Abstract
In order to provide a technique for obtaining a wire harness with a shape closer to that when arranged in a vehicle, a wire harness in which three or more branch line portions branch from a trunk line portion and end portions of the branch line portions are respectively provided with connectors, includes: a holding member that holds the branch line portions such that a connector is positioned away from one of the three or more connectors in a first direction that is orthogonal to a terminal insertion direction and a connector is positioned away from that one connector in a second direction that is orthogonal to the first direction, when the trunk line portion is held such that the connectors are suspended.
Claims8
A wire harness in which at least three branch line portions branch from a trunk line portion and end portions of each of the branch line portions are respectively provided with connectors, comprising:
- a holder configured to hold the branch line portions such that a first connector of the connectors is positioned away from a second connector of the connectors in a first direction that is orthogonal to a terminal insertion direction and a third connector of the connectors is positioned away from that second connector in a second direction that is orthogonal to the first direction, when the trunk line portion is held such that the connectors are suspended,
- wherein the connectors are located in a positional relationship corresponding to that when arranged in a vehicle, when the trunk line portion is held such that the connectors are suspended,
- the holder includes branch line grouping members configured to be joined to each other,
- the branch line grouping members are respectively attached to the branch line portions, and, when the branch line grouping members are joined to each other, the branch line portions are located in a positional relationship corresponding to that when arranged in a vehicle, and
- the branch line grouping members include magnets, and the branch line grouping members are configured to be joined to each other using the magnets.
A wire harness production method comprising:
- preparing a plurality of connectors into which terminals of terminal-attached electric wires have been inserted;
- supporting the plurality of connectors such that a first connector of the plurality of connectors is positioned away from a second connector of the plurality of connectors in a first direction that is orthogonal to a terminal insertion direction and a third connector of the plurality of connectors is positioned away from the second connector in a second direction that is orthogonal to the first direction;
- measuring a dimension from the connectors and determining a branch position;
- holding the terminal-attached electric wires respectively inserted into the plurality of connectors, at the determined branch position, in a condition in which the plurality of connectors are supported;
- attaching branch line grouping members configured to be joined to each other, around the terminal-attached electric wires;
- and
- joining the branch line grouping members to each other,
- wherein the branch line grouping members are configured so as to be able to be joined to each other using a magnetic force.
A wire harness production method comprising:
- preparing a plurality of connectors into which terminals of terminal-attached electric wires have been inserted;
- supporting the plurality of connectors such that a first connector of the plurality of connectors is positioned away from a second connector of the plurality of connectors in a first direction that is orthogonal to a terminal insertion direction and a third connector of the plurality of connectors is positioned away from the second connector in a second direction that is orthogonal to the first direction;
- measuring a dimension from the connectors and determining a branch position;
- holding the terminal-attached electric wires respectively inserted into the plurality of connectors, at the determined branch position, in a condition in which the plurality of connectors are supported;
- attaching branch line grouping members configured to be joined to each other, around the terminal-attached electric wires, each branch line grouping member including a flat plate portion, an attachment portion, and a joint portion to attach the branch line grouping members to each other, each joint portion including a joint projection and a joint recess;
- and
- joining the branch line grouping members to each other by interlocking the joint projection to the joint recess on corresponding branch line grouping members,
- wherein the branch line grouping members are configured so as to be able to be attached to and detached from the terminal-attached electric wires, and the branch line grouping members are configured such that interlocking therebetween can be canceled, and
- the method further comprising, after holding the terminal-attached electric wires at the determined branch position, detaching the branch line grouping members from the terminal-attached electric wires, and canceling the interlocking between the branch line grouping members.
