Description

[Detailed description of the invention] This invention relates to fasteners such as wire harnesses installed in vehicles, etc., and more specifically, when a wire harness etc. is installed in a cross-shape with attached parts, such as component mounting brackets, etc. It is an object of the present invention to provide a fastener that can securely fix a wire harness or the like in a stable state by using a supporting part of a part or a fastening part thereof.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is a bracket for, for example, an alarm device to which a body 2 is attached, and the bracket 1 is connected to the body 2 through a bolt 3 and a washer 4. has been concluded. The wire harness W, which is disposed intersectingly with the bracket 1 attached via the bolts 3 and washers 4, is disposed via the fasteners 5.

Reference numeral 5 denotes the entire fastener of the wire harness W, which is made of synthetic resin, etc., and 6 is a fixing part formed in a substantially horizontal U-shape, with a predetermined width H.
The end of the upper piece 7 has a folded edge 8 upwardly in the drawing. Further, on both left and right sides of the lower piece 9 of the fixing 6, grounding pieces 10 are formed in a stepped manner from the upper surface 9a of the lower piece 9, corresponding to a predetermined projecting width, that is, the width of the bracket 1. A locking portion 11 is provided vertically at the end. This locking part 11 is made up of a clamping piece 12 and a locking pawl 13. The clamping piece 12 is provided in a corresponding inwardly inclined shape as shown in the figure, and the locking pawl 13 is provided at the lower end of the clamping piece 12. The left and right locking claws 13 are arranged to be inclined outwardly downwardly and upwardly inclined inwardly as shown in FIG. Also,
A reinforcing rib 14 is provided on the outer surface of the clamping piece 12. Further, a support piece 15 having a substantially hook-shaped cross section is provided on the end of the lower piece 9 of the fixing part 6, facing upward and reducing the opening side of the fixing part 6. An opening 16 is formed between the upper piece 7 and the upper piece 7. Further, a substantially hook-shaped locking piece 17 is provided horizontally at approximately the center of the upper end of the support piece 15 and can be engaged with the head 3a with a width that can cover almost the entire head 3a of the bolt 3. Formed locking piece 17
A slip-preventing recess 18 is formed on the lower surface side. Furthermore, a locking portion 1 is provided approximately in the center of the lower surface of the lower piece 9.
Reinforcement block 19 to prevent 1 from opening too much
The lower surface of the block 19 is formed at approximately the same level as the lower surface of the grounding piece 10. The fixing part 6 formed in this way is provided so as to be elastically deformable so that the opening 16 can be opened and expanded, and the grounding piece 10 and the lower piece 9 are provided so as to be elastically deformable so that the left and right engagement can be performed. The stop portion 11 is formed to be expandable.

Next, the operation and effect of the fastener 5 configured as described above will be explained.

Now, the fastener 5 of this example is for attaching a wire harness W disposed intersectingly with the component mounting bracket 1 etc. attached to the body 2 via the bolt 3, and has a substantially horizontal U-shaped fixing part. A substantially hook-shaped support piece 15 is provided on the end of the lower piece 9 of the fixing part 6 so that the opening side of the fixing part 6 is reduced, and the upper end of this support piece 15 extends horizontally and is bent downward. A locking piece 17 that engages with the head 3a of the bolt 3 is provided.
A retaining recess 18 is formed on the lower surface side of the bracket 7, and a grounding piece 10 is provided on both sides of the lower piece 9 in a step-like manner that projects sideways corresponding to the width of the bracket 1. The part is provided with a locking part 11 consisting of a clamping piece 12 that hangs downwardly inward and a locking pawl that is installed oppositely in an expanding manner at the lower end of the clamping piece 12. It is. Therefore, first, the fastener 5 is assembled by engaging the locking piece 17 with the head 3a of the bolt 3 that fastens the bracket 1 in advance, and pressing the locking portion 11 against the width edge of the bracket 1. The left and right clamping pieces 12 have surfaces 13a of locking claws 13 disposed opposite to each other in an expanded shape at their lower ends, and are slidably guided by the edges of the bracket 1, and are elastically deformed in an expanded shape. Further, when the locking pawl 13 passes through the edge of the bracket 1 by pressing, the clamping piece 12 is elastically restored and the locking pawl 13 is locked to the back surface of the bracket 1. When the locking pawl 13 is in the locked state, the reinforcing block 19 formed on the lower surface of the lower piece 9 comes into contact with the upper surface of the bracket 1, so that the reinforcing block 19 can be used as shown in FIG. The amount of expansion and expansion of the locking portion 11 is regulated, and the restoring force of the locking portion 11 is assisted to increase the locking force, thereby making it possible to securely fix the locking portion 11 firmly. Next, when the wire harness W containing the wires is brought into contact with and pressed along the opening 16 of the fixed part 6, the fixed part 6 is elastically deformed, the upper piece 7 is pushed up, and the opening 16 is expanded. , as soon as the wire harness passes through, it elastically restores itself and the wire harness W
are fixed to the fixing part 6 in a clamping manner and arranged in a cross-like manner on the bracket 1. In addition, since the retaining recess 18 is provided to engage the bolt 2 fastening the bracket 1 in a crowned manner, it is possible to prevent the fastener 5 from shifting in the longitudinal direction of the bracket 1.

Now, the present invention is a fastener for attaching a wire harness which is arranged in a crosswise manner with a component mounting bracket etc. attached to the body via bolts, and the lower end of the fixing part is approximately horizontally U-shaped. A substantially hook-shaped support piece is provided above the opening side of the fixing portion in a contracted manner, and a locking piece that extends horizontally from the upper end of the support piece and is bent downward to engage with the head of the bolt. is provided to form a retaining recess on the lower surface side of the locking piece, and grounding pieces are provided on both sides of the lower piece that protrude sideways in a step-like manner corresponding to the width of the bracket;
In addition, the end of this grounding piece is provided with a locking part consisting of a clamping piece that hangs downwardly inward and a locking pawl that is installed oppositely in an expanding manner at the lower end of the clamping piece. By doing so, the brackets can be used to securely fasten the fasteners and the wire harnesses can be arranged in a crosswise manner, and the bracket mounting bolts can be used to prevent misalignment. This is an extremely practical idea as a fastener.
