Description

端子接続構造Terminal connection structure
　本発明は、バネ接触部の弾性復帰力を接触荷重としてタブ端子部とバネ接触部間が電気的に接続される端子接続構造に関する。 The present invention relates to a terminal connection structure in which a tab terminal portion and a spring contact portion are electrically connected using an elastic return force of a spring contact portion as a contact load.
　この種の従来の端子接続構造として、図１及び図２に示すものがある（類似技術として特許文献１参照）。この端子接続構造１００は、タブ端子部１０２を有するオス端子１０１と、バネ接触部１１２を有するメス端子１１０とを備えている。タブ端子部１０２は、フラットな平板状である。メス端子１１０は、筒部１１１内にバネ接触部１１２を有し、このバネ接触部１１２に半球面突状の接点部（インデント部）１１３が設けられている。 There is a conventional terminal connection structure of this type as shown in FIGS. 1 and 2 (refer to Patent Document 1 as a similar technique). The terminal connection structure 100 includes a male terminal 101 having a tab terminal portion 102 and a female terminal 110 having a spring contact portion 112. The tab terminal portion 102 has a flat plate shape. The female terminal 110 has a spring contact portion 112 in a cylindrical portion 111, and a hemispherical protruding contact portion (indent portion) 113 is provided on the spring contact portion 112.
　図１の状態にあって、オス端子１０１のタブ端子部１０２をメス端子１１０の筒部１１１内に挿入すると、タブ端子部１０２がバネ接触部１１２と接触し、バネ接触部１１２が押圧されて図２の矢印方向へ弾性変形する。これにより、端子接続構造１００は、タブ端子部１０２の筒部１１１内への挿入が許容され、図２の状態となる。筒部１１１内に挿入されたタブ端子部１０２は、バネ接触部１１２の弾性復帰力を接触荷重としてバネ接触部１１２及び筒部１１１の上面に電気的に接続される。バネ接触部１１２とタブ端子部１０２の間は、小さい面積である接点部１１３を介して接触するため、強い接触荷重をもって接触される。 In the state of FIG. 1, when the tab terminal portion 102 of the male terminal 101 is inserted into the cylindrical portion 111 of the female terminal 110, the tab terminal portion 102 comes into contact with the spring contact portion 112 and the spring contact portion 112 is pressed. Elastically deforms in the direction of the arrow in FIG. As a result, the terminal connection structure 100 is allowed to be inserted into the cylindrical portion 111 of the tab terminal portion 102 and is in the state of FIG. The tab terminal portion 102 inserted into the tube portion 111 is electrically connected to the spring contact portion 112 and the upper surface of the tube portion 111 using the elastic return force of the spring contact portion 112 as a contact load. Since the spring contact part 112 and the tab terminal part 102 are contacted via the contact part 113 which is a small area, they are contacted with a strong contact load.

　ところで、前記従来の端子接続構造１００では、例えば端子挿入過程や端子離脱過程にあって、タブ端子部１０２が微摺動すると、酸化摩耗粉が発生する。ここで、微摺動時における挿入方向の移動と離脱方向の移動では接点部１１３が同じ軌跡上を移動する。このため、酸化摩耗粉が１箇所に溜まり易く、摺動回数が増す毎に酸化摩耗粉が大きく成長する。大きく成長した酸化摩耗粉がバネ接触部１１２の接点部１１３とタブ端子部１０２の間に介在すると、接触箇所の電気抵抗が増大することになる。 By the way, in the conventional terminal connection structure 100, for example, in the terminal insertion process or the terminal removal process, when the tab terminal portion 102 slides slightly, oxidized wear powder is generated. Here, the contact portion 113 moves on the same locus in the movement in the insertion direction and the movement in the separation direction at the time of fine sliding. For this reason, the oxidized wear powder tends to accumulate in one place, and the oxidized wear powder grows greatly every time the number of sliding increases. When the greatly grown oxidized wear powder is interposed between the contact portion 113 of the spring contact portion 112 and the tab terminal portion 102, the electrical resistance at the contact location increases.
　そこで、本発明は、前記した課題を解決すべくなされたものであり、酸化摩耗粉がバネ接触部とタブ端子部の間に介在することに起因する電気抵抗の増大を極力防止できる端子接続構造を提供することを目的とする。 Therefore, the present invention has been made to solve the above-described problems, and a terminal connection structure that can prevent an increase in electrical resistance caused by the presence of oxidized wear powder between the spring contact portion and the tab terminal portion as much as possible. The purpose is to provide.
　本発明の要旨は、次の通りである。タブ端子部を有するオス端子と、筒部内に配置されたバネ接触部を有するメス端子と、タブ端子部が筒部内に挿入され、バネ接触部の弾性復帰力を接触荷重としてタブ端子部とバネ接触部間が電気的に接続される端子接続構造であって、タブ端子部には、突状の接点部が設けられ、バネ接触部には、タブ端子部の挿入・離脱方向に対し斜め方向に延びる摺動ガイド突部が設けられ、タブ端子部の挿入方向の移動では、接点部が摺動ガイド突部の一方の側面に沿って摺動し、タブ端子部の離脱方向の移動では、接点部が摺動ガイド突部の他方の側面に沿って摺動することを特徴とする端子接続構造。 The gist of the present invention is as follows. A male terminal having a tab terminal part, a female terminal having a spring contact part arranged in the cylinder part, a tab terminal part is inserted into the cylinder part, and the elastic return force of the spring contact part is used as a contact load and the tab terminal part and the spring A terminal connection structure in which the contact portions are electrically connected. The tab terminal portion is provided with a protruding contact portion, and the spring contact portion is inclined with respect to the insertion / removal direction of the tab terminal portion. In the movement of the tab terminal portion in the insertion direction, the contact portion slides along one side surface of the sliding guide projection, and in the movement of the tab terminal portion in the separation direction, A terminal connection structure, wherein the contact portion slides along the other side surface of the sliding guide projection.
　摺動ガイド突部は、細長いストレートな突壁であるものであってもよい。 The sliding guide protrusion may be an elongated straight protrusion wall.
　本発明によれば、タブ端子部が微摺動すると、挿入方向の移動と離脱方向の移動ではタブ端子部の接点部がバネ接触部上の異なる軌跡上を移動する。このため、酸化摩耗粉が１箇所に溜まり難く、摺動回数が増しても酸化摩耗粉が大きく成長することを抑制できる。従って、酸化摩耗粉がバネ接触部とタブ端子部の間に介在することに起因する電気抵抗の増大を極力防止できる。 According to the present invention, when the tab terminal portion slides slightly, the contact portion of the tab terminal portion moves on different tracks on the spring contact portion in the movement in the insertion direction and the movement in the separation direction. For this reason, it is difficult for the oxidized wear powder to accumulate in one place, and it is possible to suppress the oxidized wear powder from growing greatly even if the number of sliding times increases. Accordingly, it is possible to prevent an increase in electrical resistance due to the presence of oxidized wear powder between the spring contact portion and the tab terminal portion as much as possible.

　上記構成において、図４の状態にあって、オス端子２のタブ端子部３を筒部１１内に挿入すると、タブ端子部３がバネ接触部１２と接触し、バネ接触部１２が押圧されて図５の矢印方向へ弾性変形する。これにより、タブ端子部３は、筒部１１内の奥への挿入が許容され、図５の挿入完了位置まで挿入される。バネ接触部１２とタブ端子部３の間は、小さい面積である接点部５を介して接触するため、強い接触荷重をもって接触される。 In the above configuration, in the state of FIG. 4, when the tab terminal portion 3 of the male terminal 2 is inserted into the cylindrical portion 11, the tab terminal portion 3 comes into contact with the spring contact portion 12, and the spring contact portion 12 is pressed. Elastically deforms in the direction of the arrow in FIG. Thereby, the tab terminal portion 3 is allowed to be inserted into the tube portion 11 and inserted to the insertion completion position in FIG. Since the spring contact part 12 and the tab terminal part 3 are contacted via the contact part 5 which is a small area, they are contacted with a strong contact load.
　図５の端子接続状態にあって、オス端子２をメス端子１０の筒部１１より引き抜くと、タブ端子部３が離脱方向ＲＤに移動して筒部１１より引き抜かれる。 5, when the male terminal 2 is pulled out from the cylindrical portion 11 of the female terminal 10, the tab terminal portion 3 moves in the detaching direction RD and is pulled out from the cylindrical portion 11.
　例えば、端子挿入過程や端子離脱過程にあって、タブ端子部３に微摺動が発生する場合がある。ここで、図４（ｃ）に示すように、微摺動時におけるタブ端子部３の端子挿入方向ＩＤの移動では、その接点部５がバネ接触部１２の摺動ガイド突部１７に当接する。そして接点部５は、摺動ガイド突部１７にガイドされ、摺動ガイド突部１７の一方の側面に沿って移動（図４（ｃ）のａ軌跡）する。接点部５が摺動ガイド突部１７の終端部１７ｂの位置を超えると、摺動ガイド突部１７のガイド規制が解除される。接点部５は、それ以降、摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図４（ｃ）のａ１軌跡）する。又、接点部５が摺動ガイド突部１７の終端部１７ｂの手前位置で摺動ガイド突部１７の傾斜を乗り越えると、その時点で摺動ガイド突部１７のガイド規制が解除される。接点部５は、それ以降、摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図４（ｃ）のａ２軌跡）する。 For example, in the terminal insertion process or the terminal removal process, the tab terminal portion 3 may be slightly slid. Here, as shown in FIG. 4C, when the tab terminal portion 3 moves in the terminal insertion direction ID at the time of slight sliding, the contact portion 5 contacts the sliding guide protrusion 17 of the spring contact portion 12. . The contact portion 5 is guided by the sliding guide protrusion 17 and moves along one side surface of the sliding guide protrusion 17 (the locus a in FIG. 4C). When the contact portion 5 exceeds the position of the terminal end portion 17b of the sliding guide protrusion 17, the guide restriction of the sliding guide protrusion 17 is released. Thereafter, the contact portion 5 moves (a1 locus in FIG. 4C) while correcting the forcible displacement in the left-right direction by the sliding guide protrusion 17. Further, when the contact portion 5 gets over the inclination of the sliding guide protrusion 17 at a position before the terminal end portion 17b of the sliding guide protrusion 17, the guide restriction of the sliding guide protrusion 17 is released at that time. Thereafter, the contact portion 5 moves (a2 locus in FIG. 4C) while correcting the forcible displacement in the left-right direction by the sliding guide protrusion 17.
　微摺動時におけるタブ端子部３の端子離脱方向ＲＤの移動では、その接点部５がバネ接触部１２の摺動ガイド突部１７に当接する。そして接点部５が摺動ガイド突部１７にガイドされ、摺動ガイド突部１７の他方の側面に沿って移動（図４（ｃ）のｂ軌跡）する。接点部５が摺動ガイド突部１７の始端部１７ａの位置を超えると、摺動ガイド突部１７のガイド規制が解除される。接点部５は、それ以降、摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図４（ｃ）のｂ１軌跡）する。又、接点部５が摺動ガイド突部１７の始端部１７ａの手前位置で摺動ガイド突部１７の傾斜を乗り越えると、その時点で摺動ガイド突部１７のガイド規制が解除される。接点部５は、それ以降、摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図４（ｃ）のｂ２軌跡）する。このように、微摺動時における挿入方向ＩＤの移動と離脱方向ＲＤの移動では、タブ端子部３の接点部５がバネ接触部１２上の異なる軌跡上を移動する。 When the tab terminal portion 3 moves in the terminal detaching direction RD at the time of fine sliding, the contact portion 5 comes into contact with the sliding guide protrusion 17 of the spring contact portion 12. The contact portion 5 is guided by the sliding guide protrusion 17 and moves along the other side surface of the sliding guide protrusion 17 (b locus in FIG. 4C). When the contact portion 5 exceeds the position of the start end portion 17a of the sliding guide protrusion 17, the guide restriction of the sliding guide protrusion 17 is released. Thereafter, the contact portion 5 moves (b1 locus in FIG. 4C) while correcting the forcible displacement in the left-right direction by the sliding guide protrusion 17. When the contact portion 5 gets over the inclination of the sliding guide projection 17 at a position before the start end portion 17a of the sliding guide projection 17, the guide restriction of the sliding guide projection 17 is released at that time. Thereafter, the contact portion 5 moves (b2 locus in FIG. 4C) while correcting the forcible displacement in the left-right direction by the sliding guide protrusion 17. Thus, in the movement in the insertion direction ID and the movement in the separation direction RD at the time of fine sliding, the contact portion 5 of the tab terminal portion 3 moves on different trajectories on the spring contact portion 12.
　以上説明したように、タブ端子部３を有するオス端子２と、筒部１１内に配置されたバネ接触部１２を有するメス端子１０と、タブ端子部３が筒部１１内に挿入され、バネ接触部１２の弾性復帰力を接触荷重としてタブ端子部３とバネ接触部１２間が電気的に接続される端子接続構造１であって、タブ端子部３には、突状の接点部５が設けられ、バネ接触部１２には、タブ端子部３の挿入・離脱方向ｆに対し斜め方向に延びる摺動ガイド突部１７が設けられている。従って、タブ端子部３の接点部５がバネ接触部１２上の異なる軌跡上を移動するため、酸化摩耗粉が１箇所に溜まり難く、摺動回数が増しても酸化摩耗粉が大きく成長することを抑制できる。従って、酸化摩耗粉がバネ接触部１２とタブ端子部３の接点部５の間に介在することに起因する電気抵抗の増大を極力防止できる。 As described above, the male terminal 2 having the tab terminal portion 3, the female terminal 10 having the spring contact portion 12 arranged in the cylindrical portion 11, and the tab terminal portion 3 are inserted into the cylindrical portion 11, and the spring The terminal connection structure 1 is configured such that the tab terminal portion 3 and the spring contact portion 12 are electrically connected using the elastic return force of the contact portion 12 as a contact load. The tab terminal portion 3 has a protruding contact portion 5. The spring contact portion 12 is provided with a sliding guide protrusion 17 extending obliquely with respect to the insertion / removal direction f of the tab terminal portion 3. Therefore, since the contact portion 5 of the tab terminal portion 3 moves on different trajectories on the spring contact portion 12, the oxidized wear powder hardly accumulates in one place, and the oxidized wear powder grows greatly even if the number of sliding times increases. Can be suppressed. Therefore, it is possible to prevent an increase in electrical resistance due to the presence of oxidized wear powder between the spring contact portion 12 and the contact portion 5 of the tab terminal portion 3 as much as possible.
　摺動ガイド突部１７は、細長いストレートな突壁である。従って、摺動ガイド突部１７が接点部５をスムーズにガイドするため、接点部５と摺動ガイド突部１７の端部１７ａ，１７ｂとの接触点における酸化摩耗粉の発生を抑制でき、さらに同時にタブ端子部に過度な左右方向の応力が掛かることによる変形等の異常が発生するのを抑制できる。摺動ガイド突部１７は、ストレート状ではなく、円弧状の曲線でも良く、又、曲線と直線を連続させた形状でも良い。つまり、端子挿入過程と端子離脱過程にあって、タブ端子部３の接点部５をバネ接触部１２の面上の異なる軌跡で摺動するようガイドできる形状であれば良い。 The sliding guide protrusion 17 is an elongated straight protrusion wall. Therefore, since the sliding guide projection 17 smoothly guides the contact portion 5, it is possible to suppress the generation of oxidation wear powder at the contact point between the contact portion 5 and the end portions 17a and 17b of the sliding guide projection 17, At the same time, it is possible to suppress the occurrence of abnormalities such as deformation due to excessive lateral stress applied to the tab terminal portion. The sliding guide protrusion 17 may have a circular arc shape instead of a straight shape, or a shape in which a curved line and a straight line are continuous. In other words, any shape that can guide the contact portion 5 of the tab terminal portion 3 to slide along different trajectories on the surface of the spring contact portion 12 in the terminal insertion process and the terminal removal process may be used.
　摺動ガイド突部１７の始端部１７ａと終端部１７ｂは、曲線状に形成されている。これによって、端部の位置を超えてガイド規制が解除される際の、接点部５と摺動ガイド突部１７の端部１７ａ，１７ｂとの接触点における酸化摩耗粉の発生を抑制できる。 The starting end 17a and the terminal end 17b of the sliding guide protrusion 17 are formed in a curved shape. Accordingly, it is possible to suppress the generation of oxidized wear powder at the contact point between the contact portion 5 and the end portions 17a and 17b of the sliding guide protrusion 17 when the guide restriction is released beyond the position of the end portion.
　実施形態では、タブ端子部３は、フラットな平板状であるが、メス端子１０の筒部１１内に挿入され、バネ接触部１２を撓み変形させて接触荷重を得るものであれば、その形状を問わない。 In the embodiment, the tab terminal portion 3 has a flat plate shape. However, if the tab terminal portion 3 is inserted into the cylindrical portion 11 of the female terminal 10 and the spring contact portion 12 is bent and deformed to obtain a contact load, the shape thereof is used. It doesn't matter.
　実施形態では、筒部１１内にバネ接触部１２が片側に１つ設けられているが、筒部１１内にバネ接触部１２が一対設けられるものであっても良い。この場合には、タブ端子部３の両面に接点部５を設け、且つ、各バネ接触部１２に摺動ガイド突部１７を設けることが好ましい。 In the embodiment, one spring contact portion 12 is provided on one side in the cylinder portion 11, but a pair of spring contact portions 12 may be provided in the cylinder portion 11. In this case, it is preferable to provide the contact portions 5 on both sides of the tab terminal portion 3 and to provide the sliding guide projections 17 on each spring contact portion 12.
　以上、本発明の実施形態について説明したが、これらの実施形態は本発明の理解を容易にするために記載された単なる例示に過ぎず、本発明は当該実施形態に限定されるものではない。本発明の技術的範囲は、上記実施形態で開示した具体的な技術事項に限らず、そこから容易に導きうる様々な変形、変更、代替技術なども含むものである。 As mentioned above, although embodiment of this invention was described, these embodiment is only the mere illustration described in order to make an understanding of this invention easy, and this invention is not limited to the said embodiment. The technical scope of the present invention is not limited to the specific technical matters disclosed in the above embodiment, but includes various modifications, changes, alternative techniques, and the like that can be easily derived therefrom.

　本発明によれば、タブ端子部が微摺動すると、挿入方向の移動と離脱方向の移動ではタブ端子部の接点部がバネ接触部上の異なる軌跡上を移動する。このため、酸化摩耗粉が１箇所に溜まり難く、摺動回数が増しても酸化摩耗粉が大きく成長することを抑制できる。従って、酸化摩耗粉がバネ接触部とタブ端子部の間に介在することに起因する電気抵抗の増大を極力防止できる。 According to the present invention, when the tab terminal portion slides slightly, the contact portion of the tab terminal portion moves on different tracks on the spring contact portion in the movement in the insertion direction and the movement in the separation direction. For this reason, it is difficult for the oxidized wear powder to accumulate in one place, and it is possible to suppress the oxidized wear powder from growing greatly even if the number of sliding times increases. Accordingly, it is possible to prevent an increase in electrical resistance due to the presence of oxidized wear powder between the spring contact portion and the tab terminal portion as much as possible.
