Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a clamp fitting, particularly a clamp fitting used for clamping vehicle harnesses, cables, etc.

[Prior art] This type of clamp fitting is shown in Figs. 4 to 6.
The one shown in the figure is generally used.

The clamp fitting 1 shown in FIG.
A bolt hole 12 is formed at the other end. Further, the clamp fitting 1 shown in FIGS. 5 and 6 is
The metal plates are folded back and overlapped, and an eye-shaped clamped object holding part 11 is formed in the folded part, and a bolt hole 12 is formed in the overlapped part 10 to pass through this.

By the way, in order to prevent the clamp fitting from rotating when bolting the clamp fitting to the substrate, a device equipped with rotation prevention means is used. That is, in the clamp fitting 1 shown in FIG. 4, cutouts 13 are formed on the mounting base, and in the clamp fitting 1 shown in FIG. In the metal fitting 1, a protrusion 13' is formed on the edge of the lower plate of the overlapping portion 10, and the cut-out 13 and the protrusion 13' are inserted and locked into the rotation stopper hole 32 of the base plate 3.

[Problems to be Solved by the Present Invention] However, the rotation prevention hole 32 of the substrate 3 is generally difficult to work with due to the workability of inserting the cut-out 13 or the protrusion 13'.
The size is set to be large enough to accommodate these. Therefore, there is a risk that dust, water, etc. may enter directly from the rotation stopper hole 32 or through the hole created by forming the cut-out 13, and in particular, the intrusion of water may cause rust. So I don't like it.

Therefore, the purpose of the present invention is to provide a clamp fitting equipped with a rotation prevention means for locking a cut-out in a rotation prevention hole of a board, with a structure that prevents foreign substances such as dust and water from entering through the rotation prevention hole. do.

[Means for Solving the Problems] As shown in FIGS. 1 to 3, the clamping fitting of the present invention is made by folding and overlapping metal plates, forming a clamped object holding part 11 in the folded part, and The present invention is characterized in that a bolt hole 12 is formed in the overlapping part 10 where the plate 10a and the lower plate 10b are superimposed and in close contact with each other, and a cut-out 13 is formed in the lower plate 10b of the overlapping part.

[Operations and Effects] The clamp fitting of the present invention is set by locking its cut-out 13 into the rotation stopper hole 32 of the clamp mounting board 3, and is bolted and fixed to the board 3 through the bolt hole 12.

Therefore, the lower plate 10 generated by forming the cut-and-raised portion 13
Since the hole b and the rotation stopper hole 32 of the substrate 3 are covered by the upper plate 10a of the clamp fitting, foreign substances such as dust and water will not enter through the rotation stopper hole 32.

[Example] Embodiments of the present invention are shown in FIGS. 1 to 3.

The clamp fitting 1 is made of rectangular metal plates that are folded back and stacked on top of each other. The folded portion has an eyelet shape and serves as a clamped object holding portion 11 through which a clamped object such as a harness or a cable is inserted and held. Overlapping part 1
0 has an upper plate 10a and a lower plate 10b closely superposed, and a bolt hole 12 passing through the upper plate 10a and the lower plate 10b is formed at the tip. A cutout 13 is formed in the lower plate 10b at a position between the holding portion 11 and the bolt hole 12 and projects downward.

On the other hand, the clamp mounting board 3 is provided with a bolt hole 31 corresponding to the bolt hole 12 and a circular rotation stopper hole 32 corresponding to the cut-out 13 at the clamp fitting mounting position.

When installing the clamp fitting 1, insert and lock the cut-out 13 into the rotation stopper hole 32 of the board 3, align both bolt holes 12 and 31, insert the bolt 2, and tighten the bolt using a nut (not shown). Fix it.

Since the raised cutout 13 is locked in the rotation stopper hole 32, the clamp fitting 1 will not rotate during bolt tightening. The rotation stopper hole 32 is formed in the upper plate 10 in close contact with the lower plate 10b.
Since the hole 32 is covered by the hole 32, foreign substances such as dust and water will not enter through the hole 32.

Note that the bolt hole 12 in the clamp fitting 1
Regarding the positional relationship between the cut and raised portions 13, the bolt holes 12 may be placed on the side of the clamped body holding portion 11, and the cut portions 13 may be placed on the tip side.
