Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a fastener for installing a wire harness or the like to a steel plate body having a nut attachment hole formed therethrough.

(Prior Art) Conventionally, this type of fastener has a substantially flat substrate 102 with a convex-shaped protrusion 105 vertically disposed on the lower surface, and a cross-section of the substrate 102 from the edge thereof, as shown in FIG. A C-shaped holding piece 103 and a substantially flat mounting plate 104 are integrally formed, and the wire harness W is fitted between the holding piece 103 and the board 102, and a protrusion 105 vertically provided on the lower surface of the board 102 is attached to the steel plate. The locking hole penetrated through a part of the base plate 102 and the hole penetrated through a part of the mounting locking plate 104 are aligned with the nut mounting hole penetrated through the steel plate body 1. The wire harness W was fixed by tightening the washered bolt 3.

(Problem to be solved) In the above conventional technology, when tightening the bolt 3,
Although the substrate 102 is prevented from rotating by the protrusions 105, the mounting and locking plate 104 rotates, causing a problem in that the wire harness W is twisted.

(Means for Solving the Problems) The present invention has been made to solve the problems of the prior art described above, and is a wire harness that can prevent the wire harness etc. from twisting during installation and securely fix the wire harness. The purpose is to provide fasteners such as.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 4 is a fastener that is mounted with a mounting bolt 3 to a mounting hole 2 with a nut provided in the steel plate body 1. The fastener 4 is composed of a base plate 5, a holding piece 10, and a mounting and locking plate 11.

Reference numeral 5 denotes the above-mentioned board, which is formed into a substantially flat plate shape with a predetermined width, and on the left side of the board 5 in the upper diagram is a substantially hook-shaped locking piece 6 that locks the mounting locking plate 11. Furthermore, a locking protrusion 7 for preventing rotation of the mounting locking plate 11 is provided protruding from the upper surface on the holding piece 10 side.

Furthermore, a locking hole 8 having a diameter slightly larger than the nut mounting hole 2 provided in the steel plate body 1 is provided in a substantially central portion between the locking piece 6 and the locking protrusion 7 . Furthermore, 9
is a rotation-preventing protrusion that protrudes from the lower surface of the substrate 5 in the drawing and engages with the steel plate body 1.

Reference numeral 10 denotes a holding piece provided at the end of the substrate 5, which has a substantially U-shaped cross section.
The thin-walled portion and the thick-walled portion are continuously provided to provide elasticity.

Reference numeral 11 denotes a mounting and locking plate which is brought into contact with the substrate 5 in an overlapping manner, and is provided horizontally with a predetermined length from the end of the holding piece 10, and has a diagonal plate at the end. The locking plate 11 is provided with a hole 13 that aligns with the locking hole 8 penetrated through the board 5 and a locking projection 7 that fits into the top surface of the board 5. A stop hole 14 is provided through each of them.

Next, the operation and effects of this embodiment configured as described above will be explained.

First, the wire harness W is fitted between the holding piece 10 and the board 5, and then the attachment locking plate 11 is rotated so that its tip is engaged with the locking piece 6 so as to contact the board 5 in an overlapping manner. When they come into contact, the locking hole 8 and hole 13 of the board 5 are aligned, and the locking protrusion 7 and the engaging hole 14 are fitted, so that the board 5 and the mounting locking plate 11 are not misaligned. The wire harness W is held integrally with the wire harness W. Wire harness W like this
After gripping the fastener 4, the locking protrusion 9 is engaged with the mounting hole of the steel plate body 1, and then the locking hole 8 is aligned with the mounting hole 2 with a nut, and the locking hole 8 is aligned with the hole 13 and the locking hole 8 side. The fastener 4 is installed by inserting the mounting bolt 3 and tightening it with a tool such as an impact wrench.

At this time, when tightening the mounting bolt 3 with a tool such as an impact wrench, the mounting locking plate 11 tries to rotate in the tightening direction, but the locking protrusion 7 protruding from the upper surface of the board 5 and the mounting locking plate 11 The engagement hole 14 provided through the substrate 5 is fitted into the substrate 5.
Since the tip of the mounting and locking plate 11 is engaged with the locking piece 6 protruding from the upper surface, rotation is prevented, and the wire harness W can be securely fixed without twisting.

(Effect of the invention) The present invention is a fastener for fixing a wire harness, etc. to a steel plate body through which a mounting hole with a nut is formed, and a locking hole that can be aligned with the mounting hole is formed through the fastener. A substantially flat board is provided, and a substantially flat mounting and locking plate having a substantially U-shaped holding piece and a hole that can be aligned with the locking hole extends from the edge of the board. A convex locking protrusion is provided on a part thereof, a substantially hook-shaped locking piece is provided on the free end, and an engagement hole that can engage with the locking protrusion is provided on the mounting locking plate. Because they are integrally provided, even if rotational force is generated when tightening the mounting bolt, the locking protrusion and locking piece are engaged with the engagement hole and the tip of the mounting locking plate, respectively, making it easy to install. Since the locking plate can securely fix the wire harness etc. without rotating, it can be said that it is an extremely practical device as a fastener for the wire harness etc.
