Description

本発明は、端子金具、端子金具付き電線、及び端子金具付き電線の製造方法に関する。   The present invention relates to a terminal fitting, an electric wire with a terminal fitting, and a method for manufacturing an electric wire with a terminal fitting.

従来より、電線の端部に圧着される端子金具としては特許文献１に記載のものが知られている。この端子金具は、電線の端部から露出する芯線に圧着される圧着部と、この圧着部から延びて相手側端子金具と接続する接続部と、を備える。芯線に圧着部が圧着されることで、芯線と圧着部とが電気的に接続される。
特開平１０−１２５３６２公報 Conventionally, what is described in Patent Document 1 is known as a terminal fitting to be crimped to an end of an electric wire. The terminal fitting includes a crimping portion that is crimped to the core wire exposed from the end of the electric wire, and a connection portion that extends from the crimping portion and is connected to the mating terminal fitting. By crimping the crimping portion to the core wire, the core wire and the crimping portion are electrically connected.
Japanese Patent Laid-Open No. 10-125362

上記の芯線の表面に酸化膜が形成されると、電線と端子金具との電気抵抗が増大することが懸念される。この問題を解決するために、芯線に圧着部を圧着する際の圧力を大きくすることが考えられる。これにより、芯線が圧着部から圧力を受けて大きく塑性変形し、芯線の表面と圧着部の内壁とが摺接する。すると、芯線の表面に形成された酸化膜が剥がれて芯線の新生面が露出する。この新生面と、圧着部とが接触することにより電線と端子金具との電気抵抗が低減することが期待された。   If an oxide film is formed on the surface of the core wire, there is a concern that the electrical resistance between the electric wire and the terminal fitting increases. In order to solve this problem, it is conceivable to increase the pressure when the crimping part is crimped to the core wire. As a result, the core wire is greatly plastically deformed by receiving pressure from the crimping portion, and the surface of the core wire and the inner wall of the crimping portion are in sliding contact. Then, the oxide film formed on the surface of the core wire is peeled off and the new surface of the core wire is exposed. It was expected that the electrical resistance between the electric wire and the terminal fitting would be reduced by the contact between the new surface and the crimping part.

しかしながら、上記の構成によると、圧着部に比較的に大きな圧力を加えることにより、圧着部自身が塑性変形し、端子金具の長さ寸法が大きくなってしまうという問題がある。特に、電線の延びる方向についての端子金具の長さ寸法が大きく変化すると、端子金具をコネクタハウジング内に収容する際に、端子金具がコネクタハウジングからはみ出してしまう等の問題が懸念される。   However, according to the above configuration, there is a problem in that, by applying a relatively large pressure to the crimping portion, the crimping portion itself is plastically deformed, and the length dimension of the terminal fitting is increased. In particular, if the length of the terminal fitting in the direction in which the electric wire extends greatly changes, there is a concern that the terminal fitting protrudes from the connector housing when the terminal fitting is accommodated in the connector housing.

本発明は上記のような事情に基づいて完成されたものであって、圧着の前後において、電線の延びる方向について長さ寸法が大きくなることが抑制された端子金具、端子金具付き電線、及び端子金具付き電線の製造方法を提供することを目的とする。   This invention was completed based on the above situations, Comprising: Before and after crimping | compression-bonding, the terminal metal fitting with which the length dimension was suppressed about the extension direction of an electric wire, the electric wire with a terminal metal fitting, and a terminal It aims at providing the manufacturing method of an electric wire with a metal fitting.

本発明は、芯線を含む電線と、前記芯線が載置される底板の側縁から側方に突出すると共に前記芯線に巻き付くように圧着されるバレル片を有する端子金具と、を備えた端子金具付き電線の製造方法であって、前記底板のうち前記芯線が載置される面と反対側の面に、前記電線の延びる方向に間隔を開けて複数の凸部を形成する工程と、前記底板の凸部に対応する位置に凹部が形成されたアンビルに、前記アンビルの凹部内に前記底板の凸部を挿入させつつ前記底板を載置する工程と、前記底板に前記芯線が載置された状態で、前記アンビルの上方からクリンパを前記アンビルに接近させるように相対移動させて、前記クリンパによって前記バレル片を押圧することで前記バレル片を前記芯線に巻き付けるように圧着する工程と、を実行することを特徴とする。   The present invention is a terminal comprising: an electric wire including a core wire; and a terminal fitting having a barrel piece that protrudes laterally from a side edge of a bottom plate on which the core wire is placed and is crimped so as to be wound around the core wire. A method of manufacturing an electric wire with a metal fitting, the step of forming a plurality of convex portions on the surface of the bottom plate opposite to the surface on which the core wire is placed, with an interval in the extending direction of the electric wire, Placing the bottom plate while inserting the convex portion of the bottom plate into the concave portion of the anvil on the anvil having a concave portion formed at a position corresponding to the convex portion of the bottom plate; and placing the core wire on the bottom plate. In a state where the crimper is relatively moved so as to approach the anvil from above the anvil, and the barrel piece is pressed by the crimper so as to be wound around the core wire. Run And wherein the door.

また、本発明は、芯線を含む電線と、前記芯線に圧着される端子金具と、を備えた端子金具付き電線であって、前記端子金具は、前記芯線が載置される底板と、前記芯線が載置される底板の側縁から側方に突出すると共に前記芯線に巻き付くように圧着されるバレル片と、前記底板から延びて相手側端子と接続する接続部と、を備え、前記バレル片は、アンビルと、前記アンビルの上方に配されるクリンパとの間に挟まれることによって前記芯線に圧着されるようになっており、前記底板のうち前記芯線が載置される面と反対側の面には、前記電線の延びる方向に間隔を開けて形成されると共に、前記アンビルに形成された凹部内に挿入される複数の凸部が形成されていることを特徴とする。   Moreover, this invention is an electric wire with a terminal metal fitting provided with the electric wire containing a core wire, and the terminal metal fitting crimped | bonded to the said core wire, Comprising: The said terminal metal fitting is a baseplate in which the said core wire is mounted, The said core wire A barrel piece that protrudes laterally from a side edge of the bottom plate on which is placed and is pressure-bonded so as to be wound around the core wire, and a connecting portion that extends from the bottom plate and connects to a mating terminal. The piece is sandwiched between an anvil and a crimper disposed above the anvil so as to be crimped to the core wire, and the side of the bottom plate opposite to the surface on which the core wire is placed The surface is formed with a plurality of protrusions inserted into the recesses formed in the anvil while being formed at intervals in the extending direction of the electric wires.

また、本発明は、芯線を含む電線から露出する前記芯線が載置される底板と、前記芯線が載置される底板の側縁から側方に突出すると共に前記電線に巻き付くように圧着されるバレル片と、前記底板から延びて相手側端子と接続する接続部と、を備えた端子金具であって、前記バレル片は、アンビルと、前記アンビルの上方に配されるクリンパとの間に挟まれることによって前記芯線に圧着されるようになっており、前記底板のうち前記芯線が載置される面と反対側の面には、前記電線の延びる方向に間隔を開けて形成されると共に、前記アンビルに形成された凹部内に挿入される複数の凸部が形成されていることを特徴とする。   The present invention also includes a bottom plate on which the core wire exposed from the electric wire including the core wire is placed, and a side plate protruding from the side edge of the bottom plate on which the core wire is placed, and is crimped so as to be wound around the electric wire. A barrel piece and a connection fitting extending from the bottom plate and connected to a mating terminal, wherein the barrel piece is between an anvil and a crimper disposed above the anvil. It is adapted to be crimped to the core wire by being sandwiched, and formed on the surface of the bottom plate opposite to the surface on which the core wire is placed with a gap in the direction in which the electric wire extends. A plurality of convex portions to be inserted into the concave portions formed in the anvil are formed.

本発明によれば、バレル片を芯線に圧着する際に、バレル片がクリンパとアンビルとに挟まれることで、バレル片には圧力が加わる。バレル片に加えられた圧力は芯線を介して底板に伝達される。底板に圧力が伝達されることにより、底板は電線の延びる方向に伸びようとする。しかしながら、底板に形成された凸部は、アンビルに形成された凹部内に挿入されているので、凸部の外側面が凹部の内側面と当接する。この結果、凸部が電線の延びる方向について変位することが凹部によって抑制されるので、底板が電線の延びる方向について伸びることを抑制できる。   According to the present invention, when the barrel piece is crimped to the core wire, the barrel piece is sandwiched between the crimper and the anvil, so that pressure is applied to the barrel piece. The pressure applied to the barrel piece is transmitted to the bottom plate via the core wire. When the pressure is transmitted to the bottom plate, the bottom plate tends to extend in the direction in which the electric wire extends. However, since the convex part formed in the bottom plate is inserted into the concave part formed in the anvil, the outer surface of the convex part comes into contact with the inner side surface of the concave part. As a result, the convex portion is suppressed from being displaced in the extending direction of the electric wire by the concave portion, so that the bottom plate can be suppressed from extending in the extending direction of the electric wire.

また、本発明は、芯線を含む電線と、前記芯線が載置される底板の側縁から側方に突出すると共に前記芯線に巻き付くように圧着されるバレル片を有する端子金具と、を備えた端子金具付き電線の製造方法であって、前記底板のうち前記芯線が載置される面と反対側の面に、前記電線の延びる方向に間隔を開けて複数の凹部を形成する工程と、前記底板の凹部に対応する位置に凸部が形成されたアンビルに、前記底板の凹部内に前記アンビルの凸部を挿入させつつ前記底板を載置する工程と、前記底板に前記芯線が載置された状態で、前記アンビルの上方からクリンパを前記アンビルに接近させるように相対移動させて、前記クリンパによって前記バレル片を押圧することで前記バレル片を前記芯線に巻き付けるように圧着する工程と、を実行することを特徴とする。   The present invention also includes an electric wire including a core wire, and a terminal fitting having a barrel piece that protrudes laterally from a side edge of a bottom plate on which the core wire is placed and is crimped to wrap around the core wire. A method of manufacturing an electric wire with a terminal fitting, the step of forming a plurality of recesses on the surface of the bottom plate opposite to the surface on which the core wire is placed, with an interval in the extending direction of the electric wire, Placing the bottom plate on the anvil having a convex portion formed at a position corresponding to the concave portion of the bottom plate while inserting the convex portion of the anvil into the concave portion of the bottom plate; and placing the core wire on the bottom plate In such a state, a crimping is performed so that the barrel piece is wound around the core wire by relatively moving the crimper from above the anvil so as to approach the anvil and pressing the barrel piece by the crimper. The fruit Characterized in that it.

また、本発明は、芯線を含む電線と、前記芯線に圧着される端子金具と、を備えた端子金具付き電線であって、前記端子金具は、前記芯線が載置される底板と、前記芯線が載置される底板の側縁から側方に突出すると共に前記芯線に巻き付くように圧着されるバレル片と、前記底板から延びて相手側端子と接続する接続部と、を備え、前記バレル片は、アンビルと、前記アンビルの上方に配されるクリンパとの間に挟まれることによって前記芯線に圧着されるようになっており、前記底板のうち前記芯線が載置される面と反対側の面には、前記電線の延びる方向に間隔を開けて形成されると共に、前記アンビルに形成された凸部が挿入される複数の凹部が形成されていることを特徴とする。   Moreover, this invention is an electric wire with a terminal metal fitting provided with the electric wire containing a core wire, and the terminal metal fitting crimped | bonded to the said core wire, Comprising: The said terminal metal fitting is a bottom plate in which the said core wire is mounted, The said core wire A barrel piece that protrudes laterally from a side edge of the bottom plate on which is placed and is pressure-bonded so as to be wound around the core wire, and a connecting portion that extends from the bottom plate and connects to a mating terminal. The piece is sandwiched between an anvil and a crimper disposed above the anvil so as to be crimped to the core wire, and the side of the bottom plate opposite to the surface on which the core wire is placed The surface is formed with a plurality of concave portions into which the convex portions formed in the anvil are inserted, and is formed at intervals in the extending direction of the electric wires.

また、本発明は、芯線を含む電線から露出する前記芯線が載置される底板と、前記芯線が載置される底板の側縁から側方に突出すると共に前記電線に巻き付くように圧着されるバレル片と、前記底板から延びて相手側端子と接続する接続部と、を備え端子金具であって、前記バレル片は、アンビルと、前記アンビルの上方に配されるクリンパとの間に挟まれることによって前記芯線に圧着されるようになっており、前記底板のうち前記芯線が載置される面と反対側の面には、前記電線の延びる方向に間隔を開けて形成されると共に、前記アンビルに形成された凸部が挿入される複数の凹部が形成されていることを特徴とする。   The present invention also includes a bottom plate on which the core wire exposed from the electric wire including the core wire is placed, and a side plate protruding from the side edge of the bottom plate on which the core wire is placed, and is crimped so as to be wound around the electric wire. A barrel piece and a connection portion extending from the bottom plate and connected to a mating terminal, wherein the barrel piece is sandwiched between an anvil and a crimper disposed above the anvil. Is formed so as to be crimped to the core wire, and is formed on the surface of the bottom plate opposite to the surface on which the core wire is placed with a gap in the extending direction of the electric wire, A plurality of concave portions into which convex portions formed on the anvil are inserted are formed.

本発明によれば、バレル片を芯線に圧着する際に、バレル片がクリンパとアンビルとに挟まれることで、バレル片には圧力が加わる。バレル片に加えられた圧力は芯線を介して底板に伝達される。底板に圧力が伝達されることにより、底板は電線の延びる方向に伸びようとする。しかしながら、アンビルに形成された凸部は、底板に形成された凹部内に嵌入しているので、凹部の内側面が凸部の外側面と当接する。この結果、凹部が電線の延びる方向に沿って変位することが抑制されるので、底板が電線の延びる方向について伸びることを抑制できる。   According to the present invention, when the barrel piece is crimped to the core wire, the barrel piece is sandwiched between the crimper and the anvil, so that pressure is applied to the barrel piece. The pressure applied to the barrel piece is transmitted to the bottom plate via the core wire. When the pressure is transmitted to the bottom plate, the bottom plate tends to extend in the direction in which the electric wire extends. However, since the convex part formed in the anvil is fitted in the concave part formed in the bottom plate, the inner side surface of the concave part comes into contact with the outer side surface of the convex part. As a result, since the concave portion is suppressed from being displaced along the direction in which the electric wire extends, it is possible to suppress the bottom plate from extending in the direction in which the electric wire extends.

なお、凹部は、底板のうち接触面の反対側の面にくぼんだ形状が形成されていればよく、底板を貫通する貫通孔を含む。   In addition, the recessed part should just be formed in the hollow shape in the surface on the opposite side to a contact surface among bottom plates, and contains the through-hole which penetrates a bottom plate.

本発明の実施態様としては以下の態様が好ましい。
前記底板に、前記バレル片が形成された領域よりも前記電線の延びる方向について外方の位置に前記凸部を形成されていてもよい。 As embodiments of the present invention, the following embodiments are preferable.
The convex portion may be formed on the bottom plate at an outer position in a direction in which the electric wire extends than an area where the barrel piece is formed.

上記の態様によれば、底板のうちバレル片が形成された領域が電線の延びる方向に伸びるのを、確実に抑制できる。   According to said aspect, it can suppress reliably that the area | region in which the barrel piece was formed among baseplates extends in the direction where an electric wire extends.

前記底板に、前記バレル片が形成された領域よりも前記電線の延びる方向について外方の位置に前記凹部を形成されていてもよい。   The recess may be formed on the bottom plate at an outer position in a direction in which the electric wire extends than an area where the barrel piece is formed.

上記の態様によれば、底板のうちバレル片が形成された領域が電線の延びる方向に伸びるのを、確実に抑制できる。   According to said aspect, it can suppress reliably that the area | region in which the barrel piece was formed among baseplates extends in the direction where an electric wire extends.

前記芯線はアルミニウム又はアルミニウム合金からなる構成としてもよい。   The core wire may be made of aluminum or an aluminum alloy.

芯線がアルミニウム又はアルミニウム合金からなる場合、芯線の表面には酸化膜が比較的に形成されやすい。上記の構成は、芯線の表面に酸化膜が形成されやすい場合に有効である。   When the core wire is made of aluminum or an aluminum alloy, an oxide film is relatively easily formed on the surface of the core wire. The above configuration is effective when an oxide film is easily formed on the surface of the core wire.

本発明によれば、バレル片を芯線に圧着する前後において、電線の延びる方向について端子金具の長さ寸法が大きくなることを抑制できる。   ADVANTAGE OF THE INVENTION According to this invention, before and after crimping | bonding a barrel piece to a core wire, it can suppress that the length dimension of a terminal metal fitting becomes large about the extending direction of an electric wire.

The female terminal fitting 12 is formed by pressing a metal plate material into a predetermined shape. As the metal plate material, any metal such as copper or copper alloy can be used as necessary. In this embodiment, copper or a copper alloy is used.

図２に示すように、電線１１が載置される底板１５と、この底板１５の側縁から側方に突出して電線１１の絶縁被覆１４の外側から巻き付くように圧着される一対のインシュレーションバレル片１６と、底板１５の側縁のうちインシュレーションバレル片１６よりも電線１１の端部側（図２において左側）に位置する側縁から側方に延びて芯線１０の外側から巻き付くように圧着される一対のワイヤーバレル片１７（特許請求の範囲に記載のバレル片に相当）と、底板１５から延びて図示しない雄端子金具と接続される接続部１８と、を備える。底板１５は、電線１１の延びる方向(図２における矢線Ａで示す方向）に細長く延びて形成されている。   As shown in FIG. 2, a bottom plate 15 on which the electric wire 11 is placed, and a pair of insulations that are crimped so as to protrude laterally from the side edge of the bottom plate 15 and wind from the outside of the insulating coating 14 of the electric wire 11. The barrel piece 16 and the side edge of the bottom plate 15 extend laterally from the side edge located on the end portion side (left side in FIG. 2) of the electric wire 11 relative to the insulation barrel piece 16 so as to be wound from the outside of the core wire 10. A pair of wire barrel pieces 17 (corresponding to the barrel pieces described in the claims) and a connection portion 18 extending from the bottom plate 15 and connected to a male terminal fitting (not shown). The bottom plate 15 is formed to be elongated in the direction in which the electric wire 11 extends (the direction indicated by the arrow A in FIG. 2).

図１に示すように、接続部１８は角筒状をなしており、雄端子金具が挿入可能になっている。接続部１８の内部には弾性変形可能な弾性接触片（図示せず）が形成されており、この弾性接触片が雄端子金具と弾性的に接触することにより、雄端子金具と雌端子金具１２とが電気的に接続される。   As shown in FIG. 1, the connecting portion 18 has a rectangular tube shape, and a male terminal fitting can be inserted. An elastic contact piece (not shown) that can be elastically deformed is formed inside the connecting portion 18, and the elastic contact piece makes elastic contact with the male terminal fitting, whereby the male terminal fitting and the female terminal fitting 12 are provided. Are electrically connected.

図２に示すように、芯線１０に圧着する前の状態においては、ワイヤーバレル片１７は概ね矩形状をなしている。電線１１は、ワイヤーバレル片１７が芯線１０に圧着された状態では、図２における左右方向（矢線Ａで示す方向）に延びて配されるようになっている。   As shown in FIG. 2, the wire barrel piece 17 has a generally rectangular shape before being crimped to the core wire 10. In a state where the wire barrel piece 17 is crimped to the core wire 10, the electric wire 11 extends in the left-right direction in FIG. 2 (the direction indicated by the arrow A).

底板１５及びワイヤーバレル片１７のうち、芯線１０と接触する側（図２における紙面を貫通する方向手前側）の面は、接触面２０とされる。底板１５及びワイヤーバレル片１７の接触面２０には、電線１１の延びる方向（図２において矢線Ａで示す方向）と交差する方向（図２において矢線Ｂで示す方向）に延びる複数（本実施形態では３本）の溝２１が形成されている。本実施形態においては、溝２１は電線１１の延びる方向と直交して形成されている。   Of the bottom plate 15 and the wire barrel piece 17, the surface on the side in contact with the core wire 10 (the front side in the direction passing through the paper surface in FIG. 2) is the contact surface 20. On the contact surface 20 of the bottom plate 15 and the wire barrel piece 17, a plurality of (books) extending in a direction (direction indicated by arrow B in FIG. 2) intersecting with the direction in which the electric wire 11 extends (direction indicated by arrow A in FIG. 2) In the embodiment, three grooves 21 are formed. In the present embodiment, the groove 21 is formed orthogonal to the direction in which the electric wire 11 extends.

（電線１１と雌端子金具１２との接続構造）
図３に示すように、一対のワイヤーバレル片１７は芯線１０の外側に巻き付くように圧着される。ワイヤーバレル片１７は、芯線１０を底板１５に載置した状態でアンビル３０に載置し、その後、アンビル３０の上方に位置して配されたクリンパ３１を、上方からアンビル３０側に向けて移動させ、アンビル３０とクリンパ３１との間でワイヤーバレル片１７を挟んで押圧することにより、芯線１０に押圧されるようになっている。 (Connection structure between the electric wire 11 and the female terminal fitting 12)
As shown in FIG. 3, the pair of wire barrel pieces 17 are crimped so as to be wound around the outside of the core wire 10. The wire barrel piece 17 is placed on the anvil 30 with the core wire 10 placed on the bottom plate 15, and then the crimper 31 disposed above the anvil 30 is moved from above toward the anvil 30 side. By pressing the wire barrel piece 17 between the anvil 30 and the crimper 31, the core wire 10 is pressed.

芯線１０にワイヤーバレル片１７が巻き付くように圧着されることにより、芯線１０にはワイヤーバレル片１７から圧力が加えられる。すると、芯線１０の表面に形成された酸化膜が破れて芯線１０の新生面が露出し、この新生面と、底板１５及びワイヤーバレル片１７の接触面２０とが接触することにより、電線１１と雌端子金具１２とが電気的に接続される。   A pressure is applied to the core wire 10 from the wire barrel piece 17 by being crimped so that the wire barrel piece 17 is wound around the core wire 10. Then, the oxide film formed on the surface of the core wire 10 is broken, and the new surface of the core wire 10 is exposed, and the new surface and the contact surface 20 of the bottom plate 15 and the wire barrel piece 17 come into contact with each other. The metal fitting 12 is electrically connected.

また、ワイヤーバレル片１７から圧力が加えられることにより、芯線１０が塑性変形し、底板１５及びワイヤーバレル片１７の接触面２０に形成された溝２１内に入り込む。すると、溝２１の開口縁に形成されたエッジと、芯線１０の表面と、が摺接することにより、芯線１０の酸化膜が剥ぎ取られて芯線１０の新生面が露出する。この新生面と、底板１５及びワイヤーバレル片１７の接触面２０と、が接触することにより、電線１１と雌端子金具１２との電気的接続を確実なものとなっている。   Further, when the pressure is applied from the wire barrel piece 17, the core wire 10 is plastically deformed and enters the groove 21 formed in the contact surface 20 of the bottom plate 15 and the wire barrel piece 17. Then, the edge formed at the opening edge of the groove 21 and the surface of the core wire 10 are in sliding contact with each other, whereby the oxide film of the core wire 10 is peeled off and the new surface of the core wire 10 is exposed. The new surface and the contact surface 20 of the bottom plate 15 and the wire barrel piece 17 are in contact with each other, so that the electrical connection between the electric wire 11 and the female terminal fitting 12 is ensured.

図２に示すように、底板１５のうち、ワイヤーバレル片１７が形成された領域よりも、電線１１の延びる方向（図２において矢線Ａで示す方向）について外方に位置には、複数（本実施形態では一対）の凸部３２が、底板１５の接触面２０と反対側の面（図２において紙面を貫通する方向奥側の面）に突出して設けられている。凸部３２は、電線１１の延びる方向と交差する方向（図２において矢線Ｂで示す方向）に延びて形成されている。本実施形態においては、凸部３２は電線１１の延びる方向と直交して形成されている。 (Convex portion 32)
As shown in FIG. 2, there are a plurality of (in a position outward from the region where the wire barrel piece 17 is formed in the bottom plate 15 in the direction in which the electric wire 11 extends (the direction indicated by the arrow A in FIG. 2) ( In the present embodiment, a pair of convex portions 32 are provided so as to protrude from the surface opposite to the contact surface 20 of the bottom plate 15 (the back surface in the direction penetrating the paper surface in FIG. 2). The convex portion 32 is formed to extend in a direction intersecting with the extending direction of the electric wire 11 (direction indicated by an arrow B in FIG. 2). In the present embodiment, the convex portion 32 is formed orthogonal to the direction in which the electric wire 11 extends.

図３に示すように、アンビル３０の上面には、底板１５に形成された凸部３２に対応する位置に、複数（本実施形態では一対）の凹部３３が形成されている。底板１５がアンビル３０の上面に載置される際には、底板１５の凸部３２は、アンビル３０の凹部３３内に挿入されるようになっている。   As shown in FIG. 3, a plurality (a pair in this embodiment) of concave portions 33 are formed on the upper surface of the anvil 30 at positions corresponding to the convex portions 32 formed on the bottom plate 15. When the bottom plate 15 is placed on the upper surface of the anvil 30, the convex portion 32 of the bottom plate 15 is inserted into the concave portion 33 of the anvil 30.

凸部３２の外側面と、凹部３３の内側面とは、ワイヤーバレル片１７が芯線１０に圧着される工程において当接していればよく、底板１５がアンビル３０に載置されただけの状態においては、凸部３２の外側面と、凹部３３の内側面とは当接していてもよいし、また、離間していてもよい。   The outer surface of the convex portion 32 and the inner surface of the concave portion 33 may be in contact with each other in the process of crimping the wire barrel piece 17 to the core wire 10, and the bottom plate 15 is simply placed on the anvil 30. The outer surface of the convex portion 32 and the inner surface of the concave portion 33 may be in contact with each other or may be separated from each other.

続いて、本実施形態の製造工程の一例を説明する。まず、金属板材を所定形状にプレス成形する。このとき、図２に示すように溝２１を形成してもよい。また、このときに凸部３２を形成してもよい。   Then, an example of the manufacturing process of this embodiment is demonstrated. First, a metal plate material is press-formed into a predetermined shape. At this time, a groove 21 may be formed as shown in FIG. Moreover, you may form the convex part 32 at this time.

次に、金属板材を曲げ加工して接続部１８を形成する。このとき溝２１を形成してもよい。また、このときに凸部３２を形成してもよい。これにより雌端子金具１２が形成される。   Next, the connecting portion 18 is formed by bending the metal plate material. At this time, the groove 21 may be formed. Moreover, you may form the convex part 32 at this time. Thereby, the female terminal fitting 12 is formed.

続いて、図４に示すように、アンビル３０の上に、底板１５に形成された凸部３２をアンビル３０に形成された凹部３３内に挿入させつつ、底板１５を載置する。   Subsequently, as shown in FIG. 4, the bottom plate 15 is placed on the anvil 30 while the convex portions 32 formed on the bottom plate 15 are inserted into the concave portions 33 formed on the anvil 30.

続いて、電線１１の端部に位置する絶縁被覆１４を剥がして芯線１０を露出させる。図３に示すように、露出した芯線１０を雌端子金具１２の底板１５の上に載置する。芯線１０は、底板１５をアンビル３０の上に載置する前に、底板１５の上に載置してもよい。   Subsequently, the insulation coating 14 located at the end of the electric wire 11 is peeled off to expose the core wire 10. As shown in FIG. 3, the exposed core wire 10 is placed on the bottom plate 15 of the female terminal fitting 12. The core wire 10 may be placed on the bottom plate 15 before placing the bottom plate 15 on the anvil 30.

その後、クリンパ３１をアンビル３０に向かって下方に移動させる（図３における矢線Ｃで示す方向）。すると、クリンパ３１とアンビル３０との間に挟まれることにより、ワイヤーバレル片１７が芯線１０の外側に巻き付くように圧着される。これにより端子金具付き電線１３が完成する（図１参照）。   Thereafter, the crimper 31 is moved downward toward the anvil 30 (the direction indicated by the arrow C in FIG. 3). Then, by being sandwiched between the crimper 31 and the anvil 30, the wire barrel piece 17 is crimped so as to be wound around the outside of the core wire 10. Thereby, the electric wire 13 with a terminal metal fitting is completed (refer FIG. 1).

続いて、本実施形態の作用、効果について説明する。本実施形態によれば、芯線１０にワイヤーバレル片１７が巻き付くように圧着されることにより、芯線１０にはワイヤーバレル片１７から圧力が加えられる。すると、芯線１０の表面に形成された酸化膜が破れて芯線１０の新生面が露出し、この新生面と、底板１５及びワイヤーバレル片１７の接触面２０とが接触することにより、電線１１と雌端子金具１２とが電気的に接続される。   Then, the effect | action and effect of this embodiment are demonstrated. According to the present embodiment, pressure is applied to the core wire 10 from the wire barrel piece 17 by being crimped so that the wire barrel piece 17 is wound around the core wire 10. Then, the oxide film formed on the surface of the core wire 10 is broken, and the new surface of the core wire 10 is exposed, and the new surface and the contact surface 20 of the bottom plate 15 and the wire barrel piece 17 come into contact with each other. The metal fitting 12 is electrically connected.

また、ワイヤーバレル片１７から圧力が加えられることにより、芯線１０が塑性変形し、底板１５及びワイヤーバレル片１７の接触面２０に形成された溝２１内に入り込む。すると、溝２１の開口縁に形成されたエッジと、芯線１０の表面と、が摺接することにより、芯線１０の酸化膜が剥ぎ取られて芯線１０の新生面が露出する。この新生面と、底板１５及びワイヤーバレル片１７の接触面２０と、が接触することにより、電線１１と雌端子金具１２との電気的接続を確実なものとなっている。   Further, when the pressure is applied from the wire barrel piece 17, the core wire 10 is plastically deformed and enters the groove 21 formed in the contact surface 20 of the bottom plate 15 and the wire barrel piece 17. Then, the edge formed at the opening edge of the groove 21 and the surface of the core wire 10 are in sliding contact with each other, whereby the oxide film of the core wire 10 is peeled off and the new surface of the core wire 10 is exposed. The new surface and the contact surface 20 of the bottom plate 15 and the wire barrel piece 17 are in contact with each other, so that the electrical connection between the electric wire 11 and the female terminal fitting 12 is ensured.

また、ワイヤーバレル片１７を芯線１０に圧着すると、芯線１０を介して底板１５に圧力が加わる。すると、底板１５は、電線１１の延びる方向（図４における矢線Ａで示す方向）に塑性変形して伸びようとする。すると、底板１５に形成された凸部３２は、アンビル３０に形成された凹部３３内に挿入されているので、凸部３２の外側面が凹部３３の内側面と当接する。   Further, when the wire barrel piece 17 is pressure-bonded to the core wire 10, pressure is applied to the bottom plate 15 through the core wire 10. Then, the bottom plate 15 tends to extend by plastic deformation in the direction in which the electric wire 11 extends (the direction indicated by the arrow A in FIG. 4). Then, since the convex portion 32 formed on the bottom plate 15 is inserted into the concave portion 33 formed on the anvil 30, the outer surface of the convex portion 32 comes into contact with the inner surface of the concave portion 33.

この結果、電線１１の延びる方向について凸部３２が変位することが凹部３３によって抑制される。すると、底板１５のうち一対の凸部３２の間に位置する領域が、電線１１の延びる方向について伸びることを抑制できる。これにより、電線１１の延びる方向について、雌端子金具１２長さ寸法が大きくなることを抑制できる。   As a result, the concave portion 33 suppresses the convex portion 32 from being displaced in the extending direction of the electric wire 11. Then, it can suppress that the area | region located between a pair of convex parts 32 among the baseplates 15 extends about the direction where the electric wire 11 is extended. Thereby, it can suppress that the female terminal metal fitting 12 length dimension becomes large about the direction where the electric wire 11 is extended.

また、本実施形態によれば、凸部３２は、底板１５のうち、ワイヤーバレル片１７が形成された領域よりも、電線１１の延びる方向について外方の位置に形成されている。これにより、底板１５のうちワイヤーバレル片１７が形成された領域が電線１１の延びる方向に伸びるのを、確実に抑制できる。   Moreover, according to this embodiment, the convex part 32 is formed in the outward position about the direction where the electric wire 11 extends rather than the area | region in which the wire barrel piece 17 was formed among the baseplates 15. FIG. Thereby, it can suppress reliably that the area | region in which the wire barrel piece 17 was formed among the baseplates 15 extended in the direction where the electric wire 11 is extended.

また、本実施形態においては、芯線１０はアルミニウム又はアルミニウム合金からなる。このように、芯線１０がアルミニウム又はアルミニウム合金からなる場合、芯線１０の表面には酸化膜が比較的に形成されやすい。このため、芯線１０の酸化膜を剥ぎ取ろうとすると、比較的に大きな圧力によって、ワイヤーバレルを芯線１０に圧着する必要がある。すると、ワイヤーバレルも塑性変形しやすくなる。本実施形態は、上記のように比較的に強い圧力でワイヤーバレルを芯線１０に圧着する場合に有効である。   In the present embodiment, the core wire 10 is made of aluminum or an aluminum alloy. Thus, when the core wire 10 is made of aluminum or an aluminum alloy, an oxide film is relatively easily formed on the surface of the core wire 10. For this reason, when it is going to peel off the oxide film of the core wire 10, it is necessary to crimp | bond a wire barrel to the core wire 10 with a comparatively big pressure. Then, the wire barrel is also easily plastically deformed. This embodiment is effective when the wire barrel is crimped to the core wire 10 with a relatively strong pressure as described above.

＜実施形態２＞
次に、本発明の実施形態２を図５及び図６を参照しつつ説明する。なお、実施形態１と同一部材については同一符号を付し、重複する説明を省略する。図６に示すように、底板１５には、ワイヤーバレル片１７が形成された領域よりも、電線１１の延びる方向（図６において矢線Ａで示す方向）について外方に位置して、複数（本実施形態では一対）の貫通孔４０（特許請求の範囲に記載の凹部に相当）が、底板１５を貫通して設けられている。詳細には図示しないが貫通孔４０は、電線１１の延びる方向と交差する方向（図６において紙面を貫通する方向）に延びて形成されている。本実施形態においては、貫通孔４０は電線１１の延びる方向と直交して形成されている。 <Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIGS. In addition, about the same member as Embodiment 1, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted. As shown in FIG. 6, the bottom plate 15 has a plurality of (in the direction in which the electric wire 11 extends (the direction indicated by the arrow A in FIG. 6) outward from the region where the wire barrel pieces 17 are formed. In the present embodiment, a pair of through holes 40 (corresponding to the recesses described in the claims) are provided through the bottom plate 15. Although not shown in detail, the through hole 40 is formed so as to extend in a direction intersecting with the extending direction of the electric wire 11 (a direction penetrating the paper surface in FIG. 6). In the present embodiment, the through hole 40 is formed orthogonal to the direction in which the electric wire 11 extends.

図５及び図６に示すように、アンビル３０の上面には、底板１５に形成された貫通孔４０に対応する位置に、複数（本実施形態では一対）の凸部４２が形成されている。底板１５がアンビル３０の上面に載置される際には、アンビル３０の凸部４２は、底板１５の貫通孔４０内に挿入されるようになっている。   As shown in FIGS. 5 and 6, a plurality (a pair in this embodiment) of convex portions 42 are formed on the upper surface of the anvil 30 at positions corresponding to the through holes 40 formed in the bottom plate 15. When the bottom plate 15 is placed on the upper surface of the anvil 30, the convex portion 42 of the anvil 30 is inserted into the through hole 40 of the bottom plate 15.

凸部４２の外側面と、貫通孔４０の内側面とは、ワイヤーバレル片１７が芯線１０に圧着される工程において当接していればよく、底板１５がアンビル３０に載置されただけの状態においては、凸部４２の外側面と、貫通孔４０の内側面とは当接していてもよいし、また、離間していてもよい。   The outer side surface of the convex part 42 and the inner side surface of the through-hole 40 need only be in contact with each other in the step of crimping the wire barrel piece 17 to the core wire 10, and the bottom plate 15 is simply placed on the anvil 30. , The outer side surface of the convex portion 42 and the inner side surface of the through hole 40 may be in contact with each other or may be separated from each other.

続いて、本実施形態の製造工程の一例を説明する。まず、金属板材を所定形状にプレス成形する。このとき、溝２１を形成してもよい。また、このときに貫通孔４０を形成してもよい。   Then, an example of the manufacturing process of this embodiment is demonstrated. First, a metal plate material is press-formed into a predetermined shape. At this time, the groove 21 may be formed. At this time, the through hole 40 may be formed.

次に、金属板材を曲げ加工して接続部１８を形成する。このとき溝２１を形成してもよい。また、このときに貫通孔４０を形成してもよい。これにより雌端子金具１２が形成される。   Next, the connecting portion 18 is formed by bending the metal plate material. At this time, the groove 21 may be formed. At this time, the through hole 40 may be formed. Thereby, the female terminal fitting 12 is formed.

続いて、図６に示すように、アンビル３０の上に、アンビル３０に形成された凸部３２を、底板１５に形成された貫通孔４０内に挿入させつつ、底板１５を載置する。   Subsequently, as shown in FIG. 6, the bottom plate 15 is placed on the anvil 30 while the convex portions 32 formed on the anvil 30 are inserted into the through holes 40 formed in the bottom plate 15.

続いて、電線１１の端部に位置する絶縁被覆１４を剥がして芯線１０を露出させる。図５に示すように、露出した芯線１０を雌端子金具１２の底板１５の上に載置する。芯線１０は、底板１５をアンビル３０の上に載置する前に、底板１５の上に載置してもよい。   Subsequently, the insulation coating 14 located at the end of the electric wire 11 is peeled off to expose the core wire 10. As shown in FIG. 5, the exposed core wire 10 is placed on the bottom plate 15 of the female terminal fitting 12. The core wire 10 may be placed on the bottom plate 15 before placing the bottom plate 15 on the anvil 30.

その後、クリンパ３１をアンビル３０に向かって下方に移動させる（図５における矢線Ｃで示す方向）。すると、クリンパ３１とアンビル３０との間に挟まれることにより、ワイヤーバレル片１７が芯線１０の外側に巻き付くように圧着される。これにより端子金具付き電線１３が完成する。   Thereafter, the crimper 31 is moved downward toward the anvil 30 (the direction indicated by the arrow C in FIG. 5). Then, by being sandwiched between the crimper 31 and the anvil 30, the wire barrel piece 17 is crimped so as to be wound around the outside of the core wire 10. Thereby, the electric wire 13 with a terminal metal fitting is completed.

続いて、本実施形態の作用、効果について説明する。ワイヤーバレル片１７を芯線１０に圧着すると、芯線１０を介して底板１５に圧力が加わる。すると、底板１５は、電線１１の延びる方向（図６における矢線Ａで示す方向）に塑性変形して伸びようとする。すると、アンビル３０に形成された凸部３２は、底板１５に形成された貫通孔４０内に挿入されているので、凸部３２の外側面が貫通孔４０の内側面と当接する。   Then, the effect | action and effect of this embodiment are demonstrated. When the wire barrel piece 17 is crimped to the core wire 10, pressure is applied to the bottom plate 15 through the core wire 10. Then, the bottom plate 15 tries to extend by plastic deformation in the direction in which the electric wire 11 extends (the direction indicated by the arrow A in FIG. 6). Then, since the convex part 32 formed in the anvil 30 is inserted into the through hole 40 formed in the bottom plate 15, the outer side surface of the convex part 32 comes into contact with the inner side surface of the through hole 40.

この結果、電線１１の延びる方向について貫通孔４０が変位することが凸部３２によって抑制される。すると、底板１５のうち一対の貫通孔４０の間に位置する領域が、電線１１の延びる方向について伸びることを抑制できる。これにより、電線１１の延びる方向について、雌端子金具１２長さ寸法が大きくなることを抑制できる。   As a result, the protrusion 32 suppresses the displacement of the through hole 40 in the direction in which the electric wire 11 extends. Then, the area | region located between a pair of through-holes 40 among the baseplates 15 can suppress extending about the direction where the electric wire 11 is extended. Thereby, it can suppress that the female terminal metal fitting 12 length dimension becomes large about the direction where the electric wire 11 is extended.

また、本実施形態によれば、貫通孔４０は、底板１５のうち、ワイヤーバレル片１７が形成された領域よりも、電線１１の延びる方向について外方の位置に形成されている。これにより、底板１５のうちワイヤーバレル片１７が形成された領域が電線１１の延びる方向に伸びるのを、確実に抑制できる。   Further, according to the present embodiment, the through hole 40 is formed at an outer position in the extending direction of the electric wire 11 than the region of the bottom plate 15 where the wire barrel piece 17 is formed. Thereby, it can suppress reliably that the area | region in which the wire barrel piece 17 was formed among the baseplates 15 extended in the direction where the electric wire 11 is extended.
