JP 2010-233300 A

  By the way, in the case of the above-described wire binding member, it is necessary to simultaneously insert both ends of the band member into the insertion holes of the support column from the same direction while bundling a plurality of wires with the band member. Compared with the case where the part is fixed to the column part, the workability is lowered. In addition, since the band member generally tries to return to the state before being bent even after being wound around the electric wire and bent in a loop shape, in the case of the above-described electric wire binding member, even after the band member is bound, the band member There is a possibility that a gap is likely to be formed in a portion where both end portions of the two members start to be overlapped, and when the electric wire is pulled or the like, the electric wire enters the gap and loosening of the band member may occur.

  In this specification, the technique which suppresses the slack of the band member after binding is disclosed, forming a band member and the member which latches a band member separately.

  The technology disclosed in the present specification includes a band-shaped band member wound around the electric wire so as to bundle a plurality of electric wires at once, and a band holding portion provided separately from the band member, The band holding portion is assembled with one end of the band member, and holds the band member by locking with the first locking teeth provided on the band member, while holding the band member to the one side A first lock portion that is pulled out in a direction opposite to the direction in which the end portion is assembled, and the other end portion of the band member is inserted from a direction different from the direction in which the band member is pulled out in the first lock portion, and the band member And a second locking portion for locking the band member in a direction opposite to the insertion direction of the other end portion by locking with a second locking tooth provided on the other end.

According to the wire binding member having such a configuration, first, one end portion of the band member is assembled to the first lock portion of the band holding portion, so that one end portion of the band member is the first lock of the band holding portion. Held in the department.
Next, the band member is wound around the plurality of electric wires in a state where one end of the band member is held by the first lock part, and the other end of the band member is inserted into the second lock part. And the second lock portion can be locked. That is, it is possible to improve the workability of the band member assembling work as compared with the case where both ends of the band member are assembled to the band holding part, while the band member and the band holding part are separately configured.

  Moreover, according to said structure, the band pulled out from a 1st lock part is set by setting the insertion direction of the band member to a 2nd lock part in the direction different from the direction where a band member is pulled out from a 1st lock part. Since an angle can be given between the member and the band member drawn out from the second lock portion to the electric wire side, the directions of the band members drawn out from the first lock portion and the second lock portion are the same, and both bands Compared to the case where an angle cannot be provided between the members, it is not necessary to bend and band the band member abruptly, and it is possible to suppress the formation of a gap between the first lock portion and the second lock portion. . Thereby, it is possible to prevent the band members from being loosened even after the band members are bound.

The electric wire binding member disclosed by this specification is good also as the following structures.
The first lock portion includes a housing portion that has a support wall that extends straight along a pull-out direction of the band member on the inside, and the one end portion of the band member is inserted in an assembly direction, When the one end portion of the band member is inserted into the accommodating portion and elastically displaced by riding on the first locking teeth, and the band member is accommodated in the accommodating portion, the first engagement is achieved. It is good also as a structure provided with the elastic latching piece which supports the said band member so that it may follow along with the said support wall while it latches with a pawl.

According to such a configuration, even if the band member pulled out from the accommodating portion is bent, the band member is supported and arranged along the support wall, so that the band member is not inclined in the accommodating portion. The member can be pulled out straight.
That is, when the band member is tilted in the bending direction, the angle between the band member pulled out from the first lock portion and the band member pulled out from the second lock portion is reduced, so that the first lock portion and the first lock portion It is possible to prevent a gap from being easily formed between the two lock portions.

The band member is bent from the first lock portion toward the second lock portion, and the support wall is provided at a position on the opposite side of the housing portion from the direction in which the band member is bent. It is good also as a structure currently provided.
According to such a configuration, when the band member is bent, one end of the band member is pressed against the support wall to be supported, so that the band member is further prevented from being inclined in the bending direction. can do.

A plurality of the elastic locking pieces may be provided in the housing portion.
According to such a configuration, since the first locking teeth of the band member are locked by the plurality of elastic locking pieces and are prevented from coming off, the holding force of the first lock portion can be improved. That is, when the other end portion of the band member inserted into the second lock portion is pulled and a plurality of electric wires are tightened and bundled, the band member is prevented from being detached from the first lock portion by pulling the band member. can do.

A plurality of the first locking teeth are provided on any one of the wire contact surface on the side of the band member that contacts the wire and the non-contact surface of the band member on the side opposite to the wire contact surface. It is good also as a structure by which the some said 2nd locking tooth is provided in the other surface, and the mark is provided in any one of the said electric wire contact surface and the said electric wire non-contact surface.
When the arrangement of the locking teeth and the size of the locking teeth are different between the wire contact surface and the wire non-contact surface, if the wire contact surface and the wire non-contact surface are reversed, the band member can be assembled to the first lock portion. The band member cannot be inserted into the second lock portion. However, according to the above configuration, since the wire contact surface and the wire non-contact surface can be easily confirmed by checking the mark, the band contact surface and the wire non-contact surface are reversed. Incorrect assembly of the members can be suppressed.

The opening edge into which the band member is inserted in the band holding portion may be provided with a guide surface that is inclined inward toward the back.
For example, when it is difficult to process the band member, such as by tapering the end of the band member, the band member can be smoothly guided by being guided into the opening by the guide surface. Therefore, providing the guide surface is very effective.

  According to the technique disclosed in this specification, loosening of the band member after binding can be suppressed while forming the band member and the band holding portion for locking the band member separately.

  That is, although the band member 20 and the band holding portion 40 are individually configured, the band member 20 and the band holding portion 40 are integrally fixed before the band member 20 is wound around the electric wire W. The member 10 can be handled in the same manner as the wire binding member in which the band member and the band holding portion are integrally formed.

  Further, according to the present embodiment, as shown in FIG. 9, the band member 20 is pulled rightward from the accommodating portion 42 of the first lock portion 41 and bent in a loop shape in the clockwise direction. The first lock portion 41 is inserted into the band insertion hole 51 of the second lock portion 50 from the lower side different from the direction (right side) in which the band member 20 is pulled out. That is, since the angle R5 between the band member 20 drawn out from the first lock part 41 and the band member 20 drawn out from the second lock part 50 to the electric wire W side is set to a substantially right angle, for example, the first lock The band member 20 can be wound around the plurality of electric wires W without abruptly bending the band member 20 as compared to the direction in which the band member is inserted from the portion and the direction in which the band member is pulled out from the second lock portion to the electric wire side. It can be done.

The present embodiment is configured as described above. Next, the assembly procedure of the wire binding member 10 will be described, and the operation and effect of the wire binding member 10 will be described.
First, as shown in FIG. 7, a band holding part 40 and a long band member 20 are prepared. Here, the long band member 20 is configured by cutting out from a continuous band member wound around a reel.

  When the band holding part 40 and the band member 20 are prepared, the one end 20A of the band member 20 is inserted from the right side into the accommodating part 42 in the first lock part 41 of the band holding part 40. Here, it is necessary to assemble the band member 20 to the band holding part 40 so that the upper surface of the band member 20 becomes the electric wire non-contact surface 21. According to the present embodiment, the electric wire non-contact surface 21 of the band member 20 includes Since the mark groove 29 is provided, it is possible to easily determine which surface is the wire non-contact surface 21 only by confirming the mark groove 29. Thereby, it can suppress that the band member 20 is mistakenly assembled | attached to the accommodating part 42 in the state which reversed the electric wire contact surface 22 and the electric wire non-contact surface 21. FIG.

  By the way, the band member 20 cut out from the continuous band member wound around the reel is formed in the same width dimension over the entire length. For this reason, the end of the band member cannot be tapered, and a means for smoothly inserting the band member into the accommodating portion cannot be provided on the band member side.

  However, according to the present embodiment, the guide surface 43 is provided at the opening edge of the accommodating portion 42, and the band member 20 is accommodated by the guiding surface 43 when the band member 20 is inserted into the accommodating portion 42. Since it is guided in 42, the band member 20 can be smoothly accommodated in the accommodating portion 42.

Further, when the band member 20 is inserted into the accommodating portion 24, the plurality of first locking teeth 23 get over the first elastic locking piece 45, so that the band member 20 is firmly held. According to the present embodiment, a pair of gripping portions 30 are provided at both widthwise ends of the band member 20, and the pair of gripping portions 30 are arranged in the width direction. By gripping with fingers or the like from both sides in the direction, the band member 20 can be inserted into the accommodating portion 42 without grasping the triangular locking teeth 23 and 26 with a hand or bringing the fingers into contact with each other.
That is, according to the present embodiment, the band portion 20 can be assembled without damaging the finger or the like. For example, the band portion is held in a state where the band portion is gripped with the finger or the like in contact with the locking teeth. As compared with the case where the band portion 20 is inserted into the housing portion, the assembly workability of the band portion 20 can be improved.

  Further, when one end 20A of the band member 20 is inserted to the proper insertion position of the accommodating portion 42, the insertion of the band member 20 is completed, and the first locked surface 46 of the first elastic locking piece 45 is completed. Then, the first locking surface 25 of the first locking tooth 23 is locked in the left-right direction. Accordingly, the one end portion 20A of the band member 20 is retained and held in the housing portion 42, and the band holding portion is pulled out to the right from the housing portion 42 of the first lock portion 41. 40 is integrally fixed.

  Next, the band member 20 is bent in a loop shape in the clockwise direction so that the wire contact surface 22 of the band member 20 contacts the wire W, and the band member 20 is wound around the plurality of wires W. Then, the other end 20 </ b> B of the band member 20 wound around the plurality of electric wires W is inserted into the band insertion hole 51 in the second lock part 50 of the band holding part 40 from below. Since the guide edge 51 </ b> A is provided on the lower opening edge of the band insertion hole 51 as well as the opening edge of the accommodating portion 42, the band member 20 is smoothly inserted into the band insertion hole 51. be able to.

  When the band member 20 is inserted into the band insertion hole 51 and the other end 20B of the band member 20 protrudes upward from the band insertion hole 51, the other end 20B of the band member 20 is pulled upward. Then, as shown in FIG. 8, the loop-shaped band member 20 is squeezed to have a small diameter, and the second locked surface 54 of the second elastic locking piece 53 and the second locking teeth 26 are second. Since the locking surface 27 is locked in the vertical direction, the plurality of electric wires W are held together by the band member 20 in a bundled state.

  Finally, as shown in FIG. 9, by cutting the band member 20 protruding upward from the second lock portion 50, a bundle of wires W bundled by the wire binding member 10 is completed.

Here, according to the present embodiment, after the band member 20 is pulled rightward from the accommodating portion 42 of the first lock portion 41, the band member 20 is bent in a loop shape in the clockwise direction, and the band from the first lock portion 41. The member 20 is inserted into the band insertion hole 51 of the second lock portion 50 from below, which is different from the direction in which the member 20 is pulled out (rightward).
That is, as shown in FIG. 9, the angle R5 between the band member 20 drawn out from the first lock portion 41 and the band member 20 drawn out from the second lock portion 50 to the electric wire W side can be made to be a substantially right angle. For example, compared with the case where the direction in which the band member is pulled out from the first lock portion and the direction in which the band member is pulled out from the second lock portion to the electric wire side is set in the same direction, the band member 20 is sharpened. A plurality of electric wires W can be bundled without bending them. Thereby, it is suppressed that a gap is generated between the first lock part 41 and the second lock part 50 due to the band member 20 being bent suddenly, and the band member 20 is loosened after the band member 20 is bound. It can be prevented from occurring.

  By the way, when the other end portion 20B of the band member 20 protruding upward from the second lock portion 50 of the band holding portion 40 is pulled upward, the loop-shaped band member 20 has a small diameter, and one of the band members 20 Since the end 20 </ b> A is pulled obliquely to the lower right, there is a concern that one end 20 </ b> A of the band member 20 may be inclined obliquely to the lower right in the accommodating portion 42.

  However, according to the present embodiment, as shown in FIGS. 8 and 9, the first locked surface 46 of the first elastic locking piece 45 and the first locking teeth 23 on the wire contact surface 22 of the band member 20. Since the band member 20 is supported by the plurality of first elastic locking pieces 45 from below and arranged along the first support wall 44, the first locking surface 25 of the first locking surface 25 is locked in the left-right direction. When the band member 20 is strongly pulled obliquely to the lower right, one end 20A of the band member 20 is pressed against the support wall (upper inner wall) of the accommodating portion 42. In other words, the band member 20 is supported by the first support wall 44 that extends straight from side to side and is disposed on the upper side opposite to the side where the one end 20A is bent.

As a result, the angle between the band member 20 pulled out from the first lock portion 41 and the band member 20 pulled out from the second lock portion 50 to the electric wire W side is reduced, so that the first lock portion 41 and the first lock portion 41 It can suppress that a clearance gap produces between 2 lock parts 50.

  Further, according to the present embodiment, as shown in FIGS. 8 to 9, the plurality of first elastic locking pieces 45 are provided in the housing portion 42, and the holding force of the band member 20 in the first lock portion 41. Therefore, when the band member 20 is pulled, it is possible to prevent the band member 20 from being detached from the first lock portion 41 due to the pulling of the band member 20.

  By the way, in general, the surplus band member protruding from the band holding part is obstructed by other members and is therefore discarded. For this reason, in the case of an electric wire binding member in which the band member is formed integrally with the band holding portion or an electric wire binding member that simultaneously locks both ends of the band member to the band holding portion, although there is a difference in size, the band member Will end up being discarded.

However, according to the present embodiment, the first end portion 20A of the band member 20 is first fixed, and then the other end portion 20B of the band member 20 is fixed to the second lock portion 50. Even if the surplus band member 20 is cut, the surplus band member 20 can be used by being assembled to another band holding portion 40.
That is, according to the present embodiment, by preparing the band member 20 to be longer, the surplus band member 20 can be reused for the next band holding portion 40, so the length of the band member 20 is shortened. The band member 20 can be used without being discarded until it cannot be wound around the electric wire.
