Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a wiring tool, and more particularly to a wiring tool in which a grommet portion and a wiring holding portion are integrally provided.

[Prior Art] When laying a wire harness of a vehicle in a panel, a resin or rubber grommet is often provided in a wiring opening of the panel. An example thereof will be described with reference to FIG. 5. A wiring opening P1 is provided in the panel P, and the wire harness W1 extending along the panel P is bent at a substantially right angle at the opening portion and inserted into the opening P1. ing.

Grommet 1'has a ring shape separated at one place,
Locking protrusions 11 'are formed at a plurality of positions on the periphery. The grommet 1'is reduced in diameter and inserted into the wiring opening P1 and locked and fixed by the locking projection 11 'so as to cover the opening edge. This prevents the wire harness W1 from coming into direct contact with the opening edge and being worn away due to vibration or the like when the vehicle is running.

Further, in order to suppress the positional fluctuation of the wire harness W1 in the opening portion, a clamp 2'for holding and fixing the wire harness W1 at a proper position is provided on the surface of the panel P close to the opening P1. For example, as shown
The locking leg portion 21 'is inserted into the mounting hole P2 provided on the surface of the panel P to be fixedly mounted.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional wiring structure, it is necessary to separately mount the grommet 1'and the clamp 2 ', which is troublesome. Also, the clamp 2 '
Despite the fixing by the wire harness W1, the position cannot be sufficiently fixed at the opening portion where the wire harness W1 is bent at a right angle, and as shown in FIG. 6, other wirings W2, W3, W4 are provided in the mounting opening.
The workability when passing it through was impaired.

The present invention solves such a problem, and an object of the present invention is to provide a wiring tool capable of significantly reducing the time and effort for fixing the wiring and improving the wiring workability.

[Means for Solving the Problems] The structure of the present invention will be described with reference to FIG. 1 and FIG. 2. The wiring tool is locked and fixed to the wiring opening P1 provided in the panel P so as to cover the opening edge thereof. The ring-shaped grommet portion 1 for relaxing the contact between the wiring passing through the opening P and the opening edge.
And a wiring holding portion 2 formed integrally with the wiring holding portion 2 for holding and fixing the wiring that extends along the panel and is inserted into the wiring opening P1. The wiring holding portion 2 includes a box body portion 21 having a U-shaped cross section that is connected to the grommet portion 1 and a lid body portion 22 that is rotatably connected to one of the opening edges 23 of the box body portion 21. The lid body portion 22 closes the opening of the box body portion 21 when the lid body portion 22 is rotated in the closing direction.
1 and a lid plate portion 222 inserted into the wiring opening P1.

[Operation] When the grommet portion 1 is locked and fixed to the opening edge of the wiring opening P1, the wiring holding portion 2 formed integrally therewith is also positioned at the same time. As a result, the work of separately fixing the wiring holder 2 is unnecessary.

When the lid portion 22 is closed, the wiring W1 along the panel P is held in the box portion 2 closed by the lid plate portion 221, and the wiring W1 is bent and extends into the opening P1 of the panel P to which the grommet portion 1 is attached. The bent portion has a box portion 22 and a lid plate portion 222.
Held by and. The wiring W1 is the opening P1 of the panel P.
Since it is held so as not to be displaced, other wiring can be passed through the opening P1 with good workability.

[Embodiment] In FIGS. 1 and 2, the wiring tool is an integrally molded product of resin, and the upper half portion is a grommet portion 1 and the lower half portion is a wiring holding portion 2.

The wiring holding portion 2 has an elongated box body portion 21 having a U-shaped cross-section, which is open to the side and has a small diameter at one end, and the open lower edge of the box body portion 21 is an integral thin deformable portion. The lid portion 22 is connected and formed by the hinge 23.

The lid body portion 22 has a lid plate portion 221 that closes the open opening of the box body portion 21 and a lid plate portion 222 that is bent and extended at a right angle from the lower end thereof and is inserted into the grommet portion 1. .

The upper wall 211 is cut out at a substantially central portion of the box body portion 21, and the side wall 212 has a semicircular concave shape at this portion and constitutes a part of the grommet portion 1. This concave portion 21
The guide wall 2 which is curved in a backward arc along the line 3
4 is projected.

Arc-shaped pieces 11 and 12 are symmetrically projectingly provided on the upper wall 211 of the box portion on both sides of the concave portion 213 to form the grommet portion 1. The arc-shaped pieces 11 and 12 have their tips opposed to each other with a space therebetween, and their base ends are smoothly continuous with the concave portion 213 to form a substantially ring shape as a whole.

Then, locking projections 13 and 14 are formed in a partially cut-and-raised manner near the tips of the arc-shaped pieces 11 and 12 and immediately below the recessed parts 213, and the grommet portion 1 has the arc-shaped pieces 11 and 12. , 12 are reduced in diameter so that the opposite ends thereof are close to each other, and are inserted into the wiring opening P1 of the panel P (FIG. 2),
The locking projections 13 and 14 lock and fix the opening edge so as to cover it.

In addition, locking projections 27 and 25 having locking grooves are formed on the lid plates 221 and 222 of the lid body 22, respectively.
With the lid portion 22 closed, the engagement protrusion 27 engages with the engagement protrusion 26 provided on the edge of the upper wall 211 of the box portion 21,
On the other hand, the locking projections 25 engage with both ends of the guide wall 24.

As described above, with the grommet portion 1 of the wiring tool attached to the wiring opening P1 of the panel P, the wire harness extending along the panel P is positioned in the box portion 21 and bent at a right angle to guide the guide. After inserting the opening P1 along the wall 24, the lid 22 is rotated by the integral hinge 23 to be closed.

This state is shown in FIG. In the figure, W1 is a wire harness, which has a semicircular cross section along the guide wall 24. The wire harness W1 is housed in the box portion 21 whose portion along the panel P is closed by the lid plate portion 221, and the bent portion entering the wiring opening P1 is between the lid plate portion 222 and the guide wall 24. It is held and fixed so that no position change occurs.

Then, above the wire harness W1,
As shown in FIG. 4, the other wirings W2, W3, W4 can be easily and efficiently passed. In particular, in this embodiment, since the wire harness W1 has a semicircular cross section along the guide wall 24, the wire harness W1 is securely fixed and the upper half portion of the wiring opening P1 can be effectively used.

It is needless to say that, as shown in FIG. 3, the wire holding portion 2 can hold another wire harness W5 which is not inserted into the wiring opening P1 and passes through the vicinity thereof.

[Advantage of the Invention] As described above, according to the wiring tool of the present invention, it is possible to fix the grommet portion and the wiring holding portion at the same time, so that the time and effort for fixing the wiring can be significantly reduced. .

Further, since the wiring is securely held and fixed at the bent portion to the wiring opening, its position does not change in the opening,
Other wiring can be passed through the opening with good workability, and wiring workability can be greatly improved.
