る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a printed board connector used in electronic equipment such as computers or electronic exchanges.

最近の電子装置は使用する半導体素子の高集積化にとも
なつて実装形態も高密度化の一途をたどり、特にプリン
ト板コネクタに代表される接続部品に対して、小型化の
要求と同時に多極化が強く望まれている。In recent years, as the semiconductor elements used in recent electronic devices have become more highly integrated, the mounting formats have also become more dense.In particular, there has been a demand for miniaturization and multipolarization of connection parts, such as printed circuit board connectors. Highly desired.

従来の技術では２００−！Ｔｇｎの実装スペースの中か
ら１００〜１２晰の接続ポイントを取つている例が多い
が、高密度化装置を開発する場合上記実装スペー”ス中
から従来の倍、２叩極以上の接続ポイントが欲しいとい
う要求も出て来ており今後さらにこの要求は強くなつて
いくものと思われる。200-! with conventional technology! There are many cases in which 100 to 12 connection points are taken from the Tgn mounting space, but when developing high-density equipment, it is necessary to have twice the conventional number of connection points, 2 or more, from the above mounting space. There is a growing demand for this, and it is thought that this demand will become even stronger in the future.

本発明はこの要求に対し、従来技術の延長では対処出来
ない欠点を無くし、多極コネクタの実現を可能ならしめ
、装置実装の大巾な高密度化の推進に寄与するものであ
る。The present invention addresses this need by eliminating the drawbacks that cannot be addressed by extending the conventional technology, making it possible to realize a multi-pole connector, and contributing to the promotion of a wide range of high-density device packaging.

以下、図面を参照しながら、本発明を従来例と比較しな
がら詳細に説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail while comparing it with a conventional example with reference to the drawings.

第１図および第２図は従来プリント板コネクタＪの一例

ング、２は接点ばね、３はプリント基板、４はプリント
基板３の面取り部、５は面取り部４の肩部を表わす。1 and 2 show an example of a conventional printed board connector J, in which 1 is a housing made of a molded product, 2 is a contact spring, 3 is a printed circuit board, 4 is a chamfered portion of the printed circuit board 3, 5 represents the shoulder portion of the chamfered portion 4.

第１図はプリント基板３がハウジング１に徐々に挿入さ
れていく過程をＡ，ｂ，ｃの順に図示したものである。FIG. 1 illustrates the process in which the printed circuit board 3 is gradually inserted into the housing 1 in the order of A, b, and c.

第２図はプリント基板３がハウジング１に挿入されいく
過程におけるプリント基板３を挿入するために必要なり
（挿入力）を挿入距離との関係で表わしたものである。
第１図ｂの状態つまリプリント基板３の面取り部４に接

げ時第２図に示す様に挿入力が最大とある。例えば、従
来のプリント板コネクタでは接点ばね５０〜６師あたリ
プリント基板挿入時の最大挿入力は約７〜１０ｋ９位に
なる場合が多い。FIG. 2 shows the insertion force required to insert the printed circuit board 3 in the process of inserting the printed circuit board 3 into the housing 1 in relation to the insertion distance.
In the state shown in FIG. 1b, when the contact portion 2'' of the contact spring 2 slides on the chamfered portion 4 of the printed circuit board 3 and rides on the shoulder portion 5, the insertion force is at its maximum as shown in FIG. 2. For example, in conventional printed board connectors, the maximum insertion force when inserting a reprinted board with 50 to 6 contact springs is often about 7 to 10 k9.

さらに、前述のように２００Ｔｓｎ実装スペース中から
１００〜１２師の接続ポイント（５０〜６師のプリント
板コネクタ２個使用）を取るためにはプリント基板の挿
入力は最大で１４〜２０ｋ９が必要となり、人間の手作
業でプリント基板を挿入するたに要する力としては限界
に近い状態となつている。Furthermore, as mentioned above, in order to obtain 100 to 12 connection points (using two 50 to 6 board connectors) from a 200Tsn mounting space, a maximum insertion force of 14 to 20 k9 is required for the printed circuit board. The force required to manually insert a printed circuit board is almost at its limit.

多極化の要求から、今２０『実装スペース中から２凹極
以上の接続ポイントが得られる様なプリント板コネクタ
を従来技術の延長で考えた場合、プリント基板の挿入力
は１４〜２０ｋ９の倍近い値になることが予測され、手
操作でプリント基板が操入出来ないという致命的な欠点
となつてしまうことが明白である。Due to the demand for multi-polarization, if we consider a printed board connector that can obtain connection points of 2 or more recessed poles from the mounting space as an extension of conventional technology, the insertion force of the printed circuit board is almost twice that of 14 to 20k9. It is obvious that this will become a fatal drawback in that the printed circuit board cannot be operated manually.

また、第１図ｂの状態において接点ばね２の接点部２″

する上で欠点となることが予想される。Further, in the state shown in FIG. 1b, the contact portion 2'' of the contact spring 2
When the vicinity of the printed circuit board 3 slides against the exposed chamfer 4 of the printed circuit board 3 made of an insulating material (glass-filled epoxy or phenol, etc.), this condition occurs especially when the printed circuit board 3 is made of a material containing glass fiber. Since the contact portion 2'' is significantly worn, it is expected that this will become a drawback in ensuring long-term contact reliability due to the number of times the printed circuit board can be inserted or the adhesion of abrasion powder.

以上説明した通り、従来技術の延長て考えた場合には、
１ コネクタを多極化した場合、プリント基板の−挿入
力が手操作で行える限界を越えてしまう。As explained above, when considered as an extension of the conventional technology,
1. When a connector has multiple pins, the insertion force of the printed circuit board exceeds the limit that can be achieved manually.

２プリント基板を挿入する過程て接点ばねの接点部近傍
がプリント基板の面取り部分を摺動することによる接点
部近傍の摩耗およびその摩耗粉による接触信頼性の低下
。2. During the process of inserting the printed circuit board, the vicinity of the contact section of the contact spring slides on the chamfered portion of the printed circuit board, resulting in wear near the contact section and reduction in contact reliability due to abrasion powder.

この２つが大きな欠点となる。These two are major drawbacks.

本発明は、この２つ欠点を同時に解決できるプリント板
コネクタを提供したもので、以下第３図〜第６図に従つ

Therefore, they are arranged at a predetermined pitch, and the upper housing 10 is coupled to the lower housing 11 so as to be movable upward (in the direction of arrow a).
As shown in the figure, this joint structure connects both housings 10 and 1.
1 is formed into a step shape, and hook-shaped protrusions 18 and 1' formed at the tips of the steps are engaged with each other. The upper housing 10 includes a printed circuit board insertion opening 19 formed by a shoulder 17 and a through hole 20 into which the tip 16 of the contact spring 14 is inserted, and the shoulder 17 has an inclined surface 21 formed therein. . The cam plate 12 is housed in through holes 22 formed on both sides of both housings 10 and 11, and is attached to the lower housing 11 by a shaft 13 so as to be rotatable and to be freely removable into and out of the lower housing 11.

When removing the printed circuit board from the state shown in FIG. 5, either pull it out in this state, or use a jig to push the upper housing 10 back to the state shown in FIG. 4, and then pull out the printed board. It's fine if you do it.
