つまり、芯線Ba全長側に外囲された残りの被覆材Bbから切り離された被覆材Bcの不要な部分が、芯線Ba端部より所望する寸法だけ突出され、被覆材Bcの必要な部分が芯線Ba端部に残される切残し位置(図2参照)と、電線B端部に外囲した被覆材Bbが所望する寸法だけ切除される切込み位置(図1参照)と、芯線Ba端部より突出する被覆材Bcが該芯線Ba端面に沿って切除される切込み位置(図3参照)へ移動される。   That is, an unnecessary portion of the covering material Bc cut off from the remaining covering material Bb surrounded on the entire length side of the core wire Ba protrudes from the end of the core wire Ba by a desired dimension, and a necessary portion of the covering material Bc is the core wire. The uncut position (refer to FIG. 2) left at the Ba end, the cut position (see FIG. 1) where the covering material Bb surrounded by the end of the electric wire B is cut by a desired dimension, and the core Ba protrude from the end. The covering material Bc to be moved is moved to a cutting position (see FIG. 3) cut along the end face of the core wire Ba.

なお、一対の各刃物3,3は移動せず、一対の各挟持体2,2で挟持した電線B側を、刃物3の切込み位置よりも芯線Ba端部側に外囲した被覆材Bcが、芯線Ba全長側に外囲された残りの被覆材Bbから切り離される方向へ移動してもよい。   Note that the pair of blades 3 and 3 do not move, and the covering material Bc that surrounds the wire B side sandwiched between the pair of sandwiching bodies 2 and 2 closer to the end of the core wire Ba than the cutting position of the blade 3 is provided. The core wire Ba may be moved in the direction of being separated from the remaining covering material Bb surrounded by the entire length of the core wire Ba.

前記端子接続構造体である電線B端部に圧着端子Aを取り付ける際の端子接続方法を説明する。   The terminal connection method at the time of attaching the crimp terminal A to the electric wire B end part which is the said terminal connection structure is demonstrated.

先ず、図1に示すように、一対の各挟持体2,2により電線B全長側を挟持した後、一対の各刃物3,3を閉位置へ移動して、電線B端部に外囲した被覆材Bbに対して径方向へ切り込ませるとともに、電線B中心に挿入された芯線Baには切り込まず、被覆材Bbのみに切り込みを入れる。   First, as shown in FIG. 1, after the electric wire B full length side is pinched by a pair of holding members 2 and 2, the pair of blades 3 and 3 are moved to the closed position and surrounded by the ends of the electric wire B. The coating material Bb is cut in the radial direction, and is not cut into the core wire Ba inserted in the center of the electric wire B, but only the coating material Bb is cut.

次に、図2に示すように、各刃物3,3を電線B端部に外囲した被覆材Bbに切り込ませたまま、刃物3の切込み位置よりも芯線Ba端部側に外囲した被覆材Bcが、芯線Ba全長側に外囲された残りの被覆材Bbから切り離される矢印方向(図2中の右側)へ電線Bの長さ方向に沿って一定量移動させるとともに、電線B端部の被覆材Bbより突出する芯線Baを、圧着端子AのワイヤーバレルAcが圧着される面積だけ露出する。   Next, as shown in FIG. 2, each blade 3, 3 is surrounded by the core wire Ba end side from the cutting position of the blade 3 while being cut into the covering material Bb surrounded by the end portion of the electric wire B. The covering material Bc is moved by a certain amount along the length direction of the electric wire B in the direction of the arrow (the right side in FIG. 2) separated from the remaining covering material Bb surrounded by the entire length of the core wire Ba, and the end of the electric wire B The core wire Ba protruding from the covering material Bb of the portion is exposed by the area where the wire barrel Ac of the crimp terminal A is crimped.

芯線Ba全長側に外囲された残りの被覆材Bbから切り離された被覆材Bcを、被覆材Bcの不要な部分が芯線Ba端部より突出され、被覆材Bcの必要な部分が芯線Ba端部に残されるセミストリップ位置へ移動した後、図3に示すように、各刃物3,3を開位置へ移動して、芯線Ba端部に移動された被覆材Bcに対して接触及び当接が回避される間隔に離間したまま、芯線Ba端部より突出する被覆材Bcの不要な部分に対して芯線Ba端面に沿って切り込まれる位置へC距離だけ移動させる。   The coating material Bc cut off from the remaining coating material Bb surrounded on the entire length side of the core wire Ba is formed such that an unnecessary portion of the coating material Bc is protruded from the end portion of the core wire Ba, and a necessary portion of the coating material Bc is the end of the core wire Ba. After moving to the semi-strip position remaining in the part, as shown in FIG. 3, each cutter 3, 3 is moved to the open position, and comes into contact and contact with the covering material Bc moved to the end of the core wire Ba. While being separated at an interval to avoid the above, an unnecessary portion of the covering material Bc protruding from the end portion of the core wire Ba is moved by a C distance to a position cut along the end surface of the core wire Ba.

次に、図4に示すように、一対の各刃物3,3を、芯線Ba端面に沿って該芯線Ba端部に外囲した被覆材Bcに対して径方向へ切り込ませて、芯線Ba端部より突出する被覆材Bcの不要な部分を該芯線Ba端面に沿って切除するので、必要な部分の被覆材Bcを、芯線Ba端部が外囲されるセミストリップ状態に残すことができる。   Next, as shown in FIG. 4, the pair of blades 3 and 3 are cut in the radial direction along the end face of the core wire Ba with respect to the covering material Bc surrounded by the end portion of the core wire Ba. Since an unnecessary portion of the covering material Bc protruding from the end portion is cut along the end surface of the core wire Ba, the necessary portion of the covering material Bc can be left in a semi-strip state in which the end portion of the core wire Ba is surrounded. .

芯線Ba端部に残されたセミストリップ状態の被覆材Bcにより、電線B端部の被覆材Bbより突出する複数本の各芯線Ba…を一つに束ねられた状態に拘束することができるので、電線B端部に圧着端子Aを取り付ける際に、電線B端部の被覆材Bbより突出する各芯線Ba…が外側へ広がったり、一部の芯線Baが圧着端子Aの外側へ突出(芯線こぼれ)するのを防止することができ、電線Bの各芯線Ba…と圧着端子Aを適切な状態に接続することができる。   Since the semi-strip state covering material Bc left at the end of the core wire Ba can restrain the plurality of core wires Ba ... protruding from the covering material Bb at the end of the electric wire B to be bundled together. When attaching the crimp terminal A to the end of the electric wire B, each core wire Ba projecting from the covering material Bb at the end of the electric wire B spreads outward, or a part of the core wire Ba protrudes to the outside of the crimp terminal A (core wire Spills), and the core wires Ba of the electric wires B and the crimp terminals A can be connected in an appropriate state.

この後、各刃物3,3を開位置へ移動させ、次の電線B端部に外囲した被覆材Bbに対して切り込まれる初期位置に復帰移動する。また、各挟持体2,2を開位置へ移動させ、各挟持体2,2による電線Bの挟持を解除すれば、複数本の各芯線Ba…を一つに束ねられた状態に拘束する作業が完了する。   Thereafter, each of the blades 3 and 3 is moved to the open position, and returned to the initial position where it is cut into the covering material Bb surrounded by the end of the next electric wire B. Moreover, if each clamping body 2 and 2 is moved to an open position and clamping of the electric wire B by each clamping body 2 and 2 is cancelled | released, the operation | work which restrains each core wire Ba ... in the state bundled together in one Is completed.

次に、各挟持体2,2間から抜き取ったセミストリップ済みの電線Bを圧着工程へ供給するとともに、図5、図6に示すように、被覆材Bcを芯線Ba端部が束ねられる位置に残したセミストリップ状態にて、電線B端部に圧着端子Aを圧着接続すれば、圧着接続時において、電線Bの芯線Baが圧着端子Aよりも外側へ突出するか、他の部材に干渉するのを防止することができる。   Next, the semi-striped electric wire B extracted from between the sandwiching bodies 2 and 2 is supplied to the crimping process, and the covering material Bc is placed at a position where the end portion of the core wire Ba is bundled as shown in FIGS. If the crimping terminal A is crimped and connected to the end of the electric wire B in the remaining semi-strip state, the core wire Ba of the electric wire B protrudes outside the crimping terminal A or interferes with other members at the time of crimping connection. Can be prevented.

また、圧着端子Aのバレル部Aaに形成したインシュレーションバレルAbは、芯線Ba全長側に外囲された残りの被覆材Bbに圧着して加締め固定され、ワイヤーバレルAcは、芯線Ba全長側に外囲された残りの被覆材Bbと、芯線Ba端部に外囲した被覆材Bcの間に露出する芯線Baに圧着して加締め固定される。   The insulation barrel Ab formed on the barrel portion Aa of the crimp terminal A is crimped and fixed to the remaining covering material Bb surrounded on the entire length of the core wire Ba, and the wire barrel Ac is connected to the entire length of the core wire Ba. Are crimped and fixed to the core wire Ba exposed between the remaining coating material Bb surrounded by and the coating material Bc surrounded by the end portion of the core wire Ba.

図7〜図9は、電線Bの端子接続方法の他の例を示し、一対の各刃物3,3を、電線B端部に外囲した被覆材Bbに切り込ませて、被覆材Bbのみに切り込みを入れた後(図1参照)、各刃物3,3を電線B端部に外囲した被覆材Bbに切り込ませたまま、刃物3の切込み位置よりも芯線Ba端部側に外囲した被覆材Bcが、該芯線Baに外囲された残りの被覆材Bbから切り離される方向へ移動させ、残りの被覆材Bbから切り離された被覆材Bcを芯線Ba端部から抜き取る(図7参照)。   FIGS. 7-9 shows the other example of the terminal connection method of the electric wire B, cuts a pair of each blade 3 and 3 in the coating | covering material Bb enclosed by the electric wire B edge part, and only the coating | coated material Bb. (See FIG. 1), the blades 3 and 3 are cut into the covering material Bb surrounded by the ends of the electric wires B, and the outer ends of the blades 3 are moved outward from the cutting positions of the blades 3. The enclosed coating material Bc is moved in a direction to be separated from the remaining coating material Bb surrounded by the core wire Ba, and the coating material Bc separated from the remaining coating material Bb is extracted from the end of the core wire Ba (FIG. 7). reference).

次に、各刃物3,3を開位置へ移動して、芯線Ba全長側に外囲した被覆材Bbに対して接触及び当接が回避される間隔に離間したまま、芯線Ba全長側に外囲した被覆材Bb端部に対して切り込まれる位置へC距離だけ移動させる(図8参照)。   Next, each of the blades 3 and 3 is moved to the open position, and the blades 3 and 3 are moved outward to the full length of the core wire Ba while being spaced apart from each other so as to avoid contact and contact with the covering material Bb surrounded on the full length side of the core wire Ba. It moves only C distance to the position cut with respect to the surrounding coating | covering material Bb edge part (refer FIG. 8).

次に、各刃物3,3を、芯線Ba全長側に外囲した被覆材Bbに切り込ませたまま、刃物3の切込み位置よりも芯線Ba端部側に外囲した被覆材Bcが、該芯線Ba全長側に外囲された残りの被覆材Bbから切り離される方向へ移動するとともに、残りの被覆材Bb端部より突出する芯線Baを、圧着端子AのワイヤーバレルAcが圧着される面積だけ露出する(図9参照)。   Next, with the blades 3 and 3 being cut into the covering material Bb surrounded on the entire length side of the core wire Ba, the covering material Bc surrounded on the end side of the core wire Ba from the cutting position of the blade 3 is The core wire Ba moves in a direction to be cut off from the remaining covering material Bb surrounded by the entire length of the core wire Ba, and the core wire Ba protruding from the end of the remaining covering material Bb is only the area where the wire barrel Ac of the crimp terminal A is crimped. Exposed (see FIG. 9).

つまり、芯線Ba全長側の被覆材Bbから切り離されたリング状の被覆材Bcを、芯線Ba端部が外囲されるセミストリップ位置へ移動させて、複数本の各芯線Ba…を一つに束ねられた状態に拘束するので、電線B端部に圧着端子Aを取り付ける作業途中において、各芯線Ba…が外側へ広がったり、一部の芯線Baが圧着端子Aの外側へ突出するのを防止することができる。また、被覆材Bcを芯線Ba端部に残したセミストリップ状態にて、電線B端部に圧着端子Aを圧着接続(図5、図6参照)するので、前記実施例と略同等の作用及び効果を奏することができる。   That is, the ring-shaped coating material Bc cut off from the coating material Bb on the entire length side of the core wire Ba is moved to the semi-strip position where the end of the core wire Ba is surrounded, so that the plurality of core wires Ba. Since it is constrained to a bundled state, it is possible to prevent each core wire Ba from spreading outward or protruding a part of the core wire Ba to the outside of the crimp terminal A during the operation of attaching the crimp terminal A to the end of the electric wire B. can do. Further, since the crimp terminal A is crimped and connected to the end of the electric wire B (see FIGS. 5 and 6) in a semi-strip state in which the covering material Bc is left at the end of the core wire Ba, There is an effect.

図10は、電線Bの芯線Ba上に残されたセミストリップ状態の被覆材Bcを、圧着端子Aのバレル部Aa内壁面に突出した一対の各突起Ae,Aeで抜止めする抜止め方法を示している。つまり、電線B端部に圧着端子Aを圧着接続した際に、被覆材Bcが芯線Ba端部から抜け落ちる方向(長さ方向)へ移動しようとしても、セミストリップ状態の被覆材Bcよりも先端側に形成した各突起Ae,Aeに当接して抜止めされるので、電線B端部の被覆材Bbより突出する複数本の各芯線Ba…を一つに束ねられた状態に維持することができる。なお、突起Aeの突出量は、少なくとも被覆材Bcが芯線Ba端部から抜けようとする際に突き当たる程度の突出量が好ましい。また、芯線Baと突起Aeの間隔aは、被覆材Bcの全長bよりも短いものとする。   FIG. 10 shows a method of retaining the semi-strip coating material Bc remaining on the core wire Ba of the electric wire B with a pair of protrusions Ae and Ae protruding on the inner wall surface of the barrel portion Aa of the crimp terminal A. Show. That is, when the crimp terminal A is crimped and connected to the end portion of the electric wire B, even if the coating material Bc tries to move in the direction (length direction) that falls off from the end portion of the core wire Ba, the tip side of the semi-strip coating material Bc Since each of the projections Ae, Ae is formed in contact with each other and is prevented from being pulled out, a plurality of core wires Ba projecting from the covering material Bb at the end of the electric wire B can be maintained in a bundled state. . In addition, the protrusion amount of the protrusion Ae is preferably an amount of protrusion that at least hits when the coating material Bc tries to come out from the end portion of the core wire Ba. The interval a between the core wire Ba and the protrusion Ae is shorter than the total length b of the covering material Bc.

図11は、電線Bの芯線Baを、芯線Ba上に残されたセミストリップ状態の被覆材Bcごと圧着端子Aのバレル部Aaに形成したセミインシュレーションバレルAdで圧着して加締め固定する他の抜止め方法を示している。つまり、電線B端部に圧着端子Aを圧着接続した際に、被覆材Bcの位置が変位するか、被覆材Bcが芯線Ba端部から抜け落ちるのを防止することができ、電線B端部の被覆材Bbより突出する複数本の各芯線Ba…を一つに束ねられた状態に維持することができる。なお、バレル部Aaに形成したインシュレーションバレルAbは、芯線Baに外囲された残りの被覆材Bbに圧着して加締め固定される。また、ワイヤーバレルAcは、芯線Baに外囲された残りの被覆材Bbと、芯線Ba端部に外囲した被覆材Bcの間に露出する芯線Baに圧着して加締め固定される。   FIG. 11 shows a method of crimping and fixing the core wire Ba of the electric wire B with the semi-insulation barrel Ad formed on the barrel portion Aa of the crimp terminal A together with the semi-strip state coating material Bc remaining on the core wire Ba. This shows how to prevent the removal. That is, when the crimp terminal A is crimped and connected to the end portion of the electric wire B, the position of the covering material Bc is displaced or the covering material Bc can be prevented from falling off from the end portion of the core wire Ba. A plurality of core wires Ba... Protruding from the covering material Bb can be maintained in a bundled state. The insulation barrel Ab formed in the barrel portion Aa is crimped and fixed to the remaining coating material Bb surrounded by the core wire Ba. The wire barrel Ac is crimped and fixed to the core wire Ba exposed between the remaining coating material Bb surrounded by the core wire Ba and the coating material Bc surrounded by the end of the core wire Ba.

図12は、電線Bの芯線Ba上に残されたセミストリップ状態の被覆材Bcよりも、該被覆材Bcのさらに先端側に突出する芯線Baを圧着端子Aのバレル部Aaに形成したワイヤーバレルAcで圧着して加締め固定するその他の抜止め方法を示している。つまり、被覆材Bcが芯線Ba端部から抜け落ちる方向へ移動しようとしても、被覆材B先端側の芯線Baに圧着されたバレル部AaのワイヤーバレルAcに当接して抜止めされるので、電線B端部の被覆材Bbより突出する複数本の各芯線Ba…を一つに束ねられた状態に維持することができる。
また、ワイヤーバレルAcを2箇所設けたことで、電線Bと圧着端子Aの間の電気的接続の安定性が向上するので好ましい。 Further, it is preferable to provide the wire barrel Ac at two places because the stability of the electrical connection between the electric wire B and the crimp terminal A is improved. 尚、インシュレーションバレルAbは省略することも可能である。 The insulation barrel Ab can be omitted. FIG. 12 shows a wire barrel in which a core wire Ba that protrudes further toward the distal end side of the covering material Bc is formed on the barrel portion Aa of the crimp terminal A than the semi-strip state covering material Bc left on the core wire Ba of the electric wire B The other retaining method of crimping and fixing by Ac is shown. That is, even if the covering material Bc tries to move away from the end of the core wire Ba, the covering material Bc comes into contact with the wire barrel Ac of the barrel portion Aa that is crimped to the core wire Ba on the front end side of the covering material B. A plurality of core wires Ba projecting from the covering material Bb at the end can be maintained in a bundled state. FIG. 12 shows a wire barrel in which a core wire Ba that protrudes further toward the distal end side of the covering material Bc is formed on the barrel portion Aa of the crimp terminal A than the semi-strip state covering material Bc left on the core wire Ba of the electric wire B The other retaining method of crimping and fixing by Ac is shown. That is, even if the covering material Bc tries to move away from the end of the core wire Ba, the covering material Bc comes into contact. with the wire barrel Ac of the barrel portion Aa that is crimped to the core wire Ba on the front end side of the covering material B. A plurality of core wires Ba projecting from the covering material Bb at the end can be maintained in a bundled state.
In addition, providing two wire barrels Ac is preferable because the stability of electrical connection between the electric wire B and the crimp terminal A is improved. The insulation barrel Ab can be omitted. In addition, providing two wire barrels Ac is preferred because the stability of electrical connection between the electric wire B and the crimp terminal A is improved.
