Abstract

PROBLEM TO BE SOLVED: To provide a terminal metal fitting capable of preventing an electric wire from being dropped off from the terminal metal fitting, and of securing a sufficient strength to a tensile force.SOLUTION: A terminal metal fitting 10 fixed to a terminal part of an electric wire 20 has a wire barrel part 13 wound around and pressure-bonded to the outside of a core wire 21 exposed at the terminal part of the electric wire 20. On a pressure-bonded surface 13P with the core wire 21, of the wire barrel part 13, a plurality of projections 18 and 19 protruded inward from this pressure-bonded surface 13P are provided and arranged in a cross direction to an axis line of the electric wire 20. Due to such a configuration, because the projections 18 and 19 sufficiently bite into the core wire 21 even when a compression degree of the core wire 21 is low, the electric wire 20 can be prevented from being dropped off from the terminal metal fitting 10, and a strength sufficient to the tensile force can be secured.

Description

本発明は、端子金具に関する。   The present invention relates to a terminal fitting.

従来、電線の端末部に固着される端子金具として、電線の端末部において露出された芯線に圧着されるワイヤバレル部を有するものが知られている。ワイヤバレル部は、芯線の外側に巻き付けられて圧着される。   Conventionally, what has a wire barrel part crimped | bonded to the core wire exposed in the terminal part of an electric wire as a terminal metal fitting fixed to the terminal part of an electric wire is known. A wire barrel part is wound around the outer side of a core wire, and is crimped | bonded.

例えば下記特許文献１に記載の端子金具では、ワイヤバレル部のうち芯線との圧着面に、複数の凹部からなるセレーションが形成されている。ワイヤバレル部を芯線に圧着する際、芯線を十分に圧縮して凹部に食い込ませることで、電線が引っ張られて端子金具から抜ける事態を防ぐことができる。   For example, in the terminal fitting described in Patent Document 1 below, serrations including a plurality of recesses are formed on the crimping surface of the wire barrel portion with the core wire. When the wire barrel portion is crimped to the core wire, it is possible to prevent the electric wire from being pulled out of the terminal fitting by sufficiently compressing the core wire and causing it to bite into the recess.

特開２０１０−２７４６３号公報JP 2010-27463 A

しかしながら、芯線の圧縮が不十分である場合には、凹部への食い込みが浅くなり、電線が強く引っ張られると端子金具から抜けてしまう虞がある。一方、芯線の圧縮が十分である場合には、凹部への食い込みは深くなるけれども、芯線が軸方向に延びてその断面が小さくなり、引張力に対して強度不足を招く虞がある。このため、端子金具から電線が抜けることを防ぎつつ、引張力に対して十分な強度を確保することは困難であった。   However, when the core wire is not sufficiently compressed, the recesses are not deeply entrapped, and if the electric wire is pulled strongly, it may come out of the terminal fitting. On the other hand, when the core wire is sufficiently compressed, although the bite into the recess becomes deeper, the core wire extends in the axial direction and its cross section becomes smaller, which may cause insufficient strength against the tensile force. For this reason, it was difficult to ensure sufficient strength against the tensile force while preventing the electric wire from coming off from the terminal fitting.

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、端子金具から電線が抜けることを防ぐことができ、かつ引張力に対して十分な強度を確保することが可能な端子金具を提供することを目的とする。   The present invention has been completed based on the above circumstances, and can prevent a wire from coming out of the terminal fitting and can ensure sufficient strength against a tensile force. The purpose is to provide.

本発明の端子金具は、電線の端末部に固着される端子金具であり、前記電線の端末部において露出された芯線の外側に巻き付けられて圧着されるワイヤバレル部を有し、前記ワイヤバレル部のうち前記芯線との圧着面には、この圧着面よりも内側に突出する突起が、前記電線の軸線に対して交差方向に複数並んで設けられているものである。
このような構成によれば、芯線の圧縮程度が小さくても突起が芯線に十分に食い込むから、端子金具から電線が抜けることを防ぐことができ、かつ引張力に対して十分な強度を確保することができる。 The terminal fitting of the present invention is a terminal fitting fixed to a terminal portion of an electric wire, and has a wire barrel portion that is wound around and crimped to the outside of a core wire exposed at the terminal portion of the electric wire, and the wire barrel portion Among them, a plurality of protrusions protruding inward from the crimping surface are provided on the crimping surface with the core wire in a crossing direction with respect to the axis of the electric wire.
According to such a configuration, even if the degree of compression of the core wire is small, since the protrusion sufficiently bites into the core wire, it is possible to prevent the electric wire from coming out of the terminal fitting and to secure sufficient strength against the tensile force. be able to.

また、前記突起は、その突出端が前記電線の軸方向における一方の側に向くものと、他方の側に向くものとを有しているものとしてもよい。
このような構成によれば、電線が押し込まれても引っ張られても突起の突出端が引っ掛かるため、電線が、その軸方向のいずれの方向にも抜けることを防ぐことができる。 Moreover, the said protrusion is good also as what has the protrusion end which faces the one side in the axial direction of the said electric wire, and a thing which faces the other side.
According to such a configuration, since the protruding end of the protrusion is caught regardless of whether the electric wire is pushed in or pulled, it is possible to prevent the electric wire from being pulled out in any axial direction.

また、前記交差方向に複数並んで設けられた前記突起の列が、前記電線の軸方向に複数列設けられており、一の前記突起の列と他の前記突起の列とでは、前記突起の位置が前記交差方向にずれるように配置されているものとしてもよい。
このような構成によれば、突起が、芯線の周方向に一様に引っ掛かるから、端子金具から電線が抜けることを確実に防ぐことができる。 In addition, a plurality of rows of protrusions provided side by side in the intersecting direction are provided in the axial direction of the electric wire, and one protrusion row and another protrusion row include It is good also as what is arrange | positioned so that a position may shift | deviate to the said cross direction.
According to such a configuration, since the protrusion is uniformly hooked in the circumferential direction of the core wire, it is possible to reliably prevent the electric wire from coming off from the terminal fitting.

また、前記突起の突出端は、鋭角をなして尖っているものとしてもよい。
このような構成によれば、突起の突出端が鈍角である場合に比して芯線に食い込みやすいため、芯線の圧縮程度が小さくてもより十分に芯線に食い込ませることができる。 The protruding end of the protrusion may be sharpened with an acute angle.
According to such a structure, since it is easy to bite into a core wire compared with the case where the protrusion end of a protrusion is an obtuse angle, even if the compression degree of a core wire is small, it can be made to bite into a core wire more fully.

本発明によれば、端子金具から電線が抜けることを防ぐことができ、かつ引張力に対して十分な強度を確保することが可能な端子金具を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the terminal metal fitting which can prevent that an electric wire pulls out from a terminal metal fitting, and can ensure sufficient intensity | strength with respect to a tensile force can be provided.

次に、電線２０の端末部に端子金具１０を固着して、端子金具付き電線を製造する方法の一例を説明する。
まず、電線２０の端末部において被覆２２を皮剥ぎし、芯線２１を露出させる。
次に、電線２０の端末部を端子金具１０の固着部１２の上に配置する。露出した芯線２１をワイヤバレル部１３の圧着面１３Ｐに配置し、被覆２２の端末部をインシュレーションバレル部１４の圧着面に配置する。 Next, an example of a method for manufacturing the electric wire with the terminal fitting by fixing the terminal fitting 10 to the terminal portion of the electric wire 20 will be described.
First, the coating 22 is peeled off at the terminal portion of the electric wire 20 to expose the core wire 21.
Next, the terminal portion of the electric wire 20 is disposed on the fixing portion 12 of the terminal fitting 10. The exposed core wire 21 is disposed on the crimping surface 13P of the wire barrel portion 13, and the terminal portion of the covering 22 is disposed on the crimping surface of the insulation barrel portion 14.

次いで、電線２０の端末部に端子金具１０の固着部１２を圧着する。ワイヤバレル部１３のかしめ片１３Ｋおよびインシュレーションバレル部１４のかしめ片１４Ｋを、芯線２１および被覆２２に巻き付けるようにしてかしめ付ける。すると、ワイヤバレル部１３の圧着面１３Ｐに突設された第１突起１８および第２突起１９が芯線２１に食い込む。このとき、第１突起１８および第２突起１９は、凹部に比して芯線２１に食い込みやすいから、芯線２１を大きく圧縮しなくても芯線２１に十分深く食い込む。そして、第１突起１８および第２突起１９が芯線２１に食い込むことにより、芯線２１の酸化被膜が破断されて剥離され、現れた芯線２１の新生面とワイヤバレル部１３の圧着面１３Ｐとが凝着する。
以上により、ワイヤバレル部１３およびインシュレーションバレル部１４が芯線２１および被覆２２にそれぞれ固着され、端子金具付き電線の製造作業が完了する。 Next, the fixing portion 12 of the terminal fitting 10 is crimped to the terminal portion of the electric wire 20. The caulking piece 13K of the wire barrel portion 13 and the caulking piece 14K of the insulation barrel portion 14 are caulked so as to be wound around the core wire 21 and the covering 22. Then, the first protrusion 18 and the second protrusion 19 that protrude from the crimping surface 13 </ b> P of the wire barrel portion 13 bite into the core wire 21. At this time, the first protrusion 18 and the second protrusion 19 are easy to bite into the core wire 21 as compared with the concave portion, so that the first protrusion 18 and the second protrusion 19 bite into the core wire 21 sufficiently deeply without being greatly compressed. Then, when the first protrusion 18 and the second protrusion 19 bite into the core wire 21, the oxide film of the core wire 21 is broken and peeled off, and the newly formed surface of the core wire 21 and the crimping surface 13 </ b> P of the wire barrel portion 13 are adhered. To do.
By the above, the wire barrel part 13 and the insulation barrel part 14 are each fixed to the core wire 21 and the coating | cover 22, and the manufacture operation | work of the electric wire with a terminal metal fitting is completed.

上記のように構成された本実施形態によれば、以下の効果を奏する。
本実施形態の端子金具１０は、電線２０の端末部に固着される端子金具であり、電線２０の端末部において露出された芯線２１の外側に巻き付けられて圧着されるワイヤバレル部１３を有し、ワイヤバレル部１３のうち芯線２１との圧着面１３Ｐには、この圧着面１３Ｐよりも内側に突出する第１突起１８および第２突起１９が、電線２０の軸線に対して交差方向に複数並んで設けられている。 According to the present embodiment configured as described above, the following effects can be obtained.
The terminal fitting 10 of this embodiment is a terminal fitting fixed to the terminal portion of the electric wire 20, and has a wire barrel portion 13 that is wound around and crimped to the outside of the core wire 21 exposed at the terminal portion of the electric wire 20. A plurality of first projections 18 and second projections 19 projecting inward from the crimping surface 13P are arranged in a crossing direction with respect to the axis of the electric wire 20 on the crimping surface 13P of the wire barrel portion 13 with the core wire 21. Is provided.

これにより、芯線２１の圧縮程度が小さくても第１突起１８および第２突起１９が芯線２１に十分に食い込むため、端子金具１０から電線２０が抜けることを防ぐことができ、かつ引張力に対して十分な強度を確保することができる。
また、アルミ電線は、銅電線等と比較すると、皮剥きにより芯線２１が露出されたときに外気に晒されて芯線２１の表面に酸化被膜ができやすく、芯線２１とワイヤバレル部１３との間に酸化被膜が介在した状態で端子金具１０が圧着されると、電気抵抗が大きくなるという問題がある。しかし、本実施形態の端子金具１０によれば、第１突起１８および第２突起１９が芯線２１に食い込むことにより、酸化被膜が剥離されて現れた芯線２１の新生面とワイヤバレル部１３の圧着面１３Ｐとが凝着するため、電線２０と端子金具１０との間の電気抵抗を小さくして電気的性能の向上を図ることができ、特に有利である。 Accordingly, even if the degree of compression of the core wire 21 is small, the first protrusion 18 and the second protrusion 19 sufficiently bite into the core wire 21, so that the electric wire 20 can be prevented from coming off from the terminal fitting 10 and the tensile force can be reduced. And sufficient strength can be secured.
Moreover, compared with a copper electric wire etc., an aluminum electric wire is easy to be exposed to external air when the core wire 21 is exposed by peeling and an oxide film is formed on the surface of the core wire 21, and between the core wire 21 and the wire barrel portion 13. When the terminal fitting 10 is crimped with the oxide film interposed between the two, there is a problem that the electrical resistance increases. However, according to the terminal fitting 10 of this embodiment, the first protrusion 18 and the second protrusion 19 bite into the core wire 21, so that the new surface of the core wire 21 that appears after the oxide film is peeled off and the crimping surface of the wire barrel portion 13. Since 13P adheres, the electrical performance between the electric wire 20 and the terminal fitting 10 can be reduced to improve the electrical performance, which is particularly advantageous.

また、第１突起１８は、その突出端１７が電線２０の軸方向における前側を向くものであり、第２突起１９は、後側を向くものである。これにより、電線２０が前方に押された場合には、主に第２突起１９の突出端１７が引っ掛かり、電線２０が後方に引っ張られた場合には、主に第１突起１８の突出端１７が引っ掛かる。したがって、電線２０が、前後方向のいずれにも抜けることを防ぐことができる。   Moreover, the 1st protrusion 18 is what the protrusion end 17 faces the front side in the axial direction of the electric wire 20, and the 2nd protrusion 19 faces the back side. Thereby, when the electric wire 20 is pushed forward, the projecting end 17 of the second protrusion 19 is mainly caught, and when the electric wire 20 is pulled rearward, the projecting end 17 of the first protrusion 18 is mainly used. Is caught. Therefore, the electric wire 20 can be prevented from being pulled out in any of the front and rear directions.

また、左右方向に複数並んで設けられた第１突起１８および第２突起１９の列１８Ｌ，１９Ｌが、電線２０の軸方向に複数列設けられており、一の第１突起列１８Ｌまたは第２突起列１９Ｌと、他の第１突起列１８Ｌまたは第２突起列１９Ｌとでは、第１突起１８または第２突起１９の位置が左右方向にずれるように配置されている。これにより、前後方向に第１突起１８または第２突起１９が存在しないラインをなくすことができ、第１突起１８および第２突起１９が、芯線２１の周方向に一様に引っ掛かるから、端子金具１０から電線２０が抜けることをより確実に防ぐことができる。   A plurality of rows 18L, 19L of the first projections 18 and the second projections 19 provided side by side in the left-right direction are provided in the axial direction of the electric wire 20, and the first projection row 18L or the second row The protrusion row 19L and the other first protrusion row 18L or the second protrusion row 19L are arranged such that the positions of the first protrusion 18 or the second protrusion 19 are shifted in the left-right direction. As a result, a line in which the first protrusion 18 or the second protrusion 19 does not exist in the front-rear direction can be eliminated, and the first protrusion 18 and the second protrusion 19 are uniformly hooked in the circumferential direction of the core wire 21. It can prevent more reliably that the electric wire 20 pulls out from 10.

また、第１突起１８および第２突起１９の突出端１７は、鋭角をなして尖っている。これにより、例えば突起の突出端が鈍角である場合に比して芯線２１に食い込みやすいため、芯線２１の圧縮程度が小さくてもより十分に芯線２１に食い込ませることができる。   The protruding ends 17 of the first protrusion 18 and the second protrusion 19 are sharpened at an acute angle. Thereby, for example, since it is easy to bite into the core wire 21 as compared with the case where the protruding end of the protrusion has an obtuse angle, even if the degree of compression of the core wire 21 is small, the core wire 21 can be bite more sufficiently.
