[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 5 show an embodiment of a harness protector according to the present invention.

The harness protector 1 is vertically (up and down) attached to a horizontally gutter-shaped protector body 2 made of synthetic resin.
A plurality of linear body locking portions 4 and 5 are arranged so as to insert and lock the linear body 3 from different directions such as a direction and a lateral (left-right) direction.

That is, as shown in FIG.
A first linear body locking portion 4 having a vertical linear body insertion portion 6 (FIG. 2) is provided at one end of the protector body 2, and a horizontal linear body insertion portion is inserted into a middle portion of the protector body 2 in the longitudinal direction. Two second linear body locking portions 5 having the portions 7 (FIG. 3) are provided in parallel.

As shown in FIG. 2, the first linear body locking portion 4 includes a pair of front and rear sandwiching walls 9, 9 raised from an upper wall 8 of the protector body 2, and a pair of sandwiching walls 9, 9. 9, a flexible holding piece 1 which is raised on the same plane as the side wall 10 of the protector body 2 and is positioned so as to be orthogonal to the holding wall 9.
1 and 1.

The pair of holding walls 9, 9 extend in the transverse direction of the protector, and the holding pieces 11 extend in the longitudinal direction of the protector. Each holding wall 9 and the holding piece 11 are protruded at the same height,
Linear body insertion portion (gap) between each holding wall 9 and holding piece 11
6 are constituted. Upper end of each holding wall 9 and holding piece 11
Locking projections 12 and 13 are formed at the upper end of the head, respectively, and an upward narrow inlet 6a is formed between the locking projections 12 and 13. Each locking projection 12, 13 has tapered guide surfaces 12a, 13a and locking surfaces 12b, 13b. An arc-shaped receiving surface 14 is formed at the lower end of each of the holding walls 9 and the lower end of the holding piece 11 to prevent the linear body 3 (FIG. 4) from being damaged.

At the upper part of the pair of holding walls 9, 9, a side opening 15 of a harness insertion portion (space) 15 of the protector body 2 is provided.
On the side a, the protector fixing portion 17 is integrally formed with the vehicle body 16 (FIG. 4). The protector fixing portion 17 includes a vertical substrate portion 18 that extends perpendicularly to the pair of holding walls 9, 9, and the locking clip 1 protruding from the substrate portion 18.
9. The board part 18 is located parallel to the holding piece 11.

At one end and the other end of the protector main body 2, fixing plates 21 for fixing the wire harness 20 (FIG. 4) with a tape are formed so as to protrude, respectively. On the other end side of the protector body 2, a bracket 22 for fixing the harness protector 1 to the vehicle body 16 (FIG. 4) by fixing means such as bolts is provided.

As shown in FIG. 3, the second linear body locking portion 5 provided at the intermediate portion of the protector main body 2 is raised from the side opening 15a side of the upper wall 8 of the protector main body 2. It comprises a base wall 23 and a flexible holding plate 24 formed horizontally from the base wall 23 and parallel to the upper wall 8.

The base wall 23 is formed narrower than the length of the holding plate 24 in order to impart elasticity to the holding plate 24. For example, the pair of base walls 23 support the holding plate 24. . A horizontal linear body insertion portion (space) 7 is formed between the holding plate 24 and the upper wall 8. Engagement projections 25 and 26 are formed opposite to the distal end of the holding plate 24 and the upper wall 8. Each locking projection 25, 26 has a tapered guide surface 25.
a, 26a and locking surfaces 25b, 26b. The entrance 7a of the linear body insertion section 7 is located between the locking projections 25 and 26.

A curved surface 27 is formed from the side wall of the protector body 2 to the upper wall (wall portion) 8, and the curved surface 27 continues to the entrance 7 a of the linear body insertion portion 7. The curved surface 27 functions as a guide surface for smoothly guiding the linear body 3 (FIG. 5) to the linear body insertion portion 7.

While the first linear body locking portion 4 inserts the linear body 3 from above as shown by the arrow A, the second linear body locking portion 5 has the same linear shape. The body 3 is inserted from the side as shown by an arrow C, and the linear body 3 comes out in two directions opposite to the insertion direction as shown by arrows B and D. The linear body 3 is sandwiched by the linear body locking portions 4 and 5 from four directions, that is, left and right and up and down. With this configuration, even if the linear body 3 comes out of one of the linear body locking portions (for example, 4) due to an external force acting on the harness protector 1 in one direction, the other linear body locking portion (5). Securely holds the linear body 3 and prevents the linear body 3 from completely detaching from the harness protector 1, that is, falling off.

FIGS. 4 and 5 show a state in which the harness protector 1 is fixed to the vertical wall 28 of the vehicle body 16 with the locking clip 19. The locking clip 19 is engaged with the hole 29 of the vertical wall 28. A wire harness 20 is inserted and fixed inside the protector main body 2, and each of the linear body locking portions 4, 5 is fixed.
And the same linear member 3 is continuously inserted and locked. The linear body 3 is held between the holding piece 11 and the pair of holding walls 9 in the first linear body locking section 4, and the second linear body locking section 5 is held.
Is held between the holding plate 24 and the upper wall 8 of the protector body 2.

In FIGS. 4 and 5, reference numeral 30 denotes a wheel house following the vertical wall 28. When the vehicle travels, the harness protector 1 receives, for example, vibration in the vertical direction. However, since the first linear body locking portion 4 in FIG. 4 has the upward linear body insertion portion 6, the linear body 3 There is very little risk of slipping out of the first linear body locking portion 4. In addition, since the second linear body locking portion 5 in FIG. 5 has the horizontal linear body insertion portion 7 orthogonal to the vertical vibration direction, it is extremely advantageous for vertical vibration. The linear body 3 does not fall out of the second linear body locking portion 5 due to the external force in the vertical direction.

Since the first linear body locking portion 4 is fixed to the vehicle body 16 by the locking clip 19 in the vicinity thereof, the first linear body locking portion 4 is hardly affected by an external force such as vibration, and the external force is small. Accordingly, the linear body 3 is unlikely to come out of the first linear body locking portion 4 even by the vertical vibration.
In addition to the vertical vibration, in the vehicle layout of FIG. 4, a large external force acts in the lateral direction (the direction of arrow E). In this case, the direction of the external force and the direction in which the linear body comes off, that is, the direction of the linear body insertion portion, Are orthogonal to each other, the linear body 3 is firmly supported by the holding piece 11 or the holding wall 9, and there is no fear that the linear body 3 comes out of the first linear body locking portion 4.

In the first linear body locking portion 4, the linear body 3
The insertion work of the first linear body locking portion 4 is slightly troublesome.
However, since the linear body insertion portion 6 is fixed to the vehicle body 16 by the locking clip 19 and is hardly affected by the vertical vibration, even if the linear body insertion portion 6 is oriented in the same direction as the vibration, the linear body 3 may not come out. Danger is minimized.

Since the second linear body locking portion 5 of FIG. 5 is located in the middle part of the harness protector 1, an external force such as vibration acts more than the first linear body locking portion 4. However, even if a large vertical vibration acts, the linear body 3 is firmly connected to the holding plate 24 and the upper wall 8 because the holding plate 24 and the upper wall 8 of the protector body 2 extend in a direction orthogonal to the vibration. Held between.

When an external force such as a lateral vibration is applied in addition to the vertical vibration, the direction of the external force coincides with the direction of the linear body insertion portion 7, so that the linear body 3 easily comes off. Even when the linear member 3 comes off, the linear member 3 is securely locked by the first linear member locking portion 4, so that the linear member 3 does not fall off the harness protector 1.

In the second linear body locking portion 5, since the entrance 7a of the linear body insertion portion 7 continues to the curved surface 27 on the upper part of the protector main body 2, the work of inserting the linear body 3 is easy. Thus, the workability of attaching the linear body 3 to the harness protector 1 is improved.

[0028]

As described above, according to the first aspect of the present invention, the insertion direction of the linear body into each linear body locking portion, that is, the exit direction of the linear body is different so as to intersect. When an external force such as vibration is applied, even if the linear body comes off from the linear body locking portion having the linear body insertion part that matches the direction of the external force, the linear body insertion part intersects with the direction of the external force Since the linear body locking portion having the shape firmly holds the linear body, the linear body does not fall out of the harness protector. This prevents the linear body from being damaged or twisted. The structure of the linear body locking portion itself may be the same as the conventional structure, and only the installation direction needs to be changed. Therefore, the structure of the harness protector and the molding die do not become complicated, and there is a fear of cost increase. Absent.

Further, according to the second aspect of the present invention, even if the linear body comes out of the first linear body locking portion due to an upward external force acting, the second linear body locking portion can be moved. Since the linear body insertion portion is positioned orthogonal to the direction of the external force, the linear body is securely held by the second linear body locking portion, and the linear body is securely prevented from falling off. . When a lateral external force is applied, on the contrary, the linear body is securely held by the first linear body locking portion, and the linear body is prevented from falling off. According to the third aspect of the present invention, since the external force such as vibration is minimized in the protector fixing portion, the linear member comes out of the first linear member locking portion even when an upward external force is applied. It becomes difficult. Also,
According to the fourth aspect of the present invention, since only one holding plate is required, the structure is simplified and the cost of the harness protector is reduced. Further, since the linear body is guided by the curved surface and is smoothly and easily inserted into the linear body insertion portion, the mounting workability of the linear body in a narrow space such as a vehicle is improved.
