　実施形態に係る端子付き電線１は、図１―４で示すように、導体としての芯線７と芯線７を被覆する絶縁体としての被覆体９とを備えた電線３と、電線３に設置されている端子５とを備える。 The electric wire with terminal 1 according to the embodiment is installed in an electric wire 3 including a core wire 7 as a conductor and a covering body 9 as an insulator covering the core wire 7, as shown in FIG. Terminal 5.
　電線３は、芯線７の長手方向の一端面と一端部側とが、被覆体９とは別の不透水性の部材（止水材、例えば、接着剤等の樹脂の膜）１１で被覆されている。これにより、不透水性部材１１で芯線７（電線３）の長手方向の一端が覆われているとともに、長手方向の一端から他端までのたとえば全長にわたって、芯線７が被覆体９で覆われている。 In the electric wire 3, one end surface and one end portion side in the longitudinal direction of the core wire 7 are covered with an impermeable member (water blocking material, for example, a resin film such as an adhesive) 11 different from the covering body 9. ing. Thereby, while the one end of the longitudinal direction of the core wire 7 (electric wire 3) is covered with the water-impermeable member 11, the core wire 7 is covered with the covering 9 over the full length from one end of the longitudinal direction to the other end. Yes.
　また、電線３では、長手方向の一端部の一部で芯線７が露出するように被覆体９と不透水性部材１１とが除去されている。すなわち、被覆体９の皮むきがされていることで被覆体除去部１３が形成されて、芯線７が露出している。 In the electric wire 3, the covering 9 and the water-impermeable member 11 are removed so that the core wire 7 is exposed at a part of one end in the longitudinal direction. That is, the covering body removing portion 13 is formed by peeling off the covering body 9, and the core wire 7 is exposed.
　端子５は、板状の電線圧着部１５を備える。そして、電線圧着部１５が電線３に圧着されることで、端子５が電線３の長手方向の一端部を保持している。さらに、電線３に被覆体除去部１３が形成されていることで、電線３の長手方向の一端部の一部で被覆体除去部１３から露出している芯線７が、電線圧着部１５に接触し電線圧着部１５で覆われてシールされている。 The terminal 5 includes a plate-shaped electric wire crimping portion 15. The terminal 5 holds one end in the longitudinal direction of the electric wire 3 by the electric wire crimping portion 15 being crimped to the electric wire 3. Furthermore, since the covering body removing portion 13 is formed on the electric wire 3, the core wire 7 exposed from the covering body removing portion 13 at a part of one end portion in the longitudinal direction of the electric wire 3 contacts the electric wire crimping portion 15. It is covered and sealed with a wire crimping portion 15.
　芯線７は、例えば、アルミニウム等の金属の細長い円柱状の素線を撚り合わせたことで形成されている。被覆体９は、筒状（たとえば円筒状）に形成されており、芯線７の長手方向の一端から芯線７の他端にわたって芯線７を覆っている。換言すれば、芯線７の長さと筒状の被覆体９の長さとはお互いが等しくなっており、筒状の被覆体９内を芯線７が通って延びている。芯線７の長手方向の一端と被覆体９の長手方向の一端とはお互いに一致している。芯線７の長手方向の他端と被覆体９の長手方向の他端とはお互いに一致している。芯線７の外周と被覆体９の内周とはお互いに一致している。また、電線３は、細長い円柱状に形成されている。 The core wire 7 is formed by, for example, twisting long and narrow cylindrical strands of metal such as aluminum. The covering body 9 is formed in a cylindrical shape (for example, a cylindrical shape) and covers the core wire 7 from one end in the longitudinal direction of the core wire 7 to the other end of the core wire 7. In other words, the length of the core wire 7 and the length of the cylindrical cover 9 are equal to each other, and the core wire 7 extends through the cylindrical cover 9. One end in the longitudinal direction of the core wire 7 and one end in the longitudinal direction of the covering body 9 coincide with each other. The other end in the longitudinal direction of the core wire 7 and the other end in the longitudinal direction of the covering body 9 coincide with each other. The outer periphery of the core wire 7 and the inner periphery of the covering body 9 coincide with each other. Further, the electric wire 3 is formed in an elongated cylindrical shape.
　なお、電線３の長手方向の他端部に別途端子が設置される等の処理がなされている場合には、被覆体９は、芯線７の長手方向の一端から芯線７の他端の近傍（上記処理がなされている部位）にわたって芯線７を覆っている。 In addition, when the process of installing a terminal separately in the other end part of the longitudinal direction of the electric wire 3 is made, the coating | coated body 9 is the vicinity of the other end of the core wire 7 from the longitudinal end of the core wire 7 ( The core wire 7 is covered over a portion where the above processing is performed.
　不透水性部材１１が設置される前の電線３は、芯線７と被覆体９とで構成されている。不透水性部材１１は、電線３に後から設けられたものである。不透水性部材１１を電線３に設けるときには、不透水性部材１１は液体状もしくは流動体状になっている。 The electric wire 3 before the impermeable member 11 is installed is composed of a core wire 7 and a covering body 9. The impermeable member 11 is provided on the electric wire 3 later. When the impermeable member 11 is provided on the electric wire 3, the impermeable member 11 is in a liquid form or a fluid form.
　不透水性部材１１が設置される前の電線３では、長手方向の一端と他端とで芯線７が露出している。この状態の電線３に不透水性部材１１を設けて不透水性部材１１を硬化させることで、芯線７の長手方向の一端面が不透水性部材１１で被覆されている。 In the electric wire 3 before the impermeable member 11 is installed, the core wire 7 is exposed at one end and the other end in the longitudinal direction. By providing the impermeable member 11 to the electric wire 3 in this state and curing the impermeable member 11, one end surface in the longitudinal direction of the core wire 7 is covered with the impermeable member 11.
　電線３に不透水性部材１１を設けることにより、長手方向の他端を除いて芯線７の総てが被覆体９と不透水性部材１１とで覆われてシールされている。 By providing the impermeable member 11 on the electric wire 3, all of the core wire 7 is covered and sealed with the covering 9 and the impermeable member 11 except for the other end in the longitudinal direction.
　不透水性部材１１は、電線３の長手方向の一端部に設けられている。すなわち、不透水性部材１１は、電線３の長手方向の一端と、この一端から他端に向かって所定の距離だけ離れた箇所との間にわたって連続し硬化した状態で設けられている。 The water-impermeable member 11 is provided at one end of the electric wire 3 in the longitudinal direction. That is, the water-impermeable member 11 is provided in a state of being continuously and cured between one end in the longitudinal direction of the electric wire 3 and a portion separated from the one end toward the other end by a predetermined distance.
　これにより、不透水性部材１１は円板状の底板部１７が電線３の長手方向の一端面に接して一端面を覆っており、円筒状の側板部１９が電線３の一端部で被覆体９の外周に接して被覆体９を覆っている。なお、電線３の被覆体９および硬化した不透水性部材１１は、可撓性（弾性）を有している。 Thereby, the water-impermeable member 11 has a disk-shaped bottom plate portion 17 in contact with one end surface in the longitudinal direction of the electric wire 3 to cover one end surface, and the cylindrical side plate portion 19 is covered with one end portion of the electric wire 3. The cover 9 is covered with the outer periphery of the cover 9. In addition, the covering body 9 of the electric wire 3 and the cured impermeable member 11 have flexibility (elasticity).
　長手方向の一端部の一部で被覆体９と硬化した不透水性部材１１とが除去されて、芯線７が被覆体除去部１３から露出している電線３について説明する。図３等に示すように、被覆体９と不透水性部材１１とが除去されている部分である被覆体除去部１３は、電線３の長手方向では、電線３の一端部の中間部で所定の長さにわたって存在しており、電線３の周方向では、半周程度の大きさになっている。これにより、被覆体９や不透水性部材１１を平面に展開すると、被覆体除去部１３は矩形状になっている。 The electric wire 3 in which the covering 9 and the cured impermeable member 11 are removed at a part of one end in the longitudinal direction and the core wire 7 is exposed from the covering removing portion 13 will be described. As shown in FIG. 3 and the like, the covering body removal portion 13, which is a portion from which the covering body 9 and the water-impermeable member 11 are removed, is predetermined at an intermediate portion of one end of the electric wire 3 in the longitudinal direction of the electric wire 3. In the circumferential direction of the electric wire 3 and has a size of about half a circumference. Thereby, when the covering body 9 and the water-impermeable member 11 are developed on a plane, the covering body removing portion 13 has a rectangular shape.
　なお、被覆体除去部１３と被覆体９との境界に位置している側壁部２１は、例えば、図８（ｃ）で示すように、被覆体９や不透水性部材１１の内外周に対して直交している。また、被覆体除去部１３の大きさは、端子付き電線１の電気的および機械的性能を確保することができる最小のものとすることが望ましい。 In addition, the side wall part 21 located in the boundary of the covering body removal part 13 and the covering body 9 is with respect to the inner periphery of the covering body 9 and the impermeable member 11, as shown in FIG.8 (c), for example. Are orthogonal. Moreover, it is desirable that the size of the covering body removing portion 13 be a minimum that can ensure the electrical and mechanical performance of the terminal-attached electric wire 1.
　端子５は、金属等の導電性の平板状の素材を所定形状にした後、この所定形状の素材を適宜折り曲げることで生成されている。端子５は、箱状の端子本体部２３と、板状の電線圧着部１５とを備える。電線圧着部１５は、端子本体部２３の一方の端から突出している。 The terminal 5 is generated by making a conductive flat plate material such as metal into a predetermined shape, and then bending the predetermined shape material appropriately. The terminal 5 includes a box-shaped terminal main body portion 23 and a plate-shaped wire crimping portion 15. The wire crimping portion 15 protrudes from one end of the terminal main body portion 23.
　電線圧着部１５の長さは、電線３の一端部の長さ（不透水性部材１１が設けられている箇所の長さ）と同程度になっている。板状の電線圧着部１５の幅は、電線３に設置されている不透水性部材１１の外周の長さよりも僅かに大きくなっている。 The length of the wire crimping portion 15 is approximately the same as the length of one end of the wire 3 (the length of the portion where the impermeable member 11 is provided). The width of the plate-shaped electric wire crimping portion 15 is slightly larger than the length of the outer periphery of the water-impermeable member 11 installed in the electric wire 3.
　圧着する前の電線圧着部１５の形状は、半円柱側面状もしくはＵ字板状（平面に描いたＵ字をその平面に対して直交する方向に所定の距離だけ移動したときに、Ｕ字の軌跡で現される立体形状）になっている。そして、不透水性部材１１が設置された電線３を電線圧着部１５に設置して、電線圧着部１５を圧着することで、電線圧着部１５が円筒状になり、電線３の一端部が、押圧されて若干変形し、電線圧着部１５で所定の押圧力をもって包み込まれ、電線３が端子５に一体的に設置される。 The shape of the wire crimping part 15 before crimping is a semi-cylindrical side surface or U-shaped plate (when the U-shape drawn on the plane is moved by a predetermined distance in a direction orthogonal to the plane, The three-dimensional shape shown by the trajectory). And the electric wire 3 in which the water-impermeable member 11 is installed is installed in the electric wire crimping portion 15, and the electric wire crimping portion 15 is crimped, so that the electric wire crimping portion 15 becomes cylindrical, and one end portion of the electric wire 3 is The wire is pressed and slightly deformed, and is wrapped with a predetermined pressing force at the wire crimping portion 15, so that the wire 3 is installed integrally with the terminal 5.
　電線圧着部１５を圧着することで電線３が端子５に一体的に設置されている状態である端子付き電線１では、電線圧着部１５の突出方向と電線３の長手方向とがお互いに一致している。また、電線３の長手方向の一端部の一部で被覆体９と不透水性部材１１とが除去されて露出している芯線７が、電線圧着部１５の幅方向（電線３の周方向）で、電線圧着部１５の中央部に位置し接触している。また、端子付き電線１では、電線３の長手方向の一端部の位置と電線圧着部１５の位置とがお互いにほぼ一致している。 In the terminal-attached electric wire 1 in which the electric wire 3 is integrally installed on the terminal 5 by crimping the electric wire crimping portion 15, the protruding direction of the electric wire crimping portion 15 and the longitudinal direction of the electric wire 3 coincide with each other. ing. Further, the core 7 exposed by removing the covering 9 and the water-impermeable member 11 at a part of one end in the longitudinal direction of the electric wire 3 is the width direction of the electric wire crimping portion 15 (circumferential direction of the electric wire 3). Therefore, it is located in the center part of the electric wire crimping part 15 and is in contact therewith. Moreover, in the electric wire 1 with a terminal, the position of the one end part of the longitudinal direction of the electric wire 3 and the position of the electric wire crimping part 15 are substantially in agreement with each other.
　さらに、電線３の長手方向の一端部の一部で被覆体９と不透水性部材１１とが除去されて形成された貫通孔である被覆体除去部１３の周囲の部位（被覆体９や不透水性部材１１の部位）は、被覆体除去部１３の縁の全周にわたって電線圧着部１５に密着している。これにより、電線３の外部から、被覆体除去部１３等を通って、電線３の内部（芯線７のところ）に水等が入り込まないようになっている。 Further, a portion around the covering removal portion 13 (through the covering 9 and the non-permeable portion) which is a through hole formed by removing the covering 9 and the water-impermeable member 11 at a part of one end in the longitudinal direction of the electric wire 3. The portion of the water-permeable member 11 is in close contact with the wire crimping portion 15 over the entire circumference of the edge of the covering removing portion 13. Accordingly, water or the like is prevented from entering the inside of the electric wire 3 (at the core wire 7) from the outside of the electric wire 3 through the covering body removing portion 13 or the like.
　なお、不透水性部材１１であるが、芯線７をシールしているのであれば、電線３の一端にのみ設けられた態様であってもよいし、電線３の長手方向において被覆体除去部１３の中間部で途切れていてもよい。また、被覆体除去部１３は、貫通孔に代えて切り欠きを設けてもよい。この場合、被覆体除去部１３は、貫通孔を、電線３の一端まで延長した形態になっており、Ｕ字状に形成されている。 In addition, although it is the water-impermeable member 11, if the core wire 7 is sealed, the aspect provided only in the end of the electric wire 3 may be sufficient, and the covering removal part 13 in the longitudinal direction of the electric wire 3 may be sufficient. It may be interrupted at the middle part. Further, the covering body removing portion 13 may be provided with a notch instead of the through hole. In this case, the covering body removing portion 13 has a shape in which the through hole extends to one end of the electric wire 3 and is formed in a U shape.
　次に、端子付き電線１の製造方法について説明する。 Next, the manufacturing method of the electric wire 1 with a terminal is demonstrated.
　まず、図２に示すように、電線３の一端部を未硬化の不透水性部材１１に浸して電線３の一端部に未硬化の不透水性部材１１を設け、この後、不透水性部材１１を硬化して、電線３の一端部を不透水性部材１１で覆う。 First, as shown in FIG. 2, one end of the electric wire 3 is immersed in an uncured impermeable member 11 to provide an uncured impermeable member 11 at one end of the electric wire 3. 11 is cured, and one end of the electric wire 3 is covered with the impermeable member 11.
　次に、図３に示すように、皮むき治具２５を用いて、被覆体除去部１３を形成する。皮むき治具２５は、基台２７と、一対の垂直皮むき刃２９と、一対の水平皮むき刃３１とを備える。基台２７に不透水性部材１１が設けられた電線３の一端部を設置し、基台２７に一対の垂直皮むき刃２９を近づけ、一対の水平皮むき刃３１同士をお互いに近づけることで、電線３の一端部での皮むきがなされる。このようにして、被覆体除去部１３が生成され、被覆体除去部１３のところで芯線７が露出する。 Next, as shown in FIG. 3, the covering removing part 13 is formed by using a peeling jig 25. The peeling jig 25 includes a base 27, a pair of vertical peeling blades 29, and a pair of horizontal peeling blades 31. By installing one end of the electric wire 3 provided with the water-impermeable member 11 on the base 27, the pair of vertical peeling blades 29 are brought close to the base 27, and the pair of horizontal peeling blades 31 are brought close to each other. The end of the electric wire 3 is peeled off. In this way, the covering body removing unit 13 is generated, and the core wire 7 is exposed at the covering body removing unit 13.
　続いて、図４に示す状態から、端子５に電線３を設置し、電線圧着部１５を圧着することで、端子付き電線１が生成される。 Subsequently, from the state shown in FIG. 4, the electric wire 3 is installed on the terminal 5 and the electric wire crimping portion 15 is crimped, whereby the electric wire 1 with a terminal is generated.
　実施形態に係る端子付き電線１によれば、芯線７の長手方向の一端面が不透水性部材１１で被覆されており、長手方向の一端部の一部で芯線７が露出するように電線３の被覆体９と不透水性部材１１とが除去されることにより被覆体除去部１３が形成されており、電線圧着部１５が圧着されることで、被覆体除去部１３のところで露出している芯線７が電線圧着部１５に接触して電線圧着部１５で覆われている。このため、電線３の内部への水の浸入を防止して芯線７の腐食を防止することができる。 According to the terminal-attached electric wire 1 according to the embodiment, the one end surface in the longitudinal direction of the core wire 7 is covered with the water-impermeable member 11, and the electric wire 3 is exposed so that the core wire 7 is exposed at a part of one end portion in the longitudinal direction. The covering body removing portion 13 is formed by removing the covering body 9 and the water-impermeable member 11, and the wire crimping portion 15 is crimped to be exposed at the covering body removing portion 13. The core wire 7 is in contact with the wire crimping portion 15 and is covered with the wire crimping portion 15. For this reason, the penetration | invasion of the water to the inside of the electric wire 3 can be prevented, and the corrosion of the core wire 7 can be prevented.
　また、端子５を電線３に設置するとき、従来例のような２回の圧着工程（図１０（ａ）に示す圧着工程と図１０（ｂ）に示す圧着工程）が不要になり、電線圧着部１５を丸めるような１回の圧着工程だけでよい。このため、電線３に端子５を設置する工程を簡素化することができ、端子付き電線１の製造コストを低減することができる。 Further, when the terminal 5 is installed on the electric wire 3, the two crimping steps (the crimping step shown in FIG. 10 (a) and the crimping step shown in FIG. 10 (b)) as in the conventional example become unnecessary, and the wire crimping is performed. Only a single crimping step is required to round the portion 15. For this reason, the process which installs the terminal 5 in the electric wire 3 can be simplified, and the manufacturing cost of the electric wire 1 with a terminal can be reduced.
　また、端子付き電線１によれば、電線３の一端の芯線７を不透水性部材１１によって覆うため、芯線７を確実にしかも容易にシールすることができる。また、電線３の一端の芯線７を不透水性部材１１で覆ってから、芯線７を露出させるための被覆体除去部１３を設けているので、マスキング効果により、端子５と芯線７との間に不透水性部材１１が入り込むことがなく、端子５と芯線７との導通状態が悪化することが防止される。 Moreover, according to the electric wire 1 with a terminal, since the core wire 7 at one end of the electric wire 3 is covered with the water-impermeable member 11, the core wire 7 can be reliably and easily sealed. Moreover, since the sheath removal part 13 for exposing the core wire 7 is provided after the core wire 7 at one end of the electric wire 3 is covered with the water-impermeable member 11, a gap between the terminal 5 and the core wire 7 is provided by a masking effect. Thus, the impervious member 11 does not enter and the conduction state between the terminal 5 and the core wire 7 is prevented from deteriorating.
　実施形態に係る端子付き電線１では、図１０（ｂ）で示すような従来例の端子付き電線３０１のように、端子の電線圧着部１５を圧着して電線の長手方向の一端部を包み込む必要が無い。このため、電線圧着部１５の形態を図５で示すようにすることができる。 In the electric wire with terminal 1 according to the embodiment, it is necessary to wrap one end portion in the longitudinal direction of the electric wire by crimping the electric wire crimping portion 15 of the terminal as in the conventional electric wire with terminal 301 as shown in FIG. There is no. For this reason, the form of the electric wire crimping part 15 can be made to show in FIG.
　すなわち、電線圧着部１５が、圧着本体部３３と、一対の基端側圧着部３５と、一対の先端側圧着部３７とを備えた構成にすることができる。 That is, the electric wire crimping portion 15 can include a crimping main body portion 33, a pair of proximal end crimping portions 35, and a pair of distal end side crimping portions 37.
　電線３に圧着される前の電線圧着部１５では、図５で示すように、圧着本体部３３が半円柱側面状に形成されている。また、基端側圧着部３５は、平板状に形成されており、電線圧着部１５の基端側の部位（端子本体部２３側の部位）から突出している。先端側圧着部３７も平板状に形成されており、電線圧着部１５の先端側の部位（端子本体部２３とは反対側の部位）から突出している。 In the electric wire crimping part 15 before being crimped to the electric wire 3, as shown in FIG. 5, the crimping main body part 33 is formed in a semi-cylindrical side surface shape. Further, the base end side crimping portion 35 is formed in a flat plate shape, and protrudes from a base end side portion (a portion on the terminal main body portion 23 side) of the wire crimping portion 15. The distal end side crimping portion 37 is also formed in a flat plate shape, and protrudes from a distal end side portion (a portion opposite to the terminal main body portion 23) of the wire crimping portion 15.
　電線圧着部１５を圧着した状態では、基端側圧着部３５が電線３の長手方向で被覆体除去部１３よりも一端側に位置している部位３９（図４参照）に係合しており、先端側圧着部３７が電線３の長手方向で被覆体除去部１３よりも他端側に位置している部位４１（図４参照）に係合している。 In a state where the wire crimping portion 15 is crimped, the proximal-side crimping portion 35 is engaged with a portion 39 (see FIG. 4) located on one end side of the covering body removing portion 13 in the longitudinal direction of the wire 3. The tip side crimping portion 37 is engaged with a portion 41 (see FIG. 4) located on the other end side of the covering body removing portion 13 in the longitudinal direction of the electric wire 3.
　端子５を用いた端子付き電線１によれば、電線圧着部１５が、圧着本体部３３と一対の基端側圧着部３５と一対の先端側圧着部３７とを備える。このため、端子５における電線３の圧着の具合を調整することが容易になる。たとえば、電線３の一端側では電線圧着部１５による電線３の保持力を強くし、電線３の一端から他端側に僅かに離れたところでは電線圧着部１５による電線３の保持力を弱くすることを容易に行うことができる。 According to the terminal-attached electric wire 1 using the terminal 5, the electric wire crimping portion 15 includes a crimping main body portion 33, a pair of proximal-side crimping portions 35, and a pair of distal-end-side crimping portions 37. For this reason, it becomes easy to adjust the crimping | compression-bonding condition of the electric wire 3 in the terminal 5. FIG. For example, the holding force of the electric wire 3 by the electric wire crimping portion 15 is increased at one end side of the electric wire 3, and the holding force of the electric wire 3 by the electric wire crimping portion 15 is weakened slightly away from one end of the electric wire 3 to the other end side. Can be done easily.
　また、端子付き電線１において、被覆体除去部１３の形態を図６等で示すように変更してもよい。すなわち、被覆体除去部１３を、芯線７から離れるにしたがって開口面積が広くなるように構成してもよい。 Moreover, in the electric wire 1 with a terminal, the form of the covering removal part 13 may be changed as shown in FIG. That is, you may comprise the covering body removal part 13 so that an opening area may become large as it leaves | separates from the core wire 7. FIG.
　さらに説明すると、図６で示す電線３では、被覆体除去部１３における被覆体９の側壁部（被覆体９の厚さ方向に展開している壁部）２１が勾配面になっていることで（図８（ａ）参照）、芯線７から離れるにしたがって被覆体除去部１３の開口面積が次第に広くなっている。 If it demonstrates further, in the electric wire 3 shown in FIG. 6, the side wall part (wall part currently developed in the thickness direction of the coating | coated body 9) 21 in the coating | coated body removal part 13 is a slope surface. (See FIG. 8A.) As the distance from the core wire 7 increases, the opening area of the covering body removal portion 13 gradually increases.
　具体的に説明すると、芯線７の長手方向に延びている中心軸を含む所定の平面による被覆体除去部１３の断面形状は、等脚台形状になっており、上底が芯線７側の位置しており、下底（上底よりに長い底辺）が、被覆体９の外周側に位置している。 More specifically, the cross-sectional shape of the covering removing portion 13 by a predetermined plane including the central axis extending in the longitudinal direction of the core wire 7 is an isosceles trapezoid, and the upper base is a position on the core wire 7 side. The lower base (the bottom longer than the upper base) is located on the outer peripheral side of the covering 9.
　なお、上記勾配面は、図３に示す垂直皮むき刃２９で形成された側壁部（電線３の長手方向で被覆体除去部１３の両端に位置している側壁部）２１にのみ形成されている。したがって、芯線７の長手方向に延びている中心軸に対して直交する平面による被覆体除去部１３の断面形状は、半円筒状（円筒をこの中心軸を含む所定の平面で２つに分割したときに得られる一方の立体の形状）になっている。 In addition, the said gradient surface is formed only in the side wall part (side wall part located in the both ends of the covering body removal part 13 in the longitudinal direction of the electric wire 3) 21 formed with the vertical peeling blade 29 shown in FIG. Yes. Therefore, the cross-sectional shape of the covering body removal part 13 by the plane orthogonal to the central axis extending in the longitudinal direction of the core wire 7 is semi-cylindrical (the cylinder is divided into two by a predetermined plane including the central axis. One of the three-dimensional shapes sometimes obtained).
　図６で示す電線３が使用されている端子付き電線１によれば、長手方向の一端部の一部で芯線７が露出するように生成された被覆体除去部１３の開口面積が、芯線７から離れるにしたがって広くなっているので、芯線７と端子５との接触面積が減少することが防止される。これにより、電気的および機械的性能が低下することが防止される。 According to the terminal-attached electric wire 1 in which the electric wire 3 shown in FIG. 6 is used, the opening area of the covering removing portion 13 generated so that the core wire 7 is exposed at a part of one end portion in the longitudinal direction is the core wire 7. Since it becomes wide as it leaves | separates from, it is prevented that the contact area of the core wire 7 and the terminal 5 reduces. Thereby, it is prevented that electrical and mechanical performance falls.
　詳しく説明すると、図８（ｃ）で示すように、被覆体９の側壁部２１が芯線７の長手方向に対して直交していると、電線圧着部１５を圧着して電線３に端子５を設置した後でも、被覆体９の側壁部２１が芯線７の長手方向に対して直交したままであり、芯線７と端子５との非接触の部位４５が、寸法ａ１にわたって形成される。 More specifically, as shown in FIG. 8C, when the side wall portion 21 of the covering 9 is orthogonal to the longitudinal direction of the core wire 7, the wire crimping portion 15 is crimped to connect the terminal 5 to the wire 3. Even after installation, the side wall portion 21 of the covering body 9 remains orthogonal to the longitudinal direction of the core wire 7, and a non-contact portion 45 between the core wire 7 and the terminal 5 is formed over the dimension a1.
　また、図８（ａ）で示すように、被覆体９の側壁部２１が芯線７の長手方向に対して傾いた勾配面になっていても、電線圧着部１５を圧着して電線３に端子５を設置したとき、図８（ｂ）で示すように、芯線７と端子５との非接触の部位４５が寸法ａ２にわたって形成される。しかし、電線圧着部１５を圧着したときに、被覆体９が被覆体除去部１３の縁のところで適宜つぶれるので、寸法ａ２＜寸法ａ１になり、芯線７と端子５との非接触の部位４５を従来よりも小さくすることができる。そして、被覆体除去部１３が設けられたことによって形成された芯線７の露出部位の長さＬに対する芯線７と端子５との非接触の部位４５の長さを短くすることができる。なお、図８（ａ）は、端子５の電線圧着部１５を圧着する前の状態を示している。また、図７、図８では不透水性部材１１の表示は省略している。 Further, as shown in FIG. 8A, even if the side wall portion 21 of the covering 9 is a sloped surface inclined with respect to the longitudinal direction of the core wire 7, the wire crimping portion 15 is crimped to the electric wire 3. When 5 is installed, as shown in FIG.8 (b), the non-contact site | part 45 of the core wire 7 and the terminal 5 is formed over the dimension a2. However, when the wire crimping portion 15 is crimped, the covering 9 is appropriately crushed at the edge of the covering removing portion 13, so that the dimension a <b> 2 <dimension a <b> 1, and the non-contact portion 45 between the core wire 7 and the terminal 5. It can be made smaller than before. And the length of the non-contact part 45 of the core wire 7 and the terminal 5 with respect to the length L of the exposed part of the core wire 7 formed by providing the covering body removal part 13 can be shortened. FIG. 8A shows a state before the wire crimping portion 15 of the terminal 5 is crimped. Moreover, the display of the water-impermeable member 11 is omitted in FIGS.
　なお、端子付き電線１において、不透水性部材１１を削除してもよい。 In addition, you may delete the impermeable member 11 in the electric wire 1 with a terminal.
　すなわち、長手方向の一端部の一部で芯線が露出するように被覆体が除去されている電線と、電線圧着部を備えこの電線圧着部が圧着されていることで、電線の長手方向の一端部の一部で露出している芯線が前記電線圧着部に接触し前記電線圧着部で覆われているとともに、前記電線の長手方向の一端部を保持している端子とを有し、長手方向の一端部の一部で前記芯線が露出するように生成された前記被覆体の除去部が、前記芯線から離れるにしたがって開口面積が広くなっているように構成してもよい。 That is, an electric wire from which a covering body is removed so that a core wire is exposed at a part of one end portion in the longitudinal direction, and an electric wire crimping portion are crimped so that one end in the longitudinal direction of the electric wire A core wire exposed at a part of the wire portion is in contact with the wire crimping portion and covered with the wire crimping portion, and has a terminal holding one end portion in the longitudinal direction of the wire. The covering body removal portion that is generated so that the core wire is exposed at a part of the one end portion may be configured such that the opening area increases as the distance from the core wire increases.
　この場合、図８（ｂ）で示すような電線圧着部１５の圧着がなされることで、電線３の長手方向の一端が不透水性部材１１を用いることなくシールされていることが望ましい。 In this case, it is desirable that one end in the longitudinal direction of the electric wire 3 is sealed without using the water-impermeable member 11 by crimping the electric wire crimping portion 15 as shown in FIG.
　本発明によれば、電線内部への水の浸入を、端子を用いて防止する端子付き電線において、電線に端子を設置する工程を簡素化することができる。 According to the present invention, it is possible to simplify the process of installing a terminal on an electric wire in a terminal-attached electric wire that prevents intrusion of water into the electric wire using a terminal.
