Abstract

<P>PROBLEM TO BE SOLVED: To provide a terminal metal fitting of a connector which eliminates abrasion powder generated when a male tab and a female emboss part slide with each other and eliminates an oxide film to prevent an increase in resistance of a contact surface when connectors are fitted to each other and also are released from fitting. <P>SOLUTION: The female emboss part 13 is formed on a female terminal spring part. The female emboss part 13 is formed in a trapezoidal shape in cross sectional view and is formed in an approximately triangle shape in planar view. An edge 23 is formed between a corner part a on which the male tab abuts first when viewed from an insertion direction A of the male tab, and a surface of the female terminal spring part. When the male tab is inserted in an arrow A direction, the male tab slides with the contact part 13a to generate the abrasion powder 25. However the abrasion powder is separated in an arrow C direction by action of the edge 23. The oxide film of tin or the like formed on the contact surface is also eliminated by sliding. Thereby, an increase in contact resistance of the male tab and female emboss part 13 can be prevented. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、複数の電線の接続及び接続解除を簡便且つ確実に行い得るように構成したコネクタの端子構造に関する。   The present invention relates to a connector terminal structure configured so that a plurality of electric wires can be connected and disconnected easily and reliably.

図１４は、下記特許文献１により開示された端子金具の構成を示すものであり、雌端子金具１００と雄端子金具１５０とから構成されている。両端子金具１００，１５０は図示しないコネクタハウジングに収容されており、コネクタハウジングの嵌合動作により互いに接続される。なお、以下の説明において前後方向については、両端子金具１００，１５０の接続側を前方とする。   FIG. 14 shows the configuration of the terminal fitting disclosed in Patent Document 1 below, which is composed of a female terminal fitting 100 and a male terminal fitting 150. Both terminal fittings 100 and 150 are accommodated in a connector housing (not shown) and are connected to each other by a fitting operation of the connector housing. In the following description, in the front-rear direction, the connection side of both terminal fittings 100, 150 is the front.

雄端子金具１５０は、導電性の金属板を加工して形成されており、前方へ突出する雄タブ１５１を有している。雄タブ１５１はやや幅広でかつ扁平な細長い形状であり、その先端周りに、雌端子金具１００への挿入動作を案内するテーパ面１５２が全周に亘って形成されている。   The male terminal fitting 150 is formed by processing a conductive metal plate, and has a male tab 151 protruding forward. The male tab 151 has a slightly wide and flat elongated shape, and a tapered surface 152 that guides the insertion operation into the female terminal fitting 100 is formed around the entire periphery of the male tab 151.

雌端子金具１００も同じく導電性の金属板を加工して形成されており、その前端部に雄タブ１５１を挿入可能に構成された箱型の本体部１０１が設けられている。
雌端子金具１００の接触片１０３にエンボス加工されたエンボス部１０６が断面視で略台形状であることから、接触片と雄タブとの摺動により発生した摩耗粉は、接触片と雄タブとの摺動面から拡散される。 The female terminal fitting 100 is also formed by processing a conductive metal plate, and a box-shaped main body 101 configured to allow insertion of a male tab 151 is provided at the front end portion thereof.
Since the embossed portion 106 embossed on the contact piece 103 of the female terminal fitting 100 has a substantially trapezoidal shape in a cross-sectional view, the wear powder generated by sliding between the contact piece and the male tab is separated from the contact piece and the male tab. Diffused from the sliding surface.

雄タブ１５１は、本体部１０１内に挿入されて接触片１０３と弾性的に接触される。雄タブ１５１と接触片１０３は、両者が当たり始める始点位置から両者が正規接続される接点位置にかけて、雄タブ１５１の挿入方向に沿って互いに摺動し合う摺動領域Ｙを有する。   The male tab 151 is inserted into the main body 101 and is elastically contacted with the contact piece 103. The male tab 151 and the contact piece 103 have a sliding area Y that slides along the insertion direction of the male tab 151 from the starting point position where they come into contact to the contact position where they are normally connected.

接触片１０３の始点位置には、接点部１０４に供給される潤滑油を保有する凹部１０５（油保有部)が設けられている。雄タブ１５１の挿入時に、接触片１０３と正規接続される接点位置は、図１４の拡大部分に示すように凹部１０５と位置ずれしている。このため、凹部１０５内に溜まった塵埃が雄タブ１５１と接触片１０３との間に挟まるのを防止できる。   At the starting point position of the contact piece 103, a concave portion 105 (oil holding portion) that holds lubricating oil supplied to the contact portion 104 is provided. When the male tab 151 is inserted, the contact position that is normally connected to the contact piece 103 is displaced from the recess 105 as shown in the enlarged portion of FIG. For this reason, it is possible to prevent dust accumulated in the recess 105 from being caught between the male tab 151 and the contact piece 103.

なお、上記凹部１０５は、図１５に示すように接触片１０３上に形成されたエンボス部１０６の頂部に設けられている。従って、上記のように雄タブ１５１が挿入された時、凹部１０５内に導入された潤滑油を雄タブ１５１が受け取り易くなり、潤滑油の雄タブ１５１への付着性及び潤滑性が良好になる。   In addition, the said recessed part 105 is provided in the top part of the embossing part 106 formed on the contact piece 103, as shown in FIG. Therefore, when the male tab 151 is inserted as described above, the male tab 151 can easily receive the lubricating oil introduced into the recess 105, and the adhesion of the lubricating oil to the male tab 151 and the lubricity are improved. .

しかし、上記構成では、雄端子金具１５０の雌端子金具１００への挿入時及び離脱時、更に振動などにより外力が加わった場合、雄タブ１５１及び接触片１０３が互いに移動するようになり、この移動に伴い両者の接点は摺動する。   However, in the above configuration, when an external force is applied due to vibration or the like when the male terminal fitting 150 is inserted into or removed from the female terminal fitting 100, the male tab 151 and the contact piece 103 move relative to each other. As a result, both contacts slide.

上記エンボス部１０６は、上記雄タブ１５１に常に接触しているため、上記摺動時に摩耗粉が発生する。上記エンボス部１０６上の接点部分は円形であるから、摩耗粉を排除する掻き分け効果は少なく、雄タブ１５１とエンボス部１０６との間に摩耗粉が介在してしまう場合がある。   Since the embossed portion 106 is always in contact with the male tab 151, abrasion powder is generated during the sliding. Since the contact portion on the embossed portion 106 is circular, the scraping effect of eliminating the wear powder is small, and the wear powder may be interposed between the male tab 151 and the embossed portion 106.

例えば、メッキ材である錫の摩耗粉が介在した場合、錫の摩耗粉は酸化すると電気的抵抗が高くなる性質を有しているので、雄タブ１５１とエンボス部１０６との接触抵抗が高くなってしまう懸念がある。   For example, when tin wear powder, which is a plating material, is present, since the tin wear powder has a property of increasing electrical resistance when oxidized, contact resistance between the male tab 151 and the embossed portion 106 is increased. There is a concern.

また、経時変化により雄タブ１５１やエンボス部１０６の表面に、抵抗の高い酸化膜が発生することもある。低抵抗で安定した電気的接触を確保するには、酸化膜を除去する必要があるが、円形状のエンボス部１０６及び接点部１０４の構成では酸化膜を除去するワイピング効果が少なかった。   Further, a highly resistant oxide film may be generated on the surface of the male tab 151 or the embossed portion 106 due to a change with time. In order to ensure stable electrical contact with low resistance, it is necessary to remove the oxide film. However, the circular embossed portion 106 and the contact portion 104 have a small wiping effect for removing the oxide film.

本発明の目的は、上記課題を解消することに係り、コネクタ同士を接続する際に雄タブと雌端子バネ部との摺動によって発生する摩耗粉を接触面から拡散させるとともに、摺動により酸化物を除去できるように構成したコネクタの端子金具を提供することにある。   An object of the present invention is to solve the above-mentioned problems. When connecting connectors, wear powder generated by sliding between a male tab and a female terminal spring is diffused from a contact surface and oxidized by sliding. It is an object of the present invention to provide a terminal fitting for a connector configured so that an object can be removed.

以下、本発明に係るコネクタの端子金具の第１実施形態について、図面を参照して詳細に説明する。   Hereinafter, a first embodiment of a terminal fitting of a connector according to the present invention will be described in detail with reference to the drawings.

図１に示すように、雄型コネクタ１と雌型コネクタ３とは、相互に嵌合されるようになっている。図１の左方に示す雄型コネクタ１は、ハウジング５内に導電材料からなる雄タブ７を配設した構成になっている。   As shown in FIG. 1, the male connector 1 and the female connector 3 are fitted to each other. The male connector 1 shown on the left side of FIG. 1 has a structure in which a male tab 7 made of a conductive material is disposed in a housing 5.

これに対し、図１の右方に示す雌型コネクタ３は、ハウジング９内に導電材料からなる雌端子バネ部１１を配設するとともに、その先端部分に雌エンボス部１３を形成した構成になっている。   On the other hand, the female connector 3 shown on the right side of FIG. 1 has a female terminal spring portion 11 made of a conductive material in a housing 9 and a female embossed portion 13 formed at the tip portion thereof. ing.

以下、雌型コネクタ３について説明すると、ハウジング９内には導電材料からなる雌端子１５が抜け出し不可に固定され、雌端子１５の一端に一体に設けられたバレル１７には電線１９の芯線１９ａが加締め止めされている。なお、電線１９の外側は絶縁材からなる被覆材１９ｂにより被覆されている。   Hereinafter, the female connector 3 will be described. A female terminal 15 made of a conductive material is fixed in the housing 9 so as not to be pulled out, and a core wire 19a of an electric wire 19 is attached to a barrel 17 integrally provided at one end of the female terminal 15. It is clamped. The outside of the electric wire 19 is covered with a covering material 19b made of an insulating material.

また、被覆材１９ｂの外側は、弾性を有するパッキン２１により覆われ、電線１９の外側及びハウジング９の内壁からの水分の浸潤を防止できるようになっている。   In addition, the outer side of the covering material 19b is covered with an elastic packing 21 so that moisture can be prevented from infiltrating from the outer side of the electric wire 19 and the inner wall of the housing 9.

そして、図１に示すように雄型コネクタ１と雌型コネクタ３とを嵌合すると、雌型コネクタ３を構成するハウジング９の内筒部分９ａが雄コネクタ１を構成するハウジング５内に入り込み、ハウジング５の外側に設けた係止部５ａとハウジング９に設けた係止部９ｂとが係止し、両者が抜け出し不可に一体化される。   Then, as shown in FIG. 1, when the male connector 1 and the female connector 3 are fitted, the inner cylinder portion 9 a of the housing 9 constituting the female connector 3 enters the housing 5 constituting the male connector 1, The locking portion 5a provided on the outside of the housing 5 and the locking portion 9b provided on the housing 9 are locked, and they are integrated so that they cannot be pulled out.

上記のように雄型コネクタ１と雌型コネクタ３とを嵌合する際、雄タブ７が雌エンボス部１３の表面に当接し、次いで摺動しながら図１に示す位置まで押し込まれる。上記摺動によって摩耗粉が生ずるのであるが、雌端子バネ部１１に下記のような雌エンボス部１３を設けることにより、摩耗粉や酸化被膜の除去を行うことができる。   When the male connector 1 and the female connector 3 are fitted as described above, the male tab 7 comes into contact with the surface of the female embossed portion 13 and is then pushed to the position shown in FIG. 1 while sliding. Although abrasion powder is generated by the sliding, the abrasion powder and oxide film can be removed by providing the female terminal spring portion 11 with the female embossed portion 13 as described below.

雌端子バネ部１１は、図１の拡大部分及び図４に示すように金属板を折り返して全体が弾性を有するように構成されている。そして、雌端子バネ部１１の先端部分であって、上記嵌合時に雄タブ７が当接する位置に雌エンボス部１３が設けられている。   The female terminal spring portion 11 is configured to be elastic as a whole by folding the metal plate as shown in the enlarged portion of FIG. 1 and FIG. And the female embossing part 13 is provided in the front-end | tip part of the female terminal spring part 11, and the position which the male tab 7 contacts at the time of the said fitting.

本実施形態において、雌エンボス部１３は図２（ｂ）に示すように、上部から見た平面視の形状が略二等辺三角形に形成されている。また、図１及び図４に矢印Ａで示した雄タブ７の挿入方向から見た雌エンボス部１３の形状は、図３に示すように略台形状に形成されている。雌エンボス部１３は断面視でも略台形状に形成されている。   In the present embodiment, as shown in FIG. 2B, the female embossed portion 13 is formed in a substantially isosceles triangle shape when viewed from above. Moreover, the shape of the female embossed part 13 seen from the insertion direction of the male tab 7 shown by the arrow A in FIGS. 1 and 4 is formed in a substantially trapezoidal shape as shown in FIG. The female embossed portion 13 is formed in a substantially trapezoidal shape when viewed in cross section.

そして、雌エンボス部１３の上面に形成された略二等辺三角形状の接触部１３ａを構成する頂角、即ち矢印Ａ方向から見て雄タブ７が最初に当接する角部ａから雌端子バネ部１１の表面に向けて傾斜したエッジ２３が形成されている。   And the female terminal spring part from the apex angle which comprises the contact part 13a of the substantially isosceles triangle shape formed in the upper surface of the female embossed part 13, ie, the corner | angular part a which the male tab 7 contacts first seeing from the arrow A direction. The edge 23 inclined toward the surface of 11 is formed.

雌端子バネ部１１及び雌エンボス部１３の構成によれば、雄タブ７を矢印Ａ方向から挿入した場合、雄タブ７の先端がエッジ部２３に懸かる。この状態から、雄タブ７を更に押し込むことにより、雌端子バネ部１１全体が図４に示す矢印Ｂ方向に撓み変形し、雄タブ７が角部ａから挿入量に応じて接触部１３ａの表面に面接触するようになる。   According to the configuration of the female terminal spring portion 11 and the female embossed portion 13, when the male tab 7 is inserted from the direction of arrow A, the tip of the male tab 7 hangs on the edge portion 23. When the male tab 7 is further pushed from this state, the entire female terminal spring portion 11 is bent and deformed in the direction of arrow B shown in FIG. 4, and the male tab 7 is deformed from the corner portion a according to the amount of insertion. Will come into surface contact.

雄タブ７の挿入は、雌エンボス部１３に摺動しつつ行われるので、両者の擦れにより摩耗粉２５が生じる。しかし、本実施形態の構成にあっては、エッジ２３が形成されているので、摩耗粉２５は図４及び図５に矢印Ｃで示すようにエッジ２３の両側に分かれ、雄タブ７と接触部１３ａとの間には介在しなくなる。   Since the insertion of the male tab 7 is performed while sliding on the female embossed portion 13, wear powder 25 is generated by rubbing both. However, in the configuration of the present embodiment, since the edge 23 is formed, the wear powder 25 is divided on both sides of the edge 23 as shown by an arrow C in FIGS. No intervening with 13a.

しかも、本実施形態の構成にあっては、エッジ２３と接触部１３ａの頂角を構成する２辺との間が図２（ｂ）に示すように平面視で９０度以上の角度に設定されている。従って、エッジ２３により分けられた摩耗粉２５は、エッジ２３から延びるテーパ面１３ｂによって次第に拡散されるようになり、雄タブ７と接触部１３ａとの接触面との間に入り込まなくなる。   Moreover, in the configuration of the present embodiment, the angle between the edge 23 and the two sides constituting the apex angle of the contact portion 13a is set to an angle of 90 degrees or more in plan view as shown in FIG. ing. Therefore, the wear powder 25 divided by the edge 23 is gradually diffused by the tapered surface 13b extending from the edge 23, and does not enter between the contact surface of the male tab 7 and the contact portion 13a.

このため、摩耗粉による接触不良を防止できるだけでなく、錫等の酸化膜を摺動により除去するとともに、酸化膜による接触不良をも防止できる。従って、本実施形態を適用したコネクタにあっては、コネクタ同士の嵌合時はもとより、振動等によっても接触不良が生じることがなく、高接触抵抗による電圧低下、発熱等の事故を未然に防止できる。   For this reason, not only contact failure due to wear powder can be prevented, but also an oxide film such as tin can be removed by sliding, and contact failure due to the oxide film can also be prevented. Therefore, in the connector to which this embodiment is applied, contact failure does not occur due to vibration or the like as well as when the connectors are fitted together, and accidents such as voltage drop and heat generation due to high contact resistance are prevented in advance. it can.

次に、本発明の第２実施形態について図面を参照して詳細に説明する。なお、本第２実施形態と上記第１実施形態との相違点は、雌エンボス部について雄タブの挿入方向のみでなく、抜き取り方向についても上記エッジを形成した点にある。従って、上記同様の作用をなす部材については、同一の符号を付して重複説明を省略する。   Next, a second embodiment of the present invention will be described in detail with reference to the drawings. The difference between the second embodiment and the first embodiment is that the edge is formed not only in the insertion direction of the male tab but also in the extraction direction of the female embossed portion. Therefore, members having the same functions as those described above are denoted by the same reference numerals and redundant description is omitted.

図６に示すように、本実施形態においても、雄型コネクタ１と雌型コネクタ３とは、相互に嵌合されるようになっている。   As shown in FIG. 6, also in the present embodiment, the male connector 1 and the female connector 3 are fitted to each other.

以下、図７〜図１２を参照して雌端子バネ部１１について説明すると、雌端子バネ部１１の先端部分であって、上記嵌合時に雄タブ７が当接する位置に図７、図９に示すように雌エンボス部３１が設けられている。   Hereinafter, the female terminal spring portion 11 will be described with reference to FIGS. 7 to 12. FIG. 7 and FIG. 9 are the front end portions of the female terminal spring portion 11 and the positions where the male tab 7 abuts at the time of the fitting. As shown, a female embossed portion 31 is provided.

本実施形態において、雌エンボス部３１は図７（ｂ）に示すように、上部から見た平面視の形状は略菱形状に形成されている。また、図６に矢印Ａで示した雄タブ７の挿入方向から見た形状は図８に示すように台形状に形成されているが、他の側面から見た形状も台形状に形成されている。   In the present embodiment, as shown in FIG. 7B, the female embossed portion 31 has a substantially rhombus shape when viewed from above. Moreover, although the shape seen from the insertion direction of the male tab 7 shown by the arrow A in FIG. 6 is formed in a trapezoid as shown in FIG. 8, the shape seen from the other side is also formed in a trapezoid. Yes.

そして、雌エンボス部３１の上面に形成された略菱角形の接触部３１ａを構成する一の角部、即ち矢印Ａ方向から見て雄タブ７が最初に当接する角部ａから雌端子バネ部１１の表面に向けて傾斜した第１のエッジ３３が形成されている。   Then, the female terminal spring portion is formed from one corner portion constituting the substantially rhomboid contact portion 31a formed on the upper surface of the female embossed portion 31, that is, the corner portion a where the male tab 7 first contacts when viewed from the arrow A direction. 1st edge 33 inclined toward the surface of 11 is formed.

また図６に矢印Ｘで示す雄タブ７の抜き取り方向から見て、最初の角部ｘと雌端子バネ部１１の表面との間に第２のエッジ３５が形成されている。   Further, a second edge 35 is formed between the first corner portion x and the surface of the female terminal spring portion 11 when viewed from the extraction direction of the male tab 7 indicated by an arrow X in FIG.

上記雌端子バネ部１１及び雌エンボス部３１の構成によれば、雄タブ７を矢印Ａ方向から挿入した場合、雄タブ７の先端が第１のエッジ部３３に懸かる。この状態から、雄タブ７を更に押し込むことにより、雌端子バネ部１１全体が図９に示す矢印Ｂ方向に撓み変形し、雄タブ７が角部ａから挿入量に応じて接触部３１ａの表面に面接触するようになる。   According to the configuration of the female terminal spring portion 11 and the female embossed portion 31, when the male tab 7 is inserted from the direction of the arrow A, the tip of the male tab 7 hangs on the first edge portion 33. When the male tab 7 is further pushed in from this state, the entire female terminal spring portion 11 is bent and deformed in the direction of arrow B shown in FIG. 9, and the male tab 7 is surfaced from the corner portion a according to the amount of insertion. Will come into surface contact.

上記雄タブ７の挿入は、雌エンボス部３１に摺動しつつ行われるので、両者の擦れにより摩耗粉２５が生じる。しかし、本実施形態の構成にあっては、第１のエッジ３３が形成されているので、摩耗粉２５は図９及び図１０に矢印Ｃで示すように第１のエッジ３３の両側に分かれ、雄タブ７と接触部３１ａとの間に介在しなくなる。   Since the insertion of the male tab 7 is performed while sliding on the female embossed portion 31, wear powder 25 is generated by rubbing both. However, in the configuration of the present embodiment, since the first edge 33 is formed, the wear powder 25 is divided on both sides of the first edge 33 as shown by arrows C in FIGS. 9 and 10. The male tab 7 is not interposed between the contact portion 31a.

一方、雄タブ７を抜き取る場合は、雌エンボス部３１の接触部３１ａに圧接している状態から抜き取るのであるから、抜き取りに伴って両者が摺動し、摩耗粉２５が生じる。しかし、第２のエッジ３５が形成され、第２のエッジ３５と接触部３１ａの角部ｘを構成する２辺との間が図７（ｂ）に示すように平面視で９０度以上に設定されているので、摩耗粉２５は図１１、図１２に矢印Ｄで示すように分散される。   On the other hand, when the male tab 7 is extracted, since the male tab 7 is extracted from the state where it is in pressure contact with the contact portion 31a of the female embossed portion 31, both slide together with the extraction, and wear powder 25 is generated. However, the second edge 35 is formed, and the interval between the second edge 35 and the two sides constituting the corner portion x of the contact portion 31a is set to 90 degrees or more in plan view as shown in FIG. 7B. Therefore, the wear powder 25 is dispersed as shown by an arrow D in FIGS.

このため、摩耗粉による接触不良を防止できるだけでなく、錫等の酸化膜を摺動により除去するとともに、酸化膜による接触不良をも防止できる。従って、本実施形態を適用したコネクタにあっては、コネクタ同士の嵌合時はもとより、振動等によっても接触不良が生じることがなく、高接触抵抗による電圧低下、発熱等の事故を未然に防止できる。   For this reason, not only contact failure due to wear powder can be prevented, but also an oxide film such as tin can be removed by sliding, and contact failure due to the oxide film can also be prevented. Therefore, in the connector to which this embodiment is applied, contact failure does not occur due to vibration or the like as well as when the connectors are fitted together, and accidents such as voltage drop and heat generation due to high contact resistance are prevented in advance. it can.

次に、上記雌エンボス部の成型方法について説明する。なお、図１３は雌エンボス部１３の成型方法を模式的に示す断面図である。   Next, a method for forming the female embossed portion will be described. FIG. 13 is a cross-sectional view schematically showing a method for forming the female embossed portion 13.

雄金型４１には、雌エンボス部１３を打ち出すための凸部４３が設けられ、雌金型４５には雌エンボス部１３を形成するための凹部４７が設けられている。   The male die 41 is provided with a convex portion 43 for punching out the female embossed portion 13, and the female die 45 is provided with a concave portion 47 for forming the female embossed portion 13.

そして、雄金型４１と雌金型４５との間に板状の雌端子バネ部１１を位置決めし、雄金型４１と雌金型４５とを加圧して雌エンボス部１３を成型する。   Then, the plate-shaped female terminal spring portion 11 is positioned between the male die 41 and the female die 45 and the male die 41 and the female die 45 are pressed to mold the female embossed portion 13.
