Wiring module equipped with external cover member
A wiring module equipped with an external covering member includes an external covering pipe; a first conductive wire member that is inserted into the external covering pipe, a first end portion of the first conductive wire member extending from a first-end opening portion of the external covering pipe; a second conductive wire member that is connected to the first end portion of the first conductive wire member via a connection portion that is located outward of the first-end opening portion of the external covering pipe; and a bending mitigating member that is capable of undergoing elastic bending deformation more easily than the external covering pipe, a first end portion of the bending mitigating member being fixed to the first-end opening portion of the external covering pipe, and the bending mitigating member extending up to the connection portion or beyond the connection portion while surrounding the first conductive wire member.
1. A wiring module equipped with an external covering member, comprising:
an external covering pipe;
a first conductive wire member that includes a single-core wire constituted by a single conductor body, and that is inserted into the external covering pipe, a first end portion of the first conductive wire member extending from a first-end opening portion of the external covering pipe;
a second conductive wire member that includes a stranded wire constituted by twisting together a plurality of strands, and that is connected to the first end portion of the first conductive wire member via a connection portion located outward of the first-end opening portion of the external covering pipe; and
a bending mitigating member capable of undergoing elastic bending deformation more easily than the external covering pipe, a first end portion of the bending mitigating member being fixed to the first-end opening portion of the external covering pipe, and the bending mitigating member extending up to the connection portion or beyond the connection portion while surrounding the first conductive wire member outward of the first-end opening portion of the external covering pipe,
wherein the bending mitigating member includes a spiral wire-like body including portions that draw two spirals so as to surround the first conductive wire member, the portions being connected at a second end portion of the bending mitigating member.
2. The wiring module equipped with an external covering member according to claim 1 , wherein the first end portion of the bending mitigating member is fixed to the first-end opening portion of the external covering pipe in a state of being arranged inward of the first-end opening portion of the external covering pipe.
3. The wiring module equipped with an external covering member according to claim 2 ,
wherein a locking protrusion portion that protrudes outward is formed in the first end portion of the bending mitigating member,
a locking recessed portion into which the locking protrusion portion can be fitted is formed in the external covering pipe, and
in a state where the first end portion of the bending mitigating member is arranged inward of the first-end opening portion of the external covering pipe, the locking protrusion portion is fitted into the locking recessed portion, and the first end portion of the bending mitigating member is fixed to the first-end opening portion of the external covering pipe.
4. The wiring module equipped with an external covering member according to claim 1 , wherein the spiral wire-like body is formed by a wire-like body being wrapped in a spiral manner around a bar-shaped member.
5. The wiring module equipped with an external covering member according to claim 1 , wherein the spiral wire-like body is formed by a spiral-shaped slit being formed in a tube member.
