Next, an example of an operation for arranging and holding the plurality of connectors 20 will be described.
First, the two electric wires 10 (hereinafter, referred to as the trunk line 10M) extended from the large connector are extended in one direction.
Then, the trunk line 10M is bent at a substantially right angle in the vicinity of the connector 20 (hereinafter referred to as the first connector 20F) connected to the terminal portion (see FIG. 1). Thereby, the first connector 20F is disposed sideways with respect to the main line 10M.

  Next, the wire pressing component 30 is attached to the first connector 20F. The wire holding part 30 is attached so that the bent portion of the trunk line 10M is accommodated in the insertion path 34 of the wire holding part 30. As a result, the bent portion of the trunk line 10M is restricted from being restored and deformed in a straight line, and the first connector 20F is held in a posture that is approximately 90 degrees lateral to the trunk line 10M.

At a position where the gap is opened, the first connector 20F and the second connector 20S are held in a posture that is approximately 90 degrees lateral to the trunk line 10M and facing the substantially same direction.

  The same operation is performed on the other connectors 20 in order, and a plurality of connectors 20 are arranged and held at predetermined positions. Thereby, the some connector 20 is hold | maintained with the attitude | position which orient | assigned the fitting part 24 with the other party connector to the substantially the same direction at substantially equal intervals.

Next, operations and effects of the embodiment configured as described above will be described.

Therefore, it is possible to cope with various arrangement forms of the connector 20 at low cost. Further, when the connector 20 is not arranged, the electric wire pressing component 30 need not be attached to the connector 20, so that the connector 20 can be shared between the case where it is arranged and the case where it is not arranged. Furthermore, it is possible to cope with an increase / decrease in the number of the electric wires 10 passed through the insertion passage 34 only by changing the size of the electric wire pressing component 30.

  Further, the electric wire 10 of the first connector 20F is bent so that the first connector 20F faces the same direction as the second connector 20S and the third connector 30T, and the electric wire holding component 30 is attached to the first connector 20F. Restoration deformation of the 20F electric wire 10 is limited. According to this configuration, the first connector 20F can be directed in the same direction as the second connector 20S and the third connector 30T.
