図１に示すように、本実施形態に係る圧着端子１０は、電線１に接続されて端子付き電線１００を構成する。 As shown in FIG. 1, the crimp terminal 10 according to the present embodiment is connected to the electric wire 1 to form the electric wire 100 with a terminal.

電線１は、導体２と、この導体２の周囲を覆う外被３とを有している。導体２は、アルミニウムまたはアルミニウム合金からなる複数の素線４を束ねて構成されている。外被３は、可撓性及び絶縁性を有する樹脂材料から形成されている。電線１は、その端部において、外被３が除去されて導体２の一部が露出している。なお、電線１としては、銅または銅合金からなる素線４を束ねた導体２を有したものでもよく、素線４に錫メッキが施されていてもよい。 The electric wire 1 has a conductor 2 and an outer cover 3 that covers the periphery of the conductor 2. The conductor 2 is formed by bundling a plurality of strands 4 made of aluminum or an aluminum alloy. The jacket 3 is formed of a flexible and insulating resin material. At the end of the electric wire 1, the outer cover 3 is removed and a part of the conductor 2 is exposed. The electric wire 1 may have a conductor 2 in which a wire 4 made of copper or a copper alloy is bundled, or the wire 4 may be tin-plated.

圧着端子１０は、銅、銅合金、アルミニウムあるいはアルミニウム合金等の導電性金属材料からなる板材に対して、例えば、プレス加工することにより形成されたもので、電線接続部１１を有している。電線接続部１１の先端側には、接続相手に接続される端子部１２が形成されている。 The crimp terminal 10 is formed by, for example, pressing a plate material made of a conductive metal material such as copper, a copper alloy, aluminum, or an aluminum alloy, and has an electric wire connecting portion 11. A terminal portion 12 connected to a connection partner is formed on the tip end side of the electric wire connecting portion 11.

圧着端子１０の電線接続部１１は、導体圧着部１５と、被覆圧着部１６とを有しており、これらの導体圧着部１５と被覆圧着部１６とは、連結部１７によって連結されている。導体圧着部１５は、一対の導体圧着片１５ａを有しており、被覆圧着部１６は、一対の被覆圧着片１６ａを有している。 The electric wire connecting portion 11 of the crimp terminal 10 has a conductor crimping portion 15 and a covering crimping portion 16, and these conductor crimping portions 15 and the covering crimping portion 16 are connected by a connecting portion 17. The conductor crimping portion 15 has a pair of conductor crimping pieces 15a, and the covering crimping portion 16 has a pair of covering crimping pieces 16a.

電線接続部１１は、導体圧着片１５ａを加締めることで電線１の導体２が導体圧着部１５に圧着固定され、被覆圧着片１６ａを加締めることで電線１の外被３の部分が被覆圧着部１６に圧着固定される。これにより、圧着端子１０と電線１とが接続されて、圧着端子１０と電線１の導体２とが導通された端子付き電線１００となる。 In the electric wire connecting portion 11, the conductor 2 of the electric wire 1 is crimped and fixed to the conductor crimping portion 15 by crimping the conductor crimping piece 15a, and the outer cover 3 portion of the electric wire 1 is coated and crimped by crimping the coated crimping piece 16a. It is crimp-fixed to the portion 16. As a result, the crimp terminal 10 and the electric wire 1 are connected to form an electric wire 100 with a terminal in which the crimp terminal 10 and the conductor 2 of the electric wire 1 are conducted.

図２（ａ）に示すように、圧着端子１０の導体圧着部１５は、その内面側が導体接触面１８となっている。この導体接触面１８は、電線１の導体２に導体圧着部１５が加締められた際に、電線１の導体２の外周面に接触するようになっている。この導体圧着部１５の導体接触面１８には、複数のセレーション２０が形成されている。本例では、３つのセレーション２０が形成されている。セレーション２０は、導体圧着部１５の幅方向に沿って形成されており、導体圧着部１５の軸方向に互いに間隔をあけて配列されている。 As shown in FIG. 2A, the conductor crimping portion 15 of the crimping terminal 10 has a conductor contact surface 18 on the inner surface side thereof. The conductor contact surface 18 comes into contact with the outer peripheral surface of the conductor 2 of the electric wire 1 when the conductor crimping portion 15 is crimped to the conductor 2 of the electric wire 1. A plurality of serrations 20 are formed on the conductor contact surface 18 of the conductor crimping portion 15. In this example, three serrations 20 are formed. The serrations 20 are formed along the width direction of the conductor crimping portion 15, and are arranged at intervals in the axial direction of the conductor crimping portion 15.

図２（ｂ）に示すように、導体接触面１８に形成されたセレーション２０は、第一凹部２１と、第二凹部２２とを有している。第一凹部２１及び第二凹部２２は、それぞれ断面凹状の長尺の溝状に形成されている。第二凹部２２は、第一凹部２１の底部２１ａに形成されており、第一凹部２１の幅方向の略中央位置に形成されている。 As shown in FIG. 2B, the serration 20 formed on the conductor contact surface 18 has a first recess 21 and a second recess 22. The first recess 21 and the second recess 22 are each formed in a long groove shape having a concave cross section. The second recess 22 is formed in the bottom portion 21a of the first recess 21, and is formed at a substantially central position in the width direction of the first recess 21.

次に、この圧着端子１０を電線１の端末部に圧着固定して端子付き電線１００を製造する場合について説明する。
図３は、圧着端子を電線に加締める圧着装置を示す図であって、図３（ａ）は圧着装置の概略正面図、図３（ｂ）は図３（ａ）におけるＢ−Ｂ断面図である。図４は、圧着装置における圧着端子を電線に加締めた状態を示す図であって、図４（ａ）は圧着装置の概略正面図、図４（ｂ）は図４（ａ）におけるＣ−Ｃ断面図である。 Next, a case where the crimp terminal 10 is crimped and fixed to the terminal portion of the electric wire 1 to manufacture the electric wire 100 with a terminal will be described.
3A and 3B are views showing a crimping device for crimping a crimping terminal to an electric wire, FIG. 3A is a schematic front view of the crimping device, and FIG. 3B is a sectional view taken along line BB in FIG. 3A. Is. 4A and 4B are views showing a state in which a crimping terminal in a crimping device is crimped to an electric wire, FIG. 4A is a schematic front view of the crimping device, and FIG. It is a C sectional view.

図３（ａ）及び図３（ｂ）に示すように、圧着端子１０に電線１の端末部を接続する場合には、例えば、圧着装置４０を用いる。この圧着装置４０は、アンビル（下型）４１と、クリンパ（上型）４２とを備えている。クリンパ４２は、昇降可能とされており、アンビル４１に対して相対的に近接及び離間する。クリンパ４２は、導体加締め部４２ａと、被覆加締め部４２ｂとを有している。 As shown in FIGS. 3A and 3B, when connecting the terminal portion of the electric wire 1 to the crimping terminal 10, for example, a crimping device 40 is used. The crimping device 40 includes an anvil (lower type) 41 and a crimper (upper type) 42. The crimper 42 can be raised and lowered, and is relatively close to and separated from the anvil 41. The crimper 42 has a conductor crimping portion 42a and a covering crimping portion 42b.

この圧着装置４０によって圧着端子１０に電線１の端末部を圧着して接続するには、アンビル４１上に配置させた圧着端子１０の上部に、外被３から導体２を露出させた電線１の端末部を載置させる。そして、電線１の導体２を圧着端子１０の導体圧着部１５に配置させるとともに、外被３の端部を圧着端子１０の被覆圧着部１６に配置させる。 In order to crimp and connect the terminal portion of the electric wire 1 to the crimp terminal 10 by the crimping device 40, the electric wire 1 in which the conductor 2 is exposed from the outer cover 3 on the upper part of the crimp terminal 10 arranged on the anvil 41. Place the terminal part. Then, the conductor 2 of the electric wire 1 is arranged in the conductor crimping portion 15 of the crimping terminal 10, and the end portion of the outer cover 3 is arranged in the covering crimping portion 16 of the crimping terminal 10.

図４（ａ）及び図４（ｂ）に示すように、クリンパ４２を下降させると、導体圧着部１５は、クリンパ４２の導体加締め部４２ａによって導体圧着片１５ａが内側に曲げられ、電線１の導体２に加締められる。同様に、被覆圧着部１６は、クリンパ４２の被覆加締め部４２ｂによって被覆圧着片１６ａが内側に曲げられ、電線１の外被３の部分に加締められる。そして、圧着端子１０は、導体２に導体圧着部１５が加締めとともに外被３に被覆圧着部１６が加締められることで、電線１の端末部に接続されて導体２と電気的に接続される。これにより、電線１の端末部に圧着端子１０が接続された端子付き電線１００が得られる。 As shown in FIGS. 4A and 4B, when the crimper 42 is lowered, the conductor crimping piece 15a is bent inward by the conductor crimping portion 42a of the crimper 42, and the electric wire 1 It is crimped to the conductor 2 of. Similarly, in the covering crimping portion 16, the covering crimping piece 16a is bent inward by the covering crimping portion 42b of the crimper 42, and the covering crimping portion 16 is crimped to the outer cover 3 portion of the electric wire 1. Then, the crimp terminal 10 is connected to the terminal portion of the electric wire 1 and electrically connected to the conductor 2 by crimping the conductor crimping portion 15 to the conductor 2 and crimping the covering crimping portion 16 to the outer cover 3. To. As a result, the electric wire 100 with a terminal in which the crimp terminal 10 is connected to the terminal portion of the electric wire 1 can be obtained.

上記のように、電線１の端末部に圧着端子１０を加締める際に、圧着端子１０の導体圧着部１５では、導体接触面１８が導体２の外周面に圧接される。すると、導体２への加締め箇所では、加締められることで電線１の導体２に軸方向へ延びる力が付与される。これにより、導体接触面１８では、各セレーション２０の第一凹部２１及び第二凹部２２のそれぞれの縁部の角が導体２に食い込む。特に、両側のセレーション２０の第一凹部２１及び第二凹部２２では、導体２の延び方向前方側の角が導体２に食い込む。これにより、圧着端子１０と電線１の導体２とが良好に凝着して導通される。例えば、導体２の素線４がアルミニウムまたはアルミニウム合金である場合、素線４の表面の酸化皮膜がセレーション２０の第一凹部２１及び第二凹部２２のそれぞれの縁部の角で破壊される。これにより、圧着端子１０と導体２とが良好に導通され、圧着箇所での電気抵抗が低減される。このようにして得られた端子付き電線１００では、サーマルショック試験においても、電線１の導体２との凝着箇所が破壊されず、良好な導通状態が維持された。 As described above, when the crimp terminal 10 is crimped to the terminal portion of the electric wire 1, the conductor contact surface 18 is pressed against the outer peripheral surface of the conductor 2 at the conductor crimp portion 15 of the crimp terminal 10. Then, at the crimping point on the conductor 2, a force extending in the axial direction is applied to the conductor 2 of the electric wire 1 by being crimped. As a result, on the conductor contact surface 18, the corners of the edges of the first recess 21 and the second recess 22 of each serration 20 bite into the conductor 2. In particular, in the first recess 21 and the second recess 22 of the serrations 20 on both sides, the corner on the front side in the extending direction of the conductor 2 bites into the conductor 2. As a result, the crimp terminal 10 and the conductor 2 of the electric wire 1 are satisfactorily adhered to each other and are conducted. For example, when the wire 4 of the conductor 2 is aluminum or an aluminum alloy, the oxide film on the surface of the wire 4 is broken at the corners of the edges of the first recess 21 and the second recess 22 of the serration 20. As a result, the crimp terminal 10 and the conductor 2 are satisfactorily conducted, and the electric resistance at the crimped portion is reduced. In the electric wire 100 with terminals thus obtained, the adhesion portion of the electric wire 1 to the conductor 2 was not destroyed even in the thermal shock test, and a good conductive state was maintained.

以上、説明したように、本実施形態に係る圧着端子１０によれば、電線１の端末部に導体圧着部１５を加締めることにより、導体圧着部１５における導体接触面１８のセレーション２０を構成する第一凹部２１及び第二凹部２２の各縁部の角を導体２に食い込ませることができる。これにより、導体接触面１８に単に凹状のセレーションを形成した場合と比較し、導体２との凝着面積を十分に確保して圧着箇所での電気抵抗を抑え、良好な導通状態を得ることができる。 As described above, according to the crimp terminal 10 according to the present embodiment, the serration 20 of the conductor contact surface 18 in the conductor crimping portion 15 is formed by crimping the conductor crimping portion 15 to the terminal portion of the electric wire 1. The corners of the edges of the first recess 21 and the second recess 22 can be made to bite into the conductor 2. As a result, as compared with the case where a concave serration is simply formed on the conductor contact surface 18, it is possible to secure a sufficient adhesion area with the conductor 2 to suppress electrical resistance at the crimping point and obtain a good conduction state. it can.

しかも、第一凹部２１が導体圧着部１５における幅方向に延びる溝部からなり、第二凹部２２が第一凹部２１の延在方向に沿って延びる溝部からなる。したがって、電線１の端末部に導体圧着部１５を加締めることで軸方向に延びる力が付与される導体２に、導体圧着部１５の幅方向に延びる第一凹部２１及び第二凹部２２の各縁部の角を略全長にわたって食い込ませることができる。 Moreover, the first recess 21 is composed of a groove extending in the width direction of the conductor crimping portion 15, and the second recess 22 is composed of a groove extending along the extending direction of the first recess 21. Therefore, each of the first recess 21 and the second recess 22 extending in the width direction of the conductor crimping portion 15 is applied to the conductor 2 to which the force extending in the axial direction is applied by crimping the conductor crimping portion 15 to the terminal portion of the electric wire 1. The corners of the edge can be cut into the entire length.

そして、この圧着端子１０が電線１の端末部に接続された端子付き電線１００によれば、電線１の導体２との良好な導通状態が確保された端子付き電線とすることができる。 Then, according to the electric wire 100 with a terminal in which the crimp terminal 10 is connected to the terminal portion of the electric wire 1, it is possible to obtain an electric wire with a terminal in which a good conduction state with the conductor 2 of the electric wire 1 is ensured.
