With reference to FIGS. 1 to 8, the terminal protection member 100 according to the embodiment and the manufacturing method thereof will be described. The terminal protection member 100 is a member that can protect the terminal 90 of the electric wire 9. 1 to 5 are views for explaining a method of manufacturing the terminal protection member 100. FIG. 6 and 7 are diagrams illustrating a method of manufacturing the electric wire 101 with the terminal protection member. FIG. 8 is a partially cutaway side view showing the terminal protection member 100 and the terminal protection member-attached electric wire 101.
　本実施形態の端末保護部材１００の製造方法は、スリット形成工程と折り曲げ工程とを備える。なお、ここでは、端末保護部材１００の製造方法は、さらに、塞ぎ工程を備える。以下、図１～５を参照しつつ、各工程の詳細について説明する。 The manufacturing method of the terminal protection member 100 of this embodiment includes a slit forming step and a bending step. Here, the method for manufacturing the terminal protection member 100 further includes a closing step. Hereinafter, the details of each process will be described with reference to FIGS.
　まず、スリット形成工程について説明する。図１～３に示されるように、スリット形成工程は、筒状の部材１０の一方の端部（以下、一方端部１１）から中間部分に亘ってスリット２を周方向に沿って複数設ける工程である。なお、ここでは、スリット形成工程は、押出成形によって得られた筒状の部材１０に、スリット２を周方向に沿って複数設ける工程である。 First, the slit forming process will be described. As shown in FIGS. 1 to 3, the slit forming step is a step of providing a plurality of slits 2 along the circumferential direction from one end portion (hereinafter referred to as one end portion 11) of the cylindrical member 10 to an intermediate portion. It is. Here, the slit forming step is a step of providing a plurality of slits 2 along the circumferential direction in the cylindrical member 10 obtained by extrusion molding.
　即ち、本実施形態では、図１に示されるように、押出成形によって得られる筒状の部材１０より、端末保護部材１００が作られる。筒状の部材１０を押出成形によって得る場合、製造コストを低減できる。なお、他の例として、筒状の部材１０が射出成形等により得られる部材である場合等も考えられる。 That is, in this embodiment, as shown in FIG. 1, the terminal protection member 100 is made from the cylindrical member 10 obtained by extrusion molding. When the cylindrical member 10 is obtained by extrusion molding, the manufacturing cost can be reduced. In addition, as another example, the case where the cylindrical member 10 is a member obtained by injection molding etc. can be considered.
　また、ここでは、筒状の部材１０は、例えば、塩化ビニル、ポリオレフィン又はポリプロピレン等の絶縁性を有する樹脂製又はゴム製の部材であることが考えられる。 Further, here, it is conceivable that the cylindrical member 10 is a resin or rubber member having insulating properties such as vinyl chloride, polyolefin, or polypropylene.
　スリット形成工程では、筒状の部材１０の一方端部１１から中間部分に亘ってスリット２が筒状の部材１０の周方向に沿って複数設けられる。より具体的には、ここでは、筒状の部材１０の全長の半分までスリット２が設けられる。なお、筒状の部材１０の全長とは、一方端部１１から一方端部１１に対する反対側の他方の端部（以下、他方端部１２）まで長さである。この場合、後述するベラ部６が過剰に長くなること及び短くなることを抑制できる。また、後述する折り曲げ部７を成す部分を十分な長さとすることができ、電線９の保持を十分に行うことができる。 In the slit forming step, a plurality of slits 2 are provided along the circumferential direction of the cylindrical member 10 from the one end 11 of the cylindrical member 10 to the intermediate portion. More specifically, here, the slit 2 is provided up to half of the entire length of the tubular member 10. The total length of the cylindrical member 10 is a length from one end 11 to the other end opposite to the one end 11 (hereinafter, the other end 12). In this case, it is possible to prevent the latera 6 described later from becoming excessively long and short. Moreover, the part which comprises the bending part 7 mentioned later can be made into sufficient length, and the electric wire 9 can fully be hold | maintained.
　また、ここでは、スリット２は、筋状のスリットである。そして、図３に示されるように、筒状の部材１０には、スリット２が２つ設けられる。また、ここでは、２つのスリット２は、周方向に沿って等間隔となるように設けられている。 Further, here, the slit 2 is a streak-like slit. As shown in FIG. 3, the cylindrical member 10 is provided with two slits 2. Here, the two slits 2 are provided at equal intervals along the circumferential direction.
　なお、別の例として、筒状の部材１０にスリット２が３つ以上設けられている場合も考えられる。しかしながら、後述するように、周方向において隣り合う２つのスリット２の間の部分（スリット間部分２０）が、ベラ部６又は折り曲げ部７を成す。従って、ベラ部６及び折り曲げ部７が周方向において過剰に細くなることを抑制するため、筒状の部材１０には、例えば、２～８つのスリット２が設けられることが考えられる。 As another example, a case in which three or more slits 2 are provided in the cylindrical member 10 may be considered. However, as will be described later, a portion between two slits 2 adjacent in the circumferential direction (inter-slit portion 20) forms the spatula portion 6 or the bent portion 7. Therefore, in order to prevent the spatula portion 6 and the bent portion 7 from becoming excessively thin in the circumferential direction, it is conceivable that the cylindrical member 10 is provided with, for example, two to eight slits 2.
　また、ここでは、複数のスリット２が、周方向に沿って等間隔に設けられているが、複数のスリット２が、不規則な間隔で設けられている場合も考えられる。 Further, here, the plurality of slits 2 are provided at equal intervals along the circumferential direction, but there may be a case where the plurality of slits 2 are provided at irregular intervals.
　また、ここでは、図２に示されるように、筒状の部材１０の他方端部１２を塞ぐ塞ぎ工程が行われる。塞ぎ工程は、スリット形成工程の前に行われても後で行われてもよい。 In addition, here, as shown in FIG. 2, a closing process for closing the other end 12 of the cylindrical member 10 is performed. The closing process may be performed before or after the slit forming process.
　塞ぎ工程では、他方端部１２の開口が閉じられる。ここでは、図２に示されるように、他方端部１２の内周面同士を近付け、内周面同士が接着剤によって接着若しくは熱溶接又は超音波溶接によって溶着されることで、他方端部１２が閉じられている。 In the closing process, the opening of the other end 12 is closed. Here, as shown in FIG. 2, the inner peripheral surfaces of the other end 12 are brought close to each other, and the inner peripheral surfaces are welded together by an adhesive or by heat welding or ultrasonic welding, thereby the other end 12. Is closed.
　スリット形成工程の後には、折り曲げ工程が行われる。図４，５に示されるように、折り曲げ工程は、複数（ここでは、２つ）のスリット間部分２０のうち少なくとも１つを、筒状の部材１０の内周側に折り曲げる工程である。 After the slit forming process, a bending process is performed. As shown in FIGS. 4 and 5, the bending step is a step of bending at least one of a plurality (here, two) inter-slit portions 20 toward the inner peripheral side of the cylindrical member 10.
　より具体的に説明する。ここでは、図３に示されるように、スリット２が周方向に沿って等間隔で２つ設けられる。これにより、筒状の部材１０の半周の部分を含むスリット間部分２０が２つ形成される。 More specific explanation. Here, as shown in FIG. 3, two slits 2 are provided at equal intervals along the circumferential direction. As a result, two inter-slit portions 20 including a half-circular portion of the cylindrical member 10 are formed.
　そして、この２つのスリット間部分２０のうちの一方（以下、上側スリット間部分２０１と称する）が、筒状の部材１０の内周側に折り曲げられる。より具体的には、ここでは、図４，５に示されるように、上側スリット間部分２０１の端面２１が他方端部１２側を向くように、根元から曲げられる。ここで、曲げられた上側スリット間部分２０１は、元の形状（一方側に延びた形状）に復帰しようとする弾性変形可能な部分である。このため、曲げられた上側スリット間部分２０１は元の形状に復帰しようとして、上側スリット間部分２０１の外周面の一部が、筒状の部材１０の内周面のうち２つのスリット間部分２０のうちの他方（以下、下側スリット間部分２０２と称する）側の面に押し付けられるように接触する。そして、この曲げられた上側スリット間部分２０１が、端末保護部材１００の折り曲げ部７を成す。 Then, one of the two inter-slit portions 20 (hereinafter referred to as the upper inter-slit portion 201) is bent toward the inner peripheral side of the cylindrical member 10. More specifically, here, as shown in FIGS. 4 and 5, the end surface 21 of the upper slit portion 201 is bent from the base so as to face the other end 12 side. Here, the bent upper slit portion 201 is an elastically deformable portion that attempts to return to its original shape (a shape extending to one side). For this reason, the bent upper inter-slit portion 201 tries to return to the original shape, and a part of the outer peripheral surface of the upper inter-slit portion 201 is part of the inner peripheral surface of the cylindrical member 10 between the two inter-slit portions 20. It contacts so that it may be pressed against the surface of the other side (henceforth the part 202 between lower slits) side. The bent upper slit portion 201 forms the bent portion 7 of the terminal protection member 100.
　一方、ここでは、下側スリット間部分２０２は、曲げられず、一方側に延びた形状とされる。そして、この一方側に延びた形状とされる下側スリット間部分２０２は、端末保護部材１００のベラ部６を成す。 On the other hand, here, the lower slit-to-slit portion 202 is not bent and has a shape extending to one side. The lower slit-to-slit portion 202 having a shape extending to the one side forms the spatula portion 6 of the terminal protection member 100.
　以上、本実施形態では、スリット形成工程、塞ぎ工程及び折り曲げ工程を経て、端末保護部材１００が作られる。従って、図４に示されるように、端末保護部材１００は、以下のように、筒状保護部５、ベラ部６及び折り曲げ部７を備える。 As described above, in the present embodiment, the terminal protection member 100 is manufactured through the slit forming process, the closing process, and the bending process. Therefore, as shown in FIG. 4, the terminal protection member 100 includes a cylindrical protection part 5, a spatula part 6, and a bent part 7 as follows.
　筒状保護部５は、電線９の端末９０を挿入可能な筒状の部分である。筒状保護部５の一方の端部５１には、ベラ部６と折り曲げ部７とが連なって形成されている。 The cylindrical protection part 5 is a cylindrical part into which the terminal 90 of the electric wire 9 can be inserted. At one end 51 of the cylindrical protection part 5, a spatula part 6 and a bent part 7 are formed continuously.
　一方、筒状保護部５の他方の端部５２（筒状の部材１０の他方端部１２と一致）は、閉じられている。この場合、この筒状保護部５に電線９が挿入される際の位置決めを簡単に行うことができる。詳細については、後述する。 On the other hand, the other end 52 of the cylindrical protection part 5 (matching with the other end 12 of the cylindrical member 10) is closed. In this case, positioning when the electric wire 9 is inserted into the cylindrical protection portion 5 can be easily performed. Details will be described later.
　ベラ部６は、筒状保護部５の一方の端部５１から一方側（一方の端部５１から他方の端部５２へ向かう方向に対する反対向きの方向）へ延びて形成されている。より具体的には、ここでは、筒状の部材１０の一方端部１１から中間部分に亘ってスリット２が複数（ここでは、２つ）形成され、複数（ここでは、２つ）のスリット２間の部分（スリット間部分２０）のうちの少なくとも１つ（ここでは、１つ）が、一方側へ延びた形状とされた部分がベラ部６である。 The spatula portion 6 is formed to extend from one end portion 51 of the cylindrical protection portion 5 to one side (a direction opposite to the direction from the one end portion 51 to the other end portion 52). More specifically, here, a plurality of (here, two) slits 2 are formed from one end 11 of the cylindrical member 10 to the intermediate portion, and a plurality of (here, two) slits 2 are formed. A portion in which at least one (here, one) of the intermediate portions (inter-slit portion 20) extends to one side is the spatula portion 6.
　ここでは、端末保護部材１００が、断面円形状の筒状の部材１０より作られるため、ベラ部６は断面円弧状に形成されていることが考えられる。ベラ部６の内周面側には、後述するように電線９が配設される。また、ここでは、周方向におけるベラ部６の領域が、全体の半分以上（ここでは、全体の半分）となるように形成されている。ここでは、２つのスリット２が、周方向に沿って等間隔となるように筒状の部材１０に設けられ、２つのスリット間部分２０のうちの１つ（下側スリット間部分２０２）が、ベラ部６を成すためである。この場合、少なくともベラ部６が電線９の周囲を半周程度覆うことができるため、ベラ部６と電線９とを安定して固定することができる。 Here, since the terminal protection member 100 is made of the cylindrical member 10 having a circular cross section, it is considered that the spatula portion 6 is formed in an arc shape in cross section. An electric wire 9 is disposed on the inner peripheral surface side of the spatula portion 6 as described later. Here, the area of the spatula portion 6 in the circumferential direction is formed so as to be more than half of the whole (here, half of the whole). Here, the two slits 2 are provided in the cylindrical member 10 so as to be equally spaced along the circumferential direction, and one of the two inter-slit portions 20 (the lower inter-slit portion 202) is This is to form the spatula part 6. In this case, since at least the spatula part 6 can cover the circumference of the electric wire 9 about a half circumference, the spatula part 6 and the electric wire 9 can be stably fixed.
　折り曲げ部７は、筒状保護部５の一方の端部５１から一方側へ延びる部分と筒状保護部５の内周側へ折り曲げられた部分とを含む。なお、折り曲げ部７において、筒状保護部５の一方の端部５１から一方側へ延びる部分と筒状保護部５の内周側へ折り曲げられた部分とが連なって形成されている。 The bent portion 7 includes a portion extending from one end 51 of the cylindrical protective portion 5 to one side and a portion bent toward the inner peripheral side of the cylindrical protective portion 5. In the bent portion 7, a portion extending from one end portion 51 of the cylindrical protective portion 5 to one side and a portion bent toward the inner peripheral side of the cylindrical protective portion 5 are formed in a row.
　ここでは、折り曲げ部７は、筒状保護部５の一方の端部５１から一方側へ延びる部分が筒状保護部５の内周側に折り曲げられた形状とされた部分である。より具体的には、ここでは、筒状の部材１０の一方端部１１から中間部分に亘ってスリット２が複数（ここでは、２つ）形成され、複数（ここでは、２つ）のスリット２間の部分（スリット間部分２０）のうちの少なくとも１つ（ここでは、１つ）が、筒状の部材１０の内周側へ折り曲げられた形状とされた部分が折り曲げ部７である。 Here, the bent portion 7 is a portion in which a portion extending from one end portion 51 of the cylindrical protective portion 5 to one side is bent to the inner peripheral side of the cylindrical protective portion 5. More specifically, here, a plurality of (here, two) slits 2 are formed from one end 11 of the cylindrical member 10 to the intermediate portion, and a plurality of (here, two) slits 2 are formed. The bent portion 7 is a portion in which at least one (here, one) of the intermediate portions (the slit-to-slit portion 20) is bent toward the inner peripheral side of the tubular member 10.
　ここでは、上述のように、折り曲げ部７は、弾性変形可能な部分であり、筒状保護部５の内周面にその一部が押し付けられるように接触している。折り曲げ部７と筒状保護部５の内周面との間には、後述するように電線９が挿入される。 Here, as described above, the bent portion 7 is an elastically deformable portion, and is in contact with the inner peripheral surface of the cylindrical protective portion 5 so that a part thereof is pressed. An electric wire 9 is inserted between the bent portion 7 and the inner peripheral surface of the cylindrical protective portion 5 as will be described later.
　ちなみに、ここでは、２つのスリット２が、周方向に沿って等間隔となるように筒状の部材１０に設けられ、２つのスリット間部分２０のうちの１つ（上側スリット間部分２０１）が、折り曲げ部７を成す。この場合、折り曲げ部７の幅を十分に確保できるため、電線９の保持が安定する。即ち、本実施形態の端末保護部材１００は、ベラ部６と電線９との固定を安定させつつ、折り曲げ部７による電線９の保持を安定させることができる。 Incidentally, here, the two slits 2 are provided in the cylindrical member 10 so as to be equally spaced along the circumferential direction, and one of the two inter-slit portions 20 (upper inter-slit portion 201) is provided. The bent portion 7 is formed. In this case, since the width | variety of the bending part 7 can fully be ensured, holding | maintenance of the electric wire 9 is stabilized. That is, the terminal protection member 100 of the present embodiment can stabilize the holding of the electric wire 9 by the bent portion 7 while stabilizing the fixing of the spatula portion 6 and the electric wire 9.
　次に、図６～８を参照しつつ、端末保護部材付電線１０１及び端末保護部材付電線１０１の製造方法について説明する。ここでは、端末保護部材付電線１０１の製造方法は、仮留め工程と固定工程とを備える。 Next, a method for manufacturing the electric wire 101 with terminal protective member 101 and the electric wire 101 with terminal protective member will be described with reference to FIGS. Here, the manufacturing method of the electric wire 101 with a terminal protection member includes a temporary fixing step and a fixing step.
　まず、端末保護部材付電線１０１における電線９について説明する。電線９は、例えば、芯線と芯線の周囲を覆う絶縁被覆とを備える絶縁電線であることが考えられる。ここでは、電線９の端部の絶縁被覆が除去され、芯線が露出している。 First, the electric wire 9 in the electric wire 101 with a terminal protection member will be described. It is conceivable that the electric wire 9 is an insulated wire including a core wire and an insulating coating covering the periphery of the core wire, for example. Here, the insulation coating at the end of the electric wire 9 is removed, and the core wire is exposed.
　ここでは、端末保護部材１００には、２つの電線９が挿入される。２つの電線９は、それぞれの端部の芯線同士が溶接等により接続されている。ここでは、この端部の芯線同士が接続された部分を含む部分が端末９０である。より具体的には、ここでは、端末９０は、電線９の端部の芯線同士が接続された部分及び絶縁被覆の一部を含んでいる。 Here, two electric wires 9 are inserted into the terminal protection member 100. As for the two electric wires 9, the core wires of each end part are connected by welding or the like. Here, the portion including the portion where the core wires at the end portions are connected is the terminal 90. More specifically, here, the terminal 90 includes a portion where the core wires at the ends of the electric wires 9 are connected to each other and a portion of the insulating coating.
　なお、別の例として、端末９０が、電線９の端部の芯線に接続された端子を含む場合も考えられる。また、１つ又は３つ以上の電線９が、端末保護部材１００に挿入される場合も考えられる。 As another example, the terminal 90 may include a terminal connected to the core wire at the end of the electric wire 9. Further, a case where one or three or more electric wires 9 are inserted into the terminal protection member 100 is also conceivable.
　仮留め工程について説明する。仮留め工程は、端末保護部材１００の筒状保護部５に、一方側から電線９の端末９０を挿入し、折り曲げ部７で仮留めする工程である。より具体的には、ベラ部６の内周面に電線９が配設されるように、電線９が筒状保護部５の内部へ一方側から挿入される。ここで、折り曲げ部７は、弾性変形可能な部分であり、筒状保護部５の内周面にその一部が押し付けられるように接触している。このため、折り曲げ部７と筒状保護部５の内周面との間に電線９の端末９０が挿入されると、電線９が折り曲げ部７と筒状保護部５の内周面とに挟まれる。これにより、電線９が端末保護部材１００に固定（仮留め）される。 The temporary fixing process will be described. The temporary fastening process is a process in which the terminal 90 of the electric wire 9 is inserted into the tubular protective part 5 of the terminal protective member 100 from one side and temporarily secured by the bent part 7. More specifically, the electric wire 9 is inserted into the cylindrical protection part 5 from one side so that the electric wire 9 is disposed on the inner peripheral surface of the spatula part 6. Here, the bent portion 7 is a portion that can be elastically deformed, and is in contact with the inner peripheral surface of the cylindrical protective portion 5 such that a part thereof is pressed. For this reason, when the terminal 90 of the electric wire 9 is inserted between the bent portion 7 and the inner peripheral surface of the cylindrical protective portion 5, the electric wire 9 is sandwiched between the bent portion 7 and the inner peripheral surface of the cylindrical protective portion 5. It is. Thereby, the electric wire 9 is fixed (temporarily fastened) to the terminal protection member 100.
　なお、ここでは、筒状保護部５の他方の端部５２が閉じられている。このため、電線９を筒状保護部５の内部へ挿入する際、所定量電線９が挿入されると、電線９の端末９０が筒状保護部５の他方の端部５２に接触する。このため、例えば、筒状保護部５の他方の端部５２に端末９０が接触するまで、電線９を筒状保護部５の内部に挿入するようにすることで、電線９の筒状保護部５への挿入量が不十分となること及び過剰となることを抑制できる。 Note that, here, the other end 52 of the cylindrical protective portion 5 is closed. For this reason, when inserting the electric wire 9 into the inside of the cylindrical protection part 5, if the predetermined amount of electric wires 9 are inserted, the terminal 90 of the electric wire 9 will contact the other end part 52 of the cylindrical protection part 5. FIG. For this reason, for example, until the terminal 90 comes into contact with the other end portion 52 of the cylindrical protection part 5, the electric wire 9 is inserted into the cylindrical protection part 5, thereby the cylindrical protection part of the electric wire 9. It can suppress that the insertion amount to 5 becomes inadequate and it becomes excess.
　次に、固定工程について説明する。固定工程は、筒状保護部５に端末９０が挿入され、折り曲げ部７で仮留めされた電線９とベラ部６とを固定する工程である。なお、ここでは、固定工程は、筒状保護部５に端末９０が挿入され、折り曲げ部７で仮留めされた電線９とベラ部６との周囲を一括して覆うように被覆部材８を取り付け固定する工程である。 Next, the fixing process will be described. The fixing step is a step in which the terminal 90 is inserted into the cylindrical protection portion 5 and the electric wire 9 and the spatula portion 6 temporarily fixed by the bent portion 7 are fixed. Here, in the fixing step, the terminal 90 is inserted into the cylindrical protection portion 5 and the covering member 8 is attached so as to cover the periphery of the wire 9 and the bellows portion 6 temporarily fixed by the bent portion 7. It is the process of fixing.
　より具体的には、ここでは、被覆部材８は、テープ状の部材であり、一方の面側に粘着層が形成されている。そして、被覆部材８の粘着層を内側にして、電線９及びベラ部６の周囲を一括して覆うように被覆部材８が巻き付けられる。なお、別の例として、被覆部材８が、粘着層を含まないテープである場合又はバンドである場合等も考えられる。 More specifically, here, the covering member 8 is a tape-like member, and an adhesive layer is formed on one surface side. And the covering member 8 is wound so that the circumference | surroundings of the electric wire 9 and the spatula part 6 may be covered collectively by making the adhesion layer of the covering member 8 inside. As another example, a case where the covering member 8 is a tape that does not include an adhesive layer or a band may be considered.
