Description

本発明は、アース端子に関する。   The present invention relates to a ground terminal.

自動車に配索されるワイヤーハーネス等においては、アース用の電線の端末に圧着されたアース端子をボディの所定位置に取り付けることにより、アースをとるようになっているのが一般的である。自動車のボディには、ボディの所定位置に予め溶接固定されたナットとともに、腐食防止のための塗装が施されているため、塗装により形成された塗装膜を介してアース端子をボディにボルト締めすると、塗装膜にへたりが生じた際に、アース端子にがたつきが生じることがある。   Generally, in a wire harness or the like routed in an automobile, grounding is performed by attaching a ground terminal crimped to the end of a grounding electric wire to a predetermined position of the body. The body of the car is painted to prevent corrosion along with a nut that is welded and fixed in place on the body in advance, so if you bolt the grounding terminal to the body through a paint film formed by painting When the coating film sags, the ground terminal may be rattled.

この問題を解決する方法として、アース端子とボディの金属面との間の塗装膜を剥ぎ取って、アース端子とボディの金属面との金属同士を固定する方法がある(例えば特許文献1を参照)。   As a method for solving this problem, there is a method in which the paint film between the ground terminal and the metal surface of the body is peeled off to fix the metal between the ground terminal and the metal surface of the body (for example, see Patent Document 1). ).

特許文献1には、アース端子の取付孔の孔縁に沿って設けた複数の削剥部がナットの上端面の塗装膜を削るように剥がすことで、ナットの上端面を露出させる構成が記載されている。これにより、アース端子とナットとが導通可能に接触させることができるようになっている。   Patent Document 1 describes a configuration in which the upper end surface of the nut is exposed by peeling off a plurality of scraping portions provided along the edge of the mounting hole of the ground terminal so as to scrape the coating film on the upper end surface of the nut. ing. As a result, the ground terminal and the nut can be brought into contact with each other so as to be conductive.

特開平10−125374号公報JP 10-125374 A

上記特許文献1に記載の発明においては、削剥部が、ボルトの取付孔の孔縁に沿って曲げ加工により設けられているので、塗装膜の状態によっては、削剥部が塗装膜を剥がして金属面が露出する前に、ボルトの締めつけに伴い削剥部が孔の内部にのびて平坦な姿勢になってしまうと、塗装膜が意図したとおりに剥ぎ取られない可能性があった。そのためアース端子をナットの金属面に確実に接続できなくなることが懸念された。   In the invention described in Patent Document 1, since the scraped portion is provided by bending along the hole edge of the bolt mounting hole, the scraped portion peels off the coated film depending on the state of the coated film. Before the surface is exposed, if the scraped portion extends into the hole and becomes flat as the bolt is tightened, the coating film may not be peeled off as intended. Therefore, there is a concern that the ground terminal cannot be reliably connected to the metal surface of the nut.

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、アース端子をボディに対し確実に接続することを目的とする。   The present invention has been completed based on the above circumstances, and an object thereof is to reliably connect a ground terminal to a body.

本発明は、導電性の金属からなる筐体の接地面に非導電膜が被着されてなるボディに対してボルトで取り付けられるアース端子であって、前記ボルトを挿通可能な取付孔を有する端子本体部を備え、前記端子本体部における、前記ボルトとの締結部のうち、前記ボルトの締め付けによる軸方向の力を受ける領域に、前記接地面側に突出形成される突出部が設けられ、前記突出部は前記ボルトの締め付けに伴い前記非導電膜を突き抜けて前記接地面に食い込む食い込み部を有するアース端子である。   The present invention is a ground terminal that is attached to a body in which a non-conductive film is attached to a grounding surface of a casing made of a conductive metal, and has a mounting hole through which the bolt can be inserted. A projecting portion that is formed to project toward the grounding surface side in a region that receives an axial force due to tightening of the bolt, of the fastening portion with the bolt in the terminal body portion, The projecting portion is a ground terminal having a biting portion that penetrates the non-conductive film and bites into the grounding surface as the bolt is tightened.

本発明においては、ボルトとの締結部のうち、ボルトの締めつけによる軸方向の力を受ける領域に突出部が設けられているので、ボルトが挿通され取り付けられる取付孔の孔縁に沿って設けられている場合のように、平坦な姿勢になりにくく、ボルトの締め付けによる軸方向の力を直接受ける。その結果、本発明によれば、ボルトの締め付けによる軸方向の力を直接受けて、突出部の食い込み部が接地面の非導電膜を突き抜けて接地面に食い込むので、アース端子をボディに対し確実に接続することができる。   In the present invention, since the protruding portion is provided in the region that receives the axial force generated by tightening the bolt among the fastening portions with the bolt, the protruding portion is provided along the hole edge of the mounting hole through which the bolt is inserted and attached. As in the case of the case, it is difficult to become a flat posture, and the axial force due to the bolt tightening is directly received. As a result, according to the present invention, the axial force due to bolt tightening is directly received, and the biting portion of the protruding portion penetrates the non-conductive film on the ground surface and bites into the ground surface, so that the ground terminal is securely attached to the body. Can be connected to.

本発明は以下の構成であってもよい。
複数の前記突出部が等間隔で設けられていてもよい。このような構成とするとアース端子の筐体への着座姿勢が安定するので、アース端子と接地面との固定及び導通が安定する。
The present invention may have the following configuration.
A plurality of the protrusions may be provided at equal intervals. With such a configuration, since the seating posture of the ground terminal on the housing is stabilized, fixing and conduction between the ground terminal and the ground plane are stabilized.

前記食い込み部の形状が円形状であってもよい。このような構成とするとアース端子の食い込み部と接地面との接触部分が増えるので、電気的な接続が安定する。   The biting portion may have a circular shape. With such a configuration, the contact portion between the biting portion of the ground terminal and the ground plane increases, so that the electrical connection is stabilized.

前記アース端子と前記ボルトとの間にワッシャーを備え、前記突出部が前記締結部の前記ワッシャーの投影範囲に設けられていてもよい。
このような構成とすると、ボルトの回転によるアース端子の傷つきを防止することができる。加えて、上記のような構成とすると、ワッシャーがボルトの締めつけによる軸方向の力を受けて、ワッシャー面がアース端子の締結部を押すので、締結作業の際にアース端子が傾きにくく締結作業を効率的に行え、アース端子と接地面との固定および導通も安定する。
A washer may be provided between the ground terminal and the bolt, and the protruding portion may be provided in a projection range of the washer of the fastening portion.
With such a configuration, it is possible to prevent the ground terminal from being damaged by the rotation of the bolt. In addition, with the configuration as described above, the washer receives the axial force caused by tightening the bolt, and the washer surface pushes the fastening portion of the grounding terminal. It can be performed efficiently, and the fixing and conduction between the ground terminal and the ground plane are also stable.

本発明によれば、アース端子をボディに対し確実に接続することができる。   According to the present invention, the ground terminal can be reliably connected to the body.

<実施形態1>
本発明の実施形態1を図1ないし図8によって説明する。
本実施形態におけるアース端子10は、導電性の金属からなる筐体31の接地面32に塗装膜33(非導電膜の一例)が被着されてなるボディ30に対して、ボルト25によって取り付けられる。以下、各構成部材において、上下方向については、図2、図7および図8を基準とする。また、アース端子10の前後方向については、図2の左側を前方とし、図2の右側(電線20側)を後方とする。
<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS.
The ground terminal 10 in the present embodiment is attached by a bolt 25 to a body 30 in which a coating film 33 (an example of a non-conductive film) is attached to a ground surface 32 of a casing 31 made of a conductive metal. . Hereinafter, in each constituent member, the vertical direction is based on FIGS. 2, 7, and 8. Moreover, about the front-back direction of the ground terminal 10, let the left side of FIG. 2 be the front, and let the right side (electric wire 20 side) of FIG. 2 be the back.

ボディ30は、導電性の良い金属製の筐体31を有しており、図6〜図8に示すように、筐体31の表面がアース接続用の接地面32とされている。この接地面32は、腐食防止のための塗装処理により形成された塗装膜33によって覆われている。また、ボディ30の筐体31には、ボルト25と螺合可能な雌ネジ孔34が接地面32に開口して形成されている。   The body 30 has a metal casing 31 with good conductivity. As shown in FIGS. 6 to 8, the surface of the casing 31 is a grounding surface 32 for ground connection. The ground plane 32 is covered with a coating film 33 formed by a coating process for preventing corrosion. Further, a female screw hole 34 that can be screwed into the bolt 25 is formed in the housing 31 of the body 30 so as to open to the ground surface 32.

ボルト25は六角形の頭部27を有しており、その頭部27よりも拡径した円形のワッシャー28が一体となった構成とされる。また、ボルト25は、雌ネジ孔34と螺合可能な雄ネジが形成された軸部26を有している。   The bolt 25 has a hexagonal head 27, and a circular washer 28 whose diameter is larger than that of the head 27 is integrated. The bolt 25 has a shaft portion 26 in which a male screw that can be screwed into the female screw hole 34 is formed.

アース端子10には、図1および図2に示すように、ワイヤーハーネスの電線20が圧着されるオープンバレル形式のワイヤバレル18とインシュレーションバレル19とが設けられている。ワイヤバレル18は、電線20の端末において絶縁被覆22の剥離により露出する芯線21にかしめられており、ワイヤバレル18の後方に形成されたインシュレーションバレル19は、電線20の絶縁被覆22で覆われた被覆部23にかしめられている。   As shown in FIGS. 1 and 2, the ground terminal 10 is provided with an open barrel type wire barrel 18 and an insulation barrel 19 to which the wire 20 of the wire harness is crimped. The wire barrel 18 is caulked to the core wire 21 exposed by peeling off the insulating coating 22 at the end of the electric wire 20, and the insulation barrel 19 formed behind the wire barrel 18 is covered with the insulating coating 22 of the electric wire 20. The cover portion 23 is caulked.

さらに、アース端子10には、ワイヤバレル18の前方に連なり、ボディ30にボルト25によって締結される端子本体部11が一体に設けられている。端子本体部11は、全体として角部が丸くされた略正方形の板状をなし、その中心には、円形の取付孔13が形成されている。この取付孔13は、ボルト25の軸部26が挿通可能とされており、取付孔13の内径寸法が、軸部26の外径寸法よりもわずかに大きい寸法に設定されている。このことにより、取付孔13の孔縁が軸部26のネジ山と当接することで、ボルト25と端子本体部11との中心位置がほぼ同じになるように保たれるようになっている。   Further, the ground terminal 10 is integrally provided with a terminal main body 11 that is connected to the front of the wire barrel 18 and is fastened to the body 30 by a bolt 25. The terminal body 11 has a substantially square plate shape with rounded corners as a whole, and a circular mounting hole 13 is formed at the center thereof. The shaft hole 26 of the bolt 25 can be inserted into the mounting hole 13, and the inner diameter of the mounting hole 13 is set to be slightly larger than the outer diameter of the shaft 26. As a result, the hole edge of the mounting hole 13 abuts against the thread of the shaft portion 26 so that the center positions of the bolt 25 and the terminal main body portion 11 are kept substantially the same.

端子本体部11の取付孔13の周囲の領域は、ボルト25の締め付けにより発生する力を受ける締結部12である。本実施形態においては、アース端子10の端子本体部11の締結部12とボルト25との間にワッシャー28が配されているので、ボルト25の締め付けによる軸方向(図7における矢線Xの方向)の力は、締結部12のうち、ワッシャー28の上面と当接する領域に直接かかって、端子本体部11が下方に押されるようになっている。   A region around the attachment hole 13 of the terminal body 11 is a fastening portion 12 that receives a force generated by tightening the bolt 25. In the present embodiment, since the washer 28 is disposed between the fastening portion 12 of the terminal body 11 of the ground terminal 10 and the bolt 25, the axial direction (the direction of the arrow X in FIG. ) Is applied directly to the region of the fastening portion 12 that contacts the upper surface of the washer 28, and the terminal body 11 is pushed downward.

つまり、端子本体部11の締結部12のうち、ワッシャー28と当接する領域がボルト25の締め付けによる軸方向の力を受ける領域14に相当し、当該領域14は、図1に示すように、ワッシャー28の投影範囲15(図1の二点鎖線で囲まれたドーナツ状の領域)内である。   That is, in the fastening portion 12 of the terminal body 11, a region that contacts the washer 28 corresponds to a region 14 that receives an axial force due to tightening of the bolt 25, and the region 14 is, as shown in FIG. 28 projection ranges 15 (a donut-shaped region surrounded by a two-dot chain line in FIG. 1).

本実施形態においては、端子本体部11における端子本体部11の締結部12のうち、ボルト25の締め付けによる軸方向の力を受ける領域14には、接地面32側(下方)に突出形成される突出部16が4つ(複数)設けられている。   In the present embodiment, in the fastening part 12 of the terminal body part 11 in the terminal body part 11, the region 14 that receives the axial force due to the tightening of the bolt 25 is formed to project toward the ground plane 32 side (downward). Four (plural) protrusions 16 are provided.

4つの突出部16(複数の突出部16)は、等間隔で設けられている。突出部16は、図3および図4に示すように、中心に貫通孔17Bを有するとともに上面側が凹んで下方へ突出する形状である。突出部16は、例えば、バーリング加工によって形成することができる。   The four protrusions 16 (the plurality of protrusions 16) are provided at equal intervals. As shown in FIGS. 3 and 4, the protruding portion 16 has a through hole 17 </ b> B at the center and has a shape in which the upper surface side is recessed and protrudes downward. The protrusion 16 can be formed by, for example, burring.

この突出部16は、ボルト25の締め付けに伴い塗装膜33を突き抜けて金属製の接地面32に食い込む食い込み部17Aを有する。食い込み部17Aは図5に示すように、下面側(突出方向側)から見ると(底面視)、円形状をなしている。また、食い込み部17Aは、図7および図8に示すように、斜め下方に突出するとともにその先端が尖った形状をなしており、食い込み部17Aの先端が塗装膜33を突き抜けて接地面32に食い込むことにより、アース端子10をボディ30に対し接続するようになっている。   The projecting portion 16 has a biting portion 17 </ b> A that penetrates the coating film 33 and bites into the metal ground surface 32 as the bolt 25 is tightened. As shown in FIG. 5, the biting portion 17 </ b> A has a circular shape when viewed from the lower surface side (projection direction side) (bottom view). As shown in FIGS. 7 and 8, the biting portion 17 </ b> A protrudes obliquely downward and has a sharp tip, and the tip of the biting portion 17 </ b> A penetrates the coating film 33 to the ground surface 32. The ground terminal 10 is connected to the body 30 by biting in.

次に、本実施形態のアース端子10の製造方法について説明する。
アース端子10は、導電性の金属板材にうちぬき加工や曲げ加工等を施すことにより作製することができる。このときに端子本体部11のうち、ボルト25の締付による軸方向の力を受ける領域14(ワッシャー28と当接する領域)にバーリング加工等により突出部16を形成しておく。
Next, the manufacturing method of the ground terminal 10 of this embodiment is demonstrated.
The ground terminal 10 can be produced by subjecting a conductive metal plate material to punching or bending. At this time, the protruding portion 16 is formed by burring or the like in the region 14 (region in contact with the washer 28) that receives the axial force generated by tightening the bolt 25 in the terminal body 11.

次に、端末の絶縁被覆22を剥離除去することにより芯線21を露出させておいた電線20をアース端子10に接続する。具体的にはアース端子10のワイヤバレル18に電線20の端末において露出した芯線21を配し、インシュレーションバレル19に電線20の端末において絶縁被覆22により覆われた被覆部23を配して各バレル部を電線20の端末に圧着させて接続する。これにより図1および図2に示すアース端子10が得られる。   Next, the electric wire 20 in which the core wire 21 is exposed by peeling off and removing the insulating coating 22 of the terminal is connected to the ground terminal 10. Specifically, the core wire 21 exposed at the end of the electric wire 20 is arranged on the wire barrel 18 of the ground terminal 10, and the covering portion 23 covered with the insulating coating 22 is arranged on the insulation barrel 19 at the end of the electric wire 20. The barrel part is connected to the end of the electric wire 20 by crimping. As a result, the ground terminal 10 shown in FIGS. 1 and 2 is obtained.

次にアース端子10の取付方法について説明する。
図7に示すように、ボディ30の筐体31に設けた雌ネジ孔34の中心軸(Y−Y線)とアース端子10の取付孔13の中心軸(Z−Z線)が一致するように配した後、アース端子10の取付孔13と筐体31の雌ネジ孔34とにボルト25の軸部26を挿入し、ボルト25の軸部26を雌ネジ孔34に螺合させる。
Next, a method for attaching the ground terminal 10 will be described.
As shown in FIG. 7, the central axis (YY line) of the female screw hole 34 provided in the housing 31 of the body 30 and the central axis (ZZ line) of the mounting hole 13 of the ground terminal 10 coincide with each other. After that, the shaft portion 26 of the bolt 25 is inserted into the mounting hole 13 of the ground terminal 10 and the female screw hole 34 of the housing 31, and the shaft portion 26 of the bolt 25 is screwed into the female screw hole 34.

ボルト25を締め付けることにより、ボルト25の頭部27とワッシャー28の上面が当接し、かつ、ワッシャー28の下面がアース端子10の端子本体部11の上面に当接すると、アース端子10の端子本体部11は、ボルト25の締め付けによる軸方向の力を受けて下方に押される。本実施形態では4つの突出部16が等間隔で設けられているので、アース端子10が筐体31に対して安定した着座姿勢をとりつつ下方に押される。   When the bolt 25 is tightened, the head portion 27 of the bolt 25 and the upper surface of the washer 28 come into contact with each other, and the lower surface of the washer 28 comes into contact with the upper surface of the terminal main body portion 11 of the ground terminal 10. The part 11 receives an axial force due to the tightening of the bolt 25 and is pushed downward. In the present embodiment, since the four projecting portions 16 are provided at equal intervals, the ground terminal 10 is pushed downward while taking a stable seating posture with respect to the housing 31.

アース端子10の締結部12のうち、ボルト25の締め付けによる軸方向の力を受ける領域14が下方に押されると、突出部16に設けた食い込み部17Aの先端が塗装膜33に食い込み、食い込み部17Aが塗装膜33を貫通して筐体31の接地面32(金属面)に接触する(図8を参照)。これによりアース端子10の取り付けは完了する。   When the region 14 that receives the axial force due to the tightening of the bolt 25 is pushed downward in the fastening portion 12 of the ground terminal 10, the tip of the biting portion 17A provided in the protruding portion 16 bites into the coating film 33, and the biting portion 17A penetrates the coating film 33 and contacts the grounding surface 32 (metal surface) of the casing 31 (see FIG. 8). Thereby, the attachment of the ground terminal 10 is completed.

次に本実施形態の作用および効果を説明する。
本実施形態においては、ボルト25との締結部12のうち、ボルト25の締めつけによる軸方向の力を受ける領域14に突出部16が設けられているので、ボルトが挿通され取り付けられる取付孔の孔縁に沿って突出部が設けられている場合のように、平坦な姿勢になりにくく、ボルト25の締め付けによる軸方向の力を直接受ける。その結果、本実施形態によれば、ボルト25の締め付けによる軸方向の力を直接受けて、突出部16の食い込み部17Aが接地面32の塗装膜33を突き抜けて接地面32に食い込むので、アース端子10をボディ30に対し確実に接続することができる。
Next, the operation and effect of this embodiment will be described.
In the present embodiment, the protrusion 16 is provided in the region 14 that receives the axial force generated by tightening the bolt 25 in the fastening portion 12 with the bolt 25, so that the hole of the mounting hole into which the bolt is inserted and attached. As in the case where the protruding portion is provided along the edge, it is difficult to become a flat posture, and an axial force due to tightening of the bolt 25 is directly received. As a result, according to the present embodiment, the axial force generated by tightening the bolt 25 is directly received, and the biting portion 17A of the protruding portion 16 penetrates the coating film 33 of the grounding surface 32 and bites into the grounding surface 32. The terminal 10 can be reliably connected to the body 30.

また、本実施形態によれば、4つ(複数)の突出部16が等間隔で設けられているから、アース端子10の筐体31への着座姿勢が安定するので、アース端子10と接地面32との固定及び導通が安定する。   In addition, according to the present embodiment, since the four (plural) protrusions 16 are provided at equal intervals, the seating posture of the ground terminal 10 on the housing 31 is stable. Fixing and conduction with 32 is stabilized.

また、本実施形態によれば、食い込み部17Aの形状が円形状であるから、食い込み部17Aが点状の場合等よりも、アース端子10の食い込み部17Aと接地面32との接触部分が増えるので、電気的な接続が安定する。   Further, according to the present embodiment, since the shape of the biting portion 17A is a circular shape, the contact portion between the biting portion 17A of the ground terminal 10 and the ground plane 32 is increased as compared with the case where the biting portion 17A has a dot shape or the like. So the electrical connection is stable.

また、本実施形態によれば、アース端子10とボルト25との間にワッシャー28を備え、突出部16が締結部12のワッシャー28の投影範囲15に設けられているから、ボルト25の回転によるアース端子10の傷つきを防止することができる。そのうえ、ワッシャー28がボルト25の締めつけによる軸方向の力を受けて、ワッシャー28面がアース端子10の締結部12を押すので、締結作業の際にアース端子10が傾きにくく締結作業を効率的に行え、アース端子10と接地面32との固定および導通も安定する。   Further, according to the present embodiment, the washer 28 is provided between the ground terminal 10 and the bolt 25, and the projecting portion 16 is provided in the projection range 15 of the washer 28 of the fastening portion 12. The ground terminal 10 can be prevented from being damaged. In addition, the washer 28 receives an axial force due to the tightening of the bolt 25, and the surface of the washer 28 presses the fastening portion 12 of the ground terminal 10. Therefore, the ground terminal 10 is hard to tilt during the fastening work, and the fastening work is efficiently performed. This is possible, and the fixing and conduction between the ground terminal 10 and the ground plane 32 are also stabilized.
