Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded protector for a linear body, and more particularly to a protector for accommodating a wire bundle of a wire harness and mounting it on a vertical surface of a vehicle panel or the like to arrange and hold the wire harness. Regarding

[0002]

2. Description of the Related Art In recent years, resin-molded protectors have been widely used as means for adjusting the mounting posture of electric wire bundles, optical fiber bundles, air pipe bundles, etc., such as those for vehicles. FIG. 3 (a) shows a molding protector for a vehicle panel mounting type wire harness according to the prior art. A groove-shaped protector body 1 and a hole portion 3 having a rotation fulcrum (hinge portion) at one side wall end portion thereof and engaging with a protrusion 3a of the other side wall.
The lid 2 having b and the plate-shaped partition 4 protruding from the bottom surface of the protector body 1 are integrally molded of resin. In the protector having such a structure, when the wire bundle 8 is housed in the wiring directions 7 and 7'and the lid 2 is closed, the housing state is poor, and the wires 8'routed across the partition 4 are arranged. Has been caught between the lid body 2 and has been a cause of damage to the electric wire and distortion of the shape of the protector.
As a method for solving such a problem, for example, there is a method disclosed in Japanese Utility Model Publication No. 6-49057. In this method, as shown in FIG. 3 (b), the partition portion 4 has a pin-like structure, and a hole 5 for locking the pin tip is provided on the lid side to eliminate an electric wire that crosses over the partition portion. Is being prevented.

Further, when the protector containing the bundle of electric wires is mounted on the vehicle panel, it is necessary to prevent the protector and the bundle of electric wires from being displaced from each other in order to maintain the relative positional relationship between them. For this reason, the electric wire bundle normally housed in the protector must be manually bound and fixed at several places, for example, with a binding tape to prevent it from slipping. As a method for solving such a problem, for example, Japanese Utility Model Laid-Open No. 62-1
There is a method shown in Japanese Patent No. 19109, Japanese Utility Model Laid-Open No. 6-88128, etc., and the electric wire pressing mechanism provided so as to project from the protector body side or the lid side fixes the electric wire to prevent the protector and the electric wire from being displaced. There is.

[0004]

In the conventional protector as described above, in the structure in which the partition portion is in the shape of a pin (Japanese Utility Model Publication No. 6-49057), the wire is effectively caught when the wire bundle is stored. Can be prevented. However, as shown in FIG. 4, the protector accommodating the bundle of electric wires 8 is locked with the clamp 1a in the mounting hole 10 provided in the vertical surface of the vehicle panel 9 or the like (the side wall portions are arranged vertically). When mounted and fixed, there is a problem that the wire bundle 8 is biased by its own weight as shown in FIG. 5A, an excessive load is applied to the partition pin 4, and the partition pin 4 and the lid 2 are damaged.

As a method for solving such a problem, it can be considered to improve the strength of the partition pin 4. As a concrete method, it is conceivable to increase the number of pins or increase the pin diameter. For example, if the number of pins is increased, the number of holes on the lid side also increases and the strength of the lid decreases, and When the pin diameter is increased, the hole diameter on the lid side is also increased, the strength of the lid is similarly reduced, and the capacity of the protector is reduced, resulting in a new problem that the storage capacity of the wire bundle is reduced. FIG. 5B shows a mounting cross section of the protector when the number of partition pins is increased. The electric wire bundle 8 is biased by its own weight and pushes out the lid body 2 whose strength is lowered, and deforms the shape of the entire protector. Such deformation of the protector causes interference with peripheral parts, which causes a vibration noise when the vehicle is running, and reduces the durability of the protector.

In addition, when the partition portion is in the shape of a pin, there is a problem that friction with the bundle of electric wires is small and the deviation from the protector is likely to occur. Entrapment to prevent such misalignment,
Alternatively, in the pressing-in structure (Japanese Utility Model Laid-Open No. 62-119109, Japanese Utility Model Laid-Open No. 6-88128), it is necessary to project the wire holding portion from the protector body or the lid portion, so that the protector is larger than the wire bundle. Therefore, it is not practical in relation to peripheral parts when mounted on a vehicle panel.

An object of the present invention is to solve the above problems and
It is an object of the present invention to provide a molded protector for a linear body, which is not deformed or damaged even when mounted on a vertical surface of a vehicle panel. Especially,
The cross-sectional shape of the partition in the groove extension direction is wide at the base and narrow at the tip, and by having an inclined structure from the tip to the base, it is resistant to deformation due to bias of the wire bundle in the protector, and An object of the present invention is to provide a protector capable of suppressing deviation and preventing biting by the lid portion during storage.

[0008]

In order to achieve the above object, the invention according to claim 1 stores a linear body in a groove-shaped protector main body, and closes an opening of the protector main body with a lid. In the protector, which has a protrusion that protrudes from the bottom surface inside the protector body groove and that engages with a hole provided in the lid, the protector body has a cross-sectional shape in the groove extending direction from the part to the base direction. It is characterized in that a partition portion having an inclined structure is provided in the.

With this construction, when the electric wire bundle is housed in the protector body, the electric wires on the partition portion are pushed down when the lid is closed, and the inclined portion is slid out. Further, by forming the width of the base portion in the sectional shape of the partition portion wider than that of the tip portion, the strength of the partition portion against the load of the wire bundle when the protector is mounted and fixed on the vertical surface is improved. Furthermore, by making the shape of the partition part flat or three-dimensional, the contact with the wire bundle and the frictional resistance increase.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments. FIG. 1 is a diagram showing an embodiment of a protector according to the present invention. In the figure, reference numeral 1 denotes a protector body, which is provided with a lid body 2 having a pivot point (hinge portion) at one side wall end portion, and is engaged with a protrusion 3a provided at the other side wall end portion of the protector body 1. The lid lock portion 3 is formed by the hole portion 3b that fits. A plate-shaped partition portion 4 projects from the inner bottom surface of the protector body 1, and a projection 4a at the tip of the partition portion 4 engages with a hole 5 provided in the lid 2.

In such a structure, the electric wire bundles 8 to be inserted into the protector body 1 are sorted by the partitioning portions 4 and are housed in the wiring directions 7 and 7 '. Then, the lid body 2 is rotated so that the hole portion 3b becomes the protrusion 3a of the protector body 1.
The protrusion 4a of the partition 4 is engaged with the hole 5 of the lid 2 at this time. Here, when the partition section 4 of the present invention is described in detail, it is not limited to the plate shape shown in FIG. That is, as shown in FIG. 2A, the cross-sectional shape of the groove extending direction (the electric wire routing directions 7, 7 ') is wider at the base portion on the protector body 1 side than at the protruding portion 4a at the tip, and the protruding portion 4a is formed. It suffices to have the inclined portion 6 from the to the base portion. Due to such a shape, the electric wire 8'disposed on the partition portion 4 during the electric wire bundle storage operation is
It is pushed down by the closing work of and is moved along the inclined portion 6 in the direction of the sliding arrow. As described above, according to the present invention, since the partition portion 4 has the inclined portion 6,
The conventional combination of the partition plate and the pin as shown in (b) has an effect that cannot be achieved. That is, FIG.
In the partition portion 4 having the shape as shown in FIG.
The electric wire 8'crossing the partition 4 is crushed and damaged by the closing work of 1. or the lid 2 is distorted and the protector interferes with the peripheral parts to generate a vibration noise during traveling, which is different from the conventional technique. No improvement can be obtained.

Therefore, the shape of the partition portion 4 of the present invention is
As shown in FIG. 2 (c-1), a triangular aggregate may be used, or as shown in FIG. 2 (c-2), a substantially conical shape may be used.
Further, the cross-sectional shape in the groove extending direction does not have to be a structure in which the inclined portion 6 is formed on the same side as shown in FIG. 2A, and the inclined portion is formed as shown in FIG. 2C-3. Only one side is required. As described above, it is sufficient that the inclined portion 6 has a function of escaping (sliding and moving) the electric wire at least when the lid body 2 is closed.

Needless to say, in order to fulfill this function, the angle formed by the inclined portion 6 has an appropriate inclination angle so that the electric wire 8'can escape when the lid 2 is closed. In addition, compared with the structure of FIG. 2 (a), the structures of FIGS. 2 (c-1), (c-2), and (c-3) can improve load resistance against the electric wire bundle and have a groove cross section. It is also possible to more effectively suppress the deviation of the wire bundle by forming the shape portion in the direction with a claw shape.

Further, the partition portion 4 of the present invention is not limited to the structure in which the base portions thereof are provided so as to be separated from each other as shown in FIG. 1, and the plurality of inclined portions 6 and the protrusion portions 4a share the same base portion.
Or a structure in which a plurality of bases are in close contact with each other and are continuously provided. Although the lid 2 and the protector main body 1 are integrated with each other in the present embodiment, the present invention is not limited to this, and it goes without saying that the lid 2 and the protector main body 1 may be separate parts. .
In this case, a structure in which a lock mechanism is provided at both side wall portions of the protector main body 1 and the corresponding portions of the lid body 2 is generally used.

According to the present invention as described above, the operator does not need to pay special attention to the biting of the electric wire, and since the plate-shaped partition portion 4 and the electric wire bundle 8 are in surface contact with each other, friction is increased,
Since the deviation between the protector and the electric wire bundle is also suppressed, it is possible to reduce the work of binding the electric wires for preventing the deviation. Furthermore, since the partition portion 4 can secure sufficient strength against the bundle of electric wires when the protector is mounted on the vertical surface, the number of partition portions 4 and the number of the hole portions 5 of the lid 2 can be reduced,
It is possible to prevent the strength of the lid 2 from decreasing.

[0016]

As described above, according to the present invention,
Since the partition part has a cross-sectional shape having an inclined structure, the strength of the partition part can be improved. Therefore, since a small number of partitions can support the load of the electric wire bundle, the number of partitions installed can be reduced. Moreover, since the number of holes in the lid corresponding to the partition can be reduced, the strength of the lid is not lowered.

Further, by providing the partition with the inclined portion, the electric wire to be housed is pushed out along the inclination of the partition when the cover of the protector is closed, so that the electric wire can be prevented from being caught. It is possible to provide a highly reliable molded protector for a wire harness that suppresses damage to electric wires and deformation of a lid. Therefore, it is possible to prevent the generation of vibration noise during traveling due to the interference with the peripheral components due to the deformation of the protector.

Further, by forming the partition part into a plate-like planar structure or a three-dimensional structure such as a rib shape, the friction resistance or the contact resistance between the housed wire and the partition part is increased, and the protector and the wire bundle are connected. Since the deviation of the wire can be suppressed, the wire binding work can be omitted or reduced.
