Description

本開示は、基板用コネクタに関するものである。 The present disclosure relates to a board connector.

特許文献１には、基板に設置される基板用コネクタが開示されている。この基板用コネクタは、基板の表面に載置される合成樹脂製のハウジングと、幅方向に並列した状態でハウジングに保持される複数の端子金具とを備えている。複数の端子金具は、ハウジングを前後方向に貫通した形態である。ハウジングにおける基板との対向面の四隅には設置面が形成されている。ハウジングは、基板の表面に対し４つの設置面だけを接触させた状態で設置されるようになっている。ハウジングの幅方向両外側面には一対の固定部材が組み付けられている。ハウジングは、固定部材を半田付けすることにより基板に固定されている。複数の端子金具は、半田付けにより基板に対して導通可能に接続されるようになっている。 Patent Document 1 discloses a substrate connector installed on a substrate. This substrate connector includes a housing made of synthetic resin mounted on the surface of the substrate, and a plurality of terminal fittings held in the housing in a state of being arranged in parallel in the width direction. The plurality of terminal fittings have a form of penetrating the housing in the front-rear direction. Installation surfaces are formed at the four corners of the housing facing the substrate. The housing is installed in a state where only four installation surfaces are in contact with the surface of the substrate. A pair of fixing members are assembled on both outer surfaces in the width direction of the housing. The housing is fixed to the substrate by soldering a fixing member. The plurality of terminal fittings are soldered so as to be conductively connected to the substrate.

特開２０１８−１２５２２５号公報JP-A-2018-125225 特開２０１５−０５６２０２号公報Japanese Unexamined Patent Publication No. 2015-056202 特開２０１０−０８０１６３号公報Japanese Unexamined Patent Publication No. 2010-080163

基板の表面の平面度が低い場合やハウジングの寸法公差が大きい場合は、４つの設置面の全てが基板の表面に接触しない状態でハウジングが基板に固定されることがある。この場合、ハウジングが基板側へ押されたときに、基板に対するハウジングの姿勢が変化するおそれがある。基板に対するハウジングの姿勢が傾くと、ハウジングに組み付けられている固定部材と基板との半田付け部分への負荷が増大したり、ハウジングに保持されている端子金具と基板との接続部分への負荷が増大したりすることが懸念される。 When the flatness of the surface of the substrate is low or the dimensional tolerance of the housing is large, the housing may be fixed to the substrate in a state where all four installation surfaces do not contact the surface of the substrate. In this case, when the housing is pushed toward the substrate, the posture of the housing with respect to the substrate may change. When the attitude of the housing with respect to the board is tilted, the load on the soldered part between the fixing member assembled to the housing and the board increases, or the load on the connection part between the terminal fittings held in the housing and the board increases. There is concern that it will increase.

本開示の基板用コネクタは、上記のような事情に基づいて完成されたものであって、基板に対するハウジングの姿勢の傾きを防止することを目的とする。 The board connector of the present disclosure has been completed based on the above circumstances, and an object of the present disclosure is to prevent the posture of the housing from being tilted with respect to the board.

First, the embodiments of the present disclosure will be listed and described.
The board connector of the present disclosure is
(1) A housing that can be installed on the mounting surface of the board and
A plurality of terminal fittings that are held in parallel with the housing in the width direction and can be connected to the board.
A substrate facing surface that constitutes the outer surface of the housing and can face the mounting surface,
A pair of first support portions formed on the facing surfaces for the substrate,
It is provided with one second support portion formed on the facing surface for the substrate.
The pair of first support portions are arranged at intervals in the width direction.
The one second support portion is at a position sandwiched between the pair of first support portions in the width direction and at a position different from the pair of first support portions in a direction intersecting the width direction. Arranged,
The housing can be installed on the substrate with only the pair of first support portions and the one second support portion in contact with the mounting surface.

第１の開示の構成によれば、ハウジングは、一対の第１支持部と１つの第２支持部のみを実装面に当てた状態で基板に設置される。一対の第１支持部は、幅方向に間隔を空けて配されている。１つの第２支持部は、幅方向においては一対の第１支持部に挟まれた位置であり、且つ幅方向と交差する方向においては一対の第１支持部と異なる位置に配されている。したがって、基板に対してハウジングの姿勢が傾くおそれがない。 According to the configuration of the first disclosure, the housing is mounted on the substrate with only a pair of first supports and one second support abutting the mounting surface. The pair of first support portions are arranged at intervals in the width direction. One second support portion is arranged at a position sandwiched between a pair of first support portions in the width direction, and is arranged at a position different from the pair of first support portions in a direction intersecting the width direction. Therefore, there is no possibility that the posture of the housing is tilted with respect to the substrate.

（２）前記ハウジングには、金属製の固定部材が、前記実装面に接近する向きに圧入されており、前記固定部材が前記実装面に固定されることで、前記ハウジングが前記基板からの離脱を規制されるようになっていることが好ましい。この構成によれば、金属製の固定部材を半田付けによって実装面に固着することにより、ハウジングが基板から離脱することを確実に防止できる。また、ハウジングは、基板側へ押されても基板に対して傾くことがないので、ハウジングの傾きに起因してハウジングが固定部材から離脱するおそれはない。 (2) A metal fixing member is press-fitted into the housing in a direction approaching the mounting surface, and when the fixing member is fixed to the mounting surface, the housing is separated from the substrate. It is preferable that it is regulated. According to this configuration, the metal fixing member is fixed to the mounting surface by soldering, so that the housing can be reliably prevented from being separated from the substrate. Further, since the housing does not tilt with respect to the substrate even when pushed toward the substrate, there is no possibility that the housing will be separated from the fixing member due to the inclination of the housing.

（３）（２）において、前記固定部材は、前記基板のスルーホールに挿入可能な脚部を有し、前記脚部が半田付けにより前記基板に固着されるようになっていてもよい。この構成によれば、スルーホールに脚部が挿入されることにより、ハウジングは、基板に対し実装面と平行な方向へ位置ずれすることを規制される。ハウジングが、外力の作用等によって姿勢を傾けながら実装面側へ接近した場合、ハウジングに圧入されている固定部材の脚部も、基板に対して相対変位することが懸念される。しかし、ハウジングは、基板に対して姿勢を傾けることがないので、脚部は、基板に対して相対変位することがなく、基板に対して固着した状態に保持される。 (3) In (2), the fixing member may have a leg portion that can be inserted into a through hole of the substrate, and the leg portion may be fixed to the substrate by soldering. According to this configuration, by inserting the legs into the through holes, the housing is restricted from being displaced in a direction parallel to the mounting surface with respect to the substrate. When the housing approaches the mounting surface side while tilting its posture due to the action of an external force or the like, there is a concern that the legs of the fixing member press-fitted into the housing may also be displaced relative to the substrate. However, since the housing does not tilt its posture with respect to the substrate, the legs are not displaced relative to the substrate and are held in a fixed state with respect to the substrate.

（４）前記ハウジングは、前記実装面と直交する向きに相手側コネクタを嵌合させる嵌合部を有していることが好ましい。この構成によれば、ハウジングの嵌合部に相手側コネクタが嵌合されるときには、相手側コネクタから付与される嵌合力によってハウジングが実装面側へ押される。ハウジングは、一対の第１支持部と１つの第２支持部とによって基板に対する傾きを規制されているので、ハウジングの姿勢の傾きに起因して嵌合動作に支障をきたすことはない。 (4) It is preferable that the housing has a fitting portion for fitting the mating connector in a direction orthogonal to the mounting surface. According to this configuration, when the mating side connector is fitted into the fitting portion of the housing, the housing is pushed toward the mounting surface side by the fitting force applied from the mating side connector. Since the housing is restricted from tilting with respect to the substrate by a pair of first support portions and one second support portion, the tilting of the posture of the housing does not hinder the fitting operation.

[Example 1]
A first embodiment of the substrate connector A of the present disclosure will be described with reference to FIGS. 1 to 5. In the first embodiment, the front-back direction is defined as the front in FIGS. 1, 2, and 4. As for the vertical direction, the directions appearing in FIGS. 1 to 3 to 5 (the state in which the board 40 is horizontal, the mounting surface 41 of the board 40 faces upward, and the board connector A is installed on the mounting surface 41) are directly upward. Defined as downward. Regarding the left-right direction, the directions appearing in FIGS. 1 and 3 are defined as left and right as they are. The left-right direction and the width direction are used interchangeably.

図１〜３に示すように、基板用コネクタＡは、ハウジング１０と、複数の端子金具２５と、左右一対の固定部材３０とを備えて構成されている。ハウジング１０は、合成樹脂製であり、全体として長辺を幅方向に向けた直方形をなす。ハウジング１０は、長辺を幅方向に向けた端子保持部１１と、端子保持部１１の外周縁の全周領域から上方へ角筒状に突出したフード状の嵌合部１２とを有する単一部材である。 As shown in FIGS. 1 to 3, the board connector A includes a housing 10, a plurality of terminal fittings 25, and a pair of left and right fixing members 30. The housing 10 is made of synthetic resin and has a rectangular shape with the long side facing the width direction as a whole. The housing 10 is a single housing 10 having a terminal holding portion 11 having a long side oriented in the width direction and a hood-shaped fitting portion 12 protruding upward from the entire peripheral region of the outer peripheral edge of the terminal holding portion 11 in a square tubular shape. It is a member.

図３〜５に示すように、基板用コネクタＡは、基板４０の実装面４１（表面）に固定して設置されるものである。実装面４１にはプリント回路（図示省略）が設けられている。基板４０には、実装面４１から裏面に貫通した形態の複数のスルーホール４２が形成されている。複数のスルーホール４２は、図３に示すように、幅方向（左右方向）に間隔を空けた２つの領域に配されている。各領域において、複数のスルーホール４２が前後方向に間隔を空けて配されている。各スルーホール４２には、固定部材３０の脚部３２が挿入されるようになっている。 As shown in FIGS. 3 to 5, the board connector A is fixedly installed on the mounting surface 41 (surface) of the board 40. A printed circuit (not shown) is provided on the mounting surface 41. A plurality of through holes 42 are formed on the substrate 40 so as to penetrate from the mounting surface 41 to the back surface. As shown in FIG. 3, the plurality of through holes 42 are arranged in two regions spaced apart from each other in the width direction (left-right direction). In each region, a plurality of through holes 42 are arranged at intervals in the front-rear direction. The legs 32 of the fixing member 30 are inserted into each through hole 42.

図１，５に示すように、複数の端子金具２５は、細長い金属部材に曲げ加工を施したものである。各端子金具２５は、上下方向（実装面４１と直角な方向）に延びるハーネス用接続部２６と、ハーネス用接続部２６の下端部から前方又は後方へ延出した基板用接続部２７とを有する。端子金具２５の側面視形状は、略Ｌ字形をなす。端子金具２５は、ハーネス用接続部２６をハウジング１０の下方から端子保持部１１に貫通させた状態で、ハウジング１０に取り付けられている。ハウジング１０に端子金具２５を取り付けた状態では、ハーネス用接続部２６が嵌合部１２内において上向きに突出した形態で収容される。 As shown in FIGS. 1 and 5, the plurality of terminal fittings 25 are formed by bending an elongated metal member. Each terminal fitting 25 has a harness connecting portion 26 extending in the vertical direction (direction perpendicular to the mounting surface 41) and a substrate connecting portion 27 extending forward or backward from the lower end portion of the harness connecting portion 26. .. The side view shape of the terminal fitting 25 is substantially L-shaped. The terminal fitting 25 is attached to the housing 10 with the harness connecting portion 26 penetrating the terminal holding portion 11 from below the housing 10. When the terminal fitting 25 is attached to the housing 10, the harness connecting portion 26 is housed in the fitting portion 12 in a form of projecting upward.

図２，５に示すように、ハウジング１０に取り付けられた複数の端子金具２５は、前列と後列に分かれて配置されている。前列を構成する複数の端子金具２５は、ハーネス用接続部２６が幅方向に一列に並ぶように配置され、基板用接続部２７を前方へ突出させた状態でハウジング１０に保持されている。後列を構成する複数の端子金具２５は、ハーネス用接続部２６が幅方向に一列に並ぶように配置され、基板用接続部２７を後方へ突出させた状態でハウジング１０に保持されている。 As shown in FIGS. 2 and 5, the plurality of terminal fittings 25 attached to the housing 10 are arranged separately in the front row and the rear row. The plurality of terminal fittings 25 constituting the front row are arranged so that the harness connecting portions 26 are arranged in a row in the width direction, and are held in the housing 10 in a state where the substrate connecting portions 27 are projected forward. The plurality of terminal fittings 25 constituting the rear row are arranged so that the harness connecting portions 26 are arranged in a row in the width direction, and are held in the housing 10 in a state where the substrate connecting portions 27 are projected rearward.

図２，３に示すように、ハウジング１０の外面のうち端子保持部１１の下面は、基板用対向面１３となっている。基板用対向面１３は、基板用コネクタＡ（ハウジング１０）を基板４０に取り付けた状態において、実装面４１に対し平行に対向する面である。基板用対向面１３のうち底面視においてハーネス用接続部２６が貫通される部位には、幅方向に細長いリブ状保持部１４Ｆ，１４Ｒが形成されている。リブ状保持部１４Ｆ，１４Ｒは、基板用対向面１３よりも下方（実装面４１側）へ突出している。前列用のリブ状保持部１４Ｆは、幅方向に間隔を空けて直列状に並ぶように配置されている。後列用のリブ状保持部１４Ｒも、幅方向に間隔を空けて直列状に並ぶように配置されている。 As shown in FIGS. 2 and 3, the lower surface of the terminal holding portion 11 of the outer surface of the housing 10 is a substrate facing surface 13. The board facing surface 13 is a surface that faces parallel to the mounting surface 41 when the board connector A (housing 10) is attached to the board 40. Ribbed holding portions 14F and 14R elongated in the width direction are formed at a portion of the substrate facing surface 13 through which the harness connecting portion 26 is penetrated when viewed from the bottom surface. The rib-shaped holding portions 14F and 14R project downward (on the mounting surface 41 side) from the substrate facing surface 13. The rib-shaped holding portions 14F for the front row are arranged so as to be arranged in series with an interval in the width direction. The rib-shaped holding portions 14R for the rear row are also arranged so as to be arranged in series with an interval in the width direction.

図１〜３に示すように、ハウジング１０は、基板用対向面１３の幅方向両端縁部から下方（実装面４１側）へ突出した形態の一対の側壁部１５を有する。一対の側壁部１５は、基板用対向面１３よりも下方へ突出している。図３に示すように、基板用対向面１３からの側壁部１５の突出寸法は、基板用対向面１３からのリブ状保持部１４Ｆ，１４Ｒの突出寸法より大きい。 As shown in FIGS. 1 to 3, the housing 10 has a pair of side wall portions 15 protruding downward (on the mounting surface 41 side) from both end edges in the width direction of the substrate facing surface 13. The pair of side wall portions 15 project downward from the substrate facing surface 13. As shown in FIG. 3, the protrusion dimension of the side wall portion 15 from the substrate facing surface 13 is larger than the protrusion dimension of the rib-shaped holding portions 14F and 14R from the substrate facing surface 13.

図１，２，４，５に示すように、一対の側壁部１５の後端部には、左右対称な一対の第１支持部１６が形成されている。一対の第１支持部１６は、互いに幅方向に間隔を空けた位置関係であり、ハウジング１０（基板用対向面１３）の幅方向における両端部に配置されている。一対の第１支持部１６は、幅方向において、複数の端子金具２５の配置領域全体を挟む２位置に配置されている。一対の第１支持部１６は、前後方向（幅方向と交差する方向）において、後列の端子金具２５のハーネス用接続部２６（後列用のリブ状保持部１４Ｒ）よりも後方に配置されている。 As shown in FIGS. 1, 2, 4 and 5, a pair of symmetrical first support portions 16 are formed at the rear end portions of the pair of side wall portions 15. The pair of first support portions 16 have a positional relationship spaced apart from each other in the width direction, and are arranged at both ends of the housing 10 (opposite surface 13 for a substrate) in the width direction. The pair of first support portions 16 are arranged at two positions in the width direction so as to sandwich the entire arrangement region of the plurality of terminal fittings 25. The pair of first support portions 16 are arranged behind the harness connection portion 26 (rib-shaped holding portion 14R for the rear row) of the terminal fittings 25 in the rear row in the front-rear direction (direction intersecting the width direction). ..

図４，５に示すように、第１支持部１６は、側壁部１５のうち第１支持部１６よりも前方の領域に対し、下方（実装面４１側）へ段差状に突出した形状である。第１支持部１６の下端面（突出端面）は、平面からなる第１支持面１７となっている。図２に示すように、ハウジング１０を下側（基板４０側）から視た底面視において、第１支持面１７は方形をなしている。図３〜５に示すように、基板用対向面１３を実装面４１と平行に対向させた状態において、第１支持面１７の高さは、リブ状保持部１４Ｆ，１４Ｒの下面よりも低く、基板用接続部２７の下面よりも僅かに低い位置である。 As shown in FIGS. 4 and 5, the first support portion 16 has a shape protruding downward (on the mounting surface 41 side) with respect to the region of the side wall portion 15 in front of the first support portion 16. .. The lower end surface (protruding end surface) of the first support portion 16 is a first support surface 17 formed of a flat surface. As shown in FIG. 2, the first support surface 17 has a square shape when the housing 10 is viewed from below (the substrate 40 side). As shown in FIGS. 3 to 5, the height of the first support surface 17 is lower than the lower surfaces of the rib-shaped holding portions 14F and 14R in a state where the substrate facing surface 13 faces parallel to the mounting surface 41. The position is slightly lower than the lower surface of the substrate connection portion 27.

図１〜３に示すように、ハウジング１０は、基板用対向面１３から下方（実装面４１側）へ突出した形態の第２支持部１８を有する。第２支持部１８の数は１つだけである。第２支持部１８の下端面（突出端面）は、平面からなる第２支持面１９となっている。図２に示すように、ハウジング１０を下側（基板４０側）から視た底面視において、第２支持面１９は方形をなしている。図３〜５に示すように、基板用対向面１３を実装面４１と平行に対向させた状態において、第２支持面１９の高さは、一対の第１支持面１７と同じ高さである。即ち、第２支持面１９の高さは、リブ状保持部１４Ｆ，１４Ｒの下面よりも低く、基板用接続部２７の下面よりも僅かに低い位置である。 As shown in FIGS. 1 to 3, the housing 10 has a second support portion 18 in a form protruding downward (on the mounting surface 41 side) from the substrate facing surface 13. The number of the second support portion 18 is only one. The lower end surface (protruding end surface) of the second support portion 18 is a second support surface 19 formed of a flat surface. As shown in FIG. 2, the second support surface 19 has a square shape when the housing 10 is viewed from below (the substrate 40 side). As shown in FIGS. 3 to 5, the height of the second support surface 19 is the same as that of the pair of first support surfaces 17 when the substrate facing surfaces 13 face each other in parallel with the mounting surface 41. .. That is, the height of the second support surface 19 is lower than the lower surfaces of the rib-shaped holding portions 14F and 14R, and slightly lower than the lower surface of the substrate connecting portion 27.

図２に示すように、第２支持部１８（第２支持面１９）は、幅方向において、２つの前列側のリブ状保持部１４Ｆの間に位置し、一対の第１支持部１６の間に挟まるように配置されている。前後方向において、第２支持部１８の後端部は、前列の端子金具２５のハーネス用接続部２６（前列用のリブ状保持部１４Ｆ）と重なるように位置する。前後方向において、第２支持面１９の全体は、前列の端子金具２５のハーネス用接続部２６（前列用のリブ状保持部１４Ｆ）よりも前方に位置している。 As shown in FIG. 2, the second support portion 18 (second support surface 19) is located between the two rib-shaped holding portions 14F on the front row side in the width direction, and is between the pair of first support portions 16. It is arranged so that it is sandwiched between. In the front-rear direction, the rear end portion of the second support portion 18 is positioned so as to overlap the harness connection portion 26 (rib-shaped holding portion 14F for the front row) of the terminal fitting 25 in the front row. In the front-rear direction, the entire second support surface 19 is located in front of the harness connection portion 26 (rib-shaped holding portion 14F for the front row) of the terminal fitting 25 in the front row.

図１，４，５に示すように、ハウジング１０の幅方向における両外側面には、それぞれ、上下方向に延びる前後一対の溝状圧入部２０が形成されている。対をなす溝状圧入部２０は、前後方向に間隔を空けて配置され、互いに相手側に向かって開口するように対向している。溝状圧入部２０の上端部は、上方へ開放されている。図５に示すように、溝状圧入部２０内には、上方に面するストッパ２１が形成されている。 As shown in FIGS. 1, 4 and 5, a pair of front and rear groove-shaped press-fitting portions 20 extending in the vertical direction are formed on both outer surfaces of the housing 10 in the width direction. The paired groove-shaped press-fitting portions 20 are arranged at intervals in the front-rear direction, and face each other so as to open toward the other side. The upper end of the groove-shaped press-fitting portion 20 is open upward. As shown in FIG. 5, a stopper 21 facing upward is formed in the groove-shaped press-fitting portion 20.

一対の固定部材３０は、金属板材に曲げ加工を施したものである。図４，５に示すように、固定部材３０は、平板状をなす本体部３１と、本体部３１の下端縁から下方へ突出した複数の脚部３２とを有する単一部材である。複数の脚部３２は、前後方向に間隔を空けて配置されている。本体部３１からの脚部３２の突出方向は、ハウジング１０に対する固定部材３０の組み付け方向と同じ方向である。固定部材３０は、ハウジング１０の上方から本体部３１の前後両側縁部を溝状圧入部２０に圧入することにより、ハウジング１０に組み付けられている。ハウジング１０に対する固定部材３０の組付け方向は、基板用コネクタＡを基板４０に設置した状態において、実装面４１に対する基板用対向面１３の対向方向と同じ方向である。 The pair of fixing members 30 are made by bending a metal plate material. As shown in FIGS. 4 and 5, the fixing member 30 is a single member having a main body portion 31 having a flat plate shape and a plurality of leg portions 32 protruding downward from the lower end edge of the main body portion 31. The plurality of legs 32 are arranged at intervals in the front-rear direction. The protruding direction of the legs 32 from the main body 31 is the same as the assembling direction of the fixing member 30 with respect to the housing 10. The fixing member 30 is assembled to the housing 10 by press-fitting the front and rear side edges of the main body 31 into the groove-shaped press-fitting portion 20 from above the housing 10. The assembling direction of the fixing member 30 with respect to the housing 10 is the same direction as the facing direction of the board facing surface 13 with respect to the mounting surface 41 when the board connector A is installed on the board 40.

固定部材３０がハウジング１０に対し正規の位置まで組み付けられると、本体部３１の上端部に形成した前後一対の突起部３３がストッパ２１に当たる。これにより、固定部材３０がハウジング１０に対し上下方向に位置決めされる。固定部材３０がハウジング１０に組み付けられた状態では、複数の脚部３２が一対の側壁部１５の下端面から下方へ突出する。脚部３２は、第１支持部１６よりも前方の領域に配置されている。脚部３２の下端（突出端）は、第１支持面１７、第２支持面１９及び基板用接続部２７よりも下方に位置する。 When the fixing member 30 is assembled to the housing 10 to a proper position, a pair of front and rear protrusions 33 formed on the upper end of the main body 31 hit the stopper 21. As a result, the fixing member 30 is positioned in the vertical direction with respect to the housing 10. When the fixing member 30 is assembled to the housing 10, the plurality of legs 32 project downward from the lower end surfaces of the pair of side wall portions 15. The leg portion 32 is arranged in a region in front of the first support portion 16. The lower end (protruding end) of the leg portion 32 is located below the first support surface 17, the second support surface 19, and the substrate connection portion 27.

基板用コネクタＡを基板４０に取り付ける際には、固定部材３０の脚部３２を基板４０の上方からスルーホール４２に挿入し、一対の第１支持面１７と１つの第２支持面１９を、実装面４１に対し面当たり状態で載置する。このとき、ハウジング１０における基板４０との対向面（基板用対向面１３）のうち実装面４１に接触するのは、一対の第１支持部１６（第１支持面１７）と１つの第２支持部１８（第２支持面１９）だけである。第１支持部１６と第２支持部１８を実装面４１に載置した状態では、基板用接続部２７の下面が実装面４１に対し僅かに間隔を空けている。 When the board connector A is attached to the board 40, the legs 32 of the fixing member 30 are inserted into the through holes 42 from above the board 40, and the pair of first support surfaces 17 and one second support surface 19 are inserted into the through holes 42. It is placed on the mounting surface 41 in a surface contact state. At this time, of the facing surfaces (board facing surfaces 13) of the housing 10 facing the substrate 40, the ones that come into contact with the mounting surface 41 are the pair of first support portions 16 (first support surface 17) and one second support. Only the portion 18 (second support surface 19). When the first support portion 16 and the second support portion 18 are placed on the mounting surface 41, the lower surface of the board connecting portion 27 is slightly spaced from the mounting surface 41.

次に、スルーホール４２に挿入されている脚部３２を、基板４０に対し半田付け３５により固着することにより、固定部材３０を基板４０に固定する。スルーホール４２に脚部３２が挿入されることにより、ハウジング１０は、基板４０に対し実装面４１と平行な方向へ位置ずれすることを規制される。固定部材３０を基板４０に固定する工程と前後又は同時に、基板用接続部２７を、実装面４１のプリント回路に対し半田付け３５により導通可能に接続する。これらの半田付け３５の工程の間、一対の第１支持部１６と１つの第２支持部１８は、実装面４１に面接触させた状態に保たれる。この半田付け３５の工程が終了すると、基板４０に対する基板用コネクタＡの取付けが完了する。 Next, the fixing member 30 is fixed to the substrate 40 by fixing the legs 32 inserted in the through holes 42 to the substrate 40 by soldering 35. By inserting the legs 32 into the through holes 42, the housing 10 is restricted from being displaced with respect to the substrate 40 in a direction parallel to the mounting surface 41. Before and after or at the same time as the step of fixing the fixing member 30 to the substrate 40, the substrate connecting portion 27 is electrically connected to the printed circuit of the mounting surface 41 by soldering 35. During these soldering 35 steps, the pair of first support portions 16 and one second support portion 18 are kept in surface contact with the mounting surface 41. When the soldering 35 process is completed, the attachment of the board connector A to the board 40 is completed.

本実施例１の基板用コネクタＡは、１つのハウジング１０と複数の端子金具２５とを備えている。ハウジング１０は、基板４０の実装面４１に設置可能である。複数の端子金具２５は、それぞれ、基板４０に対して接続可能な基板用接続部２７を有する。複数の端子金具２５は、ハウジング１０に対し幅方向に並列した状態で保持される。複数の基板用接続部２７も幅方向に並ぶ。 The board connector A of the first embodiment includes one housing 10 and a plurality of terminal fittings 25. The housing 10 can be installed on the mounting surface 41 of the substrate 40. Each of the plurality of terminal fittings 25 has a board connecting portion 27 that can be connected to the board 40. The plurality of terminal fittings 25 are held in a state of being parallel to the housing 10 in the width direction. The plurality of board connection portions 27 are also arranged in the width direction.

基板用コネクタＡは、ハウジング１０の外面を構成する基板用対向面１３を有する。即ち、ハウジング１０の外面の一部が基板用対向面１３となっている。基板用対向面１３は、実装面４１と対向可能であり、基板用コネクタＡ（ハウジング１０）を基板４０に取り付けた状態において実装面４１と平行をなす。 The board connector A has a board facing surface 13 that constitutes the outer surface of the housing 10. That is, a part of the outer surface of the housing 10 is a substrate facing surface 13. The board facing surface 13 can face the mounting surface 41 and is parallel to the mounting surface 41 when the board connector A (housing 10) is attached to the board 40.

基板用対向面１３には、一対の第１支持部１６と、１つの第２支持部１８とが形成されている。一対の第１支持部１６は、幅方向に間隔を空けた２位置に配されている。１つの第２支持部１８は、幅方向においては一対の第１支持部１６に挟まれた位置に配されている。１つの第２支持部１８は、幅方向と交差する前後方向においては、一対の第１支持部１６と異なる位置（第１支持部１６よりも前方へずれた位置）に配されている。基板用対向面１３の形成領域内においては、ハウジング１０（基板用対向面１３）のうち一対の第１支持部１６と１つの第２支持部１８のみが最も外面側へ突出した形態である。 A pair of first support portions 16 and one second support portion 18 are formed on the substrate facing surface 13. The pair of first support portions 16 are arranged at two positions spaced apart in the width direction. One second support portion 18 is arranged at a position sandwiched between a pair of first support portions 16 in the width direction. One second support portion 18 is arranged at a position different from that of the pair of first support portions 16 (a position displaced forward from the first support portion 16) in the front-rear direction intersecting the width direction. Within the forming region of the substrate facing surface 13, only a pair of first support portions 16 and one second support portion 18 of the housing 10 (board facing surface 13) project to the outermost surface side.

したがって、ハウジング１０は、一対の第１支持部１６（第１支持面１７）と１つの第２支持部１８（第２支持面１９）のみを実装面４１に当てた状態で基板４０に設置可能となっている。一対の第１支持部１６（第１支持面１７）と１つの第２支持部１８（第２支持面１９）のみを実装面４１に当てた状態では、ハウジング１０に対して基板４０（実装面４１）側へ押す向きの外力が作用しても、ハウジング１０の姿勢が基板４０（実装面４１）に対して傾くおそれがない。したがって、ハウジング１０に組み付けられている固定部材３０と基板４０とが半田付け３５がされている部分への負荷が増大したり、ハウジング１０に保持されている端子金具２５と基板４０との接続部分（半田付け３５がされている部分）への負荷が増大したりすることはない。 Therefore, the housing 10 can be installed on the substrate 40 with only a pair of first support portions 16 (first support surface 17) and one second support portion 18 (second support surface 19) in contact with the mounting surface 41. It has become. When only the pair of first support portions 16 (first support surface 17) and one second support portion 18 (second support surface 19) are in contact with the mounting surface 41, the substrate 40 (mounting surface) is relative to the housing 10. 41) Even if an external force in the direction of pushing toward the side is applied, the posture of the housing 10 is not likely to be tilted with respect to the substrate 40 (mounting surface 41). Therefore, the load on the portion where the fixing member 30 and the substrate 40 assembled to the housing 10 are soldered increases, or the connection portion between the terminal fitting 25 and the substrate 40 held in the housing 10 is increased. The load on (the part where the soldering 35 is performed) does not increase.

ハウジング１０に組み付けた金属製の固定部材３０が、半田付け３５により実装面４１に固定されるようになっている。固定部材３０を半田付け３５によって実装面４１に固着することにより、ハウジング１０が基板４０から離脱することを確実に防止できる。ハウジング１０は、基板４０側へ押されても基板４０に対して傾くことがないので、ハウジング１０の傾きに起因してハウジング１０が固定部材３０から離脱するおそれはない。 The metal fixing member 30 assembled to the housing 10 is fixed to the mounting surface 41 by soldering 35. By fixing the fixing member 30 to the mounting surface 41 by soldering 35, it is possible to reliably prevent the housing 10 from detaching from the substrate 40. Since the housing 10 does not tilt with respect to the substrate 40 even when pushed toward the substrate 40, there is no possibility that the housing 10 will be separated from the fixing member 30 due to the inclination of the housing 10.

本実施例１の基板用コネクタＡは、固定部材３０がハウジング１０に対し圧入により組み付けられている。ハウジング１０に対する固定部材３０の組付け方向（圧入方向）は、実装面４１に接近する向きであり、換言すると、実装面４１に対する基板用対向面１３の対向方向と平行な方向である。そのため、ハウジング１０に対し実装面４１側へ押す方向に外力が作用したときに、ハウジング１０が実装面４１側へ接近するように傾くと、固定部材３０が組み付けられている溝状圧入部２０が変形して、ハウジング１０が固定部材３０に対して相対変位することが懸念される。しかし、ハウジング１０は実装面４１に対して傾くことがないので、ハウジング１０と固定部材３０とが相対変位することはなく、ハウジング１０と固定部材３０の組付け状態が保持される。 In the substrate connector A of the first embodiment, the fixing member 30 is assembled to the housing 10 by press fitting. The assembling direction (press-fitting direction) of the fixing member 30 with respect to the housing 10 is a direction approaching the mounting surface 41, in other words, a direction parallel to the facing direction of the substrate facing surface 13 with respect to the mounting surface 41. Therefore, when an external force acts on the housing 10 in the direction of pushing toward the mounting surface 41, when the housing 10 is tilted so as to approach the mounting surface 41, the groove-shaped press-fitting portion 20 to which the fixing member 30 is assembled becomes There is a concern that the housing 10 may be deformed and displaced relative to the fixing member 30. However, since the housing 10 is not tilted with respect to the mounting surface 41, the housing 10 and the fixing member 30 are not displaced relative to each other, and the assembled state of the housing 10 and the fixing member 30 is maintained.

また、ハウジング１０が、外力を受けること等により、姿勢を傾けながら実装面４１側へ接近した場合、ハウジング１０に圧入されている固定部材３０の脚部３２が、基板４０に対して相対変位することが懸念される。しかし、ハウジング１０は基板４０に対して姿勢を傾けることがないので、脚部３２は基板４０に対して相対変位することがない。したがって、固定部材３０（脚部３２）は基板４０に対して固着した状態に保持される。 Further, when the housing 10 approaches the mounting surface 41 side while tilting its posture due to receiving an external force or the like, the legs 32 of the fixing member 30 press-fitted into the housing 10 are displaced relative to the substrate 40. Is a concern. However, since the housing 10 does not tilt its posture with respect to the substrate 40, the legs 32 do not displace relative to the substrate 40. Therefore, the fixing member 30 (leg portion 32) is held in a state of being fixed to the substrate 40.

ハウジング１０は、実装面４１とは反対側（上方）から実装面４１と直交する向きに相手側コネクタＢ（図４を参照）を嵌合させるための嵌合部１２を有している。ハウジング１０の嵌合部１２に相手側コネクタが嵌合されるときには、相手側コネクタから付与される嵌合力によってハウジング１０が実装面４１側へ押される。ハウジング１０は、一対の第１支持部１６と１つの第２支持部１８とによって基板４０に対する傾きを規制されているので、ハウジング１０の姿勢の傾きに起因して嵌合動作に支障をきたすことはない。 The housing 10 has a fitting portion 12 for fitting the mating side connector B (see FIG. 4) in a direction orthogonal to the mounting surface 41 from the side (upper side) opposite to the mounting surface 41. When the mating connector is fitted to the fitting portion 12 of the housing 10, the housing 10 is pushed toward the mounting surface 41 by the fitting force applied from the mating connector. Since the housing 10 is tilted with respect to the substrate 40 by the pair of the first support portions 16 and the one second support portion 18, the fitting operation is hindered due to the tilt of the posture of the housing 10. There is no.
