Description

  This invention relates to a technique for holding an electric wire in a fixed position when assembling a wire harness for an automobile, for example.

  Assembly of wire harnesses for automobiles and the like is performed as follows. That is, a wire harness routing path in a vehicle is expressed as a harness assembly path on an assembly drawing board or an assembly frame, and an electric wire holder is provided at an appropriate position along the harness assembly path. And a some electric wire is hold | maintained with an electric wire holder, and is arrange | positioned along a harness assembly path | route. In this state, each electric wire is bundled using a binding tool such as a tape, or a connector is attached to the end of the electric wire. Thereby, a wire harness is assembled.

  As an electric wire holder used in the assembly of the wire harness, there is one having a holding portion formed in a substantially U shape. In such an electric wire holder, if a plurality of electric wire terminals with connectors are arranged in a substantially U-shaped portion of the holding part, the electric wire terminals are supported in a mounting manner so that the connector is hooked on the holding part. Can be routed while. For this reason, it is excellent at the point which hold | maintains the several electric wire terminal with a connector in a predetermined position. Further, since a relatively large number of electric wires can be inserted and arranged in the substantially U-shaped portion, it is also excellent in that a relatively large number of electric wires are held.

  However, in the electric wire holder as described above, with respect to the electric wire terminal to which the connector is not attached, even if the electric wire terminal is routed in the substantially U-shaped part of the holding part, it cannot be expected to be caught in the holding part. Therefore, there is a problem that the cable cannot be routed while being held in the substantially U-shaped portion of the holding portion.

  Therefore, as disclosed in Patent Document 1, a support has been proposed in which a rubber plate provided with a cut is held so as to be sandwiched between substantially U-shaped frame portions. This support is excellent in that the electric wire is supported by being inserted by a notch of a rubber plate, and thus the electric wire terminal to which no connector is attached is firmly positioned and held.

Japanese Patent Laid-Open No. 08-17270

  However, since the support disclosed in Patent Document 1 is a dedicated product suitable for holding an electric wire terminal to which no connector is attached, what is an electric wire holder having a holding portion formed in a substantially U shape? It needs to be prepared as a completely different one. That is, when assembling the wire harness, an electric wire holder having a holding portion formed in a substantially U-shape and a support tool as disclosed in Patent Document 1 are separately prepared, and these are distinguished from each other and a harness assembly path It is necessary to arrange along. For this reason, the assembly complexity of the wire harness assembly tool, the cost increase, etc. were invited.

  Accordingly, an object of the present invention is to obtain a wire holder for firmly positioning and holding an electric wire to which a connector is not attached, relatively easily and at low cost.

  An electric wire holder according to the present invention is an electric wire holder for holding an electric wire, and includes an electric base having a base portion and a pair of rod-like portions protruding from the base portion so as to extend in parallel with a gap therebetween. A receiving portion and a plurality of insertion holes that are formed in a plate shape wider than the width dimension of the pair of rod-shaped portions and into which the rod-shaped portions can be inserted along each linear portion corresponding to the pair of rod-shaped portions. An elastic sheet member provided with an insertion hole row and a cut portion formed between the insertion hole rows, so that the pair of rod-like portions are inserted into the insertion holes of the corresponding insertion hole row. Thus, the elastic sheet member is attached to the wire receiving portion.

  In this case, the outer side edge part of the said notch part may have the electric wire insertion guide part which expands sequentially toward outward.

  Further, at least one of the pair of rod-shaped portions is formed in a non-circular cross-sectional shape, and at least one of the insertion holes into which the rod-shaped portions having a non-circular cross-sectional shape are inserted has a non-circular hole shape. It may be formed.

  An elastic sheet member for an electric wire holder according to the present invention is formed in a plate-like member having elasticity, provided with an insertion hole array having a plurality of insertion holes along a pair of linear portions, A cut portion is formed between the hole rows.

  According to the electric wire holder of the present invention, with respect to the electric wire receiving part itself having a base and a pair of bar-like parts protruding from the base so as to extend in parallel with a gap, the electric wire is connected between the pair of bar-like parts. Since the electric wire can be held by being placed on the base and placed on the base, the electric wire terminal to which the connector is attached is held at a predetermined position, and it is suitable for holding a relatively large number of electric wires. For example, when holding an electric wire to which a connector is not attached, the elastic sheet member is inserted into the electric wire receiving portion by inserting a pair of rod-like portions into the respective insertion holes of the corresponding insertion hole row. Install to. Thereby, the electric wire to which no connector is attached can be held so as to be sandwiched between the cut portions. For this reason, the electric wire holder for firmly positioning and holding the electric wire to which the connector is not attached can be obtained relatively simply and at low cost using the electric wire receiving portion as described above.

  Further, when the outer end portion of the cut portion has a wire insertion guide portion that sequentially expands outward, the wire can be easily inserted into the cut portion via the wire insertion guide portion. .

  Further, at least one of the pair of rod-shaped portions is formed in a non-circular cross-sectional shape, and at least one of the insertion holes into which the rod-shaped portions having a non-circular cross-sectional shape are inserted has a non-circular hole shape. If formed, rotation of the insertion hole with respect to the rod-shaped portion having a non-circular cross-sectional shape is suppressed, and the posture change of the elastic sheet member with respect to the wire receiving portion can be suppressed.

  Further, according to the elastic sheet member for the electric wire holder of the present invention, an insertion hole row having a plurality of insertion holes is provided along a pair of linear portions, and each insertion is formed. Since the cut portion is formed between the hole rows, the elastic sheet member can be attached to the wire receiving portion so that the pair of rod-like portions of the wire receiving portion pierce each insertion hole of the insertion hole row. . And it can hold | maintain so that an electric wire may be pinched | interposed in a notch part. For this reason, the electric wire holder for firmly positioning and holding the electric wire to which the connector is not attached can be obtained relatively simply and at low cost by using the pair of rod-like portions of the electric wire receiving portion.

  Hereinafter, the electric wire holder which concerns on embodiment of this invention is demonstrated. FIG. 1 is an exploded perspective view showing an electric wire holder, and FIG. 2 is a perspective view showing a state in which the electric wire is held by the electric wire holder.

  The electric wire holder 10 is for holding the electric wire 50 along the assembly path of the harness when assembling a wire harness of an automobile or the like.

  The electric wire holder 10 includes an electric wire holding main body 12 and an elastic sheet member 20.

  The electric wire holding main body portion 12 includes an electric wire receiving portion 14 that holds the electric wire 50 and a fixing portion 18 that is fixed to an assembly drawing board or an assembly frame.

  The wire receiving portion 14 is a member formed by bending a metal round bar or the like having a substantially circular cross section into a substantially U shape, a substantially arc-shaped base portion 15 at the bottom portion of the substantially U shape, and both ends of the base portion 15. And a pair of rod-like parts 16 projecting upward from the part. The pair of rod-like portions 16 are provided so as to extend in parallel with an interval. The distance between the pair of rod-like parts 16 is preferably substantially the same as or larger than the diameter of the thick part of the wire harness to be assembled. The pair of rod-like parts 16 have substantially the same length dimension, and each tip part is formed in a substantially semispherical shape.

  Further, a fixing portion 18 is formed so as to protrude from a substantially central portion of the base portion 15 of the wire receiving portion 14 in a direction opposite to the extending direction of the pair of rod-like portions 16. The fixing portion 18 is formed in a bolt shape having a thread groove formed on the outer periphery. The electric wire holder 10 is fixed to the assembly drawing plate or the assembly frame by screwing the fixing portion 18 to the nut member on the assembly drawing plate or the assembly frame side. A nut 19 is screwed to the fixing portion 18, and the fixing portion 18 is screwed to a nut member on the assembly drawing plate or the assembly frame side by adjusting the screwing amount of the nut 19 to the fixing portion 18. The screwing amount at the time, that is, the fixed height of the electric wire holder 10 is set and adjusted.

  The electric wire holding main body 12 configured in this way is fixed to an assembly drawing board or an assembly frame alone. When the electric wire holding main body 12 is used alone, it is usually attached to a position for holding the terminal portion of the electric wire with connector and the middle portion of the route in the assembly route of the wire harness.

  In addition, in this embodiment, although the base 15 demonstrated in the example which is a substantially arc shape, it is not restricted to such an example. For example, the base portion may be formed in a linear member, and a pair of rod-like portions 16 may be extended from an end portion or an intermediate portion thereof at a substantially right angle to the base portion.

  The elastic sheet member 20 is a member formed of an elastic plate member such as a rubber plate. The elastic sheet member 20 is formed as a substantially square plate-like member having a width dimension W2 larger than the width dimension W1 of the pair of rod-like portions 16. Insertion hole rows 22 and 24 are provided along the straight portions L1 and L2 corresponding to the pair of rod-like portions 16. Each insertion hole row 22, 24 has a plurality of (here, two) insertion holes 22 h, 24 h formed at intervals along the linear portions L 1, L 2.

  The insertion holes 22h and 24h are formed in a shape and size into which the rod-like portion 16 can be inserted. Here, the insertion holes 22h and 24h are formed in a substantially circular hole shape. The diameters of the insertion holes 22h and 24h may be substantially the same as, or larger than, the diameter of the rod-like portion 16. However, when the electric wire 50 is inserted into the cut portion 26 with the elastic sheet member 20 attached to the electric wire receiving portion 14 as described later, the insertion holes 22h and 24h portions of the elastic sheet member 20 are fixed to the rod-like portion 16. It is preferable that a frictional force capable of being held in position is acting between the rod-shaped portion 16 and the insertion holes 22h and 24h. For this purpose, the diameters of the insertion holes 22 h and 24 h are preferably smaller than the diameter of the rod-shaped portion 16.

  Further, the elastic sheet member 20 has a cut portion 26 formed therein. The notch portion 26 is between the insertion hole rows 22 and 24 and is located on the other side from one side (upper side) substantially orthogonal to the linear portions L1 and L2 among the sides of the elastic sheet member 20. It is formed in a cut shape that reaches the middle of the side (lower side). Further, the outer end portion (the end portion on the upper side) of the cut portion 26 is sequentially expanded outward, more specifically, in the electric wire insertion guide portion 26g that expands in a substantially V shape. Is formed. Such a cut | notch part 26 is formed by cut | disconnecting the elastic sheet member 20 using the blade of a cutter, scissors, etc., for example.

  The elastic sheet member 20 configured as described above is attached to the wire receiving portion 14 as follows. That is, the pair of rod-like portions 16 are pierced through the respective insertion holes 22h and 24h of the corresponding insertion hole rows 22 and 24. More specifically, each rod-like portion 16 is placed on one of the insertion holes 22h and 24h of the corresponding insertion hole row 22 and 24 on the side opposite to the opening of the notch 26, and Insert from the direction side toward the other side. Then, the insertion holes 22 h and 24 h in which the rod-like portion 16 has been inserted in the elastic sheet member 20 are moved to the proximal end side of each rod-like portion 16. Further, before and after this, each rod-like portion 16 is inserted into each of the insertion holes 22h, 24h of the corresponding insertion hole row 22, 24, and each insertion hole 22h positioned next to each inserted insertion hole 22h, 24h, 24h is inserted from the other surface side of the elastic sheet member 20 toward the one surface side. In addition, when there are three or more insertion holes 22h and 24h corresponding to each rod-shaped portion 16, the above is repeated and each rod-shaped portion 16 is inserted into each corresponding insertion hole 22h and 24h. Thereby, the elastic sheet member 20 is attached to the wire receiving portion 14.

  The electric wire holder 10 thus configured is fixed to an assembly drawing board or an assembly frame. The electric wire holder 10 to which the elastic sheet member 20 is attached is usually provided at a portion of the assembly path of the wire harness that fixes the end portion of the wire harness, particularly the end of the electric wire 50 to which no connector is attached. It is done. The elastic sheet member 20 may be attached after the wire holding main body 12 is fixed to the assembly drawing board or the assembly frame.

  And in holding the electric wire 50, the electric wire 50 is inserted in the notch part 26, elastically deforming it via the electric wire insertion guide part 26g. At this time, since the electric wire insertion guide part 26g is formed in a shape that sequentially expands outward, the electric wire 50 can be easily inserted into the notch part 26 while pressing against the electric wire insertion guide part 26g. Further, the electric wire 50 inserted into the cut portion 26 is held relatively firmly so as to be pinched by the elastic restoring force of the cut portion 26.

  At this time, the terminal portion of the electric wire 50 is disposed on the side of the elastic sheet member 20 that is curved so as to be recessed, and the portion from the middle of the electric wire 50 is curved so that the elastic sheet member 20 protrudes. It is preferable to be arranged. In other words, when the electric wire holder 10 is fixed to the assembly drawing board or the assembly frame, the posture of the elastic sheet member 20 that is curved so as to be recessed faces the side where the electric wire terminal portion is disposed in the assembly path. It is preferable that

  The reason why this is preferable is as follows.

  That is, when the electric wire 50 is pulled out from the cut portion 26, since a terminal or the like is attached to the electric wire terminal portion, it is necessary to pull out the electric wire so as not to damage the terminal. For this reason, normally, the electric wire 50 is pulled out with a portion from the middle of the electric wire holder 10. In addition, in order not to damage the terminals and the like of the electric wire terminal portion, it is preferable to pull out toward the upper side of the cut portion 26 while holding the portion of the electric wire 50 near the electric wire holder 10.

  Here, in this electric wire holder 10, since the rod-shaped part 16 exists in the side curving so that it may become dented among the elastic sheet members 20, the part near the electric wire holder 10 among the electric wires 50 is provided. It is difficult to have Therefore, by arranging the portion from the middle of the electric wire 50 on the side of the elastic sheet member 20 so as to protrude so as to protrude, the portion of the electric wire 50 that is intermediate from the electric wire holder 10 is formed. Thus, it becomes easy to grab a part immediately adjacent to the electric wire holder 10 and lift it upward.

  According to the electric wire holder 10 configured as described above, the electric wire receiving portion 14 itself having the base portion 15 and the pair of rod-like portions 16 protruding from the base portion 15 so as to extend in parallel with a gap therebetween. Since, like the conventional substantially U-shaped jig, the electric wire 50 with a connector or a plurality of electric wires can be held between the pair of rod-like portions 16 and placed on the base portion 15, It is suitable for holding the connector-attached electric wire 50 and a relatively large number of electric wires in a predetermined position. Then, the elastic sheet member 20 is attached to the wire receiving portion 14 so that the pair of rod-like portions 16 are inserted into the insertion holes 22h and 24h of the corresponding insertion hole rows 22 and 24, thereby being attached to the connector. It is possible to hold the electric wire 50 that is not sandwiched between the cut portions 26. For this reason, the electric wire holder 10 for firmly positioning and holding the electric wire 50 that is not attached to the connector is relatively simple using the electric wire receiving portion 14 that has been generally used conventionally. And it can be obtained at low cost.

  In the above-described embodiment, the rod-shaped portion 16 has a substantially circular cross section, and the insertion holes 22h and 24h are substantially circular holes. However, the rod-shaped portion 16 is not necessarily required to have an elliptical shape, a polygonal shape, or the like. While forming in non-circular cross-sectional shape, you may form insertion holes 22h and 24h in which these are inserted in non-circular hole shapes, such as an ellipse and a polygonal shape. For example, as shown in FIG. 3, the rod-shaped portion 116 may be formed in an elliptical shape, and the insertion holes 122h and 124h may be formed in an elliptical hole shape. Thus, by forming at least one rod-like portion 16 in a substantially non-circular cross section, and forming at least one of the insertion holes 22h, 24h into which the rod-like portion 16 is inserted into a substantially non-circular hole, The rotation of the insertion holes 22h and 24h with respect to the rod-like portion 16 is suppressed, and the posture change of the elastic sheet member 20 with respect to the wire receiving portion 14 can be suppressed. In this case, the substantially non-circular cross section of the rod-like portion 16 and the substantially non-circular hole shapes of the insertion holes 22h and 24h do not necessarily have to be the same shape.
