各支持部１１は、外壁面１ｂの上端から下端まで縦方向に延びる略四角ブロック状を呈しており、外壁面１ｂから突出した基端部には、係止溝１２が設けられている。係止溝１２は、両支持部１１の向かい合う内側面に、それぞれ支持部１１の上端から下方に向けて所定距離だけ延びた、所定幅の溝から構成されている。係止溝１２の上端は、支持部１１の上面に開口している。   Each support portion 11 has a substantially square block shape extending in the vertical direction from the upper end to the lower end of the outer wall surface 1b, and a locking groove 12 is provided at a base end portion protruding from the outer wall surface 1b. The locking groove 12 is configured by a groove having a predetermined width that extends from the upper end of the support portion 11 downward by a predetermined distance on the inner side surfaces of the support portions 11 facing each other. The upper end of the locking groove 12 is open on the upper surface of the support portion 11.

図３（ａ）は固定金具２を展開した状態、図３（ｂ）は固定金具２を組み立てた状態を示す斜視図である。固定金具２は、例えば、銅やステンレス等の金属から形成されており、ハウジング１の支持部１１に係止して基板Ｋ上に取り付けられる取付片３と、この取付片３の下端から下方に延びる舌片３ｂから構成される挿入係止片４とを備える。   3A is a perspective view showing a state in which the fixing bracket 2 is unfolded, and FIG. 3B is a perspective view showing a state in which the fixing bracket 2 is assembled. The fixing bracket 2 is made of, for example, a metal such as copper or stainless steel, and is attached to the support portion 11 of the housing 1 and attached on the substrate K, and downward from the lower end of the attachment piece 3. And an insertion locking piece 4 composed of an extending tongue piece 3b.

図３（ａ）に示すように、固定金具２は、矩形の平板の上端部に拡幅部、下端部の幅方向中央部に貫通孔３ａをそれぞれ設け、更に下端縁部の幅方向中央部に下方に延びる矩形の舌片３ｂを設けた形状の板状体から形成されている。平板の下端部側には幅方向に沿って折曲用切込部３ｃが設けられている。また、舌片３ｂの根元部分には折曲用切込部３ｄ、長さ方向中央部には折曲用切込部３ｅがそれぞれ設けられている。折曲用切込部３ｄ，３ｅは、舌片３ｂの幅方向に沿ってそれぞれ延びている。固定金具２を構成する板状体は、平板をプレス加工により打ち抜いて形成されており、貫通孔３ａ及び折曲用切込部３ｃ〜３ｅもこの打ち抜き時に形成されている。   As shown in FIG. 3 (a), the fixing bracket 2 is provided with a widened portion at the upper end of a rectangular flat plate and a through hole 3a at the center in the width direction at the lower end, and further at the center in the width direction at the lower end edge. It is formed from a plate-like body having a shape with a rectangular tongue piece 3b extending downward. On the lower end side of the flat plate, a bending cut portion 3c is provided along the width direction. Further, a bending cut portion 3d is provided at the root portion of the tongue piece 3b, and a bending cut portion 3e is provided at the central portion in the length direction. The cutting portions 3d and 3e for bending extend along the width direction of the tongue piece 3b. The plate-like body constituting the fixing bracket 2 is formed by punching a flat plate by press working, and the through hole 3a and the bending notches 3c to 3e are also formed at the time of punching.

固定金具２は、図３（ｂ）に示すように、貫通孔３ａを備える折曲用切込部３ｃよりも下端側を、拡幅部を備える上端側に対して略直角に折り曲げて形成され、折曲部分よりも上側を係止部３１、下側を載置部３２として構成されている。また、載置部３２の下端縁部から下方に延びた舌片３ｂを、延出方向の中央部で折曲用切込部３ｄから上方に向けて略直角に折り曲げ、基端部で折曲用切込部３ｅから更に同じ方向に略直角に折り曲げることにより、舌片３ｂの中央部の折曲用切込部３ｅより先端側を載置部３２の表面側から裏面側に向かって貫通孔３ａに挿通させ、裏面側から突出させて、挿入係止片４が形成されている。   As shown in FIG. 3 (b), the fixture 2 is formed by bending the lower end side of the bending cut portion 3c provided with the through hole 3a substantially at right angles to the upper end side provided with the widened portion, The upper side of the bent portion is configured as a locking portion 31, and the lower side is configured as a placement portion 32. Further, the tongue piece 3b extending downward from the lower edge of the mounting portion 32 is bent at a substantially right angle from the bending cut portion 3d upward at the central portion in the extending direction, and bent at the proximal end portion. By further bending the cut portion 3e in the same direction at a substantially right angle, the front end side of the center portion of the tongue piece 3b is bent from the front surface side of the mounting portion 32 toward the back surface side. An insertion locking piece 4 is formed by being inserted through 3a and protruding from the back side.

係止部３１は、固定金具２をハウジング１の支持部１１に係止して取り付ける取付部である。係止部３１が備える拡幅部の両側への突出部分は、支持部１１が備える係止溝１２に上方から係止する係止片３１ａとなっている。係止片３１ａは、各支持部１１が備える係止溝１２の幅よりもやや薄い厚さを有している。また、係止片３１ａは、係止溝１２の長さよりもやや短い長さだけ、係止部３１の上端から下方に向けて延びている。   The locking portion 31 is an attachment portion that locks and attaches the fixing bracket 2 to the support portion 11 of the housing 1. Projecting portions on both sides of the widened portion provided in the locking portion 31 are locking pieces 31 a that are locked from above into the locking grooves 12 provided in the support portion 11. The locking piece 31a has a thickness that is slightly thinner than the width of the locking groove 12 provided in each support portion 11. The locking piece 31 a extends downward from the upper end of the locking portion 31 by a length slightly shorter than the length of the locking groove 12.

また、係止部３１の高さ方向の中央部には、打出し部３１ｂが設けられている。打出し部３１ｂは、固定金具２の変形を防止するためのものであり、係止部３１を正面から見て長円形状を呈している。   In addition, a launch portion 31 b is provided at the center of the locking portion 31 in the height direction. The launch portion 31b is for preventing deformation of the fixing bracket 2, and has an oval shape when the locking portion 31 is viewed from the front.

載置部３２は、基板Ｋの一主面に載置されて基板Ｋに固定されるためのものである。載置部３２の中央部には、上述した貫通孔３ａが設けられている。載置部３２の一縁部から延びた舌片３ｂから構成される挿入係止片４は、この貫通孔３ａを介して載置部３２の下方に延びている。   The placement unit 32 is placed on one main surface of the substrate K and fixed to the substrate K. The above-described through hole 3 a is provided in the center of the mounting portion 32. The insertion locking piece 4 composed of the tongue piece 3b extending from one edge of the placement portion 32 extends below the placement portion 32 through the through hole 3a.

図２に示すように、ハウジング１の実装される基板Ｋには、挿入係止片４が挿入されて固定される固定孔Ｋ１が設けられている。固定孔Ｋ１は、挿入係止片４の外形よりもやや大きな内形を有した矩形の孔から構成されており、基板Ｋの両主面間を貫通している。また、固定孔Ｋ１の周囲の基板Ｋの主面には、銅箔で覆われた取付部Ｋ１１が設けられている。また、固定孔Ｋ１の内周面にも銅箔で覆われている。   As shown in FIG. 2, the board K on which the housing 1 is mounted is provided with a fixing hole K1 into which the insertion locking piece 4 is inserted and fixed. The fixing hole K <b> 1 is a rectangular hole having an inner shape slightly larger than the outer shape of the insertion locking piece 4, and penetrates between both main surfaces of the substrate K. A mounting portion K11 covered with copper foil is provided on the main surface of the substrate K around the fixing hole K1. Further, the inner peripheral surface of the fixing hole K1 is also covered with copper foil.

次に、このような構成を有する固定金具２を用いて、コネクタのハウジング１を基板Ｋに取り付ける際の動作について説明する。図４（ａ）は固定金具２を用いて基板Ｋに取り付けられたハウジング１の斜視図、図４（ｂ）はそのＡ−Ａ線での断面図である。また、図５は、挿入係止片４と基板Ｋの固定孔Ｋ１との位置関係を説明する図である。   Next, an operation when the housing 1 of the connector is attached to the board K using the fixing bracket 2 having such a configuration will be described. 4A is a perspective view of the housing 1 attached to the substrate K using the fixing bracket 2, and FIG. 4B is a cross-sectional view taken along the line AA. FIG. 5 is a diagram illustrating the positional relationship between the insertion locking piece 4 and the fixing hole K1 of the substrate K.

まず、ハウジング１の支持部１１に固定金具２の取付片３を上方から挿入して係止させ仮止めする。具体的には、載置部３２の設けられた下端側から、ハウジング１の外壁面１ｂが備える両支持部１１間に取付片３を進入させる。   First, the attachment piece 3 of the fixing bracket 2 is inserted into the support portion 11 of the housing 1 from above and locked and temporarily fixed. Specifically, the attachment piece 3 is caused to enter between the support portions 11 provided on the outer wall surface 1 b of the housing 1 from the lower end side where the placement portion 32 is provided.

そして、ハウジング１の上面近くまで移動してきた係止片３１ａの下端を、支持部１１が備える係止溝１２の上端開口部に挿入する。両支持部１１間を取付片３が進入し続けると、係止部３１の係止片３１ａの下端部が、係止溝１２の下端部と当接する。これにより、取付片３の下方への移動が規制されると共に、ハウジング１に対する取付片３の位置決めがなされる。   Then, the lower end of the locking piece 31 a that has moved to the vicinity of the upper surface of the housing 1 is inserted into the upper end opening of the locking groove 12 provided in the support portion 11. When the attachment piece 3 continues to enter between both the support portions 11, the lower end portion of the locking piece 31 a of the locking portion 31 comes into contact with the lower end portion of the locking groove 12. Thereby, the downward movement of the attachment piece 3 is restricted, and the attachment piece 3 is positioned with respect to the housing 1.

このようにして、ハウジング１の左右の外壁面１ｂに、固定金具２の取付片３が係止されて仮止めされる。続いて、図４に示すように、取付片３の仮止めされたハウジング１を、取付片３の載置部３２と共に基板Ｋの取付部Ｋ１１に載置する。この際、図４（ｂ）に示すように、取付片３の載置部３２と一体に構成された挿入係止片４が、基板Ｋが備える固定孔Ｋ１に挿入されるように位置決めを行う。   In this manner, the mounting piece 3 of the fixing bracket 2 is locked and temporarily fixed to the left and right outer wall surfaces 1b of the housing 1. Subsequently, as shown in FIG. 4, the housing 1 to which the attachment piece 3 is temporarily fixed is placed on the attachment portion K <b> 11 of the substrate K together with the placement portion 32 of the attachment piece 3. At this time, as shown in FIG. 4B, positioning is performed so that the insertion locking piece 4 configured integrally with the mounting portion 32 of the mounting piece 3 is inserted into the fixing hole K1 provided in the substrate K. .

挿入係止片４が基板Ｋの固定孔Ｋ１に挿入されたことを確認すると、基板Ｋの取付部Ｋ１１に載置された載置部３２の周囲を取付部Ｋ１１に半田付けする。また、載置部３２の貫通孔３ａの周囲を基板Ｋの取付部Ｋ１１に半田付けする。また、固定孔Ｋ１に挿入された挿入係止片４を固定孔Ｋ１に半田付けする。これらの半田付けに用いられた半田が冷却されて固体化すると、載置部３２及び挿入係止片４が基板Ｋに固定される。挿入係止片４を基板Ｋに固定する半田は、固定手段を構成している。このようにして基板Ｋに固定された挿入係止片４は、載置部３２と一体に構成されており、このため、載置部３２の上方への移動が規制される。   When it is confirmed that the insertion locking piece 4 has been inserted into the fixing hole K1 of the substrate K, the periphery of the placement portion 32 placed on the attachment portion K11 of the substrate K is soldered to the attachment portion K11. Further, the periphery of the through hole 3 a of the mounting portion 32 is soldered to the mounting portion K11 of the substrate K. Further, the insertion locking piece 4 inserted into the fixing hole K1 is soldered to the fixing hole K1. When the solder used for the soldering is cooled and solidified, the mounting portion 32 and the insertion locking piece 4 are fixed to the substrate K. The solder for fixing the insertion locking piece 4 to the substrate K constitutes a fixing means. The insertion locking piece 4 fixed to the substrate K in this way is configured integrally with the placement portion 32, and thus the upward movement of the placement portion 32 is restricted.

上記実施形態の固定金具２によれば、基板Ｋの固定孔Ｋ１に挿入されて固定された挿入係止片４により、載置部３２の上方への移動が規制されるので、単に載置部３２の周縁部を半田付け等の手段を用いて基板Ｋに接続する場合に比べ、載置部３２を基板Ｋから引き離す力が作用した際に、載置部３２が基板Ｋから外れ難くすることができる。この結果、載置部３２と基板Ｋとを引き離す力が基板Ｋの主面に対して垂直方向に働いた場合に、載置部３２と共にコネクタが基板Ｋから外れ難い固定金具２を提供することができる。   According to the fixing bracket 2 of the above embodiment, the upward movement of the mounting portion 32 is restricted by the insertion locking piece 4 inserted and fixed in the fixing hole K1 of the substrate K. Compared to the case where the peripheral portion of 32 is connected to the substrate K by means of soldering or the like, the placement portion 32 is less likely to be detached from the substrate K when a force that separates the placement portion 32 from the substrate K is applied. Can do. As a result, when the force that separates the placement portion 32 and the substrate K acts in a direction perpendicular to the main surface of the substrate K, the fixing bracket 2 is provided with which the connector is difficult to come off from the substrate K together with the placement portion 32. Can do.

また、上記実施形態の固定金具２によれば、挿入係止片４が基板Ｋの固定孔Ｋ１に挿入される位置に載置部３２を位置させることにより、基板Ｋに対する載置部３２の位置決めを行うこともでき、基板Ｋの固定孔Ｋ１及び挿入係止片４を位置決め用の目印としても用いることができる。しかも、挿入係止片４を固定孔Ｋ１に挿入することにより基板Ｋに対してハウジング１を正確に位置決めすることができる。この結果、基板Ｋに対するコネクタの実装作業を簡略化することが可能となる。   Further, according to the fixing bracket 2 of the above embodiment, the mounting portion 32 is positioned with respect to the substrate K by positioning the mounting portion 32 at a position where the insertion locking piece 4 is inserted into the fixing hole K1 of the substrate K. The fixing hole K1 and the insertion locking piece 4 of the substrate K can also be used as positioning marks. Moreover, the housing 1 can be accurately positioned with respect to the substrate K by inserting the insertion locking piece 4 into the fixing hole K1. As a result, it is possible to simplify the mounting operation of the connector on the board K.

また、上記実施形態の固定金具２によれば、挿入係止片４を載置部３２の載置面から下方に突出させるための貫通孔３ａの周辺部を半田付け等の手段を用いて基板Ｋに接続することができる。このため、基板Ｋに対して取付片３をより強固に固定することができる。また、載置部３２に設けられた貫通孔３ａを通して載置部３２の下方に挿入係止片４を突出させていることから、矢印Ａ方向への力が係止部３１に働くと載置部３２の前側部分３２ａに負荷が加えられることにより、また、矢印Ｂ方向への力が係止部３１に働くと載置部３２の後側部分３２ｂに負荷が加えられることにより、挿入係止片４に加えられる負荷が軽減される。このため、挿入係止片４の突出する貫通孔３ａの周囲に負荷を分散することができる。なお、このような作用効果を得るためには、貫通孔３ａの周囲で負荷を十分に分散させられることから、貫通孔３ａが載置部３２の前後方向の中央部に位置していることが好ましい。   Further, according to the fixing metal fitting 2 of the above embodiment, the peripheral portion of the through hole 3a for causing the insertion locking piece 4 to protrude downward from the mounting surface of the mounting portion 32 is used by using means such as soldering. K can be connected. For this reason, the attachment piece 3 can be more firmly fixed to the substrate K. Further, since the insertion locking piece 4 protrudes below the mounting portion 32 through the through hole 3a provided in the mounting portion 32, the mounting is performed when a force in the direction of arrow A acts on the locking portion 31. When a load is applied to the front side portion 32a of the portion 32, and when a force in the direction of arrow B acts on the locking portion 31, a load is applied to the rear side portion 32b of the mounting portion 32. The load applied to the piece 4 is reduced. For this reason, a load can be distributed around the through-hole 3a from which the insertion locking piece 4 protrudes. In order to obtain such an effect, the load can be sufficiently dispersed around the through hole 3a, so that the through hole 3a is located at the center in the front-rear direction of the mounting portion 32. preferable.

上記実施形態の説明では、挿入係止片４が挿入される基板Ｋの被挿通部として、基板Ｋの両主面間を貫通する固定孔Ｋ１を用いた場合について説明した。しかしながら、挿入係止片４を挿入して固定することができるのであれば、被挿通部の構成は任意であり、例えば、基板Ｋの一主面から所定の深さをする穴から被挿通部を構成してもよい。   In the description of the above embodiment, the case where the fixing hole K1 penetrating between both main surfaces of the substrate K is used as the insertion portion of the substrate K into which the insertion locking piece 4 is inserted has been described. However, as long as the insertion locking piece 4 can be inserted and fixed, the configuration of the insertion portion is arbitrary. For example, the insertion portion is inserted through a hole having a predetermined depth from one main surface of the substrate K. May be configured.

また、上記実施形態の説明では、載置部３２に１つの挿入係止片４を設けた場合について説明したが、載置部３２に設ける挿入係止片４の数量は任意である。この場合、載置部３２の縁部に設けられた複数の舌片３ｂから各挿入係止片４を構成しても、また、１つの舌片３ｂの先端側に複数の突片を設けてそれぞれを挿入係止片４としてもよい。   In the description of the above embodiment, the case where one insertion locking piece 4 is provided on the mounting portion 32 has been described. However, the number of the insertion locking pieces 4 provided on the mounting portion 32 is arbitrary. In this case, even if each insertion locking piece 4 is composed of a plurality of tongue pieces 3b provided at the edge of the mounting portion 32, a plurality of protrusion pieces are provided on the tip side of one tongue piece 3b. Each may be an insertion locking piece 4.

また、上記実施形態の説明では、ハウジング１の支持部１１に設けられた係止溝１２に、係止部３１の係止片３１ａを挿入することにより、ハウジング１に取付片３を取り付けて仮止めした場合について説明したが、ハウジング１に対する取付片３の取付方法は任意であり、例えば、ネジ止めや接着剤等の他の手段を用いた取付方法であってもよい。   In the description of the above embodiment, the attachment piece 3 is attached to the housing 1 by temporarily inserting the engagement piece 31 a of the engagement portion 31 into the engagement groove 12 provided in the support portion 11 of the housing 1. Although the case where it stopped | fastened was demonstrated, the attachment method of the attachment piece 3 with respect to the housing 1 is arbitrary, For example, the attachment method using other means, such as screwing and an adhesive agent, may be sufficient.

また、固定金具２に設けられた突起を折り曲げ、基板Ｋに設けられた固定孔Ｋ１に表面から裏面に向かって挿通し、基板に固定されるのであれば、挿入係止片４の構成も任意である。例えば、上記実施形態の説明では、載置部３２の下端縁部から下方に延びる舌片３ｂで挿入係止片４を構成した場合について説明した。しかしながら、載置部３２を切断して形成された舌片を、下方に折り曲げて挿入係止片４を構成してもよい。   Further, if the protrusion provided on the fixing bracket 2 is bent and inserted into the fixing hole K1 provided on the substrate K from the front surface to the back surface and fixed to the substrate, the configuration of the insertion locking piece 4 is also arbitrary. It is. For example, in the description of the above embodiment, the case where the insertion locking piece 4 is configured by the tongue piece 3b extending downward from the lower end edge portion of the placement portion 32 has been described. However, the insertion locking piece 4 may be configured by bending a tongue piece formed by cutting the mounting portion 32 downward.

また、固定手段の種類も任意であり、例えば、ボンドや固定ジグ等、本発明を実施する上で好適なものを用いることができる。これらの手段を用いて載置部３２を基板Ｋに固定する場合でも、基板Ｋの固定孔Ｋ１に挿入されて固定された挿入係止片４が載置部３２と一体に構成されていることから、載置部３２を基板Ｋに強固に固定して、基板Ｋからハウジング１が容易に外れるのを防止することができる。   Moreover, the kind of fixing means is also arbitrary, For example, what is suitable when implementing this invention, such as a bond and a fixing jig, can be used. Even when the mounting portion 32 is fixed to the substrate K using these means, the insertion locking piece 4 inserted and fixed in the fixing hole K1 of the substrate K is configured integrally with the mounting portion 32. Therefore, the mounting portion 32 can be firmly fixed to the substrate K, and the housing 1 can be prevented from being easily detached from the substrate K.

また、ハウジング１の支持部１１に取り付けられた固定金具２が基板Ｋ上に固定されて、ハウジング１が基板Ｋに取り付けられるのであれば、その取付順序も任意であり、例えば、基板Ｋ上に載置した状態のハウジング１に固定金具２を取り付けてもよい。また、上記実施形態の説明では、支持部１１がハウジング１と一体に構成されている場合について説明した。しかしながら、ハウジング１と支持部１１とは別体に構成されていてもよい。また、上記実施形態の説明では、コネクタのハウジング１を基板Ｋに取り付ける固定金具２に本発明を適用した場合について説明した。しかしながら、コネクタ以外のハウジングの固定に用いる固定金具に本発明を適用することもできる。   Further, if the fixing bracket 2 attached to the support portion 11 of the housing 1 is fixed on the substrate K and the housing 1 is attached to the substrate K, the attachment order is arbitrary, for example, on the substrate K. You may attach the fixing metal fitting 2 to the housing 1 of the mounted state. In the description of the above embodiment, the case where the support portion 11 is configured integrally with the housing 1 has been described. However, the housing 1 and the support portion 11 may be configured separately. In the description of the above embodiment, the case where the present invention is applied to the fixing metal fitting 2 for attaching the connector housing 1 to the board K has been described. However, the present invention can also be applied to a fixture used for fixing a housing other than the connector.
