Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a band clamp for bundling linear objects such as electric wires and tightening them with a band to fix them at a desired position on a machine, a panel, etc.

[Conventional technology]

Many linear bodies such as electric wires, cables, and wire harnesses are used in power distribution boards of various machines and wiring in automobiles, etc., but if only these wires were wired individually, it would look very messy. In addition, a large amount of space is required, and the lines may become mixed up with each other, which may cause wiring problems later on. Therefore, it is necessary to appropriately bundle these linear bodies and fix them to a panel or the like to keep them in an orderly manner, and band clamps are used for this purpose. Regarding this band clamp, there is a technique disclosed in Japanese Utility Model Application No. 54-69385, which will be explained using FIG. 4.

A band-shaped band 4 protruding from a band clamp body 11 surrounds a bundle of linear bodies 9 and enters and passes through an insertion hole 13 provided in the body 11. A plurality of fitting recesses 14 are provided in the band so as to be perpendicular to the length direction of the band. And the insertion hole 13 of the main body 11
When the band is loosely inserted inside, the non-return claw 16 of the non-return means 15 fits into the fitting recess 14, and the bundle 9 of linear bodies is bundled. The bundle of linear bodies is tightened by strongly pulling the tip 12 of the band using a jig, and the bundle of linear bodies 9 is also tightened by fitting the clamp 17 into the mounting hole 19 provided in the panel 18. Fixed.

FIG. 5 shows a state in which a band clamp is attached to a bundle of linear bodies. An operator 22 works on the assembly jig 21 in the position shown in the figure, and uses the tightening tool 10 to tighten the tension band by pulling the tip of the band to fix the band clamp to the bundle of linear bodies 9. There is. Therefore, if the clamp body 11 is not within the range A' in FIG. 6, the operator will not be able to work, and in this case, the attachable range of the clamp 17 will be limited to the range A in FIG. 6. Ru. Even if the clamp 17 is desired to be within the range B due to the conditions of the attachment partner, the clamp 17 cannot be tightened, and the clamp 17 cannot be moved in position after tightening due to the large tightening force. In such a case, when attaching it to the other party, the linear body 9 must be twisted and attached, which has the disadvantage that it is likely to untwist and come off after attachment.

[Problem that the invention attempts to solve]

In order to eliminate the drawbacks of the prior art described above, the present invention provides a band clamp in which the position of the clamp can be freely determined when tightening the band clamp, regardless of the working position of the operator or the tightening position of the band. The purpose is to

[Means for solving problems]

In order to achieve the above object, the present invention includes a body part provided with a fitting clamp fixed to a support member, and a band clamp having a flexible band, in which a band passes through a through hole provided in the body part. A fixing means is provided at one end, and the fixing means has a tightening hole into which the other end of the band is loosely inserted, and a locking mechanism that prevents the loosely inserted band from returning.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. In Fig. 1a, the clamp main body 1 has a fitting fixing clamp 2 for fixing the main body itself to a panel, etc., and a through hole 3 through which a band is passed is bored in the base thereof, as shown in Fig. 1b. It is being

A band 4, which is separate from the clamp body 1, passes through the through hole 3 and is loosely inserted into the through hole 3 so as to be movable therein. this band 4
A lock portion 5 is provided at one end thereof, and the lock portion 5 has a tightening hole 6 for passing the band 4 therethrough and tightening it. The band 4 and the locking portion 5 are tightened and fixed by known means. For example, as shown in FIG.
4 and the lock portion 5 is provided with a non-return pawl 16, the purpose is achieved.

A flexible projection claw 8 protruding outward from the width of the band is provided near the other end 7 of the band 4 as shown in FIG. By making W' larger than the width W of the band and also larger than the width D of the through hole 3 shown in FIG. 1b, the band 4 can easily come off after being fitted into the main body 1. is prevented.

Next, a method for attaching this band clamp to a bundle of linear bodies will be explained with reference to FIG. band 4
surrounds the bundle 9 of linear bodies, and the other end 7 is inserted into the tightening hole 6 and, after passing through, is tightened and fixed by a tightening jig 10. At this time, as described above, the position of the lock portion 5 of the band 4 is limited to the range A in the figure due to the positions of the operator and the tightening jig. However, since the clamp body 1 can move freely on the band 4,
This allows for arbitrary positioning within the range C that does not overlap with the lock portion 5.

FIG. 3 shows the band clamp attached to the linear body. Thereafter, the bundle 9 of linear bodies is fixed at a desired position by fitting and fixing the clamp 2 into a mounting hole or the like of a panel (not shown).

[Effect of idea]

In the band clamp according to the present invention, the clamp body and the band are separated, so the clamp position can be determined without being restricted to the tightening position, and when fitting and fixing to a panel etc., the linear body can be fixed. It eliminates the need for screwing to install, and prevents troubles such as coming off after fitting and fixing.
