Description

接触式コネクタContact connector
　本発明は、位置決めの精度があまり高くない二つの構造体間で、給電線を導通させる接触式のコネクタに関する。特には、駐車中に電気自動車に充電できる立体駐車場を実現すべく、電気自動車を搭載したパレットと、自動車格納室（アドレス）に配置された電源との間で給電するための接触式コネクタに関する。 The present invention relates to a contact-type connector for conducting a power supply line between two structures whose positioning accuracy is not so high. In particular, the present invention relates to a contact-type connector for supplying power between a pallet on which an electric vehicle is mounted and a power source disposed in an automobile storage room (address) in order to realize a three-dimensional parking lot that can be charged to the electric vehicle while parking. .
　電気自動車の蓄電池に充電する方法としては、一般に、家庭用の電源（８～１５Ａ）から充電する普通充電と、充電設備（約１３０Ａ）（ガソリンスタンド等に設置されている）から充電する急速充電の方法がある。急速充電用の装置としては、ガソリンスタンドの給油に使用されるノズルに似た形状のプラグを自動車のレセプタクルに接続するものが提案されている（例えば、特許文献１参照）。普通充電には通常８時間程度が必要であるが、急速充電の場合は３０分程度で済む。 As a method of charging the storage battery of an electric vehicle, in general, normal charging from a household power source (8-15A) and quick charging from a charging facility (about 130A) (installed at a gas station etc.) There is a way. As an apparatus for quick charging, an apparatus has been proposed in which a plug having a shape similar to a nozzle used for refueling a gas station is connected to a receptacle of an automobile (for example, see Patent Document 1). Ordinary charging usually requires about 8 hours, but quick charging requires about 30 minutes.
　一方、電気自動車専用の立体駐車場を設けて、駐車中に充電する方法も提案されている（例えば、特許文献２参照）。このような立体駐車場について図８を参照して説明する。図８に示すように、立体駐車場はエレベータ式の駐車場であり、自動車Ｖが載せられるパレット１００を備える。パレット１００は上下方向かつ左右方向に移動可能であり、その上下移動経路の左右両側に多階に渡って格納室（アドレス）が設けられている。パレット１００には、受電用接点１０１が設けられており、各格納室には、受電用接点１０１に直接あるいは非接触で接続する給電用接点１０３が設けられている。パレット１００が所定の格納室に案内されると、受電用接点１０１と給電用接点１０３とが直接あるいは非接触で通電し、充電が開始される。 On the other hand, a method has been proposed in which a three-dimensional parking lot dedicated to electric vehicles is provided and charged during parking (for example, see Patent Document 2). Such a three-dimensional parking lot will be described with reference to FIG. As shown in FIG. 8, the three-dimensional parking lot is an elevator type parking lot, and includes a pallet 100 on which the automobile V is placed. The pallet 100 is movable in the vertical direction and the horizontal direction, and storage rooms (addresses) are provided over multiple floors on both the left and right sides of the vertical movement path. The pallet 100 is provided with a power receiving contact 101, and each storage chamber is provided with a power feeding contact 103 that is connected to the power receiving contact 101 directly or in a non-contact manner. When the pallet 100 is guided to a predetermined storage chamber, the power receiving contact 101 and the power feeding contact 103 are energized directly or non-contacted to start charging.
　パレット１００の受電用接点１０１と各格納室の給電用接点１０３との直接接続には、プラグとレセプタクルを有する電気コネクタが使用される場合がある。このような立体駐車場はかなり大きい構造物であり、パレット１００の各格納室への位置決め精度は高くない。また、乗せられる車の車種及び重量等によってもパレット１００の位置や高さが変わる場合がある。そこで、プラグとレセプタクルとの間には、プラグとレセプタクルとの装着方向（Ｚ軸方向）及び同方向と直交する方向（Ｘ軸方向及びＹ軸方向）にある程度の許容範囲（２０～３０ｍｍ）（偏芯距離）を有することが必要となる。現在まで、このような条件を満足するコネクタは提案されていない。 An electrical connector having a plug and a receptacle may be used for direct connection between the power receiving contact 101 of the pallet 100 and the power supply contact 103 of each storage chamber. Such a multistory parking lot is a considerably large structure, and the positioning accuracy of each pallet 100 in each storage room is not high. Further, the position and height of the pallet 100 may change depending on the type and weight of the vehicle to be placed. Therefore, between the plug and the receptacle, a certain tolerance (20 to 30 mm) (20 to 30 mm) in the mounting direction of the plug and the receptacle (Z-axis direction) and in the direction orthogonal to the same direction (X-axis direction and Y-axis direction) ( It is necessary to have an eccentric distance). To date, no connector satisfying such conditions has been proposed.

　本発明は上記の問題点に鑑みてなされたものであって、広い給電可能空間を有する接触式コネクタを提供することを目的とする。特には、電気自動車の充電が可能な立体駐車場などのような位置決め精度のあまり高くない構造物間で、給電線を自動的に導通させる接触式のコネクタを提供することを目的とする。 The present invention has been made in view of the above-described problems, and an object thereof is to provide a contact-type connector having a wide power feedable space. In particular, it is an object of the present invention to provide a contact-type connector that automatically conducts a power supply line between structures that do not have a high positioning accuracy such as a multi-level parking lot that can charge an electric vehicle.
　本発明の接触式コネクタは、所望の広がりを有する接触板からなる板状電極と、前記接触板の表面に先端が押し当てられる、軸方向に進退自由に付勢されている棒状電極と、を備え、前記接触板表面の広がりの範囲内、かつ、前記棒状電極の進退範囲内の空間領域において、前記板状電極と前記棒状電極とが接触して両者間で給電が可能である。 The contact-type connector of the present invention comprises: a plate-like electrode comprising a contact plate having a desired spread; and a rod-like electrode that is urged forward and backward in the axial direction, with its tip pressed against the surface of the contact plate. The plate electrode and the rod-shaped electrode are in contact with each other in a space region within the range of the surface of the contact plate and within the range of advancement and retreat of the rod-shaped electrode, and power can be supplied between the two.
本発明によれば、給電可能な空間が、面積が接触板の表面で、高さが棒状電極の進退可能距離である空間領域となり、比較的広い空間内で給電可能となる。このため、位置決めの精度があまり高くない二つの構造体間で給電可能となる。例えば、自動立体駐車場の車載パレットの受電部と自動車格納室（アドレス）の給電部との間などに本コネクタを適用できる。 According to the present invention, the space where power can be supplied is a space region whose area is the surface of the contact plate and whose height is the distance in which the rod-shaped electrode can advance and retreat, and power can be supplied in a relatively wide space. For this reason, it becomes possible to supply power between two structures whose positioning accuracy is not so high. For example, this connector can be applied between a power receiving unit of an in-vehicle pallet of an auto multilevel parking lot and a power supply unit of an automobile storage room (address).
　本発明においては、前記棒状電極を進退可能に案内する、絶縁体からなるガイドブロックを備え、複数の前記ガイドブロックが並列に連結されて、多線コネクタが構成されていることが好ましい。　本発明によれば、コネクタ（プラグ側など）の構成部品であるブロックの形状を標準化できるので、任意の線数のコネクタを迅速・安価に提供することができる。 In the present invention, it is preferable that a guide block made of an insulator that guides the rod-like electrode so as to advance and retreat is provided, and a plurality of the guide blocks are connected in parallel to constitute a multi-wire connector. According to the present invention, the shape of the block, which is a component part of the connector (such as the plug side), can be standardized, so a connector with an arbitrary number of wires can be provided quickly and inexpensively.
　本発明においては、前記ガイドブロックが、前記棒状電極が挿通される貫通孔と、該貫通孔内に配置された、前記棒状電極を前記板状電極方向に付勢するスプリングと、を備えることが好ましい。 In the present invention, the guide block includes a through-hole into which the rod-shaped electrode is inserted, and a spring disposed in the through-hole to urge the rod-shaped electrode in the plate-shaped electrode direction. preferable.
　前記ガイドブロックの具体的な態様として、前記棒状電極の進退方向（Ｚ軸方向）と直交する方向（Ｘ軸方向又はＹ軸方向）における両側面から、それぞれ反対方向に延びる並列連結部を備え、複数の該ガイドブロックを並列したときに、隣接する該ガイドブロックの連結部同士が該並列方向と直交する方向に重ね合わされて連結されることが好ましい。　並列方向とは、左右方向（横方向）と上下方向（縦方向）を含む。 As a specific aspect of the guide block, it is provided with parallel connection portions extending in opposite directions from both side surfaces in a direction (X-axis direction or Y-axis direction) orthogonal to the advance / retreat direction (Z-axis direction) of the rod-shaped electrode, When a plurality of the guide blocks are arranged in parallel, the connecting portions of the adjacent guide blocks are preferably overlapped and connected in a direction orthogonal to the parallel direction. The parallel direction includes a horizontal direction (horizontal direction) and a vertical direction (vertical direction).
　本発明においては、前記板状電極を保持する、絶縁体からなる電極保持ブロックを備え、複数の前記電極保持ブロックが並列に連結されて、多線コネクタが構成されていることが好ましい。　本発明によれば、コネクタ（レセプタクル側など）の構成部品であるブロックの形状を標準化できるので、任意の線数のコネクタを迅速・安価に提供することができる。 In the present invention, it is preferable that an electrode holding block made of an insulator for holding the plate electrode is provided, and a plurality of the electrode holding blocks are connected in parallel to constitute a multi-wire connector. According to the present invention, the shape of the block, which is a component of the connector (receptacle side, etc.) can be standardized, so a connector with an arbitrary number of wires can be provided quickly and inexpensively.
　本発明においては、前記電極保持ブロックが、前記棒状電極の進退方向（Ｚ軸方向）において二つ割りされた前後のブロック片からなり、複数の前記電極保持ブロックを並列したときに、隣接する前記ブロック間において、一方のブロックの前ブロック片ともう一方のブロックの後ブロック片とが前記進退方向において連結されることが好ましい。 In the present invention, the electrode holding block is composed of front and rear block pieces divided in two in the advancing / retreating direction (Z-axis direction) of the rod-shaped electrode, and when a plurality of the electrode holding blocks are arranged in parallel, In the above, it is preferable that the front block piece of one block and the rear block piece of the other block are connected in the forward / backward direction.
　本発明によれば、複数の電極保持ブロックを並列する際に、隣接するブロック間において、一方のブロックの前ブロック片ともう一方のブロックの後ブロック片とを連結するので、前後のブロック片の連結と、隣接するブロックの連結とを同時に行うことができる。つまり、前後のブロック片を連結する機構と、隣接するブロックを連結する機構とを共通とできるので、連結作業をシンプルにできるとともに、部品点数を少なくできる。 According to the present invention, when the plurality of electrode holding blocks are arranged in parallel, the front block piece of one block and the rear block piece of the other block are connected between adjacent blocks. Concatenation and concatenation of adjacent blocks can be performed simultaneously. That is, since the mechanism for connecting the front and rear block pieces and the mechanism for connecting adjacent blocks can be made common, the connecting operation can be simplified and the number of parts can be reduced.
　前記前後のブロック片の具体的な態様として、該前後のブロック片が、前記棒状電極の進退方向（Ｚ軸方向）に直交する面（ＸＹ平面）を拡がる矩形状であり、該前後ブロック片の、前記並列方向（Ｘ軸方向又はＹ軸方向）における両側面の、該前後ブロック片の前面（ＸＹ平面）の中心に対して点対称な位置に、それぞれ連結部が形成されているとともに、前記前ブロック片の各連結部と後ブロック片の各連結部とは、前記前面（ＸＹ平面）において鏡像関係に形成されていることとできる。 As a specific mode of the front and rear block pieces, the front and rear block pieces have a rectangular shape extending in a plane (XY plane) perpendicular to the advancing / retreating direction (Z-axis direction) of the rod-shaped electrode, In addition, connecting portions are respectively formed at positions symmetrical with respect to the center of the front surface (XY plane) of the front and rear block pieces on both side surfaces in the parallel direction (X-axis direction or Y-axis direction), and Each connecting portion of the front block piece and each connecting portion of the rear block piece can be formed in a mirror image relation on the front surface (XY plane).
　本発明によれば、電極保持ブロックを並列したときに、ある電極保持ブロックの前ブロック片の各連結部が、隣接する電極保持ブロックの後ブロック片の各連結部と、進退方向（Ｚ軸方向）に重なる。そこで、重なった連結部同士を固定することにより、前後ブロック片が前後方向（Ｚ軸方向）に連結されるとともに、隣接する電極保持ブロックが並列方向（Ｘ軸方向又はＹ軸方向）に連結される。 According to the present invention, when the electrode holding blocks are arranged in parallel, each connecting portion of the front block piece of a certain electrode holding block is connected to each connecting portion of the rear block piece of the adjacent electrode holding block in the advancing / retreating direction (Z-axis direction). ). Therefore, by fixing the overlapping connecting portions, the front and rear block pieces are connected in the front and rear direction (Z-axis direction), and the adjacent electrode holding blocks are connected in the parallel direction (X-axis direction or Y-axis direction). The
　以上の説明から明らかなように、本発明の接触式コネクタは、板状電極の接触板表面の広がりの範囲内、かつ、棒状電極の進退範囲内の空間領域が給電可能空間となるので、比較的広い空間内で給電可能となる。したがって、位置決めの精度があまり高くない二つの構造体間で自動的に給電可能となり、自動立体駐車場の車載パレットの受電部と自動車格納室（アドレス）の給電部との間などに適用できる。 As is clear from the above description, the contact type connector of the present invention has a space where the contact surface of the plate electrode is spread and the space within the advance / retreat range of the rod electrode is a power supplyable space. Power can be supplied in a wide space. Therefore, it becomes possible to automatically supply power between two structures whose positioning accuracy is not so high, and can be applied between a power receiving unit of an in-vehicle pallet of an auto multilevel parking garage and a power supply unit of an automobile storage room (address).

Further, a recess 20 communicating with the window 19 is formed on the back surface of the front block piece 16. The size of the recess 20 is substantially the same as the size of the front surface 11 a of the contact plate 11. Further, a notch 21 through which the terminal of the power receiving cable is passed is formed on the lower surface of the front block piece 16.
　上下連結部１７、１８は、前ブロック片１６の並列方向（Ｘ軸方向）の両側面に、前ブロック片１６の前面（ＸＹ平面）の中心に対して点対称な位置にそれぞれ形成されている。すなわち、上連結部１７は、前ブロック片１６の一方（この例では－Ｘ軸方向）の側面の上半分から側方に延びるように形成されており、下連結部１８は、もう一方（この例では＋Ｘ軸方向）の側面の下半分から側方に延びるように形成されている。各連結部１７、１８の寸法は等しい。各連結部１７、１８には、前後方向（Ｚ軸方向）に貫通する段付の貫通孔２２が開けられている。この貫通孔２２には、隣接するブロック１５の後ブロック片２６（又は端部アタッチメント４０（詳細後述））を連結するビスが通される。 The upper and lower connecting portions 17 and 18 are formed on both side surfaces in the parallel direction (X-axis direction) of the front block piece 16 at positions that are point-symmetric with respect to the center of the front surface (XY plane) of the front block piece 16. . That is, the upper connecting portion 17 is formed so as to extend laterally from the upper half of the side surface of one of the front block pieces 16 (in the −X axis direction in this example), and the lower connecting portion 18 is the other (this In the example, it is formed so as to extend from the lower half of the side surface in the + X axis direction). The dimension of each connection part 17 and 18 is equal. Each connecting portion 17, 18 is provided with a stepped through hole 22 that penetrates in the front-rear direction (Z-axis direction). A screw that connects the rear block piece 26 (or the end attachment 40 (detailed later)) of the adjacent block 15 is passed through the through hole 22.

　次に、図１Ａ，図１Ｂおよび、図３Ａおよび図３Ｂを参照して棒状電極組立体５０を説明する。　棒状電極組立体５０は、端子ピン５１と、端子ピン５１をＺ軸方向に進退可能に支持するブロック（ガイドブロック）５５とを備える。　端子ピン５１は導電性材料（例えば黄銅）で作製され、図１Ａに示すように、前半部５１ａ及び後半部５１ｂと、両部の間に形成されたフランジ部５２を有する。前半部５１ａの長さは後半部５１ｂの長さの１／３程度である。フランジ部５２は外方向に拡がるように形成されており、その径は前半部５１ａと後半部５１ｂの径よりも大きい。前半部５１ａの先端には、電気接点５３（例えば銀製、金製及びプラチナ製）が形成されている。後半部５１ｂの後端には給電ケーブルＣの端末が接続している。 Next, the rod-shaped electrode assembly 50 will be described with reference to FIGS. 1A, 1B, 3A, and 3B. The rod-shaped electrode assembly 50 includes a terminal pin 51 and a block (guide block) 55 that supports the terminal pin 51 so as to advance and retract in the Z-axis direction. The terminal pin 51 is made of a conductive material (for example, brass), and has a front half 51a and a rear half 51b, and a flange 52 formed between the two, as shown in FIG. 1A. The length of the first half 51a is about 1/3 of the length of the second half 51b. The flange portion 52 is formed so as to expand outward, and its diameter is larger than the diameters of the front half portion 51a and the rear half portion 51b. An electrical contact 53 (for example, made of silver, gold and platinum) is formed at the tip of the front half 51a. The terminal of the power feeding cable C is connected to the rear end of the second half 51b.
　ブロック５５は絶縁性材料（一例でＰＯＭ樹脂）で作製されており、図３Ａに示すようにＺ軸方向に長い直方体状で、両側面にはそれぞれ反対方向に延びる上下の連結部５６、５７が形成されている。ブロック５５は横方向（Ｘ軸方向）に並列して連結可能な構造となっている。 The block 55 is made of an insulating material (for example, POM resin) and has a rectangular parallelepiped shape that is long in the Z-axis direction as shown in FIG. 3A, and upper and lower connecting portions 56 and 57 that extend in opposite directions on both side surfaces. Is formed. The block 55 has a structure that can be connected in parallel in the horizontal direction (X-axis direction).
　ブロック５５のＺ軸方向における中心軸上には、貫通孔５９が開けられている。貫通孔５９の径は、端子ピン５１のフランジ部５２の径とほぼ同じである。貫通孔５９の、板状電極組立体１０に対向する側の端部には、内方向に突き出た段部６１が形成されている。この段部６１における貫通孔５９の径は端子ピン５１の前半部５１ａの径とほぼ同じである。 A through hole 59 is formed on the central axis of the block 55 in the Z-axis direction. The diameter of the through hole 59 is substantially the same as the diameter of the flange portion 52 of the terminal pin 51. A stepped portion 61 protruding inward is formed at the end of the through hole 59 on the side facing the plate electrode assembly 10. The diameter of the through hole 59 in the step portion 61 is substantially the same as the diameter of the front half portion 51 a of the terminal pin 51.
　図３Ａに示すように、上下連結部５６、５７は、ブロック５５の並列方向（Ｘ軸方向）の両側面に、ブロック５５の前面（ＸＹ平面）の中心に対して点対称な位置にそれぞれ形成されている。すなわち、上連結部５６は、ブロック５５の一方（この例では＋Ｘ軸方向）の側面の上半分から側方に延びるように形成されており、下連結部５７は、もう一方（この例では－Ｘ軸方向）の側面の下半分から側方に延びるように形成されている。各連結部５６、５７のＸ軸方向及びＹ軸方向の寸法は等しい。上連結部５６には、縦方向（Ｙ軸方向）に貫通する段付の貫通孔６３が開けられている。この貫通孔６３には、隣接するブロック５５（あるいは端部アタッチメントＡ（詳細後述））を連結するビスが通される。下連結部５７には、縦方向（Ｙ軸方向）に貫通するネジ孔６４が開けられている。このネジ孔６４には、前述のビスが螺合する。 As shown in FIG. 3A, the upper and lower connecting portions 56 and 57 are formed on both side surfaces of the block 55 in the parallel direction (X-axis direction) at positions symmetrical with respect to the center of the front surface (XY plane) of the block 55. Has been. That is, the upper connecting portion 56 is formed so as to extend laterally from the upper half of one side of the block 55 (in this example, + X axis direction), and the lower connecting portion 57 is the other (in this example, − It is formed to extend laterally from the lower half of the side surface in the (X-axis direction) side. The dimensions of the connecting portions 56 and 57 in the X-axis direction and the Y-axis direction are equal. The upper connecting portion 56 has a stepped through hole 63 that penetrates in the vertical direction (Y-axis direction). A screw that connects the adjacent block 55 (or end attachment A (detailed later)) is passed through the through-hole 63. The lower connecting portion 57 is provided with a screw hole 64 penetrating in the vertical direction (Y-axis direction). The aforementioned screw is screwed into the screw hole 64.
　ブロック５５の、板状電極組立体１０と反対側の端部にはカバープレート６５が取り付けられている。カバープレート６５は絶縁性材料（一例でＰＯＭ樹脂）で作製されており、ブロック５５の端面形状と同じ形状である。カバープレート６５には、ブロック５５の貫通孔５９と同軸上に貫通孔６６が開けられている。この貫通孔６６の径は、端子ピン５１の後半部５１ｂの径とほぼ等しい。 A cover plate 65 is attached to an end of the block 55 opposite to the plate electrode assembly 10. The cover plate 65 is made of an insulating material (for example, POM resin) and has the same shape as the end face shape of the block 55. A through hole 66 is formed in the cover plate 65 coaxially with the through hole 59 of the block 55. The diameter of the through hole 66 is substantially equal to the diameter of the rear half portion 51 b of the terminal pin 51.
　図１Ａおよび図１Ｂに示すように、端子ピン５１はブロック５５の貫通孔５９に挿入されて、フランジ部５２が段部６１に当接し、前半部５１ａが貫通孔５９から突き出している。端子ピン５１の後半部５１ｂにはスプリング６７が外嵌されている。スプリング６７は、フランジ部５２とカバープレート６５との間に配置されて、フランジ部５２を前方に付勢している。これにより、端子ピン５１は、前半部５１ａがブロック５５から前方に突き出す姿勢に維持されている。突き出た部分の長さが、端子ピン５１のＺ軸方向の許容範囲となる。この距離は一例で３６ｍｍである。 As shown in FIGS. 1A and 1B, the terminal pin 51 is inserted into the through hole 59 of the block 55, the flange portion 52 abuts on the step portion 61, and the front half portion 51a protrudes from the through hole 59. A spring 67 is fitted on the rear half 51 b of the terminal pin 51. The spring 67 is disposed between the flange portion 52 and the cover plate 65 and urges the flange portion 52 forward. Thereby, the terminal pin 51 is maintained in a posture in which the front half 51a protrudes forward from the block 55. The length of the protruding portion is an allowable range of the terminal pin 51 in the Z-axis direction. This distance is 36 mm as an example.
　端子ピン５１の先端の電気接点５３が板状電極組立体１０の接触板１１に接触すると、両電極間が導通し、コネクタ１を介して給電ケーブルと受電ケーブルが導通する。棒状電極組立体５０と板状電極組立体１０との間隔が所定の間隔よりも短くなった場合は、図１Ｂに示すように、棒状電極組立体５０の端子ピン５１が板状電極組立体１０に押されて相対的に後退する。しかし、端子ピン５１はスプリング６７により前方に付勢されているので、端子ピン５１の先端の接点５３は常に板状電極組立体１０の接触板１１に押し付けられており、両電極間の導電は維持される。 When the electrical contact 53 at the tip of the terminal pin 51 comes into contact with the contact plate 11 of the plate electrode assembly 10, the electrodes are electrically connected, and the power feeding cable and the power receiving cable are electrically connected via the connector 1. When the interval between the rod-shaped electrode assembly 50 and the plate-shaped electrode assembly 10 is shorter than a predetermined interval, the terminal pins 51 of the rod-shaped electrode assembly 50 are connected to the plate-shaped electrode assembly 10 as shown in FIG. 1B. Is pushed backwards relatively. However, since the terminal pin 51 is urged forward by the spring 67, the contact 53 at the tip of the terminal pin 51 is always pressed against the contact plate 11 of the plate electrode assembly 10, and the conduction between the two electrodes is not caused. Maintained.
　棒状電極組立体５０の端子ピン５１の先端の金属接点５３は、板状電極組立体１０のブロック１５の窓１９から露出した接触板１１の前面１１ａ内のどの位置に接触しても両電極間の導通が得られる。　したがって、この例では導通空間の許容範囲は、Ｚ軸方向に３６ｍｍ、Ｘ軸方向に３５ｍｍ、Ｙ軸方向に２５ｍｍである。 The metal contact 53 at the tip of the terminal pin 51 of the rod-shaped electrode assembly 50 is in contact with both electrodes regardless of the position in the front surface 11a of the contact plate 11 exposed from the window 19 of the block 15 of the plate-shaped electrode assembly 10. Continuity is obtained. Therefore, in this example, the allowable range of the conduction space is 36 mm in the Z-axis direction, 35 mm in the X-axis direction, and 25 mm in the Y-axis direction.
　図３Ａおよび図３Ｂに示すように、ブロック５５は、端部アタッチメントＡ７０、Ｂ８０とによって取り付け部に取り付けられる。　端部アタッチメントＡ７０、Ｂ８０は、ブロック５５を取り付け部に取り付けるとともに、隣接するブロック同士を連結するためのものである（連結方法については後述する）。アタッチメントは、ブロック５５の並列方向（Ｘ軸方向）における一方（この例では＋Ｘ軸方向）の側面に配置される端部アタッチメントＡ７０と、もう一方（この例では－Ｘ軸方向）の側面に配置される端部アタッチメントＢ７０とを有する。 As shown in FIG. 3A and FIG. 3B, the block 55 is attached to the attachment portion by the end attachments A70 and B80. The end attachments A70 and B80 are for attaching the block 55 to the attachment portion and for connecting adjacent blocks (the connection method will be described later). The attachments are arranged on the side surface of one end (in this example + X axis direction) of the block 55 in the parallel direction (X axis direction) and on the other side surface (in this example -X axis direction). End attachment B70.
　図３Ａに示すように、端部アタッチメントＡ７０は、正面形状がＬ字型の形状で、ブロック５５を取り付け部に取り付けるための固定部７１と、ブロック５５の上連結部５６が固定される下連結部７２と、を有する。固定部７１は、ブロック５５の厚さ（Ｙ軸方向高さ）と同じ高さであり、縦方向（Ｙ軸方向）に延びる段付の貫通孔７３が開けられている。この貫通孔７３には、ブロック５５を取り付け部に取り付けるためのビスが貫通する。下連結部７２は、固定部７１の半分の厚さであり、固定部７１の側面（－Ｘ軸方向）の下半分から側方（－Ｘ軸方向）に延びている。下連結部７２には、縦方向（Ｙ軸方向）に貫通するネジ孔７４が開けられている。このネジ孔７４には、ブロック５５を取り付けるためのビスが螺合する。 As shown in FIG. 3A, the end attachment A70 has an L-shaped front shape, and a fixed portion 71 for attaching the block 55 to the attachment portion, and a lower connection to which the upper connection portion 56 of the block 55 is fixed.

The lower connecting portion 72 has a screw hole 74 penetrating in the vertical direction (Y-axis direction). A screw for attaching the block 55 is screwed into the screw hole 74.
　端部アタッチメントＢ８０も正面形状がＬ字型の形状で、ブロック５５を取り付け部に取り付けるための固定部８１と、ブロック５５の下連結部５７が連結される上連結部８２と、を有する。固定部８１は、ブロック５５の厚さ（Ｙ軸方向高さ）と同じ高さであり、縦方向（Ｙ軸方向）に貫通する段付の貫通孔８３が開けられている。この貫通孔８３には、ブロック５５を取り付け部に取り付けるためのビスが貫通する。上連結部８２は、固定部の半分の厚さであり、固定部８１の側面（＋Ｘ軸方向）の上半分から側方（＋Ｘ軸方向）に延びている。上連結部８２には、縦方向（Ｙ軸方向）に貫通する段付の貫通孔８４が開けられている。この貫通孔８４には、ブロック５５が取り付けられるためのビスが貫通する。 The end attachment B80 also has an L-shaped front surface, and includes a fixing portion 81 for attaching the block 55 to the attachment portion, and an upper connection portion 82 to which the lower connection portion 57 of the block 55 is connected. The fixing portion 81 has the same height as the thickness of the block 55 (the height in the Y-axis direction), and a stepped through hole 83 that penetrates in the vertical direction (the Y-axis direction) is opened. A screw for attaching the block 55 to the attachment portion passes through the through hole 83.

The upper connecting portion 82 has a stepped through hole 84 that penetrates in the vertical direction (Y-axis direction). A screw for attaching the block 55 passes through the through hole 84.
　図３Ｂを参照して、ブロック５５を各アタッチメント７０、８０に取り付けた状態を説明する。　ブロック５５の一方の側面（＋Ｘ軸方向の側面）に端部アタッチメントＡ７０を噛み合わせると、ブロック５５の上連結部５６が端部アタッチメントＡ７０の下連結部７２と上下方向（Ｙ軸方向）に重なり、上連結部５６の貫通孔６３と下連結部７２のネジ孔７４が同軸上に並ぶ。また、ブロック５５のもう一方の側面（－Ｘ軸方向の側面）に端部アタッチメントＢ８０を噛み合わせると、ブロック５５の下連結部５７が端部アタッチメントＢ８０の上連結部８２と上下方向（Ｙ軸方向）に重なり、上連結部８２の貫通孔８４と下連結部５７のネジ孔６４とが同軸上に並ぶ。そして、貫通孔６３、８４からビスを挿入してネジ孔７４、６４に螺合させることにより、ブロック５５が各アタッチメント７０、８０に固定される。さらに、各アタッチメント７０、８０の固定部７１、８１の貫通孔７３、８３にビスを通して、両アタッチメント７０、８０を取り付け部に固定する。 Referring to FIG. 3B, a state in which the block 55 is attached to each attachment 70, 80 will be described.

　次に、図８で説明した電気自動車専用の立体駐車場のコネクタに、この接触式コネクタを適用する例を、図４～図７を参照して説明する。　図８のような電気自動車用の立体駐車場においては、給電用の電源には一般に単相二線式又は単相三線式の電源が使用される場合がある。本例では単相三線式の場合を示す。立体駐車場用コネクタ９０は、３個の接触式コネクタ１を並列したものとなる。つまり、図４に示すように、立体駐車場用コネクタ９０の受電部９１は、板状電極組立体１０を支持するブロック１５を３個並列して構成され、給電部９３は、棒状電極組立体５０を支持するブロック５５を３個並列して構成される。 Next, an example in which this contact-type connector is applied to the connector of the multilevel parking garage dedicated to the electric vehicle described in FIG. 8 will be described with reference to FIGS. In a multi-story parking lot for an electric vehicle as shown in FIG. 8, a single-phase two-wire type or a single-phase three-wire type power source is generally used as a power source for power supply.
