Description

  The present invention relates to a tightening band mounting structure, and more particularly, to a tightening material having a long side portion and a short side portion in a cross-sectional outer shape where the band-like band is tightened, particularly in a long side portion. It can be tightened and fixed without lowering.

  Conventionally, as shown in FIGS. 8A to 8C, a resin boot (a material to be tightened) 160 that covers a constant velocity joint 150 for a vehicle is tightened in Japanese Patent Application Laid-Open No. 2004-301140 (Patent Document 1). As the tightening band 100, a band that can absorb the variation in the intersection of the objects to be fastened without lowering the surface pressure of the band has been proposed. The tightening band 100 is a band to be tightened by being wound around a material to be tightened having a circular cross section, and is formed into a substantially perfect ring shape by superimposing both ends of a curved metal strip 110, and a locking claw provided at both ends. Is inserted and locked in the locking hole. The cross correction member 120, which is a separate member, is fixed to the mounting recess 111 (or mounting hole) provided in the middle portion of the metal band 110 in the length direction with an adhesive or an adhesive tape so that the band thickness is thicker than both ends. It is made into a convex shape partially, and it is made to provide the restoring force for the edge parts of the metal strip 110 to return relatively to a diameter-expanding direction, and to latch.

  According to the above-described conventional configuration, the tightening band 100 is tightened in a substantially circular ring shape, so that the tightening band 100 provides a uniform tightening force over the entire circumference of the material to be tightened having a circular cross section. can do.

  Recently, high-voltage cables routed in electric vehicles and hybrid vehicles are covered with a shield member made of metal braided wire, and one end of the shield member is covered with a shield shell of a connector connected to the high-voltage cable and tightened with a metal band. In addition, the other end of the shield member is put on a metal tube covered with a high voltage cable and fixed with a metal band. The shield shell and the metal tube covering the shield member may have a rectangular or elliptical outer shape in cross section.

  When the cross section is rectangular or elliptical and has a pair of long sides and short sides like the shield shell and metal tube, the shield member and the fastening band to be covered also have the long sides and short sides in the attached state. It becomes a shape. In such a shape, the tightening force by the tightening band is weaker in the long side portion than in the short side portion, and a uniform tightening force cannot be applied to the entire circumference. In particular, when the long side is a rectangle or ellipse, the fastening material cannot be applied to the entire length of the long side to provide the same surface pressure as the short side. The surface pressure varies. Therefore, the noise removal effect may be reduced in the portion where the end of the shield member is detached from the outer peripheral surface of the shield shell or the metal tube at the long side where the tightening force is weak and the shield member is removed.

  The fastening band described in the above-mentioned Patent Document 1 is only designed to absorb the intersection by attaching the cross-absorbing member 120 at one location in the length direction of the band to increase the thickness. When the fastening material is rectangular or elliptical in cross section and has a long side portion, it is not possible to apply a uniform fastening force over the entire circumference of the material to be fastened.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show a first embodiment.

The fastening band 1 used in the first embodiment is a caulking metal fastening band, and the band body 2 is formed from a thin strip-like thin plate made of a stainless steel plate having spring properties. The band body 2 is wound around the outer surface of the fastening material 20 having a rectangular cross-sectional shape, and the first overlapping portion 5 and the second overlapping portion 6 provided at both ends in the length direction of the band body 2 are overlapped on the inner and outer periphery. In this state, the locking claws provided in the first and second overlapping portions 5 and 6 are locked in the locking holes and temporarily locked in a rectangular frame-shaped ring. The caulking portion 3 provided in the caulking portion is caulked and temporarily locked, and the fastening band 1 is fastened and fixed to the material 20 to be fastened.
In addition, although the to-be-fastened material 20 in this embodiment is processed into circular at the four corners and is not a perfect rectangle, in the present invention, such a shape is also included in the to-be-fastened material having a rectangular cross section. And

  The band main body 2 of the tightening band 1 has a pair of long side portions 2a and 2b and short side portions 2c and 2d that connect both ends of the long side portions 2a and 2b in a state of being temporarily locked in the rectangular frame shape. Bending is performed in advance so as to form an oval ring having a cross section. One short side 2c is formed by temporarily locking the first and second overlapping portions 5 and 6 at both ends of the band body 2 on the inner and outer peripheries, and in the center of the other short side 2d. A fastening portion 3 is provided. In addition, a step is generated at the inner peripheral end portion of the overlapped portion of the first and second overlapping portions 5 and 6, and a gap is generated between the material to be fastened 20. In such a place where the gap is generated, the fastening force is reduced because the fastening band 1 cannot be tightly attached to the material 20 to be fastened.

  As shown in FIG. 1 to FIG. 3, the holding portion is formed by bending the portion that becomes the pair of long side portions 2 a and 2 b so that the central portion in the length direction is an arc shape that protrudes outward most. 2h and 2i are provided. Inclusions 21 and 22 having a shape that fits in the holding portions 2h and 2i are provided. The inclusions 21 and 22 are formed of rubber or elastomer, and an adhesive is applied to the arc-shaped outer surfaces of the inclusions 21 and 22 or the inner surfaces of the holding portions 2h and 2i, so that the inclusions 21 and 22 are held in the holding portions 2h and 2i. It is fixed inside. In this state, the flat surfaces 21a and 22a of the inclusions 21 and 22 are arranged so as to slightly protrude from the both side flat portions 2a-h and 2b-i of the long side portions 2a and 2b, and the inclusions 21 and 22 are band-tightened. When compressed at times, the two side flat portions 2a-h, 2b-i are flat and continuous, and are in close contact with the entire outer length of the pair of long side portions 20a, 20b of the material 20 to be fastened. , 20b so that a tightening force is applied to the entire length.

  Further, as shown in FIGS. 1 (B) and 3 (B), the first superposition 5 of the band main body 2 is an outer periphery and the second superposition portion 6 is an inner periphery, and is superposed on the inner and outer peripheries. Each of the first and second overlapping portions 5 and 6 is provided with one locking claw 7 and 8 on the tip side, and one locking claw 7 and 8 is spaced apart from each other in the length direction. Holes 9 and 10 are provided. The locking claw 7 of the first overlapping portion 5 positioned on the outer peripheral side is bent downward, while an upward bulging portion 10a is provided at the end of the locking hole 10 of the second overlapping portion 6 on the inner peripheral side, The claw 7 is inserted into the locking hole 10 so that it can be locked to the lower surface of the bulging portion 10a. Further, the locking claw 8 of the second overlapping portion 6 is bent upward and inserted into the locking hole 9 made of a long hole of the first overlapping portion 5, and the locking claw 8 is engaged when the caulking portion 3 is caulked. The inside of the stop hole 9 is movable, and is locked to the leading edge 9 e of the lock hole 9.

  A locking portion between the locking claw 7 and the locking hole 10 is a first locking portion A, and a locking portion between the locking claw 8 and the locking hole 9 is a second arc portion B. Since the first and second overlapping portions 5 and 6 are positioned in the short side portion 2c, both the first locking portion A and the second locking portion B are in a temporarily locked state and a fully locked state. However, it is located in the short side 2c. The dimension (L) at the time of temporary coupling between the first latching part A and the second latching B is a dimension that allows an operator to couple by one-hand work, for example, 5 cm or less.

  In addition, a positioning hole 11 is provided in the central portion between the locking claw 7 and the locking hole 9 of the first overlapping portion 5, and the positioning protrusion 12 that is loosely inserted into the positioning hole 11 is connected to the locking claw of the second overlapping portion 6. 8 and the locking hole 10. The fitting position between the positioning projection 12 and the positioning hole 11 is located at the approximate center of the short side portion 2c, and is opposed to the caulking portion 3 provided at the center of the other short side portion 2d.

  Furthermore, while providing the U-shaped piece 13 provided with the notch groove 13u in the center at the front-end | tip of the 2nd superposition | polymerization part 6 of the inner peripheral side, the 1st superposition | polymerization part 5 of the outer peripheral side of the part which this U-shaped piece 13 overlaps is provided. The U-shaped piece 13 and a stepped protrusion 14 that is continuous in a plane are provided by being inserted into the notch groove 13u. Thereby, the outer peripheral surface of the fastening band 1 which contacts the to-be-fastened material 20 is made to continue without a level | step difference.

  The caulking portion 3 provided at the center of the short side portion 2d is projected outward in a U-shape, and the U-shaped side portions 3a and 3b are sandwiched by caulking jigs so as to be easily caulked. . Further, an inwardly bulging portion 3d is provided in the central portion 3c, and as shown in FIG. 3 (B), it is easily folded and overlapped during caulking. In the caulking portion 3, the tightening force tends to decrease because the caulking portion 3 cannot be in close contact with the material 20 to be fastened at the center portion 3 c.

Next, a method for attaching the fastening band 1 will be described.
In this embodiment, as shown in FIG. 4 and FIG. 5, the end of the shield member 31 made of a metal braided wire that covers the high-voltage cable 30 routed in the electric vehicle or hybrid vehicle is connected to the end of the high-voltage cable. The fastening band 1 is used to cover the outer surface of the metal connector shell 32 of the connector to be secured and to fasten and fix the shield member 31 to the outer peripheral surface of the connector shell 32. Since the outer shape of the connector shell 32 covering the flexible shield member 31 is rectangular, the material to be tightened 20 comprising the connector shell 32 and the shield member 31 tightened by the tightening band 1 is shown in FIG. The to-be-tightened material 20 whose outer shape shown is rectangular.

  The tightening band 1 holds the inclusions 21 and 22 by fixing them in the holding portions 2h and 2i. The fastening band 1 has an outer periphery of a shield member 31 that becomes a material to be fastened 20 with the first and second overlapping portions 5 and 6 at both ends opened in a substantially heart shape as shown in FIG. Cover the surface. On the outer surface of the short side portion 20c of the material to be fastened 20, the second overlapping portion 6 is overlapped on the inner periphery, the first overlapping portion 5 is overlapped on the outer periphery, and the crimp portion 3 is positioned on the outer surface of the opposing short side portion 20d, Further, the flat surfaces 21a and 22a of the inclusions 21 and 22 held by the holding portions 2h and 2i and the flat portions of the long side portions 2a and 2b are placed in contact with the outer surfaces of the long side portions 20a and 20b, respectively.

  Next, the first overlapping portion 5 is overlapped on the outer surface of the second overlapping portion 6 of the band body 2, the fastening band 1 is formed in a ring shape, and the locking claw 7 is inserted and locked into the locking hole 10 to lock the first engagement portion. The stop portion A is temporarily locked, and the locking claw 8 is inserted and locked into the locking hole 9 to temporarily lock the second locking portion B. In the second locking portion B, the locking claw 7 is positioned at a substantially central portion of the locking hole 9 formed of a long hole, and can be moved to the side end. Further, the positioning projection 12 is loosely inserted into the positioning hole 11. The temporary locking of the first and second locking portions A and B has a short dimension (L) between the first and second locking portions A and B, and the insertion lock even if the band body 2 is not pulled strongly. Since it can be stopped, the worker can carry out continuously by one-handed work.

  In the temporarily locked state shown in FIG. 3A, the shield member 31 of the material to be tightened 20 is attached to the connector shell 32 with the tightening band 1, but the tightening force of the tightening band 1 is increased. In order to firmly fix the shield member 31 to the connector shell 32 so as not to move, the caulking portion 3 of the tightening band 1 is caulked using a caulking jig (not shown). By the caulking operation, the first and second overlapping portions 5 and 6 at both ends in the length direction of the band body 2 are pulled toward the caulking portion 3 at the center position in the length direction of the band body 2. Therefore, the locking claw 7 and the locking hole 10 and the locking claw 8 and the locking hole 9 that are locked by the first and second locking portions A and B are indicated by arrows in FIG. As described above, both are pulled in opposite directions to increase the locking force.

In addition, the long side portions 2a and 2b of the band body 2 are also pulled toward the caulking portion 3 in the direction in which the length is reduced, and the outer shape is formed into an arc shape with inclusions 21 and 22 interposed therebetween. It can be added without loosening the tightening at the central portion in the length direction of the portions 2a and 2b.
More specifically explaining this action, if the inclusions 21 and 22 are not interposed, the boundary portions of the long side portions 2a and 2b and the short side portions 2c and 2d of the band main body 2 serve as fulcrums, The tightening force is concentrated in this part. For this reason, the band main body 2 is difficult to be brought into close contact with the outer peripheral surface of the material to be fastened 20 particularly at the long side portions 2a and 2b where the distance between the fulcrums is long, and the fastening force is weakened. Therefore, in order to eliminate the fulcrum or weaken the function of the fulcrum, it is desirable to fasten and fix the band body 2 in a state closer to a perfect circle.
Therefore, when the inclusions 21 and 22 are interposed and the long side portions 2a and 2b of the band body 2 are formed in an arc shape as in the present embodiment, the overall shape of the band body 2 is closer to a perfect circle. Even on the rectangular outer surface of the shell 32, the shield member 31 can be clamped and fixed substantially uniformly over the entire circumference by the clamp band 1.

  Further, the caulking portion 3 is a portion where the tightening force is relatively weak in the band body 2, but the caulking portion 3 is not the long side portions 2a and 2b where the tightening force is difficult to act. Since the short side portion 2d is provided, the tightening force of the tightening band 1 can be equalized.

  Further, when the both sides of the band body 2 are overlapped and locked, a step is generated, and a gap is generated between the tightening band 1 and the material to be tightened 20, but the first locking portion A and the Since the two locking portions B are positioned, a gap due to the step is not generated at the long side portions 2a and 2b, and a decrease in the tightening force at the long side portions 2a and 2b can be prevented.

  Thus, in this embodiment, the band main body 2 of the metal fastening band 1 is wound around the shield member 31 that covers the connector shell 32 having a rectangular cross section, and the inclusions provided on the pair of long side portions 2a and 2b. 21 and 22 are pressed against the outer surface of the shield member 31, and the outer shapes of the long side portions 20a and 20b of the material to be fastened 20 are pseudo-arc-shaped. Therefore, the tightening force does not decrease the tightening force of the tightening band that decreases at the long side portions 2a and 2b, and the tightening force is applied over the entire circumference of the pair of long side portions 20a and 20b and the short side portions 20c and 20d. Can be given more evenly. As a result, the shield member 31 of the material to be tightened 20 is firmly tightened and fixed to the connector shell 32 having a rectangular cross section with the tightening band 1, and the shield member 31 comes off on the long side portion side, and the shield function is partially lowered. Can be prevented.

  In many cases, a high voltage cable routed in an electric vehicle or a hybrid vehicle is covered with a shield member 31 made of the metal braided wire so as not to generate external noise. The shield member 31 is made of a metal braided wire, and the resin fastening band 1 that is widely used as a fastening member of a wire harness routed in an automobile has low strength. Instead of 1, the metal fastening band 1 of the present invention can be suitably used.

  Moreover, since the length which overlaps the 1st, 2nd superposition | polymerization part 5 and 6 of the band main body 2 is made into the one short side part 2c, the whole length of the band main body 2 can be shortened, and it is material cost by that much. Can be reduced. And since the 1st, 2nd latching | locking part A and B located in the overlapping part of the 1st, 2nd superposition | polymerization part 5 and 6 approach, an operator can carry out 1st, 2nd latching | locking part A, The locking operation of B can be performed continuously, the workability of attaching the fastening band 1 is improved, and the productivity can be improved.

FIG. 6 shows a modification of the first embodiment.
In the modified example, the holding portions 2h and 2i provided on the pair of long side portions 2a and 2b are cut and raised to provide needle-like holding protrusions 2s and 2t, and the inclusions 21 and 22 provided on the holding portions 2h and 2i Touch and hold. With this configuration, the inclusions 21 and 22 can be stably held at appropriate positions without using an adhesive. Since other configurations and operations are the same as those of the first embodiment, description thereof is omitted.

FIG. 7 shows a second embodiment.
In the second embodiment, the tightened member 40 having an elliptical cross section is tightened by the tightening band 1. Specifically, the high-voltage cable 30 extends through the metal pipe 41 made of aluminum having an elliptical cross section in the underfloor wiring region of the high-voltage cable shown in FIG. One end of the shield member 31 made of the metal braided wire is covered, and a fastening band is used to fasten and fix the shield member 31 to the metal tube 41. Since the shield member 31 tightened to the metal tube 41 has an elliptical cross section, the tightening band 1 is also a ring having an elliptical cross section in the tightened state.
In addition, although the to-be-clamped material 40 in this embodiment is a linear part in a long side part and a short side part, and it is not a perfect ellipse, in this invention, such a shape is also oval in cross section. It shall be included in the material to be tightened.

A metal fastening band similar to that of the first embodiment is used as the fastening band, and the metal tube 41 is bent in advance into a shape along the cross-sectional ellipse shape, and is formed of a pair of arc sides opposed in the long axis direction. Of the side portions 2c and 2d, the first and second overlapping portions 5 and 6 at both ends of the band body 1 are provided on one short side portion 2c. The tightening band 1 is formed by superimposing the first and second overlapping portions 5 and 6 of the tightening band 1 on the outer surface of one short side portion 40c of the material to be fastened 40, and the first and second coupling portions A and B. Is located in the region of the short side portion 40c.
Similar to the first embodiment, holding portions 2h and 2i that hold the inclusions 21 and 22 are provided to protrude outwardly in the portions that become the pair of long side portions 2a and 2b.
Since other configurations, tightening procedures, and operational effects are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  In the third embodiment, the holding portions 2h and 2i protruding outward are not provided in the portions that become the long side portions 2a and 2b of the metal band main body 2, and are continuously provided in a flat plate shape. Only this point is different from the fastening band 1 of the first embodiment, and the other parts have the same configuration.

On the other hand, inclusions made of rubber or elastomer are fixed to the portion to be the long side portion of the material to be tightened with an adhesive, and the outer shape of the linear long side portion is formed in an arc shape.
Thus, even if the inclusions are fixed to the long side portion of the material to be tightened to form an arc shape, as in the first embodiment, the tightening force of the tightening band at the long side portion is not reduced, The tightening force can be applied evenly over the circumference.

  In the fourth embodiment, an adhesive tape made of a resin tape made of rubber tape or acetate is wound around a material to be fastened having a rectangular cross section. The pressure-sensitive adhesive tape to be wound is made of a pressure-sensitive adhesive tape in which a pressure-sensitive adhesive is applied to the surface of a tape base material made of the rubber or resin having a large thickness and flexibility. The adhesive tape is wound around the outer peripheral surface of the material to be tightened a plurality of times until the required thickness is reached. The inclusion may be formed by laminating a plurality of adhesive tapes so as to form a mountain shape on a pair of long sides of the material to be fastened.

  The fastening band is attached to the outer peripheral surface of the adhesive tape using a metal fastening band that is different from the fastening band of the first embodiment only in that the inclusion holding portion is not provided. In this case, when a caulking portion provided on the metal band is caulked and a strong tensile force is applied to the band main body, the adhesive tape can be compressed and a strong clamping force can be applied. And even if the inclusion is formed with the adhesive tape on the long side portion of the material to be fastened in this way, the tightening force of the fastening band at the long side portion is not reduced as in the first embodiment. The tightening force can be evenly applied over the entire circumference.

In the fifth embodiment, the fastening band is made of resin, the basic shape is the same shape as a commonly used resin fastening band, and the band protrudes from a box-shaped body provided with a through hole, The band is wound around a material to be tightened, inserted into a through hole, and a locking claw projecting from the inner surface of the through hole is locked with a sawtooth locking groove provided on the band. The body of the tightening band is attached so as to be positioned on one short side of the material to be tightened.
In addition, a thick portion having an outer surface formed in an arc shape is integrally formed at a portion located on the pair of long side portions of the band main body.
As described above, it is possible to prevent the tightening band from being reduced in the long side portion even if the thick portion is integrally provided in the band body and the outer shape is formed in an arc shape. . Further, by providing the thick portion integrally with the band main body, the step of providing inclusions as in the other embodiments can be omitted, so that the tightening band can be attached more efficiently.

  In addition, as a modification of the fifth embodiment, in a metal fastening band, a configuration in which thick portions are integrally provided in portions located on a pair of long side portions of the band main body may be employed. In this case, the same effects as those of the fifth embodiment are obtained.

The present invention is not limited to the embodiment described above, and for example, the following embodiments are also included in the technical scope of the present invention.
(1) The to-be-fastened materials 20 and 40 in the said embodiment were the rectangle by which the four corners were processed circularly about the cross-sectional shape, or the ellipse shape which has a linear part, but the to-be-fastened material of this invention The cross-sectional shape may be a complete rectangle with four corners or a complete ellipse with no straight line.

(2) The band-shaped band body 2 of the fastening band 1 used in the present invention may be made of metal, resin, or leather. Moreover, if the latching | locking part provided in the band main body 2 is a structure which can latch a latching | locking part and a to-be-latched part mutually, it will not be limited to the said embodiment.

(3) In the first embodiment, the long side portions 2a and 2b of the fastening band 1 are bent in advance to form the holding portions 2h and 2i. However, the fitting portions 2h and 2i are bent from the beginning. Instead of forming, it may be bent by interposing inclusions and tightening.

(4) The inclusions 21 and 22 in the above embodiment are applied by applying an adhesive to the inner surfaces of the holding portions 2h and 2i or the fastening materials 20 and 40, or are held by the needle-like holding protrusions 2s and 2t. However, in the present invention, it may not be held with the aid of an adhesive or a holding projection, but may be held only by the tightening force of the band body 2.

(5) In the above embodiment, the outer surface has the arcuate inclusions 21 and 22 and the thick portion. However, in the present invention, the inclusions 21 and 22 and the thick portion themselves have the arcuate outer surface. It is not limited to what has. Therefore, for example, even if the inclusion does not have an arc outer surface such as a prismatic shape, the band main body 2 positioned on the long side in the tightened state becomes an arc shape, so that the entire shape of the tightening band 1 becomes a perfect circle. If it is possible to approach and equalize the tightening force, inclusions and thick portions having such shapes can be applied.

(6) In the above embodiment, the inclusions 21 and 22 and the thick part are provided on both of the pair of long sides, but even if the inclusions are provided only on one of the pair of long sides, A tightening force can be effectively applied to the long side portion, and such a form is also included in the present invention.
