Description

  The present invention relates to an electric wire fixing structure for fixing an electric wire to a protector.

  Various wire fixing structures for the protector have been conventionally proposed (see Patent Documents 1 and 2). One conventional example of a wire fixing structure to a protector is shown in FIGS. 8 (a) and 8 (b). This electric wire fixing structure has a protector 50. The protector 50 includes a bottom wall 51 and a pair of side walls 52 erected from both ends of the bottom wall 51, and an electric wire housing space 53 is formed surrounded by these. Extending bottom wall portions 51 a that protrude outward from both ends of the pair of side walls 52 and protrude from the bottom wall 51 are provided on both ends in the longitudinal direction of the protector 50. The electric wire W is fixed to the protector 50 by arranging the electric wire W in the electric wire housing space 53 and fastening the electric wire W together with the extended bottom wall portion 51 a by the binding band 60.

  However, the electric wire W arranged in the electric wire housing space 53 may be thick or may be thin as a whole electric wire diameter size (in the case of plural wires, the entire size in a state where a plurality of electric wires are bundled). When the wire diameter is large, the wire W can be fixed in the binding band 60 without a gap. However, when the wire diameter size is small, as shown in FIG. 8B, the wire is fastened with a gap d in the binding band 60 and cannot be reliably fixed. Here, when the protector 50 is manufactured in accordance with the case where the overall wire diameter size is thin, the wire W having a large wire diameter size cannot be accommodated in the protector 50 and protrudes to the outside. If the electric wire W protrudes outside from the protector 50, the original function as the protector 50 of protecting the electric wire W cannot be performed.

  Here, in the electric wire fixing structure disclosed in Patent Document 1, when the electric wire diameter size is small with respect to the size of the electric wire accommodating space, a gap is generated in the binding band, as in the conventional example, and is firmly It cannot be fixed to.

  In the electric wire fixing structure disclosed in Patent Document 2, since the binding band is disposed in the electric wire housing space, an electric wire having a small electric wire diameter can be reliably fixed. However, in the case of a wire with a large wire diameter, if the wire is restrained directly with a binding band, the binding band receives a strong reaction force from the wire in a small area, and the binding band cannot be fixed securely. There is a fear.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a wire fixing structure that can securely fix an electric wire regardless of the electric wire diameter size without changing the size of the protector. And

  According to the present invention, there is provided an electric wire housing space surrounded by a bottom wall and a pair of side walls erected from both ends in the width direction of the bottom wall, and a part of each side wall from both sides in the width direction of the bottom wall. A protector having a pair of band insertion holes that are open to the inside, an inner peripheral band path that passes through the pair of band insertion holes from the outside of the bottom wall and enters the wire housing space, and from the outside of the bottom wall A binding band that can be selectively routed to an outer peripheral band path that passes through the pair of band insertion holes and wraps around the outside of the pair of side walls, and the binding band includes the inner peripheral band path and the outer peripheral band path. The electric wire fixing structure is characterized in that the electric wire arranged in the electric wire receiving space is fixed to the protector.

  According to the present invention, when the wire diameter size is thin, the binding band is fixed to the protector on the inner band route through the inner band route, and when the wire diameter size is thick, the binding band is connected through the outer band route. The electric wire in the electric wire housing space is fixed to the protector. In the inner band path, since the width of the pair of band insertion holes is smaller than the width of the pair of side walls, the electric wire can be fastened in the binding band without any gap, so that the electric wire can be fixed securely. In the outer peripheral band route, the electric wire is fastened together with the pair of side walls in a state where the electric wires are arranged inside the pair of side walls by the binding band, so that the reaction force from the electric wire having a large electric wire diameter acts on the electric wires only through the pair of side walls. Therefore, the electric wire can be securely fixed. As mentioned above, even if it does not change the size of a protector, an electric wire can be fixed reliably irrespective of an electric wire diameter size.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
1 to 3 show a first embodiment of the present invention. The electric wire fixing structure according to the first embodiment includes a protector 1A and a binding band 10.

  The protector 1 </ b> A includes a bottom wall 2, a pair of side walls 3 erected from both ends in the width direction of the bottom wall 2, and a vehicle body mounting bracket portion 4 projecting from the bottom wall 2 side of one side wall 3. And. An electric wire housing space 5 is formed surrounded by the bottom wall 2 and the pair of side walls 3. The electric wire housing space 5 is opened on the upper side. The electric wire W is accommodated in the electric wire accommodating space 5 from this opening. A pair of band insertion holes 6, a pair of band cutouts 7, and a pair of band holding portions 8 are respectively provided at both ends of the protector 1 </ b> A in the direction of wiring.

  The pair of band insertion holes 6 are opened from both sides in the width direction of the bottom wall 2 to a part of each side wall 3. As the distance L1 between the inner peripheral ends of the pair of band insertion holes 6 is smaller, the wire W having a smaller overall wire diameter size can be fastened without a gap, but the minimum necessary strength as the protector 1A can be secured. It is a dimension.

  The pair of band cutout portions 7 are formed by being cut out in a rectangular shape downward from the upper ends of the pair of side walls 3. The depth L21 of the band cutout 7 is such that the deeper the wire W, the smaller the overall wire diameter size, can be fastened without gaps, but the minimum required strength as the protector 1A can be secured. .

  The pair of band holding portions 8 are provided so as to protrude outside the side wall portions 3. Each band holding portion 8 is formed with a through hole 8a for the binding band 10 in the vertical direction.

  The binding band 10 is a band-shaped member and is formed so that it can be bound at a desired position. As shown in FIGS. 2 (a) to 2 (c), the binding band 10 includes an inner peripheral band path that enters the internal wire housing space 5 from the outside of the bottom wall 2 through the pair of band insertion holes 6, and FIG. As shown in (a) to (c), from the inside of the bottom wall 2 through the pair of band insertion holes 6 to the outside of the pair of side walls 3 and to the outer peripheral band path through which the pair of band holding portions 8 pass. It can be selectively arranged.

  Next, the fixing work of the electric wires (whether a plurality of electric wire bundles or one wire W) will be described. Hereinafter, for convenience of explanation, the wire diameter size as a whole (in the case of a plurality of wires, the overall size in a state where a plurality of wires are bundled, the same applies hereinafter) is a thin wire W1, and a wire having a large wire diameter size is W2. To do. When the electric wire W1 having a small electric wire diameter is fixed, the binding band 10 is used as the inner peripheral band path shown in FIGS. 2A to 2C, and the electric wire W1 arranged in the electric wire accommodating space 5 is fastened by the binding band 10. To do. In the inner band path, since the width L1 of the pair of band insertion holes 6 is smaller than the width of the pair of side walls 3, the electric wire W1 can be fastened in the binding band 10 without a gap, so that the electric wire W1 can be fixed securely.

  When the electric wire W2 having a large electric wire diameter is fixed, the binding band 10 is used as the outer peripheral band path shown in FIGS. 3A to 3C, and the binding band 10 is passed through the pair of band cutout portions 7 so as to connect the electric wire W2. Are fastened with a binding band 10. In the outer peripheral band path, the electric wire W2 is fastened together with the pair of side walls 3 in a state where the electric wire W2 is disposed inside the pair of side walls 3 in the binding band 10, and thus the reaction force from the electric wire having a large electric wire diameter is generated by the pair of side walls 3 It acts on the electric wire W2 only through, and the electric wire W2 can be reliably fixed. As described above, even if the size of the protector 1A is not changed, the electric wires W1, W2 can be reliably fixed regardless of the electric wire diameter size.

  The pair of side wall portions 3 are provided with a pair of band cutout portions 7. Since the binding band 10 is passed through the pair of band notches 7, the positional displacement of the binding band 10 together with the pair of band insertion holes 6 is reliably prevented, so that the electric wire W <b> 2 can be more reliably fixed.

  A band holding portion 8 is provided on the pair of side wall portions 3. Therefore, since the binding band 10 before fastening can be held at a position where fastening is easy, the workability of fastening the electric wire W is improved.

  The pair of band insertion holes 6 are provided at both ends of the protector 1A in the wire routing direction. Therefore, since the electric wire W is fastened by the binding band 10 at both ends in the length direction of the protector 1A, it is not necessary to wind the tape at both ends of the protector 1A. That is, the binding band 10 also serves as a tape winding function. As a result, the tape winding operation can be omitted, so that the workability is improved and the tape winding portion does not have to be set at both ends of the protector 1A, so that the protector 1A can be reduced in size and cost.

  In addition, as an outer periphery band path | route, the path | route which goes around the outer side of a pair of side wall 3 via a pair of band penetration hole 6 from the outer side instead of the inner side of the bottom wall 2, and lets a pair of band holding part 8 pass is also considered.
