Description

  The present invention relates to a wire group holder and a wire harness applied to a wire harness in which a plurality of wire groups in which one wire is electrically connected to one wire at a splice portion are bundled.

2. Description of the Related Art Conventionally, a wire harness provided in a vehicle such as an automobile or a motorcycle is configured by bundling a plurality of electric wire groups in which branch lines are electrically connected to a main line at a splice portion.
The splice part is formed by joining the exposed conductors by peeling off the insulating layer at the middle part of the trunk line and the insulating layer at the tip part of the branch line by crimping with a caulking tool, welding, or soldering, For the purpose of insulating protection, for example, an insulating tape is wound around the splice portion.

  When there are a large number of splice parts in a group of electric wires bundled as a wire harness, the splice parts are usually arranged at regular intervals of several tens of millimeters or more so that the splice parts do not leak (for example, Patent Documents). 1).

JP 2005-302389 A

  However, in order to arrange the splice parts with a certain interval as in the prior art, the operator adjusts the position of the splice part so that the splice part of each electric wire group does not leak, and the wire harness Since it is necessary to route the wire harness, the manufacturing work of the wire harness becomes troublesome.

  In addition to this, since it is necessary to manually adjust the distance between the splice portions of each electric wire group, there is a possibility that the splice portion may be arranged at an interval that causes a leak due to an operator's mistake or the like. It will decline.

Furthermore, since the variation of the splice position becomes large at the time of splicing each electric wire group, it is necessary to route the wire harness by defining the interval between the splice parts of each electric wire group.
For example, when the interval between the splice parts is defined as 50 mm, only five splice parts can be arranged in a width of 200 mm. For this reason, the overflow electric wire group which cannot be attached within the width of 200 mm will be arrange | positioned in another place, and the freedom degree of arrangement | positioning of a splice part will be restrict | limited. Moreover, since the overflowing electric wire group is arranged in another place, the electric wire group becomes long, and the amount of electric wire increases accordingly, which increases the diameter of the wire harness and the manufacturing cost.

  On the other hand, when the interval between the splice parts is defined as 30 mm, seven splice parts can be arranged in a width of 200 mm. However, when the splice parts are arranged at short intervals, it is necessary to make adjustments for arranging the splice parts at short intervals, which makes the work of manufacturing the wire harness troublesome.

  The present invention has been made to solve the above-described conventional problems, and can improve the workability and quality of the wire harness manufacturing work and improve the degree of freedom in the arrangement of the splice parts. It is an object of the present invention to provide a wire group holder and a wire harness that can be made.

  In order to achieve the above object, the wire group holder according to the present invention is (1) holding a wire group that holds a plurality of wire groups each having a splice portion in which the other wire is electrically connected to one wire. 3 or more holding members having holding portions capable of receiving and holding the plurality of electric wire groups, and connecting portions to which the holding members are connected, the holding members being adjacent to each other. From one to which the splice part of one said electric wire group is arrange | positioned between members, and the splice part of several said electric wire group is connected to the said connection part with a fixed space | interval so that it may arrange | position in series with a fixed space | interval. It is configured.

  This holder holds the splice part because the holding member is connected to the connecting part at a constant interval so that the splice part of each wire group is arranged in series at a constant interval between adjacent holding members. It can be easily positioned between the members and held at regular intervals. For this reason, splice parts can be arranged at short intervals with a simple operation, and the workability of the wire harness manufacturing operation can be improved.

  In addition, even if there is a variation in the position of the splice part of each wire group in the splicing process, the operator can arrange the splice part between the holding members with a simple operation. It is possible to keep the interval between the splice portions at a predetermined interval which is a constant interval where no leakage occurs. For this reason, the quality of a wire harness can be improved.

  In addition, since the spacing between the splices of each wire group can be kept at a constant interval that does not cause leakage, the degree of freedom of the arrangement position of the splices can be increased, and the splices of each wire group can be kept within a certain distance. An optimal number of parts can be provided.

  As a result, it is possible to reduce the amount of electric wires by eliminating the need to place an overflowing electric wire group at a different position as in the conventional case, the diameter of the wire harness can be reduced, and the manufacturing cost of the wire harness Can be reduced.

In the electric wire group holder described in (1) above, (2) the holding member and the connecting portion are formed of an elastically deformable molded body.
Since the holding member and the connecting portion are elastically deformable, the holding member can deform the holding member when bundling a plurality of electric wire groups and winding the whole tape. For this reason, it is possible to prevent the electric wire group from being damaged by the holding member.
Moreover, since a holding | maintenance tool can change a holding member according to the wiring state of a wire harness, the softness | flexibility of a wire harness can be ensured.

  In the electric wire group holder according to the above (1) or (2), (3) the interval between the holding members is a splice part protection attached to the outer peripheral part in the axial direction of the electric wire group including the splice part. It is comprised from what is the same space | interval as the said axial direction length of a member.

In this holder, the distance between the holding members is the same as the length in the axial direction of the splice portion protective tape, so that both ends of the splice portion protective tape in the axial direction are in contact with the holding member. If it is positioned between, the splice portion can be easily positioned between the holding members and held at a constant interval.
For this reason, splice parts can be arranged at a short interval with a simpler operation, and the workability of the wire harness manufacturing operation can be further improved.

  Moreover, the wire harness which concerns on this invention is a wire harness provided with the holder of the electric wire group in any one of said (1)-(3), Comprising: (4) Between the said holding members adjacent, one The plurality of wire groups in which the splice portions of the wire group are arranged and the splice portions of the wire group are arranged in series at a constant interval, and the plurality of wire groups not held by the holder are the holding It is composed of things that are bundled together with the ingredients.

  Since this wire harness can easily position the splice between the holding members and hold it at a constant interval, it is possible to improve the workability and quality of the wire harness manufacturing work, The degree of freedom of arrangement of the splice part can be improved.

  Even if the positions of the splice parts 13A and 13B of the electric wire groups 10A and 10B vary in the splicing process, the operator can easily attach the splice parts 13A and 13B to the holding members 21A, 21B, and 21C. Can be placed between.

  For this reason, the space | interval of the splice parts 13A and 13B of the electric wire groups 10A and 10B can be maintained at a predetermined interval that is a constant interval that does not cause leakage. For this reason, the quality of the wire harness 1 can be improved.

In addition, since the intervals between the splice portions 13A and 13B of the wire groups 10A and 10B can be maintained at a constant interval that does not cause leakage, the degree of freedom of the arrangement positions of the splice portions 13A and 13B can be increased, and the constant width It is possible to provide an optimum number of splice parts 13A and 13B of the electric wire groups 10A and 10B.

When winding, the holding members 21A, 21B, and 21C can be deformed. For this reason, it is possible to prevent the wire groups 10A, 10B, and 16 from being damaged by the holding members 21A, 21B, and 21C.

  In addition, since the holding members 21A, 21B, and 21C can be deformed according to the wiring state of the wire harness 1, the flexibility of the wire harness 1 can be ensured.

  In addition, since the interval between the holding members 21A, 21B, and 21C of the present embodiment is set to the same interval as the width of the splice portion protection tapes 14A and 14B, both ends in the width direction of the splice portion protection tapes 14A and 14B are held. If the electric wire groups 10A, 10B are positioned between the holding members 21A, 21B, 21C so as to be in contact with the members 21A, 21B or the holding members 21B, 21C, the splice portions 13A, 13B of the holding members 21A, 21B, 21C It can be easily positioned between and held at regular intervals.
