Abstract

<P>PROBLEM TO BE SOLVED: To reduce a material cost by lessening a waste of a material when preparing the material by stamping out a metallic plate material by a press. <P>SOLUTION: In this terminal fitting for grounding Ta, a part of the metallic plate material M which has been stamped out is used as a circular main body 10, and a rotation stopping part 11 is formed by cutting, raising, and bending a part of the metallic plate material M, that is a part in the circular region of the main body 10. Since a part Md used as the rotation stopping part 11 does not protrude from the periphery of the main body 10 (Ma) in a developed state before the rotation stopping part 11 is bent, little material is wastefully consumed when stamping out the metallic plate material, in comparison with a terminal fitting formed so that a part used as the rotation stopping part 11 protrudes from the periphery of the main body. <P>COPYRIGHT: (C)2006,JPO&NCIPI

＜実施形態１＞
以下、本発明を具体化した実施形態１を図１乃至図５を参照して説明する。本実施形態１のアース用端子金具Ｔａは、所定形状に打ち抜いた平板状の金属板材Ｍ（図４を参照）を曲げ加工したものであり、接地部材Ｅ（例えば、自動車のボディ）に対して面接触状態で接触する略円板状の本体１０と、接地部材Ｅに係止されることで本体１０の回転を規制する回り止め部１１と、電線圧着部１２とを備えている。曲げ加工前の展開状態の金属板材Ｍは、本体１０及び回り止め部１１を構成する略円形部Ｍａと、略円形部Ｍａの外周から放射状に延出して電線圧着部１２を構成する延出部Ｍｂとからなる。 <Embodiment 1>
A first embodiment embodying the present invention will be described below with reference to FIGS. The ground terminal fitting Ta according to the first embodiment is obtained by bending a flat metal plate material M (see FIG. 4) punched into a predetermined shape, and with respect to a grounding member E (for example, the body of an automobile). A substantially disk-shaped main body 10 that contacts in a surface contact state, a detent portion 11 that restricts rotation of the main body 10 by being locked to the grounding member E, and a wire crimping portion 12 are provided. The unfolded metal plate M before bending includes a substantially circular portion Ma constituting the main body 10 and the rotation preventing portion 11, and an extending portion constituting the wire crimping portion 12 extending radially from the outer periphery of the substantially circular portion Ma. Mb.

略円形部Ｍａの中心には、略円形部Ｍａの外周と同心の円形をなすボルト孔１３が形成されている。また、略円形部Ｍａには、その外周から中心側へ切り込まれて更に径方向と略直角に直線状に切り込まれた形態のスリット状の切欠部Ｍｃが、周方向に間隔を空けて２箇所に形成されている。この略Ｌ字形の切欠部Ｍｃと略円形部Ｍａの外周とによって囲まれた略方形領域Ｍｄを曲げ加工することによって、回り止め部１１が形成されている。尚、略方形領域Ｍｄにおける外周側の縁部Ｍｅは、円弧形ではなく、直線状をなしている。かかる略方形領域Ｍｄは、概ね径方向の折り目に沿って下方へ略直角に曲げられ、更に、その曲げた部分を略中央位置の折り目に沿って上方へ密着折り返し状に曲げることによって、回り止め部１１が形成されている。   A bolt hole 13 is formed at the center of the substantially circular portion Ma. The bolt hole 13 is concentric with the outer periphery of the approximately circular portion Ma. In addition, the substantially circular portion Ma has slit-shaped cut portions Mc which are cut from the outer periphery to the center side and further linearly cut substantially perpendicularly to the radial direction with a space in the circumferential direction. It is formed in two places. The anti-rotation portion 11 is formed by bending a substantially rectangular region Md surrounded by the substantially L-shaped cutout portion Mc and the outer periphery of the substantially circular portion Ma. Note that the outer peripheral side edge portion Me in the substantially square region Md is not an arc shape but a linear shape. Such a substantially square region Md is bent substantially at a right angle downward along a substantially radial fold, and further, the bent portion is bent upwardly along a fold at a substantially central position so as to prevent rotation. Part 11 is formed.

電線圧着部１２は、本体１０に連なる底板１２ａの両側縁から立ち上がる一対のカシメ片１２ｂとからなるオープンバレル状をなす。この電線圧着部１２においては、底板１２ａに載置された電線（図示せず）がカシメ片１２ｂにより包み込まれるようにカシメつけられることで、導通可能に接続される。   The wire crimping portion 12 has an open barrel shape composed of a pair of caulking pieces 12b rising from both side edges of the bottom plate 12a connected to the main body 10. In the electric wire crimping portion 12, an electric wire (not shown) placed on the bottom plate 12a is caulked so as to be wrapped by the caulking piece 12b, thereby being connected so as to be conductive.

かかるアース用端子金具Ｔａの本体１０を接地部材Ｅの上面に載置するとともに、回り止め部１１を接地部材Ｅの係止孔Ｅａに嵌入し、ボルト孔１３に上から挿し込んだボルトＢを、接地部材Ｅの雌ネジ孔（図示せず）に螺合して締め付けると、アース用端子金具Ｔａが、本体１０を接地部材Ｅの上面に対して面接触状態で接触させた状態に取り付けられる。取付けに際しては、ボルトＢの鍔Ｂａが本体１０の上面に接触するため、摩擦抵抗によって本体１０がボルトＢと一緒に連れ回りしようとするのであるが、回り止め部１１が係止孔Ｅａに嵌入されているので、本体１０がボルトＢ（ボルト孔１３）を中心として回転することが規制される。これにより、電線圧着部１２に接続されている電線の導出方向が一定の方向に定められ、電線が無理に曲げられる虞はない。   The main body 10 of the ground terminal fitting Ta is placed on the upper surface of the grounding member E, and the anti-rotation part 11 is fitted into the locking hole Ea of the grounding member E, and the bolt B inserted from above into the bolt hole 13 is attached. Then, when screwed into a female screw hole (not shown) of the grounding member E and tightened, the grounding terminal fitting Ta is attached in a state where the main body 10 is brought into contact with the upper surface of the grounding member E in a surface contact state. . At the time of mounting, since the flange Ba of the bolt B contacts the upper surface of the main body 10, the main body 10 tries to rotate with the bolt B due to frictional resistance, but the anti-rotation portion 11 is inserted into the locking hole Ea. Therefore, the main body 10 is restricted from rotating around the bolt B (bolt hole 13). Thereby, the derivation | leading-out direction of the electric wire connected to the electric wire crimping part 12 is determined in the fixed direction, and there is no possibility that an electric wire may be bent forcibly.

上述のように本実施形態のアース用端子金具Ｔａは、所定形状に打ち抜いた金属板材Ｍの一部を本体１０とし、金属板材Ｍの一部を曲げ加工することによって回り止め部１１が形成されているのであるが、回り止め部１１は、本体１０の略円形領域内における一部を切り起すことによって形成されている。換言すると、本体１０に、スリット状の切欠部Ｍｃを形成し、切欠部Ｍｃに沿った領域を本体１０に対して曲げ加工することで、回り止め部１１が形成されている。したがって、回り止め部１１を曲げ加工する前の展開状態では、回り止め部１１となる略方形領域Ｍｄが円形の本体１０（略円形部Ｍａ）の外周から突出しないので、回り止め部となる部分が円形の本体の外周から突出する形態のものと比較すると、金属板材Ｍを打ち抜く際の材料の無駄が少なくて済んでいる。   As described above, in the ground terminal fitting Ta according to the present embodiment, a part of the metal plate material M punched into a predetermined shape is used as the main body 10, and the rotation preventing part 11 is formed by bending a part of the metal plate material M. However, the anti-rotation portion 11 is formed by cutting and raising a part of the main body 10 in a substantially circular region. In other words, the non-rotating portion 11 is formed by forming the slit-shaped cutout Mc in the main body 10 and bending the region along the cutout Mc with respect to the main body 10. Therefore, in the unfolded state before the anti-rotation portion 11 is bent, the substantially rectangular region Md that becomes the anti-rotation portion 11 does not protrude from the outer periphery of the circular main body 10 (substantially circular portion Ma), and thus the portion that becomes the anti-rotation portion Compared with the one in which the shape protrudes from the outer periphery of the circular main body, the waste of the material when the metal plate M is punched out can be reduced.

また、回り止め部１１の先端１１ａ（下端）は折り返し状に曲げ加工されることで略半円形をなしているので、回り止め部１１の先端（下端）に電線が接触しても、電線が傷つくことはない。   In addition, since the tip 11a (lower end) of the rotation stopper 11 is bent into a folded shape, it forms a substantially semicircular shape. It will not hurt.

＜実施形態２＞
次に、本発明を具体化した実施形態２を図６ないし図９を参照して説明する。本実施形態２のアース用端子金具Ｔｂは、所定形状に打ち抜いた平板状の金属板材Ｐを曲げ加工したものであり、接地部材Ｅ（例えば、自動車のボディ）に対して面接触状態で接触する略円板状の本体２０と、接地部材Ｅに係止されることで本体２０の回転を規制する回り止め部２１と、電線Ｗを接続するための電線圧着部２２とを備えている。曲げ加工前の展開状態の金属板材Ｐは、本体２０を構成する円形部Ｐａと、円形部Ｐａの外周から放射状に延出して電線圧着部２２を構成する延出部Ｐｂとからなる。円形部Ｐａの中心には、円形部Ｐａの外周と同心の円形をなすボルト孔２３が形成されている。 <Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The ground terminal fitting Tb according to the second embodiment is obtained by bending a flat metal plate P punched into a predetermined shape, and makes contact with the ground member E (for example, the body of an automobile) in a surface contact state. A substantially disc-shaped main body 20, a rotation preventing portion 21 that restricts rotation of the main body 20 by being locked to the grounding member E, and a wire crimping portion 22 for connecting the electric wire W are provided. The unfolded metal plate P before bending includes a circular portion Pa that constitutes the main body 20 and an extending portion Pb that radially extends from the outer periphery of the circular portion Pa to constitute the wire crimping portion 22. At the center of the circular portion Pa, a bolt hole 23 is formed that is concentric with the outer periphery of the circular portion Pa.

電線圧着部２２は、本体２０（円形部Ｐａ）に連なる底板２４と、底板２４の両側縁から立ち上がる一対のカシメ片２５とからなるオープンバレル状をなす。この電線圧着部２２においては、底板２４に載置された電線がカシメ片２５により包み込まれるようにカシメつけられることで、導通可能に接続される。この電線圧着部２２は、電線Ｗの絶縁被覆Ｗａをカシメつけるインシュレーションバレル２２ａと、電線の絶縁被覆Ｗａを剥いて露出させた芯線Ｗｂをカシメつけるワイヤバレル２２ｂとからなる。   The electric wire crimping portion 22 has an open barrel shape including a bottom plate 24 connected to the main body 20 (circular portion Pa) and a pair of crimping pieces 25 rising from both side edges of the bottom plate 24. In the electric wire crimping portion 22, the electric wires placed on the bottom plate 24 are caulked so as to be wrapped by the caulking pieces 25, so that the electric wires are connected in a conductive manner. The electric wire crimping portion 22 includes an insulation barrel 22a for caulking the insulation coating Wa of the electric wire W, and a wire barrel 22b for caulking the core wire Wb exposed by peeling off the electric insulation coating Wa of the electric wire.

金属板材Ｐの底板２４のうちインシュレーションバレル２２ａを構成する領域には、略Ｕ字形をなすスリット２６が形成され、このスリット２６によって囲まれた略方形領域２７を曲げ加工することによって、回り止め部２１が形成されている。かかる略方形領域２７は、左右方向（即ち、電線Ｗの導出方向と直角な方向であり、本体２０からの電線圧着部２２の突出方向と直角な方向）の折り目に沿って下方へ略直角に曲げられることによって、回り止め部２１を構成している。この回り止め部２１を曲げ加工することによって底板２４に形成された開口２８のうち、前側（本体２０側）の開口縁２８Ｆには回り止め部２１が連なり、後側（電線Ｗが導出される側）の開口縁２８Ｒはエッジ状をなしている。そして、このエッジ状をなう後側の開口縁２８Ｒが、電線Ｗの絶縁被覆Ｗａの外周と対応するように位置している。   A slit 26 having a substantially U shape is formed in a region constituting the insulation barrel 22a in the bottom plate 24 of the metal plate material P, and a substantially rectangular region 27 surrounded by the slit 26 is bent to prevent rotation. A portion 21 is formed. The substantially rectangular region 27 is substantially perpendicular to the lower side along the crease in the left-right direction (that is, the direction perpendicular to the lead-out direction of the wire W and the direction perpendicular to the protruding direction of the wire crimping portion 22 from the main body 20). The anti-rotation part 21 is configured by being bent. Of the opening 28 formed in the bottom plate 24 by bending the rotation preventing portion 21, the rotation preventing portion 21 is connected to the opening edge 28F on the front side (main body 20 side), and the rear side (the electric wire W is led out). The side edge 28R has an edge shape. The rear opening edge 28 </ b> R having the edge shape is positioned so as to correspond to the outer periphery of the insulating coating Wa of the electric wire W.

かかるアース用端子金具Ｔｂの本体２０を接地部材Ｅの上面に載置するとともに、回り止め部２１を接地部材Ｅの係止孔Ｅａに嵌入し、ボルト孔２３に上から挿し込んだボルト（図示せず）を、接地部材Ｅの雌ネジ孔（図示せず）に螺合して締め付けると、アース用端子金具Ｔｂが、本体２０を接地部材Ｅの上面に対して面接触状態で接触させた状態に取り付けられる。取付けに際しては、ボルトの鍔が本体２０の上面に接触するため、摩擦抵抗によって本体２０がボルトと一緒に連れ回りしようとするのであるが、回り止め部２１が係止孔Ｅａに嵌入されているので、本体２０がボルト（ボルト孔２３）を中心として回転することが規制される。これにより、電線圧着部２２に接続されている電線Ｗの導出方向が一定の方向に定められ、電線Ｗが無理に曲げられる虞はない。   The main body 20 of the grounding terminal fitting Tb is placed on the upper surface of the grounding member E, and the anti-rotation part 21 is fitted into the locking hole Ea of the grounding member E and is inserted into the bolt hole 23 from above (see FIG. When the screw 20 is screwed into a female screw hole (not shown) of the grounding member E and tightened, the grounding terminal fitting Tb brings the main body 20 into contact with the upper surface of the grounding member E in a surface contact state. Attached to the state. At the time of mounting, the bolt collar comes into contact with the upper surface of the main body 20, so that the main body 20 tries to rotate with the bolt due to frictional resistance, but the anti-rotation portion 21 is fitted in the locking hole Ea. Therefore, the main body 20 is restricted from rotating around the bolt (bolt hole 23). Thereby, the derivation | leading-out direction of the electric wire W connected to the electric wire crimping part 22 is determined in the fixed direction, and there is no possibility that the electric wire W may be bent forcibly.

上述のように本実施形態のアース用端子金具Ｔｂは、所定形状に打ち抜いた金属板材Ｐの一部を本体２０とし、金属板材Ｐの一部を曲げ加工することによって回り止め部２１が形成されているのであるが、回り止め部２１は、電線圧着部２２の底板２４を部分的に切り起すことで形成されている。したがって、回り止め部２１を曲げ加工する前の展開状態では、回り止め部２１となる略方形領域２７が電線圧着部２２となる延出部Ｐｂの外縁から突出しないので、回り止め部となる部分が電線圧着部の外縁から突出する形態のものと比較すると、金属板材Ｐを打ち抜く際の材料の無駄が少なくて済んでいる。   As described above, in the ground terminal fitting Tb of the present embodiment, a part of the metal plate material P punched into a predetermined shape is used as the main body 20, and a part of the metal plate material P is bent to form the rotation preventing portion 21. However, the rotation preventing portion 21 is formed by partially cutting and raising the bottom plate 24 of the wire crimping portion 22. Therefore, in the unfolded state before the anti-rotation portion 21 is bent, the substantially rectangular region 27 that becomes the anti-rotation portion 21 does not protrude from the outer edge of the extending portion Pb that becomes the electric wire crimping portion 22, and thus the portion that becomes the anti-rotation portion Compared with the form which protrudes from the outer edge of the electric wire crimping part, the waste of the material at the time of punching out the metal plate material P can be reduced.

また、回り止め部２１が形成された後、底板２４に開口部２８が形成されるが、底板２４における回り止め部２１の切り起し領域である略方形領域２７が電線Ｗの絶縁被覆Ｗａと対応するように配置されている。したがって、電線Ｗが後方へ引っ張られたときに、その絶縁被覆Ｗａの外周が開口部２８のエッジ状をなす後側の開口縁２８Ｒに引っ掛かるようになり、これにより、電線Ｗを抜け止めすることができる。   In addition, after the anti-rotation portion 21 is formed, an opening 28 is formed in the bottom plate 24, but the substantially rectangular region 27, which is a raised region of the anti-rotation portion 21 in the bottom plate 24, is connected to the insulation coating Wa of the wire W It is arranged to correspond. Therefore, when the electric wire W is pulled backward, the outer periphery of the insulating coating Wa is caught by the rear opening edge 28R forming the edge shape of the opening 28, thereby preventing the electric wire W from coming off. Can do.
