Description

  The present invention relates to a binding structure for wiring members.

  Hereinafter, the background art will be described. In the following description, the symbols or names in parentheses are those in prior art documents. A conventional example of such a wiring member is described in JP-A-2008-251593 (Patent Document 1). In Patent Document 1, the wiring member is a conductive wire (insulated wire 8) in which the outer periphery of a conductor wire (stranded wire) is covered with an insulating coating material (Teflon (registered trademark)).

JP 2008-251593 A

  During the installation work of the conductive wire or when the conductive wire is installed at a place where vibration occurs, if the conductive wire moves with respect to another object around the conductive wire, the conductive wire rubs against the other object, causing the conductive wire to rub. There is a risk that the wire will break. Therefore, the wiring member is provided with a tubular protective tube disposed so as to cover the outer periphery of the conductive wire, and by covering the conductive wire with the protective tube, the conductive wire is protected, and the conductive wire is rubbed with another object. It is conceivable to adopt a configuration capable of reducing the possibility of disconnection of the conductive wire.

  However, the protective tube made of a woven sheet often does not have a large frictional force with the insulating coating material provided on the conductive wire, and the protective tube is simply arranged to cover the outer periphery of the conductive wire. However, even in the case where the protective tube is so arranged or the protective tube is bound together with the conductive wire by a binding body, the protective tube may move with respect to the conductive wire. Therefore, the conductive wire is exposed from the protective tube, and there is a possibility that the conductive wire may be broken at the exposed portion.

  Therefore, it is desired to realize a bundling structure of a wiring member that can bind a conductive wire so that it is difficult to move with respect to the protective tube.

  In view of the above, the characteristic configuration of the wiring material bundling structure includes a plurality of wiring materials and a binding body that binds them, and the wiring material is a conductive material in which the outer periphery of a conductor wire is covered with an insulating coating material. A protective tube formed of a tubular woven sheet arranged so as to cover the outer periphery of the conductive wire, wherein the binding body bundles a plurality of the wiring members and is provided outside the protective tube. The point is that they are united so that they are tied together.

  According to this characteristic configuration, a plurality of wiring members are bundled by the binding body and bound so as to be bound from the outside of the protection tube, compared with a case where one wiring material is bound from the outside of the protection tube by the binding body. In addition, the cross section of the protective tube at the binding portion of the binding body is likely to have a flat shape. Thereby, the contact pressure between the protective tube and the conductive wire at the binding portion of the binding body is likely to be partially increased. Therefore, it is possible to adopt a configuration in which the protection tube is hard to move with respect to the conductive wire. Further, the protective tube is formed of a tubular woven sheet, and the plurality of protective tubes formed of such a woven sheet are likely to have a large frictional force in a portion where their outer peripheral surfaces are in contact with each other, and are bound together. The protection tubes in the plurality of wiring members can be made in a state where it is difficult to move each other. This also makes it possible to provide a configuration in which the protective tube does not easily move with respect to the conductive wire.

1. Embodiment An embodiment of a wiring material binding structure will be described with reference to the drawings.
As shown in FIG. 1, the binding structure of the wiring member 1 includes a plurality of wiring members 1 and a binding body 2 that binds these. The plurality of wiring members 1 electrically connect the first member 3 and the second member 4. In the present embodiment, each of the plurality of wiring members 1 has a first end 1A, which is one end of the wiring member 1, connected to the first member 3, and is connected to the first end 1A of the wiring member 1. A second end 1 </ b> B, which is the opposite end, is connected to the second member 4.

  In the present embodiment, the first member 3 and the second member 4 are, for example, electric devices mounted on an inverter, and the wiring member 1 is used for electrically connecting a plurality of electric devices. In the present embodiment, the first member 3 is a smoothing capacitor, and the second member 4 is a discharge resistor.

  The first member 3 is attached to a first surface F1 of the case 6, and the second member 4 is attached to a second surface F2 of the case 6 that faces away from the first surface F1. Specifically, the case 6 has a peripheral wall 7 and a partition 8. The peripheral wall portion 7 forms a housing space S for housing the first member 3 and the second member 4. The partition section 8 is provided so as to partition the storage space S into a first space S1 that houses the first member 3 and a second space S2 that houses the second member 4. The partition part 8 has a first surface F1 facing the side where the first space S1 exists, and a second surface F2 facing the side where the second space S2 exists. The first member 3 is attached to the first surface F1 of the partition 8 and is located in the first space S1. The second member 4 is attached to the second surface F2 of the partition 8 and is located in the second accommodation space. In addition, the partition part 8 is equivalent to a wall material.

  The plurality of wiring members 1 are disposed from the first surface side A1 to the second surface side A2. In addition, an insertion hole 9 penetrating from the first surface A1 to the second surface A2 is formed in the partition 8. The plurality of wiring members 1 are inserted through the insertion holes 9. Then, the first end 1A of each of the plurality of wiring members 1 is connected to the partition 8 by setting the side on which the first surface F1 is present with respect to the center in the thickness direction of the partition 8 as the first surface A1. On the other hand, it is on the first surface side A1 and is connected to the first member 3. Further, the second end side 1B of the plurality of wiring members 1 is connected to the partition 8 by setting the side on which the second surface F2 is present with respect to the center in the thickness direction of the partition 8 as the second surface A2. On the other hand, it is on the second surface side A2 and is connected to the second member 4.

  As shown in FIGS. 2 and 3, the wiring member 1 is a conductive wire 13 in which the outer periphery of a conductor wire 11 is covered with an insulating coating material 12 and a tubular woven sheet arranged so as to cover the outer periphery of the conductive wire 13. And a protection tube 14 configured. The protection tube 14 covers the outer periphery of a portion of the conductive wire 13 except for both ends in the extending direction X of the conductive wire 13. That is, one end of the conductive line 13 in the extending direction X of the conductive line 13 is defined as a first conductive line end 13A, and an end of the conductive line 13 opposite to the first conductive line end 13A is defined as a first end. As the two conductive wire ends 13B, the outer periphery of the first conductive wire end 13A and the second conductive wire end 13B is not covered by the protective tube 14.

  The conductive wire 13 is formed by covering the outer periphery of one or more conductor wires 11 with the insulating coating material 12. In the present embodiment, the conductive wire 13 covers one conductor wire 11 with the insulating coating material 12. A first connector 16 for connecting the conductive wire 13 to the first member 3 is connected to the first conductive wire end 13A of the conductive wire 13. In the present embodiment, a round crimp terminal as a first connection body 16 is connected to the first conductive wire end 13A of the conductive wire 13. It is connected to one member 3. In the present embodiment, the second conductive wire end 13 </ b> B of the conductive wire 13 is directly connected to the second member 4. The first end 1A of the wiring member 1 is constituted by the first conductive line end 13A and the first connector 16, and the second end 1B of the wiring member 1 is constituted by the second conductive line end 13B. Have been. Note that a connector may be provided on the second conductive line end 13B in the same manner as the first conductive line end 13A. Further, the connection body connected to the end of the conductive wire 13 may be appropriately changed according to the member to be connected, and another connection body such as a connector may be connected instead of the crimp terminal.

  In the present embodiment, a glass tube formed by knitting a glass fiber is used as the protective tube 14. The protection tube 14 is divided into a first tube portion 14A and a second tube portion 14B. The first tube portion 14A and the second tube portion 14B are arranged so as to have an overlapping portion 17 that overlaps with each other in a partial area in the extending direction X of the conductive wire 13. In the illustrated example, one end of the first tube portion 14A is arranged so as to cover one end of the second tube portion 14B from the outside in the radial direction, and the overlapping portion 17 is formed.

  The binding body 2 bundles the plurality of wiring members 1 and binds them so as to bind them from outside the protection tube 14. The binding body 2 has a band portion 21, a band insertion portion 22, and a fixing portion 23. The band portion 21 is formed in a band shape, and its base is connected to the band insertion portion 22. The band portion 21 has a sufficient length that allows the plurality of wiring members 1 to be bundled and bound from the outside of the protective tube 14. The band insertion section 22 has an insertion hole 22A into which the band section 21 is inserted. In addition, the band insertion portion 22 has a one-way restriction mechanism that restricts the extraction while permitting the insertion of the band portion 21 into the insertion hole 22A. Specifically, a locking piece is provided so as to protrude from the inner surface of the insertion hole 22A. During insertion of the band portion 21, the locking piece elastically deforms and moves in the insertion direction of the band portion 21. However, when the band portion 21 is to be moved in the pull-out direction, the locking piece is locked by a locked piece (not shown) formed on the band portion 21, and the band portion 21 is pulled out. Regulate.

  The base of the fixing portion 23 is connected to the band insertion portion 22. In addition, the tip portion 23A of the fixing portion 23 is formed in a tapered shape. As shown in FIG. 1, when the binding body 2 is connected to the engagement portion 10 of the case 6, the fixed portion 23 can be inserted into the engagement portion 10 by elastically deforming the distal end portion 23 </ b> A. In the state where 23A has passed through the engaging portion 10, the distal end portion 23A returns to the natural state, so that the fixing portion 23 does not easily come off from the engaging portion 10. Thus, the binding body 2 is connected to the partition 8 by inserting the fixing part 23 into the engaging part 10. The partition 8 corresponds to a support member to which the binding body 2 is connected.

  When a plurality of wiring members 1 are bound by the binding body 2, the band portion is added to the overlapping portion 17 in a state where the first tube portion 14 </ b> A and the second tube portion 14 </ b> B are arranged so that the overlapping portion 17 is formed. The plurality of wiring members 1 are bound by winding 21. In this manner, the binding body 2 bundles and binds a plurality of wiring members 1 from outside the overlapping portion 17.

  As described above, by binding and binding the plurality of wiring members 1 by the binding member 2, in the binding portion, each wiring member 1 is bound in a direction in which the plurality of wiring members 1 are adjacent to each other. 2 easily deforms to be crushed. As a result, the cross section of the protection tube 14 of each wiring member 1 becomes flat, and the contact pressure between the protection tube 14 and the conductive wire 13 at the binding portion of the binding body 2 is likely to be partially increased. Therefore, it becomes difficult for the protection tube 14 to move with respect to the conductive wire 13. Further, as described above, the plurality of protective tubes 14 made of a woven sheet of glass fiber or the like are likely to have a large frictional force in a portion where the outer peripheral surfaces are in contact with each other. Therefore, in the binding portion of the binding body 2, the plurality of protection tubes 14 can be in a state where it is difficult for the protection tubes 14 to move with each other. This also makes it possible to provide a configuration in which the protective tube 14 is hard to move with respect to the conductive wire 13. Then, in the present embodiment, the binding body 2 in which the plurality of wiring members 1 are bound as described above is connected to the partition 8.

2. Other Embodiments Next, other embodiments of the binding structure of the wiring member will be described.

(1) In the above embodiment, the protection tube 14 is divided into the first tube portion 14A and the second tube portion 14B, but the invention is not limited to this. For example, the outer circumference of the conductive wire 13 may be covered by a single protective tube 14 without dividing the protective tube 14. When the protection tube 14 is divided into the first tube portion 14A and the second tube portion 14B, the first tube portion 14A and the second tube portion 14B are arranged so as not to have the overlapping portion 17. Is also good. Alternatively, the protection tube 14 may be divided into three or more.

(2) In the above embodiment, the plurality of wiring members 1 are bound and bound by the binding member 2 from the outside of the overlapping portion 17 of the protection tube 14, but the present invention is not limited to this. A portion other than the overlapping portion 17 in the protective tube 14 may be bound by the binding body 2.

(3) In the above embodiment, the binding body 2 is connected to the partition 8 to which the first member 3 and the second member 4 are attached, but the position where the binding body 2 is connected may be changed as appropriate. For example, the binding body 2 may be connected to another position such as the peripheral wall 7.

(4) In the above embodiment, the first member 3 is attached to the first surface F1, and the second member 4 is attached to the second surface F2 facing the opposite side to the first surface F1. The position where the two members 4 are attached may be changed as appropriate. For example, both the first member 3 and the second member 4 may be mounted on the same surface.

(5) In the above embodiment, the two wiring members 1 are bound by the binding member 2, but three or more wiring members 1 may be bound by the binding member 2. Further, in the above embodiment, only the plurality of wiring members 1 are bound by the binding member 2, but the plurality of wiring members 1 and other members may be bound together by the binding member 2.

(6) In the above embodiment, the plurality of wiring members 1 electrically connect the smoothing capacitor and the discharge resistor. However, the members to which the plurality of wiring members 1 are connected may be appropriately changed.

(7) The configurations disclosed in the above embodiments can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction occurs. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications can be appropriately made without departing from the spirit of the present disclosure.

3. The outline of the above-described embodiment will be described below.

  The binding structure of a wiring member includes a plurality of wiring members (1) and a binding body (2) that binds the wiring members (1), and the wiring member (1) has an insulating coating material on an outer periphery of the conductor wire (11). The binding body, comprising: a conductive wire (13) covered with (12); and a protective tube (14) formed of a tubular woven sheet arranged to cover the outer periphery of the conductive wire (13). (2) A plurality of the wiring members (1) are bundled and bound so as to be bound from the outside of the protection tube (14).

  According to this configuration, the plurality of wiring members (1) are bound by the binding member (2) and bound so as to be bound from the outside of the protective tube (14), so that one wiring member is bound by the binding member (2). As compared with the case where (1) is tied from the outside of the protection tube (14), the cross section of the protection tube (14) at the binding portion by the binding body (2) is more likely to be flat. Thus, the contact pressure between the protective tube (14) and the conductive wire (13) at the binding portion of the binding body (2) is likely to be partially increased. Therefore, it is possible to adopt a configuration in which the protection tube (14) is hard to move with respect to the conductive wire (13). Further, the protection tube (14) is formed of a tubular woven sheet, and the plurality of protection tubes (14) formed of such a woven sheet have a frictional force in a portion where their outer peripheral surfaces are in contact with each other. Can easily be increased, and the protective tubes (14) in the plurality of bound wiring members (1) can be hardly moved together. This also makes it possible to provide a configuration in which the protective tube (14) is difficult to move with respect to the conductive wire (13).

  Here, the protection tube (14) is divided into a first tube portion (14A) and a second tube portion (14B), and the first tube portion (14A) and the second tube portion (14B). Is arranged so as to have an overlapping portion (17) overlapping with each other in a partial region in the extending direction (X) of the conductive wire (13), and the binding body (2) is provided with the overlapping portion (17). It is preferable that a plurality of the wiring members (1) are bundled and bound from the outside of ()).

  According to this configuration, the first tube portion (14A) and the second tube portion (14B) can be bound to the conductive wire (13) by one binding body (2). Therefore, when the protection tube (14) is divided and the first tube portion (14A) and the second tube portion (14B) are individually bound to the conductive wire (13) by the binding body (2). In comparison, the man-hour and the number of components for binding a plurality of wiring members (1) can be reduced, and the cost can be reduced.

  Also, it is preferable that the binding body (2) is connected to a support member (8).

  According to this configuration, since the binding body (2) is connected to the support member (8), the binding body (2) can be made difficult to move with respect to the support member (8). This makes it difficult for the conductive wires (13) bound by the binding body (2) to move with respect to the support member (8). Therefore, the effect of reducing the possibility that the conductive wire (13) is broken due to the conductive wire (13) rubbing against the support member (14) can be enhanced.

  The plurality of wiring members (1) electrically connect the first member (3) and the second member (4), and the first member (3) is connected to the first member (3) of the wall member (8). The second member (4) is attached to a surface (F1), and the second member (4) is attached to a second surface (F2) of the wall member (8) facing the opposite side to the first surface (F1), and a plurality of the members are provided. It is preferable that the wiring member (1) is disposed from the first surface side (A1) to the second surface side (A2).

  In this configuration, the plurality of wiring members (1) are connected from the first surface side (A1) to the second surface side (A2) in order to electrically connect the first member (3) and the second member (4). , It is in a state where it is easy to come into contact with the wall member (8) between the first member (3) and the second member (4). However, by bundling the plurality of wiring members (1) with the binding body (2) and binding them so as to bind them from the outside of the protection tube (14), the conductive wire (13) moves with respect to the protection tube (14). The portion of the conductive wire (13) that may come into contact with the wall material (8) can be appropriately protected by the protective tube (14). Therefore, even with such a configuration, it is possible to reduce the possibility of disconnection due to the conductive wires (13) in the plurality of wiring members (1) coming into contact with the wall member (8).

  The technology according to the present disclosure can be used for a binding structure of a plurality of wiring members.
