Description

  The present invention relates to a band clip.

  Conventionally, a band clip for binding a wire harness made of a bundle of electric wires is known. Such a band clip mainly comprises a long band part for fastening the wire harness, a band fixing part for fixing the band part in a tightened state, and a clip part for engaging with an object such as a vehicle panel. ing. The band clip is used by the operator as follows. That is, first, an operator winds a long band part around a wire harness, and after fixing the band part, the band part is fixed by the band fixing part. Thereby, a wire harness will be fastened and fixed to a band clip. In this state, the worker engages the clip portion with the vehicle panel or the like. By the above, a wire harness will be routed in the state fixed to the vehicle panel etc.

  A band clip for binding a plurality of wire harnesses has been proposed. This band clip has a plurality of band fixing portions, and after the band portion is wound around a certain wire harness, the band portion is fixed by a specific band fixing portion. At this time, an extra length portion exists in the band portion. For this reason, a plurality of wire harnesses can be bundled by winding the extra length portion of the band portion around another wire harness and fixing the band portion with a specific band fixing portion after the winding (see Patent Document 1). ).

  However, in the band clip described in the related art and Patent Document 1, an extra length portion is generated in the band portion. That is, in the conventional band clip, when the diameter of the wire harness is small, the length of the band part in the longitudinal direction is significantly longer than the outer periphery of the wire harness, and the tip of the band part is not fixed to the band fixing part. A long part will occur. Similarly, even in the band clip described in Patent Document 1, an extra length portion is generated after winding a plurality of wire harnesses. For this reason, problems such as deterioration in appearance due to the extra length portion occur. For this reason, the extra length portion is conventionally cut. However, when the extra length portion is cut, the extra length portion remains as dust.

Therefore, a band clip that eliminates the need for cutting the extra length has been proposed. This band clip has a hook at the tip of the band part, and even if the wire harness has a small diameter and an extra length portion is generated, by fixing the hook at the tip of the band part to a predetermined part of the band clip, The extra length is not required to be cut (see Patent Document 2).
JP-A-9-159064 JP-A-8-291807

  However, in the band clip described in Patent Document 2, when an extra length portion is generated, the hook must be pushed inside the band portion after winding, that is, between the band portion after winding and the wire harness. . For this reason, when a band part is tightly wound around a wire harness, the pushing operation | work of a hook is not easy and will lead to the fall of work efficiency. On the other hand, it is easy to push in the hook by tightening the band part weakly around the wire harness, but in this case, the binding force itself of the wire harness is weak and the wire harness causes abnormal noise due to vehicle vibration etc. It can be.

  The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to suppress a reduction in work efficiency while eliminating the need for cutting an extra length portion and to reduce noise. An object of the present invention is to provide a band clip capable of suppressing the occurrence of the above.

  The band clip of the present invention is an integrated band part for fastening a wire harness composed of a bundle of electric wires, a band fixing part for fixing the band part in a wound state, and a clip that engages an object. The band portion has an arch portion provided on the outer peripheral side in a state in which the band portion is wound, and the arch portion has an insertion hole through which the band portion can be inserted.

  In the band clip of the present invention, it is preferable that a plurality of arch portions are provided along the longitudinal direction of the band portion.

  In the band clip of the present invention, it is preferable that the arch portion has a protrusion on the inner wall of the insertion hole that presses the band portion when the band portion is inserted through the insertion hole.

  Further, in the band clip of the present invention, the band portion is provided at the front end of the band portion, and the head portion having an inclined structure in which the thickness gradually increases from the front end side toward the rear end side which is the opposite side. And the thickness of the rear end side of the head portion is preferably larger than the size of the insertion hole in the thickness direction.

  In the band clip of the present invention, the head portion has a locking portion on the inner peripheral side in a state where the band portion is wound, and the band portion is on the outer peripheral side in a state where the band portion is wound. Moreover, it is preferable that the to-be-latched part which can be latched by the latching | locking part is formed over the longitudinal direction.

  In the band clip of the present invention, the band portion has a plurality of groove portions formed in a direction orthogonal to the longitudinal direction over the longitudinal direction, and the band fixing portion and each arch portion are selected as the plurality of groove portions. It is preferable to have a tongue portion that engages with each other.

  According to the band clip of the present invention, since the band portion has an arch portion, and the arch portion has an insertion hole through which the band portion can be inserted, the band portion is fixed to the band fixing portion, and the extra length portion Even if this occurs, the extra length portion can be fitted along the wire harness by inserting the extra length portion through the insertion hole of the arch portion. Therefore, it is possible to eliminate the cutting of the extra length portion. Furthermore, since the arch part is provided on the outer peripheral side with the band part being wound, even if the band part is tightly wound around the wire harness, a hook or the like is pushed between the wire harness and the band part. There is no need, and a decrease in work efficiency can be suppressed. Furthermore, it is not necessary to tighten the band part weakly in consideration of the improvement of work efficiency, and it is possible to suppress a situation in which a noise is generated due to a gap between the wire harness and the band part.

  Moreover, since the arch part is provided with two or more over the longitudinal direction of a band part, the distance of the band part tip after winding a wire harness and either arch part becomes close. Thereby, after winding a wire harness, the distance of the front end side of a band part and an arch part becomes long, and the situation where the band part front end side will be in a free state can be suppressed.

  Moreover, since the arch part has a protrusion on the inner wall of the insertion hole, the band part inserted through the insertion hole is pressed and held by the protrusion, and the frequency with which the band part comes out of the insertion hole can be suppressed. .

  Further, since the band portion has a head portion that is provided at the front end of the band portion and has an inclined structure in which the thickness gradually increases from the front end side to the opposite rear end side, the insertion of the arch portion is performed. It is possible to facilitate the insertion into the hole. In particular, since the thickness of the rear end side of the head portion is larger than the thickness of the insertion hole in the thickness direction, even if a force is applied to the band portion to escape from the arch portion, the arch portion And the rear end side of the head part come into contact with each other, and the frequency with which the band part comes out of the insertion hole can be suppressed.

  Further, since the head portion has a locking portion and the band portion has a locked portion that can be locked to the locking portion in the longitudinal direction, the band portion is inserted into the insertion hole of the arch portion. By locking the locking part to the locked part, the leading end of the band part is fixed and the leading end side becomes free even if the arch part does not hold the leading end side of the band part. Deterioration of appearance can be suppressed. In particular, the locking portion is positioned on the inner peripheral side of the head portion with the band portion being tightened, and the locked portion is positioned on the outer peripheral side with the band portion being tightened. In this case, it is not necessary to push the head portion between the wire harness and the band portion, and it is possible to suppress a decrease in work efficiency.

  The band portion has a plurality of groove portions formed in a direction orthogonal to the longitudinal direction over the longitudinal direction, and the band fixing portion and each arch portion have tongue portions that selectively engage with the plurality of groove portions. . Therefore, the groove portion can be engaged with the tongue portion of the band fixing portion, and the groove portion can be engaged with the tongue portion of the arch portion by inserting the band portion into the insertion hole. Therefore, the band part can be fixed also in the arch part, and the frequency with which the band part comes out of the insertion hole can be suppressed. In particular, since the mating side engaged by the band fixing portion and the tongue portion of each arch portion is a plurality of groove portions formed in the band portion, the mating mating side can be made common.

In FIG. 3, the case where there are four arch portions 13 will be described as an example. After the band unit 10 is fixed by the band fixing unit 20, an operator or the like causes the head unit 12 to be inserted into the insertion hole 13 a 1 of the first arch unit 131 existing on the most rear end side. Thereafter, the operator or the like sequentially inserts the head portion 12 into the insertion holes 13a2 to 13a4 of the second to fourth arch portions 132 to 134. Thereby, as shown in FIG. 3, an extra length part will be settled along a wire harness. Moreover, since the head part 12 has an inclined structure, an operator or the like can easily insert the band part 10 into the insertion hole 13a.

  After the insertion, the worker or the like engages the locking portion 12a (see FIG. 1) of the head portion 12 with the locked portion 11b (see FIGS. 1 and 2) formed on the outer peripheral side of the band portion 10. . Thereby, the head part 12 provided at the tip of the band part 10 is fixed to the main body part 11. That is, the situation where the front end side of the band portion 10 is in a free state and the appearance is deteriorated is suppressed.

  In the state shown in FIG. 3, even if a force is applied in the direction in which the band unit 10 is removed from the arch part 13, the inclined structure, the tongue part 13 b of the arch part 13, the locking part 12 a of the head part 12, etc. Thus, the frequency with which the band portion 10 comes out of the insertion hole 13a is suppressed.
