamp is effective. To be prevented.

In this way, the ridges 13 are arbitrarily deformed into a shape that matches the outer peripheral shape of the wire harness 12, so that the ridge 13 can be prevented from swaying regardless of the outer peripheral shape and the diameter of the wire harness 12. can do. Further, even in the case of binding a single wire or a plurality of wires, the lateral displacement can be prevented as in the case of the wire harness 12.

Further, as shown in FIG. 5, when the clamp body 1 is provided with the anchor protrusions 11 engageable with the mounting holes 10 of the panel 9 and wired, the wires 7 in the wire harness 12 and The positional relationship with an external connector or the like can be kept constant, and the workability of attaching the wire harness can be facilitated.

A plurality of protrusions 13 may be provided, and the shape of the protrusions 13 is not limited to this.

For example, as shown in FIG. 6, a portion of the ridge 13 which is in contact with the wire harness 12 may be a flat surface 13 a, and the cavity portion 14 is formed by penetrating in the same direction as the wire harness 12. May be. When the portion that contacts the wire harness 12 is the flat surface 13a, the projection 8 similar to the conventional one can be further provided on the flat surface 13a.

The present invention is not limited to the above embodiment.

[0028]

[Effect of device]

 As described above, according to the band clamp of the present invention, the protrusion is deformed into a shape that matches the outer peripheral shape of the long member, so that the lateral displacement of the band clamp is prevented regardless of the outer peripheral shape of the long member. In particular, when the long member has a cylindrical shape with a large diameter, lateral displacement can be effectively prevented.

When the band clamp is attached to a panel or the like to dispose the long member, the disposition position of the long member can be reliably maintained.
