In view of the above problems, it is an object of the present invention to provide an electric wire arrangement tool, an electric wire arrangement device, and an electric wire arrangement method capable of improving the assembling property of an electric wire to a terminal of a connector housing.

The present invention is an electric wire arranging tool for arranging an electric wire tip portion of an electric wire along an insertion direction at an electric wire connecting portion of a terminal accommodated in each of a plurality of terminal accommodating portions provided in a connector housing. A first positioning portion for gripping and positioning the housing and a second positioning portion for positioning a plurality of the electric wires at positions corresponding to the terminal accommodating portions are provided, and the first positioning portion and the first positioning portion are provided. The positioning portion is characterized in that at least one of the connector housing and the electric wire is slidably supported along the insertion direction.

The insertion direction is, for example, the moving direction of the electric wire when the electric wire is moved and the electric wire is inserted into the terminal accommodating portion, or the movement of the connector housing when the connector housing is moved and the electric wire is inserted into the terminal accommodating portion. It refers to the direction and so on.

According to the present invention, the assembling property of the electric wire to the terminal of the connector housing can be improved.
Specifically, by cooperating with the first positioning unit and the second positioning unit, the electric wire arrangement tool can easily face each terminal accommodating portion of the connector housing and each electric wire in the insertion direction. ..

Further, the first positioning portion and the second positioning portion allow the electric wire arrangement tool to insert the electric wire tip portion of the electric wire into each terminal accommodating portion of the connector housing substantially at the same time.

For example, by sliding the connector housing or sliding the electric wire together with the electric wire arrangement tool, the electric wire arrangement tool can insert the electric wire tip portion of the electric wire into each terminal accommodating portion of the connector housing at substantially the same time. it can.

Alternatively, by integrally sliding a plurality of electric wires with respect to the connector housing fixed so as not to be relatively movable and the electric wire arrangement, the electric wire arrangement can be used with respect to each terminal accommodating portion of the connector housing. The tip of the electric wire can be inserted at almost the same time.

As a result, the electric wire arranging tool can arrange the electric wire tip portion of the electric wire substantially simultaneously at the electric wire connecting portion of each terminal accommodated in the terminal accommodating portion. For this reason, the electric wire arranging tool can efficiently arrange the electric wires at the electric wire connecting portions of each terminal as compared with the case where the electric wires are held one by one with a chuck and arranged at the electric wire connecting portion of the terminal. ..
Therefore, the electric wire arrangement tool can improve the assembling property of the electric wire to the terminal of the connector housing.

As an aspect of the present invention, the second positioning portion positions and holds the position of the electric wire tip portion in the insertion direction, and the first positioning portion slides and moves along the insertion direction of the connector housing. It may be configured to hold.

According to this configuration, the electric wire arranging tool can collectively hold a plurality of electric wires whose positions in the insertion direction are positioned by the second positioning portion. Therefore, the electric wire arrangement tool can prevent the positional deviation of the relative position between the terminal accommodating portion and the electric wire tip portion.

Further, the first positioning unit allows the electric wire arrangement tool to relatively slide and move the connector housing and the electric wire held by the second positioning unit. At this time, since the position of the electric wire in the insertion direction is positioned, the electric wire arrangement tool can make the position of the electric wire tip portion in the insertion direction substantially the same for a plurality of electric wires inside the connector housing.

Therefore, in the electric wire arrangement tool, the electric wire tip portion of the electric wire can be surely arranged at the electric wire connection portion of each terminal.
Therefore, the electric wire arrangement tool can further improve the assembling property of the electric wire to the terminal.

Further, as an aspect of the present invention, the portion of the electric wire that is not inserted into the connector housing is regarded as a non-insertion portion of the electric wire, and the second positioning portion supports the electric wire tip portion of the electric wire and the terminal. A support portion for positioning the position of the tip portion of the electric wire with respect to the accommodating portion and a holding portion for holding the non-insertion portion of the electric wire positioned by the support portion are provided, and the support portion is the electric wire of the electric wire. In a state where the tip portion is started to be inserted into the connector housing, the support of the wire tip portion may be released.

Releasing the support of the electric wire tip means, for example, releasing the support of the electric wire tip by rotating or sliding the support with respect to the holding portion of the electric wire arrangement. Alternatively, it means that the support of the tip of the electric wire is released by removing the support from the holding portion of the electric wire arrangement.

According to this configuration, the electric wire arrangement can prevent the insertion of the electric wire tip portion into the terminal accommodating portion of the connector housing from being hindered by the contact between the support portion of the second positioning portion and the connector housing. Therefore, the electric wire arrangement tool can reliably arrange the electric wire tip portion of the electric wire with respect to the electric wire connection portion of each terminal.

Further, as an aspect of the present invention, the support portion of the second positioning portion may be pivotally supported with respect to the holding portion.
According to this configuration, the electric wire arrangement tool can easily support the electric wire tip portion and release the support as compared with the case where the support portion is attached to and detached from the holding portion of the second positioning portion.

Further, in the case of a support portion that can be attached to and detached from the holding portion of the second positioning portion, the position of the supporting portion with respect to the holding portion may be displaced each time the support portion is attached or detached.
On the other hand, since the support portion is pivotally supported with respect to the holding portion of the second positioning portion, the electric wire arrangement tool can suppress the positional deviation of the support portion with respect to the holding portion.

Therefore, the electric wire arrangement tool can surely suppress the misalignment of the electric wire with respect to the terminal accommodating portion of the connector housing.
Therefore, in the electric wire arrangement tool, the electric wire tip portion of the electric wire can be surely arranged with respect to the electric wire connection portion of each terminal, and the assembling property of the electric wire to the terminal can be further improved.

Further, as an aspect of the present invention, the support portion of the second positioning portion is formed by setting the length in the insertion direction shorter than the length of the wire tip portion of the electric wire in the insertion direction as the support length. The wire tip portion may be supported by the support length from the insertion portion side.
According to this configuration, the electric wire arrangement tool can support the electric wire tip portion of the electric wire in a state where the vicinity of the tip end portion of the electric wire is projected from the support portion of the second positioning portion.

Therefore, in the electric wire arrangement tool, the vicinity of the tip of the electric wire tip can be inserted into each terminal accommodating portion of the connector housing in a state where the electric wire tip of the electric wire is supported by the support.
Therefore, the electric wire arrangement tool can more reliably arrange the electric wire tip portion of the electric wire with respect to the electric wire connection portion of each terminal even when the support at the electric wire tip portion of the electric wire is released.

Further, as an aspect of the present invention, the support portion of the second positioning portion may be supported by the holding portion in a state where it can slide and move in a direction opposite to the insertion direction.
According to this configuration, the electric wire arrangement tool can slide and move the support portion of the second positioning portion, for example, by contact with the connector housing. Therefore, the electric wire arrangement can release the support of the electric wire tip portion as the electric wire is inserted into the terminal accommodating portion of the connector housing.

In other words, the wire arrangement tool may continue to support the wire tip of the wire by the support of the second positioning section until the wire tip of the wire is completely inserted into the terminal housing of the connector housing. it can.
As a result, the electric wire arrangement tool can reliably arrange the electric wire tip portion of the electric wire with respect to the electric wire connection portion of each terminal without dropping the electric wire tip portion from the connector housing.
Therefore, the electric wire arrangement tool can further improve the assembling property of the electric wire to the terminal of the connector housing.

Further, as an aspect of the present invention, the holding portion of the second positioning portion is a bottom plate portion on which the non-insertion portion of the plurality of electric wires is placed, and a top plate portion that sandwiches the electric wire between the bottom plate portions. And the hinge portion that pivotally supports the top plate portion with respect to the bottom plate portion so as to be able to open and close in the intersecting direction intersecting the insertion direction.

According to this configuration, the electric wire arrangement tool can easily hold the non-inserted portion of the electric wire and release the holding as compared with the case where the top plate portion is attached to and detached from the bottom plate portion. Therefore, the electric wire arrangement tool can further reliably improve the assembling property of the electric wire with respect to the terminal of the connector housing.

Further, as an aspect of the present invention, the second positioning portion is provided with a contact surface that comes into contact with the connector housing in a state where the wire tip portion of the wire is arranged at the wire connection portion of the terminal. May be good.
According to this configuration, the electric wire arrangement can regulate the relative sliding movement of the connector housing and the electric wire by the contact between the connector housing and the contact surface of the second positioning portion.

In other words, the electric wire arrangement tool can regulate the amount of the electric wire inserted into the terminal accommodating portion of the connector housing by the contact between the connector housing and the contact surface of the second positioning portion. Therefore, the electric wire arrangement tool can more reliably arrange the electric wire tip portion of the electric wire with respect to the electric wire connection portion of each terminal.
Therefore, the electric wire arrangement tool facilitates the reliable arrangement of the electric wire tip portion of the electric wire, and can further improve the assembling property of the electric wire to the terminal of the connector housing.
