これに関連する従来の端子機構が特許文献１に記載されている。
特許文献１に記載された端子機構は、図１７に示すように、縦向き平板状の雄端子１０１と、その雄端子１０１が一定方向から差し込まれるように構成された複数組の弾性板部１０３，１０４を備える雌端子１０５（図１５、図１６参照）とを備えている。
雌端子１０５の弾性板部１０３，１０４は、図１６、図１７に示すように、雄端子１０１の差し込み中心位置ＣＬに対して左右対称に形成されて、その弾性板部１０３，１０４の先端位置（後端位置）に形成された接触部１０３ｃ，１０４ｃが雄端子１０１の両側面に接触するように構成されている。さらに、前記雌端子１０５が雄端子１０１の差し込み方向に二セット並んで設置されている。
このように、雌端子１０５が雄端子１０１の差し込み方向に二セット並べて設けられていることで、雄端子１０１と雌端子１０５との接触部分が増加して、一つの接触部分に流れる電流を減少させることができる。このため、端子の磨耗等を抑制でき、寿命延長を図ることができる。 A related terminal mechanism related to this is described in Patent Document 1.

特開２００１−０５７２０４号公報JP 2001-057204 A

しかし、雌端子１０５を雄端子１０１の差し込み方向に二セット並べて設ける構成では、雄端子１０１を差し込み方向に長く形成する必要がある。このため、雄端子１０１が大型化する。また、二セットの雌端子１０５を雄端子１０１の差し込み方向に並べて設置するため、その雌端子１０５の設置スペースも広く必要になる。   However, in the configuration in which two sets of female terminals 105 are provided side by side in the insertion direction of the male terminals 101, the male terminals 101 need to be formed long in the insertion direction. For this reason, the male terminal 101 is increased in size. Further, since the two sets of female terminals 105 are installed side by side in the insertion direction of the male terminals 101, a large installation space for the female terminals 105 is required.

本発明は、上記問題点を解決するためになされたものであり、本発明が解決しようとする課題は、雄端子と雌端子との接触部分を増加させて前記接触部分を流れる電流を減少させるともに、雄端子の大型化、及び雌端子の設置スペースの増加を抑制することである。   The present invention has been made to solve the above-described problems, and the problem to be solved by the present invention is to increase the contact portion between the male terminal and the female terminal and reduce the current flowing through the contact portion. Both are to suppress the increase in the size of the male terminal and the increase in the installation space for the female terminal.

上記した課題は、各請求項の発明によって解決される。
請求項１の発明は、雄端子と、少なくとも一組の弾性板部を備える雌端子とを備え、前記雄端子が前記雌端子の少なくとも一組の弾性板部間に一定方向から差し込まれて、前記雄端子の両側面がそれらの弾性板部の弾性力により幅方向両側から押圧されることで、前記雄端子と前記雌端子とが電気的に接続される構成の端子機構であって、前記雌端子は、前記少なくとも一組の弾性板部とは異なる方向に弾性変形が可能な別の弾性板部とを備えており、前記別の弾性板部が前記雄端子の両側面以外の面を押圧できるように構成されていることを特徴とする。 The above-described problems are solved by the inventions of the claims.
The invention of claim 1 includes a male terminal and a female terminal having at least one set of elastic plate portions, and the male terminal is inserted between at least one set of elastic plate portions of the female terminal from a certain direction, The male terminal and the female terminal are electrically connected to each other by pressing both side surfaces of the male terminal from both sides in the width direction by the elastic force of the elastic plate portion, The female terminal includes another elastic plate portion that can be elastically deformed in a direction different from the at least one pair of elastic plate portions, and the other elastic plate portion has a surface other than both side surfaces of the male terminal. It is comprised so that it can press.

本発明によると、雄端子が雌端子の少なくとも一組の弾性板部（以下、組用の弾性板部という）間に一定方向から差し込まれる際、即ち、雄端子が組用の弾性板部によって両側面を押圧される際に、両側面以外の面が別の弾性板部によって押圧されるようになる。このように、別の弾性板部によって雄端子と雌端子との接触部分を増やすことができるため、一つの接触部分に流れる電流を減少させることができ、端子の寿命延長を図ることができる。
また、雄端子の両側面を雌端子の組用の弾性板部によって押圧し、雄端子の両側面以外の面を別の弾性板部によって押圧する構成のため、組用の弾性板部と別の弾性板部とを雄端子の差し込み方向においてほぼ同位置に配置することができる。即ち、雌端子の組用の弾性板部と別の弾性板部とを雄端子の差し込み方向に並べて設ける必要がなくなる。このため、雌端子が雄端子の差し込み方向に長くならず、雌端子の設置スペースの増加を抑制できる。また、雌端子が雄端子の差し込み方向に長くならないため、雄端子も差し込み方向に長く製作する必要がなくなる。 According to the present invention, when the male terminal is inserted from a certain direction between at least one set of elastic plate portions of the female terminal (hereinafter referred to as an elastic plate portion for assembly), that is, the male terminal is inserted by the elastic plate portion for assembly. When both side surfaces are pressed, surfaces other than the both side surfaces are pressed by another elastic plate portion. Thus, since the contact part of a male terminal and a female terminal can be increased by another elastic board part, the electric current which flows into one contact part can be decreased, and the lifetime of a terminal can be aimed at.
In addition, because both the side surfaces of the male terminal are pressed by the elastic plate portion for assembly of the female terminal and the surfaces other than the both side surfaces of the male terminal are pressed by another elastic plate portion, it is separated from the elastic plate portion for assembly. The elastic plate portion can be disposed at substantially the same position in the insertion direction of the male terminal. That is, it is not necessary to provide the elastic plate part for the assembly of the female terminals and another elastic plate part in the male terminal insertion direction. For this reason, a female terminal does not become long in the insertion direction of a male terminal, and can suppress the increase in the installation space of a female terminal. Further, since the female terminal does not become long in the insertion direction of the male terminal, it is not necessary to make the male terminal long in the insertion direction.

請求項２の発明によると、別の弾性板部は、雄端子の下面を下方から押圧できるように構成されている。
このため、別の弾性板部が雄端子の差し込みを妨げることがない。これにより、別の弾性板部を雄端子の差し込み方向に複数設けることが可能になる。
請求項３の発明によると、別の弾性板部は複数設けられていることを特徴とする。 According to invention of Claim 2, another elastic board part is comprised so that the lower surface of a male terminal can be pressed from the downward direction.
For this reason, another elastic board part does not prevent insertion of a male terminal. As a result, a plurality of other elastic plate portions can be provided in the insertion direction of the male terminal.
The invention according to claim 3 is characterized in that a plurality of other elastic plate portions are provided.

請求項４の発明によると、雌端子は、雄端子の差し込み方向に複数設けられていることを特徴とする。
このため、雄端子と雌端子との接触部分をさらに増やすことができ、一つの接触部分に流れる電流をさらに減少させることができる。さらに、雄端子と雌端子との接続信頼性を向上できる。
請求項５の発明によると、雄端子と雌端子とは、電力用端子、あるいは信号用端子であることを特徴とする。 According to the invention of claim 4, a plurality of female terminals are provided in the insertion direction of the male terminals.
For this reason, the contact part of a male terminal and a female terminal can be increased further, and the electric current which flows into one contact part can further be reduced. Further, the connection reliability between the male terminal and the female terminal can be improved.
According to the invention of claim 5, the male terminal and the female terminal are power terminals or signal terminals.

請求項６の発明によると、雄端子は電動工具に設けられており、雌端子はバッテリパックに設けられていることを特徴とする。
請求項７の発明によると、雄端子はバッテリパックに設けられており、雌端子は電動工具に設けられていることを特徴とする。
請求項８の発明によると、雄端子は充電器に設けられており、雌端子はバッテリパックに設けられていることを特徴とする。
請求項９の発明によると、雄端子はバッテリパックに設けられており、雌端子は充電器に設けられていることを特徴とする。 According to the invention of claim 6, the male terminal is provided in the electric tool, and the female terminal is provided in the battery pack.
According to the invention of claim 7, the male terminal is provided in the battery pack, and the female terminal is provided in the electric tool.
According to the invention of claim 8, the male terminal is provided in the charger, and the female terminal is provided in the battery pack.
According to the invention of claim 9, the male terminal is provided in the battery pack, and the female terminal is provided in the charger.

本発明によると、雄端子と雌端子との接触部分を増加させることができるため、一つの接触部分に流れる電流が減少し、端子の寿命延長が図れる。また、雄端子と雌端子との接触部分が増加しても、雄端子の大型化、及び雌端子の設置スペースの増加を抑制できる。   According to the present invention, since the contact portion between the male terminal and the female terminal can be increased, the current flowing through one contact portion is reduced, and the life of the terminal can be extended. Moreover, even if the contact part of a male terminal and a female terminal increases, the enlargement of a male terminal and the increase in the installation space of a female terminal can be suppressed.

＜本実施形態に係る端子機構５０の長所について＞
本実施形態に係る端子機構５０によると、電源用雄端子５５が電源用雌端子６２の二組の弾性板部６５間に一定方向から差し込まれる際、即ち、電源用雄端子５５が二組の弾性板部６５によって両側面を押圧される際に、その電源用雄端子５５の下面が下側弾性板部６７によって押圧されるようになる。このように、下側弾性板部６７（別の弾性板部）によって電源用雄端子５５と電源用雌端子６２との接触部分を増やすことができるため、一つの接触部分に流れる電流を減少させることができ、端子機構５０の寿命延長を図ることができる。
また、電源用雄端子５５の両側面を電源用雌端子６２の二組の弾性板部６５によって押圧し、電源用雄端子５５の下面を下側弾性板部６７（別の弾性板部）によって押圧する構成のため、二組の弾性板部６５と下側弾性板部６７を電源用雄端子５５の差し込み方向においてほぼ同位置に配置することができる。即ち、電源用雌端子６２の二組の弾性板部６５と下側弾性板部６７とを電源用雄端子５５の差し込み方向に並べて設ける必要がなくなる。このため、電源用雌端子６２が電源用雄端子５５の差し込み方向に長くならず、電源用雌端子６２の設置スペースの増加を抑制できる。また、電源用雌端子６２が電源用雄端子５５の差し込み方向に長くならないため、電源用雄端子５５も差し込み方向に長く製作する必要がなくなる。 <Advantages of the terminal mechanism 50 according to the present embodiment>
According to the terminal mechanism 50 according to the present embodiment, when the power male terminal 55 is inserted between the two elastic plate portions 65 of the power female terminal 62 from a certain direction, that is, two power male terminals 55 are provided. When both side surfaces are pressed by the elastic plate portion 65, the lower surface of the power male terminal 55 is pressed by the lower elastic plate portion 67. As described above, the lower elastic plate portion 67 (another elastic plate portion) can increase the contact portion between the power male terminal 55 and the power female terminal 62, thereby reducing the current flowing through one contact portion. Thus, the service life of the terminal mechanism 50 can be extended.
Further, both side surfaces of the power supply male terminal 55 are pressed by two sets of elastic plate portions 65 of the power supply female terminal 62, and the lower surface of the power supply male terminal 55 is pressed by the lower elastic plate portion 67 (another elastic plate portion). Because of the pressing configuration, the two elastic plate portions 65 and the lower elastic plate portion 67 can be arranged at substantially the same position in the insertion direction of the power male terminal 55. That is, it is not necessary to provide two sets of the elastic plate portions 65 and the lower elastic plate portion 67 of the power supply female terminal 62 side by side in the insertion direction of the power supply male terminal 55. For this reason, the female terminal 62 for power supply does not become long in the insertion direction of the male terminal 55 for power supply, and the increase in the installation space of the female terminal 62 for power supply can be suppressed. Further, since the power supply female terminal 62 does not become long in the insertion direction of the power supply male terminal 55, it is not necessary to make the power supply male terminal 55 long in the insertion direction.

また、本実施形態では、図６等に示すように、電源用雌端子６２のベース部６２ｂに一個の下側弾性板部６７を設ける例を示したが、図１０、図１１に示すように、下側弾性板部６７を電源用雄端子５５の差し込み方向に二個設けることも可能である。
このようにすることで、電源用雄端子５５と電源用雌端子６２との接触部位をさらに増やすことができ、端子機構５０の寿命延長、及び接続信頼性を向上させることができる。 <Example of change>
