Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp for holding the outer circumference of a bound object such as a corrugated tube or a wire harness.

[0002]

2. Description of the Related Art Conventionally, in this type of clamp, one end portion of a holding body and a lid body, which are formed in a substantially semi-circular shape, are connected to each other by a hinge portion. A lock receiving portion is formed on the other end of the holder, and a lock engaging portion is formed on the other end of the lid. By engaging the lock engaging portion with the lock receiving portion, the holding portion and the lid portion are held in a ring shape and hold the outer periphery of the object to be bound (for example, a corrugated tube).

[0003]

By the way, there are a plurality of kinds of objects to be bound depending on the outer diameter of the corrugated tube or the wire harness. On the other hand, it is necessary for the clamp to have an inner diameter corresponding to the outer diameter of the object to be bound when the holding portion and the lid are formed into a ring shape. Therefore, the same kind of clamp as the object to be bound must be prepared. I have to. The problem to be solved by the present invention is to make it possible to hold two or more types of bound objects having different outer diameters with one type of clamp,
This is to reduce the types of parts prepared in advance.

[0004]

Therefore, the clamp of the present invention is constructed as follows. That is, it is provided with a holding body and a lid body that are formed in a substantially semi-circular shape in order to hold the outer periphery of the object to be bound such as a corrugated tube and a wire harness, and one end portion of the holding body and the lid body is mutually opposite. A clamp which is connected by a hinge part and has a lock engaging part formed at one of the other ends and a lock receiving part formed at the other end thereof, wherein the lock engaging part is formed in the circumferential direction of the clamp. The lock receiving portion includes a guide hole into which the lock engaging portion can be inserted, and a lock engaging portion inserted into the guide hole, while the lock receiving portion includes two or more engaging step portions formed at predetermined intervals. And an engaging projection selectively engaged with one of the engaging step portions.

[0005]

In this structure, when the outer circumference of the object to be bound is held by the clamp, the object to be bound is positioned between the holding body and the lid, and the lock engaging portion of the lid locks the holding body. It inserts in the said guide hole in a receiving part. As a result, one of the two or more engaging step portions of the lock engaging portion engages with the engaging projection of the lock receiving portion according to the outer diameter of the bound object, and the outer periphery of the bound portion is Held by clamps. By selectively engaging the two or more engaging step portions of the lock engaging portion with the engaging protrusions of the lock receiving portion in this manner, at least two types of objects having different outer diameters can be obtained with one type of clamp. Can hold bundles.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. 1 is a front view showing a part of the clamp in section, FIG. 2 is a left side view of the clamp, and FIG. 3 is a right side view of the clamp. As shown in these drawings, the clamp is composed of a holding body 10 and a lid body 20 each having a substantially semi-circular shape. The holding body 10 and the lid body 20 are formed of an elastic material such as synthetic resin, and one end portions of the holding body 10 and the lid body 20 are connected to each other by a thin hinge portion 30.

Ribs 12 and 22 are integrally formed on the inner peripheral surfaces of the holding body 10 and the lid body 20, respectively, and locking legs are provided at substantially the middle portion (lower surface portion) of the outer peripheral portion of the holding body 10. 14 are integrally formed. The ribs 12, 22
As will be described later, when the outer periphery of the corrugated tube 60, which is an object to be bound, is held by the holding body 10 and the lid body 20, the corrugated tube 60 engages with the outer circumferential groove of the corrugated tube 60 and moves in the axial direction thereof. It is to regulate movement. In addition, the locking leg 14 is a corrugated tube 60.
It is for fixing the clamp by being inserted into a mounting hole (not shown) such as a vehicle body in a state where the outer periphery of is held by the holding body 10 and the lid body 20.

Now, in the lid 20, a free end portion opposite to the end portion joined by the hinge portion 30 is a lock engaging portion 40. On the other hand, the holder 10
In the same manner, the free end portion on the opposite side to the end portion which is also connected by the hinge portion 30 serves as a lock receiving portion 50. The lock engagement portion 40 includes two engagement step portions 42 and 43 formed at a constant interval in the circumferential direction of the lid body 20 (that is, the clamp). On the other hand, the lock receiving portion 50 includes a guide hole 52 into which the lock engaging portion 40 can be inserted, and an elastic piece 54 integrally formed with the holding body 10 so as to form one side surface of the guide hole 52. , And an engaging projection 56 integrally formed with the elastic piece 54 so as to project into the guide hole 52.

Next, a procedure for holding the outer periphery of the object to be bound by the clamp having the above-mentioned structure will be described. FIG. 4 is a perspective view showing a state in which the outer periphery of the corrugated tube 60 which is an object to be bound is held by a clamp. In order to obtain the state shown in this drawing, first, a part of the outer periphery of the corrugated tube 60 is placed inside the holding body 10 in the state shown in FIGS. Then, the lock engagement portion 40 is inserted into the guide hole 52 of the lock receiving portion 50 while covering the remaining outer peripheral portion of the corrugated tube 60 with the lid body 20 by utilizing the elastic deformation of the hinge portion 30.

By this insertion, the corrugated tube 60 out of the engaging step portions 42 and 43 of the lock engaging portion 40.
The one corresponding to the outer diameter of the lock receiving portion 50 passes through the engaging projection 56 while elastically bending the elastic piece 54 of the lock receiving portion 50, and simultaneously engages with the engaging projection 56. As a result, the outer periphery of the corrugated tube 60 is held by the clamp as shown in FIG. 4, and the ribs 12 and 22 of the holder 10 and the lid 20 engage with the outer peripheral groove of the corrugated tube 60 as described above. . After this holder 1
The locking leg 14 of No. 0 is inserted into a mounting hole (not shown) of a vehicle body or the like, and the work is completed.

FIG. 5 shows a clamp when the engaging step portions 42 and 43 of the lock engaging portion 40 are selectively engaged with the engaging protrusions 56 of the lock receiving portion 50.
That is, the engagement step portion 4 near the tip of the lock engagement portion 40.
When 2 is engaged with the engagement protrusion 56, the inner diameter of the clamp becomes large as shown in FIG. 5A, and when the other engagement step portion 43 is engaged with the engagement protrusion 56, 5 (B)
The inner diameter of the clamp becomes smaller as shown by. Therefore, this clamp can hold two types of corrugated tubes 60 having different outer diameters.

The number of the engaging step portions 42 and 43 of the lock engaging portion 40 is not limited as long as it is two or more. Further, contrary to the above-described embodiment, the lock engagement portion 40 may be formed on the holding body 10 and the lock receiving portion 50 may be formed on the lid body 20. In addition to the corrugated tube 60, the object to be bound includes a wire harness and a single electric wire.

[0013]

According to the present invention, since the inner diameter of the clamp can be set in two or more steps, one type of clamp can hold at least two types of objects to be bound having different outer diameters. It is possible to reduce the types.
