特開２０１０−３３７８３号公報JP, 2010-33783, A

しかしながら、上記のような構成では、バッテリ端子の展開形状が大きくなるため、歩留まりが悪いという問題がある。すなわち上記のような構成のバッテリ端子の展開形状は、図１１に示すように、ポスト接続部及び一対の突出部を構成する部分１００と、電線接続部を構成する部分１０１とが、概ねＴ字形状をなすように繋がった形状になる。このような形状の金属板材が、細長いキャリアに沿って複数並んだ状態で打ち抜かれると、電線接続部を構成する部分１０１の両側が廃棄部分１０２になる。この廃棄部分は、バッテリ端子を構成する部分に対して比較的大きい面積を有するため、歩留まりがよくないという問題がある。   However, in the configuration as described above, there is a problem that the yield is bad because the expanded shape of the battery terminal becomes large. That is, as shown in FIG. 11, in the expanded shape of the battery terminal having the above-described configuration, the portion 100 forming the post connection portion and the pair of protrusions and the portion 101 forming the wire connection portion are generally T-shaped. It becomes a shape connected to form a shape. When a plurality of metal plate members having such a shape are punched out in a plurality along the elongated carrier, both sides of the portion 101 constituting the wire connection portion become the waste portion 102. Since this waste portion has a relatively large area with respect to the portion constituting the battery terminal, there is a problem that the yield is not good.

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、歩留まりをよくすることが可能なバッテリ端子を提供することを目的とする。   The present invention is completed based on the above-mentioned circumstances, and it aims at providing a battery terminal which can improve a yield.

本発明のバッテリ端子は、バッテリポストの外周側を包囲するとともに周方向の一部が開放された形状をなすポスト接続部、及び前記ポスト接続部の周方向における両端から径方向の外側に突出し、締結部材により互いの間隔が狭められることで前記ポスト接続部を縮径させる一対の突出部を有する端子本体部と、前記端子本体部とは別体であり、前記締結部材により前記突出部に締結されることで前記端子本体部と電気的に接続される端子金具と、を備えているものである。   The battery terminal according to the present invention projects radially outward from both ends of the post connection portion which surrounds the outer peripheral side of the battery post and has a shape in which a part in the circumferential direction is opened, and the post connection portion. The terminal main body portion having a pair of projecting portions for reducing the diameter of the post connection portion by the mutual narrowing by the fastening members is separate from the terminal main body portion, and is fastened to the projecting portions by the fastening members. And a terminal fitting electrically connected to the terminal main body by being carried out.

本発明によれば、端子本体部の展開形状が小さくなるため、端子圧着部を一体に有しないから、従来に比して廃棄部分を小さくすることができ、もって歩留まりをよくすることができる。   According to the present invention, since the expanded shape of the terminal main body portion is reduced, the terminal crimping portion is not integrally provided. Therefore, the waste portion can be reduced as compared with the conventional case, and the yield can be improved.

以下、本発明を具体化した一実施例について、図１〜図１０を参照しつつ詳細に説明する。
本実施例におけるバッテリ端子Ｔは、図１または図２に示すように、バッテリ本体Ｂの上面に突出するバッテリポストＰに対し、電線Ｗを電気的に接続するためのものである。バッテリ端子Ｔは、バッテリポストＰに固定される端子本体部１０と、電線Ｗの端末部に接続される端子金具２０と、を別体に備えている。端子本体部１０及び端子金具２０は、それぞれ導電性に優れた金属板材をプレス加工する等によって製造されている。 <Example>
Hereinafter, an embodiment embodying the present invention will be described in detail with reference to FIGS. 1 to 10.
The battery terminal T in the present embodiment is for electrically connecting the electric wire W to the battery post P protruding on the upper surface of the battery main body B, as shown in FIG. 1 or 2. The battery terminal T is separately provided with a terminal body 10 fixed to the battery post P and a terminal fitting 20 connected to the end of the electric wire W. Each of the terminal body 10 and the terminal fitting 20 is manufactured by pressing a metal plate material excellent in conductivity.

端子本体部１０は、バッテリポストＰに嵌合してバッテリポストＰに電気的に接続されるポスト接続部１１と、ポスト接続部１１の径寸法を調整するために設けられた一対の突出部１２とを備えている。   The terminal body portion 10 has a post connection portion 11 fitted to the battery post P and electrically connected to the battery post P, and a pair of projecting portions 12 provided for adjusting the diameter dimension of the post connection portion 11.

ポスト接続部１１は、図７に示すように、バッテリポストＰの外周側を包囲するとともに周方向の一部が開放された形状をなしている。ポスト接続部１１は、軸線を上下方向に向けた円弧形状をなしている。ポスト接続部１１の径寸法は、上端縁において最小であり、下端において最大とされ、全体としてバッテリポストＰと同様の円錐台形をなしている。   As shown in FIG. 7, the post connection portion 11 surrounds the outer periphery of the battery post P and has a shape in which a part in the circumferential direction is opened. The post connection portion 11 has an arc shape in which the axis is directed in the vertical direction. The diameter dimension of the post connection portion 11 is smallest at the upper end edge and maximized at the lower end, and has a generally frusto-conical shape similar to the battery post P.

ポスト接続部１１は、バッテリポストＰに取り付けられる前は、径寸法がバッテリポストＰより一回り大きい拡径状態となっている。拡径状態では、ポスト接続部１１の径寸法は、バッテリポストＰに対して上方から円滑に嵌合できる程度のクリアランスを有している。ポスト接続部１１は、一対の突出部１２が接近することに伴って縮径するように変形する。   Before the post connection portion 11 is attached to the battery post P, the diameter of the post connection portion 11 is a diameter expansion state that is slightly larger than that of the battery post P. In the enlarged diameter state, the diameter of the post connection portion 11 has a clearance that allows the battery post P to be smoothly fitted from above. The post connection portion 11 deforms so as to reduce in diameter as the pair of protruding portions 12 approaches.

ポスト接続部１１の下端には、バッテリ本体Ｂの上面に沿って配される板状部１３が設けられている。板状部１３は、ポスト接続部１１の下端から径方向の外側に突出している。板状部１３は、ポスト接続部１１の外径と同等の幅寸法を有している。板状部１３は、図８に示すように、ポスト接続部１１の中心軸を間にして一対の突出部１２とは反対側に設けられている。   At the lower end of the post connection portion 11, a plate-like portion 13 disposed along the upper surface of the battery main body B is provided. The plate-like portion 13 protrudes outward in the radial direction from the lower end of the post connection portion 11. The plate-like portion 13 has a width that is equal to the outer diameter of the post connection portion 11. As shown in FIG. 8, the plate-like portion 13 is provided on the side opposite to the pair of projecting portions 12 with the central axis of the post connecting portion 11 interposed therebetween.

板状部１３には、図示しないバッテリカバーに係止するカバー係止部１４が設けられている。カバー係止部１４は、ポスト接続部１１を間にした両側に一対が設けられている。カバー係止部１４は、板状部１３の外周縁から上方に立ち上がるとともに、上端部が外向きに略直角に屈曲された形状をなしている。   The plate-like portion 13 is provided with a cover engaging portion 14 which is engaged with a battery cover (not shown). A pair of cover locking portions 14 is provided on both sides of the post connection portion 11. The cover locking portion 14 rises upward from the outer peripheral edge of the plate-like portion 13 and has a shape in which an upper end portion is bent outward substantially at a right angle.

一対の突出部１２は、図７及び図８に示すように、ポスト接続部１１の周方向における両端から径方向の外側に突出した平板状をなしている。一対の突出部１２は、ポスト接続部１１と一体に形成されている。一対の突出部１２は、概ね同じ大きさの方形状をなしている。一対の突出部１２は、板面の間に一定の間隔が空いた略平行をなしている。
一対の突出部１２には、締結部材３０が貫通される貫通穴１５が形成されている。貫通穴１５は、円形状をなしている。 As shown in FIG. 7 and FIG. 8, the pair of projecting portions 12 has a flat plate shape projecting outward in the radial direction from both ends in the circumferential direction of the post connection portion 11. The pair of protrusions 12 are integrally formed with the post connection portion 11. The pair of protrusions 12 have a square shape of substantially the same size. The pair of protrusions 12 are substantially parallel with a constant gap between the plate surfaces.
The pair of protrusions 12 is formed with a through hole 15 through which the fastening member 30 passes. The through hole 15 has a circular shape.

一対の突出部１２は、正面側から見ると、図１に示すように、上下方向に対して傾いている。また、一対の突出部１２は、一方が相対的に上側に位置し、他方が相対的に下側に位置している。相対的に上側に位置する突出部１２（以後、第一突出部１２Ｆと称する）は、ポスト接続部１１の下端から上方に一段上がった位置に設けられている。一方、相対的に下側に位置する突出部１２（以後、第二突出部１２Ｓと称する）は、ポスト接続部１１の上縁から一段下がった位置に設けられている。   When viewed from the front side, the pair of protrusions 12 is inclined relative to the vertical direction as shown in FIG. Further, one of the pair of protrusions 12 is relatively positioned on the upper side, and the other is positioned relatively lower. The projecting portion 12 (hereinafter, referred to as a first projecting portion 12F) positioned relatively upward is provided at a position one step upward from the lower end of the post connection portion 11. On the other hand, the protruding portion 12 (hereinafter referred to as a second protruding portion 12S) positioned relatively downward is provided at a position one step lower than the upper edge of the post connection portion 11.

第一突出部１２Ｆ側には、後述する締結部材３０のナット３２が配され、第二突出部１２Ｓ側には、後述する締結部材３０のボルト３１の頭部３４が配される。これにより、締結部材３０が斜めに傾いた姿勢で、ナット３２が上方に配されるから、締結部材３０の締め付け作業を斜め上方から行うことができる。   A nut 32 of a fastening member 30 described later is disposed on the side of the first projection 12F, and a head 34 of a bolt 31 of the fastening member 30 described later is disposed on the side of the second projection 12S. As a result, since the nut 32 is disposed at the upper side in a posture in which the fastening member 30 is inclined, the fastening operation of the fastening member 30 can be performed from diagonally above.

一対の突出部１２は、端子金具２０または締結部材３０の位置決めをする位置決め部１６を備えている。位置決め部１６は、突出部１２の外縁から突出部１２の板面に対して略直角方向に立った形態をなしている。位置決め部１６は、端子金具２０または締結部材３０の外縁に当接することにより、端子金具２０または締結部材３０が突出部１２の板面に沿って変位することを防ぐ（回り止めをする）。位置決め部１６は、突出部１２の外縁から外側（一対の突出部１２の対向側とは反対側）に突出している。   The pair of protrusions 12 includes positioning portions 16 for positioning the terminal fitting 20 or the fastening member 30. The positioning portion 16 is configured to stand from the outer edge of the protrusion 12 in a direction substantially perpendicular to the plate surface of the protrusion 12. The positioning portion 16 prevents the displacement of the terminal fitting 20 or the fastening member 30 along the plate surface of the projecting portion 12 by abutting on the outer edge of the terminal fitting 20 or the fastening member 30 (stops rotation). The positioning portion 16 protrudes outward from the outer edge of the protruding portion 12 (a side opposite to the opposite side of the pair of protruding portions 12).

位置決め部１６は、第一突出部１２Ｆに設けられた第一位置決め部１６Ｆと、第二突出部１２Ｓに設けられた第二位置決め部１６Ｓとを備えている。
第一位置決め部１６Ｆは、図７に示すように、第一突出部１２Ｆの下端に一対が設けられている。一対の第一位置決め部１６Ｆは、貫通穴１５を間にした両側（第一突出部１２Ｆのポスト接続部１１からの突出方向における先端側及び根元側）に配されている。一対の第一位置決め部１６Ｆのうち一方は、第一位置決め部１６Ｆの先端角部に配されている。 Positioning part 16 is provided with the 1st positioning part 16F provided in the 1st projection part 12F, and the 2nd positioning part 16S provided in the 2nd projection part 12S.
As shown in FIG. 7, a pair of first positioning portions 16F is provided at the lower end of the first projecting portion 12F. The pair of first positioning portions 16F are disposed on both sides (the tip end side and the root side in the direction in which the first projecting portion 12F protrudes from the post connection portion 11) with the through hole 15 therebetween. One of the pair of first positioning portions 16F is disposed at the end corner of the first positioning portion 16F.

第二位置決め部１６Ｓは、図３に示すように、第二突出部１２Ｓの上下両端に一対が設けられている。一対の第二位置決め部１６Ｓは、第二突出部１２Ｓのポスト接続部１１からの突出方向における先端側、略半分程度の領域に設けられている。第二位置決め部１６Ｓは、突出寸法よりも幅寸法が大きい長方形状をなしている。上下一対の第二位置決め部１６Ｓのうち上側の第二位置決め部１６Ｓは、下側の第二位置決め部１６Ｓよりも突出寸法が大きくされている（図１参照）。   As shown in FIG. 3, a pair of second positioning portions 16 </ b> S is provided at the upper and lower ends of the second projecting portion 12 </ b> S. The pair of second positioning portions 16S are provided on the tip end side in the direction of protrusion of the second protruding portion 12S from the post connection portion 11, in a region of about half. The second positioning portion 16S has a rectangular shape whose width dimension is larger than the protrusion dimension. Of the upper and lower pair of second positioning portions 16S, the upper second positioning portion 16S has a projection dimension larger than that of the lower second positioning portion 16S (see FIG. 1).

第二突出部１２Ｓの上端縁には、図３に示すように、第二位置決め部１６Ｓに隣接して凹部１７が形成されている。凹部１７は、第二突出部１２Ｓの上端縁のうち第二位置決め部１６Ｓとポスト接続部１１との段差１８によって形成された凹みである。   As shown in FIG. 3, a recess 17 is formed on the upper end edge of the second protrusion 12 </ b> S adjacent to the second positioning portion 16 </ b> S. The recess 17 is a recess formed by the step 18 between the second positioning portion 16S and the post connection portion 11 in the upper end edge of the second protrusion 12S.

締結部材３０は、図３に示すように、金属製のボルト３１及びナット３２を有している。締結部材３０の締め込み量を調整することで一対の突出部１２の間隔が増減され、ポスト接続部１１の径寸法が増減（縮径または拡径）される。締結部材３０の締め付け量を調整することにより、バッテリポストＰに対してポスト接続部１１を適切な接続状態に保持することができる。   The fastening member 30 has a metal bolt 31 and a nut 32 as shown in FIG. By adjusting the amount of tightening of the fastening member 30, the distance between the pair of protrusions 12 is increased or decreased, and the diameter of the post connection portion 11 is increased or decreased (diameter reduction or diameter increase). By adjusting the tightening amount of the fastening member 30, the post connection portion 11 can be held in an appropriate connection state with respect to the battery post P.

ボルト３１は、軸部３３と、軸部３３の一端に設けられた頭部３４とを備えている。軸部３３は、一対の突出部１２の貫通穴１５及び端子金具２０の貫通穴２５に貫通され、頭部３４は、第二突出部１２Ｓの板面に沿って配され、軸部３３の先端部（頭部３４と反対側の端部）は、第一突出部１２Ｆを貫通した先に突出する。   The bolt 31 includes a shaft 33 and a head 34 provided at one end of the shaft 33. The shaft 33 passes through the through holes 15 of the pair of protrusions 12 and the through holes 25 of the terminal fitting 20, and the head 34 is disposed along the plate surface of the second protrusion 12 S. The portion (the end opposite to the head 34) protrudes forward through the first protrusion 12F.

ボルト３１の頭部３４は、全体として略正方形の厚板状をなしている。頭部３４は、第二突出部１２Ｓの板面の概ね全体を覆う大きさを備えている。頭部３４の外周面（上下両面）は、第二位置決め部１６Ｓに近接して配され、これによりボルト３１は回転を規制される。   The head 34 of the bolt 31 has a generally square plate shape as a whole. The head 34 has a size that covers substantially the entire plate surface of the second protrusion 12S. The outer peripheral surface (upper and lower surfaces) of the head portion 34 is disposed close to the second positioning portion 16S, whereby the rotation of the bolt 31 is restricted.

ナット３２は、外周が六角形状をなすものであり、内側にネジ孔が貫通して形成されている。ナット３２は、軸部３３の先端側に螺合されている。
ナット３２と第一突出部１２Ｆとの間にはワッシャ３５が挟まれている。ワッシャ３５は方形状をなし、ワッシャ３５の下端縁が一対の第一位置決め部１６Ｆに近接して配され、連れ回りが防止される。 The outer periphery of the nut 32 has a hexagonal shape, and a screw hole is formed through the inner side. The nut 32 is screwed on the tip end side of the shaft portion 33.
A washer 35 is sandwiched between the nut 32 and the first protrusion 12F. The washer 35 has a square shape, and the lower end edge of the washer 35 is disposed in the vicinity of the pair of first positioning portions 16F to prevent corotation.

The terminal fitting 20 includes a wire barrel portion 24A for crimping the exposed conductor at the end portion of the wire W, and an insulation barrel portion 24B for crimping the insulation coating.

本実施例のバッテリ端子Ｔは、図３に示すように、２つの端子金具２０を備えている。２つの端子金具２０のうち一方の端子金具（以後、第一端子金具２０Ｆと称する）は相対的に大型であり、他方の端子金具（以後、第二端子金具２０Ｓと称する）は相対的に小型とされている。第一端子金具２０Ｆは相対的に太い電線Ｗの端末部に接続され、第二端子金具２０Ｓは、相対的に細い電線Ｗの端末部に接続されるものである。第二端子金具２０Ｓは、例えばフュージブルリンクから引き出された細物電線に接続されるＦＬ用端子金具である。   As shown in FIG. 3, the battery terminal T of the present embodiment includes two terminal fittings 20. Of the two terminal fittings 20, one of the terminal fittings (hereinafter referred to as the first terminal fitting 20F) is relatively large, and the other terminal fitting (hereinafter referred to as the second terminal fitting 20S) is relatively small. It is assumed. The first terminal fitting 20F is connected to the end portion of the relatively thick wire W, and the second terminal fitting 20S is connected to the end portion of the relatively thin wire W. The second terminal fitting 20S is, for example, a terminal fitting for FL connected to a fine wire drawn from the fusible link.

第一端子金具２０Ｆは、端子側接続部２１、屈曲部２３及び基板部２６が概ね同等の幅寸法（端子金具２０の長手方向に対し横方向の寸法）を有している。第一端子金具２０Ｆの端子側接続部２１の下端には、一対の第一位置決め部１６Ｆの間に嵌る幅寸法を有する段差突部２８が突出して設けられている（図１０参照）。第一端子金具２０Ｆの電線Ｗは、屈曲部２３の曲げの外側に圧着されている。   In the first terminal fitting 20F, the terminal-side connection portion 21, the bending portion 23, and the substrate portion 26 have substantially the same width dimensions (dimensions in the lateral direction with respect to the longitudinal direction of the terminal fitting 20). At the lower end of the terminal-side connection portion 21 of the first terminal fitting 20F, a step protrusion 28 having a width that fits between the pair of first positioning portions 16F is provided to protrude (see FIG. 10). The electric wire W of the first terminal fitting 20F is crimped to the outside of the bending of the bending portion 23.

第二端子金具２０Ｓは、図３に示すように、端子側接続部２１に対して屈曲部２３及び基板部２６の幅寸法が小さくされている。第二端子金具２０Ｓの屈曲部２３及び基板部２６は、端子側接続部２１の幅方向における一端側に寄った位置に配されている。第二端子金具２０Ｓの屈曲部２３は、第二突出部１２Ｓの凹部１７に対応する幅寸法とされている。第二端子金具２０Ｓの電線Ｗは、屈曲部２３の曲げの内側に圧着されている。   As shown in FIG. 3, in the second terminal fitting 20 </ b> S, the width dimension of the bent portion 23 and the substrate portion 26 is smaller than that of the terminal side connection portion 21. The bent portion 23 and the substrate portion 26 of the second terminal fitting 20S are disposed at a position closer to one end side in the width direction of the terminal side connection portion 21. The bent portion 23 of the second terminal fitting 20S has a width that corresponds to the recess 17 of the second projecting portion 12S. The electric wire W of the second terminal fitting 20S is crimped to the inside of the bending of the bending portion 23.

なお、第一端子金具２０Ｆ及び第二端子金具２０Ｓは、端子側接続部２１の大きさが同等であり、電線側接続部２２の長さ寸法及び幅寸法については第一端子金具２０Ｆが第二端子金具２０Ｓより大きくされている。   The first terminal metal fitting 20F and the second terminal metal fitting 20S have the same size of the terminal side connection portion 21, and the first terminal metal fitting 20F is the second one for the length dimension and the width dimension of the electric wire side connection portion 22. It is larger than the terminal fitting 20S.

次に、本実施例のバッテリ端子ＴをバッテリポストＰに取り付ける作業の一例を説明する。
まず、図１に示すように、ポスト接続部１１をバッテリポストＰに嵌合する。このとき、端子本体部１０に端子金具２０を取り付けた状態にしておく。すなわち、一対の突出部１２及び電線Ｗの端末部に圧着された状態の端子金具２０に締結部材３０を貫通しておく。第一端子金具２０Ｆの端子側接続部２１は、一対の突出部１２の間に入れた状態にし、第二端子金具２０Ｓの端子側接続部２１は、第二突出部１２Ｓとボルト３１の頭部３４との間に入れた状態にして締結部材３０を貫通させ緩く締める。このとき、ポスト接続部１１は拡径状態であり、バッテリポストＰに上方から嵌め入れることができる。 Next, an example of an operation of attaching the battery terminal T of the present embodiment to the battery post P will be described.
First, as shown in FIG. 1, the post connection portion 11 is fitted to the battery post P. At this time, the terminal fitting 20 is attached to the terminal main body 10. That is, the fastening member 30 is penetrated through the terminal fitting 20 in a state of being crimped to the pair of projecting portions 12 and the end portion of the electric wire W. The terminal side connection portion 21 of the first terminal fitting 20F is placed between the pair of projecting portions 12, and the terminal side connecting portion 21 of the second terminal fitting 20S is the head of the second projecting portion 12S and the bolt 31. Then, the fastening member 30 is penetrated and loosely tightened. At this time, the post connection portion 11 is in a state of diameter expansion, and can be fitted into the battery post P from above.

次に、締結部材３０を締め付ける。ナット３２を回転させると、一対の突出部１２が次第に接近する。このとき、一対の突出部１２の間に第一端子金具２０Ｆの端子側接続部２１が挟まれるから、突出部１２の過度のたわみを防ぐことができる。最終的には、図２に示すように、突出部１２の板面と端子側接続部２１の板面とが、面あたりした状態になる。すなわち第一端子金具２０Ｆの端子側接続部２１は、第一突出部１２Ｆ及び第二突出部１２Ｓの間に挟まれて両突出部１２の板面に面当たりする。第二端子金具２０Ｓの端子側接続部２１は、第二突出部１２Ｓとボルト３１の頭部３４との間に挟まれて第二突出部１２Ｓ及びボルト３１の頭部３４に面当たりする。こうして、端子側接続部２１と突出部１２とが面接触することにより、端子本体部１０と端子金具２０とが電気的に接続された状態になる。また、縮径変形したポスト接続部１１は、バッテリポストＰの外周面に面接触状態で密着し、バッテリポストＰに対して導通可能に接続された状態で固定される。
以上により、バッテリ端子ＴをバッテリポストＰに取り付ける作業が完了する。 Next, the fastening member 30 is tightened. As the nut 32 is rotated, the pair of protrusions 12 gradually approaches. At this time, since the terminal-side connection portion 21 of the first terminal fitting 20F is sandwiched between the pair of protrusions 12, excessive deflection of the protrusions 12 can be prevented. Finally, as shown in FIG. 2, the plate surface of the protruding portion 12 and the plate surface of the terminal-side connection portion 21 come into surface contact. That is, the terminal-side connecting portion 21 of the first terminal fitting 20F is sandwiched between the first projecting portion 12F and the second projecting portion 12S and comes into surface contact with the plate surfaces of the both projecting portions 12. The terminal-side connection portion 21 of the second terminal fitting 20S is sandwiched between the second protrusion 12S and the head 34 of the bolt 31 and comes into surface contact with the second protrusion 12S and the head 34 of the bolt 31. Thus, the terminal-side connecting portion 21 and the projecting portion 12 are in surface contact with each other, whereby the terminal body portion 10 and the terminal fitting 20 are electrically connected. Further, the reduced diameter deformed post connection portion 11 is in close contact with the outer peripheral surface of the battery post P in a surface contact state, and is fixed in a state of being conductively connected to the battery post P.
By the above, the work of attaching the battery terminal T to the battery post P is completed.

バッテリ端子ＴがバッテリポストＰに取り付けられた状態では、図２に示すように、第一端子金具２０Ｆ及び第二端子金具２０Ｓは、同じ向きで略平行をなして配されている。第二端子金具２０Ｓは、第一端子金具２０Ｆより低い位置に配されている。第一端子金具２０Ｆの基板部２６と第二端子金具２０Ｓの基板部２６とが互いに対向する向きとなっている。   In the state where the battery terminal T is attached to the battery post P, as shown in FIG. 2, the first terminal fitting 20F and the second terminal fitting 20S are arranged in the same direction and substantially in parallel. The second terminal fitting 20S is disposed at a lower position than the first terminal fitting 20F. The substrate portion 26 of the first terminal fitting 20F and the substrate portion 26 of the second terminal fitting 20S face each other.

また、第一端子金具２０Ｆの屈曲部２３は、第二突出部１２Ｓの上側に位置し、第二端子金具２０Ｓの屈曲部２３は、ボルト３１の頭部３４の上側に位置している。第二端子金具２０Ｓの屈曲部２３は、第二突出部１２Ｓの凹部１７の位置に配され、上側の第二位置決め部１６Ｓと同じ高さ位置に配されている。第一端子金具２０Ｆ及び第二端子金具２０Ｓの電線側接続部２２の下端は、いずれもバッテリ本体Ｂの上面より上方に位置している。電線Ｗは、電線側接続部２２に沿って斜め下方に延び、垂直方向に垂下されている。   The bent portion 23 of the first terminal fitting 20F is located on the upper side of the second protrusion 12S, and the bent portion 23 of the second terminal fitting 20S is located on the upper side of the head 34 of the bolt 31. The bent portion 23 of the second terminal fitting 20S is disposed at the position of the recess 17 of the second projecting portion 12S, and is disposed at the same height position as the upper second positioning portion 16S. The lower ends of the wire-side connection portions 22 of the first terminal fitting 20F and the second terminal fitting 20S are both located above the top surface of the battery body B. The wire W extends obliquely downward along the wire-side connection portion 22 and is suspended vertically.

次に、上記のように構成された実施例の作用および効果について説明する。
本実施例のバッテリ端子Ｔは、バッテリポストＰの外周側を包囲するとともに周方向の一部が開放された形状をなすポスト接続部１１、及びポスト接続部１１の周方向における両端から径方向の外側に突出し、締結部材３０により互いの間隔が狭められることでポスト接続部１１を縮径させる一対の突出部１２を有する端子本体部１０と、端子本体部１０とは別体であり、締結部材３０により突出部１２に締結されることで端子本体部１０と電気的に接続される端子金具２０と、を備えている。この構成によれば、端子本体部１０が、従来の電線接続部に相当する部分を備えていないから、端子本体部１０の展開形状が小さくなる。すなわち、本実施例の端子本体部１０の展開形状は、図９に示すように、ポスト接続部１１及び一対の突出部１２を構成する部分４０の長手方向中央部に、板状部１３を構成する部分４１が膨出した形状をなしている。板状部１３を構成する部分４１は、従来の電線接続部を構成する部分１０１に比して短く、また幅広な形状をなしている。よって、廃棄部分４２の面積は、バッテリ端子Ｔの端子本体部１０を構成する部分に対して小さくなっている。したがって、従来に比して歩留まりをよくすることができる。 Next, the operation and effects of the embodiment configured as described above will be described.
The battery terminal T of the present embodiment surrounds the outer peripheral side of the battery post P and has a post connection portion 11 having a shape in which a part in the circumferential direction is opened and a radial direction from both ends in the circumferential direction of the post connection portion 11 The terminal body 10 having a pair of projections 12 that project outward and reduce the diameter of the post connection 11 by narrowing the mutual spacing by the fastening members 30, and the terminal body 10 are separate members, and the fastening members A terminal fitting 20 electrically connected to the terminal main body 10 by being fastened to the projecting portion 12 by 30 is provided. According to this configuration, since the terminal body 10 does not have a portion corresponding to the conventional wire connection portion, the expanded shape of the terminal body 10 is reduced. That is, as shown in FIG. 9, the expanded shape of the terminal main body portion 10 of the present embodiment includes the plate-like portion 13 at the longitudinal central portion of the post connecting portion 11 and the portion 40 constituting the pair of projecting portions 12. The portion 41 has a bulging shape. The part 41 which comprises the plate-like-part 13 has comprised the shape which is short and wide compared with the part 101 which comprises the conventional wire connection part. Therefore, the area of the discarding portion 42 is smaller than the portion of the battery terminal T that constitutes the terminal main body 10. Therefore, the yield can be improved as compared to the prior art.

また、第一端子金具２０Ｆが、一対の突出部１２の間に挟まれている。この構成によれば、第一端子金具２０Ｆにより突出部１２の過度の撓みを規制することができ、また、接続信頼性を確保することができる。   In addition, the first terminal fitting 20F is sandwiched between the pair of protruding portions 12. According to this configuration, it is possible to restrict excessive bending of the protrusion 12 by the first terminal fitting 20F, and to secure connection reliability.

また、一対の突出部１２が、締結部材３０の位置決めをする位置決め部１６を備えている。すなわち、一対の突出部１２が、ワッシャ３５の位置決めをする第一位置決め部１６Ｆと、ボルト３１の頭部３４の位置決めをする第二位置決め部１６Ｓとを備えている。この構成によれば、締結部材３０が位置決めされるから、締結部材３０の連れ回りを防ぐことができる。   Further, the pair of projecting portions 12 are provided with positioning portions 16 for positioning the fastening member 30. That is, the pair of protrusions 12 includes a first positioning portion 16F for positioning the washer 35 and a second positioning portion 16S for positioning the head 34 of the bolt 31. According to this configuration, since the fastening member 30 is positioned, corotation of the fastening member 30 can be prevented.

また、例えば、図１０に示すように、第一端子金具２０Ｆを、第一突出部１２Ｆの外側に配置することにより、第一位置決め部１６Ｆが、第一端子金具２０Ｆを位置決めする機能を発揮する。すなわち第一端子金具２０Ｆの下端が、一対の第一位置決め部１６Ｆの上面に近接して配され、第一端子金具２０Ｆの下端の段差突部２８が、一対の第一位置決め部１６Ｆの間に嵌合することにより、第一端子金具２０Ｆは回り止めされる。このように、位置決め部１６は、端子金具２０の取り付け態様により、締結部材３０の回り止めや端子金具２０の位置決めをすることができる。   Further, for example, as shown in FIG. 10, by arranging the first terminal fitting 20F outside the first projecting portion 12F, the first positioning portion 16F exhibits the function of positioning the first terminal fitting 20F. . That is, the lower end of the first terminal fitting 20F is disposed in proximity to the upper surfaces of the pair of first positioning portions 16F, and the stepped projection 28 at the lower end of the first terminal fitting 20F is between the pair of first positioning portions 16F. By fitting, the first terminal fitting 20F is locked. Thus, the positioning portion 16 can prevent the rotation of the fastening member 30 and position the terminal fitting 20 depending on the manner in which the terminal fitting 20 is attached.
