【考案の詳細な説明】
本考案は印刷配線板の差込み接続を容易とした印刷配線
板用コネクタに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for printed wiring boards that facilitates insertion and connection of printed wiring boards.
電子応用装置においては印刷配線板に設けた端子部を、
直接雄コンタクトとしてコネクタに差込むようにして、
印刷配線板上の回路相互、電源などと接続することが行
われている。In electronic application equipment, the terminal section provided on the printed wiring board is
Insert directly into the connector as a male contact,
Circuits on printed wiring boards are connected to each other and to power supplies.
ところでこの場合印刷配線板の接続回路数が多くなり、
これに伴ってコネクタの多極化が進むと、印刷配線板の
差込みに当って大きな力を要することになり、接続に大
きな困難を伴うことになる。By the way, in this case, the number of connected circuits on the printed wiring board increases,
As connectors become more multipolar, a greater amount of force is required to insert the printed wiring board, making the connection more difficult.
また接続回路数が多くなり印刷配線板の幅が大きくなる
と、第1図に示す斜視図のように、印刷配線板Pは回路
素子Eの取付面側に反り易くなり、その程度は幅が大き
くなればなる程大となる。Furthermore, as the number of connected circuits increases and the width of the printed wiring board increases, the printed wiring board P tends to warp toward the mounting surface of the circuit element E, as shown in the perspective view of Figure 1, and the degree of warping increases as the width increases. The more it becomes, the bigger it becomes.
このため反りが第2図に示す平面図のようにコネクタの
差込み口1aの幅より大きくなると、差込みができなく
なる欠点がある。For this reason, if the warpage becomes larger than the width of the insertion opening 1a of the connector as shown in the plan view of FIG. 2, there is a drawback that insertion becomes impossible.
本考案は以上の欠点を除去したコネクタの提供を目的と
してなされたもので、次に図面を用いてその詳細を説明
する。The present invention has been made with the aim of providing a connector that eliminates the above-mentioned drawbacks, and will now be described in detail with reference to the drawings.
第3図は本考案の一実施例を示す外観斜視図、第4図a
、 b、 cはそのA−A’部、33−B’部およびC
−C’部における矢視断面図であって、その特徴とする
ところは次の点にある。Fig. 3 is an external perspective view showing an embodiment of the present invention, Fig. 4a
, b, c are its A-A' part, 33-B' part and C
- It is a sectional view taken along the direction of arrow C', and its features are as follows.
その第1は第3図のように、雌コネクタの絶縁ハウジン
グ1の印刷配線板差込み口1aの設置面上の両端および
中央部に、それぞれ外側から差込み口1aの方向に下が
って差込口1aと連なる、V字形をなす誘導斜面2aを
備えた印刷配線板の反り矯正突部2を設けた点にある。The first is, as shown in FIG. 3, at both ends and in the center of the installation surface of the printed circuit board insertion port 1a of the insulating housing 1 of the female connector, and from the outside downwardly toward the insertion port 1a. The present invention is characterized in that a printed wiring board warp correction protrusion 2 is provided with a V-shaped guiding slope 2a that is continuous with the curved line.
なお、図中1b、2bは隔壁である。In addition, 1b and 2b in the figure are partition walls.
そしてこれにより印刷配線板の差込み口1aを実質的に
拡げて、反りがあっても第5図a、 bに示す平面図お
よび断面図のように、印刷配線板Pが誘導斜面2a内に
入り、更に差込みが続くことにより反った印刷配線板P
の中央部が、図中の矢印のように中央部の矯正突部2の
一方の誘導斜面2aにより差込み口1aの方向に押され
て、自動的に差込み口1a内に入るようにしたものであ
る。As a result, the insertion port 1a of the printed wiring board is substantially expanded, and even if there is a warp, the printed wiring board P can be inserted into the guiding slope 2a as shown in the plan view and cross-sectional view shown in FIGS. 5a and 5b. , the printed wiring board P warped due to further insertion.
The central part of the straightening protrusion 2 is pushed in the direction of the insertion opening 1a by one of the guide slopes 2a of the correction protrusion 2 in the central part, as shown by the arrow in the figure, and automatically enters the insertion opening 1a. be.
また第2には従来のように全コンタクトの接点部を一直
線上に配列することなく、一部のコンタクト3をその接
点部3aが矯正突部2内に突出する(絶縁ハウジング1
の印刷配線板差込み口端面より突出する)ように設けて
、第4図に示すように印刷配線板Pの差込み方向におい
て、矯正突部2のない部分に設けた他のコンタクト4の
接点部4aとの間に位置の差を設けた点にある。Second, unlike the conventional arrangement, the contact portions of all the contacts are not arranged in a straight line, but the contact portions 3a of some of the contacts 3 protrude into the correction protrusion 2 (the insulating housing 1
The contact portion 4a of the other contact 4 is provided so as to protrude from the end face of the printed wiring board insertion port of the printed wiring board P, and is provided in the portion where the correction protrusion 2 is not provided in the insertion direction of the printed wiring board P as shown in FIG. The point is that there is a difference in position between the two.
そしてこれにより第6図a、 bに示す断面図のように
、差込まれた印刷配線板Pの一部の端子部が上側に位置
したコンタクト3の接点部3aのそれぞれと先づ接触し
、更に続く差込みにより印刷配線板の残る端子部が、コ
ンタクト4の接点部4aに接触するようにして、印刷配
線板の差込みに要する力を少なくするようにした点にあ
る。As a result, as shown in the cross-sectional views shown in FIGS. 6a and 6b, some terminal portions of the inserted printed wiring board P first come into contact with each of the contact portions 3a of the contacts 3 located on the upper side, and The remaining terminal portion of the printed wiring board comes into contact with the contact portion 4a of the contact 4 by the subsequent insertion, thereby reducing the force required for insertion of the printed wiring board.
即ち差込みに要する力の大きさは、主として対向する接
点部をそのばね力に抗して開くに要する力によって決定
される。That is, the magnitude of the force required for insertion is mainly determined by the force required to open the opposing contact portions against the spring force.
従って例えば矯正突部2におけるコンタクト3の数を、
他のコンタクト4の数と同数とすれば、従来のように全
コンタクトの接点部を一列に配置した場合に比べて印刷
配線板の差込みに要する力を約172にすることができ
る。Therefore, for example, the number of contacts 3 in the correction protrusion 2 is
If the number is the same as the number of other contacts 4, the force required to insert the printed wiring board can be reduced to about 172 compared to the conventional case where the contact portions of all the contacts are arranged in a row.
これに加えて本考案では矯正突部2内にコンタクト3を
突出させて設けているので、その分だけコネクタの高さ
を小さくできる。In addition, in the present invention, since the contacts 3 are provided to protrude within the corrective protrusion 2, the height of the connector can be reduced accordingly.
また印刷配線板のコンタクトへの差込み長さは、印刷配
線板差込み口端面とコンタクト4までの深さによって決
まり、この深さはコンタクト3の矯正突部2内への突出
長さだけ短かくなるので、印刷配線板の差込み長さを短
かくできる。In addition, the length of insertion of the printed wiring board into the contact is determined by the depth between the end face of the printed wiring board insertion port and the contact 4, and this depth is shortened by the length of the contact 3 protruding into the correction protrusion 2. Therefore, the insertion length of the printed wiring board can be shortened.
従って印刷配線板の大きさを一定にした場合、それだけ
部品搭載面積を大きくできる。Therefore, if the size of the printed wiring board is kept constant, the area for mounting components can be increased accordingly.
従って本考案によれば、印刷配線板の接続回路数が多く
なり、またこれにより大形となって反りを生じても容易
にコネクタを差込むことができ、従来コネクタの欠点は
一掃される。Therefore, according to the present invention, the number of connected circuits on the printed wiring board increases, and even if the printed wiring board becomes large and warped, the connector can be easily inserted, and the drawbacks of conventional connectors are eliminated.
また機器の小形化の要求から、印刷配線板相互や他の回
路構成機器などが接近して設けられる場合が多い。Furthermore, due to the demand for smaller devices, printed wiring boards and other circuit components are often placed close to each other.
このため他の印刷配線板などに制約されて、充分な差込
み力を作用できない場合が多く、また差込み口が見えに
くい場合が多い。For this reason, it is often difficult to apply sufficient insertion force due to constraints from other printed wiring boards, and it is often difficult to see the insertion opening.
しかし本考案によれば差込み力を少なくできるばかりで
なく、差込み口の幅を実質的に拡げ、しかも誘導斜面に
よって印刷配線板を差込み口に誘導するようにしている
ので、機器の小形化が容易となる。However, according to the present invention, not only can the insertion force be reduced, but the width of the insertion port is substantially expanded, and the printed wiring board is guided to the insertion port by the guiding slope, making it easy to downsize the device. becomes.
また電源端子をもつ印刷配線板の場合、先づ電源端子を
除く端子部がコネクタに接続されて所要の回路が構成さ
れたのち、電源端子がコネクタに接続されて電源の供給
が行われることが、印刷配線板の搭載素子例えば搭載ト
ランジスタへの逆極性電圧の印加による破損防止のため
などに望ましい。In addition, in the case of a printed wiring board with power terminals, the terminals excluding the power terminals are first connected to the connector to configure the required circuit, and then the power terminals are connected to the connector to supply power. This is desirable for preventing damage caused by application of reverse polarity voltage to mounted elements, such as mounted transistors, on a printed wiring board.
しかし従来コネクタのように、全コンタクトの接点部を
一直線上に配列したものでは、微視的には各接点部は一
直線状ではなく、また印刷配線板は差込み口に対して傾
むいて差込まれるのを防ぎ得ない。However, in conventional connectors in which all the contact points are arranged in a straight line, microscopically, each contact point is not in a straight line, and the printed wiring board may be inserted at an angle to the insertion port. I can't prevent it from happening.
このため同時接続とはならないばかりか、電源端子が他
の回路端子より先に接続されて好しくない結果を生じ易
い。For this reason, not only are simultaneous connections not possible, but the power supply terminals are likely to be connected before other circuit terminals, resulting in unfavorable results.
そこで従来は例えば第7図に示す平面図のように、電源
端子TSの先端部を、他の回路端子T1、T2・・・T
Nの先端より後退するように作ることが提案されている
。Therefore, conventionally, for example, as shown in the plan view shown in FIG.
It has been proposed to make it set back from the tip of N.
しかしこの方法では従来採用されている印刷配線板の製
造行程に改変を加えなければならない。However, this method requires modifications to the conventional printed wiring board manufacturing process.
しかし前記した要領により電源回路が先に接続されては
困る回路を選出して、他の回路接続用のコンタクトを電
源回路接続用のコンタクトより上部に離して位置させる
ことにより、上記したように印刷配線板側において電源
端子と他の回路接続端子の差込み方向の位置を変えたり
することなく目的を遠戚できる。However, as described above, by selecting circuits for which it would be a problem if the power circuit is connected first, and locating the contacts for connecting other circuits higher than the contacts for connecting the power circuit, printing as described above is possible. The purpose can be distantly related without changing the positions of the power supply terminal and other circuit connection terminals in the insertion direction on the wiring board side.
以上本考案を一実施例について説明したが、例えば印刷
配線板の反り矯正突部2の高さを選定して、この中にコ
ンタクトの接点部をn段例えば2段に配列し、計3段配
置のコンタクト列を作って差込み力を約173にするこ
ともできる。The present invention has been described above with reference to one embodiment. For example, by selecting the height of the warpage correction protrusion 2 of a printed wiring board, the contact portions of the contacts are arranged in n stages, for example, two stages, for a total of three stages. It is also possible to create a row of contacts in the configuration to provide an insertion force of approximately 173 mm.
また以上の実施例では両端と中央部に印刷配線板の矯正
突部2を設けたが、中央部のものを両端間に分散して設
けることもできるなどの変形が可能である。Further, in the above embodiment, the correction protrusions 2 of the printed wiring board are provided at both ends and the center, but modifications are possible such that the correction protrusions 2 at the center can be provided dispersedly between both ends.
また以上では2本のコンタクトの接点部を対向配置した
場合について説明したが、第8図に示す断面図のように
1本のコンタクトを用いて形成されるコネクタにも本考
案を適用できる。Moreover, although the case where the contact portions of two contacts are arranged opposite to each other has been described above, the present invention can also be applied to a connector formed using one contact as shown in the sectional view shown in FIG.
以上の説明から明らかなように、本考案によれば大形で
あって接続回路数が多いばかりか反りのある印刷配線板
でも、少ない差込み力で容易に接続でき、しかも電源端
子と部品端子の接続時期の前後の不工合にもとづく素子
の破損を防ぐことができるなどの各種の利点を有する小
型な印刷配線板用コネクタを提供しうるもので、実用に
供してその効果は大きい。As is clear from the above explanation, according to the present invention, even printed wiring boards that are large, have a large number of connected circuits, and are warped can be easily connected with little insertion force. It is possible to provide a compact connector for printed wiring boards that has various advantages such as being able to prevent damage to elements due to defects before and after connection, and has great effects in practical use.
