Description
本発明は、端子圧着電線に関する。 The present invention relates to a terminal crimped electric wire.
従来、端子圧着電線としては、複数本の導体からなる芯線部と、この芯線部の外周を覆う被覆部とを備え、被覆部から露出する芯線部に端子の加締め部としてのワイヤーバレルが加締められて導通されるものが知られている(例えば、特許文献1参照)。 2. Description of the Related Art Conventionally, a terminal crimped electric wire has a core wire portion composed of a plurality of conductors and a covering portion covering the outer periphery of the core wire portion, and a wire barrel as a terminal crimping portion is added to the core wire portion exposed from the covering portion. What is fastened and made conductive is known (see, for example, Patent Document 1).
この端子圧着電線では、複数本の導体からなる芯線部を一対の治具で挟んで超音波振動を与え、表面が粗化された粗化領域を形成させている。そして、粗化領域にワイヤーバレルを加締めることによって、酸化膜などの被膜が剥がされ、芯線部の新生面同士が互いに接触し、電線と端子との間の電気抵抗を低下させている。 In this terminal crimped electric wire, a core wire portion made up of a plurality of conductors is sandwiched between a pair of jigs, and ultrasonic vibration is applied to form a roughened region with a roughened surface. Then, by caulking the wire barrel in the roughened region, the coating such as an oxide film is peeled off, the new surfaces of the core wire portion are in contact with each other, and the electrical resistance between the electric wire and the terminal is reduced.
ところで、上記のような端子圧着電線では、芯線部が複数本の導体からなり、この芯線部に端子の加締め部を加締めている。このように芯線部が複数本の導体からなる場合には、導体1本1本の間に隙間があるので、芯線部が加締め部によって加締められるときに加締め部に掛かる接触圧力が緩和される。 By the way, in the terminal crimping electric wire as described above, the core wire portion is composed of a plurality of conductors, and the crimped portion of the terminal is crimped to the core wire portion. In this way, when the core wire portion is composed of a plurality of conductors, there is a gap between each conductor, so that the contact pressure applied to the caulking portion is reduced when the core wire portion is caulked by the caulking portion. Is done.
しかしながら、芯線部が1本の導体からなる場合には、加締め部による芯線部の加締めの際に、加締め部に掛かる荷重が分散し難くなっている。このため、端子の加締め部において、接触圧力の高い部分と低い部分との差があり、高温や低温などの環境変化によって、特に接触圧力の高い部分でクリープが発生して接触圧力が低下するなど、加締め部で十分な接触圧力を確保することが困難であった。 However, when the core wire portion is made of one conductor, the load applied to the caulking portion is difficult to disperse when the core wire portion is caulked by the caulking portion. For this reason, there is a difference between the high contact pressure portion and the low contact portion in the crimped portion of the terminal, and due to environmental changes such as high temperature and low temperature, creep occurs particularly in the high contact pressure portion and the contact pressure decreases. For example, it has been difficult to secure a sufficient contact pressure at the caulking portion.
そこで、この発明は、1本の導体からなる芯線部におけるクリープの発生を抑制することができる端子圧着電線の提供を目的としている。 Then, this invention aims at provision of the terminal crimping electric wire which can suppress generation | occurrence | production of the creep in the core part which consists of one conductor.
請求項1記載の発明は、1本の導体からなる芯線部と、この芯線部の外周を覆う被覆部とを備え、前記被覆部から露出する前記芯線部に端子の加締め部が加締められて導通される端子圧着電線の製造方法であって、前記芯線部は、前記端子の加締め部に加締められる前の状態で、外周形状が前記加締め部を加締めた状態の内周形状と略同一形状に形成され、前記加締め部は、互いの端部を当接して前記芯線部を挟み込む一対の狭持部を有し、前記芯線部には、前記一対の狭持部の端部を配置させる凹部が設けられることを特徴とする。 The invention according to claim 1 includes a core wire portion made of one conductor and a covering portion that covers an outer periphery of the core wire portion, and a crimp portion of a terminal is crimped to the core wire portion exposed from the covering portion. a method of manufacturing a terminal crimping electric wires to be conductive Te, the core part, the state before being crimped crimping portion of the terminal, the inner peripheral shape of the state where the outer peripheral shape caulked the crimp portion The caulking portion has a pair of holding portions that abut against each other and sandwich the core portion, and the core portion includes ends of the pair of holding portions. and wherein the recess for arranging the parts are al provided.
この端子圧着電線では、端子の加締め部に加締められる前の状態で、芯線部の外周形状が加締め部を加締めた状態の内周形状と略同一形状に形成されているので、加締め部を芯線部に加締めるときに加締め部における接触圧力が均等化され、芯線部におけるクリープの発生を抑制して接触圧力が低下する部分を減少させることができる。 In this terminal crimped electric wire, the outer peripheral shape of the core wire portion is formed in substantially the same shape as the inner peripheral shape of the crimped portion in a state before being crimped to the crimped portion of the terminal. When the fastening portion is crimped to the core wire portion, the contact pressure in the crimping portion is equalized, and the occurrence of creep in the core wire portion can be suppressed to reduce the portion where the contact pressure decreases.
従って、このような端子圧着電線では、1本の導体からなる芯線部におけるクリープの発生を抑制することができ、接触抵抗の増加を抑制することができる。
また、この端子圧着電線では、芯線部に一対の狭持部の端部を配置させる凹部が設けられているので、加締め部において一番接触圧力が高くなる一対の狭持部の端部が位置する部分の接触圧力の上昇を緩和することができ、加締め部における接触圧力をより均等化することができる。
Therefore, in such a terminal crimped electric wire, it is possible to suppress the occurrence of creep in the core portion made of one conductor, and to suppress an increase in contact resistance.
Moreover, in this terminal crimped electric wire, since the recessed part which arrange | positions the edge part of a pair of clamping part in the core wire part is provided, the edge part of a pair of clamping part in which a contact pressure becomes the highest in a crimping part is provided. It is possible to mitigate an increase in the contact pressure at the position where the contact portion is located, and it is possible to further equalize the contact pressure at the caulking portion.
請求項2記載の発明は、請求項1記載の端子圧着電線の製造方法であって、前記芯線部は、前記端子の加締め部に加締められる前の状態で、外周径が前記加締め部を加締めた状態の内周径より大きく設定されることを特徴とする。

It is set to be larger than the inner peripheral diameter in the state where the staking is crimped.
この端子圧着電線では、端子の加締め部に加締められる前の状態で、芯線部の外周径が加締め部を加締めた状態の内周径より大きく設定されているので、芯線部と加締め部との接触を加締め部の全域で確実に行うことができ、芯線部におけるクリープの発生を抑制して加締め部における接触抵抗の増加を抑制することができる。 In this terminal crimped electric wire, the outer peripheral diameter of the core wire portion is set larger than the inner peripheral diameter of the crimped portion in a state before being crimped to the crimped portion of the terminal. The contact with the tightening portion can be reliably performed in the entire area of the crimping portion, and the occurrence of creep in the core wire portion can be suppressed to prevent an increase in contact resistance at the crimping portion.

さらに、加締め部9は、互いの端部を当接して芯線部3を挟み込む一対の狭持部11,13を有し、芯線部3には、一対の狭持部11,13の端部を配置させる凹部15が設けられている。

図3に示すように、端子圧着電線1に導通される端子7は、接触部17と加締め部9とを備えている。接触部17は、筒状に形成された雌型からなり、相手端子である雄型端子(不図示)のタブが挿入されて相手端子と端子7とが電気的に接続される。この接触部17には、加締め部9が一体に設けられている。
As shown in FIG. 3, the terminal 7 that is conducted to the terminal crimping electric wire 1 includes a
加締め部9は、底壁19と一対の狭持部11,13とからなる。底壁19は、接触部17と連続する一部材で形成され、端子7の長手方向に延設されている。この底壁19は、端子圧着電線1の芯線部3の下面側に配置され、幅方向の両側には一対の狭持部11,13が設けられている。

一対の狭持部11,13は、それぞれ底壁19の幅方向の両側に底壁19及び接触部17と連続する一部材で形成されている。この一対の狭持部11,13は、上型と下型とからなる治具(不図示)などによって被覆部5が剥ぎ取られて芯線部3が露出した端子圧着電線1の端末に加締められ、端子7と端子圧着電線1とが電気的に接続される。
The pair of
図1〜図6に示すように、端子圧着電線1は、芯線部3と被覆部5とを備えている。芯線部3は、アルミニウムやアルミニウム合金などの導電性材料の1本の導体からなる。この芯線部3の外周には、被覆部5が一体に設けられている。
As shown in FIGS. 1 to 6, the terminal crimped electric wire 1 includes a
被覆部5は、合成樹脂などの絶縁材料からなり、芯線部3の外周を覆うように芯線部3と一体に設けられている。この被覆部5を剥がすことにより、芯線部3が露出し、この露出した芯線部3に端子7の加締め部9が加締められる。
The covering
このような加締め部9に加締められる芯線部3は、加締め部9に加締められる前の状態で、図5に示すように、一対のフォーミング用金型21,23によって挟み込まれて外周形状が形成される。
As shown in FIG. 5, the
このように形成された図1に示す芯線部3の外周形状は、図2に示すように、芯線部3に加締め部9を加締めたときの加締め部9の内周形状と略同一形状となっている。また、図1の芯線部3の点線は、芯線部3に加締め部9を加締めたときの加締め部9の内周径となっており、芯線部3の外周径は、加締め部9の内周径より大きく設定されている。この大きく設定された芯線部3の外周径は、加締め部9を加締めたときの加工代となっている。さらに、芯線部3の加締め部9を加締めたときの一対の狭持部11,13の端部が位置する部分は、凹部15となっている。

そこで、芯線部3の外周形状を加締め部9を加締めたときの加締め部9の内周形状と略同一形状とすることにより、芯線部3に加締め部9を加締める際の荷重が芯線部3の中心に掛かるようになって、加締め部9における接触圧力が均等化される。また、芯線部3に凹部15を設けることにより、接触圧力が最も高くなる部分Aの接触圧力の上昇を緩和することができる。従って、加締め部9における接触圧力が均等化されるので、芯線部3を加締める加締め部9におけるクリープの発生を抑制して接触圧力が低下する部分が減少され、接触抵抗の増加を抑制することができる。
Therefore, the load when the

The shape of the recess 15 is not limited to the shape shown in FIG. 1 or the like, and may be, for example, the shape of the recess 15a or the
このように構成された端子圧着電線1は、まず、所定位置の被覆部5を剥がして芯線部3を露出させる。次に、露出させた芯線部3に対して、一対のフォーミング用金型21,23で挟んで、芯線部3の外周形状を加締め部9で加締めたときの外周形状と略同一形状に形成すると共に、芯線部3の外周径を加締め部9で加締めたときの外周径より大きく形成させる。そして、この加工された芯線部3に対して、治具などによって芯線部3を外周側から中心側に向けて圧縮するように一対の狭持部11,13を加締め、端子7と端子圧着電線1とを導通させる。
The terminal crimped electric wire 1 configured as described above first peels off the covering
このような端子圧着電線1では、端子7の加締め部9に加締められる前の状態で、芯線部3の外周形状が加締め部9を加締めた状態の内周形状と略同一形状に形成されているので、加締め部9を芯線部3に加締めるときに加締め部9における接触圧力が均等化され、芯線部3におけるクリープの発生を抑制して接触圧力が低下する部分を減少させることができる。

また、芯線部3の外周径は、端子7の加締め部9に加締められる前の状態で、加締め部9を加締めた状態の内周径より大きく設定されているので、芯線部3と加締め部9との接触を加締め部9の全域で確実に行うことができ、芯線部3におけるクリープの発生を抑制して加締め部9における接触抵抗の増加を抑制することができる。
