本発明の態様によれば、電線内部への水の浸入を防止してい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という効果を奏する。
According to the aspect of the present invention, there is an effect that the process of installing the terminal on the electric wire can be simplified in the electric wire with the terminal that prevents the water from entering the electric wire.
実施形態に係る端子付き電線１は、図１―５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、シールシート５と、端子７を備える。
As shown in FIG. 1-5, the electric wire with terminal 1 according to the embodiment includes 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, a seal sheet 5, A terminal 7 is provided.
電線３は、この長手方向の一端部で被覆体９が除去されていることで、芯線１１が露出している。
The wire 3 has the core wire 11 exposed by removing the covering 9 at one end in the longitudinal direction.
シールシート５には、開口部１３が形成されている。そして、芯線１１の一部が開口部１３を介して露出するようにシールシート５が電線３の長手方向の一端部に設置されて、被覆体９が除去されている部位を覆っている。
The opening 13 is formed in the seal sheet 5. And the sealing sheet 5 is installed in the one end part of the longitudinal direction of the electric wire 3 so that a part of core wire 11 may be exposed through the opening part 13, and has covered the site | part from which the coating body 9 was removed.
端子７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、シールシート５の開口部１３を介して露出している芯線１１が電線圧着部１５に接触して電線圧着部１５で覆われてシールされている。また、電線圧着部１５が電線３に圧着されることで、端子７が電線３の長手方向の一端部を保持している。
The terminal 7 includes a plate-shaped electric wire crimping portion 15. And the wire crimping part 15 is crimped | bonded to the electric wire 3, and the core wire 11 exposed through the opening part 13 of the seal sheet 5 contacts the wire crimping part 15, and is covered with the wire crimping part 15 and sealed. Has been. Further, the wire crimping portion 15 is crimped to the electric wire 3 so that the terminal 7 holds one end portion of the electric wire 3 in the longitudinal direction.
芯線１１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、不透水性の合成樹脂等の絶縁性材料で筒状（たとえば円筒状）に形成されており、芯線１１の長手方向の一端の近傍から芯線１１の他端にわたって芯線１１を覆っている。換言すれば、筒状の被覆体９の長さが芯線１１の長さがよりも僅かに短くなっており、筒状の被覆体９内を芯線１１が通って延びている。被覆体９の長手方向の一端は、芯線１１の長手方向の一端よりも僅かに長手方向の他端側に位置しており、芯線１１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。これにより、シールシート５を設置する前の状態では、芯線１１の長手方向の一端と被覆体９の長手方向の一端との間（電線３の長手方向の一端部）で、芯線１１が露出している。
The core wire 11 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) with an insulating material such as an impermeable synthetic resin, and covers the core wire 11 from the vicinity of one end in the longitudinal direction of the core wire 11 to the other end of the core wire 11. ing. In other words, the length of the cylindrical cover 9 is slightly shorter than the length of the core wire 11, and the core wire 11 extends through the cylindrical cover 9. One end in the longitudinal direction of the covering body 9 is located slightly on the other end side in the longitudinal direction from one end in the longitudinal direction of the core wire 11, and the other end in the longitudinal direction of the core wire 11 and the other in the longitudinal direction of the covering body 9. The edges coincide with each other. Thereby, in the state before installing the seal sheet 5, the core wire 11 is exposed between one end in the longitudinal direction of the core wire 11 and one end in the longitudinal direction of the covering 9 (one end portion in the longitudinal direction of the electric wire 3). ing.
なお、芯線１１が露出していない電線３の部位では、芯線１１の外周と被覆体９の内周とはお互いに接触している。また、電線３は、細長い円柱状に形成されている。
In addition, in the part of the electric wire 3 where the core wire 11 is not exposed, the outer periphery of the core wire 11 and the inner periphery of the covering 9 are in contact with each other. Further, the electric wire 3 is formed in an elongated cylindrical shape.
また、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１１の長手方向の一端の近傍から芯線の１１他端の近傍（上記処理がなされている他端の部位）にわたって芯線１１を覆っている。
In addition, when a process is performed such that a terminal is separately installed at the other end portion in the longitudinal direction of the electric wire 3, the covering body 9 is connected from the vicinity of one end in the longitudinal direction of the core wire 11 to the other end of the core wire 11. The core wire 11 is covered over the vicinity (the part of the other end where the said process is made).
シールシート５が設置される前の電線３は、芯線１１と被覆体９とを備える。シールシート５は、電線３に後から設けられる。シールシートが設置される前の電線３では、長手方向の一端部で芯線１１が露出している。電線３にシールシート５を設けることにより、芯線１１の長手方向の一端面を含む一端部が、シールシート５の開口部１３を除いてシールシート５で被覆されている。
The electric wire 3 before the seal sheet 5 is installed includes a core wire 11 and a covering body 9. The seal sheet 5 is provided on the electric wire 3 later. In the electric wire 3 before the seal sheet is installed, the core wire 11 is exposed at one end in the longitudinal direction. By providing the seal sheet 5 on the electric wire 3, one end portion including one end surface in the longitudinal direction of the core wire 11 is covered with the seal sheet 5 except for the opening 13 of the seal sheet 5.
電線３にシールシート５を設けることで、シールシート５の開口部１３と電線３の長手方向の他端面を除いて芯線１１の総てが被覆体９とシールシート５とで覆われてシールされている。
By providing the sealing sheet 5 on the electric wire 3, all of the core wire 11 is covered and sealed with the covering body 9 and the sealing sheet 5 except for the opening 13 of the sealing sheet 5 and the other end surface in the longitudinal direction of the electric wire 3. ing.
電線３に設置される前のシールシート５は、例えば、絶縁性の合成樹脂等の不透水性の材料で所定の形状（たとえば矩形な板状）に形成されており、開口部１３も矩形状に形成されており、シールシート５の中央部でシールシート５をこの厚さ方向に貫通している。
The seal sheet 5 before being installed on the electric wire 3 is formed in a predetermined shape (for example, a rectangular plate shape) using a water-impermeable material such as an insulating synthetic resin, and the opening 13 is also rectangular. The seal sheet 5 is penetrated in the thickness direction at the center of the seal sheet 5.
シールシート５は、電線３の長手方向の一端部に巻き付けつけられることで電線３に設けられており、芯線１１を覆っている。さらに説明すると、シールシート５は、この厚さ方向の両面もしくは片面に粘着剤もしくは接着剤の層が設けられており、芯線１１（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は離れた箇所（被覆体９の長手方向の一端よりも僅かに他端側の箇所）との間にわたって電線３に設けられている。これにより、芯線１１の長手方向では、被覆体９が除去されて露出している芯線１１の長さよりも、電線３に設置されているシールシート５の長さの方が長くなっている。
The seal sheet 5 is provided on the electric wire 3 by being wound around one end portion in the longitudinal direction of the electric wire 3 and covers the core wire 11. More specifically, the seal sheet 5 is provided with an adhesive or adhesive layer on both sides or one side in the thickness direction, and one end of the core wire 11 (electric wire 3) in the longitudinal direction, and from one end to the other end. It is provided in the electric wire 3 over the space | interval (location of the other end side slightly rather than the one end of the longitudinal direction of the covering body 9) only the predetermined distance toward the direction. Thereby, in the longitudinal direction of the core wire 11, the length of the seal sheet 5 installed in the electric wire 3 is longer than the length of the core wire 11 exposed by removing the covering 9.
このように、シールシート５が電線３に設置されている状態では、シールシート５に設けられている接着剤等の層により、シールシート５同士、シールシート５と芯線１１、シールシート５と被覆体９とがくっ付いており、また、シールシート５に開口部１３が形成されていないとすると、シールシート５は円筒状になっている。そして、円形状の底部１７が、芯線１１の長手方向の一端面に接して芯線１１の一端面を覆っており、円筒状の側板部１９が、芯線１１の長手方向の一端部と被覆体９の長手方向の一端部とを、芯線１１の外周および被覆体９の外周に接して覆っている。なお、電線３の被覆体９およびシールシート５は、可撓性（弾性）を備えている。また、シールシート５の円形状の底部１７は、シールシート５を寄り合わせてあるので、円板状部に加えて、中心に小さい突出部２１が形成されている。
Thus, in the state where the seal sheet 5 is installed on the electric wire 3, the seal sheet 5, the seal sheet 5 and the core wire 11, and the seal sheet 5 and the coating are covered by a layer such as an adhesive provided on the seal sheet 5. If the body 9 is attached and the opening 13 is not formed in the seal sheet 5, the seal sheet 5 is cylindrical. The circular bottom portion 17 is in contact with one end surface in the longitudinal direction of the core wire 11 to cover one end surface of the core wire 11, and the cylindrical side plate portion 19 is connected to the one end portion in the longitudinal direction of the core wire 11 and the covering 9. Is covered with the outer periphery of the core wire 11 and the outer periphery of the covering body 9. In addition, the covering body 9 and the seal sheet 5 of the electric wire 3 have flexibility (elasticity). Further, since the circular bottom portion 17 of the seal sheet 5 faces the seal sheet 5, a small protruding portion 21 is formed at the center in addition to the disk-shaped portion.
なお、粘着剤や接着剤を使用することなく、シールシート５自体が粘着性（貼り付き性）を備えたものであってもよい。
It should be noted that the seal sheet 5 itself may be provided with adhesiveness (adhesiveness) without using an adhesive or an adhesive.
ここで、シールシート５が電線３に設置されたときの、シールシート５の開口部１３について詳しく説明する。シールシート５の開口部１３は、電線３（芯線１１）の長手方向では、被覆体９が除去されて露出している芯線１１の中間部で所定の長さにわたって存在しており、電線３（芯線１１）の周方向では、芯線１１の１／３周程度の大きさになっている。シールシート５の開口部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。
Here, the opening 13 of the seal sheet 5 when the seal sheet 5 is installed on the electric wire 3 will be described in detail. In the longitudinal direction of the electric wire 3 (core wire 11), the opening 13 of the seal sheet 5 exists over a predetermined length at the intermediate portion of the core wire 11 that is exposed by removing the covering 9, and the electric wire 3 ( In the circumferential direction of the core wire 11), the size is about 1/3 of the core wire 11. It is desirable that the size of the opening 13 of the seal sheet 5 be a minimum that can ensure the electrical and mechanical performance of the terminal-attached electric wire 1.
端子７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７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 7 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 7 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の一端部の長さよりも長く、電線３に設置されたシールシート５の長さと同程度になっている。シールシート５が芯線１１に直接設置されている部位における板状の電線圧着部１５の幅の値は、芯線１１に直接設置されているシールシート５の外周の長さの値よりも僅かに大きくなっている。また、シールシート５が被覆体９に直接設置されている部位における板状の電線圧着部１５の幅の値は、被覆体９に直接設置されているシールシート５の外周の長さの値よりも僅かに大きくなっている。
The length of the wire crimping portion 15 is longer than the length of one end portion of the wire 3 and is about the same as the length of the seal sheet 5 installed on the wire 3. The value of the width of the plate-shaped electric wire crimping portion 15 at the portion where the seal sheet 5 is directly installed on the core wire 11 is slightly larger than the value of the outer circumference of the seal sheet 5 installed directly on the core wire 11. It has become. Further, the value of the width of the plate-shaped electric wire crimping portion 15 at the portion where the seal sheet 5 is directly installed on the cover body 9 is greater than the value of the outer circumference of the seal sheet 5 directly installed on the cover body 9. Is slightly larger.
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、電線圧着部１５にシールシート５が設置された電線３を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、シールシート５が設置されている電線３の一端部が押圧されて若干変形し電線圧着部１５で所定を押圧力をもって包み込まれ、電線３が端子７に一体的に設置されている。
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 seal sheet 5 is installed in the electric wire crimping part 15 and the electric wire crimping part 15 is crimped, so that the electric wire crimping part 15 becomes cylindrical and the electric wire 3 in which the seal sheet 5 is installed. One end of the wire is pressed and slightly deformed, and the wire crimping portion 15 wraps a predetermined amount with a pressing force, and the wire 3 is installed integrally with the terminal 7.
電線圧着部１５を電線３に圧着することにより電線３が端子７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おり、シールシート５の開口部１３を介して露出している芯線１１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の中央部に位置して電線圧着部１５に接触している。また、端子付き電線１では、電線３の長手方向の一端部（シールシート５が設置されている部位）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 electric wire with terminal 1 in which the electric wire 3 is integrally installed on the terminal 7 by crimping the electric wire crimping portion 15 to the electric wire 3, the protruding direction of the electric wire crimping portion 15 and the longitudinal direction of the electric wire 3 are the same. The core wire 11 exposed through the opening 13 of the seal sheet 5 is positioned in the center of the wire crimping portion 15 in the width direction of the wire crimping portion 15 (the circumferential direction of the wire 3). Are in contact with the wire crimping portion 15. Moreover, in the electric wire 1 with a terminal, the position of the one end part (site | part in which the seal sheet 5 is installed) of the longitudinal direction of the electric wire 3 and the position of the electric wire crimping part 15 correspond substantially mutually.
さらに、端子付き電線１では、電線３に設置されたシールシート５の開口部１３の周囲の部位が、開口部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、開口部１３等を通って、電線３の内部（芯線１１のところ）に水等が入り込まないようになっている。
Further, in the terminal-attached electric wire 1, the portion around the opening 13 of the seal sheet 5 installed in the electric wire 3 is in close contact with the electric wire crimping portion 15 over the entire circumference of the edge of the opening 13. Accordingly, water or the like is prevented from entering the inside of the electric wire 3 (at the core wire 11) from the outside of the electric wire 3 through the opening 13 or the like.
なお、上記説明では、電線３の長手方向の一端から他端に向かう方向で、電線３に設置されたシールシート５の開口部１３の一端が芯線１１の一端から他端側に僅かに離れているが、シールシート５の開口部１３の一端と芯線１１の一端とがお互いに一致していてもよい。
In the above description, one end of the opening 13 of the seal sheet 5 installed in the electric wire 3 is slightly separated from one end of the core wire 11 to the other end side in a direction from one end in the longitudinal direction of the electric wire 3 to the other end. However, one end of the opening 13 of the seal sheet 5 and one end of the core wire 11 may coincide with each other.
また、シールシート５を電線３に設置するときやシールシート５が設置された電線３を端子７に設置するとき、芯線１１に巻き付けられているシールシート５が若干延びて、シールシート５の開口部１３が大きくなることが想定されるので、電線３に設置される前のシールシート５の開口部１３は、小さめになっていることが望ましい。
Further, when the seal sheet 5 is installed on the electric wire 3 or when the electric wire 3 on which the seal sheet 5 is installed is installed on the terminal 7, the seal sheet 5 wound around the core wire 11 slightly extends and the opening of the seal sheet 5 is increased. Since it is assumed that the part 13 becomes large, it is desirable that the opening part 13 of the seal sheet 5 before being installed on the electric wire 3 is made smaller.
ここで、端子付き電線１の製造方法について説明する。
Here, the manufacturing method of the electric wire 1 with a terminal is demonstrated.
まず、図２に示すように、長手方向の一端部で被覆体９が除去された電線３と、開口部１３が設けられているシールシート５を用意する。
First, as shown in FIG. 2, the electric wire 3 from which the covering 9 is removed at one end in the longitudinal direction and the seal sheet 5 provided with the opening 13 are prepared.
続いて、シールシート５を電線３の長手方向の一端部に設置する。この状態で、電線３の長手方向の一端部が、シールシート５でシールされている。すなわち、開口部１３が非存在であるとすれば、電線３の長手方向の一端部で、電線３の外部から電線３の内部（芯線１１のことろ）に水等が入り込まないようになっている。
Subsequently, the seal sheet 5 is installed at one end of the electric wire 3 in the longitudinal direction. In this state, one end of the electric wire 3 in the longitudinal direction is sealed with the seal sheet 5. That is, if the opening 13 is absent, water or the like does not enter the inside of the electric wire 3 (the core wire 11) from the outside of the electric wire 3 at one end in the longitudinal direction of the electric wire 3. Yes.
続いて、シールシート５が設置された電線３の長手方向の一端部を、図４、５に示すように、端子７の電線圧着部１５のところに位置させる。
Subsequently, one end in the longitudinal direction of the electric wire 3 on which the seal sheet 5 is installed is positioned at the electric wire crimping portion 15 of the terminal 7 as shown in FIGS.
続いて、電線圧着部１５を電線３に圧着することで、図１で示すように、端子付き電線１が生成される。
Subsequently, by crimping the wire crimping portion 15 to the wire 3, the terminal-attached wire 1 is generated as shown in FIG. 1.
端子付き電線１によれば、電線３の芯線１１の一部が開口部１３を介して露出するようにシールシート５が電線３の一端部を覆っており、電線圧着部１５が電線３に圧着されることで、シールシート５の開口部１３を介して露出している芯線１１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１１の腐食を防止することができる。
According to the terminal-attached electric wire 1, the seal sheet 5 covers one end of the electric wire 3 so that a part of the core wire 11 of the electric wire 3 is exposed through the opening 13, and the electric wire crimping portion 15 is crimped to the electric wire 3. Thus, the core wire 11 exposed through the opening 13 of the seal sheet 5 comes into 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 11 can be prevented.
また、端子７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８（ａ）に示す圧着工程と図８（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７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 7 is installed on the electric wire 3, the two crimping steps (the crimping step shown in FIG. 8 (a) and the crimping step shown in FIG. 8 (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 7 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、図８（ｂ）で示す従来例の端子付き電線３０１のように、端子の電線圧着部を圧着して電線の長手方向の一端を包み込むことなく、電線３の一端部の芯線１１を、シールシート５によって覆っている。このため、芯線１１を確実にしかも容易にシールすることができる。
Moreover, according to the electric wire 1 with a terminal, the electric wire 3 without crimping the electric wire crimping portion of the terminal and wrapping one end in the longitudinal direction of the electric wire as in the conventional electric wire with a terminal 301 shown in FIG. The core wire 11 at one end is covered with a seal sheet 5. For this reason, the core wire 11 can be reliably and easily sealed.
また、端子付き電線１においては、図８（ｂ）で示す従来例の端子付き電線３０１のように、端子の電線圧着部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６で示すようにすることができる。
Moreover, in the electric wire 1 with a terminal, unlike the conventional electric wire 301 with a terminal shown in FIG. 8B, it is not necessary to crimp the electric wire crimping portion of the terminal and wrap one end in the longitudinal direction of the electric wire. For this reason, the form of the electric wire crimping | compression-bonding part 15 can be made to show in FIG.
すなわち、電線圧着部１５を、圧着本体部２５と、一対の基端側圧着部２７と、一対の先端側圧着部２９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 be configured to include a crimping main body portion 25, a pair of proximal-side crimping portions 27, and a pair of distal-end-side crimping portions 29.
電線３に圧着される前の電線圧着部１５では、図６で示すように、圧着本体部２５が半円柱側面状に形成されている。基端側圧着部２７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（箱状部２３側の部位）から突出している。先端側圧着部２９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（箱状部２３とは反対側の部位）から突出している。
In the wire crimping part 15 before being crimped to the electric wire 3, as shown in FIG. 6, the crimping main body part 25 is formed in a semi-cylindrical side surface shape. The base end side crimping portion 27 is formed in a flat plate shape and protrudes from a base end side portion (a portion on the box-like portion 23 side) of the wire crimping portion 15. The distal end side crimping portion 29 is also formed in a flat plate shape, and protrudes from the distal end side portion of the electric wire crimping portion 15 (the portion opposite to the box-like portion 23).
電線圧着部１５を電線３に圧着した状態では、基端側圧着部２７が電線３の長手方向でシールシートの開口部１３よりも一端側に位置している部位３１（図３（ｂ）参照）に係合しており、先端側圧着部２９が電線３の長手方向でシールシートの開口部１３よりも他端側に位置している部位３３（図３（ｂ）参照）に係合している。
In a state where the wire crimping portion 15 is crimped to the wire 3, a portion 31 (see FIG. 3B) where the proximal end side crimping portion 27 is located on one end side with respect to the opening portion 13 of the seal sheet in the longitudinal direction of the wire 3. ), And the distal end side crimping portion 29 is engaged with a portion 33 (see FIG. 3B) located on the other end side of the opening portion 13 of the seal sheet in the longitudinal direction of the electric wire 3. ing.
端子７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２５と一対の基端側圧着部２７と一対の先端側圧着部２９とを備える。このため、端子７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 7, the electric wire crimping portion 15 includes the crimping main body portion 25, a pair of proximal-side crimping portions 27, and a pair of distal-end-side crimping portions 29. For this reason, it becomes easy to adjust the crimping | compression condition of the electric wire 3 in the terminal 7. 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.
なお、図２（ａ）の二点鎖線Ｌ１の内側の部分を削除して、シールシート５の開口部１３をＵ字状の切り欠きにしてもよい。
In addition, you may delete the inner part of the dashed-two dotted line L1 of Fig.2 (a), and you may make the opening part 13 of the seal sheet 5 into a U-shaped notch.
この場合、シールシート５の寸法Ｂ１を増やし、電線３の長手方向の一端部にシールシート５を設置したとき、寸法Ｂ１の端側の部位が、寸法Ｂ２で示す部位に重なるようにすることが望ましい。
In this case, when the dimension B1 of the seal sheet 5 is increased and the seal sheet 5 is installed at one end in the longitudinal direction of the electric wire 3, the part on the end side of the dimension B1 may overlap the part indicated by the dimension B2. desirable.
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.
