  Next, the binder, the wire harness, and the method of manufacturing the wire harness according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments.

(Sheet)
The sheet 10 used in the binding device according to the present disclosure is basically composed of a base 12 and a self-adhesive layer 14 provided only on one side of the base 12 (see FIG. 2). The sheet 10 is provided with the self-adhesive layer 14 over the entire surface of the substrate 12 and has flexibility capable of bending and deforming in its own thickness direction. The substrate 12 may be either a single layer structure made of one material or a multilayer structure in which a plurality of materials are stacked, and if it has a multilayer structure as shown in the enlarged view of FIG. It is preferable to comprise from 13a and the shock absorbing material layer 13b, In this case, the protective layer 13a is exposed to the outer side, comprises the surface of the sheet | seat 10, and the self-adhesive layer 14 is provided in the shock absorbing material layer 13b side.

  The material of the protective layer 13a of the base 12 is preferably a resin having a certain degree of extensibility, and for example, a film of polyethylene, polyamide, polypropylene, polyethylene terephthalate or the like is used. As a film forming the protective layer 13a, a stretched film (uniaxial stretching, biaxial stretching, etc.), a non-stretched film, a laminate of a stretched film and a non-stretched film, or the like can be used, depending on the characteristics required for the protective layer 13a. And may be used as appropriate. A stretched film can be thin and has excellent rigidity and abrasion resistance, and a non-stretched film is particularly excellent in flexibility. In addition, the lamination method of a stretched film and a non-stretched film is not specifically limited, It is a well-known method, Wet lamination (using water-based adhesive or water-dispersed adhesive), dry lamination (solvent-based adhesive or reaction system) A laminating method using an adhesive such as an adhesive, a hot melt lamination (hot melt adhesive), an extrusion laminating method, or the like can be employed.

  The buffer material layer 13b of the base 12 may be a foamed or porous sheet having fine cells in a synthetic resin. The synthetic resin used as the raw material is not particularly limited, and, for example, polyolefin resin (mainly polyethylene (PE) or polypropylene (PP)), polyurethane resin (PUR), polystyrene resin (PS), etc. can be adopted. is there. In addition, as the buffer material layer 13b, a polyolefin resin foam or a polyurethane resin foam is preferable. The bubble structure of the buffer layer 13b is preferably a communication structure in which the bubbles are connected to each other, but the bubbles may be independent structures independent of each other. When a foam is used as the buffer material layer 13b, the expansion ratio is in the range of 2 times to 100 times, preferably 10 times to 30 times. The thickness of the buffer material layer 13b is preferably in the range of 0.3 mm to 6 mm, and more preferably in the range of 0.5 mm to 3.0 mm.

  The self-adhesive layer 14 has self-adhesiveness. Here, self-adhesiveness means that only the self-adhesive layers 14 and 14 exhibit adhesiveness, and the self-adhesive layers 14 and 14 of the same material are adhered to each other by overlapping and lightly pressing them. Join with moderate strength. For example, even when the self-adhesive layer 14 is in contact with anything other than the self-adhesive layer 14 such as the base 12 and the wiring H, its own adhesiveness does not work. The self-adhesive layer 14 may be, for example, a natural rubber latex as a base resin, a terpene resin as a tackifier (tackifier), a rosin ester resin, a petroleum resin (aliphatic or aromatic), or phenol What mixed | blended a system antioxidant etc. is used. In the drawings, the thickness of the self-adhesive layer 14 is emphasized.

(Summary of tie)
The binder V of the embodiment described below is for bundling a plurality of wires H. The binding tool V is configured by combining two sheets 10, 10 having a self-adhesive layer 14 provided on only one surface of the base material 12 on the entire surface, and bonding only between the self-adhesive layers 14, 14. ing. Here, one of the two sheets 10 and 10 is referred to as a first sheet 10A, and the reference numeral of the constituent element of the first sheet 10A is attached with “A”, and the other of the two sheets 10 and 10 is In some cases, the two sheets 10B may be distinguished by adding "B" to the reference numerals of the constituent elements of the second sheet 10B. The layer configuration of the first sheet 10A and the second sheet 10B may be the same or different. For example, as described later, the protective layer 13a of the second sheet 10B disposed on the inner side of the first sheet 10A. It is possible to change as appropriate, such as omitting.

  For example, as shown in FIGS. 2, 6 and 13, the binding tool V includes a first sheet 10A having a first self-adhesive layer 14A provided on the entire surface of the first base 12A only, and a first sheet 10A. And a second sheet 10B having a second self-adhesive layer 14B provided on the entire surface only on one surface of the second substrate 12B. The binding tool V is bonded by the first self-adhesive layer 14A at one edge of the first sheet 10A and the second self-adhesive layer 14B at one edge of the second sheet 10B, and the other edge in the first sheet 10A. Of the first self-adhesive layer 14A and the second self-adhesive layer 14B of the other edge of the second sheet 10B. Then, in the binding tool V, the first sheet 10A and the second sheet 10B are annularly connected. Further, in the first sheet 10A, the first sheet 10A is disposed with the first self-adhesive layer 14A facing inward such that the first self-adhesive layer 14A is in contact with the wiring H. Furthermore, the second sheet 10B with the second self-adhesive layer 14B facing outward is disposed more inside than the first sheet 10A.

  According to the binding device V, the plurality of wires H can be appropriately bundled with a simple configuration in which the first sheet 10A and the second sheet 10B are combined. Since the first sheet 10A is disposed with the first self-adhesive layer 14A facing inward, the binding tool V does not have to cover the first sheet 10A with the second sheet 10B. The two sheets 10B can be set with a minimum size sufficient to connect the edges of the first sheet 10A. That is, since the relatively small second sheet 10B may be used, the cost of the binder V can be suppressed. And since the binding tool V is fundamentally comprised by the base material 12 outside, it can not be easily damaged and can exhibit characteristics, such as abrasion resistance derived from the protective layer 13a of the base material 12, and slidability. . Moreover, since the binding tool V has a configuration in which the first self-adhesive layer 14A is in contact with the held wire H, the frictional resistance of the first adhesive layer 14A higher than the base 12 can make the wire H difficult to shift. . As described above, since the binding tool V does not easily shift the wiring H, even if the wire harness W vibrates while the vehicle is traveling, the occurrence of abnormal noise due to the sliding between the binding tool V and the wiring H can be prevented. .

  Since the binding tool V can reduce the overlapping portion of the first sheet 10A and the second sheet 10B, the external dimensions of the holding portion 16 for bundling the wiring H can be reduced, and the flexibility not to prevent bending of the bundled wiring H The degree of freedom according to the specifications required of the wire harness W, such as securing, is high, and convenience can be improved. In addition, the binding tool V is a so-called “of” character-wound bundling form (the first bundling form, FIG. 2) and the holding portion 16 where the pierced and stuck hook portion 18 holds the wiring H depending on the winding method. Selecting an extending binding form (second binding form, for example, FIG. 4, FIG. 7 and FIG. 8) and a binding form having both the first binding form and the second binding form (FIG. 13) Yes, it is excellent in convenience.

(Outline of wire harness)
For example, as shown in FIG. 1, a plurality of wires H are bundled by the binding tool V at appropriate locations such as straight portions, branch portions where the directions of the wires H are divided, and the vicinity of the branch portions. Configured In addition, the wire harness W may be bundled by not only the aspect bundled with the several binding tool V but by one binding tool V. FIG. Since the wire harness W uses the convenient binding tool V at a low cost, the convenience can be improved while suppressing the cost.

First Embodiment
As shown in FIG. 2, in the binding device V1 according to the first embodiment, the entire first sheet 10A is disposed so as to be wound around a plurality of wires H, and the first self-adhesive layer 14A facing inward is a wire It is supposed to touch H. In addition, the second sheet 10B bonds the second self-adhesive layer 14B of itself to the first self-adhesive layer 14A of the first sheet 10A, and connects the edges of the first sheet 10A wound around a plurality of wires H. It is arranged as. The first sheet 10A is set to have substantially the same dimensions as the circumference of the plurality of wires H to be bundled. When the size is set equal to or smaller than the circumferential dimensions of the plurality of wires H, the edge portions of the first sheet 10A do not overlap when wound around the plurality of wires H, and the wire harness W Even if it vibrates, the generation of abnormal noise due to the sliding can be prevented. In addition, in most of the area around the circumference of the plurality of wires H, only the first sheet 10A (single layer) is wound, so it has excellent flexibility and is easily bent. When the first sheet 10A is set large relative to the circumferential dimensions of the plurality of wires H, the remaining portion of the first sheet 10A is cut after winding, or the first self-adhesive layer 14A of the first sheet 10A By bonding between each other, it is possible to reduce or prevent the generation of abnormal noise. In addition, if the first sheet 10A is set large relative to the circumferential dimensions of the plurality of wires H, the other edge of the first sheet 10A and the other edge of the second sheet 10B can be easily aligned, and the work of assembly is performed. It is possible to improve the quality. In the second sheet 10B, the dimension between the one edge and the other edge is set smaller than the dimension between the one edge and the other edge in the first sheet 10A. When the binding tool V1 connects the first sheet 10A with the second sheet 10B in a state where the first sheet 10A is wound around the wiring H and the opposing edges abut each other, the second self-adhesive layer 14B facing outward is the first It is preferable because it is covered by the sheet 10A. In the first sheet 10A, the binding tool V1 may be wound around the wire H and a gap may be provided between the opposing edges, or may be overlapped. The binding device V1 has a plurality of wires in a so-called “no” character-wound binding form (first binding form) that does not have the hook portion 18 extending like a flange from the holding portion 16 surrounding the plurality of wires H H is configured to be bundled, and the binding tool V1 has flexibility to be easily bent in the extending direction of the wiring H.

  Next, the manufacturing method of the wire harness W using the binding tool V1 of 1st Embodiment is demonstrated with reference to FIG. The one edge portion of the first sheet 10A and the one edge portion of the second sheet 10B are disposed such that the self-adhesive layers 14A and 14B overlap each other (FIG. 3 (a)). A bonded sheet obtained by bonding 14B is obtained (FIG. 3 (b)). At this time, the other edge of the second sheet 10B extends outside the one edge of the first sheet 10A. The first sheet 10A is wound around the plurality of wires H such that the first self-adhesive layer 14A of the first sheet 10A is on the inside and the second self-adhesive layer 14B of the second sheet 10B is on the outside See Figure 3 (c) and (d)). After arranging one edge of the first sheet 10A to which the second sheet 10B is joined along the outer periphery of the wiring H, the other edge opposite to the edge to which the second sheet 10B of the first sheet 10A is joined The portion is superimposed on the second self-adhesive layer 14B of the second sheet 10B extending outward from the first sheet 10A and facing outward (FIG. 3 (e)). As a result, the first self-adhesive layer 14A facing inward at the other edge of the first sheet 10A and the second self-adhesive layer 14B of the second sheet 10B overlap and adhere to each other (see FIG. 2), A wire harness W in which a plurality of wires H are bundled by the binding tool V1 is obtained.

  According to the binding device V1 of the first embodiment, the following effects are produced in addition to the effects described above. The binding tool V1 does not have a configuration in which the heel portion 18 in which the sheets 10 are bonded together in a form of a palm is formed, but a binding form of so-called "no" character winding. In addition, most of the portion holding the wiring H in the binding device V1 is a single sheet of only the first sheet 10A. As a result, the binding tool V1 has a flexibility capable of bending and deforming itself to some extent, and it is possible to prevent the deformation of the wiring H from being hindered by the presence of the binding tool V1. Therefore, the assembly | attachment workability | operativity of the wire harness W which has the binding tool V1 can be improved. Such a binding tool V1 is suitable, for example, for temporarily fixing the wiring H. The binding tool V1 sets the width of the second sheet 10B to be smaller than the width of the first sheet 10A, thereby reducing the overlapping range of the first sheet 10A and the second sheet 10B. Thereby, the binding tool V1 can be easily deformed in the direction intersecting with the extending direction of the wiring H. Moreover, by setting the second sheet 10B to a narrow width, the binding tool V1 can suppress the thickness of the binding tool V1 and make the wire harness W compact.

  Since the binder V1 directs the first self-adhesive layer 14A of the first sheet 10A to the inner side, when bonding the first sheet 10A wound around the wiring H to the second sheet 10B, the first self-adhesive layer 14A Can be avoided from being accidentally joined. In addition, the binding tool V1 sets the first self-adhesive layer 14A at the other edge of the first sheet 10A to the second one of the second sheet 10B based on the one edge of the first sheet 10A to which the second sheet 10B is stuck. When the first sheet 10A is attached to the self-adhesive layer 14B, it is possible to prevent positional deviation such as when the first sheet 10A is inclined, and to bundle the wires H appropriately and bundle them. Then, the binding tool V1 can be obtained by a simple procedure of combining the first sheet 10A and the second sheet 10B of the same layer configuration and winding them around the wiring H, and for the production of the wire harness W, to improve the workability. It can contribute.

The ridge portion 18 is formed by overlapping the portions extending from the annularly formed holding portion 16 surrounding the plurality of wires H in the first sheet 10, and bonding the first self-adhesive layers 14A and 14A to each other. Ru. Further, in the binding tool V2, the second sheet 10B is arranged so as to connect the edge portions of the first sheet 10A. The binding tool V2 is set to be larger than the circumferential dimensions of the plurality of wires H to be bundled by the first sheet 10A, and when being wound around the plurality of wires H, the first sheet 10A is overlapped in a spiral shape. Can be surplus. As described above, the binding tool V2 is configured to bundle the plurality of wires H in a binding form (second binding form) having the hook portion 18 extending like a flange from the holding portion 16 surrounding the plurality of wires H, Due to the hook portion 18, the binding tool V2 has rigidity that is difficult to bend in the extending direction of the wiring H.

  The binder V2 of the second embodiment will be more specifically described. As shown in FIGS. 4 and 5, the first sheet 10A extends from the holding portion 16 and has one edge portion folded from the holding portion 16 so that the edges of the first self-adhesive layer 14A and 14A face each other. The ridge portion 18 is formed by the other edge which extends and the first self-adhesive layer 14A is disposed so as to face the first self-adhesive layer 14A of the one edge. The holding portion 16 is formed so that the first self-adhesive layer 14A is on the inner side, and the first self-adhesive layer 14A is in contact with the wiring H being held. In addition, the second sheet 10B bonds the second self-adhesive layer 14B to the first self-adhesive layer 14A of the edge folded back at one edge of the first sheet 10A, and The second self-adhesive layer 14B is attached to the first self-adhesive layer 14A, and the second self-adhesive layer 14B is disposed in the ridge portion 18 so as to connect the edges of the first sheet 10A disposed in the ridge portion 18. And in the binding tool V2, the junction part which 1st self-adhesive layers 14A and 14A which face each other in the heel part 18 stick on both sides which sandwich the 2nd sheet 10B is formed.

One edge portion of the first sheet 10A and one edge portion of the second sheet 10B are disposed such that the self-adhesive layers 14A and 14B overlap each other, and the self-adhesive layers 14A and 14B are bonded and joined to each other A bonding sheet is obtained (FIG. 6 (a)). At this time, the other edge of the second sheet 10B extends outside the one edge of the first sheet 10A. The holding portion 16 is formed by winding the first sheet 10A so as to sandwich the plurality of wires H such that the first self-adhesive layer 14A is on the inner side (FIG. 6 (b)). The second self-adhesive layer of the second sheet 10B which is joined to one edge by folding back the edge of the other edge out of the edges extending from the holding portion 16 in the first sheet 10A and facing each other in a convoluted manner The first self-adhesive layer 14A is attached to 14B (FIG. 6 (c)). Further, in the first sheet 10A, one edge portion and the other edge portion facing each other in the combined shape are pasted together by the first self-adhesive layers 14A and 14A, and the edge of the folded other edge portion is the first self-adhesive layer 14A, 14A. Paste together. Thereby, the wire harness W in which the plurality of wires H are bundled is obtained by the binding tool V2 that holds the plurality of wires H by the holding portion 16 formed of the first sheet 10A and has the hook portion 18 extending from the holding portion 16 Be

In addition, in the reference example 2, although the holding piece 32 described in the reference example 1 is provided, even if the holding piece 32 is omitted, the holding piece 32 is replaced with the insertion portion 42 or the embodiment is described. The binding tool V may be combined. Further, the insertion portion 42 is not limited to the linear cut, and may be L-shaped, V-shaped, X-shaped, H-shaped, U-shaped, circular, etc. The insertion portion 42 may be formed by a through hole that is open such as a hole.

  Next, a method of manufacturing the wire harness Y using the binder S2 of the reference example 2 will be described with reference to FIGS. 23 and 24. In accordance with the extending position of the wiring H, a cut that penetrates in the thickness direction is formed in the sheet 10, and the insertion portion 42 is provided (FIG. 23A). The wiring H is disposed on the side of the self-adhesive layer 14 of the sheet 10 (FIG. 23 (b)). Pass one of the branched wires H through the insertion portion 42 and bend the holding piece 32 across the wire H with the side connected to the sheet body 10a as the root, the self-adhesive layer 14 at the tip of the holding piece 32 is the sheet body 10a The tip of the holding piece 32 wound around the wire H is pressed to the adhesive layer 14 and joined to the sheet main body 10a (FIGS. 23 (c) and 24 (a)). A half of the sheet body 10a is bent along the wiring H, superimposed in the shape of a straddle so as to straddle the wiring H, and bonding the self-adhesive layers 14 facing each other (FIGS. 23 (d) and 24 (b) ). As a result, the wire H is passed through the insertion portion 42 and the wire harness Y in which the branched portion of the wiring H is held is obtained by the binding tool S2 in which the branched portion of the wiring H is sandwiched by the sheet main body 10a.

  According to the binding tool S2 of the reference example 2, not only can a plurality of wires H be appropriately bundled with a simple configuration including one sheet 10, but the wires H can be held by being sandwiched by the sheet main body 10a. it can. Further, since the insertion portion 42 is provided integrally with the sheet 10, by holding the wiring H by the insertion portion 42, the sheet 10 and the wiring H can be positioned, and the binding tool S2 can be wired H Can be placed at an appropriate position. By using the binding tool S2, it is not necessary to temporarily fasten the plurality of wires H with a vinyl tape or the like different from the binding tool S2, and the number of parts relating to the wire harness Y, the number of operation steps, and the like can be reduced. The binding tool S2 is disposed such that the sheet body 10a and the self-adhesive layer 14 of the holding piece 32 face inward. Accordingly, since the outer side of the binding tool S2 is basically formed of the base material 12, the binding tool S2 is hard to be damaged and can exhibit characteristics such as abrasion resistance and slidability derived from the protective layer 13a of the base material 12. . In addition, when the self-adhesive layer 14 faces outward, there is a possibility that it may be unintentionally joined to the other sheet 10 at the time of winding work of the other binder S2, etc., but the binder S2 is a self-adhesive As the layer 14 does not go outside, the problems mentioned above can be avoided. Then, the binding tool S2 can be obtained by a simple procedure in which the sheet body 10a is folded back after passing the wiring H through the insertion portion 42, and the manufacturing of the wire harness Y can contribute to the improvement of the workability.

For example, the present invention can be modified as follows.
(1) The shape of the cut constituting the holding piece, the insertion portion and the like may be formed in an appropriate opening shape such as a linear cut obtained by cutting the sheet or a gap having a width.
(2) The layer structure of the substrate is not limited to the above-described configuration.
(3) The wire harness may be configured by combining the embodiment and the reference example described above.

  Conventionally, when producing a wire harness, a plurality of wires may be temporarily fixed in advance by another material such as a vinyl tape before bundling the plurality of wires with a binding tool, and also in the case where the wires branch. It is practiced to temporarily fix and branch off the branched wiring with another material such as. For this reason, when manufacturing a wire harness, it is necessary to use a plurality of materials, and there is a problem that workability is bad. As the invention which can solve such a problem, the present disclosure includes the following. According to the invention described below, since the binding tool itself can be temporarily fixed, it is not necessary to temporarily fix it with a separate material from the binding tool, and it is possible to reduce the number of parts regarding the wire harness, the operation man-hour, and the like.
