The electric wire 17 is also an aluminum electric wire (the conductor is aluminum or an aluminum alloy, or a conductor (CA wire or the like) covered with these).

また、図１（ｂ）に示すように、端子付電線１４は、電線１７の先端部近傍の絶縁被覆を剥がして導体１７ａを露出させ、導体１７ａを多点接続端子１０の導体接続部１１ａに溶接（後述する第２の実施形態の超音波溶接以外の方法で溶接）し、電線１７の絶縁被覆１７ｂをバレル部１１ｂ，１１ｃにより圧着することによって製造することができる。
さらに、図１（ｃ）に示すように、この端子付電線１４を用いて、アルミニウム板などの金属板１９と突起部１３で抵抗溶接等を施すことによって接続し、接続構造１８を形成することができる。このため、アルミニウムを採用した自動車のボディ等との接続構造を形成することができる。よって、本実施形態の端子付電線１４は、アルミ車体へのボディアースなどに使用することができる。 Further, as shown in FIG. 1B, the terminal-attached electric wire 14 peels off the insulation coating in the vicinity of the tip of the electric wire 17 to expose the conductor 17a, and the conductor 17a becomes the conductor connection portion 11a of the multipoint connection terminal 10.

（効果）
（１）アルミニウム又はアルミニウム合金からなる接続端子を自動車のアルミボディに溶接すると、車体の振動などによって接続端子が疲労破壊を起こし、接続端子が割れる等して断線しまう可能性があった。しかし、本実施形態の多点接続端子１０では、導体接続部１１ａから延在部１５ａ，１５ｂ，１５ｃが３方向に延びており、接続部が多点であるため、負荷を分散することができるとともに、仮に何れか一つの延在部に割れが発生しても、導体接続部から複数の延在部が多方向に延びて形成され、各延在部で自動車のアルミボディに溶接されているため、断線の可能性を低減することができる。 (effect)
(1) When a connection terminal made of aluminum or an aluminum alloy is welded to an aluminum body of an automobile, the connection terminal may be fatigued due to vibration of the vehicle body, and the connection terminal may break and break. However, in the multipoint connection terminal 10 of the present embodiment, the extending portions 15a, 15b, and 15c extend from the conductor connection portion 11a in three directions, and the connection portions are multipoint, so that the load can be distributed. At the same time, even if any one of the extending portions is cracked, a plurality of extending portions are formed extending in multiple directions from the conductor connecting portion and welded to the aluminum body of the automobile at each extending portion. Therefore, the possibility of disconnection can be reduced.

（２）本実施形態の多点接続端子１０では、導体接続部１１ａから延在部１５ａ，１５ｂ，１５ｃが３方向に延びており、従来の構造のように負荷が分散されており、疲労破壊の可能性を低減することができる。また導体接続部から多方向に延在部が延びているため、何れか１つの延在部に割れが生じても、断線を回避でき、疲労破壊の可能性を低減することができる。 (2) In the multipoint connection terminal 10 of the present embodiment, the extending portions 15a, 15b, and 15c extend from the conductor connecting portion 11a in three directions, and the load is distributed as in the conventional structure. The possibility of this can be reduced. Moreover, since the extension part is extended in multiple directions from the conductor connection part, even if a crack arises in any one extension part, a disconnection can be avoided and the possibility of fatigue failure can be reduced.

（３）端子部１５として３つの延在部１５ａ，１５ｂ，１５ｃをそれぞれ９０度ずらした方向に設けているため、自動車のアルミボディ等の金属板１９に溶接した場合、車体の振動などの揺れによる負荷部分を３点に分散することができ、疲労破壊の可能性を低減することができる。 (3) Since the three extending portions 15a, 15b, and 15c are provided as the terminal portions 15 in directions shifted by 90 degrees, when they are welded to a metal plate 19 such as an aluminum body of an automobile, vibrations such as vibrations of the vehicle body It is possible to disperse the load portion due to the three points and reduce the possibility of fatigue failure.

［第２の実施形態］
次に、図２（ａ），（ｂ），（ｃ）を参照して、本発明の第２の実施形態について説明する。この第２の実施の形態は、電線固定部にバレル部を設けていない点、導体接続部２１ａで超音波溶接によって電線を接続した点が第１の実施の形態と異なっている。また、図２（ａ），（ｂ），（ｃ）において、第１の実施形態と同一の構成については同一の符号を付し、以下ではその詳細な説明は省略する。 [Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. 2 (a), (b), and (c). The second embodiment is different from the first embodiment in that a barrel portion is not provided in the wire fixing portion and that the wire is connected by ultrasonic welding at the conductor connection portion 21a. 2A, 2B, and 2C, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted below.

（構成）
図２は、本発明の第２の実施形態を説明する平面図及び側面図であり、（ａ）は多点接続端子、（ｂ）は超音波溶接により多点接続端子と電線とを接続した端子付電線、（ｃ）は端子付電線を対象物に溶接した接続構造を示している。 (Constitution)
2A and 2B are a plan view and a side view illustrating a second embodiment of the present invention, where FIG. 2A is a multi-point connection terminal, and FIG. 2B is a connection of the multi-point connection terminal and an electric wire by ultrasonic welding. An electric wire with terminal, (c) shows a connection structure in which the electric wire with terminal is welded to an object.

本実施形態の多点接続端子２０では、図２（ａ）に示すように、アルミニウムまたはアルミニウム合金により製造され、電線が固定される電線固定部２１と、接続対象と接続される端子部１５とを備えている。また、電線固定部２１は、電線１７の導体１７ａが接続される導体接続部２１ａを備えている。端子部１５は、導体接続部２１ａから３方向に延びる延在部１５ａ，１５ｂ，１５ｃからなり、延在部１５ａに対して、延在部１５ｂ、１５ｃはそれぞれ右側、左側に直角方向に設けられている。また、多点接続端子２０は、アルミニウム母材に打ち抜き加工等を施して形成される。   In the multipoint connection terminal 20 of this embodiment, as shown to Fig.2 (a), it manufactures with aluminum or aluminum alloy, the electric wire fixing | fixed part 21 to which an electric wire is fixed, and the terminal part 15 connected to a connection object, It has. The electric wire fixing portion 21 includes a conductor connecting portion 21a to which the conductor 17a of the electric wire 17 is connected. The terminal portion 15 includes extending portions 15a, 15b, and 15c extending in three directions from the conductor connecting portion 21a. The extending portions 15b and 15c are provided on the right side and the left side in a direction perpendicular to the extending portion 15a, respectively. ing. The multipoint connection terminal 20 is formed by punching an aluminum base material.

また、図２（ｂ）に示すように、端子付電線２４は、電線１７の先端部近傍の絶縁被覆を剥がして導体１７ａを露出させ、導体１７ａを導体接続部２１ａの溶接部２３において超音波溶接により溶着することによって製造することができる。さらに、図２（ｃ）に示すように、この端子付電線２４を用いて、アルミニウム板やアルミニウム合金板などの金属板１９と突起部１３で抵抗溶接等を施すことによって接続し、接続構造２８を形成することができる。このため、アルミニウムを採用した自動車のボディ等との接続構造を形成することができる。よって、本実施形態の端子付電線２４は、アルミ車体へのボディアースなどに使用することができる。   As shown in FIG. 2 (b), the terminal-attached electric wire 24 peels off the insulating coating near the tip of the electric wire 17 to expose the conductor 17a, and the conductor 17a is ultrasonicated at the welded portion 23 of the conductor connecting portion 21a. It can be manufactured by welding by welding. Further, as shown in FIG. 2C, the terminal-attached electric wire 24 is used to connect the metal plate 19 such as an aluminum plate or an aluminum alloy plate by resistance welding or the like at the protruding portion 13, thereby connecting the connection structure 28. Can be formed. For this reason, the connection structure with the body etc. of the motor vehicle which employ | adopted aluminum can be formed. Therefore, the electric wire 24 with a terminal of this embodiment can be used for the body earth | ground to an aluminum vehicle body, etc.

（効果）
（１）端子の材質を銅からアルミニウムに変更すると強度が低下してしまうため、従来の端子構造で自動車のアルミボディに溶接すると、端子に圧着されている電線が車体の振動などによって揺れた場合、一部のスポットに負荷が集中し、疲労破壊を起こしてしまう可能性があった。しかし、本実施形態の多点接続端子２０では、導体接続部２１ａから延在部１５ａ，１５ｂ，１５ｃが３方向に延びており、従来の構造のように負荷が集中する箇所が存在しない。従って、端子がアルミニウム製であっても、疲労破壊の可能性を低減することができる。 (effect)
(1) If the terminal material is changed from copper to aluminum, the strength will decrease. Therefore, when welding to the aluminum body of an automobile with the conventional terminal structure, the wire crimped to the terminal may be shaken by the vibration of the car body. There was a possibility that the load was concentrated on some spots and fatigue failure was caused. However, in the multipoint connection terminal 20 of the present embodiment, the extending portions 15a, 15b, and 15c extend from the conductor connecting portion 21a in three directions, and there is no portion where the load is concentrated unlike the conventional structure. Therefore, even if the terminal is made of aluminum, the possibility of fatigue failure can be reduced.

（２）端子部１５として３つの延在部１５ａ，１５ｂ，１５ｃをそれぞれ９０度ずらした方向に設けているため、自動車のボディ等の金属板１９に溶接した場合、車体の振動などの揺れによる負荷部分を３点に分散することができ、疲労破壊の可能性を低減することができる。 (2) Since the three extending portions 15a, 15b, and 15c are provided as the terminal portions 15 in directions shifted by 90 degrees, when they are welded to the metal plate 19 such as the body of an automobile, they are caused by vibration such as vibration of the vehicle body. The load portion can be distributed to three points, and the possibility of fatigue failure can be reduced.

（３）超音波溶接によってアルミニウムの強固な酸化膜が除去されるため、抵抗上昇を引き起こすことなく、電線１７と多点接続端子２０とを接続することができる。 (3) Since the strong oxide film of aluminum is removed by ultrasonic welding, the electric wire 17 and the multipoint connection terminal 20 can be connected without causing an increase in resistance.

（４）電線１７と多点接続端子２０とが超音波溶接によって接続されているため、第１の実施形態のようなバレル部１１ｂ，１１ｃが不要となる。このため、導体接続部２１ａから端子形状を左右方向に容易に延ばすことができ、端子部１５の形成の自由度が広がる。 (4) Since the electric wire 17 and the multipoint connection terminal 20 are connected by ultrasonic welding, the barrel portions 11b and 11c as in the first embodiment are not necessary. For this reason, a terminal shape can be easily extended in the left-right direction from the conductor connection part 21a, and the freedom degree of formation of the terminal part 15 spreads.

（５）アルミニウムによる多点接続端子２０とアルミ電線による接続であるため、ガルバニック腐食を生じる虞がない。
なお、本実施形態において、電線を固定するための補助として、電線固定部２１にバレル部を設けることもできる。 (5) Since the multipoint connection terminal 20 made of aluminum is connected to the aluminum wire, there is no possibility of causing galvanic corrosion.
In addition, in this embodiment, a barrel part can also be provided in the electric wire fixing part 21 as assistance for fixing an electric wire.
