Abstract
A wiring incorporated resin pipe includes a tubular shaped sheet formed in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction, a wiring unit arranged in the tubular shaped sheet along a longitudinal direction of the slit in an inner side of the slit and a resin material filled in a gap formed by matching surfaces of the slit of the tubular shaped sheet and the wiring unit to thereby seal the matching surfaces of the slit of the tubular shape sheet, in which conductive wires for wiring are laid inside the wiring unit in the longitudinal direction.

A wiring incorporated resin pipe comprising:
- a tubular shaped sheet formed in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction;
- a wiring unit arranged in the tubular shaped sheet along a longitudinal direction of the slit in an inner side of the slit;
- and
- a resin material filled in a gap formed by matching surfaces of the slit of the tubular shaped sheet and the wiring unit to thereby seal the matching surfaces of the slit of the tubular shaped sheet,
- wherein conductive wires for wiring are laid inside the wiring unit in the longitudinal direction,
- the wiring unit has a holder in which grooves into which conductive wires for wiring are inserted are formed, and
- the resin material is filled in the grooves into which the conductive wires are inserted.
A method of manufacturing a wiring incorporated resin pipe comprising:
- arranging a thermoplastic sheet having a rectangular shape to be in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction;
- arranging a wiring unit in which conductive wires for wiring are laid in a longitudinal direction in the thermoplastic sheet in an inner side of the slit along the longitudinal direction of the slit, the conductive wires being inserted into grooves formed in a holder of the wiring unit;
- and
- filling a resin material in a gap formed by matching surfaces of the slit of the thermoplastic sheet and the wiring unit to integrate the thermoplastic sheet with the wiring unit, and filling the resin material in the grooves into which the conductive wires are inserted.
A method of manufacturing a wiring incorporated resin pipe comprising:
- arranging a thermoplastic sheet having a rectangular shape to be in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction on a peripheral surface of a core bar of a molding device, the molding device having a first mold, a second mold and the core bar arranged inside the second mold in a closed state of the first and second molds;
- arranging a wiring unit in which conductive wires for wiring are laid in a longitudinal direction on the core bar in an inner side of the slit along the longitudinal direction of the slit;
- injecting a molten resin material into a gap for joining formed by matching surfaces of the slit of the sheet arranged in the approximately tubular shape and the wiring unit after closing the first mold and the second mold;
- and
- opening the molds after the resin material injected by injection is reduced in temperature and solidified and removing the core bar from a molded product in which the sheet and the wiring unit are integrated by the resin material,
- wherein the wiring unit is arranged on the core bar by respectively arranging the conductive wires in plural grooves formed in a holder of the wiring unit.
