Therefore, the definitions of the terms should be made based on the contents throughout the specification.

1 is a perspective view illustrating a wire harness fixing device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the wire harness fixing device of FIG. 1, and FIG. 3 is an enlarged cross-sectional view of A of FIG. 2. 1 to 3, the wire harness fixing mechanism 10 is a mechanism for fixing a wire harness (not shown) to a panel (not shown) of a vehicle, and includes a base member 30 and a peck ( peg) 11, bracket 40, and wire harness holder 45.

The base member 30 includes a flat plate portion 31 and a pillar 32 protruding to one side from the plate portion 31. The pillar 32 has a fastening through-hole 34 is formed, the upper end of the column 32 is formed with a locking projection 36 due to the fastening through hole (34). The pegs 11 are fitted to and supported by the pillars 32. The bracket 40 is fastened and fixed to the plate portion 31 by a plurality of bolts 51.

The peg 11 protrudes tapered in a wedge shape so that the diameter is narrow, and is detachably inserted and fixed in a mounting hole (not shown) of a panel (not shown) of the vehicle. The peg 11 has four legs 13. The pillar 32 of the base member 30 guides the four legs 13 as the peg 11 approaches to engage the base member 30. Four legs 13 pass by against the column 32. When the end of the leg 13 is blocked by the base member 30 and cannot proceed any further, the elastic hook 15 is inserted into and fastened to the fastening hole 34 of the pillar 32 so that the peg 11 is fixed to the base member ( 30) detachably coupled. When the pegs 11 are coupled to the base member 30, the four legs 13 are supported by the base member 30.

The pegs 11 are provided with a total of two elastic hooks 15, one between each of the pair of legs 13 of the four legs 13 and between the other pair of legs 13. The resilient hook 15 extends in a direction opposite to the direction toward the tip from the protruding end of the peg 11, ie from the hinge point 16 close to the tip 18. ).

The stopper of the lever 18 is provided with a pusher 20 to press the lever 18 to the inside of the peg 11. The pusher 20 has a pusher protrusion 21 protruding outward from the lever 18 and a pusher flange 22 extended so that the surface area is larger than the pusher protrusion 21. The pusher flange 22 has a shape that is bent and extended in a direction orthogonal to the direction of protrusion of the pusher protrusion 21 at the end of the pusher protrusion 21. Since the expanded pusher flange 22 enlarges the area of the portion under pressure, the operator can easily press the pusher 20 without pressure when the user pushes the pusher 20 with a fingertip and apply a larger pressing force to apply a large range of levers 18. ) Rotation is possible.

The lever 18 has a fastening protrusion 25 protruding from its distal end. The fastening protrusion 25 has a first bent portion 26 protruding outward from the lever 18 to be inserted into the fastening hole 34, and at the end of the first bent portion 26 of the pillar 32. A second bent portion 27 protrudes in the same direction as the protruding direction. One of the pair of side surfaces 18S and 27S of the lever 18 and the second bent portion 27 facing each other, and the first bent portion 26 positioned between the pair of side surfaces 18S and 27S. The separation prevention grooves 29 are defined by the side surfaces 26S. The inclined surface 28 is provided on the outer side of the first bent portion 26.

Meanwhile, the wire harness holder 45 is, for example, a member for holding and supporting a wire harness (not shown) by using a band or the like, and the other side opposite to one side of the base member 30 to which the peg 11 is coupled. Is coupled to. In detail, the base member 30 is provided with a male screw pillar 38 protruding to the other side and having a male screw formed on an outer circumferential surface thereof. The male threaded pillar 38 passes through the wire harness holder 45 and engages with a nut 53. The wire harness holder 45 is fixedly coupled to the other side of the base member 30 by the male screw pillar 38 and the nut 53.

Hereinafter, a process in which the base member 30 and the peck 11 are coupled to each other and a process in which the base member 30 and the peg 11 are separated from each other will be described. In order to couple the pegs 11 to the base member 30, the legs 13 of the pegs 11 are aligned with respect to the pillars 32 of the base member 30, and then the pegs may be covered as if the caps were covered. When the 11 is inserted into the pillar 32, the legs 13 of the peck 11 are guided and aligned with the pillar 32. As the peg 11 approaches the base member 30, the inclined surface 28 of the fastening protrusion 25 is pushed by the locking projection 36 so that the lever 18 rotates inward about the hinge point 16. . When the lever 18 is rotated inward and positioned inside the pillar 32, the lever 18 is elastically biased in the direction in which the pillar 32 is pressed outward by the elastic restoring force.

When the peg 11 comes closer to the base member 30, the end of the leg 13 is blocked by the base member 30, and the fastening protrusion 25 is inserted into the fastening hole 34 at the same time. Specifically, in the illustrated embodiment, the interval G1 of the fastening hole 34 is 6.2 mm, and the height H1 of the fastening protrusion 25 is set to 5.45 mm, so the fastening protrusion 25 is fastened to the fastening hole 34. When the equivalent level is reached, the lever 18 is rotated outwardly about the hinge point 16 by the elastic restoring force so that the fastening protrusion 25 is inserted into the fastening hole 34.

On the other hand, the width W1 of the first bent portion side surface 26S defining the separation preventing groove 29 is set to 2.5 mm which is equal to or slightly larger than the width of the pillar 32, and the width of the second bent portion 27 is increased. The height H2 is set to 2.0 mm, and the clearance G2 of the fastening protrusion 25 in the fastening hole 34 is set to 2.75 mm. When the peg 11 is pressed in the direction away from the base member 30 due to the vibration transmitted during the assembling stage of the vehicle or the driving of the vehicle, the fastening protrusion 25 is moved by the clearance G2 to be fastened. The locking jaw 36 of the upper portion of the through hole 34 is inserted into the separation prevention groove 29. At this time, the first bent portion side 26S is blocked by the locking jaw 36 and the second bent portion 27 is also blocked by the locking jaw 36 so that the fastening protrusion 25 is fastened with the fastening hole 34. Can't escape. In other words, the peg 11 and the base member 30 are not separated from each other by vibration during assembly or driving of the vehicle regardless of the intention of the operator.

In order to separate the peg 11 from the base member 30, first, the pair of pusher flanges 22 are pressed inward using the fingertips. If the locking jaw 36 is not inserted into the separation preventing groove 29, the height H1 of the fastening protrusion 25 is smaller than the gap G1 of the fastening hole 34, so that the lever 18 is the hinge point 16. It is possible to rotate inward about the center of the fastening protrusion 25 is escaped from the fastening hole (34). In this state, the peg 11 can be pulled away from the base member 30 to separate the peg 11 from the base member 30. When the pressure on the pusher flange 22 is released, the lever 18 is rotated outward about the hinge point 16 again by the elastic restoring force to restore the original state.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
