次に、図２〜図４を参照して、プロテクタ１０の製造方法について説明する。   Next, a method for manufacturing the protector 10 will be described with reference to FIGS.

図２に示すように、プロテクタ１０の製造方法の電線を挿通する工程において、熱可塑性樹脂を用いて作成されたプロテクタ母材１６が用意される。このプロテクタ母材１６は、四角形の筒形状であって、直線的に成形されている。そして、プロテクタ母材１６の内側に形成されている電線収容部１７内に電線３１が挿通される。プロテクタ母材１６は、配索に応じて、一端寄りに第１屈曲部１４が設定され、他端寄りに第２屈曲部１５が設定される。   As shown in FIG. 2, a protector base material 16 made using a thermoplastic resin is prepared in the step of inserting the electric wire in the manufacturing method of the protector 10. The protector base material 16 has a rectangular cylindrical shape and is linearly formed. And the electric wire 31 is penetrated in the electric wire accommodating part 17 currently formed inside the protector base material 16. FIG. The protector base material 16 has a first bent portion 14 set near one end and a second bent portion 15 set near the other end in accordance with the routing.

図３に示すように、プロテクタ１０の製造方法の加熱工程において、プロテクタ母材１６の第１屈曲部１４と第２屈曲部１５とが加熱される。加熱には、環形状のヒーターである加熱装置１８が用いられる。加熱装置１８は、不図示の加熱制御回路に電気的に接続されているとともに、スライド移動手段に機械的に結合されているために、プロテクタ母材１６に外装されてから、スライド移動手段によって第１屈曲部１４と第２屈曲部１５とを移動され、それぞれの位置で加熱制御回路より与えられた制御信号によって第１屈曲部１４と第２屈曲部１５とを加熱する。第１屈曲部１４と第２屈曲部１５とは、加熱によって軟化を始める。なお、加熱装置１８は、上記して電気的手段に代えて、流体を用いても良い。   As shown in FIG. 3, in the heating process of the manufacturing method of the protector 10, the 1st bending part 14 and the 2nd bending part 15 of the protector base material 16 are heated. For the heating, a heating device 18 which is an annular heater is used. The heating device 18 is electrically connected to a heating control circuit (not shown) and is mechanically coupled to the slide moving means. Therefore, the heating device 18 is externally attached to the protector base material 16 and then moved by the slide moving means. The first bent portion 14 and the second bent portion 15 are moved, and the first bent portion 14 and the second bent portion 15 are heated by a control signal given from the heating control circuit at each position. The first bent portion 14 and the second bent portion 15 begin to soften by heating. The heating device 18 may use a fluid instead of the electrical means as described above.

図４に示すように、プロテクタ１０の製造方法の折曲工程において、プロテクタ母材１６の第１屈曲部１４と第２屈曲部１５とが折り曲げ成形される。折り曲げ成形には、固定側治具１９と、可動側治具２０とが用いられる。固定側治具１９は、プロテクタ母材１６の一端側を把持し、可動側治具２０は、プロテクタ母材１６の中央部を把持し、可動側治具２０が固定側治具１９に対して上方に円軌道で上昇される。これにより、プロテクタ母材１６は、一端側に一端側筒部１１が形成され、この一端側筒部１１の端部において第１屈曲部１４を介して他端側が斜め上方に向けて折り曲げ成形された、図１に示すプロテクタ１０に成形される。   As shown in FIG. 4, in the bending process of the manufacturing method of the protector 10, the 1st bending part 14 and the 2nd bending part 15 of the protector base material 16 are bend-molded. For bending, a fixed side jig 19 and a movable side jig 20 are used. The fixed-side jig 19 grips one end side of the protector base material 16, the movable-side jig 20 grips the central portion of the protector base material 16, and the movable-side jig 20 is against the fixed-side jig 19. It is raised upward in a circular orbit. As a result, the protector base material 16 has the one end side cylindrical portion 11 formed on one end side, and the other end side is bent upward and obliquely upward via the first bent portion 14 at the end portion of the one end side cylindrical portion 11. Further, the protector 10 shown in FIG. 1 is formed.

そして、次に、固定側治具１９が斜め上方に向けて折り曲げ成形されたプロテクタ母材１６の中央部を把持し、可動側治具２０がプロテクタ母材１６の他端側を把持し、可動側治具２０が固定側治具１９に対して下方に円軌道で下降される。これにより、プロテクタ母材１６は、他端側に他端側筒部１３が形成され、この他端側筒部１３の端部において第２屈曲部１５を介して斜め下方に向けて折り曲げ成形された中央側筒部１２が形成される。   Then, the fixed side jig 19 grips the central portion of the protector base material 16 that is bent obliquely upward, and the movable side jig 20 grips the other end side of the protector base material 16 to move the protector base material 16. The side jig 20 is lowered with a circular path downward with respect to the fixed side jig 19. Thereby, the other end side cylinder part 13 is formed in the other end side, and the protector base material 16 is bend | folded and formed toward the diagonally downward direction via the 2nd bending part 15 in the edge part of this other end side cylinder part 13. FIG. A central cylinder portion 12 is formed.

このように、プロテクタ１０は、電線３１を挿通してある状態から、加熱後に折り曲げ成形されるだけで、３次元の形状に簡単に製造される。   Thus, the protector 10 is easily manufactured in a three-dimensional shape from the state in which the electric wire 31 is inserted only by being bent after heating.

上述したように、本実施形態のプロテクタ構造によれば、プロテクタ１０は、電線３１を挿通しているプロテクタ母材１６の第１屈曲部１４と第２屈曲部１５とを折り曲げ成形されてなるために、従来のものように、予め所定の形状に成形する必要がなくなるので部品管理に多くの工数を必要としない。また、複雑な金型を用いる必要がないのでコスト面で有利である。そして、ロック等を必要としないので作業性を良好にすることができる。   As described above, according to the protector structure of the present embodiment, the protector 10 is formed by bending the first bent portion 14 and the second bent portion 15 of the protector base material 16 through which the electric wire 31 is inserted. In addition, unlike the conventional one, it is not necessary to form in a predetermined shape in advance, so that a lot of man-hours are not required for component management. Further, there is no need to use a complicated mold, which is advantageous in terms of cost. And since a lock | rock etc. are not required, workability | operativity can be made favorable.

また、本実施形態のプロテクタ１０の製造方法によれば、配索に応じたプロテクタ母材１６の第１屈曲部１４と第２屈曲部１５とを加熱する加熱工程と、加熱された第１屈曲部１４と第２屈曲部１５とを折り曲げ成形する折曲工程とを、従来と同等の設備で行うことができるために、新規な設備投資を必要とせずに、コスト面で有利に製造することができる。   Moreover, according to the manufacturing method of the protector 10 of this embodiment, the heating process which heats the 1st bending part 14 and the 2nd bending part 15 of the protector base material 16 according to routing, and the heated 1st bending Since the bending step of bending the portion 14 and the second bent portion 15 can be performed with the same equipment as the conventional one, it is advantageous to manufacture in terms of cost without requiring a new equipment investment.

（第２実施形態）
次に、図５及び図６を参照して、本発明のプロテクタ構造及びプロテクタの製造方法の第２実施形態について説明する。図５は本発明の第２実施形態に係るプロテクタの製造方法の電線を挿通した工程の外観斜視図、図６はプロテクタの製造方法の加熱工程の外観斜視図である。なお、以下の第２実施形態において、上述した第１実施形態と重複する構成要素や機能的に同様な構成要素等については、図中に同一符号あるいは相当符号を付すことによって説明を簡略化あるいは省略する。 (Second Embodiment)
Next, with reference to FIG.5 and FIG.6, 2nd Embodiment of the protector structure of this invention and the manufacturing method of a protector is described. FIG. 5 is an external perspective view of a process of inserting a wire in a protector manufacturing method according to the second embodiment of the present invention, and FIG. 6 is an external perspective view of a heating process of the protector manufacturing method. Note that, in the following second embodiment, components that are the same as those in the above-described first embodiment, functionally similar components, and the like are simplified by adding the same reference signs or equivalent signs in the drawings, or Omitted.

図５に示すように、本発明の第２実施形態であるプロテクタ１０の製造方法の電線を挿通する工程において、プロテクタ母材１６の第１屈曲部１４と第２屈曲部１５は、予め光（例えば、赤外線光）の照射に伴い発熱するカーボン等の発熱源が混入された樹脂材料４０で成形されている。このプロテクタ母材１６内に電線３１が挿通される。   As shown in FIG. 5, in the step of inserting the electric wire of the manufacturing method of the protector 10 according to the second embodiment of the present invention, the first bent portion 14 and the second bent portion 15 of the protector base material 16 are previously light ( For example, the resin material 40 is mixed with a heat source such as carbon that generates heat upon irradiation with infrared light. An electric wire 31 is inserted into the protector base material 16.

図６に示すように、プロテクタ１０の製造方法の加熱工程において、樹脂材料４０で成形されたプロテクタ母材１６の第１屈曲部１４と第２屈曲部１５とに、レーザー照射口４２から光４３（例えば、赤外線光）が照射される。レーザー照射口４２は、不図示のレーザー発生手段に電気的に接続されているとともに、不図示の照射口移動手段によってプロテクタ母材１６の筒方向に移動されるために、樹脂材料４０に均一に光４３が照射され、樹脂材料４０が溶融を始める。光４３の照射は、例えば数秒〜数十秒程度の短時間である。   As shown in FIG. 6, in the heating process of the manufacturing method of the protector 10, the light 43 from the laser irradiation port 42 is applied to the first bent portion 14 and the second bent portion 15 of the protector base material 16 molded with the resin material 40. (For example, infrared light) is irradiated. The laser irradiation port 42 is electrically connected to a laser generating unit (not shown) and is moved in the cylindrical direction of the protector base material 16 by an irradiation port moving unit (not shown). The light 43 is irradiated, and the resin material 40 starts to melt. The irradiation of the light 43 is for a short time, for example, about several seconds to several tens of seconds.

本実施形態のプロテクタ１０の製造方法では、以後の折曲工程を第１実施形態と同様に行うために、その説明は省略するが、第１屈曲部１４及び第２屈曲部１５を形成する樹脂材料４０の発熱により第１屈曲部１４及び第２屈曲部１５部分が軟化され、折り曲げ成形されることで、図１に示す一端側筒部１１と中央側筒部１２と他端側筒部１３とが形成されたプロテクタ１０が製造される。なお、プロテクタ母材１６全体を樹脂材料４０で成形して、屈曲が必要な第１屈曲部１４及び第２屈曲部１５だけに光４３を照射するようにしても良い。   In the manufacturing method of the protector 10 of this embodiment, since the subsequent bending process is performed in the same manner as in the first embodiment, the description thereof is omitted, but the resin forming the first bent portion 14 and the second bent portion 15 is used. The first bent portion 14 and the second bent portion 15 are softened by the heat generation of the material 40, and are bent and formed, so that the one end side cylinder portion 11, the center side cylinder portion 12, and the other end side cylinder portion 13 shown in FIG. Is formed. Alternatively, the entire protector base material 16 may be formed of the resin material 40 so that only the first bent portion 14 and the second bent portion 15 that need to be bent are irradiated with the light 43.

本実施形態のプロテクタ構造によれば、プロテクタ１０は、電線３１を挿通しているプロテクタ母材１６の少なくとも第１屈曲部１４と第２屈曲部１５が、発熱源の混入された樹脂材料４０で成形されており、この第１屈曲部１４と第２屈曲部１５部分に光４３を照射することで、第１屈曲部１４及び第２屈曲部１５を折り曲げ成形することができる。これにより、従来のものように、予め所定の形状に成形する必要がなくなるので部品管理に多くの工数を必要としない。また、折り曲げ成形であるために、複雑な金型を用いる必要がないのでコスト面で有利である。そして、ロック等を必要としないので作業性を良好にすることができる。   According to the protector structure of the present embodiment, the protector 10 includes the resin material 40 in which at least the first bent portion 14 and the second bent portion 15 of the protector base material 16 through which the electric wire 31 is inserted are mixed with a heat generation source. The first bent portion 14 and the second bent portion 15 can be bent and formed by irradiating the first bent portion 14 and the second bent portion 15 with light 43. As a result, unlike the conventional one, it is not necessary to form in a predetermined shape in advance, so that many man-hours are not required for component management. Moreover, since it is a bending molding, it is not necessary to use a complicated mold, which is advantageous in terms of cost. And since a lock | rock etc. are not required, workability | operativity can be made favorable.
