Description

本発明は、配線基板用コネクタに関する。   The present invention relates to a wiring board connector.

従来の配線基板用コネクタとしては、一方の配線基板にポスト受け用のコネクタを複数設け、他方の配線基板にポストを持つコネクタを複数設け、ポストをポスト受けに嵌合して両コネクタを接続することにより、両配線基板を電気的機械的に接合したものが知られている。   As a conventional wiring board connector, a plurality of post receiving connectors are provided on one wiring board, a plurality of connectors having posts are provided on the other wiring board, and both connectors are connected by fitting the posts to the post receiving. Thus, there is known one in which both wiring boards are joined electrically and mechanically.

上述した従来例では、両コネクタの取付位置が正確ではなく、誤差があると、ポストの位置とポストを挿入する孔の位置が合わず、両コネクタの接続が困難となり、基板同士を電気的機械的に接合することができないという不都合が生じていた。   In the above-mentioned conventional example, if the mounting positions of both connectors are not accurate and there is an error, the positions of the posts and the positions of the holes for inserting the posts do not match, making it difficult to connect the two connectors. Inconvenience that it was not possible to join them.

複数のコネクタ同士の寸法誤差を吸収するとともに、用いるコネクタ自体の背が高くなって実装上問題を生じさせることのないように背が高くならないように工夫したものが開発された。例えば、図７ないし図９に示すように、ポスト１４…を挿入する挿入孔１０…を横２列に複数個穿設したハウジング１１を両側方向に移動自在に収納した枠状の外殻体１２と、ハウジング１１の浮き防止と外殻体１２のプリント基板への固定のための金具１３とを備え、ハウジング１１の各挿入孔１０は独立した角孔であって夫々の挿入孔１０にはコンタクト１５の接触ばね片１５ａをハウジング１１の下面側から上方向に向けて挿入してあり、挿入孔１０の上面開口よりポスト１４が挿入されたときに接触ばね片１５ａが、それに並行する内壁面方向にポスト１４を弾接して電気的に接続するようになっているものが知られている。前記コンタクト１５は、金属ばね材を折り曲げ形成されたもので、接触ばね片１５ａの下端の両側に設けた突起１５ｅを挿入孔１０の内壁に圧接することにより接触ばね片１５ａを挿入孔１０に圧入固定し、更に接触ばね片１５ａの下端より外側方へ延長した延長片を更にハウジング１１の外側壁面に並行するように逆Ｕ字状に折り曲げて、逆Ｕ字状ばね片１５ｂを形成し、この逆Ｕ字状ばね片１５ｂの外側辺の下端部を、外殻体１２の両側内側壁下部に各コンタクト１５に対応して設けた溝１６に圧入固定している。この際、逆Ｕ字状ばね片１５ｂの外側辺の下端部両側に突設した突起１５ｃが溝１６の両側内壁面に圧接することになる。   A device has been developed that absorbs dimensional errors between a plurality of connectors and prevents the connectors used from becoming tall so that they do not become tall and cause problems in mounting. For example, as shown in FIGS. 7 to 9, a frame-shaped outer shell 12 in which a plurality of housings 11 in which a plurality of insertion holes 10 for inserting posts 14 are formed in two horizontal rows is accommodated so as to be movable in both directions. And a metal fitting 13 for preventing the housing 11 from floating and fixing the outer shell body 12 to the printed circuit board. Each insertion hole 10 of the housing 11 is an independent square hole and contacts each insertion hole 10. 15 contact spring pieces 15a are inserted upward from the lower surface side of the housing 11, and when the post 14 is inserted from the upper surface opening of the insertion hole 10, the contact spring pieces 15a are parallel to the inner wall surface direction. It is known that the post 14 is elastically connected to the post 14 for electrical connection. The contact 15 is formed by bending a metal spring material, and the contact spring piece 15a is press-fitted into the insertion hole 10 by pressing the protrusions 15e provided on both sides of the lower end of the contact spring piece 15a against the inner wall of the insertion hole 10. Further, the extension piece extended outward from the lower end of the contact spring piece 15a is further bent in an inverted U shape so as to be parallel to the outer wall surface of the housing 11, thereby forming an inverted U-shaped spring piece 15b. The lower end portion of the outer side of the inverted U-shaped spring piece 15b is press-fitted and fixed in a groove 16 provided in correspondence with each contact 15 at the lower part of the inner side walls of the outer shell 12. At this time, the protrusions 15 c projecting on both sides of the lower end portion of the outer side of the inverted U-shaped spring piece 15 b are pressed against the inner wall surfaces on both sides of the groove 16.

また、前述したコンタクト１５は更に逆Ｕ字状ばね片１５ｂの外側辺の下端を外側方へ延長してその延長片で、プリント基板のパターンにリフロー半田により固定接続するための端子１３ｄを構成している。外殻体１２の両端外面に設けた金具１３は両側脚の下端に設けた固定片１３ａによりプリント基板に対してリフロー半田で固定され、また、中央片より外殻体１２を貫通させて外殻体１２内に突出させた突片をハウジング１１の両端外面下部に突設した凸部の上方に位置させ、ハウジング１１の上方への動きを規制するようになっている。   Further, the contact 15 described above further extends the lower end of the outer side of the inverted U-shaped spring piece 15b outwardly, and the extension piece constitutes a terminal 13d for fixed connection to the printed circuit board pattern by reflow soldering. ing. The metal fittings 13 provided on the outer surfaces of both ends of the outer shell body 12 are fixed to the printed circuit board by reflow soldering by fixing pieces 13a provided at the lower ends of both side legs, and the outer shell body 12 penetrates the outer shell body 12 from the central piece. The projecting piece projecting into the body 12 is positioned above the projecting portion projecting from the lower part of the outer surface of each end of the housing 11 to restrict the upward movement of the housing 11.

上述のように構成された従来例のコネクタは各コンタクト１５の端子１５ｄ及び金具１３の固定片１３ａをリフロー半田でプリント基板のパターンに半田付けすることにより、プリント基板に実装される。別のプリント基板に設けたコネクタのポスト１４を接合するに際してコネクタの取付けピッチに誤差があった場合には、ハウジング１１をコンタクト１５の逆Ｕ字状ばね片１５ｂを撓ませながら側方に移動させて誤差を吸収し、ポスト１４の位置とハウジング１１の挿入孔１０との位置を合わせ、スムーズな挿入接合ができるようになっている（特許文献１参照）。
特開平６−１６３１２５号公報（第３頁、図１） The conventional connector configured as described above is mounted on the printed circuit board by soldering the terminals 15d of the contacts 15 and the fixing pieces 13a of the metal fitting 13 to the printed circuit board pattern by reflow soldering. If there is an error in the connector mounting pitch when the connector post 14 provided on another printed circuit board is joined, the housing 11 is moved to the side while the inverted U-shaped spring piece 15b of the contact 15 is bent. Thus, the error is absorbed, and the position of the post 14 and the position of the insertion hole 10 of the housing 11 are matched to enable smooth insertion joining (see Patent Document 1).
JP-A-6-163125 (page 3, FIG. 1)

特許文献１に記載の従来例は、逆Ｕ字状ばね片１５ｂを弾性変形させることでハウジング１１が左右に移動し、基板同士の誤差吸収を図っているものであるが、コンタクト１５をハウジング１１に組み付けるときに、コンタクト１５の変形が生じ易く、コンタクト１５の端子１５ｄ（半田部分）に大きな応力が作用するおそれがあった。   In the conventional example described in Patent Document 1, the housing 11 moves to the left and right by elastically deforming the inverted U-shaped spring piece 15b to absorb errors between the substrates. When assembled, the contact 15 is likely to be deformed, and a large stress may be applied to the terminal 15d (solder portion) of the contact 15.

そこで、本発明は、コンタクト（端子）が大きく変形しても半田部分に直接大きな応力が生じないようにするとともに、簡易な構成でも両配線基板に設けた両コネクタの寸法誤差や基板同士の位置ずれを吸収できる配線基板用コネクタを提供することを目的とする。   Therefore, the present invention prevents a large stress from being directly generated in the solder portion even if the contact (terminal) is greatly deformed, and the dimensional error of both connectors provided on both wiring boards and the position between the boards even with a simple configuration. An object of the present invention is to provide a wiring board connector capable of absorbing the deviation.

上述の目的を達成するため、本発明は、相手方配線基板のコネクタ及び端子を収容するボックス状のコネクタが配設された可動ハウジングと、この可動ハウジングを変位可能に取り付けた固定ハウジングと、この固定ハウジングに固定された配線基板と、この配線基板に半田付けされ固定ハウジング内に位置して前記ボックス状のコネクタと接合された端子とを備えた配線基板用コネクタにおいて、前記配線基板に半田付けされた端子を逆Ｕ字状、続いてＵ字状に折り曲げて、基部から折曲部を介して延長部に続き、延長部の下端を折り曲げて折曲部から先端まで接触ばね片に形成し、この接触ばね片に前記ボックス状のコネクタを接合したものである。   In order to achieve the above-described object, the present invention provides a movable housing in which a box-shaped connector that accommodates a connector and a terminal of a counterpart wiring board is disposed, a fixed housing in which the movable housing is movably attached, and the fixed In a wiring board connector comprising: a wiring board fixed to a housing; and a terminal soldered to the wiring board and positioned in the fixed housing and joined to the box-shaped connector, the wiring board is soldered to the wiring board The terminal is bent into an inverted U shape, and then bent into a U shape, followed by the extension portion from the base portion through the bent portion, and the lower end of the extension portion is bent to form a contact spring piece from the bent portion to the tip, The box-shaped connector is joined to the contact spring piece.

本発明は、相手方配線基板のコネクタ及び端子を収容するボックス状のコネクタが配設された可動ハウジングと、この可動ハウジングを変位可能に取り付けた固定ハウジングと、この固定ハウジングに固定された配線基板と、この配線基板に半田付けされ固定ハウジング内に位置して前記ボックス状のコネクタと接合された端子とを備えた配線基板用コネクタにおいて、前記配線基板に半田付けされた端子を逆Ｕ字状、続いてＵ字状に折り曲げて、基部から折曲部を介して延長部に続き、延長部の下端を折り曲げて折曲部から先端まで接触ばね片に形成し、この接触ばね片に前記ボックス状のコネクタを接合したので、端子が大きく変形しても、すなわちＵ字状と逆Ｕ字状の各部分が撓んでも、その基板固定部分に直接大きな応力が生じない。そのため、端子の半田が剥離するおそれはなくなった。また、上述したような簡易な構成ではあるが、配線基板の位置ずれを吸収することができる。   The present invention includes a movable housing in which a box-shaped connector that accommodates a connector and a terminal of a counterpart wiring board is disposed, a fixed housing in which the movable housing is movably attached, and a wiring board fixed to the fixed housing, In the wiring board connector provided with a terminal soldered to the wiring board and positioned in the fixed housing and joined to the box-shaped connector, the terminal soldered to the wiring board is formed in an inverted U shape, Subsequently, it is bent into a U-shape and continues from the base portion through the bent portion to the extended portion, and the lower end of the extended portion is bent to form a contact spring piece from the bent portion to the tip. Because the connector is joined, even if the terminal is greatly deformed, that is, even if each U-shaped and inverted U-shaped part is bent, no large stress is directly generated on the board fixing part.Therefore, there is no possibility that the solder of the terminal is peeled off. Moreover, although it is the simple structure as mentioned above, the position shift of a wiring board can be absorbed.
