Description

[Detailed description of the invention] [Industrial application field] The invention relates to a protector used for protecting a wire harness or the like.

[Prior Art] Conventionally, a protector such as a wire harness is divided into a main body capable of accommodating the wire harness and a lid closing an open portion of the main body. Generally, a lock claw is formed on the lid, and a lock receiver is formed on the main body.

That is, after the wire harness is accommodated in the main body, the lid is put on the main body, whereby the lock claw is engaged with the lock receiver, and the main body and the lid are locked.

[Problem to be Solved by the Invention] In the conventional protector, there is a necessary and unavoidable gap between the lock claw and the lock receiver after they are engaged. This gap causes rattling at the joint between the main body and the lid, and generates abnormal noise when the protector is subjected to vibration.

The technical problem of the present invention is to provide a protector that can suppress rattling between a main body and a lid after engagement between a lock claw and a lock receiver and can prevent generation of abnormal noise due to vibration.

[Means for Solving the Problems] In order to solve the problems, a protector such as a wire harness in the present invention is configured as follows.

That is, a lock claw is provided on one of the main body capable of accommodating the wire harness and the like and the lid closing the opening thereof,
A protector such as a wire harness in which a lock receiver is formed and the main body and the lid are locked by engaging the lock claw and the lock receiver. A stabilizer projecting toward the other side is formed, and the stabilizer is compressed between the main body and the lid when the lid is put on the main body and the lock claw and the lock receiver are engaged with each other. It is set to have an elastic force in a direction to close a gap between the lock claw and the lock receiver.

[Operation] According to the above configuration, after the wire harness or the like is accommodated from the open portion inside the main body, the main body is covered with a lid to close the open portion, and the lock claw and the lock receiver are engaged. Let it. At this time, the stabilizer is compressed and elastically deformed between the main body and the lid, and retains an elastic force (elastic force) even after the lock claw and the lock receiver are engaged. As a result, the gap between the lock claw and the lock receiver is always closed by the elastic force of the stabilizer, and the play between the main body and the lid is suppressed.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view showing a state where the main body 10 and the lid body 20 of the protector are separated, FIG. 2 is a plan view showing the lid body 20, and FIG. It is shown in a perspective view.

1 to 3, the main body 10 has a shape in which a wire harness W is incorporated from an open portion 12 on the upper surface thereof as shown by a virtual line in FIG. Also the body
The bottom plate 10 is integrally formed with a tape winding protruding piece 16 extending further from the end in the longitudinal direction of the protector.

The lid 20 can be put on the main body 10 with the opening 12 closed. Two lock claws 24 are integrally formed on both sides of the lid 20, respectively. On the other hand, on both sides of the main body 10, lock receivers 18 are formed at locations corresponding to the respective lock claws 24 of the lid.

FIG. 4 shows an enlarged section of a part of FIG. As is clear from FIGS. 3 and 4, when the lid 20 is put on the main body 10, each lock claw 24 of the lid 20 is engaged with each lock receiver 18 of the main body 10. As a result, the main body 10 and the lid 20 are locked in an integral relationship with each other.

Now, at the position corresponding to both edges 14 of the open portion 12 of the main body 10, two stabilizers are respectively provided on the lid 20.
22 are formed. Each of the stabilizers 22 has a shape in which both ends thereof are integrally connected to the lid 20, and is expanded in an arc shape with a predetermined elastic force in a downward direction (a direction toward the main body 10).

FIGS. 5 (A) and 5 (B) are enlarged cross-sectional views showing an elastic deformation state of the stabilizer 22 when the lid 20 is put on the main body 10. FIG. That is, the stabilizer 22 before the lock claw 24 is engaged with the lock receiver 18 is not in contact with the edge 14 of the open portion 12 in the main body 10 as shown in FIG. In light contact.
Then, when each lock claw 24 is engaged with the lock receiver 18, the stabilizer 22 comes into contact with the edge portion 14, and FIG.
It is elastically deformed as shown by. Therefore, the stabilizer 22 in this state has an elastic force in the direction of pushing the lid 20 away from the main body 10.

When using the protector having the above configuration, a wire harness W in which a plurality of electric wires are bundled is incorporated into the main body 10 and then the lid 20 is covered so as to close the opening 12 of the main body 10. . As a result, each lock claw 24 of the lid 20 is
Engages with each lock receiver 18 of the main body 10 as shown in FIGS. 3 and 4. At this time, as described above, each stabilizer 22 of the lid 20 is brought into contact with the edge 14 of the main body 10 and elastically deformed as shown in FIGS. It has an elastic force in the direction of pushing the body 20 away from the main body 10.

That is, the lock claws 24 and the lock receivers 18 engage with each other while elastically deforming (compressing) the stabilizer 24. After the engagement, the gap between the lock receiver 18 and the lock claw 24 is absorbed by the elastic force held by the stabilizer 22, and the lock claw 24 is attracted to the lower surface of the lock receiver 18 (the second state). (See Fig. 4).

After the wire harness W is assembled inside the main body 10 and the lid 20 is put on the main body 10, the projecting piece 16 of the main body 10 and the wire harness W are both taped as shown in FIG. And wrap it. As a result, the wire harness W and the protector are integrated, and the protector is prevented from moving along the longitudinal direction of the wire harness W.

As mentioned above, although one Example of this invention was described, this invention is not limited to this Example, Various embodiments are considered.

For example, as shown in FIG.
May be formed integrally with the lid 20, and the other end may be a free end.

Further, as shown in FIG. 7, the stabilizer 22 may be formed on the edge 14 of the open portion 12 of the main body 10 so as to protrude upward (in the direction toward the lid 20) with an elastic force.

[Effects of the Invention] In the present invention, when the cover is put on the main body and the lock claw and the lock receiver are engaged with each other, the gap between the lock claw and the lock receiver is reduced by the elastic force of the stabilizer. The rattling between the main body and the lid is prevented even when subjected to vibration.
