[Detailed description of the invention]

[0001]

The present invention is, for example, attached to a through hole of a harness formed in a predetermined panel of an automobile, and protects the harness inserted into the through hole from the leading edge of the edge of the hole. It relates to the improvement of the protector used for the purpose.

2. Description of the Related Art As conventional protectors of this kind, Japanese Utility Model Laid-Open No. 57-161282 and Japanese Utility Model Laid-Open No. 60-10937 have been known.
Japanese Patent Application Publication No. 7-No. These conventional protectors have some structural differences, but all have a rubber plug attached to the insertion hole side of the harness drilled in the panel, and a harness is provided inside the plug. A plurality of holding spaces for holding the same, and an expandable cut portion connected to each of the holding spaces is formed on the outer side of the plug body in the same direction, and from the expandable cut portion into the holding space. The harness can be inserted.

Therefore, even if the harness is held in the holding space of the plug under the conventional protector and the plug is attached to the insertion hole side of the panel, the harness comes into contact with the leading edge of the insertion hole. Then, it can be prevented from being damaged or cut, but especially in the case of targeting a harness connected by a connector or the like, do not forcibly pull the harness into the holding space of the plug body. In both cases, it is only necessary to obtain the expansion of the cut part and insert the harness into the holding space, so that the connector etc. gets stuck at the rim of the holding space and the work of pulling in the harness becomes complicated Thus, it is not difficult to pull in the harness.

[0004]

However, in the conventional protector, a plurality of cut portions connected to the holding space are formed on the outer portion of the plug body, so that the workability of inserting the harness into the holding space is good. On the other hand, the portion surrounded by each of the cut portions is partially separated from the plug when viewed as the entire plug, and the original rigidity obtained from the entire plug is obtained. When the plug is attached to the insertion hole side of the panel because it has been lost, it is necessary to prevent a portion surrounded by each cut portion from being easily deformed. Otherwise, due to the deformation of the portion surrounded by each cut portion, the plug body easily falls off from the insertion hole side, or the cut portion is inadvertently expanded with the above deformation, In any case, it is impossible to guarantee a secure holding state of the harness.

[0005] For this reason, under the conventional protector, screw through holes are formed at the four corners or the vertical direction of the plug, and the plug is screwed and fixed to the insertion hole side of the panel using the screw through holes. This prevents deformation of the portion surrounded by each cut portion and expansion of the cut portion itself.However, fixing the stopper to the insertion hole side with screws is not only an increase in the number of parts, but also However, since a complicated screwdriver is required in particular, there is a dislike that the operation of attaching the plug to the insertion hole side becomes extremely difficult. Also, even when a cut portion is formed, under a conventional protector, a plurality of cut portions are formed in the same direction, so that when harnesses are simultaneously inserted into each holding space, adjacent harnesses are connected to each other. It is highly possible that they interfere with each other and hinder the insertion operation.

[0006]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional protector, and has a plug attached to the insertion hole side of a harness formed in a panel. A plurality of holding spaces for holding the harness inside the plug body, and an expandable cutting portion connected to each of the holding spaces outside the plug body to form the expandable cutting section. In the harness protector configured so that the harness can be inserted into the holding space from the portion, the plug body has locking means for locking on the insertion hole side, and the cut portions are fixed to the outer portion. While forming in different directions,
A configuration in which the reinforcing wall portion extends toward the outer portion between the holding spaces is adopted.

[0007]

Therefore, according to the present invention, when the plug is attached to the insertion hole side, unlike the conventional case, the plug is not firmly screwed and fixed to the insertion hole side. ,
Since the rigidity of the portion surrounded by the cut portion is reinforced and its deformation can be effectively prevented, there is no fear that the plug easily falls off from the insertion hole side or the cut portion is inadvertently expanded due to the deformation. . Therefore, in the present invention, it is only necessary to attach the plug to the insertion hole side through its own locking means, so that it is possible to greatly reduce the number of parts and simplify the attaching work. Also, because the plurality of cut portions are formed in different directions, even when harnesses are simultaneously inserted into the holding space, adjacent harnesses may interfere with each other and hinder the insertion work. It can be prevented as much as possible.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a protector according to an embodiment of the present invention; FIG. It comprises a hollow ring-shaped outer frame 1 and a disc-shaped plug 2 removably fitted inside the hollow ring-shaped outer frame 1.

The outer frame 1 is integrally formed of a hard synthetic resin material and, as shown in FIG. 2, has a cylindrical shape having a dimension longer than the bent end of the insertion hole of the harness. The body 3 includes a flange 4 extending from one end of the cylindrical body 3, and a plurality of elastic members that are engaged with the bent end of the insertion hole with respect to the cylindrical body 3. The legs 5 are formed at regular intervals, and a plug 2 to be described later is formed on the inner peripheral surface side of the cylindrical body 3.
An annular step 6 for engaging the annular engaging claw 14 is integrally formed, and a plurality of notches 7 are provided at regular intervals with respect to the flange portion 4. The elastic wings 8 whose edges are inclined downward are formed.

Further, the latter plug 2 is integrally formed of a rubber material or a soft synthetic resin material, and has a concave inner portion fitted into the outer frame 1 as shown in FIG. 9 and a flange-shaped outer portion 10 extending around the periphery of the inner portion 9, and two holding spaces 12 separated from the inner portion 9 via a reinforcing wall portion 11 are defined. To form the respective holding spaces 12
Is closed by four thin film pieces 13 divided through a cross slit, and an annular locking claw 14 for locking to the annular step portion 6 is integrally formed on the outer surface side of the inner portion 9. I have.

The reinforcing wall portion 11 separating the two holding spaces 12 has a convex shape from the bottom surface of the inner portion 9 so as to extend in a belt shape from the center toward the outer portion 10 as shown in the figure. An enlarged form is provided at a portion where the holding space 12 is not integrally defined and is not defined.

In addition, two expandable cut portions 15 are formed in different directions on the outer portion 10 in the vicinity of each holding space 12 so as to be continuous with the corresponding cross slit of the holding space 12. The harness can be inserted into the corresponding holding space 12 from each of the cut portions 15.
In the present embodiment, a V-shaped cut 16 is made on the mouth side of each cutting portion 15 to facilitate insertion of the harness.

Accordingly, when the harness 17 is protected from the leading edge of the insertion hole 18 of the panel P by using the protector composed of the outer frame 1 and the plug 2, as shown in FIG. First, the outer frame 1 alone is engaged in advance with the bent end portion 18a of the insertion hole 18 of the panel P by obtaining a clamping action between the elastic wing 8 on the flange portion 4 side and the elastic leg 5 on the cylindrical body portion 3 side. Then, the harness 17 is pulled into the outer frame 1 as it is. When the harness 17 is pulled in, the lower side of the outer frame 1 extends below the bent end portion 18a of the insertion hole 18 as shown in the figure, so that a protective tape, a corrugated pipe, or the like is not required. Therefore, there is no fear that the harness 17 comes into contact with the leading edge of the bent end portion 18a.

Then, as shown in FIG. 5, each cut portion 15 formed on the outer portion 10 of the plug 2 is expanded near the outer frame 1 so that the outer frame 1 is opened. Is inserted into each holding space 12 of the plug 2, and finally, in this state, the annular locking claw 14 of the plug 2 is connected to the annular step 6 of the outer frame 1. To the plug 2
6 is tightly fitted into the inside of the outer frame body 1 as shown in FIG.
As shown in FIG. 7, the cut portions 15 are completely closed, whereby the harness 17 is elastically held in the respective holding spaces 12 by the action of the thin film pieces 13.
It is possible to effectively prevent the harness 17 from contacting the leading edge of the insertion hole 18 and being damaged or cut.

Therefore, even in the case of the present embodiment, when the harness 17 connected by the connector C or the like is targeted, the cutting portion of the plug 2 can be used without forcing the harness 17 into the holding space 12. With the spread of 15, the harness 17
Is simply inserted into the holding space 12, the harness 17 can be easily stored in the holding space 12. In particular, since the cut portions 15 are formed in different directions,
When the harnesses 17 are simultaneously inserted into the holding spaces 12, the adjacent harnesses 17 do not interfere with each other and hinder the insertion operation, and the reinforcement extending between the holding spaces 12. The presence of the wall 11 can also prevent interference between the harnesses 17.

Also, in this embodiment, two cutable portions 15 are formed on the outer portion 10 of the plug 2 so that the cutout 15 can be expanded. When viewed as the whole body 2, it is partially separated from the plug 2 and loses the original rigidity obtained from the entire plug 2,
As in the conventional case, when the panel P is attached to the insertion hole 18 side, specifically, when the panel P is fitted inside the outer frame 1 locked in the insertion hole 18, the portion is deformed. Must be effectively prevented.

However, in the present embodiment, as described above, the convex reinforcing wall 11 is extended between the two holding spaces 12 and cut by the presence of the reinforcing wall 11. Part 1
Since the rigidity of the portion surrounded by 5 can be reinforced and its deformation can be effectively prevented, the inner portion 9 of the plug 2 can be simply placed inside the outer frame 1 without using a conventional screwing structure. Just by fitting, there is no fear that the plug 2 easily falls off from the outer frame 1 or that the cutting portion 15 is inadvertently expanded due to deformation. Therefore, as compared with the conventional one, the number of parts is reduced and the work of attaching the protector itself including the plug 2 is greatly simplified.

Further, when the harness 17 is held, the outer frame 1 is engaged with the insertion hole 18 by the elastic clamping action of the elastic leg 5 on the cylindrical body 3 and the elastic wing 8 on the flange 4. Therefore, even if there is a dimensional error or the like between the two, the error and the like can be efficiently absorbed and the backlash of the protector itself can be prevented at the same time. The soundproofing effect can be sufficiently expected in combination with the close contact state of No. 13.

In the embodiment described above, two holding spaces 12 are defined so as to be close to the outer portion 10, and one reinforcing wall portion 11 extends between them. However, it goes without saying that the position and the number of the holding space 12 can be freely determined, and the elastic holding means of the harness 17 provided in the holding space 12 is not limited to the thin film piece 13 shown in FIG. As long as the expansion of the portion 15 is allowed and the harness 17 can be elastically held, it can be replaced with another structure according to the embodiment. Further, in the embodiment, the outer frame 1 and the plug 2 are formed in a similar round shape on the assumption that the insertion hole 18 of the harness 17 formed in the panel P is a round hole. The shapes of the outer frame 1 and the plug 2 can be appropriately changed according to the shape of the insertion hole 18.

Further, in the embodiment, the plug 2 is indirectly attached to the insertion hole 18 side of the panel P via the outer frame 1, but the present invention is not limited thereto. Alternatively, the plug 2 itself may be provided with locking means for the insertion hole 18 as the outer frame 1 has, so that the plug 2 is directly attached to the insertion hole 18 side. Needless to say, similar effects can be expected.

[0021]

As described above, according to the present invention, when the plug is attached to the insertion hole side by adopting the above configuration, it is not necessary to firmly screw the plug to the insertion hole side as in the related art. , The presence of the reinforcing wall reinforces the rigidity of the area surrounded by the cut section and effectively prevents its deformation, so that the plug easily falls off from the insertion hole side or the cut section itself is deformed. No more worrying about inadvertent expansion. Therefore, in the present invention, since it is only necessary to attach the plug to the insertion hole side via its own locking means, it is expected that a reduction in the number of parts and simplification of the attaching work can be greatly expected. Also, because the plurality of cut portions are formed in different directions, even when harnesses are simultaneously inserted into the holding space, adjacent harnesses may interfere with each other and hinder the insertion work. It can be prevented as much as possible.
