Description

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４及び図５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。   As this type of conventional terminal connection structure, there is one shown in FIGS. 4 and 5 (see Patent Document 1 for 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４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５の矢印方向へ弾性変形する。これにより、タブ端子部１０２の筒部１１１内への挿入が許容され、図５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. 4, 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. Thereby, the insertion of the tab terminal portion 102 into the cylindrical portion 111 is allowed, and the state shown in FIG. 5 is obtained. 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.

特開２００７−２８０８２５号公報JP 2007-280825 A

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 detachment process, when the tab terminal portion 102 slides slightly, oxidized wear powder is generated. Here, since the contact part 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, the oxidation wear powder tends to accumulate in one place, and every time the number of sliding increases, the oxidation wear powder. Will grow greatly. 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.

本発明は、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、前記タブ端子部が前記筒部内に挿入され、前記バネ接触部の弾性復帰力を接触荷重として前記タブ端子部と前記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、前記タブ端子部には、突状の接点部が設けられ、前記バネ接触部には、前記タブ端子部の挿入・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、前記タブ端子部の挿入方向の移動では、前記接点部が前記摺動ガイド突部の一方の側面に沿って摺動し、前記タブ端子部の離脱方向の移動では、前記接点部が前記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である。   The present invention relates to a male terminal having a tab terminal portion, a female terminal having a spring contact portion disposed in a cylindrical portion, and the tab terminal portion being inserted into the cylindrical portion so as to contact an elastic return force of the spring contact portion. A terminal connection structure in which the tab terminal portion and the spring contact portion are electrically connected as a load, the tab terminal portion is provided with a projecting contact portion, and the spring contact portion has the A sliding guide protrusion extending obliquely with respect to the insertion / removal direction of the tab terminal portion is provided, and when the tab terminal portion is moved in the insertion direction, the contact portion is along one side surface of the sliding guide protrusion. The terminal connection structure is characterized in that the contact portion slides along the other side surface of the sliding guide protrusion when the tab terminal portion moves in the direction of separation.

前記摺動ガイド突部は、細長いストレートな突壁であるものを含む。   The sliding guide protrusion includes 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 trajectories on the spring contact portion in the movement in the insertion direction and the movement in the separation direction. It is difficult to accumulate in the location, and even if the number of sliding times increases, it can be suppressed that the oxidized wear powder grows greatly. 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.

以下、本発明の一実施形態を図面に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１〜図３は本発明の一実施形態を示す。図１〜図３に示すように、端子接続構造１は、オス端子２とメス端子１０とを備えている。オス端子２は、タブ端子部３と電線加締部４とを有し、所定形状に成形された導電性の板材を折り曲げ加工することにより形成されている。タブ端子部３は、フラットな平板状である。タブ端子部３の下面、つまり、メス端子１０への挿入時にバネ接触部１２に接触する側の面には、図２（ａ）、（ｂ）に詳しく示すように、半球面突状の接点部（インデント部）５が設けられている。接点部５は、タブ端子部３のプレス成形で形成される。   1 to 3 show an embodiment of the present invention. As shown in FIGS. 1 to 3, the terminal connection structure 1 includes a male terminal 2 and a female terminal 10. The male terminal 2 has a tab terminal portion 3 and a wire crimping portion 4, and is formed by bending a conductive plate material formed into a predetermined shape. The tab terminal portion 3 has a flat plate shape. As shown in detail in FIGS. 2A and 2B, the bottom surface of the tab terminal portion 3, that is, the surface that contacts the spring contact portion 12 when inserted into the female terminal 10 A portion (indent portion) 5 is provided. The contact portion 5 is formed by press molding of the tab terminal portion 3.

メス端子１０は、オス端子２のタブ端子部３が内部に挿入される筒部１１と、この筒部１１より延設され、筒部１１内に配置されたバネ接触部１２と、図示しない電線に接続される電線接続部１３と、筒部１１と電線接続部１３の間に配置された首部１４とを有し、所定形状に成形された導電性の板材を折り曲げ加工することにより形成されている。   The female terminal 10 includes a cylindrical portion 11 into which the tab terminal portion 3 of the male terminal 2 is inserted, a spring contact portion 12 that extends from the cylindrical portion 11 and is disposed in the cylindrical portion 11, and an electric wire (not shown). And a neck portion 14 disposed between the tube portion 11 and the wire connection portion 13 and formed by bending a conductive plate material formed into a predetermined shape. Yes.

筒部１１は、天板部１１ａより内側に突出し、タブ端子部３に接触する一対の突部１５と、側板部１１ｂより内側に切り起こして形成され、相手端子挿入方向の直交方向へのバネ接触部１２の過剰変位を規制する過剰変移規制部１６とを備えている。一対の突部１５は、天板部１１ａの幅方向の両側端にタブ端子部３の挿入方向へ沿ってそれぞれ延設され、タブ端子部３の幅方向の両側端と接触する。バネ接触部１２は、底板部１１ｃの前端より延設され、筒部１１内で湾曲されている。   The cylindrical portion 11 protrudes inward from the top plate portion 11a and is formed by cutting and raising a pair of protrusions 15 that come into contact with the tab terminal portion 3 and inward from the side plate portion 11b, and a spring in a direction orthogonal to the mating terminal insertion direction. And an excessive displacement restricting portion 16 that restricts excessive displacement of the contact portion 12. The pair of protrusions 15 are respectively extended along the insertion direction of the tab terminal portion 3 at both end portions in the width direction of the top plate portion 11 a and are in contact with both end portions in the width direction of the tab terminal portion 3. The spring contact portion 12 extends from the front end of the bottom plate portion 11 c and is curved in the cylindrical portion 11.

バネ接触部１２の上面、つまり、タブ端子部３が接触する側の面には、図２（ａ）、（ｃ）に詳しく示すように、上面より突出する摺動ガイド突部１７が設けられている。摺動ガイド突部１７は、細長いストレートな突壁であり、バネ接触部１２のプレス成形で形成される。摺動ガイド突部１７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ている。図２（ｃ）に示すように、摺動ガイド突部１７の始端部１７ａは、タブ端子部３の接点部５の摺動軌跡の左右方向の一方側に変位した位置に位置している。摺動ガイド突部１７の終端部１７ｂは、タブ端子部３の接点部５の摺動軌跡の左右方向の他方側に変位した位置に位置している。   As shown in detail in FIGS. 2 (a) and 2 (c), a sliding guide protrusion 17 protruding from the upper surface is provided on the upper surface of the spring contact portion 12, that is, the surface on the side where the tab terminal portion 3 contacts. ing. The sliding guide protrusion 17 is an elongated straight protrusion wall and is formed by press forming the spring contact portion 12. The sliding guide protrusion 17 extends obliquely with respect to the insertion / removal direction f of the tab terminal portion 3. As shown in FIG. 2C, the start end portion 17 a of the sliding guide protrusion 17 is located at a position displaced to one side in the left-right direction of the sliding locus of the contact portion 5 of the tab terminal portion 3. The terminal end portion 17 b of the sliding guide protrusion 17 is located at a position displaced to the other side in the left-right direction of the sliding locus of the contact portion 5 of the tab terminal portion 3.

上記構成において、図２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３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３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. 2, 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. As a result, the tab terminal portion 3 is allowed to be inserted into the cylinder 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３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が離脱方向に移動して筒部１１より引き抜かれる。   In the terminal connection state of FIG. 3, 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 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２（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に当接し、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の一方の側面に沿って移動（図２（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、それ以降は摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図２（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、それ以降は摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図２（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. 2C, in the movement of the tab terminal portion 3 in the terminal insertion direction at the time of slight sliding, the contact portion 5 abuts on 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. 2C). 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, and thereafter, the sliding displacement of the sliding guide protrusion 17 is forced in the left-right direction. It moves while correcting (al trajectory in FIG. 2C). Further, when the contact portion 5 gets over the inclination of the sliding guide projection 17 at a position before the end portion 17b of the sliding guide projection 17, the guide restriction of the sliding guide projection 17 is released at that time, and thereafter Moves while correcting the forced displacement in the left-right direction by the sliding guide projection 17 (a2 locus in FIG. 2C).

微摺動時におけるタブ端子部３の端子離脱方向の移動では、その接点部５がバネ接触部１２の摺動ガイド突部１７に当接し、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２（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、それ以降は摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図２（ｃ）のｂ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、それ以降は摺動ガイド突部１７による左右方向への強制変位を修正しつつ移動（図２（ｃ）のｂ２軌跡）する。このように、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、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。   In the movement of the tab terminal portion 3 in the terminal detachment direction during slight sliding, the contact portion 5 comes into contact with the sliding guide projection 17 of the spring contact portion 12, and the contact portion 5 is guided by the sliding guide projection 17. Then, it moves along the other side surface of the sliding guide protrusion 17 (b locus in FIG. 2C). When the contact portion 5 exceeds the position of the start end portion 17a of the sliding guide projection 17, the guide regulation of the sliding guide projection 17 is released, and thereafter, the forced displacement in the left-right direction by the sliding guide projection 17 is released. It moves while correcting (b trajectory in FIG. 2C). Further, 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, and thereafter Moves while correcting the forced displacement in the left-right direction by the sliding guide protrusion 17 (b2 locus in FIG. 2C). As described above, the contact portion 5 of the tab terminal portion 3 moves on different trajectories on the spring contact portion 12 in the movement in the insertion direction and the movement in the separation direction during the fine sliding.

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。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, the sliding guide protrusion 17 smoothly guides the contact portion 5. 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.

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 cylindrical portion 11, but a pair of spring contact portions 12 may be provided in the cylindrical 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.
