＜請求項１の発明＞
基板取付部が基板に半田付けにより取り付けられ、かつコネクタハウジングの前端部が基板の前端縁から前方へ突出して配置されるため、半田が硬化する前、基板用コネクタが前のめりに倒れて基板から脱落するおそれがある。しかるに本発明によれば、基板取付部の突部が基板と当接することにより、その当接位置を支点として固定部材に後方へのモーメントが生じるため、固定部材を取り付けたコネクタハウジングにも同様に後方へのモーメントが付与され、基板用コネクタが前のめりに倒れるのが回避される。その結果、基板用コネクタが基板から脱落するのが防止される。また、このような構成であれば、コネクタハウジングの前端部を基板の前端部から前方へ大きく突出させることができるため、基板の表面に占めるコネクタハウジングの実装面積を小さくすることができ、スペース効率に優れる。 <Invention of Claim 1>
The board mounting part is attached to the board by soldering, and the front end of the connector housing protrudes forward from the front edge of the board, so the board connector falls to the front and falls off the board before the solder hardens. There is a risk. However, according to the present invention, when the protrusion of the board mounting portion comes into contact with the board, a rearward moment is generated in the fixing member with the contact position as a fulcrum. A backward moment is applied, and the board connector is prevented from falling forward. As a result, the board connector is prevented from falling off the board. Also, with such a configuration, the front end portion of the connector housing can be projected forward from the front end portion of the board, so the mounting area of the connector housing on the surface of the board can be reduced, and space efficiency Excellent.

そして、コネクタハウジングが基板に対して基板接続部及び突部の両当接位置で支持されているため、コネクタハウジングに後方へのモーメントが付与されると、端子金具が基板に強く押し当てられることとなり、基板に対する端子金具の接続信頼性が高められる。 And since the connector housing is supported at both contact positions of the board connecting portion and the protrusion with respect to the board, the terminal fitting is strongly pressed against the board when a backward moment is applied to the connector housing. Thus, the connection reliability of the terminal fitting to the board is improved.

＜請求項２の発明＞
端子金具がコネクタハウジングの後面から後方へ突出する第１片部と第１片部の突出端から基板側へ突出する第２片部とを有し、第１片部と第２片部とがＬ字をなす場合の長さよりも後方へ長くなる余長構造をとっているため、その余長分、基板用コネクタの重心が後方へシフトすることとなる。したがって、基板用コネクタが前のめりに倒れるのがより確実に防止される。 <Invention of Claim 2 >
The terminal fitting has a first piece projecting rearward from the rear surface of the connector housing, and a second piece projecting from the projecting end of the first piece to the board side, and the first piece and the second piece are Since a surplus length structure that is longer to the rear than the length in the case of the L-shape is employed, the center of gravity of the board connector is shifted rearward by the surplus length.

The opposing surfaces of the front and rear mounting grooves 25 are all open and are connected to the mounting surface 26 without a step. A step 27 is formed in the middle of the mounting groove 25 in the vertical direction, and the groove width on the lower side of the mounting groove 25 with the step 27 as a boundary is narrowed.

続いて固定部材４０について説明すると、固定部材４０は金属製の平板材であって、全体として断面Ｌ字形をなしている。ここでは、コネクタハウジング２０の両側面のそれぞれに対応して幅方向に一対の固定部材４０が設けられている。詳しくは固定部材４０は、図４ないし図６に示すように、コネクタハウジング２０の装着部２４の装着面２６に取り付けられるハウジング取付部４１と、基板９０の表面に取り付けられる基板取付部４２とからなる。ハウジング取付部４１は装着部２４の装着面２６に沿うよう高さ方向に起立して配置され、基板取付部４２は基板９０の表面に沿うよう高さ方向と直交する幅方向に突出して配置されている。そして、基板取付部４２は幅狭で前後方向に延出する帯状の形態とされている。   Next, the fixing member 40 will be described. The fixing member 40 is a metal flat plate and has an L-shaped cross section as a whole. Here, a pair of fixing members 40 are provided in the width direction corresponding to each of both side surfaces of the connector housing 20. Specifically, as shown in FIGS. 4 to 6, the fixing member 40 includes a housing attachment portion 41 attached to the attachment surface 26 of the attachment portion 24 of the connector housing 20 and a substrate attachment portion 42 attached to the surface of the substrate 90.

The housing mounting portion 41 is disposed upright in the height direction so as to be along the mounting surface 26 of the mounting portion 24, and the substrate mounting portion 42 is disposed so as to protrude in the width direction orthogonal to the height direction so as to be along the surface of the substrate 90. ing. The board attaching portion 42 is narrow and has a strip shape extending in the front-rear direction.

図４に示すように、ハウジング取付部４１の上段部４３は下段部４４よりも前後方向に幅広の形態とされている。そして、上段部４３の前後両側縁には、複数の係止片４５、４６、４７が形成されている。各係止片４５、４６、４７のうち、上段部４３の最上端に位置するものは、前後両側に大きく張り出す第１係止片４５とされ、上段部４３の最下端に位置するものは、前後両側に第１係止片４５よりも小さく張り出す第２係止片４６とされている。また、上段部４３のほぼ中央部に位置するものは、第１、第２係止片４５、４６の張り出し方向（前後方向）と直交して外側へ屈曲する第３係止片４７とされている。第１、第２係止片４５、４６の先端部には先鋭な食い込み突起４８がやや上向きに突出して形成されている。固定部材４０の取り付け時には、各係止片４５、４６、４７が取付溝２５内の段差２７に当て受けられ、かつ食い込み突起４８が取付溝２５の内面に食い込み、これによって固定部材４０がコネクタハウジング２０の装着部２４に抜け止め保持されるようになっている。また、ハウジング取付部４１の上段部４３には、第３係止片４７とほぼ同じ高さ位置に、前後方向に延びるリブ４９が叩き出しにより形成されている。ハウジング取付部４１はリブ４９によってその剛性が高められている。   As shown in FIG. 4, the upper step portion 43 of the housing mounting portion 41 is wider than the lower step portion 44 in the front-rear direction. A plurality of locking pieces 45, 46, 47 are formed on both front and rear side edges of the upper stage portion 43. Among the locking pieces 45, 46, 47, the one positioned at the uppermost end of the upper step portion 43 is the first locking piece 45 projecting greatly in the front and rear sides, and the one positioned at the lowermost end of the upper step portion 43 is The second locking piece 46 projects smaller than the first locking piece 45 on both the front and rear sides. Also, what is positioned at substantially the center of the upper step 43 is a third locking piece 47 that bends outward perpendicularly to the extending direction (front-rear direction) of the first and second locking pieces 45, 46. Yes. A sharp biting projection 48 is formed to protrude slightly upward at the tip of the first and second locking pieces 45 and 46. When the fixing member 40 is attached, the locking pieces 45, 46, 47 are received by the step 27 in the attachment groove 25, and the biting protrusion 48 bites into the inner surface of the attachment groove 25, whereby the fixing member 40 is connected to the connector housing. 20 is attached to the mounting portion 24 to prevent it from coming off. Further, a rib 49 extending in the front-rear direction is formed on the upper stage portion 43 of the housing attachment portion 41 at the substantially same height as the third locking piece 47 by knocking out. The rigidity of the housing mounting portion 41 is enhanced by ribs 49.

基板取付部４２の前後方向中央部には、ハウジング取付部４１の下段部４４にも跨ってスリット５１が入れられている。また、図５に示すように、基板取付部４２には、スリット５１を介して分断された前後両側領域のそれぞれに、貫通孔５２が形成されている。固定部材４０の取り付け時には、基板取付部４２の板面が基板９０の表面に対向して配置され、各貫通孔５２内に半田が進入し、これによって基板９０に対する固定部材４０の取り付け強度が高められている。   A slit 51 is provided at the center in the front-rear direction of the substrate mounting portion 42 so as to straddle the lower step portion 44 of the housing mounting portion 41. Further, as shown in FIG. 5, through-holes 52 are formed in the board attachment portion 42 in the front and rear side regions divided by the slit 51. When the fixing member 40 is attached, the plate surface of the substrate attachment portion 42 is disposed opposite to the surface of the substrate 90, and solder enters each through hole 52, thereby increasing the attachment strength of the fixing member 40 to the substrate 90. It has been.

さて、図４に示すように、基板取付部４２の前側領域には、突部５３が下向き（基板９０側）に突出して形成されている。突部５３は、基板取付部４２の前端部を鈍角に屈曲させてなり、その突出端が下側へ向けられている。基板取付部４２は、屈曲位置５４を境とする前側で下向きに真直ぐ延びて突部５３を構成するテーパ部５５と、屈曲位置５４を境とする後側でほぼ水平に真直ぐ延びるストレート部５６とからなる。突部５３の突出端は、基板取付部４２の前端を構成するものであって、その下端角部が、固定部材４０の取り付け時に、基板９０に対し幅方向に沿ってほぼ線接触状態で当接する接触部５７とされている。   Now, as shown in FIG. 4, a protrusion 53 is formed in the front region of the substrate mounting portion 42 so as to protrude downward (toward the substrate 90). The projecting portion 53 is formed by bending the front end portion of the board mounting portion 42 at an obtuse angle, and the projecting end is directed downward. The board attachment portion 42 extends downward straight on the front side with respect to the bending position 54 and forms a protrusion 53, and a straight portion 56 that extends substantially horizontally straight on the rear side with respect to the bending position 54. Consists of. The protruding end of the protruding portion 53 constitutes the front end of the board mounting portion 42, and the lower end corner of the protruding portion 53 is in contact with the board 90 in a substantially line contact state along the width direction when the fixing member 40 is mounted. The contact portion 57 is in contact.

次に、本実施形態に係る基板用コネクタ１０の組み立て方法及び基板９０への実装方法等について説明する。
まず、コネクタハウジング２０の各端子挿入孔２２に端子金具８０を圧入して装着するとともに、コネクタハウジング２０の両装着部２４に固定部材４０を装着する。固定部材４０の装着時には、固定部材４０がハウジング取付部４１の取付溝２５内に上方から差し込まれ、各係止片４５、４６、４７及び各食い込み突起４８の係止作用によって固定部材４０がコネクタハウジング２０の装着部２４に抜け止め保持される。 Next, an assembly method of the board connector 10 according to the present embodiment, a mounting method on the board 90, and the like will be described.
First, the terminal fitting 80 is press-fitted and attached to each terminal insertion hole 22 of the connector housing 20, and the fixing member 40 is attached to both the attachment portions 24 of the connector housing 20. When the fixing member 40 is mounted, the fixing member 40 is inserted into the mounting groove 25 of the housing mounting portion 41 from above, and the fixing member 40 is connected to the connector by the locking action of the locking pieces 45, 46, 47 and the biting protrusions 48. The mounting portion 24 of the housing 20 is held to prevent it from coming off.

続いて、基板９０の表面にコネクタハウジング２０を載せる。すると、コネクタハウジング２０の前端部が基板９０の前端よりも前方へ突出して配置される。このとき、基板取付部４２の突部５３の接触部が基板９０の表面に当接するとともに、各端子金具８０の第３片部８６が基板９０の表面に弾性的に当接し、かつコネクタハウジング２０の下面が基板９０の表面と実質的に非接触状態に保たれる。これにより、基板用コネクタ１０は、基板９０に対し、各端子金具８０の第３片部８６が基板９０に当接する後方当接位置と、両固定部材４０の突部５３の接触部が基板９０に当接する前方当接位置とで、両持ち支持される。さらに、固定部材４０ひいてはコネクタハウジング２０には、突部５３が基板９０と当接する前方当接位置を中心とした後方へのモーメント（回転モーメント）が付与され、それに伴って各端子金具８０の第３片部８６が後方当接位置で基板９０の表面に弾性的に強く押し当てられる。このため、基板用コネクタ１０が前のめりに傾くことなく基板９０にしっかり当接して支持される。   Subsequently, the connector housing 20 is placed on the surface of the substrate 90. Then, the front end portion of the connector housing 20 is disposed so as to protrude forward from the front end of the substrate 90. At this time, the contact portion of the protrusion 53 of the board mounting portion 42 contacts the surface of the substrate 90, the third piece 86 of each terminal fitting 80 elastically contacts the surface of the substrate 90, and the connector housing 20. Is maintained in a substantially non-contact state with the surface of the substrate 90. As a result, the board connector 10 has the back contact position where the third piece 86 of each terminal fitting 80 abuts against the board 90 with respect to the board 90, and the contact part between the protrusions 53 of both fixing members 40. Are supported at both front and back positions. Further, the fixing member 40 and thus the connector housing 20 are given a moment (rotational moment) to the rear centering on the front contact position where the protrusion 53 contacts the substrate 90, and accordingly, the terminal fitting 80 of each terminal fitting 80 is moved. The three piece portions 86 are elastically and strongly pressed against the surface of the substrate 90 at the rear contact position. Therefore, the board connector 10 is supported in contact with the board 90 without tilting forward.

次いで、基板用コネクタ１０は基板９０とともにリフロー炉に通され、各端子金具８０及び両固定部材４０に対してリフロー半田付けがなされる。その後、半田が硬化することにより、図１に示すように、各端子金具８０が導電部に電気的に接続されるとともに、コネクタハウジング２０が固定部材４０を介して基板９０に固定される。さらに、コネクタハウジング２０のフード部２１内に前方から図示しない相手コネクタを嵌合させ、各端子金具８０に対応する相手端子金具を電気的に接続させる。   Next, the board connector 10 is passed through a reflow furnace together with the board 90, and reflow soldering is performed on each terminal fitting 80 and both fixing members 40. Thereafter, as the solder hardens, as shown in FIG. 1, each terminal fitting 80 is electrically connected to the conductive portion, and the connector housing 20 is fixed to the substrate 90 via the fixing member 40. Further, a mating connector (not shown) is fitted into the hood portion 21 of the connector housing 20 from the front, and the mating terminal fittings corresponding to the respective terminal fittings 80 are electrically connected.

以上説明したように、本実施形態によれば、基板取付部４２が基板９０に半田付けにより取り付けられ、かつコネクタハウジング２０の前端部が基板９０の前端縁から前方へ突出して配置されるため、半田が硬化する前、基板用コネクタ１０が前のめりに倒れて基板９０から脱落するおそれがある。しかるに本実施形態によれば、基板取付部４２の突部５３が基板９０と当接する前方当接位置を支点として固定部材４０に後方へのモーメントが生じるため、固定部材４０を取り付けたコネクタハウジング２０にも同様に後方へのモーメントが付与され、基板用コネクタ１０が前のめりに倒れるのが回避される。その結果、基板用コネクタ１０が基板９０から脱落するのが防止される。また、このような構成であれば、コネクタハウジング２０の前端部を基板９０の前端部から前方へ大きく突出させることができるため、基板９０の表面に占めるコネクタハウジング２０の実装面積を小さくすることができ、スペース効率に優れる。   As described above, according to the present embodiment, the board attachment portion 42 is attached to the board 90 by soldering, and the front end portion of the connector housing 20 is disposed so as to protrude forward from the front edge of the board 90. Before the solder is cured, the board connector 10 may fall forward and fall off the board 90. However, according to the present embodiment, a rearward moment is generated in the fixing member 40 with the front contact position where the protrusion 53 of the substrate mounting portion 42 contacts the substrate 90 as a fulcrum, so the connector housing 20 to which the fixing member 40 is attached. Similarly, a backward moment is applied, and the board connector 10 is prevented from falling forward. As a result, the board connector 10 is prevented from falling off the board 90. Further, with such a configuration, the front end portion of the connector housing 20 can be protruded largely forward from the front end portion of the board 90, so that the mounting area of the connector housing 20 on the surface of the board 90 can be reduced. And is space efficient.

また、コネクタハウジング２０が基板９０に対して基板接続部８２及び突部５３の両当接位置で支持されているため、コネクタハウジング２０に後方へのモーメントが付与されると、基板接続部８２が基板９０に強く押し付けられることとなり、基板９０に対する端子金具８０の接続信頼性が高められる。   In addition, since the connector housing 20 is supported with respect to the substrate 90 at both contact positions of the substrate connecting portion 82 and the protrusion 53, when a backward moment is applied to the connector housing 20, the substrate connecting portion 82 is It will be strongly pressed against the substrate 90, and the connection reliability of the terminal fitting 80 to the substrate 90 is improved.

＜実施形態２＞
本発明の実施形態２を図７によって説明する。実施形態２に係る基板用コネクタ１０Ａでは、端子金具８０Ａの形状が実施形態１とは部分的に異なる。その他は実施形態１と同様であり、実施形態１と同様の構成には同一符号を付し、重複する説明は省略する。 <Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. In the board connector 10A according to the second embodiment, the shape of the terminal fitting 80A is partially different from that of the first embodiment. The rest of the configuration is the same as that of the first embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals and redundant description is omitted.

各端子金具８０Ａのうち、長寸の端子金具８０Ａの基板接続部８２Ａは、全体としてほぼＺ字形をなし、ハウジング装着部８３Ａから連続しつつ後方へほぼ水平に突出する第１片部８４Ａと、第１片部８４Ａの後端（突出端）に鋭角に連なりつつ斜め下前方に延びる第２片部８５Ａと、第２片部８５Ａの下端に鋭角に連なりつつ基板９０の表面に沿ってほぼ水平に配置される第３片部８６Ａとからなる。第１、第２片部８４Ａ、８５Ａの全長は、実施形態１の第１、第２片部８４、８５よりも長くされている。つまり、第１、第２片部８４Ａ、８５Ａは、両者が互いに直角に連なることでＬ字形をなす場合よりも後方への長さが長くなる余長構造をとっている。したがって、基板用コネクタ１０Ａの重心は余長構造によって前後方向中央よりも後方へシフトすることになり、突部５３が基板９０と当接することで後方へのモーメントを生じさせる作用と相俟って、基板用コネクタ１０Ａが前のめりに倒れるのがよりいっそう確実に防止される。   Of each of the terminal fittings 80A, the board connecting portion 82A of the long terminal fitting 80A has a substantially Z shape as a whole, and a first piece 84A that protrudes substantially horizontally rearward from the housing mounting portion 83A, The second piece 85A extending obliquely downward and forward while being connected to the rear end (protruding end) of the first piece 84A at an acute angle, and substantially horizontal along the surface of the substrate 90 while being connected to the lower end of the second piece 85A at an acute angle. The third piece portion 86A is disposed on the surface. The overall length of the first and second piece portions 84A and 85A is longer than that of the first and second piece portions 84 and 85 of the first embodiment. That is, the first and second piece portions 84A and 85A have a surplus length structure in which both are connected at right angles to each other so that the rearward length is longer than in the case of forming an L shape. Accordingly, the center of gravity of the board connector 10A is shifted backward from the center in the front-rear direction due to the extra length structure, coupled with the action of causing the protrusion 53 to come into contact with the board 90 to generate a rearward moment. The board connector 10A is more reliably prevented from falling forward.
