　［本開示の実施形態の説明］
　最初に本開示の実施形態を列記して説明する。
　本開示の基板用コネクタは、
　（１）回路基板に固定されるハウジングと、前記ハウジングに貫通した状態で保持され、前記ハウジングの外部に配されて前記回路基板のスルーホールに貫通される基板接続部を有する端子金具と、前記基板接続部を前記回路基板側へ向けて貫通させることによって位置決めするアライメントプレートとを備え、前記アライメントプレートは、前記基板接続部の先端部を覆う保護位置と、前記基板接続部における前記先端部よりも基端側の部位を前記アライメントプレートに貫通させる退避位置との間で変位するようになっている。 [Explanation of Embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.
The board connector of the present disclosure is
(1) A housing fixed to a circuit board, a terminal fitting having a board connection portion that is held in a state of penetrating the housing and is arranged outside the housing and penetrated through a through hole of the circuit board, and the above. The alignment plate is provided with an alignment plate that is positioned by penetrating the substrate connection portion toward the circuit board side, and the alignment plate is provided from a protective position that covers the tip portion of the substrate connection portion and from the tip portion of the substrate connection portion. Is also displaced from the retracted position where the base end side portion is penetrated through the alignment plate.
　本開示の基板用コネクタによれば、基板用コネクタを回路基板に取り付ける前は、アライメントプレートを保護位置へ変位させ、基板接続部の先端部をアライメントプレートで覆うようにしておく。このとき、基板接続部の先端部がアライメントプレートよりも回路基板側へ突出しないように覆われていれば、異物との干渉に起因する端子金具の損傷を抑制又は防止することが可能である。また、アライメントプレートを退避位置へ変位させれば、基板接続部がアライメントプレートから回路基板側へ大きく突出するので、基板接続部の先端部をスルーホールに挿入することができる。 According to the board connector of the present disclosure, before attaching the board connector to the circuit board, the alignment plate is displaced to the protective position and the tip of the board connection portion is covered with the alignment plate. At this time, if the tip of the substrate connection portion is covered so as not to protrude toward the circuit board side from the alignment plate, it is possible to suppress or prevent damage to the terminal fittings due to interference with foreign matter. Further, if the alignment plate is displaced to the retracted position, the substrate connection portion protrudes greatly from the alignment plate toward the circuit board side, so that the tip end portion of the substrate connection portion can be inserted into the through hole.

According to this configuration, when a foreign matter approaches the tip of the substrate connecting portion, the foreign matter hits the protrusion, so that interference of the foreign matter with the substrate connecting portion can be suppressed or prevented.
　（３）前記端子金具は複数配列されており、前記突部は、前記端子金具の配列方向に延びた形態であることが好ましい。この構成によれば、端子金具の配列方向に延びた突部によってアライメントプレートの曲げ剛性が高められるので、アライメントプレートが保護位置と退避位置との間で変位する際に、アライメントプレートと基板接続部との間でこじりを生じるおそれがない。 (3) A plurality of the terminal fittings are arranged, and it is preferable that the protrusions extend in the arrangement direction of the terminal fittings. According to this configuration, the bending rigidity of the alignment plate is increased by the protrusion extending in the arrangement direction of the terminal fittings, so that when the alignment plate is displaced between the protection position and the retracted position, the alignment plate and the substrate connection portion are formed. There is no risk of twisting with.
　（４）前記基板接続部は半田によって前記回路基板に固着されるようになっており、前記アライメントプレートにおける前記回路基板との対向面からの前記突部の突出寸法は、前記回路基板における前記半田の突出寸法よりも大きい寸法に設定されていることが好ましい。この構成によれば、アライメントプレートが突部を回路基板に接触させるまで接近しても、半田がアライメントプレートに接触することを防止できる。 (4) The board connection portion is fixed to the circuit board by solder, and the protrusion dimension of the protrusion from the surface of the alignment plate facing the circuit board is the solder on the circuit board. It is preferable that the size is set to be larger than the protrusion size of. According to this configuration, it is possible to prevent the solder from coming into contact with the alignment plate even if the alignment plate approaches the protrusion until it comes into contact with the circuit board.
　（５）前記アライメントプレートは、前記回路基板と平行をなして前記基板接続部を貫通させるプレート本体を有しており、前記アライメントプレートには、前記プレート本体から前記回路基板とは反対方向へ起立した摺接部が形成され、前記ハウジングには、前記アライメントプレートを前記保護位置と前記退避位置との間で変位させる際に前記摺接部に摺接することで前記アライメントプレートをガイドするガイド部が設けられていることが好ましい。この構成によれば、摺接部がガイド部に摺接することによりアライメントプレートの傾きが防止されるので、アライメントプレートを保護位置と退避位置との間で円滑に変位させることができる。 (5) The alignment plate has a plate body that is parallel to the circuit board and penetrates the board connection portion, and the alignment plate stands up from the plate body in a direction opposite to the circuit board. A sliding contact portion is formed, and the housing has a guide portion that guides the alignment plate by sliding contact with the sliding contact portion when the alignment plate is displaced between the protection position and the retracted position. It is preferable that it is provided. According to this configuration, the alignment plate is prevented from tilting due to the sliding contact portion sliding contact with the guide portion, so that the alignment plate can be smoothly displaced between the protection position and the retracted position.

Of the space behind the terminal holding portion 13, the space partitioned between the left and right side wall portions 16 functions as a protective space 17. A pair of symmetrical protective position locking portions 18 and a symmetrical pair of retracting position locking portions 19 are formed on the left and right side wall portions 16. The protective position locking portion 18 is arranged at the lower end portion of the side wall portion 16. The protective position locking portion 18 has a form in which the outer surface of the side wall portion 16 is recessed and the side wall portion 16 is penetrated in the left-right direction.

The upper end portion (base end portion) of the board connecting portion 24 is connected to the rear end of the penetrating portion 23. The lower end portion (tip portion) of the board connection portion 24 functions as a connection end portion 25 penetrating through the through hole 51 of the circuit board 50. The terminal fitting 22 is held by the terminal holding portion 13 in a state where the penetrating portion 23 is penetrated through the terminal holding portion 13 in the front-rear direction. The terminal module 26 is configured by integrating the plurality of terminal fittings 22 into the housing 12 (terminal holding portion 13).
　複数の端子金具２２をハウジング１２に取り付けた状態では、貫通部２３同士が互いに平行をなして並列するとともに、基板接続部２４同士が互いに平行をなして並列する。貫通部２３の前端部は、端子保持部１３の前面からフード部１４内に突出している。フード部１４は、複数本の貫通部２３の前端部を一括して包囲する。貫通部２３の後端部と基板接続部２４の全体は、端子保持部１３の後方に露出している。貫通部２３の後端部と基板接続部２４のうち接続端部２５よりも上方の領域は、保護空間１７内に収容されている。基板接続部２４の接続端部２５は、保護空間１７よりも下方に配され、側壁部１６の下端縁よりも下方へ突出している。図５に示すように、接続端部２５は、回路基板５０のスルーホール５１に貫通され、半田５２により導通可能に接続されるようになっている。 In a state where a plurality of terminal fittings 22 are attached to the housing 12, the penetrating portions 23 are parallel to each other and parallel to each other, and the board connection portions 24 are parallel to each other and parallel to each other.

As shown in FIG. 5, the connection end portion 25 is penetrated through the through hole 51 of the circuit board 50 and is electrically connected by the solder 52.
　アライメントプレート３０は、合成樹脂製であり、プレート本体３１と、左右対称な一対の側板部３４と、左右対称な一対の係止アーム３５と、柱状をなす左右一対の摺接部３７とを備えている。プレート本体３１は、板厚方向を上下方向（基板接続部２４の長さ方向と平行な方向）に向けた平板状をなす。プレート本体３１を基板接続部２４の長さ方向と平行に視た底面視形状（平面視形状）は、長辺を左右方向に向けた長方形をなしている。プレート本体３１には、複数の基板接続部２４を個別に貫通させる複数の位置決め孔３２が形成されている。 The alignment plate 30 is made of synthetic resin and includes a plate main body 31, a pair of symmetrical side plate portions 34, a pair of symmetrical locking arms 35, and a pair of left and right sliding contact portions 37 forming a columnar shape. ing. The plate main body 31 has a flat plate shape with the plate thickness direction directed in the vertical direction (direction parallel to the length direction of the substrate connecting portion 24). The bottom view shape (planar view shape) of the plate body 31 viewed parallel to the length direction of the substrate connection portion 24 is a rectangle with the long side oriented in the left-right direction. The plate body 31 is formed with a plurality of positioning holes 32 through which the plurality of substrate connecting portions 24 are individually penetrated.
　アライメントプレート３０には、プレート本体３１の下面３１Ｓ（プレート本体３１における回路基板５０との対向面）から突出する前後一対の突部３３Ｆ，３３Ｒが形成されている。プレート本体３１からの突部３３Ｆ，３３Ｒの突出方向は、基板接続部２４が位置決め孔３２を貫通した状態において、基板接続部２４がプレート本体３１から突出する方向と同じ方向である。前側の突部３３Ｆは、左右方向に延びており、プレート本体３１の前縁部から下方へリブ状に突出した形態である。後側の突部３３Ｒは、左右方向に延びており、プレート本体３１の後縁部から下方へリブ状に突出した形態である。前後両突部３３Ｆ，３３Ｒは、プレート本体３１の長辺方向（複数の端子金具２２の配列方向と平行な方向）にリブ状に延びているので、プレート本体３１が正面視において湾曲するような形態で変形することを抑制している。 The alignment plate 30 is formed with a pair of front and rear protrusions 33F and 33R protruding from the lower surface 31S of the plate body 31 (the surface of the plate body 31 facing the circuit board 50). The protruding directions of the protrusions 33F and 33R from the plate main body 31 are the same as the direction in which the board connecting portion 24 protrudes from the plate main body 31 when the substrate connecting portion 24 penetrates the positioning hole 32. The protrusion 33F on the front side extends in the left-right direction, and has a rib-like shape protruding downward from the front edge of the plate body 31. The protrusion 33R on the rear side extends in the left-right direction, and has a rib-like shape protruding downward from the trailing edge of the plate body 31. Since the front and rear protrusions 33F and 33R extend in a rib shape in the long side direction of the plate body 31 (direction parallel to the arrangement direction of the plurality of terminal fittings 22), the plate body 31 is curved in the front view. It suppresses deformation in the form.
　左右一対の側板部３４は、プレート本体３１の左右両側縁（外周縁のうち短辺側の縁部）から上方へ直角に立ち上がった形態である。左右一対の係止アーム３５は、側板部３４の上縁部のうち前端部に近い位置から、上方へ片持ち状に延出した形態である。係止アーム３５は、側板部３４に連なる下端部を支点として左右方向へ弾性変形し得るようになっている。係止アーム３５の内側面における上端部（延出端部）には、係止突起３６が形成されている。 The pair of left and right side plate portions 34 are in the form of rising at right angles upward from the left and right side edges of the plate body 31 (the edges on the short side of the outer peripheral edge). The pair of left and right locking arms 35 are in a cantilevered shape extending upward from a position close to the front end portion of the upper edge portion of the side plate portion 34. The locking arm 35 can be elastically deformed in the left-right direction with the lower end portion connected to the side plate portion 34 as a fulcrum. A locking projection 36 is formed on the upper end portion (extending end portion) on the inner surface of the locking arm 35.
　左右一対の摺接部３７は、側板部３４の上縁部における後端部から上方へ延出した形態である。柱状延出部の延出方向は、基板接続部２４の長さ方向と平行な方向である。摺接部３７の底面視形状はＬ字形である。摺接部３７は、ガイド部２０に摺接可能となっている。このとき、摺接部３７は、ガイド部２０の後面と外側面とに摺接するようになっている。 The pair of left and right sliding contact portions 37 have a form extending upward from the rear end portion at the upper edge portion of the side plate portion 34. The extending direction of the columnar extending portion is a direction parallel to the length direction of the substrate connecting portion 24. The bottom view shape of the sliding contact portion 37 is L-shaped. The sliding contact portion 37 can be slidably contacted with the guide portion 20. At this time, the sliding contact portion 37 is in sliding contact with the rear surface and the outer surface of the guide portion 20.
　アライメントプレート３０は、位置決め孔３２に基板接続部２４を貫通させた状態で端子モジュール２６（ハウジング１２の側壁部１６）に取り付けられている。取り付けたアライメントプレート３０は、ハウジング１２（側壁部１６）に対し保護位置（図２，４を参照）と、保護位置よりも上方の退避位置（図３，５，６を参照）との間で上下方向へ相対的に平行移動し得るようになっている。アライメントプレート３０が両位置の間を移動する過程では、摺接部３７がガイド部２０に摺接することにより、アライメントプレート３０が、側壁部１６（ハウジング１２）に対して前後方向及び左右方向に位置決めされる。同じく摺接部３７がガイド部２０に摺接することにより、基板接続部２４の長さ方向に対してアライメントプレート３０が前後方向及び左右方向へ傾くことが防止されている。 The alignment plate 30 is attached to the terminal module 26 (the side wall portion 16 of the housing 12) with the substrate connecting portion 24 penetrating the positioning hole 32. The attached alignment plate 30 is placed between the protection position (see FIGS. 2 and 4) and the retracted position (see FIGS. 3, 5 and 6) above the protection position with respect to the housing 12 (side wall portion 16). It can move relatively in parallel in the vertical direction. In the process of moving the alignment plate 30 between the two positions, the sliding contact portion 37 slides into contact with the guide portion 20, so that the alignment plate 30 is positioned in the front-rear direction and the left-right direction with respect to the side wall portion 16 (housing 12). Will be done. Similarly, since the sliding contact portion 37 is in sliding contact with the guide portion 20, the alignment plate 30 is prevented from tilting in the front-rear direction and the left-right direction with respect to the length direction of the substrate connecting portion 24.
　基板用コネクタ１１を回路基板５０に取り付ける前の状態では、係止アーム３５の係止突起３６が保護位置用係止部１８に係止することにより、アライメントプレート３０を保護位置に保持しておく。保護位置用係止部１８は側壁部１６の下端部に配されているので、アライメントプレート３０が保護位置に保持されている状態では、図４に示すように、プレート本体３１は、位置決め孔３２に基板接続部２４の接続端部２５を貫通させる高さに位置する。この状態では、プレート本体３１の下面３１Ｓからの接続端部２５の下向きの突出寸法は、比較的小さく、プレート本体３１の下面３１Ｓからの突部３３Ｆ，３３Ｒの突出寸法とほぼ同じ寸法である。 In the state before the board connector 11 is attached to the circuit board 50, the alignment plate 30 is held in the protected position by locking the locking projection 36 of the locking arm 35 to the protective position locking portion 18. .. Since the protective position locking portion 18 is arranged at the lower end of the side wall portion 16, when the alignment plate 30 is held at the protective position, the plate body 31 has a positioning hole 32 as shown in FIG. It is located at a height at which the connection end portion 25 of the substrate connection portion 24 is penetrated. In this state, the downward protrusion dimension of the connecting end portion 25 from the lower surface 31S of the plate body 31 is relatively small, and is substantially the same as the protrusion dimension of the protrusions 33F and 33R from the lower surface 31S of the plate body 31.
　本実施例では、プレート本体３１の下面３１Ｓからの基板接続部２４の突出寸法は、プレート本体３１の下面３１Ｓからの突部３３Ｆ，３３Ｒの突出寸法よりも僅かに小さい寸法に設定されているが、基板接続部２４の突出寸法は、突部３３Ｆ，３３Ｒの突出寸法と同じでもよく、突部３３Ｆ，３３Ｒの突出寸法より小さくてもよい。基板接続部２４の突出寸法が小さくなっていると、アライメントプレート３０の下方から異物が接続端部２５に接近しても、異物が接続端部２５に干渉し難い。したがって、異物の干渉を原因として基板接続部２４が損傷するおそれはない。 In this embodiment, the protruding dimension of the substrate connecting portion 24 from the lower surface 31S of the plate body 31 is set to be slightly smaller than the protruding dimension of the protrusions 33F and 33R from the lower surface 31S of the plate body 31. The protruding dimension of the substrate connecting portion 24 may be the same as the protruding dimension of the protrusions 33F and 33R, and may be smaller than the protruding dimension of the protrusions 33F and 33R. When the protruding dimension of the substrate connecting portion 24 is small, even if a foreign matter approaches the connecting end portion 25 from below the alignment plate 30, the foreign matter is unlikely to interfere with the connecting end portion 25. Therefore, there is no possibility that the substrate connection portion 24 will be damaged due to the interference of foreign matter.
　ケース４０は、金属製であり、前面に開口部４１を有している（図６を参照）。ケース４０の下面は、ケース４０内をケース４０外へ開放させる開放部４２として開口している。ケース４０内には、基板用コネクタ１１のうち側壁部１６と、端子金具２２のうち端子保持部１３より後方へ露出した部分が収容される。ケース４０の開放部４２の開口縁のうち後端縁部には、下向きに突出する左右一対の嵌合部４３が形成されている。ケース４０に基板用コネクタ１１を取り付ける際には、基板接続部２４と側壁部１６を開口部４１からケース４０内に収容し、フランジ部１５を開口部４１の前面に当接させ、図示しないビス等の締結部材によりフランジ部１５をケース４０に固定する。ケース４０と基板用コネクタ１１を組み付けた状態では、接続端子が、ケース４０の下面の開放部４２から下方へ突出している。 The case 40 is made of metal and has an opening 41 on the front surface (see FIG. 6). The lower surface of the case 40 is opened as an opening portion 42 that opens the inside of the case 40 to the outside of the case 40. The side wall portion 16 of the board connector 11 and the portion of the terminal fitting 22 exposed rearward from the terminal holding portion 13 are housed in the case 40. A pair of left and right fitting portions 43 projecting downward are formed at the rear end edge portion of the opening edge of the open portion 42 of the case 40. When attaching the board connector 11 to the case 40, the board connection portion 24 and the side wall portion 16 are housed in the case 40 through the opening 41, the flange portion 15 is brought into contact with the front surface of the opening 41, and a screw (not shown) is provided. The flange portion 15 is fixed to the case 40 by a fastening member such as. When the case 40 and the board connector 11 are assembled, the connection terminals project downward from the open portion 42 on the lower surface of the case 40.
　ケース４０に基板用コネクタ１１を組み付けた後は、保護位置に保持されているアライメントプレート３０を退避位置へ移動させ、係止アーム３５の係止突起３６を退避位置用係止部１９に係止させることにより、アライメントプレート３０を退避位置に保持する。退避位置用係止部１９は、保護位置用係止部１８より高い位置に配されている。したがって、アライメントプレート３０が退避位置に保持されている状態では、図５に示すように、プレート本体３１は、位置決め孔３２に接続端部２５よりも上方の部位を貫通させる高さに位置する。また、摺接部３７がストッパ２１に当接することにより、アライメントプレート３０は退避位置よりも上方へ移動することを規制される。 After assembling the board connector 11 to the case 40, the alignment plate 30 held in the protective position is moved to the retracted position, and the locking projection 36 of the locking arm 35 is locked to the retracted position locking portion 19. By doing so, the alignment plate 30 is held in the retracted position. The retracted position locking portion 19 is arranged at a position higher than the protected position locking portion 18. Therefore, in the state where the alignment plate 30 is held in the retracted position, as shown in FIG. 5, the plate main body 31 is located at a height at which the positioning hole 32 penetrates the portion above the connection end portion 25. Further, when the sliding contact portion 37 comes into contact with the stopper 21, the alignment plate 30 is restricted from moving above the retracted position.
　アライメントプレート３０を退避位置に保持した状態では、プレート本体３１の下面３１Ｓからの基板接続部２４の下向きの突出寸法は、アライメントプレート３０が保護位置にあるときよりも大きく、接続端部２５の全体がプレート本体３１及び突部３３Ｆ，３３Ｒよりも下方に位置する。これにより、接続端部２５を回路基板５０のスルーホール５１に挿入することが可能となる。この後、ケース４０に回路基板５０を取り付けるとともに、基板接続部２４を回路基板５０に接続する。このとき、ケース４０の嵌合部４３に、回路基板５０の後縁部に形成されている切欠状の位置決め部５３（図６を参照）を嵌合させることにより、回路基板５０をケース４０に対して位置決めする。これにより、基板接続部２４（接続端部２５）がスルーホール５１に支障なく挿入される。 When the alignment plate 30 is held in the retracted position, the downward protrusion dimension of the substrate connecting portion 24 from the lower surface 31S of the plate body 31 is larger than that when the alignment plate 30 is in the protected position, and the entire connecting end portion 25 is formed. Is located below the plate body 31 and the protrusions 33F and 33R. This makes it possible to insert the connection end portion 25 into the through hole 51 of the circuit board 50. After that, the circuit board 50 is attached to the case 40, and the board connection portion 24 is connected to the circuit board 50. At this time, the circuit board 50 is fitted into the case 40 by fitting the notch-shaped positioning portion 53 (see FIG. 6) formed in the trailing edge portion of the circuit board 50 to the fitting portion 43 of the case 40. Positioning against. As a result, the board connection portion 24 (connection end portion 25) is inserted into the through hole 51 without any trouble.
　尚、アライメントプレート３０は、上述のように、ケース４０に回路基板５０を取り付ける前に、保護位置から退避位置へ変位させておいてもよいが、ケース４０に対する回路基板５０の組付けと同時にアライメントプレート３０を退避位置へ移動させてもよい。この場合、まず、アライメントプレート３０が保護位置にある状態で、接続端部２５をスルーホール５１に浅く進入させるとともに、回路基板５０の上面を下から突部３３Ｆ，３３Ｒに当てる。次に、貫通状態のスルーホール５１と基板接続部２４をガイドとして利用し、回路基板５０を上方へ移動させながらアライメントプレート３０を退避位置へ押し上げる。 As described above, the alignment plate 30 may be displaced from the protective position to the retracted position before the circuit board 50 is attached to the case 40, but the alignment plate 30 is aligned at the same time as the circuit board 50 is assembled to the case 40. The plate 30 may be moved to the retracted position. In this case, first, with the alignment plate 30 in the protected position, the connection end portion 25 is shallowly inserted into the through hole 51, and the upper surface of the circuit board 50 is brought into contact with the protrusions 33F and 33R from below. Next, using the through hole 51 in the penetrating state and the board connecting portion 24 as guides, the alignment plate 30 is pushed up to the retracted position while moving the circuit board 50 upward.
　本実施例の基板用コネクタ１１は、回路基板５０に固定されるハウジング１２と、ハウジング１２に貫通した状態で保持された複数の端子金具２２と、アライメントプレート３０とを有する。端子金具２２は、ハウジング１２の外部に配された基板接続部２４を有し、基板接続部２４は、回路基板５０のスルーホール５１に貫通される。アライメントプレート３０は、基板接続部２４を回路基板５０側へ向けて位置決め孔３２に貫通させることにより位置決めする部材である。アライメントプレート３０は、保護位置と退避位置との間で上下方向に変位するようになっている。アライメントプレート３０が保護位置にある状態では、基板接続部２４の先端部（接続端部２５）が位置決め孔３２に挿入されることによって覆われる。アライメントプレート３０が退避位置にある状態では、基板接続部２４における接続端部２５よりも基端側（上方）の部位が、位置決め孔３２に貫通される。 The board connector 11 of this embodiment has a housing 12 fixed to the circuit board 50, a plurality of terminal fittings 22 held in a state of penetrating the housing 12, and an alignment plate 30. The terminal fitting 22 has a board connecting portion 24 arranged outside the housing 12, and the board connecting portion 24 is penetrated through a through hole 51 of the circuit board 50. The alignment plate 30 is a member for positioning by passing the substrate connecting portion 24 toward the circuit board 50 side through the positioning hole 32. The alignment plate 30 is designed to be displaced in the vertical direction between the protection position and the retracted position. When the alignment plate 30 is in the protected position, the tip end portion (connection end portion 25) of the substrate connection portion 24 is covered by being inserted into the positioning hole 32. When the alignment plate 30 is in the retracted position, a portion of the substrate connecting portion 24 on the base end side (above) of the connecting end portion 25 is penetrated through the positioning hole 32.
　基板用コネクタ１１を回路基板５０に取り付ける前は、アライメントプレート３０を保護位置へ変位させ、基板接続部２４の先端部（接続端部２５）が位置決め孔３２に挿入されるようにしておく。この状態では、基板接続部２４の先端部（下端部）が、アライメントプレート３０よりも回路基板５０側（下方）へ殆ど突出せず、基板接続部２４の先端部がアライメントプレート３０によって覆われるので、異物との干渉に起因する端子金具２２（基板接続部２４）の損傷を抑制又は防止することが可能である。また、アライメントプレート３０を退避位置へ変位させれば、基板接続部２４がアライメントプレート３０から回路基板５０側へ大きく突出するので、基板接続部２４の先端部をスルーホール５１に挿入することができる。 Before attaching the board connector 11 to the circuit board 50, the alignment plate 30 is displaced to the protective position so that the tip end portion (connection end portion 25) of the board connection portion 24 is inserted into the positioning hole 32. In this state, the tip end portion (lower end portion) of the substrate connection portion 24 hardly protrudes toward the circuit board 50 side (downward) from the alignment plate 30, and the tip end portion of the substrate connection portion 24 is covered by the alignment plate 30. It is possible to suppress or prevent damage to the terminal fitting 22 (board connection portion 24) due to interference with foreign matter. Further, if the alignment plate 30 is displaced to the retracted position, the substrate connecting portion 24 protrudes greatly from the alignment plate 30 toward the circuit board 50, so that the tip portion of the substrate connecting portion 24 can be inserted into the through hole 51. ..
　また、アライメントプレート３０には、プレート本体３１からの基板接続部２４の突出方向と同じ側へ突出した突部３３Ｆ，３３Ｒが形成されている。この構成によれば、アライメントプレート３０が保護位置にある状態で、基板接続部２４の先端部に向かって異物が接近したときには、異物が突部３３Ｆ，３３Ｒに当たることにより、基板接続部２４に対する異物の干渉を抑制又は防止することができる。 Further, the alignment plate 30 is formed with protrusions 33F and 33R protruding in the same direction as the protrusion direction of the substrate connection portion 24 from the plate main body 31. According to this configuration, when the foreign matter approaches the tip of the substrate connecting portion 24 while the alignment plate 30 is in the protective position, the foreign matter hits the protrusions 33F and 33R, so that the foreign matter hits the substrate connecting portion 24. Interference can be suppressed or prevented.
　また、突部３３Ｆ，３３Ｒは、プレート本体３１の長辺方向（複数の端子金具２２が配列されている方向）に沿ってリブ状に細長く延びた形態である。この構成によれば、複数の端子金具２２の配列方向に沿ってリブ状に延びる突部３３Ｆ，３３Ｒにより、アライメントプレート３０の曲げ剛性が高められるので、アライメントプレート３０が保護位置と退避位置との間で変位する際に、アライメントプレート３０と基板接続部２４との間でこじりを生じるおそれがない。 Further, the protrusions 33F and 33R are ribbed and elongated along the long side direction of the plate body 31 (the direction in which a plurality of terminal fittings 22 are arranged). According to this configuration, the bending rigidity of the alignment plate 30 is increased by the protrusions 33F and 33R extending in a rib shape along the arrangement direction of the plurality of terminal fittings 22, so that the alignment plate 30 has a protective position and a retracted position. There is no risk of twisting between the alignment plate 30 and the substrate connection portion 24 when the displacement is performed between the alignment plates 30.
　また、基板接続部２４は半田５２により回路基板５０に固着されるようになっている。図５に示すように、アライメントプレート３０（プレート本体３１）における回路基板５０との対向面（下面３１Ｓ）からの突部３３Ｆ，３３Ｒの突出寸法は、回路基板５０における半田５２の突出寸法より大きい寸法に設定されている。この構成によれば、アライメントプレート３０が突部３３Ｆ，３３Ｒを回路基板５０に接触させるまで接近しても、半田５２がアライメントプレート３０に接触することを防止できる。 Further, the board connection portion 24 is fixed to the circuit board 50 by the solder 52. As shown in FIG. 5, the protruding dimensions of the protrusions 33F and 33R from the facing surface (lower surface 31S) of the alignment plate 30 (plate body 31) with the circuit board 50 are larger than the protruding dimensions of the solder 52 on the circuit board 50. It is set to the dimension. According to this configuration, even if the alignment plate 30 approaches the protrusions 33F and 33R until they come into contact with the circuit board 50, it is possible to prevent the solder 52 from coming into contact with the alignment plate 30.
　また、アライメントプレート３０は、回路基板５０と平行をなし、基板接続部２４を貫通させるプレート本体３１を有している。アライメントプレート３０には、プレート本体３１から回路基板５０とは反対方向へ起立した摺接部３７が形成されている。ハウジング１２には、アライメントプレート３０を保護位置と退避位置との間で変位させる際に摺接部３７に摺接するガイド部２０が形成されている。摺接部３７とガイド部２０は、基板接続部２４と平行であり、アライメントプレート３０をガイドする機能を発揮する。この構成によれば、ガイド部２０と摺接部３７との摺接によりアライメントプレート３０の傾きが防止されるので、アライメントプレート３０を保護位置と退避位置との間で円滑に変位させることができる。 Further, the alignment plate 30 has a plate body 31 that is parallel to the circuit board 50 and penetrates the board connection portion 24. The alignment plate 30 is formed with a sliding contact portion 37 that stands up from the plate body 31 in the direction opposite to the circuit board 50. The housing 12 is formed with a guide portion 20 that is in sliding contact with the sliding contact portion 37 when the alignment plate 30 is displaced between the protection position and the retracted position. The sliding contact portion 37 and the guide portion 20 are parallel to the substrate connecting portion 24, and exhibit a function of guiding the alignment plate 30. According to this configuration, the alignment plate 30 is prevented from tilting due to the sliding contact between the guide portion 20 and the sliding contact portion 37, so that the alignment plate 30 can be smoothly displaced between the protection position and the retracted position. ..
　本実施例のコネクタ装置１０は、上記基板用コネクタ１１と、ケース４０と、回路基板５０とを備えている。ケース４０はハウジング１２に取り付けられており、ケース４０内には、アライメントプレート３０と基板接続部２４が収容される。ケース４０には、回路基板５０の位置決め部５３と嵌合可能な嵌合部４３が形成されている。この構成によれば、嵌合部４３を位置決め部５３に嵌合することにより、基板用コネクタ１１を回路基板５０に対して位置決めすることができる。これにより、スルーホール５１に基板接続部２４（接続端部２５）を確実に挿入することができる。 The connector device 10 of this embodiment includes the above-mentioned board connector 11, a case 40, and a circuit board 50. The case 40 is attached to the housing 12, and the alignment plate 30 and the substrate connection portion 24 are housed in the case 40. The case 40 is formed with a fitting portion 43 that can be fitted with the positioning portion 53 of the circuit board 50. According to this configuration, the board connector 11 can be positioned with respect to the circuit board 50 by fitting the fitting portion 43 into the positioning portion 53. As a result, the substrate connection portion 24 (connection end portion 25) can be reliably inserted into the through hole 51.
