本発明の実施例に係る圧着端子１は、電線１０の端末部に取り付けるものである。
まず、電線１０について説明する。 FIG. 1 is a perspective view of a crimp terminal 1 according to an embodiment of the present invention. 2 is a cross-sectional view of the crimp terminal 1 shown in FIG. 3A is a perspective view of the electric wire 10 for crimping the crimp terminal 1, and FIG. 3B is a front view of the electric wire 10 of FIG.
The crimp terminal 1 according to the embodiment of the present invention is attached to the terminal portion of the electric wire 10.
First, the electric wire 10 will be described.

電線１０は、導体部１１と導体部１１の外周を包囲する絶縁被覆部１２とを有する。
導体部１１は、アルミニウム、あるいはアルミニウム合金等の導電性の線材からなる複数の素線１１ａが束ねられてなる。
なお、導体部１１は、複数の素線１１ａが束ねられてなるものを例示したが、これに限らず単芯線からなるものであっても構わない。
絶縁被覆部１２は、絶縁性の合成樹脂からなり、導体部１１の外周を包囲するように形成されることによって、導体部１１を外部から絶縁可能に保護するものである。
この電線１０の先端部は、絶縁被覆部１２を剥がすことによって導体部１１を露出させている。この露出した導体部１１に圧着端子１の後述する導体圧着部３０を圧着するようになっている。 The electric wire 10 includes a conductor portion 11 and an insulating coating portion 12 that surrounds the outer periphery of the conductor portion 11.
The conductor portion 11 is formed by bundling a plurality of strands 11a made of a conductive wire such as aluminum or an aluminum alloy.
In addition, although the conductor part 11 illustrated what bundled the some strand 11a, it may consist of not only this but a single core wire.
The insulation coating portion 12 is made of an insulating synthetic resin, and is formed so as to surround the outer periphery of the conductor portion 11, thereby protecting the conductor portion 11 from the outside.
The conductor portion 11 is exposed at the distal end portion of the electric wire 10 by peeling off the insulating coating portion 12. A conductor crimping portion 30 (to be described later) of the crimp terminal 1 is crimped to the exposed conductor portion 11.

次に、圧着端子１について説明する。
圧着端子１は、銅、あるいは銅合金等の金属からなる板状部材が金型プレス加工等によって成形されたものである。この圧着端子１は、電線１０の端末部１０ａに圧着する圧着部２０と、電線１０の不図示の接続相手に接続する相手接続部６０と、圧着部２０と、相手接続部６０との間を繋ぐ繋ぎ部７０と、を有する。 Next, the crimp terminal 1 will be described.
The crimp terminal 1 is obtained by molding a plate-like member made of metal such as copper or copper alloy by die press working or the like. The crimp terminal 1 includes a crimp portion 20 that crimps the terminal portion 10 a of the electric wire 10, a mating connection portion 60 that is connected to a connection partner (not shown) of the electric wire 10, a crimp portion 20, and a mating connection portion 60. And a connecting portion 70 to be connected.

相手接続部６０は、角筒状をなす接続本体部６１の筒内に設けられた弾性接触片６１ａに接続相手が接触されるようになっている。この相手接続部６０は、接続相手としての雄端子が接続する雌端子を構成している。
なお、相手接続部６０は、雌端子を構成するものを例示したが、これに限らず、接続相手に接続できる構成になっていれば、その他の端子構成であっても構わない。 The mating connection portion 60 is configured such that the mating connection is brought into contact with an elastic contact piece 61 a provided in the cylinder of the connection main body 61 having a rectangular tube shape. The counterpart connection portion 60 constitutes a female terminal to which a male terminal as a connection counterpart is connected.
In addition, although the other party connection part 60 illustrated what comprises a female terminal, if it becomes the structure which can connect to a connection other party not only this, you may be another terminal structure.

圧着部２０は、電線１０の延在方向に並んで２箇所に設けている。
１つの圧着部２０は、電線１０の露出した導体部１１に圧着する導体圧着部３０であり、もう１つの圧着部２０は、電線１０の絶縁被覆部１２に圧着する被覆圧着部４０である。これら導体圧着部３０と被覆圧着部４０との間は中間部５０によって連結している。 The crimp part 20 is provided in two places along with the extending direction of the electric wire 10.
One crimping portion 20 is a conductor crimping portion 30 that crimps the exposed conductor portion 11 of the electric wire 10, and the other crimping portion 20 is a covering crimping portion 40 that crimps the insulating coating portion 12 of the electric wire 10. The conductor crimping part 30 and the covering crimping part 40 are connected by an intermediate part 50.

導体圧着部３０は、繋ぎ部７０に連接し、かつ、電線１０の先端に露出した導体部１１に圧着する部分である。   The conductor crimping portion 30 is a portion that is connected to the connecting portion 70 and is crimped to the conductor portion 11 exposed at the tip of the electric wire 10.

導体圧着部３０は、底壁としての導体側底壁３１ａおよび導体側底壁３１ａの両縁に立設する一対の側壁としての一対の導体側側壁３１ｂ、３１ｂを有し、かつ、圧着変形後の形状に近似した形状をなして繋ぎ部７０を形成する壁に連接する非変形圧着壁部３１と、一対の導体側側壁３１ｂ、３１ｂの各導体側側壁３１ｂの上端側を繋ぎ部７０より高く延在するように設け、かつ、電線１０を包み込むようにして電線１０に圧着する一対の圧着片部としての一対の導体圧着片部３２、３２と、を有する。   The conductor crimping portion 30 has a conductor side bottom wall 31a as a bottom wall and a pair of conductor side walls 31b and 31b as a pair of side walls standing on both edges of the conductor side bottom wall 31a. The non-deformation crimp wall 31 connected to the wall forming the connecting portion 70 with a shape similar to the shape of the above and the upper end side of each of the conductor-side side walls 31b of the pair of conductor-side side walls 31b, 31b are higher than the connecting portion 70. It has a pair of conductor crimping piece portions 32 and 32 as a pair of crimping piece portions that are provided so as to extend and are crimped to the electric wire 10 so as to enclose the electric wire 10.

非変形圧着壁部３１は、圧着端子１の前後方向に直交する断面が圧着変形後の形状に近似した略Ｕ字形状をなしている。すなわち、非変形圧着壁部３１は、電線１０への圧着の際に変形し難い形状になっている。   The non-deformable crimp wall portion 31 has a substantially U-shaped cross section orthogonal to the front-rear direction of the crimp terminal 1 that approximates the shape after crimp deformation. That is, the non-deformable crimp wall 31 has a shape that is not easily deformed when crimping to the electric wire 10.

導体側底壁３１ａは、繋ぎ部７０から被覆圧着部４０まで連続する底壁１ａの一部をなし、電線１０に圧着する際の導体圧着部３０の下側の型となる不図示のアンビルの型面に沿った形状をなしている。   The conductor-side bottom wall 31a forms a part of the bottom wall 1a continuous from the connecting portion 70 to the covering crimping portion 40, and is an unillustrated anvil that is a lower mold of the conductor crimping portion 30 when crimping to the electric wire 10. It has a shape along the mold surface.

一対の導体側側壁３１ｂ、３１ｂは、繋ぎ部７０の一対の繋ぎ側壁７１ｂ、７１ｂと上端面を揃えるように高さを調整している。
このため、非変形圧着壁部３１は、繋ぎ部７０の繋ぎ底壁７１ａおよび一対の繋ぎ側壁７１ｂ、７１ｂと、導体側底壁３１ａおよび一対の導体側側壁３１ｂ、３１ｂを連接することによって、繋ぎ部７０と連続的につながるようになっている。 The heights of the pair of conductor side walls 31b and 31b are adjusted so that the pair of connecting side walls 71b and 71b of the connecting portion 70 are aligned with the upper end surface.
Therefore, the non-deformation crimp wall 31 is connected by connecting the connecting bottom wall 71a and the pair of connecting side walls 71b and 71b to the conductor side bottom wall 31a and the pair of conductor side walls 31b and 31b. The unit 70 is continuously connected.

一対の導体圧着片部３２、３２は、電線１０の導体部１１に圧着する際に、不図示のクリンパによって大きく内側に変形しながら導体部１１に圧着するようになっている。
この一対の導体圧着片部３２、３２は繋ぎ部７０の一対の繋ぎ側壁７１ｂ、７１ｂより高い位置で非変形圧着壁部３１から延在されている。 The pair of conductor crimping pieces 32 and 32 are adapted to be crimped to the conductor 11 while being largely deformed inward by a crimper (not shown) when crimping to the conductor 11 of the electric wire 10.
The pair of conductor crimping pieces 32, 32 are extended from the non-deformation crimping wall 31 at a position higher than the pair of joining side walls 71 b, 71 b of the joint 70.

被覆圧着部４０は、中間部５０を間にすることによって導体圧着部３０と離間して設け、導体部１１を絶縁被覆する絶縁被覆部１２に圧着する部分である。
この被覆圧着部４０は、繋ぎ部７０から被覆圧着部４０まで連続する底壁１ａの一部をなす被覆側底壁４１ａと、被覆側底壁４１ａの両縁に立設する一対の被覆側側壁４１ｂ、４１ｂと、一対の被覆側側壁４１ｂ、４１ｂの各被覆側側壁４１ｂの上端側を延在することによって電線１０の絶縁被覆部１２を包み込むようにして絶縁被覆部１２に圧着する一対の被覆圧着片部４２、４２と、を有する。 The covering crimping portion 40 is a portion that is provided so as to be separated from the conductor crimping portion 30 with the intermediate portion 50 interposed therebetween, and is crimped to the insulating covering portion 12 that insulates and coats the conductor portion 11.
The covering crimping portion 40 includes a covering side bottom wall 41a that forms a part of the bottom wall 1a continuous from the connecting portion 70 to the covering crimping portion 40, and a pair of covering side walls that stand on both edges of the covering side bottom wall 41a. 41b, 41b and a pair of coatings that are crimped to the insulation coating portion 12 so as to wrap around the insulation coating portion 12 of the electric wire 10 by extending the upper end side of each of the coating side sidewalls 41b of the pair of coating side walls 41b, 41b Pressure-bonding pieces 42, 42.

中間部５０は、繋ぎ部７０から被覆圧着部４０まで連続する底壁１ａの一部をなす中間底壁５１ａと、中間底壁５１ａの両縁に立設する一対の中間側壁５１ｂ、５１ｂと、を有する。   The intermediate portion 50 includes an intermediate bottom wall 51a that forms a part of the bottom wall 1a that continues from the connecting portion 70 to the covering crimping portion 40, and a pair of intermediate side walls 51b and 51b that are erected on both edges of the intermediate bottom wall 51a. Have

繋ぎ部７０は、導体圧着部３０の導体側底壁３１ａに連接する繋ぎ底壁７１ａと、繋ぎ底壁７１ａの両縁に立設する一対の繋ぎ側壁７１ｂ、７１ｂと、を有する。
この繋ぎ部７０は、圧着の際に変形し難い非変形圧着壁部３１と連続的に繋がっている。一方、変形量の大きい一対の導体圧着片部３２、３２が、一対の繋ぎ側壁７１ｂ、７１ｂより高い位置で非変形圧着壁部３１から延在されている。このため、繋ぎ部７０は、導体圧着部３０の変形の影響を受けにくいようになっている。 The connecting portion 70 includes a connecting bottom wall 71a connected to the conductor-side bottom wall 31a of the conductor crimping portion 30, and a pair of connecting side walls 71b and 71b erected on both edges of the connecting bottom wall 71a.
The joint portion 70 is continuously connected to the non-deformation crimp wall portion 31 that is not easily deformed during crimping. On the other hand, the pair of conductor crimping pieces 32, 32 having a large deformation amount extend from the non-deformation crimping wall 31 at a position higher than the pair of connecting side walls 71b, 71b. For this reason, the connecting portion 70 is not easily affected by the deformation of the conductor crimping portion 30.

次に、図４および図５を用いて、圧着端子１の圧着部２０を電線１０に圧着する際に導体圧着部３０が変形する様子について説明する。
図４は、（ａ）が電線１０に圧着端子１を圧着するため電線１０の端末部１０ａを圧着端子１の底壁１ａに載置した状態を示し、（ｂ）が導体圧着部３０を導体部１１に圧着した状態を示した圧着端子１と電線１０との斜視図である。図５は、被覆圧着部４０を絶縁被覆部１２に圧着して圧着端子１を電線１０に圧着完了した状態を示した圧着端子１と電線１０との斜視図である。図６は、（ａ）が図１に示した圧着端子１のＢ−Ｂ線断面であり、（ｂ）が図４に示した圧着端子１と電線１０のＣ−Ｃ線断面図である。 Next, the manner in which the conductor crimping portion 30 is deformed when the crimping portion 20 of the crimping terminal 1 is crimped to the electric wire 10 will be described with reference to FIGS. 4 and 5.
4A shows a state where the terminal portion 10a of the electric wire 10 is placed on the bottom wall 1a of the crimp terminal 1 in order to crimp the crimp terminal 1 to the electric wire 10, and FIG. FIG. 3 is a perspective view of the crimp terminal 1 and the electric wire 10 showing a state of being crimped to a portion 11. FIG. 5 is a perspective view of the crimp terminal 1 and the electric wire 10 showing a state in which the coated crimp part 40 is crimped to the insulating coating part 12 and the crimp terminal 1 is completely crimped to the electric wire 10. 6A is a cross-sectional view taken along line BB of the crimp terminal 1 shown in FIG. 1, and FIG. 6B is a cross-sectional view taken along line CC of the crimp terminal 1 and the electric wire 10 shown in FIG.

まず、作業者によって電線１０の端末部１０ａを圧着端子１の底壁１ａに載置し（図４（ａ）参照）、その後、不図示のアンビルおよびクリンパによって導体圧着部３０を導体部１１に圧着する（図４（ｂ）参照）。
このとき、導体圧着部３０は、圧着前（図６（ａ）参照）に対し着後（図６（ｂ）参照）では、一対の導体圧着片部３２、３２が変形する。
一方、非変形圧着壁部３１は、圧着前にすでに圧着変形後の形状になっているので変形しない。このため、図４（ｂ）に示すように、非変形圧着壁部３１に連接する繋ぎ部７０についても、圧着によって変形しない。 First, the terminal portion 10a of the electric wire 10 is placed on the bottom wall 1a of the crimp terminal 1 by an operator (see FIG. 4A), and then the conductor crimp portion 30 is attached to the conductor portion 11 by an unillustrated anvil and crimper. Crimp (see FIG. 4B).
At this time, the pair of conductor crimping pieces 32 and 32 is deformed after the conductor crimping part 30 is attached (see FIG. 6B) before the crimping (see FIG. 6A).
On the other hand, the non-deformable crimp wall portion 31 is not deformed because it has already been crimped and deformed before crimping. For this reason, as shown in FIG.4 (b), also about the connection part 70 connected with the non-deformation crimping wall part 31, it does not deform | transform by crimping | compression-bonding.

その後、不図示のアンビルおよびクリンパによって被覆圧着部４０を絶縁被覆部１２に圧着して電線１０への圧着端子１の圧着を完了する（図５参照）。
この被覆圧着部４０を絶縁被覆部１２に圧着することによっても、被覆圧着部４０を繋ぎ部７０に連接する導体圧着部３０に離間して設けているので、被覆圧着部４０の圧着による変形は繋ぎ部７０に影響しない。 Then, the crimping | compression-bonding part 40 is crimped | bonded to the insulation coating part 12 by an unillustrated anvil and crimper, and the crimping | compression-bonding of the crimp terminal 1 to the electric wire 10 is completed (refer FIG. 5).
Also by crimping the covering crimping portion 40 to the insulating coating portion 12, the covering crimping portion 40 is provided apart from the conductor crimping portion 30 connected to the connecting portion 70. The connecting portion 70 is not affected.

本発明の実施例に係る圧着端子１は、繋ぎ部７０が圧着の際に変形し難い非変形圧着壁部３１と連続的に繋がる一方、圧着による変形量の大きい一対の導体圧着片３２部が繋ぎ部７０より高い位置で非変形圧着壁部３１から延在されているので、繋ぎ部７０が圧着部２０の変形の影響を受けにくいようになっており、この繋ぎ部７０に連接する相手接続部６０の変形を防止し、結果的に、接続相手との電気的接続安定性が低下することを防ぐことができる。   In the crimp terminal 1 according to the embodiment of the present invention, the connecting portion 70 is continuously connected to the non-deformed crimp wall portion 31 that is difficult to be deformed during crimping, while a pair of conductor crimping pieces 32 having a large deformation amount due to crimping are provided. Since it extends from the non-deformation crimping wall portion 31 at a position higher than the joint portion 70, the joint portion 70 is less susceptible to the deformation of the crimp portion 20, and the mating connection connected to the joint portion 70. The deformation of the portion 60 can be prevented, and as a result, the electrical connection stability with the connection partner can be prevented from being lowered.

また、本発明の実施例に係る圧着端子１は、２箇所の圧着部２０のうち、繋ぎ部７０に連接する側の圧着部２０である導体圧着部３０に非変形圧着壁部３１を設けるようにしているので、効果的かつ効率的に繋ぎ部７０の変形を防ぐことができる。   In addition, the crimp terminal 1 according to the embodiment of the present invention is provided with the non-deformable crimp wall portion 31 on the conductor crimp portion 30 which is the crimp portion 20 on the side connected to the connecting portion 70 among the two crimp portions 20. Therefore, the deformation of the connecting portion 70 can be prevented effectively and efficiently.

なお、本発明の実施例に係る圧着端子１は、圧着部２０が導体圧着部３０と被覆圧着部４０とを離間して設けてなるものを例示したが、これに限らず、導体圧着部３０と被覆圧着部４０とが電線１０の延在方向に連接するようにしても構わない。この場合、圧着部の被覆圧着部に対応する部分についても非変形圧着壁部として機能する部分を設けるとよい。   In addition, although the crimp terminal 1 according to the embodiment of the present invention is illustrated in which the crimp part 20 is provided by separating the conductor crimp part 30 and the coated crimp part 40, the present invention is not limited thereto, and the conductor crimp part 30 is not limited thereto. And the covering crimping portion 40 may be connected in the extending direction of the electric wire 10. In this case, a portion functioning as a non-deformation crimp wall portion may be provided for a portion corresponding to the cover crimp portion of the crimp portion.
