請求項1と2の各発明では、第1板部と第2板部とを各板部の開口にそれぞれ装着された状態で通電可能に接続するアースクリップとして、特許文献1のような従来構造に対し、金属の単一部材で成形可能なためコスト低減を図り易く、板部同士の間隔が狭くても規制され難く、通電機能も損なわれる虞がなく品質的に優れている。   In each invention of Claims 1 and 2, as a ground clip that connects the first plate portion and the second plate portion so as to be energized in a state where the first plate portion and the second plate portion are respectively attached to the openings of the respective plate portions, the conventional structure as in Patent Document 1 On the other hand, since it can be molded with a single metal member, it is easy to reduce the cost, and even if the distance between the plate portions is narrow, it is difficult to be regulated, and the current-carrying function is not impaired and the quality is excellent.

また、請求項1の発明では、図3及び図4に示されるごとく、例えば切り起こし方向(傾斜方向)が異なる複数の当接片からなり、下向きの当接片と下側の係止突起とで第1板部に固定し、上向きの当接片と上側の係止突起とで第2板部に固定する。これに対し、請求項2の発明では、図7及び図8に示されるごとく当接片が各板部の対向した板表面にそれぞれ当接する形状(概略V形やW形などの形状)からなり、例えば、当接片の途中の屈曲部と下側の係止突起とで第1板部に固定し、当接片の先端部と上側の係止突起とで第2板部に固定する。これらは、特に、板部同士の間隔Lに対し、請求項1では当接片同士の切り起こし方向と角度、請求項2では当接片の形状設定だけで対処可能となり、間隔Lが1mm以下と狭くなる場合も容易に充足できる。   Further, in the first aspect of the invention, as shown in FIGS. 3 and 4, for example, it is composed of a plurality of abutting pieces having different cut-and-raised directions (inclination directions), a downward abutting piece and a lower locking projection. And fixed to the second plate portion with the upward contact piece and the upper locking projection. On the other hand, in the invention of claim 2, as shown in FIGS. 7 and 8, the contact pieces are in contact with the opposing plate surfaces of the plate portions (shapes such as V shape and W shape). For example, the bent portion in the middle of the contact piece and the lower locking projection are fixed to the first plate portion, and the distal end portion of the contact piece and the upper locking projection are fixed to the second plate portion. In particular, with respect to the distance L between the plate portions, these can be dealt with only by setting the direction and angle of the abutting pieces in claim 1 and by setting the shape of the abutting pieces in claim 2, and the distance L is 1 mm or less. Even if it becomes narrow, it can be satisfied easily.

The peeling action with respect to the insulating paint and film which are made can also be acquired favorably.

請求項4の発明では、当接片が途中に設けられた屈曲部を有し、屈曲部と先端縁とが各板部の対向した板表面にそれぞれ当接するため、上記したような板部同士の間隔Lが狭い仕様に好適となり、剥離作用も維持されて高品質化が図られる。   In the invention of claim 4, the abutting piece has a bent portion provided in the middle, and the bent portion and the tip edge abut against the opposing plate surfaces of each plate portion. This is suitable for specifications with a narrow interval L, and the peeling action is also maintained to improve the quality.

請求項5の発明では、筒状本体が板材の両側部を突起と係合穴との嵌め合いにより筒形状に保持されているため、例えばプレス工程で板状態で形状出しした後、折り曲げ工程を経るだけで容易に製造可能となる。   In the invention of claim 5, since the cylindrical main body is held in a cylindrical shape by fitting the both sides of the plate material with the projections and the engagement holes, for example, after forming in a plate state by a pressing process, the bending process is performed. It can be easily manufactured just by passing.

請求項6の発明では、前記係止突起が筒状本体に切り起こしにより設けられているため全体が容易に一体成形可能となる。   In the invention of claim 6, since the locking projection is provided by cutting and raising the cylindrical main body, the whole can be easily formed integrally.

請求項7の発明では、前記係止突起が第1板部に対し切欠部に挿入した後、回転することで抜け止め可能となるため、各形態のごとく第1板部の外への突出寸法を抑え易く、また回転により板表面に施されている絶縁性の塗料や被膜に対する良好な剥離作用を付与できる。   In the seventh aspect of the invention, since the locking projection is inserted into the cutout portion with respect to the first plate portion, and can be prevented from coming off by rotating, the projecting dimension to the outside of the first plate portion as in each embodiment. In addition, it is possible to impart a good peeling action to the insulating paint or coating applied to the plate surface by rotation.

請求項8の発明では、請求項7において、係止突起を切欠部に挿入して回転した状態で凹部及び凸部が係合されて回転規制するため装着状態を確実に維持できる。   In the eighth aspect of the present invention, in the seventh aspect, since the concave and convex portions are engaged and restricted in rotation while the locking projection is inserted into the notch and rotated, the mounting state can be reliably maintained.

(用途)各形態のアースクリップ7又7Aは、電気的接続を可能とするため金属製の部材からなり、第1板部8と第2板部9とを、各板部8,9に設けられた開口8a,9aにそれぞれ装着された状態で通電可能に接続するものである。ここで、第1板部8としては、例えばテレビなどの電気機器の筐体を構成しているバックシャーシ又はそれに類似した板部、自動車などの車体を構成している各種パネル又はそれに類似した板部などである。第2板部9としては、例えば電気機器の筐体に内蔵される配線基板又はそれに類似した板部、車体に組み込まれている配線基板又はそれに類似した板部である。第1板部8と第2板部9とは所定の間隔を保って配置される関係である。通常は、第1板部8と第2板部9とが複数のアースクリップ7又7Aにより通電可能に接続される。開口8a,9aはほぼ同じ大きさの円形に貫通されている。第1板部8は、開口8aの内周に連設された一対の切欠部8bと、開口8aの内周にあって外面に突設されている一対の凸部8cとを有している。各切欠部8bは断面が略半円状で互いに対向している。各凸部8cは略半球状であり互いに対向している。 (Use) Each form of the earth clip 7 or 7A is made of a metal member to enable electrical connection, and the first plate portion 8 and the second plate portion 9 are provided on the plate portions 8 and 9, respectively. In such a state that the openings 8a and 9a are attached to each other, they are connected so as to be energized. Here, as the first plate portion 8, for example, a back chassis constituting a housing of an electric device such as a television or a similar plate portion, various panels constituting a vehicle body such as an automobile, or a similar plate Department. As the 2nd board part 9, it is a wiring board built in the housing | casing of an electric equipment, or a board part similar to it, a wiring board built in the vehicle body, or a board part similar to it, for example. The 1st board part 8 and the 2nd board part 9 are the relationship arrange | positioned keeping a predetermined space | interval. Usually, the 1st board part 8 and the 2nd board part 9 are connected by the some earth clip 7 or 7A so that electricity supply is possible. The openings 8a and 9a are penetrated in a circle having substantially the same size. The first plate portion 8 has a pair of cutout portions 8b provided continuously on the inner periphery of the opening 8a, and a pair of convex portions 8c provided on the inner periphery of the opening 8a and projecting on the outer surface. . Each notch 8b has a substantially semicircular cross section and faces each other. Each convex part 8c is substantially hemispherical and faces each other.

(第1形態)このアースクリップ7は、リン青銅板などのバネ弾性を有する成形体であり、筒状本体1と、筒状本体1の周面に切り起こされた複数の当接片2,3と、筒状本体1を各板部8,9の開口8a,9aにそれぞれ挿入した状態で当接片2,3と協働して固定可能にする係止手段としての係止突起5,6とを備えている。 (First Form) This ground clip 7 is a molded body having spring elasticity, such as a phosphor bronze plate, and includes a cylindrical main body 1 and a plurality of contact pieces 2 cut and raised on the peripheral surface of the cylindrical main body 1. 3 and locking protrusions 5 as locking means that can be fixed in cooperation with the contact pieces 2 and 3 in a state where the cylindrical main body 1 is inserted into the openings 8a and 9a of the plate portions 8 and 9, respectively. 6 is provided.

まず、筒状本体1は、全体が細長い略円筒であり、上端側が端部に向かって次第に径小となるテーパー部1aとなっている。この製法は、例えば、原板がプレス加工により設計形状にトリミングされた展開状態から、二次加工により折り曲げられると共に両側部に設けられた突起14と係合穴15との嵌め合いにより製品形状に保持される。係合穴15は、図3に示されるごとく外側開口幅が奥側開口幅より狭くなった蟻溝形状となっていて、突起14が一旦嵌められると外れ難くなっている。   First, the cylindrical main body 1 is a substantially cylindrical shape that is long and thin, and the upper end side is a tapered portion 1a that gradually decreases in diameter toward the end portion. In this manufacturing method, for example, from a developed state where the original plate is trimmed to a design shape by pressing, the product is bent by secondary processing and held in the product shape by fitting the projections 14 and the engagement holes 15 provided on both sides. Is done. The engagement hole 15 has a dovetail shape in which the outer opening width is narrower than the inner opening width as shown in FIG. 3, and is difficult to come off once the protrusion 14 is fitted.

当接片2,3は、図2及び図3に示されるごとくそれぞれ周囲を等分するよう2つづつ合計4つの構成である。但し、当接片2,3としては、各1つづつ合計2つの構成、或いは各3づつ合計6つの構成、更に多数で構成してもよい。また、当接片2及び当接片3は、原板にコ形状のスリットを刻印した後、切り起こしにより形成されている点で同じであるが、コ形状のスリットの向きが反対に設定されている。つまり、各当接片2は、基端部が下側、先端(自由端)が下向きに傾斜し、傾斜方向が下向きの構成となっている。各当接片3は、基端部が上側、先端(自由端)が上向きに傾斜し、傾斜方向が当接片2と逆つまり上向きの構成となっている。   As shown in FIGS. 2 and 3, the contact pieces 2, 3 have a total of four configurations, two each so as to equally divide the periphery. However, the contact pieces 2 and 3 may be configured by a total of two configurations, one by one, or a total of six configurations by each three, and more. Further, the contact piece 2 and the contact piece 3 are the same in that they are formed by cutting and raising after stamping a U-shaped slit on the original plate, but the direction of the U-shaped slit is set to be opposite. Yes. That is, each contact piece 2 is configured such that the base end portion is inclined downward, the distal end (free end) is inclined downward, and the inclination direction is downward. Each contact piece 3 is configured such that the base end portion is inclined upward and the distal end (free end) is inclined upward, and the inclination direction is opposite to the contact piece 2, that is, upward.

また、当接片2及び当接片3は逆向きに傾斜している。そして、当接片2の先端は図2(b)のごとく第2板部9と対向している第1板部8の板表面に先端下縁で線接触し、当接片3の先端は図3(b)のごとく第1板部8と対向している第2板部9の板表面に先端上縁で線接触し、それにより各板部の板表面に施されている絶縁性塗膜や被膜を剥離し易くなっている。更に、第1板部8と第2板部9とは間隔Lを保って配置されている。この間隔Lは、当接片2の先端下縁と当接片3の先端上縁との間の距離にほぼ対応している。なお、符号10は当接片2が90度以上切り起こされることで出来た穴部、符号11は当接片3が90度以上切り起こされることでできた穴部である。この例では、当接片2が当接片3よりも長く設定されている関係で、穴部10が穴部11より大きくなっている。   Further, the contact piece 2 and the contact piece 3 are inclined in opposite directions. The tip of the contact piece 2 is in line contact with the plate surface of the first plate portion 8 facing the second plate portion 9 at the lower edge of the tip as shown in FIG. As shown in FIG. 3B, an insulating coating is applied to the plate surface of the second plate portion 9 facing the first plate portion 8 at the top edge of the second plate portion 9 and thereby the plate surface of each plate portion. It is easy to peel off the film or coating. Furthermore, the 1st board part 8 and the 2nd board part 9 are arrange | positioned with the space | interval L maintained. This interval L substantially corresponds to the distance between the lower end edge of the contact piece 2 and the upper end edge of the contact piece 3. Reference numeral 10 denotes a hole formed by cutting and raising the contact piece 2 by 90 degrees or more, and reference numeral 11 denotes a hole formed by cutting and raising the contact piece 3 by 90 degrees or more. In this example, the hole 10 is larger than the hole 11 because the contact piece 2 is set longer than the contact piece 3.

係止突起5,6は筒状本体1が各板部の開口8a,9aにそれぞれ挿入された状態で、係止突起6が当接片2と協働して第1板部8に固定可能となり、係止突起5が当接片3と協働して第2板部9に固定可能となる。すなわち、係止突起5,6は図2及び図3に示されるごとくそれぞれ周囲を等分するよう2つづつ設けられている。但し、係止突起5,6は各1つづつの構成、或いは各3づつの構成、更に多数で構成してもよい。   The locking projections 5 and 6 can be fixed to the first plate portion 8 in cooperation with the contact piece 2 in a state where the cylindrical main body 1 is inserted into the openings 8a and 9a of the respective plate portions. Thus, the locking projection 5 can be fixed to the second plate portion 9 in cooperation with the contact piece 3. That is, as shown in FIG. 2 and FIG. 3, two locking projections 5 and 6 are provided so as to equally divide the periphery. However, the latching protrusions 5 and 6 may be composed of one each, three each, or a larger number.

係止突起5は、各当接片3の真上にあって、コ形状のスリット13を介して揺動可能に区画形成されており、上側の基部から下に行くに従って次第に外へ拡径した弾性片状となっている。この先端部5aは自由端側であり、筒外側からスリット13ないしは筒状本体内に屈曲されている。係止突起6は、筒状本体1の下端周囲の一部をスリット12により区画しかつ径方向に突出形成したものであり、当接片2と当接片3との間に位置している。係止突起6の上面には凹部6aが設けられている。凹部6aは、第1板部8の凸部8cが係合することで、第1板部8に対するアースクリップ7の不用意な回転が阻止される。   The locking projections 5 are directly above each contact piece 3 and are formed so as to be swingable through a U-shaped slit 13 and gradually increase in diameter toward the bottom from the upper base. It is an elastic piece. The tip 5a is on the free end side and is bent into the slit 13 or the cylindrical main body from the outside of the cylinder. The locking projection 6 is formed by dividing a part around the lower end of the cylindrical main body 1 with a slit 12 and projecting in the radial direction, and is located between the contact piece 2 and the contact piece 3. . A recess 6 a is provided on the upper surface of the locking projection 6. The concave portion 6 a is prevented from inadvertently rotating the ground clip 7 with respect to the first plate portion 8 by engaging the convex portion 8 c of the first plate portion 8.

(作動)まず、第1板部8と第2板部9とをアースクリップ7により通電可能に接続するときの操作例を説明する。この操作では、アースクリップ7を第1板部8に装着した後、第2板部9をアースクリップ7に装着することが好ましい。アースクリップ7は、図1から図3に示されるごとく、各係止突起6が対応する切欠部8b上に位置合わせされ、その状態から筒状本体1が開口8aに差し込まれると共に略90度回転操作される。すると、アースクリップ7は、下向きに傾斜した当接片2の先端と係止突起6との間に挟み込まれた状態で第1板部8に対し装着固定され、かつ、第1板部側の凸部8cと係止突起側凹部6aとが係合して回り止めされる。なお、前記回転操作では、凸部8cと凹部6aとがクリック音を伴って係合するため、回転不足や過剰に回転するということがなくなる。 (Operation) First, an operation example when the first plate portion 8 and the second plate portion 9 are connected by the ground clip 7 so as to be energized will be described. In this operation, it is preferable to attach the second plate portion 9 to the ground clip 7 after the ground clip 7 is attached to the first plate portion 8. As shown in FIGS. 1 to 3, the ground clip 7 is positioned on the corresponding notch 8 b so that each locking projection 6 is aligned, and from this state, the cylindrical body 1 is inserted into the opening 8 a and rotated approximately 90 degrees. Operated. Then, the ground clip 7 is attached and fixed to the first plate portion 8 in a state of being sandwiched between the tip of the contact piece 2 inclined downward and the locking projection 6, and on the first plate portion side. The convex portion 8c and the locking projection side concave portion 6a are engaged to be prevented from rotating. In the rotation operation, since the convex portion 8c and the concave portion 6a are engaged with each other with a click sound, there is no case of insufficient rotation or excessive rotation.

次に、第2板部9は、第1板部8上に起立されたアースクリップ7に対し開口9aが筒状本体1上に位置合わせされ、その状態から第1板部8に近づくよう移動操作される。すると、アースクリップ7は、係止突起5が開口9aの内周から受ける押圧力により縮径方向に弾性変位し、かつ、開口9aをほぼ通過すると同時に拡径方向に弾性復元する。その結果、第2板部9は、上向きに傾斜した当接片3の先端と係止突起側の先端部5aとの間に挟み込まれた状態でアースクリップ7に対し装着固定され、かつ、第1板部8に対し間隔Lを持って保持される。   Next, the second plate portion 9 is moved so that the opening 9 a is aligned on the cylindrical body 1 with respect to the ground clip 7 standing on the first plate portion 8 and approaches the first plate portion 8 from this state. Operated. Then, the ground clip 7 is elastically displaced in the diameter-reducing direction by the pressing force received by the locking projection 5 from the inner periphery of the opening 9a, and is elastically restored in the diameter-enlarging direction at the same time as substantially passing through the opening 9a. As a result, the second plate portion 9 is mounted and fixed to the ground clip 7 while being sandwiched between the tip of the contact piece 3 inclined upward and the tip 5a on the locking projection side, and The one plate portion 8 is held with an interval L.

従って、以上のアースクリップ7は、金属の単一部材からなるためコスト低減を図り易く、板部同士の間隔が狭くても規制され難く、通電機能も損なわれる虞がない。また、アースクリップ7は、当接片2,3がその切り起こし方向(傾斜方向)を異なるよう設定されるだけで、例えば、下向きの当接片2と下側の係止突起6とで第1板部8に装着固定でき、上向きの当接片3と上側の係止突起5とで第2板部9に装着固定できる。   Therefore, since the above earth clip 7 is made of a single metal member, it is easy to reduce the cost, and even if the interval between the plate portions is narrow, it is difficult to be regulated, and there is no possibility that the energization function is impaired. In addition, the ground clip 7 is set so that the contact pieces 2 and 3 have different cut-and-raised directions (inclination directions). For example, the ground clip 7 includes a downward contact piece 2 and a lower locking projection 6. It can be attached and fixed to the first plate portion 8 and can be attached and fixed to the second plate portion 9 by the upward contact piece 3 and the upper locking projection 5.

そして、この構造では、重要な点として、板部8と板部9との間隔Lが変更されたり、狭くなっても当接片2,3同士の切り起こし方向と角度の設定だけで対処可能となり、間隔Lが1mm以下(例えば0.5〜0.3mm)と狭くなる場合も容易に充足できることである。また、この構造では、各当接片2,3の先端縁が各板部8,9の板表面に所定の傾斜角で当接するため、更に第1板部8に固定する際にアースクリップ7を回転するため、各板部8,9の板表面に施されている絶縁性の塗料や被膜に対する剥離作用も良好に得られる。   In this structure, as an important point, even if the distance L between the plate portion 8 and the plate portion 9 is changed or narrowed, it can be dealt with only by setting the direction and angle between the contact pieces 2 and 3. Thus, even when the distance L becomes narrower than 1 mm (for example, 0.5 to 0.3 mm), it can be easily satisfied. Further, in this structure, since the leading edge of each contact piece 2, 3 contacts the plate surface of each plate portion 8, 9 at a predetermined inclination angle, the ground clip 7 is further fixed when being fixed to the first plate portion 8. Therefore, it is possible to obtain a good peeling action on the insulating paint or coating applied to the plate surfaces of the plate portions 8 and 9.

(第2形態)図5〜図8に示した第2形態において、第1形態と同一又は類似する箇所には極力同じ符号を付して説明する。このアースクリップ7Aは、リン青銅板などのバネ弾性を有する成形体であり、筒状本体1と、筒状本体1の周面に切り起こされて各板部8,9の対向した板表面にそれぞれ当接する少なくとも1つの当接片4と、筒状本体1を各板部8,9の開口8a,9aにそれぞれ挿入した状態で当接片4の各部と協働して固定可能にする係止手段としての係止突起5,6とを備えている。 (2nd form) In the 2nd form shown in FIGS. 5-8, the same code | symbol is attached | subjected and demonstrated to the location which is the same as that of a 1st form, or similar. This earth clip 7A is a molded body having spring elasticity such as a phosphor bronze plate, and is cut and raised on the peripheral surface of the cylindrical main body 1 and the cylindrical main body 1 and on the plate surfaces facing each of the plate portions 8 and 9. At least one abutting piece 4 that abuts each other, and a member that can be fixed in cooperation with each part of the abutting piece 4 in a state in which the cylindrical main body 1 is inserted into the openings 8a and 9a of the plate parts 8 and 9, respectively. Locking projections 5 and 6 are provided as stopping means.

まず、筒状本体1は、全体が細長い略円筒であり、上端側が端部に向かって次第に径小となるテーパー部1aとなっている。この製法は、第1形態で述べた通り、原板がプレス加工により設計形状にトリミングされた展開状態から、二次加工により折り曲げられると共に両側部に設けられた突起14と係合穴15との嵌め合いにより製品形状に保持される。係合穴15は、図6に示されるごとく外側開口幅が奥側開口幅より狭くなった蟻溝形状となっていて、突起14が一旦嵌められると外れ難くなっている。   First, the cylindrical main body 1 is a substantially cylindrical shape that is long and thin, and the upper end side is a tapered portion 1a that gradually decreases in diameter toward the end portion. In this manufacturing method, as described in the first embodiment, from the developed state where the original plate is trimmed to the design shape by press working, it is bent by secondary processing, and the projections 14 provided on both sides and the engagement holes 15 are fitted. The product shape is held by mating. The engagement hole 15 has a dovetail shape in which the outer opening width is narrower than the inner opening width as shown in FIG. 6, and is difficult to be removed once the protrusion 14 is fitted.

当接片4は、図5及び図6に示されるごとく周囲を等分している2つの構成である。但し、当接片4としては、1つの構成、或いは3以上の構成でもよい。また、当接片4は、原板にコ形状のスリットを刻印した後、切り起こしなどにより形成されて、基端部4aと先端部4bとの途中に設けられた屈曲部4cを有し、屈曲部4cの角と先端部4bの端縁とが各板部8,9の対向した板表面にそれぞれ当接するようになっている。   The contact piece 4 has two configurations that equally divide the periphery as shown in FIGS. 5 and 6. However, the contact piece 4 may have one configuration or three or more configurations. Further, the contact piece 4 is formed by cutting and raising after stamping a U-shaped slit on the original plate, and has a bent portion 4c provided in the middle of the base end portion 4a and the tip end portion 4b. The corners of the portion 4c and the edge of the tip portion 4b are in contact with the opposing plate surfaces of the plate portions 8 and 9, respectively.

すなわち、この当接片4は、基端部4a及び先端部4bが屈曲部4cを介して異方向に傾斜されている。詳述すると、基端部4aは下向きに傾斜されている。先端部4bは略V形の屈曲部4cを介して上向きに傾斜されている。そして、当接片4は、図6(b)のごとく屈曲部4cが第2板部9と対向している第1板部8の板表面に線接触し、先端部4bが第1板部8と対向している第2板部9の板表面に先端上縁で線接触し、それにより各板部の板表面に施されている絶縁性塗膜や被膜を剥離し易くなっている。更に、第1板部8と第2板部9とは間隔Lを保って配置されている。この間隔Lは、当接片4のうち、先端部4bの下縁と屈曲部4cの角との間の距離にほぼ対応している。なお、符号10aは当接片4が90度以上切り起こされることで出来た穴部である。   That is, the abutting piece 4 has a proximal end portion 4a and a distal end portion 4b inclined in different directions via the bent portion 4c. More specifically, the base end portion 4a is inclined downward. The tip 4b is inclined upward via a substantially V-shaped bent portion 4c. As shown in FIG. 6B, the contact piece 4 is in line contact with the plate surface of the first plate portion 8 where the bent portion 4 c faces the second plate portion 9, and the tip portion 4 b is the first plate portion. 8 is in line contact with the plate surface of the second plate portion 9 facing the upper edge of the second plate portion 9, thereby making it easier to peel off the insulating coating film or coating applied to the plate surface of each plate portion. Furthermore, the 1st board part 8 and the 2nd board part 9 are arrange | positioned with the space | interval L maintained. This interval L substantially corresponds to the distance between the lower edge of the tip portion 4b and the corner of the bent portion 4c in the contact piece 4. In addition, the code | symbol 10a is a hole part which the contact piece 4 was made by cutting and raising 90 degrees or more.

係止突起5,6は筒状本体1が各板部の開口8a,9aにそれぞれ挿入された状態で、係止突起6が当接片4の屈曲部4cと協働して第1板部8に固定可能となり、係止突起5が当接片4の先端部4bと協働して第2板部9に固定可能となる。すなわち、係止突起5,6は図6及び図7に示されるごとくそれぞれ周囲を等分するよう2つづつ設けられている。但し、係止突起5,6は各1つづつの構成、或いは各3づつの構成、更に多数で構成してもよい。   The locking projections 5 and 6 are the first plate portion in cooperation with the bent portion 4c of the contact piece 4 in a state in which the cylindrical main body 1 is inserted into the openings 8a and 9a of the plate portions, respectively. 8, and the locking projection 5 can be fixed to the second plate portion 9 in cooperation with the tip portion 4 b of the contact piece 4. That is, as shown in FIGS. 6 and 7, two locking projections 5 and 6 are provided so as to equally divide the periphery. However, the latching protrusions 5 and 6 may be composed of one each, three each, or a larger number.

係止突起5は、当接片4の真上にあって、コ形状のスリット13を介して揺動可能に区画形成されており、上側の基部から下に行くに従って次第に外へ拡径した弾性片状となっている。この先端部5aは自由端側であり、筒外側からスリット13ないしは筒状本体内に屈曲されている。係止突起6は、筒状本体1の下端周囲の一部をスリット12により区画しかつ径方向に突出形成したものであり、当接片4と係止突起5との間に位置している。係止突起6の上面には凹部6aが設けられている。凹部6aは、第1板部8の凸部8cが係合することで、第1板部8に対するアースクリップ7Aの不用意な回転が阻止される。   The locking projection 5 is directly above the contact piece 4 and is formed to be swingable through a U-shaped slit 13. The elastic diameter gradually increases outward from the upper base to the bottom. It is a piece. The tip 5a is on the free end side and is bent into the slit 13 or the cylindrical main body from the outside of the cylinder. The locking projection 6 is formed by dividing a part around the lower end of the cylindrical main body 1 with a slit 12 and projecting in the radial direction, and is positioned between the contact piece 4 and the locking projection 5. . A recess 6 a is provided on the upper surface of the locking projection 6. The concave portion 6 a is prevented from inadvertently rotating the ground clip 7 </ b> A with respect to the first plate portion 8 by engaging the convex portion 8 c of the first plate portion 8.

(作動)まず、第1板部8と第2板部9とをアースクリップ7Aにより通電可能に接続するときの操作例を説明する。この操作では、アースクリップ7Aを第1板部8に装着した後、第2板部9をアースクリップ7Aに装着することが好ましい。アースクリップ7Aは、図5から図7に示されるごとく、各係止突起6が対応する切欠部8b上に位置合わせされ、その状態から筒状本体1が開口8aに差し込まれると共に略90度回転操作される。すると、アースクリップ7Aは、当接片4の屈曲部4cと係止突起6との間に挟み込まれた状態で第1板部8に対し装着固定され、かつ、第1板部側の凸部8cと係止突起側凹部6aとが係合して回り止めされる。なお、前記回転操作では、凸部8cと凹部6aとがクリック音を伴って係合するため、回転不足や過剰に回転するということがなくなる。 (Operation) First, an operation example when the first plate portion 8 and the second plate portion 9 are connected to be energized by the ground clip 7A will be described. In this operation, it is preferable to attach the second plate portion 9 to the ground clip 7A after attaching the ground clip 7A to the first plate portion 8. As shown in FIGS. 5 to 7, the ground clip 7A is positioned on the corresponding notch 8b, and the cylindrical body 1 is inserted into the opening 8a and rotated approximately 90 degrees. Operated. Then, the ground clip 7A is attached and fixed to the first plate portion 8 while being sandwiched between the bent portion 4c of the contact piece 4 and the locking projection 6, and the convex portion on the first plate portion side. 8c and the latching protrusion side recessed part 6a engage, and are prevented from rotating. In the rotation operation, since the convex portion 8c and the concave portion 6a are engaged with each other with a click sound, there is no case of insufficient rotation or excessive rotation.

次に、第2板部9は、第1板部8上に起立されたアースクリップ7Aに対し開口9aが筒状本体1上に位置合わせされ、その状態から第1板部8に近づくよう移動操作される。すると、アースクリップ7Aは、係止突起5が開口9aの内周から受ける押圧力により縮径方向に弾性変位し、かつ、開口9aをほぼ通過すると同時に拡径方向に弾性復元する。その結果、第2板部9は、屈曲部4cの角と係止突起側の先端部5aとの間に挟み込まれた状態でアースクリップ7Aに対し装着固定され、かつ、第1板部8に対し間隔Lを持って保持される。   Next, the second plate portion 9 is moved so that the opening 9a is aligned on the cylindrical main body 1 with respect to the ground clip 7A standing on the first plate portion 8, and approaches the first plate portion 8 from this state. Operated. Then, the ground clip 7A is elastically displaced in the diameter reducing direction by the pressing force received by the locking projection 5 from the inner periphery of the opening 9a, and is elastically restored in the diameter increasing direction at the same time as it substantially passes through the opening 9a. As a result, the second plate portion 9 is attached and fixed to the ground clip 7A while being sandwiched between the corner of the bent portion 4c and the distal end portion 5a on the locking projection side, and is attached to the first plate portion 8. On the other hand, it is held with an interval L.

従って、以上のアースクリップ7Aは、第1形態と同じく、金属の単一部材からなるためコスト低減を図り易く、板部同士の間隔が狭くても規制され難く、通電機能も損なわれる虞がない。また、アースクリップ7Aは、当接片4を構成している屈曲部4c及び先端部4bがその傾斜方向を異なるよう設定されるだけで、例えば、屈曲部4cと下側の係止突起6とで第1板部8に装着固定でき、先端部4bと上側の係止突起5とで第2板部9に装着固定できる。   Therefore, as in the first embodiment, the above-described ground clip 7A is made of a single metal member, so that it is easy to reduce the cost, and it is difficult to be regulated even if the interval between the plate portions is narrow, and there is no possibility that the energization function is not impaired. . Further, the ground clip 7A is configured such that the bent portion 4c and the tip end portion 4b constituting the contact piece 4 are set to have different inclination directions, for example, the bent portion 4c and the lower locking projection 6 Thus, it can be mounted and fixed to the first plate portion 8, and can be mounted and fixed to the second plate portion 9 by the tip portion 4 b and the upper locking projection 5.

そして、この構造でも重要な点として、板部8と板部9との間隔Lが変更されたり、狭くなっても当接片4を構成している屈曲部4cや先端部4bの傾きないしは傾斜角の設定だけで対処可能となり、間隔Lが1mm以下(例えば0.5〜0.3mm)と狭くなる場合も容易に充足できることである。また、この構造では、屈曲部4cや先端部4bが各板部8,9の板表面に所定の傾斜角で当接するため、更に第1板部8に固定する際にアースクリップ7Aを回転するため、各板部8,9の板表面に施されている絶縁性の塗料や被膜に対する剥離作用も良好に得られる。   An important point in this structure is that the bent portion 4c and the tip portion 4b constituting the contact piece 4 are inclined or inclined even if the distance L between the plate portion 8 and the plate portion 9 is changed or narrowed. This can be dealt with only by setting the corners, and can easily be satisfied even when the distance L is as narrow as 1 mm or less (for example, 0.5 to 0.3 mm). Further, in this structure, since the bent portion 4c and the tip portion 4b are in contact with the plate surfaces of the plate portions 8 and 9 at a predetermined inclination angle, the ground clip 7A is rotated when further fixing to the first plate portion 8. For this reason, the peeling action with respect to the insulating paint or coating applied to the plate surfaces of the plate portions 8 and 9 can be obtained well.

なお、本発明は、以上の各形態に制約されるものではなく、請求項で特定される技術要素を備えておればよく、細部についてはこれをベースにして展開可能なものである。その一例としては、クリップの全寸を小さくするため上記当接片をクリップ軸方向ではなく、クリップ軸の周方向に切り起こすようにしてもよい。   Note that the present invention is not limited to the above-described embodiments, and may be provided with the technical elements specified in the claims, and the details can be developed based on this. As an example, in order to reduce the overall size of the clip, the contact piece may be raised not in the clip axis direction but in the circumferential direction of the clip axis.
